+
+### Minor Changes
+
+- 6f88e40: ### Thanks
+  - @opticon454 for four PRs in one night: the Git status indicator with its panel of uncommitted and unpushed work and per-file diffs (#537), `codeman doctor` in Settings (#536), creating a case in a custom folder (#535) and the detailed-rail rename clamp fix (#534). Both review rounds came back within half an hour with every item addressed.
+  - @aakhter for making the grouped vertical rail editable end to end (#525), the inline rename write queue and the long-prefix editor layout (#526), and bounded path probes so an unreachable network mount can no longer freeze the server (#516). Every round came back with tests that replay the exact sequences from the review, and the review nits were already fixed before landing.
+
+  **Edit tab groups in the vertical rail (#525).** The grouped rail is now editable from the browser: create, rename, reorder and delete groups, and move tabs between groups or back to Ungrouped, from the row menu, a group menu (Shift+F10, ContextMenu, right-click, or the header glyph, which stays visible on touch screens; F2 renames inline) or a mouse/pen drag. A flat rail offers "Move to new group" to make the first one. Every edit is a named operation saved through the existing `PUT /api/tab-layout`, one write in flight at a time; a version conflict replays the pending operations onto the server's layout and retries, so a concurrent edit from another device survives, and unsaved edits survive a reload. A drag released outside the rail leaves nothing behind, and committing a group rename by clicking elsewhere leaves focus where you clicked. No server changes.
+
+  **Inline rename that keeps up (#526).** Inline renames go through a per-session queue: one PUT at a time in the order they were made, the confirmed name applied even if the editor was reopened or cancelled meanwhile, an editor reopened over a rename in flight starts from that name, and a failed rename always shows its toast. A long `w<n>-<case>` prefix no longer pushes the editor out of its row in the rail or the sidebar, and the detailed rail no longer keeps its 3-line clamp around the editor (#534 found and fixed the same clamp independently).
+
+  **Git status in the bottom bar (#537).** Turn on Settings → Header & Panels → Bottom bar → "Git status" (per-device, off by default) and a small indicator shows the active session's repository at a glance (`● 3` uncommitted files, `↑ 2` commits not pushed, `✓` when everything is committed and pushed). Click it for a draggable window listing the uncommitted files (staged, not staged, untracked, conflicts; click one for its diff; grouped under collapsible folders) and the unpushed commits. A folder holding several projects gets a section per repository found up to two levels down, and an unrelated repository above the workspace (a dotfiles repo in your home folder) is ignored. Read-only and offline: Codeman never fetches or changes the repository, and git never runs on a repository a Docker case can write to. Not shown for Docker or remote sessions. New `GET /api/sessions/:id/git-status` and `GET /api/sessions/:id/git-diff`.
+
+  **Diagnostics in Settings (#536).** Settings → System → Diagnostics runs `codeman doctor` on the server (`GET /api/doctor`) and lists which agent CLIs, tmux, Node and the optional office tools are installed, with versions, paths and install hints. The probe runs in a child process, so a slow `--version` cannot freeze the server, and both the panel and the terminal `codeman doctor` now also look in each CLI's usual install directories, so a CLI installed outside a service's minimal PATH is found. Admin only in multi-user mode.
+
+  **Create a case in a custom folder (#535).** Add Case → Create New has a "Create in a custom folder" option with a Browse button: the case folder is created inside the parent you pick, scaffolded like any other case and listed alongside the rest (deleting it unlinks, never removes files). `POST /api/cases` accepts an optional `path` for the same thing. The folder must not exist or must be empty, and system folders, the home folder, credential folders and the cases directory itself are refused. Nothing is left behind if creation fails part-way. Admin only in multi-user mode.
+
+  **An unreachable mount no longer freezes the server (#516).** A linked case can live on a network mount, and when that mount goes away a hard mount makes `stat()` wait indefinitely; the synchronous probes in the case routes, the workspace hook and statusLine helpers and session creation used to freeze the whole server with it. Those probes now go through one bounded, tri-state probe (present, absent, or unknown when nothing answers in time): a stalled path costs one threadpool worker, paths on the same mount answer "unknown" without a new stat, and unrelated paths keep working. "Unknown" is never treated as "absent": `GET /api/cases/:name` reports an unreachable linked case with `unreachable: true` instead of NOT_FOUND, Run creates a case only on a real NOT_FOUND, and session creation answers OPERATION_FAILED for a folder that did not answer and never scaffolds over it. Tunable with `CODEMAN_PATH_PROBE_TIMEOUT_MS` (default 1500) and `CODEMAN_PATH_PROBE_MAX_STALLED`.
+
+  **Fixes applied while landing.** Tab groups: an edit made while an earlier save was still in flight, and made inapplicable by that save's conflict (its group deleted on another device), is no longer dropped silently but reported like every other dropped edit, and the menus stop offering a new group once the 32-group limit is reached instead of failing with an untranslated error. Rail: a static CI check now pins that no rail or sidebar clamp out-ranks the rename unclamp (the browser test that caught it is outside the gate). Git status: a cached repository list is re-checked against the current Docker workspaces on every poll, a diff larger than 8 MB is cut short instead of failing, a diff click refreshes only that repository, a dotfiles repository above the workspace is identified with one `rev-parse` before any full status (a failing status there no longer hides the repositories below), and "Upstream is gone" now reads "Upstream not on remote", which is also true for a branch that was never pushed. Doctor: candidates are judged like the Run menu's own resolver (a wrong binary on the PATH no longer hides the right one in an install directory, a non-executable file or a relative directory reads as missing), probes are killed with SIGKILL on timeout, a missing optional tool shows ○ instead of ✗, and the contract test no longer runs the machine's installed CLIs. Custom-folder cases: the symlink-resolved target is judged against resolved roots too (home reached through a link, macOS `/private/etc`), a target inside the cases directory is refused, the success toast names the folder the server created, the new labels have zh-CN translations, and the route test can no longer delete a real `~/projects` or the live linked-cases registry when run outside `npm test`.

