docs: record the socket-resolution rule where the mechanism lives

CLAUDE.md gained "any new `tmux -L` caller through `resolveTmuxSocketName()`"
but architecture-invariants.md, which that bullet points at for the
mechanism, still described only the dataPath() half. Say why the rule
exists there too: the TUI is the first non-server process to shell out
to tmux.

+`npm test` is the same suite CI runs, so a green run locally means a green run there. It leaves out three suites that cannot pass on an arbitrary machine, each with its own command:
+
+```bash
+npm run test:browser   # Playwright + chromium (+ a live server; codex-predictive-echo needs a real codex binary)
+npm run test:mobile    # the above plus environment-specific PNG baselines
+npm run test:perf      # wall-clock benchmarks — run on an otherwise idle machine
+npm run test:all       # literally everything, environmental failures included
+```
+
+Expect `test:browser`/`test:mobile`/`test:perf` to fail where the machine cannot provide what they need; read that as "not runnable here", not as a regression. `config/test-suites.ts` holds the globs, and both configs derive from it, so the exclusions and those runners cannot drift apart.
 
 If you add a test that binds a port, pick a unique one at 3150 or above (search the repo for `const PORT =` first). Never 3000.

+
+### Patch Changes
+
+- Terminal input and scrollback fixes (PRs #327, #331):
+  - IME punctuation preserved (#327): keyCode 229 / `Process` key events are now delegated to xterm's CompositionHelper instead of being suppressed, so an active Chinese IME committing numbers and full-width punctuation (，。！？ and friends) reaches the terminal correctly. The CJK input field sends the browser's committed text instead of guessing from `KeyboardEvent.key`, and the redundant Android orphan-input fallback is removed so xterm is the single input owner.
+  - Shell history replay bounded (#331): selecting a Shell session loads a bounded 1 MiB tail instead of replaying the entire multi-megabyte tmux scrollback on xterm's main thread; full history stays available via the explicit "Load full history" action. tmux history limits now apply correctly on both legacy tmux (global default set in the same command queue before pane creation) and tmux 3.7+ (per-pane targeting that never resizes or trims unrelated live panes). Also adds `Server-Timing` and `[TERMINAL-PERF]` timing stages for terminal loads, fixes `scrollToLastNonEmptyLine` double-counting scrollback rows, and keeps live output ordered behind snapshot replays.
+
+  ### Thanks
+  - @dignfei for both fixes: the IME punctuation root-cause fix (#327) and the bounded shell history replay with the tmux history-limit correctness work (#331).
+
+## 1.20.0
+
+### Minor Changes
+
+- Response viewer for OpenCode, Gemini, Antigravity and Pi sessions (#326). External CLIs render their own TUIs, so the viewer used to come up empty for them; a new transcript parser (`response-viewer-transcript.ts`) reconstructs the conversation from the pane text instead, and the `?context=full` view now tags every block with a role so prompts render as "You" and agent output as the assistant. The divider normalizer was rewritten as a linear scan after review found catastrophic backtracking on agent-controlled input (minutes of stall on a long dash run), with an equivalence corpus pinning the old accept set.
+
+  CLIs installed via nvm or Homebrew are now found when Codeman runs as a service (#329). A shared resolver falls back to a login-shell probe when the direct PATH lookup misses, so systemd and LaunchAgent installs no longer report every CLI as missing. Review hardening on top: a failed resolution is negative-cached with doubling backoff instead of re-spawning a login shell on every request, all probes pass `killSignal: 'SIGKILL'` (interactive bash shrugs off SIGTERM, and a blocking `.bash_profile` could have hung the server indefinitely), the resolvers are inert under vitest again so test suites cannot execute binaries found on the dev box, and the improved not-found guidance is wired into both the session-create errors and the per-CLI status endpoints.
+
+  `GET /api/system/repo-status` reports branch, upstream, ahead/behind and remote reachability for git-clone installs (#328). Review hardening: the git network calls moved off the synchronous path onto a single-flight 45s cache (one slow remote could previously freeze the whole server for up to a minute per request), remote URLs and git stderr are credential-redacted before they leave the server, the spawns use the same non-interactive git env as the clone path, and a local-branch upstream no longer parses into garbage.
+
+  Auto Copy for the terminal (#325, opt-in, per-device): a finished selection (mouse drag, double or triple click, or a phone long-press) lands on the clipboard by itself, so select-then-copy becomes select. Alongside it, hand-encoded tap reports are now gated on the server-observed `cliMouseTracking` state, so a pane that has fallen back to a plain shell no longer receives `[<0;88;20M` junk on tap.
+
+  The Ralph loop no longer stops polling after two ticks (#330): the reschedule guard read a stale timer handle that the timer callback never cleared, so the loop silently died while its status stayed `running`. The handle is now nulled as the callback's first statement, and a regression test pins the bug.
+
+  The red "needs you" tab alert clears when a dialog is answered in the terminal instead of surviving until the end of the turn: the post-hook re-capture could erase the parsed dialog options that the staleness sweep relies on (`applyCapture` is now add-only for options), and a delayed staleness pass now runs while a page is open. The unreachable `copyTerminal()` was removed, closing out #322.

+  ### Thanks
+  - @aakhter contributed the external-CLI response viewer (#326), the repo-status endpoint (#328), the login-shell CLI resolution (#329) and the Ralph reschedule fix (#330)

+
+## 1.19.7
+
+### Patch Changes
+
+- Mobile catches up: links open from a tap, terminal text can be selected and copied, long prompts stay visible while you type. Plus Files panel search, a bundled Nerd Font symbols fallback, and a per-device terminal font setting.
+  - **Terminal and chat links work on phones** (#321): tapping a URL or file path in terminal output now opens it (new tab, file preview, or log viewer), resolved through the same provider desktop hover uses, so tap and click can never disagree about what is a link. Dialog rows and the composer keep their existing meaning. Response-viewer links open in a new tab with `rel="noopener noreferrer"` instead of navigating the dashboard away. Wrapped links open whole: the logical-line reconstruction now stitches hard wraps through the indent their continuation carries, which also fixes desktop hover-click truncating wrapped URLs.
+  - **Terminal text can be copied on touch devices** (#321): long-press selects the token under the finger, drag or tap the other end to extend, and a small bar offers Copy, Line (the whole logical line, wraps included) and dismiss. Copy works on plain-HTTP installs too. Three guards keep the keyboard down and the selection alive through the browser's own long-press handling.
+  - **A long prompt stays visible on phones** (#321): the local-echo overlay grows upward once it would run past the last visible row (a prompt taller than the screen keeps its tail, where the cursor is), and the keyboard-driven padding shrink can no longer reclaim the space the fixed toolbar and accessory bar stand in.
+  - **Files panel search** (#324): `GET /api/sessions/:id/files?q=...` answers a flat match list (name or path substring, `*`/`?` globs), recursing past non-matching directories with its own match cap on top of the existing bounds; without `q` the response is byte-identical to before. Glob queries are matched without regex so a pathological pattern cannot stall the server.
+  - **Nerd Font prompt glyphs out of the box, custom terminal font** (#320): a bundled icons-only Symbols Nerd Font Mono fallback renders powerlevel10k/starship/oh-my-posh glyphs on every device with no font install, and App Settings gains a per-device terminal font family that is prepended to the built-in stack.
+
+  ### Thanks
+
+  Three contributor PRs in one release: thanks to @rounakdatta (#321), @aakhter (#324) and @comzine (#320).
+
+- 8a54b33: Clear every production-reachable npm advisory, and fix a service-worker caching regression the upgrade exposed.
+
+  `npm audit` reported 20 advisories, but 16 were devDependencies-only (Remotion, Puppeteer, postcss, the eslint/tsx toolchain) and never reached anyone installing the package. Four reached production and are now resolved:
+  - **`@fastify/static` 9.1.3 to 10.1.3** — GHSA-8pvw-jcv7-9cmj, authorization bypass via non-canonical URL paths. The advisory covers `<=10.1.1`, so the entire 9.x line is affected and the fix only exists on 10.x.
+  - **`find-my-way` 9.6.0 to 9.8.0** — GHSA-c96f-x56v-gq3h (HTTP/2 DDoS). Not exploitable here since Codeman does not enable HTTP/2, fixed anyway.
+  - **`fast-uri` 3.1.2 to 3.1.5** — GHSA-v2hh-gcrm-f6hx, host confusion via a literal backslash authority delimiter.
+  - **`brace-expansion` to 5.0.9 / 1.1.18** — GHSA-3jxr-9vmj-r5cp, exponential-time expansion DoS.
+
+  The last three were transitive and only needed a lockfile re-resolve; no `overrides` were added.
+
+  The `@fastify/static` major changes the `setHeaders` callback's first argument from a Node `ServerResponse` to a `FastifyReply`, which required two fixes:
+  - `res.setHeader()` became `reply.header()`. A v9-style body throws `TypeError: res.setHeader is not a function` from inside the plugin on every static request.
+  - **That change also flips precedence, silently.** The callback used to write to the raw response and be overwritten by the route's staged reply headers; it now writes to the reply and wins instead. That handed `/sw.js` a year of `immutable` in place of the `no-cache, no-store` its route sets, which would pin a service worker on every client with no server-side way to recover. A route that already set `Cache-Control` now keeps it.
+
+  `ws` also appears in `npm audit` but production is already on 8.21.0, outside the vulnerable range; the only affected copy is bundled under `@remotion/renderer` and is dev-only.
+
+  Adds `test/static-cache-headers.test.ts`, which drives a real server and covers the caching contract that had no test at all, and moves the floors in `test/dependency-security.test.ts` up to the patched versions.
+
+## 1.19.6
+
+### Patch Changes
+
+- Wiki user manual, a phone tab tap-zone fix, per-parent lineage colours, and two robustness fixes.
+  - **Wiki**: `docs/wiki/` is now a 30-page user manual (installation, quick start, the dashboard, agent CLIs, remote/Docker cases, hooks, security, HTTP API, troubleshooting and more), published to the GitHub wiki by a sync workflow on every push that touches it.
+  - **Phone tabs**: on a narrow phone the active tab's geometric centre could land on its gear icon, so a thumb aiming at the tab opened Session Options instead of switching. The active tab's name now reserves a minimum width, and a static test recomputes the clearance from the stylesheet so widening the icons fails there rather than on a phone.
+  - **Lineage lines**: the arcs between a tab and the tabs it spawned are now coloured per SPAWNING tab, so every arc leaving one tab shares a colour and the strip reads as "these came from w1, those from w2". A child that spawns in turn gets its own colour, so a chain changes colour at each generation.
+  - **File access**: `validateSessionFilePath()` now canonicalizes the workspace as well as the candidate path before comparing them. Resolving only the candidate made a workspace reached through a symlink (`/tmp` on macOS, symlinked project dirs, bind-mounted case paths) report a spurious escape and refuse every read and write in that session. Escapes are still refused.
+  - **Respawn**: a cycle step that is stopped mid-write no longer revives the state machine. `stop()` could land during the `await` on the kickstart / update / clear / init write, after which the controller set itself back to a waiting state and kept running.
+
+  ### Thanks
+  - @aakhter for the symlink-safe workspace confinement fix (#314) and the respawn stop-race fix (#315).
+
+- 98e37bf: Session List Layout gains a third option, "Left sidebar", whose rows carry the same per-session detail the home screen shows.
+
+  The sidebar previously had one row style: a name and a folder. That is the whole story a tab can tell, but a docked column is not a tab strip — it has width to spare and a row per session either way, and the information that was missing is exactly the information the desktop home rail and the phone overview already put on screen. So the new option lifts it onto the rows: when the session was first created, how long it has been in the state it is in, and a status pill naming that state.
+  - The old "Left sidebar" is now **"Left sidebar simple"** and is unchanged, down to the byte — the stored value stays `sidebar`, so anyone already using it keeps exactly the layout they chose. The new option is `sidebar-rich`.
+  - Both sidebar values are the SAME layout and both set `data-session-list="sidebar"`; row detail rides on a separate `data-sidebar-detail` attribute. That is deliberate: every `isSessionSidebarActive()` call site and every `html[data-session-list="sidebar"]` rule in styles.css and mobile.css keeps matching both, untouched.
+  - Which state a session is in, and which stamp measures it, come from `_mobileOverviewState()` / `_mobileOverviewSince()` rather than being re-derived — the sidebar, the home rail and the phone overview cannot disagree about what "working" means. A working row is measured from the turn's last Enter, not from its last repaint, so a running turn reads `working 12m` instead of `0m`.
+  - The stamps refresh in place on a 20s clock instead of re-rendering: a rebuild would restart every load spinner and alert animation in the list, twice a minute. The clock only runs while rich rows are on screen.
+  - The column widens to 300px for the extra line, and the collapsed 44px rail and the handheld drawer are explicitly held back from that width.
+
+- 947ff6f: `npm test` is now the CI gate and is safe to run bare; the suites it cannot run each got their own command.
+
+  `npm test` ran the everything-config, which fails ~87 tests on a clean master on any machine without chromium, a free port and per-machine PNG baselines. That made the repo's most obvious command useless as a pass/fail signal, and the docs had accumulated "never run bare `npm test`" warnings in four files to work around it. It now runs `config/vitest.ci.config.ts` — exactly what CI runs — so local green means CI green.
+  - New: `test:browser` (5 Playwright files), `test:perf` (2 wall-clock benchmarks), `test:all` (the old everything-behaviour, kept reachable). `test:ci` and `test:mobile` are unchanged; `test:watch` and `test:coverage` follow `test` onto the gate's config.
+  - The exclusion list moved to `config/test-suites.ts`, with the reason each suite cannot run in CI. Every config derives from it, so the gate's excludes and the runners' includes cannot drift.
+  - That drift was a silent hole, not a tidiness problem: a file excluded from CI and added to no runner is tested by NOTHING, and every command stays green, because vitest counts "no files matched" as success. `test/test-suite-partition.test.ts` now fails if any test file is reachable by no runner or by two.
+  - ⚠️ A file filter must match its runner: `npm test -- test/mobile/keyboard.test.ts` matches nothing and exits green having run zero tests, because the gate excludes that path. Use `npm run test:mobile -- <file>`. Documented in CLAUDE.md, and the one place that recommended the old form was corrected.
+  - Docs synced: CLAUDE.md, AGENTS.md, .github/CONTRIBUTING.md, both READMEs, and two ci.yml comments that claimed only `test/mobile/**` was excluded (it is three suites, and 5 Playwright files rather than 3).
+
+## 1.19.5
+
+### Patch Changes
+
+- Closing the session you are looking at now always moves you to the next tab.
+
+  The delete request and its own `session_deleted` broadcast raced each other: the close path selected the next tab, while the broadcast handler cleared the active session and showed the home screen, and whichever ran first decided what you saw. On one build, closing a tab either switched sessions or dumped you on the welcome screen depending on timing. The close now owns that handoff from beginning to end, and the broadcast handler stays out of the way for a close started in that tab. A session deleted from somewhere else still returns you to the home screen, which is the honest answer when what you were looking at was taken away.
+
+  The next tab is also picked from sessions that still exist, so a stale entry in the tab order can no longer name a tab that is already gone.
+
+## 1.19.4
+
+### Patch Changes
+
+- Only a human opening a session clears its yellow "waiting for input" tab alert.
+
+  1.19.2 made that clear durable and cross-device, which also meant the app itself could spend it: restoring your last session on page load, a popped-out window opening its target, and the fallback to another tab after you close the active one all counted as "I checked it", so a yellow tab could clear itself before you ever saw it. Those three app-driven selections are now marked and skip the acknowledgement, so the alert survives until you actually open the session.
+
+  Everything a human does still clears it, on every surface: tapping a tab, tapping a row on the phone home screen, the keyboard tab shortcuts, and submitting a prompt into the session. The flag defaults to user-initiated, so a selection path nobody marked keeps acknowledging rather than leaving an alert nothing can clear.
+
+## 1.19.3
+
+### Patch Changes
+
+- Red "needs you" tab alerts now follow the dialog instead of the keyboard.
+
+  Typing in the terminal no longer clears a red alert. It used to clear every pending alert on the device you typed on, but a permission or question dialog ignores keystrokes that are not one of its options, so the dialog was still open and still blocking: the other devices stayed red and a reload brought the red back on the first one. Input now spends the yellow idle alert only, and it does that through the server-side acknowledgement added in 1.19.2, so the clear is durable and reaches every device.
+
+  A dialog answered in the terminal now clears by itself. Claude Code fires no "permission answered" hook, so the item stayed pending until the whole turn ended, and any page load in between re-armed a red alert for a dialog that was long gone. Listing approvals now re-captures the pane and resolves items whose dialog is no longer on screen, using the same conservative check the answer path already uses: only an item whose original frame parsed numbered options can be dropped this way, so an unreadable capture keeps the alert rather than losing a live one. Measured against a real AskUserQuestion dialog: the stale item cleared 5 seconds ahead of the stop hook that used to be the only signal, while a dialog still on screen survived 11 consecutive listings over 55 seconds untouched.
+
+## 1.19.2
+
+### Patch Changes
+
+- Yellow "waiting for input" tab alerts now stay cleared once you have checked them, on every device.
+
+  Viewing a session used to clear its idle alert in that browser's memory only. The server-side approval store still held the prompt, so the next page load seeded the alert straight back and a tab you had already checked went yellow again, while your other devices never heard about the click at all. Opening a session now acknowledges its pending idle prompt server-side (`POST /api/approvals/session/:sessionId/viewed`, a new `acknowledgedAt` field on approval items, broadcast as `approval:updated`), so the clear survives reloads and reaches every connected client.
+
+  Acknowledgement is deliberately not resolution: the prompt is still unanswered, so the item stays in the Approvals Inbox, stays answerable, and stays available as Read My Mind context, it just stops arming the tab alert. Permission and question dialogs are never acknowledged this way, since looking at a dialog does not answer it, so the red "needs you" alert survives being viewed. Clicking the tab you are already on now clears the alert as well; that path returned early before, so an alert armed on the active tab could not be cleared by clicking at all.

