 # aicodeman
 
+## 1.44.0
+
+### Minor Changes
+
+- ### Thanks
+  - @opticon454 for five PRs: config backups you can compare and restore (#661, ten review rounds), a File Viewer you can resize, expand and walk Back and Forward through (#659), GitHub Copilot's premium-request quota in the plan-usage chip (#662), a warning when llama.cpp's parallel slots leave too little context per request (#658, from #641), and a bare `npx vitest` that can no longer write into your real `~/.codeman` (#660, from #640).
+  - @JDProfresh for four PRs: the opt-in prompt-cache keep-alive (#666, step 2 of #554), Markdown links to file paths that open in the File Viewer (#665), a phone keyboard that stays up while you press accessory keys (#673), and a session swipe that no longer taps or scrolls the session you are leaving (#674), with the iPhone testing behind both phone fixes.
+  - @christianhaberl for four PRs: `CODEMAN_MAX_SESSIONS` (#668), tmux prefix keys that can no longer move a browser tab onto another session (#669), multi-line prompts that keep their line breaks (#670), and rediscovered tmux sessions that keep their own folder (#667). Also for the earlier #224, #225, #226 and the session sidebar (#307), whose commits carried an agent identity that GitHub credits to another account.
+  - @johoja12, a first-time contributor, for scroll batches that stay with the tab that made them, smoother trackpad scrolling and wheel scrolling in fullscreen Codex (#645), measured against the real CLI through five review rounds.
+  - @ludovicfourrage for touch scrolling in apps that track the mouse themselves (#664), and the careful write-up in #663.
+  - @aakhter for a default tab group per case (#676).
+
+  **Config backups (#661).** Codeman now keeps timestamped copies of the files that hold your setup: settings, CLI overrides, custom model endpoints, the webhook, linked cases and, in multi-user mode, the accounts. It takes one at startup and whenever one of them changes, into `~/.codeman/backups/config` by default. App Settings → System lets you pick the folder and the retention (keep N backups, drop ones older than N days), back up now, compare two backups or a backup with what is running (credentials are never shown, only whether they changed), and restore one. A restore first saves what it is about to replace, so it can be undone, and retention only ever deletes folders Codeman made and never the newest backup.
+
+  **Keep an idle Claude session's prompt cache warm (#666, opt-in).** Claude Code's prompt cache expires after an hour of quiet, and the next prompt then pays to re-read the whole conversation. Switch on **Keep the cache warm while idle** in a session's Respawn tab (or **Keep prompt caches warm** in App Settings → System → Automation for every new session) and Codeman sends a one-line keep-alive turn about five minutes before the cache would expire. It only does that when nothing else is going on: an empty prompt, no open dialog, nobody typing, no respawn, Ralph loop or waiting agent, no usage-limit pause. It stops on its own a while after your last prompt (**Keep warm for at most**, default 2 hours). A session started with it on also launches with Claude Code's own idle compaction off (Claude Code 2.1.290 or newer). The keep-alive raises no alert, push, webhook or Away-digest row, and the readout's Status line says what it is doing.
+
+  **A default tab group per case (#676).** Case settings has a **Default session group**: every new session for that case lands straight in that tab group, in the same write that creates it, so it never flashes in Ungrouped first. An explicit group on the create request and a spawned child following its parent still win. It is stored per user and survives a group rename.
+
+  **A File Viewer you can resize, with Back and Forward (#659).** Drag the corner grip to resize the window, or press Expand to fill the screen (remembered on this device). Following a link from one file to another builds a history that the ← and → buttons and Alt+← / Alt+→ walk through. Phones keep the full-screen viewer.
+
+  **Copilot's premium-request quota in the plan-usage chip (#662).** With the GitHub Copilot CLI installed and signed in, the header chip gains a Copilot row for the month's premium requests, with the counts and the reset date in the tooltip. Codeman reads it every 10 minutes from GitHub with the Copilot CLI's own sign-in token. It is on by default, like the Codex row, and turning Plan Usage Limits off in App Settings stops the request.
+
+  **More (or fewer) sessions with `CODEMAN_MAX_SESSIONS` (#668).** The cap of 50 concurrent sessions can be set at startup, from 1 to 462. A value that is not a positive integer falls back to 50, and the per-user cap in multi-user mode follows it unless `CODEMAN_MAX_SESSIONS_PER_USER` is set.
+
+  **Multi-line prompts keep their line breaks (#670).** A prompt sent through the API with `useMux` used to arrive as one welded line (`line oneline two`). Its lines now go into the pane as one bracketed paste, followed by the Enter that submits them together. The senders that run unattended (cron, respawn's update and kickstart prompts, the auto-compact focus, `codeman agent send`, the TUI and the skill's `sendwait`) stay single-line and join lines with a space, because the submit check cannot yet recognise a multi-line paste in the composer.
+
+  **A warning for llama.cpp slots that split the context too thin (#658).** A custom llama.cpp model that runs several parallel slots splits its context between them, and four 40K-token Claude requests against a 4-slot, 131K pool all failed with "Context size has been exceeded". Discovery now records each model's slot count, and a Claude launch warns when one slot gets less than 40K tokens, naming the fix (`--parallel 1`, or a context large enough for every slot).
+
+  **Fixes.**
+  - **tmux prefix keys stay out of browser tabs (#669).** Ctrl+B then `)`, `(`, `s` or `w` in a tab switched its tmux client to another session while the tab kept the first one's name. Codeman's tmux socket now keeps only Ctrl+B Ctrl+B (send-prefix) in its prefix table, set at session start and at boot. This also means `Ctrl+B d` no longer detaches a terminal attached to that socket: `codeman tui` and `scripts/tmux-manager.sh` detach with F1.
+  - **Scrolling stays with its tab, and fullscreen Codex scrolls (#645).** A queued wheel batch can no longer land in a tab you switched to, trackpads keep their fractional travel instead of dropping it, the first wheel report of a tab visit goes out at once, and Codex gets wheel reports while it has mouse tracking on (measured on Codex 0.163.0, where an approval prompt's selection is unaffected).
+  - **Touch scrolling in apps that track the mouse (#664).** A finger drag and its fling now scroll a program in the pane that asked for SGR mouse reports (a TUI in a shell tab, for example) instead of scrolling a local buffer that cannot show it. Other mouse encodings are left alone.
+  - **A session swipe only switches sessions (#674).** A sideways swipe on the terminal no longer also opens a link, taps a CLI menu or toggles the keyboard on the session you are leaving. A deliberate swipe gets 500 ms instead of 300, a selection or a second finger pauses it, and a scroll that starts on a sideways thumb arc still scrolls.
+  - **The phone keyboard stays up (#673).** Arrow, Tab, Esc and the other accessory keys that act on the terminal no longer blur it for a moment, so the toolbar stops bouncing on every tap.
+  - **Markdown links to files open in the File Viewer (#665).** A link like Codex's `[label](/abs/path.json)` in the response viewer now opens the file instead of a same-origin 404 tab, and its label keeps the prose font.
+  - **Rediscovered sessions keep their folder (#667).** A tmux session Codeman finds again on its socket (after `mux-sessions.json` was lost) now gets the directory tmux reports for its pane instead of the server's own, so a respawn goes back to the right project.
+  - **Web tabs send POST bodies to dashboards that read Content-Length.** Codeman's web-tab proxy now relays the browser's Content-Length, so a dashboard built on Python's `http.server` or a small Go or C server no longer sees an empty body on every POST made through a web tab.
+
+  **Fixes applied while landing.** A restore that fails partway now says which files it restored, which it could not and where the pre-restore copy is, re-reads what was written and refills the Settings form; backup passes list the manifests once, and a pre-restore copy equal to the newest backup is not made twice (#661). A failed keep-alive write is retried before the expiry instead of never, an unreadable `settings.json` is logged once instead of every minute for every session, the keep-alive's own hooks stay out of the run summary, and saving App Settings re-plans keep-alives only when their settings changed (#666). The Copilot quota read checks the setting and the sign-in token before it ever probes for the CLI, so a machine without Copilot runs no login shell every 10 minutes, and drops a header the Copilot CLI itself does not send (#662). The prefix-table reset still binds send-prefix on an empty table and no longer reruns on every session for a prefix tmux lists escaped (#669). Claude worktree sessions follow the case's default group like every other CLI's (#676). The remote-history PATH change that rode along in #645 was left for its own PR. Smaller touches: the Expand button keeps its label while pressed and Alt+← / Alt+→ are listed in the shortcut overlay and help (#659); the scroll log names xterm's mouse encoding (#664); the response-viewer link test covers `?query` and folder links (#665).
+
+  **Docs and tests.** A bare `npx vitest run` from the repo now uses the isolated CI config instead of running without the setup file, the helpers that delete test folders refuse to run outside a sandboxed HOME, and the temp-HOME teardown is bounded so a stuck writer cannot time the hook out (#660). New sections and lines for config backups, the keep-alive and the Copilot quota in the architecture notes and `CLAUDE.md`, a test that a deleted pane directory is never adopted (#667), the codeman skill preamble re-stamped 1.44.0, and browser tests for the touch-scroll and swipe fixes.
+
+## 1.43.0
+
+### Minor Changes
+
+- ### Thanks
+  - @opticon454 for five PRs: GitHub Copilot CLI as a run mode (#592), an Antigravity tab that shows when it is working (#648, reported in #639), a WS pill that no longer flickers on every paste (#647, reported in #638), custom-folder cases anywhere below a broad cases folder (#567, reported in #637), and the opt-in "Pin tab names on the CLI" setting (#646). Also for filing #637 to #641 with the cause already worked out, and for measuring Copilot and `agy` live instead of guessing.
+  - @JDProfresh for four follow-ups to the document uploads in #621: a mixed pick, drop or paste that says how many files it skipped (#651), a text upload refused as "not UTF-8" instead of a type mismatch (#652), a parity test that keeps the browser's copies of the document list honest (#653), and link taps on a phone that land on the right row after a tab switch (#654).
+  - @irisitymichaelgrundberg for clickable `.diff` and `.patch` paths (#644).
+
+  **Security notices for the CLIs you run.** Codeman can now warn you about a security incident in an agent CLI it runs, and it does so only on machines where that CLI is installed. After an update the warning sits inside the "Codeman updated" note, with a button to the vendor's own notice next to **See what's new**; on a new install, or if you missed it, it comes as a card of its own. It stays until you close it or open the link, and expires on its own. The first one is about OpenCode: on 17 October OpenCode reported unauthorized access to a legacy system, and provider API keys (OpenAI, Anthropic and others) saved in some OpenCode Console workspaces may have been exposed. If OpenCode emailed you about it, revoke and replace those keys and check their recent usage. If you got no email, OpenCode says you were not affected.
+
+  **GitHub Copilot CLI is a run mode (#592).** Install `copilot` (`npm install -g @github/copilot`) and it appears in the Run menu, on the welcome screen, in cron and in CLI management. It runs in tmux like the other agent CLIs, shows working and idle and the model it reads off its own footer, takes the usual launch options (`copilotConfig`: model, resume, continue, and `allowAll`, which is clamped off for non-granted multi-user owners), works with Custom Model Endpoints through Copilot's BYOK variables, joins MCP sync, and works with `codeman agent spawn`, `send` and `read`. A plain drag selects text, so Auto Copy works, while the wheel and phone swipes scroll its transcript. Copilot's folder-trust dialog still needs one Enter the first time a folder is used.
+
+  **Pin tab names on the CLI (#646, optional).** A new App Settings switch, off by default, launches every Claude session with `--name <tab name>`, not only the ones you renamed, so Claude Code's prompt-box label, `/resume` entry and remote session list match your tabs. The cost, which the setting spells out: Claude stops generating its own titles for those sessions, and a rename in Codeman holds only until the next turn. It applies from the next session start or respawn.
+
+  **Antigravity tabs show when they are working (#648).** An `agy` turn now marks its tab working and a finished turn reads as idle again. A shell command waiting for your approval keeps showing as working until you answer it.
+
+  **Fixes.**
+  - **Custom-folder cases below the cases folder (#567).** Create New with a custom folder refused every folder anywhere below the cases folder. Now only the cases folder itself and its direct children are refused, since those are the only ones listed as local cases, so a broad `CODEMAN_CASES_PATH` such as `/mnt/user/Scripts` no longer blocks the whole tree. The refusal now says which of the two it hit.
+  - **A steady WS pill (#647).** The ` · NB queued` suffix appears only once a backlog has lasted over a second, instead of flashing on every paste, IME commit or fast burst.
+  - **Clickable diff and patch files (#644).** A `.diff` or `.patch` path is now a link in the terminal and the response viewer, so an agent's review diff opens in one click.
+  - **Mixed uploads say what they skipped (#651).** A pick, drop or paste with some unsupported files attaches the rest and says how many it skipped; the Compose and paste-dialog pickers now report an unsupported pick instead of doing nothing.
+  - **"Not UTF-8" for refused text uploads (#652).** A text file that fails the UTF-8 check is told it is not UTF-8 (or UTF-16, when it starts with that byte order mark) and to save it as UTF-8, instead of reading like a corrupt file.
+  - **Link taps on a phone after a tab switch (#654).** With the view parked above the bottom, a URL typed into the prompt no longer opens on tap, and a link in the scrollback opens on its own row.
+
+  **Fixes applied while landing.** The Copilot run mode clamps every `COPILOT_*` variable that bypasses approval, runs code or moves the token for non-granted multi-user owners, keeps a divider row inside an answer as part of what `codeman agent read` returns, and its Docker docs no longer promise a token you cannot set there (#592). Antigravity's working line only matches at the start of a row, so an answer that quotes the spinner no longer holds the tab busy (#648). The custom-folder refusal names the cases folder itself and a direct child separately (#567). The WS pill reads its queue once per update (#647). The "Pin tab names" setting is translated for zh-CN and listed in the Settings Reference (#646). JSON files the page fetches at runtime (the update note, the security notices) are now served `no-cache` instead of cached for a year, so a later notice always reaches a browser that already has the old copy.
+
+  **Docs and tests.** New route tests for nested custom-folder cases and for Copilot's screen-read answers, a wrapped-composer touch test, stricter upload parity checks, and docs that move Antigravity and Copilot into the screen-checked idle group.
+
+## 1.42.0
+
+### Minor Changes
+
+- 1238316: ### Thanks
+  - @JDProfresh for five PRs: prompt uploads that take documents (#621, from the plan in #553), a video Codeman cannot take refused before it uploads (#622), a prompt-cache readout kept to the CLIs that report one and a statusline report with many cache-miss causes no longer thrown away (#623), and two fixes for Claude's workspace trust dialog in a brand-new folder: idle waits that hold until the dialog is answered (#634) and a dialog that gets answered every time (#635).
+  - @Randalix for Codex prompts that really get submitted, sent as one bracketed paste and a separate Enter (#628), and for the careful measurements in #627 that found the cause.
+  - @ludovicfourrage, a first-time contributor, for reporting (#629) and fixing (#632) the nested tmux status bar colour that leaked into live output after a history reload.
+  - @opticon454 for three PRs: a one-time "what's new" note after each update (#618), Previous and Next Session as rebindable shortcuts that refuse a chord another action already uses (#617), and a DeepSeek install from CLI management that ends with a DeepSeek you can run (#616).
+
+  **Git worktrees for a case (#625).** Give every agent on a repository its own checkout. Pick a case whose folder is a git repository, choose **Git worktrees…** in the case picker (**Worktrees** on the phone's case sheet), type a name and pick the CLI: Codeman creates `<case>/.claude/worktrees/<name>` on a new branch `worktree-<name>` and opens a session there, in a tab named after the worktree. **Open** starts another session in a worktree you already have. Removing one runs plain `git worktree remove`, never `--force`, so uncommitted work stays where it is, and Close Session can kill the session and remove its worktree in one go. The layout is the one Claude Code's own `claude --worktree` uses, so each sees the other's worktrees. To keep the main checkout clean, Codeman lists the worktrees folder and the files it writes for sessions in the repository's local `.git/info/exclude`; your `.gitignore` is never touched.
+
+  **Codex sessions turn red when Codex asks you something (#624).** Codex's command and edit approvals, its question dialogs and the trust prompt on a new repository are read straight off the screen and raised the way a Claude permission prompt is: red tab, desktop notification, push, webhook, the phone's NEEDS YOU row and an Approvals Inbox card that tells you to answer in the terminal. An agent driving a codex worker can now wait for that with `until=blocked`.
+
+  **Prompt uploads take documents (#621).** Attach, drop or paste a PDF, a Word, PowerPoint or Excel file, a zip, or a text file (txt, md, csv, tsv, json, log, yaml, xml) and its path lands on your prompt, ready to send, like a photo or a video does. Every file is checked against its actual bytes on the way in, so a program renamed to `.pdf` is refused, and text files must be UTF-8. The saved name keeps a readable part of the original: `Q3 report.pdf` is saved as `paste-...-Q3-report.pdf`. The button in the Compose and paste dialogs now says Attach.
+
+  **Previous and Next Session are rebindable (#617).** Previous Session (Alt/Option+[) and the alternate Next Session (Alt/Option+]) are now ordinary rows in App Settings > Shortcuts, so you can rebind or switch them off like everything else. Capturing a chord another action already uses is refused with a message naming that action (Alt+1 to 9, Ctrl/Shift+Enter and Ctrl/Cmd+V stay reserved), and re-enabling or resetting a shortcut runs the same check. A chord you rebound no longer also types into the terminal: a rebind to Alt+J used to switch tabs and send ESC j to the session too. Built-in defaults like Ctrl+L still reach the CLI.
+
+  **A note after each update (#618).** The first time a browser loads a newer Codeman, a toast lists that release's headline changes, with a **See what's new** button that opens the full release notes. It shows once per version, and a browser that has never opened Codeman before just records the version and stays quiet, so the first note you will see is the one for the release after this one. The headlines are taken from the changelog when the release is cut.
+
+  **Multi-user mode: only admins change server-wide settings.** In multi-user mode any signed-in regular user could rewrite the server's settings (feature switches, run mode, case order, the default model for cron and the orchestrator, the app config), start a self-update, rotate the tunnel QR code, clear stale session state, and sign every user out with Revoke All, admins included. They could also read the Deepgram API key an admin saved. Those writes and operations now answer 403 to a regular user, Revoke All signs them out of their own logins only, and their settings read leaves out the admin's key and case names. In the browser a regular user's per-device settings still save, a change to a server-wide setting shows one notice that only an admin can change it, instead of pretending it was saved, and their own run mode and respawn presets are kept on their device. Single-user mode is unchanged.
+
+  **Fixes.**
+  - **Codex submits long prompts (#628).** Prompts sent through the API, `codeman agent send`, the MCP server, cron or the agent skill go into the pane as one bracketed paste followed by a separate Enter, so Codex no longer leaves them sitting unsent in its composer. A single character (a menu answer like `3` or `y`) is still typed, so numbered dialogs keep picking the option you sent, and a trailing `;` survives, so `find . -exec rm {} \;` arrives whole.
+  - **New Claude sessions in an untrusted folder (#634, #635).** An agent waiting for a fresh session to go idle no longer gets its answer while the workspace trust dialog is still up, so its first prompt can no longer press Enter on the highlighted "No, exit" and kill the session it just started. And the dialog is now answered every time: a screen read that came too soon after the previous one used to be dropped, which now and then left a new session sitting on the dialog. Deleting a session while the dialog is up also stops Codeman reading its dead pane for seconds afterwards.
+  - **Nested tmux colours after a history reload (#632).** Opening a remote or Docker case, or a shell running tmux inside it, no longer hands the nested tmux status bar's green background to whatever the agent prints next.
+  - **The codeman skill with arguments (#642).** The skill works again when Claude Code loads it with arguments ("use codeman to start 5 claude workers"). Claude Code swaps a skill's `$1` and `$2` for words of your request, which broke the pasted helpers; they now use `${1}` and `${2}`, and a cached copy written by the broken version is rewritten on the next run.
+  - **DeepSeek installs ready to run (#616).** Installing the terminal profile finds the `pnpm` next to `dsh` even when the server's own PATH lacks `~/.local/bin`, and the DeepSeek install command adds `pnpm` when the machine has none.
+  - **Unsupported videos refused up front (#622).** An Android `.3gp` or an `.mkv` gets "Unsupported file type" right away, instead of uploading up to a gigabyte and failing at the end.
+  - **Statusline reports (#623).** The prompt-cache readout is stored only for CLIs whose statusline reports one (Claude today), like the model badge, and a Claude report with more than 20 cache-miss causes keeps the first 20 instead of being refused, which used to blank the footer and the plan-usage chip.
+
+  **Fixes applied while landing.** Removing a worktree that is, sits inside or holds a Docker case's workspace is refused before git runs; it would have deleted the folder a container still mounts (#625). Codex's trust prompt also reads as blocked in the variant reached through its "Update available" screen, which ends in "esc back" (#624). The DeepSeek install only adds `pnpm` when none is on PATH, so a machine with a corepack `pnpm` keeps it instead of the whole install failing (#616). Three statements in the upload docs were corrected: only a local agent and a Docker case share the uploads folder (remote sessions are refused), GIFs keep their frames instead of being re-encoded, and a developer note no longer names a release that never shipped (#621). The update note skips the Thanks list and group labels like "Fixes.", still works for a release with no headlines, and is translated for zh-CN (#618).
+
+  **Docs.** The README and its Chinese translation caught up with 1.41.0 and 1.41.1 and show a sharper hero GIF, the Codeman Skill got a wiki page and two GIFs linked from both READMEs, CLAUDE.md was split into the root file, `src/web/CLAUDE.md` and `docs/releasing.md`, the release steps now include the MCP registry publish, and a new note says where video and GIF masters live (not on GitHub).

-> **Repo root is kept short on purpose** (the README sits below the file listing on GitHub). Config lives in `config/` (`eslint.config.js`, `knip.json`, the vitest configs), Prettier's config is the `"prettier"` key in `package.json`, and `SECURITY.md` is under `.github/`. Root-only files are the ones tools genuinely require there: `CLAUDE.md` + `AGENTS.md` (loaded from the root by Claude Code / Codex), `CHANGELOG.md` (changesets writes it next to `package.json`), `tsconfig.json`, `.editorconfig`, `.nvmrc`/`.npmrc`, `.prettierignore` (resolved relative to cwd), `LICENSE` (GitHub detection), `.dockerignore` (the build context is the repo root, so Docker resolves it there and nowhere else) and `install.sh` (its raw URL is the published install one-liner). `.claude-plugin/marketplace.json` is root-only for the same reason: `/plugin marketplace add Ark0N/Codeman` reads it from the repo root and nowhere else, which makes the repo its own plugin marketplace. The one plugin it lists is `plugins/codeman/` (manifest + README + a MIRROR of `skills/codeman/`), and ⚠️ the plugin is a small separate directory on purpose: `claude plugin install` copies the plugin root into its cache, and a plugin root that carries a `package.json` gets an **npm install** at install time (measured with the repo root as plugin root: 832 MB, 511 packages and this repo's postinstall on every installer's machine), while a symlink to `skills/codeman` would dangle in the copy. `skills/codeman/` stays the single source; `scripts/sync-plugin.mjs` mirrors it and writes `package.json`'s version into both manifests inside `version-packages`, and `test/plugin-manifest.test.ts` pins the byte-identity, the versions, the absence of a `package.json` in the plugin root and that no other component (`commands/`, `agents/`, `hooks/`, `.mcp.json`, `settings.json`) rides along. `npm run check:plugin` runs that drift check plus both strict validations with EXPLICIT paths (`plugins/codeman`, `.claude-plugin/marketplace.json`): a bare `.` argument copied out of prose reads as a full stop and gets dropped, which surfaces as `missing required argument 'path'`.

Config lives in `config/` (`eslint.config.js`, `knip.json`, the vitest configs), Prettier's config is the `"prettier"` key in `package.json`, and `SECURITY.md` is under `.github/`. Root-only files are the ones tools genuinely require there: `CLAUDE.md` + `AGENTS.md` (loaded from the root by Claude Code / Codex), `CHANGELOG.md` (changesets writes it next to `package.json`), `tsconfig.json`, `.editorconfig`, `.nvmrc`/`.npmrc`, `.prettierignore` (resolved relative to cwd), `vitest.config.ts` (a one-line re-export of `config/vitest.ci.config.ts`: vitest finds its config by walking up from cwd, so without it a bare `npx vitest` ran with no setup file and wrote into the real `~/.codeman`, #640), `LICENSE` (GitHub detection), `.dockerignore` (the build context is the repo root, so Docker resolves it there and nowhere else) and `install.sh` (its raw URL is the published install one-liner). `.claude-plugin/marketplace.json` is root-only for the same reason: `/plugin marketplace add Ark0N/Codeman` reads it from the repo root and nowhere else, which makes the repo its own plugin marketplace. The one plugin it lists is `plugins/codeman/` (manifest + README + a MIRROR of `skills/codeman/`), and ⚠️ the plugin is a small separate directory on purpose: `claude plugin install` copies the plugin root into its cache, and a plugin root that carries a `package.json` gets an **npm install** at install time (measured with the repo root as plugin root: 832 MB, 511 packages and this repo's postinstall on every installer's machine), while a symlink to `skills/codeman` would dangle in the copy. `skills/codeman/` stays the single source; `scripts/sync-plugin.mjs` mirrors it and writes `package.json`'s version into both manifests inside `version-packages`, and `test/plugin-manifest.test.ts` pins the byte-identity, the versions, the absence of a `package.json` in the plugin root and that no other component (`commands/`, `agents/`, `hooks/`, `.mcp.json`, `settings.json`) rides along. `npm run check:plugin` runs that drift check plus both strict validations with EXPLICIT paths (`plugins/codeman`, `.claude-plugin/marketplace.json`): a bare `.` argument copied out of prose reads as a full stop and gets dropped, which surfaces as `missing required argument 'path'`. Needs the `claude` CLI, so it is a local check, not a CI step. Don't relocate those.

 ## COM Shorthand (Deployment)
 
 Uses [Semantic Versioning](https://semver.org/) (`MAJOR.MINOR.PATCH`) via `@changesets/cli`. What SemVer actually covers (the CLI, documented env vars, **and the HTTP/SSE API under `/api/v1`**: endpoint paths, response envelope, `errorCode` values and SSE event names are public/stable; on-disk state, internal TS modules, and experimental features are internal/unstable) is defined in `docs/versioning-policy.md`. Third-party integration surfaces are documented in `docs/extending-codeman.md`. Security reporting + known limitations live in `.github/SECURITY.md`.
 
-When user says "COM":
+When the user says **COM** (`COM` = patch, `COM minor`, `COM major`): **Read [`docs/releasing.md`](docs/releasing.md) and follow every step in order**; never improvise a release from memory. It covers the changeset, `npm run version-packages`, the `**Version**` line below, the branch check and explicit-path commit, deploy, the getcodeman.com badge, watching BOTH CI workflows, the MCP registry publish, and the Discussions announcement.
 
-1. **Determine bump type**: `COM` = patch (default), `COM minor` = minor, `COM major` = major
-2. **Create a changeset file** (no interactive prompts). Write a `.md` file in `.changeset/` with a random filename:
-
-   ```bash
-   cat > .changeset/$(openssl rand -hex 4).md << 'CHANGESET'
-   ---
-   "aicodeman": patch
-   ---
-
-   Detailed description of ALL changes since last release (not just the most recent commit — review full git log since last version tag)
-   CHANGESET
-   ```
-
-   Replace `patch` with `minor` or `major` as needed. Include `"xterm-zerolag-input": patch` on a separate line if that package changed too.
-
-3. **Consume the changeset**: `npm run version-packages` (auto-bumps `package.json` files, updates `CHANGELOG.md`, runs `npm install --package-lock-only`, and verifies lockfile sync via `scripts/check-lockfile-sync.mjs` — all in one command; never hand-edit `CHANGELOG.md` or `package-lock.json` versions)
-4. **Sync CLAUDE.md version**: Update the `**Version**` line below to match the new version from `package.json`
-5. **Commit and deploy**: verify the branch first (`git branch --show-current`), then stage EXPLICIT paths — never `git add -A`, which has swept another session's WIP into a release. `git status --short` and account for every line before committing:
-   `git add <paths> && git commit -m "chore: version packages" && git push && npm run build && systemctl --user restart codeman-web`
-6. **Refresh the getcodeman.com version badge**: the landing page's status bar carries the release version (`v<x.y.z> · getcodeman.com · MIT`), so it goes stale on every release if nobody bumps it. The site source and its deploy script are maintained outside this repository, on the maintainer's machine only; follow the local site handbook there, which also covers the numbers strip and `sitemap.xml` refresh that belong in the same pass. Poll production (`curl -s https://getcodeman.com/ | grep v<x.y.z>`) before calling it done, since the edge lags a deploy by up to a minute. Not applicable to contributor clones — skip it and say so.
-7. **Wait for CI**: after `git push`, TWO workflows fire per master push — `CI` and `Release` (the npm publish + GitHub release). List both runs for the pushed commit with `gh run list --commit $(git rev-parse HEAD) --json databaseId,workflowName` and watch EACH with `gh run watch <id> --exit-status`. Confirm both pass before considering the release done (`gh run list -L 1` returns only one of the two).
-
-8. **Announce it in Discussions**: every release gets a post in the [Announcements](https://github.com/Ark0N/Codeman/discussions/categories/announcements) category, shaped like #418 and #302: the short version first (one bold lead-in per theme, features before fixes, what it does for the user rather than how it works), contributor @-mentions inline where their work is described (a mention notifies them, and a contributor reposting is the cheapest reach this project has), a link to the release, and the Thanks names at the end. Casual first-person voice, no em-dashes, humanizer pass when the skill is available. A same-day follow-on patch (1.28.1 after 1.28.0) is folded into the previous post as an edit, never a second thread. Post it with `gh api graphql -F body=@<file> -f title='Codeman <x.y.z>: <hook>' -f repo=R_kgDOQ-SMDg -f cat=DIC_kwDOQ-SMDs4DCHZE -f query='mutation($repo:ID!,$cat:ID!,$title:String!,$body:String!){createDiscussion(input:{repositoryId:$repo,categoryId:$cat,title:$title,body:$body}){discussion{number url}}}'` (the repo's node id and its Announcements category id; `pinDiscussion` does not exist in the API, so pinning stays a click in the UI). This step exists because announcements stopped at 1.18 (#302) while ten releases shipped with nobody notified; #418 is the backfill covering 1.19.0 to 1.28.1, and release notes only count as content once they reach a surface people are subscribed to.

-CI runs `npm run check:lockfile` on every push/PR, so lockfile drift fails the build even if the `version-packages` script is bypassed.

 ## Common Gotchas
 
-- **Single-line prompts only** — `writeViaMux()` sends text+Enter separately; multi-line breaks Ink. ⚠️ **Input must END with `\r` or Enter is never sent**: `sendInput()` only issues `send-keys Enter` when the payload contains a carriage return, a `\r`-less `POST /api/sessions/:id/input` still succeeds (send-and-wait even reports `delivered:true`) while the text sits unsubmitted on the composer, and any `wait` burns its whole timeout on a turn that never started. Embedded newlines are stripped, not rejected, so `"echo A\necho B\r"` runs the joined `echo Aecho B`. ⚠️ **Claude Code 2.1.277+ ignores Enter for the first 30-50 s after the composer paints** while still taking the typed text (measured 2026-09-19: an Enter at 28 s stranded the prompt, one at 51 s submitted it), so text+`\r` sent at readiness sits unsent with `0 tokens` and a `wait` burns its timeout. So the SERVER verifies every programmatic write that carried a `\r`: `SubmitVerifier` (`session-submit-verifier.ts`, armed from `writeViaMux`) reads the pane on a 2 s to 60 s schedule and re-sends Enter only while the LAST composer line (the CLI's own `promptGlyph`) verifiably still holds the head of what was sent; an empty composer, other text, or no composer line at all (a shell, a direct-PTY session) ends it, and a newer write replaces the schedule. The skill's `sendwait` keeps its own copy of the loop (`_composer_text` in `skills/codeman/preamble.sh`) for servers that predate this. The `shift+tab` footer only means the composer painted, never that Enter is accepted. ⚠️ **A prompt must never be written into the pane as ONE burst**: Claude Code 2.1.283 takes a `<text>\r` burst of ~100+ chars as a paste, its `\r` lands as a NEWLINE and the prompt strands (a later raw `\r` does not recover it, a tmux `send-keys Enter` does). So `POST .../input` routes a plain prompt (`isPlainPromptInput()`, route-helpers.ts: printable text + exactly one trailing `\r`) through `writeViaMux` even without `useMux`, AWAITED so the browser's serialized POST fallback keeps frame order; raw frames and an explicit `useMux:false` keep the direct write
+- **A prompt is one paste plus Enter** — `writeViaMux()` sends the text as one bracketed paste and Enter separately. ⚠️ **Input must END with `\r` or Enter is never sent**: `sendInput()` only issues `send-keys Enter` when the payload contains a carriage return, a `\r`-less `POST /api/sessions/:id/input` still succeeds (send-and-wait even reports `delivered:true`) while the text sits unsubmitted on the composer, and any `wait` burns its whole timeout on a turn that never started. Embedded newlines are kept (`\r\n` becomes `\n`): all lines go in as that ONE paste and the Enter after it submits them together, so `"echo A\necho B\r"` runs both commands in a shell (bash holds the pasted lines until the Enter; a shell without bracketed paste runs each line as it arrives). Multi-line text WITHOUT `\r` is pasted the same way; on a pane that has not enabled bracketed paste (POSIX sh, macOS `/bin/bash` 3.2) tmux delivers every line break as a CR, so every line but the last runs, where the old line-stripping typed the joined text and ran nothing. Leading and trailing line breaks are dropped. ⚠️ `SubmitVerifier` cannot reliably recognise a multi-line paste in the composer: it matches one Claude shows inline whose first line has 24+ non-space characters, but misses a short first line and the `[Pasted text #N +k lines]` placeholder, so it may not re-press a stranded Enter for one. ⚠️ **Claude Code 2.1.277+ ignores Enter for the first 30-50 s after the composer paints** while still taking the typed text (measured 2026-09-19: an Enter at 28 s stranded the prompt, one at 51 s submitted it), so text+`\r` sent at readiness sits unsent with `0 tokens` and a `wait` burns its timeout.

 - **ESM only** — Never `require()`, use `await import()`. `tsx` masks CJS/ESM issues in dev but production breaks

 - **Effort is NOT an env var** — never carry effort as `CLAUDE_CODE_EFFORT_LEVEL`: the env var hard-locks effort and blocks in-session `/effort` switching (incl. ultracode). It flows as the dedicated `effort` payload field → `Session._effort` → `claude --effort <level>` for regular levels incl. `max` (the settings `effortLevel` key is `enum(["low","medium","high","xhigh"]).catch(undefined)` — `max` gets SILENTLY dropped there), or `claude --settings '{"ultracode":true}'` for ultracode (rejected by `--effort`). Both are soft defaults the user can override anytime. Legacy env-var entries are auto-migrated by the Session constructor and unset from tmux sessions in `applyEnvOverrides()`. See `buildEffortCliArgs()` in `session-cli-builder.ts`, tests in `test/effort-injection.test.ts`
 - **The advisor rides `--settings`, NEVER the `--advisor` flag**: Claude Code's advisor tool (a stronger model consulted at decision points, code.claude.com/docs/en/advisor) flows as the `advisorModel` payload field → `Session._advisorModel` (persisted, so respawn and reboot restore keep it) → the `advisorModel` key in the launch's ONE `--settings` JSON, merged with ultracode and the statusLine exporter by `buildAdvisorSettings()` (`session-cli-builder.ts`). ⚠️ The flag EXITS at launch on any pairing the CLI refuses (`claude --advisor haiku` exits 1, so does Fable before its usage-credit consent), which would leave a dead pane on every respawn; the settings key degrades to "no advisor" instead. ⚠️ `isAdvisorModel()` (fable/opus/sonnet aliases or full ids, no haiku) is also the injection guard for the single-quoted argument. Soft default: `/advisor` still switches it in-session. App Settings key `claudeAdvisorModel` (SYNCED, `''` = leave it to the CLI). Remote/docker quick-start refuses it, like `effort`, and so does a remote attach on `POST /api/sessions`. Tests: `test/advisor-model.test.ts`
 - **Model choice: a persistent default in `settings.local.json`, a per-session `--model`, never env** — the App Settings **Claude Model** picker (`claudeModel` in `settings.json`) is read by `session-ui.js` at session create (wins over the legacy 1M-Opus toggles `opusContext1m`/`opusContext1mEnabled`), sent as the `modelOverride` payload field, and `updateCaseModel()` (`hooks-config.ts`) writes/deletes the `model` key in `<case>/.claude/settings.local.json`. This is the intended exception to the envOverrides rule above: model legitimately lives in `settings.local.json` (a soft default — in-session `/model` still works); env vars do not. A caller that wants one session on a model without touching the case sends `model` on `POST /api/sessions` instead: it goes out as `claude --model <id>`, writes nothing, wins over the app-wide default, and is persisted as `SessionState.model` so both recovery paths relaunch on it (`test/routes/session-routes-claude-model.test.ts`, `test/session-model-recovery.test.ts`). ⚠️ Claude only, via the `model.source` capability (`cliTakesSessionModel()`), never a mode check: refused for other CLIs and on a remote attach, and published by `toState()` for claude alone (cron hands its Claude default to every CLI with a model).
-- **Multi-CLI prefix discipline** — env-var prefix is CLI-specific (`CLAUDE_CODE_*` vs `OPENCODE_*` vs `CODEX_*` vs `GEMINI_*` vs `ANTIGRAVITY_*` vs `PI_*` vs `GROK_*` vs `DSH_*`) and the `ALLOWED_ENV_PREFIXES` allowlist in `schemas.ts` enforces this; non-prefix exceptions are exact keys in `ALLOWED_ENV_KEYS` (currently only `CLAUDE_CONFIG_DIR`), never a widened prefix. Gemini additionally allowlists the **broad `GOOGLE_*`** namespace (intentional: Vertex AI auth needs `GOOGLE_CLOUD_PROJECT`/`GOOGLE_APPLICATION_CREDENTIALS`/`GOOGLE_GENAI_USE_VERTEXAI`; it is the loosest allowlist entry, affecting only the user's own spawned CLI), and Grok allowlists **`XAI_*`** for the same vendor-namespace reason (`XAI_API_KEY` is grok's documented auth var). When adding a setting, decide which CLI(s) it applies to and gate the env export accordingly. Never blanket-forward all prefixes. ⚠️ Pi is the case that proves the rule: its ~34 provider keys (`ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, `HF_TOKEN`, …) share NO prefix, and the allowlist is one GLOBAL list applied by a refine with no mode context, so admitting them for pi would widen it for every mode at once — they stay out, and pi users authenticate via `/login` or the server process's own env. ⚠️ DeepSeek repeats pi's lesson exactly: a dsh `settings.yaml` can nominate ANY env var as a provider credential (`apiKeyEnv`), so only the vendor namespaces `DSH_*` (launcher inputs incl. `DSH_PERMISSION_MODE`) and `DEEPSEEK_*` (`DEEPSEEK_API_KEY`/`DEEPSEEK_BASE_URL`) are admitted; foreign provider keys authenticate from dsh's own files or the server env.