+## 1.34.0
+
+### Minor Changes
+
+- 6aecc3b: ### Thanks
+  - @opticon454 for four PRs in one batch: webhook notifications (#523), MCP server sync (#521), the Shift+Enter keypress fix (#520) and the newline chord plus Key tester (#522). Every review item was answered in one round, and the merge-order map across all four made landing them together easy.
+  - @aakhter for the grouped vertical rail (#517) and its ARIA tree and full-row activation (#519), which give the owner tab-layout API its first frontend, and for the iOS IME composition preview (#499), carried through three careful review rounds including the overlay rework in the zerolag package.
+  - @irisitymichaelgrundberg for per-session Claude models on `POST /api/sessions` (#514) and Codex reasoning effort per session (#515), both kept registry-driven with no CLI id branching.
+  - @timkjr for keeping Pane B painting during a history pull and its "disconnected" marker last in every interleaving (#524), with an old-versus-new table measured in real Chrome.
+
+  **Webhook notifications (#523).** Settings → Notifications → Webhook posts the same events as Web Push (permission prompts, questions, errors, idle) to ntfy, Slack, Discord or any JSON URL, so a headless server can reach a phone with no browser open. Off by default. The URL is a bearer secret: it lives in its own 0600 file (`~/.codeman/webhook.json`), is never returned by the API, and the routes (`GET`/`PUT /api/webhook`, `POST /api/webhook/test`) are admin only in multi-user mode. Delivery goes through the web-tab egress guard (link-local and cloud-metadata targets refused), does not follow redirects, times out after 5 s, dedupes repeats, and neutralises `@everyone`/Slack control characters in agent-supplied text.
+
+  **MCP server sync (#521).** Opt-in (`mcpSyncEnabled`, synced, off by default; `GET`/`POST /api/mcp-sync` answer 403 until it is on). Settings → Agents & CLIs → MCP servers previews or copies each installed, enabled CLI's MCP servers into the others' own config files (Claude, Gemini, Codex, OpenCode, Antigravity). It only adds missing servers, never edits or removes one, skips servers you switched off, keeps a `.codeman-bak` of every file it changes, re-parses the result before writing, writes through symlinked dotfiles, leaves files that receive env values or headers readable by you only, and reports same-name conflicts instead of overwriting. CLIs with no known MCP config (Pi, Grok, OMP, DeepSeek) are listed as unsupported. Adds the `smol-toml` dependency to read Codex's `config.toml` safely.
+
+  **Claude advisor tool.** Claude Code's experimental advisor (a stronger model the session's main model consults at decision points) can now be set per session: an `advisorModel` field on `POST /api/sessions`, `POST /api/quick-start` and `POST /api/ralph-loop/start` (`fable`, `opus`, `sonnet`, or a full id in those families), and a synced App Settings default under Models → Advisor. It rides the launch's one `--settings` JSON rather than the `--advisor` flag, because the flag exits at launch on any pairing the CLI refuses and would leave a dead pane on every respawn. It is persisted, so respawns and both restore paths keep it, and `/advisor` still switches it in-session. Agents using the codeman skill can give their claude workers one with `CODEMAN_WORKER_ADVISOR=opus`.
+
+  **Per-session Claude model (#514) and Codex reasoning effort (#515).** `POST /api/sessions` takes an optional `model` that launches that one Claude session with `claude --model <id>` and writes nothing to disk (`modelOverride` still writes the case default). It is persisted, so both recovery paths relaunch on it. `codexConfig.reasoningEffort` starts a codex session at a chosen effort (`--config model_reasoning_effort=<level>`), and it survives respawn and resume.
+
+  **Grouped vertical rail (#517, #519).** When the owner has tab groups (`/api/tab-layout`), the vertical rail draws them as collapsible sections, with collapse remembered per device, the active row always visible, and lineage arcs anchored to a collapsed group's header. The grouped rail is an ARIA tree with one tab stop and the standard arrow-key model. With no groups, the rail is unchanged byte for byte. Editing groups from the browser comes in a follow-up.
+
+  **iOS IME composition preview (#499).** On iOS Safari, the text an IME is composing (Japanese, Chinese, Korean, and the predictive composition on English keyboards) is now drawn in the terminal before it commits, inside the local-echo overlay when local echo is on. Inert on every other platform. The `xterm-zerolag-input` package gains `setComposition()`.
+
+  **Key tester and newline chord (#522).** Settings → Terminal & Input has a Key tester that shows the keydown/keypress/keyup events the browser reports, to diagnose a device where a shortcut behaves differently. Keys pressed in it never trigger app shortcuts. Shift+Enter's newline chord is now CLI registry data (`capabilities.newline`, line feed by default); no stock CLI changes.
+
+  **Fixes.** Shift+Enter no longer submits the prompt after inserting the newline: the key handler swallowed only `keydown`, so xterm's `keypress` still sent a bare `\r` (#520). Claude sessions created at the same moment (`spawn_workers`, a multi-tab Run) no longer fall out of tmux onto the direct-PTY fallback: the statusLine exporter's temp file name collided within one millisecond (#531). Pane B of the split view keeps painting during a history pull, and its "disconnected" marker stays the last line however a close, a pull and a refresh interleave (#524).
+
+  **Fixes applied while landing.** Webhooks: the App Settings Save button now saves webhook edits too (a refused URL keeps the dialog open with a warning), Send test saves pending edits first, and a Remove URL button clears a saved URL. MCP sync: a config file that fails to parse is reported by line and column only, never by quoting its content, which can hold API keys; the sync follows `CLAUDE_CONFIG_DIR`, `CODEX_HOME`, `XDG_CONFIG_HOME` and `GEMINI_CLI_HOME` from the server's environment and skips a target it cannot place instead of writing a file the CLI never reads; Preview before saving says to save first; and the MCP group is hidden from non-admins in multi-user mode. Grouped rail: a collapsed group's header shows the red or yellow ring of a hidden row that needs you; layout reads rebuild the rail only when something it draws changed, and failed reads back off (5, 10, 20, 40 s) instead of retrying every 5 s forever; a corrupted collapse preference resets instead of disabling collapse; Ctrl+Shift+{ / } only moves a tab within its own group; tapping a group header or row no longer dismisses the phone keyboard; keys pressed on a row's own buttons no longer move tree focus; and screen-reader positions stay correct after a re-sort. Sessions: `model` on `POST /api/sessions` refuses a value starting with a dash, and `model` or `advisorModel` together with `attachRemoteSession` is now a 400 instead of being ignored; non-Claude sessions no longer report or persist Claude's default model. Split view: a refresh queued behind a history pull no longer leaves a second, stale "disconnected" marker above its replay. iOS IME: a composition on an empty prompt now follows the prompt when output or a resize moves it, and the `xterm-zerolag-input` README documents `setComposition()`. The Shift+Enter and Key tester browser tests now drive the shipped handlers instead of copies.
+
+## 1.33.3
+
+### Patch Changes
+
+- f776ad8: ### Thanks
+  - @JDProfresh for rendering Markdown in the File Viewer (#503) through the chat's existing markdown pipeline and sanitizer rather than a second one, plus the Lines and Wrap toggles and the sanitizer fix that stops a document from clobbering `document.app`.
+  - @timkjr for bringing the Shell scroll-to-top history pull to the split view's second pane (#506), following #494's rules down to the back-off, with tests that fail on the code before each fix.
+  - @irisitymichaelgrundberg for the `#session=<id>` dashboard link (#507), so a page that keeps one Codeman window open can switch it between sessions without reloading it.
+  - @dignfei for handing focus back when the Command Palette or the Session Manager closes (#509), and for the six-overlay measurement that showed exactly which two were broken.
+
+  **Markdown files render in the File Viewer (#503).** Opening a `.md` or `.markdown` file now shows it as a document: headings, tables, code blocks with the same copy buttons as the chat, images relative to the file, and links to other documents that open inside the viewer. An `MD` pill switches back to the source, and Edit works from either view. Plain text gets a `Lines` gutter (never part of a copy) and a `Wrap` toggle, all three remembered per device. `.avif` images preview inline, and printed `.avif`/`.ico` paths open the viewer instead of the tail view. An in-workspace file path clicked in the terminal still opens the live tail view.
+
+  **Link a dashboard window to a session (#507).** An outside page, such as a task board, that keeps one Codeman window open can now switch it to a session by pointing it at `/#session=<id>`. Only the fragment changes, so the page stays loaded and the switch is an ordinary tab selection. A link to a session the dashboard does not list yet waits up to 30 seconds for it to appear and then shows "Session not found"; picking another tab, going Home or opening a web tab cancels the wait. Following a link does not count as looking at the session, so its idle alert stays armed. The fragment is documented in `docs/extending-codeman.md` and is now a stable surface under `docs/versioning-policy.md`.
+
+  **Escape no longer strands the keyboard (#509).** Closing the Command Palette or the Session Manager now hands focus back to whatever held it before they opened, usually the terminal, so you can keep typing without clicking first. An Escape pressed while neither is open changes nothing.
+
+  **Split view: a Shell Pane B scrolls back into tmux history (#506).** Wheel up at the top of a Shell session in the split view's second pane now pulls the most recent 1 MiB of its tmux history and keeps your place, the same as the primary pane since 1.33.2.
+
+  **Fixes applied while landing.** Markdown opened from an attachment card no longer resolves relative images and links against the workspace root, where they could show a missing image or open a different file of the same name; they render as their alt text and link text instead. Rendered files no longer turn every source line break into a hard break the way chat messages do, so a README wrapped at 80 columns reads as flowing paragraphs. Absolute-path links inside a rendered document open in that document's session. A disconnected Pane B keeps its "disconnected" marker as the last line even when the socket closes in the middle of a history pull. Closing the Session Manager through a row's "Switch to session" or "Open folder" no longer pulls focus back from the terminal to the header button.
+
+## 1.33.2
+
+### Patch Changes
+
+- e439cf0: ### Thanks
+  - @aakhter for keeping web-tab events private to their owner in multi-user mode (#501), with end-to-end isolation tests that fail without the fix, and for the browser-test exclusion check and pre-push hook (#500), including the hooks-dir resolution that never writes outside the repo's own `.git/hooks`.
+  - @opticon454 for keeping CLIs installed from Settings across Docker container updates (#490) and for the static Git identity for the Docker images (#492).
+  - @timkjr for letting a Shell pane's scroll-to-top reach tmux history (#494), with tests that fail on the commit before each fix.
+  - @JDProfresh for tracking down why wheel and touch scrolling did nothing in Claude's default inline view (#498), with the tmux measurements that proved it.
+  - @irisitymichaelgrundberg for the follow-up that makes an agent waiting on artifact comments raise its alert again (#491).
+
+  **A tab stays busy while Claude waits for its own workers.** When Claude hands work to an ultracode workflow or background agents, it ends its turn with `✻ Waiting for 1 dynamic workflow to finish` and resumes by itself when they report back. The idle probe used to call that session idle for the whole wait, and at phone width nothing on screen changes for minutes. A new optional registry field, `capabilities.workDetect.awaitingLine`, names that closing row, and only the newest column-0 row directly above the composer counts, so the session goes idle normally once the follow-up turn ends.
+
+  **Prompts sent through the API are no longer left unsent.** A prompt posted to `POST /api/sessions/:id/input` without `useMux` was written into the pane in one piece, and Claude Code (measured on 2.1.283) takes a burst of about a hundred characters or more as a paste, so the trailing `\r` became a newline and the prompt sat on the composer while the route answered 200. Short prompts went through, which is why it looked random; Codex and OpenCode showed the same thing. A plain prompt (printable text plus exactly one trailing `\r`) now goes through tmux: the text is typed, Enter is pressed as its own key, and the server presses it again while the prompt is still on the composer. Raw frames (escape sequences, a bracketed paste, a line feed, a bare `\r`) and an explicit `"useMux": false` keep the direct write. The same fix reaches cron jobs in "Paste (direct)" input mode, which reported `prompt_sent` for a prompt that never left the composer: the text is written raw, Enter follows as its own write 300 ms later, and the session presses it again while the prompt is still unsent. A cron run with no session to write to now fails instead of reporting the prompt as sent.
+
+  **Scrolling works again in Claude's default inline view (#498).** Wheel and touch gestures were forwarded to every Claude 2.1.187+ session as mouse reports, but only Claude's fullscreen renderer (`CLAUDE_CODE_NO_FLICKER=1`, or `"tui": "fullscreen"` in `~/.claude/settings.json`) listens for them, so in the default view scrolling did nothing. Codeman now forwards them only while Claude has mouse tracking switched on, and otherwise scrolls the terminal's own scrollback.
+
+  **Shell panes scroll back into tmux history (#494).** Scrolling to the top of a Shell pane now pulls the most recent 1 MiB of its tmux history, so output that arrived in a burst is reachable without pressing **Load full history**, which still loads the rest.
+
+  **An agent waiting on artifact comments alerts again (#491).** A session whose agent published an artifact and is waiting for somebody to comment on it now raises the normal idle alert and lands in NEEDS YOU, instead of being treated as busy with background work.
+
+  **Web-tab changes stay private in multi-user mode (#501).** The `webview:changed` event reached every connected user, exposing the ids of other users' web-tab creates, edits and deletes. It now carries the tab's owner and reaches that owner plus admins only. Single-user mode is unchanged apart from a new optional `owner` field on the event.
+
+  **Phone header tabs look like tabs (#504).** On phones every header tab is now a chip with a fill and a border, the Alt+N digit (a keyboard hint a phone cannot use) is hidden, names get 80px instead of 50px, and the strip fades at whichever edge still has tabs scrolled out of view.
+
+  **Docker: CLIs installed from Settings survive container updates (#490).** On the Compose deployment, CLIs installed from App Settings (DeepSeek, Pi and other npm-based CLIs) now go to `~/.local` on the persistent home mount, and `~/.local/bin` is on the image PATH, so recreating the container no longer discards them. Anything installed from Settings before this release has to be installed once more after the rebuild.
+
+  **Docker: a static Git identity for the server and agent images (#492).** Set `GIT_USER_NAME` and `GIT_USER_EMAIL` in `docker/.env` (or `CODEMAN_AGENT_IMAGE_GIT_USER_NAME` / `CODEMAN_AGENT_IMAGE_GIT_USER_EMAIL` on a bare-host install) and the identity is written to `/etc/gitconfig` in the server image and the Docker-case agent image. A half-set pair is refused on every build path. Both Docker changes edit `server.Dockerfile`, so the in-app updater asks Compose deployments to rebuild with `docker/Start-Codeman.sh` instead of updating in place.
+
+  **Contributor tooling (#500).** `npm run check:browser-excludes`, now a CI step, fails when a test that drives a real browser is still collected by `npm test`. `npm install` also installs a pre-push hook that runs the static CI checks before a push; it steps aside when the pushed ref is not HEAD or the tree has uncommitted changes the checks would read, and `CODEMAN_SKIP_PREPUSH=1 git push` skips it once.
+
+  **Fixes applied while landing.** A Shell pane's scroll-to-top (#494) no longer re-pulls the same window on every gesture once the browser's 50,000-row scrollback is full, and a pull that hit the byte cap no longer claims the older history is gone. The scroll-routing diagnostics (#498) now log whether Claude has mouse tracking on. The artifact-comment check (#491) also refuses a footer cut off in the middle of the chip. The pre-push hook (#500) steps aside when `npm` is not on PATH, as in some GUI git clients, instead of blocking every push. The Docker Git identity error (#492) names the two variables to set. New tests pin the image PATH order, the identity on both agent-image build paths, and the `?full=1&tail=` terminal route.
+
+## 1.33.1
+
+### Patch Changes
+
+- ### Thanks
+  - @irisitymichaelgrundberg for closing sessions whose agent exited cleanly (#486), built carefully around every way a pane exit can lie (a SIGKILL with no status, a single misread), with the `.claude-images` guard split into its own commit as asked.
+  - @opticon454 for the live-refreshing case picker and Manage search (#483), and for the uv/uvx, libsecret and pnpm additions to the Docker images (#487, #485).
+
+  **Finished sessions close themselves (#486).** A session whose agent you ended with `/exit` is now closed the same way the X button closes it, so finished sessions stop piling up on the board; the conversation stays resumable from the Resume list and the lifecycle log records "agent exited cleanly (status 0)". Only an explicit exit status 0 with no signal, confirmed by two pane reads, qualifies: a crashed or OOM-killed agent keeps its row with the exit code on the tab. The phone overview and desktop home rail now say `exited` instead of `idle`, reboot restore no longer offers to rebuild a session whose agent had exited, and closing one session no longer deletes the `.claude-images` directory that a sibling session in the same case still uses. Thanks @irisitymichaelgrundberg.
+
+  **Search in the phone Select Case sheet (#488).** The bottom sheet gains a "Search cases" field that filters by name (every word must match, any order, ignoring case), Enter picks the case when exactly one row is left, and Escape clears then closes. Also fixes a dead band under Create New Case and a list shorter than the sheet could show.
+
+  **An oversized paste no longer jams a session's input (#484).** A single input over the 64 KiB frame limit used to be refused by both transports, retried every 2 s forever, block every later input for that session and come back from localStorage on each reload. Pastes over the limit are now split into in-limit frames delivered in order (up to 1 MiB; larger ones are refused with a toast and never queued), a refused frame is dropped instead of retried, frames persisted by an older build are pruned on load, and the WebSocket answers an oversized frame with an explicit `too_large` error instead of silence.
+
+- 8841bcc: Add a search box to the Manage tab of the Add Case dialog. It filters the case list by name or path, and the reorder arrows are disabled while a filter is active so a swap cannot involve a hidden case.
+- 8841bcc: The case picker now refreshes its list from `/api/cases` when it opens and every 5 seconds while it stays open, so folders deleted or created on disk appear without a page reload. If the selected case has been removed, the picker falls back to another case without saving it as the last-used one.
+
+  Thanks @opticon454.
+
+- 77ba41f: Install `uv` and `uvx` in the Compose server image and the agent image, so MCP servers launched with `uvx` (such as the Nginx Proxy Manager MCP) can be enabled by Codex instead of failing with `uvx` not found. Both images also install `libsecret-1-0`, the native library the `keytar` dependency of the Azure DevOps MCP (`@azure-devops/mcp`) needs; without it the server crashes before answering the MCP initialize handshake.
+
+  The Compose server image now also carries `pnpm`: `dsh plugin` spawns a literal `pnpm` with no npm fallback, so the Run menu's "DeepSeek - add a terminal profile" button failed with `dsh: pnpm not found on PATH` there. Because this release changes `server.Dockerfile`, the in-app updater asks Compose deployments to rebuild the image (`Update-Codeman.sh`) rather than applying it in place.
+
+  Thanks @opticon454 (#487, #485).
+
+## 1.33.0
+
+### Minor Changes
+
+- CLI management from Settings (#476, finishing the CLI registry work from #343). `~/.codeman/clis.json` used to be hand-edit only; with the new opt-in `cliManagementEnabled` switch (synced, default OFF) App Settings → Agents & CLIs can enable or disable any CLI, install a missing stock CLI with its vetted install command, and add, edit or remove custom CLIs. Six new endpoints back it (`GET`/`POST /api/clis`, `PUT /api/clis/:id`, `POST /api/clis/:id/install`, `PUT /api/clis/custom/:id`, `DELETE /api/clis/:id`), documented in `docs/api-reference.md`. Every write is refused while the switch is off, is admin-only in multi-user mode, is serialized on one queue, and refuses to overwrite a `clis.json` that does not parse or has group/world permission bits. A custom entry is re-validated through the same schema as the stock ones and its install text is never executed. `shell` cannot be disabled. The Run menu and the welcome screen are now built from the enabled catalogue, so the welcome screen also offers Codex, Shell and any custom CLI, and the stock Claude entry is labelled "Claude Code".
+
+  Models: Opus 5.5 (`claude-opus-5-5`, 1M context capable) is offered in App Settings → Models and in task routing (#480).
+
+  Self-update: on a macOS `launchd-daemon` install, a Homebrew node upgrade could leave `update-status.json` stuck at `queued`, which made every later update fail with "An update is already in progress." The updater now falls back to `node` on PATH when the server's own node binary is gone, and an in-flight status that has not been written for 15 minutes is failed on the next read. A graceful shutdown that hangs is now force-exited after 10 s (and the launchd updater SIGKILLs a server that has not exited after 30 s), so launchd can start the new build instead of leaving the service down (#478). Both fixes protect updates that start FROM this release.
+
+  Session Manager (Cmd+K): rows keep their `mode`, `claudeSessionId` and `resumeId`, so the ⋯ menu's Resume session relaunches a Codex row as Codex on its own conversation, and the mode badge shows as it does on the home list (#477).
+
+  Maintainer fixes applied while landing #457: renaming a tab to the name it already has (the Session Options field saves on blur) is now a no-op, so it no longer pins the placeholder as the `/resume` title again; Docker sessions skip the transcript title sync, since their transcript lives in the container; and the agent skill's messaging examples no longer use a `w<N>-` name as the peer name.
+
+  Tests: the suite strips every inherited `CODEMAN_*` variable, so running it inside a Docker Compose deployment no longer writes into the deployment's real case root (#479).
+
+  ### Thanks
+  - @opticon454 for CLI management (#476), the last piece of the CLI registry, with every review item answered in one round, and for splitting the test isolation fix out into #479.
+  - @shenlvkang-collab for the `/resume` title fix (#457) and the careful diagnosis behind it.
+  - @julian3xl for the Session Manager row fix (#477), their first contribution.
+
+### Patch Changes
+
+- 69a7128: fix(sessions): stop pinning the `w1-myapp` placeholder as Claude's session title. Local Claude spawns passed the tab name as `--name`, which is also the `/resume` picker entry and the terminal title, and a pinned title stops Claude generating its own, so every conversation of a case showed up in `/resume` as the same `w1-myapp` and none got a generated title. Only a name the user chose is pinned now; placeholder and auto-named tabs let Claude title the conversation again. Renaming a Claude tab also reaches `/resume`: the new name is appended to the conversation's transcript as the `custom-title` row `/rename` writes (a tab that was spawned with `--name` keeps re-appending its own title until its next respawn, so the rename wins from then on). Orchestrators that rely on a fixed peer name should give workers a descriptive `sessionName` rather than a `w<N>-` one.