+## Terminal UI (`codeman tui`)
+
+A full-screen dashboard for your sessions, in the terminal. Same states as the web UI, because it is a client of the same server:
+
+```bash
+codeman tui              # the dashboard
+codeman tui --list       # numbered session list, then exit (scriptable)
+codeman tui 2            # attach straight to session 2 of that list
+```
+
+Sessions are grouped **NEEDS YOU → WORKING → IDLE → RECENT**, longest-waiting first. `↑↓`/`j`/`k` select, `1`-`9` and `[`/`]` switch between sessions, `Enter` attaches into the tmux pane (**`F1`** to come back). Inside a pane the bar across the top keeps the session strip visible and `Alt+1`-`Alt+9` switch without leaving. `y`/`n`/digit answer a pending permission dialog right from the list, `p` sends a one-line prompt, `n` starts a session and opens straight into it, `x` kills one (`y` confirms), `/` searches, `g` shows the away digest, `?` is help, `q` quits. Below 72 columns it drops the preview pane and becomes a single-column list, so it stays usable in Termius on a phone. With no server running it still starts in attach-only degraded mode.

+The web UI remains the primary surface; see **[docs/tui.md](docs/tui.md)** for the full guide.

-**Full-scrollback replay** (COD-164/#148, reworked for #205): `GET /api/sessions/:id/terminal?full=1` returns the ENTIRE tmux scrollback (capture-pane `-e -S -<lines>` bounded by the configured history limit, explicit `maxBuffer` from the terminal-history config, early byte-cap before normalization, CRLF-normalized for shell panes). On success the capture is returned ALONE (`source='mux-full-history'` — it supersedes the byte buffer; no duplication). The first load OF EACH SESSION per page load requests `full=1` (`_fullHistoryLoaded` Set in app.js — the old one-shot `_initialFullBufferLoad` flag was consumed by whichever tab auto-selected, leaving every other tab one frame of history); later switches keep the cheap `?tail=` visible-frame path. On top of that, scrolling up while already at the TOP of the buffer re-pulls `full=1` on demand (`_maybeRefetchFullHistory`, 4s per-session cooldown, in-flight + tab-switch guards, viewport position held across the replay). The re-pull exists because xterm's buffer is only a WINDOW onto tmux's history and two things shrink it: tmux coalesces bursty output into pane REPAINTS that overwrite rows instead of emitting linefeeds (measured: a 60-line burst added 1 row of browser scrollback and destroyed 34), and a tab switch replays only the visible frame. tmux's own history is intact throughout — the browser just has to ask for it again. On-demand rather than automatic because at a 100k history limit the capture can be megabytes. ⚠️ **The re-pull must never DOWNGRADE the buffer** (#205 round 2): the same reasoning that makes it a win for a shell pane makes it destructive for a repaint-mode CLI pane, where tmux keeps no history of its own (`history_size≈0` measured for a Claude pane) and the capture is roughly ONE frame while xterm may hold hundreds of rows of replayed frames — `_resetTerminalForReplay()` + rewrite then deletes history mid-scroll ("goes back a bit, repeats blocks, gets worse the further up I go"; measured A/B on a live pane: 341 rows → 42 with the guard off). `_replayWouldShrinkBuffer()` (terminal-ui.js) estimates the capture's rendered rows — escape sequences stripped, `capture-pane -J` re-wrapping accounted for — and the pull is skipped when that is more than one screen short of `buffer.active.length`. The one-screen tolerance matters: both sides are estimates (the buffer length counts trailing blank rows), so only a clear downgrade is refused. A refused session joins `_fullHistoryRepullUseless`, raising its cooldown from 4s to 60s so a hollow pane stops re-fetching megabytes on every scroll-up.

The first load of each non-shell TUI session per page requests `full=1` (`_fullHistoryLoaded` Set in app.js — the old one-shot `_initialFullBufferLoad` flag was consumed by whichever tab auto-selected, leaving every other TUI tab one frame of history). Shell sessions instead load a bounded 1 MiB `?tail=` window on every selection: a 100k-line shell capture can be tens of MiB, and automatically parsing it makes tab-switch latency scale with the entire session. Shell full history is therefore explicit-button-only; reaching the top during an ordinary wheel/touch gesture must not reset xterm and replay the multi-megabyte capture on its main thread. Other modes may still re-pull `full=1` at the TOP, and pressing **Load full history** forces the request for any recoverably truncated session (`_maybeRefetchFullHistory`, 4s per-session gesture cooldown, in-flight + tab-switch guards, viewport position held across the replay); Shell full pulls are not retained in the tab cache, so the next switch stays bounded. Chunked replay enqueues 32 KiB pieces across safe yields, appends an xterm parse marker, then releases the live-output gate; output arriving after that release stays ordered behind the snapshot, while the marker callback supplies accurate parse timing without extending the pre-existing queued-event discard window. The route exposes capture/prepare totals in `Server-Timing`, while `[TERMINAL-PERF]` separates TTFB, body/JSON, reset+parse and total time for both selection and on-demand full pulls; parse completion is not a browser compositor/GPU paint measurement. The re-pull exists because xterm's buffer is only a WINDOW onto tmux's history and two things shrink it: tmux coalesces bursty output into pane REPAINTS that overwrite rows instead of emitting linefeeds (measured: a 60-line burst added 1 row of browser scrollback and destroyed 34), and a tab switch replays only the visible frame. tmux's own history is intact throughout — the browser just has to ask for it again. On-demand rather than automatic because at a 100k history limit the capture can be megabytes. ⚠️ **The re-pull must never DOWNGRADE the buffer** (#205 round 2): the same reasoning that makes it a win for a shell pane makes it destructive for a repaint-mode CLI pane, where tmux keeps no history of its own (`history_size≈0` measured for a Claude pane) and the capture is roughly ONE frame while xterm may hold hundreds of rows of replayed frames — `_resetTerminalForReplay()` + rewrite then deletes history mid-scroll ("goes back a bit, repeats blocks, gets worse the further up I go"; measured A/B on a live pane: 341 rows → 42 with the guard off). `_replayWouldShrinkBuffer()` (terminal-ui.js) estimates the capture's rendered rows — escape sequences stripped, `capture-pane -J` re-wrapping accounted for — and the pull is skipped when that is more than one screen short of `buffer.active.length`. The one-screen tolerance matters: both sides are estimates (the buffer length counts trailing blank rows), so only a clear downgrade is refused. A refused session joins `_fullHistoryRepullUseless`, raising its cooldown from 4s to 60s so a hollow pane stops re-fetching megabytes on every scroll-up. Tests: `test/tmux-capture-full-history.test.ts`, `test/tmux-scrollback-eol.test.ts`, `test/terminal-scroll-routing.test.ts`.
 
 ### Terminal scrollback: strip flavors and wheel/touch forwarding
 
-**Two strip flavors, one carry** (#205, `session.ts:_handleTerminalOutput`): the FULL strip (`isAltScreenStripMode` = codex/claude/gemini) removes alt-screen toggles, `3J`, and mouse-tracking DECSETs. Every other mode (shell/opencode/antigravity/pi) gets the NARROW strip (`isMuxAltScreenOnlyStripMode`) — alt-screen toggles ONLY — and only when tmux-backed (`useMux`). Rationale: the tmux CLIENT emits `smcup` as its first bytes at attach, before any program runs, parking xterm in the scrollback-less alternate buffer for the whole session (touch scrolling no-ops; xterm's own wheel handler converts the wheel to Up/Down arrows = readline history cycling — both #205 symptoms). tmux never forwards a pane program's alt-screen toggles to its client (it repaints instead; measured — vim/less inside a pane emit zero to the client), so the only thing the narrow strip ever removes is tmux's own smcup. It keeps `3J` (a user's `clear` is a deliberate scrollback wipe) and the mouse DECSETs (tmux passes those through even with `mouse off`; stripping them would break htop/vim mouse support). ⚠️ The `useMux` gate is load-bearing: `startShell()`/`startInteractive()` fall back to a DIRECT PTY when mux creation fails, and there the inner program's own `?1049h` really does reach xterm — stripping it would break vim/less/htop for real. The replay path (`session-routes.ts`, via `session.usesMux`) applies the same narrow branch; the frontend `_sessionUsesServerMouseStrip()` mirror stays claude/codex/gemini because only the FULL strip touches mouse DECSETs. The chunk-boundary carry (`_altScreenSeqCarry`) runs for both flavors. Tests: `test/claude-scrollback-strip.test.ts`.