 - **Zod `.optional()` rejects `null`** — accepts `undefined` only. When the frontend builds a request body with `JSON.stringify`, an explicit `null` field is preserved on the wire and fails validation with `INVALID_INPUT`. Convert `null` → `undefined` before stringifying (e.g. `field: value ?? undefined`), or declare the schema `.nullish()`. This has caused real shipped bugs twice
 - **Local-echo overlay stays on screen**: the overlay lays its wrapped lines out DOWNWARD from the prompt row, and the text has not reached the PTY yet, so the CLI never learns the prompt is long and nothing scrolls to make room. With the keyboard up only a handful of rows are visible, so a long prompt used to run off the bottom and the user typed blind. The block now grows UPWARD once it would pass the last visible row (optional `totalRows` in `RenderParams`; the line divs are opaque, so they cover transcript above), and a prompt taller than the viewport keeps its TAIL. ⚠️ Separately, `_shrinkPaddingToFit()` (mobile-handlers.js) must never shrink `main`'s padding-bottom below the MEASURED height of the fixed bars: on phones the toolbar and accessory bar are `position: fixed`, so that padding is the only thing reserving room for them, and taking it pulled the terminal's bottom row behind them. Tests: `packages/xterm-zerolag-input/test/overlay-renderer.test.ts`, `test/mobile-keyboard-bottom-padding.test.ts`.
 - **`xterm-zerolag-input` is single-source** — BOTH echo addons live ONLY in `packages/xterm-zerolag-input/src/`, bundled into TWO **gitignored** vendor files: `vendor/xterm-zerolag-input.js` (buffer overlay, entry `zerolag-input-addon.ts`) and `vendor/xterm-predictive-echo.js` (codex write-through, entry `predictive-echo-addon.ts`) — dev by `scripts/postinstall.js`, prod by `scripts/build.mjs`. `app.js`/terminal-ui.js only **consume** them via `new LocalEchoOverlay(terminal)` / `new PredictiveEchoOverlay(terminal)`; there is no inline copy. So: change the package source, then rerun the bundle step (`npm install` for dev, `npm run build` for prod). **Never hand-edit `app.js` for overlay behavior, and never commit the gitignored vendor bundles.** Always test on mobile after touching it. → [architecture-invariants#xterm-zerolag-input-is-single-source](docs/architecture-invariants.md#xterm-zerolag-input-is-single-source), `docs/local-echo-overlay-plan.md`
 - **Default bind is loopback-only; non-loopback without a password starts but warns** — the server defaults to `--host 127.0.0.1`. Binding non-loopback (`--host`/`-H`/`CODEMAN_HOST`) without `CODEMAN_PASSWORD` starts anyway but prints a loud warning; `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` acknowledges it. ⚠️ The production systemd unit passes no `--host`, so prod binds **localhost only**: reach it via `tailscale serve`/tunnel to `127.0.0.1`. A loopback bind is reachable through a same-host tunnel but NOT by a browser hitting the box's LAN IP. `install.sh` is separate and prompts for the binding (defaulting to LAN + a password), and preserves the existing binding on re-runs. → [architecture-invariants#default-bind-and-the-non-loopback-warning-path](docs/architecture-invariants.md#default-bind-and-the-non-loopback-warning-path), `docs/security-architecture.md`
 - **Instance isolation / multi-instance attach danger** — the data dir (`~/.codeman`) and tmux socket (`tmux -L codeman`) are PROCESS-WIDE and shared by every Codeman on the machine, derived from `CODEMAN_INSTANCE` via `src/config/instance.ts`. ⚠️ A 2nd instance on the SAME socket **discovers and attaches PTYs to the first instance's live sessions**, resizing and mutating them. `$HOME` isolation is NOT enough because tmux is system-global. To run two instances, give each a distinct `CODEMAN_INSTANCE` (scopes dir + socket together), or set `CODEMAN_TMUX_SOCKET` + `CODEMAN_DATA_DIR` individually; `scripts/run-beta.sh` does this for a beta alongside prod. **Any new `~/.codeman/...` path MUST go through `dataPath()`**, never `join(homedir(), '.codeman', …)`, and **any new `tmux -L` caller through `resolveTmuxSocketName()`** (both in `config/instance.ts`): the TUI shells out to tmux from a second process, and a hardcoded `codeman` there would point a beta instance at prod's panes. → [architecture-invariants#instance-isolation-and-the-multi-instance-attach-danger](docs/architecture-invariants.md#instance-isolation-and-the-multi-instance-attach-danger)
+- **The prefix table on Codeman's socket holds only `<prefix> send-prefix`** — browser tabs are tmux attach clients, and tmux's stock bindings let Ctrl+B `)`/`s` move a tab onto another session. `createSession` resets the table, and `reconcileSessions()` at boot for sessions that survived an upgrade (`src/tmux-prefix-table.ts`); `root` and `C-<letter> detach-client` (the TUI attach's way out) are left alone, so while a `codeman tui` attach is open its `root` keys reach browser tabs too, Alt+1..9 `switch-client` included (open follow-up). ⚠️ So `Ctrl+B d` does not exist there: anything attaching a user's terminal claims its own detach key (F1 in `root`, as `codeman tui` and `scripts/tmux-manager.sh` do). → [architecture-invariants#the-prefix-table-on-codemans-socket-holds-only-send-prefix](docs/architecture-invariants.md#the-prefix-table-on-codemans-socket-holds-only-send-prefix)
 - **node-pty's macOS `spawn-helper` ships without `+x`** (issues #6, #204): `node-pty@1.1.0` publishes `prebuilds/darwin-<arch>/spawn-helper` as mode 0644, and macOS launches every PTY through it, so a stock macOS install fails every session start with `Error: posix_spawnp failed.` **Linux can never reproduce it**: `spawn-helper` is an `OS=="mac"` gyp target and node-pty ships no Linux prebuild, so node-gyp always emits an executable helper there. ⚠️ The flip side of that: since Linux has no prebuild, `npm install` **needs a C/C++ toolchain there** (`make`, `g++`, `python3`), so `install.sh` checks for and installs one alongside Node/tmux/git — a stock Ubuntu 24 server has none and died inside node-gyp with `not found: make`. Do not drop that step. ⚠️ Look in **`prebuilds/<platform>-<arch>/`**, not just `build/Release/`, which does not exist on macOS. Repair is a chmod, never a mandatory rebuild (that would require Xcode CLI tools and deletes `prebuilds/` before compiling): `npm run fix:node-pty` chmods every helper then proves it by really opening a PTY. `spawnPtyWithHelperRepair()` (`utils/node-pty-repair.ts`) wraps every `pty.spawn()` in `session.ts` and self-heals a broken install on the first failure. → [architecture-invariants#node-ptys-macos-spawn-helper-must-be-executable](docs/architecture-invariants.md#node-ptys-macos-spawn-helper-must-be-executable)
 - **User-chosen paths are probed BOUNDED, never with `existsSync`/`statSync`** (#516): a linked case or a `workingDir` can sit on a network mount that stopped answering. A synchronous check there freezes the whole server, and an unbounded async `stat`/`lstat`/`readFile` holds one of libuv's threadpool workers (4 by default, shared with every `fs`, `dns.lookup` and `crypto` call) until the mount returns. On a request or spawn path use `probePath()`/`probePathKind()` (`utils/bounded-path-probe.ts`, read its `@fileoverview`). ⚠️ `unknown` is NEVER `absent`: nothing is created, scaffolded or 404'd on it. Bulk scans keep the stall cap; a request for ONE path the user named may pass `{ pastCap: true }`, which still stops at the ceiling that keeps one worker free; and a helper that would otherwise touch the path skips whatever is still `unknown`. User-facing errors for it go through `describeUnknownPath()`, so a refused probe is not reported as a broken folder.
 - **Headless screenshots: `deviceScaleFactor` MUST be 1, and write unique filenames** — under DSF=2 xterm's WebGL renderer draws glyphs at ~2× nominal size while still *reporting* nominal cell dims, so only the pixels reveal it and only the terminal font looks wrong. And overwriting a fixed output path leaves OS image viewers showing the old render, which reads as "the fix didn't work"; `scripts/capture-real-overview.mjs` mints a timestamped filename per run. Seed the per-device `localStorage` keys (`codeman:skin`, `codeman-font-size`, `codeman-app-settings`) so the capture matches a real device. → [architecture-invariants#headless-screenshot-capture](docs/architecture-invariants.md#headless-screenshot-capture)

 ### Key Patterns
 
-**Input**: `session.writeViaMux()` for programmatic/curl input via tmux `send-keys -l` + `send-keys Enter`, single-line only. Interactive **browser** input goes through a durable **exactly-once** layer: a stable `clientId` + monotonic per-session `seq` persisted to localStorage until the server ACKs, so a dropped link cannot lose or double-deliver a prompt. `ws-connection-registry.ts` supersedes only same-TAB reconnects, so two tabs on one session coexist. → [architecture-invariants#input-delivery-and-ws-resilience](docs/architecture-invariants.md#input-delivery-and-ws-resilience)
+**Input**: `session.writeViaMux()` for programmatic/curl input via one tmux bracketed paste (`paste-buffer -p`) + `send-keys Enter`; a multi-line prompt keeps its line breaks inside that paste. A single character is typed with `send-keys -l` instead, because selection dialogs ignore a pasted digit. Interactive **browser** input goes through a durable **exactly-once** layer: a stable `clientId` + monotonic per-session `seq` persisted to localStorage until the server ACKs, so a dropped link cannot lose or double-deliver a prompt. `ws-connection-registry.ts` supersedes only same-TAB reconnects, so two tabs on one session coexist. → [architecture-invariants#input-delivery-and-ws-resilience](docs/architecture-invariants.md#input-delivery-and-ws-resilience)
 
-**Agent wait primitives**: bounded long-polls: `GET /api/sessions/:id/wait`, `GET .../wait-output` (literal substring, **never** regex) and `wait`/`waitTimeout` on `POST .../input`. Registry `session-wait-registry.ts` (pure), bounds `config/agent-wait.ts`. ⚠️ A timeout is a 200 (`wait.timedOut`). ⚠️ `stop`/`blocked` exist for `claude` and `deepseek` ONLY (rule lives in `hooksAvailableForMode()`): explicit request elsewhere is a 400. ⚠️ Send-and-wait registers the waiter BEFORE the write; teardown must `notifySignal('exit')` BEFORE `cancelAll()`; hangup abort listens on `reply.raw` (guarded by `writableFinished`), never `req.raw`; liveness comes from `isPaneDead`, never `session.pid`. ⚠️ Signals are edge-triggered with no history: gather fan-outs via send-and-wait or `wait-output` markers. Packaged as the `skills/codeman` skill (`codeman skill install`, plugin marketplace, or injection behind `agentSkillEnabled`, SYNCED, default OFF, into the directory each CLI scans: `capabilities.agentSkillDir`, `.claude/skills` for claude, `.agents/skills` for the others, none for pi): injection is add-only, marker-owned (`applyAgentSkill`), refuses symlinks, and refreshes a marker-owned user-level copy (`refreshUserAgentSkill`). → [architecture-invariants#agent-wait-primitives](docs/architecture-invariants.md#agent-wait-primitives), `docs/api-reference.md`

 **Agent CLI (`codeman agent …`, `src/cli-agent.ts`)**: the command-line client for the wait primitives and the session verbs, for agents the skill does not reach (pi, shell, no `jq`; `seedAgentSessionPreamble` covers every local session whose CLI takes the skill, `capabilities.agentSkillDir`; every pane still exports `CODEMAN_MUX`/`CODEMAN_SESSION_ID`/`CODEMAN_API_URL`). It is a CLIENT: no new route, no second transport (the plan's "Socket API" non-goal stands), every call carries `X-Codeman-Parent-Session`, only `spawn`'s quick-start carries `X-Codeman-Agent-Origin` (pinned in test/cli-agent.test.ts), auth (`src/codeman-credentials.ts`, shared with `codeman attach` and the TUI) from `CODEMAN_PASSWORD` or the data dir's `.env` (the same reader `codeman attach` uses — `readCodemanEnvFile`). Verbs return exit codes (`0` ok / `1` error / `2` timeout / `3` exited / `4` refused) instead of calling `process.exit`, so `test/cli-agent.test.ts` drives every verb against a recording fake transport plus the real `httpRequest` against a local server. ⚠️ Three guards live in code, not prose, and the tests pin them: refuse without `CODEMAN_MUX=1`+`CODEMAN_API_URL` (never guess a URL); `send` transmits printable text + `\r` only (`inputRefusal`: any byte < 0x20 or DEL refuses BEFORE the transport — opencode's `Ctrl+C` is `app_exit`), ESC exists solely as `interrupt` with no `\r`; `rm` fails closed (`deleteRefusal`: empty id, self shorter than 8, prefix match in EITHER direction, re-checked on the resolved id). ⚠️ The routes accept FULL ids only — an 8-char prefix is a 404 (measured live) — while `ls` prints prefixes, so `resolveSessionId` maps a short id through `GET /api/v1/sessions` and refuses an ambiguous one. It also refuses any id under 8 characters (exit 4, on every verb, before any request), the same floor as the server's `PARENT_SESSION_ID_MIN_PREFIX`, so `rm 9` can never pick an arbitrary session. ⚠️ A 400 for `--until stop` on a hook-less mode is passed through verbatim, never papered over: the marker path is the answer there. `spawn` on a readiness timeout exits 2 and LEAVES the session for inspection (the skill's `spawn_worker` deletes it; the CLI's caller is often a human); its stdout is the id ALONE (prose on stderr) so `SID=$(…)` works. ⚠️ Two server answers that look like success and are not: `delivered:false` without `duplicate` (the bytes went into a dead pane — the field exists so a client says "restart" instead of "wait longer") and `wait.ended:true, signal:null` (the worker died during a `stop`/`idle` wait: the registry satisfies only waiters that listed `exit`, then cancels the rest) — both exit 3, checked BEFORE the happy paths in `waitExitCode`. → README "`codeman agent`", `docs/api-reference.md`

+⚠️ **A codex dialog is BLOCKED, read off the screen, and only ever an ALERT.** Codex has no hook for its approval, question and trust dialogs, so `capabilities.workDetect.blockedLine` names their chrome and `web/screen-blocked.ts` raises what a `permission_prompt` hook raises, as an `answerInTerminal` item. ⚠️ Never key a keystroke off that match (the agent writes most of the pane), and never hand its item a `capture` (the inbox's sweep is Claude-shaped; the session's 2 s re-read owns the clear). A blocked screen beats the working line. → [architecture-invariants#screen-read-blocked-dialogs-codex](docs/architecture-invariants.md#screen-read-blocked-dialogs-codex)
+
 ⚠️ **A quiet pane is not always a pane that wants you.** A CLI can declare an optional `capabilities.workDetect.watchingLine` (a monitor, background shell or cloud hand-off it is still running); the idle probe reads it into `Session.watching` and `notePrompt()` opens that idle item ALREADY acknowledged, so no surface alerts. Only `idle` is eligible, and the label is pane-derived and prompt-injectable, so a pattern must anchor on chrome only that CLI draws. → [architecture-invariants#the-watching-signal-a-quiet-pane-that-is-not-waiting-for-you](docs/architecture-invariants.md#the-watching-signal-a-quiet-pane-that-is-not-waiting-for-you).

 **An exited agent in a live pane** (`paneExit`, #446): panes use `remain-on-exit on`, so `/exit` leaves a pane, session and pid that look alive; `TmuxManager.startPaneExitWatcher()` publishes `SessionState.paneExit` via `session:updated`. ⚠️ Never set `status: 'error'` or null the `pid` for it; the field is TRI-STATE (absent = UNKNOWN, never alive, scoped by `Session.paneExitApplies`); an absent `#{pane_dead_status}` is not 0; a path that starts a command in a pane must clear the record AND persist. A clean exit is CLOSED via `cleanupSession()` (`pane-exit-sweep.ts`): only an explicit numeric status 0 with no signal, confirmed by 2 reads, with no start/attach in flight (`paneLifecycleInFlight`) and not within 10 s of one (a startup error keeps its row); a crashed agent keeps its row. → [architecture-invariants#an-exited-agent-in-a-live-pane-paneexit](docs/architecture-invariants.md#an-exited-agent-in-a-live-pane-paneexit)
 
 **Dead-pane respawn resume pin** (`_buildRespawnPaneOptionsWithResumePin()`, session.ts): recovering a dead pane, like a custom-model `restartCli()`, must pin the conversation or claude refuses the reused `--session-id`.

Codeman owns the idle policy for these sessions: a launch with keep-warm on also carries `"idleCompaction": false`, folded LAST into the ONE `--settings` JSON (`session-cli-registry-bridge.ts`), decided once per create/respawn by `decideIdleCompactionOptOut()` (tmux-manager.ts: keep-warm on via `keepWarmOn()`, exporter `injected`, claude's `idleCompactionSetting` gate at 2.1.290, fail-closed like `--name`) and recorded as `MuxSession.idleCompactionOff`; a keep-warm-off launch stays byte-identical (`test/cli-registry-spawn-golden.test.ts`). Switched on after launch it is best-effort and the readout says idle compaction may still run until the next launch. ⚠️ The deadline is `Session.promptCache.expiresAt` from the statusline, never idle detection or the plan tier; a `5m` TTL is a hard stop, and so is a launch whose `statusLineExporter` is not `injected`. ⚠️ Every guard lives in the pure `decideKeepWarm()` (effective opt-in, where an agent-spawned session (`parentSessionId`) does not inherit the app default; exporter injected; warm; no `compactedAt` this gap; tokens at stake; live pane (pid AND no `paneExit`); no limit pause (auto-resume's, or a limit message on screen); no respawn/Ralph/task/waiter; inside the cap since `lastRealPromptAt`; idle; no dialog; EMPTY composer via `composerIsEmpty()`, continuation lines included, read from a STYLED capture so Claude Code's faint prompt suggestion is not taken for a draft; no recent keystroke); add a guard there, never in the service. ⚠️ The nudge IS a submit and moves `lastSubmitAt` (the response viewer's conversation correlation needs it); the window `beginKeepAliveTurn()` opens keeps it off `lastRealPromptAt` (the cap's own persisted clock) and opens its `stop`/`idle_prompt` hooks pre-acknowledged (`preAcknowledged` on `notePrompt`), so nothing alerts, and leaves an idle item already pending exactly as found (only a human spends an idle alert; `session:working`/`session:idle` carry `keepAlive: true` so the page's stuck timer ignores the turn); the keep-alive's own `idle_prompt` ends that window (`endKeepAliveTurn()`; `KEEP_WARM_TURN_WINDOW_MS` is only a ceiling, since a slow turn's idle prompt lands a minute after it ends), so does a nudge whose write failed (retried a minute later, never past the last-chance line), and so does any other submit: a `fromUser` write, a programmatic write of anything but the nudge, or a `prompt_submitted` hook whose prompt is not the nudge.

 **Orchestrator**: State machine that turns a user goal into a phased plan and drives it to completion: `idle → planning → approval → executing → verifying → (replanning) → completed/failed`. `OrchestratorLoop` (engine) delegates plan generation to `orchestrator-planner` and per-phase verification gates to `orchestrator-verifier`, executing phases via team agents/`task-queue`. State persists under the `orchestrator` key in `state.json`. Distinct from Ralph (single-session autonomous loop) — orchestrator coordinates multi-phase, multi-agent execution.

Where each CLI keeps the file is registry data, `capabilities.mcpConfig` (`{ path, format, relocation? }`), never a branch on the id. ⚠️ Tools that sync but are not run modes (GitHub Copilot CLI, the first) are plain data in `MCP_SYNC_ONLY_TOOLS` (`src/mcp-sync-targets.ts`), take part only when installed or already configured, and their companion `settings.json` (`disabledMcpServers`) is read, never written; a test must clear their relocation vars too. ⚠️ ADDITIVE only: a name already defined, in any shape, is never edited or removed (a different same-name definition is a reported conflict), and a server switched off in its own CLI is never copied. ⚠️ Never write a file that did not parse; re-parse the NEW text and require every added server to read back before the tmp+rename (written through a symlink, previous file kept as `<file>.codeman-bak`, one apply at a time, else 409). ⚠️ A file that receives copied `env`/`headers` (secrets) is left `0600`, and so is the backup. ⚠️ Responses carry server NAMES only, never env values, headers or file text: a parse failure is reported by line and column (`describeMcpSyncError`), never the parser's own message (smol-toml and V8 both quote source). ⚠️ `mcpConfig.relocation` names the env var the CLI reads to move its file (`CLAUDE_CONFIG_DIR`, `CODEX_HOME`, `XDG_CONFIG_HOME`, `GEMINI_CLI_HOME`, and `COPILOT_HOME` for Copilot), resolved from the SERVER env at call time; a relative value reports the target `skipped`, never a guessed write, and a per-session `envOverrides` relocation is not followed. Tests must pass `home` (which drops the `process.env` default) or clear those vars first. → `docs/cli-registry.md` (MCP server sync), `docs/api-reference.md`, `docs/wiki/Settings-Reference.md`
 
-**Run launch synchronization**: the Run entrypoint holds an in-flight lock and disables `#runBtn` for the whole launch (≥500ms) so a double click cannot create duplicate `w<n>-<case>` sessions; `_ensureCreatedSessionVisible()` runs before `selectSession()` and `_onSessionCreated()` stays an idempotent upsert, so POST-first and SSE-first both render exactly one tab. ⚠️ **Closing has the mirror-image race**: `closeSession()` must read `wasActive` BEFORE its `await` and announce the delete via `_closingSessions`, and `_onSessionDeleted` skips the active-session handoff for ids in that set; never read `activeSessionId` after the fact. The fallback picks the first `sessionOrder` entry still in `sessions`. ⚠️ The close is OPTIMISTIC: the tab goes and the next one is selected BEFORE the DELETE is sent (upserts skip ids in `_closingSessions`), and only a delete the server refused (checked with a GET) puts the row back; never await the server before hiding the tab. Tests: `test/session-close-fallback.test.ts`. → [architecture-invariants#run-launch-synchronization](docs/architecture-invariants.md#run-launch-synchronization)
-
-**Session lineage lines** (tab → tab it spawned, `sessionLineageLines`, per-device, desktop default ON): a create request may name its spawner via a `parentSessionId` body field or the `X-Codeman-Parent-Session` header; `resolveParentSessionId()` (route-helpers.ts) resolves it (exact id or unique ≥8-char prefix, live, visible, same owner) and ⚠️ anything unresolvable is DROPPED, never a 400. Rides `toState()`, no new SSE event. ⚠️ Rendering is a LAYER on the existing SVG pass (`_appendLineageConnectionLines` at the tail of `_updateConnectionLinesImmediate()`) and draws EVERY family, emphasizing the selected tab's (what it spawned, and the family it was spawned into: `lineage-family--focus`, thicker, opaque, drawn last; lanes stay in strip order), so a selection change must redraw (`_updateActiveTabImmediate`, gated on `_lineageTotalEdges`), and again on the strip's size `transitionend` (the active tab widens for ~150ms after the redraw). Geometry is pure in `computeLineageTree()`: one rounded orthogonal tree per spawning tab, every route starting at the PARENT (siblings share the trunk exactly), routed ONLY through the gaps between tab rows plus a spine left of every row, so it never crosses a tab or the terminal. ⚠️ That room is reserved in CSS by `.session-tabs.lineage-tree` (`_syncLineageGutter()`, called before the wrap is measured), keyed on whether ANY family exists, never on the selection, or every tab switch would resize the header and the PTY. Colors are keyed on the SPAWNING tab, claimed in strip order for every family, and memoized (never by draw index or selection order). ⚠️ Desktop only (z-index vs the fixed mobile header). ⚠️ Paths must keep `data-agent-id="lineage:<childId>"` (the entrance animation queries it); skip endpoints scrolled out of the strip. → [architecture-invariants#session-lineage-lines-tab--tab-it-spawned](docs/architecture-invariants.md#session-lineage-lines-tab--tab-it-spawned)

-**Auto-named sessions** (`autoNameSessions`, SYNCED, default OFF): a placeholder tab (`w3-myapp`) takes its first real prompt as a title in the `<prefix>: <title>` form, so the case identity and `w<n>` counter survive. Ownership is `SessionState.nameSource` (`placeholder` | `auto` | `manual`; the `name` setter / `PUT /api/sessions/:id/name` makes it `manual`, never touched again). ⚠️ `applyAutoName()` flips to `auto` even if the string is unchanged, so only the FIRST titled prompt names the tab. ⚠️ Only user input counts: `SessionWriteOptions.fromUser` is set by the browser WS path and `POST /api/sessions/:id/input` ONLY; any new user-input path must set it (and the send-key Shift+Enter path must call `trackUserInput()`). ⚠️ The pure tracker (`session-auto-name.ts`) sits on the raw keystroke stream with an explicit rule per key; add a rule for any new key class. ⚠️ `nameSource` also decides `--name`: only a `manual` name is pinned on the claude CLI (`Session.cliPinnedName`), since `--name` is also the `/resume` title; a rename appends a `custom-title` row to a LOCAL, non-docker transcript, and a same-name PUT is a no-op (never flips to `manual`).

 **Maintainer bot (external)**: the Telegram bot that reviews open PRs and triages discussion threads in Codeman sessions used to live at `scripts/pr-bot/`. It moved OUT of this repository on 2026-09-14, to `~/codeman-cases/prbot/` (its own private git repo, systemd unit `codeman-pr-bot`, guide + agent rules in its own `README.md` and `CLAUDE.md`). It is a CLIENT of Codeman's HTTP API like any other, so nothing here depends on it and it is not part of the server, the CLI or the npm package. ⚠️ It spawns real sessions named `prbot-<n>` / `dscbot-<n>` on the local Codeman and holds clones under `~/.codeman/pr-bot/`, so those session names and that data dir are taken; it also fetches PR heads into `refs/pr-bot/*` of this checkout and must never check out, reset or clean it. The CHANGELOG entries for 1.25.0 and earlier still describe it, which is history rather than drift.
 
 **Unified session list**: `GET /api/sessions/unified` merges live sessions, persisted state, lifecycle-log history and transcript files into one deduped list (pure core `src/services/unified-session-service.ts`), backing the Cmd+K Session Manager, pinning and cross-device tab order (`PUT /api/session-order`, `src/session-order.ts`). ⚠️ Transcript history is THREE stores (`~/.claude/projects`, `~/.omp/agent/sessions`, `~/.codex/sessions`), folded via the `claudeSessionId → Codeman id` alias map (not Claude-only despite the name). ⚠️ `resumeId` is set by a SCANNER row only, never a live session; every surface that re-projects these rows (phone overview included) must carry it through, or a tap silently starts a second conversation. → [architecture-invariants#unified-session-list-and-session-manager](docs/architecture-invariants.md#unified-session-list-and-session-manager)
 
-**Owner tab layouts** (`tab-layout*.ts` + `GET`/`PUT /api/tab-layout`): named tab GROUPS over the flat strip, scoped per owner (`@single` when multi-user is off), persisted as `tabLayouts` in state.json. The frontend reads AND edits it (`tab-layout-browser.js` + the grouped-rail block in app.js): the vertical rail draws the owner's groups as collapsible sections (collapse is per-device localStorage), and with no groups or a failed read the rail is the flat list. Groups are created, renamed, reordered and deleted, and rows moved between them, from the row/group menus (Shift+F10 on a header too) and by pointer drag in the grouped rail. A ref may carry `focus: true` ("Add to Focus" in the row/web-tab menu, the named `setFocus` operation): the rail then draws a SHORTCUT to it in a pinned, collapsible Focus section (`_renderTabFocus()`), its own element in `#tabRail` ABOVE `#sessionTabs`, so it shows on the flat rail too and is never a row, tree item, Alt+N slot, lineage anchor or drag target. ⚠️ Every copy of a ref (`copyRef` in tab-layout-browser.js, `parseRef`/`mapRef` in tab-layout.ts) must carry `focus` like `placement`: the browser PUTs whole layouts, so a dropped field is erased on the next save by whoever saves. ⚠️ Grouping is a render layer only: `sessionOrder`, Alt+N and every other order consumer still read the server-projected session order, and a grouped row's markup is the flat row's markup. ⚠️ Only the GROUPED rail is an ARIA tree (`role=tree`, headers owning `role=group`s, one roving `tabindex=0`); the strip, sidebar and flat rail stay `tablist`/`tab`. ⚠️ Every browser write is a named operation through ONE serialized `PUT /api/tab-layout` at a time (`createEditCoordinator`): a 409 replays the operations onto the server's layout and retries (bounded), and an SSE reload is deferred while a write is in flight.

A spawned child lands after its parent; whether it keeps FOLLOWING it until moved by hand is the synced `spawnedTabsFollowParent` setting (default OFF: pinned `manual` in the creating write), read fresh in `sessionCreated()`. ⚠️ A legacy order PUT marks a child `manual` ONLY when the requested order splits it from its parent's block (`applyLegacySessionRank`), and the browser never echoes create/delete through `PUT /api/session-order`: the server already re-projected and broadcast it. Web-tab OPENNESS stays per device. ⚠️ `TabLayoutService` is the single mutation boundary (one completed server action = at most one versioned write); never write layout state from a route or manager directly. ⚠️ The layout PROJECTS onto `PUT /api/session-order` via `tab-layout-legacy-order.ts`; change both sides together. ⚠️ Reconciliation is gated on a SUCCESSFUL restore (`markRestorationComplete`/`assertDeletionReady()`): a failed restore must leave the layout untouched or live tabs get pruned. → [architecture-invariants#owner-tab-layouts](docs/architecture-invariants.md#owner-tab-layouts)

Pane B reconnects after a drop, sends input through the exactly-once queue over its own socket (`_registerInputSocket`), has clickable paths and image paste, and owns its geometry (no 40x10 floor, `zc` columns adopted, font changes call `tile.fit()`). ⚠️ Only typed input enters that persisted queue: xterm's query replies are dropped and focus/mouse reports go out ephemeral. ⚠️ App-level terminal actions find their pane through `_focusedPane()` (the terminal focused last), never `this.terminal`.

While the grid is open the main terminal is PARKED: `activeSessionId` is the focused tile's session, and every main-terminal path that would write, fetch, resize or reconnect stands aside through `_tilesOwnTerminal()` (the WebGL long-task observer included). ⚠️ Every capture a tile fetches (initial, reconnect refresh, `{t:'r'}`, history pull) goes through ONE `TileLoadQueue` (concurrency 1, a deadline covering the body), because each is a synchronous tmux call on the server. ⚠️ Only a USER-initiated pick of a non-tiled session (or `leaveTiles`, a followed link) leaves the grid; an `auto` selection never collapses it, and every app-driven fallback (close, delete, restore) picks a tile. A caller of `closeTileGrid({ reselect: false })` must null `activeSessionId` before any `_cleanupPreviousSession`, or the parked terminal's stale content is saved as a snapshot. ⚠️ The grid and the split are never open together. ⚠️ Tile chords go through `tileShortcutFor` and are swallowed in every xterm key handler BEFORE the Shift+Enter gate; the toggle follows `showTileGridButton` (owner decision: OFF makes the chord inert, it passes through like any unbound key). ⚠️ The Tiles button's click and Ctrl+Shift+G are ONE function, `toggleTileGrid` (owner decision): they open the grid AT ONCE on `tileGridOpenSet` (constants.js): the stored grid EXACTLY as the user left it (owner decision 11: `restoreTileGridCells`, never filled to the count nor trimmed to the window; a cell whose session is gone since is filled from the ranking, a hole the user made stays), else an open split's two, else the open sessions as `rankTileSessions` orders them (working first, keyed off `lastSubmitAt` ONLY, then needing input, then most recent; `_mobileOverviewState`'s states), the active one focused, filled to the remembered count (`codeman:tile-count`, default 6, at most `_tileGridLimit()`) by `tileGridSetForCount`, never a menu. ⚠️ `removeTile(..., { gone: true })` (a session deleted, popped out or refused) keeps the stored `count` so the next open refills that cell; a removal by hand lowers it. Right-click is the 2 / 4 / 6 count menu (`openTileCountMenu`, owner decision 10), which owns its Escape. The button has no native title: its hover card (`_installTileGridHint`, `#tileGridHint`) says it, is its `aria-describedby` (always present, hidden, kept current) and hides in the capture phase on any press, click or right-click, so the menu never opens beside it. ⚠️ The open, the count menu and the toggle's close animate opacity and transform only (the close leaves an inert cloned still copy until the single view's selection settles, at most 700 ms); nothing moves under `prefers-reduced-motion`. ⚠️ Opening builds one tile terminal per frame (`_connectTilesPaced`), so `openTileGrid` returns before the terminals exist: focus is handed over in `_connectTile` (`focusOnConnect`). ⚠️ A divider drag reflows locally per frame and sends ONE resize per affected tile at pointer-up. ⚠️ The grid is CELLS (owner: an empty cell can be any cell): `grid.cells` (id or `null`) is the one source of truth, `grid.ids` a derived getter, never written; the shape still comes from the tile count, a shape change goes through `fitTileCells`, and the stored `ids` carry the cells with `null` holes. ⚠️ A tile moves (its header dragged or its tab dropped onto another tile or an empty cell, `Ctrl+Shift+Arrows`) ONLY through `_reorderTiles`: never a remount, reconnect or reload, and since sizes belong to the cells only a tile whose cell size changed fits; off while a tile is zoomed. The header drag carries its own type, never text, and is not `draggedTabId`; the header focuses on click, never on press, so a cancelled drag changes nothing. The arrow chords skip text fields. ⚠️ Sessions Run from this tab join the open grid (`_joinTileGridFromRun`, called from `_ensureCreatedSessionVisible`); sessions created elsewhere never do.

-**Terminal touch gestures: link taps and text selection**: on touch devices xterm's linkifier and SelectionService never see the gesture, so both are driven explicitly (terminal-ui.js). ⚠️ A tap activates the link under it through the SAME provider as the hover linkifier (`_terminalLinkAtPoint`), synchronously inside `touchend` (keeps the user gesture `window.open` needs) and BEFORE any mouse report; the caret's logical line (`_tapIsOnCaretLine`) and TUI-owned rows (`_isActionableMobileTerminalTap`) keep their meaning. ⚠️ Gate on the caret line, never on tap intent (a shell calls every tap `'input'`). ⚠️ Long-press selects via xterm's public `select()`; keep the three guards: suppress the compat mouse pair after `touchend`, the bounded focus guard + `contextmenu` suppression for the platform long-press, and no closing `terminal.focus()` on phones.

-**Auto Copy (copy-on-select)** (`autoCopySelection`, per-device, default OFF): a finished terminal selection lands on the clipboard with no keystroke. ⚠️ Copy at the END of a gesture, never in `onSelectionChange` (per-cell); it only arms `_autoCopyPending` and a document-level `mouseup` flushes. ⚠️ The flush must be SYNCHRONOUS in the handler (both clipboard paths need user activation); never defer it to a timer. ⚠️ Touch needs its own calls from `_endTouchSelectionGesture()`/`_selectTouchSelectionLine()` (no mouseup arrives). ⚠️ Unlike `copyTerminalSelection()`, never clear the selection or focus the terminal; restore prior focus. Guards are pure in `decideAutoCopy()` (constants.js, 1M-char cap, refused not truncated).

-**OSC 52 clipboard** (`_installOsc52Clipboard`, terminal-ui.js; main terminal + every `TerminalTile`): a program in the PTY (Claude Code's `/copy`, tmux yanks, vim) sets the browser clipboard with `ESC ] 52`. ⚠️ Writes only: a `52;?` read query is always refused, never answered. ⚠️ A replay must never copy: `chunkedTerminalWrite` strips every OSC 52 (`OSC52_STRIP_RE`, constants.js) because xterm parses after `_isLoadingBuffer` is cleared, so the flag alone does not hold; a tile gates on its own `_bufferLoading`, which does. ⚠️ One copy arrives up to three times (Claude's own OSC 52, `tmux load-buffer -w`, set-clipboard forwarding), so identical text within `OSC52_DEDUPE_MS` is dropped. ⚠️ Every tab on the session receives it; only the focused one opens the manual-copy fallback. ⚠️ Restore prior focus after `_copyText` (its execCommand fallback focuses a temp textarea). Tests: `test/terminal-osc52-clipboard.test.ts` (replays drive the real `chunkedTerminalWrite` over `@xterm/headless`).

-**Ctrl+V paste trap** (`image-input.js`): `Ctrl+V` routes through `_handleImagePaste()`, which focuses a hidden `contenteditable` trap and reads the clipboard from the paste event landing there; images upload and their paths are typed in, text goes through `terminal.paste()` so bracketed-paste markers survive. ⚠️ **The trap must consume exactly ONE paste event** (Firefox delivers two per keypress: the `execCommand('paste')` event and the keydown's default action); the one-shot flag lives on the trap, never on a browser check. ⚠️ Do not remove the `execCommand('paste')` call: on some mobile engines it is the only route into the trap, and the trap is the only place image blobs are read.

Inline/untracked Codex retains local history or the capability-gated paging fallback. Copilot has no version gate; a stale/false tracking flag falls back to PageUp/PageDown. Touch alone has one more branch (`_shouldForwardTouchToApp`): in any mode, a drag also forwards as SGR wheel reports while xterm ITSELF tracks the mouse with SGR encoding (an app in the pane asked for it; a tracking mode other than `x10` and `coreMouseService.activeEncoding === 'SGR'`, so DEFAULT, X10 and SGR-pixel apps fail closed), because xterm encodes a wheel there but the touch listeners consume the drag. ⚠️ `getClaudeCliVersion()` must never cache a FAILED probe. ⚠️ Hand-report clicks only while the CLI has mouse tracking on: `_shouldReportMouseToCli()` gates all three report sites on `cliMouseTracking` (from `_recordStrippedMouseMode()`, session.ts), or a plain shell prints the reports as literal text. ⚠️ A `TerminalTile` (grid tile, split Pane B) forwards the wheel as SGR reports, pages it and reports clicks through these SAME gates with itself as the target (its terminal, its session, never `activeSessionId`), and scrolls Shift+wheel itself (xterm makes it a horizontal no-op); never copy the mode lists into terminal-tile.js.

