chore: release 0.9.0 — security hardening + warn-don't-block network policy

Release 0.9.0 covering the merged security/reliability PRs (#106 deps/ supply-chain, #107 auth/network, #108 test stability, #110 tmux cwd) plus: - Network policy: a non-loopback bind without CODEMAN_PASSWORD now STARTS with a loud warning (3 ways to secure) instead of refusing to start. Loopback stays the safe default. --allow-unauthenticated-network just acknowledges (terser note). (src/web/server.ts start()) - Post-install security note explaining the loopback default + safe exposure. - New docs/security-architecture.md documenting the full model (binding, auth pipeline, tunnel req.ip caveat, file-serving, supply-chain, isolation, recommended setups). CLAUDE.md Security section + gotcha updated. - Updated auth-security test: asserts warn-and-start (not throw). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

 # aicodeman

+## 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.
+
+## 0.6.0
+
+### Minor Changes
+
+- Community contributions from @aakhter:
+  - **feat (#66): Tab reorder shortcuts** — `Ctrl+Shift+{` and `Ctrl+Shift+}` move the active session tab left/right, matching WezTerm convention. Order persists across reloads via `saveSessionOrder()`.
+  - **feat (#67): Active tab visibility + Alt+N badges** — active tab now has a bright green border with color-matched glow, and the first 9 tabs display number badges hinting at the `Alt+N` switch shortcut. Badges update on reorder/rerender.
+  - **feat (#68): Clipboard API** — new `POST /api/clipboard` accepting `{text}` broadcasts a `clipboard:write` SSE event; connected browsers attempt `navigator.clipboard.writeText()` with a manual-copy modal fallback when the page isn't focused. Auth-protected via the standard middleware. Useful for pushing snippets from remote sessions to the user's local clipboard.
+  - **fix (#65): Android Shift+key double character** — pressing `Shift+A` on attached Android keyboards no longer produces "AA". Tracks xterm-handled keydown timestamps and skips the orphaned-input listener for 50ms after a real keydown, while still catching Gboard symbol-keyboard inputs (keyCode 229).
+
+## 0.5.13
+
+### Patch Changes
+
+- Fix "Case path not found" error in Quick Start when `~/codeman-cases/` does not exist (issue #64). Two bugs in `session-ui.js`:
+  - `runClaude()` auto-create read `createCaseData.case`, but `POST /api/cases` returns `{ success, data: { case } }` — corrected to `createCaseData.data.case`.
+  - `runShell()` had no auto-create logic and would immediately throw on a missing case directory — now mirrors `runClaude()`'s create-on-demand flow.
+
+## 0.5.12
+
+### Patch Changes
+
+- Fix quick-start to resolve linked cases before codeman-cases fallback. `/api/quick-start` was always resolving `caseName` against `CASES_DIR`, ignoring entries in `~/.codeman/linked-cases.json`. Sessions started via quick-start now correctly honour linked external project directories, consistent with regular case routes.
+
+## 0.5.11
+
+### Patch Changes
+
+- Community contributions and security hardening:
+  - Mobile response viewer: native-scroll panel for reading full Claude responses with markdown rendering via marked.js (PR #62)
+  - PWA support: service worker caching, web app manifest, and Android home screen install (PR #59)
+  - Named Cloudflare tunnel support (PR #58)
+  - Markdown rendering for response viewer with HTML sanitization (XSS prevention) — strips dangerous elements, event handlers, and javascript: URIs
+  - Service worker switched from stale-while-revalidate to network-first caching so deploys take effect immediately
+  - Content-Disposition filename sanitization to prevent header injection in file downloads
+  - Expose session.muxName public getter, replace unsafe `as any` cast in session-routes
+  - Static import for execFile in session-routes
+  - Keyboard shortcut updates: Alt+1-9 tab switching, Shift+Enter newline
+  - Repo restructure for cleaner GitHub landing page
+  - Mobile logo, expandable history, session resume fixes
+