-**Only claude ≥ 2.1.187 forwards the wheel; every other mode scrolls local scrollback** (#227 follow-up, `terminal-ui.js:_shouldForwardWheelToApp`). Codex was in the forward list until a reporter hit a completely dead wheel in codex tabs while the scrollbar drag worked. Measured against codex-cli 0.147.0 in a bare tmux: it never enables mouse tracking (`mouse_any_flag=0`) and SGR wheel reports fed to its PTY change nothing on screen, because it runs an INLINE viewport (`alternate_on=0`) and pushes its transcript into the terminal's own scrollback (tmux `history_size` grows) instead of paging in-app. So for codex, local scrollback IS the transcript and forwarding swallowed every tick. ⚠️ "The TUI is a strip mode" is NOT evidence that it consumes wheel reports — verify with a real `\x1b[<64;c;rM` write into a live pane before adding a mode here. Hand-encoded SGR TAPS stay enabled for codex (`_sessionUsesServerMouseStrip`); measured, they are no-ops that insert nothing, so click-to-position is simply unavailable there rather than harmful.
+⚠️ **What the full strip removes, it must REMEMBER.** Stripping the mouse DECSETs means xterm's `modes.mouseTrackingMode` is permanently `'none'` for those modes, so the browser hand-encodes click reports to compensate (`_sendSyntheticSgrTap`). With no state to consult it did that on EVERY click, which delivered mouse reports to programs that never asked for them: the same pane runs a plain shell whenever the CLI has exited or a `shell` was started inside a claude-mode session, and a shell prints the report as literal text (`[<0;88;20M`), garbling the next line typed. `_recordStrippedMouseMode()` therefore records each stripped sequence as it goes and publishes `cliMouseTracking` through `toState()`, and `_shouldReportMouseToCli()` requires it. ⚠️ Only the TRACKING modes count (1000/1001/1002/1003): 1005/1006 select an ENCODING and 1007 is alt-scroll, and counting those would put the stray reports straight back. ⚠️ The change broadcasts IMMEDIATELY rather than through `broadcastSessionStateDebounced`, because the flag flips when a dialog opens and the user can click that dialog inside the 500ms debounce window. Measured on a live claude 2.x: the CLI holds a tracking mode on continuously (so clicks keep being reported exactly as before), while a bash prompt in the same stripped mode reports nothing. Fails toward silence: after a server restart the flag is false until the CLI re-emits, which tmux does at client attach.

Hand-encoded SGR TAPS are gated by `_shouldReportMouseToCli()` (strip mode AND the server-observed `cliMouseTracking` flag, recorded by `_recordStrippedMouseMode` in session.ts as it strips): codex never enables mouse tracking, so since #325 no tap report is sent there at all — click-to-position was already a measured no-op in codex, and a pane that has fallen back to a shell no longer receives `[<0;88;20M` junk.
 
 **Wheel/touch forwarding is NOT gated on viewport-at-bottom** (#205, `terminal-ui.js:_shouldForwardWheelToApp`): for sessions verified to scroll their own transcript on SGR wheel reports (claude ≥ 2.1.187 — version via the local/docker/remote `--version` probes), the plain wheel AND touch drags forward as coalesced SGR reports (`_forwardScrollToApp` → `_sendSyntheticSgrWheel`, 40ms batches, 5-tick cap, 512-byte queue bound). It used to gate on the viewport being at the bottom so both scrollbacks stayed reachable, but a repaint-mode CLI keeps NO terminal scrollback of its own — xterm's buffer holds only replayed repaint frames, so local scrolling drags the CLI's pinned prompt box up the screen over stale frames; and `scrollToLastNonEmptyLine()` routinely parked the viewport off-bottom, silently pinning the wheel to local. Forwarding now snaps the viewport home first (SGR coordinates address the LIVE screen — a report computed from a scrolled-up viewport would hit-test the wrong row). Local scrollback remains on Shift+wheel and the `terminalWheelLocalScrollback` opt-out (both also cover touch via the shared gate; touch has no Shift, so the setting is its only local pin). `_wheelScrollLines()` normalizes `deltaMode` (Firefox fires LINE deltas ≈3/notch — read as pixels that rounded to 0 and fell to the ±1 fallback, ~4× too slow; PAGE deltas scale by `terminal.rows`) while keeping the #154 Shift-axis trap (macOS trackpads put Shift+scroll magnitude on deltaX). Tests: `test/terminal-touch-tap.test.ts`.

 Copy goes through `_copyText()` (Clipboard API, then hidden-textarea + `execCommand`), not raw `navigator.clipboard`, because `install.sh`'s LAN option serves plain HTTP where `navigator.clipboard` is undefined; the fallback steals focus, so the terminal is refocused afterwards. Related: xterm registers its own `copy` listener on the terminal element gated on `hasSelection()`, which is why right-click → Copy has always worked. Selection itself is unavailable on touch devices by design (`user-select: none` on the terminal subtree), and in `shell`/`opencode`/`antigravity` tabs the TUI owns the mouse, so selecting there needs Shift+drag. Tests: `test/terminal-copy-selection.test.ts` (gate + wiring invariants), `test/terminal-copy-shortcut.test.ts` (browser, real key presses).
 
+### Auto Copy (copy-on-select)
+
+**Auto Copy** (`autoCopySelection`, per-device, default OFF) puts a finished terminal selection on the clipboard without a keystroke. It is a thin layer over the smart-copy machinery above and shares `_copyText()` with it, but the two paths differ in every decision that matters:
+
+- **It fires at the END of a gesture, never on selection change.** `onSelectionChange` runs for every cell a drag crosses, so copying there would be one clipboard write per mouse move. The callback only ARMS `_autoCopyPending`; the flush is a document-level `mouseup` listener installed once in `initTerminal`, plus explicit calls from the touch selection path.
+- **The flush is synchronous inside the handler.** Both clipboard paths need user activation: Firefox gates `navigator.clipboard.writeText` on it, and `document.execCommand('copy')` (the plain-HTTP fallback that `install.sh`'s LAN option lands on) has to run in the gesture's own task. Deferring to a timer or waiting for `onSelectionChange` loses it, and the failure is browser-specific and invisible in Chrome.
+- **The listener is on `document`, not the terminal container**, because a drag that ends outside the terminal (sweeping up past the header) delivers its mouseup to the document. Unrelated mouseups elsewhere on the page are filtered by the decision helper, not by the listener's target.
+- **Touch has its own entry point.** `_endTouchSelectionGesture()` and `_selectTouchSelectionLine()` call the flush directly, because the touch path `preventDefault()`s its touchend (that is what stops the compat mouse pair from stealing the selection back), so no mouseup ever reaches the document there. Without those two calls the toggle is simply dead on a phone.
+- **It must NOT do what `copyTerminalSelection()` does.** That one clears the selection (so a second `Ctrl+C` is an interrupt) and focuses the terminal. Clearing would make text vanish from under the cursor that just highlighted it, and focusing opens the on-screen keyboard over it on a phone. Focus is instead RESTORED to whatever held it before the copy, which only matters for the `execCommand` fallback (it focuses a temp textarea on the way through); the Clipboard API path never moves focus at all.
+
+`decideAutoCopy()` (constants.js, pure) holds the guards: setting off, blank or whitespace-only text (what a drag across empty cells produces), and a `AUTO_COPY_MAX_CHARS` (1M) cap. ⚠️ The cap is not decoration: a drag off the top of the viewport autoscrolls, so one gesture can sweep the whole 50k-line scrollback. Past it the copy is REFUSED rather than truncated, with a toast pointing at `Ctrl+C`, which still copies everything through the explicit path.
+
+⚠️ **Two dedupe rules, and both earn their place.** A genuine selection change (`pending`) always copies, so re-selecting the same text after copying something else in between still works. Otherwise only text differing from the last auto-copy does, which is what stops an unrelated mouseup from re-copying a stale selection AND what makes the first copy of a drag work at all: xterm fires `onSelectionChange` from its own document `mouseup` handler, and listener order between the two is registration order, not something this code controls. Gating on `pending` alone silently drops that first copy.
+
+Feedback is silent on success except ONCE per page load (a feature that works by doing nothing visible cannot otherwise be told from a dead toggle); failures and refusals toast, throttled to 10s so a permanently blocked clipboard cannot paint a toast on every drag. The setting is per-device on both counts required by the settings rule: it is in `displayKeys` AND absent from the `.strict()` `SettingsUpdateSchema` (clipboard access differs by device and by origin, and the plain-HTTP LAN install has no `navigator.clipboard` at all). Tests: `test/terminal-auto-copy.test.ts`.

 ### Settings surface: App Settings, Session Options, Add Case
 
 **One visual language, three modals.** `#appSettingsModal`, `#sessionOptionsModal` and `#createCaseModal` share the `set-*` surface (left rail, sections of grouped row cards, label + description on the left, control pinned right) through a single `:is(#appSettingsModal, #sessionOptionsModal, #createCaseModal)` scope in `styles.css`. An `:is()` list takes the specificity of its **most specific argument**, and all three arguments are ids, so every rule kept exactly the weight it had when the block was `#appSettingsModal`-only: nothing downstream shifted in the cascade. That property is what let the surface absorb Session Options and then Add Case in two separate commits without a cascade audit each time.

+# Codeman TUI Rework Plan
+
+Status: **phases 0-2 implemented** on `feat/tui`; phases 3-4 remain follow-ups. The user guide is [`docs/tui.md`](tui.md); this document stays the design record.
+
+- Phase 0: `src/cli-style.ts` (palette, glyphs, `heading`/`kv`/`table`/`spinner`/`confirm`) plus the mechanical fixes of §5, and `test/cli-commands.test.ts` now derives its inventory from the real commander `program` instead of parsing a fixture.
+- Phases 1-2: `src/tui/`. `tui-app.ts` (main loop, attach handoff, verbs) and `tui-client.ts` (API, SSE, degraded enumeration) are the only IO; `tui-model`, `tui-layout`, `tui-render`, `tui-keys`, `tui-ansi`, `tui-composer`, `tui-approvals`, `tui-digest`, `tui-sse` and `tui-types` are pure and unit-tested, with an E2E suite driving the real binary under node-pty.
+- Deferred with the rest of phase 3: `r` (resume a RECENT row) is not wired up, so the help overlay does not advertise it.
+- Not started: phase 3 (mouse, `--pick` popup switcher, opt-in attach status line, OSC 9) and phase 4 (retiring the bash choosers).
+
+The goal: replace Codeman's scattered terminal surfaces with one first-class TUI, `codeman tui`, that gives SSH/terminal users the same at-a-glance awareness the web UI gives browsers. The reference point is herdr (herdr.dev), the trending Rust "agent multiplexer" whose defining feature is a live agent-state sidebar. Codeman can match and beat that sidebar in the terminal because the states herdr infers from screen-scraping heuristics are states our server already computes from hooks, pane probing, and the approvals inbox.
+
+---
+
+## 1. What we have today (inventory)
+
+Three disconnected surfaces, three visual idioms, two data sources:
+
+| Surface | What it is | Data source | Idiom |
+| --- | --- | --- | --- |
+| `codeman` CLI (`src/cli.ts`, 1214 lines) | commander + chalk, ~20 commands | HTTP API + state files | `✓`/`✗` line-per-fact, no interactivity |
+| `sc` (`scripts/tmux-chooser.sh`, 663 lines) | bash number-menu chooser, mobile-tuned (44 cols) | `tmux -L codeman` + `state.json` via jq | 256-color, numbered, full repaint per key |
+| `scripts/tmux-manager.sh` (529 lines) | bash cursor TUI with kill/info | `mux-sessions.json` (and writes it back) | 8-color, box-drawn, arrow keys |
+
+Weaknesses found in the audit (file:line refs verified 2026-08-16):
+
+1. **No interactive picker in the Node CLI at all.** Every `session stop`, `task status`, `session logs` requires a pasted UUID prefix. There is no `codeman attach <session>`; `codeman attach` is actually the attachment-card command (and `README.md:895` describes it wrongly).
+2. **`sc` cannot reach sessions 10+ interactively**: entries are numbered globally (`tmux-chooser.sh:343`) but input accepts a single `[1-9]` keypress (`:487-493`). Page 2 shows items 8-14 that mostly cannot be selected.
+3. **No cursor/selection concept in `sc`** (`BG_SEL` at `:90` is dead code); arrows only page.
+4. The two bash tools can disagree about which sessions exist (different data files), and only `sc` is on PATH.
+5. **Zero live feedback anywhere**: `codeman web -d` and `service install` block silently up to 30s (`daemon-control.ts:395-412`); no spinner exists in the codebase.
+6. Styling drift: `doctor` is the only table and is deliberately monochrome with a colorize hook nobody wired up (`dependency-report.ts:5-7`); `codeman web` prints its "running at" line twice (colored `cli.ts:934`, plain `server.ts:2366`); the server's security warning is colorless `console.warn` while the CLI's version of the same warning is yellow; `tmux-manager.sh`'s header box is visibly misaligned; `padEnd(14)` overflows on "Antigravity CLI".
+7. Bash TUIs emit raw escapes unconditionally (no TTY/NO_COLOR gate); `install.sh` and `postinstall.js` do it right.
+8. Detach hint inconsistency: chooser says Ctrl+B D, `README.md:671` says Ctrl+A D.
+9. Inside an attached session there is **no chrome at all**: Codeman turns the tmux status bar off (`tmux-manager.ts:1978`), so an SSH user in a pane has no session identity, no state, no way back to a picker except detach.
+10. `test/cli-commands.test.ts` asserts against a hand-written fixture, not the real `program`, and that fixture already lists a `tui` command that does not exist (`:57-61`). The name is pre-approved by our own test file.
+
+## 2. Research: how herdr does it
+
+herdr (github.com/herdrdev/herdr, ~30k stars, single Rust binary, pre-1.0) is a background terminal multiplexer "your coding agents live on". What matters for us:
+
+- **The agent-state sidebar is the product.** Every pane is classified live as `working` / `blocked` / `done` / `idle` and grouped in a sidebar, so you see who needs you without switching tabs. Reviews unanimously call this "the killer feature tmux can't match".
+- **Detection is heuristic-first**: process-name matching + screen-manifest TOML rules parsing the visible frame; optional per-agent "integration install" adds lifecycle hooks over JSON-RPC on a unix socket for accurate states. Claude Code there is on the heuristic path and reviewers note blocked-state lag.
+- **Model**: workspaces → tabs → panes, tmux-style prefix keys (Ctrl+B V split, arrows navigate, D detach), mouse-first (click select, drag resize, right-click menus, touch over SSH), adapts to narrow widths.
+- **Agent-shaped API**: socket API with `pane read` (visible/recent/detection), `send-text`/`send-keys`/`run`, `agent start|prompt|wait|explain`, `pane wait-output` with regex, plugins placed as overlay/split/tab/popup.
+- **Persistence**: sessions survive disconnects, reattach from any terminal / SSH.
+- Weaknesses reviewers cite: pre-1.0 churn, bus factor 1, no session resurrection, rendering lag with many panes.
+
+What is striking is how much of herdr Codeman already has, server-side: our hooks give exact `permission_prompt`/`stop`/`idle_prompt` events (herdr's "integration" path, but installed by default), `_confirmIdle()` does the screen-probe fallback, the approvals inbox parses the actual dialog options, and the agent skill + wait primitives are our socket API. What we lack is purely the presentation layer in the terminal.
+
+Prior art for the architecture we want: **agent-deck** (Bubble Tea + tmux) proves the "TUI list + attach into tmux" model works great: session list with live glyphs (● ◐ ○ ✕), Enter attaches into a tmux pane, status polling, groups, fuzzy search. We take the shape, not the code.
+
+Licensing note: herdr is reported variously as Apache-2.0/AGPL-3.0. Irrelevant either way: we copy concepts, never code.
+
+### What we take / what we skip
+
+Take: the four-state sidebar as the organizing principle; grouping by "needs you first"; narrow-width adaptation; mouse support; tmux-familiar keys; the "attention at a glance" framing.
+
+Skip: being a multiplexer. tmux already backs every Codeman session and is a hard dependency; herdr had to build pane management because it owns terminals, we do not. Also skip (for now): plugin marketplace, split layouts, pane drag. Our TUI is a **dashboard + switchboard over tmux**, not a tmux replacement.
+
+## 3. Design: `codeman tui`
+
+One command, one full-screen client of the existing HTTP/SSE API.
+
+**Positioning (owner decision, 2026-08-16): the web UI remains THE primary surface.** The TUI is strictly additive, for users who want a terminal workflow (SSH, Termius, tmux die-hards). Bare `codeman` keeps printing help; nothing existing changes behavior. The `sc` bash chooser also stays untouched for now; flipping its alias to `codeman tui` is deferred to a follow-up release once the TUI has mileage.