 - **Never `git add -A`/`git add .`** — stage explicit paths. A sweep will pick up another session's WIP.
 - Another session's broken WIP can block `npm run build`, since `tsc` is the first step and the build gates on it. That is not your bug to fix. ⚠️ `tsc` still EMITS on type errors, so a failed `npm run build` leaves a rebuilt `dist/index.js` compiled from their tree; check what it pulled in before restarting the service. To deploy frontend-only changes past a blocked `tsc`, run the asset stage of `scripts/build.mjs` (everything after the `tsc`/`chmod` lines is independent of it).
+- **A pre-push failure in a file you did not touch is another session's WIP.** Push with `CODEMAN_SKIP_PREPUSH=1 git push` and leave it alone. (The hook already skips itself when the tree has uncommitted changes in a path it checks, so this mostly happens once the other session has committed.)

 ## 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

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
 - **ESM only** — Never `require()`, use `await import()`. `tsx` masks CJS/ESM issues in dev but production breaks
 - **Package ≠ product name** — npm: `aicodeman`, product: **Codeman**. Release renames tags accordingly. Both `aicodeman` and `codeman` bin aliases are installed (`package.json` `bin`)
 - **Global regex `lastIndex`** — Shared `g`-flag patterns in loops must reset `lastIndex = 0` first, or use the `execPattern()` helper in `utils/regex-patterns.ts` (resets automatically)
 - **`envOverrides` flow `CLAUDE_CODE_*` / `OPENCODE_*` / `CODEX_*` / `GEMINI_*` / `GOOGLE_*` / `ANTIGRAVITY_*` / `PI_*` / `GROK_*` / `XAI_*` / `DSH_*` / `DEEPSEEK_*` env vars, plus exact-key `CLAUDE_CONFIG_DIR`** — Set via `POST /api/sessions { envOverrides }`, stored on `Session._envOverrides`, exported by `tmux-manager.buildEnvExports()` at spawn time, persisted in `SessionState.envOverrides`. **Do NOT** write these to `<case>/.claude/settings.local.json` — that's the old path and creates UI/disk drift. (`GOOGLE_*` is the deliberately-broad Vertex-AI namespace for Gemini — see Multi-CLI prefix discipline.) `CLAUDE_CONFIG_DIR` (#255, exact match via `ALLOWED_ENV_KEYS` in `schemas.ts`) points a session at a separate Claude account/config dir for per-client subscriptions; it persists to state.json (a path, not a secret; losing it on restart would silently switch accounts). ⚠️ A relocated config dir writes transcripts outside `~/.claude/projects`, so the response viewer, subagent windows, ultracode panel and Read My Mind capture go blind for that session unless the user symlinks `projects` back into the shared tree (`ln -s ~/.claude/projects <configDir>/projects`). ⚠️ It is also one of claude's `privilegedEnvKeys` (Custom Model Endpoint Profiles, since it can redirect a session's traffic same as any other injected var), so in multi-user mode setting it via `envOverrides` is admin-only, and a non-granted owner's already-persisted `CLAUDE_CONFIG_DIR` is stripped on reboot-restore — silently returning that session to the default Claude account rather than the one it was pointed at (see `session-env-clamp.ts`). → [architecture-invariants#per-session-env-overrides-exact-key-allowlist-and-claude_config_dir](docs/architecture-invariants.md#per-session-env-overrides-exact-key-allowlist-and-claude_config_dir)
 - **Effort is NOT an env var** — never carry effort as `CLAUDE_CODE_EFFORT_LEVEL`: the env var hard-locks effort and blocks in-session `/effort` switching (incl. ultracode). It flows as the dedicated `effort` payload field → `Session._effort` → `claude --effort <level>` for regular levels incl. `max` (the settings `effortLevel` key is `enum(["low","medium","high","xhigh"]).catch(undefined)` — `max` gets SILENTLY dropped there), or `claude --settings '{"ultracode":true}'` for ultracode (rejected by `--effort`). Both are soft defaults the user can override anytime. Legacy env-var entries are auto-migrated by the Session constructor and unset from tmux sessions in `applyEnvOverrides()`. See `buildEffortCliArgs()` in `session-cli-builder.ts`, tests in `test/effort-injection.test.ts`
-- **Model choice flows via `settings.local.json`, NOT `--model` or env** — the App Settings **Claude Model** picker (`claudeModel` in `settings.json`) is read by `session-ui.js` at session create (wins over the legacy 1M-Opus toggles `opusContext1m`/`opusContext1mEnabled`), sent as the `modelOverride` payload field, and `updateCaseModel()` (`hooks-config.ts`) writes/deletes the `model` key in `<case>/.claude/settings.local.json`. This is the intended exception to the envOverrides rule above: model legitimately lives in `settings.local.json` (a soft default — in-session `/model` still works); env vars do not
+- **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. Resolver design pattern: `docs/opencode-integration.md`, `docs/pi-integration.md`, `docs/grok-integration.md`, `docs/deepseek-integration.md`
 - **Zod `.optional()` rejects `null`** — accepts `undefined` only. When the frontend builds a request body with `JSON.stringify`, an explicit `null` field is preserved on the wire and fails validation with `INVALID_INPUT`. Convert `null` → `undefined` before stringifying (e.g. `field: value ?? undefined`), or declare the schema `.nullish()`. This has caused real shipped bugs twice
 - **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`.

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)
 - **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.

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.