The work runs in a DETACHED `scripts/self-update.sh` writing `update-status.json`, polled across the restart; pure helpers in `src/web/self-update.ts`. ⚠️ Compose: the restart kills the script, so nothing may be appended after the `restarting` marker; the repo must stay a host bind mount over `/opt/codeman` and the image must keep devDependencies + toolchain. ⚠️ `evaluateEnvironmentGate()` refuses releases that change `server.Dockerfile`/`docker-compose.yaml` or add `.env.example` keys, re-evaluated on `POST /api/system/update`; unknowns fail OPEN, but the exit-to-restart needs `--restart-by-exit 1` (`CODEMAN_RESTART_BY_EXIT=1` only in the Compose file). ⚠️ Keep the agent CLIs in `server.Dockerfile` pinned. → [docs/docker-self-update.md](docs/docker-self-update.md), [architecture-invariants#self-update](docs/architecture-invariants.md#self-update)

Media extensions are single-sourced in `attachment-registry.ts`. ⚠️ **XLSX previews parse in the BROWSER**, never on the server; the admission limits that keep a hostile workbook from freezing the worker live in `src/web/CLAUDE.md` (Spreadsheet preview). → [architecture-invariants#file-path-links-terminal--response-viewer](docs/architecture-invariants.md#file-path-links-terminal--response-viewer)
 
 **Filesystem path picker** (Link Existing "Browse" + the mobile keyboard's `📁 Path` key): lazy one-directory browsing via `GET /api/filesystem/browse`, with `GET /api/filesystem/preview` for the tapped file. Inserts the path **without** Enter, so the prompt is never submitted; the sibling `⌫ All` key clears only the unsent prompt and must never send the agent's `/clear`. ⚠️ This is a **second file-serving surface and inherits neither the attachment confinement nor its ownership scoping** — it allowlists Home, `CASES_DIR`, `/mnt/d` and `CODEMAN_FILE_PICKER_ROOTS`, blocks sensitive trees, and rejects symlink escapes **after** `realpath`. ⚠️ The optional `sessionId` is an ownership boundary that must be `canAccessOwned`-checked by hand (it does not go through `findSessionOrFail`), and in multi-user mode a non-admin gets only their own `userSpacePath` as a root: per-user spaces live INSIDE `homedir()`, so a `Home` root exposes every other user's workspace. Previews go through the same global conversion limiter, and Markdown/TXT/JSON are served as inert `text/plain`. → [architecture-invariants#filesystem-path-picker](docs/architecture-invariants.md#filesystem-path-picker)
 
 **File Viewer edit mode** (issue #212): the file-preview overlay edits workspace text files in place — `GET .../file-content?edit=1` + `PUT /api/sessions/:id/file-content`, policy in `src/config/file-editing.ts`. This is a **third file surface and the only one that WRITES**: read-path confinement (realpath + workspace + ownership) plus sensitive/blocked/`.git` denies and an extension **allowlist**; writes are `wx`-temp + rename (no `O_CREAT` anywhere = edit-in-place is structural); optimistic concurrency via sha256 `baseHash` → 409. ⚠️ `edit=1` never truncates and the client must never save a plain-preview buffer (the 500-line truncation would silently delete the rest). ⚠️ CRLF/UTF-8 guards: EOL re-applied server-side, non-UTF-8 refused via round-trip compare. → [architecture-invariants#file-viewer-edit-mode](docs/architecture-invariants.md#file-viewer-edit-mode), `docs/file-viewer-edit-plan.md`
 
-**File Viewer text view: rendered markdown + Lines/Wrap toggles** (`_renderFilePreviewText()` in panels-ui.js): a `.md`/`.markdown` opens RENDERED by default with an `MD` pill back to source; the plain-text view has `Lines` (CSS-counter gutter) and `Wrap` toggles. ⚠️ ONE markdown pipeline: the viewer calls `_renderMarkdown(text, { breaks: false })` (marked + the DOMPurify allowlist, the Response Viewer's; chat keeps the default `breaks: true`, a file must not turn every hard wrap into a `<br>`) and binds the Response Viewer's click delegate (`_bindResponseViewerInteractions`) on the preview body for code-copy buttons and path links; never a second parser or handler. ⚠️ The document is built inside a `<template>` (a detached div with `innerHTML` set starts fetching every `<img src>` before the rewrite), then `_rebaseFilePreviewMarkdownRefs()` points relative images at the workspace-confined `file-raw` under the document's directory and root-relative ones under the workspace root (never a widened route; a failed load degrades to alt text), after `decodeURIComponent`ing the ref and dropping `?query`/`#fragment` (marked percent-encodes destinations, and the route encodes again), and turns workspace links into `a.rv-path` carrying `data-session-id` for the delegate (the linkifier's absolute paths get it too), stripping the `target` marked gave them. ⚠️ A preview opened by attachment id under a bare file name (attachment cards, history drawer: the registry keeps no relative path) has no directory, so its workspace refs degrade (images to alt text, links to their text), never resolve against the workspace root. ⚠️ The container carries `data-i18n-skip` or the translator rewrites the document's prose. ⚠️ Toggles are per-device localStorage keys (`codeman:filePreview*`), never `SettingsUpdateSchema`; Lines/Wrap are class flips on the ONE `<pre>`, with rules scoped `.file-preview-body > pre.file-preview-text` so they never leak into the document's code blocks. Markdown fetches `lines=10000` (the route ceiling), other text keeps 500. ⚠️ `md`/`markdown` are IN `FILE_PREVIEW_EXTENSIONS` (owner decision 2026-10-13): a markdown path clicked or tapped in the TERMINAL (main pane, grid tiles and split Pane B share `registerFilePathLinkProvider`) opens this rendered view like every other surface, never the streaming log viewer; other in-workspace text keeps the tail viewer (live follow). The terminal pattern links `.markdown` and `.htm` too.

 **Files panel search** (COD-236, the `q` param on `GET /api/sessions/:id/files`): `compileFileQuery()` (`utils/file-query.ts`, pure) compiles the query into a predicate the server-side walk prunes with; a query returns a FLAT match list and the walk recurses past non-matching directories. An empty, whitespace-only or overlong (`MAX_QUERY_LENGTH`, 256) query compiles to `null`, keeping the default tree response byte-identical. ⚠️ **Never compile a glob into a RegExp** (`*a*a*a…` backtracks and freezes the event loop for the whole server): `globMatch()` is a two-pointer wildcard walk. → [architecture-invariants#files-panel-search](docs/architecture-invariants.md#files-panel-search)
 
 **Git status indicator** (`showGitStatus`, per-device, default OFF; `src/git-workspace-status.ts`, `routes/git-status-routes.ts`, `git-status-ui.js`): the bottom-bar indicator and its panel read `GET /api/sessions/:id/git-status` and `/git-diff`, read-only and offline (it never fetches and never writes). ⚠️ git never runs on a repository at or inside a Docker case workspace (walk-up, scan and diff alike, and a cached repository list is re-checked against the CURRENT Docker roots), since a container could plant a clean filter that runs on the host; remote and Docker sessions answer `unsupported`. ⚠️ `git-diff` takes `repo`/`path`/`kind` only as keys matched against the workspace's own repository list (`findWorkspaceRepo()`) and that repository's current status, never as paths. ⚠️ Keep `--no-optional-locks`, `core.fsmonitor=false` and `log.showSignature=false` on every call and `--no-ext-diff --no-textconv` on diffs; clean filters still run, which is why the Docker rule exists. ⚠️ An enclosing repository at `$HOME` or above is ignored (`isUnrelatedAncestor()`), and is identified by one cached `rev-parse` before any full status runs. Everything git supplies renders via `textContent`. Tests: `test/git-workspace-status.test.ts`, `test/routes/git-status-routes.test.ts`, and `test/git-status.browser.test.ts` (browser suite, not in the gate).
 
 **Raw file bodies are streamed and range-aware**: `file-raw`, the attachments `/raw` route, `GET /api/download` and the rendered-HTML route `GET /html-view/<cap>/...` share `sendFileBody()`, advertise `Accept-Ranges: bytes` and answer `Range` with `206` + `Content-Range` (single-range, parser in `src/web/http-range.ts`); without it `<video>` cannot seek. The size cap (`MAX_FILE_DOWNLOAD_BYTES`, default 2GB, env `CODEMAN_MAX_DOWNLOAD_BYTES`, `0` = unlimited) is a sanity bound, not memory protection; never reintroduce a whole-file buffer. ⚠️ Bodies go out via `reply.hijack()`, so `sendRawStream` must copy the status onto `reply.raw` by hand or a partial body ships as `200`. ⚠️ Closing the preview must pause and unload media (`_stopFilePreviewMedia`), since a detached `HTMLMediaElement` keeps playing. → [architecture-invariants#raw-file-bodies-streamed-and-range-aware](docs/architecture-invariants.md#raw-file-bodies-streamed-and-range-aware)

It is **STANDALONE** and deliberately never imports or touches `subagent-watcher.ts`, despite reading the same tree.

Core in `src/git-clone.ts`. ⚠️ **The URL is a code-execution surface**: refuse every `::` form and a leading `-`, spawn only argv arrays with `--` before operands. ⚠️ Stay non-interactive (`gitNonInteractiveEnv()`) or the open request hangs; never collect credentials, refuse `user:password@` URLs. ⚠️ Timeout kills the process GROUP, remove the destination only if this attempt created it, and repo contents win over scaffolding (existing `CLAUDE.md` kept, hooks merged, repo `.claude/settings*` warned about). → [architecture-invariants#clone-a-repository-as-a-case](docs/architecture-invariants.md#clone-a-repository-as-a-case)

 **Cross-session search**: `GET /api/search` federates an in-memory search over session metadata, run-summary events, and attachment-history entries. The pure core `searchSources()` does substring matching with hard per-type caps: **no regex (so no ReDoS) and no filesystem reads (so no traversal)**. The server-private `externalPath` is never read. PAST sessions (#261) come from `session-history-index.ts`, a capped snapshot of the unified list filled **outside** the request path (`/api/sessions/unified` publishes it; a stale one is rebuilt fire-and-forget), that indirection is what keeps the no-fs property. ⚠️ The snapshot is stored UNSCOPED with a per-row owner and MUST be re-filtered through `canAccessOwned()` on read; history rows carry `jumpTo.kind:'resume-session'`, since a closed session has no tab to select. → [architecture-invariants#cross-session-search](docs/architecture-invariants.md#cross-session-search)
 
 **Web tabs** (dashboard URLs as tabs): a saved URL renders as a tab beside sessions, **NOT a `SessionMode`**, and is proxied through Codeman's own origin (`/webview/<cap>/...`). ⚠️ The proxy is NOT an API surface: its capability-based auth exemption stays fenced to safe methods and non-route paths (`test/webview-auth-exemption.test.ts`). ⚠️ Iframes omit `allow-same-origin` unless `trusted`, and `Authorization`/`codeman_session` are stripped upstream in both modes. ⚠️ **Egress guard**: link-local and cloud-metadata targets are refused at save time, by a sync hostname check at each connect (IP literals skip DNS), AND on the resolved address (`webview-egress.ts`); use the `undici` package's own `fetch` + `Agent`, never Node's global fetch. ⚠️ Loopback links in agent output auto-open as proxied web tabs (`openLinkThroughWebTabIfLoopback`), but never auto-route `*.localhost` (prompt-injectable DNS). Capabilities are revoked on logout (`revokeOwner`). → [architecture-invariants#web-tabs](docs/architecture-invariants.md#web-tabs), `docs/web-tabs.md`

-Frontend JS modules have `@fileoverview` with `@dependency`/`@loadorder` tags.

On the timer alone that character is not merely late, it is LOST: xterm emits the `\r` first and bumps the canonical counter past the candidate's snapshot, so the candidate stands down (measured, `hell\r` where the user typed `hello`). The edit-based diff described below is settled first at that keydown, so the drain decides with the evidence the timer had and Enter's textarea clear cannot turn the pending line into DELs. Ordering is pinned by `test/terminal-keycode229-recovery.browser.test.ts`, which the CI gate does NOT run. The same module replaces xterm's `_handleAnyTextareaChanges` (an append-only `newValue.replace(oldValue, '')` diff) with an edit-based one, so an Android autocorrect on space (delete + insert) reaches the PTY once instead of duplicating the line; ⚠️ that diff is settled at the NEXT keydown, before xterm handles that key, because xterm clears the textarea for Enter and a pending diff would then send one DEL per character ahead of the submitted line (except a composition xterm finalizes synchronously at that key, which stays xterm's). ⚠️ Every xterm that takes keyboard input wires its OWN controller from this module: the primary pane (terminal-ui.js `initTerminal()`) and each `TerminalTile` (terminal-tile.js `_createKeyCode229Recovery()`, so every grid tile and the split's Pane B, which a wide Android tablet reaches), each on its own textarea, composition helper and session; in both, `handleKeyEvent` must run ABOVE the custom key handler's keyCode-229 early return, and `notifyCanonicalData` sits in the onData lambda, never in the send path the recovered bytes also take. `mobile-ime-preview.js` (iOS WebKit only) paints the text an IME is composing: an iOS IME commit is routed into the local-echo overlay through the ordinary printable/paste branch and then `_transferMobileImeCommitToLocalEcho`, and without local echo the preview clears only on output parsed AFTER the commit (or its 2 s fallback). ⚠️ It watches keydown in the capture phase on `terminal.element`, never on the textarea, because xterm finalizes the composition and emits the commit in its own capture listener on the textarea.

-**Entrance animations** (`entrance-animations.js`, all OFF by default): opt-in animations for tabs, terminal, windows, connection lines and tile-grid tiles, chosen via `data-tab-anim` / `data-term-anim` / `data-win-anim` / `data-line-anim` / `data-tile-anim` on `<html>`; the default `legacy` theme short-circuits every hook (tiles keep the grid's own `settle`). ⚠️ Tabs and lines are destroyed mid-animation on re-render, so re-apply to the fresh element by id with a negative `animation-delay` (resume, never restart). ⚠️ Terminal-pane styles may animate only transform / opacity / clip-path (anything else resizes the PTY via FitAddon); `blur` is the ONE sanctioned `filter` exception, do not generalise it. ⚠️ Line glow lives in `--line-glow` so blur keyframes interpolate. Every animation setting lives in App Settings → **Animations** (`#settings-animations`); put new ones there. ⚠️ Tiles are OFF by default (Animations → Tile Animations, default `settle` = the grid's own fade, no screen beat); a theme only presets it. A tile's FRAME animates transform/opacity only (six at once, no filter) with `tile-enter*`/`tile-leave*` keyframe names (what the mount and the still copy listen for); its SCREEN replays the pane style on `.tile-body.term-enter`; a reload's restore always settles.

-**Mobile tab strip scrolling** (issue #257): under 768px the tab strip scrolls horizontally, so the active tab must be kept reachable. `_updateActiveTabImmediate()` reveals it via `computeTabScrollLeft()` (constants.js, rect math on the strip's own `scrollLeft`, never `scrollIntoView()`, which scrolls the document under the fixed header); `_fullRenderSessionTabs()` must restore `scrollLeft` across rebuilds and re-reveal only when the active tab changed (`_lastRenderedActiveTabId`) or, grouped by state, the ACTIVE tab moved to another state band (`_noteActiveTabBand()`, both render paths, scrolling row only; another tab's move never scrolls). ⚠️ The phone-block `min-width` on `.session-tab.active .tab-name` keeps the tab's centre off the gear/close icons, sized for numberless tabs 10+ (floor 40px); do not shrink it. ⚠️ Never reintroduce hoisting the active session to the front of the strip.

-**Session list layout: header strip or left sidebar** (`sessionListLayout`, default `header`; per-device via `displayKeys`, also in `SettingsUpdateSchema`): the list can move into a collapsible `<aside>` (Alt+B, `toggleSessionSidebar`) or, via `tabOrientation`, a resizable vertical `#tabRail` (desktop/tablet only). ⚠️ There is ONE `#sessionTabs`, MOVED between hosts, never a second list: `applySessionListLayout()` runs first, then `applyTabOrientation()`, both BEFORE `applyTabWrapSettings()`, and both arm/disarm `_startSidebarRichClock()`. ⚠️ Axis decisions use `_isVerticalTabList()`, never `isSessionSidebarActive()` alone. ⚠️ Rich rows share one gate, `isRichTabRows()`; rich CSS pairs sidebar+rail with comma-grouped selectors, never `:is()`, and card rules stay rail-scoped. ⚠️ Rail sort (`tabRailSort`, default `activity`) is the flex `order` property only, never a DOM reorder; the arrow-key walk alone follows computed `order`. ⚠️ Leaving sidebar mode clears `_sidebarFilter`; the handheld overlay drawer is `inert` when closed, the docked rail never. ⚠️ The rail's **Search sessions** box (`setTabRailSearch`, in memory only) and the sidebar filter share ONE row filter, `_applyTabListFilter()` over the pure `CodemanTabSearch` (constants.js): classes only, never a reorder or layout write; the rail matches the name, the sidebar name + folder. ⚠️ A session row with a tab alert (`tabAlerts`, red or yellow) is never hidden by either box: it goes in as `keep: true`, counts toward its group (which stays on screen) but not toward `matchCount`. ⚠️ Escape in the rail box is claimed by the global capture-phase Escape branch (the box's own `onkeydown` runs after it, too late to stop `closeAllPanels()`), and a filter change that shows or hides anything redraws the connector lines, since a keystroke re-renders nothing; a floating window finds its parent tab only through `_paintedSessionTab()` (a hidden row's rect is all zero but truthy, which drew connectors from the viewport's corner). While it runs `_projectTabGroups()` projects every group open (a collapsed group's rows are not in the DOM) and `toggleTabGroupCollapsed()` refuses, leaving the stored collapse untouched; drag stays on during a search (owner decision), a drop landing between the visible neighbours; `applyTabOrientation()` clears it off the rail.

-**Tab layouts** (`tabArrangement`, per-device, default `classic`; `state`/`case`/`ledger` are opt-in; Discussion #426): `state` (option C) splits the list into needs you / waiting / working / idle (idle is `quiet`: its heading stays as the row's anchor but draws no label; `tabStateOrder: 'urgent-last'` flips the order, needs you at the bottom): rows in the desktop header strip with left-aligned labels in a measured column (the brand sits over the strip's corner, so the rows after the first start under "Codeman"), sections in the flat rail and the sidebar, inline dividers on the tablet strip, group order with no headings on phones. `case` (option A) wraps each case's tabs in one `.tab-cluster` box and hides the `-<case>` of a generated name (`.tab-name-case`). `ledger` (option B) is a CSS-only grid on the desktop header strip. `classic` is the old strip. Pure cores: `CodemanTabTriage` and `CodemanTabClusters` (constants.js). ⚠️ `state` is the flex `order` property plus `aria-hidden` heading/break elements reconciled in place by `_syncTabTriageChrome()` after BOTH render paths, never a DOM reorder (a state change is an incremental pass). ⚠️ `case` boxes ARE a DOM grouping, so the incremental path rebuilds whenever `_tabClusterLayout().key` changes; membership follows `_mobileOverviewCaseFor()` like the home screens. ⚠️ Drag only reorders within a group or box (`_isTabDropAcrossGroups()`). ⚠️ Named groups in the vertical rail win over both groupings. ⚠️ `classic` must leave no trace (no headings, no inline order, no boxes, no name split), and the ledger must not change the markup.

-**Header stats styles** (`headerStatsStyle`, per-device, desktop only, default `compact`; Discussion #426 option G): `tiles` / `compact` (two pills, a ring beside every value) / `classic` (as before), keyed on `data-header-stats` (pre-paint + `applyHeaderStatsStyle()`), forced to `classic` below 768px and in a solo window. ⚠️ The clustered styles MOVE `#connectionIndicator` into `#headerSystemStats` and `#planUsageChip` right after it; `classic` moves them back to comment anchors. ⚠️ WS joins the pill only while System Stats is shown. ⚠️ The extra parts (stat rings, tile words, plan rings, meters) are always rendered and hidden by default in CSS, which is what keeps `classic` unchanged; tile words are derived beside the connection descriptor, never added to it (`test/connection-indicator.test.ts` pins its shape). ⚠️ A tile is a three-row grid (label, value, bar) with pixel line-heights and the bundled JetBrains Mono; never lay the bar over a fixed-height tile (a taller system mono put the value on top of it). The WS tile's grid lives on the inner `.connection-tile`, because JS writes the indicator's `display` inline.

PAST rows resume through the shared `resumeHistorySession()`. Status pills carry `data-i18n-skip`. → [architecture-invariants#phone-overview-home-screen](docs/architecture-invariants.md#phone-overview-home-screen)
-
-**Desktop home tab rail** (`home-sessions.js`, desktop only): the welcome overlay's left gutter carries the open tabs as a rail docked flush left, full height, in overview order, each row showing `created … · <state> <duration>` from `_mobileOverviewSince()`; state classification is reused from mobile-overview.js (so it loads after it). ⚠️ The number badge is the Alt+1..9 tab-strip index, never renumber it to row position. ⚠️ The width gate lives in two places that must stay equal: `HOME_SESSIONS_MIN_WIDTH` (1180) and a `max-width: 1179px` media query. ⚠️ `.home-sessions[hidden]` must re-assert `display: none`. ⚠️ Size all children in `em` off the one `clamp()` knob, never `rem`/px. Age stamps tick in place (`_tickHomeSessionsTimes()`), never by re-render. Test: `test/home-sessions.test.ts`. → [architecture-invariants#desktop-home-tab-rail](docs/architecture-invariants.md#desktop-home-tab-rail)
-
-**Home-screen session order** (`CodemanSessionOrder` in constants.js, pure): BOTH home screens (phone overview, desktop rail) must order rows through this ONE comparator. Rank `needs` → `error` → `waiting` → `working` → `idle` → `done`. ⚠️ The tiebreak flips: states a session is still IN sort oldest-first, states it has STOPPED sort newest-first. ⚠️ The running group keys off `lastSubmitAt`, never `lastActivityAt` (a working pane repaints constantly). ⚠️ A 0 stamp means unknown and sorts last within its state. Final tiebreak is `orderIndex`, so the list never shuffles. The tab strip itself is NOT sorted by this. Test: `test/session-overview-order.test.ts`. → [architecture-invariants#home-screen-session-order](docs/architecture-invariants.md#home-screen-session-order)
-
-**Welcome "Resume Conversation" list** (terminal-ui.js): `loadHistorySessions()` fetches once and caches the corpus on `_historyAll`/`_historyCases`; every subsequent view (filter box, sort select, expand, the periodic refresh in panels-ui.js) goes through `_renderHistoryList()`, so never append rows to `#historyList` directly or re-fetch to re-sort. ⚠️ The box height is **class-driven**: expanding the list without `.history-list.expanded` leaves the collapsed `max-height` in place and just deepens a scroll well, which is the bug #260 reported (35 sessions in a ~4-row box). ⚠️ The A–Z sort keys off `_historyRowLabel()`, the SAME string the row renders (`name || firstPrompt || path`), most rows are transcript-backed and have no session name, so sorting on `name` alone silently does nothing. ⚠️ A filter implies expansion, and `_renderSearch()` hides `#historyHeader` (title + controls) as one unit while a search is active. Tests: `test/history-list-controls.test.ts`.
-
-**Command palette + shortcut registry**: `Ctrl/Cmd/Alt+K` opens the session palette; shortcuts live in a rebindable registry (`DEFAULT_SHORTCUTS`/`getShortcutRegistry()`/`matchesShortcutEvent()` in app.js, overrides in `settings.shortcutOverrides`). ⚠️ Palette-chord keys must ALSO be swallowed in `attachCustomKeyEventHandler` (terminal-ui.js) or xterm writes the control byte into the PTY. ⚠️ The global Escape handler (app.js) calls EVERY close method on every Escape, in the capture phase, so a close method that does more than hide (the palette and Session Manager restore focus) must return early when its overlay is not open. ⚠️ `saveAppSettings()` rebuilds settings from the DOM, so keys edited elsewhere (`shortcutOverrides`, `showTokenCount`, `showCost`) need explicit `_prev` carry-over. ⚠️ **Smart copy (`Ctrl+C`)**: with no selection it must `return true` without `preventDefault()` or the interrupt is lost; keep `copyTerminalSelection` out of `SHORTCUT_ACTIONS`. The gate tests the CLEANED selection (`CodemanCopySelection.clean`: trailing padding, plus a LEADING margin only up to the width the CLI declares in `capabilities.transcriptGutter`, never one derived from the pane); the strip is not idempotent, so clean once and pass the RAW selection on, and leave Alt+drag column selections untouched. → [architecture-invariants#command-palette-and-shortcut-registry](docs/architecture-invariants.md#command-palette-and-shortcut-registry)
-
-**Per-device vs synced settings**: the `displayKeys` set in settings-ui.js is a **client-side merge policy**, not a wire filter. A display key seeds from the server only when localStorage has no value for it, which is what prevents one device overwriting another; `showPlanUsageLimits` is additionally `delete`d from the incoming payload outright. Separately, `SettingsUpdateSchema` is `.strict()` and simply **does not declare** `skin`, `showFileViewerButton`, `showCronButton`, `webglRendererEnabled`, `localEchoEnabled`, `cjkInputEnabled`, or `extendedKeyboardBar`, so sending one of those is a validation error. The rest (`showResponseViewer`, `showPlanUsageLimits`, `language`, and most `show*` keys) ARE in the schema and do persist server-side; they are per-device by client policy only. ⚠️ Adding a new per-device setting means deciding **both** questions: membership in `displayKeys`, and presence in the schema.
-
-**Settings surface** (`#appSettingsModal` + `#sessionOptionsModal` + `#createCaseModal`): one `set-*` language shared through a single `:is(...)` id scope in styles.css. App Settings' rail is a table of contents over ONE scrolling document (`switchSettingsTab` scrolls); Session Options and Add Case really switch (`switchOptionsTab` / `switchCaseModalTab`), and their larger per-modal size blocks are the design, not drift. ⚠️ **The load/save contract is `getElementById` by id**: renaming or dropping a control id silently stops it loading or saving. ⚠️ The Session Options "Session" entry still keys off `context` (label-only rename). ⚠️ Add Case keeps its legacy `.form-row` markup via an adapter; every `<details>` there needs `.set-adv-chev` plus both marker suppressions. ⚠️ Model cards and the effort segment are views over hidden `<select>`s, which stay the source of truth. ⚠️ `.modal-tabs*` classes are retired; `admin-ui.js` needs `.set-rail-items` + `.set-doc` to survive any restructure. Guard: `test/app-settings-structure.test.ts`. → [architecture-invariants#settings-surface-app-settings-session-options-add-case](docs/architecture-invariants.md#settings-surface-app-settings-session-options-add-case)
-
-**Header button visibility**: most header controls are opt-in and hidden by a marker class (`btn-multimonitor--hidden`, `btn-response-viewer-header--hidden`, `btn-file-viewer--hidden`, `btn-cron--hidden`, and the desktop-gated `btn-split--hidden` / `btn-tile-grid--hidden`, which also need a `@media (max-width: 1179px)` backstop) that `applyHeaderVisibilitySettings()` (settings-ui.js) toggles after settings load; the multi-monitor button is instead stripped at render by `renderIndexHtml`. ⚠️ Hiding must go through the marker class: the base rules are `display:inline-flex !important`, so an inline style cannot override them. Current desktop default is WS/CPU/MEM + File Viewer + Tiles (1180px and wider) + gear, with the token chip and lifecycle-log button OFF. ⚠️ New header controls must not leak onto phones; `test/mobile-header-buttons-policy.test.ts` is the static guard. → [architecture-invariants#header-button-visibility-multi-monitor-response-viewer-file-viewer-cron](docs/architecture-invariants.md#header-button-visibility-multi-monitor-response-viewer-file-viewer-cron)
+**Frontend invariants live in [`src/web/CLAUDE.md`](src/web/CLAUDE.md)**: module load-order notes and every `src/web/public/` UI subsystem (tab strip, sidebar, rail and tab layouts, tile grid, split pane, lineage lines, home screens, settings surface, skins and fonts, mobile keyboard/toolbar/composer, terminal touch, copy and paste, file-preview markdown, XLSX preview limits, z-index stack, connection-loss UI, SSE watchdog, keyboard shortcuts incl. the Ctrl+W owner decision). Claude Code loads it automatically when the Read tool opens a file under `src/web/`. ⚠️ Reading files through Bash (`cat`, `sed`, `grep`) does NOT load it, so **Read `src/web/CLAUDE.md` before editing anything in `src/web/public/`** if it is not already in context.
 
 **Gesture control** (camera hand-tracking overlay, opt-in, default OFF): `CODEMAN_GESTURE=1` makes the feature *available*; `gestureControlEnabled` turns it on. The bundle is injected by `renderIndexHtml` only when enabled, which is why that method is `async` and reads settings with `readSettings(true)` (a fresh read: a post-save reload lands inside the 2s cache TTL and would otherwise render the pre-toggle state). **Source lives in `packages/gesture-control/`; edit there, run `npm run build:gesture`, and commit the regenerated bundle** because dev serves the committed bundle with no runtime bundler. The MediaPipe wasm + model are fetched separately and gitignored. ⚠️ Keep `MP_VERSION` in `fetch-gesture-assets.mjs` in sync with `@mediapipe/tasks-vision`. → [architecture-invariants#gesture-control-the-source-package](docs/architecture-invariants.md#gesture-control-the-source-package)
 
-**Terminal font weight** (`terminalFontWeight` / `terminalFontWeightBold`, per-device, default = xterm's own `normal`/`bold`): Claude Code's markdown bold is a bare `ESC[1m`, so the weight step is its only cue. `CodemanTerminalFont.resolveWeights()` (constants.js, pure) resolves each slot against **its own** xterm default. ⚠️ The `@font-face` for `fonts/jetbrains-mono-variable.woff2` must stay declared `100 800` (the browser synthesizes from the descriptor, not the file); narrowing it silently makes the setting a no-op. ⚠️ A live save must reach both echo overlays (`refreshFont()`) and open Agent Teams panes. ⚠️ Leave `_awaitTerminalFont()` untouched. Test: `test/terminal-font-weight.test.ts`. → [architecture-invariants#terminal-font-weight](docs/architecture-invariants.md#terminal-font-weight)
-
-**Theme skins / branding / i18n**: `skin` selects a palette via `data-skin` on `<html>`, applied by an **inline pre-paint script** in `index.html` reading `localStorage['codeman:skin']` to avoid a flash of wrong theme. ⚠️ A skin is **four things that must stay in sync**, and missing any one degrades silently: the `html[data-skin="…"]` token block in `styles.css`, the xterm ANSI palette in `terminal-ui.js`, the pre-paint allowlist, and the Settings picker (both in `index.html`). `test/skin-themes.test.ts` is the static guard. Light skins additionally need `color-scheme: light` and xterm `minimumContrastRatio: 4.5`, and `applyTerminalSkin()` must call the local-echo overlay's `refreshFont()` because it caches the terminal fg/bg. `displayName` changes user-facing browser branding only and must NEVER rename npm package, CLI, API, storage, CSS, or protocol identifiers. `language` (`en`/`zh-CN`) keeps English as the canonical source so live switching stays reversible. User display names flow through `textContent`/attribute APIs and the server title's HTML escaper, never `innerHTML`. → [architecture-invariants#theme-skins](docs/architecture-invariants.md#theme-skins)
-
-**Foldable settings identity**: responsive layout is width-driven via `MobileDetection.getDeviceType()`, but the localStorage namespace uses `MobileDetection.isHandheldDevice()` so an unfolded Android foldable keeps `codeman-app-settings-mobile`. ⚠️ Do not switch per-device settings namespaces from instantaneous viewport width: a posture-triggered WebView reload would lose opt-in UI. Regression profile: `OPPO Find N5 (unfolded)` in `test/mobile/devices.ts`. → [architecture-invariants#foldable-settings-identity](docs/architecture-invariants.md#foldable-settings-identity)
-
-**Folding devices: a fold is not a keyboard, and dialogs avoid the hinge**: ⚠️ in `handleViewportResize()`, a visual-viewport resize that changes the WIDTH is a shape change (rotation, fold) and must never be read as the keyboard; it re-baselines instead, or `keyboardVisible` latches with no keyboard. ⚠️ `init()` must seed `lastViewportWidth`. ⚠️ With the keyboard up, a shape change baselines to `window.innerHeight`, never the shrunk visual height. ⚠️ The hinge is reserved via `--fold-inline-end`/`--fold-block-end` (0px when unfolded): each overlay fold rule must re-state its own gutter, a base gutter overridden by a later `@media` block needs its own fold restatement there on a zero base, and dialogs use physical sides (left/top segment) in every language. Guard: `test/foldable-layout.test.ts`. → [architecture-invariants#folding-devices](docs/architecture-invariants.md#folding-devices)
-
-**WebGL renderer toggle** (`webglRendererEnabled`, per-device): the GPU-stall watchdog's sticky `codeman-webgl-disabled` marker survives page loads and is cleared only by an explicit OFF→ON save or `?webgl=force`. `?nowebgl` forces the DOM renderer per-load. → [architecture-invariants#webgl-renderer-toggle](docs/architecture-invariants.md#webgl-renderer-toggle)
-
-**Shell keyboard accessory bar + one-shot Ctrl** (`keyboard-accessory.js`): a shell-mode session swaps the mobile accessory bar for terminal controls; `setMode()` records `extendedKeyboardBar` as the base layout and `refreshForActiveSession()` resolves base-vs-shell. ⚠️ Ctrl is a one-shot modifier applied in `terminal.onData` (after `shouldSuppressTerminalQueryResponse`, before every send path), and must skip `isTerminalFocusOrMouseReport()` chunks. ⚠️ It must disarm on use, second tap, any other accessory key, session switch, keyboard dismissal and layout swap. ⚠️ `_handleCjkInput()` must apply it too (the CJK textarea bypasses onData). Mapping: `ctrlByteFor()`. ⚠️ mobile.css's light-skin repaint must keep excluding `.accessory-btn:not(.armed)` or the armed state is invisible. → [architecture-invariants#shell-keyboard-accessory-bar-and-one-shot-ctrl](docs/architecture-invariants.md#shell-keyboard-accessory-bar-and-one-shot-ctrl)
-
-**Mobile prompt composer** (`keyboard-accessory.js`): the agent bars' Paste key is **Compose**, a native multiline dialog where only **Send** submits (the shell bar keeps plain Paste). Opening it adopts the whole terminal prompt (`_takePendingLocalEcho`), erasing the flushed prefix with backspaces counted in code points. ⚠️ Drafts are per-session and in memory only (`_composerDrafts`), never persisted (prompts carry secrets). ⚠️ Delivery is a hand-built bracketed-paste frame via `_sendInputAsync` WITHOUT `useMux`, then a separate delayed Enter WITH it; never `terminal.paste()`, and the frame must never take the mux fallback (it strips newlines). ⚠️ `_composerMaxLength` must stay derived from `MAX_INPUT_LENGTH` minus the markers, or an oversized frame wedges the durable queue. ⚠️ The composer overlay needs its own gutter restatement after the fold rules. Test: `test/mobile-prompt-composer.test.ts`. → [architecture-invariants#mobile-prompt-composer](docs/architecture-invariants.md#mobile-prompt-composer)
-
 **PTY and browser terminal geometry** (#464): a browser terminal whose width differs from the PTY's garbles Claude's redraws, so `syncTerminalGeometry()` (terminal-ui.js) is the ONE function that may resize the main terminal (never a bare `fitAddon.fit()`), a font change is a geometry change, and the fit is withheld wherever the SIGWINCH is. ⚠️ Resize is answered with `Session.ptyGeometry`, and a client adopts its COLUMNS only (never rows); `ptyGeometry` is null without a live pane. → [architecture-invariants#pty-and-browser-terminal-geometry](docs/architecture-invariants.md#pty-and-browser-terminal-geometry)
 
-**Terminal resilience**: a replay clear is the queued in-stream `\x1bc` in `_resetTerminalForReplay()`, never `reset()`/`clear()` (queued bytes fuse into the snapshot); the renderer watchdog `_kickRenderer()` reads xterm privates, pinned by `test/xterm-private-api.test.ts` against the resolved lockfile version; every terminal capture fetch has a deadline that covers the BODY (`_fetchTerminalCapture`). → [architecture-invariants#terminal-resilience-replay-clears-renderer-liveness-fetch-deadlines](docs/architecture-invariants.md#terminal-resilience-replay-clears-renderer-liveness-fetch-deadlines)
-
-**WebSocket output-gap reconcile** (`_wsOutputGapSession`, app.js): output frames carry no sequence number, so an unintentional WS close while SSE stays up marks the session and the next open reconciles. ⚠️ The marker is cleared only once a repaint actually happened (`_markTerminalBufferReconciled()`, never in a `finally`). → [architecture-invariants#websocket-output-gap-reconcile](docs/architecture-invariants.md#websocket-output-gap-reconcile)
-
 **Service worker precache** (`sw.js` + `scripts/build.mjs`): `BUILD_ID` and `HASHED_ASSETS` are build-generated and the build THROWS unless each declaration appears exactly once; `caches.match` must pass `ignoreSearch: true` because `cacheBustAssets` appends `?v=` to hashed names. → [architecture-invariants#service-worker-precache-and-cache-key](docs/architecture-invariants.md#service-worker-precache-and-cache-key)
 