+
+- **Header**: hostname/instance, server version, session count, plan-usage chip (same telemetry that feeds the web chip, when available). Degrades gracefully when the server is down (see §3.6).
+- **Sidebar**: sessions grouped `NEEDS YOU` → `WORKING` → `IDLE` → `RECENT` (past sessions from the unified list, resumable). Within groups, reuse the activity ordering already built for the home screens in PR #303 (blocked first, running longest, quiet newest); that logic is pure and shared.
+- **Preview pane**: live tail of the selected session, SGR colors preserved, cursor-movement stripped. When the selected session has a pending approval, the parsed dialog is rendered as a card above the tail with one-key answer bindings.
+- **Footer**: contextual keymap (changes when a dialog/confirm is active).
+
+### States and vocabulary
+
+Exactly the web's language so the two surfaces read the same:
+
+| Group | Glyph | Color | Source |
+| --- | --- | --- | --- |
+| NEEDS YOU (question/permission) | `⚠` | red, blinking row | approvals inbox / `permission_prompt` |
+| NEEDS YOU (waiting for input) | `✋` | yellow | `idle_prompt` / waiting classification |
+| WORKING | `✻` animating through `· ✢ ✳ ∗ ✻ ✽` at 2Hz | green | working classification (the same glyph family Claude itself draws, a deliberate nod) |
+| IDLE | `○` | muted | idle |
+| RECENT / done | `✔` | muted green | unified list history rows |
+
+Nerd-font/glyph fallback exactly like `sc` does today (`[!] [w] [*] [-] [ok]` when the terminal is not known-capable), plus full NO_COLOR / `tput colors` degradation (8-color and mono renderings are designed, not accidental).
+
+### Keymap
+
+- `↑/↓` or `j/k` select · `Enter` attach · `1-9` jump-attach (parity with `sc`, but now the cursor covers 10+)
+- `y`/`n` (or the digit keys) answer the selected session's pending approval right from the dashboard, via `POST /api/approvals/:id/answer`. The server already re-captures the pane and 409s if the dialog is gone, so this is safe by construction.
+- `p` send a one-line prompt to the selected session without attaching (`POST /input` with `\r`, the composer opens in the footer)
+- `n` new session (case picker → mode picker, drives `POST /api/quick-start`) · `x` kill with typed confirm (never bulk; refuses the session hosting the TUI itself, like tmux-manager.sh does)
+- `/` fuzzy search across sessions/history/attachments (`GET /api/search`) · `g` away digest (`GET /api/away-digest`) rendered as a panel
+- `r` resume selected RECENT row (unified list `resume-session` flow) · `?` help overlay · `q` quit
+- Mouse (phase 3): SGR mouse reporting, click selects, wheel scrolls list/preview, click on footer keys triggers them. Works over SSH, same as herdr's touch story.
+
+### Responsive behavior
+
+The `sc` design constraint survives: below ~72 cols (Termius, iPhone portrait) the preview pane drops and the TUI is a single-column list with two-line rows, nearly identical to today's `sc` but with a cursor, live states, and the answer/prompt/new/kill verbs. The layout switch is width-driven at draw time, no mode flag.
+
+### Attach model
+
+Enter suspends the TUI (restore main screen + cooked mode), then hands the terminal to `tmux -L <socket> attach-session -t <name>` with `stdio: inherit`. On tmux exit/detach, the TUI resumes and refreshes. Full fidelity (mouse, paste, colors) is tmux's, we never proxy bytes.
+
+- Inside tmux already: same socket → `switch-client -t`; different socket → warn about nesting and offer detach-first. `$TMUX` + `CODEMAN_MUX` detection.
+- **Return path**: a tmux binding installed for codeman sessions (opt-in) runs `codeman tui --pick` inside `tmux display-popup -E`, a minimal picker-only mode (list + jump, no preview) so switching sessions from inside a pane is one keystroke, fzf-style.
+- Optional per-attach chrome (opt-in setting, default off since `status off` at `tmux-manager.ts:1978` is deliberate): a minimal codeman-styled tmux status line showing `name · state · alert`, set on attach, restored on detach.
+
+### Notifications
+
+While the TUI is open and a session flips to NEEDS YOU: flash the row, ring BEL, and optionally emit OSC 9 (desktop notification in kitty/WezTerm/iTerm2, and it traverses SSH). This is the herdr sidebar promise delivered even when the terminal is backgrounded.
+
+### Degraded mode (server down)
+
+`sc` works without the server today and the TUI must too: when no server answers, enumerate `tmux -L codeman list-sessions` + read `state.json` (read-only), show a "server not running" header line, and offer attach only (no states, no approvals). This keeps the "web server crashed, get me to my sessions" path alive.
+
+## 4. Architecture
+
+### A client of the server, not a second brain
+
+Everything live comes from the API the web UI already uses:
+
+| Need | Endpoint |
+| --- | --- |
+| Session list + history | `GET /api/sessions/unified` |
+| Live updates | SSE `GET /api/events` (heartbeat `sse:heartbeat` already exists; fall back to 2s polling) |
+| Pending approvals + parsed options | `GET /api/approvals`, answer via `POST /api/approvals/:id/answer` |
+| Preview tail | `GET /api/sessions/:id/terminal?tail=N` (throttled to the selected session only) |
+| Prompt send | `POST /api/sessions/:id/input` (single line + `\r`, per the composer contract) |
+| New session | `POST /api/quick-start` (routes remote/docker cases correctly) |
+| Search | `GET /api/search` |
+| Away digest | `GET /api/away-digest` |
+| Plan usage chip | latest status-telemetry snapshot (`plan-usage-latest`) |
+
+Server discovery and auth reuse what exists: instance config from `src/config/instance.ts` (`CODEMAN_INSTANCE`, `CODEMAN_PORT`), the probe logic from `daemon-control.ts`, credentials from `~/.codeman/.env` (the established `codeman attach` pattern), self-signed HTTPS accepted for loopback probes (the hooks-on-HTTPS lesson). Multi-user scoping comes free: the API only returns what the authenticated user owns.
+
+### Renderer: hand-rolled, zero new dependencies (decision)
+
+Options considered:
+
+- **Ink (React for CLIs)**: what Claude Code uses. Pros: layout engine, ecosystem. Cons: pulls React into a CLI that today ships only commander+chalk; rerender model fights the two things we care most about (a raw-ANSI preview region and 2Hz glyph animation without flicker); version-pins React for every `npm i -g aicodeman`.
+- **blessed/neo-blessed**: unmaintained, skip.
+- **Hand-rolled screen core** (recommended): this repo hand-rolls ANSI everywhere already and has the expertise (regex-patterns, stripAnsi, the xterm work). The core is small and boring: alt screen + raw mode + cursor-home full-frame repaint from an off-screen string buffer, throttled to state changes and the 2Hz animation tick, wrapped in DECSET 2026 (synchronized output) where supported so repaints are atomic in modern terminals (tmux, kitty, WezTerm, iTerm2). No diffing needed at these frame rates.
+
+The one genuinely tricky pure function: SGR-aware line clipping for the preview (keep colors, strip cursor movement/OSC/DECSET, clip to width while carrying SGR state, reset at EOL). That is a pure module with exhaustive unit tests, and it is exactly the kind of function Ink would not have given us anyway.
+
+### Module layout
+
+```
+src/tui/
+  tui-app.ts        entry + main loop + attach handoff (IO)
+  tui-client.ts     API + SSE client, degraded-mode enumeration (IO)
+  tui-model.ts      pure: state store, grouping, ordering (reuses PR #303 helpers)
+  tui-layout.ts     pure: responsive layout math, row building
+  tui-render.ts     pure: model+layout -> frame string (palette, glyphs, fallbacks)
+  tui-keys.ts       pure: byte stream -> key/mouse events (incl. SGR mouse decode)
+  tui-ansi.ts       pure: SGR-aware clip/filter for the preview
+```
+
+Pure modules unit-test with no TTY. `cli.ts` gains one thin `tui` command registration (and `--list`/`<n>` fast paths for `sc -l` / `sc 2` parity, which must stay fast: they short-circuit before any screen setup).
+
+## 5. CLI-wide polish (the rest of "make it much nicer")
+
+A shared style kit, `src/cli-style.ts`: one palette (mirroring the web's status colors), one glyph set with fallback, `heading()`, `kv()`, `table()` (width-aware, fixes the Antigravity overflow), `spinner()` (finally: the 30s silent daemon/service waits get a live line), `confirm()` (used by `reset --force`'s missing prompt and `x` in the TUI). Then the mechanical fixes from §1: colorize `doctor` through the hook that already exists for it, dedupe the `codeman web` startup line, colorize the server's security warning, fix the README `codeman attach` description and the Ctrl+B/Ctrl+A detach drift, TTY/NO_COLOR gates everywhere.
+
+## 6. Phasing
+
+| Phase | Contents | Size |
+| --- | --- | --- |
+| 0 | `cli-style.ts` + mechanical fixes (§5), real CLI tests (retire the fixture parser in `test/cli-commands.test.ts`) | S |
+| 1 | `codeman tui` core: list + states via SSE, cursor + 1-9, attach/return loop, kill w/ confirm, new session, narrow mode, degraded mode, `sc` alias flip + `--list`/`<n>` parity | M/L |
+| 2 | Preview pane (SGR clip), approvals answering, prompt composer, search, digest, resume, plan-usage header | M |
+| 3 | Mouse support, `--pick` popup switcher + tmux binding, opt-in attach status line, BEL/OSC 9 notifications | M |
+| 4 | Retire `tmux-chooser.sh`/fold `tmux-manager.sh` (keep as thin wrappers for one release), docs/README/wiki, screenshots for promo | S |
+
+Phases 0-1 are the useful minimum; 2 is where it beats herdr's sidebar (answering approvals from the dashboard); 3 is delight.
+
+## 7. Testing
+
+- Pure modules (`tui-model/layout/render/keys/ansi`): plain vitest, frame snapshots as stripped strings plus targeted ANSI assertions.
+- Interactive E2E: spawn the built TUI under `node-pty` (already a dependency), feed keys, assert on captured frames; the vitest tmux mock (`IS_TEST_MODE`) keeps attach paths inert. Port rules per CLAUDE.md (3150+, `app.inject()` where possible by testing `tui-client` against injected routes).
+- Manual: Termius/iPhone portrait (the 44-col case), tmux nesting, server-down mode, NO_COLOR, non-nerd-font terminal.
+
+## 8. Invariants this plan respects
+
+- tmux socket and data dir always via instance config (`dataPath()`, `-L codeman`); a beta instance TUI sees only its own world.
+- Never bulk kill, always confirm, never touch another session implicitly, refuse killing the session the TUI runs in (w1/w2/w3 are sacred).
+- Input is single-line with `\r`, via the server (never raw tmux send-keys from the TUI while the server owns the session).
+- Approvals answering goes through the server's re-capture + 409 path, never blind keystrokes.
+- `status off` on panes stays the default; any chrome is opt-in.
+- No new runtime dependencies; the npm package stays light.
+
+## 9. Decisions (resolved 2026-08-16)
+
+1. **Bare `codeman` does NOT open the TUI** (owner decision): the web UI is the main thing, the TUI is additional. `codeman tui` only.
+2. **`sc` stays the bash chooser for now**; the alias flip is a follow-up once the TUI has mileage. `codeman tui --list` / `codeman tui <n>` provide the same fast paths for people who want to switch.
+3. Opt-in tmux status line: deferred to phase 3 along with the `--pick` popup switcher.
+4. Preview tail goes over the API (auth/multi-user/remote-consistent); previews are simply unavailable in degraded server-down mode.
+5. Name is `codeman tui` (the test fixture historically expected it).
+
+Initial PR scope: phases 0-2. Phase 3 (mouse, popup switcher, status line, OSC 9) and phase 4 (bash chooser retirement) are follow-ups.