 ## More Features
 
 - **Background daemon & service install** — `codeman web -d` runs the server detached with a pidfile, `~/.codeman/web.log`, and verified startup (it polls the server until it answers, so a port clash never reads as success); `codeman service install` writes a systemd user unit (Linux) or LaunchAgent (macOS) with your shell's PATH baked in, so an nvm or Homebrew `node`, `tmux` and `claude` are actually found. Secrets are never written into unit files
+- **Diagnostics in Settings** — **App Settings → System → Diagnostics → Run checks** runs `codeman doctor` on the server and lists Node, tmux, every agent CLI and the optional office tools with versions, paths and install hints. Besides the `PATH`, it also looks in each CLI's usual install directories (`~/.local/bin`, `~/.npm-global/bin` and the like), so most installs are found under a service with a minimal `PATH`. Admin only in multi-user mode.
 - **Self-update** — git-clone installs under systemd/launchd update in place from **App Settings → System → Updates**: it detects the latest release, auto-stashes a dirty tree, and streams build progress across the service restart (npm installs report as non-updatable)
+- **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.
 - **Multi-CLI** — run **Claude Code**, **OpenCode**, **Codex**, **Antigravity**, **Gemini**, **Pi**, **Grok**, **DeepSeek Harness**, or **OMP** per session; env-var prefixes auto-gate (`CLAUDE_CODE_*` vs `OPENCODE_*` vs `CODEX_*` vs `ANTIGRAVITY_*` vs `GEMINI_*`/`GOOGLE_*` vs `PI_*` vs `GROK_*`/`XAI_*` vs `DSH_*`/`DEEPSEEK_*` vs `OMP_*`). See [`docs/opencode-integration.md`](docs/opencode-integration.md), [`docs/pi-integration.md`](docs/pi-integration.md), [`docs/grok-integration.md`](docs/grok-integration.md), [`docs/deepseek-integration.md`](docs/deepseek-integration.md) and [`docs/omp-integration.md`](docs/omp-integration.md)
 - **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)

+## Creating a case in a custom folder
+
+`POST /api/cases` takes `{ name, description?, path? }`. Without `path` it creates `<cases dir>/<name>` as always. With `path` (absolute, or starting with `~`) the case folder is created at that exact path instead, scaffolded the same way (`CLAUDE.md`, `src/`, `.claude/settings.local.json`), and registered in the linked-cases registry, so it lists, resolves and deletes like a linked case (deleting unlinks; it never removes files). Response: `{ case: { name, path } }`, where `path` is the symlink-resolved folder.
+
+The target is judged before anything is written:
+
+- It must be absolute with no `..` and none of the shell metacharacters a session working directory is rejected for (spaces are fine). `400 INVALID_INPUT` otherwise.
+- It must not be a system directory (`/etc`, `/usr`, `/proc`, ...), the home folder itself, Codeman's own data folder, or a credential/config tree (`~/.ssh`, `~/.aws`, `~/.claude`, ...). Judged on the path as typed and on its symlink-resolved form, against both the given and the symlink-resolved roots. `400`.
+- It must not be, or be inside, the cases directory (the caller's own and the shared one): a case there is a plain create without `path`. `400`.
+- Its parent must already exist (one folder is created, never a chain): `404 NOT_FOUND`. A parent that does not answer (an unreachable network mount) or cannot be read is `422 OPERATION_FAILED`, checked through the bounded path probe before anything else touches it.
+- The folder must not exist, or must be an **empty** directory; a folder with contents is Link Existing's job: `409 ALREADY_EXISTS`. A symlink or a plain file at the target is `400`.
+- `409 ALREADY_EXISTS` also for a case name already in use (in the cases dir or the registry) and for a folder that is already a case.
+
+Admin only in multi-user mode (`403`), like `POST /api/cases/link`: it writes outside the cases directory and into the shared, ownerless registry. If anything fails after the first write, what this call created is removed (the whole folder if it created it, otherwise only the scaffold inside the empty folder you picked) and the response is `500`.
+
+## Git status
+
+`GET /api/sessions/:id/git-status` is what the bottom-bar Git indicator and its panel read (Settings → Header & Panels → Bottom bar, per-device, default off). It reports what the session's workspace has not committed or pushed. **Read-only and offline:** it never fetches, pulls, commits or writes (it runs `git status` with `--no-optional-locks`, so it does not even refresh the index), which is why `behind` is as of the last `git fetch`. The session is resolved like every session route (ownership via `findSessionOrFail`; another user's session is `404`). A repository whose root is, or is inside, a Docker case workspace is dropped (from the walk-up, the scan below a folder, and the diff route): a container can write there, and a repository's own clean filter or signature program would run on the host. When a branch's upstream does not exist on the remote (deleted and pruned, or never pushed, as after cloning an empty repository and committing), `upstreamGone` is `true` and the unpushed list falls back to commits on no remote-tracking ref at all.
+
+`GET /api/sessions/:id/git-diff?repo=<repoRoot>&path=<path>&kind=staged|unstaged|untracked|conflicted` returns the unified diff of one file the panel lists (`{ diff, truncated, binary }`; staged is index vs HEAD, unstaged is working tree vs index, untracked is the whole file as additions). It is what opens when you click a file in the Git panel. `repo` and `path` are matched against the current status rather than trusted, so anything the status does not list is `404`. Read-only: it passes `--no-ext-diff --no-textconv` (no external diff or textconv driver runs), but a repository's clean filters still run, as they do for any `git diff`, which is why a repository a container can write to is never inspected (below). Capped at 400 KB, and refused (`400`) for remote and Docker sessions; a repository at or inside a Docker case workspace is not in the status, so it is `404` here.
+
+**Which repositories.** git finds a repository by walking *up* from the session's working directory, so:
+
+- Inside a repository (or at its root): that one repository, whole (a subfolder reports its enclosing repo, `path` says where it is, e.g. `../..`). A nested repo below it is just an untracked folder to the outer one and is not scanned; start the session inside it to see it.
+- **Not** inside one (a folder that holds several projects): every repository found up to **two levels down**, nearest and alphabetical first, at most 12 (`reposTruncated` says when there were more). Dot-folders, `node_modules`, `dist`, `build`, `target`, `vendor`, `venv` and `__pycache__` are skipped, symlinks are never followed, and a repository's own contents are not searched. The list of repositories is re-scanned at most every 30 s; each repository's status is cached for 4 s.
+- A repository that merely sits **above** the workspace and is the home folder or higher (a dotfiles repo in `$HOME`, or `/`) is ignored: its dirty files are not this session's work. A workspace that *is* that repository's root is not ignored.
+- A worktree (whose `.git` is a file) counts as a repository. A submodule's own uncommitted files are not reported, only a changed submodule pointer.
+
+`data` is `{ state, repos, reposTruncated, checkedAt }`:
+
+- `state: 'ok'`: `repos[]`, each `{ name, path, status }` where `name` is the repository folder's name, `path` its root relative to the working directory, and `status` is:
+  `branch` (null when `detached`), `upstream`, `ahead`, `behind`, `hasRemote`, `counts` (`staged`, `unstaged`, `untracked`, `conflicted`, `uncommitted` = distinct paths, `stashes`), `files[]` (`path` relative to `repoRoot`, `origPath` for a rename, `index` and `worktree` status letters, `kind`: `staged` \| `unstaged` \| `untracked` \| `conflicted`; a file that is staged *and* modified again appears once per kind), `filesTruncated`, `unpushedCount` (exact) and `unpushed[]` (newest first: `hash`, `author`, `time` in epoch seconds, `subject`), `repoRoot`, `checkedAt`.
+- `state: 'not-a-repo'`: no repository here, above (that counts) or within two levels below.
+- `state: 'unsupported'` with `reason: 'remote' | 'docker'`: those sessions are never inspected (a Docker workspace is writable from inside its sandbox, and git here would run on the host).
+- `state: 'error'` with a short `error` (git missing, timed out, or git's first stderr line with any `user:token@` credentials redacted).
+
+Lists are capped (300 files and 50 commits per repository) while the counts stay exact. A branch with no upstream reports the commits no remote has (`HEAD --not --remotes`); a repository with no remote reports `unpushedCount: 0`, since there is nothing to push to. Concurrent polls of one folder share a single git invocation; `?fresh=1` (what the panel's Refresh button and opening the panel send) skips the short-lived caches, though it still joins a computation already running.
+
+## CLI management
+
+Read and write the CLI registry (`docs/cli-registry.md`). Every **write** route answers `403 FORBIDDEN` while `cliManagementEnabled` is off (the default), and for a non-admin in multi-user mode. A write that would overwrite a `clis.json` which does not parse, or which has group/world permission bits, is refused with `409 CONFLICT` and a message naming the fix; the file is left untouched.

Never enables the entry. |
+| `POST`   | `/api/clis`                   | `{ id, label, shortBadge, binaries, argv, enabled? }`   | Create a custom entry. `409 ALREADY_EXISTS` for a stock id or an existing custom id. `enabled` defaults to `true`. |
+| `PUT`    | `/api/clis/custom/:id`        | `{ label, shortBadge, binaries, argv, enabled? }`       | Replace an existing custom entry. An absent `enabled` keeps the entry's current state. `400` for a stock id, `404` for an unknown one. |
+| `DELETE` | `/api/clis/:id`               | none                                                    | Delete a custom entry. `400` for a stock id, `404` for an unknown one.                                  |
+
+## MCP server sync
+
+Copies MCP servers between the agent CLIs' own user-level config files (`docs/cli-registry.md`, "MCP server sync"). **Opt-in:** both routes answer `403 FORBIDDEN` while the synced `mcpSyncEnabled` setting is off (the default), and for a non-admin in multi-user mode, because the routes write files in the server user's home. A second `POST` while one is running answers `409 CONFLICT`.
+
+| Method | Path            | Body | Notes                                                                                                                   |
+| ------ | --------------- | ---- | ----------------------------------------------------------------------------------------------------------------------- |
+| `GET`  | `/api/mcp-sync` | none | Dry run. Same result shape as `POST`, with `applied: false`; nothing is written.                                        |
+| `POST` | `/api/mcp-sync` | none | Adds each server a CLI is missing to that CLI's config file. Never edits or removes a server. `500` on an unexpected error. |
+
+Result (`data`):
+
+- `applied` — `false` for the dry run.
+- `targets[]` — one per enabled CLI that declares an MCP config: `id`, `label`, `file`, `status`, `error?`, `servers` (names it already has), `added` (names added, or that would be), `skipped` (names its dialect cannot express, e.g. SSE for Codex and Antigravity).
+  - `status`: `ok`; `absent` (not installed and no config file, so not read or created); `skipped` (the CLI's relocation env var, e.g. `CODEX_HOME`, is set to a relative path in the server's environment, so its file cannot be located safely and is neither read nor written); `unreadable` (the file exists but cannot be parsed safely, so it is not written); `failed` (a read or write error, the file may be unchanged).
+  - `error` says why a target is not `ok`. A parse failure is reported by position only (`not valid TOML (line 3, column 21)`, `not valid JSON`), never with text from the file.
+  - `file` honours each CLI's own relocation env var as the server process sees it (`CLAUDE_CONFIG_DIR`, `CODEX_HOME`, `XDG_CONFIG_HOME`, `GEMINI_CLI_HOME`); see `docs/cli-registry.md`.
+- `conflicts[]` — names defined differently by different CLIs. Existing definitions are kept; the first CLI's is copied where the name is missing.
+- `disabled[]` — names left out because every definition is switched off in its own CLI (codex `enabled = false`, opencode `enabled: false`, antigravity `disabled: true`).
+- `unsupported[]` — labels of enabled agent CLIs with no known MCP config file (nothing is guessed).
+  - Only installed CLIs are listed: one that is not installed is left out, as a supported CLI that is not installed reads `absent`.
+
+The result carries server **names** only, never `env` values, `headers` or file content. Each changed file keeps its previous content as `<file>.codeman-bak` (overwritten by each sync); a file that receives servers carrying `env` or `headers` is left mode `0600`.
+
+## 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.
+
+| Method | Path                 | Body                                         | Notes |
+| ------ | -------------------- | -------------------------------------------- | ----- |
+| `GET`  | `/api/webhook`       | none                                         | `{ enabled, kind, scope, hasUrl, urlMasked, lastResult }`. `urlMasked` is scheme + host only. `lastResult` is the last delivery (`ok`, `status?`, `error?`, `at`) or `null`. |
+| `PUT`  | `/api/webhook`       | `{ enabled?, kind?, scope?, url? }` (strict) | `kind`: `ntfy` \| `slack` \| `discord` \| `generic`. `scope`: `attention` (skip "response complete") \| `all`. An absent `url` keeps the saved one; `""` clears it. `400` for a non-http(s) URL, `user:pass@`, a link-local or cloud-metadata target, or enabling with no URL. |
+| `POST` | `/api/webhook/test`  | none                                         | Sends one message with the saved config, even while disabled. `200` with `data.ok` telling whether the webhook accepted it; `400` if no URL is saved. |
+
+Delivery goes through the same egress guard as web tabs (refused on the resolved address too), does not follow redirects, times out after 5 s, sends the same event for the same session at most once per 3 s, and has at most 5 requests in flight. Error text never contains the URL.
+
+## Diagnostics
+
+`GET /api/doctor[?category=core|office|other]` returns the `codeman doctor --json` report (`platform`, `summary`, `tools[]` with `status` `ok` \| `missing` \| `outdated` \| `skipped` \| `error`, `version`, `path`, `installHint`). The probe engine is synchronous, so it runs in a child process of the same entry script, never on the server's event loop (30 s timeout). It names install paths and versions, so it is admin only in multi-user mode (`403`). `400` for an unknown category, `500` if the child produces no report.