-**Dismissing the on-screen keyboard** (`terminal-ui.js`): two gestures blur the terminal's hidden textarea. (1) `_installMobileKeyboardDismiss()`, a document `touchend` that must never fire inside `#terminalContainer` or on a control (`MOBILE_KEYBOARD_DISMISS_EXEMPT_SELECTOR`, via `closest()`; roving-tabindex items sit at `tabindex=-1`, so the grouped rail's are listed as `[role="treeitem"]`). (2) In `_handleMobileTerminalTap`, a second tap on inert `content` blurs; the prompt row keeps focus-then-position. ⚠️ A scroll also ends in `touchend`: both classifiers must share one threshold (`TAP_THRESHOLD` reads `MOBILE_KEYBOARD_DISMISS_TAP_SLOP`), and multi-touch is never a tap. ⚠️ CI cannot see the only test for (1): run `npm run test:mobile -- test/mobile/keyboard.test.ts` by hand and diff the FAIL list against master. → [architecture-invariants#dismissing-the-on-screen-keyboard](docs/architecture-invariants.md#dismissing-the-on-screen-keyboard)
-
-**Phone toolbar: Enter replaces Shell** (post-1.8.0): inside `@media (max-width: 599px)` `btn-shell` is `display:none` and `btn-enter` takes its slot (`order: 4`); starting a shell moved into the Run dropdown (`Terminal / Shell` → `setRunMode('shell')` → `run()` → `runShell()`, button label "Run SH"). `runMode` is `z.string().max(20)` server-side, so new modes need no schema change. Desktop and tablet keep the green Run Shell button unchanged.
-
-⚠️ **`sendEnterKey()` MUST go through `terminal._core.coreService.triggerDataEvent('\r', true)`** — not `sendInput()`, and never a raw POST to `/api/sessions/:id/input`. `localEchoEnabled` defaults to `MobileDetection.isTouchDevice()`, so on every phone the characters you type are buffered in the `LocalEchoOverlay` and have **never reached the PTY**; the `onData` Enter branch in terminal-ui.js is what flushes `pendingText` first and only then sends `\r` (after an 80ms delay so text lands first). Sending a bare `\r` submits an empty line and strands the typed text on screen, so the button looks dead. Replaying the keypress reuses the overlay flush, the flushed-offset cleanup and the ordering instead of reimplementing them. `KeyboardAccessory.sendKey()` is for escape sequences (arrows/Esc) and is the WRONG template to copy for input.
-
-⚠️ **Skin overrides outrank plain class rules.** `styles.css` nests its skin block inside `html:not([data-skin="og"]) { … }`, so a bare `.btn-toolbar` rule in there resolves to specificity **(0,2,1)** and beats a `.btn-toolbar.btn-x` rule **(0,2,0)** in `mobile.css` regardless of load order. Toolbar-button colors set from mobile.css therefore need `!important` — that is why mobile.css leans on it so heavily. Symptom: only your `!important` properties land and everything else silently renders in generic toolbar grey.
-
-**Connection-loss UI** (`computeConnectionLossUi()` in constants.js, writer `_updateConnectionLossUi()` in app.js): the service worker serves the cached app shell, so an unreachable server (phone off the tailnet, VPN down, server stopped) used to render a normal-looking empty dashboard whose only tell was the 8px header dot, which reads as "no sessions", not "no connection". Two surfaces now: a full-screen **overlay** while no server state has loaded this page load (nothing behind it is worth preserving), and a non-blocking **banner** once it has (the terminal scrollback stays readable). ⚠️ A **2.5s grace** is load-bearing: a COM deploy restarts the server and SSE is back in ~200ms, and a banner on every deploy trains the user to ignore it. `navigator.onLine === false` skips the grace, since that is never a blip. Retry re-arms SSE **and** the terminal WS (`planWsReconnect` can 'give-up', and the SSE backoff caps at 30s).
-
-**SSE staleness watchdog** (`computeSseStale()` in constants.js, `_checkSseStale()` + a 5s interval in app.js): an `EventSource` can stop delivering without erroring, so the client forces a reconnect when nothing arrives. ⚠️ The server keepalive must stay the named `sse:heartbeat` event (`cleanupDeadClients()`, sse-stream-manager.ts), never an SSE comment, which `EventSource` cannot observe; its no-op client listener must stay registered. ⚠️ Judge staleness only while `connected` and online (the loop breaker). ⚠️ The liveness stamp lives inside `addListener`. ⚠️ Clear the interval only at the top of `connectSSE()`, or intervals stack. → [architecture-invariants#sse-staleness-watchdog](docs/architecture-invariants.md#sse-staleness-watchdog)
-
-**Z-index layers** (keep new overlays consistent with this stack): local echo overlay (7; with local echo on it also draws the iOS IME composition preview, as an underlined tail after its pending text via `setComposition`), iOS IME composition preview span when local echo is off (6 inside `.xterm-helpers`, whose own z-index 5 is its EFFECTIVE layer, so it sits UNDER the overlay and must never be used while the overlay shows text), terminal touch-selection bar (900, below floating agent windows), subagent windows + split picker menu + Tiles count menu (1000), plan agents (1100), mobile/tablet fixed header (1200), modals on ≤768px (1300, must beat the fixed header), log viewers (2000), connection-loss overlay (2500), image popups (3000), response viewer (5000, backdrop 4999), folder grid (5090, above the response viewer it opens from, below the file preview its tiles open), file-preview overlay (5100, must outrank the response viewer that launches it), toasts/path picker (10000+), custom-model center-status banner (10001; its `[hidden]` must re-assert `display: none` or `dismiss()` leaves an invisible click-blocker), custom-model swap-confirm/context-warning modals (10010). → [architecture-invariants#z-index-layers](docs/architecture-invariants.md#z-index-layers)

-
-**Keyboard shortcuts**: Escape (close), Ctrl+? (shortcut overlay), Ctrl/Cmd/Alt+K (session palette), Ctrl+Tab (next), Alt+[/] (prev/next tab), Alt+1-9 (switch tab), Ctrl+Shift+{/} (move tab left/right), Shift+Enter or Ctrl+Enter (newline), Ctrl+C (copy selection, else interrupt) / Ctrl+Shift+C (copy, never interrupts), Ctrl+L (clear), Ctrl+Shift+R (restore size), Ctrl+Shift+V (voice input), Ctrl/Cmd +/- (font), Shift+Wheel (local scrollback when mouse passthrough is active), Shift+drag (start a selection in a stripped-DECSET pane, where xterm's own Shift branch is unreachable and a Shift+drag used to select nothing; `_installShiftDragSelection`), right-click (copy the selection, the mintty/PuTTY convention, since xterm paints into a canvas and the native menu has no Copy for it; with nothing selected the native menu is left alone). Rebindable via the registry. ⚠️ **Ctrl+W is deliberately NOT bound** (owner decision): it is delete-word in every shell and agent CLI, and as Close Session it killed sessions with no confirm; `close-session` keeps `bindings: []` and stays bindable (`test/ctrl-w-never-closes.test.ts`).

Per-device keys go in the `displayKeys` set in settings-ui.js and must NOT be added to `SettingsUpdateSchema` (it is `.strict()`). ⚠️ Anything in `PUT /api/settings` that acts on a setting (the `toggleService` watcher calls) must resolve from **`merged`** (persisted + incoming), never from the raw request body: a partial PUT omits keys it doesn't intend to change, and `body.x ?? default` turns every omission into "apply the default" and silently resets live services. Pinned by `test/routes/system-routes-settings-partial-put.test.ts`. ⚠️ A synced setting is admin-only to write in multi-user mode (the PUT 403s a non-admin, whose browser does not send it): a new route that writes `settings.json` takes the same `isMultiUserMode() && !requireAdmin(req, reply)` gate.
 - **Hook event**: Add to `HookEventType`, add hook in `hooks-config.ts:generateHooksConfig()`, update `HookEventSchema`
 - **Mobile feature**: Add to relevant singleton, guard with `MobileDetection.isMobile()`. New header buttons must stay off phones (`test/mobile-header-buttons-policy.test.ts`).
 - **New test**: a test that constructs `WebServer` itself binds port 0 (`new WebServer(0, …)`, then `server.boundPort`), and a raw `http`/`net`/Fastify/`ws` server listens on `0` and reads `address().port`; mobile tests get theirs from `createTestServer()` and read `boundPort` too. `test/test-ports-guard.test.ts` refuses a fixed port in either. Route tests use `app.inject()` (no port needed); see `test/routes/_route-test-utils.ts`.

The browser suite (not mobile or perf) also runs nightly in `.github/workflows/browser-suite.yml`, which catches a regression after it lands, not before.
 
 ⚠️ **A file filter must match the runner.** `npm test -- test/mobile/keyboard.test.ts` matches nothing and exits GREEN having run zero tests, because the gate's config excludes that path — an excluded file needs its own runner (`npm run test:mobile -- <file>`, `npm run test:browser -- <file>`, `npm run test:perf -- <file>`). Vitest treats "no files matched a filter" as success, so read the file count, not just the colour.
 
-Raw `npx vitest` skips the config (and with it `setup.ts`); always use `npm test --` or pass `--config`.
+A raw `npx vitest` used to find no config, so `setup.ts` never ran and the suite wrote fixtures into the REAL `~/.codeman` (a `clis.json` with a test entry, `users.json`, `webhook.json`, `.env`, settings values: it looks exactly like "my settings were reset"). The root `vitest.config.ts` now re-exports `config/vitest.ci.config.ts`, so a bare run is isolated too, and `test/test-env-isolation.test.ts` pins that. Still prefer `npm test --`, and pass `--config config/vitest.config.ts` (or the browser/mobile/perf configs) deliberately for the suites the gate leaves out.
 
 **Config**: Vitest with `globals: true`, `fileParallelism: false`. Timeout 30s, teardown 60s. `config/vitest.config.ts` is the everything-config behind `test:all`; `config/vitest.ci.config.ts` is the gate and derives its excludes from `config/test-suites.ts`, which is also what `vitest.browser.config.ts` and `vitest.perf.config.ts` derive their includes from — so the exclusions and the runners cannot drift apart. Keep shared options in sync across them.
 
-**Tmux safety**: under vitest (`VITEST`), `TmuxManager` no-ops ALL shell commands (`IS_TEST_MODE` in `src/tmux-manager.ts`), docker IO is no-op'd likewise, and `Session` spawns an echo PTY (`TEST_PTY_SCRIPT`) instead of attaching tmux. `test/setup.ts` gives each file a temp `HOME`/`USERPROFILE` and strips `CODEMAN_PASSWORD`/`CODEMAN_USERNAME`, `CODEMAN_GESTURE` and `CODEMAN_INSTANCE`/`CODEMAN_DATA_DIR`/`CODEMAN_TMUX_SOCKET` (pinned by `test/test-env-isolation.test.ts`). ⚠️ `CODEMAN_DATA_DIR` overrides the temp HOME, so never drop its strip; strip `CODEMAN_INSTANCE` in the setup file, never in a hook (captured at first import). ⚠️ Delete case trees only via `safeRmHomeTree()`. ⚠️ Raw `npx vitest` without `--config` skips `setup.ts` and its isolation. → [architecture-invariants#test-isolation-tmux-docker-and-home](docs/architecture-invariants.md#test-isolation-tmux-docker-and-home)

 **Ports**: every in-process test server binds port 0 (the one exception, `test/codex-predictive-echo.test.ts`, starts a separate lab server process on 3222). A test that constructs `WebServer` reads `server.boundPort` (mobile tests: `createTestServer()`, then `server.boundPort`); a raw `http`/`net`/Fastify/`ws` server listens on `0` and reads `address().port`. `test/test-ports-guard.test.ts` fails a `WebServer` built on any other port and a raw `listen` on a number or `…PORT` constant. A test that needs a port nothing listens on binds 0, reads it and closes (`closedPort()` in `test/daemon-control.test.ts`), never "the server's port + 1". Never 3000 (the live instance).

+- **Opens what matters**: with no grid arranged yet, it fills the tiles with the sessions that are working first, then the ones waiting on you, then the most recently used, and always includes the one you are on.
+- **Keeps your layout**: once you arrange a grid (which session sits where, empty cells, tile count, divider sizes, the focused and zoomed tile), the Tiles button brings it back exactly, and so does a page reload while it was open.
+- **Tile animations** _(opt-in)_: **App Settings → Animations → Tile Animations** makes the grid open with a show: **CRT** (each tile switches on as a hot line, as in the GIF at the top), **Fly from tab**, **Deal**, **Beam down**, **Cascade**, **Pop** or **Soft**. Nothing moves under reduced motion.
+- **Scrolls like the main terminal**: the mouse wheel scrolls a fullscreen Claude conversation inside its tile, a Codex tile pages its transcript, and `Shift+wheel` scrolls the tile's local history.
+- **Detach Tiles** _(beta, opt-in)_: with **App Settings → Appearance → Detach Tiles** on, drag a tile's header out of the browser and it pops out into its own window; drop it on another Codeman window's tiles and it moves there.
+- **Hands-free**: with the [gesture overlay](#more-features) on, pinch a tile and carry it onto another tile to swap them, onto an empty cell to move it, or carry a tab onto the grid to add it.

 - **Git status in the bottom bar** — off by default (**App Settings → Header & Panels → Bottom bar → Git status**, per device). A small indicator at the right of the bottom bar shows the active session's repository at a glance: `● 3` uncommitted files, `↑ 2` commits not pushed, `⚠` merge conflicts, `✓` all committed and pushed. Click it for a draggable window listing the staged, not-staged, untracked and conflicted files (grouped under collapsed folders, or as a flat list if you turn that setting off) and the unpushed commits; **click a file to see its diff** (new files as all additions, deleted files as all removals), with **Open file** to jump to the viewer. A folder that holds several projects gets one collapsible section per repository found up to two levels down, all collapsed until you open them. Read-only and offline (Codeman never fetches or changes the repo); not shown for Docker or remote sessions.
 - **Clone a GitHub repo as a case** — paste a repository URL into **Add Case → Clone Repo** and Codeman clones it into `~/codeman-cases/<name>` and registers it as a normal case, ready to run an agent in. It preflights the URL while you type (tells you whether it can be cloned anonymously and offers the repo's real branches and tags for the optional branch/tag field), fills the case name in from the URL, and lets you pick which CLI the Run button should use. Public repositories over `https://`; Codeman never collects or stores credentials
 - **Create a case in a custom folder** — tick **Create in a custom folder** in **Add Case → Create New**, pick a parent folder (Browse included) and a name, and Codeman scaffolds the new case there instead of `~/codeman-cases`. The target must be a new or empty folder; system directories, your home folder itself, credential trees such as `~/.ssh`, and Codeman's own data folder are refused. Admin only in multi-user mode.

 - **Custom model endpoints** _(new in 1.29.0, HTTP API for now)_ — point a session's CLI at any OpenAI-compatible endpoint instead of its native backend: a local llama.cpp, llama-swap, Ollama or vLLM box, or a cloud gateway such as Azure AI Foundry or OpenRouter. Save an endpoint once (`POST /api/model-endpoints`; its models are discovered from `/v1/models`), apply it to a session (`POST /api/sessions/:id/custom-model`), and the CLI restarts in place on that endpoint. Verified live for Claude, OpenCode, Pi, Grok and OMP; Codex, Gemini and DeepSeek have documented gaps, Antigravity has no mechanism. A toolbar picker is the follow-up. See [`docs/custom-model-endpoints.md`](docs/custom-model-endpoints.md)
 - **Web tabs** — open Grafana, Uptime Kuma, a Vite dev server or any dashboard URL as a tab beside your sessions (Run dropdown → **Web / URL** → **Add URL**). Dashboards are proxied through Codeman's own origin, so an `http://` target works from a phone over HTTPS and through the tunnel, single-page apps route on their own paths, and a frame that reloads recovers itself. A `localhost` link an agent prints opens as a web tab automatically. See [`docs/web-tabs.md`](docs/web-tabs.md)
 - **Docker sessions** — run a case inside an isolated, hardened container. One checkbox on **Create New** spins up a container with sensible defaults and starts the agent inside it; multiple sessions share one per-case container, or attach a case to a container you already run; export a container + its workspace to a portable `.tar.gz` to move it to another machine.

+- **HTML reports open as pages**: click an `.html` path an agent printed (a test report, a coverage page, a dashboard) and the File Viewer shows it as a real page, with the scripts, styles, images and data files from its folder; the **Page** pill switches to the source and its Edit button. The page runs sandboxed with an opaque origin, so it cannot read Codeman's cookies, call Codeman's API or read files outside its own folder. Network access stays open, so a dashboard that loads Chart.js or fonts from a CDN works as it would from disk. Broad folders (`/`, your home, `/tmp`) are refused, so give a report a folder of its own. A `.md` path clicked in the terminal opens rendered too
+- **Clickable paths and the folder grid**: paths written as `~/…`, relative to the session folder, or broken across terminal lines are clickable in the terminal and the Response Viewer, and so are folders: a folder opens a grid of its files (renders, screenshots, reports) that you page through with the arrow keys
+- **OSC 52 clipboard**: a program in a session that sets the clipboard with OSC 52 (Claude Code's `/copy`, a tmux yank, vim) puts the text on your browser's clipboard, in the main terminal and in every tile. Clipboard read requests are refused, and replaying a buffer never copies

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

+该脚本会在缺失时自动安装 Node.js、tmux 和一套构建工具链（node-pty 没有 Linux 预编译包，需要从源码编译），把 Codeman 克隆到 `~/.codeman/app` 并完成构建。它会先看看机器上已有什么，最多问三个问题，然后无人值守地完成所有工作，最后给出访问 URL 和一个供手机扫描的二维码。几点须知：
 
-- **先询问，后改动。** 所有系统级改动（安装软件包、下载 AI CLI）都会先征求确认；结束时的菜单可选择：直接在本终端运行、安装为后台服务（systemd/launchd，开机自启），或暂不启动。不选就不会有任何后台进程。
-- **怎么访问，由你决定。** 安装器提供三种到达仪表盘的方式：**Tailscale**（环回绑定，由 `tailscale serve` 代理，得到带真实证书的 `https://<机器名>.<tailnet>.ts.net`，用你的 tailnet 当登录，无需密码）、**局域网内任意设备**（`0.0.0.0`，会提示设置一个强烈推荐的密码），或**仅本机**（`127.0.0.1`，最安全）。绑定网络却跳过密码需要显式确认，并以醒目警告收尾。高亮的默认项反映机器上已有的状态（已在用 Tailscale 时默认 Tailscale，重跑时沿用现有绑定），直接回车绝不会引入新软件。手动运行的 `codeman web` 仍默认仅环回。
-- **重跑即更新。** 再次运行同一条命令即可原地更新已完成的安装：`~/.codeman/app` 中的本地改动会被 stash（绝不丢弃），运行中的服务会自动重启并校验。若首次安装中途失败，重跑会继续完成完整的安装流程。也可以使用 `install.sh update` 与 `install.sh uninstall`。
-- **CI / 无终端环境：** 没有终端时，涉及系统改动的步骤会带着说明中止，而不是静默执行；在自动化场景设置 `CODEMAN_NONINTERACTIVE=1` 即可批准这些步骤。
+- **三个问题，全部在开头问完。** 仪表盘怎么访问、（可选）这台机器在你的 tailnet 里叫什么，以及是否把 Codeman 作为后台服务运行（systemd/launchd，开机自启；直接回车即为「是」）。所有需要你出面的事，包括对所有缺失软件包的一次性同意、一次 sudo 密码和 Tailscale 登录，都在构建之前完成，所以编译期间你可以走开。
+- **怎么访问，由你决定。** 安装器提供三种到达仪表盘的方式：**Tailscale**（环回绑定，由 `tailscale serve` 代理，得到带真实证书的 `https://<机器名>.<tailnet>.ts.net`，用你的 tailnet 当登录，无需密码）、**局域网内任意设备**（`0.0.0.0`，会提示设置一个强烈推荐的密码），或**仅本机**（`127.0.0.1`，最安全）。绑定网络却跳过密码需要显式确认，并以醒目警告收尾。高亮的默认项反映机器上已有的状态（已在用 Tailscale 时默认 Tailscale，重跑时沿用现有绑定），直接回车绝不会引入新软件。如果你节点上的 `:443` 已被别的应用占用，Codeman 会改用 `https://<机器名>.<tailnet>.ts.net/codeman` 或第二个端口，而不是把它替换掉。手动运行的 `codeman web` 仍默认仅环回。
+- **名字由你来定。** 默认情况下，URL 用的是这台机器在 tailnet 里现有的名字。第二个问题答「是」会把机器改名为 `codeman-<hostname>`（这也会改掉它在 SSH 里的名字，所以默认是「否」）；之后也可以用 `install.sh name` 来改。
+- **重跑即更新。** 再次运行同一条命令即可原地更新已完成的安装：`~/.codeman/app` 中的本地改动会被 stash（绝不丢弃），运行中的服务会自动重启并校验。若首次安装中途失败，重跑会继续完成完整的安装流程。`install.sh status` 会再次打印 URL 和二维码；另外还有 `install.sh update`、`install.sh tailscale` 和 `install.sh uninstall`。
+- **给急性子的参数。** `curl -fsSL https://getcodeman.com/install | bash -s -- --tailscale --service` 直接在命令行上回答这些问题（还有 `--lan`、`--local`、`--run`、`--no-start`、`--name <n>`、`--port <n>`、`--yes`）。**CI / 无终端环境：** 没有终端时，涉及系统改动的步骤会带着说明中止，而不是静默执行；在自动化场景设置 `CODEMAN_NONINTERACTIVE=1` 即可批准这些步骤。

 - **Web 标签页** —— 把 Grafana、Uptime Kuma、一个 Vite 开发服务器或任何仪表盘 URL 作为标签页打开在会话旁边（Run 下拉菜单 → **Web / URL** → **Add URL**）。仪表盘通过 Codeman 自己的源代理，因此 `http://` 目标在手机上走 HTTPS 也能用、走隧道也能用；单页应用能在自己的路径上正常路由，页面自己重载后也能自行恢复。智能体打印出的 `localhost` 链接会自动以 Web 标签页打开。详见 [`docs/web-tabs.md`](docs/web-tabs.md)

 ### 行路规则（POST 之前先读）
 
-1. **只发单行输入，而且必须以 `\r` 结尾。** 编程输入按字面文本发送，**只有当输入里含回车符时才会触发 Enter**：`{"input":"run tests\r"}`。少了 `\r`，文本就停在会话的输入框里不被提交（同一次调用里的 `wait` 还会在一个压根没开始的回合上耗满整个超时）。内嵌的换行会被剥掉而不是报错，因此 `"echo A\necho B\r"` 执行的是拼起来的 `echo Aecho B`：一次调用只发一行。
+1. **输入必须以 `\r` 结尾。** 编程输入按字面文本发送，**只有当输入里含回车符时才会触发 Enter**：`{"input":"run tests\r"}`。少了 `\r`，文本就停在会话的输入框里不被提交（同一次调用里的 `wait` 还会在一个压根没开始的回合上耗满整个超时）。使用 `useMux` 时内嵌的换行会保留，各行作为一次粘贴送入，因此 `"echo A\necho B\r"` 在 shell 里会执行两条命令；但重新按下滞留 Enter 的检查无法可靠识别多行粘贴，所以较长的多行内容最好写进文件，让 agent 自己去读。
 2. **让输入幂等。** 在 `POST …/input` 上带上稳定的 `clientId` 和按会话单调递增的 `seq`。服务端会去重，因此连接中断后的重试不会重复投递提示。
 3. **认证。** 若设置了 `CODEMAN_PASSWORD`，发送 HTTP Basic 认证（用户 `admin` 或 `CODEMAN_USERNAME`）或 `codeman_session` cookie。默认的环回安装无密码。缺失的 `Origin` 头被允许，因此普通 `curl` 可用；跨站的浏览器 origin 会被拒绝（CSRF 防护）。⚠️ `401` 回的是裸字符串 `Unauthorized`，**不是** JSON 信封，直接喂给 `jq` 只会抛解析错误而看不到真正的失败原因：先看状态码，再解析。
 4. **响应信封。** 多数端点返回 `{ "success": true, "data": … }`（错误：`{ "success": false, "error", "errorCode" }`）。少数遗留 GET 返回裸响应体 —— **两种都要处理**（`body.data ?? body`）。
 5. **`/api/v1/*`** 是 `/api/*` 的稳定别名。
 6. **用等待代替轮询，别把超时当成错误。** 等待类端点在没等到事情发生时也以 HTTP `200` 加 `wait.timedOut: true` 应答，所以要循环调用短等待（默认 60 秒），而不是发一个超长的调用：隧道会掐断空闲连接。`wait.timeoutMs` 告诉你服务端钳制之后真正采用的超时（上限 600 秒）。
-7. **只有 `claude` 与 `deepseek` 会话会发出 `stop` 与 `blocked`。** 这两个来自 hook（Claude Code 自己的，以及 DeepSeek Harness 的状态桥接）；`shell` 与其他外部 CLI（opencode/codex/gemini/antigravity/pi/grok/omp）只接受 `idle`、`working` 与 `exit`。在这些模式上显式索要 `stop` 会得到 `400`；不传 `until` 则永远安全。⚠️ `shell` 会话的 `idle` 只在启动时触发**一次**，此后再也不会，所以在那里用「发送并等待」只能等到超时：没有 hook 的会话请用 `wait-output` 标记来同步。
+7. **只有 `claude` 与 `deepseek` 会话会发出 `stop`；`codex` 还会发出 `blocked`。** 它们来自 hook（Claude Code 自己的，以及 DeepSeek Harness 的状态桥接），codex 的 `blocked` 除外：批准、提问或信任对话框出现时，Codeman 从它的屏幕上读出这个信号（请在终端里回答）。`shell` 与其他外部 CLI（opencode/gemini/antigravity/pi/grok/omp）只接受 `idle`、`working` 与 `exit`，codex 另外接受 `blocked`。在这些模式上显式索要 `stop` 会得到 `400`；不传 `until` 则永远安全。⚠️ `shell` 会话的 `idle` 只在启动时触发**一次**，此后再也不会，所以在那里用「发送并等待」只能等到超时：没有 hook 的会话请用 `wait-output` 标记来同步。
 8. **没有任何东西会报告「就绪」，得自己显式等。** 新会话在 PID 出现之前一律回答 `{"signal":"exit","immediate":true}`（意思是*还没启动*，不是*崩了*），而全新 case 里的 `claude` 工作会话接着会停在 CLI 的信任对话框上。此时给它发提示，等待会在约 2 秒后因 `idle` 解除，看上去和一个跑完的回合一模一样，而文本其实卡在对话框里。下面的配方 2b 就是避开它的顺序。

+### `codeman agent`：每种 CLI 模式都能用的会话间命令
+
+上面的技能靠 Codeman 为每个会话写入的一段前导脚本，用 `curl` 和 `jq` 驱动 API。在它够不着的地方（`pi` 或 `shell` 会话、没有 `jq` 的机器），同样的环境依然存在（每个面板里都导出了 `CODEMAN_MUX=1`、`CODEMAN_SESSION_ID`、`CODEMAN_API_URL`），所以 `codeman agent` 把同一批动词打包成了命令。它只是 [API](#api) 一节所列端点之上的一层薄客户端：没有新路由，没有新的传输方式，认证和归属规则不变。在 case 的 `AGENTS.md` 里写一行就够了：*"other sessions: `codeman agent --help`"*。
+
+```bash
+codeman agent ls                                          # 列出会话；* 标记当前这个
+SID=$(codeman agent spawn scratch-1 --mode claude)        # quick-start，并在该模式有就绪标记时等到输入框出现
+codeman agent send "$SID" 'review src/, then say DONE' --until stop,exit --timeout 300000   # --wait = 默认信号集
+codeman agent read "$SID"                                 # 最后一条回答（按服务端对该模式的读取方式）
+codeman agent read "$SID" --tail 3000                     # 终端尾部，已去掉 ANSI（所有模式）
+codeman agent send "$SID" 'run the tests, then print WORKDONE followed by _4711'   # 没有 hook 的模式（opencode、pi 等）：让它分两半输出标记……
+codeman agent wait "$SID" --match WORKDONE_4711           # ……然后等拼接后的形式，提示本身的回显里永远不会出现它
+codeman agent interrupt "$SID"                            # 只发一个 ESC，对话保持完整
+codeman agent rm "$SID"                                   # 除当前会话外的任何会话
+```
+
+这些规则由命令强制执行，而不只是写在文档里：在 Codeman 会话之外它们拒绝运行，也绝不猜测 URL；`send` 只发送可打印文本加 Enter（像 `Ctrl+C` 这样的控制字节在 opencode 里就是 `app_exit`，所以 ESC 只以 `interrupt` 的形式存在，而且它从不追加 Enter）；`rm` 拒绝空 id、无法证明不是自己的 id，以及任一方向的前缀匹配。id 可以用 `ls` 打印的 8 字符前缀（通过列表解析；有歧义的前缀会被拒绝，短于 8 个字符的 id 在所有动词上都会被拒绝）。以 `-` 开头的提示要放在 `--` 之后（`send "$SID" -- "- fix the bug"`）。
+
+你发出的提示的回显也算输出：如果 `--match` 标记原样出现在提示里，它会立刻匹配，工作会话还什么都没做，所以提示要让它分两半输出。主机正在休眠的远程会话，对不等待结果的 `send` 会回答 `buffered`（Codeman 唤醒主机，等面板恢复后再敲入提示）或 `dropped`（超出唤醒缓冲区的上限，什么都不会敲入：退出码 `1`）。退出码：`0` 已送达/已匹配/收到信号，`1` 错误，`2` 超时，`3` 工作会话已退出或等待在没有回答的情况下结束（`delivered:false`、`ended:true`），`4` 被拒绝。`spawn` 在 stdout 上只打印 id（说明文字走 stderr），所以 `SID=$(…)` 恰好拿到 id。`--json` 让每个动词打印响应信封里的 `data`。在没有 hook 信号的模式上使用 `--until stop`，会原样透传服务端的 400：那里的答案是标记路径（`--match`），和技能完全一样。
+
+### MCP 服务器（`codeman mcp`）：从任意 MCP 客户端驱动 Codeman
+
+`codeman mcp` 是一个走 stdio 的 [Model Context Protocol](https://modelcontextprotocol.io) 服务器，因此任何 MCP 客户端（Claude Code、Claude Desktop、Codex、Gemini CLI、Cursor 等）都能在任意已安装的智能体 CLI 里启动 Codeman 会话、给它们发提示、等它们完成、读取回答并清理，无论是在 Codeman 内部还是外部。和 `codeman agent` 一样，它是 HTTP API 的客户端：没有新路由，认证和归属规则不变。
+
+```bash
+# Claude Code
+claude mcp add codeman -e CODEMAN_API_URL=https://127.0.0.1:3000 -- codeman mcp
+```
+
+```json
+{
+  "mcpServers": {
+    "codeman": {
+      "command": "codeman",
+      "args": ["mcp"],
+      "env": { "CODEMAN_API_URL": "https://127.0.0.1:3000" }
+    }
+  }
+}
+```
+
+```toml
+# Codex（~/.codex/config.toml）：为长时间等待调高默认 60 秒的工具超时
+[mcp_servers.codeman]
+command = "codeman"
+args = ["mcp"]
+env = { CODEMAN_API_URL = "https://127.0.0.1:3000" }
+env_vars = ["CODEMAN_MUX", "CODEMAN_SESSION_ID"]  # Codex 只给 MCP 服务器一个最小环境；这两个变量让它知道自己运行在哪个 Codeman 会话里
+tool_timeout_sec = 120
+```
+
+JSON 形式适用于 Claude Desktop、Cursor 和 Gemini CLI。服务器设置了密码时，在 `env` 里加上 `"CODEMAN_PASSWORD"`（或者让它读取数据目录里的 `.env`）。如果 PATH 上没有 `codeman` 命令（没走安装器的 git 检出），改用 `node /path/to/Codeman/dist/index.js mcp`。
+
+| 工具 | 作用 |
+| ---- | ---- |
+| `list_sessions` | 你能看到的每个会话，附带运行模式、状态、文件夹，以及这些工具是否可以给它发提示 |
+| `start_session` | 在一个 case 里（全新的临时文件夹或已有的 case）用任意已安装的 CLI 起一个新工作会话；等到它能接收提示为止 |
+| `send_prompt` | 输入一行提示并按 Enter；可选择等到这一回合结束 |
+| `wait_for_session` | 等待一个信号（`stop`、`blocked`、`idle`、`working`、`exit`）或输出里的一个字面标记 |
+| `read_output` | 最后一条回答、整段对话，或终端的最后若干字节 |
+| `interrupt_session` | 一次 Escape：停止当前回合，保留对话 |
+| `delete_session` | 关闭一个工作会话（它的 case 文件夹会保留） |
+
+这些规则由服务器强制执行，而不只是写在文档里：
+
+- **它绝不猜测服务器。** URL 来自 `CODEMAN_API_URL` 或 `--url`；没有配置时它照样启动并列出工具，每次调用都会说明该如何配置。
+- **只动自己的会话。** 发提示、中断和删除只限于这个服务器自己启动的会话（以及它运行在某个 Codeman 会话里时，该会话自己的工作会话）。列出、读取和等待对所有会话都可用。`codeman mcp --allow-any-session` 会解除这个限制，适合想让助手驱动自己现有标签的用户。它永远不会对自己所在的会话下手。
+- **等待时长适配客户端。** 一次等待默认 45 秒（Codex 默认在 60 秒时切断 MCP 工具），上限 600 秒；返回 `timed_out` / `still_working` 时再调用一次即可。
+- **两个协议时代都支持。** 它既能应答 2026-07-28 版本（每个请求带 `_meta`、`server/discover`），也能应答 2024-11-05 到 2025-11-25 的 `initialize` 握手。
+
 ### Hook（事件*回流*到 Codeman）
 
 Codeman 会注册 Claude Code hook，它们 `POST /api/hook-event`（`permission_prompt`、`idle_prompt`、`stop`、`task_completed` 等），让仪表盘实时响应。该端点在环回上免认证，但在受管隧道下需要 `X-Codeman-Hook-Secret` 头（从 `$CODEMAN_HOOK_SECRET_FILE` 读取）。通常你不需要手动调用它 —— Codeman 会自动接好 —— 但自主层正是靠它「看见」智能体在做什么。

+## Git worktrees of a case
+
+A local case whose folder is the top of a git repository can keep **worktrees** at `<case>/.claude/worktrees/<name>`, each on its own branch, so several agents on one repository never share a checkout. This is the layout Claude Code's own `claude --worktree <name>` uses (branch `worktree-<name>`), so either tool finds the other's worktrees. Remote (SSH) and Docker cases are refused with `400 INVALID_INPUT` before git runs, and so is a local case whose folder is at or inside a Docker case workspace: `git worktree add` runs the repository's post-checkout hook and checkout filters on this machine, and a container can write there. A case folder that is not a repository, is a bare repository, or sits below the repository's top level is `400` too. The case resolves the way quick-start resolves it (a linked case is admin-only in multi-user mode, everything else is the caller's own case space; another user's case is `404`), and a case folder on a mount that does not answer is `422 OPERATION_FAILED`, never `404`.

+- `excludeAdded` lists the lines appended to the repository's local `info/exclude` (in the real common git dir, never a tracked `.gitignore`) when git did not already ignore them: `/.claude/worktrees/`, so the main checkout does not show the worktrees as untracked, `/.claude/settings.local.json`, the hooks file Codeman writes for every claude session, which would otherwise make `git worktree remove` refuse, and the agent skill copy (`/.claude/skills/codeman/`, `/.agents/skills/codeman/`: every skills folder the CLI registry names) that sessions get while `agentSkillEnabled` is on, for the same reason.

A live session at or inside the worktree is `409` as well. With `deleteBranch=true` the branch is deleted with `git branch -d`, never `-D`, so an unmerged branch is kept: the response is still `200`, with `branchDeleted: false` and git's reason in `branchError`. Response: `{ removed: { name, path, branch, branchDeleted, branchError? } }`. A folder git does not list as a worktree of this repository, or a symlink in its place, is `404`/`400`. A worktree that is, sits inside, or holds a Docker case workspace is `400` too (git would run inside a folder the container writes, and the removal would delete that workspace under it). A managed worktree whose folder is gone (deleted by hand; the list reports it `prunable`) is still removable: git then only drops its record, which is what frees the name for a new worktree. A session never starts in one.

+**Starting a session in a worktree** goes through the normal create paths: `POST /api/quick-start` takes `worktree: "<name>"` next to `caseName` and runs the session (and the hooks, the agent skill and `modelOverride`) in the worktree folder; the response adds `worktree` and `workingDir`. It is refused for remote and Docker cases (`400`), for a worktree that is not a registered, managed one (`404`), and for a case that does not exist (`404`: a worktree launch never scaffolds a case). `POST /api/sessions` takes the worktree path as `workingDir` like any other folder.

+Claude Code reports the main conversation's prompt-cache state on its statusline (v2.1.251+); the exporter keeps it per session as `promptCache` on `GET /api/sessions` (`{ warm, ttl, expiresAt, recacheTokensIfCold, misses, lastMissCauses }`, epoch ms). The keep-warm sends one keep-alive turn shortly before an idle session's cache would expire; `keepWarmEnabled` (absent = the app-wide `promptCacheKeepWarm` setting applies, which a session spawned by another session does not inherit), the live `keepWarm` status and `lastRealPromptAt` (epoch ms of the last submit that was not a keep-alive, the cap's clock) ride the same session state. A keep-alive is a submit, so it moves `lastSubmitAt` like any prompt. A claude launch with keep-warm on also carries `"idleCompaction": false` in its `--settings` JSON (Claude Code 2.1.290 or newer).

+
+`status` is `{ enabled, idleCompactionOff, state, nextCheckAt?, reason?, nudges, lastNudgeAt?, budgetEndsAt? }` (`idleCompactionOff`: whether the session's current launch carries that opt-out; `budgetEndsAt` only while `enabled`) with `state` one of `off`, `armed` (waiting for the due time), `waiting` (due, deferred by a guard named in `reason`), `nudged` (sent, waiting for the next cache report) or `stopped` (`reason` says why). Two SSE events carry changes: `session:promptCache` (`{ sessionId, ...promptCache }`) and `session:keepWarm` (`{ sessionId, ...status }`), both change-only. The keep-alive turn's `hook:stop` and `hook:idle_prompt` broadcasts carry `acknowledgedReason: "cache keep-alive"`, no push is sent for them and the run summary does not record them; an idle approval already pending stays as it was (only a person spends its alert). Its `session:working` and `session:idle` broadcasts carry `keepAlive: true`.