+# Terminal UI (`codeman tui`)
+
+`codeman tui` is a full-screen dashboard for your Codeman sessions, in the terminal.
+It shows every session grouped by whether it needs you, lets you answer a permission
+dialog or send a prompt without switching anywhere, and puts you inside a session's
+tmux pane with one keystroke.
+
+It is **additional, not a replacement**: the web UI stays the primary surface and
+gets every feature first. The TUI exists for the terminal workflow (SSH, Termius,
+a tmux window you keep open all day), and it is a *client* of the running server,
+so the two surfaces can never disagree about what a session is doing. It is also
+not a multiplexer: tmux still owns every pane, and attaching hands the terminal to
+tmux rather than proxying bytes.
+
+## Starting it
+
+```bash
+codeman tui              # the dashboard
+codeman tui --list       # print the numbered session list and exit
+codeman tui 2            # attach straight to session 2 of that list
+```
+
+The two fast paths are the scriptable ones (they are the `sc -l` / `sc 2` shapes).
+Neither sets up a screen, so both are as quick as the one API call they make, and
+`--list` prints plain text when piped, so it composes with `grep`/`awk`.
+
+What it needs:
+
+| Needs | What you get |
+| --- | --- |
+| **Full features** | A running Codeman server (states, approvals, preview, prompts, search, digest). The TUI finds it the way `codeman attach` does: `CODEMAN_API_URL`, else loopback on `CODEMAN_PORT` for this `CODEMAN_INSTANCE`. The self-signed certificate an `--https` install generates is accepted, as it is everywhere else in the CLI. |
+| **Server down** | It still starts, in **degraded mode**: sessions are enumerated straight from `tmux -L codeman` plus a read-only peek at `state.json`, and attach is the only verb. See [Troubleshooting](#troubleshooting). |
+| **A terminal** | `codeman tui` refuses to run when stdin/stdout are not a TTY, and says to use `--list` instead. A cron job or a pipe therefore fails loudly rather than emitting escape codes into a log. |
+
+## What it looks like
+
+A real frame at 100x30 (`NO_COLOR`, trailing blank rows trimmed). The selected
+session has a pending permission dialog, so the preview pane leads with the card:
+
+```

+
+- **Header**: the machine, the server version, how many sessions are live, and the
+  plan-usage chip (the same statusLine telemetry that feeds the web chip, when the
+  server has a snapshot). A `⚠ n` badge counts pending approvals.
+- **Sidebar**: every session, grouped and numbered.
+- **Preview**: a live tail of the selected session, its own colors preserved, with
+  the parsed dialog card on top when that session is blocked.
+- **Footer**: only the keys that work right now. `n` reads `n new` normally and
+  `n deny` when the selected session has a dialog, because it cannot be both.
+
+The same world through `--list`:
+
+```
+  1 waiting w6-docs         /home/you/dev/docs
+  2 blocked w4-api-refactor /home/you/dev/api
+  3 working w1-codeman      /home/you/dev/codeman

+  5 idle    w3-promo        /home/you/dev/promo
+  6 done    api-hotfix      /home/you/dev/api
+```
+
+The numbers are the same on both surfaces, so `codeman tui --list` then
+`codeman tui 4` is one thought.
+
+## The four groups
+
+Groups are always in this order, and a session is in exactly one of them:
+
+| Group | Glyph | Means | Comes from |
+| --- | --- | --- | --- |
+| **NEEDS YOU** | `⚠` | A permission or question dialog is blocking the agent | The approvals inbox (`permission_prompt` hooks, with the on-screen options parsed) |
+| | `✋` | Waiting for your next instruction, or errored | `idle_prompt`, or an errored session (equally something only a human clears) |
+| **WORKING** | `✻` animating | A turn is running | The same working classification the web dashboard uses |
+| **IDLE** | `○` | Live, but sitting there | |
+| **RECENT** | `✔` | A past session from the unified list | History rows, no live pane |
+
+Ordering inside a group is "the one that has waited longest, first": blocked
+sessions sort by how long the dialog has been up, working sessions by when their
+turn started (the pane's last Enter, since a working pane repaints every second
+and would otherwise always look freshly started), and quiet ones by last activity.
+That is the ordering the web home screens already use.
+
+The cursor sticks to a **session**, not a row number, so a session that jumps to
+NEEDS YOU does not drag your selection with it. The number beside each row is what
+`1-9` and `codeman tui <n>` mean, and it is renumbered on every re-sort.
+
+When a new dialog appears, the terminal bell rings once, for that dialog only: the
+same item announced twice does not ring twice.
+
+## Keymap
+
+| Key | Does |
+| --- | --- |
+| `↑` `↓` or `j` `k` | Move the cursor. PageUp/PageDown jump five rows. |
+| `Enter` | Attach to the selected session (see [Attaching](#attaching)) |
+| `1`-`9` | Jump to that row and attach. When a dialog is on screen, a digit answers it instead (see below). |
+| `y` | Approve the selected session's dialog |
+| `n` | Deny it, or **start a new session** when there is no dialog |
+| `p` | Send one line to the selected session without attaching |
+| `x` | Kill the selected session; `y` confirms, any other key cancels |
+| `/` | Search sessions, events and files |
+| `g` | Away digest: what happened while you were gone |
+| `?` | Help overlay |
+| `Esc` | Close whatever overlay is open |
+| `q` or `Ctrl+C` | Quit, restoring the screen you started with |
+
+Inside the `p` composer and the `/` query: `←` `→` `Home` `End` `Delete`
+`Backspace` plus `Ctrl+A` / `Ctrl+E` / `Ctrl+U` / `Ctrl+W`, `Enter` to send or open,
+`Esc` (or `Ctrl+C`) to cancel. In the kill confirmation you retype the session name;
+anything else cancels. In the `n` pickers, type to filter, `Enter` chooses.
+
+Verbs that need the server (`y`/`n`/`p`/`x`/`/`/`g`) say so in degraded mode
+instead of failing silently; `Enter` and `1-9` keep working.
+
+### `p` sends exactly one line
+
+The composer is a single line by design, ending in a carriage return: that is the
+input contract every Codeman path follows, because multi-line text breaks the
+agent's own composer. Pasted newlines become spaces rather than being rejected, so
+a paste cannot silently run a different command than the one you read.
+
+## Answering approvals
+
+This is the thing the terminal could not do before. Select a blocked session and:
+
+- `y` approves.
+- `n` picks the parsed "No" option, or sends Esc when the dialog did not parse one.
+- A digit picks that numbered option, **but only a digit the dialog actually
+  offers**. A digit with no matching option falls through to the list's own
+  jump-and-attach binding, so it can never be typed at whatever has focus.
+
+The answer goes through `POST /api/approvals/:id/answer`, which **re-captures the
+pane before it types anything**. If the dialog is no longer on screen (you answered
+it in tmux a moment ago, or the agent moved on), the server refuses with a 409 and
+the TUI says `that dialog is no longer on screen` rather than pressing a key into a
+live composer. The answer is scoped to the options the server parsed off the actual
+frame, never to a guess.
+
+An idle prompt (`✋`) is not a dialog: there is nothing to approve, so `p` is the
+reply path and the footer says `p reply` instead of `p prompt`.
+
+## Attaching
+
+`Enter` suspends the dashboard (main screen back, cooked mode back) and hands the
+terminal to tmux with `stdio: inherit`. Colors, mouse and paste are tmux's, at full
+fidelity.
+
+**Press `F1` to come back.** One key, no modifier to hold or release, nothing to
+type in a particular order. tmux's own way out is a chord — press the prefix, let
+go, then a letter — and beta testing showed that is genuinely hard to convey: the
+bar first named the wrong letter (tmux binds lowercase `d` to `detach-client` and
+capital `D` to `choose-client`), and once corrected it still failed for anyone who
+kept Ctrl held, because that sends `Ctrl+D`, which tmux leaves unbound. So the TUI
+claims `F1` in tmux's prefix-less key table for the length of the attach and gives
+it back afterwards. The chord still works; it is simply not what you are told to
+press.
+
+You do not have to remember any of it. For as long as the attach lasts the pane
+wears a bar across the top:
+
+```
+ 1 w3-codeman-…  2 w4-codeman-…  3 testcase …     alt+1-9 switch · F1 back to the codeman dashboard
+```
+
+That is the **session strip**: the other sessions stay visible from inside a pane,
+numbered exactly as the dashboard numbers them, with the one you are in inverted.
+`Alt+1`..`Alt+9` switch between them without going back to the dashboard first. With
+more sessions than fit, the strip shows a window around the current one and marks
+each cut end with `…`; the way-out hint is measured first and always keeps its space.
+
+Codeman keeps the status bar off on its panes (the web UI carries that information
+around the terminal instead), so the TUI turns it on for the attach and puts it back
+exactly as it was on detach, along with each window's size. Every session the strip
+can switch to is dressed and sized the same way, so switching is instant and lands
+in a pane that already fills your terminal.
+
+Detaching leaves the agent running; typing `exit` or pressing `Ctrl+D` would end it,
+which is the difference the bar exists to make obvious. If an agent does exit, its
+pane stays as a corpse: the TUI refuses to attach to a dead pane and offers `r` to
+resume the conversation in a fresh one instead.
+
+Three cases:
+
+| Where you are | What happens |
+| --- | --- |
+| Not in tmux | `tmux -L codeman attach-session` |
+| Already in tmux on Codeman's socket | `switch-client`, so you do not nest |
+| In tmux on a **different** socket | Refused, with an explanation: detach from that tmux first, then run `codeman tui` again |
+
+A direct-PTY session has no pane to attach to, and says so.
+
+**`Enter` on a RECENT row resumes that conversation** instead: there is no pane to
+attach to, so the TUI creates a new claude session carrying the old transcript
+(`resumeSessionId`, exactly what the web UI's "Resume Conversation" list does), in
+the directory it originally ran in and under its old name, then attaches to it. It
+is claude-only, and a row with no working directory or no conversation id says why
+rather than resuming something else.
+
+`x` never bulk-kills: it kills one session, only after you retype its name, never a
+history row, and never the session the TUI itself is running in.
+
+## Over SSH, and on a phone
+
+The TUI is an ordinary terminal program with no local dependencies beyond tmux, so
+`ssh box` then `codeman tui` works exactly like running it locally. There is no
+separate remote mode.
+
+Below 72 columns (Termius, an iPhone in portrait) the preview pane is dropped and
+rows take two lines each: the same constraint the `sc` chooser was built around,
+now with a cursor, live states and the answer/prompt/kill verbs. The switch is
+width-driven at draw time, so unfolding a foldable or resizing a window re-lays out
+immediately; there is no mode flag to set.
+
+## Troubleshooting
+
+**"The Codeman server rejected these credentials."** The server has
+`CODEMAN_PASSWORD` set. Export `CODEMAN_PASSWORD` (and `CODEMAN_USERNAME` if it is
+not `admin`), or put them in the data dir's `.env` (`~/.codeman/.env`), which is
+where `codeman attach` already reads them from.
+
+**`server not running: attach only`** in a yellow banner. Nothing answered on the
+expected port, so the TUI fell back to enumerating tmux. You get names and attach;
+you do not get states, approvals or previews, because those only exist on the
+server. Start the server (`codeman web -d`, or `systemctl --user start codeman-web`)
+and the banner clears on its own: the TUI keeps re-probing.
+
+**It found the wrong server, or none.** Discovery is instance-scoped. A beta
+instance (`CODEMAN_INSTANCE=beta`) has its own data dir *and* its own tmux socket,
+so its TUI sees only its own sessions. Set `CODEMAN_PORT` or `CODEMAN_API_URL`
+explicitly when you run more than one.
+
+**"this terminal is already inside tmux on socket ..."** You are in a tmux session
+on a socket that is not Codeman's, so attaching would nest two multiplexers whose
+prefix keys collide. Detach from that tmux and run `codeman tui` from outside.
+
+**Boxes and glyphs render as garbage.** The TUI picks a glyph tier from the
+environment: no `TERM` (or `dumb`), or a non-UTF-8 locale, gets the ASCII set
+(`[!] [w] [*] [-]`, `+`/`-`/`|` frames). Force it either way with
+`CODEMAN_TUI_GLYPHS=ascii|unicode|nerd`.
+
+**Colors.** Standard `NO_COLOR` / `FORCE_COLOR` handling (chalk's, the same as the
+rest of the CLI). Under `NO_COLOR` the frame is cursor addressing and text only,
+and the preview's own colors are stripped too, so a session's output cannot repaint
+the dashboard.
+
+**It refuses to open at all**, saying it needs an interactive terminal. stdout or
+stdin is not a TTY. That is the guard: use `codeman tui --list`.

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

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

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

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

+- [Watching Agents Work](Watching-Agents-Work) - seeing what a loop is doing while it runs.