+## Status as of 2026-09-22
+
+**Phases 1–6 are ALL IMPLEMENTED** (commits `da07b38c` "add cliManagementEnabled flag and GET
+/api/clis" and `db4557d9` "Phases 3-6 - write API + custom entries + Settings UI", both on this

+`isAdmin(req)` gating on both the list and write routes; `appendAdminAudit` wired into the install
+route; tmp+rename+`0o600` writes in `registry-writer.ts`; the full Settings UI (row list, toggle,
+Install button, custom-entry create/edit/delete form) in `settings-ui.js` + `index.html`.
+`test/routes/cli-registry-routes.test.ts` (425 lines) and `test/cli-registry-no-id-branching.test.ts`
+cover it. This status section, plus the fix and gap below, is the one piece of that work done in
+a *different* session from the one that wrote Phases 1–6 — reviewed by reading the diff and
+verifying each claim against the actual routes/tests, not by re-implementing anything.
+
+### Gotcha found and fixed (commit `0c77dd0a`)
+
+**Toggling a CLI off in Settings had no effect anywhere except the Settings row itself.**
+`window.__codemanCliAvailable` — the flag `isCliAvailable()` reads client-side to gate the
+welcome-screen buttons, the Run-menu dropdown and the mobile overview — is injected **once**, at
+initial page render (`server.ts`), built purely from each CLI's own installed-on-PATH resolver
+(`isClaudeAvailable()` etc.), with **no reference to the registry's `enabled` flag at all**. So
+disabling a CLI here updated its own row and nothing else — every launch surface kept offering it,
+both live and after a full page reload, since even a *fresh* render never consulted the registry.
+Root-caused and reported by the user testing the live feature ("toggle those off, they still
+appear in that menu and on the front main screen").
+
+Fixed two places:
+- `server.ts`: after building `available`, intersect the nine real `SessionMode` ids against
+  `enabledClis()`. `git`/`cloudflared` (utility binaries, not CLI registry entries) and
+  `deepseekBinary` (a secondary installed-only flag for the "add a profile" affordance) are
+  deliberately left alone — they were never registry-gated to begin with.
+- `settings-ui.js`: `toggleCliEnabled()` now patches `window.__codemanCliAvailable` in place and
+  refreshes the welcome screen, the mobile overview and an already-open Run menu, mirroring the
+  existing `installDeepSeekProfile()` pattern for the same "injected once, needs an explicit
+  patch" reason — the server-side fix alone still left every surface stale until the next reload.
+
+New test in `test/render-index-html.test.ts`: an installed-but-disabled CLI (codex, forced via
+`clis.json` + `reloadCliRegistry()`) reads as unavailable, while an installed-and-enabled one
+(claude) is unaffected by the override.
+
+**Verified on the Debian devbox** (`codeman-devbox`, real tmux — this sandbox has none and
+`WebServer`'s constructor hard-requires it): typecheck clean, the new test passes (17/17 in
+`render-index-html.test.ts`), the CLI-registry suites pass (86/86), and the **full CI gate is
+green — 415 test files, 7855 tests, 0 failures**.
+
+### Launch-surface registry integration — completed
+
+The welcome screen, desktop Run menu and mobile Run picker now use the same injected CLI catalog.
+Every enabled registry entry is rendered; unavailable binaries remain hidden as before. Settings
+updates the catalog and availability flags in place after enable/disable, create, edit or delete,
+so the launch surfaces update without a page reload. A custom entry uses the generic quick-start
+path, while stock entries retain their existing per-CLI launch settings.
+
+Not otherwise re-verified line-by-line against every Phase 1–6 checklist item below (e.g. the
+exact wording of toasts, the "same PR" sequencing notes) — the checklists are left as originally
+written; treat the **Status** section above as authoritative for what exists.
+
+---
+
+## Background
+
+`src/config/cli-registry/registry.ts` is READ-ONLY today, and says so in its own header comment:
+
+> "⚠️ READ-ONLY. Nothing in this module writes, creates or migrates the file... there is no
+> settings UI and no write API yet... A `seededStockIds` ratchet belongs with the write API that
+> needs it."
+
+Confirmed on `master` (2026-09-21): no `/api/clis` route exists at all (read or write);
+`~/.codeman/clis.json` is hand-edit-only; `resolveInstallCommandForPlatform()` is documented
+"Display text only — never executed" — nothing runs an install command server-side today. The
+original #343 review flagged the opposite (`spawn(command, {shell: true})`, `env.allowedPrefixes`
+contributed from a write) as needing its own trust-model decision; that decision was never made
+after the split, just dropped. This plan makes it.
+
+**Closest existing precedent, and the template this plan follows for the read/write API**:
+`src/web/routes/custom-model-routes.ts` + `src/custom-model-hosts.ts` (#393/#430/#459) — a small
+per-item JSON store, Settings-UI-driven, admin-gated in multi-user mode, tmp+rename+0600 writes.
+
+**Precedent for the new master feature flag (Phase 1)**: `customModelEndpointsEnabled` —
+`z.boolean().optional()` in `SettingsUpdateSchema` (`schemas.ts:1319`), a checkbox read/written by
+id in `openAppSettings()`/`saveAppSettings()` (`settings-ui.js:401`/`:2120`). SYNCED, not
+per-device (present in the schema, absent from `displayKeys`), default OFF.
+
+**Spec refs for the whole plan:**
+- `src/config/cli-registry/registry.ts` — the read path; `resolveRegistry()`'s merge semantics
+  (`deepMerge`, `UNMERGEABLE_KEYS`) apply unchanged to whatever this plan writes
+- `docs/cli-registry.md` — registry shape, "The override file", "Arg-template safety" (the four
+  layers Phase 5's custom-entry validation must not weaken), "Adding a CLI" (the 5-step recipe a
+  custom entry does NOT get to skip just because it arrives via UI instead of a stock.ts edit)
+- `src/web/routes/custom-model-routes.ts` + `src/custom-model-hosts.ts` — read/write API template
+- `docs/multi-user-plan.md`, `docs/security-architecture.md` — admin-gating conventions
+- `CLAUDE.md` §Multi-user mode, §"Settings surface", §"Per-device vs synced settings"
+
+---
+
+## Decisions (Phase 0, closed 2026-09-21)
+
+1. **Enable/disable a stock CLI's `enabled` flag** — IN SCOPE. Plus a **master feature flag**
+   (`cliManagementEnabled`, synced, default OFF) gating the whole Settings UI section's visibility,
+   matching this codebase's standing convention for new admin-facing surfaces.
+2. **Auto-install** (stock CLIs' already-shipped, already-vetted install commands) — IN SCOPE,
+   same PR.
+3. **Custom CLI entries via the UI** — IN SCOPE, **typed-argv only**: a custom entry goes through
+   the exact same schema/argv-safety path stock entries do (named token patterns, no raw shell-text
+   field). Its install command stays **display-only text**, same as every stock entry today — Phase
+   4's auto-install NEVER executes a custom entry's install command, only a stock one's. This is
+   the one place scope was deliberately narrowed relative to what was agreed in principle, because
+   `docs/cli-registry.md`'s arg-template-safety section exists specifically to keep config free of

