+## 1.11.2
+
+### Patch Changes
+
+- Make Antigravity (`agy`) a first-class CLI everywhere, and stop presenting Gemini CLI as a consumer product now that it is enterprise-only.
+
+  Antigravity was already wired into the session layer, schemas, run-mode menu and remote/Docker command maps, but the surfaces around it were never updated. Gemini keeps full support; Antigravity now sits beside it.
+
+  Fixes:
+  - **Docker cases with `mode: 'antigravity'` were broken.** `docker/agent.Dockerfile` installs its CLIs from npm, and `agy` is not an npm package, so the binary was never in the image and the container died on command-not-found. It now gets its own installer step. The `--dir /usr/local/bin` flag is load-bearing: the installer's default `$HOME/.local/bin` resolves to root's home at build time and would be unreachable by the `agent` user the container runs as. Note the binary is roughly 190MB, making it the largest layer in the image, so rebuild with `node scripts/build-agent-image.mjs` when convenient.
+  - **Welcome screen** gained a "Run Antigravity" action, gated on `agy` being present like the other CLI buttons, styled with the same cyan identity as the toolbar run button and run-mode dot.
+  - **`install.sh`** now detects `agy` (search paths mirroring `antigravity-cli-resolver.ts`), counts it as a satisfying AI CLI so an Antigravity-only box is not told it has none, and recommends it instead of Gemini in the install hints.
+
+  Documentation corrections where it had become factually wrong: `architecture-invariants.md` described `isExternalCliMode()` as opencode/codex/gemini when the code has included antigravity for some time, said "all three modes", and omitted `ANTIGRAVITY_*` from the env-prefix allowlist row; the `agentType` enum in `cron-guide.md`, `SessionMode` in `cron-discovery.md`, and `RemoteCommandMode` in `remote-sessions.md` were all stale.
+
+  Also updated both READMEs (five CLIs, Gemini marked enterprise-only), the `antigravity` npm keyword, and comment drift in eight places. Test coverage added for the new welcome button.
+
+  Antigravity stores its state under `~/.gemini/antigravity-cli/` rather than a `~/.antigravity` directory, so the existing `.gemini` Docker credential seed already covers it. That is now recorded in a code comment so no dead configuration gets added later.
+
+- b982c5d: Keep the brief Response Viewer output inside the same message card and Markdown wrapper used by the full conversation view, so opening the viewer without clicking More preserves the same readable formatting.
+
+## 1.11.1
+
+### Patch Changes
+
+- fix(history): Past Sessions data quality, and gate the phone run picker on CLI availability
+
+  **Past Sessions data quality (#215).** Three bugs in the transcript scanner behind
+  the Cmd+K Session Manager and the phone overview's PAST SESSIONS list:
+  - Automated/SDK-driven transcripts (CI review bots and other tooling, which Claude
+    Code stamps with a non-`cli` `entrypoint`) were listed alongside real interactive
+    sessions even though they were never resumable. They are now excluded. Detection
+    scans every entrypoint-bearing message rather than stopping at the first, so a
+    transcript that began under an older Claude Code build and only later picked up a
+    non-`cli` entrypoint is no longer wrongly hidden.
+  - A resumed session could show a same-directory sibling's preview text as its own.
+    The `workingDir` backfill in `mergeUnifiedSessions()` now only ever applies to rows
+    that have no history entry of their own, so it can no longer overwrite a row's real
+    content with another conversation's.
+  - Sessions restarted many times accumulated enough bookkeeping lines to push the real
+    first prompt past the scanner's 16KB head-read window, leaving a blank row. The read
+    is now two-tier: 16KB first, escalating to 128KB only when that was not enough, which
+    is both correct and cheaper than reading 128KB unconditionally (measured on a real
+    transcript tree: 36% fewer bytes read, roughly 17.5% faster than the unconditional
+    version). Also restores the tail-read fallback for a file whose head read failed
+    outright (for example `EMFILE` while scanning hundreds of files), which had been
+    silently dropping the session from history.
+
+  Follow-up hardening on top of the above: the automated-transcript exclusion now
+  blocklists the SDK entrypoint shape (`sdk`, `sdk-cli`, `sdk-py`) instead of allowlisting
+  the exact value `cli`. Because the check hides rows, an allowlist failed closed on any
+  value Claude Code has not shipped yet: a future rename of the interactive entrypoint,
+  or a second interactive host, would have blanked the entire Past Sessions list with
+  nothing in the UI to explain it. An unrecognized automated entrypoint now costs a few
+  noisy rows instead, which is the annoyance this filter set out to fix rather than a
+  broken feature.
+
+  **Phone overview run picker (#214).** The "C" logo home screen's Run picker listed all
+  six backends regardless of what was installed, so tapping an uninstalled one produced a
+  failed launch instead of the entry simply not being offered. It is now gated on
+  `isCliAvailable()` exactly like the desktop toolbar's run-mode dropdown (shell exempt,
+  since it has no external CLI dependency and keeps the menu from ever being empty). The
+  picker is a hardcoded duplicate of the toolbar menu rather than a shared render, which
+  is why it never picked up the earlier gating work; a test now asserts that every mode
+  the picker offers is gated, so a newly added backend cannot silently drift again.
+
+- 73315bc: fix(web): stop the Claude response viewer from following another session's conversation
+
+  The viewer re-derived a pane's live conversation by taking the newest
+  `~/.claude/history.jsonl` entry for the pane's cwd. A cwd is shared with every
+  other Codeman tab on it, with tabs long since closed, and with any plain
+  `claude` run in the user's own terminal, so the eye followed whichever of those
+  was typed into last — and the adoption was written back to the session, so the
+  mispin persisted. Entries are now credited to a pane only when they land within
+  10s of that pane's own Enter and no other pane on the cwd submitted closer, the
+  same last-submit correlation the Codex locator already uses.
+
+  That correlation also has to survive a restart. `start()` resets
+  `claudeSessionId` to the launch id even when re-attaching to a mux session whose
+  CLI has since moved on via `/clear`, so a recovered pane pointed the viewer at
+  its pre-`/clear` transcript — and with the anchor itself living only in memory,
+  nothing corrected it until the user happened to type again. `lastSubmitAt` is
+  now persisted in `SessionState` and restored on boot recovery, so the viewer
+  re-derives the live conversation on its first poll.
+
+## 1.11.0
+
+### Minor Changes
+
+- Two user-facing features since 1.10.0.
+
+  **Terminal: Ctrl+C copies the selection, interrupts when nothing is selected** (#211). Copying from the terminal previously worked only through the browser context menu: xterm turns Ctrl+C into 0x03 and cancels the keydown, so the muscle-memory copy failed silently and read as "no copy-paste at all". With a selection, Ctrl+C now copies it, shows the "Copied to clipboard" toast, clears the selection and sends nothing to the PTY; with no selection it falls through unchanged, so the interrupt is intact. Ctrl+Shift+C is an explicit copy chord that never interrupts. The shortcut is a normal registry entry (`copy-selection`), so it can be rebound or disabled in App Settings, and disabling it restores plain always-interrupt Ctrl+C. Copy goes through the Clipboard API with a hidden-textarea fallback, so it also works on plain-HTTP LAN installs.
+
+  **File Viewer: edit mode for text files** (#212). The file-preview overlay can now edit workspace text files in place, phone-first: `GET /api/sessions/:id/file-content?edit=1` reads for edit without the 500-line preview truncation (saving a truncated buffer would silently delete the rest) and returns a sha256 hash plus the detected EOL; `PUT /api/sessions/:id/file-content` saves. Edit-in-place only: there is no O_CREAT anywhere in the handler, so "never create, never delete" is structural. Confinement inherits the read path (realpath plus workspace boundary, ownership scoping) and adds sensitive-path and attachment-guard blocklists, a `.git/` subtree deny, and an extension allowlist (`svg` and `env` deliberately excluded). Optimistic concurrency is by content hash, so a file changed on disk mid-edit returns 409 with an overwrite option rather than clobbering. Writes are atomic (`wx` temp, fchmod, fsync, rename) which closes the validate-then-write TOCTOU window and cannot follow a pre-existing symlink. Binary and latin-1 content are refused via a NUL sniff plus a UTF-8 round-trip compare, and EOL is re-applied server-side so a textarea's LF normalization cannot turn a two-line edit of a CRLF file into a whole-file diff.
+
+## 1.10.0
+
+### Minor Changes
+
+- Codeman 1.10.0.
+
+  **Every surface that offers a CLI now checks the CLI is actually there** (#200, #201). The welcome-screen run buttons, the run-mode dropdown and the App Settings "Codex CLI" tab used to be shown unconditionally, so picking one on a box without the binary spawned a session that errored out immediately. All of them now gate on a single server-injected availability object covering Claude, OpenCode, Codex, Gemini, Antigravity and cloudflared, so nothing flickers in after paint and the dropdown costs no round trips to open. Shell is never gated, which is what keeps the menu non-empty on a box with nothing installed, and unknown availability reads as available so a stale page can never leave a working install with nothing to click. Adds `isClaudeAvailable()` and `GET /api/claude/status`, the one CLI that had no availability check despite being the default. The Cloudflare Tunnel welcome button and its scan-to-connect QR are gated on `cloudflared` rather than shown regardless.
+
+  **Shell and remote-SSH sessions now launch a real login shell** (#209, #210). Local shell tabs match what tmux itself does for a pane with no `default-command`, picking up the `/etc/profile` and `/etc/profile.d/*` entries a systemd `--user` service never sourced. On remote SSH, `claude`/`opencode`/`codex`/`gemini`/`agy` are routed through the remote user's interactive login shell, fixing agent CLIs that silently failed with "command not found" because ssh's remote-command execution sees only sshd's minimal default PATH and not the `~/.local/bin` or `~/.opencode/bin` entries where those CLIs actually live. Shell mode uses the remote user's real shell instead of hardcoded bash. The login flags are applied only to shells verified to accept them, so an exotic passwd entry (nushell, elvish, xonsh) cannot produce a dead pane on arrival.
+
+  **A crashed remote pane is kept for diagnosis** (#210), which is how the PATH failure above was found: it previously destroyed the pane, the window and the whole remote session on exit, tearing the local ssh attach down with it and leaving a flap loop with no evidence. Scoped to `remain-on-exit failed`, so a clean `exit` still tears the session down and only a non-zero exit strands anything, and applied last in the tmux command chain so a remote tmux older than 3.2 cannot drop the other session options with it.
+
+  **Resumed sessions under a hidden directory get the right working directory** (#202). Claude Code's project-key encoder maps both `/` and `.` to `-`, and the decoder could not reconstruct a dot-prefixed component, so every session under `~/.codeman` (or any project nested beneath any dotdir) silently resolved to bare `$HOME`. The wrong `workingDir` then propagated into `state.json` and everything trusting it: CLAUDE.md lookup, paste-image directory, subagent and image watchers. A same-named non-dot sibling could also produce a doubled-slash path that failed every later string comparison.
+
+  **Launching a session no longer wipes the terminal you are looking at** (#180). All six run modes route through the shared ownership helpers instead of clearing and writing into whatever session happened to be active, Antigravity included.
+
+  **Codex terminal animations are configurable** (#181), and the App Settings "Codex CLI" tab appears only where the `codex` binary resolves, since both settings on it are handed to `codex` at launch.
+
+## 1.9.9
+
+### Patch Changes
+
+- Two bug fixes.
+
+  **Plain shell sessions could not start when the server process had no `SHELL` (#208).** The tmux pane command for `mode: 'shell'` was the literal string `$SHELL`. That string is embedded in the `bash -c "..."` argument of the `respawn-pane` line, which is run through `/bin/sh -c`, so it was expanded by the _server_ process's shell against the _server_ process's environment rather than inside the pane. Containers and system-level systemd units do not set `SHELL`, so it expanded to nothing and the pane command ended in a dangling `&&`, giving `bash: -c: line 1: syntax error: unexpected end of file` and a pane that died instantly (status 2) while tmux session creation still reported success. The shell is now resolved in Node (`$SHELL`, then the passwd entry, then `/bin/bash`, `/bin/zsh`, `/bin/sh`), requiring an absolute path to an executable and skipping `nologin`-style stubs, then shell-quoted. Only local shell sessions were affected: agent CLI modes emit a real command, and Docker/remote-SSH cases already used a literal `exec bash -l`.
+
+  **A session name typed into the tab options could be silently dropped.** Two independent paths. In the Session Options modal, the Session Name input saves on blur while every autosave handler bails on a null `editingSessionId`, and `closeSessionOptions()` cleared that id before hiding the modal (hiding is what blurs the input), so the save always ran too late; Escape and backdrop-click lost the name with no PUT at all, and only the X button worked because mousedown blurs first. The focused modal field is now blurred before the id is cleared, which also covers the auto-compact prompt. Separately, the right-click inline rename could be destroyed mid-keystroke: the `_inlineRenameActive` guard was missing from `_renderSessionTabsImmediate()`, so a render queued just before the rename opened still rewrote the tab name's innerHTML, committing a truncated name or closing the rename outright. The debounced executor is now guarded too.
+
+## 1.9.8
+
+### Patch Changes
+
+- **Fixed: sessions failed to start on macOS with `Error: posix_spawnp failed.`** (issues #6 and #204)
+
+  `node-pty@1.1.0` publishes its macOS prebuilt helper as `prebuilds/darwin-<arch>/spawn-helper` with mode 0644, i.e. no execute bit. macOS launches every PTY through that helper, so a stock install failed on every session start. The bug is macOS-only: `spawn-helper` is a mac-only gyp target and node-pty ships no Linux prebuild, so Linux always compiles a correctly-permissioned helper from source.
+
+  The previous fix chmodded only `build/Release/spawn-helper`, which on macOS does not exist (the prebuild is used, so node-gyp never runs), and it derived that path from `require.resolve('node-pty')`, landing on `<pkg>/lib/build/Release/...`. It was a no-op on every platform.
+  - New `scripts/fix-node-pty.mjs` (also `npm run fix:node-pty`) chmods every `spawn-helper` it finds, in `build/Release`, `build/Debug` and each `prebuilds/*/`, then verifies the result by actually opening a PTY. A `require()` alone passes on a broken install, because the helper is only touched at spawn time.
+  - `postinstall` no longer force-rebuilds node-pty from source on Node 22+. That step needed Xcode command line tools, cost 30-120s on every install, and deleted the `prebuilds/` tree before compiling, so a Mac without a compiler was left with no working binary at all. A rebuild now happens only when the chmod plus spawn probe still fails, and the prebuilds tree is backed up and restored around it.
+  - New `spawnPtyWithHelperRepair()` (`src/utils/node-pty-repair.ts`) wraps every `pty.spawn()` in `session.ts`, so an install that is already broken repairs itself on the first failed spawn and retries in-process instead of showing a dead session. Unrelated spawn errors are rethrown untouched; a second failure carries the `npm run fix:node-pty` hint.
+  - `scripts/fix-node-pty.mjs` is now in the published `files` list, so global npm installs get the repair too.
+  - Direct-PTY Claude spawns use the resolved absolute binary path (new `getClaudeBinaryPath()`) instead of the bare name `claude`, so a CLI installed outside the server's PATH still launches.
+
+  Verified end to end on macOS 26.4 arm64: a stock `npm i` reproduces `posix_spawnp failed.`, and after the fix the same install spawns a PTY successfully with the prebuilds preserved.
+
+  **Added: phone home screen (session overview)**
+
+  Under 430px the "C" logo now opens a session overview (current sessions, past sessions, spaces) instead of the welcome overlay: on a small screen "which session needs me" beats "how do I start one". Rows resume a session in place, and "New session here" goes through the normal quick-start path so remote and Docker cases keep their routing. Per-device setting `mobileOverviewEnabled` (phones only, default ON) in App Settings. Tablet and desktop are unchanged.
+
+  **Added: guided Tailscale setup in `install.sh`**
+
+  The network-access prompt is now 3-way: Tailscale, LAN, or local-only. The Tailscale path binds loopback and walks through installing Tailscale, logging in, the operator grant, the tailnet HTTPS-certificates toggle, and `tailscale serve --bg <port>`, then verifies the result end to end with curl. That gives HTTPS on a real certificate with no app password and no `0.0.0.0` bind, which is also what PWA install and web push need. `install.sh tailscale` retrofits it onto an existing install, and `CODEMAN_TAILSCALE=1` presets the choice. Serve state is detected from `tailscale serve status --json`; the installer never runs `tailscale serve reset` and never touches serve mappings other than 443 to Codeman's port. README and `docs/security-architecture.md` updated to match.
+
+  **Docs**: replaced a real tailnet hostname with placeholders in `docs/web-tabs-fixes-plan.md`.
+
+  **xterm-zerolag-input**: npm description and keywords only, no code change.
+
+## 1.9.7
+
+### Patch Changes
+
+- Antigravity run mode, plus opt-in entrance animations.
+
+  **Antigravity CLI backend (#207).** Antigravity (`agy`) joins Claude Code, shell, OpenCode, Codex and Gemini as a sixth session backend, following the same pluggable-resolver pattern: `utils/antigravity-cli-resolver.ts` resolves the CLI and `GET /api/antigravity/status` reports availability and path. `ANTIGRAVITY_*` is added to the `ALLOWED_ENV_PREFIXES` allowlist so env overrides stay CLI-scoped rather than blanket-forwarded. Like the other external CLIs it requires tmux with no direct PTY fallback, because secrets are injected through socket-scoped `tmux setenv` and never on the spawn command line. The UI gains a Run-dropdown entry, an agent-type option, an `ag` tab badge and toolbar colours; `runAntigravity()` routes remote and docker cases through `POST /api/quick-start` and skips the local status probe for them.
+
+  **Entrance animations (opt-in, OFF by default).** Optional animations for the four things that appear when work starts: session tabs, the terminal pane a session's CLI runs in, floating agent windows, and the connection lines tying a window back to its parent tab. Defaults are the `legacy` theme, so an untouched install behaves exactly as before and every hook short-circuits on its first line. Choose a look in App Settings > Appearance > Entrance Animations (per-device, stored in localStorage rather than the settings payload); `?animlab=1` opens a per-surface picker with a live preview that fakes tabs, a pane, a window and a line so styles can be compared without spawning sessions.
+
+  Three implementation notes worth knowing if you touch this: tabs and connection lines are destroyed mid-animation on every re-render (`_fullRenderSessionTabs()` replaces the strip's innerHTML, `_updateConnectionLinesImmediate()` clears the SVG), so both are tracked by id and re-applied to the fresh element with a negative `animation-delay` that resumes rather than restarts them; terminal-pane styles animate transform, opacity and clip-path only, because xterm's FitAddon derives rows and columns from the untransformed layout box and animating width or height there would resize the PTY; and window styles that transform also move the rect their connection line aims at, which is why the `beam` style animates opacity and filter only.
+
+  Also fixes an agent window spawning hidden (its agent belongs to a background tab): being `display:none` it never ran its animation, so `animationend` never fired and the entrance class plus its inline custom property stuck to the window permanently. Hidden windows now skip the entrance entirely.
+
+## 1.9.6
+
+### Patch Changes
+
+- Two fixes from community PRs (thanks @Lint111):
+  - fix(transcripts): complete tools from user-entry results (#177). Claude transcripts record tool requests in assistant entries but commonly carry their results in user-role entries; the transcript watcher only completed tools from the older assistant-entry path, so Codeman could keep showing a tool as running after it had finished. The watcher now recognizes `tool_result` blocks in user entries, ends the active tool state, and emits `transcript:tool_end` with the correct tool name and error status. Watcher tests also moved from fixed sleeps to condition-based `vi.waitFor` assertions.
+  - fix(notifications): quiet lifecycle hook noise (#178). Notification preferences move to schema version 5: the drawer-only "Response complete" (stop) default is now off, and the migration disables only the legacy drawer-only shape, preserving any explicit browser, audio, or push delivery the user opted into. Teammate-idle and task-completed hooks now map to the existing opt-in subagent categories instead of the broadly enabled idle/stop alerts, so normal agent activity no longer floods the drawer. Local and server-hydrated preferences are normalized through the same migration path (server hydration used to revive the retired default on fresh browsers), and the notification storage key now uses the stable handheld identity so an unfolded foldable keeps its mobile defaults and storage key (tablets and desktops unaffected).
+
+## 1.9.5
+
+### Patch Changes
+
+- Background-Bash rewake hook, hooks self-heal that preserves user hooks, and test-harness isolation.
+  - New `PostToolUse(Bash)` hook (PR #176): a self-contained `node -e` helper watches the session transcript for a background command's completion notification and uses Claude Code's `asyncRewake` to wake an idle agent (exit code 2), without injecting terminal input that could submit a user's draft. Works on Claude Code 2.1.207+; older CLIs strip the fields harmlessly.
+  - Hooks self-heal (`refreshStaleHookSecret` renamed to `refreshStaleCodemanHooks`) now replaces only Codeman-owned handlers, preserving user events, matchers, and sibling handlers in mixed configurations; `writeHooksConfig` merges instead of clobbering the hooks key at case creation (PR #176).
+  - Rewake helper hardening: self-terminates on its own 6h deadline and when orphaned; the marker is versioned (V2) with a version-agnostic ownership prefix so future script updates replace older handlers instead of duplicating them.
+  - Hook timeout units fixed: the hook `timeout` field is seconds (the CLI multiplies by 1000), so `HOOK_TIMEOUT_MS = 10000` gave curl hooks a ~2.8-hour effective timeout; now `HOOK_TIMEOUT_SECONDS = 10`.
+  - Test-harness isolation (PR #175): every test file gets a temporary `HOME`/`USERPROFILE` so tests cannot touch real Codeman state or delete real case directories, and `Session` attaches a raw-mode echo PTY instead of a real tmux client under Vitest. Fixes the quick-start suite deleting the real `~/codeman-cases/testcase`.
+  - CI stability: drain console-log rpc forwards before worker teardown (fixes a run-failing `EnvironmentTeardownError` with all tests passing); `test/webview-proxy.test.ts` no longer accidentally runs under the jsdom environment via a directive named in a comment.
+  - Release workflow pins the GitHub "Latest" badge to the Codeman release.
+
+## 1.9.4
+
+### Patch Changes
+
+- Fix a latent bug where a partial settings PUT silently reset live service state, and trim the `xterm-zerolag-input` README callout.
+  - **`PUT /api/settings` no longer resets watchers on a partial body.** The three `toggleService` calls (subagent watcher, workflow-run watcher, image watcher) read the raw request body with `??` defaults, so every key a caller omitted was treated as "apply the default". A body of just `{statusLineTelemetry:true}` would START the subagent watcher and STOP the workflow and image watchers, undoing the persisted config. They now resolve from `merged` (persisted settings + incoming), the same convention the `tmuxHistoryLimit` branch in that handler already used, so any PUT reconciles services to the effective stored state. Nothing triggered this in practice because every shipped client sends a full settings payload rebuilt from the DOM, but it was a trap for the next partial-update caller.
+  - **Regression test**: `test/routes/system-routes-settings-partial-put.test.ts` (4 cases) pins both directions, omitted keys preserve state and explicit keys still take effect. Verified to fail against the pre-fix handler.
+  - **CLAUDE.md** records the rule under "Adding Features → App setting": anything acting on a setting in that handler must resolve from `merged`, never the request body.
+  - **`xterm-zerolag-input` README**: removed the links line (getcodeman.com / install one-liner / star link) from the Codeman callout above the demo GIF. The callout keeps its links in the heading and body.
+
+## 1.9.3
+
+### Patch Changes
+
+- Plan-usage chip now defaults ON on desktop, plus the reworked `xterm-zerolag-input` README.
+  - **Plan-usage chip defaults ON (desktop).** The `showPlanUsageLimits` chip (live 5-hour and weekly plan usage from the Claude statusline) used to be opt-in and default OFF, so most users never saw it. Desktop now defaults ON; handhelds still default OFF so the phone header stays minimal and the `mobile-header-buttons-policy` guard keeps passing. Devices with an explicitly stored preference keep whatever they chose, so nobody's OFF gets overridden.
+  - **One resolver behind the chip.** Added `planUsageChipEnabled()` in settings-ui.js and routed all three call sites through it: the App Settings checkbox, the chip's visibility, and the create-time `statusLineTelemetry` flag in session-ui.js. Those three had independent `?? false` / `=== true` defaults, and a chip revealed without the telemetry flag renders `—` forever, so a default flip on one site alone would have shipped a permanently empty chip.
+  - **Cron button comment corrected.** The App Settings comment claimed "Cron button defaults ON" while the code, the template (`btn-cron--hidden`) and the CSS all default it OFF. Verified against a fresh browser profile: the button is hidden and its checkbox unchecked out of the box. Comment now matches, and states why the two halves stay consistent.
+  - **Docs.** CLAUDE.md, `docs/architecture-invariants.md` and `docs/usage-limits-display-plan.md` updated for the new default and the single-resolver rule; the stale `styles.css` comment claiming the server strips the chip's hidden class at render was corrected (display is per-device, so the client reveals it).
+  - **`xterm-zerolag-input` README rework** (0.1.5 shipped the content; this republishes with the graphic and promo changes): replaced the misaligned 8-line keystroke-flow diagram with a two-line stock-vs-zerolag contrast, added a Codeman callout above the demo GIF with links to getcodeman.com and the repo, and rewrote the Origin section so it argues the extraction story instead of repeating the promo.
+
+## 1.9.2
+
+### Patch Changes
+
+- Rewrite the `xterm-zerolag-input` package README as a value-first document and correct the drift that had accumulated against the source.
+  - Added the side-by-side phone demo GIF (`docs/images/zerolag-demo-20260728.gif`) as the hero image, referenced by absolute raw URL so it renders on npmjs.com as well as GitHub. The two-phone comparison shows 0ms local echo next to a 600ms-2.7s server echo on the same session.
+  - New "Why this one" comparison table, an explicit list of target use cases (SSH web clients, cloud IDEs, mobile terminals, container consoles), and a bundle-size badge (6.1 kB gzipped, measured from the ESM build).
+  - Corrected the test-count badge from 78 to the actual 175 tests across 5 files, in both the package README and the Published Packages section of the root README.
+  - Removed the stale "Unicode/emoji rendered at single-cell width" limitation. CJK, fullwidth forms and emoji have had double-width rendering and visual-column positioning since the wide-character fix; the honest remaining caveat (per-code-point width summing over-counts ZWJ grapheme clusters) replaces it.