+## Config backups
+
+Timestamped snapshots of the files that hold what a user has customized (`src/config-backup.ts`). On by default; a snapshot is taken at startup and whenever the tracked files' content changes (checked every 5 minutes), so there is one entry per real change. All four routes are admin only in multi-user mode (`403`), because the files include credentials. Responses carry file names and sizes; only the diff returns values, and never a credential's.
+
+Tracked files (a fixed list, relative to the data dir): `settings.json`, `clis.json`, `custom-model-hosts.json`, `webhook.json`, `intents.json`, `linked-cases.json`, `remote-hosts.json`, `remote-cases.json`, `docker-hosts.json`, `docker-cases.json`, `webviews.json`, `push-keys.json`, `users.json`, `.env`. Session state (`state.json`, which also holds cron jobs and respawn presets), logs, the hook secret and caches are not.
+
+Settings (synced, in `settings.json`): `configBackupEnabled` (absent = on), `configBackupDir` (absolute path, `~` expanded; empty = `<data dir>/backups/config`), `configBackupKeepCount` (2–500, default 20), `configBackupKeepDays` (0–3650, default 30; `0` = no age limit). A key absent from `settings.json` means the retention the newest backup in the folder recorded, and the default only when none did. Retention only ever deletes snapshot folders Codeman made there, and never the newest one. Each snapshot is a `0700` folder named `cfg-YYYYMMDD-HHMMSS` (server local time; `-2`, `-3`… on a same-second collision) holding the tracked files under their own names plus a `manifest.json` (`id`, `createdAt`, `reason` of `startup`/`auto`/`manual`/`pre-restore`, `appVersion`, the change-check `hash`, an `origin` id, the `keepCount` and `keepDays` in force, and a SHA-256 and size per file), all `0600`. A snapshot is never dated earlier than the instance's newest one, so a clock that read ahead once does not make every later pass write a copy. All four routes answer `503 OPERATION_FAILED` when a custom folder does not respond, and diff and restore answer `409` for a symlinked or group/world-accessible backup as well as a checksum mismatch. Only folders with that name and a valid manifest are listed, restored or pruned. Full guide: `docs/wiki/Config-Backups.md`.

 ## Webhook notifications
 
 Posts the Web Push events to ntfy, Slack, Discord or a generic JSON URL (Settings → Notifications). Off by default. The webhook URL is a bearer secret (anyone holding a Slack/Discord URL can post as it), so it lives in `~/.codeman/webhook.json` (0600), is **never returned**, and is kept out of `settings.json`. All three routes answer `403` for a non-admin in multi-user mode.

 **Instance isolation / multi-instance attach danger** — data dir (`~/.codeman`) and tmux socket (`tmux -L codeman`) are PROCESS-WIDE and shared by every Codeman on the machine, derived from `CODEMAN_INSTANCE` via `src/config/instance.ts` (`getDataDir()`/`dataPath()`/`DEFAULT_TMUX_SOCKET`). ⚠️ A 2nd instance on the SAME socket **discovers and attaches PTYs to the first instance's live sessions** (`tmux -L codeman attach-session …`), resizing/mutating them — `$HOME` isolation is NOT enough (tmux is system-global). To run two instances, give each a distinct `CODEMAN_INSTANCE` (scopes BOTH dir+socket: `~/.codeman-<name>` + `-L codeman-<name>`), or set `CODEMAN_TMUX_SOCKET` + `CODEMAN_DATA_DIR` individually. **`CODEMAN_INSTANCE` defaults to empty = the production layout (`~/.codeman`, `-L codeman`, port 3000)**, so this branch is safe to ship to master without disturbing existing installs. To run THIS beta alongside prod, launch with `scripts/run-beta.sh` (`CODEMAN_INSTANCE=beta` + `CODEMAN_PORT=5000`) — it never collides with prod's data dir/socket/port. Any new `~/.codeman/...` path MUST go through `dataPath()`, never `join(homedir(), '.codeman', …)`, and any new `tmux -L` caller through `resolveTmuxSocketName()` (same module): it applies the `CODEMAN_TMUX_SOCKET` override only when the name is safe and falls back to `DEFAULT_TMUX_SOCKET` otherwise. `TmuxManager` was the only such caller until `codeman tui` shelled out to tmux from a SECOND process for its degraded-mode listing and its attach handoff; a hardcoded `codeman` there would have pointed a beta instance straight at prod's panes.
 
+### The prefix table on Codeman's socket holds only send-prefix
+
+**Browser tabs are tmux clients, so tmux's prefix table must not reach `switch-client`** (`src/tmux-prefix-table.ts`, called from `createSession` before `respawn-pane`, and from `reconcileSessions()` at boot whenever the socket lists a pane, so sessions that survived an upgrade are covered). Every keystroke typed into a browser terminal reaches the `tmux attach-session` client behind it, and app.js deliberately lets Ctrl+B through to the terminal (readline, Claude Code's "ctrl+b ctrl+b"). With tmux's stock prefix table, Ctrl+B then `(` `)` `L` `s` `w` moved that client onto ANOTHER session, which the tab then showed and typed into under the original's label; `d` detached it, `$` renamed the session, `:` opened tmux's prompt. So the table is reduced to `<prefix> send-prefix` (the socket's configured prefix, read with `show-options -gv prefix`), once per tmux server in practice: the reset only runs while `list-keys -T prefix` shows anything else. ⚠️ Keep `send-prefix`: Claude Code inside tmux backgrounds a command with "ctrl+b ctrl+b". ⚠️ Never touch the `root` table, and tolerate (and re-bind after a reset) `C-<letter> detach-client`: `codeman tui`'s attach claims F1 and Alt+1..9 in `root` and the held-Ctrl alias `C-d` in `prefix` (`beginAttachHandoff`), and a session created mid-attach must not take that way out away. ⚠️ Key tables are server-wide, so what the TUI binds for its attach applies to browser tabs as well: F1 and `C-d` detach a tab's client, and **`M-1`..`M-9` (`switch-client -t <session>`) move it onto another session**, the very thing this reset exists to stop. The browser keeps a typed Alt+digit out of the terminal (`terminal-ui.js` swallows it for its own tab switching), but Esc followed by a digit within tmux's `escape-time` (500 ms on tmux 3.4) arrives as the same `M-<digit>`. This lasts for the length of the attach, and indefinitely after a TUI that is killed before `restore()` runs. Not fixed here; scoping those bindings to the TUI's own client is the open follow-up. ⚠️ The consequence for every terminal attach: `Ctrl+B d` does not exist on this socket. Anything that attaches a user's terminal claims its own way out for the attach, as `beginAttachHandoff` and `scripts/tmux-manager.sh` (F1 in `root`) do, and never advertises tmux's stock chord. Tests: `test/tmux-prefix-table.test.ts` (real tmux on a private socket, driven through a pty attach client), the wiring in `test/tmux-manager.test.ts`, the script in `test/tmux-manager-script-attach.test.ts`.

 **Signal availability is decided by MODE, not by `isExternalCliMode()`.** `stop` and `blocked` come from Claude Code hooks, so `hooksAvailableForMode()` is true only for `claude`: `shell` is not an external-CLI mode but installs no hooks either, so `until=stop` on a shell session is a guaranteed unresolvable wait dressed up as a timeout. The behavior split is deliberate and must survive refactors: an EXPLICIT request for an unavailable signal is a 400 naming the mode, while the DEFAULT set (`stop,idle,exit`) silently drops them and echoes the narrowed set back as `wait.until`, because omitting the parameter must never 400. Signal quality is not uniform either: `stop` is definitive (Claude Code says the turn is over), `idle` is inferred from output stabilization plus prompt detection and can flap mid-turn when a spinner pauses, which is why `stop` is the documented default to orchestrate on and `idle` is the fallback for sessions that emit no hooks. ⚠️ **`idle` being ACCEPTED for a mode does not mean it ever FIRES there.** `startShell()` emits exactly one `idle` on a 500ms readiness timer and nothing afterwards, so a shell session sits at `status:'idle'` no matter what its pane is doing; since send-and-wait and `fresh=1` both require a TRANSITION, both can only time out on a shell worker (measured: a default `wait` on `sleep 4` burned its full 25s). The ❯-prompt and spinner detection that drives the real `working`/`idle` cycle is Claude's output format, so hook-less modes synchronize with `wait-output` markers or `exit`, and the docs must say so rather than listing `idle` as "available" and letting the reader infer it is usable. ⚠️ **Signals are edge-triggered with no history**, and that is a real orchestration limit: a signal that fires while no waiter is registered is gone, unobservable by any later wait variant (`until=stop` after the turn ended just times out, `fresh` or not — measured, R2-A). Documented client patterns must therefore register the waiter before the event can fire (send-and-wait) or gather on latched `wait-output` markers with `from=buffer`; the skill's fan-out flow was rewritten accordingly, and "fire-and-forget N prompts, then gather signal-waits sequentially" must never be documented again. The durable fix, a server-side latched last-signal-per-turn, is deferred with Part 3 of `docs/agent-control-plan.md`. ⚠️ Relatedly, the route corrects liveness that `SessionStatus` cannot express: `currentSignalFor()` answers `exit` whenever `pid === null` (exited, detached, or created-and-never-started) **or the mux pane is dead**, because `Session` parks a DEAD PTY at `_status = 'idle'` and trusting the status would answer the default wait `{signal:'idle', immediate:true}` for a crashed worker while `until=exit` blocked forever on an event that already happened. ⚠️ **`pid` alone cannot carry liveness for a tmux-backed session**: that pid is the local `tmux attach` CLIENT, so a worker exiting inside its pane leaves `pane_dead=1` with the client alive and `pid` never goes null — the `pid === null` branch is unreachable in the normal configuration (unit tests exercise it because `MockSession` sets `pid` by hand; only a live instance showed the gap). Liveness is therefore probed at the mux layer: `workerIsDead()` consults `mux.isPaneDead(muxName)` with a ~750 ms per-pane cache, ONLY on blocking waits (measured: 0 tmux execs across 100 non-wait input POSTs — the browser hot path pays nothing), plus a refcounted 3 s `watchForDeadWorker` interval so a worker dying while a wait is parked resolves it in ~3 s instead of burning the timeout. The probe fails SAFE by construction ("cannot tell" is never "dead": non-mux sessions, a missing or throwing `isPaneDead`, all return false). On send-and-wait, a "successful" `send-keys` into a dead pane additionally overrides `delivered` to `false` and rolls the dedup seq back (`undoOnFailure`), because the bytes went nowhere and a retry against a restarted worker must not be refused as a duplicate. The cost is that a just-created session reads as `exit`, which the wire docs must spell out as "not started yet"; the fix lives at the route rather than in `signalForStatus()` because the registry deliberately holds no `Session` reference. ⚠️ Two `claude`-mode cases still lose hooks for reasons outside the registry: a Docker case cannot reach a loopback-bound Codeman without `CODEMAN_DOCKER_BRIDGE_HOOKS=1`, and a remote-SSH case runs the agent on another host whose hooks may never reach this server. Bounds are env-overridable (`CODEMAN_WAIT_MAX_MS`, `CODEMAN_WAIT_DEFAULT_MS`, `CODEMAN_WAIT_MAX_PER_SESSION`, `CODEMAN_WAIT_MAX_PER_OWNER`, `CODEMAN_WAIT_MAX_TOTAL`, `CODEMAN_WAIT_BUFFER_SCAN_BYTES`) and each is clamped to a hard bound so a typo degrades to the default instead of disabling the protection; they are internal tuning knobs like the rest of `src/config/`, NOT part of the SemVer-covered env-var surface in `versioning-policy.md`. Tests: `tesLine truncated

That is also why `deepseek` is the one non-claude mode the skill drives like claude: `spawn_workers alpha beta:deepseek` is a mixed fleet in one call, and `sendwait`/`last_text` need no variant.

A screen-read `blocked` is a LEVEL the server keeps reading (`Session.screenBlocked`), so the wait route answers it immediately (`currentSignalForWait()`) when the caller asked for `blocked`, and only then: such a pane is also `idle`, and `until=idle` must keep answering `idle`. See [Screen-read blocked dialogs](#screen-read-blocked-dialogs-codex).
 
 **Packaging as the `skills/codeman` agent skill.** The primitives are packaged as the `skills/codeman` agent skill, installable three ways: via `codeman skill install [--case <name>]` / `skill uninstall`; as a Claude Code plugin from the repo's own marketplace (`/plugin marketplace add Ark0N/Codeman` + `/plugin install codeman@codeman`, see the root-files note in CLAUDE.md); or auto-injected into a case on session create behind `agentSkillEnabled` (SYNCED, default OFF). ⚠️ WHERE it lands is registry data, `capabilities.agentSkillDir` (absent with `agentSkillInjection: true` = `.claude/skills`): `.claude/skills/codeman` for claude, `.agents/skills/codeman` for every other CLI that takes it (pi does not: a project skill triggers its trust prompt). `agentSkillDir` is a CLOSED enum (`AGENT_SKILL_DIRS`, schema.ts) because `clis.json` can set it and it decides where the server writes. The per-session preamble is seeded for every local session whose CLI takes the skill, and `codeman skill uninstall --case` removes the copy from every distinct registry directory (`registryAgentSkillDirs()`, cli.ts). ⚠️ Plugin skills are namespaced, so a Claude Code holding BOTH the plugin and a user-level or per-case copy lists the skill twice, `codeman` and `codeman:codeman` (measured 2026-09-14: neither shadows the other, both work); the docs tell users to pick one route.

 ### Plan-usage chip (statusLine telemetry)
 
-**Plan-usage chip** (`showPlanUsageLimits`, per-device: desktop default **ON** since 1.9.3, handhelds OFF) renders compact Claude and Codex provider rows. Claude Code (v2.1.80+) pipes a JSON blob to a configured `statusLine.command` on each render; on Pro/Max it carries a `rate_limits` object (`five_hour`/`seven_day` windows only — no Opus weekly field — each `{used_percentage 0-100, resets_at epoch-SECONDS}`). ⚠️ **Injected as an EPHEMERAL `claude --settings` CLI flag at spawn (2026-09-07), never written to disk** — `resolveStatusLineCliCommand()`/`ensureStatusLineExporterScript()` in `hooks-config.ts` (`generateStatusLineCommand()`/`applyStatusLineConfig()` remain, but only as the legacy disk-write self-heal path: a workspace an older Codeman build touched gets its stale `.claude/settings.local.json` entry stripped the first time a session starts there again). The exporter WRAPS a user's own real statusline (`findEffectiveUserStatusLineCommand()`, walking Claude Code's own settings precedence) rather than replacing it, and POSTs the `rate_limits` blob to `POST /api/status-telemetry`. That route (auth-exempt like `/api/hook-event` — localhost-only, hook-secret-gated whenever auth is active, COD-91) parses via `usage-telemetry.ts` (pure, unit-tested), broadcasts SSE `session:statusTelemetry` (de-duped per session by `telemetrySignature` since the statusline fires on every assistant message), and returns a compact plain-text footer for the exporter to **print-through** (foreground POST in the no-wrap branch so its own stdout becomes the footer, printing NOTHING on failure, `curl -sfk` plus `|| true`, since a bare brand word on the statusline is what discussion #405 opened with; backgrounded — `>/dev/null 2>&1 </dev/null &`, closing stdin too — only in the wrap branch, where the user's own command owns the footer; `curl --max-time 5` bounds a hung, not just refused, Codeman). Main Codex subscription usage comes from the signed-in host CLI's read-only app-server `account/rateLimits/read` request at startup and every 5 minutes; `usage-telemetry.ts` selects only the main `codex` bucket (never model-specific buckets such as Spark), maps whatever 5-hour/7-day windows it supplies, and omits the provider row when unavailable. Credentials stay inside the CLI and no auth material is sent to the browser. `plan-usage-latest.ts` merges both process-wide sources and replays them in the SSE init snapshot (`getLightState`) so `#planUsageChip` renders immediately on page load/reconnect. `planUsageChipEnabled()` remains the single resolver behind the checkbox and chip visibility (DISPLAY only) — the SAME `showPlanUsageLimits` setting also doubles as the server-side telemetry COLLECTION switch, read FRESH from `settings.json` by `readPlanUsageTelemetryEnabled()` at every claude session create/respawn (`TmuxManager.createSession`/`respawnPane`), never cached, with no per-session field and no per-request wire field — applies uniformly across every claude-creation path (interactive Run, cron, Ralph Loop API, quick-start) and survives a Codeman restart by construction (nothing per-session to lose). ⚠️ An ABSENT key reads as ON, the same way an absent `workspaceHooksEnabled` does: the desktop chip already shows as on for an install that never touched the setting, and the exporter posts only to this Codeman over loopback. Resolving the default in the reader is what keeps `GET /api/settings` a plain read. It briefly reconciled the key on first read (persisting `true` when absent), but `readJsonConfig()` answers `{}` for ANY read failure, not only ENOENT, and every page load hits that route, so one unlucky read replaced the whole settings file with a one-key file; pinned by `test/routes/system-routes-settings-get-plan-usage-default.test.ts`. ⚠️ The client sends `showPlanUsageLimits` in a settings save ONLY when that save FLIPS the chip relative to what the device had (`planUsageCollectionFlip()` in settings-ui.js): the chip defaults OFF on handhelds, so sending it on every save let a phone saving its font size persist `false` and switch collection off for every desktop, whose chip then went stale with no error anywhere. An explicit toggle on any device still writes the switch. Injection covers LOCAL tmux-spawned claude sessions only: the non-tmux direct-PTY fallback (`Session.startInteractive` when tmux is unavailable) and the remote/docker pane builders do not carry the flag.

It is sent with Copilot's OWN sign-in token, resolved by `resolveCopilotToken()` the way the CLI does (`COPILOT_GITHUB_TOKEN`, `GH_TOKEN`, `GITHUB_TOKEN`, else the plain-text `authTokens` entry for a github.com sign-in in `<COPILOT_HOME or ~/.copilot>/config.json`); a sign-in kept in the OS keychain is not read, so it shows no row. ⚠️ The read is **on by default**, like the Codex poll: it rides the same `showPlanUsageLimits` collection switch (an absent key reads as ON, so it runs even for a phone-only user whose chip is hidden), and turning Plan Usage Limits off stops the request. ⚠️ `readCopilotPlanUsageIfEnabled()` (copilot-plan-usage.ts) holds the three gates in order: the setting, then a token, then `isCopilotAvailable()`, whose resolver ends in a login-shell probe that a host without a Copilot sign-in must never run on each tick; a null clears the row. ⚠️ The token is never logged, stored or broadcast, the request refuses redirects (`redirect: 'error'`, so a redirect cannot carry the token elsewhere), and the row is admin-only on the wire like Codex's (`deriveSseHint`, and the init snapshot's `planUsage`). `plan-usage-latest.ts` merges the three process-wide sources (a Claude statusline sample keeps the `codex` and `copilot` keys) and replays them in the SSE init snapshot (`getLightState`) so `#planUsageChip` renders immediately on page load/reconnect. `planUsageChipEnabled()` remains the single resolver behind the checkbox and chip visibility (DISPLAY only) — the SAME `showPlanUsageLimits` setting also doubles as the server-side telemetry COLLECTION switch, read FRESH from `settings.json` by `readPlanUsageTelemetryEnabled()` at every claude session create/respawn (`TmuxManager.createSession`/`respawnPane`), never cached, with no per-session field and no per-request wire field — applies uniformly across every claude-creation path (interactive Run, cron, Ralph Loop API, quick-staLine truncated
 
 Further detail: the handheld OFF default comes from the mobile block in `getDefaultSettings()`. `planUsageChipEnabled()` backs the two call sites that must never disagree (the App Settings checkbox and the chip's visibility). The absent-key-reads-as-ON rule mirrors `readWorkspaceHooksEnabled()`. The same statusline payload carries a `prompt_cache` object since Claude Code v2.1.251 (`warm`, `ttl`, `expires_at` in epoch seconds, `recache_tokens_if_cold`, `misses`, `expected_rebuilds`, `hit_ratio`, `last_miss_at`, `last_miss_cause`); `StatusTelemetrySchema` lists every documented scalar field null-tolerant and keeps `causes` as `unknown` (the object gains fields across CLI versions and several are documented as possibly null, so a stricter shape would 400 the whole post and blank the footer — the recurring `.optional()`/null trap), while `parsePromptCache()` (usage-telemetry.ts) normalizes only the subset Codeman stores, so a hostile localhost payload cannot bloat state. The footer shows it as `cache:until HH:MM` (server-local clock, never a countdown: the footer only re-renders on statusline triggers) while warm and `cache:cold` otherwise. Claude re-runs the statusline when `expires_at` passes, so the footer flips to cold on its own. ⚠️ A user's OWN statusline wins the footer (the exporter then posts in the background and prints theirs), so the state ALSO lives on `Session.promptCache` (`setPromptCache()`, in `toState()` for the Session Options → Respawn readout `#promptCacheStatus`, worded by the pure `CodemanPromptCache.format` in constants.js, which also shows the hit rate, the last miss's `causes`, and — after a compaction (`/compact` or Claude Code's own idle compaction) or a tool-result clearing, the first warm report whose `recache_tokens_if_cold` is null after one that carried it — a `Context compacted at HH:MM` note that is NEVER an alert) and the route broadcasts `session:promptCache` (the STORED object, so the compaction stamp rides along) only when the report CHANGES (the statusline fires per assistant message). ⚠️ `setPromptCache()` returns a NEW object when it stamps `compactedAt`, never mutating the parser's output, which is what keeps broadcasting the stored object meaningful; the stamp needs a KNOWN prior `recache_tokens_if_cold` (a first report already inside the null window, such as a mid-session restart's, gets none), is carried while the window holds and dropped at the next request, and never reads `expected_rebuilds`: Claude Code's tracker clears the window and counts the expected rebuild in that same next request, so no single report carries both (2.1.294-2.1.296), and `adoptClaudeSessionId()` drops the whole report on a conversation switch so a post-`/clear` pane never shows the old prefix's warm-until. The last report is restored on a Codeman restart (the constructor's `promptCache`, set directly so it is not re-stamped, like `displayModel`) so the readout is not blank until the pane's next render; the readout is time-aware, so a value whose `expiresAt` has passed reads as cold rather than as a stale warm (and `parsePromptCache` validates the converted-to-ms expiry against the Date range, so a huge `expires_at` cannot render `NaN:NaN`). ⚠️ A launch without the exporter never reports, so `TmuxManager._resolveStatusLine()` records why on the mux record at every create and respawn (`MuxSession.statusLine`, published as `SessionState.statusLineExporter`: `injected`, `collection-off`, `workspace-statusline`, `remote`) and the readout names the cause instead of "not reported yet" forever. It is a spawn-time fact: flipping Plan Usage on later changes nothing until the next launch. ⚠️ This object, not the plan tier, is the source of truth for the TTL: Claude Code requests the hour only for a subscription within plan usage, and drops to five minutes on an API key, a cloud provider or extra-usage credits.
 
+### Prompt-cache keep-warm
+
+**Prompt-cache keep-warm** (`src/prompt-cache-keepwarm.ts`; per-session opt-in `keepWarmEnabled` on the Respawn tab, app-wide default `promptCacheKeepWarm` and cap `promptCacheKeepWarmMaxHours` under App Settings → System → Automation, both SYNCED, default OFF and 2 h; step 2 of Discussion #554): shortly before an idle claude session's prompt cache would expire, Codeman sends ONE keep-alive turn (`KEEP_WARM_NUDGE`, under 100 characters so Claude Code never reads the burst as a paste) so the next real prompt still reads the conversation from cache. Measured on two sessions of ~110k tokens: the nudge read 109,831 tokens from cache and wrote 70, replied `ok` in three seconds with no tool use, and a real turn seven minutes past the original expiry stayed a hit while the un-nudged control re-wrote 89,882 tokens with `last_miss_cause: ttl_expired_1h`; the payoff on real usage is concentrated in gaps of one to four hours, which is why there is a cap after the last real prompt rather than an indefinite loop (2 h by default: the maintainer's simulation over 30 days of gaps came out slightly cheaper than 3 h). ⚠️ **Codeman owns the idle policy for a keep-warm session.** Claude Code 2.1.289+ can compact an idle 1h-cache session by itself at 90% of the TTL (a server-flagged experiment, `fireAtFraction` tunable down to 0.5), which on the default timing always lands a minute before the nudge and leaves only a summary to keep warm. So a launch with keep-warm on carries `"idleCompaction": false`, folded LAST into the ONE `--settings` JSON with ultracode, the advisor and the statusLine exporter (`buildSpawnCommandFromRegistry`; never a second `--settings` flag, Claude Code takes one), so a keep-warm-off launch is byte-identical to one from before keep-warm (`test/cli-registry-spawn-golden.test.ts`). The `--settings` flag outranks user, project and local settings, which is why the key is conditional: everywhere else it would take Claude Code's own behaviour away with no way back. `decideIdleCompactionOptOut()` (tmux-manager.ts, pure) decides it once per create and respawn: keep-warm on (`keepWarmOn()`: the session's choice, else the app default, read fresh by `readKeepWarmSettings()`), the exporter `injected` (without `prompt_cache` reports keep-warm cannot run, and the opt-out alone would only cost the user the idle compaction), and claude's `idleCompactionSetting` gate (`capabilities.gates`, 2.1.290, the first release whose settings schema has the key; 2.1.289 already idle-compacts with no opt-out), fail-closed through `launchGatePasses()` exactly like `--name`: an unknown version means no key, and a log line says so. The result is recorded on the mux record (`MuxSession.idleCompactionOff`, like `statusLine`, persisted in mux-sessions.json) and published in the keep-warm status as `idleCompactionOff`; a session switched on after launch is kept warm best-effort (a relaunch to install the opt-out would cost exactly the re-write being avoided) and its readout says Claude Code's idle compaction may still run until its next launch, which any relaunch (dead-pane recovery, a custom-model `restartCli()`) fixes for free since every relaunch re-decides. ⚠️ The deadline is the statusline's `prompt_cache.expires_at` (`Session.promptCache`), never idle detection or the plan tier, and a `5m` lifetime is a hard stop (a nudge every four minutes costs more than the miss it prevents; API-key users get the hour from `CLAUDE_CODE_PROMPT_CACHE_TTL=1h` in `envOverrides`). ⚠️ `decideKeepWarm()` is the ONE rulebook and every guard lives in it, tested as a table: the effective opt-in (`keepWarmOn()`; a session an agent spawned, `parentSessionId`, does not inherit the app default, since an idle worker that reported done looks exactly like one that will be prompted again and most never are; its own switch still works), the launch's `statusLineExporter` is `injected` (which also stops every CLI without cache telemetry; the toggle line says why in the readout's own `PROMPT_CACHE_NOT_COLLECTED` words), a warm cache with an expiry, no `compactedAt` this gap (a compaction already replaced the context, and the stamp is dropped at the next request, which re-opens the next gap), not a `5m` lifetime, at least `KEEP_WARM_MIN_TOKENS` at stake, a live pane (a pid AND no recorded `paneExit`: an agent that exited in a `remain-on-exit` pane keeps its pid), no usage-limit pause (auto-resume's, or, read off the same pane capture as the composer, a usage-limit message whose reset is still ahead, since auto-resume tracks pauses only while it is on), no automation (respawn running, a Ralph loop active, a task assigned, or an agent long-polling `wait`), inside the cap measured from `lastRealPromptAt` (else `createdAt`), due at `expires_at` minus `KEEP_WARM_LEAD_MS` but not within `KEEP_WARM_LAST_CHANCE_MS`, idle, no open permission or question dialog, an EMPTY composer (`composerIsEmpty()` in session-submit-verifier.ts reads the last glyph line AND its Line truncated

 ### Cron jobs
 
 **Cron (cron-style `CronJob`s)**: saved, named jobs with a recurring schedule (`once`/`interval`/`daily`/`weekly`), enable/disable, Run Now, next-run calc, and per-job run history (`CronJobRun`). ⚠️ **Distinct from the legacy `ScheduledRun`** (`/api/scheduled`, a run-now duration-bounded autonomous loop) — the two never interact; the legacy concept keeps the `Scheduled*` names, the recurring-job feature is `Cron*`. `CronService` (`src/cron/cron-service.ts`) owns CRUD + the 30s background due-tick (`tickDueJobs`, registered via `cleanup.setInterval` in `server.ts`; `init()` recomputes nextRunAt on boot) and **reuses the existing session layer** (create → `addSession` → `setupSessionListeners` → `startInteractive`/`startShell` → prompt via `writeViaMux`/`write`) rather than rebuilding tmux logic. Next-run math is pure/unit-tested in `cron-time.ts` (SERVER-LOCAL timezone for daily/weekly). Dup-launch guard = `lastDueKey` (jobId:fireTime); schedule is advanced BEFORE launch so a slow launch can't re-trigger. `once` jobs self-disable after firing (`completedOnce`). Persisted via `AppState.cronJobs`/`cronJobRuns` (StateStore accessors).

 ### Terminal scrollback: strip flavors and wheel/touch forwarding
 
-**Three strip flavors, one carry** (#205, `session.ts:_handleTerminalOutput`): the FULL strip (`isAltScreenStripMode` = codex/claude/gemini) removes alt-screen toggles, `3J`, and mouse-tracking DECSETs. The MOUSE strip (`isMuxMouseStripMode` = opencode) removes alt-screen toggles AND the mouse DECSETs but KEEPS `3J` — the middle case, for a mouse-capable full-screen TUI: its tracking DECSETs reach the browser (tmux `mouse off` passes the pane's modes through to the client), xterm obeys them, and then every DRAG is reported to the TUI instead of selecting text — so mark-and-copy silently did nothing (measured 62 `none` / 18 `any` over 16s, 5/5 dead drags while `any`) and the obvious fallback, Ctrl+C, is opencode's `app_exit`. `3J` stays because a TUI is not a `clear` consumer. Every other mode (shell/antigravity/pi/grok/deepseek/omp) 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 — which is exactly why the mouse strip is opt-in per CLI and not part of the narrow flavour). ⚠️ 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 three branches; the frontend gate (`_shouldReportMouseToCli()`) keeps no mode list at all: it reads only the published `cliMouseTracking`, which the server sets solely in a DECSET-stripping branch (full or mouse), so it can only be true for a mode whose DECSETs are stripped — the modes where the browser's hand-encoded tap (`_sendSyntheticSgrTap`) is the only way a click still reaches the CLI. Whichever modes the registry strips, the browser follows (pinned in `test/claude-scrollback-strip.test.ts`). The chunk-boundary carry (`_altScreenSeqCarry`) runs for all three flavors. Tests: `test/claude-scrollback-strip.test.ts`, `test/terminal-touch-tap.test.ts`.

The MOUSE strip (`isMuxMouseStripMode` = opencode and copilot) removes alt-screen toggles AND the mouse DECSETs but KEEPS `3J` — the middle case, for a mouse-capable full-screen TUI: its tracking DECSETs reach the browser (tmux `mouse off` passes the pane's modes through to the client), xterm obeys them, and then every DRAG is reported to the TUI instead of selecting text — so mark-and-copy silently did nothing (measured 62 `none` / 18 `any` over 16s, 5/5 dead drags while `any`) and the obvious fallback, Ctrl+C, is opencode's `app_exit`. Copilot is the same shape (measured on 1.0.95: alt screen, mouse reporting on): left on the narrow strip, Auto Copy and copy-on-select did nothing and only Shift+drag selected. `3J` stays because a TUI is not a `clear` consumer. Every other mode (shell/antigravity/pi/grok/deepseek/omp) 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 — which is exactly why the mouse strip is opt-in per CLI and not part of the narrow flavour). ⚠️ 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 three branches; the frontend gate (`_shouldReportMouseToCli()`) keeps no mode list at all: it reads only the published `cliMouseTracking`, which the server sets solely in a DECSET-stripping branch (full or mouse), so it can only be true for a mode whose DECSETs are stripped — the modes where the browser's hand-encoded tap (`_sendSyntheticSgrTap`) is the only way a click still reaches the CLI. Whichever modes the registry strips, the browser follows (pinned in `test/claude-scrollback-strip.test.ts`). The chunk-boundary carry (`_altScreenSeqCarry`) runs for all three flavors. Tests: `test/claude-scrollback-strip.test.ts`, `test/terminal-touch-tap.test.ts`.
 
 ⚠️ **What a mouse-DECSET strip (full or mouse) 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 in fullscreen (so clicks keep being reported exactly as before; the default inline renderer holds none, measured on 2.1.283 even with `/model` open), 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.
 
-**Only claude ≥ 2.1.187 with mouse tracking on forwards the wheel; everything else 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. Claude repeats this exactly in its default INLINE renderer (measured on 2.1.280: `alternate_on=0`, `mouse_any_flag=0`, `history_size` grows), and swipes on iOS Safari were dead there while codex scrolled; only fullscreen claude (`CLAUDE_CODE_NO_FLICKER=1` or `"tui": "fullscreen"` in `~/.claude/settings.json`: alt screen plus modes 1003/1006) pages its transcript on wheel reports. So claude forwards only while the server-observed `cliMouseTracking` flag is true; a stale-false flag after a server restart falls through to the PageUp/PageDown fallback, never a dead wheel. ⚠️ "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 are gated by `_shouldReportMouseToCli()` (the server-observed `cliMouseTracking` flag, recorded by `_recordStrippedMouseMode` in session.ts as it strips, so only ever true for a stripped mode): 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 forwarding requires observed mouse tracking: Claude ≥ 2.1.187, tracked Codex or tracked Copilot** (`terminal-ui.js:_shouldForwardWheelToApp`). The original #227 measurement remains valid for **Codex 0.147.0 inline**: `alternate_on=0`, `mouse_any_flag=0`, growing tmux history, and SGR wheel reports do nothing. Claude 2.1.280 inline similarly reports `alternate_on=0`, `mouse_any_flag=0`; forwarding there swallows gestures, so it keeps local scrollback. Fullscreen Claude (`CLAUDE_CODE_NO_FLICKER=1` or `"tui": "fullscreen"`) enables mouse tracking and accepts reports. **Fresh Codex 0.163.0 fullscreen measurement (2026-10-18, isolated local tmux pane)**: `alternate_on=1`, `mouse_any_flag=1`; one `\x1b[<64;10;10M` report moves the transcript one row upward, and `\x1b[<65;10;10M` restores the original screen. This is capability evidence, not a minimum-version promise: untracked Codex (including a 0.162.0 measurement (2026-10) with `mouse_any_flag=0`) keeps local history or the hollow-pane paging fallback. Codex does not publish the Claude-only CLI version field, so its gate requires the observed flag rather than a Claude version. The registry records this as `wheelForward.mode: 'always'` (observed mouse tracking is still required); Claude remains `version-gated`. A stale/false flag after startup cannot authorize forwarding. ⚠️ A strip mode alone is not evidence that a CLI consumes SGR reports. Verify with a real `\x1b[<64;c;rM` write into a live pane before adding a mode here. Hand-encoded SGR taps remain independently gated by `_shouldReportMouseToCli()`; the older #325 no-op measurement describes untracked inline Codex and must not be generalized to newer tracked fullscreen renderers. Shift/local-history opt-outs and xterm's native mouse/alternate-screen handling remain intact.
 
-**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 while `cliMouseTracking` is true, i.e. fullscreen; 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`.
+**Copilot also receives forwarded reports** (1.0.95 measured in tmux: alt screen, `mouse_any_flag=1`): its mouse DECSETs are stripped so a drag selects, which also stops xterm encoding the wheel for it, so `_shouldForwardWheelToApp` sends the same SGR reports by hand while `cliMouseTracking` is true; six `\x1b[<64;…M` reports moved its transcript 18 lines, a phone swipe takes the same gate, and there is NO version gate.
 