+
+## Phase 1 — Master feature flag: `cliManagementEnabled`
+
+**Status:** DONE (commit `da07b38c`) — verified present in `SettingsUpdateSchema`, `index.html`,
+`openAppSettings()`/`saveAppSettings()`.
+
+**Spec refs:**
+- `schemas.ts:1319` (`customModelEndpointsEnabled`) — the exact pattern to mirror: `z.boolean().optional()`
+  in `SettingsUpdateSchema`
+- `settings-ui.js:401`/`:2120` — checkbox read/write by id in `openAppSettings()`/`saveAppSettings()`
+- `CLAUDE.md` §"Adding Features" → "App setting" — decide per-device vs synced FIRST (this one is
+  synced: a feature toggle, not a display preference) and add to `displayKeys` NEVER for a synced
+  setting
+
+**Checklist:**
+- [x] Add `cliManagementEnabled: z.boolean().optional()` to `SettingsUpdateSchema`
+- [x] Add the checkbox to `index.html`'s `#settings-clis` section, above where Phase 6's per-CLI
+      list will render — reads/writes via `openAppSettings()`/`saveAppSettings()` by id, same as
+      `customModelEndpointsEnabled`
+- [x] `readCliManagementEnabled()` helper (mirrors `readCustomModelEndpointsEnabled()` in
+      `custom-model-routes.ts:609`) for the route file(s) in Phases 2-5 to gate on
+- [x] When OFF: `GET /api/clis` still exists but the Settings UI section stays hidden
+      (`applyCliManagementVisibility()`); the write endpoints reject (see Phase 3)
+
+**Verify:** `npm run typecheck` passes; a unit test confirms `SettingsUpdateSchema` accepts/rejects
+the field correctly; toggling it in a fresh browser profile shows/hides the Settings section with
+no server restart.
+
+---
+
+## Phase 2 — Read endpoint: `GET /api/clis`
+
+**Status:** DONE (commit `da07b38c`) — verified present in `src/web/routes/cli-registry-routes.ts`.
+
+**Spec refs:**
+- `src/web/routes/custom-model-routes.ts:730` (`GET /api/model-endpoints`) — multi-user read
+  gating: empty list for a non-admin, never a 403
+- `src/config/cli-registry/registry.ts` — `listClis()` (every entry, including disabled stock
+  ones — this is an admin/settings surface, unlike `enabledClis()`)
+- `window.__codemanCliAvailable`'s resolvers (`isClaudeAvailable()` etc.) — candidate `installed`
+  source; confirm whether to reuse directly or the response needs its own probe (Open Question 4,
+  carried from the first draft — still genuinely open, decide during this phase not before)
+
+**Checklist:**
+- [x] New route file `cli-registry-routes.ts`
+- [x] Response excludes `launch`/`env`/`capabilities`/`overlays`/`discovery`
+- [x] `isMultiUserMode() && !isAdmin(req)` → `[]`
+- [x] Unit tests in `test/routes/cli-registry-routes.test.ts` (admin/non-admin/single-user,
+      disabled stock CLI still present)
+
+**Verify:** `npm test -- test/routes/cli-registry-routes.test.ts` passes; `curl localhost:3000/api/clis | jq`
+shows every stock CLI including disabled ones.
+
+---
+
+## Phase 3 — Write endpoint: `PUT /api/clis/:id` (stock enable/disable)
+
+**Status:** DONE (commit `db4557d9`) — `UNDISABLEABLE_IDS`, admin gate, tmp+rename+0600 all
+confirmed present.
+
+**Spec refs:**
+- `src/web/routes/custom-model-routes.ts:753` + `src/custom-model-hosts.ts:91` — write-path
+  template: `adminOnly` gate, read-modify-write the WHOLE file, tmp+rename+0600
+- `registry.ts:47` (`filePath()` = `dataPath(...)`) and `reloadCliRegistry()` — write to the same
+  resolved path, invalidate the cache on every successful write or the change is invisible until
+  restart
+
+**Checklist:**
+- [x] Body: `{ enabled: boolean }`. Zod schema in `schemas.ts`
+- [x] Gate order: `cliManagementEnabled` → `adminOnly` → shell/claude guard → stock-only guard
+- [x] Rejects disabling `shell` or `claude` (`UNDISABLEABLE_IDS`)
+- [x] Rejects a write for an id that isn't a stock CLI
+- [x] Deep-merges `{ clis: { [id]: { enabled } } }`, preserving other override keys
+- [x] tmp+rename+0600 write, `reloadCliRegistry()` on success
+- [x] Unit tests (`test/routes/cli-registry-routes.test.ts`)
+
+**Verify:** `npm test` full gate green; `curl -X PUT localhost:3000/api/clis/grok -d '{"enabled":false}'`
+then `GET /api/clis` shows the change with no restart; same against `shell`/`claude` returns an
+error and changes nothing; `ls -la ~/.codeman/clis.json` shows mode 0600.
+
+---
+
+## Phase 4 — Auto-install: `POST /api/clis/:id/install` (stock CLIs only)
+
+**Status:** DONE (commit `db4557d9`) — route present, `appendAdminAudit` wired in.
+
+**Spec refs:**
+- `registry.ts:231` (`resolveInstallCommandForPlatform`) — currently "Display text only — never
+  executed"; this phase is what changes that, for stock entries only, with Decision 2's sign-off
+- Original #343 review's exact concern re: `env.allowedPrefixes` contributed from a write — stays
+  out of scope; this phase only ever runs a command, never touches the env allowlist
+
+**Checklist:**
+- [x] Separate endpoint from Phase 3's toggle
+- [x] Gate order: `cliManagementEnabled` → `adminOnly` → stock-entry-only guard
+- [x] `resolveInstallCommandForPlatform(entry)` for the target
+- [x] Bounded execution (timeout, captured stdout/stderr)
+- [x] Does NOT auto-enable on successful install
+- [x] Audit-logged via `appendAdminAudit`
+- [x] Unit tests
+
+**Verify:** a real install triggered via the endpoint against a CLI not currently installed,
+`GET /api/clis`'s `installed` field flips true with no restart; audit log entry present; attempting
+install against a custom entry's id fails with a clear error; full CI gate green.
+
+---
+
+## Phase 5 — Custom CLI entries: create / update / delete via API
+
+**Status:** DONE (commit `db4557d9`) — `POST /api/clis`, `PUT /api/clis/custom/:id`,
+`DELETE /api/clis/:id` all present. Open Question 2 resolved: a **separate** endpoint
+(`PUT /api/clis/custom/:id`), not Phase 3's `PUT /api/clis/:id` widened.
+
+**Spec refs:**
+- `docs/cli-registry.md` §"Arg-template safety" (all four layers), §"Adding a CLI" (the 5-step
+  recipe) — a custom entry created via this API must satisfy the SAME schema (`CliEntrySchema`)
+  every stock entry does; there is no relaxed path for UI-originated entries
+- `registry.ts`'s `resolveRegistry()` — the custom-entry branch (`stock: false`, dropped with a
+  warning on validation failure, never falls back silently) already exists and is unchanged by
+  this phase; this phase only adds a way to WRITE what that branch reads
+
+**Checklist:**
+- [x] `POST /api/clis` (create), full `CliEntrySchema` validation
+- [x] `PUT /api/clis/custom/:id` (update) — separate endpoint from Phase 3's stock toggle
+- [x] `DELETE /api/clis/:id` refuses for any stock id
+- [x] `id` collision check against existing stock ids
+- [x] `discovery.install.command` on a custom entry stays DISPLAY-ONLY
+- [x] Same tmp+rename+0600 write pattern, `reloadCliRegistry()` on every successful mutation
+- [x] Unit tests
+
+**Verify:** `npm test` full gate green; create a custom entry via curl, confirm it appears in
+`GET /api/clis` — **confirm it appears in the Run menu is UNVERIFIED and currently FALSE, see
+"Outstanding" above**; delete it, confirm it's gone and `clis.json` no longer references it.
+
+---
+
+## Phase 6 — Settings UI
+
+**Status:** DONE (commit `db4557d9`) — `#cliListGroup`, row rendering, toggle, Install button,
+custom-entry create/edit/delete form all present in `settings-ui.js`/`index.html`. Manual browser
+verification per the phase's own "Verify" step (flag on/off, non-admin hidden, toggle stops the
+Run menu offering a CLI, create/enable/launch a custom entry, delete it, shell/claude undisableable)
+has **not** been re-run in this session — the toggle→Run-menu leg specifically was BROKEN until the
+gotcha fix above, and the create→launch leg for a custom entry is the confirmed gap in
+"Outstanding".
+
+**Spec refs:**
+- `index.html:2357` (`#settings-clis`) — the existing home; Phase 1's master toggle at the top,
+  then the per-CLI list, then (if `cliManagementEnabled`) a "custom CLI" creation form, all above
+  the existing Codex-only groups
+- `CLAUDE.md` §"Settings surface" — App Settings scrolls, it does not tab-switch
+- `admin-ui.js` — pattern for an admin-only-VISIBLE section (not just admin-only-writable),
+  needed here per Decision 5
+
+**Checklist:**
+- [x] Whole section hidden when `cliManagementEnabled` is OFF, and separately hidden for a
+      non-admin in multi-user mode (`_applyCliManagementAdminGate`)
+- [x] Fetches `GET /api/clis` when the section becomes visible; renders one row per CLI
+- [x] Stock rows: enabled toggle only; `shell`/`claude` rows show the toggle disabled/greyed
+- [x] Custom rows: enabled toggle plus edit/delete affordances
+- [x] "Add custom CLI" form (id/label/badge/binary/argv)
+- [x] Toggle/edit/delete update the row in place
+
+**Verify:** manual browser test per `CLAUDE.md`'s "Always Test Before Deploying" rule — **not yet
+re-run end-to-end in this session**; do this before considering the feature ready to ship, and
+expect the custom-entry-launch step to fail until the Outstanding gap above is closed.
+
+---
+
+## Remaining Open Questions
+
+1. **Phase 2's `installed` source** — resolved: reuses `window.__codemanCliAvailable`'s existing
+   resolvers via `GET /api/clis`'s own probe (confirmed by reading the route).
+2. **Phase 5's `PUT` endpoint shape** — resolved: a **separate** endpoint
+   (`PUT /api/clis/custom/:id`), not Phase 3's toggle route widened.
+3. **Sequencing against the parked Copilot plan** — unchanged, still not blocking.
+4. **NEW: custom-CLI Run-menu integration** — see "Outstanding" above. Not decided or started.
+
+---
+
+Implementation is underway (see Status above); this line is left for history rather than removed —
+the plan was originally approved before Phases 1–6 landed.

+- adds, edits and deletes **custom** entries (id, label, badge, binaries, launch argv). The server re-validates the whole assembled entry through `CliEntrySchema`, so the form cannot bypass the load-time rules.

+These are the only writes to `clis.json`. They are serialized, and a file that does not parse or has unsafe permissions is refused rather than overwritten; fix it (or `chmod 600` it) and retry. The HTTP routes are listed in `docs/api-reference.md` under *CLI management*.

+## MCP server sync
+
+`capabilities.mcpConfig` (`{ path, format, relocation? }`, `path` relative to the home directory) names the file a CLI keeps its user-level MCP server list in and the dialect it is written in. `src/mcp-sync.ts` reads that list from every ENABLED CLI that declares one, and that is installed or already has the file (a CLI that is neither is reported `absent`, never created), and adds any server a CLI is missing from the others. It writes other tools' own config, so it is **opt-in**: `mcpSyncEnabled` (synced, default OFF) gates `GET`/`POST /api/mcp-sync` (403 while off) and the Settings → Agents & CLIs → MCP servers controls. Declared today for claude, gemini, codex, opencode and antigravity; every format was checked against what the CLI's own `mcp add` writes, except opencode's (documented, not installed to check). A CLI with no entry (pi, grok, omp, deepseek) is not guessed at: it is listed as `unsupported` in the result when enabled. Adding one is a registry entry plus a small adapter in `mcp-sync.ts`, and a verified fixture in `test/mcp-sync.test.ts`.
+
+`relocation` (`{ envVar, path }`) names the env var the CLI itself reads to move that file: claude `CLAUDE_CONFIG_DIR` (`.claude.json` under it), codex `CODEX_HOME` (`config.toml`), opencode `XDG_CONFIG_HOME` (`opencode/opencode.json`) and gemini `GEMINI_CLI_HOME` (`.gemini/settings.json`); antigravity follows `$HOME` only, so it declares none. The var is read from the SERVER process env at call time, which is the env the CLIs Codeman spawns inherit. An absolute value moves the file to `<value>/<relocation.path>`, an empty one counts as unset (as it does for each CLI), and anything else reports the target `skipped` with the reason instead of writing a file the CLI never reads. A per-session relocation (a session's own `CLAUDE_CONFIG_DIR` in `envOverrides`) is not followed: the sync only knows the server's environment.
+
+The rules the module keeps and the tests pin: it only ADDS (a name already defined, in any shape, is never edited or removed; a same-name difference is reported as a conflict); a server switched off in its own CLI is not copied; it never writes a file it could not parse (opencode JSONC with comments, a TOML file with a duplicate table) and re-parses the new text before writing; codex TOML is read with a real parser (`smol-toml`), so CRLF files and inline tables are handled; names such as `__proto__` are ignored and every table keyed by an untrusted name has no prototype; a symlinked config is written through, not replaced; a file that receives `env`/`headers` is left `0600`; only one apply runs at a time; and its result carries server names only, never env values or headers, and never file text: a parse failure is reported by line and column, not by the parser's message (smol-toml prints a code frame of the offending lines and V8's JSON errors quote source, either of which can hold a secret). The schema restricts `path` and `relocation.path` to a relative path without `..`, since sync writes to it.

The same applies to a hand-run `npm install -g` inside a session: it writes to the image prefix (`/opt/codeman-cli`) and is lost on the next rebuild, so use `npm install -g --prefix ~/.local <package>` instead.

+### Opening a session from your own page
+
+To send someone from your page to one session, link to the dashboard with the
+session id in the fragment, as in `http://127.0.0.1:3000/#session=<id>`. The
+dashboard selects that tab when it loads. It also removes the fragment from its
+own URL, so a later link to the same session still counts as a change.
+
+Keep reusing one named window to make later links fast:
+
+```js
+window.open(`${codeman}/#session=${encodeURIComponent(id)}`, 'codeman');
+```
+
+When that window already shows the dashboard, only the fragment differs. The
+browser therefore keeps the page loaded, and the dashboard switches tabs without
+reloading it. A session the window has shown before appears at once. A session
+your page has only just created may not be listed yet, so the dashboard waits
+for its `session:created` event and selects it then. That wait lasts at most 30
+seconds: a link whose session never appears (a closed session, a typo, or in
+multi-user mode another user's session) is dropped with a "Session not found"
+notice. Clicking another tab, going Home or opening a web tab also ends the
+wait, so a session that turns up later never takes the screen from the person.
+
+When your page holds the window reference (`const win = window.open(...)`),
+prefer `win.location.replace(url)` for later links: it still fires `hashchange`
+without a reload, but adds no history entry, so Back in the dashboard window
+does not turn into a silent no-op.
+
+Following a link does not count as someone looking at the session, so it
+leaves the session's idle alert in place. The alert clears when the person
+clicks the tab or types into the session. A link to a session that is popped
+out into its own window asks that window to come forward, as clicking its tab does.
+
+A link to `/session/<id>` opens a page showing that session alone, and that
+page loads from scratch for every link.