+  - Documented the previously undocumented public `setPrompt()` method for switching prompt strategies at runtime, and the new "Wide characters (CJK, emoji)" integration section covering the optional `Unicode11Addon` path and the built-in range-table fallback.
+  - Documented `backgroundColor: 'transparent'`, corrected the `foregroundColor` default, and updated the grid-alignment math to reflect visual-column positioning rather than character index.
+
+  No source changes, docs only.
+
+## 1.9.1
+
+### Patch Changes
+
+- Narrow the Run dropdown, and close the last two gaps in web-tab asset rewriting.
+
+  **The Run dropdown was pinned at its full width.** It capped at 300px, and the recent-session rows wanted 326px, so it always rendered at the cap and reached further across the terminal than it needed to. Now 250px, chosen as the width at which a `~/<dir>/<repo>` + timestamp row still fits whole, since identifying a session to resume is what that list is for. Three fixes were needed to make the narrower menu degrade instead of clip: the saved-URL label now has its own element, because `text-overflow` on the row button did nothing (a bare text node inside a flex container becomes an anonymous flex item that ellipsis cannot reach); `.hist-dir` got `min-width: 0`, without which a flex item refuses to shrink below its own text and pushes the date out of the box; and history rows are held to the container width, because the list's `overflow-y: auto` implicitly makes `overflow-x: auto` and let each row size to its own content and scroll sideways. Phone and tablet widths are unchanged, being set separately in `mobile.css`.
+
+  **A dashboard's own `/api/...` assets are relayed again.** The `Referer`-keyed 404 fallback, which rescues a root-absolute asset that no rewrite layer could reach, refused everything under `/api` outright. Dashboards commonly serve their assets from exactly that namespace, so those requests had no rescue at all. The refusal is now precise: the relay runs before the API-shaped 404, and the auth exemption refuses only paths that resolve to a REAL Codeman route, with `/ws/` and `/q/` still refused by prefix.
+
+  Two findings shaped that fence, both from probing Fastify rather than reading it. `hasRoute()` matches the registered PATTERN literally, so `/api/sessions/abc` reports no match against a registered `/api/sessions/:id` and would have granted an unauthenticated exemption on a live session-scoped route; `findRoute()` performs the real lookup and is what the fence uses. And `@fastify/static` is mounted at `/`, so it registers a root catch-all matching every path, which has to count as "no real route" or the fence would refuse every referer-form request and break the rescue that already worked. A root catch-all is distinguishable because it is the only route whose wildcard param comes back equal to the whole request path. The fence fails closed, and both edges are pinned in `test/webview-auth-exemption.test.ts`.
+
+  **`url()` inside runtime CSS is rewritten.** Measuring the fallback against a purpose-built dashboard showed one sink no relay can reach: a `<style>` element built by page script has no URL of its own, so the browser sends an EMPTY `Referer` with the image request it triggers. The injected URL shim now rewrites root-absolute `url()` in `<style>` blocks, both as markup and when a `<style>` node is inserted. Verified in Chromium: a stylesheet-only `/api/hero.png` and a runtime `<style>` `/api/late.png` both load, where both previously failed. The remaining known gap is self-navigation via `location.href`, which cannot be patched because `Location.href` is unforgeable.
+
+## 1.9.0
+
+### Minor Changes
+
+- 2667150: feat(mobile): browse and insert local file and folder paths
+
+  Add a root-confined filesystem picker to Link Existing and the extended mobile
+  keyboard bar. Selected paths remain editable at the active prompt, supported
+  images/documents/text files open in a safe inline preview, and a new one-tap
+  action clears only the current unsent input without invoking `/clear`.
+
+### Patch Changes
+
+- 3cff98f: Fix two multi-user scoping holes in the new filesystem path picker. `GET /api/filesystem/browse` and `GET /api/filesystem/preview` accept an optional `sessionId` that contributes the session's working directory as a browse root, but they resolved it straight off the session map without an ownership check, unlike the nine other session-scoped handlers in the same route file. A non-admin could therefore pin another user's working directory as a root simply by passing their session id, then list and preview files under it. Both endpoints now run `canAccessOwned` and report 404, which also avoids confirming that a session id exists.
+
+  Separately, `Home` and `CASES_DIR` were unconditional browse roots for every caller. Per-user spaces live at `<USER_SPACES_DIR>/<username>`, which is inside `homedir()`, so the `Home` root alone exposed every other user's workspace to any authenticated user. In multi-user mode a non-admin now gets only their own space plus anything explicitly listed in `CODEMAN_FILE_PICKER_ROOTS`; `/mnt/d` is no longer offered by default, since a broad host mount should be an explicit operator decision in a multi-user deployment. Admins keep the host-wide roots, and single-user mode is unchanged.
+
+  Both holes are regression-guarded in `test/routes/file-routes.test.ts`, verified to fail against the previous code. Multi-user mode is opt-in and off by default, so single-user installs were never affected.
+
+- Web tabs: delete saved URLs from the Run dropdown, and fix images in proxied dashboards.
+
+  **Saved URLs are now manageable from the dropdown.** Each row under "Web / URL" gains a gear and an `x`, so a URL can be edited or deleted without first opening it as a tab. Previously the only delete path ran through the gear on an open tab, which was a dead end for a URL you no longer wanted open at all. Both controls stay permanently visible rather than hover-revealed, because the same menu is used on touch, and they get a larger hit box there. Deleting leaves the dropdown open on the remaining rows, and deleting the dashboard that is currently open also closes its tab and unmounts its frame.
+
+  **Runtime-injected images no longer 404.** A dashboard that renders its own markup from script (`card.innerHTML = '<img src="/api/hero?slug=x">'`, `img.src = '/api/slide'`) escaped every rewrite layer at once: `<base href>` never applies to a root-absolute URL, the server-side attribute rewrite only ever sees the initial document, and `runtimeUrlShim()` patched only `fetch`, `XMLHttpRequest`, `WebSocket` and `EventSource`. Those requests landed on Codeman's own root and 404'd, with a symptom that reads as an upstream fault: the dashboard's data loaded while every image stayed broken.
+
+  The shim now also covers the DOM URL sinks, so the request is never emitted in the first place and neither the `/api` fence in the 404 fallback nor the one in the auth middleware had to move. It wraps `innerHTML`, `outerHTML`, `insertAdjacentHTML` (including on `ShadowRoot`), `setAttribute`/`setAttributeNS`, and the `src`/`srcset`/`href`/`poster`/`data`/`action` property setters on img, source, media, video poster, script, iframe, embed, track, link, anchor, area, object and form, with a `MutationObserver` as a last net for sinks not patched above. Every rewrite routes through the same idempotent helper, which matters because unlike the server-side rewrite this one sees markup that may already be proxied, and a page re-injecting its own `outerHTML` would otherwise double-prefix. Everything is defensively guarded and marked so a double injection cannot wrap an already-wrapped setter.
+
+  Measured against a real dashboard: 693 image elements, 0 of them under the proxy prefix and 0 of 23 in-viewport images decoded before, 693 and 23 of 23 after. Covered by a new jsdom suite over the shim's DOM half and a new frontend suite over the dropdown rows. Known remaining gaps are documented in `docs/web-tabs.md`: a root-absolute `url()` inside a stylesheet injected at runtime, and self-navigation via `location.href`, which cannot be patched because `Location.href` is unforgeable.
+
+  Also in this release: a value-first README overhaul pointing at getcodeman.com, and the QR-auth distribution test now uses a chi-square check instead of a max-deviation threshold that failed on random variance.
+
+- bca56b4: Normalize Claude conversations in the response viewer. A Claude transcript is an append-only event log, so one logical exchange spans many JSONL rows: tool-result rows, meta/image/skill rows, compact summaries, task and team notifications, sidechains, replayed assistant snapshots, and multi-block assistant output. The viewer rendered a card per row, which produced duplicate and truncated cards that read as lost responses. Cards are now built at real human-turn boundaries, replayed assistant snapshots are deduplicated, and sidechain rows (which belong to subagents, not the main conversation) no longer leak in. An identical prompt that legitimately recurs after an assistant reply is still kept as its own turn.
+
+  Measured over 40 real transcripts: 3108 cards became 621, duplicate cards dropped from 74 to 8 (all of them genuinely repeated turns), no assistant text was lost, and the non-`context=full` last-response text was byte-identical on every file.
+
+  Also rebinds recovered sessions to their transcript. `reconcileSessions()` can recover a lost mux session as a `restored-<uuid8>` placeholder with a stale working directory, which made transcript lookup by cwd find nothing. The placeholder still carries the first eight characters of the conversation UUID, so the viewer now rebinds to the matching top-level transcript when exactly one candidate matches.
+
+## 1.8.3
+
+### Patch Changes
+
+- 8c089a4: Add four light UI and terminal skins: Paper Gray, Solarized Light, Catppuccin Latte, and Rosé Pine Dawn. The Skin picker now groups Light and Dark options, and each light skin ships a matching xterm ANSI palette plus `color-scheme: light` so native selects, date pickers and scrollbars stop rendering as dark OS widgets on a light page. Terminals set `minimumContrastRatio: 4.5` under a light skin (main terminal and teammate terminals both), which keeps CLI output that assumes a dark background readable, and `applyTerminalSkin()` now refreshes the zero-lag input overlay so typed-but-unflushed text does not keep the previous theme's colors.
+
+  Elevated surfaces (modals, command palette, dropdowns, subagent and ultracode windows, file preview, attachment tray, mobile sheets) now resolve through shared `--floating-bg` / `--control-*` / `--banner-bg-*` / `--modal-backdrop` / `--elevated-shadow` tokens instead of hardcoded near-black rgba, so they follow whichever skin is active. On the Daylight skins this lifts modals slightly off the page background; OG Codeman pins its own near-black value to keep that palette neutral.
+
+  Also defines twelve CSS compatibility aliases (`--bg-primary`, `--bg-secondary`, `--bg-tertiary`, `--text-primary`, `--text-secondary`, `--border-color`, `--accent-color`, `--success`, `--error`, `--danger`, `--font-mono`, `--shadow-lg`) that panels and overlays already referenced in about 79 places but which were never actually declared, so those rules silently resolved to nothing. Status badges and accent-tinted pills (search filter chips and result badges, session tab mode pills, respawn state, Ralph priority and circuit-breaker badges, tunnel and voice status, mobile case picker) no longer keep their pale light-on-dark ink under a light skin, where it measured 1.0 to 1.9:1 and made the search filter chips invisible.
+
+  New static regression `test/skin-themes.test.ts` guards the four-way parity between the CSS token block, the xterm palette, the pre-paint allowlist and the Settings picker.
+
+## 1.8.2
+
+### Patch Changes
+
+- Web tabs: open dashboard URLs as tabs beside agent sessions, plus terminal link fixes.
+
+  **Web tabs.** The Run dropdown gains a "Web / URL" section. A saved URL renders as a tab in the same strip as Claude/Codex/Gemini sessions, with the same Alt+1-9 numbering, an icon picker, and per-device tab order. Frames stay mounted while hidden (LRU-bounded), so switching tabs never reloads a dashboard.
+
+  Dashboards are proxied through Codeman's own origin, because a direct iframe fails three ways at once: an HTTPS Codeman cannot embed a plain-HTTP target (mixed content, with no override at all on iOS Safari), many dashboards send `X-Frame-Options: DENY`, and Codeman's own `default-src 'self'` CSP blocks cross-origin frames. Proxying dissolves all three and leaves the production CSP unchanged. The fetch happens server-side, so a tailnet-only or localhost-only dashboard is reachable from any device that can reach Codeman.
+
+  The proxy is not an API surface: it authenticates on a 192-bit capability in the path (memory-only, rolling TTL, bound to the minting user, revoked on edit or delete) and is exempt from the cookie and Origin checks, because a sandboxed iframe is opaque-origin and sends neither. The Host allowlist is never bypassed. Iframes omit `allow-same-origin` unless a URL is explicitly marked trusted, and `Authorization` plus the session cookie are stripped upstream in both modes so `CODEMAN_PASSWORD` cannot leak into a dashboard. Includes an HTTP and WebSocket proxy, redirect/cookie/`<base>` rewriting, a runtime URL shim for requests built by dashboard JavaScript, and CORS handling for the opaque-origin frame. New endpoints under `/api/webviews`, storage in `~/.codeman/webviews.json`, user guide in `docs/web-tabs.md`.
+
+  **Terminal links no longer truncate.** Three separate cuts, each producing a link that opened the wrong target or none at all:
+  - A single `&` ended the match, so every query string was cut. A WordPress edit link resolved to `?post=1479` and Claude Code's own `/login` URL was unusable. `&` is now part of a URL while `&&` remains a boundary.
+  - Links wider than the terminal were cut at the row boundary. The link provider now stitches continuation rows into one logical line and maps offsets back across rows. Handles both soft wraps (emulator, `isWrapped`) and hard wraps (a program wrapping its own output and emitting a newline, as Ink does), the latter being why the `/login` URL grew longer as the window was widened.
+  - Image and PDF paths were not matched at all, so pasted-screenshot paths rendered as plain text. They now link and open the file preview, which renders images inline.
+
+  **Also fixes** a pre-existing bug where `.toolbar`'s `backdrop-filter` created a stacking context that trapped the Run menu's z-index, letting the welcome overlay cover it: with no session open, every item in that menu (Claude Code included) was unclickable.
+
+## 1.8.1
+
+### Patch Changes
+
+- Mobile toolbar: a dedicated Enter button, and Shell moves into the Run dropdown.
+
+  Submitting is a constant need on a touch keyboard, so on phones (≤430px) the toolbar slot that held "Shell" now holds a dark blue **Enter** button. Starting a shell, the far rarer action, moves into the expandable Run dropdown as `Terminal / Shell` (the Run button then reads "Run SH"). Desktop and tablet are unchanged: the green Run Shell button stays exactly where it was.
+
+  Enter is replayed through the terminal's own input path rather than posted to the input API. This matters because local echo is on by default on touch devices: the characters you type are buffered client-side and have not yet reached the PTY, so sending a bare carriage return would submit an empty line and leave your text stranded on screen. Replaying the keypress flushes the buffered text first, then submits.
+
+  Installer: re-runs and updates now preserve the existing network binding instead of silently reverting it, so upgrading no longer changes how the dashboard is reachable.
+
+  Default desktop header is cleaner: the file viewer is shown by default and the plan-usage chip is unchanged, while the token-count chip and lifecycle-log button now default off. Stored preferences are still honored.
+
+  Docs and repo housekeeping: fresh phone screenshots and a new hero GIF in both READMEs, contributor and total-commit badges, and a much shorter repo root. `SECURITY.md` moved to `.github/` (GitHub resolves it there, so the Security policy tab is unaffected), `SPEEDRUN.md` to `docs/`, the knip config to `config/`, and Prettier's config into the `"prettier"` key of `package.json`. `CLAUDE.md` was split so the always-loaded guidance is roughly half its former size, with the deep implementation detail preserved verbatim in `docs/architecture-invariants.md`.
+
+## 1.8.0
+
+### Minor Changes
+
+- Installer: choose your network binding, with LAN access as the new guided default.
+
+  The install script now asks at the end of setup how the dashboard should be reachable:
+  1. Any device on your network (0.0.0.0), the default. The installer prompts for a dashboard password (hidden input, confirmed twice); declining a password requires an explicit confirmation and the install ends with a prominent warning explaining the exposure.
+  2. This machine only (127.0.0.1), the safer option for tunnel/Tailscale setups.
+
+  The choice is wired into the generated systemd unit and launchd plist (values escaped for each format), the run-now launch path, and the printed URLs, which now include the detected LAN IP for instant phone access. Non-interactive installs keep the safe loopback default unless CODEMAN_HOST is preset, and the server binary's own default binding (127.0.0.1) is unchanged, so npm and manual installs behave exactly as before. New installer env presets: CODEMAN_HOST and CODEMAN_PASSWORD skip the prompts for automation.
+
+## 1.7.1
+
+### Patch Changes
+
+- Mobile and UI polish plus docs refresh.
+  - Mobile: the header brand collapses to a single "C" home button on phones (<430px), freeing header space for session tabs while keeping the same tap target. The compact letter lives in its own span so i18n custom branding keeps rewriting only the full wordmark.
+  - UI fix: the absolutely-centered toolbar voice button no longer overlaps the case picker's chevron and "+" button. Below ~1500px (or with long case names widening the left toolbar group) it now falls back into normal flex flow where overlap is impossible; wide viewports keep the centered layout.
+  - Docs: README gains a hero pitch block with deep links, npm version + GitHub stars badges, and a star CTA; CLAUDE.md core-files table synced (Infra docker modules, app.js line count); blog article images added under docs/images/blog/.
+
+## 1.7.0
+
+### Minor Changes
+
+- Community release (thanks @shenlvkang-collab for all four PRs) plus documentation fixes.
+  - fix(mobile): per-device settings now key off a stable handheld classification (`MobileDetection.isHandheldDevice()`: touch plus UA form-factor tokens, with User-Agent Client Hints fallback) instead of the instantaneous viewport width, so an Android foldable that unfolds past the desktop breakpoint keeps `codeman-app-settings-mobile` and opt-ins such as the Response Viewer and Extended Keyboard Bar. Responsive layout stays width-driven. Adds an OPPO Find N5 (unfolded) device profile and a fold/unfold/reload Playwright regression test (mobile suite now 136 devices). (#162)
+  - fix(paths): `SAFE_PATH_PATTERN` now accepts Unicode letters and numbers (`\p{L}\p{N}` with the `u` flag), so working directories like `/mnt/d/AI/中文项目` validate in Create Session, Quick Run, and Scheduled Run. All shell-metacharacter, traversal, and absolute-path protections are unchanged. (#163)
+  - fix(ui): newly created run sessions render their tab immediately instead of waiting for the `session:created` SSE event (idempotent upsert from the POST response, with a `GET /api/sessions/:id` fallback for quick-start modes), and the Run button holds an in-flight lock (min 500 ms) so a double click cannot create duplicate sessions. (#164)
+  - feat(ui): the synced custom display name and per-device English/Simplified Chinese UI language are described in their own entry (#165); on top of that PR, `renderIndexHtml` no longer recomputes `windowTitle` on solo-session renders, so a detached window cannot reset the push-notification `hostTitle` prefix to the default name.
+  - docs: corrected the `sse-events.ts` fileoverview breakdown (148 event constants, was stale at 120; per-category counts refreshed, including Cron, Docker, Remote auto-reconnect, and Multi-user) and the CLAUDE.md SSE registry count; READMEs synced with the 1.6.2 installer behavior.
+
+### Patch Changes
+
+- 8d9fc41: Add a synced custom display name and a per-device English/Simplified Chinese browser UI language picker under App Settings → Display.
+
+## 1.6.2
+
+### Patch Changes
+
+- Installer (install.sh) reliability and safety overhaul, prompted by a review of the Linux flow:
+  - Install-completion marker (`.install-complete`): a bare re-run only takes the quiet update path when a previous install actually finished. Previously, a first install that failed during npm install/build (or was interrupted) left `.git` behind, so the retry silently became an "update" and the user never got the launch menu, the `codeman`/`tmux-chooser` symlinks, the PATH entry, or the `sc` alias. The marker is refreshed by updates and cleared by uninstall when the app dir is kept; added to .gitignore for end-user clones.
+  - `update` no longer runs an unconditional `git reset --hard` over local changes: interactive runs are asked to stash (declining keeps everything and skips the update), headless runs auto-stash with a dated message (same policy as scripts/self-update.sh).
+  - Service setup is verified instead of asserted: after starting codeman-web, the installer polls `systemctl --user is-active` (up to 6s) and only then prints "Codeman is running now!"; failures print an honest warning plus status/journalctl hints. Uses `restart` instead of `start` so re-running the installer over an already-running service actually loads the new build. A missing user D-Bus session (e.g. bare `ssh host 'curl | bash'`) is detected up front with copy-paste recovery commands instead of dying mid-setup via `set -e`. macOS gets the equivalent `launchctl list` verification, and the update path verifies its service restart too. The Cloudflare tunnel-service offer is skipped when service setup failed.
+  - Headless consent guard: with no interactive terminal AND no explicit `CODEMAN_NONINTERACTIVE=1`, the installer now refuses (with instructions) to run sudo package installs (git/node/tmux) or third-party `curl | bash` AI CLI installers, instead of silently taking the default-yes prompts. Explicit `CODEMAN_NONINTERACTIVE=1` keeps the previous full-auto behavior for CI/automation.
+  - AI CLI gate now recognizes Codex and Gemini (search paths mirrored from the CLI resolvers), so a box with only Codex or Gemini installed is no longer forced to install Claude Code/OpenCode. The install menu gains a "Skip" option (with npm install hints for Codex/Gemini), and the final reminder lists all four CLIs.
+
+  Docs: CLAUDE.md documents `src/remote-reconnect.ts` (pure COD-108 auto-reconnect backoff/eligibility logic) in the Infra table and the remote-sessions pattern.
+
+## 1.6.1
+
+### Patch Changes
+
+- **Admin Panel for multi-user mode.** Admins in multi-user mode now get a prominent Admin Panel button at the top of the page (header, admin-only; the template ships it hidden and `admin-ui.js` reveals it after identity boot; hidden on phones per the mobile header policy, where user management stays reachable via App Settings > Users). It opens a full Admin Panel modal: a users table with role, enabled/disabled status, bypass-permissions grant, live sessions, active logins, case count, and last login; per-user actions for Promote/Demote, Enable/Disable, Grant/Revoke bypass, Reset password (copyable one-time password), Force logout, and Delete (with an optional "also delete their files" step); and a proper add-user form (role, optional password, bypass checkbox) replacing the old prompt() flow. Each user's cases open in a drawer listing their case folders (modified date, live-session badge) with per-folder delete. Two new admin endpoints back this: `GET /api/admin/users/:username/cases` and `DELETE /api/admin/users/:username/cases/:caseName`, guarded like `deleteUserSpace` (symlinks refused, realpath confined to the user's space, folders in use by a live session refused with 409, audit-logged). The panel and the App Settings Users tab live-refresh on the SSE `admin:usersChanged` event (now wired in app.js). New coverage in `test/admin-routes.test.ts` (list/delete, traversal + symlink refusal, non-admin 403) and `test/admin-ui.test.ts` (button reveal gating, panel render, case drawer); verified end to end against a live multi-user instance with curl and Playwright.
+
+  **Also in this release:** README/docs synced with 1.6.0 (remote SSH cases, session manager, permissions) and fixed installer prompts when run via `curl | bash`.
+
+  **Recap of the recent feature line, for readers catching up:**
+  - **Multi-user mode (shipped 1.5.0, opt-in `--multiuser` / `CODEMAN_MULTIUSER=1`).** Named users with scrypt-hashed passwords, per-user case spaces under `~/codeman-users/<name>/cases`, and full ownership scoping of sessions, cases, cron jobs, scheduled runs, search, file previews, and SSE/WS streams. Non-admin users default to Claude's classifier-guarded `--permission-mode auto`; shell mode, cron `launchCommand`, and skip-permissions bypass switches require the per-user `canBypassPermissions` grant (now toggleable from the Admin Panel). Admin API with one-time passwords, last-admin invariants, and an append-only audit log; self-service `/api/me` password change; `codeman users add|passwd|list|rm` CLI. Off by default is byte-identical to single-user. Note: multi-user separates workspaces for a trusted team; it is not a security boundary (all sessions share the host OS account), so pair it with Docker cases for real isolation.
+  - **Docker cases (shipped 1.4.0/1.4.1).** A case can run inside an isolated per-case container (any of the five CLI backends), with one-click "Run in Docker" quick-create, durable in-container tmux that survives Codeman restarts and resumes conversations after container stops, hardened container creation (cap-drop ALL, no-new-privileges, non-root, memory/pid limits, never privileged, never the docker socket), commit-safe seeded credentials, config-drift detection, GPU passthrough, and portable export/import bundles to move a whole case between machines.
+  - **1.6.0 highlights.** Remote SSH cases with durable remote tmux (survives SSH drops, auto-reconnect, shared multi-client attach, discover + attach with detach-not-kill); the Cmd+K session palette and unified Session Manager with pinning, cross-device tab order, and first/last prompt search; full-scrollback replay; and the multi-user permission downgrade now threading through to remote launch/attach.

+**Codeman** is a self-hosted mission control for AI coding agents. It spawns Claude Code, OpenCode, Codex, Antigravity, or Gemini CLI inside persistent tmux sessions, streams the real terminal to any browser, and keeps agents productive after you walk away: it re-prompts on idle, resumes when a usage limit resets, runs scheduled jobs, and shows every background agent working in real time.

+This installs Node.js and tmux if missing, clones Codeman to `~/.codeman/app`, and builds it. A few things worth knowing:
 
-You'll need at least one AI coding CLI installed — [Claude Code](https://docs.anthropic.com/en/docs/claude-code), [OpenCode](https://opencode.ai), [Codex](https://developers.openai.com/codex/cli), or [Gemini CLI](https://github.com/google-gemini/gemini-cli) (any combination works). After install:
+- **It asks first.** Every system change (package installs, AI CLI download) is prompted, and a menu at the end lets you choose: run Codeman in this terminal, install it as a background service (systemd/launchd, auto-start on boot), or don't start yet. Nothing runs in the background unless you pick it.
+- **Network or local-only, your choice.** The installer asks whether the dashboard should be reachable from other devices on your network (`0.0.0.0`, the default, with a strongly recommended password prompt) or from this machine only (`127.0.0.1`, safest). Skipping the password on a network bind requires an explicit confirmation and ends with a loud warning. A bare `codeman web` started by hand still defaults to loopback.
+- **Re-run to update.** The same one-liner updates a finished install in place: local changes in `~/.codeman/app` are stashed (never discarded), and a running service is restarted and verified. If a first install was interrupted, re-running resumes the full setup instead. `install.sh update` and `install.sh uninstall` also exist.
+- **CI / headless:** without a terminal attached, steps that would change your system abort with instructions instead of running silently. Set `CODEMAN_NONINTERACTIVE=1` to approve them for automation.