-**A false gate on a hollow pane must not mean a DEAD gesture** (#205 round 2, `_maybePageCliTranscript`): every way `_shouldForwardWheelToApp()` returns false leaves a repaint-mode pane scrolling a buffer that has nothing in it (`baseY === 0`) — the version probe came back empty, the CLI really is older than 2.1.187, the `cliMouseTracking` flag is unset (inline claude, or fullscreen right after a server restart), or the user turned on `terminalWheelLocalScrollback`. **opencode is the fifth case, and the gate is false there by design**: its TUI runs on the ALTERNATE SCREEN (1.18.31 measured: tmux `alternate_on=1`, `history_size=0`), so the buffer is hollow, and it IGNORES SGR wheel reports entirely (six `\x1b[<64;…M` reports against an idle pane left the capture byte-identical) while still paging its transcript on PageUp/PageDown (`messages_page_up/down`) — so paging is the only gesture that can reach it, and without it the wheel was silently dead in every opencode tab. The 1.12.0 retest reported exactly that shape for Claude: a wheel that did nothing at all while Fn+Up (PageUp) paged back through intact text, which is the proof that the CLI's own history and the PTY input path were both fine. So under the guard (`_localScrollbackIsHollow()`: the `transcriptPageKeys` capability, gate false, `baseY === 0`) wheel and touch travel is translated into coalesced `\x1b[5~` / `\x1b[6~` through the same 40ms queue as the SGR reports, at half a screen of travel per page key (the key jumps a whole screen; a 1:1 mapping was unusably slow with a discrete wheel). ⚠️ The first event of a trackpad-sized gesture (opening under 2 rows) pages AT ONCE and the travel it skipped is owed back by the rest of the gesture (one page per half screen still). Waiting for half a screen first meant an ordinary trackpad flick (well under 19 rows on a 38-row pane) sent nothing at all. A larger opening event is a mouse-wheel notch (100 px is 4 rows) and accumulates as before, or slow notches, each its own gesture past the gap, would page a full screen apiece. ⚠️ What starts a NEW gesture (and so may pre-pay) is narrow, because every boundary is another free page: (1) a TOUCH CONTACT is one gesture, never split by time: the touch paths tag every call, touchmove and momentum frames alike, with `touchId` (one per touchstart), and a different id (or a wheel event after a touch) is a boundary. touchmove only calls once per whole cell of finger travel, so a slow drag arrives as single lines further apart than any gap; on the gap alone 12 lines at 170 ms each sent 12 PageUps (measured through the real listeners, `test/terminal-touch-paging.browser.test.ts`). (2) Outside a contact, 150 ms of quiet (`PAGE_KEY_GESTURE_GAP_MS`), stretched to one second (`PAGE_KEY_DEBT_MS`) while a pre-paid page is still owed in the SAME direction, so slow small wheel ticks (40 px every 250 ms, a Firefox 1-line notch) pay the debt back instead of each pre-paying a page; after a second of quiet the debt lapses and the next small tick pages at once again. The debt also ends the moment travel repays it (reaches or crosses zero): the rest is plain travel and the 150 ms gap applies again. (3) A direction change inside a gesture (within the gap, or within one contact) drops a pre-paid debt (it belongs to the other direction) and accumulates WITHOUT pre-paying, so a +/-3 px trackpad wobble pages once for its opening event and then nothing; a reversal after the gap is a new gesture and pages at once. A tab switch also starts a new gesture. ⚠️ These gesture rules (first-event page, contact and debt lifetimes, reversal handling, notch accumulation, pinch and sideways-swipe consume) are ONE pure helper, `CodemanTerminalInput.pageKeysForGesture(state, ev, lines, rows, now)`, which both panes call with their own state; never re-derive them in a pane. ⚠️ Three gestures are consumed WITHOUT paging: a pinch (`ctrlKey`, Chrome's trackpad-pinch wheel events), a mostly horizontal swipe (both deltas present and `|deltaX| > |deltaY|`; the touch path locks its own axis first), and anything while the pane's OWN session has the alert `'action'` (a pending `permission_prompt` or `elicitation_dialog`, `updateTabAlertFromHooks` in app.js), so a page key never lands in an open dialog's selector; the primary pane logs that case as `page-keys-dialog-open` so a wheel dead under a stale alert leaves a `[scroll]` line. The dialog check is the one rule outside the helper, because it is per pane: the primary pane reads `tabAlerts` for `activeSessionId`, a tile for its own `sessionId` (usually not the active one). ⚠️ Which modes page is the registry's `capabilities.transcriptPageKeys`, published as `window.__codemanTranscriptPageKeys`, never an id check in terminal-ui.js. Today that is claude, codex and opencode. Codex is on it although it is never forwarded the wheel: newer codex draws on tmux's alternate screen, which the full strip hides from xterm, so its pane is hollow too, Line truncated
+Codex 0.163.0 approval check in that isolated read-only/on-request session: the "Would you like to run the following command?" prompt remained on `1. Yes, proceed` after SGR wheel-up and wheel-down over both the transcript and approval option rows 36/37; the requested marker file was not created. The background transcript can scroll while the approval prompt remains fixed. Codeman does alert on this prompt: `src/web/screen-blocked.ts` reads Codex dialogs off the pane (`capabilities.workDetect.blockedLine`) and broadcasts `hook:permission_prompt`, which `_onHookPermissionPrompt` (settings-ui.js) records and `updateTabAlertFromHooks` (app.js) turns into the `'action'` tab alert, and both page-key fallbacks check it. The SGR wheel path deliberately does not consult that alert, because this measurement showed wheel reports leave the approval selection unchanged. Native Codex owns its approval selection; do not mistake a hook-only unit fixture for approval-dialog evidence.
+
+Native wheel travel retains upstream pixel/line/page units (100 px = 4 lines; Firefox 3-line events = 3 lines); no one-tick-per-event policy is introduced here. A fresh native gesture at or above 0.1 row (2.5px) rounds its opening travel to at least one tick (subject to the per-event cap), so an isolated 4px mouse click responds, 40px sends two ticks and 120px sends five. The signed remainder is carried forward; travel discarded by the per-event cap does not become a backlog. The signed remainder is debt repaid by subsequent same-direction events: ten 2.5px events still total one tick. Debt/fractions expire after a 150ms gap; a reversal inside that gap discards the old debt without another pre-payment. Sub-threshold jitter does not pre-pay. The first native report of each tab visit bypasses the 40 ms batching timer; later reports coalesce and only unsent bytes can be cancelled on reversal. Every queued batch belongs to its originating session, so switching tabs cannot send its bytes into the newly selected pane. Zero-delta events leave pending movement untouched. Tiles use the same helpers and their own queue/session.
+
+**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 or tracked Codex, with observed `cliMouseTracking`; see the native measurement above), the plain wheel AND touch drags forward as coalesced SGR reports (`_forwardScrollToApp` → `_sendSyntheticSgrWheel`, 40ms batches after the first native report, 5-tick per-event cap; no aggregate byte/tick limit). 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). Touch asks `_shouldForwardTouchToApp()`, which is that gate plus one branch: in any session mode, a drag and its fling momentum also forward as SGR wheel reports while xterm itself tracks the mouse (`modes.mouseTrackingMode` other than `none`/`x10`) with SGR encoding (`_core.coreMouseService.activeEncoding === 'SGR'`, an xterm private pinned by `test/xterm-private-api.test.ts`; DEFAULT, X10 and SGR-pixel apps fail closed). xterm encodes a native wheel for such an app itself, but the touch listeners consume the drag, and a local scroll shows nothing useful: a direct-PTY app is on xterm's alternate screen, and in a tmux-backed session xterm stays in the normal buffer holding stale tmux repaints. `_wheelScrollLinesFloat()` 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).

 ### The watching signal (a quiet pane that is not waiting for you)
 
 **A session that armed a monitor, backgrounded a shell or started a background terminal ends its turn and goes quiet, and a minute later Claude Code's idle notification arrives.** Before this existed, that prompt became an approval item like any other, so every surface filed the session under NEEDS YOU with nothing for a human to answer. The CLI says which kind of quiet it is on its own screen, and reading that row is the whole mechanism: `capabilities.workDetect.watchingLine` (optional, per CLI) plus `watchingLines` (how many non-blank rows at the foot of the screen may hold it, default `WATCHING_TAIL_LINES` = 1). `_confirmIdle()` already captures the pane at the moment a turn ends, so `_readWatching()` runs `watchingLabel()` (pure, `session-activity.ts`) over that same capture; the label lands on `Session.watching` and rides `toLightDetailedState()` out to every payload. ⚠️ It is cached BESIDE `_lastPaneProbeWorking` and goes stale with it, because the probe returns its cached boolean without re-capturing inside `PANE_PROBE_MIN_INTERVAL_MS` and a label from a capture nobody took is a guess. ⚠️ A capture that FAILS clears the label (and announces the change) rather than keeping the last one: a stale label opens the next idle prompt already acknowledged, so keeping it would turn a failed `capture-pane` into a missed alert, while clearing it costs at most an alert the next readable capture takes back. ⚠️ It then FREEZES once `_confirmIdle()` concludes — nothing looks at the pane again until it produces output — which is correct rather than tolerable, since work ending repaints the pane either way (a monitor firing wakes the agent; codex drops its background-terminal row by itself); a timer to keep it fresh would spend a `capture-pane` per idle session per tick to learn nothing. ⚠️ A server restart looks like a hole in that and is not one: the field is live state and starts empty, but reconciliation re-attaches the pane and the attach repaint arms the idle confirmation, which probes and re-reads the label with no input from anyone (measured 2026-09-23, back within ~20 s). A restored session showing no label has no chip on its screen.

 ⚠️ **A chip that waits on a HUMAN must never count as watching**: Claude's Artifact comment monitor (an agent that published a page and hears nothing until somebody comments) is refused for the whole row by a `^`-anchored negative lookahead keyed on "Artifact" alone, so a footer cut off mid-chip is refused too, and the `^` is what stops the engine retrying past the chip and reporting a shell beside it.
 
-**⚠️ The label is pane-derived, so the window and the anchor are a trust boundary, not formatting.** An agent that gets its own text matched silences its own alert. Two things prevent it, and BOTH belong to whoever adds a pattern for a new CLI: the window must cover only rows that CLI draws, and the pattern must anchor on chrome only that CLI can produce. Claude satisfies both — its chip is the LAST row, so the default window of one row excludes even the status line directly above it, whose content comes from a `statusLine` command a bypassed session can write into its own `.claude/settings.json`. Codex does not: its row sits above the composer, and the slot it occupies holds the last row of the TRANSCRIPT whenever no terminal is running, so matching the complete row raises the bar without closing it. What contains that is `hooks: 'none'` — no hook event from a codex session reaches `notePrompt()`, so a forged label costs a wrong badge and nothing else, and a CLI that gains hook signals must not keep a pattern that soft. The label is also ANSI-stripped and capped (`MAX_WATCHING_LABEL_CHARS`) at the source, and every interpolation of it into markup goes through `escapeHtml()`, since a config-supplied capture group decides what it holds. Tests: `test/session-watching.test.ts` (the label and both CLI patterns), `test/watching-no-alert.test.ts` (the negative claim across all four surfaces).

+### Screen-read blocked dialogs (codex)
+
+**Codex is the one CLI Codeman launches with its approvals ON by default, and it has no hook to say it stopped for one** (`hooks: 'none'`), so a codex session parked on "Would you like to run the following command?" read as plainly idle, and one parked on a question as WORKING. `capabilities.workDetect.blockedLine` (optional, per CLI, plus `blockedLines`, 1 to 24, default 1) names the dialog's chrome; `_probePaneWorking()` reads it off the same capture the idle confirmation takes (`_paneShowsBlocked()` → `isBlockedScreen()`, pure, `session-activity.ts`: the last `blockedLines` non-blank rows joined with `\n`, tested once, so a pattern can demand several markers and end on `$`), and `Session` emits `blockedChanged`. `session-listener-wiring.ts` hands that to `web/screen-blocked.ts`, which raises EXACTLY what a Claude `permission_prompt` hook raises (`sessionWaits.notifySignal('blocked')`, an Approvals Inbox item, the `hook:permission_prompt` broadcast with `source: 'screen'`, push and webhook, a run-summary row), so the tab alert, phone overview, TUI and every other consumer needed no second code path; clearing resolves the item it opened, and `approval:resolved` clears every client.
+
+⚠️ **ALERT ONLY, never a keystroke.** The text is pane-derived and the agent writes most of the pane, so the pattern must end on chrome only the CLI draws at the FOOT of the screen, where a dialog replaces the composer (codex's: a `› N.` option row, then its key-hint row as the last row, allowing for that row to wrap; a transcript that quotes every word still has codex's column-0 composer row below it). The item is `answerInTerminal` (#610's shape), the answer route refuses it, push carries no `approvalId`, and Codeman never answers such a dialog itself, so a forged match costs a false alert and nothing more. The message every surface shows is built from the CLI's registry label, never from the screen (a question's text and a command preview are the agent's to choose).
+
+⚠️ **Raise on one reading, clear on two, and keep reading while it is up.** The raise needs no timer: a dialog is drawn at the END of a burst of output, so the settle probe (pane quiet, then capture) sees it. The clear does: answering resumes the turn, a busy pane never reaches the settle path again until the turn ends, and the red alert outlived the dialog by minutes, so `_blockedRecheckTimer` re-reads the screen every `BLOCKED_RECHECK_MS` (2 s, one `capture-pane`, only while a dialog is up; cleared in `_clearAllTimers()`). ⚠️ That read is a synchronous exec (about 8 ms of blocked event loop, measured 2026-10-14) and a dialog can sit unanswered overnight, so the timer SKIPS it while the pane is quiet: a dialog leaves the screen only through a repaint, which reaches the session as PTY output, so nothing drawn since the last reading that saw the dialog (`_lastActivityAt < _blockedSeenAt`) means it is still up; a safety-net read still runs every `BLOCKED_QUIET_RECHECK_MS` (30 s). Never once a reading has MISSED the dialog (`_blockedGoneReads > 0`): tmux updates the pane before it sends this client the repaint, and the confirming read must not wait for output. It clears after `BLOCKED_CLEAR_READS` (2) readable captures in a row without the dialog, because one capture can land inside a full-frame repaint, and a clear followed by a re-raise sends the alert, push and webhook twice for one dialog. An unreadable capture (`null`) changes nothing in either direction. A new pane (`_resetBuffers()`) and a PTY exit clear it, announced, while the listeners are still attached. The working probe decides blocked-over-working from THIS capture, never from `_screenBlocked`, which lags a vanished dialog by design.
+
+⚠️ **Hooks win.** `raiseScreenBlocked()` does nothing for a session whose CLI passes `hooksAvailableForMode()`, so a CLI that declared both could never alert twice for one dialog; and the inbox item gets no `capture` callback (only the frame, as context), because the inbox's option parser and staleness sweep are shaped for Claude's dialogs and the SESSION owns this item's lifetime. ⚠️ Codex's `Implement this plan?` after a plan turn is deliberately not matched: its `enter select · esc back` footer is the same as `/model`, `/permissions` and `/review`, menus the user opened at the keyboard, and the plan turn has ended there.

 - **Edits are named operations, saved serially.** `createEditCoordinator` applies `createGroup` / `renameGroup` / `deleteGroup` / `reorderGroup` / `moveRef` to the rail at once, then sends ONE `PUT /api/tab-layout {baseVersion, layout}` at a time; edits made meanwhile wait and go out on the version that write returns. A 409 carries the server's layout: the in-flight operations are replayed onto it (an operation that no longer applies is dropped and reported) and re-sent, at most `maxAttempts` times; a 400 re-reads once (a second 400 is reported as a failed save, not as a race); anything else reports and re-reads. A `moveRef` moves the session together with the sessions that still follow it and marks a hand-moved child `placement: 'manual'`, mirroring the server's `moveRef`, and `normalizeLayout` keeps `placement` because whole layouts are written back. `_onTabLayoutChanged` / `_applyTabLayout` defer a read while a write is in flight and rebase unsaved edits onto a read otherwise. ⚠️ A FAILED read (`_applyTabLayout(null)`) while edits are pending keeps the held layout and the editor and re-reads after the write settles: disposing there would orphan the in-flight write, whose 409 then never gets its rebase. Any path that does drop unsaved work says so in a toast. On `pagehide`, unconfirmed operations go out in a `keepalive` PUT AND into sessionStorage as `{ owner, baseVersion, savedAt, operations }`; after reload they replay onto the fresh layout (a no-op when the keepalive landed), but only for the same owner, within `TAB_LAYOUT_PENDING_MAX_AGE_MS` (60 s), and never onto a layout older than the copy's base. A "Move to <group>" with no anchor carries no `index`, so a replay still puts the row last.
 - **Every way in has a keyboard path.** The session row menu (Shift+F10 in the tree, the rail's overflow button) gains Move up/down, Move to <group>, Move to Ungrouped and Move to new group in the vertical rail (only "new group" before the first group exists; nothing on the strip). A group header opens its menu with Shift+F10 / ContextMenu, right-click or its hover glyph (a non-focusable, `aria-hidden` span: a treeitem holds no interactive children), and F2 renames it inline (Enter commits and refocuses the header; a commit by BLUR leaves focus where it went, since refocusing from inside the blur handler overrides the user's click). The glyph stays visible under `@media (hover: none)`: a touch tablet has no hover and no long-press `contextmenu`. Group names in "Move to" labels are quoted, so a group named "New group" or "ungrouped" cannot read (or translate, case-insensitively) like the fixed entries. The menu closes on Escape (which it consumes before the global Escape handler), a pointer outside, Tab, focus leaving it, a resize, a second open and any full re-render. It borrows the `.tab-rail-action-menu` class for its look only: `closeTabRailActionMenu()` excludes `.tab-layout-group-action-menu`, so closing the row menu (every `session:deleted` does) cannot strand the group menu's listeners. The inline group editor shares `_activeRename` with the session rename, so only the CURRENT editor may release `_inlineRenameActive`.
 - **New, child and web tabs land in groups.** A group menu's "New session" (`createSessionInTabGroup`) runs ONE launch with `run({ count: 1, tabGroupId })`; every launch path puts `tabGroupId` on its create request (`POST /api/sessions` or `/api/quick-start`), and `TabLayoutService.sessionCreated(owner, id, { tabGroupId }, register)` places the session at the end of that group in the SAME versioned write that first records it. The session enters the live map inside the owner lock (`register`, rolled back if the write fails), so no queued layout edit can commit it first. The group is looked up in the creating owner's own layout, so an unknown, deleted or foreign id is ignored rather than failing the spawn, and an explicit group is a hand placement (a child placed this way is `manual`). The create response carries the committed `tabLayout`, adopted before the tab is drawn. A session spawned by another one (`parentSessionId`) and placed by nobody lands after its parent: the server's normalization puts it after the parent's rows in the parent's container, and `project({ parents })` draws a not-yet-stored child there at once. Whether it then FOLLOWS its parent is the synced `spawnedTabsFollowParent` setting (default OFF), which `sessionCreated()` reads fresh through the `childrenFollowParent` dep: off, the child is marked `manual` in that same creating write; on, it follows until moved by hand. Deciding at creation is enough, so flipping the setting leaves existing tabs alone. A hand move makes a following child `manual`; with the setting on, the row menu notes where a child sits (following, placed by hand, parent closed, parent loop; plain text, never a focusable menu item) and offers "Follow parent again" only to a `manual` child, which clears `placement` and is re-derived by the server on save. With the setting off the row menu says nothing about placement. A legacy `PUT /api/session-order` (strip or phone drag, a same-section Ctrl+Shift+{/}, a device without a layout, an admin's cross-owner order) marks a child `manual` ONLY when the requested order splits it from its parent's block (`applyLegacySessionRank`, `childrenSplitFromParent`); a PUT of the current order, or one that moves a family together, leaves every stored placement alone. The browser never echoes a create or delete through that PUT, with or without groups: the service already re-projects the order and broadcasts it (`session:orderChanged`), and `syncSessionOrder` adopts it. A child whose parent is gone stands on its own and is never re-adopted. Saved web tabs are layout refs like sessions, but OPENNESS stays per device: a grouped web tab renders (and takes an Alt+N slot) only while it is open on this device, and reopens where the layout keeps it.
+- **A case's default session group** (`caseDefaultGroups` in state.json, keyed by the layout owner key then case name; a group id or `null` for Ungrouped) is the fallback placement for a new session of that case. It is read and written ONLY through `TabLayoutService` (`caseDefaultGroup`, `setCaseDefaultGroup`, `forgetCaseDefaultGroup`, and `sessionCreated`'s `caseName` hint), under the owner lock, never by a route or the store directly. Precedence inside `sessionCreated`'s single write: an explicit `tabGroupId` found in the owner's layout, then a parent that places the child (`hasPlacingParent`, the same conditions as `pinCreatedChild`), then the case default, else normal placement. The id is looked up in the creating owner's own layout, so a deleted or foreign id never fails a spawn; a stale id is forgotten only AFTER the creating write lands (a failed write rolls back and changes nothing). `POST /api/quick-start` and `POST /api/ralph-loop/start` pass their `caseName`; `POST /api/sessions` infers it LEXICALLY from `workingDir` (`inferLocalCaseName`: a direct child of the caller's case space, or an exact linked-case path for an admin or single-user, or a Claude worktree of either, `<case>/.claude/worktrees/<name>`, which is how the Git worktrees modal launches Claude while every other CLI goes through quick-start), only for a named `workingDir` (never the server's own cwd), never for a remote attach and never touching the filesystem. Cron jobs, the one-shot run route and reboot restore keep normal placement. The Case settings selector (`onCaseDefaultGroupChanged`, session-ui.js) reads it on popover open and is redrawn from an adopted layout whose groups changed (`_refreshCaseDefaultGroupOptions` in `_applyTabLayout`; an unchanged group list is skipped, since every create, delete and reorder broadcasts a layout and a rebuild would reset an open dropdown).
 - **Only the grouped rail is a tree.** `#sessionTabs` ships as `role=tablist` with `role=tab` rows, and the header strip, sidebar and flat rail keep exactly that. While grouped, `_applyTabListRole` makes it `role=tree` (and restores `tablist` + its label when grouping ends), named-group headers are level-1 `treeitem`s that `aria-owns` their rows' `role=group` (rows sit beside the header, not inside it), and ungrouped rows plus a collapsed group's kept selection are level-1 items. A collapsed header owns nothing, a group with no open rows is a leaf (no `aria-expanded`, no owned group), and the "Ungrouped" heading is `aria-hidden`. Rows are re-roled in the DOM by `_applyTabTreeSemantics` after render, never by rewriting their markup, so a grouped row's content stays the flat row's.
 - **One tab stop in the tree.** Exactly one treeitem carries `tabindex=0` (the focused or selected item); every control inside a row drops to `-1`, which is why Shift+F10 / ContextMenu open a row's actions from the keyboard. Focus survives a full re-render by identity (`group:`/`session:`/`webview:`; a row a collapse just hid hands focus to its header), but only when focus was already inside the rail. The tree walk (`_tabTreeItems`) follows painted order WITHIN each group when the rail is sorted; the flat list keeps its own whole-list computed-order walk. `aria-posinset`/`aria-setsize` follow painted order too, so the incremental render path re-runs `_applyTabTreePositions` after it re-sorts rows in place. ⚠️ `_handleTabTreeKeydown` acts only when the key lands on the treeitem ITSELF: a key on a focused in-row control (close, overflow, the rename input) is that control's, or Enter on the overflow button re-selects the row instead of reopening its menu. ⚠️ The roving `tabindex=-1` also hides every item but the stop from the keyboard-dismiss selector's `[tabindex]` arm, which is why `MOBILE_KEYBOARD_DISMISS_EXEMPT_SELECTOR` lists `[role="treeitem"]` (see Dismissing the on-screen keyboard).

That is Claude Code's own `--worktree` layout (measured in 2.1.296: same path, branch `worktree-<name>`, names of `[A-Za-z0-9._-]`, at most 64), and Codeman's names are a strict subset of Claude's.

A worktree anywhere else is listed read-only (`managed: false`). A managed worktree whose folder is GONE stays removable (`resolveManagedWorktree({ allowMissing })`, removal only, never a session start: git lists it at exactly the managed path, no component on the way is a symlink, and `git worktree remove` then only drops git's record), since otherwise its name could never be used again.
+- ⚠️ **git never runs for a case at or inside a Docker case workspace** (or whose common git dir is there), and Docker and remote cases are refused with a 400 before any git, the same rule as the git status indicator: `git worktree add` runs the repository's post-checkout hook and checkout filters ON THE HOST. That is acceptable for a local case, where the user's agent already runs code. A managed worktree that is, sits inside, or holds a Docker case workspace (a Docker case linked to the worktree folder) is never removed (400): `git worktree remove` runs a status inside the tree and then deletes it, ignored files included, under the container.
+- ⚠️ **Removal is `git worktree remove` WITHOUT `--force`**, refused (409) while any live session (any owner) runs at or inside the worktree, and git's own refusal (modified or untracked files, a lock) is the answer, shown through `textContent`.

+- ⚠️ **The main checkout must not see the worktrees.** When `git check-ignore` says they are not ignored, `/.claude/worktrees/` is appended to the repository's LOCAL `<common git dir>/info/exclude` (never a tracked `.gitignore`), and so is `/.claude/settings.local.json`: Codeman writes its hooks there for every claude session, and an untracked copy in a worktree would make `git worktree remove` refuse forever (Claude Code covers that file with the global excludes file, which a machine may not have). The agent skill copy (`<skills dir>/codeman/`, injected while `agentSkillEnabled` is on) gets a line too, for every skills folder the registry names (`capabilities.agentSkillDir`, passed in by the route as data). A symlinked `info` dir or `exclude` file is reported, never written through.
+- **Names are gated before git**: charset and length (Zod and `worktreeNameError()`), then `git check-ref-format --branch`, whose output must EQUAL the input (`--branch` expands `@{-1}`, which the charset gate already refuses). The base is a resolved commit (`rev-parse --verify <base>^{commit}`), passed after `--` with `--no-track`; an existing branch is refused (`-b`, never `-B`, which would reset it). Create and remove are serialized per repository.
+- **Sessions start through the EXISTING create paths**, never a new spawn path: `POST /api/quick-start` with `worktree` (resolved with the same guards; hooks, the agent skill, the model override and the session all target the worktree, and a case that does not exist is a 404, never a scaffold), or `POST /api/sessions` with the worktree as `workingDir` (what the Run button uses for claude and shell). The frontend launches through `run({ worktree })` with a temporary `_runMode` swap, tabs named `w<n>-<worktree>`.

 **Ultracode / Workflow-run visualization** (opt-in `showUltracodeAgents`, default OFF; released 1.1.2): the Workflow tool ("ultracode") writes a COMPLETION artifact per run at `~/.claude/projects/<projHash>/<sessionUuid>/workflows/wf_*.json` (written only at run end); LIVE in-flight runs exist only as transcript dirs at `…/subagents/workflows/wf_<id>/` (journal.jsonl + `agent-*.jsonl`). `workflow-run-watcher.ts` (STANDALONE — deliberately never imports/touches `subagent-watcher.ts`; separate singleton, though it independently reads the same `subagents/workflows/` tree) scans BOTH sources via periodic poll + per-directory chokidar watchers with per-source mtime skip (LRU agentStatCache + journalCache), synthesizing ACTIVE runs (live per-agent tokens/tools/state from transcripts, title/phases from the workflow script) until the completion `wf_*.json` appears and supersedes, and broadcasts SSE `workflow:run_discovered`/`run_updated`/`run_removed`. The watcher is started when **either** `showUltracodeAgents` **or** `ultracodeFloatingWindows` is on (`server.ts` `isWorkflowAgentTrackingEnabled()` returns `(showUltracodeAgents ?? false) || (ultracodeFloatingWindows ?? false)`). Served via `GET /api/workflows` (optional `?minutes=` filter) and `GET /api/workflows/:runId`. Frontend `ultracode-panel.js` renders a docked master-detail view (LEFT: runs + phases; RIGHT: per-agent tokens + tool-calls; click an agent card → its live transcript via client-side `agentId` join). **Additionally**, `ultracode-windows.js` auto-pops a draggable **floating window per active run** (gated on a **DEDICATED** `ultracodeFloatingWindows` toggle, default OFF — independent of the dock panel's `showUltracodeAgents`; see `_ultracodeFloatingEnabled()`), connected by a glowing line to the originating session tab (resolved by `session.claudeSessionId === run.sessionUuid`) — same line idiom as subagent windows, drawn into the shared `#connectionLines` SVG from the tail of `_updateConnectionLinesImmediate`. The window auto-closes ~8s after its run finishes; explicit dismissals are remembered. Clicking an agent card opens an **in-page** connected transcript window (not a browser popup); both run and transcript windows minimize **into** the originating session tab as a merged `ULTRA` badge (🧬 runs / 📄 transcripts) with a restore/dismiss dropdown — minimized runs are skipped by auto-pop. Gesture beta: floating subagent/ultracode windows are pinch-draggable (a `window` grab kind in `entry.ts`). Types: `src/types/workflow-run.ts`. Config: `src/config/workflow-config.ts`.

 1. **Root-absolute URLs built at runtime.** `<base href>` only governs URLs the HTML parser resolves; `fetch('/api/data')` bypasses it and lands on Codeman's root. That is how most dashboards talk to their own backend. The `Referer`-keyed 404 fallback is only a rescue (it fires after every real route missed, and only when the browser sends a usable `Referer`), so the fix is `runtimeUrlShim()`: a small script injected right after `<base>` that rebases root-absolute and same-origin-absolute URLs into the prefix. It removes the whole class inside the iframe instead of trading security for it. ⚠️ It must be injected even when the page ships its OWN `<base>` (an early return there silently breaks exactly the pages that need it most). ⚠️ **The DOM sinks are as load-bearing as `fetch`.** Patching only `fetch`/`XHR`/`WebSocket`/`EventSource` leaves `container.innerHTML = '<img src="/api/hero?slug=x">'` and `img.src = '/api/slide'` untouched, and neither of the other layers can reach those either (`<base>` never applies to root-absolute URLs, and `rewriteHtml()` only ever sees the INITIAL document, never markup built later by page script). The symptom is precise and easy to misdiagnose as an upstream fault: the dashboard's **data** loads while every **image** stays broken. So the shim also wraps `innerHTML`/`outerHTML`/`insertAdjacentHTML`, `setAttribute`/`setAttributeNS`, and the `src`/`srcset`/`href`/`poster`/`data`/`action` property setters, with a `MutationObserver` as a last net for sinks not patched above. Every rewrite routes through the same idempotent `rw()`, which matters because unlike the server-side rewrite this one sees markup that may ALREADY be proxied (a page re-injecting its own `outerHTML` would otherwise double-prefix). The DOM half is pinned in jsdom by `test/webview-proxy.test.ts`; `curl` cannot see any of it.
 2. **CORS on same-host requests.** An opaque-origin document treats EVERY request as cross-origin, including to the very host it was served from, so its `fetch`/XHR are CORS-checked and its preflights carry `Origin: null`. Static subresources (script/css/img) are NOT CORS-checked, which is why the page renders while its API calls die with an opaque `net::ERR_FAILED`. `buildProxyCorsHeaders()` echoes the origin (omitting `allow-credentials` for `null`, which browsers reject in combination), upstream `access-control-*` headers are dropped (they describe the dashboard's origin, not the frame's), and the proxy answers preflights itself rather than relaying them. ⚠️ `registerSecurityHeaders` answers EVERY `OPTIONS` with a bare 204 before routing, and its CORS block only emits headers for localhost origins, so that short-circuit **must** exempt a valid webview capability or every preflight fails. `curl` cannot reproduce any of this because curl does not enforce CORS.

-**Fastify specifics.** The proxy lives in an **encapsulated plugin scope** with `removeAllContentTypeParsers()` + a `'*'` pass-through parser, so raw bodies relay byte-for-byte while the root instance keeps its JSON parsing (and keeps `text/plain` RAW, which was a real CSRF hole once). One `app.route({ method:'GET', handler, wsHandler })` serves both HTTP and the WebSocket upgrade; **HEAD must NOT be declared** on the sibling route because `exposeHeadRoutes` already derives it and the duplicate is a startup error. ⚠️ **Every exit path in the proxy handler RETURNS `reply.send(...)`**: the handler is `async`, and a bare `return` after `reply.send(stream)` resolves the handler promise to `undefined` before the stream is consumed, so Fastify answers with an EMPTY body. HTML survives that (synchronous string payload) while every streamed asset comes back zero-length, which is a genuinely confusing failure.

 **Frontend** (`src/web/public/webview-tabs.js`, load order 12.5): web tabs render into `#sessionTabs` carrying `data-webview-id` instead of `data-id`, so every session-tab path (drag-and-drop, alerts, badges) skips them. ⚠️ `_renderSessionTabsImmediate()`'s `canIncremental` check must include the web-tab comparison: the session-only comparison is vacuously "unchanged" whenever session count is stable, most visibly at ZERO sessions (`0 === 0`), where opening a dashboard would never draw its tab. ⚠️ `isActive` for a session tab is `id === activeSessionId && !activeWebviewId`: `activeSessionId` stays set while a web tab is showing (the terminal keeps streaming underneath), so without that clause the debounced re-render lights two tabs at once. Frames stay MOUNTED while hidden (LRU-evicted past `maxLiveFrames`) so tab switching never reloads a dashboard.

With an explicit `--parallel N` llama.cpp reports `n_ctx` per slot, so a `/props` context beside it is stored with a slot count of 1: it is not divided a second time, and the 1 overwrites a count an earlier discovery round stored (`applyDiscoveredModels` merges onto what was learned before, so recording no count would keep the stale one).

+### Config backups
+
+**Config backups** (`src/config-backup.ts`, pure over the directories it is handed; `routes/config-backup-routes.ts`; the Config backups group in App Settings → System, `settings-ui.js`; contributed in #661, user guide `docs/wiki/Config-Backups.md`, endpoints in `docs/api-reference.md`): timestamped snapshots of the files that hold what a user customized, so a bad write can be undone. Settings (SYNCED): `configBackupEnabled` (absent = ON, since it protects against an event nobody schedules), `configBackupDir` (absolute, `~` expanded; empty, relative or the data dir itself = `<data dir>/backups/config`), `configBackupKeepCount` (2 to 500, default 20), `configBackupKeepDays` (0 to 3650, default 30, `0` = no age limit). A snapshot is a `cfg-YYYYMMDD-HHMMSS` folder (server local time, `-2`, `-3`… on a same-second collision; mode 0700) holding the tracked files under their own names plus a `manifest.json` (all 0600): `id`, `createdAt`, `reason` (`startup`/`auto`/`manual`/`pre-restore`), `appVersion`, the change-check `hash`, the `origin`, the `keepCount`/`keepDays` in force, and a SHA-256 and size per file. It is built in a `.tmp-cfg-*` folder and renamed into place; a pass sweeps temp folders older than an hour. Passes run at startup and every 5 minutes (`CONFIG_BACKUP_INTERVAL_MS` in `server.ts`, not in test mode), and on **Back up now** (forced).
+
+⚠️ **The tracked list is a fixed allowlist** (`CONFIG_BACKUP_FILES`), never "everything in the data dir", and restore writes only those names whatever a manifest lists. `state.json` is deliberately NOT tracked: it is rewritten on every session event, so it would make a snapshot per event and bury the real changes. It also holds cron jobs and respawn presets, which is the documented gap.
+
+⚠️ **One snapshot per real change.** The change check compares a digest of the file set with the newest manifest's `hash`, looking through `VOLATILE_KEYS`, fields a tracked file rewrites on its own: `custom-model-hosts.json` `lastDiscoveredAt` (the discovery poll), `users.json` `lastLoginAt` (every Basic login), `settings.json` `lastUsedCase` (a session started in another case), `intents.json` `recentPrompts`/`updatedAt` (every captured prompt), `docker-cases.json` `lastClaudeSessionId` (a `/clear` in a Docker case) and `webviews.json` `lastOpenedAt` (opening a web tab). Each was found the same way: one tick-driven rewrite made a snapshot per tick, and the 20 kept copies covered about 95 minutes. A new self-rewritten field in a tracked file needs an entry there and a row in the `it.each` table of `test/config-backup.test.ts`. The snapshot still stores the bytes and restore verifies the raw digest; only the comparison looks through these keys (so Compare calls `intents.json` unchanged when only prompts differ, yet a restore drops the prompts captured since).
+
+⚠️ **Retention deletes only what this module made, and never the newest snapshot.** A folder counts only with the name pattern AND a parseable manifest of this origin, so a custom folder that also holds other things is safe to point at. A snapshot is aged from its SUCCESSOR's `createdAt` (its state was live until the next one was made): aging it by its own date deleted the last good copy on the first change after a quiet month, which is exactly the bad write the feature exists for. The keep count floor is 2 (`CONFIG_BACKUP_MIN_KEEP_COUNT`), since 1 deletes the state before every change. A new snapshot is never dated earlier than the newest one (`createdAt + 1`): one written while the clock read ahead (dual boot, a VM resumed with a stale clock) stayed newest after the correction, differed from every later pass, and made each one write a copy until real time caught up. The flip side, a clock once set to a future year, is a Troubleshooting entry (delete the future-dated folder).
+
+⚠️ **The origin is a random id in `<data dir>/config-backup-id`, never the hostname.** Instances that share a folder (two machines on one synced folder, prod and a beta) must keep to their own snapshots, so the change check, list, prune, Compare and restore are all scoped to it; without that, each instance snapshotted on every tick and Restore offered the other machine's `users.json` and `.env`. The hostname was tried first and was wrong: a Docker Compose container gets a new one on every recreate, which unlisted every earlier snapshot, and since prune is origin-scoped they were never deleted either. The id is not the hook secret and is never tracked or restored. Listing never creates it (`readConfigBackupOrigin()`; only a pass or a restore does). A fresh or reinstalled data dir is a new owner; copying an `origin` from an old manifest into the file makes those snapshots visible again.
+
+⚠️ **Retention survives a bad `settings.json`.** Each manifest records the retention in force. `runConfigBackup()` reads `settings.json` itself, because `readJsonConfig` answers `{}` for any failure, including a read that lands inside the non-atomic write of `PUT /api/settings`: a file that does not parse still gets its snapshot but prunes nothing, and a retention key ABSENT from the file (a reset) means what the newest manifest that recorded one holds (`withRecordedRetention()`, per key, in the folder the file names, so re-entering a custom folder after a reset finds that folder's own history). `GET /api/config-backups` reports the same values the pass uses, the form fills from them, and Save sends a retention key only when it was saved before or edited there (`_configBackupRetentionPayload()`), so merely displaying the recorded retention never writes it back. Restoring `settings.json` keeps the four `configBackup*` keys at their live values (an old `configBackupDir` would point the list at another folder and hide the undo copy just made), except a retention key the live file lacks, which keeps the backup's. While `settings.json` does not parse a pass reads it as `{}`, so its snapshot goes to the default folder; nothing is widened.
+
+⚠️ **A custom folder is probed BOUNDED before anything reads it** (#516: it may be a network mount that stopped answering, and the GET runs every time App Settings opens). `probeBackupDir()` runs `probePathKind(dir, { pastCap: true })` before every pass and in every route, and `readEffectiveBackupSettings()` probes BEFORE the recorded-retention fallback lists the folder (that fallback once did a `readdirSync` first whenever only `configBackupDir` was set). `unknown` answers 503 `OPERATION_FAILED` through `describeUnknownPath()` and skips the pass; a missing custom folder is created only when its parent is present. The default folder needs no probe. `test/routes/config-backup-unreachable.test.ts` pins all four routes with a recording `node:fs` mock.
+
+⚠️ **One walk of the folder per pass.** `runConfigBackupPass()` reads the folder once and hands the names to the temp sweep and the manifests to the retention fallback, the change check and the prune (with the snapshot it just made prepended: it is always the newest, by the date floor above). Each of the three used to list the folder itself, so every manifest was read three times per pass, every five minutes, on what may be a network folder; restore lists once too. `test/routes/config-backup-one-walk.test.ts` counts the reads.
+
+⚠️ **Restore verifies everything before it writes anything.** Every file's SHA-256 against the manifest, and the id must match the name pattern (no traversal); a mismatch is a 409 with nothing changed. It also refuses a snapshot folder or file that is a symlink or has a group/world bit: this module only ever writes 0700/0600 real files, so such a thing was planted or loosened later, and rewriting it as 0600 would turn it into trusted config (`clis.json` selects the binaries Codeman spawns; `isUnsafePermissions` refuses the same bits there). The mode test is skipped where the filesystem keeps no modes (vfat/exFAT, CIFS, WSL `/mnt/d` without `metadata` report 0755/0777 for everything, and Restore would refuse every backup there): `folderKeepsModes()` decides by creating a 0600 probe file with a random name and `wx`, because the earlier fixed `.mode-probe-<pid>` name let a planted symlink be truncated and chmodded by one Compare click. Compare applies the same checks to the snapshots it reads.
+
+⚠️ **The undo copy comes first, and a partial restore is reported, never hidden.** A `pre-restore` snapshot of the live files precedes the writes; it is not forced, so when nothing changed since the newest backup that backup is the undo copy and is the one reported (a forced copy spent a retention slot on a duplicate). It records the retention in force, so it cannot hide that retention from the next pass. Each file is replaced atomically (temp + rename, 0600). A file that cannot be written (a full disk, a directory in its place) does not stop the others: `ConfigBackupPartialRestoreError` carries `restored`, `failed`, `untouched` and `safetySnapshot`, and the route answers 500 with the error envelope plus those fields (and `restartRequired`) in `data`, the shape the tab-layout 409 uses. The bare 500 it replaced named neither the files already put back nor the undo copy.
+
+⚠️ **What a restore wrote must reach the running server**, on the full and the partial path alike (`afterRestore()` in the route): `intentStore.reload()` (the store caches `intents.json` and rewrote it whole on the next captured prompt, reverting the restore), `reloadCliRegistry()` (a restore of `clis.json` is the one write that bypasses `mutateRegistryFile()`, see CLI registry), and in multi-user mode a `config_backup_restore` admin-audit entry (`users.json` holds accounts, password hashes, roles and bypass grants). `users.json` itself is re-read within a second by the user store. `.env`, `push-keys.json` and `settings.json` (whose watcher toggles only `PUT /api/settings` runs) apply after a restart: `RESTART_REQUIRED`, returned as `restartRequired`. Settings re-reads `/api/settings` into the form after any restore that wrote `settings.json`, partial ones included, because the form still holds the old values and the next Save would PUT them over the restored file.
+
+⚠️ **Compare never returns a credential.** `REDACT_ALL_FILES` (`.env`, `users.json`, `push-keys.json`, `webhook.json` whose URL is a bearer secret, `intents.json` whose prompts carry secrets) report changed key names only; anywhere else a key matching `SECRET_KEY_RE` (token, secret, password, credential, auth, `*key`) is reported as changed without its value, and URL values lose userinfo, query and fragment. Listing returns file names and sizes only.
+
+⚠️ **Admin only in multi-user mode**: all four routes answer 403 for a non-admin and the Settings group is hidden for them (`_applyDoctorAdminGate()`), because the files include credentials.