Loopback and RFC1918 stay allowed on purpose (a self-hosted ntfy is the point), so **Send test** works as a blind reachability probe (status, refused or timed out, never a response body) for whoever may call it. Web tabs already give that caller full LAN reach with bodies, so nothing new is exposed.
+- **The URL is a bearer secret** (anyone holding a Slack or Discord webhook URL can post as it). It lives in `~/.codeman/webhook.json` (0600, tmp+rename), is kept out of `settings.json` (which every logged-in user reads through `GET /api/settings`), is never returned (`GET /api/webhook` gives scheme + host only), and never appears in a log line, a delivery result or an error message.
+- **It carries session data to a third party.** Titles and bodies include session names, tool names and error text, all agent- or user-controlled, so Discord gets `allowed_mentions: { parse: [] }` and Slack's `& < >` are escaped: agent output cannot ping a channel. In multi-user mode all three routes are admin-only and the channel is instance-wide: it receives every user's session events, the same reach an admin's own Web Push has, which means non-admins' session details leave the box at the admin's choice.

+
+Push needs a browser that subscribed once. A webhook needs nothing on the client side: the

+URL as plain JSON. That makes it the option for a headless box nobody has opened in a browser,

+  `~/.codeman/webhook.json` (readable by its owner only), never in the shared settings, and
+  never shows it again: once saved, the box is empty and the hint shows only the scheme and
+  host. Paste a new URL to replace it, or press **Remove URL** to delete it from the server
+  (which also turns the channel off).
+- **On public ntfy.sh, pick a long random topic.** Topics there are not private; the name is

+- **Local targets work.** A self-hosted ntfy on your LAN or on the same machine is fine.
+  Link-local and cloud-metadata addresses are refused, both when you save and when the

+- **Not pushed**: the commits no remote has. A branch with no upstream says so, and so does one whose
+  upstream does not exist on the remote, because it was never pushed or was deleted there ("Upstream
+  not on remote"), which counts every commit on no remote rather than showing a green tick.

 # xterm-zerolag-input

+
+### Minor Changes
+
+- 6aecc3b: ### Thanks
+  - @opticon454 for four PRs in one batch: webhook notifications (#523), MCP server sync (#521), the Shift+Enter keypress fix (#520) and the newline chord plus Key tester (#522). Every review item was answered in one round, and the merge-order map across all four made landing them together easy.
+  - @aakhter for the grouped vertical rail (#517) and its ARIA tree and full-row activation (#519), which give the owner tab-layout API its first frontend, and for the iOS IME composition preview (#499), carried through three careful review rounds including the overlay rework in the zerolag package.
+  - @irisitymichaelgrundberg for per-session Claude models on `POST /api/sessions` (#514) and Codex reasoning effort per session (#515), both kept registry-driven with no CLI id branching.
+  - @timkjr for keeping Pane B painting during a history pull and its "disconnected" marker last in every interleaving (#524), with an old-versus-new table measured in real Chrome.
+
+  **Webhook notifications (#523).** Settings → Notifications → Webhook posts the same events as Web Push (permission prompts, questions, errors, idle) to ntfy, Slack, Discord or any JSON URL, so a headless server can reach a phone with no browser open. Off by default. The URL is a bearer secret: it lives in its own 0600 file (`~/.codeman/webhook.json`), is never returned by the API, and the routes (`GET`/`PUT /api/webhook`, `POST /api/webhook/test`) are admin only in multi-user mode. Delivery goes through the web-tab egress guard (link-local and cloud-metadata targets refused), does not follow redirects, times out after 5 s, dedupes repeats, and neutralises `@everyone`/Slack control characters in agent-supplied text.
+
+  **MCP server sync (#521).** Opt-in (`mcpSyncEnabled`, synced, off by default; `GET`/`POST /api/mcp-sync` answer 403 until it is on). Settings → Agents & CLIs → MCP servers previews or copies each installed, enabled CLI's MCP servers into the others' own config files (Claude, Gemini, Codex, OpenCode, Antigravity). It only adds missing servers, never edits or removes one, skips servers you switched off, keeps a `.codeman-bak` of every file it changes, re-parses the result before writing, writes through symlinked dotfiles, leaves files that receive env values or headers readable by you only, and reports same-name conflicts instead of overwriting. CLIs with no known MCP config (Pi, Grok, OMP, DeepSeek) are listed as unsupported. Adds the `smol-toml` dependency to read Codex's `config.toml` safely.
+
+  **Claude advisor tool.** Claude Code's experimental advisor (a stronger model the session's main model consults at decision points) can now be set per session: an `advisorModel` field on `POST /api/sessions`, `POST /api/quick-start` and `POST /api/ralph-loop/start` (`fable`, `opus`, `sonnet`, or a full id in those families), and a synced App Settings default under Models → Advisor. It rides the launch's one `--settings` JSON rather than the `--advisor` flag, because the flag exits at launch on any pairing the CLI refuses and would leave a dead pane on every respawn. It is persisted, so respawns and both restore paths keep it, and `/advisor` still switches it in-session. Agents using the codeman skill can give their claude workers one with `CODEMAN_WORKER_ADVISOR=opus`.
+
+  **Per-session Claude model (#514) and Codex reasoning effort (#515).** `POST /api/sessions` takes an optional `model` that launches that one Claude session with `claude --model <id>` and writes nothing to disk (`modelOverride` still writes the case default). It is persisted, so both recovery paths relaunch on it. `codexConfig.reasoningEffort` starts a codex session at a chosen effort (`--config model_reasoning_effort=<level>`), and it survives respawn and resume.
+
+  **Grouped vertical rail (#517, #519).** When the owner has tab groups (`/api/tab-layout`), the vertical rail draws them as collapsible sections, with collapse remembered per device, the active row always visible, and lineage arcs anchored to a collapsed group's header. The grouped rail is an ARIA tree with one tab stop and the standard arrow-key model. With no groups, the rail is unchanged byte for byte. Editing groups from the browser comes in a follow-up.
+
+  **iOS IME composition preview (#499).** On iOS Safari, the text an IME is composing (Japanese, Chinese, Korean, and the predictive composition on English keyboards) is now drawn in the terminal before it commits, inside the local-echo overlay when local echo is on. Inert on every other platform. The `xterm-zerolag-input` package gains `setComposition()`.
+
+  **Key tester and newline chord (#522).** Settings → Terminal & Input has a Key tester that shows the keydown/keypress/keyup events the browser reports, to diagnose a device where a shortcut behaves differently. Keys pressed in it never trigger app shortcuts. Shift+Enter's newline chord is now CLI registry data (`capabilities.newline`, line feed by default); no stock CLI changes.
+
+  **Fixes.** Shift+Enter no longer submits the prompt after inserting the newline: the key handler swallowed only `keydown`, so xterm's `keypress` still sent a bare `\r` (#520). Claude sessions created at the same moment (`spawn_workers`, a multi-tab Run) no longer fall out of tmux onto the direct-PTY fallback: the statusLine exporter's temp file name collided within one millisecond (#531). Pane B of the split view keeps painting during a history pull, and its "disconnected" marker stays the last line however a close, a pull and a refresh interleave (#524).
+
+  **Fixes applied while landing.** Webhooks: the App Settings Save button now saves webhook edits too (a refused URL keeps the dialog open with a warning), Send test saves pending edits first, and a Remove URL button clears a saved URL. MCP sync: a config file that fails to parse is reported by line and column only, never by quoting its content, which can hold API keys; the sync follows `CLAUDE_CONFIG_DIR`, `CODEX_HOME`, `XDG_CONFIG_HOME` and `GEMINI_CLI_HOME` from the server's environment and skips a target it cannot place instead of writing a file the CLI never reads; Preview before saving says to save first; and the MCP group is hidden from non-admins in multi-user mode. Grouped rail: a collapsed group's header shows the red or yellow ring of a hidden row that needs you; layout reads rebuild the rail only when something it draws changed, and failed reads back off (5, 10, 20, 40 s) instead of retrying every 5 s forever; a corrupted collapse preference resets instead of disabling collapse; Ctrl+Shift+{ / } only moves a tab within its own group; tapping a group header or row no longer dismisses the phone keyboard; keys pressed on a row's own buttons no longer move tree focus; and screen-reader positions stay correct after a re-sort. Sessions: `model` on `POST /api/sessions` refuses a value starting with a dash, and `model` or `advisorModel` together with `attachRemoteSession` is now a 400 instead of being ignored; non-Claude sessions no longer report or persist Claude's default model. Split view: a refresh queued behind a history pull no longer leaves a second, stale "disconnected" marker above its replay. iOS IME: a composition on an empty prompt now follows the prompt when output or a resize moves it, and the `xterm-zerolag-input` README documents `setComposition()`. The Shift+Enter and Key tester browser tests now drive the shipped handlers instead of copies.

 The cascade order is pending text, then flushed text, then auto-detected buffer text (which is what makes backspace work after tab completion). Backspace "just works" across any combination of typed, in-flight and completed text.
 
+### IME composition
+
+While an input method (Japanese kana, Chinese pinyin, Korean) is still composing, the text is not committed yet, so it is not in `pendingText` either. `setComposition(text)` draws it as an underlined, `aria-hidden` tail right after the pending and flushed text, using the same wrapping and on-screen layout as the rest of the overlay.
+
+```typescript
+const textarea = terminal.textarea!;
+textarea.addEventListener('compositionupdate', (e) => zerolag.setComposition(e.data));
+textarea.addEventListener('compositionend', () => zerolag.setComposition(''));
+// xterm then emits the committed text through onData: add it with addChar()/appendText() as usual.
+```
+
+The composition is visual only: it is never part of `pendingText`, `hasPending` or `state`, so it can never be sent. Control characters and line breaks are stripped from it. `clear()` and `removeChar()` drop it. Because `hasPending` excludes it, re-place the overlay after output or a resize with an unconditional `rerender()`, not one gated on `hasPending`.

 ### Flushed text

+ * Browser-test exclusion check.
+ *
+ * `npm run test:ci` must never try to drive a real browser: CI runners (and any
+ * clean checkout) have no chromium, so such a file dies with
+ * `browserType.launch: Executable doesn't exist` and takes the whole suite with
+ * it. `config/vitest.ci.config.ts` therefore excludes every browser-driven test
+ * via `BROWSER_TEST_GLOBS` in `config/test-suites.ts`. That list is maintained
+ * BY HAND, and a new browser test simply does not appear in it unless someone
+ * remembers. The omission is invisible on a developer machine that has run
+ * `npx playwright install`, where the test passes, and only shows up on a clean
+ * runner.
+ *
+ * Two deliberate design choices:
+ *
+ * 1. **Detection is by CONTENT, not filename.** Matching `*.browser.test.ts`
+ *    would miss the browser tests that predate that convention
+ *    (`inline-rename`, `opencode-resize`, `webgl-fallback`,
+ *    `terminal-copy-shortcut`, `codex-predictive-echo`). What actually makes a
+ *    file dangerous is importing a browser driver, so that is what is tested.
+ *    ⚠️ Only a DIRECT import is seen: a test that reaches playwright through a
+ *    helper module (e.g. `test/mobile/helpers/browser.ts`) is not detected, so
+ *    such a test still has to be added to `BROWSER_TEST_GLOBS` by hand.
+ *
+ * 2. **The exclusion side is answered by vitest itself**, via
+ *    `vitest list --filesOnly`, rather than by re-implementing glob matching

+ *
+ * Why a pre-push hook: the static CI job (lockfile, typecheck, lint, format, frontend
+ * syntax, ...) fails often on things a contributor could have caught locally in seconds,
+ * and finding out after a push costs a full CI round-trip plus a fix-up commit. Running
+ * the same checks before the push surfaces those failures in ~10-40s instead (12s on a fast
+ * workstation, ~35s measured elsewhere; typecheck, format:check and lint dominate).
+ *
+ * Why pre-PUSH and not pre-commit: a commit is cheap and local, a push is what CI and
+ * reviewers pick up. And why the STATIC tier only: the unit/integration suite takes
+ * minutes, which nobody tolerates per push, so a hook that ran it would be bypassed
+ * within a day. The checks below mirror the static CI job.
+ *
+ * ⚠️ The checks read the WORKING TREE, not the commits being pushed. So the hook skips
+ * (with a one-line notice) whenever the two can differ: when HEAD is not the commit being
+ * pushed, and when `git status` shows uncommitted or untracked changes in a path a check
+ * reads ({@link PRE_PUSH_WATCHED_PATHS}). In a checkout shared by several agent sessions
+ * the second case is usually another session's WIP, which must not block this push.
+ *
+ * ⚠️ This installer is deliberately MARKER-OWNED, unlike the older pre-commit installer in
+ * postinstall.js which overwrites whatever it finds. A developer's own pre-push hook must
+ * survive `npm install`.