+
+You'll need at least one AI coding CLI installed — [Claude Code](https://docs.anthropic.com/en/docs/claude-code), [OpenCode](https://opencode.ai), [Codex](https://developers.openai.com/codex/cli), [Antigravity](https://antigravity.google), or [Gemini CLI](https://github.com/google-gemini/gemini-cli) (any combination works; Gemini CLI is enterprise-only since Google's consumer cutover, and Antigravity is its successor). The installer detects whichever of the five is present; if none is found, it offers to install Claude Code or OpenCode, or you can skip and install one yourself later. After install:
 
 ```bash
 codeman web
 # Open http://localhost:3000 and start your first session

+```bash
+codeman web --https
+# Open on your phone: https://<your-ip>:3000
+```
+
+> `localhost` works over plain HTTP. Use `--https` when accessing from another device, or use [Tailscale](https://tailscale.com/) (recommended): the installer can set it up for you (choose **Tailscale** at the network-access prompt, or run `bash ~/.codeman/app/install.sh tailscale` on an existing install). That gives you `https://<your-machine>.<tailnet>.ts.net` with a real certificate: private to your tailnet, no password required, and PWA install + push notifications work on your phone.
+
+### Secure QR Code Authentication
+
+Typing passwords on a phone keyboard is miserable. Codeman replaces it with **cryptographically secure single-use QR tokens** — scan the code displayed on your desktop and your phone is authenticated instantly.
+
+Each QR encodes a URL containing a 6-character short code that maps to a 256-bit secret (`crypto.randomBytes(32)`) on the server. Tokens auto-rotate every **60 seconds**, are **atomically consumed on first scan** (replays always fail), and use **hash-based `Map.get()` lookup** that leaks nothing through response timing. The short code is an opaque pointer — the real secret never appears in browser history, `Referer` headers, or Cloudflare edge logs.
+
+The security design addresses all 6 critical QR auth flaws identified in ["Demystifying the (In)Security of QR Code-based Login"](https://www.usenix.org/conference/usenixsecurity25/presentation/zhang-xin) (USENIX Security 2025, which found 47 of the top-100 websites vulnerable): single-use enforcement, short TTL, cryptographic randomness, server-side generation, real-time desktop notification on scan (QRLjacking detection), and IP + User-Agent session binding with manual revocation. Dual-layer rate limiting (per-IP + global) makes brute force infeasible across 62^6 = 56.8 billion possible codes. Full security analysis: [`docs/qr-auth-plan.md`](docs/qr-auth-plan.md)

 ### Persistent Sessions
 
 Every session runs inside **tmux** — sessions survive server restarts, network drops, and machine sleep. Auto-recovery on startup with dual redundancy. Ghost session discovery finds orphaned tmux sessions. Managed sessions are environment-tagged so the agent won't kill its own session.
 
+### Session Manager & Command Palette
+
+`Ctrl/Cmd/Alt+K` opens a fuzzy session palette; **Browse all sessions** opens the Session Manager: one deduped list of everything Codeman knows about (live sessions, past sessions from state and lifecycle history, and Claude transcripts), each row showing its first and most recent prompt.
+
+- **Pinning**: pin a session to float it to the top of the list. Pinned sessions even survive kill (they demote to a lightweight stopped entry that stays visible and resumable).
+- **Name retention**: resuming a past session keeps its original name instead of minting a new one.

+- **Shared sessions**: several clients can attach the same remote session at different window sizes without clamping each other; discovery shows a "shared" badge with the client count.

+- **Loopback by default** — the server binary binds `127.0.0.1`, reachable only from the same machine, so the no-password default is safe out of the box (the guided installer asks about network access and configures the binding + password for you). Binding a non-loopback host without `CODEMAN_PASSWORD` _starts but prints a loud warning_ with three concrete fixes (set a password, loopback + an authenticated tunnel, or explicitly acknowledge with `--allow-unauthenticated-network`)
 - **Optional auth, real sessions** — HTTP Basic via `CODEMAN_USERNAME` (default `admin`) / `CODEMAN_PASSWORD`. Success issues an opaque 256-bit `codeman_session` cookie (`randomBytes(32)`) — validated server-side, not client-signed, so it can't be forged offline (24h TTL, auto-extend, device-context audit log)
 - **Per-IP rate limiting** — 10 failed attempts → `429` with `Retry-After` (15-min decay). A valid cookie or correct password recovers _immediately_ even while an attacker hammers the same IP — important because all tunnel traffic shares one loopback IP. QR auth has its own separate limiter
+- **Configurable permission mode** - `--dangerously-skip-permissions` is only the default. **App Settings → Claude CLI → Startup Mode** can switch new sessions to Anthropic's classifier-guarded `auto` mode (low-prompt, needs Claude Code 2.1.207+), `normal` prompting, or an explicit allowed-tools list.

+## 远程 SSH 会话
+
+把案例（case）指向另一台机器，通过 SSH 让智能体**在那台机器上**运行，同时保留同样的仪表盘、移动端 UI 与自主运行特性。你的笔记本只是一扇窗口，会话本体活在远程主机上。
+
+- **天生持久**：智能体运行在远程主机上一个专用的 tmux 会话里，SSH 断连、网络切换或笔记本休眠都不会中断任务。重新连接后回到同一个活跃对话。
+- **自动重连**：一个带上限退避的监视器发现 SSH 面板断开后，会静默重新附着到仍在运行的远程会话（设置中有总开关；主动杀掉的会话绝不会被复活）。
+- **发现与附着**：列出主机上已在运行的 `codeman-*` 会话（由那台机器自己的 Codeman 或其他操作者启动）并附着其一。非你所有的已附着会话在关闭标签时**只分离，绝不杀掉**。
+- **共享会话**：多个客户端可以以不同窗口尺寸同时附着同一个远程会话而互不挤压；发现列表会显示带客户端计数的「shared」徽标。
+- **注入安全**：所有 ssh 命令行都经由单一的 shell 转义构建器生成，主机/路径/身份文件字段均有模式校验。

+## 多用户模式（可选启用）
+
+与一个小型互信团队共享同一个 Codeman，每人拥有自己的登录与工作空间。**默认关闭**：不加该开关时，行为与单用户完全一致。
+
+用 `codeman web --multiuser`（或 `CODEMAN_MULTIUSER=1`）启用。创建第一个管理员后，可通过 CLI 或 App Settings 中的 **Users** 标签页管理用户：
+
+```bash
+codeman users add alice --admin      # 提示输入密码（或 --password-stdin）
+codeman users add bob                # 普通用户
+codeman users list
+```
+
+- **按用户的空间**：每个用户的案例位于 `~/codeman-users/<name>/cases`；会话、案例、搜索与实时事件都按属主隔离。管理员可以看到全部。
+- **可单独吊销的登录**：命名用户的密码以 scrypt 哈希保存在 `~/.codeman/users.json`；可随时禁用、重置（一次性密码）或删除账号。管理员操作审计记录在 `~/.codeman/admin-audit.jsonl`。
+- **普通用户的更安全默认值**：非管理员以 `--permission-mode auto` 运行 Claude（Anthropic 的分类器护栏模式）；raw shell 会话、cron `launchCommand` 与跳过权限模式需要按用户显式授权。
+
+> ⚠️ **这只是工作空间的划分，不是用户之间的沙箱。** 所有会话都以同一个操作系统账户运行，因此有心用户的智能体依然能触及他人的文件。若需要真正的隔离，请结合 **Docker 案例**，或在不同的操作系统账户下运行独立实例。参见 [`docs/multi-user-plan.md`](docs/multi-user-plan.md) 与 [`docs/security-architecture.md`](docs/security-architecture.md) 的多用户章节。

 - **按 IP 速率限制** —— 失败 10 次 → `429` 并带 `Retry-After`（15 分钟衰减）。即便攻击者在同一 IP 上猛攻，有效 cookie 或正确密码也能*立即*恢复 —— 这很重要，因为所有隧道流量共享同一个环回 IP。二维码认证有自己独立的限制器

+#### Asynchronous Rewake
+
+Command hooks can set `"asyncRewake": true` to run asynchronously and wake an
+idle Claude turn when the hook exits with code 2. The hook's stderr is delivered
+to Claude as a system reminder. This implies `"async": true`; ordinary async
+hooks do not wake an idle turn, and their output waits for the next interaction.
+
+Codeman uses this on `PostToolUse(Bash)`: a self-contained Node helper extracts
+the background task ID from the Bash result, watches the session transcript for
+the matching completion notification, and exits 2. It does not send terminal
+input, so it cannot submit a user's partially written prompt.

+# Extending Codeman
+
+Codeman has no plugin runtime, and that is a deliberate choice rather than a
+missing feature. A plugin runtime means running third-party code inside a process
+that spawns agents with your credentials, on a server people routinely expose
+over a tunnel or Tailscale. Codeman's security model is one of its reasons to
+exist, so it does not hand that away for an extension mechanism.
+
+Instead there are four seams that already work, from any language, with nothing
+installed:
+
+| You want to | Use | Runs where |
+| --- | --- | --- |
+| Show your own UI inside Codeman | [Web tabs](#seam-1-web-tabs) | Your own process, rendered as a tab |
+| React when an agent needs you | [SSE events](#seam-2-sse-events) | Anywhere that can hold an HTTP connection |
+| Drive Codeman from a script | [HTTP API](#seam-3-http-api-and-cli) or the `codeman` CLI | Anywhere |
+| React inside a Claude session | [Hooks](#seam-4-hooks) | The agent's own machine |
+
+Everything below is covered by the stability promise in
+[`versioning-policy.md`](versioning-policy.md): endpoint paths, the response
+envelope, `errorCode` values, and SSE event names are stable. Additive changes
+(new endpoints, new optional fields, new events) are non-breaking. Breaking
+changes ship under a new prefix (`/api/v2`).
+
+## Before you start
+
+**Base URL.** `http://127.0.0.1:3000` by default. Prefer the versioned prefix
+`/api/v1/...` for anything you publish; the unversioned `/api/...` is an alias.
+
+**Auth.** If `CODEMAN_PASSWORD` is set, send HTTP Basic on every request, or
+authenticate once and keep the `codeman_session` cookie. With no password set,
+Codeman is loopback-only and unauthenticated.
+
+```bash
+curl -u admin:$CODEMAN_PASSWORD http://127.0.0.1:3000/api/v1/sessions
+```
+
+**Envelope.** Every response is `{"success": true, "data": ...}` or
+`{"success": false, "error": "...", "errorCode": "..."}`. Check the HTTP status
+or `body.success`, then read `body.data`. The full `errorCode` to status mapping
+is in [`api-reference.md`](api-reference.md).
+
+## Seam 1: Web tabs
+
+The highest-leverage seam. Any web app you can serve locally becomes a tab beside
+your agent sessions. You write a normal web page; Codeman handles embedding it.
+
+```bash
+curl -u admin:$PASS -X POST http://127.0.0.1:3000/api/v1/webviews \
+  -H 'Content-Type: application/json' \
+  -d '{"name":"My Dashboard","url":"http://127.0.0.1:8787","icon":"📊"}'
+```
+
+Fields: `name` (1 to 60 chars), `url`, and optionally `icon` (a single glyph, max
+8 code units), `embedMode` (`proxy` by default, or `direct`), and `trusted`.
+
+Related endpoints: `GET /api/v1/webviews`, `PATCH /api/v1/webviews/:id`,
+`DELETE /api/v1/webviews/:id`, `POST /api/v1/webviews/probe` (reachability and
+framing check), `POST /api/v1/webviews/:id/open`.
+
+### Why it is proxied
+
+By default your page is served through Codeman's own origin at `/webview/:cap/*`
+rather than framed directly. A direct iframe fails three ways at once: production
+is HTTPS so `http://` targets are blocked as mixed content, many dashboards send
+`X-Frame-Options: DENY`, and Codeman's own `default-src 'self'` CSP blocks
+cross-origin frames. Proxying solves all three without weakening the CSP.
+
+### The two things that will confuse you
+
+A proxied frame is sandboxed and therefore **opaque-origin** unless you set
+`trusted: true`. Two consequences look like bugs in your own app:
+
+1. **Root-absolute URLs built at runtime** (`/assets/x.png` assembled in JS)
+   escape the injected `<base>` tag. Codeman injects a `runtimeUrlShim()` that
+   patches the common DOM sinks, but if you construct URLs in an unusual way,
+   prefer relative paths.
+2. **Same-host `fetch` and `XHR` are CORS-checked with `Origin: null`.** Codeman
+   handles this with `buildProxyCorsHeaders()`, and the proxy is exempt from the
+   global `OPTIONS` short-circuit. If you see "Failed to fetch" while the page
+   itself renders fine, this is the area to look at.
+
+⚠️ `trusted: true` opts out of the sandbox. A proxied page is served from
+Codeman's origin, so `allow-same-origin` lets it read the Codeman page and call
+the API that spawns agents. Only mark your own trusted code.
+
+## Seam 2: SSE events
+
+`GET /api/v1/events` is a Server-Sent Events stream. Each message is
+`event: <name>` plus `data: <json>`. There are 149 event names following a
+`domain:action` convention, registered in `src/web/sse-events.ts`.
+
+The ones most integrations want:
+
+| Event | Meaning |
+| --- | --- |
+| `session:created`, `session:deleted` | A session appeared or went away |
+| `session:idle` | The agent stopped working |
+| `session:completion` | A completion message was detected |
+| `session:exit`, `session:error` | The session ended or failed |
+| `hook:permission_prompt` | The agent is asking for permission |
+| `hook:idle_prompt`, `hook:stop` | The agent is waiting on you, or stopped |
+| `hook:task_completed`, `task:completed` | Work finished |
+| `subagent:discovered`, `subagent:completed` | Background agent lifecycle |
+| `mux:died` | A multiplexer session died unexpectedly |
+| `cron:runCreated`, `cron:runUpdated` | Scheduled job activity |
+
+### Filtering
+
+`?sessions=id1,id2` suppresses only the high-volume `session:terminal` stream for
+sessions you did not list. Lifecycle and metadata events are always delivered, so
+you cannot accidentally filter away the thing you are listening for.
+
+Pass `?clientId=<uuid>` to enable live filter updates through
+`POST /api/v1/events/subscribe` without reconnecting the stream.
+
+### Example: notify when any agent needs you
+
+```js
+const res = await fetch('http://127.0.0.1:3000/api/v1/events', {
+  headers: { Authorization: 'Basic ' + btoa(`admin:${process.env.CODEMAN_PASSWORD}`) },
+});
+const reader = res.body.getReader();
+const decoder = new TextDecoder();
+let buf = '';
+const WANTED = new Set(['hook:permission_prompt', 'hook:idle_prompt', 'session:idle']);
+
+for (;;) {
+  const { value, done } = await reader.read();
+  if (done) break;
+  buf += decoder.decode(value, { stream: true });
+  const frames = buf.split('\n\n');
+  buf = frames.pop() ?? '';
+  for (const frame of frames) {
+    const name = frame.match(/^event: (.+)$/m)?.[1];
+    const data = frame.match(/^data: (.+)$/m)?.[1];
+    if (name && WANTED.has(name)) notify(name, JSON.parse(data ?? '{}'));
+  }
+}
+```
+
+## Seam 3: HTTP API and CLI
+
+Around 199 handlers across 21 route files cover sessions, cases, files, cron,
+respawn, Ralph, the orchestrator, search, and admin. Each route module carries an
+`@fileoverview` describing its endpoints.
+
+The common ones:
+
+```bash
+# List sessions (live + persisted + transcript history, deduped)
+curl -u admin:$PASS http://127.0.0.1:3000/api/v1/sessions/unified
+
+# Create a session
+curl -u admin:$PASS -X POST http://127.0.0.1:3000/api/v1/sessions \
+  -H 'Content-Type: application/json' \
+  -d '{"workingDir":"/home/me/project","mode":"claude"}'
+
+# Send a prompt (single-line only, "\r" submits)
+curl -u admin:$PASS -X POST http://127.0.0.1:3000/api/v1/sessions/$ID/input \
+  -H 'Content-Type: application/json' \
+  -d '{"input":"run the tests","useScreen":true}'
+```
+
+For shell scripting, the `codeman` CLI is the same surface without the HTTP
+plumbing:
+
+```
+codeman session start|stop|list|logs     codeman task add|list|status|remove|clear
+codeman ralph start|stop|status|reset    codeman users add|passwd|list
+codeman status | list | attach <path>    codeman doctor
+```
+
+## Seam 4: Hooks
+
+Claude Code hooks post to `POST /api/v1/hook-event` from inside an agent session.
+Codeman installs its own hooks automatically, but the endpoint is open to yours.
+
+```json
+{ "event": "task_completed", "sessionId": "abc123", "data": { "any": "json" } }
+```
+
+`event` must be one of `permission_prompt`, `elicitation_dialog`, `idle_prompt`,
+`stop`, `teammate_idle`, `task_completed`. Each becomes the matching `hook:*` SSE
+event.
+
+⚠️ This endpoint skips Basic auth so hooks keep working, but when auth is active
+the loopback bypass requires the `X-Codeman-Hook-Secret` header
+(`~/.codeman/hook-secret`) unconditionally.
+
+## Gotchas
+
+Every one of these has cost somebody real time.
+
+- **CORS is localhost-only.** `Access-Control-Allow-Origin` is echoed only for
+  `localhost`, `127.0.0.1`, and `::1`. A browser app on any other origin cannot
+  call the API. Integrate server-side.
+- **A missing `Origin` header is allowed**, which is why curl, CLIs, and hooks
+  work. Cross-site origins are blocked by the CSRF guard.
+- **Reverse-proxy domains are rejected** by the anti-DNS-rebinding Host allowlist
+  unless added via `CODEMAN_ALLOWED_HOSTS=host,.suffix`.
+- **`null` is not `undefined`.** Request schemas use Zod `.optional()`, which
+  accepts `undefined` only. `JSON.stringify({ field: null })` keeps the null on
+  the wire and fails with `INVALID_INPUT`. Omit the key instead. This has caused
+  shipped bugs more than once.
+- **`text/plain` bodies stay raw.** Auto-parsing them as JSON enabled
+  simple-request CSRF, so it is deliberate. Send `application/json`.
+- **Prompts are single-line.** Input is delivered as text plus a separate Enter;
+  a multi-line string breaks the agent's input handling. Send `\r` to submit.
+- **Unwrap the envelope** before reading fields. `data` is not the response body.
+
+## Publishing your integration
+
+There is no registry and no review queue. Add the GitHub topic
+**`codeman-integration`** to your public repository so others can find it, and
+link back to Codeman in your README.
+
+If a real ecosystem of these appears, a manifest format and an install command
+become worth building. Until then, these four seams are the contract, and they
+require nothing of you but HTTP.
+
+## What Codeman deliberately does not have
+
+- **No in-process plugin runtime.** See the reasoning at the top of this page.
+- **No build or startup hooks** for third-party code. Run your own process.
+- **No per-plugin config or state directories.** Manage your own files.
+- **No sandbox**, because there is nothing to sandbox. Your integration is your
+  process, with your permissions, talking HTTP.

+| `GET /api/sessions/:id/file-raw`     | `1018` | Bytes, 50MB cap                                                    |
+| `GET /api/sessions/:id/file-preview` | `1254` | DOCX/PPTX to PDF, everything else redirects to `file-raw`           |
+| `GET /api/download`                  | `1384` | The only read route that also runs `isSensitivePath()`              |
+
+`file-content` classification order (`file-routes.ts:881-1011`): extension buckets (image / video / audio /
+known-binary) return metadata only; otherwise the bytes are read, sniffed for a NUL in the first 8KB, and
+either reported as `type:'binary'` or decoded as UTF-8 and **truncated to `lines` (default 500, hard cap
+10000)**. Caps: `MAX_TEXT_FILE_SIZE` 10MB.
+
+Confinement is `validateSessionFilePath()` (`src/web/route-helpers.ts:67`): `resolve()` then `realpathSync()`
+then reject if the result is not under `workingDir`. Because it realpaths the *full* path, a symlink whose
+target escapes the workspace is already rejected. Ownership is `findSessionOrFail()` which runs
+`canAccessOwned()` (`route-helpers.ts:102`), a no-op outside multi-user mode.
+
+**Read path (frontend), `src/web/public/panels-ui.js`:**
+
+- `loadFileBrowser()` `2947`, `renderFileBrowserTree()` `2978`, click to `openFilePreview()` `3056`.
+- `openFilePreview(filePath, sessionId, attachmentId)` `3193`: attachment-id branch, then docx/pptx, pdf,
+  svg branches, then the generic `file-content` fetch at `3274` with **`&lines=500` hardcoded**, rendering
+  text as `<pre><code>${escapeHtml(...)}</code></pre>` at `3298` and stashing `this.filePreviewContent`.
+- `closeFilePreview()` `3308`, `copyFilePreviewContent()` `3751`.
+- Markup: `src/web/public/index.html:420-432` (`filePreviewOverlay` / `-Title` / `-Body` / `-Footer`, two
+  header buttons: copy and close).
+- CSS: `src/web/public/styles.css:9320-9430`. Overlay `z-index: 2000`, window `80vw/80vh`, capped
+  `900x700`. There are **no `.file-preview-*` rules in `mobile.css` at all**.
+
+**Reachability on phones.** The header File Viewer button is hidden below 430px
+(`mobile.css:482`, locked by `KNOWN_PHONE_HIDDEN` in `test/mobile-header-buttons-policy.test.ts`), so on a
+phone the preview overlay is reached through:
+
+1. an attachment card's **Preview** button (`panels-ui.js:3451`), which is exactly the "agent just wrote a
+   file" path the issue describes,
+2. the attachment-history drawer (`panels-ui.js:3709`),
+3. App Settings to Panels to **File Browser** (`showFileBrowser`, applied in `settings-ui.js:2202`; the
+   panel is mobile-styled at `mobile.css:1868`).
+
+So edit mode is reachable on a phone today via (1) and (2) without touching the header policy. Improving
+the entry point is listed as an open decision in section 10, not assumed.
+
+---
+
+## 2. Threat model, stated honestly
+
+Anyone who can call this API can already reach `POST /api/sessions/:id/input` and type an arbitrary prompt
+into an agent running with `--dangerously-skip-permissions`. A workspace-confined write endpoint therefore
+does not create a new privilege tier for an authenticated caller.
+
+What it *would* create if built carelessly is a **new host-write primitive reachable by path**, so the
+things this plan actually defends against are:
+
+1. **Path traversal / symlink escape** writing outside the workspace.
+2. **TOCTOU**: a path component that becomes a symlink between validation and write.
+3. **Cross-user writes** in multi-user mode (`canAccessOwned`).
+4. **Silent data loss**, which is the highest-probability real-world failure here and gets its own section.
+
+CSRF is already covered: `registerHostGuard()` (`src/web/middleware/auth.ts:555-578`) rejects any
+non-safe-method request whose `Origin` is cross-site. The webview-capability exemption at that gate is
+fenced to `GET`/`HEAD` for the Referer form (`auth.ts:161`) and to `/webview/:cap/*` paths for the path
+form, so a proxied dashboard cannot reach a new `PUT /api/...`. Using `PUT` + `application/json` also
+forces a preflight for any cross-origin attempt.
+
+---
+
+## 3. Backend design
+
+### 3.1 New policy module: `src/config/file-editing.ts`
+
+Pure, unit-testable, no IO (config lives in `src/config/`, no barrel, import the file directly).
+
+```ts
+export const MAX_EDITABLE_BYTES = 512 * 1024;      // content cap, both directions
+export const EDITABLE_EXTENSIONS: ReadonlySet<string>;  // ts,tsx,js,jsx,mjs,cjs,json,jsonc,md,mdx,txt,
+                                                        // css,scss,less,html,htm,xml,svg?,yml,yaml,toml,
+                                                        // ini,cfg,conf,env?,sh,bash,zsh,fish,py,rb,go,rs,
+                                                        // java,kt,swift,c,h,cpp,hpp,cs,php,sql,graphql,
+                                                        // proto,lua,pl,r,jl,tf,gradle,csv,tsv,log,diff,patch
+export const EDITABLE_BASENAMES: ReadonlySet<string>;   // Dockerfile, Makefile, LICENSE, .gitignore,
+                                                        // .prettierignore, .editorconfig, .nvmrc, ...
+export function isEditableFileName(fileName: string): boolean;
+export function isDeniedEditRelativePath(rel: string): boolean;  // `.git/` subtree
+export function detectEol(text: string): 'lf' | 'crlf';
+export function applyEol(text: string, eol: 'lf' | 'crlf'): string;
+```
+
+Decisions baked in:
+
+- **Allowlist, not blocklist**, per the issue and per the existing attachment-guard precedent.
+- `svg` and `env` are deliberately marked with `?` above: `svg` is served as an untrusted octet-stream on
+  the read side (`file-routes.ts:118`) so allowing an edit is defensible, but I recommend **excluding
+  both** in v1. `.env` files are matched by `isSensitivePath()` anyway and would be rejected downstream;
+  excluding them at the allowlist keeps a single obvious refusal.
+- `isDeniedEditRelativePath` blocks the `.git/` subtree: `.git/hooks/*` is code execution and a corrupt
+  index is unrecoverable-looking to a user who only wanted to fix a typo. Other dotfiles stay allowed but
+  are not reachable from the tree UI anyway (`showHidden=false`).
+
+### 3.2 Read-for-edit: extend the existing GET
+
+`GET /api/sessions/:id/file-content?path=<rel>&edit=1`
+
+When `edit=1`:
+
+- skip line truncation entirely (a truncated buffer must never become an edit buffer, see section 4.1),
+- enforce `MAX_EDITABLE_BYTES` instead of `MAX_TEXT_FILE_SIZE` and answer 413 over it (as a structured
+  throw with `statusCode: 413`, the `throwFilesystemPickerError` pattern, since the central errorCode-to-
+  status map has no 413 entry; see the error-mechanics note in 3.3),
+- run the editability gate (`isEditableFileName`, `isDeniedEditRelativePath`, `isSensitivePath`,
+  `isBlockedAttachmentPath`) and the content gate (NUL sniff plus UTF-8 round-trip, see 4.3),
+- return `{ content, size, mtimeMs, totalLines, truncated: false, extension, editable: true, hash, eol }`.
+  `hash` is `sha256` hex of the exact on-disk bytes.
+
+Non-`edit` responses gain **only** `editable: boolean` (additive, no shape change for existing consumers),
+which is all the UI needs to decide whether to show the Edit button. No `hash` on plain reads: the Edit
+action re-fetches with `edit=1` anyway (section 4.1), which is where the hash comes from, and hashing every
+casual 10MB preview would be pure waste.