Defaults are deliberately not gated (Ctrl+L must reach the CLI for its redraw), so the gate also skips an entry re-captured onto its own default, `toggleSessionSidebar` (it has its own gate, `shouldToggleSessionSidebarFromShortcut`) and copy-selection. Capturing, re-enabling and Reset all go through `findShortcutConflict`/`findShortcutBindingConflict` (settings-ui.js); Alt+1-9, Ctrl/Shift+Enter and Ctrl/Cmd+V are reserved there.
 
 **A key gate on a chord that can carry Shift alone must swallow the KEYPRESS too** (#520). xterm calls the custom handler from `attachCustomKeyEventHandler` for `keydown`, `keypress` AND `keyup`, and its own `_keyPress` drops a keypress carrying Ctrl, Alt or Meta but not one whose only modifier is Shift. So a gate that returns `false` for `ev.type === 'keydown'` alone is safe for a Ctrl or Alt chord (the palette's Ctrl+K, Alt+B, Ctrl+V, Ctrl+Z and the keydown-only smart copy below) and leaks for a Shift-only one. That is how Shift+Enter submitted the prompt from April to #520: its keypress fell through to `onData` as a bare `\r`, which goes out synchronously over the WebSocket ahead of the async `send-key` fetch, so the CR reached the PTY before the newline did. Ctrl+Enter worked all along only because Chrome fires no keypress for it. ⚠️ The Shift/Ctrl+Enter gate in terminal-ui.js and its twin in Pane B (terminal-split.js) return `false` for EVERY event type and key only the `send-key` POST on `keydown`; never narrow either back to keydown, and give any new Shift-only chord the same shape. Swallowing the keyup as well is harmless (xterm only skips a focus and cursor-style refresh for that one event). Tests: `test/shift-enter-keypress-swallowed.test.ts` (CI gate, a source guard on both files) and `test/shift-enter-keypress.browser.test.ts` (browser suite, which the gate does not run: real keys against both real handlers in the real app). Settings → Terminal & Input → **Key tester** shows what a device reports for each of the three events.

Three guards are load-bearing and each came from a real phone: the compat mouse pair after `touchend` (xterm focuses on mousedown and SelectionService resets the model there, so the keyboard sprang up and the selection vanished on lift), the platform's own ~500ms long-press (Android Chrome focuses the nearest editable element — the helper textarea — through no event a handler can preventDefault, so a bounded focus guard blurs it and `contextmenu` is suppressed for the gesture window), and `copyTerminalSelection()`'s closing `terminal.focus()` (right on desktop, wrong on a phone).

+⚠️ **A sideways drag belongs to the session swipe**, never to a tap or a scroll. The touch handler locks the dominant axis on the first travel past the tap slop (`panAxis`: `y` scrolls the buffer, `x` pans a terminal wider than its box, `swipe` when it cannot pan) and publishes it per gesture as `app._terminalGestureAxis`; a `swipe` drag is consumed without scrolling and never ends as a tap, which used to activate a link, a CLI click or a keyboard toggle on the session being left. ⚠️ Only up to the swipe's own drift limit (`SwipeHandler.maxVerticalDrift`): past it the swipe has given up, so the drag is handed back to the scroll (`y`). Otherwise a scroll whose first few pixels lean sideways (a thumb arc) locked as `swipe` and did nothing at all. `SwipeHandler` (mobile-handlers.js) reads that axis and stands aside for `x` and `y`, for a touch selection, after a second finger, and on surfaces with controls of their own (`IGNORE_SELECTOR`: the tile grid, the selection bar, the CJK input, the history banner); the phone overview and the welcome screen are deliberately not listed, since swiping from home into a session is a feature. A swipe is 80 px of travel within 500 ms (300 ms rejected an unhurried but deliberate swipe outright) with at most 50 px of vertical drift at any point: `touchmove` cancels it mid-gesture rather than only at the lift. Two more rules came from walking the sequences: a touch that starts outside the terminal (a swipe over the home screen) resets the published axis, so a terminal scroll a moment earlier cannot veto it, and a lift the terminal consumed (`defaultPrevented`: its long-press selection gesture, which on blank space leaves no selection behind to check) is never a swipe; the second-finger cancel stays set until the next touchstart, so the first finger lifting cannot clear it.

Letting the tap blur the terminal and refocusing it afterwards made every such key start a keyboard dismissal, a blur/focus pair per tap that shifted the toolbar each time.

The pre-move `.claude-images/` receives nothing but stays readable for one release: `UPLOAD_DIR_NAMES` lists both, the hourly sweep and the delete cleanup in `cleanupSession()` go through `uploadDirs()`, and the image watcher's ignore filter reads the names. ⚠️ `uploadDirs()` is async: the working directory is a user-chosen path, so it is probed BOUNDED first (`probePathKind()`, the #516 rule; `unknown` is skipped and never touched, the hourly sweep keeps the stall cap and `cleanupSession()` passes `pastCap`, since it acts on one path at the user's request), and the lstat and realpath after it are `fs.promises` calls, never sync, because the sweep runs 30 s after boot and hourly over every live session and a linked case on a dead mount would otherwise freeze the whole server. It returns only REAL directories (lstat at the leaf, so a planted `.codeman-uploads -> /other-case/.codeman-uploads` is never listed: `readdir` follows a link to a directory, and the sweep would otherwise age out the other case's uploads through it), none that is or contains `getDataDir()` (contrived, `CODEMAN_INSTANCE=uploads` makes `~/.codeman-uploads` the data dir of a home workspace and `CODEMAN_DATA_DIR` can point inside one, but it is one check next to a recursive delete; one strictly INSIDE the data dir is listed, since it only ever holds uploads and a workspace like the `~/.codeman/app` that `install.sh` clones would otherwise never have its uploads collected), and nothing for a remote (SSH) session, whose `workingDir` is the remote path and would otherwise name a same-named LOCAL directory for the sweep and the delete. The check is made when the directories are listed: a same-user process that swaps a listed directory for a link during the sweep's awaits is accepted (Node has no `openat()`, and that actor already writes anywhere this process can). The route refuses a remote (SSH) session with 400 before any disk touch: its `workingDir` is the remote path, so the file would land on THIS host where the agent cannot read it. ⚠️ And because a live session's workspace can go onto a network mount that later stops answering, the route probes `session.workingDir` BOUNDED (`probePathKind(..., { pastCap: true })`) before the first disk touch, refusing an `unknown` mount through `describeUnknownPath()` (OPERATION_FAILED) exactly as `POST /api/sessions` does, so a mount already unreachable cannot freeze a libuv worker on every upload (`ensureUploadDir()`'s own lstat/mkdir then start on a reachable path; a mount that dies between the probe and that write is the same residual race `POST /api/sessions` accepts, since a pre-check cannot bound the write that follows it).

+IDLE prompt from a codex session ever reaches the approvals inbox (its screen-read dialogs,
+below, open PERMISSION items, which a watching label never acknowledges), so a forged label
+costs a wrong badge and cannot silence an alert. Before giving a CLI idle signals and a
+pattern, make sure its row is one the agent cannot write.
+
+### Dialogs a CLI blocks on (`blockedLine`)
+
+`blockedLine` is the screen-read source of the `blocked` state for a CLI with no hook to
+report it. Codex is the reason it exists: it is the one CLI Codeman launches with its
+approvals on by default, and with `hooks: 'none'` a codex session parked on "Would you like to
+run the following command?" used to read as plainly idle, and one parked on a question as
+WORKING (the question's own key hints end in `esc to interrupt`, codex's working line). A
+pane matching it is BLOCKED, which raises exactly what a Claude `permission_prompt` hook
+raises: the red "needs you" tab alert and desktop notification, web push and webhooks, the
+phone overview's NEEDS YOU row, an Approvals Inbox item, a run-summary row and the `blocked`
+wait signal (`web/screen-blocked.ts`). `stop` stays unavailable for such a CLI: nothing on a
+screen says a turn ended.
+
+The pattern runs over the last `blockedLines` (1 to 24, default 1) non-blank rows, joined
+with newlines and tested once (`isBlockedScreen()`, `session-activity.ts`), so it can demand
+several markers and anchor the dialog's footer on the END of the window (no `m` flag: `$` is
+the last row). Codex's needs a `› N.` option row and then its key-hint row (`Press enter to
+confirm or esc to cancel`, `tab to add notes | enter to submit answer | esc to interrupt`,
+`enter continue · esc quit` for the startup trust prompt, `esc back` when it follows the
+update prompt), allowing for that row to wrap onto rows of its own below about 60 columns.
+Measured on codex-cli 0.162.0 at widths 200 down to 36: the command, edit and
+network-escalation approvals, single and multi-question
+`request_user_input` dialogs (notes field open or closed), and the workspace trust prompt
+match; the idle and working views, popups the user opened (`/model`, `/permissions`,
+`/review`), the composer holding the dialogs' words and a transcript quoting them verbatim
+do not. `Implement this plan?` after a plan turn is deliberately not matched: its footer is
+the same as `/model`'s, and the turn has ended there. The fixtures are in
+`test/fixtures/codex-dialogs/`.
+
+Three rules hold for any CLI that declares one:
+
+- ⚠️ The text is pane-derived and the agent writes most of the pane, so the pattern must end
+  on chrome only the CLI draws, at the foot of the screen, where a dialog replaces the
+  composer. A match is an ALERT and nothing else: the inbox item is `answerInTerminal`, the
+  answer route refuses it, push offers no Approve/Deny, and Codeman never answers such a
+  dialog itself, so a forged match costs a false alert and never a keystroke.
+- The state raises on one reading (the session's settle probe, which reads the screen once
+  the pane goes quiet, which is when a dialog has just been drawn), and while it is up a timer
+  re-reads the screen every 2 s (`BLOCKED_RECHECK_MS`), because answering resumes the turn and
+  a busy pane would not reach the settle path again until the turn ended. The read is skipped
+  while the pane has drawn nothing since the last reading that saw the dialog (a dialog leaves
+  only through a repaint), with a safety-net read every 30 s (`BLOCKED_QUIET_RECHECK_MS`), so a
+  dialog left unanswered for hours does not cost a synchronous `tmux capture-pane` every 2 s.
+  It clears only after
+  two readable captures in a row without the dialog (`BLOCKED_CLEAR_READS`), so a capture
+  taken mid-repaint cannot clear and re-raise it (a second alert, push and webhook for one
+  dialog). An unreadable capture changes nothing in either direction. A blocked screen wins
+  over the working line in the same capture.
+- Hooks win: a session whose CLI reports blocked itself (`hooksAvailableForMode()`) gets
+  nothing from the screen, so declaring both can never alert twice for one dialog.
+
+A `GET /api/sessions/:id/wait?until=blocked` that arrives while such a dialog is already up is
+answered at once (`immediate: true`): unlike a hook's edge, this is a level the server is
+still reading. A caller that asked only for `idle` keeps getting `idle`.

+## GitHub Copilot CLI
+
+`copilot` (npm `@github/copilot`) is a stock entry. A bare launch is `copilot`, in its own Manual Approval mode. The launch parameters follow the grok/omp shape: `model` (`--model`), `resumeId` (`--resume <id>`, an id, id prefix or session name: a single word that starts with a letter or digit, so a flag-shaped value such as `--yolo` is dropped rather than read as its own flag) and `continueSession` (`--continue`, skipped when a resume id is set), plus `allowAll` (`--yolo`: allow every tool, path and URL). The legacy config object is `copilotConfig` (`{ model, allowAll, resumeSessionId, continueSession }`). The Run button sends `allowAll: true` like the other agent CLIs' bypass switches, and `allowAll` is declared in `privilegedParams`, so a non-granted multi-user owner has it forced back to `false` (an absent config is never materialized: a bare spawn is already safe). Session history resume (Past Sessions) sends only `copilotConfig.continueSession`, which continues the most recent conversation Copilot has for that directory; `resumeSessionId` is for API callers. The tab names the model it reads from the footer (`modelDetect`). Its `altScreen` is `strip-mux-and-mouse`, like opencode: Copilot turns mouse tracking on itself, and left in, a plain drag is reported to the TUI instead of selecting (Auto Copy and copy-on-select did nothing); stripped, a drag is a local selection, clicks go through the hand-encoded tap, and the wheel is forwarded as SGR reports while `cliMouseTracking` is on. It declares `mcpConfig` (`~/.copilot/mcp-config.json`, relocated by `COPILOT_HOME`) and no `credStore`: its token sits in `config.json` in plain text on a host without a keyring, so a Docker case is not seeded and you sign in inside the container. `env.allowedKeys` is empty on purpose: a headless host sets `COPILOT_GITHUB_TOKEN`, which the `COPILOT_` prefix admits, and `GH_TOKEN`/`GITHUB_TOKEN` stay out of the one global allowlist. **Plan usage:** the header chip gains a `Copilot` row with one `mo` window, the calendar-month premium-request quota (`quota_snapshots.premium_interactions` from `GET api.github.com/copilot_internal/user`, an undocumented endpoint the editors use; the tooltip also shows the request counts and reset). It is polled every 10 minutes by the host, read-only, and only when the CLI is installed, a token resolves (`COPILOT_GITHUB_TOKEN`, `GH_TOKEN`, `GITHUB_TOKEN`, then `authTokens` in `<COPILOT_HOME or ~/.copilot>/config.json`) and plan-usage display is on. Any failure leaves the chip without a Copilot row; an unlimited quota has nothing to meter and is omitted.
+
+Measured on 1.0.94 inside tmux: an alternate-screen TUI with mouse tracking on, whose composer is the `❯` between two rules. While a turn runs the footer reads `◉ Working esc edit prompt` (the dot alternates `◉`/`◎`), which is the `workDetect` working line. Keystrokes sent with `tmux send-keys` reach the composer, Shift+Enter inserts a newline, and a shell tool call completes inside tmux; github/copilot-cli#4180 (a driven PTY ignores input) and #4223 (a shell command never completes under tmux) report both failing on 1.0.70 to 1.0.74 and neither reproduces on 1.0.94. `COPILOT_HOME` and `COPILOT_ALLOW_ALL` are privileged env keys, so a non-granted multi-user owner cannot set them through `envOverrides`, and so are the other `COPILOT_*` variables (read from the 1.0.98 bundle, far more than `copilot help environment` lists) that switch approvals, run code with no approval row or send the sign-in token elsewhere. The `COPILOT_` prefix admits whatever a later release adds, so the list needs a look whenever the measured version moves.

+# GitHub Copilot CLI sessions
+
+Codeman can drive [GitHub Copilot CLI](https://github.com/github/copilot-cli) (`copilot`,
+npm `@github/copilot`) as a session backend, alongside Claude Code, OpenCode, Codex, Gemini,
+Antigravity, Pi, Grok, DeepSeek Harness and OMP. `copilot` is a run mode: its own PTY, its
+own tmux session, its own tab identity (purple, a drawn mark rather than GitHub's logo). It is
+not a location overlay like Docker or remote-SSH cases, and it is not a web tab.
+
+Everything here was measured against Copilot CLI 1.0.94 and 1.0.95 inside tmux. The entry
+itself is registry data (`src/config/cli-registry/stock.ts`); see
+[`cli-registry.md`](./cli-registry.md#github-copilot-cli) for the field-by-field reference.
+
+## Install
+
+```bash
+npm install -g @github/copilot
+```
+
+CLI management (Settings → Agents & CLIs) can run exactly that for you. Codeman resolves the
+binary from the server's PATH and the usual npm/nvm prefixes, then runs `copilot --version`
+and accepts it only if the output says `GitHub Copilot CLI <x.y.z>`. A bare `copilot` on PATH
+that answers anything else is ignored. Check what it resolved:
+
+```bash
+curl -s localhost:3000/api/copilot/status | jq
+# { "available": true, "path": "/home/you/.local/bin", "version": "1.0.95" }
+```
+
+## Authenticate
+
+Codeman never logs Copilot in or stores its credentials.
+
+- **Interactive.** Run `copilot` once and use `/login` (or `copilot login`), or do it inside a
+  Codeman tab. The token goes to the OS keychain when one is available.
+- **Headless server.** There is no keychain on a service, so Copilot offers to keep the token
+  as **plain text in `~/.copilot/config.json`** (`authTokens`). That is where it ends up when you
+  accept. To keep a token out of a file, set `COPILOT_GITHUB_TOKEN` in the service environment;
+  Copilot reads it first, then `GH_TOKEN`, then `GITHUB_TOKEN`.
+- **Per-session override.** `COPILOT_*` is the only prefix the env allowlist admits for
+  Copilot. `GH_TOKEN` and `GITHUB_TOKEN` are deliberately **not** accepted as per-session
+  overrides: the allowlist is one global list with no mode context, so admitting them would
+  make them settable on every session. Use `COPILOT_GITHUB_TOKEN`.
+- **No GitHub sign-in is needed** when a session points at your own endpoint (below).
+
+## What Codeman wires up
+
+| Thing | Behaviour |
+| --- | --- |
+| Launch | `copilot`, in Copilot's own Manual Approval mode. |
+| Run button | `copilot --yolo` (allow every tool, path and URL), like the other CLIs' bypass switches, so an unattended session never stops on an approval. |
+| Permission clamp | `allowAll` is a `privilegedParam`. A multi-user owner without the bypass grant has it forced back to `false`; an absent config is never materialized (a bare `copilot` is already safe). `COPILOT_HOME`, `COPILOT_ALLOW_ALL`, `COPILOT_PROVIDER_*` and `COPILOT_MODEL` are privileged env keys, and so is every other `COPILOT_*` variable the CLI reads that switches approvals (`COPILOT_PLAN_THEN_AUTOPILOT`), runs code with no approval row (`COPILOT_CLI_DIST_DIR`, the package caches, `COPILOT_EDITOR`, `COPILOT_PROVIDER_API_KEY_COMMAND`, skills, hooks) or sends the sign-in token to another host (`COPILOT_API_URL`, `COPILOT_GH_HOST`, ...): the list is in `stock.ts`, read from the 1.0.98 bundle. A variable a later Copilot release adds is not covered until it is listed there. |
+| Model | `--model <id>`, sent only by an API caller that sets `copilotConfig.model` (the value must start with a letter or digit, like `resumeSessionId`). Nothing in the UI sets it: a saved custom endpoint sets `COPILOT_MODEL` instead (see below). |
+| Resume | `--resume <value>`, sent only by an API caller that sets `copilotConfig.resumeSessionId` (Past Sessions does not). The value (an id, an id prefix or a session name) must be one plain word starting with a letter or digit: `--resume`'s value is optional, so `--resume --yolo` would otherwise make `--yolo` its own flag and bypass the clamp. |
+| Continue | `--continue`, from **Past Sessions**: it resumes the most recent conversation Copilot has for that directory. Nothing sets it on a respawn. Skipped when a resume value is set. |
+| Name | A tab name **you set yourself** is passed as `--name <tab name>`, so Copilot's own session list reads like that tab. An automatic name (`w1-myapp`, or an auto-named title) is not pinned. Copilot refuses `--name` with `--resume`/`--continue`, so it is dropped there and a continued session keeps the name it had. |
+| Working / idle | The footer. A turn shows `◉ Working esc edit prompt` (the dot alternates `◉`/`◎`); the composer is the `❯` between two rules. A tool waiting for approval replaces the composer and reads as idle. |
+| Model detection | The right-hand field of the footer's last row, at rest and mid-turn. |
+| Status probe | `GET /api/copilot/status`, plus an entry in the CLI-installed probes and `codeman doctor`. |
+| MCP | The entry declares `mcpConfig` (`~/.copilot/mcp-config.json`, dialect `copilot-json`, relocated by `COPILOT_HOME`), so [MCP server sync](./cli-registry.md) treats it as a target and a source. `copilot mcp disable` is honoured (read from `settings.json`, never written). |
+| Plan usage | The header chip's **Copilot** row: the monthly premium-request quota from `GET https://api.github.com/copilot_internal/user`, read at startup and every 10 minutes with Copilot's own sign-in token (`COPILOT_GITHUB_TOKEN`, `GH_TOKEN` or `GITHUB_TOKEN`, else the plain-text token in `<COPILOT_HOME or ~/.copilot>/config.json`; a sign-in kept in the OS keychain shows no row). On by default, like the Codex usage poll: it rides Plan Usage Limits (`showPlanUsageLimits`), and turning that off stops the request. Read-only, redirects refused, the token never logged or stored; any failure leaves the row out. |
+| Docker | The agent image installs `@github/copilot`. No credential directory is seeded (see below). |
+
+### Your own endpoint (BYOK)
+
+With custom model endpoints on, a saved endpoint is offered in the Run menu for Copilot and
+launches straight onto it (no restart; the env is applied before the process starts):
+
+| Codeman field | Variable |
+| --- | --- |
+| base URL (+ `/v1`) | `COPILOT_PROVIDER_BASE_URL` |
+| key | `COPILOT_PROVIDER_API_KEY` |
+| model | `COPILOT_MODEL` |
+
+`COPILOT_PROVIDER_TYPE` is not set: it defaults to `openai`, which is what a Codeman custom
+endpoint is (llama.cpp, vLLM, Ollama). All of these are privileged env keys.
+
+Checked at the CLI level against a local OpenAI-compatible endpoint (1.0.95): it posted to
+`/v1/chat/completions` with the key and the model name, needed no GitHub sign-in, and
+`--resume <id> --model <m>` / `--continue --model <m>` resumed earlier sessions. Tool calls
+through a custom endpoint were not exercised. Only keys are persisted (never values).
+
+## Terminal behavior
+
+Copilot is an alternate-screen TUI with mouse tracking on, so it needed one non-default
+decision, the same one OpenCode needed:
+
+- **Selection.** Left in, xterm reports a plain drag to the TUI instead of selecting, so
+  Auto Copy and copy-on-select silently did nothing (only Shift+drag selected). The entry is
+  `altScreen: 'strip-mux-and-mouse'`: the tracking DECSETs are stripped under tmux, a drag is
+  a local selection, and clicks still reach Copilot through the browser's hand-encoded tap
+  (`cliMouseTracking` is published as the server strips).
+- **Wheel and touch.** Stripping the DECSETs also stops xterm encoding the wheel, so
+  `_shouldForwardWheelToApp` forwards it by hand as SGR reports while Copilot is tracking the
+  mouse; a phone swipe goes through the same gate. Shift+wheel scrolls Codeman's local
+  history. If the tracking flag is stale after a server restart, the gesture falls back to
+  PageUp/PageDown rather than going dead (Copilot pages its own transcript on those keys: three
+  PageUp moved a 140-line answer from lines 109-140 to 010-042).
+- **Keys.** Keystrokes from `tmux send-keys` and `POST /api/sessions/:id/input` reach the
+  composer; Shift+Enter inserts a newline; shell tool calls complete inside tmux
+  (github/copilot-cli#4180 and #4223 report both failing on 1.0.70 to 1.0.74; neither
+  reproduces on 1.0.94).
+- **Scrollbar.** Copilot draws a `┃` gutter at the right edge of every row; the response
+  reader strips it.
+
+## `codeman agent` verbs
+
+The three `CODEMAN_*` variables are exported into every pane, so the
+[session-to-session verbs](../README.md#codeman-agent--session-to-session-verbs-in-every-cli-mode)
+work from inside a Copilot tab and against Copilot workers:
+
+- `spawn` waits for the composer. The ready mark is the footer hint `/ commands · ? help`, **not**
+  `❯`: the folder-trust dialog draws `❯ 1. Yes`, so the glyph would call a worker ready while it
+  is still asking whether to trust the folder. An untrusted folder therefore makes `spawn`
+  warn that the composer was not seen instead of claiming ready.
+- `send --wait` resolves on `idle`. `--until stop` is refused (`400`, "no Claude Code hooks")
+  like every hook-less mode; use `idle`, `exit` or a `--match` marker.
+- `read` returns the last answer. Copilot's output stream is absolute cursor moves rather
+  than lines, so the route reads the pane's **visible screen** (tmux `capture-pane`) and cuts it
+  with a per-CLI pane dialect (`src/web/response-viewer-transcript.ts`): `❯ <prompt>   HH:MM`,
+  `● <answer>` with indented continuation, and the cwd / `Session: N AIC used` row, composer,
+  footer and scrollbar as chrome. Everything before the first prompt (banner, trust dialog) is
+  dropped, so a session that has not been asked anything answers nothing.
+- `interrupt` sends a bare ESC; `rm` refuses itself.
+
+## Docker cases
+
+The agent image installs `@github/copilot`, and a docker case runs Copilot like any mode. **No
+credential directory is seeded**: without a keyring the sign-in token is plain text in
+`config.json`, and `CRED_STORES` (`src/docker-hosts.ts`) deliberately has no `.copilot` row.
+Sign in inside the container (`copilot login`). Setting `COPILOT_GITHUB_TOKEN` for the session does
+not reach it: a docker quick-start refuses `envOverrides`, and Copilot's `dockerExecEnvNames` is
+empty, so a token in the server environment is not forwarded either.
+
+## Remote SSH cases
+
+A remote or Docker pane runs a bare `copilot` (`defaultRemoteCommandForMode`, pinned in
+`test/location-overlay-commands.test.ts`), in Copilot's own Manual Approval mode. The
+`copilotConfig` flags (`--yolo`, `--model`, `--resume`, `--continue`) are a local-session feature
+and are not sent there, so there is nothing for the privileged-param clamp to do. A remote host
+needs its own `copilot` on its own PATH and its own sign-in. This path has unit coverage for the
+built command but was not exercised against a real remote host.
+
+## What Codeman deliberately does NOT wire up
+
+- **No login or token storage.** See Authenticate.
+- **No bypass inferred.** `--yolo` is sent only by the Run button's `allowAll`, never
+  guessed from anything else, and is clamped for non-granted owners.
+- **No `--api-key`-style flag on the command line.** Secrets travel as environment variables
+  through `tmux setenv`.
+- **No Claude-only features.** Auto-resume on a usage limit, the Approvals Inbox, Read My Mind,
+  the Ralph tracker, subagent windows and the bundled agent skill are Claude-shaped.
+
+## Known gaps
+
+- `agent read` does not model tool-call rows: they open with the same `●` bullet and read as
+  part of the answer.
+- `agent read` sees the visible screen, so an answer longer than one screen is its tail.
+- Custom endpoints: tool calls through a BYOK endpoint were not exercised.

+# Media assets: videos and GIFs
+
+Codeman produces a lot of video: README GIFs, website loops, release-note clips, promo videos and their drafts, raw screen captures. This page says where each kind lives and which of them belong in git.
+
+## The rule
+
+**Only media that a public page embeds is pushed to GitHub. Everything else stays on the maintainer's machine, in the local media library.**
+
+| Kind | Where it lives | On GitHub? |
+| --- | --- | --- |
+| GIFs the README, the wiki or a published article embeds | `docs/images/` on `master` | yes |
+| Release-note and media-kit clips | the orphan `design-assets` branch | yes, but never on `master` |
+| getcodeman.com videos and GIFs | `pr/website/assets/` (local, deployed to Cloudflare Pages) | no |
+| Masters, promo videos, drafts, shorts, feature clips, raw captures | `pr/media/` (the local media library) | no |
+| Remotion render inputs for the promo videos | `scripts/remotion/public/` on the unpushed promo branch | no |
+
+`.gitignore` enforces it: `*.mp4`, `*.webm`, `*.mov`, `*.m4v`, `*.mkv`, `*.avi` and `*.gif` are ignored everywhere except `docs/images/*.gif`, plus `scripts/remotion/public/`, whose render inputs the promo branch tracks. A video that really must be committed needs `git add -f`, which makes the exception visible in review.
+
+A GIF that leaves `docs/images/` stays in git history, so removing it does not shrink a clone. The rule keeps new weight out and the tree honest about what is actually used.
+

+
+On 2026-10-13, seven GIFs that no page embedded left `docs/images/` and moved into the library: `codeman-demo.gif`, `codeman-skill-20261010.gif`, `subagent-demo-new.gif`, `subagent-demo-opt.gif`, `tab-alerts-glow-20260815.gif`, `tiles-crt-20261010.gif`, `tiles-crt-stats-20261010.gif`.
+
+### Adding or replacing a README GIF
+
+1. Keep the master (the lossless MP4 or the full-size GIF) in `pr/media/clips/<feature>/`, or in the project folder it came from.
+2. Commit only the size the README shows, named `<feature>-<YYYYMMDD>.gif`, and keep it lean: the current ones are 0.8 to 10 MB.
+3. A replaced GIF leaves `docs/images/` in the same commit, unless something outside the repo hotlinks it (see above).
+
+## Website media (getcodeman.com)
+
+The site is built and deployed from `pr/website/` (gitignored) with `pr/deploy-site.sh`. Its `/docs` pages are generated from `docs/wiki/`, and a wiki GIF that has an MP4 cut of the same run on the site is shown there as that video (the README and the GitHub wiki keep the GIF, since GitHub cannot autoplay inline video). Its videos and GIFs sit in `pr/website/assets/` because that directory is what gets uploaded: they are web cuts (1280 to 1600 px wide, high CRF, posters next to them) derived from masters in the library. `pr/site-notes.md` records how each one was cut and from which master. A few superseded files stay deployed on purpose, so links that point at them keep resolving.
+
+## Release notes and the media kit (`design-assets` branch)
+
+GitHub releases and the Announcements discussions embed clips from the orphan `design-assets` branch (`release-1.40/`, `release-1.41/`, `media-kit-2026-10/`). They are referenced by a commit-pinned raw URL, so the branch can change later without breaking old notes, and none of it ever touches `master`.
+
+## The local media library (`pr/media/`)
+
+`pr/` is gitignored, so the library is never pushed. It holds every master, every finished promo cut and every superseded draft in one tree:
+
+```
+pr/media/
+  README.md          curated guide: what each collection is, which cut is current, where it is published
+  INVENTORY.md       generated list of every file (size, length, resolution, fps, date, published-or-not)
+  inventory.mjs      regenerates INVENTORY.md: node pr/media/inventory.mjs
+  videos/<production>/        finished promo videos; superseded renders in drafts/
+  shorts/<episode>/           per-feature cuts of a promo; older sets in drafts/
+  clips/<feature>/            feature loops and GIF masters (README / site / release clips start here)
+  crt-gifs/                   CRT tile-animation loops
+  files-one-click-20261011/   the Files panel loop project (own README)
+  screenshots-hq/             high-res stills and their capture masters
+  raw-captures/               unedited screen recordings, safe to prune
+```
+
+Two working directories keep files the library only archives, because tools read them from fixed paths: `pr/website/assets/` (the deploy upload) and the promo worktree's `scripts/remotion/public/` (Remotion's `staticFile()` inputs). Renders still land in `scripts/remotion/out/` and are filed into `pr/media/videos/<production>/` once checked. A finished render never goes to `tmp/`.

+# Releasing Codeman (the COM procedure)
+
+> Moved from the root `CLAUDE.md`, which keeps a pointer here. What SemVer covers is defined in `docs/versioning-policy.md`. The root file's Session Safety rules (branch check, explicit paths, never `git add -A`) apply to every step.
+
+When user says "COM":
+
+1. **Determine bump type**: `COM` = patch (default), `COM minor` = minor, `COM major` = major
+2. **Create a changeset file** (no interactive prompts). Write a `.md` file in `.changeset/` with a random filename:
+
+   ```bash
+   cat > .changeset/$(openssl rand -hex 4).md << 'CHANGESET'
+   ---
+   "aicodeman": patch
+   ---
+
+   Detailed description of ALL changes since last release (not just the most recent commit — review full git log since last version tag)
+   CHANGESET
+   ```
+
+   Replace `patch` with `minor` or `major` as needed. Include `"xterm-zerolag-input": patch` on a separate line if that package changed too.
+
+3. **Consume the changeset**: `npm run version-packages` (auto-bumps `package.json` files, updates `CHANGELOG.md`, runs `npm install --package-lock-only`, and verifies lockfile sync via `scripts/check-lockfile-sync.mjs` — all in one command; never hand-edit `CHANGELOG.md` or `package-lock.json` versions. It also writes `src/web/public/whats-new.json` (`scripts/generate-whats-new.mjs`): the bold lead-in of each change in the new `CHANGELOG.md` section, which the browser announces once per version in a toast. Commit it with the release; `test/whats-new.test.ts` fails when its version differs from `package.json`, so a hand bump needs `node scripts/generate-whats-new.mjs && npx prettier --write src/web/public/whats-new.json` too. A release whose notes have no bold lead-ins ships an empty list and shows no toast)
+4. **Sync CLAUDE.md version**: Update the `**Version**` line in the root `CLAUDE.md` (under COM Shorthand) to match the new version from `package.json`
+5. **Commit and deploy**: verify the branch first (`git branch --show-current`), then stage EXPLICIT paths — never `git add -A`, which has swept another session's WIP into a release. `git status --short` and account for every line before committing:
+   `git add <paths> && git commit -m "chore: version packages" && git push && npm run build && systemctl --user restart codeman-web`
+6. **Refresh the getcodeman.com version badge**: the landing page's status bar carries the release version (`v<x.y.z> · getcodeman.com · MIT`), so it goes stale on every release if nobody bumps it. The site source and its deploy script are maintained outside this repository, on the maintainer's machine only; follow the local site handbook there, which also covers the numbers strip and `sitemap.xml` refresh that belong in the same pass. Poll production (`curl -s https://getcodeman.com/ | grep v<x.y.z>`) before calling it done, since the edge lags a deploy by up to a minute. Not applicable to contributor clones — skip it and say so.
+7. **Wait for CI**: after `git push`, TWO workflows fire per master push — `CI` and `Release` (the npm publish + GitHub release). List both runs for the pushed commit with `gh run list --commit $(git rev-parse HEAD) --json databaseId,workflowName` and watch EACH with `gh run watch <id> --exit-status`. Confirm both pass before considering the release done (`gh run list -L 1` returns only one of the two).
+
+8. **Publish the new version to the MCP registry**: `codeman mcp` is listed in the official MCP registry as `io.github.Ark0N/codeman`, and the registry does not follow npm, so every release is published there by hand or the listing stays on the old version. `npm run version-packages` has already written the new version into `config/mcp-registry/server.json` (`scripts/sync-plugin.mjs`). Wait until npm serves it (`npm view aicodeman version`; it can lag the green `Release` run by several minutes), because the registry checks that the npm package exists and carries `mcpName: io.github.Ark0N/codeman`. Then run `cd config/mcp-registry && mcp-publisher publish`, preceded by `mcp-publisher login github` when the saved login has expired, signed in as the account that owns the `io.github.Ark0N/` namespace. Use mcp-publisher 1.8.1 or newer (`mcp-publisher --version`), the release binary from https://github.com/modelcontextprotocol/registry/releases: the Snap Store package is stuck at 1.1.0 and rejects the current `$schema` with a false "deprecated schema detected", so never edit `server.json` for that error. Older publishers also save their login as `.mcpregistry_github_token` and `.mcpregistry_registry_token` (live tokens) in the current directory; move those out of the repo, never commit them. Confirm with `curl -s 'https://registry.modelcontextprotocol.io/v0/servers?search=io.github.Ark0N/codeman' | jq -r '.servers[] | "\(.server.version) latest=\(._meta["io.modelcontextprotocol.registry/official"].isLatest)"'`: the new version must be the one with `latest=true`. Maintainer only (it needs that GitHub account); contributor clones skip it and say so.
+
+9. **Announce it in Discussions**: every release gets a post in the [Announcements](https://github.com/Ark0N/Codeman/discussions/categories/announcements) category, shaped like #418 and #302: the short version first (one bold lead-in per theme, features before fixes, what it does for the user rather than how it works), contributor @-mentions inline where their work is described (a mention notifies them, and a contributor reposting is the cheapest reach this project has), a link to the release, and the Thanks names at the end. Casual first-person voice, no em-dashes, humanizer pass when the skill is available. A same-day follow-on patch (1.28.1 after 1.28.0) is folded into the previous post as an edit, never a second thread. Post it with `gh api graphql -F body=@<file> -f title='Codeman <x.y.z>: <hook>' -f repo=R_kgDOQ-SMDg -f cat=DIC_kwDOQ-SMDs4DCHZE -f query='mutation($repo:ID!,$cat:ID!,$title:String!,$body:String!){createDiscussion(input:{repositoryId:$repo,categoryId:$cat,title:$title,body:$body}){discussion{number url}}}'` (the repo's node id and its Announcements category id; `pinDiscussion` does not exist in the API, so pinning stays a click in the UI). This step exists because announcements stopped at 1.18 (#302) while ten releases shipped with nobody notified; #418 is the backfill covering 1.19.0 to 1.28.1, and release notes only count as content once they reach a surface people are subscribed to.
+
+CI runs `npm run check:lockfile` on every push/PR, so lockfile drift fails the build even if the `version-packages` script is bypassed.
+
+## Security notices
+
+A security notice is a sticky warning card about something outside Codeman that its users should act on (the first: OpenCode's Console breach, October 2026). On a browser that gets the release's update toast it appears inside that toast instead, so nobody sees it twice. Notices live in `src/web/public/security-notices.json`, which is maintained BY HAND; never put one in `whats-new.json`, which `npm run version-packages` rewrites. A notice reaches users only with a release, so add it before the COM that should carry it.
+
+**Adding one**: append an entry to `notices`:
+
+```json
+{
+  "id": "opencode-console-breach-2026-10",
+  "severity": "warning",
+  "cli": "opencode",
+  "published": "2026-10-17",
+  "expires": "2026-12-31",
+  "title": "OpenCode Console breach: check your API keys",
+  "message": "A few short plain sentences, about 50 words at most: what happened and what to do.",
+  "link": { "label": "Read OpenCode's notice", "url": "https://..." },
+  "i18n": { "zh-CN": { "title": "...", "message": "...", "label": "..." } }
+}
+```
+
+- `id` is stable and unique, and never reused: a browser that closed a notice remembers its id (`codeman-security-notices-seen` in localStorage), so a reworded notice under the same id is NOT shown again to anyone who closed it. Give a materially new warning a new id.
+- `cli` (optional) is a registry CLI id. The notice is then shown only on a server where that CLI is installed and enabled; without `cli` it is shown to everyone.
+- `published` and `expires` are inclusive `YYYY-MM-DD` days in the viewer's local time. Set `published` a day before the release ships, so the notice is already live in every timezone when it lands (a browser still on the previous day would otherwise take the plain update toast and see the notice later as a separate card). `expires` is what keeps an old notice from alarming a browser that first opens Codeman months later, so always set one.
+- Keep `message` to about 50 words and do not repeat the card's chrome (the "Security notice" eyebrow and the title are already on it): on a phone the card shares the screen with the update toast's text, and a longer one has to be scrolled to reach its buttons. State only what the affected vendor has said.
+- `title` (optional) is the card's bold line; keep it short. `link.url` must be https. `i18n` is optional; a missing string falls back to the English one.
+- Run `npx prettier --write src/web/public/security-notices.json` and `npm test -- test/security-notices.test.ts`, which validates the file (unique ids, real dates, https links, every `cli` a stock registry id, a zh-CN title wherever there is an English one).
+
+**Retiring one**: let it expire, or delete the entry once it has. Removing it early stops it on the next release only; browsers already showing it keep the card until they close it or reload.