+ * @fileoverview "What has this session's workspace not committed or pushed?": a read-only git
+ * snapshot of a session's working directory, for the bottom-bar Git indicator and its panel
+ * (`GET /api/sessions/:id/git-status`). Agents leave work uncommitted and unpushed; this makes that
+ * visible without leaving Codeman.
+ *
+ * Split so the parts that matter test without a repo:
+ *   - pure: `parsePorcelainV2` (status output → branch, upstream, ahead/behind, per-file entries),
+ *     `parseCommitLog`
+ *   - IO: `getGitWorkspaceStatus` (a handful of async, bounded, read-only `git` calls), with a short
+ *     single-flight cache so several tabs polling one repo cost one set of git processes
+ *
+ * WHICH repositories. `getGitWorkspaceOverview` answers for the session's working directory:
+ *   - inside a repository (or at its root): that one repository. git finds it by walking UP, so a
+ *     subfolder reports its whole enclosing repo; a nested repo below it is just an untracked folder
+ *     to the outer one, and is not scanned;
+ *   - NOT inside one (a folder that holds several projects): every repository found up to two levels
+ *     DOWN (`MAX_REPOS` of them, skipping dot-folders, `node_modules` and the like, never following
+ *     symlinks), each reported separately;
+ *   - a repository that merely sits ABOVE the workspace and is the home folder or higher (a dotfiles
+ *     repo in `$HOME`, or `/`) is ignored: its dirty files are not this session's work.
+ *
+ * Rules the code keeps and the tests pin:
+ *   - READ-ONLY and OFFLINE. It never fetches, pulls, commits or writes. "Behind" therefore reflects
+ *     the last fetch (the UI says so); "ahead" and the unpushed list are exact against the
+ *     remote-tracking refs already on disk. `--no-optional-locks` keeps `git status` from even
+ *     refreshing the index, so polling cannot contend with the agent's own git commands.
+ *   - Every call is async (`execFile`), bounded by a timeout, and never interpolates a path into a
+ *     shell: the working directory is the process `cwd`, and the only operand-like input is a fixed
+ *     revision range.
+ *   - Output is capped: the counts are exact, the lists are not (`filesTruncated`).
+ *   - git can run helpers a repository configures: a clean filter (`filter.<name>.clean`) still runs
+ *     during `git status` and `git diff`, as it does for any `git status`. A LOCAL session already
+ *     runs as this same OS user, so polling adds no privilege there. What is turned off: the
+ *     filesystem monitor (`core.fsmonitor`), external diff and textconv drivers, and the signature
+ *     program (`log.showSignature`). A repository a container can write to is NOT inspected: a
+ *     Docker session answers `unsupported`, and any repository whose root is, or is inside, a Docker
+ *     case workspace is dropped from the walk-up, the scan below a folder, and the diff route, because
+ *     the container could have planted that config and git here would run it on the host.
+ *   - Remote URLs and git's stderr can embed `user:token@host`; anything that reaches a client goes

+/**
+ * @fileoverview MCP server sync between the enabled agent CLIs.
+ *
+ * Each CLI keeps its own user-level MCP list in its own dialect (`CliEntry.capabilities.mcpConfig`
+ * names the file and the dialect). This module reads every participating CLI's list into one
+ * neutral shape, and adds any server a CLI is missing from the others. The whole feature is
+ * opt-in (`mcpSyncEnabled`, default OFF; the route enforces it) because it writes OTHER tools'
+ * own user config.
+ *
+ * Deliberately conservative:
+ *   - ADDITIVE only. A server already present under a name (in ANY shape, even one this module
+ *     does not understand) is never rewritten and nothing is ever removed. Same name with a
+ *     different definition is reported as a conflict and left alone.
+ *   - A server the user has switched off in its own CLI (codex `enabled = false`, opencode
+ *     `enabled: false`, antigravity `disabled: true`) is not propagated: copying it would
+ *     switch it on in every other CLI.
+ *   - A file that does not parse (e.g. opencode JSONC with comments, a TOML file with a
+ *     duplicate table) is never written, and a write is only made after the NEW text has been
+ *     parsed again and every added server comes back as intended.
+ *   - Only the MCP table is touched; every other key in the file is preserved. Files are
+ *     re-read immediately before the write and replaced via tmp+rename next to the REAL target
+ *     (a symlinked dotfile stays a symlink), with the old file kept as `<file>.codeman-bak`
+ *     (overwritten by each sync).
+ *   - Copied servers can carry secrets in `env`/`headers`: a file that receives any is left
+ *     readable by its owner only.
+ *   - Servers a dialect cannot express (SSE for codex) are skipped and reported.
+ *   - Only one apply runs at a time.
+ *   - A CLI whose file was moved by its own env var (`mcpConfig.relocation`: `CODEX_HOME`,
+ *     `CLAUDE_CONFIG_DIR`, ...) is followed there, as the SERVER env sets it; a relative value
+ *     cannot be located safely, so that target is reported `skipped` and never written.
+ *
+ * The result types (src/types/mcp-sync.ts) never carry env values or headers: those commonly
+ * hold secrets and the result is returned over HTTP. For the same reason a parse failure is
+ * reported by position only (`describeMcpSyncError`): parsers quote the offending source.

+/**
+ * @fileoverview The exited-agent sweep's decision rule (Ark0N/Codeman#446).
+ *
+ * Codeman creates every tmux pane with `remain-on-exit on`, so `/exit` ends the
+ * CLI while the pane, the tmux session and the `tmux attach-session` process
+ * all live on. Part 1 of #446 records that as `SessionState.paneExit`. This
+ * module decides when such a session is closed, the way the X button closes
+ * it, so finished sessions stop piling up on the board.
+ *
+ * The rule closes a session only on a POSITIVE observation of a clean exit:
+ *
+ * - The exit status must be an explicit numeric 0 with no signal. An absent
+ *   status is UNKNOWN, never 0: on tmux 3.2a a SIGKILLed pane reports neither a
+ *   status nor a signal, so reading absence as clean would sweep an agent the
+ *   OOM killer took. A non-zero status or any signal keeps the row, marked with
+ *   the exit, as the crash evidence #210 was filed to keep.
+ * - At least {@link CLEAN_EXIT_CONFIRMING_READS} authoritative pane reads must
+ *   have agreed on that exit. A failed, empty or skipped read counts for
+ *   nothing, because unknown never closes anything.
+ * - No start, attach or relaunch may be in flight for the session. The
+ *   dead-pane branch of `Session._setupOrAttachMuxSession()` respawns an exited
+ *   pane on purpose, and for a few seconds that pane still reads as dead.
+ * - The exit must land at least {@link CLEAN_EXIT_MIN_PANE_LIFETIME_MS} after
+ *   the last start, attach or relaunch finished. A CLI that prints a startup
+ *   error ("not logged in", a bad profile, a config error) and exits 0 would
+ *   otherwise lose its tab, and the error with it, seconds after launch. Its
+ *   row stays, marked `exited (0)`, for the user to read and close.
+ *
+ * Scoping to local mux-backed sessions happens before this rule runs:
+ * `Session.setPaneExit()` forces the field to UNKNOWN for direct-PTY, remote,
+ * docker and discovered sessions, so their `paneExit` never reaches here.
+ *

+/**
+ * @fileoverview Bounded existence probe for user-chosen paths.
+ *
+ * A linked case can live on a network mount (NFS, SMB, sshfs). When that mount
+ * goes unreachable, a hard mount makes `stat()` wait forever. A synchronous
+ * probe (`existsSync`) on such a path blocks the event loop and freezes the
+ * whole web server; even an async `stat()` never settles and permanently holds
+ * one of libuv's few threadpool workers, which every other `fs`, `dns.lookup`
+ * and `crypto` call in the process shares.
+ *
+ * The probe therefore answers one of THREE things, never two:
+ * - `'present'` / `'absent'`: the filesystem answered (ENOENT and ENOTDIR are
+ *   the only errors that mean absent);
+ * - `'unknown'`: it did not answer in `PATH_PROBE_TIMEOUT_MS`, it answered with
+ *   some other error (EIO from a soft mount that gave up, EACCES), or the probe
+ *   was refused (below). "Unknown" is NOT "absent": a caller that would create,
+ *   scaffold or 404 on absence must not do so on unknown.
+ *
+ * And it keeps a dead mount from draining the threadpool:
+ * - one in-flight probe per path, shared by concurrent callers;
+ * - a path whose probe timed out is "stalled" until that stat finally settles.
+ *   Paths NEAR a stalled one are answered "unknown" without a new stat, so one
+ *   dead mount costs one worker, not one per case and file on it. "Near" means on
+ *   the same mount when that mount is a network or FUSE filesystem (NFS, SMB,
+ *   sshfs and the like): under the deepest mount point holding the stalled path,
+ *   with its type, read from `/proc/self/mounts` (procfs, which never waits on the
+ *   dead filesystem). Otherwise it narrows to the stalled path and everything under
+ *   it: when the deepest mount is local (a path typed under a local `/home` can
+ *   reach a NAS through a symlink, and must not take the rest of `/home` with it),
+ *   is `/`, or the table is unavailable (not Linux). Unrelated paths are probed
+ *   normally;
+ * - once `MAX_STALLED_PATH_PROBES` stalled stats are pending, new probes are
+ *   refused process-wide (answered "unknown"), since each would risk another
+ *   worker. Probes merely in flight do not count, so concurrent healthy probes
+ *   never get refused. A caller acting on ONE path at a user's explicit request
+ *   (opening a case, starting a session in it) may pass `{ pastCap: true }`: its
+ *   probe is still bounded and still recorded as stalled if it hangs (so a dead
+ *   path costs at most one worker however often it is retried), but it is not
+ *   refused just because unrelated mounts are dead. Bulk scans (the case list)
+ *   keep the cap; the per-spawn hook and statusLine helpers retry one refused
+ *   probe past it and then skip a path that still answers "unknown", rather than
+ *   touch it with an unbounded call. `pastCap` still stops at
+ *   `PATH_PROBE_STALL_CEILING` (the threadpool size minus one), so explicit
+ *   requests against several dead paths can never take the last worker.
+ *
+ * Both events are logged once (`console.warn`): a path's first stall, and the
+ * cap engaging, so "my case vanished" and "hooks stopped firing" leave a trace.
+ *
+ * Writers should not use this at all: a writer that must tell "missing" apart