+
+## Dev setup
+
+```bash
+git clone https://github.com/Ark0N/Codeman.git
+cd Codeman
+npm install        # postinstall builds the vendored xterm addon bundles
+npm run dev        # http://localhost:3000
+```
+
+Requirements: Node 22+, tmux, and at least one agent CLI on your PATH.
+
+The frontend is plain JavaScript with no bundler in dev: edit a `.js` or `.css` file and
+reload. The exception is `index.html`, which is read once at server start, so markup changes
+need a restart.
+
+## Before you push
+
+CI runs all of these, so running them locally saves a round trip:
+
+```bash
+npm run typecheck
+npm run lint
+npm run format:check
+npm run check:frontend-syntax
+npm test -- test/<file>.test.ts   # one file, the normal way
+npm run test:ci                    # the full CI sweep
+```
+
+**Never run bare `npm test`.** The default configuration includes browser-driven Playwright
+suites that need a live server, Chromium, and environment-specific baselines; they hang or
+fail on a normal machine. `test:ci` is the honest "run everything".
+
+Tests are tmux-safe by design: under vitest the tmux layer becomes an in-memory mock, so
+tests cannot touch real sessions. If you add a test that binds a port, pick a unique one at
+3150 or above, and never 3000.
+
+## Finding your way around
+
+- Every source file opens with a `@fileoverview` block. Read it before the file; it is the
+  map.
+- [`CLAUDE.md`](https://github.com/Ark0N/Codeman/blob/master/CLAUDE.md) at the repo root is
+  the densest architecture primer there is. It is written for AI coding agents, but its
+  invariants apply identically to humans, and most review feedback traces back to something
+  already written there.
+- [`docs/architecture-invariants.md`](https://github.com/Ark0N/Codeman/blob/master/docs/architecture-invariants.md)
+  holds the deep mechanisms and the history behind each rule.
+
+## Good first contributions
+
+- **A theme skin.** A skin is four things kept in sync, and a static test checks the sync, so
+  if the test passes your skin works.
+- **A language.** The i18n module is dependency-free, English is canonical, and Simplified
+  Chinese is a complete example to copy.
+- **Docs.** If you got stuck and then figured it out, the sentence that would have unstuck
+  you is a pull request.
+- Anything labelled
+  [good first issue](https://github.com/Ark0N/Codeman/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22).
+
+Worth discussing first: new CLI backends, and real-device testing reports, especially
+mobile, which always find things emulation cannot.
+
+## PR expectations
+
+- One change per PR. Small and focused reviews fast; a grab bag stalls.
+- Target `master`.
+- **Keep your branch mergeable.** A PR with conflicts silently gets no CI runs at all, which
+  is a GitHub quirk rather than a Codeman one. Rebase when conflicts appear.
+- Include or update tests when you change behaviour.
+- Do not bump versions or edit the changelog; releases are handled after merge.
+- AI-assisted contributions are welcome, with one condition: understand what you are
+  submitting, and actually run it. "The model said it works" is not a test.
+
+## Fixing this wiki
+
+These pages are generated from
+[`docs/wiki/`](https://github.com/Ark0N/Codeman/tree/master/docs/wiki) in the main
+repository, and pushed here automatically when master changes.
+
+**Editing a page in the browser will be overwritten by the next sync.** Send a pull request
+against `docs/wiki/` instead. It is plain markdown, and a documentation PR is a genuinely
+useful contribution.
+
+Conventions for wiki pages:
+
+- Links between pages use the wiki form: `[Remote Access](Remote-Access)`, no `.md`.
+- Links into the repository are absolute `https://github.com/Ark0N/Codeman/blob/master/...`
+  URLs.
+- Images are referenced from the main repository over raw URLs rather than being copied into
+  the wiki.
+- Say what the default is, especially when it is off. Most of Codeman is opt-in.
+- Label Claude-only behaviour every time it appears. Six of the seven run modes are not
+  Claude.
+
+## Conduct
+
+Be kind, be direct, assume good faith. Report unacceptable behaviour privately via the
+contact in
+[SECURITY.md](https://github.com/Ark0N/Codeman/blob/master/.github/SECURITY.md).

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

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

+# Cron Jobs
+
+Saved, named jobs that start a session and send it a prompt on a schedule. Cron for agent
+sessions: *every weekday at 03:00, open a Claude session in `~/proj` and tell it to update
+dependencies and open a PR.*
+
+The ⏰ **Cron** header button is opt-in. Turn it on in
+**App Settings → Header & Panels**.
+
+## Creating a job
+
+1. Click **⏰ Cron**, then **+ New Job**.
+2. Give it a name, pick the agent type and working directory.
+3. Write the prompt, or point at a file containing it.
+4. Choose a schedule and leave **Enabled** on.
+5. **Save**. The job appears with its computed next run.
+
+**Run Now** fires it immediately without touching the schedule, which is the fastest way to
+find out whether the prompt does what you meant.
+
+## The fields
+
+| Field                    | Notes                                                                                       |
+| ------------------------ | ------------------------------------------------------------------------------------------- |
+| **Name**                 | Also used as the created session's name.                                                     |
+| **Agent type**           | Any run mode, including `shell`.                                                             |
+| **Working directory**    | Validated when you save **and** again when the job fires. Blocked system trees are refused.  |
+| **Launch command**       | Shell jobs only. Sent as the first line once the shell is up, before the prompt.             |
+| **Prompt**               | Inline text, or a path to a file read at fire time.                                          |
+| **Input mode**           | `typed` behaves like a human typing. `paste` writes directly.                                |
+| **Schedule**             | `once`, `interval`, `daily`, or `weekly`.                                                    |
+| **Enabled**              | Disabled jobs never fire on their own. **Run Now** still works.                              |
+| **Concurrency policy**   | What to do if sessions of the same type are already running.                                 |
+| **Auto-close previous**  | Recurring jobs only. Closes the session the previous run created. Default on.                |
+| **Notes**                | Free text for you.                                                                           |
+
+## Schedules
+
+All wall-clock times are in the **server's local timezone**, not your browser's. A job set
+for 03:00 fires at 03:00 where the server is.
+
+| Type       | Behaviour                                                                                          |
+| ---------- | -------------------------------------------------------------------------------------------------- |
+| `once`     | Fires at an absolute time, then disables itself. A job missed because the server was down still fires once on the next tick. |
+| `interval` | Every N minutes, from 1 minute to a year.                                                            |
+| `daily`    | At `HH:MM` every day. If today's time has passed, the next run is tomorrow.                          |
+| `weekly`   | At `HH:MM` on the weekdays you pick.                                                                 |
+
+Interval jobs re-anchor to when they actually fired, not to an ideal cadence, so a slow tick
+or a server restart shifts later runs slightly. That drift is accepted rather than corrected.
+
+## Prompts are single line
+
+This is the rule people trip over. Programmatic input into an agent session is single line
+everywhere in Codeman, because the terminal UIs these CLIs use treat a newline as submit. A
+multi-line prompt would be silently mangled, so it is **rejected** instead: the form refuses
+it, and a prompt file whose contents are multi-line fails the run with a clear message.
+
+For anything longer than a sentence, put the instructions in a file and make the prompt tell
+the agent to read it:
+
+```
+read TASKS.md and work through it
+```
+
+That is also easier to edit than a job field.
+
+### Prompt files
+
+Reading the prompt from a file at fire time is useful when the instructions change more
+often than the schedule. The path is confined to the job's working directory, symlinks are
+resolved before the check, sensitive trees are refused, and the file has to be a regular
+file under 1 MiB.
+
+If any of that fails, the run is recorded as failed and **no session is created**.
+
+## Concurrency
+
+Applies to scheduled runs only, never to **Run Now**:
+
+| Policy                          | Behaviour                                                                             |

+| `warn_only`                     | Always launch. The count of live same-type sessions is shown but does not block.        |
+| `skip_if_same_agent_running`    | Skip this fire if another live session of that mode exists.                             |
+
+The skip policy has the details you would want it to have:
+
+- Only **live** sessions block. A tab whose CLI already exited does not count.
+- Sessions the job created on its own previous runs never block it, otherwise a recurring
+  job would deadlock on itself after the first fire.
+- A skipped `once` job is not consumed. It stays armed and fires when the blocker goes away.
+- Consecutive skips are collapsed into one record per streak, so a perpetually skipped job
+  cannot bloat your state file.
+
+## Run history
+
+Every fire is recorded per job, with a status:
+
+| Status    | Meaning                                                              |
+| --------- | -------------------------------------------------------------------- |
+| `created` | The run started and a session was created.                            |
+| `skipped` | The concurrency policy blocked it. Not counted as a run.              |
+| `failed`  | The prompt could not be resolved, or the working directory was gone.  |
+
+The schedule is advanced **before** the session launches, so a slow start cannot cause the
+same job to re-trigger.
+
+## Cron versus the other autonomy features
+
+| Want                                                | Use                                                     |
+| --------------------------------------------------- | ------------------------------------------------------- |
+| Start work at a specific time                        | Cron                                                     |
+| Keep an existing session working                     | [Keeping Agents Running](Keeping-Agents-Running)         |
+| Drive one goal to completion across phases           | [Autonomous Loops](Autonomous-Loops)                     |
+
+There is also an older, deliberately separate `ScheduledRun` concept behind
+`/api/scheduled`: a run-now, duration-bounded loop with no recurrence and no saved jobs. The
+two systems never interact, and Cron is the one you want.
+
+## From the API

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

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

+# Driving Codeman From An Agent
+
+Everything the dashboard does is HTTP, so an agent can do it too. This page is for the case
+that makes Codeman interesting: **Claude Code running inside a Codeman session, spawning and
+supervising other sessions.**
+
+Two routes. Start with the skill.
+
+## The agent skill
+
+A Claude Code skill that teaches the agent the whole API, so you ask in plain English
+instead of pasting endpoint documentation into prompts.
+
+### Install it
+
+| How          | Command                                                     | Scope                                                       |
+| ------------ | ----------------------------------------------------------- | ----------------------------------------------------------- |
+| Skills CLI   | `npx skills add Ark0N/Codeman --skill codeman -g`            | Global, any skills-aware agent.                              |
+| Bundled CLI  | `codeman skill install`                                      | Global, at `~/.claude/skills/codeman`.                       |
+| Bundled CLI  | `codeman skill install --case <name>`                        | One case.                                                    |
+| Web UI       | **App Settings → Agents & CLIs → Claude → Agent Skill**      | Injects into each case when a Claude session is created. Off by default. |
+
+`codeman skill uninstall [--case <name>]` reverses the CLI installs, and never touches a
+`skills/codeman` you wrote yourself.
+
+### Then just ask
+
+| You say                                                                                 | What happens                                                                             |