+
+### 3.3 Write: `PUT /api/sessions/:id/file-content`
+
+Body (new `FileWriteSchema` in `src/web/schemas.ts`, Zod v4):
+
+```ts
+{ path: string, content: string, baseHash: string, eol?: 'lf'|'crlf', force?: boolean }
+```
+
+Registered with an explicit route option `{ bodyLimit: 4 * 1024 * 1024 }`. **Fastify's default `bodyLimit`
+is 1MB and this repo configures none**, and JSON escaping expands content: 2x for a file full of quotes or
+backslashes, up to 6x for control characters (each serialized as a `\uXXXX` escape), so 512KB of content
+can legitimately exceed 1MB on the wire; blowing the limit produces a raw `FST_ERR_CTP_BODY_TOO_LARGE`, not an `ApiResponse` envelope. Two
+related sizing notes: `z.string().max()` counts **UTF-16 code units, not bytes**, so the schema's `.max()`
+is only a coarse pre-filter and the real cap is an explicit `Buffer.byteLength(content, 'utf8')` check in
+the handler (step 7a below); and 4MB comfortably bounds the worst-case expansion of a 512KB file without
+inviting multi-MB bodies elsewhere.
+
+**Error mechanics** (matters for both prod behavior and testability): a handler that *returns* a
+`{success:false, errorCode}` envelope gets its HTTP status assigned centrally by the preSerialization hook
+in `server.ts` (`httpStatusForErrorCode()`, `src/types/api.ts`), but the route-test harness
+(`test/routes/_route-test-utils.ts`) installs only `installRouteErrorHandler`, **not** that hook, so
+returned envelopes surface as HTTP 200 in tests. The PUT handler should therefore use the same
+structured-**throw** pattern as the filesystem picker (`throwFilesystemPickerError`, `file-routes.ts:411`):
+thrown `{statusCode, body}` errors are rendered identically in prod and in the harness, and they allow the
+one status the code map cannot express (413). The error envelope itself is strictly
+`{success:false, error, errorCode}`, **it has no data arm**, so no error response may carry extra payload.
+
+Handler order (each step is a test case):
+
+1. `findSessionOrFail(ctx, id, req)` (live sessions only, matching the read route, and it carries the
+   multi-user ownership check).
+2. `parseBody(FileWriteSchema, req.body)`, then `Buffer.byteLength(content, 'utf8') <= MAX_EDITABLE_BYTES`
+   or 413 (the schema `.max()` alone cannot enforce a byte cap, see the sizing note above).
+3. `validateSessionFilePath(session.workingDir, path)` or 404 (do not distinguish "outside workspace" from
+   "missing", matching the read route).
+4. `isSensitivePath(resolvedPath) || isBlockedAttachmentPath(resolvedPath, guard.blockedTrees)` or 403.
+5. `isDeniedEditRelativePath(relativePath)` or 403.
+6. `isEditableFileName(basename(resolvedPath))` or 400.
+7. `stat`: must be `isFile()`, size within `MAX_EDITABLE_BYTES`, else 400/413. **No `O_CREAT` anywhere in
+   this handler**, which is what enforces edit-in-place.
+8. Read current bytes, compute `hash`, run the NUL sniff and the UTF-8 round-trip check, else 400.
+9. `hash !== baseHash && !force` gives **409 CONFLICT** (`ApiErrorCode.CONFLICT`, plain envelope; the error
+   arm carries no data, see the error-mechanics note). The client's conflict dialog gets fresh state by
+   re-fetching `edit=1`, which it needs for its Reload action anyway.
+10. Build the output buffer: `applyEol(content, eol ?? detected-from-original)`; re-check
+    `Buffer.byteLength` against the cap.
+11. Write atomically in the resolved parent directory:
+    `fs.open(<dir>/.<name>.codeman-tmp-<rand>, 'wx', stat.mode & 0o777)`, then `fchmod(stat.mode & 0o777)`
+    (open's mode argument is masked by the process umask, so the chmod is what actually preserves an
+    unusual mode), write, `fsync`, close, `fs.rename(tmp, resolvedPath)`, unlink the temp on any failure.
+12. Re-stat, return `{ success: true, data: { path, size, mtimeMs, hash, totalLines } }`.
+
+Why `O_EXCL` temp plus rename rather than truncate-in-place:
+
+- `wx` cannot follow a pre-existing symlink, which closes the TOCTOU window from step 3 to step 11 without
+  needing `O_NOFOLLOW` gymnastics.
+- `rename()` does not follow a symlink in the final component, so even if `resolvedPath` were swapped for a
+  symlink after validation, the symlink itself is replaced and the swap target is untouched.
+- A crash mid-write leaves the original intact.
+
+Caveat to document in the code comment: rename replaces the inode, so hardlinks to the file keep the old
+content. That is the same trade-off vim makes by default and is preferable to a truncate window here.
+
+No SSE event in v1. Nothing else in the app needs to know: `image-watcher.ts` only reacts to
+`.png/.jpg/.jpeg/.gif/.webp/.bmp/.svg/.pdf/.docx/.pptx` adds (`image-watcher.ts:23-25`), none of which are
+editable text, and the temp filename does not match either.
+
+---
+
+## 4. The five traps
+
+These are the parts that turn a "small write endpoint" into a bug report.
+
+### 4.1 Truncation (the data-loss trap)
+
+The frontend fetches `&lines=500` (`panels-ui.js:3274`). Saving that buffer back would **delete every line
+past 500**. Worse, the content hash of the full file would still match, so an optimistic-concurrency check
+cannot catch it.
+
+Mitigations, all three:
+
+- The Edit affordance is only offered when the loaded payload came from `edit=1` (which never truncates).
+  Tapping Edit on an already-rendered preview **re-fetches** with `edit=1` before swapping in the editor.
+- The read-for-edit path 413s above `MAX_EDITABLE_BYTES` rather than truncating, so "too big to edit here"
+  is an explicit refusal with a message, never a silent partial buffer.
+- A test asserts `edit=1` never returns `truncated: true`.
+
+### 4.2 Line endings
+
+A `<textarea>`'s `.value` normalizes to LF. Saving a CRLF file naively rewrites every line, producing a
+whole-file diff for a two-line change. So: the read returns the detected `eol`, the client echoes it back
+unchanged, and the server re-applies it. Mixed-EOL files use the dominant style, which is lossy for the
+minority lines; call that out in the response and accept it in v1.
+
+### 4.3 Encoding
+
+`buf.toString('utf-8')` on a latin-1 or otherwise non-UTF-8 file yields U+FFFD replacement characters, and
+writing that back **corrupts the file**. The check is a round-trip:
+`Buffer.from(decoded, 'utf8').equals(buf)`. If it fails, `editable: false` and the write is refused. This
+also catches binary content that the NUL sniff misses. A UTF-8 BOM survives because it round-trips as a
+leading U+FEFF; do not strip it.
+
+### 4.4 Concurrency with the agent
+
+The whole use case is editing a file the agent just wrote and may write again. `baseHash` plus 409 is the
+guard. Do not use mtime alone: agents rewrite files within a single filesystem timestamp tick, and an
+identical rewrite should not be reported as a conflict.
+
+### 4.5 Symlinks and TOCTOU
+
+Covered by `validateSessionFilePath` (escape) plus `wx` temp and `rename` (post-validation swap). One
+intentional allowance: a symlink whose target is *inside* the workspace is edited through to its target,
+because `validateSessionFilePath` returns the realpath. That matches what a user tapping the file expects.
+
+---
+
+## 5. Frontend design
+
+All in `panels-ui.js` (prettier-exempt, hand-formatted; match the surrounding style), `index.html`,
+`styles.css`, `mobile.css`.
+
+### 5.1 State
+
+```js
+filePreviewEdit = { active, sessionId, path, baseHash, eol, original, dirty }
+```
+
+Reset in `closeFilePreview()` and on every `openFilePreview()` entry.
+
+### 5.2 Markup (`index.html:420-432`)
+
+Add one header button (pencil, `btn-icon-sm`, `id="filePreviewEditBtn"`, hidden by default) next to the
+copy button, and an edit bar inside the footer region holding Save / Cancel / a dirty dot. Keep the
+existing footer text element; the edit bar is a sibling toggled by class so the read-mode footer is
+untouched.
+
+### 5.3 Behavior
+
+- `openFilePreview()` shows the Edit button only when the response has `editable: true` and the render took
+  the text branch. Attachment-id previews, media, binary, pdf, docx/pptx and svg all leave it hidden.
+- **Enter edit**: re-fetch with `edit=1`; on 413 or `editable:false`, toast the reason and stay in read
+  mode. This fetch must **parse the error envelope on non-ok responses**: the existing generic
+  `if (!res.ok) throw new Error('Failed to load file')` pattern (`panels-ui.js:3275`) would swallow the
+  specific "too large to edit here" message, since error envelopes arrive with real 4xx statuses in prod. On success replace the body with `<textarea class="file-preview-editor" spellcheck="false"
+  autocapitalize="off" autocorrect="off" autocomplete="off" wrap="off">` and assign `.value = content`
+  (never `innerHTML`, so no escaping question arises). Do **not** autofocus: on a phone that opens the
+  keyboard before the user has picked a line.
+- `input` sets `dirty` and enables Save.
+- **Save**: `PUT` with `baseHash`, `eol`, and `content`. On success update `baseHash`/`original` from the
+  response, leave edit mode, re-render the read view from the local editor value (the response carries
+  metadata only, not content), toast "Saved". On **409** offer `Reload (discard mine)` / `Overwrite`:
+  Reload re-fetches `edit=1` and replaces the buffer; Overwrite re-sends with `force: true`. The 409 body
+  itself carries no state (section 3.3, step 9).
+- **Cancel / close / Escape while dirty**: `confirm('Discard unsaved changes?')`, consistent with the
+  existing `window.confirm` usage in this codebase (`panels-ui.js:4323`, `app.js:4176`). Note the global
+  Escape handler (`app.js:999-1007`) closes other panels via `closeAllPanels()` but does not touch this
+  overlay today; if Escape-to-close is wired up as part of this work it must go through the same dirty
+  guard.
+- `copyFilePreviewContent()` copies the live editor value while editing.
+
+⚠️ Repo gotcha to respect at the fetch call: **Zod `.optional()` rejects `null`**. Build the body with
+`eol: eol ?? undefined` (or declare `.nullish()`), or the PUT fails `INVALID_INPUT`. This has shipped as a
+real bug twice.
+
+### 5.4 Mobile
+
+- **Sizing.** The window is `80vw/80vh` centered with no mobile override, so when the keyboard opens on iOS
+  the lower half sits behind it. Add a `@media (max-width: 430px)` block using
+  `height: var(--app-height, 100vh)`, full width, no border radius. `--app-height` is already maintained
+  against `visualViewport` by `KeyboardHandler.handleViewportResize()` (`mobile-handlers.js:283-317`), so
+  the editor tracks the keyboard for free.
+- **iOS zoom.** The editor font must be >= 16px on phones; there is an existing zoom-prevention block at
+  `mobile.css` under `@media (max-width: 768px)`. Verify it covers `textarea` and do not override it with a
+  smaller `rem` value.
+- **Accessory bar.** Focusing any input fires `KeyboardHandler.onKeyboardShow()`, which calls
+  `KeyboardAccessoryBar.show()` and refits/resizes the terminal (`mobile-handlers.js:407+`). The bar's keys
+  target the **terminal**, not the editor, so an Esc or clear-input tap while editing goes to the agent.
+  The overlay's `z-index: 2000` covers the bar's `51`, so it is not visible, but confirm it is not
+  interactive underneath and consider an explicit `KeyboardAccessoryBar.hide()` while the editor holds
+  focus. This is the item most likely to look "fine on desktop, wrong on the phone".
+- No header-policy change is needed (section 1), so
+  `test/mobile-header-buttons-policy.test.ts` stays untouched.
+
+### 5.5 i18n
+
+`i18n.js` already skips `textarea`, `pre`, `code` and `.file-preview-content` in its `SKIP_SELECTOR`
+(`i18n.js:20-38`), so file content is never translated. Add zh-CN entries for the new chrome: Edit, Save,
+Cancel, Unsaved changes, Discard unsaved changes?, File changed on disk, Reload, Overwrite, Saved,
+Too large to edit here.
+
+---
+
+## 6. Docker and remote cases
+
+Out of scope per the issue, and the current behavior already degrades correctly:
+
+- **Docker cases**: the workspace is a host directory bind-mounted at the same absolute path, so a host-side
+  write is visible in the container immediately. Edit mode works and needs nothing special. Worth one line
+  in the docs.
+- **Remote SSH cases**: `workingDir` is a path on the remote host. `validateSessionFilePath` realpaths it
+  locally, which fails, so the write returns 404 exactly like the read routes do today. Confirm the viewer
+  shows a clean empty/error state rather than an unexplained failure, and do not attempt an SFTP path.
+
+---
+
+## 7. Tests
+
+| File                                        | Kind        | Covers                                                                 |
+| ------------------------------------------- | ----------- | ---------------------------------------------------------------------- |
+| `test/file-editing-policy.test.ts`          | pure unit   | `isEditableFileName` (allow + deny + basenames), `isDeniedEditRelativePath`, `detectEol`/`applyEol` round-trip incl. mixed EOL, BOM preservation |
+| `test/routes/file-write-routes.test.ts`     | `app.inject` | The handler order in 3.3, against a **real temp dir** (do not `vi.mock('node:fs')` in this file; set `MockSession.workingDir`, `test/mocks/mock-session.ts:14`) |
+| extend `test/routes/file-routes.test.ts`    | `app.inject` | `edit=1` never truncates; `editable` present on the plain read          |
+
+Status-code caveat for all of these: the route-test harness does not install the server's preSerialization
+envelope hook, so a handler that *returns* an error envelope answers 200 in tests. The statuses below are
+only assertable because the plan has the handler **throw** structured errors (section 3.3, error
+mechanics), which `installRouteErrorHandler` renders identically in prod and in the harness.
+
+Route cases to assert explicitly:
+
+1. happy path writes the bytes and returns a new hash
+2. `../` and absolute paths give 404
+3. symlink pointing outside the workspace gives 404
+4. symlink pointing inside is written through to the target
+5. non-allowlisted extension gives 400
+6. `.git/config` gives 403
+7. a `.env` in the workspace gives 403 (sensitive-path)
+8. a file with a NUL byte gives 400
+9. a latin-1 file that fails the UTF-8 round-trip gives 400
+10. stale `baseHash` gives 409 (`CONFLICT` envelope, no data); `force:true` then succeeds
+11. over `MAX_EDITABLE_BYTES` gives 413
+12. a path that does not exist gives 404 and creates nothing (no `O_CREAT`)
+13. multi-user: `authUser: {role:'user'}` against another user's session gives 404 (pass `authUser` to
+    `createRouteTestHarness`, otherwise the synthetic admin makes the test pass vacuously)
+14. CRLF file edited and saved stays CRLF
+15. file mode is preserved across the temp-plus-rename
+
+Run with `npm test -- test/routes/file-write-routes.test.ts`, never bare `npm test`.
+
+**End-to-end verification before any deploy** (unit tests passing is not sufficient here):
+
+- `curl -sk https://localhost:3000/...` against a **throwaway** session created for the purpose, never
+  `w1`/`w2`/`w3`; delete it by exact id afterwards.
+- Playwright on a phone profile: open a preview, tap Edit, type with `page.keyboard.type()`, Save, then
+  assert the bytes on disk changed. Assert real state, not HTTP 200.
+
+---
+
+## 8. Docs and release
+
+- This plan lives at `docs/file-viewer-edit-plan.md`.
+- `docs/architecture-invariants.md`: new anchor `#file-viewer-edit-mode` covering the write confinement
+  chain, the truncation invariant, and why temp-plus-rename.
+- `CLAUDE.md`: one line under the **Filesystem path picker** neighborhood noting that the File Viewer now
+  has a **third** file surface and that it is the only one that writes, plus its confinement rules.
+  Remember `CLAUDE.md` is prettier-ignored on purpose.
+- `docs/api-reference.md`: the new `PUT` and the `edit=1` query.
+- Release: a normal COM applies (the 1.10.0 batch hold is over). This is a new user-facing feature plus an
+  additive API surface, so **COM minor** when it ships.
+
+Formatting note: `panels-ui.js`, `styles.css`, `mobile.css`, `index.html` are all in `.prettierignore` and
+are hand-formatted; new TypeScript (`src/config/file-editing.ts`, route + schema edits) is prettier-enforced
+and must pass `npm run format:check`.
+
+---
+
+## 9. Implementation order
+
+Each phase is independently reviewable and leaves the tree working.
+
+1. **Policy module + tests.** `src/config/file-editing.ts` and `test/file-editing-policy.test.ts`. Pure, no
+   route wiring. (Small.)
+2. **Read-for-edit.** `edit=1` (returning `hash`/`eol`) plus the additive `editable` flag on plain reads,
+   tests. Nothing consumes it yet. (Small.)
+3. **Write endpoint.** `FileWriteSchema`, `PUT` handler, `test/routes/file-write-routes.test.ts`. Fully
+   testable by curl before any UI exists. (Medium, the security-relevant part.)
+4. **Desktop UI.** Edit button, textarea swap, Save/Cancel, dirty guard, 409 flow. (Medium.)
+5. **Mobile pass.** `mobile.css` sizing against `--app-height`, font size, accessory-bar interaction,
+   real-device check. (Small but the part that decides whether the feature is actually usable.)
+6. **Docs, i18n strings, changeset.**
+

+
+## 10. Open decisions
+
+1. **Editor widget.** Recommend a plain `<textarea>` for v1: zero dependencies, no CSP question, no bundle
+   growth, and it is the only thing guaranteed to behave with the iOS keyboard. CodeMirror-light with
+   syntax highlighting is a clean follow-up once the write path is proven. The issue allows either.
+2. **Phone entry point.** Edit mode is reachable on a phone through attachment cards and the history
+   drawer without changing anything. A dedicated toolbar or overview affordance for "browse this session's
+   files" would make it discoverable, but it is a separate UX change and would need a decision against the
+   deliberately minimal phone header policy. Recommend deferring it and revisiting after the feature ships.
+3. **`svg` editability.** Recommend excluded in v1 (it is deliberately treated as untrusted on the read
+   side). Easy to add later.
+4. **Create / delete / rename.** Explicitly out of scope per the issue. Note that keeping `O_CREAT` out of
+   the handler is what makes that a structural property rather than a convention.

+- **The proxy is exempt from cookie auth and the Origin/CSRF guard, and that is deliberate.** The iframe is sandboxed without `allow-same-origin`, so it is opaque‑origin: its requests are cross‑site, meaning the `SameSite=lax` session cookie is never attached and its writes and WS upgrades arrive with `Origin: null`. The credential is instead a 192‑bit capability in the path, minted only by an authenticated `POST /api/webviews/:id/open`, held in memory (a restart invalidates every one), rolling TTL, bound to the minting user, and granting nothing but "relay bytes to this one saved URL". ⚠️ **The Host allowlist is NOT bypassed**, so DNS‑rebinding protection is unaffected. A second `Referer`‑keyed form exists for root‑absolute assets and is the only exemption decided by a request‑supplied header, so it is fenced to safe methods on non‑`/api`, non‑`/ws`, non‑`/q` paths. Edges pinned by `test/webview-auth-exemption.test.ts`.
+- **Sandboxed by default; `allow-same-origin` is an explicit per‑dashboard opt‑in.** A proxied page is same‑origin with Codeman, so without the sandbox its JavaScript could read the Codeman document and call the agent‑spawning API. ⚠️ In BOTH modes the `Authorization` header and the `codeman_session` cookie are stripped before the upstream request, because a trusted (same‑origin) frame makes the browser attach Codeman's own Basic‑auth credentials to every proxied request; forwarding them would hand `CODEMAN_PASSWORD` to the dashboard.
+- **Not an open relay, and not a privilege boundary.** `resolveUpstreamUrl()` refuses anything leaving the saved origin, and cross‑origin redirects are handed back unchanged rather than followed. The proxy does reach whatever the SERVER can reach, which is not an escalation for someone who already commands `--dangerously-skip-permissions` agents, but in multi‑user mode it means a non‑admin's dashboard is fetched from the server's network position. Saved URLs are validated to plain http(s) with no embedded credentials, and there is deliberately **no magic‑link path**: terminal output can never create a webview (the mistake the attachment scanner had to be walled off from).

+# Tailscale Setup in the Installer (Plan)
+
+Goal: make "Codeman over Tailscale, with real HTTPS" a first-class, guided path in
+`install.sh`, instead of a one-line hint pointing at the docs. Today the safest
+recommended deployment (loopback bind + `tailscale serve`) is exactly what the
+maintainer's own prod runs, but a new user has to discover and wire it by hand.
+The installer should do it for them.
+
+Status: IMPLEMENTED (2026-08-04). `install.sh` carries the 3-way network
+prompt, the guided Tailscale flow, and the `tailscale` subcommand; README,
+`docs/security-architecture.md` section A, and CLAUDE.md are updated. Verified
+live on the maintainer's prod host: `install.sh tailscale` took the idempotent
+kept-as-is path against the existing serve mapping (recognizing the legacy
+`https+insecure://` target), verified `https://<node>.ts.net/api/status`
+end-to-end, and left `tailscale serve status` byte-identical. Items 1-4, 7,
+and 10-12 of the manual matrix below still need a fresh machine to exercise.
+
+## Why this is low-hanging fruit
+
+Everything on the app side already works; this is almost purely installer UX:
+
+- `.ts.net` is already in `DEFAULT_TRUSTED_HOST_SUFFIXES`
+  (`src/web/network-auth-policy.ts`), so the always-on Host/Origin guard accepts
+  `tailscale serve` traffic with zero configuration. No `CODEMAN_ALLOWED_HOSTS`
+  needed.
+- The loopback bind is the server default and prints no warning; nothing to
+  acknowledge, no `CODEMAN_PASSWORD` strictly required (the tailnet is the auth
+  boundary; Tailscale authenticates the device before a packet ever reaches us).
+- `tailscale serve` terminates TLS with a real Let's Encrypt certificate for
+  `<node>.<tailnet>.ts.net`. That gives users valid HTTPS with no self-signed
+  cert warnings, and (because it is a proper secure context) working service
+  worker, PWA install, and web push on phones. This is strictly better than
+  `codeman web --https` for remote access.
+- SSE and WebSockets work through serve (proven by prod:
+  `https://tnode.tailf80371.ts.net` fronting `127.0.0.1:3000` daily).
+- `docs/security-architecture.md` section "A. Tailscale serve (recommended)"
+  already documents this as the preferred setup; the installer just does not
+  implement it.
+
+## UX design
+
+### 1. The network-access prompt grows a Tailscale option
+
+`choose_network_binding()` (install.sh:1051) currently offers two choices. New
+menu, with Tailscale first when it can be recommended:
+
+```
+  Network access
+
+  How should the Codeman dashboard be reachable?
+
+    1) Tailscale (recommended)
+       Private VPN access from your phone/laptop, real HTTPS,
+       no password needed. Works from anywhere, not just your Wi-Fi.
+    2) Any device on your network (0.0.0.0)
+       Open it straight from your phone or laptop on the same Wi-Fi.
+       Less safe: set a password so only you control your agents.
+    3) This machine only (127.0.0.1)
+       Safest. Reach it remotely via Tailscale or a tunnel later.
+```
+
+Choice mapping:
+
+- Option 1 = bind `127.0.0.1` (unchanged server posture) + configure
+  `tailscale serve`. Internally it is option 3 plus the serve setup, so all
+  existing binding plumbing (`BIND_HOST`, service files, `read_existing_binding`)
+  is untouched.
+- Options 2 and 3 behave exactly as today (renumbered).
+- Default choice: 1 when tailscale is installed and logged in, or when an
+  existing serve mapping for our port is detected; otherwise keep today's
+  defaults (1 -> 2, 2 -> 3 renumbering, preserving the "existing setup wins"
+  rule). If tailscale is not installed, option 1 is still shown (the installer
+  offers to install it), but the default stays on the current behavior so a
+  bare Enter never pulls in new software.
+- Password: after choosing Tailscale, offer the password prompt as optional
+  defense in depth with default skip ("the tailnet already authenticates your
+  devices; add one anyway?"). No `BIND_ACK` needed since the bind is loopback.
+
+### 2. The Tailscale flow (state machine)
+
+New `setup_tailscale_access()` runs after the binding choice, before service
+setup, handling each state in order:
+
+1. **Not installed.**
+   - Linux: offer to run the official installer
+     (`curl -fsSL https://tailscale.com/install.sh | sh`), which handles all
+     distros and enables `tailscaled` at boot. This mirrors our own
+     curl-pipe-bash story and avoids maintaining per-distro logic like the six
+     `install_cloudflared_*` functions.
+   - macOS: do not auto-install (the GUI app needs an interactive login).
+     Offer `brew install --cask tailscale` when brew exists, else print the
+     download link, then wait-and-retry or let the user skip.
+   - Declined install => fall back to plain loopback (option 3 behavior) and
+     print how to redo this later (`install.sh tailscale`, see below).
+2. **Installed but logged out** (`tailscale status --json` ->
+   `.BackendState == "NeedsLogin"` or `"Stopped"`).
+   - Run `tailscale up` (via `run_as_root` if needed). It prints an auth URL
+     that works headless (user opens it on any device). Poll
+     `.BackendState == "Running"` with a friendly spinner + timeout; on
+     timeout, skip gracefully with re-run instructions.
+3. **Running: grant operator (Linux).** `sudo tailscale set --operator=$USER`
+   so serve configuration (now and in the future) does not need root. Skip
+   silently if we are already operator (probe: `tailscale serve status`
+   exits 0) or sudo is declined; fall back to `run_as_root tailscale serve ...`.
+4. **HTTPS availability check.** `.CertDomains` empty or
+   `.CurrentTailnet.MagicDNSEnabled == false` means the tailnet has not enabled
+   MagicDNS / HTTPS certificates. Print the exact two toggles with the admin
+   URL (https://login.tailscale.com/admin/dns: enable MagicDNS, then enable
+   HTTPS Certificates), then offer "I enabled it, re-check" / "skip for now".
+   No silent HTTP fallback: the pitch is real HTTPS, and a plain-HTTP serve
+   would break the PWA/push story. Skipping falls back to loopback + re-run
+   instructions.
+5. **Existing serve config check** (`tailscale serve status --json`).
+   - Already proxying to our port (443 -> `127.0.0.1:$PORT`): keep it, report
+     it, done. Re-running the installer must be idempotent.