 ## Common Gotchas

 - **Single-line prompts only** — `writeViaMux()` sends text+Enter separately; multi-line breaks Ink
 - **ESM only** — Never `require()`, use `await import()`. `tsx` masks CJS/ESM issues in dev but production breaks
 - **Package ≠ product name** — npm: `aicodeman`, product: **Codeman**. Release renames tags accordingly
- **Global regex `lastIndex`** — Use `createAnsiPatternFull/Simple()` factories, not shared `g`-flag patterns in loops
+- **Global regex `lastIndex`** — Shared `g`-flag patterns in loops must reset `lastIndex = 0` first, or use the `execPattern()` helper in `utils/regex-patterns.ts` (resets automatically)
+- **`envOverrides` flow `CLAUDE_CODE_*` / `OPENCODE_*` env vars** — Set via `POST /api/sessions { envOverrides }`, stored on `Session._envOverrides`, exported by `tmux-manager.buildEnvExports()` at spawn time, persisted in `SessionState.envOverrides`. **Do NOT** write these to `<case>/.claude/settings.local.json` — that's the old path and creates UI/disk drift
+- **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`
+- **Dual-CLI prefix discipline** — Codeman supports both Claude Code and OpenCode (`claude-cli-resolver.ts` / `opencode-cli-resolver.ts`); env-var prefix is CLI-specific (`CLAUDE_CODE_*` vs `OPENCODE_*`) and the allowlist in `schemas.ts` enforces this. When adding settings, decide which CLI(s) it applies to and gate the env export accordingly — don't blindly forward both prefixes. 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 duplicated** — the local-echo overlay lives in BOTH `packages/xterm-zerolag-input/src/` (published to npm as a standalone library for external consumers — see README "Published Packages") AND inline inside `src/web/public/app.js` (runtime copy the web UI actually loads, since the page ships as plain JS without a bundler). Any change to overlay behavior MUST be applied to both, or dev and prod diverge — and a public API break in the package warrants a separate version bump for `xterm-zerolag-input` in the changeset. Always test on mobile after touching it. 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', …)`.

+# 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.
+
+---
+
+## 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.
+A future hardening could gate the hook‑event exemption on a shared secret while a
+tunnel is active.
+
+---
+
+## 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`. With global `nosniff` + CSP `default-src 'self'`, other text types
+(`.html`, `.xml`, …) that fall through to `octet-stream` are not rendered as HTML
+either. 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.
+
+### 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` applies on every response:
+
+- `Content-Security-Policy: default-src 'self'` (widened only for `/gesture/`
+  assets when `CODEMAN_GESTURE=1`, to load self‑hosted MediaPipe)
+- `X-Content-Type-Options: nosniff`
+- `X-Frame-Options`
+- `Strict-Transport-Security` when served over HTTPS
+- CORS restricted to localhost origins
+
+---
+
+## 10. Quick reference
+
+| Env / flag | Effect |
+|------------|--------|
+| `CODEMAN_PASSWORD` (+ `CODEMAN_USERNAME`) | Enable HTTP Basic auth |
+| `--host` / `CODEMAN_HOST` | Bind host (default `127.0.0.1`) |
+| `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK` | Acknowledge an unauthenticated non‑loopback bind (downgrades the warning) |
+| `--https` | Enable TLS (adds HSTS) |
+| `CODEMAN_INSTANCE` | Scope tmux socket + data dir for isolation |
+| `CODEMAN_GESTURE=1` | Make the gesture overlay available (widens CSP) |
+
+**Audit log:** session lifecycle and server start are recorded in
+`~/.codeman/session-lifecycle.jsonl`.

+ * and the overlay fails to start). These are large binaries (~27 MB) kept OUT of
+ * git (ignored explicitly via `src/web/public/gesture/wasm/` + `*.task` in
+ * .gitignore); they are fetched here at install (postinstall) and build time.
+ *
+ * Idempotent: skips files already present. Non-fatal: the gesture overlay is
+ * opt-in (CODEMAN_GESTURE=1), so a fetch failure only warns — it must not break
+ * `npm install` / `npm run build`. The build then copies src/web/public into
+ * dist/ as usual, so prod gets these too.
+ *
+ * The @mediapipe/tasks-vision version MUST match the one bundled into the gesture
+ * overlay (Ark0N/codeman-gesture-control) so the wasm loader matches its JS API.

+ * same socket will discover and attach to the first instance's live sessions,
+ * and two instances sharing `~/.codeman/state.json` will clobber each other.

+ * To let a beta build coexist with a production one, this module derives both

+ *   - `CODEMAN_INSTANCE=foo`  → `~/.codeman-foo`  + `tmux -L codeman-foo`
+ *
+ * The DEFAULT is the production layout so this is safe to ship to master: an
+ * existing install keeps reading `~/.codeman`. To run a beta ALONGSIDE prod,
+ * launch it with `CODEMAN_INSTANCE=beta` (and a distinct port, see below) —