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

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

+# HTTP API
+
+Codeman's HTTP and SSE API is a **stable contract**. Everything the dashboard does goes
+through it, so anything the dashboard can do, a script can do.
+
+This page is the orientation. The complete specification, including every wait semantic and
+the SSE catalogue, is
+[`docs/api-reference.md`](https://github.com/Ark0N/Codeman/blob/master/docs/api-reference.md).
+
+## What is stable
+
+Covered by semantic versioning: endpoint paths under `/api/v1`, the response envelope,
+`errorCode` values, and SSE event names.
+
+Not covered, and free to change in a patch release: on-disk state files, internal modules,
+and anything marked experimental. The full statement is in
+[Versioning](Versioning).
+
+`/api/v1/*` is a versioned alias of `/api/*`. Prefer the versioned form in anything you
+intend to keep.
+
+## The envelope
+
+```json
+{ "success": true, "data": { } }
+```
+
+```json
+{ "success": false, "error": "human readable", "errorCode": "NOT_FOUND" }
+```
+
+A few legacy GET handlers return bare bodies rather than the envelope, so a robust client
+reads `body.data ?? body`.
+
+Branch on `errorCode`, which is stable. The HTTP status is reliable too:
+
+| `errorCode`        | HTTP | Meaning                                          |
+| ------------------ | ---- | ------------------------------------------------ |
+| `INVALID_INPUT`    | 400  | Malformed request or failed validation.           |
+| `UNAUTHORIZED`     | 401  | Authentication required or failed.                |
+| `NOT_FOUND`        | 404  | No such resource.                                 |
+| `SESSION_BUSY`     | 409  | The session is busy.                              |
+| `CONFLICT`         | 409  | Conflicts with current state.                     |
+| `ALREADY_EXISTS`   | 409  | Resource already exists.                          |
+| `OPERATION_FAILED` | 422  | Well formed, could not be completed.              |
+| `RATE_LIMITED`     | 429  | Too many requests.                                |
+| `INTERNAL_ERROR`   | 500  | Unexpected server error.                          |
+
+New error codes are non-breaking. Removing or renaming one is a major change.
+
+**A `401` is the bare string `Unauthorized`, not the envelope.** Piping it into `jq` throws
+a parse error rather than showing the failure, so check the status first.
+
+## Authentication
+
+With no password set, and the default loopback bind, there is none. With `CODEMAN_PASSWORD`
+set, use HTTP Basic or the session cookie:
+
+```bash
+curl -s -u admin:"$CODEMAN_PASSWORD" "$API/api/sessions"
+```
+
+A **missing** `Origin` header is allowed, so curl and CLI tools work unchanged. A
+present-but-foreign origin is rejected by the CSRF guard. On an HTTPS install with the
+self-signed certificate, add `-k`.
+
+## Endpoint map
+
+Roughly 200 handlers across 24 route modules. By domain:
+
+| Domain              | Handlers | Covers                                              |
+| ------------------- | -------- | --------------------------------------------------- |
+| System              | 45       | Status, settings, search, digest, updates.           |
+| Sessions            | 34       | Create, input, terminal, wait, kill.                 |
+| Cases               | 29       | Create, link, clone, remote and docker cases.        |
+| Files               | 16       | Preview, edit, raw, attachments, path picker.        |
+| Orchestrator        | 10       | Plans and phases.                                     |
+| Ralph               | 9        | Loop control and configuration.                       |
+| Cron                | 9        | Jobs and run history.                                 |
+| Admin               | 8        | Multi-user administration.                            |
+| Plan                | 8        | Plan orchestration.                                   |
+| Respawn             | 7        | Respawn configuration and presets.                    |
+| Webviews            | 6        | Saved dashboards, plus the proxy.                     |
+| Mux                 | 5        | tmux operations.                                      |
+| Push                | 4        | Web push subscriptions.                               |
+| Read My Mind        | 4        | Intent profiles and prediction.                       |
+| Scheduled           | 4        | The legacy scheduled-run concept.                     |
+| Approvals           | 3        | The inbox and answering.                              |
+| Teams, me, search, hooks, clipboard, telemetry, voice, ws | 1-2 each | |
+
+Each route module documents its own endpoints in its file header.
+
+## Long-polling instead of polling
+
+Three calls block until something happens, so an agent driving Codeman from a shell can wait
+rather than spin:
+
+| Call                                      | Blocks until                                             |
+| ----------------------------------------- | -------------------------------------------------------- |
+| `GET /api/v1/sessions/:id/wait`           | One of a set of lifecycle signals fires.                  |
+| `GET /api/v1/sessions/:id/wait-output`    | A literal string appears in the session's output.         |
+| `POST /api/v1/sessions/:id/input` + `wait`| The input is delivered **and then** a signal fires.       |
+
+Three semantics that break callers who assume otherwise:
+
+1. **A timeout is `200`, not an error.** It answers with `wait.timedOut: true`. Loop over
+   short waits; a single long call gets cut by tunnels and proxies.
+2. **Send-and-wait is not a POST followed by a wait.** It registers the waiter *before*
+   writing, which closes the window where a separate wait sees the session still idle from
+   the previous turn and answers instantly about the wrong turn.
+3. **Signals are edge triggered with no history.** One that fires with no waiter registered
+   is unobservable afterwards. Fan-outs must register their waits as they dispatch.
+
+`wait-output` matches a **literal substring, never a regex.** That is deliberate: no regex
+means no catastrophic backtracking on attacker-influenced output.
+
+Only `claude` sessions emit `stop` and `blocked`, because those come from Claude Code hooks.
+Shell and external CLI sessions accept `idle`, `working`, and `exit`.
+
+## SSE
+
+`GET /api/events` is the live event stream. 155 event names, kept in sync between server and
+client with a test that fails on drift.
+
+The heartbeat is a **named** `sse:heartbeat` event rather than an SSE comment, because
+comments are invisible to `EventSource` by specification and a client could not observe
+them. That is what lets the browser detect a stream that has silently stopped delivering.
+
+```js
+const es = new EventSource('/api/events');
+es.addEventListener('session:created', (e) => console.log(JSON.parse(e.data)));
+```
+
+## Quick examples
+
+```bash
+API="${CODEMAN_API_URL:-http://localhost:3000}"
+
+curl -s "$API/api/status" | jq                     # whole-system snapshot
+curl -s "$API/api/sessions" | jq '.data[].name'    # live sessions
+curl -s "$API/api/sessions/unified" | jq           # live + historical, deduped
+curl -s "$API/api/subagents" | jq                  # background agents
+curl -s "$API/api/search?q=deploy" | jq            # cross-session search
+```
+
+## Limits
+
+| Limit                 | Default                                    |
+| --------------------- | ------------------------------------------ |
+| Max sessions          | 50                                          |
+| Max agent windows     | 500                                         |
+| Max SSE clients       | 100                                         |
+| Terminal buffer       | 32 MB per session                           |

+Codeman runs your coding agents on your own machine and puts them behind one dashboard you
+can open from any device. It spawns Claude Code, OpenCode, Codex, Antigravity, Gemini, or

+subscription limit resets, runs jobs on a schedule, and shows every background subagent
+live.

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

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

+# Installation
+
+Getting Codeman onto a machine, verifying it works, updating it, and removing it.
+
+## Requirements
+
+| Requirement      | Notes                                                                                                                                  |
+| ---------------- | -------------------------------------------------------------------------------------------------------------------------------------- |
+| **macOS or Linux** | Windows works through WSL2. See [Windows](#windows-wsl) below.                                                                        |
+| **Node.js 22+**  | The installer offers to install it if missing.                                                                                          |
+| **tmux**         | Not optional. Sessions live inside tmux, which is what makes them survive a server restart, a dropped connection, or a closed laptop.    |
+| **An agent CLI** | At least one of [Claude Code](https://docs.anthropic.com/en/docs/claude-code), [OpenCode](https://opencode.ai), [Codex](https://developers.openai.com/codex/cli), [Antigravity](https://antigravity.google), [Gemini CLI](https://github.com/google-gemini/gemini-cli), [Pi](https://pi.dev). Plain shell sessions need none. See [Agent CLIs](Agent-CLIs). |
+
+Codeman itself sends no telemetry and phones no home. The only network traffic is your
+browser to your server, and whatever the agent CLI you chose does on its own.
+
+## Route A: the installer (recommended)
+
+```bash
+curl -fsSL https://getcodeman.com/install | bash
+```
+
+This installs Node.js and tmux if they are missing, clones Codeman into `~/.codeman/app`,
+and builds it.
+
+What it asks you:
+
+1. **Permission for every system change.** Package installs and agent CLI downloads are
+   prompted individually. Nothing is installed silently.
+2. **How the dashboard should be reachable.** Three choices:
+   - **Tailscale** (recommended for phone access): keeps the loopback bind and walks you
+     through `tailscale serve`, including the tailnet HTTPS toggle, then verifies the result
+     end to end.
+   - **Your local network** (`0.0.0.0`): prompts for a password. Skipping the password takes
+     an explicit confirmation and ends on a loud warning.
+   - **This machine only** (`127.0.0.1`): the safest option, and the default for a bare
+     `codeman web` regardless of what you pick here.
+
+   Which one is preselected depends on what the installer finds. A fresh install defaults to
+   the local network, unless Tailscale is already connected, in which case it defaults to
+   Tailscale. An existing loopback install defaults to keeping loopback, or to Tailscale when
+   a serve mapping for Codeman is already there. A bare Enter never pulls in new software,
+   and a non-interactive run always keeps the safe loopback default.
+3. **What to do when it finishes.** Run in this terminal, install as a background service
+   that starts on boot, or do nothing yet.
+
+Re-running the same one-liner **updates an existing install in place**. Local changes in
+`~/.codeman/app` are stashed rather than discarded, a running service is restarted and
+verified, and your existing network binding is preserved. An interrupted first install
+resumes instead of restarting.
+
+Two other entry points exist:
+
+```bash
+install.sh update       # update only
+install.sh uninstall    # remove
+install.sh tailscale    # retrofit Tailscale access onto an existing install
+```
+
+**Automation and CI**: with no terminal attached, any step that would change the system
+aborts with instructions instead of running silently. Set `CODEMAN_NONINTERACTIVE=1` to
+approve those steps. `CODEMAN_TAILSCALE=1` preselects the Tailscale answer, and never
+installs Tailscale itself non-interactively.
+
+## Route B: npm
+
+```bash
+npm install -g aicodeman
+codeman web
+```
+
+The npm package is named `aicodeman`; the product is Codeman. Both `codeman` and
+`aicodeman` are installed as commands.
+
+The trade-off against Route A: no guided network setup, and the in-app self-updater does
+not apply. npm installs report as non-updatable in **App Settings → System → Updates**, and
+you update with `npm update -g aicodeman`.
+
+## Route C: git clone
+
+For contributing, or for running unreleased code.
+
+```bash
+git clone https://github.com/Ark0N/Codeman.git
+cd Codeman
+npm install            # postinstall builds the vendored xterm addon bundles
+npm run dev            # dev server on http://localhost:3000
+```
+
+For a production run from a clone:
+
+```bash
+npm run build
+npm run start
+```
+
+`npm run dev` runs TypeScript directly through `tsx` with no build step. The frontend is
+plain JavaScript served from `src/web/public/` with no bundler, so editing a `.js` or `.css`
+file and reloading the page is enough. The one exception is `index.html`, which is read once
+at server start, so markup changes need a restart.
+
+See [Contributing](Contributing) for the rest of the development loop.
+
+## Installing an agent CLI
+
+Codeman drives CLIs, it does not bundle them. Install at least one:
+
+| CLI             | Install                                                            | Notes                                                                      |
+| --------------- | ------------------------------------------------------------------ | -------------------------------------------------------------------------- |
+| **Claude Code** | `npm i -g @anthropic-ai/claude-code`                               | The primary target. Some Codeman features are Claude-only: see [Agent CLIs](Agent-CLIs). |
+| **OpenCode**    | See [opencode.ai](https://opencode.ai)                             |                                                                            |
+| **Codex**       | See [developers.openai.com/codex/cli](https://developers.openai.com/codex/cli) |                                                                |
+| **Antigravity** | See [antigravity.google](https://antigravity.google)               | Google's successor to the consumer Gemini CLI.                             |
+| **Gemini CLI**  | See [github.com/google-gemini/gemini-cli](https://github.com/google-gemini/gemini-cli) | Enterprise only since Google's June 2026 consumer cutover.  |
+| **Pi**          | See [pi.dev](https://pi.dev)                                       | No permission prompts and no sandbox by design. Read [Agent CLIs](Agent-CLIs) before using it on a repo you care about. |
+
+Log each CLI in once, by hand, before pointing Codeman at it. Codeman never collects or
+stores your CLI credentials.
+
+## Verify the install
+
+```bash
+codeman doctor          # checks Node, tmux, the agent CLIs, document converters
+codeman --version
+codeman web             # then open http://localhost:3000
+```
+
+`codeman doctor --json` gives machine-readable output, and `--category core` narrows it to
+the things a session cannot start without.
+
+If the dashboard loads and **+ New Session** opens, you are done. Continue to
+[Quick Start](Quick-Start).
+
+## Where things live
+
+| Path                    | What                                                                                             |
+| ----------------------- | ------------------------------------------------------------------------------------------------ |
+| `~/.codeman/app`        | The installed code (installer route only).                                                        |
+| `~/.codeman/`           | All state: `state.json`, settings, session history, push keys, TLS certs. See [Core Concepts](Core-Concepts). |
+| `~/codeman-cases/`      | Cases created from scratch. Linked cases stay wherever they already are.                          |
+| `~/.codeman/web.log`    | Log for a detached (`-d`) server.                                                                 |
+
+Everything is under your home directory, and nothing needs root.
+
+## Keeping it running
+
+A bare `codeman web` dies with the shell that started it. Two ways to outlive that:
+
+```bash
+codeman web -d          # detached; --status and --stop manage it
+codeman service install # systemd user unit or macOS LaunchAgent; survives reboots
+```
+
+Full detail, including logs and the self-updater, is in
+[Running As A Service](Running-As-A-Service).
+
+## Updating
+
+| Install route | How to update                                                     |
+| ------------- | ----------------------------------------------------------------- |
+| Installer     | Re-run the one-liner, or **App Settings → System → Updates** in the UI. |
+| npm           | `npm update -g aicodeman`                                          |
+| git clone     | `git pull && npm install && npm run build`, then restart.          |
+
+The in-app updater covers git-clone installs supervised by systemd or launchd. It restarts
+the process that is running it, so the actual work happens in a detached script and the
+browser polls across the restart. Progress appears in the UI.
+
+## Uninstalling
+
+```bash
+install.sh uninstall            # installer route
+npm uninstall -g aicodeman      # npm route
+```
+
+Neither removes `~/.codeman/` or `~/codeman-cases/`. Delete those by hand if you want the
+state and your case folders gone as well, and check `~/codeman-cases/` first: linked cases
+point at directories you already had, but cases created from scratch have their only copy
+there.
+
+Running tmux sessions are not killed by an uninstall. `tmux -L codeman kill-server` ends
+them.
+
+## Windows (WSL)
+
+```powershell
+wsl bash -c "curl -fsSL https://getcodeman.com/install | bash"
+```
+
+Codeman requires tmux, so Windows runs it inside
+[WSL2](https://learn.microsoft.com/en-us/windows/wsl/install). If you do not have WSL yet:
+run `wsl --install` in an admin PowerShell, reboot, open Ubuntu, and install your agent CLI
+*inside* WSL. `http://localhost:3000` then works from your Windows browser.
+
+Work inside the Linux filesystem (`~/project`), not `/mnt/c/...`. Filesystem watching and
+git are both dramatically slower across the Windows mount, and agents notice.
+
+## macOS notes
+
+**`Error: posix_spawnp failed.` on every session start.** node-pty publishes its macOS
+`spawn-helper` without the executable bit, and macOS launches every PTY through it. Codeman
+detects this and repairs it automatically on the first failure. If you hit it on a clone
+install and want to fix it by hand:
+
+```bash
+npm run fix:node-pty
+```
+
+This is a `chmod`, not a rebuild. Look in `prebuilds/darwin-<arch>/`, not
+`build/Release/`, which does not exist on macOS. Linux cannot reproduce this.
+
+**launchd and PATH.** A LaunchAgent gets `/usr/bin:/bin:/usr/sbin:/sbin`, which finds
+neither a Homebrew or nvm `node` nor `tmux` or `claude`. `codeman service install` bakes
+your current PATH into the unit for exactly this reason, so prefer it over a hand-written
+plist.
+
+## Gotchas
+
+- **`tmux: command not found` after a successful install.** The installer asks before
+  installing packages, and a declined prompt is a valid answer it remembers. Install tmux
+  and re-run.
+- **Port 3000 in use.** `codeman web --port 8080`, or set `CODEMAN_PORT`.
+- **Two Codemans on one machine.** The data directory and the tmux socket are both process
+  wide, so a second instance discovers and attaches the first one's live sessions. Give each
+  a distinct `CODEMAN_INSTANCE` before starting a second. See [Core Concepts](Core-Concepts).
+- **The dashboard is not reachable from your phone.** That is the default, not a fault. The
+  server binds `127.0.0.1`. See [Remote Access](Remote-Access).