+   - Port 443 occupied by a DIFFERENT target: never clobber it. Ask whether to
+     replace it or skip. (Prod itself has a second serve on :5000; blind
+     `tailscale serve reset` would destroy user config. NEVER use `reset`.)
+6. **Configure.** `tailscale serve --bg $PORT` where `$PORT` is the install's
+   Codeman port (default 3000; honor a preset `CODEMAN_PORT`). Serve targets
+   plain HTTP on loopback; TLS terminates at tailscaled with the real cert.
+   The `--bg` config persists in tailscaled state across reboots, so no extra
+   service unit is needed.
+   (Note: do NOT combine this with `codeman web --https`; that is what forces
+   the awkward `https+insecure://` proxy target prod historically used. New
+   installs should keep Codeman on plain HTTP behind serve.)
+7. **Verify end-to-end.** Derive the URL from `.Self.DNSName` (strip the
+   trailing dot) and curl `https://<dnsname>/api/status` after the service is
+   up, retrying for ~30s: the first request can be slow while the Let's
+   Encrypt cert is issued. Print success with the URL, or the observed error
+   with `tailscale serve status` output on failure. This follows the "always
+   test before claiming it works" rule; a blind "done!" is not acceptable.
+
+### 3. Closing summary and security notice
+
+- The final summary gains a "Remote Access (Tailscale)" block, printed above
+  the cloudflared block, showing the actual URL:
+
+  ```
+    Remote Access (Tailscale):
+      https://tnode.tailf80371.ts.net    (any device on your tailnet, HTTPS)
+      tailscale serve status             # inspect
+  ```
+
+- `print_security_notice()` third branch (loopback) gets a variant: when a
+  serve mapping for our port is detected, lead with "reachable on your tailnet
+  at https://... (HTTPS, tailnet-only)" instead of the generic "do ONE of"
+  list. Detection is dynamic (query `tailscale serve status --json` at print
+  time), no marker persisted anywhere: tailscaled's own state is the single
+  source of truth, so external changes never drift against a stale flag.
+
+### 4. Standalone entry point: `install.sh tailscale`
+
+Add a `tailscale` subcommand next to `update` / `uninstall` in the existing
+dispatch. It runs `setup_tailscale_access()` against the already-installed
+service (reads the port from the service file, requires an existing install).
+This serves:
+
+- existing installs that predate the feature,
+- users who picked "this machine only" and changed their mind,
+- every "skip for now" branch above, all of which print this exact command.
+
+One implementation, two entry points. No separate `scripts/tailscale-setup.sh`
+(unlike cloudflared, there is no long-running process for a `tunnel.sh`-style
+start/stop wrapper to manage; tailscaled owns the lifecycle).
+
+### 5. Non-interactive / automation
+
+- `CODEMAN_TAILSCALE=1` presets choice 1 (analogous to presetting
+  `CODEMAN_HOST`). In non-interactive runs it only proceeds through states
+  that need no human (already installed + logged in + HTTPS-enabled tailnet);
+  anything requiring interaction (login URL, admin-console toggle, replacing a
+  foreign serve mapping) warns and falls back to loopback. It never installs
+  tailscale non-interactively.
+- `CODEMAN_NONINTERACTIVE=1` with an existing serve mapping: preserve it, same
+  "never silently loosen/change" policy as `read_existing_binding`.
+- Document both in the header comment block of install.sh (the env-var
+  reference at the top) and in the README.
+
+## Edge cases and decisions
+
+| Case | Decision |
+| ---- | -------- |
+| macOS GUI app without `tailscale` on PATH | `get_tailscale_path()` helper mirroring `get_cloudflared_path()`: check PATH, then `/Applications/Tailscale.app/Contents/MacOS/Tailscale`. All calls go through it. |
+| Tailnet HTTPS certs disabled | Guided admin-console instructions + re-check loop; skip falls back to loopback. Never configure plain-HTTP serve. |
+| Port 443 serve exists for another app | Prompt replace/skip; never `tailscale serve reset` (destroys unrelated mappings). |
+| First cert issuance latency | Verify step retries ~30s and says why the first load may be slow. |
+| `tailscale up` needs auth | Print the auth URL prominently, poll with timeout, skip gracefully. Works headless. |
+| Custom `CODEMAN_PORT` | Serve target uses the actual port; `install.sh tailscale` re-reads it from the service file. |
+| Funnel (public internet) | OUT OF SCOPE for v1. If ever added it must mirror the tunnel guard: refuse without `CODEMAN_PASSWORD` (`isUnauthenticatedNetworkAcknowledged`). Funnel exposes to the whole internet and is a different risk class than tailnet-only serve. Mention `tailscale funnel` in docs only, with the password warning. |
+| Uninstall | Best effort: if `serve status --json` shows 443 proxying to our port, run the targeted `tailscale serve --https=443 off` (still accepted by current CLIs); if the CLI rejects it, print manual instructions. Never touch other mappings, never uninstall tailscale itself. |
+| User already fronting Codeman some other way (reverse proxy etc.) | The serve check only looks at tailscale state; other proxies are invisible and unaffected (same stance as the loopback-exemption note in security-architecture). |
+
+## What does NOT change
+
+- Server code: no changes required. Host guard already trusts `.ts.net`,
+  loopback bind is already the default, SSE/WS already work through serve.
+- The two existing binding options and their semantics, `read_existing_binding`
+  preservation, and the LAN+password flow.
+- `scripts/tunnel.sh` / cloudflared support (stays as the "no Tailscale
+  account" alternative).
+- The security model: this feature only ever narrows exposure (loopback +
+  authenticated overlay), never widens it.
+
+## Files touched (implementation inventory)
+
+| File | Change |
+| ---- | ------ |
+| `install.sh` | New: `check_tailscale`, `get_tailscale_path`, `tailscale_status_field` (jq-free JSON field extraction; the installer cannot assume jq: use `sed`/`grep` like existing helpers or `tailscale status --json` piped to `node -e` since node is guaranteed post-install), `offer_install_tailscale`, `ensure_tailscale_login`, `ensure_tailscale_operator`, `ensure_tailnet_https`, `setup_tailscale_serve`, `verify_tailscale_access`, `setup_tailscale_access` (orchestrator). Modified: `choose_network_binding` (3-way menu), summary block, `print_security_notice`, subcommand dispatch (`tailscale`), `uninstall` (targeted serve removal), header env-var docs (`CODEMAN_TAILSCALE`). |
+| `README.md` | Remote-access section: promote the Tailscale path with the one-liner and `install.sh tailscale`; keep the tailscale-IP HTTP note for non-serve users but recommend serve + HTTPS. |
+| `docs/security-architecture.md` | Section A gains "the installer can set this up for you" + `install.sh tailscale` pointer. |
+| `CLAUDE.md` | One line in Scripts & Tunnel: installer offers Tailscale setup (`install.sh tailscale` to redo). |
+| `test/` | No unit tests possible for interactive bash + a live tailnet; guard with `shellcheck install.sh` (already the norm) and the manual matrix below. |
+
+## Manual test matrix (before release)
+
+1. Linux + tailscale absent: install offered, declined => loopback fallback + hint.
+2. Linux + tailscale absent: install accepted => full flow => URL verified.
+3. Logged out => auth URL flow => Running => serve configured.
+4. Tailnet with HTTPS certs disabled => guided instructions => re-check => success; and the skip branch.
+5. Re-run installer with serve already configured => idempotent, preserved, reported.
+6. Second serve mapping on another port present => untouched (prod-like state).
+7. Port 443 already proxying another target => replace/skip prompt honored.
+8. `install.sh tailscale` on an existing loopback install (the retrofit path).
+9. `CODEMAN_NONINTERACTIVE=1` re-run => preserves everything, no prompts.
+10. macOS (Mac mini `arbbot` box): GUI-app CLI path detection + full flow.
+11. Uninstall removes only our 443 mapping, leaves others.
+12. Phone check: PWA install + push from the `https://*.ts.net` origin.
+
+## Release
+
+Changeset: `minor` (new documented installer capability + new `CODEMAN_TAILSCALE`
+env var). The feature is installer-only, so it ships with zero risk to running
+servers; `install.sh update` does not invoke the new flow (updates never rewrite
+access config), only fresh installs and the explicit `install.sh tailscale`
+subcommand do.

+- Text selected in the terminal + `Ctrl+C` -> copy the selection, toast, clear the selection, do NOT send the byte to the PTY.
+- No selection + `Ctrl+C` -> unchanged, the interrupt (`0x03`) reaches the PTY.
+- `Ctrl+Shift+C` as an explicit copy chord.
+- The selection check must run before the shortcut registry dispatch so a rebind cannot cost the user their interrupt key.
+- Paste is out of scope (it already works via `Ctrl+V`, which terminal-ui.js routes to the image/text paste trap).
+
+## 2. Verified current behavior
+
+### 2.1 xterm cancels the Ctrl+C keydown, so no copy can happen
+
+`src/web/public/vendor/xterm.min.js` (xterm 6.x), `_keyDown`:
+
+```js
+_keyDown(x){ if(this._keyDownHandled=!1, this._keyDownSeen=!0,
+  this._customKeyEventHandler && this._customKeyEventHandler(x)===!1) return !1;
+  ... evaluateKeyboardEvent(...) ... this.cancel(x) ... }
+```
+
+Two consequences that shape the design:
+
+1. The custom handler runs **first**, before xterm evaluates the key. Returning `false` exits before `cancel(x)`, so returning `false` does **not** call `preventDefault()` for us.
+2. When the handler returns `true`, xterm turns Ctrl+C into `0x03` and cancels the event, which is why the browser's own copy command never runs.
+
+Probe (headless chromium against an isolated server on port 3174, selection active, real focus on `.xterm-helper-textarea`, synthetic Ctrl+C keydown):
+
+```json
+{ "hasSelection": true, "defaultPrevented": true, "dataSeen": ["\"\\u0003\""],
+  "clipboardAfter": "SENTINEL-BEFORE", "stillHasSelection": false }
+```
+
+So today: interrupt byte sent, clipboard untouched, and xterm drops the selection anyway. The last point matters, "copy then clear the selection" is not a behavior change in how the selection feels, it is what already happens on any keypress.
+
+### 2.2 Why right-click Copy works today
+
+xterm registers a `copy` listener on its root element that substitutes the selection text:
+
+```js
+this._register(addDisposableListener(this.element,"copy",(k=>{ this.hasSelection() && copyHandler(k,this._selectionService) })))
+```
+
+Second probe (port 3175, real `page.keyboard.press('Control+c')`, custom handler patched to return `false` for Ctrl+C without `preventDefault`):
+
+```json
+{ "dataSeen": [], "copyEvents": ["xterm-element"],
+  "clipboardAfter": "native-copy-probe-line\n...", "stillHasSelection": true }
+```
+
+So a "return false and let the browser copy" implementation would also work in Chromium. It is rejected below (section 3.3) because it gives no toast, does not clear the selection, and leans on per-browser behavior of the copy command when the focused element is xterm's empty helper textarea.
+
+### 2.3 The document-level capture handler will not interfere
+
+`setupEventListeners()` in `src/web/public/app.js:989` runs on document capture, before xterm's textarea listener. Its registry loop skips any entry whose action is not in the local `SHORTCUT_ACTIONS` map:
+
+```js
+if (shortcut.disabled || !shortcut.action) continue;
+const action = SHORTCUT_ACTIONS[shortcut.action];
+if (!action) continue;
+```
+
+This is exactly how `command-palette` already behaves: it is a full registry entry (rebindable and disableable in App Settings) whose dispatch happens in a dedicated, focus-aware gate rather than the generic loop. The new copy entry follows that pattern, so the capture handler falls through untouched and the terminal handler owns the decision.
+
+### 2.4 Registry matching rules that constrain the bindings
+
+`matchesShortcutEvent()` (`app.js:4890`):
+
+- Ctrl and Cmd are interchangeable as the primary modifier, so a `['ctrl']` binding also matches Cmd+C on macOS. That is fine here: with a selection it copies (same result the native macOS path gives today), without one it falls through.
+- Every other modifier must be declared exactly: `if (mods.includes('shift') !== !!e.shiftKey) return false`. So `Ctrl+Shift+C` needs its own binding, a plain `ctrl+c` binding will never swallow it.
+- `binding.code` wins when present, otherwise `binding.key` is compared case-insensitively.
+
+### 2.5 Where selection is actually possible
+
+- The server strips mouse-tracking DECSETs for `claude`, `codex`, and `gemini` (`isAltScreenStripMode`, `src/session.ts:179`), which is why plain drag-select works in those tabs even though the TUI has mouse tracking on.
+- `shell`, `opencode`, and `antigravity` keep mouse reporting, so xterm requires `Shift`+drag to force a selection there. Worth one line in the docs, it is not a code change.
+- Touch devices deliberately disable selection entirely (`body.touch-device .terminal-container .xterm{user-select:none !important}`, `styles.css:3196`), and phones have no Ctrl key. This feature is desktop and hardware-keyboard only, with no mobile regression surface.
+
+### 2.6 Helpers that already exist and should be reused
+
+| Need | Existing code |
+| --- | --- |
+| Clipboard write with an HTTP-safe fallback | `_copyText(text)` in `app.js:1887` (Clipboard API, then hidden textarea + `execCommand`) |
+| Toast | `showToast(message, type)` in `panels-ui.js:4385` |
+| Translated string | `'Copied to clipboard'` already in `i18n.js:453` |
+| Focus-aware chord gate to copy the shape of | `shouldOpenCommandPaletteFromShortcut(e)` in `panels-ui.js:285` |
+| Buffer-wide copy (currently unreferenced) | `copyTerminal()` in `terminal-ui.js:2615` |
+
+`_copyText` matters more than it looks: `install.sh`'s LAN option serves plain HTTP, where `navigator.clipboard` is undefined. The issue's suggested `navigator.clipboard.writeText` alone would silently do nothing for those users, the `execCommand` fallback covers them.
+
+## 3. Design
+
+### 3.1 Behavior
+
+| Chord | Selection present | No selection |
+| --- | --- | --- |
+| `Ctrl+C` (and Cmd+C, per registry equivalence) | copy, toast, clear selection, swallow the key | fall through, xterm sends `0x03` (interrupt) |
+| `Ctrl+Shift+C` | copy, toast, clear selection, swallow the key | swallow, no-op (see 3.2) |
+| Shortcut disabled in App Settings | never copies, `Ctrl+C` is always the interrupt | unchanged |
+| Rebound to another chord | that chord copies when a selection exists | plain `Ctrl+C` is always the interrupt |
+
+### 3.2 Why `Ctrl+Shift+C` with no selection is swallowed rather than forwarded
+
+Today `Ctrl+Shift+C` produces `0x03` as well (the shift is irrelevant to the control byte), so forwarding would be "no regression". But once the chord is advertised as *the explicit copy key*, letting it interrupt a running agent when the selection happens to be empty is a footgun with no upside. Swallowing costs nothing: a user who wants to interrupt has `Ctrl+C` right there.
+
+The rule in code is "no selection and the matched chord had Shift -> swallow", not a hardcoded key check, so it stays correct under rebinds.
+
+### 3.3 Why an explicit clipboard write rather than falling through to the native copy
+
+Probe 2 showed the native path works in Chromium, but the explicit write is chosen because it:
+
+- gives the "Copied to clipboard" toast, which is the discoverability half of the issue,
+- clears the selection so a second `Ctrl+C` interrupts (the smart-copy contract),
+- works on plain-HTTP LAN installs through `_copyText`'s `execCommand` fallback,
+- does not depend on how each browser treats a copy command issued while an empty textarea has focus.
+
+### 3.4 Why no new app setting
+
+Per-shortcut enable/disable and rebinding already exist in App Settings -> Shortcuts and are driven by the registry. A user who wants "Ctrl+C is always interrupt" unchecks one box. Adding a `terminalSmartCopy` setting would duplicate that and would drag in the per-device vs synced decision (`displayKeys` + `.strict()` `SettingsUpdateSchema`) for no gain.
+
+## 4. Code changes, file by file
+
+### 4.1 `src/web/public/app.js`, registry entry
+
+Add to `DEFAULT_SHORTCUTS` (after the `clear-terminal` entry, ~line 351) so the Terminal group stays together:
+
+```js
+{
+  id: 'copy-selection',
+  group: 'Terminal',
+  label: 'Copy Selection',
+  bindings: [
+    { modifiers: ['ctrl'], key: 'c' },
+    { modifiers: ['ctrl', 'shift'], key: 'C' },
+  ],
+  // Dispatched by shouldCopyTerminalSelectionFromShortcut() in terminal-ui.js,
+  // deliberately NOT in SHORTCUT_ACTIONS: the generic capture loop always
+  // preventDefaults, which would cost the user the interrupt key.
+  action: 'copyTerminalSelection',
+},
+```
+
+Match on `key`, not `code`. xterm decides what byte to emit from the produced character, so intercepting the physical `KeyC` on a layout where it does not produce "c" would diverge from what xterm would have sent.
+
+The `action` string is required for App Settings to render the row as configurable (`configurable = !!shortcut.action && Array.isArray(shortcut.bindings)`, `settings-ui.js:2624`). Do **not** add `copyTerminalSelection` to `SHORTCUT_ACTIONS`.
+
+### 4.2 `src/web/public/terminal-ui.js`, the gate
+
+New prototype method, modeled on `shouldOpenCommandPaletteFromShortcut`:
+
+```js
+shouldCopyTerminalSelectionFromShortcut(ev) {
+  if (!ev || ev.type !== 'keydown') return false;          // the handler also runs for keypress/keyup
+  if (!ev.ctrlKey && !ev.metaKey && !ev.altKey) return false;  // hot path: plain typing exits here
+  const registryAvailable =
+    typeof this.getShortcutRegistry === 'function' && typeof this.matchesShortcutEvent === 'function';
+  const entry = registryAvailable
+    ? this.getShortcutRegistry().find((s) => s.id === 'copy-selection')
+    : null;
+  if (entry) return !entry.disabled && this.matchesShortcutEvent(ev, entry);
+  return (ev.key || '').toLowerCase() === 'c' && !ev.altKey; // fallback for isolated harnesses
+}
+```
+
+### 4.3 `src/web/public/terminal-ui.js`, the branch
+
+Inside `attachCustomKeyEventHandler` (`terminal-ui.js:133`), after the command-palette gate and before the `Ctrl+V` branch:
+
+```js
+// Smart copy (#211): with a selection, Ctrl+C copies instead of sending ^C.
+// With no selection it MUST fall through (return true, no preventDefault) or
+// the interrupt key is lost. Ctrl+Shift+C is the explicit chord and never
+// falls through: an "explicit copy" that interrupts the agent is a footgun.
+if (this.shouldCopyTerminalSelectionFromShortcut?.(ev)) {
+  const selection = this.terminal.hasSelection?.() ? this.terminal.getSelection() : '';
+  if (selection) {
+    ev.preventDefault();
+    void this.copyTerminalSelection(selection);
+    return false;
+  }
+  if (ev.shiftKey) {
+    ev.preventDefault();
+    return false;
+  }
+  return true;
+}
+```
+
+`preventDefault()` is explicit because returning `false` alone does not cancel the event (section 2.1), and without it the browser would run its own copy on top of ours.
+
+### 4.4 `src/web/public/terminal-ui.js`, the copy action
+
+```js
+async copyTerminalSelection(text) {
+  const selection = text ?? (this.terminal.hasSelection?.() ? this.terminal.getSelection() : '');
+  if (!selection) return false;
+  const ok = await this._copyText(selection);
+  if (ok) {
+    this.terminal.clearSelection?.();
+    this.showToast('Copied to clipboard', 'success');
+  } else {
+    this.showToast('Failed to copy', 'error');
+  }
+  // _copyText's execCommand fallback focuses a temp textarea; restore the
+  // terminal (this.terminal.focus is the CJK-aware router, not xterm's raw focus).
+  this.terminal.focus();
+  return ok;
+}
+```
+
+The selection text is captured **before** the first `await`, and `navigator.clipboard.writeText` is reached in the same task as the keydown, so user activation still holds.
+
+### 4.5 `src/web/public/i18n.js`
+
+`'Copied to clipboard'` exists. Add `'Failed to copy': '复制失败'` (the error path is new to this surface).
+
+### 4.6 Documentation
+
+| File | Change |
+| --- | --- |
+| `README.md` shortcut table (~line 648) | `\| `Ctrl/Cmd+C` \| Copy selection (interrupts when nothing is selected) \|` and a `Ctrl+Shift+C` row |
+| `src/web/public/index.html` help modal, Terminal section (~line 641) | `<div><kbd>Ctrl</kbd>+<kbd>C</kbd></div><div>Copy Selection / Interrupt</div>` plus the Ctrl+Shift+C row. Keep the existing negative assertion in `help-modal-shortcuts.test.ts` in mind (it forbids `Ctrl+K`, `C` is fine) |
+| `CLAUDE.md` "Keyboard shortcuts" line | add `Ctrl+C` (copy selection, else interrupt) and `Ctrl+Shift+C` |
+| `docs/architecture-invariants.md` -> "Command palette and shortcut registry" | append the invariant: the no-selection path must return `true` without `preventDefault`, the branch is keydown-only, and `copyTerminalSelection` must stay out of `SHORTCUT_ACTIONS` |
+
+The shortcut overlay (`Ctrl+?`) and App Settings -> Shortcuts are registry-driven and pick the entry up with no edit.
+
+## 5. Edge cases and risks
+
+| Case | Handling |
+| --- | --- |
+| Handler also fires for `keypress`/`keyup` | gated on `ev.type === 'keydown'`. xterm's `_keyPress` bails on ctrl combos anyway, so no stray byte |
+| CJK IME composing | the existing `isComposing || keyCode === 229` guard is the first line of the handler and stays first |
+| Local echo overlay has unsent `pendingText` | the copy branch returns before `onData`, so `pendingText`, flushed offsets and the durable input queue are untouched. The no-selection path is byte-identical to today, including the "control char flushes buffered text then sends `0x03`" logic at `terminal-ui.js:895` |
+| Plain HTTP (LAN install) | `_copyText` falls back to `execCommand`, then focus is restored |
+| Clipboard write rejected (permissions policy, no gesture) | error toast, right-click Copy still available |
+| Whitespace-only or empty selection | `getSelection()` empty string is treated as "no selection", so Ctrl+C still interrupts |
+| macOS Cmd+C | registry treats ctrl/meta as interchangeable, so with a selection it takes our path (same visible result as today's native copy), without one it falls through |
+| Chrome/Firefox `Ctrl+Shift+C` is the devtools inspect chord | browser-level and may still toggle devtools, our copy runs regardless. Document as a caveat, `Ctrl+C` is the primary path |
+| Selection in a tab whose TUI owns the mouse (`shell`/`opencode`/`antigravity`) | unchanged, `Shift`+drag selects, then Ctrl+C copies |
+| Web tab (iframe dashboard) focused | xterm handler never runs, browser-native copy inside the iframe |
+| Teammate/subagent terminals (`panels-ui.js:2268`, `onData` wired) | same limitation exists there, out of scope for this PR (section 8) |
+
+## 6. Test plan
+
+New file `test/terminal-copy-selection.test.ts` (node env, `vm` harness in the style of `test/command-palette-ui.test.ts`), covering `shouldCopyTerminalSelectionFromShortcut` in isolation:
+
+1. Ctrl+C keydown -> true, keyup/keypress of the same chord -> false.
+2. Ctrl+Shift+C -> true, plain `c` -> false, Ctrl+K -> false.
+3. Registry entry `disabled: true` -> false for every chord.
+4. Rebound entry (for example Alt+Y) -> true for the rebind, false for Ctrl+C.
+5. Missing registry (harness without `getShortcutRegistry`) -> falls back to the `c` check.
+
+Static assertions appended to `test/keyboard-shortcuts.test.ts` (this suite already pins the xterm-handler chokepoint):
+
+6. `DEFAULT_SHORTCUTS` contains `id: 'copy-selection'` and `SHORTCUT_ACTIONS` does **not** contain `copyTerminalSelection` (the interrupt-safety invariant).
+7. `terminal-ui.js` contains the `shouldCopyTerminalSelectionFromShortcut` branch and a `return true` no-selection fall-through.
+8. README + help modal rows exist (mirrors the existing palette/Alt-nav doc assertions).
+
+`test/help-modal-shortcuts.test.ts`: add `expectShortcut(helpModal, ['Ctrl', 'C'], 'Copy Selection')`.
+
+New browser test `test/terminal-copy-shortcut.test.ts` (Playwright, port **3174**, free per a scan of `test/`), following `test/webgl-fallback.test.ts`: boot `WebServer`, grant `clipboard-read`/`clipboard-write`, `terminal.write()` a known line, `selectLines()`, real `page.keyboard.press('Control+c')`, then assert clipboard content, empty `onData` capture, cleared selection and the toast. Second case: no selection, assert `onData` saw `\u0003` and the clipboard is unchanged.
+Per repo convention, browser suites are excluded from CI, so add the filename to the exclude list in `config/vitest.ci.config.ts` and run it locally.
+
+Regression runs: `npm test -- test/keyboard-shortcuts.test.ts`, `test/help-modal-shortcuts.test.ts`, `test/command-palette-ui.test.ts`, `test/input-send-order.test.ts`, then `npm run test:ci`.
+
+## 7. Manual verification before COM (CLAUDE.md rule)
+
+Against a throwaway session on the live instance (`curl -sk https://localhost:3000/...`, never w1/w2/w3):
+
+1. Select output with the mouse, press Ctrl+C, confirm the toast, paste elsewhere, confirm the agent did not stop.
+2. Press Ctrl+C again with nothing selected, confirm the agent interrupts.
+3. Type a few characters with local echo on (phone or `localEchoEnabled` forced), press Ctrl+C with no selection, confirm buffered text plus interrupt behave as before.
+4. Uncheck the shortcut in App Settings -> Shortcuts, confirm Ctrl+C always interrupts even with a selection.
+5. Rebind it, confirm the new chord copies and Ctrl+C reverts to pure interrupt.
+6. Repeat 1 and 2 in an `opencode` or `shell` tab using Shift+drag to select.
+7. Load over plain HTTP (`--host` LAN or `http://127.0.0.1:<port>`) and confirm the `execCommand` fallback copies and focus returns to the terminal.
+8. Mobile smoke: confirm nothing changed (selection is CSS-disabled, no Ctrl key).