+### GitHub Copilot CLI
+
+GitHub's `copilot`, installed with `npm install -g @github/copilot` (CLI management can run
+that for you). Codeman recognises it only when `--version` answers `GitHub Copilot CLI`, and
+`GET /api/copilot/status` reports the path and version that resolved.
+
+**Quota in the plan usage chip.** While Copilot CLI is installed and signed in, the chip gains
+a **Copilot** row with the calendar-month premium-request quota (requests used and the reset in
+the tooltip). This is **on by default**, like the Codex usage poll: every 10 minutes the server
+asks `api.github.com` for the quota with Copilot's own sign-in token (read-only, redirects
+refused, the token never logged or stored). The token is read from `COPILOT_GITHUB_TOKEN`,
+`GH_TOKEN` or `GITHUB_TOKEN`, or from the plain-text `~/.copilot/config.json`, so a sign-in kept
+in the OS keychain (a macOS or desktop Linux keyring) shows no row. Any failure just leaves the row out. Turn off
+**Plan Usage Limits** in App Settings to stop the request.
+
+**Signing in.** Codeman does not log it in: run `copilot` once and use `/login`, or sign in
+inside a Codeman tab. Copilot keeps the token in the OS keychain when there is one; a headless
+server has none, so it offers to save it as **plain text in `~/.copilot/config.json`**, which is
+what a service ends up with. To keep a token out of a file, give the service
+`COPILOT_GITHUB_TOKEN` (Copilot reads it first, then `GH_TOKEN`, `GITHUB_TOKEN`). The token is
+never copied into a [Docker case](Docker-Cases): sign in inside the container.
+
+**Run button and permissions.** Run starts `copilot --yolo` (allow every tool, path and URL),
+the same bypass switch the other agent CLIs get, so an unattended session never stops on an
+approval. A multi-user user without the bypass grant gets a plain `copilot`, which is
+Copilot's own Manual Approval mode. Model, permission mode and the rest are also changeable
+inside its TUI.
+
+**Options and resume.** `--model` is sent only by an API caller that sets `copilotConfig.model`; the Run menu has no Copilot model picker (a saved custom endpoint sets `COPILOT_MODEL` instead). A session from
+Past Sessions continues with `--continue`, which resumes the most recent Copilot conversation
+in that directory. A tab name you set yourself is passed as `--name`, so Copilot's own session
+list reads like that tab (an automatic `w1-myapp` name is not pinned); Copilot refuses `--name`
+together with `--resume`/`--continue`, so a continued session keeps the name it had.
+
+**Your own endpoint.** With [custom model endpoints](Custom-Model-Endpoints) on, a saved
+endpoint appears in the Run menu for Copilot. It is launched with Copilot's BYOK variables
+(`COPILOT_PROVIDER_BASE_URL` with the `/v1` an OpenAI route needs, `COPILOT_PROVIDER_API_KEY`,
+`COPILOT_MODEL`), needs no GitHub sign-in, and applies at launch with no restart.
+
+**Working and idle.** A turn shows `◉ Working` in the footer, which is what Codeman reads;
+a tool waiting for your approval replaces the composer and reads as idle. The model name is
+read from the footer too. Copilot has no hooks, so the `stop` and `blocked` wait signals are
+not available: wait on `idle`, `exit` or an output marker.
+
+**Selecting and scrolling.** Copilot turns mouse tracking on itself. Codeman strips that, so a
+plain drag selects text (and Auto Copy works) and clicks still reach Copilot. The wheel, and a
+swipe on a phone, scroll Copilot's own transcript; Shift+wheel scrolls Codeman's local history.
+
+**MCP servers.** [MCP server sync](Settings-Reference) includes Copilot's
+`~/.copilot/mcp-config.json` (relocated by `COPILOT_HOME`), as a target and a source.
+
+**From another agent.** The `codeman agent` verbs work from inside a Copilot tab and against
+Copilot workers: `spawn` waits for the composer (not the folder-trust dialog), `send --wait`
+resolves on `idle`, and `read` returns the last answer from the pane's visible screen. Tool-call
+rows are not modelled and read as part of the answer, and `--until stop` is refused as for
+every hook-less mode.
+
+**Not available.** Auto-resume on a usage limit, the Approvals Inbox, Read My Mind and the
+Ralph tracker, as for the other non-Claude CLIs.

+# The Codeman Skill
+
+The codeman skill lets the agent inside a Codeman session drive Codeman itself. You ask in
+plain English, and the agent starts worker sessions in any installed CLI, hands each one its
+task, waits for them, reads their answers and cleans up after itself. No curl, no endpoint
+names, no session ids in your prompt.
+
+It is one skill for every agent CLI, in the `SKILL.md` format that Claude Code, Codex,
+Gemini CLI, OpenCode, Grok, OMP and most other agent CLIs read. It lives in the repo at
+[`skills/codeman`](https://github.com/Ark0N/Codeman/tree/master/skills/codeman).
+
+## See it work
+
+Three real runs on a live Codeman: real sessions, real agents, one typed prompt each.
+Nothing on screen is mocked up; the long waits are sped up and labelled as time-lapse.
+
+### Five workers in the tile grid
+
+The lead Claude Code session gets `use codeman to start 5 claude workers, one per TODO item`,
+and five Claude Code workers power on, one per item, with all six agents working at once.
+
+![A real codeman skill run in the tile grid: the lead Claude Code session powers on as the only tile, the prompt use codeman to start 5 claude workers, one per TODO item is typed, then five Claude Code worker sessions power on as new tiles one after another with the CRT animation, and all six agents work at once](https://raw.githubusercontent.com/Ark0N/Codeman/master/docs/images/codeman-skill-grid-20261015.gif)
+
+Sessions an agent starts do not join the grid by themselves. In this recording each worker
+was put on the grid as it started, the way `Ctrl`+click or dragging its tab does it: see
+[Tile Grid](Tile-Grid).
+
+### Eight workers, eight tabs

+worker's tab shows it at work.

+
+## Install it
+
+Pick one route. The skill only acts inside a Codeman session, so a global install is safe.
+
+| How                | Command                                                                         | Scope |
+| ------------------ | ------------------------------------------------------------------------------- | ----- |
+| Skills CLI         | `npx skills add Ark0N/Codeman --skill codeman -g`                               | Global, any skills-aware agent. The way to give it to pi. |
+| Claude Code plugin | `/plugin marketplace add Ark0N/Codeman`, then `/plugin install codeman@codeman` | Global, through Claude Code's plugin manager. `/plugin update codeman` follows releases. |
+| Bundled CLI        | `codeman skill install`                                                         | Global, at `~/.claude/skills/codeman`. |
+| Bundled CLI        | `codeman skill install --case <name> [--mode <mode>]`                           | One case. `--mode codex` (or any other run mode) writes it where that CLI looks for skills. |
+| Web UI             | **App Settings → Agents & CLIs → All agent CLIs → Codeman Agent Skill**         | Injects it into each case when a session is created, where that session's CLI looks: `.claude/skills/` for Claude Code, `.agents/skills/` for Codex, Gemini CLI, OpenCode, Antigravity, Grok, DeepSeek and OMP. Off by default. |
+
+Use the plugin **or** `codeman skill install`, not both: a Claude Code with both lists the
+skill twice (`codeman` and `codeman:codeman`).
+
+The web UI route skips pi, because a project skill makes pi ask to trust the folder at
+startup. A pi or plain shell session uses the [`codeman agent`
+commands](Driving-Codeman-From-An-Agent#the-codeman-agent-commands) instead, which are the
+same verbs as shell commands.
+
+### Remove it
+
+`codeman skill uninstall [--case <name>]` reverses the CLI installs (with `--case`, every
+Codeman-managed copy in that case, whichever CLI's directory it sits in). It never touches a
+`skills/codeman` you wrote yourself.
+
+Turning the web UI setting back off **does not remove copies it already injected**, because
+a sweep at session start would pull the skill out from under other live sessions sharing
+that directory. Remove them per case with `codeman skill uninstall --case <name>`.
+
+## Then just ask
+
+These prompts work as written:
+
+| You say                                                                                   | What happens |

+| "What sessions are running right now?"                                                     | Lists them with name, mode and status. Read-only. |
+| "Use codeman to start 5 claude workers, one per TODO item."                                | One worker per item, each handed its task, answers gathered as they finish. |
+| "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, waits until the worker is ready, sends and waits, reads the answer, deletes the session. |
+| "Have a DeepSeek Harness worker build search and a claude worker build checkout."          | A mixed fleet: one worker per CLI, started in one go. |
+| "Watch session w4 and tell me if it gets stuck on a permission prompt."                    | Blocks on the `blocked` signal and brings the question to **you**. |
+
+Sessions the agent creates are deleted when it is done, so you can watch the tabs appear and
+disappear in the dashboard while it works.
+
+### A run, start to finish
+
+> **You:** spin up 3 shell workers, run lint / typecheck / the frontend syntax check in
+> parallel, and tell me which failed.

+
+The `DONE_<task>_<random>` strings are the
+[split-marker trick](Driving-Codeman-From-An-Agent#the-split-marker-trick): a shell session
+has no "turn finished" signal, so the skill waits for a marker in the output, typed in two
+halves so that only the command's real output ever contains the joined string.
+
+## Which workers it can drive
+
+Any run mode installed on the machine can be a worker. Claude Code and DeepSeek Harness are
+the two with real completion signals (Claude's from its hooks, DeepSeek's from the harness),
+so the skill can wait for "turn finished" and read the answer as clean text. Every other CLI
+and plain shell sessions are synchronized on an output marker instead, which works the same
+from your side. See [Agent CLIs](Agent-CLIs) for the run modes.
+
+With Claude Code workers, where the installed Claude Code supports it, the lead can also
+message a worker directly instead of typing into its terminal.
+
+## What it will and will not do
+
+- **It self-gates.** Outside a Codeman session (`CODEMAN_MUX` unset) it refuses to act and
+  never guesses an API URL, so a global install costs an unrelated agent session nothing.
+- **Unprompted, it may only** start sessions, prompt them, and delete the 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 brings the
+  question to you instead.
+- **Only when you ask, naming the target:** deleting a case (which erases a real directory
+  of your code), bulk kills, respawn, Ralph, cron, the orchestrator, and settings changes.
+
+## When the agent is Codex
+
+Two things to know:
+
+- Codex's default sandbox blocks network access, even to this machine, so the skill needs
+  **Bypass approvals and sandbox** (App Settings, Codex).
+- Codex 0.162 runs its commands in a shared background process, whose Codeman variables can
+  belong to the session that started it.
+
+The skill checks for both and says so instead of acting.

+# Config Backups
+
+Codeman keeps timestamped copies of the files that hold what you have customized, so a bad
+write, a hand edit or a botched restart can be undone. It is on by default, needs no setup,
+and everything about it (where the copies go, how many are kept, how long) is a setting.
+
+## What is backed up
+
+A fixed list of files from the data directory (`~/.codeman/`, or the directory of the
+[instance](Core-Concepts#instances) you run):
+
+| File | What it holds |
+| ---- | ------------- |
+| `settings.json` | Your preferences that sync across devices, including model and CLI settings. |
+| `clis.json` | CLI enable/disable and custom CLI entries. |
+| `custom-model-hosts.json` | Saved custom model endpoints. **Holds API keys.** |
+| `webhook.json` | Webhook notification target. |
+| `intents.json` | Read My Mind per-case profiles. |
+| `linked-cases.json` | Registered cases. |
+| `remote-hosts.json`, `remote-cases.json`, `docker-hosts.json`, `docker-cases.json` | Remote SSH and Docker overlay configuration. |
+| `webviews.json` | Saved dashboard URLs. |
+| `push-keys.json` | Web-push keys (regenerating them drops every device's subscription). |
+| `users.json` | Multi-user accounts. **Holds password hashes.** |
+| `.env` | Credentials the TUI client reads. **Holds a password.** |
+
+Only files that exist are included. This is an allowlist: nothing else in the data
+directory is ever copied.
+
+**Not backed up:** `state.json` (sessions, and also cron jobs and respawn presets: it is rewritten
+with every session event, so it would bury the real changes), logs, `mux-sessions.json`, the hook
+secret, Docker seeds and caches. Back `state.json` up with your normal file backups if you rely on
+cron jobs.
+
+## When a backup is made
+
+- **At startup**, so the state the server found is always on record.
+- **Whenever the content changes.** The files are read and hashed every five minutes; a new
+  backup is written only if the set differs from the latest backup. An idle server writes
+  nothing, and the history is one entry per real change rather than one per timer tick.
+  A field a file rewrites on its own is not a change, and the comparison looks through it (the
+  snapshot still stores the file exactly as written, and a restore puts those fields back as they
+  were): `custom-model-hosts.json` `lastDiscoveredAt` (the model-discovery poll, every five
+  minutes), `users.json` `lastLoginAt`, `settings.json` `lastUsedCase`, `intents.json`
+  `recentPrompts` and `updatedAt` (every captured prompt) and `docker-cases.json`
+  `lastClaudeSessionId` (a Docker case's conversation id after a `/clear`) and `webviews.json`
+  `lastOpenedAt` (opening a web tab). Without that, every
+  tick looked like an edit and 20 copies covered only about 100 minutes. So Compare shows
+  `intents.json` as unchanged when only prompts differ, yet a restore drops the prompts captured
+  since.
+- **On demand**, with **Back up now** (always writes one, even if nothing changed).
+- **Before a restore**, as a `pre-restore` safety copy of the files about to be replaced (unless
+  nothing changed since the newest backup).
+
+## Where they go and what they are called
+
+The default folder is `<data dir>/backups/config` (`~/.codeman/backups/config`). You can point
+it anywhere with an absolute path (a leading `~` is expanded). A path that is not absolute, or
+that is the data directory itself, falls back to the default.
+
+Each backup is one folder named for the moment it was made, in the server's local time:
+
+```
+~/.codeman/backups/config/
+  cfg-20261011-120305/
+    manifest.json        id, createdAt (epoch ms), reason, appVersion, hash, origin,
+                         keepCount and keepDays in force, SHA-256 + size per file
+    settings.json        the original file names, unchanged
+    clis.json
+    custom-model-hosts.json
+    ...
+  cfg-20261011-123012/
+  cfg-20261011-123012-2/   a second backup in the same second gets -2, -3, ...
+```
+
+| Part | Meaning |
+| ---- | ------- |
+| `cfg-YYYYMMDD-HHMMSS` | Date and time (server local time) the backup was made. A collision in the same second gets `-2`, `-3`, … |
+| `manifest.json` | The record of the backup: `reason`, `appVersion`, the change-check `hash`, the `origin` id, the retention in force (`keepCount`, `keepDays`), and a SHA-256 and size for every file. |
+| `reason` | `startup`, `auto` (a change was detected), `manual` (Back up now) or `pre-restore`. It is in the manifest and the Settings list, not in the folder name. |
+| `.tmp-…` | A backup being written. It is renamed into place when complete and is never listed. |
+
+A folder counts as a backup only if its name matches that pattern **and** it has a valid
+`manifest.json`. That is what makes it safe to point the folder at a directory that also holds
+other things.
+
+## Retention
+
+Two limits, applied after every backup:
+
+| Setting | Range | Default | Meaning |
+| ------- | ----- | ------- | ------- |
+| **Keep this many backups** (`configBackupKeepCount`) | 2 – 500 | 20 | Keep the newest N; older ones are removed. (1 is not offered: every change would delete the state before it.) |
+| **Delete backups older than (days)** (`configBackupKeepDays`) | 0 – 3650 | 30 | Also remove a backup once it has been replaced for longer than this. `0` means no age limit. |
+
+Both apply together. Four guarantees:
+
+- **The newest backup is never removed**, whatever the numbers say, so there is always one to
+  go back to.
+- **Only folders Codeman made are ever removed**, never anything else that happens to live in a
+  custom folder.
+- **Age counts from when a backup was replaced**, not from when it was made. Backups are made on
+  change, so a config that stays the same for months has one backup whose own date keeps
+  ageing; it is the copy you need the day something goes wrong, so it stays until a newer one
+  has existed for longer than the limit.
+- Because backups are made on change, 20 backups reach back across 20 *changes*, however long
+  that took, not 20 timer ticks.
+
+## Settings → System → Config backups
+
+| Control | Setting | Default |
+| ------- | ------- | ------- |
+| Back up my configuration | `configBackupEnabled` | On (absent means on) |
+| Backup folder | `configBackupDir` | empty = `<data dir>/backups/config` |
+| Keep this many backups | `configBackupKeepCount` | 20 |

+
+The settings are saved server-side and read fresh, so a change applies on the next pass. The
+list and **Back up now** use the **saved** folder and retention: apply your edits first.
+
+## Restoring
+
+From the list, press **Restore** on a backup and confirm. Codeman then:
+
+1. **Verifies** every file in the backup against the SHA-256 in its manifest. If any file is
+   missing or does not match, nothing is changed and you get an error. It also refuses a backup
+   folder or file that is a symlink or that group or others can read or write (Codeman never
+   makes one like that, and writing it back as `0600` would turn it into trusted config). The
+   permission test is skipped when the backup folder's filesystem does not keep file modes
+   (FAT/exFAT drives, SMB shares, WSL's `/mnt/d` without the `metadata` option report the same
+   mode for every file, so it would refuse every backup there). The symlink test is not. Compare
+   applies the same checks to the backups it reads.
+2. **Takes a `pre-restore` backup** of the files about to be replaced, so a restore can itself
+   be undone. When nothing changed since the newest backup (the same comparison an automatic
+   backup makes), no copy is made and the response names that backup instead (`safetySnapshot`).
+3. **Replaces each file atomically** (written beside it, then renamed) with mode `0600`.
+
+Only the tracked names are ever written, whatever a manifest lists.
+
+If a file cannot be written (a full disk, a folder where the file should be), the restore still
+writes the others and then reports an error that names the files it restored, the ones it could
+not write, and the backup that holds the files as they were before. The restored files are in
+effect as after a full restore (Settings re-reads `settings.json` into the form), so fix the cause
+and restore again, or restore that backup to go back.
+
+Restoring `settings.json` keeps the four backup settings (on or off, folder, how many, how many
+days) at their current values, so a restore from before a folder change does not point the list
+at the old folder and hide the `pre-restore` copy it just made. The exception is the two
+retention values: where the live `settings.json` lacks one (a reset file), the restore keeps the
+backup's own, key by key, so the next pass does not fall back to 20 copies and 30 days. The
+`pre-restore` copy records the retention in force too.
+
+Settings are re-read on the next request, so reload the page. `.env` and `push-keys.json` are
+read once per process: **restart Codeman** for those to take effect (the response lists which).
+`clis.json` is reloaded by the restore itself and `users.json` is re-read within a second. Restoring `settings.json` also does not re-run the switches
+that saving in Settings applies at once (file watchers and the like), so those apply after a
+restart, and `settings.json` is listed with the restart-required files. A restore does not touch
+running sessions.
+
+When the backup folder is shared (a synced folder used by two machines, or prod and a beta),
+each snapshot records a random id that the instance made once and keeps in its data directory
+(`config-backup-id`; not the hostname, which a Docker container changes on every recreate). Every
+instance only snapshots, lists, prunes, compares and restores its own. Deleting that file makes
+the instance a new owner, and its earlier snapshots stop being listed (they stay on disk). The
+same happens after a reinstall of the data directory. To see them again, copy the `origin` value
+from any of their `manifest.json` files into `<data dir>/config-backup-id`.
+
+You can also restore by hand: the files in a backup folder are the originals, so copying one back
+over the file in the data directory is equivalent (stop Codeman first if you are replacing
+`clis.json` or `users.json`).
+
+## Comparing backups
+
+Before you restore, or to find out what changed and when, use **Compare** in the list:
+
+- **Compare with current** on a backup shows what differs between that backup and the config
+  running now. A restore puts back the files the backup holds; files created since are left as
+  they are, and the restore response names them (`untouched`).
+- **Changes in this backup** shows what differs between the backup before it and this one.
+- The **Compare … with … Show changes** pickers compare any two backups, or a backup with the
+  current config.
+
+Each file that differs is listed with its changed keys (`theme.mode`, `tags[1]`, a variable name
+in `.env`) as before → after, plus files that appeared or vanished between the two states. Files
+that are the same are listed on one line. A file that is not JSON shows only that it differs, and
+a file with more than 200 changes is cut short, so use the files themselves for a full diff. The
+self-rewritten fields listed under "When a backup is made" are not counted as changes.
+
+**Credential values are never shown.** `.env`, `users.json`, `push-keys.json`, `webhook.json` (the
+URL is a bearer secret) and `intents.json` (captured prompts) list only the names that changed, and in every other file a key that looks like a token, secret, password,
+credential or key is shown as "changed" without its value. URL values lose any `user:password@`,
+query and fragment.
+
+## Security
+
+- Some tracked files carry credentials (`.env`, `users.json`, `custom-model-hosts.json`,
+  `push-keys.json`, `webhook.json`). Each backup folder is mode `0700` and its files `0600`, so the default
+  location exposes nothing the data directory does not already.
+- **A custom folder is your decision.** Putting it on a shared drive, a synced folder or a
+  network share copies those credentials there, with whatever permissions that location has.
+  Choose a private location, or turn the feature off if you cannot.
+- **Retention survives a bad `settings.json`.** If it does not parse, a pass still takes its
+  snapshot but deletes nothing. If a retention setting is missing (a reset file), the pass
+  prunes with the retention the newest backup that recorded one holds, not the 20 copies and 30
+  days defaults, and Settings shows those values. Saving sends a retention value only if it was
+  saved before or you edited it there, so saving other settings (or re-entering a custom folder
+  after a reset) does not write the displayed 20 and 30 over it; the first pass in the re-entered
+  folder finds the retention its own backups recorded. While `settings.json` does not
+  parse, a pass reads it as empty, so its snapshot goes to the default folder even if a custom
+  folder is set or backups are switched off; nothing is widened (same modes, inside the data
+  directory).
+- **Anyone who can write to a custom backup folder can plant a backup that Restore applies.**
+  Restore refuses symlinks and files others can write, but a file of your own user's making
+  passes, so keep the folder private.
+- In [multi-user mode](Multi-User-Mode) all of it is admin only: the list, Back up now,
+  Restore and Compare, and each restore is written to the admin audit log
+  (`config_backup_restore`).
+- Listing returns file names and sizes, never contents. A comparison returns changed values but
+  never a credential's (see [Comparing backups](#comparing-backups)).

+## Troubleshooting
+
+- **The list is empty.** None of the tracked files existed yet, or backups are turned off. Press
+  **Back up now**.
+- **"Backups are not available here".** You are not an admin in multi-user mode.
+- **No new backup after I changed a setting.** Changes are picked up within five minutes; **Back up
+  now** takes one immediately.
+- **A restore said a file does not match its checksum.** The backup was altered or damaged on
+  disk. Nothing was changed; restore an earlier one.
+- **The backups folder is growing.** Lower **Keep this many backups**. Each backup is a few
+  kilobytes, but `custom-model-hosts.json` and `intents.json` can be larger.
+- **I want my own off-machine copy.** Point the folder at a location your backup tool already

+**A context that is big enough overall can still be too small once it is split across
+slots.** `llama-server` runs several parallel slots by default (four on the build this was measured on) and,
+unless you say otherwise, they all share one pool of context. Claude Code sends more than one

+`Context size has been exceeded`, even though any single request would have been fine.
+Discovery therefore also records how many slots each loaded model has. It reads an explicit
+`--parallel` or `-np` from the launch command, and otherwise asks the server for
+`total_slots`, because a server started without the flag chooses the number itself. When the
+context divided by the slot count drops below what Claude Code needs, picking that model shows

+```yaml
+cmd: >-
+  llama-server -m /models/your-model.gguf --parallel 1 ...
+```
+
+With one slot the active conversation gets the whole context, requests from parallel
+subagents queue behind it instead of failing, and Claude Code's repeated prompt prefix stays
+in the cache instead of being processed again in a different slot each time. The alternative

+# Git Worktrees
+
+Sessions in one case share its folder. That is fine for one agent, but three agents in the
+same checkout edit the same files, overwrite each other's builds, and commit each other's
+half-finished work. A **git worktree** gives each of them a checkout of its own: same
+repository, same history, a separate folder on a separate branch.
+
+Codeman creates worktrees for a case whose folder is a git repository, starts sessions in
+them, and removes them again when the work is done.
+
+## Where they live
+
+`<case>/.claude/worktrees/<name>`, on a new branch `worktree-<name>`. That is exactly where
+Claude Code's own `claude --worktree <name>` puts them, so a worktree made in Codeman is one
+Claude Code recognizes, and the other way round. Codeman's Recent Sessions and Session Manager
+lists mark a session that runs in one with a `⑂ <name>` pill.
+
+The main checkout does not show the worktrees as untracked: Codeman adds `/.claude/worktrees/`
+(and `/.claude/settings.local.json`, the hooks file it writes for every Claude session, plus the
+`codeman` folder it writes when **Codeman Agent Skill** is on) to the repository's local
+`.git/info/exclude` when git does not ignore them already. Without that, those files would make
+every worktree look modified and git would refuse to remove it. Your tracked `.gitignore` is
+never touched.
+
+## Creating one and starting a session in it
+
+1. Pick the case in the toolbar's case picker.
+2. Open the picker again and choose **Git worktrees…** (on a phone: the case sheet's
+   **Worktrees** button).
+3. Under **New worktree**, type a name (letters, digits, `.`, `_`, `-`, up to 64 characters).
+4. Pick the CLI under **Start sessions with** (Claude Code, Codex, a shell, any installed run
+   mode).
+5. **Create & start session**.
+
+The worktree is created from the case's current commit, and the session opens in it as a tab
+named `w1-<name>`. Under **Branch and start point** you can name the branch yourself or start
+from another branch, tag or commit. An existing branch is never reused or reset: pick another
+name.
+
+**Open** on a worktree's row starts another session in it, with the CLI chosen above.
+
+## Removing one
+
+Two ways, and both use `git worktree remove` **without** `--force`:
+
+- **Remove…** on the worktree's row in the dialog.
+- Closing a session that runs in a worktree: the Close Session dialog offers **Kill & remove
+  worktree**, which kills the session and then removes its worktree.
+
+git refuses to remove a worktree that still holds uncommitted or untracked files, and Codeman
+shows that refusal as git worded it and leaves everything in place. Commit, stash or delete the
+work first, then remove again. A worktree a live session still runs in is refused too.
+
+**Also delete its branch** deletes the branch with `git branch -d`, which keeps a branch whose
+commits are not merged yet. The worktree is still removed, and the message says the branch was
+kept.
+
+If a worktree's folder was deleted by hand, its row says **missing** and offers only
+**Remove…**: that clears the record git keeps of it, so the name can be used for a new worktree.
+
+## What is not supported
+
+- **Docker cases and remote (SSH) cases.** A container can write to its workspace, and creating
+  a worktree runs the repository's hooks and checkout filters on the Codeman machine, so git is
+  never run there. A remote case's repository is on another machine. For the same reason a
+  worktree that a Docker case uses as its workspace (or that holds one) is never removed from
+  here: remove the Docker case first.
+- A case folder that is not the top of a repository (a subfolder of one), a bare repository, or
+  an empty repository with no commit yet.
+- Worktrees outside `.claude/worktrees/` (made by hand with `git worktree add`) are listed, but
+  Codeman neither starts sessions in them from the dialog nor removes them.
+
+The HTTP endpoints are in the [HTTP API](HTTP-API) reference (`/api/cases/:name/worktrees`).

@@ -107,10 +109,19 @@ Claude Code bills a turn against the cached conversation while that cache is war
 
 Claude Code 2.1.251 and newer reports the cache state on the statusline after every response, and Codeman's statusline exporter keeps it per session. The row shows **Warm until HH:MM** with the lifetime and the tokens that would be re-cached if it went cold, or **Cold** with the size of the re-cache the next turn pays. When Claude reports them it also shows the session's cache hit rate and the cause of the last cache miss (for example `ttl_expired_1h` or `tools_changed`), so a surprise miss has a reason next to it. If the conversation is compacted while it stays warm (Claude Code now does this on its own on large idle sessions, a manual `/compact` does it too, and so does a clearing of old tool results), the row notes **Context compacted at HH:MM** until the next turn: Claude Code reports no re-cache size until then. None of this raises an alert. The row refreshes live and flips to cold on its own when the lifetime passes, and the last state is kept across a Codeman restart so it is not blank until the session's next turn. Sessions without a statusline of their own also get a short `cache:until HH:MM` or `cache:cold` group in the terminal footer. The readout rides the plan usage chip's telemetry collection, which is on by default on desktop.
 
+**Keep the cache warm while idle** is the switch under the readout. With it on, Codeman sends a one-line keep-alive turn (`Codeman cache keep-alive: no action needed, reply with just "ok".`) about five minutes before the cache would expire. Claude answers `ok`, the request refreshes the cache for another hour, and your next real prompt reads the conversation from cache instead of re-processing it. Measured on sessions of about 110k tokens, the keep-alive cost a cache read plus a one-word reply, a small fraction of the re-write it prevented.
+
+It only fires when there is nothing else going on: the session is idle with an empty prompt (Claude Code's greyed-out prompt suggestion counts as empty), no permission or question dialog is open, nobody has typed in the last few minutes, no respawn loop, Ralph loop or waiting agent is driving the session, and the session is not paused on a usage limit. If any of those hold it waits a minute and looks again, and gives up a minute before the expiry rather than race it; a keep-alive that could not be sent is retried the same way. It also stops by itself a few hours after your last prompt (**Keep warm for at most**, under App Settings → System → Automation, default 2 hours), because the saving is concentrated in gaps of one to four hours and an overnight run of hourly keep-alives would cost more than the single cold turn in the morning. It stands down for the rest of a gap once the context has been compacted. The readout's Status line gains a `Keep-alive:` line that says what it is doing: the next keep-alive and when the window closes, waiting and why, sent at a time with a count, or stopped and why. A session started without the cache readout (Plan Usage off at launch, a workspace with its own statusLine, a remote or Docker session) cannot be kept warm: the switch is greyed out and cannot be switched on (one that is already on can still be switched off), and the Status line says why.
+
+Recent Claude Code builds can compact a large idle session on their own shortly before the cache expires, which would leave only a summary to keep warm. So a session **started** with keep-warm on also launches with Claude Code's idle compaction switched off (Claude Code 2.1.290 or newer); Codeman then owns the idle policy for it. A session you switch on after it started is still kept warm, but Claude Code may compact it first until its next launch, and the Status line says so; one you switch off keeps Claude Code's idle compaction off until its next launch, and the Status line says that too. Sessions with keep-warm off launch exactly as before.
+
+**Keep prompt caches warm** in the same Automation group is the default for sessions that have not chosen on their Respawn tab; the per-session switch always wins. A session another agent started (a worker) does not follow the default: most workers are never prompted again once they report done, so turn it on for one by hand if you will come back to it. The keep-alive turn is Codeman's, not yours: it does not restart the **Keep warm for at most** window, does not rename a tab, Read My Mind ignores it, and the response it ends with raises no alert, toast, push or webhook, nor a row in the Away digest or the session's Summary. It never clears an alert that was already waiting for you. It is refused on the five-minute cache lifetime, which is what an API key, a cloud provider or extra-usage credits get; a session on an API key can ask Claude Code for the hour with `CLAUDE_CODE_PROMPT_CACHE_TTL=1h` in its environment overrides.

+Uploads land in `.codeman-uploads/` inside the case, next to the code the agent is working
+on, because that is the one path a local agent and a Docker case (whose workspace is mounted
+at the same absolute path) both see the same way. The first upload writes a `.gitignore` of `*` into `.codeman-uploads/`, so the
+directory ignores itself and your repository never picks the files up, while your own ignore file is
+left alone; a `.gitignore` you already had there is never overwritten. Files older than seven
+days are swept hourly, and the directory goes when the last session of the case is closed (a
+session that is only detached keeps it). Earlier releases wrote to `.claude-images/`; that
+directory is still swept and cleaned up the same way for one release so a case in use before
+the move is not left with stray files.

+ * - The newest snapshot is never pruned, whatever the retention numbers say.
+ * - A snapshot is built in a temp folder and renamed into place, so a crash leaves no half snapshot.

+ * on one repository each get their own working tree instead of sharing the case folder (sessions
+ * in one case share its folder, and two agents editing, building and committing in one checkout
+ * step on each other). Routes: `src/web/routes/worktree-routes.ts`; a session starts in one
+ * through the existing create paths (`POST /api/quick-start` with `worktree`, or
+ * `POST /api/sessions` with the worktree as `workingDir`).
+ *
+ * WHERE. `<repo>/.claude/worktrees/<name>` on a new branch `worktree-<name>` is Claude Code's own
+ * `--worktree` layout (measured in Claude Code 2.1.296: path `<repo>/.claude/worktrees/<name>`,
+ * branch `worktree-<name>`, names of letters, digits, `.`, `_`, `-`, at most 64 characters), and
+ * Codeman already recognizes it (the worktree pill, `CLAUDE_WORKTREE_PATH` in session-routes.ts).
+ * Names here are a strict subset of Claude's (one segment, starting with a letter or digit), so a
+ * worktree made here is one `claude --worktree <name>` would also find. The main checkout must not
+ * show the worktrees as untracked, so `/.claude/worktrees/` is appended to the repository's LOCAL
+ * `info/exclude` (in the real common git dir, never a tracked `.gitignore`) when git does not
+ * already ignore it. `/.claude/settings.local.json` gets the same treatment: Codeman installs its
+ * hooks there for every claude session, and an untracked copy in a worktree makes
+ * `git worktree remove` refuse forever (Claude Code itself ignores that file through the global
+ * excludes file, which is not guaranteed to be set up on a given machine). The copy of Codeman's
+ * agent skill (`<skills dir>/codeman/`, injected while `agentSkillEnabled` is on) is excluded for
+ * the same reason, for every skills folder the registry names (`WorktreeOptions.agentSkillDirs`).
+ *
+ * Split like the other git modules: a PURE half (name and branch validation, `worktree list`
+ * parsing, exclude text, the managed-path rule) unit-tested without git, and an IO half that
+ * spawns git through an injectable runner.
+ *
+ * Rules the code keeps and the tests pin:
+ *   - git is spawned with an argv array, never a shell, with `--` before every path operand, the
+ *     non-interactive environment of `gitNonInteractiveEnv()`, a timeout that kills the whole
+ *     process group, and capped output. Read-only calls add `--no-optional-locks`.
+ *   - Names and branches are validated BEFORE they reach git (charset, length, then
+ *     `git check-ref-format --branch`, whose answer must equal the input: `@{-1}` style shorthands
+ *     are refused up front, since `--branch` would expand them).
+ *   - Only `<repo>/.claude/worktrees/<valid-name>` is ever created or removed. Every component of
+ *     that path is `lstat`ed (a symlinked `.claude` or `worktrees` directory, or a symlink at the
+ *     worktree itself, is refused) and its real path must be exactly the expected one, so a
+ *     repository cannot redirect a create or a remove outside itself. What is left is a same-user
+ *     race (an agent swapping a directory between the check and git), which is accepted: that
+ *     agent already runs code as this user.
+ *   - Removal is `git worktree remove` WITHOUT `--force` (git refuses a tree with modified or
+ *     untracked files, and that refusal is the answer), refused while a live session runs inside
+ *     the worktree, and the optional branch delete is `git branch -d` (never `-D`, so an unmerged
+ *     branch survives).
+ *   - git never runs for a case at or inside a Docker case workspace (or whose common git dir is
+ *     there): a container could plant a checkout filter or a hook, and `git worktree add` runs the
+ *     repository's post-checkout hook and filters on the HOST. On a local case that is acceptable,
+ *     since the user's agent runs code there anyway. A managed worktree that is, sits inside, or
+ *     holds a Docker case workspace is never removed either: `git worktree remove` runs a status
+ *     inside the tree, then deletes it under the container.
+ *   - A repository that merely encloses the case and is the home folder or above (a dotfiles repo
+ *     in `$HOME`) is not the case's repository, and a case folder below a repository's top level