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

+# Keyboard Shortcuts
+
+Every binding, and how to change them. `Ctrl` also accepts `Cmd` on macOS.
+
+Press `Ctrl+?` in the app for the same list in a floating overlay.
+
+## Sessions and tabs
+
+| Shortcut                        | Action                                                          |
+| ------------------------------- | --------------------------------------------------------------- |
+| `Ctrl+K` (also `Cmd+K`, `Alt+K`)| Find an open session or start a new one.                         |
+| `Ctrl+W`                        | Kill the active session.                                         |

+| `Alt+1` to `Alt+9`              | Switch to tab N. Physical keys, so macOS Option layouts work.    |
+| `Ctrl+Shift+{` / `Ctrl+Shift+}` | Move the active tab left / right.                                |
+| `Alt+B`                         | Collapse / expand the session sidebar, when that layout is on.    |
+
+## Terminal

+| Shortcut                | Action                                                          |
+| ----------------------- | --------------------------------------------------------------- |

+| `Shift+Enter`           | Insert a newline without sending.                                |

+| `Shift+Wheel`           | Scroll the local buffer, even where the wheel is forwarded to the CLI. |
+
+## Everything else
+
+| Shortcut       | Action                          |
+| -------------- | ------------------------------- |
+| `Ctrl+Shift+V` | Toggle voice input.              |
+| `Ctrl+?`       | Shortcut reference overlay.      |
+| `Escape`       | Close panels and modals.         |
+
+## Rebinding
+
+**App Settings → Shortcuts.** Bindings live in a registry with per-user overrides, so a
+rebind is stored as an override on top of the default rather than replacing the table.
+
+Two things are deliberately not rebindable:
+
+- **`Ctrl+C` smart copy.** The generic dispatch loop calls `preventDefault()` on every
+  shortcut it handles, and doing that to `Ctrl+C` would swallow the interrupt when nothing
+  is selected. It is handled separately for that reason.
+- **`Escape`**, which closes whatever is open.
+
+## Why some chords behave oddly
+
+The terminal sees keystrokes before the app does. Any chord the app claims has to also be
+swallowed at the terminal layer, or xterm writes the control byte into the session as well
+as triggering the action. If you rebind something to a chord the terminal cares about
+(`Ctrl+D`, say), expect the CLI to see it too.
+
+`Alt+1` through `Alt+9` are matched on **physical key position** rather than the character
+produced, so macOS Option layouts that produce `¡™£` still switch tabs.
+
+## On phones
+
+There is no physical keyboard, so the equivalents live in the keyboard accessory bar: `Esc`,
+`Ctrl` as a one-shot modifier, `Tab`, arrows, and quick actions. See
+[Mobile Guide](Mobile-Guide).

+is for.

+## Getting there
+

+   [Remote Access](Remote-Access).
+2. **Log in by QR.** Open the dashboard on your desktop and scan the code. No password
+   typing. Tokens are single use and rotate every 60 seconds.
+3. **Install it to your home screen.** On iOS this is mandatory for push notifications;
+   Safari does not deliver push to tabs. On Android it makes the app full screen.
+
+HTTPS matters for more than security here: microphone access and push notifications both
+require a secure context.

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

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

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

+# Quick Start
+
+From an installed Codeman to a working agent, in about five minutes. If you have not
+installed yet, start at [Installation](Installation).
+
+## 1. Start the server
+
+```bash
+codeman web
+```
+
+It prints a URL, `http://localhost:3000` by default. Open it.
+
+The server binds `127.0.0.1` only, so this URL works from the machine running it and
+nowhere else. That is deliberate: Codeman starts agents with permission prompts skipped by
+default, so anyone who can reach the dashboard can run code on this machine. Reaching it
+from your phone is a separate, deliberate step covered in [Remote Access](Remote-Access).
+
+To keep it alive after you close the terminal, use `codeman web -d` instead, or install it
+as a service. See [Running As A Service](Running-As-A-Service).
+
+## 2. Meet the welcome screen
+
+With no sessions running you get the welcome screen:
+
+- **Run buttons** for each agent CLI Codeman found on your PATH. If you expected one and it
+  is missing, its binary is not visible to the server; see [Agent CLIs](Agent-CLIs).
+- **A QR code**, if a password is set. Scanning it logs a phone in without typing anything.
+- **Resume Conversation**, a list of past sessions, including Claude conversations started
+  outside Codeman. Empty on a fresh install.
+- **Search**, across sessions, events, and files.
+
+You can click a Run button right now and get a working agent in your current case. The rest
+of this page is the deliberate version.
+
+## 3. Pick or create a case
+
+A **case** is a named working directory that Codeman remembers. Every session runs inside
+one. The case picker is in the bottom toolbar.
+
+To make a new one, click **+** next to the picker. The Add Case dialog has three tabs:
+
+| Tab               | Use it when                                                                                                        |
+| ----------------- | ------------------------------------------------------------------------------------------------------------------ |
+| **Create New**    | Starting a fresh project. Creates `~/codeman-cases/<name>` and scaffolds a `CLAUDE.md` into it.                     |
+| **Clone Repo**    | Working on an existing public repo. Paste the URL; Codeman preflights it as you type, offers the repo's real branches and tags, and fills in the case name. |
+| **Link Existing** | The code is already on disk. Point at the folder, with **Browse** if you would rather click than type.               |
+
+The gear next to the picker holds two per-case toggles: **Agent Teams** and
+**1M Opus Context**. Both are off by default and both are safe to ignore for now.
+
+**Create New** also has a checkbox for running the case inside a Docker container, and a
+**Remote** panel for running it over SSH on another machine. Those are
+[Docker Cases](Docker-Cases) and [Remote SSH Sessions](Remote-SSH-Sessions); skip them for
+your first session.
+
+## 4. Pick a run mode and hit Run
+
+The **Run** button starts an agent in the selected case. The arrow next to it picks which
+one:
+
+| Mode                 | What starts                                                    |
+| -------------------- | -------------------------------------------------------------- |
+| **Claude Code**      | The default, and the mode every Codeman feature supports.       |
+| **OpenCode**         |                                                                 |
+| **Codex**            | OpenAI's CLI.                                                   |
+| **Gemini**           | Enterprise only since Google's consumer cutover.                |
+| **Antigravity**      | Google's successor to the consumer Gemini CLI.                  |
+| **Pi**               | No permission prompts and no sandbox by design.                 |
+| **Terminal / Shell** | A plain shell, no agent. Also the **Run Shell** button.          |
+
+The dropdown also lists any saved dashboard URLs ([Web Tabs](Web-Tabs)) and your recent
+sessions. Those do not change the run mode: Run always means "start an agent".
+
+Click **Run**. A tab appears, and Codeman spawns the CLI on a real PTY inside a tmux
+session and streams it to your browser.
+
+The number spinner beside the button starts several sessions at once, up to 20. Useful for
+fanning the same case out across parallel workers; unnecessary for a first run.
+
+## 5. Talk to the agent
+
+Click into the terminal and type. It is a real terminal (xterm.js over a real PTY), so full
+TUIs render properly and everything the CLI supports works, slash commands included.
+
+| Key                          | Effect                                        |
+| ---------------------------- | --------------------------------------------- |
+| `Enter`                      | Send.                                          |
+| `Shift+Enter` / `Ctrl+Enter` | Newline without sending.                       |
+| `Ctrl+C`                     | Copy if text is selected, otherwise interrupt. |
+| `Ctrl+Shift+V`               | Voice input.                                   |
+
+You can also paste or drag an image straight into the session, and register external files
+as attachments. See [Working With Files](Working-With-Files) and
+[Input And Voice](Input-And-Voice).
+
+Input is delivered **exactly once**, even if your connection drops mid-prompt. A dropped
+link never loses a prompt and never sends it twice.
+
+## 6. Read the tab
+
+The tab tells you what the session is doing without opening it:
+
+| Signal                | Meaning                                                    |
+| --------------------- | ---------------------------------------------------------- |
+| Green dot             | Alive and idle.                                             |
+| Pulsing green dot     | Working on a turn.                                          |
+| Yellow, blinking      | Waiting for you to type something.                          |
+| Red, blinking         | A question or permission prompt is blocking the agent.      |
+
+Full tour in [The Dashboard](The-Dashboard). If you want a phone notification when an agent
+needs you, that is [Notifications And Approvals](Notifications-And-Approvals).
+
+## 7. Leave, and come back
+
+Close the browser tab. Close the laptop. The agent keeps running, because it lives in tmux
+and not in your browser.
+
+Reopen the dashboard and the session is still there with its scrollback intact. First load
+of a session pulls the full tmux scrollback, so you get the history, not just what arrived
+after you reconnected.
+
+This also survives restarting the Codeman server itself. What does not survive is killing
+the tmux server or rebooting the machine.
+
+## 8. Stop things
+
+| To do this                | Do that                                                             |
+| ------------------------- | ------------------------------------------------------------------- |
+| Interrupt the current turn | `Ctrl+C` with nothing selected, or the **Stop** button.            |
+| Close one session          | `Ctrl+W`, or the tab's close control.                              |
+| Stop the server, keep agents | `codeman web --stop`. The tmux sessions stay alive.              |
+| Stop everything            | `tmux -L codeman kill-server`.                                     |
+
+If you are working *inside* a Codeman-managed session (`echo $CODEMAN_MUX` prints `1`),
+never run `tmux kill-session` or `pkill claude` by hand. You will kill the session you are
+sitting in, along with its siblings.
+

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

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

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

+EOF
+launchctl bootstrap gui/$(id -u) ~/Library/LaunchAgents/com.codeman.web.plist

+
+Prefer `codeman service install` where you can. It handles the PATH problem for you.

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

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

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

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

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

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

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

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

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

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

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

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

+ * caller wraps the result in synchronized-output brackets (DECSET 2026) where
+ * the terminal supports it; that is an IO decision and stays out of here.
+ *
+ * Color is decided by the caller and passed in, never detected here: chalk's
+ * auto-detection is the right answer for the one-shot CLI (see `cli-style.ts`)
+ * but it would make a frame non-deterministic, and "same inputs, same string"
+ * is what makes this module testable. The palette below is the same semantic
+ * vocabulary chalk gives `cli-style` (ok green, warn yellow, err red, info
+ * cyan, muted gray, emph bold), written as raw SGR so the mapping is fixed.
+ *
+ * With `color: false` the frame contains no escape sequences at all beyond the
+ * cursor addressing that puts each line in place.

+ * @fileoverview Pure SSE wire parsing, event classification and reconnect math.
+ *
+ * Node has no `EventSource`, so the TUI reads `GET /api/events` as a raw stream
+ * and decodes the wire format here. Everything in this module is pure: bytes
+ * (as decoded strings) in, frames out. The socket, the timers and the backoff
+ * loop live in `tui-client.ts`.
+ *
+ * Three wire details this parser exists to get right:
+ *
+ * 1. **Frames split across chunk boundaries.** A TCP read can end anywhere,
+ *    including between the `\r` and the `\n` of a CRLF, so a lone trailing
+ *    `\r` is held back rather than treated as a line end.
+ * 2. **Comments are not frames.** The server appends a `:pppp…` padding line
+ *    after a frame while a Cloudflare tunnel is up (it flushes the proxy
+ *    buffer) and that line carries no blank line after it. Dispatch happens on
+ *    a blank line and on nothing else, so padding cannot split a frame.
+ * 3. **The keepalive is a NAMED event** (`sse:heartbeat`), because an SSE
+ *    comment is invisible to a browser `EventSource` by spec. We treat ANY
+ *    inbound bytes as liveness, comments included, which is why comments need
+ *    no representation in the returned frames.

+ *
+ * One definition, two consumers: the link provider matches its patterns over this
+ * text (`registerFilePathLinkProvider`) and touch selection measures words and
+ * whole lines with it (`_touchSelectionLogicalLine`). They MUST agree — a link that
+ * spans a wrap and a "Line" that stops at the screen edge is the same bug twice.
+ *
+ * Two kinds of continuation, and handling only the first is not enough:
+ *
+ *   1. **Soft wrap** — the emulator ran out of columns and flags the next row
+ *      `isWrapped`. It inserts nothing, so the row's text is joined verbatim.
+ *   2. **Hard wrap** — the program wrapped the text itself and emitted a real
+ *      newline, so nothing is flagged. A row that fills the last column is taken
+ *      as continuing into the next; that is the only trace a hard wrap leaves.
+ *
+ * ⚠️ A hard-wrapped continuation may carry the program's own INDENT, and joining
+ * that verbatim puts whitespace in the middle of the token being stitched. That is
+ * why an agent's numbered list —
+ *
+ *     1. https://github.com/users/someone/packages/container/p
+ *        ackage/thing
+ *
+ * — opened only `…/container/p`: the URL pattern stops at the space the indent
+ * contributed. So the leading whitespace of a HARD continuation is dropped, and
+ * `colStart` on that segment records how much, keeping the cell mapping exact. A
+ * soft continuation keeps its leading whitespace, since the terminal never adds
+ * any and it is therefore real content.
+ *
+ * ⚠️ Only the final row is trimmed. Continuation rows are read UNTRIMMED so each
+ * contributes exactly `cols` cells; trimming one would shift every later offset.
+ *
+ * The row span is bounded by `maxRows` (12 by default): this runs on every hover,