+
+## 8. Out of scope, follow-ups worth filing separately
+
+- **Teammate/subagent terminals** (`panels-ui.js:2268`) have the same blocked-copy problem. One `attachCustomKeyEventHandler` reusing `copyTerminalSelection` would fix them, but it touches a different surface and deserves its own change.
+- **A mobile copy affordance.** Selection is disabled on touch, so phones still cannot copy terminal text. The unreferenced `copyTerminal()` (whole buffer) plus a keyboard-accessory "Copy" button would be the cheapest answer.
+- **Right-click context menu** with Copy/Paste, better discoverability than any chord, but a bigger UI surface.
+- **`copyTerminal()` cleanup**: it uses raw `navigator.clipboard` rather than `_copyText`, so it would fail on plain HTTP if ever wired up.
+
+## 9. PR mechanics
+
+- Branch off `master` (verify with `git branch --show-current`, the tree is shared), stage explicit paths only.
+- Files touched: `src/web/public/app.js`, `src/web/public/terminal-ui.js`, `src/web/public/i18n.js`, `src/web/public/index.html`, `README.md`, `CLAUDE.md`, `docs/architecture-invariants.md`, `docs/terminal-copy-shortcut-plan.md`, three test files, `config/vitest.ci.config.ts`.
+- `index.html`, `app.js` and `terminal-ui.js` are `.prettierignore`d hand-formatted assets, match the surrounding style by hand. `npm run check:public-assets` and `npm run check:frontend-syntax` are the guards.
+- No changeset in this PR: a merged, unconsumed changeset turns the Release workflow red until the next COM, and the COM flow writes release notes covering everything since the last tag (current version is 1.10.0).
+- Close #211 from the PR body.
+
+Rough size: about 60 lines of product code, most of the work is the tests and the four documentation surfaces.

+
+# VM Cases (macOS Virtualization framework), Implementation Plan
+
+## Status
+
+PLANNED, nothing implemented. This is the design + phased execution plan for a native-macOS VM isolation tier for cases ("the VM subsystem"), modeled on Docker cases (`docs/docker-cases-plan.md`). Testbed prerequisite: a macOS 27 host (see Section 8).
+
+**⚠ DESIGN DIRECTION (owner, 2026-07-29): the subsystem is GUI-first.** Users want real macOS desktops, not headless SSH machines. Guests may be macOS (GUI-only in practice) or Linux (GUI or headless). Key decision 3 below carries the full consequences; anything in this doc that reads as "Linux-first / headless-first" predates this and has been revised.
+
+**2026-07-29: Phase 0 substantially validated on the beta testbed; full Apple-stack reference now lives in [`docs/vm-subsystem-apple-stack.md`](vm-subsystem-apple-stack.md)** (API surfaces, beta bugs, our empirical results, and design implications). Plan-relevant corrections from that work: vmnet's topology/port-forwarding APIs are macOS 26 (only the loopback fix is 27); guest provisioning is macOS-guests-only (Linux stays cloud-init, proven working); DiskImageKit has NO flatten/merge, so the `export` subcommand ships the layer chain (or flattens in-guest) instead of flattening; seed ISOs are base-build-time only, never attached at case runtime; per-case EFI variable stores are mandatory; guest health checks read DHCP leases, never serial/ping.
+
+## 1. Context and motivation
+
+WWDC 2026 session 224 ("Expand the Capabilities of your Virtualization App", https://developer.apple.com/videos/play/wwdc2026/224/) shipped the missing pieces for programmatic, fleet-style VM management on macOS:
+
+- **`VZMacGuestProvisioningOptions`**: automated first-boot setup of a macOS guest (user account, auto-login, SSH enabled) with zero interactive setup.
+- **DiskImageKit**: stacked disk images on the Apple Sparse Image Format (ASIF): a read-only base layer plus cheap per-VM cache/overlay layers. Direct analog of Docker image layers + writable container layer.
+- **vmnet framework**: custom network topologies and port forwarding from the host process.
+- **`VZCustomVirtioDevice`**: custom low-latency host<->guest channels (Linux guests).
+- **AccessoryAccess**: USB passthrough (not relevant to Codeman, out of scope).
+
+Codeman's isolation story today is Docker cases. On macOS, Docker means Docker Desktop / a Linux VM anyway, with weaker fidelity and a heavyweight dependency. The Virtualization framework gives hardware-virtualized per-case sandboxes natively, with a layered-image story that mirrors what `scripts/build-agent-image.mjs` does for Docker. This is the premium native-macOS tier ON TOP of Docker cases, never a replacement (Docker remains the cross-platform story; the Linux prod box cannot use any of this).
+
+## 2. Platform reality (hard constraints)
+
+| Constraint                | Detail                                                                                                                                              |
+| ------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
+| Host OS                   | macOS 27 "Golden Gate" required for the new APIs (dev beta since 2026-06-08, public beta since 2026-07-13, GA expected fall 2026)                    |
+| Host hardware             | Apple Silicon only (macOS 27 dropped Intel). Testbed: the owner's dedicated MacBook (Section 8); the M4 Mac mini (macOS 26.4, runs the second Codeman install) stays on stable + untouched |
+| Guest provisioning        | `VZMacGuestProvisioningOptions` needs macOS 27 on BOTH host and guest. Linux guests provision via cloud-init instead                                 |
+| macOS guest concurrency   | **Hard kernel cap: 2 concurrent macOS VMs per host. MEASURED on 27 beta 4 (2026-07-29), not inferred**: the 3rd VM is refused instantly with `VZErrorDomain` code 6 while 39% of RAM is free, so more hardware does NOT raise it. Since macOS GUI guests are the headline use case, this is a real product capacity limit to schedule around and surface in the UI. Linux guests are uncapped (resource-bound only) |
+| Language                  | Virtualization framework is Swift/ObjC only; Node cannot call it. Requires a Swift helper binary (Key decision 2)                                    |
+| Entitlement               | Host process needs `com.apple.security.virtualization`. Fine for a locally built dev binary; distribution needs signing thought (Section 9)          |
+| Nested virtualization     | Linux-guest-only on M3+. A macOS 27 VM cannot dependably host its own guests, so the host-side APIs must be tested on bare-metal 27 (dual-boot)      |
+| CI                        | Cannot run in CI (needs beta macOS on Apple Silicon). Same answer as tmux/docker: no-op all VM IO under `VITEST`, unit-test the pure parts            |
+
+## 3. Goal and user stories
+
+Add "VM cases" to Codeman: a case can point at a per-case virtual machine on a macOS host, and any CLI backend runs inside it over the existing remote-SSH session machinery. A LOCATION OVERLAY on cases, exactly like remote-SSH and Docker cases, NEVER a sixth `SessionMode`.
+
+- As a Mac user, I link a case to a VM so an autonomous run executes behind a hardware virtualization boundary (stronger than Docker's shared kernel) while file viewing, transcripts, and hooks keep working.
+- Per-case VMs are instant and cheap: a shared provisioned base image plus a per-case overlay, not a full image copy per case.
+- Killing a session kills only its in-guest tmux; the VM stays up while sibling sessions remain; case delete tears the VM down.
+- I export a case's VM overlay as a portable artifact (mirror of `docker-exports/`), secrets excluded.
+- On a non-mac host, or a Mac without the helper, the feature is invisible: zero UI, zero probes, zero errors.
+
+Non-goals for the MVP: USB passthrough, custom Virtio channels (Phase 3 candidate), macOS-guest fleets (capped at 2 anyway), Kubernetes-style orchestration, Intel Macs.
+
+## 4. Architecture
+
+```
+Codeman (Node, unchanged session layer)
+  |  JSON over stdout (same pattern as shelling out to docker/tmux)
+  v
+codeman-vm  (Swift package: CLI + per-VM GUI runner app in the console session)
+  |  Virtualization / DiskImageKit / vmnet
+  v
+per-case VM (macOS or Linux)
+      |-- GUI mode: VZVirtualMachineView in a window  --> guest screen sharing --> browser (noVNC)
+      |-- shell:    SSH on vmnet IP                   --> existing remote-SSH tmux machinery
+      ^ VirtioFS: host case dir mounted at the SAME absolute path
+```
+
+Note the runner is a **GUI app in the console user's session**, not a detached daemon: a daemon-launched VM cannot render, which is fatal for macOS guests and for Linux desktop cases.
+
+### Key decision 1: location overlay, not a mode
+
+Identical reasoning to Docker/remote-SSH (see CLAUDE.md): the session layer, respawn, Ralph, recovery, and quick-start plumbing all stay untouched. `SessionMode` stays five-valued. State mirrors the Docker pair: `~/.codeman/vm-hosts.json` + `vm-cases.json`, new `src/vm-hosts.ts` with the storage + pure helpers split.
+
+### Key decision 2: Swift helper CLI (`codeman-vm`)
+
+The framework is Swift-only, so all VM work lives in a SwiftPM package (`packages/codeman-vm/`), a CLI with a stable JSON contract:
+
+- `create-base --guest linux|macos`: build the shared base image. Linux: boot an arm64 cloud image with EFI + cloud-init, install Node 22 + tmux + the four CLIs (same inventory as `docker/agent.Dockerfile`), seal as base ASIF. macOS: IPSW restore + `VZMacGuestProvisioningOptions` (agent user, SSH on), then **desktop-readiness baking**, which is mandatory for GUI guests: suppress the per-user first-login assistant (`com.apple.SetupAssistant` keys + the User Template), enable auto-login (`autoLoginUser` + `/etc/kcpassword`), disable screensaver/lock/display-sleep, and set a static wallpaper (animated "aerials" wallpaper is unusable over remote display). ⚠ Use RAW (not ASIF) for macOS guest disks until the beta's macOS-guest space-reclamation bug is fixed.
+- `create <case>`: DiskImageKit stacked image: shared read-only base + fresh per-case overlay. Near-instant, space-efficient.
+- `start <case>` / `stop` / `status` / `ip`: lifecycle + vmnet NAT; `ip` reports the guest SSH endpoint.
+- `export <case>` / `import`: flatten overlay + workspace tar + manifest, credentials excluded (mirror of docker-export).
+
+A VM dies with its owning process, so `start` spawns a DETACHED per-VM runner process (analog of the detached `scripts/self-update.sh` trick) rather than a monolithic daemon; `status` talks to it over a unix socket in the instance data dir (`dataPath()`, never a hardcoded `~/.codeman` path).
+
+### Key decision 3: multi-guest, and GUI is a first-class mode (REVISED 2026-07-29 by the repo owner)
+
+The subsystem supports both macOS and Linux guests, and a guest runs in one of two **display modes**:
+
+| | macOS guest | Linux guest |
+| --- | --- | --- |
+| **GUI mode** | **the point of the feature**; a real macOS desktop. Mandatory: nothing renders without an attached `VZVirtualMachineView` in an unlocked host session | supported (EFI + virtio-gpu framebuffer) for desktop Linux cases |
+| **Headless mode** | not offered: a macOS guest with no view renders nothing, so a "headless macOS desktop" is a contradiction. SSH-only macOS is possible but is not what this feature is for | supported and cheap; the natural mode for agent/CI work, driven over SSH |
+
+Consequences that flow from GUI being first-class:
+- VM processes are **GUI apps in the console user's session** (LaunchAgent / `launchctl asuser`), never daemons. A daemon-launched VM cannot render.
+- **The host is part of the product surface**: it must auto-login, never lock, never sleep, and keep a live WindowServer. Host lock == every VM's screen goes black, so the screen lock is effectively a global kill switch for every VM display on the machine. The product must own these host settings rather than treat them as user preference.
+- **FileVault conflicts with unattended GUI hosting** and the trade-off must be a deliberate choice: FileVault disables auto-login, so a full-disk-encrypted host needs a human at a keyboard (or a remote screen-sharing session) after every reboot before any VM can render. Options are (a) FileVault on, accept manual login per boot, (b) FileVault off on a dedicated VM host so it boots straight into a rendering session, or (c) FileVault on plus a remote-unlock runbook. Codeman should detect the state and tell the user which one they are in instead of silently serving black screens.
+- **Guests must be desktop-ready, not just booted**: auto-login, no screensaver/lock, and the per-user first-login assistant pre-suppressed at base-image time (`com.apple.SetupAssistant` keys, plus the User Template so later accounts inherit it). Otherwise the user connects to a login prompt or a setup wizard, which is exactly what happened during the first hands-on run.
+- **Capacity is capped for macOS**: at most 2 concurrent macOS VMs per host, confirmed by our own test on 27 beta 4 (3rd refused with `VZErrorDomain` 6 at 39% free RAM; it is a kernel quota, so bigger hardware does not help). Scheduling must queue or evict beyond 2, the UI must explain why, and the scheduler should tolerate the acknowledged slot-leak bug (a slot occupied with nothing running, host-reboot to clear). Linux guests are uncapped and bounded only by host resources, which is the lever for scaling case counts on one machine.
+- **Access is via the guest's own screen**, viewable in a browser through the noVNC chain (see `docs/vm-subsystem-apple-stack.md` §8), so no client-version or client-install requirements land on the user.
+
+Provisioning per guest type: `VZMacGuestProvisioningOptions` for macOS (needs 27-on-27, first-boot-only, and does NOT skip the per-user wizard), cloud-init NoCloud seed ISO for Linux (proven working).
+
+### Key decision 3b: the GUI VM host profile, and supervision that catches black screens
+
+GUI hosting only works if the host is configured for it and supervised. This profile was derived the hard way on the testbed (prototyped there 2026-07-30) and should be what `codeman-vm` installs and verifies:
+
+**Host profile** (the product should own these, not leave them to preference):
+1. **No login barrier.** Either FileVault off + auto-login (a dedicated VM host boots straight into a rendering session, fully unattended), or FileVault on and remote reboots done with `sudo fdesetup authrestart`, where the pre-boot unlock *is* the login so the machine returns already logged in with encryption intact. **`authrestart` is VERIFIED on the testbed (2026-07-30): the host rebooted remotely and came back with a live logged-in console session, FileVault still enabled, no password prompt** — this is the recommended pattern for an encrypted GUI VM host. Plain reboots on a FileVault host always need a human, so Codeman should detect that combination and warn instead of serving black screens.
+2. **Never lock**: lock policy off (needs the account password, so it is a setup step, not a scriptable one) plus `caffeinate -d -i -m -u` re-armed per session.
+3. **Never sleep**: `pmset -a sleep 0 displaysleep 0 disablesleep 1`; a physical display is NOT required (a lid-closed laptop renders fine, only an unlocked session matters). Note OS updates reset these.
+4. **Session-independent control plane**: run VPN/remote access as a system service, never a session app, and keep the access chain (forwards, VNC proxies, web endpoints) in LaunchDaemons so a session restart cannot sever operator access.
+
+**Supervision** must be a **root LaunchDaemon**, not a user LaunchAgent. This is the load-bearing detail: a user agent cannot launch a GUI app into the Aqua session, so its restart attempts fail *silently* (the child dies instantly, leaving an empty log while the supervisor cheerfully reports success). A root daemon can, via `launchctl asuser <uid> sudo -u <user> …`, and those launches persist. Prototyped and verified on the testbed 2026-07-30; a working supervisor runs on a short interval and:
+
+- Restarts the runner when the process is gone **or when its log shows `WindowServer event port death`**, which means it is permanently blind while still looking alive.
+- Defers restarts while the console is at the login window, and launches into whichever session actually exists (resolve the console user with `stat -f %Su /dev/console`, never a hardcoded one).
+- Re-points the guest port-forward whenever the guest's NAT lease changes, which happens on **every guest boot** under plain NAT. A vmnet DHCP reservation for a stable per-case IP is the better long-term answer.
+- **Re-applies host power settings**, because `pmset -a disablesleep 1` does NOT survive a reboot (caught on the supervisor's first run after a real reboot) and OS updates reset it too.
+- Re-arms the keep-awake helper, which dies with its session.
+- Ideally also samples the guest framebuffer for non-black content, since a black screen is the one symptom common to every failure mode here.
+
+`pgrep` alone is worthless for health: every failure mode in this session presented as a healthy process.
+
+### Key decision 4: sessions ride the existing remote-SSH machinery
+
+A provisioned guest is literally an SSH host on a vmnet IP. Session launch = the remote-SSH flow with the host swapped in: durable remote `tmux -L codeman-remote`, session names failing `SAFE_MUX_NAME_PATTERN` on purpose, EVERY ssh command line through `buildSshConnectionArgs()` (command-injection invariant), run flows through `POST /api/quick-start` (never `POST /api/sessions`, which stat-validates `workingDir` locally). What is genuinely new is only lifecycle (create/start/stop/export) and the vm-hosts/vm-cases overlay state.
+
+### Key decision 5: workspace via VirtioFS at the same absolute path
+
+Mirror the Docker bind-mount invariant: the case workspace is a real host directory shared into the guest via VirtioFS and mounted at the SAME absolute path. That keeps file-routes/watchers on real host bytes and makes the in-guest transcript projHash match the host. Without this, transcripts/attachments/file viewer all silently degrade.
+
+### Key decision 6: credentials seeded, hooks bridged
+
+- Credentials are SEEDED (read-only share, copied into the guest once at create), never shared read-write, and excluded from exports: byte-for-byte the Docker cases rule and rationale.
+- Hooks: on the loopback-only prod bind a guest cannot reach `127.0.0.1:3000`. Mirror `CODEMAN_DOCKER_BRIDGE_HOOKS` with a `CODEMAN_VM_BRIDGE_HOOKS` opt-in listener on the vmnet gateway IP; otherwise idle detection falls back to output-based, same as Docker.
+
+### Key decision 7: drift and teardown copy Docker semantics verbatim
+
+Config hash label on the VM (guest type, cpu/mem, share list); a drifted launch is REFUSED, never silently launched stale. One VM per case shared by all sessions; session kill = in-guest tmux kill only; case delete = stop + remove overlay; instance-scoped boot reaper for orphaned runner processes.
+
+## 5. Implementation phases
+
+**Phase 0, testbed (no repo code):** dedicated MacBook on the macOS 27 beta, remotely accessible over the tailnet (setup protocol in Section 8), Xcode 27 beta, then a throwaway Swift script proving the loop: create base -> overlay -> boot -> ssh in. This validates 80% of the design before any Codeman code.
+
+**Phase 1, `codeman-vm` helper:** SwiftPM package, the six subcommands above, JSON contract doc, detached runner + unix-socket status, Linux base image build. Deliverable is testable entirely without Codeman.
+
+**Phase 2, Codeman integration:** types (`VmHost`/`VmCase`/`SessionVm`), `src/vm-hosts.ts` (+ pure helpers: config hash, arg building, endpoint parsing), Zod schemas, `case-routes` link/unlink + listing, `quick-start` vm branch reusing the remote-SSH launch path, `Session` threading + recovery round-trip, `VITEST` no-op layer, unit tests. Feature-detect: darwin + arm64 + helper binary present, else invisible.
+
+**Phase 3, polish:** export/import UI, frontend Create Case "VM" tab + case-picker labels, SSE `vm:*` events, macOS-guest opt-in with cap surfaced, custom-Virtio input channel exploration, CLAUDE.md Key Pattern + `docs/vm-cases.md` + COM.
+
+## 6. Testing
+
+- Pure helpers unit-tested (ports pattern from `docker-hosts.ts`: 26 tests there, aim similar).
+- All helper-invoking IO no-ops under `VITEST` (the `IS_TEST_MODE` pattern in `tmux-manager.ts`).
+- End-to-end verification happens ON the beta MacBook, per the always-end-to-end rule: real base build, real per-case overlay boot, real quick-start into the guest, workspace round-trip through VirtioFS, session-delete keeps VM up, case-delete removes it.
+- CI never runs the real path; the static guards are type-level + unit-level only.
+
+## 7. Risks
+
+1. **Beta API churn**: everything here targets beta SDKs; symbol/behavior changes are likely before fall GA. Mitigation: Phase 0/1 are throwaway-tolerant; no Codeman-side commitment until the helper contract survives a beta cycle.
+2. **New artifact class**: Codeman ships pure TypeScript today; a Swift binary changes build/distribution (build-on-install via `xcrun swift build` on macs with Xcode CLT? prebuilt signed binary per release?). Needs an owner decision; local dev build is fine for the whole beta period.
+3. **Entitlement/signing**: `com.apple.security.virtualization` is trivial for local dev, real for distribution.
+4. **Adoption gating**: users need macOS 27 + Apple Silicon for months after GA. Docker cases remain the default recommendation; VM cases ship dark (feature-detected) with zero cost to everyone else.
+
+## 8. Beta testbed plan: dedicated MacBook (actionable now)
+
+Testbed is a dedicated MacBook the owner sacrifices to the beta (after a full backup). This supersedes the earlier dual-boot-the-Mini idea (git history has it): a dedicated machine means no OS-switching, no downtime for the Mini's live Codeman, and no FileVault pre-boot headaches.
+
+**Sequencing rule that makes it headless: configure ALL remote access on the CURRENT macOS first, THEN upgrade in place.** An in-place beta upgrade preserves Remote Login, Tailscale, user accounts, and auto-login, so there is no Setup Assistant and no post-install physical step. (A fresh install would boot into GUI-only Setup Assistant with no SSH, which on a headless box is a dead end.)
+
+Confirmed hardware (2026-07-28): MacBook, M3, 16 GB RAM, 256 GB disk with ~100 GB free. Verdict: green. M3 = eligible + nested-virt capable; 16 GB = host + 2-3 concurrent Linux guests (macOS guest = one at a time); 100 GB = fits with discipline: install Xcode 27 beta with the macOS platform only (skipping iOS/watchOS/tvOS simulators saves 15-20 GB), and defer any macOS guest base (~30 GB) to an external SSD or until actually needed. Linux guests + sparse ASIF overlays are the comfortable path.
+
+### Pre-upgrade checklist (owner, physical, once)
+
+1. Full backup (Time Machine or clone); the machine should be considered beta-only afterwards.
+2. Tailscale: install, sign into the tailnet, confirm it appears in `tailscale status` from another node.
+3. System Settings -> General -> Sharing: **Remote Login ON** (SSH) and **Screen Sharing ON** (for the rare GUI-only moments: Xcode license, Apple Account dialogs).
+4. **FileVault stays ON** (owner decision 2026-07-28, security over convenience). Consequences: auto-login is unavailable, but FileVault's pre-boot unlock doubles as login, so an unlocked boot still lands in a live GUI session; planned remote reboots go through `sudo fdesetup authrestart` (unlocks for exactly one restart); an UNPLANNED reboot (beta kernel panic, battery drain) parks the machine at the pre-boot screen, no SSH/Tailscale, until the password is typed physically. If the testbed goes silent, suspect this first. Keep it on AC so the battery absorbs power blips.
+5. Beta enrollment (manual): sign into the Apple Account in System Settings; System Settings -> General -> Software Update -> **Beta Updates** -> select the **macOS 27 Developer Beta** (preferred: framework fixes land weeks earlier than public beta; free since 2023 after accepting the agreement once at developer.apple.com; public-beta alternative: enroll at beta.apple.com). Then run the offered upgrade: plugged in, lid open, trusted network.
+6. Send over: tailnet name/IP, username, and a first-login password (key install + lockdown happens remotely right after).
+
+### Post-upgrade setup (remote, over the tailnet)
+
+1. Verify: `sw_vers` reports 27.x, SSH reachable.
+2. Server-ize the laptop: `sudo pmset -a sleep 0 disksleep 0 disablesleep 1` (lid-closed operation without an external display), `womp 1` (wake on network), `sudo systemsetup -setrestartpowerfailure on`. Keep on AC power.
+3. Install the controlling host's SSH key, then disable password auth.
+4. Xcode 27 beta install (the one step needing the owner's Apple Account sign-in once, doable via Screen Sharing from anywhere); `xcode-select`, license accept, verify `swift --version` + the 27 SDK (`xcrun --show-sdk-version`).
+5. Phase 0 prototype loop, all remote from here: Linux guest base image (no 27-on-27 provisioning dependency), DiskImageKit overlay, boot, vmnet NAT, ssh into the guest, run `claude --version` inside.
+6. Only after that loop works: start Phase 1 in `packages/codeman-vm/`.
+
+## 9. Open decisions (owner)
+
+1. Linux base distro/image for the default guest (proposal: Ubuntu 24.04 arm64 cloud image, matching the docker agent image's userland).
+2. Helper distribution for GA: build-on-install vs prebuilt signed binary vs "bring your own Xcode".
+3. Ship dark behind `CODEMAN_VM_CASES=1` for the first release, or feature-detect only?
+4. Export format parity with docker-exports (one manifest schema for both?).

+
+# The VM Subsystem: Apple Virtualization Stack Reference (macOS 27 "Golden Gate")
+
+"VM subsystem" is the working name for Codeman's native-macOS VM isolation tier and everything under it. This document is the single place for what the Apple stack actually provides, what we have verified ourselves on the beta, and what is known-broken. The Codeman-side design lives in `docs/vm-cases-plan.md`.
+
+**Research method note:** Apple's HTML doc pages are JS-rendered and come back empty to fetchers. The working route is the DocC JSON backend: `https://developer.apple.com/tutorials/data/documentation/<path>.json` (page content) and `https://developer.apple.com/tutorials/data/index/<framework>` (full symbol tree with per-symbol `beta` flags). Everything below marked "Apple docs" was parsed from that backend directly.
+
+## 1. Component map and minimum OS versions
+
+| Component | What it is | Min host OS | Notes |
+| --- | --- | --- | --- |
+| Virtualization.framework core | VMs, EFI/Linux boot, virtio devices, VirtioFS | macOS 11-13 era | Unchanged basics; our prototype uses nothing newer than macOS 13 APIs except the DiskImageKit bridge |
+| **DiskImageKit** | ASIF + raw disk images, layered stacks | **macOS 27** | Swift-only, no ObjC headers. Section 2 |
+| **Guest provisioning** | First-boot account/SSH setup for macOS guests | **macOS 27 host AND guest** | Mac guests only as of beta 4. Section 3 |
+| vmnet topology/port-forward/DHCP APIs | Custom networks, port forwarding | **macOS 26** (NOT 27) | 27 adds exactly one fix: loopback port forwarding. Section 4 |
+| `VZVmnetNetworkDeviceAttachment` | In-process vmnet attach | macOS 26 | |
+| **`VZCustomVirtioDevice`** family | Custom paravirt devices | **macOS 27** | Linux guests only, custom guest driver required. Section 5 |
+| AccessoryAccess (USB passthrough) | USB claim + attach to VMs | macOS 27 | Requires paid-team provisioning profile, Dock app. Out of scope for Codeman. Section 6 |
+
+Corrections to the WWDC-session framing we started with: vmnet's topology family is a macOS 26 story (129 symbols, zero beta-flagged in 27); provisioning does NOT currently extend beyond macOS guests despite the generic-looking `VZGuestProvisioningOptions` base class; DiskImageKit has no attach/mount API at all (it is a file-format library that hands `DiskImage` objects to Virtualization, no `/dev/diskN`, no root needed, no entitlement documented).
+
+## 2. DiskImageKit (macOS 27, Swift-only)
+
+Public framework, `/System/Library/Frameworks/DiskImageKit.framework`. No ObjC headers; the API surface lives in the `.swiftinterface`. Verified present in the CLT 27 beta 4 SDK, and our prototype compiled against it with plain `swiftc` on the first attempt.
+
+### API surface (complete as of beta 4)
+
+```swift
+class DiskImage {
+  convenience init(creating: some DiskImage.CreationConfiguration) throws
+  convenience init(opening: some OpenConfigurationProtocol) throws
+  func appending(any DiskImage.CreationConfiguration & DiskImage.StackableLayer) throws -> any StackedImage
+  func appending(consuming DiskImage) throws -> any StackedImage   // reattach an existing layer; validates parentUUID
+  func truncate(blockCount: Int) throws                            // stacked: affects top layer; does NOT resize guest fs
+  var blockCount, blockSize, format, layerType, layerUUID, parentUUID, openMode, size, url
+}
+protocol StackedImage: DiskImage { var layers: [DiskImage] }
+struct OpenConfiguration { init(url:mode:); Mode = automatic | readOnly | readWrite }
+// CreationConfiguration statics: .asif(url:blockCount:blockSize:), .asifLayer(url:type:), .raw(url:blockCount:)
+// DiskImage.LayerType: .cache | .overlay | .overlay(blockCount:)
+// DiskImage.BlockSize: .bytes512 | .bytes4096
+// Errors: CorruptedImageError, IncompatibleStackingError(reason), InvalidBlockCountError, UnsupportedFormatError
+```
+
+Bridge into Virtualization is a new beta convenience init on the existing attachment class. Note there is no `readOnly:` parameter; read-only-ness comes from each layer's own `openMode`:
+
+```swift
+VZDiskImageStorageDeviceAttachment(diskImage: stack, cachingMode: .automatic, synchronizationMode: .full)
+```
+
+### Stacking rules (Apple docs, verbatim where quoted)
+
+- ASIF works standalone or stacked. "You can only use RAW images as standalone images or as **base** images in stacked configurations." Upper layers are always ASIF.
+- **One cache layer per stack**, any number of overlays conceptually, "shallow stacks perform better" (WWDC 224). No published max-depth guidance.
+- "Layers are processed from bottom (base) to top. The **topmost layer determines the stack's size and receives all writes**." `.overlay(blockCount:)` therefore also grows the virtual disk.
+- UUID chaining: appending sets the child's `parentUUID` to the parent's `layerUUID`. Raw bases have no UUID. "The layer UUID **changes if the layer is written to**", and reattaching a mismatched layer throws `IncompatibleStackingError`. This is the mechanism that makes a shared read-only base safe.
+- Base sharing across multiple VMs is the stated design intent ("can be shared across multiple VMs"), with the WWDC caveat that per-VM auxiliary files (EFI variable store, macOS auxiliary storage) must be duplicated per VM, never shared.
+- **There is no flatten/merge.** An overlay cannot be merged back into its base (confirmed by Howard Oakley's coverage plus an independent hands-on report). Export/move flows must ship the layer chain, or flatten inside a guest (dd to a fresh attached image).
+
+### Known issues and adoption
+
+- **ASIF space reclamation is broken for macOS guests on the beta** (deleted files never return space, survives reboots). Linux guests reclaim correctly on both raw and ASIF via `fstrim -av`. Single detailed field report, unrefuted. Since the VM subsystem targets macOS guests, the practical rule until this is fixed is: back macOS guest disks with RAW, and revisit ASIF stacking for macOS guests each beta (stacking still works, the disks just never shrink).
+- **Zero shipping adopters anywhere.** tart has a design issue with no activity; nobody has published working DiskImageKit code. Everything must be treated as field-untested (and our own testing bears that out, Section 8).
+- Framework binary grew every beta (588 → 598 across betas 1-4); expect churn until GA.
+- Release notes list no DiskImageKit known issues in any beta, which given the above says more about the notes than the framework.
+
+## 3. Guest provisioning (macOS guests only)
+
+```swift
+class VZGuestProvisioningOptions: NSObject { func validate() throws }   // "use one of its subclasses"
+class VZMacGuestProvisioningOptions: VZGuestProvisioningOptions {
+  var fullName, username, password: String
+  var logsInAutomatically: Bool
+  var enablesRemoteLogin: Bool   // SSH
+}
+// Wiring: VZMacOSVirtualMachineStartOptions.guestProvisioningOptions (Mac-typed)
+//         .setGuestProvisioning(_:) throws  (validating setter)
+```
+
+- **Requires macOS 27 on host AND guest.** Older guests **silently ignore** the options (no error).
+- **First boot after restore only.** Cannot reconfigure an already-provisioned VM; property changes after start are no-ops.
+- The base class is forward-looking scaffolding; its only subclass is Mac. A Linux/cloud-init analogue may come later; do not assume it lands in 27.0. For Linux guests, cloud-init NoCloud seed ISOs remain the provisioning path (proven working, Section 8).
+- Field-verified behavior (third-party hands-on, beta 3): provisioned account gets full admin + sudo; Setup Assistant fully skipped; SSH reachable ~48 s after first boot. **Race**: the account is created late in first boot (~T+54 s), after LaunchDaemons start (~T+33 s), so anything at daemon-level must wait for the account to exist.
+- Open Apple-acknowledged bug: provisioned users are invisible to `CSIdentityQueryExecute()` (FB23716201).
+- IPSW acquisition gotcha for automation: `VZMacOSRestoreImage.latestSupported` tracks the latest *release* (returned 26.5.2), not the installed beta; beta IPSWs must be fetched from the seed CDN explicitly.
+
+## 4. vmnet: a macOS 26 feature set, one macOS 27 fix
+
+Everything interesting shipped in macOS 26: `vmnet_network_create`, `vmnet_network_configuration_create`, `..._add_port_forwarding_rule`, `..._add_dhcp_reservation`, subnet/prefix/MTU/external-interface setters, NAT44/NAT66/DHCP/DNS-proxy/RA disables, plus serialization (`vmnet_network_copy_serialization` / `_create_with_serialization`) for handing networks across processes. `VZVmnetNetworkDeviceAttachment` is macOS 26.
+
+macOS 27's only change (beta 4 release notes, verbatim): "The vmnet port forwarding APIs now support port forwarding when communicating over loopback." That closes the old gap where the host could not reach its own forwarded ports via 127.0.0.1 (confirmed working by the original bug reporter). Directly relevant to Codeman's loopback-bound production server talking to per-case guests.
+
+Gotchas:
+- vmnet networks are **not persisted**; they die with the owning process. Persist settings yourself and recreate (or serialize across processes).
+- The `com.apple.vm.networking` entitlement is still restricted ("contact your Apple representative", though DTS says most requests are approved). The plain `VZNATNetworkDeviceAttachment` needs no special entitlement and is what our prototype uses.
+- Ecosystem signal: tart's maintainer is not adopting in-process vmnet (prefers their separate-process softnet), so field testing of these APIs is thin.
+
+## 5. VZCustomVirtioDevice (macOS 27, Linux guests only)
+
+14 new types (`VZCustomVirtioDevice(+Configuration/Delegate/Provider)`, `VZVirtioQueue(+Element)`, `VZVirtioFeatureSet`, shared-memory-region types, `VZGuestMemoryMapping`), wired via `VZVirtualMachineConfiguration.customVirtioDevices`. Mandatory for guest discovery: `deviceID`, `pciClassID`, `pciSubclassID`, `virtioQueueCount`. You must write the Linux guest driver (Virtio spec 1.3/1.4). Threading contract: the framework calls the device/delegate on a serial queue (`deviceQueue`, defaulting to the VM's queue). Zero public adopters. For the VM subsystem this is a Phase 3+ option for a low-latency host-guest channel; SSH over NAT is proven and sufficient for now.
+
+## 6. Signing and entitlements
+
+- **Core loop (VZ + DiskImageKit + provisioning): ad-hoc signing with only `com.apple.security.virtualization` suffices.** Verified by us on beta 4 (plain `codesign --entitlements ... -s -` on a `swiftc` binary) and independently by third parties on beta 3. DiskImageKit documents no entitlement at all.
+- **Over-entitling is the actual trap.** Adding `com.apple.application-identifier`/team-identifier keys without an embedded provisioning profile hangs the process before `main` (watchdog kill); shipping `com.apple.vm.networking` unauthorized gets AMFI SIGKILL at exec (exit 137, no crash report, even for `--version`). Keep the entitlements plist to exactly the one key.
+- **USB passthrough breaks the ad-hoc story**: `com.apple.developer.accessory-access.usb` is profile-restricted (any paid team, no ad-hoc), additionally requires `com.apple.security.device.usb`, and `AAUSBAccessoryManager` presents UI, so it wants a Dock app, not a headless CLI. Out of scope for Codeman.
+- No Xcode required for any of the above: the CLT beta (~500 MB via `softwareupdate`) carries the full macOS 27 SDK including DiskImageKit and compiles/signs everything.
+
+## 7. Ecosystem state (July 2026)
+
+- **tart is now `openai/tart`** (moved from cirruslabs, mid-2026) and **relicensed to FSL-1.1-ALv2** (no longer permissive). Provisioning support shipped in 2.33.0. Old cirruslabs URLs and license assumptions are stale.
+- VirtualBuddy shipped provisioning ("Skip Setup Assistant") in 2.2 betas; had to add account-detail validation and a workaround installer for the cross-version bug below.
+- lima is deliberately waiting for GA before touching macOS 27 APIs.
+- **Code-Hex/vz (Go bindings) is dormant** (no commits since Feb 2026, no macOS 27 APIs), so the entire Go ecosystem (podman-machine, colima) currently has no path to these APIs. Swift is the only realistic binding today, which validates the VM subsystem's Swift-helper design.
+- Useful pattern if ever supporting older SDKs: resolve new classes via `NSClassFromString` at runtime (no link-time dependency), fail gracefully when absent.
+- **Cross-version restore bug**: installing a macOS 27 guest from IPSW on a macOS 26 host fails at 77-78% (`VZErrorDomain 10007`); fixed in 26.6b3 + Xcode 27b4 era, with a nasty MobileDevice.pkg trap (installing it from Xcode 27 beta on a 26 host requires a full macOS reinstall to undo). Not relevant to our 27-host testbed, very relevant to anyone on a 26 host.
+
+## 8. Our empirical results (beta 4, 26A5388g, MacBook Air M3, 2026-07-29)
+
+Prototype tooling, all in `~/vm-lab/` on the testbed, compiled with CLT-only `swiftc` and ad-hoc signed with the single virtualization entitlement:
+
+| Tool | Purpose |
+| --- | --- |
+| `vzboot.swift` | Linux guest: EFI boot + virtio disk/net/entropy + NAT + optional cloud-init seed ISO + serial on stdio |
+| `vzstack.swift` | Same, but boots a DiskImageKit stack (read-only raw base + ASIF overlay) |
+| `vzmac.swift` | macOS guest: `install` (IPSW restore into a bundle) and `run` (boot, `--provision` for first-boot account/SSH) |
+| `vzmacgui.swift` | macOS guest in a real window via `VZVirtualMachineView` (required for the guest to render at all) |
+| `setup-seed.sh` | Builds a cloud-init NoCloud seed ISO with `hdiutil makehybrid` (volume label `cidata`) |
+| `vncproxy.py` | RFB proxy that advertises only security type 2, so version-skewed/browser clients can authenticate |
+| noVNC + `websockify` | Browser access; `websockify --web noVNC-<ver> 0.0.0.0:<port> 127.0.0.1:<proxy>` |
+| `vmwatchdog.sh` + `vmaccess.sh` | Supervision: root LaunchDaemon that restarts a blind/dead runner, re-points the forward, re-applies `pmset`, re-arms keep-awake; plus a keeper for the proxy/web endpoints |
+
+Host-side diagnostics written during this work (in the session scratchpad, not on the testbed): `vnclogin.py` (Apple DH auth + session open, distinguishes "credentials rejected" from "authorized but session refused"), `vncshot.py` (decodes the raw framebuffer to PNG and reports non-black pixel counts, plus optional synthetic wake input), `relay.py` (plain TCP relay used to bridge a tailnet peer to a LAN-only host), `sshpw.py` (pty-driven password SSH for the one-time key bootstrap into a freshly provisioned guest).
+
+### Proven working
+
+1. **Boot**: Debian 12 arm64 cloud images (nocloud and genericcloud variants) boot under `VZEFIBootLoader` + `VZGenericPlatformConfiguration`.
+2. **Networking**: `VZNATNetworkDeviceAttachment` gives the guest a `192.168.64.x` DHCP lease from the host's bootpd (leases visible in `/var/db/dhcpd_leases`, bridge is `bridge100`).
+3. **cloud-init provisioning**: NoCloud seed ISO (built with `hdiutil makehybrid -iso -joliet -default-volume-name cidata`) created a `codeman` user with SSH key + passwordless sudo on first boot; `ssh codeman@<lease-ip>` from the host works with key auth.
+4. **DiskImageKit stack mechanics**: opening a raw base `.readOnly`, appending an ASIF overlay (`ASIFCreationConfiguration.layer(url:type:.overlay)`), attaching via `init(diskImage:)`, and booting it. The overlay received ~44 MB of boot-time writes while the **base file's SHA-256 stayed bit-identical**, which is the write-isolation property the whole per-case design rests on.
+5. **Reattach**: reopening an existing overlay and `appending(consuming:)` onto the same base passes UUID validation.
+6. **macOS guest install (added later the same day)**: `VZMacOSInstaller` restore of the 27.0 IPSW (26A5388g, fetched from the seed CDN via appledb; same build as host) into a sparse 64 GiB raw disk + auxiliary storage: INSTALL-OK on the first attempt, ~25 minutes.
+7. **Headless guest provisioning WORKS**: `VZMacGuestProvisioningOptions` via `setGuestProvisioning` (username, password, `enablesRemoteLogin`, `logsInAutomatically=false`) produced, with zero GUI interaction: an account with full admin (groups include `80(admin)`, `com.apple.access_ssh`), Remote Login on from first boot, port 22 reachable ~140 s after first-boot start, hostname auto-derived from the account ("Codemans-Virtual-Machine"). SSH password auth is on by default, so the bootstrap path is: pty-driven password login once to install `authorized_keys`, key auth thereafter. Note the provisioned account's sudo is NOT passwordless (`echo <pass> | sudo -S ...`), and provisioning is first-boot-only (later boots take no options and just boot).
+8. **Slot-leak bug NOT reproduced on 26A5388g**: a guest-initiated `shutdown -h now` fired `guestDidStop` cleanly and an immediate relaunch started fine (SSH-ready again in ~75 s), so FB22967193 (VM slot leaked on guest-initiated shutdown, host reboot to recover) did not manifest after one cycle. Either fixed in beta 4 or needs more cycles to trigger.
+
+### Unstable / under investigation (beta-quality territory)
+
+Boot reliability degraded over a ~15-VM session on one host boot, ending with reproducible silent hangs (VM process alive, 0% CPU, no DHCP, no ARP, nothing on serial):
+
+- A genericcloud base that had been booted read-write once (cloud-init first boot) subsequently hung on every boot **with the seed ISO still attached**, while booting **without** the seed succeeded, then later runs failed in both configurations. The seed correlation is strong but was observed while host state was already suspect, so it needs a retest from a clean baseline.
+- The first stack-boot "success" that later wedged turned out (via DHCP lease timestamp arithmetic) never to have reached the network at all; its overlay growth was pre-network boot writes.
+- Working hypothesis, matching a class of acknowledged beta bugs (e.g. the VM-slot counter that leaks on guest-initiated shutdown, FB22967193, where only a host reboot recovers): accumulated hypervisor/vmnet state on the host degrades boots. Requires a host reboot + a disciplined retest matrix to confirm.
+
+### Display rendering: the single most important operational finding
+
+**A VZ macOS guest renders nothing unless a `VZVirtualMachineView` is attached AND the host session is actually drawing.** Verified byte-for-byte: the guest's own screen sharing serves an all-zero framebuffer (0 non-black bytes across 400 KB samples, with a sane pixel format: `rmax/gmax/bmax = 255`, shifts 16/8/0), in-guest `screencapture` fails with "could not create image from display", and no `IODisplayWrangler` shows up in the guest's `ioreg`. Three distinct states all produce black:
+
+1. **Headless** (VM run with no view attached).
+2. **View attached, host session locked.** The lock screen suspends drawing and the guest's virtual GPU produces no frames.
+3. **View attached, but the app lost its WindowServer connection** (see the incident below): black permanently until the app is restarted.
+
+**Consequence for the VM subsystem: rendering is a first-class requirement, not an optional extra (owner decision 2026-07-29).** The product serves GUI desktops: mandatory for macOS guests, optional-but-supported for Linux guests (which can also run headless over SSH). Any VM in GUI mode must be launched by an app that attaches a `VZVirtualMachineView`, from inside a host GUI session that is logged in and unlocked. That makes the following non-negotiable parts of the design, not workarounds:
+
+- VMs run as **GUI apps in the console user's session** (launched via a LaunchAgent or `launchctl asuser`), never as daemons.
+- The **host must auto-login and never lock or sleep**; a locked host is equivalent to a powered-off display for every VM on it.
+- The **guest must auto-login, never lock, and have its first-login assistant pre-suppressed**, or the "desktop" a user connects to is a password prompt or a setup wizard.
+- A VM app that loses its WindowServer connection is **permanently blind** and must be restarted; supervision has to detect that, not just check that the process is alive.
+- The **2-concurrent-macOS-VM cap** becomes a real capacity limit for the product, so it must be surfaced in the UI and tested (still untested worldwide as of this writing).
+
+### Incident 2026-07-29: `killall -HUP loginwindow` (never do this on a remote Mac)
+
+Applying a wallpaper change on the testbed with `killall -HUP loginwindow` restarted the host's login session. Three consequences:
+
+1. **The Mac dropped off the tailnet entirely.** Tailscale's App Store build is a GUI app living in the user session, so killing the session killed the VPN; remote access was gone until someone logged in. Recovery came from a second machine on the same LAN: it could still SSH in, and then relay ports back over the tailnet (a plain TCP relay on a tailnet-connected LAN peer is a good out-of-band path worth keeping ready).
+2. **The VM app lost its WindowServer connection** (`HIToolbox: received notification of WindowServer event port death`) while surviving as a process. Every later black screen traced to this, and nothing guest-side could fix it; only restarting the app restored rendering.
+3. The session's `caffeinate` died, so the host resumed auto-locking.
+
+Rule: on a remote Mac, never run session-level commands (`killall -HUP loginwindow`, `pkill -u <user>`, logout, fast user switching). `killall WallpaperAgent` alone is session-safe. Before any such command, enumerate what depends on that session: VPN, VM processes, port forwards, keep-awake helpers.
+
+### Keeping host and guest usable unattended
+
+- **Host**: `caffeinate -d -i -m -u` prevents display sleep but does NOT override the lock policy. "Require password after screen saver begins or display is turned off → Never" must be set in System Settings; it needs the account password, so a passwordless-sudo shell cannot script it, and turning it off does NOT dismiss a lock that is already engaged (one more unlock is always needed). `pmset -a disablesleep 1` keeps a lid-closed laptop awake but **does not survive a reboot**, and OS updates reset it too, so a supervisor should re-apply it rather than assume it sticks.
+- **Rebooting an encrypted host**: use `sudo fdesetup authrestart`. FileVault's pre-boot unlock doubles as the login, so the machine returns with a **live logged-in console session** and encryption intact, no password prompt, and supervision can then bring the VMs back by itself. Verified 2026-07-30. A plain `reboot` parks at the lock screen and blacks out every VM until a human logs in.
+- **Guest**: set `autoLoginUser` plus a valid `/etc/kcpassword` (XOR-obfuscated password file, key `7D 89 52 23 D2 BC DE A3`, payload zero-padded to a multiple of 12). `sysadminctl -autologin` fails with `SACSetAutoLoginPassword error:22` on provisioned accounts, and a fresh guest has no Python, so generate the bytes on the controlling host and copy them in. Then `pmset -a displaysleep 0 sleep 0 disablesleep 1`, `defaults -currentHost write com.apple.screensaver idleTime 0`, `defaults write com.apple.screensaver askForPassword 0`, and `caffeinate` inside the guest. ⚠ `autoLoginUser` was observed being wiped by failed `sysadminctl -autologin` attempts; verify it after each boot until stable.
+- **Wallpaper**: animated "aerials" wallpaper is brutal over VNC. The provider lives in `~/Library/Application Support/com.apple.wallpaper/Store/Index.plist` under several keys (`AllSpacesAndDisplays:Desktop`, `:Idle`, and `SystemDefault:*` which is what the login/lock screen uses). Switch each `Provider` to `com.apple.wallpaper.choice.solid-color` with PlistBuddy and restart `WallpaperAgent`. The login-window copy is cached and only refreshes on a later login cycle.
+
+### Remote GUI/SSH access to a guest (recipe, verified 2026-07-29)
+
+The guest lives on the host-private NAT bridge, so remote access is guest-service + host-forward:
+
+1. **In the macOS guest** (over ssh), use ONE mechanism, fully activated. The reliable form is Remote Management in a single kickstart call:
+   ```
+   sudo .../RemoteManagement/ARDAgent.app/Contents/Resources/kickstart \
+     -activate -configure -access -on \
+     -clientopts -setvnclegacy -vnclegacy yes -setvncpw -vncpw <8-char-pw> \
+     -allowAccessFor -allUsers -privs -all -restart -agent -menu
+   ```
+   ⚠ **Half-configured states authenticate but refuse the session.** Loading `com.apple.screensharing` while Remote Management is deactivated (or vice versa) produces an Apple-client error that names the wrong culprit: *"Screen Sharing is not permitted on <host>. Disable and re-enable Screen Sharing or Remote Management in System Settings"*. A raw-protocol client can still authenticate AND open a framebuffer in that state, so protocol-level tests pass while every Apple client fails. The remedy is exactly what the dialog says, done over ssh: `launchctl unload -w …screensharing.plist`, `kickstart -deactivate -configure -access -off`, `pkill screensharingd`, then the single activate call above.
+   Notes: `launchctl enable system/com.apple.screensharing` fails with "Could not find service" on this build; `load -w` is the plain-Screen-Sharing path if you deliberately want it instead of Remote Management. Apple clients negotiate `RSA-SRP` (auth type 33) and the guest logs `Authentication: SUCCEEDED :: User Name: … :: Type: RSA-SRP` on success, which is the definitive server-side confirmation.
+2. **On the host**: a gateway port-forward makes the guest's 5900 reachable from the whole tailnet without per-client tunnels: self-authorize the host's own key, then `ssh -N -g -L 0.0.0.0:5901:<guest-ip>:5900 <user>@localhost` (nohup'd).
+   ⚠⚠ **NEVER forward on host port 5900.** If the host has Screen Sharing enabled (our testbed does, from the pre-upgrade checklist), launchd already owns 5900 socket-activated. The `ssh -L` bind then fails with "Address already in use" **while the tunnel process keeps running**, so every symptom of success is present (process alive, port answers, real RFB banner) yet **every connection reaches the HOST's login window, not the guest**. This cost us an hour: guest credentials failed against the host's screensharingd, which reads exactly like broken guest auth, and we chased the (real, but irrelevant) provisioned-account identity bug. Diagnostics that would have caught it instantly: `sudo lsof -nP -iTCP:5900 -sTCP:LISTEN` showing `launchd` rather than `ssh`, or the guest's own logs showing NO auth attempts during a failed login. Always use a distinct host port and verify with `lsof` that the forward owns it.
+   ⚠ `-g` binds all interfaces, so the forward is also visible on the host's LAN; the VNC layer still requires the account or VNC password. ⚠ The forward pins the guest IP, which changes per boot under plain NAT; re-point it after a guest reboot (the proper fix is a vmnet DHCP reservation, macOS 26 API, once we move off plain `VZNATNetworkDeviceAttachment`).
+   Verified working: with the forward on 5901, both a provisioned account and a `sysadminctl`-created one authenticate successfully (RFB `SecurityResult` = 0) against the guest. The guest offers security types `[30, 33, 36, 2, 35]`, i.e. Apple DH/SRP **plus classic type 2**, so non-Apple VNC clients work with the legacy password once ARD's `-setvnclegacy` is set. (The host's screensharingd, by contrast, offered no type 2, which is itself a tell that you are talking to the wrong machine.)
+3. **SSH from any tailnet device**: `ssh -J <host-user>@<host> codeman@<guest-ip>` (jump through the host), after adding the connecting machine's key to the guest's `authorized_keys`.
+
+**Client-version incompatibility (macOS 27 servers vs older Screen Sharing clients)**: an older Mac's Screen Sharing client fails Apple's `RSA-SRP` handshake against macOS 27 servers, logging `Authentication: FAILED :: User Name: <user> :: Type: RSA-SRP` server-side, while a macOS 27 client authenticates against the same servers without issue. This was verified against BOTH a macOS 27 guest and a macOS 27 host with the operator's own account, so it is a client-side version skew, not configuration, and no server-side change fixes it. Same family as the documented "macOS 26 host cannot install a 27 guest" bug. Practical workaround: bypass Apple auth entirely with classic VNC auth (security type 2), which macOS offers only when Remote Management legacy VNC is enabled. Two ways to consume it: any third-party VNC client, or a browser via noVNC.
+
+**Browser-based access chain (zero client install, version-proof)**, all hosted on the Mac:
+```
+browser --HTTP/WS--> websockify (+ noVNC static files)
+                       --> type-2-only proxy   # rewrites the server's security-type list to [2]
+                         --> ssh -L forward     # loopback hop; see the Local Network note below
+                           --> guest:5900
+```
+Notes learned the hard way: (a) **never bind the forward on host port 5900** (see the launchd warning above); (b) a Python proxy cannot reach the guest subnet directly because macOS **Local Network privacy** denies headless CLI binaries, surfacing as `No route to host`, so point the proxy at a loopback `ssh -L` forward instead (Apple-signed `ssh` is unaffected); (c) noVNC needs `?resize=scale` or Scaling Mode → Local Scaling, otherwise a Retina host screen (2940x1912) is unusable in a browser window; (d) noVNC speaks security type 2 only, which is exactly why the proxy rewrite is needed.
+
+**Debugging technique that settled all of this**: a ~80-line Python RFB client (scratchpad `vnclogin.py`) that implements Apple DH auth (security type 30) and continues through `ClientInit`/`ServerInit`. It reports the server's `SecurityResult` plus the framebuffer size and desktop name, which separates "credentials rejected" from "authorized but session refused" without any GUI client. Pair it with `log stream --predicate 'process == "screensharingd"'` inside the guest, and drive a REAL Apple client headlessly from the host with `sudo launchctl asuser <uid> sudo -u <user> osascript -e 'tell application "Screen Sharing" to open location "vnc://user:pass@host:port"'`, verifying the result via `lsof -nP -iTCP -a -p <pid>` (an ESTABLISHED socket to the target) since `screencapture` fails on a lid-closed laptop ("could not create image from display"). Tailscale was never implicated: both the raw client and Apple's client work over the tailnet address once the guest service is fully activated.
+
+### Hard-won operational lessons (write these into any tooling)
+
+- **Silent serial is normal, not failure.** Debian's GRUB/kernel log to the graphics console; nothing attaches a getty to hvc0 by default. The reliable boot signal is the DHCP lease (or passive `tcpdump -i bridge100`), never the serial port and never a quick ping (BSD ping's first packet often dies to ARP latency; passive capture showed "dead" guests alive).
+- **DHCP lease entries carry truth**: `name=` shows the guest hostname, and the lease timestamps order events; stale entries linger, so compare timestamps before attributing a lease to a boot.
+- **Never boot a base image read-write.** Every RW boot mutates it (dhclient lease cache, journal, cloud-init state) and destroys experiment reproducibility, exactly why the production design only ever boots bases under overlays. Provision INTO the base once at base-build time, or provision per-case overlays with the seed, then detach the seed.
+- **A killed SSH client does not kill a remote `nohup`'d VM**, and the survivor holds the EFI variable store lock: "The EFI variable store is already in use" (`VZErrorDomain 50002`) means a zombie VM process, `pkill` it.
+- **EFI variable stores are per-VM state.** Fresh stores boot reliably; reuse across different VM instances is at minimum suspect on this beta (Apple's own guidance for cloned VMs is one store per VM). Cheap policy: one store per case, created with the overlay, deleted with it.
+- **Downloads from cloud.debian.org mirrors truncate silently**; always verify byte count against origin `Content-Length` and resume with `curl -C -`.
+- The remote host's default shell is zsh: `=` -prefixed words (`echo ===`) explode via zsh's `=cmd` expansion; keep separators zsh-safe in automation.
+
+### The 2-concurrent-macOS-VM cap: TESTED AND CONFIRMED on macOS 27 beta 4 (2026-07-29)
+
+We measured it, which as far as we can tell nobody had published for macOS 27. Method: `cp -c -R` the guest bundle (APFS clonefile, instant and **zero additional disk**), regenerate the machine identifier per clone (`VZMacMachineIdentifier()` written to `machine.id`; the hardware model is reused), then launch VMs until one is refused.
+
+Result: VM #1 (8 GB, GUI) and VM #2 (4 GB, headless) ran concurrently without complaint. VM #3 was refused **instantly** at `vm.start`:
+
+```
+VZErrorDomain Code=6 "The maximum supported number of active virtual machines has been reached."
+NSLocalizedFailure = "The number of virtual machines exceeds the limit."
+```
+
+**This is a licensing/kernel quota, not a resource limit**: the refusal came with **39% of system memory free** on a 16 GB host, and adding RAM or CPU cannot raise it. It matches the pre-27 behavior (`hv_apple_isa_vm_quota`), so nothing changed in 27 despite the framework's other additions. Linux guests are unaffected and are bounded only by host resources.
+
+Design consequences: macOS-guest capacity per host is **hard-capped at 2**, so a GUI-macOS-per-case product must schedule around it (queue, evict idle VMs, or scale across hosts) and surface it in the UI. Also relevant: the acknowledged slot-leak bug (a guest-initiated shutdown failing to release a slot, recoverable only by host reboot) is far more damaging under a cap of 2 than it sounds; we did not reproduce it on beta 4, but any scheduler should treat "slot appears used but nothing is running" as a real state.
+
+### Not yet tested
+- Cache layers (`LayerType.cache`), `.overlay(blockCount:)` disk growth, stack depth performance, VirtioFS + stack combination, `truncate`, ASIF disks for macOS guests (raw used so far; ASIF has the reclamation bug).
+- One more scripting lesson from this session: inner `ssh` calls inside a piped `sh -s` script MUST use `-n`, or they consume the remainder of the script from stdin and it silently never runs.
+
+### Session timeline (what was actually established, 2026-07-29)
+
+Linux path: base image download (with resume, mirrors truncate) → `vzboot` compiles against the beta SDK first try → EFI boot → NAT DHCP lease → cloud-init seed provisions a user with the host's SSH key → `ssh` into the guest works → DiskImageKit stack boots with an ASIF overlay taking all writes while the base stays SHA-identical. Later Linux boots became unreliable on an un-rebooted host (silent hangs, 0% CPU, no DHCP); a clean-baseline retest is still pending.
+
+macOS path: seed-CDN IPSW (matched to the host build) → `VZMacOSInstaller` restore, ~25 min, first try → first boot with `VZMacGuestProvisioningOptions` creates an admin account with Remote Login on, no interaction needed, SSH reachable ~140 s later → key bootstrap over a one-time password login → guest shutdown/relaunch clean (the slot-leak bug did not reproduce) → GUI access fought through a port collision, a client-version incompatibility, the rendering dependency, and a self-inflicted session kill, ending with a browser-based path plus a guest hardened to auto-login and never lock.
+
+**Lifecycle verified (stop → start), 2026-07-30**: an in-guest `shutdown -h now` fires `guestDidStop` and the runner app exits on its own; relaunching from the same bundle boots the guest in ~2 minutes straight into an auto-logged-in desktop, and the VM slot is released cleanly (an immediate restart works, so the slot-leak bug did not bite). Two operational notes: the guest takes a **new NAT lease on every boot**, so any port-forward must be re-pointed (or use a vmnet DHCP reservation), and a host reboot resets `pmset -a disablesleep`.
+
+⚠ **Provisioning does NOT skip the per-user first-login assistant.** `VZMacGuestProvisioningOptions` skips the initial Setup Assistant (account creation, region, Apple Account) so the machine is immediately reachable, but the first time anyone actually logs into a desktop, macOS still presents its per-user wizard (Apple Intelligence, Siri, privacy, appearance, Touch ID). The operator hit exactly this. For a GUI-first product this MUST be pre-suppressed during base-image creation by writing `com.apple.SetupAssistant` keys for every account that will log in, and into `/System/Library/User Template/English.lproj/Library/Preferences/` so accounts created later inherit it.
+
+⚠ **A partial key list is worse than none**, because the wizard simply shows the panes you missed and the operator has to click through them again after every fresh login (we hit this twice). The set that finally silenced macOS 27 beta 4: `DidSeeCloudSetup`, `DidSeeSiriSetup`, `DidSeePrivacy`, `DidSeeAppearanceSetup`, `DidSeeTouchIDSetup`, `DidSeeAvatarSetup`, `DidSeeScreenTime`, `DidSeeApplePaySetup`, `DidSeeSafariImport`, `DidSeeAccessibility`, **`DidSeeActivationLock`, `DidSeeAppStore`, `DidSeeLockdownMode`** (the three easy to miss), plus the Express-Settings flags **`SkipExpressSettingsUpdating`** and **`SkipFirstLoginOptimization`**, and the version markers `LastSeenCloudProductVersion` / `LastSeenBuddyBuildVersion` / `PreviousSystemVersion` / `PreviousBuildVersion` matching the guest build. Verify afterwards by reading the domain back and checking that no `DidSee*` key is still `0`. Note these keys change between macOS releases, so base-image creation should re-verify per OS version rather than trust a hardcoded list.
+
+## 9. Design implications for Codeman's VM subsystem
+
+0. **GUI is a first-class mode, and for macOS guests it is the whole point (owner decision, 2026-07-29).** The subsystem serves real desktops, not only headless SSH boxes. macOS guests are GUI-only in practice (nothing renders without an attached view). Linux guests are supported in BOTH modes: GUI when the case wants a desktop, headless-over-SSH when it wants a cheap agent sandbox. The costs of the GUI path are in §8 "Display rendering": VMs as GUI apps in a live session, a host that never locks, guests that auto-login with their first-login wizard pre-suppressed, and the macOS concurrency cap as a real capacity limit.
+1. **The macOS-specific liabilities are accepted costs, not reasons to avoid macOS guests**: provisioning is macOS-only and first-boot-only, ASIF space reclamation is broken for macOS guests on the beta (use RAW disks for macOS guests until fixed), and the 2-VM cap applies. Plan around each: RAW-backed macOS disks, provisioning baked into base-image creation, and capacity limits surfaced in the UI.
+2. **Base immutability is not just hygiene, it is load-bearing**: DiskImageKit's UUID invalidation plus our sha-stability proof make a read-only shared base per image-generation the core artifact. Bases are built once (seed attached), then only ever opened `.readOnly` under per-case overlays.
+3. **Seed ISOs are a base-build-time tool only.** Never attach a seed to a routine case boot (correlated with boot hangs on the beta, and semantically wrong anyway since cloud-init already ran).
+4. **Per-case files**: overlay ASIF + EFI variable store live and die together with the case.
+5. **Export = ship the layer chain** (base ref + overlay + manifest), not flatten; there is no flatten API. In-guest `dd` to a fresh image is the fallback for a true single-file export.
+6. **Health checking must be lease/API based**, not serial/ping based, and Codeman's `codeman-vm status` should read `/var/db/dhcpd_leases` (or use vmnet DHCP reservations for deterministic per-case IPs, a macOS 26 API).
+7. **Run `fstrim` periodically in Linux guests** (or mount with discard) so overlays stay sparse.
+8. **Entitlements plist stays minimal** (exactly `com.apple.security.virtualization`) to dodge the AMFI/watchdog traps.
+9. **Expect beta churn**: pin findings to build numbers (this doc: 26A5388g) and retest each beta; the framework binaries changed every beta so far.
+10. **A macOS guest is only "ready" when its desktop is ready**, which is a stricter bar than "the VM booted". Readiness means: VM app running with a live WindowServer connection, guest auto-logged-in (not at a login or lock screen), first-login assistant suppressed, and the guest's screen sharing serving a non-black framebuffer. Health checks should sample the framebuffer for non-black content, because every failure mode in this session (headless run, locked host, dead WindowServer, locked guest, setup wizard) presents as a perfectly healthy-looking process with a black or useless screen.
+10b. **Supervision must run as a root LaunchDaemon.** A user LaunchAgent cannot launch a GUI app into the Aqua session; its restarts fail silently (child dies instantly, empty log, supervisor reports success). Root + `launchctl asuser <uid> sudo -u <user> …` works and the launched process persists. This bit us on the first supervisor implementation and is easy to repeat.
+
+11. **Remote-access plumbing belongs in the helper CLI, not in ad-hoc shell**: a `codeman-vm` implementation should own port selection (never 5900), forward lifecycle across guest IP changes (or better, vmnet DHCP reservations for stable per-case IPs), and a documented browser path, because every failure in this session came from hand-rolled plumbing rather than from the Virtualization APIs themselves.
+12. **Never let control-plane connectivity depend on a GUI session** on a remote Mac host: prefer a Tailscale system service over the App Store app, and keep a LAN-adjacent peer able to relay as an out-of-band recovery path.

+# Web tabs: two fixes (planned + implemented 2026-07-28)
+
+Both found against the saved dashboard
+`https://<your-host>.<your-tailnet>.ts.net:4000` (Bio-Hacking-Dashboard).
+Kept because the root-cause analysis of the second one is not obvious from the
+resulting diff.
+
+Status: **both implemented and verified end-to-end.** The one deliberate
+non-change is recorded at the bottom.
+
+---
+
+## Bug 1: saved URLs could not be deleted from the Run dropdown
+
+### What happened
+
+The "Web / URL" section of the Run dropdown listed every saved dashboard as a
+single clickable row whose only action was "open". Deleting required opening the
+dashboard as a tab, clicking the tab's gear, then Delete in the modal, so a URL
+you no longer wanted open at all could not be removed without first opening it.
+
+### What shipped
+
+- `renderWebviewMenuItems()` (`src/web/public/webview-tabs.js`) now renders each
+  saved URL as a `.run-mode-row--web` flex row: the open button, a gear
+  (`showWebviewModal`), and an `x` (`deleteWebviewById`). Nested buttons are
+  invalid HTML, hence the wrapper rather than a button inside a button.
+- `deleteWebview()` split into the modal entry point, the new row entry point
+  `deleteWebviewById(id)`, and the shared `_confirmAndDeleteWebview(id)`.
+- Both side buttons call `event.stopPropagation()` so the click does not also
+  open the dashboard.
+- The dropdown's outside-click handler (`session-ui.js`) closes when the click
+  target is not inside `#runModeMenu`, and the row is gone by the time the delete
+  resolves, so `deleteWebviewById` re-asserts `.active` on the menu. Verified in a
+  browser: deleting one of several URLs leaves you looking at the rest of the list.
+- CSS in `styles.css` (`.run-mode-row--web`, `.run-mode-row-btn`) plus a larger
+  touch target in `mobile.css`. The side buttons are permanently visible rather
+  than hover-revealed, because this menu is used on touch.
+
+No server change: `DELETE /api/webviews/:id` already existed, owner-scoped, and
+already revoked the capability and broadcast `WebviewChanged`.
+
+---
+
+## Bug 2: images did not load in a proxied dashboard
+
+### Reproduction (before the fix)
+
+```
+CAP=<from POST /api/webviews/<id>/open>
+# A) upstream direct                       -> 200 image/jpeg 118150
+curl -sk "https://<your-host>.<your-tailnet>.ts.net:4000/api/hero?slug=120-minutes-in-nature"
+# B) through the proxy prefix              -> 200 image/jpeg 118150
+curl -sk "https://localhost:3000/webview/$CAP/api/hero?slug=120-minutes-in-nature"
+# C) what the browser ACTUALLY requested   -> 404 {"errorCode":"NOT_FOUND"}
+curl -sk -H "Referer: https://localhost:3000/webview/$CAP/" \
+     "https://localhost:3000/api/hero?slug=120-minutes-in-nature"
+# D) same shape but NOT under /api         -> 200 (referer fallback rescues it)
+curl -sk -H "Referer: https://localhost:3000/webview/$CAP/" "https://localhost:3000/styles.css"
+```
+
+The proxy itself was fine (B). The failure was entirely about which URL the
+browser ended up requesting (C).
+
+### Root cause
+
+The dashboard builds its image markup at runtime with root-absolute URLs:
+`c.innerHTML = '<img class="thumb" src="/api/hero?slug=...">'`, `img.src =
+slideSrc(...)` returning `/api/slide?owner=...`, `/api/story`, `/api/video`, and a
+nested `<iframe src="/api/preview?slug=...">`.
+
+All three rewrite layers missed that shape:
+
+1. `<base href="/webview/<cap>/">` only affects **relative** URLs. A root-absolute
+   `/api/hero` ignores the base path and resolves against Codeman's origin.
+2. `rewriteHtml()` only runs over the **initial HTML document**. This markup is
+   created later by page script. (The static header `<img src="/api/logo">` DID
+   work, having been rewritten at proxy time, which is why only the
+   runtime-injected images were broken.)
+3. `runtimeUrlShim()` patched only `fetch`, `XMLHttpRequest.open`, `WebSocket` and
+   `EventSource`, so the dashboard's **data** loaded while its **pictures** did
+   not.
+
+The safety net was fenced off from `/api` in two places, both deliberate:
+`server.ts`'s not-found handler returns the API-envelope 404 before reaching
+`tryWebviewRefererFallback`, and `middleware/auth.ts` refuses the Referer-form
+auth exemption for `/api/`, `/ws/`, `/q/`.
+
+### What shipped
+
+`runtimeUrlShim()` in `src/web/webview-proxy.ts` now also covers the DOM sinks, so
+a root-absolute `/api/...` request is never emitted in the first place and neither
+security fence had to move:
+
+- `innerHTML` / `outerHTML` / `insertAdjacentHTML` (and `ShadowRoot.innerHTML`),
+- `setAttribute` / `setAttributeNS`,
+- the `src`/`srcset`/`href`/`poster`/`data`/`action` property setters on img,
+  source, media, video poster, script, iframe, embed, track, link, anchor, area,
+  object and form,
+- a `MutationObserver` as a last net for any sink not patched above (it costs one
+  wasted 404 per node, since the browser starts fetching on insert, so it is a net
+  and not the mechanism).
+
+Two details that mattered:
+
+- Every rewrite routes through the existing idempotent `rw()` rather than a blind
+  prefix concat. The first draft used the server-side regex shape and
+  double-prefixed markup that was already proxied (a page re-injecting its own
+  `outerHTML`); the jsdom test caught it.
+- Everything stays inside `try`/`catch` and is marked `__cmrw`, so a double
+  injection cannot wrap an already-wrapped setter, and nothing can throw into a
+  page we do not control.
+
+### Verification
+
+- `test/webview-proxy.test.ts` gained a jsdom `runtimeUrlShim DOM sinks` block:
+  innerHTML, insertAdjacentHTML, property setters, setAttribute, srcset candidate
+  lists, the MutationObserver net via an unpatched sink
+  (`createContextualFragment`), idempotence, re-injected markup, empty `src`, and
+  the pass-throughs (relative, cross-origin, `#hash`, `data:`). 73 tests pass.
+- End-to-end in a real browser against an isolated instance
+  (`CODEMAN_INSTANCE=wvtest`, port 3151), with prod's old build as the negative
+  control:
+
+  | | before (prod, old build) | after (fixed) |
+  | --- | --- | --- |
+  | images found | 693 | 693 |
+  | src under the proxy prefix | 0 | 693 |
+  | in-viewport images decoded | 0 / 23 | 23 / 23 |
+  | sample src | `/api/hero?slug=...` | `/webview/<cap>/api/hero?slug=...` |
+
+  (The dashboard marks thumbs `loading="lazy"`, so only in-viewport images are
+  ever fetched. All 27 proxied image responses returned 200.)
+
+---
+
+## Follow-up (same day): the `/api` referer fallback, done safely
+
+Originally deferred, then implemented on request. Both gates had to move, and the
+auth one is the security-sensitive half: auth runs in `onRequest`, before routing,
+so it cannot tell a real Codeman API route from a 404, and simply dropping the
+`/api` fence would let a page holding a capability forge a `Referer` and reach
+Codeman's **real** API unauthenticated.
+
+What shipped:
+
+- `server.ts`: `tryWebviewRefererFallback` is tried **before** the API-shaped 404.
+  Reaching that handler already proves no route matched, and the relay declines
+  unless the `Referer` carries a live capability, so unknown `/api` paths still
+  get the envelope.
+- `middleware/auth.ts`: the `/api/` prefix refusal is replaced by
+  `matchesRegisteredRoute()`, which refuses the exemption for any path that
+  resolves to a real route. `/ws/` and `/q/` stay refused by prefix.
+
+Two findings that decided the implementation, both established by probing Fastify
+rather than by reading its docs:
+
+- **`hasRoute()` is the wrong tool and would have been a hole.** It matches the
+  registered PATTERN literally, so `hasRoute({url: '/api/sessions/abc'})` returns
+  false against a registered `/api/sessions/:id` and would have handed out an
+  exemption on a live, session-scoped API route. `findRoute()` performs the real
+  radix-tree lookup and is what the fence uses.
+- **`@fastify/static` is mounted at `/`, so it registers a root catch-all that
+  matches every path.** A match on it means "heading for the 404 handler", not
+  "real route", and it is distinguishable because a root catch-all is the only
+  route whose `*` param comes back equal to the whole request path. Without that
+  carve-out the fence would have refused every referer-form request and broken the
+  rescue that already worked.
+
+The fence fails closed, and `test/webview-auth-exemption.test.ts` pins both edges
+(a concrete URL onto a parametric API route stays 401; the dashboard's own
+`/api/...` namespace is served).
+
+### And the CSS gap, which the fallback could NOT close
+
+Testing the fallback against a purpose-built upstream showed the runtime-injected
+stylesheet case is unreachable by any relay: a `<style>` element has no URL of its
+own, so Chromium sends an **empty `Referer`** with the image request it triggers
+and there is nothing to key on. Measured directly:
+
+| sink | Referer the browser sends | fixed by |
+| --- | --- | --- |
+| `url()` in a proxied `.css` | the stylesheet's proxied URL | the referer relay |
+| `url()` in a runtime `<style>` | *empty* | `rwCss()` in the shim |
+
+So the shim also rewrites `url()` inside `<style>` blocks, both when they arrive as
+markup and when a `<style>` node is inserted (via the existing MutationObserver).
+
+The only gap left is self-navigation via `location.href = '/x'`, which cannot be
+patched because `Location.href` is unforgeable.

+# Web Tabs (dashboards as Codeman tabs)
+
+Open any dashboard you run, Grafana, Uptime Kuma, Portainer, a status page on port
+4000, as a tab beside your Claude/Codex/Antigravity sessions. Codeman becomes one mission
+control instead of Codeman plus a pile of browser tabs.
+
+## Using it
+
+1. Click the chevron next to **Run** to expand the dropdown.
+2. Under **Web / URL**, pick **Add dashboard...**
+3. Give it a name and a URL, optionally hit **Test**, then **Save**.
+
+The dashboard opens as a tab immediately, and appears in the Run dropdown from then
+on. Web tabs sit in the same strip as session tabs, continue the same `Alt+1..9`
+numbering, and carry a globe icon so they never read as a running agent.
+
+Closing a tab (the `x`) only closes it. The saved dashboard stays in the dropdown.
+To delete it for good, use the `x` on its **dropdown row** (the tab's own `x` is
+close, not delete). Each dropdown row also has a gear for editing, so a saved URL
+can be changed or removed without opening it first.
+
+Switching tabs does **not** reload a dashboard. Frames stay alive in the background,
+so a dashboard that took a while to authenticate is still there when you come back.
+Past six live frames the least-recently-viewed one is dropped to bound memory
+(`CODEMAN_MAX_LIVE_WEBVIEW_FRAMES`).
+
+## Why dashboards are proxied
+
+A plain `<iframe src="http://your-box:4000">` does not work in the setup Codeman
+actually ships in, for three separate reasons:
+
+| Blocker             | What happens                                                                                   |
+| ------------------- | ---------------------------------------------------------------------------------------------- |
+| **Mixed content**   | Production serves HTTPS (behind `tailscale serve`). Browsers hard-block `http://` iframes on an HTTPS page, with no override, and none at all on iOS Safari. |
+| **Framing refusal** | Grafana, Portainer, Home Assistant and many others send `X-Frame-Options: DENY` or `frame-ancestors 'none'`. |
+| **Codeman's CSP**   | `default-src 'self'` means `frame-src` falls back to `'self'`, so a cross-origin iframe is blocked before it starts. |
+
+Serving the dashboard **through Codeman's own origin** dissolves all three. So by
+default a web tab loads `/webview/<capability>/` on Codeman, and Codeman relays to
+the dashboard: stripping the framing refusal, rewriting redirects, cookies and
+root-absolute URLs, and relaying WebSockets so live panels actually update.
+
+A useful consequence: the dashboard is fetched **from the Codeman server**, so a
+tailnet-only or `localhost`-only dashboard works from any device that can reach
+Codeman, including a phone that is not on the tailnet.
+
+`direct` mode (a plain cross-origin iframe) still exists and is cheaper, but it only
+works for an HTTPS dashboard that permits framing. The **Test** button probes from
+the server and tells you which mode applies.
+
+## The sandbox, and when to turn it off
+
+Because a proxied dashboard is served from Codeman's own address, it is
+*same-origin with Codeman* as far as the browser is concerned. Left unchecked, its
+JavaScript could read the Codeman page and call the API that spawns agents.
+
+So the iframe is sandboxed **without** `allow-same-origin` by default. The page runs
+in an opaque origin: it cannot touch Codeman, and it gets no cookies or
+`localStorage` of its own.
+
+Unchecking **Open sandboxed** grants `allow-same-origin`. Do that only for a
+dashboard you fully trust, and only if you need it, which in practice means a
+dashboard with its own login that stores a session in a cookie or `localStorage`.
+
+Even in trusted mode, Codeman never forwards its own credentials upstream: the
+`Authorization` header and the `codeman_session` cookie are stripped on the way out,
+so `CODEMAN_PASSWORD` cannot leak into a dashboard.
+
+## How the proxy authenticates
+
+A sandboxed iframe is opaque-origin, so every request it makes is cross-site: the
+`SameSite=lax` session cookie is not sent, and writes and WebSocket upgrades arrive
+with `Origin: null`. Cookie auth cannot work.
+
+Instead, opening a dashboard mints a **capability**: 192 bits of entropy in the URL
+path, held in memory only, with a rolling 12-hour TTL, bound to the user who minted
+it, and granting exactly one thing, relaying bytes to that one saved URL. Editing or
+deleting a dashboard revokes it, and a server restart invalidates every outstanding
+capability (tabs re-mint transparently on next click).
+
+## Limits and env vars
+
+| Variable                             | Default | Meaning                                    |
+| ------------------------------------ | ------- | ------------------------------------------ |
+| `CODEMAN_MAX_WEBVIEWS`               | 50      | Saved dashboards per owner                 |
+| `CODEMAN_MAX_LIVE_WEBVIEW_FRAMES`    | 6       | Iframes kept mounted at once               |
+| `CODEMAN_WEBVIEW_CAPABILITY_TTL_MS`  | 12h     | Rolling capability lifetime                |
+| `CODEMAN_WEBVIEW_TIMEOUT_MS`         | 30000   | Upstream request timeout                   |
+| `CODEMAN_WEBVIEW_PROBE_TIMEOUT_MS`   | 8000    | Timeout for the Test button                |
+| `CODEMAN_MAX_WEBVIEW_HTML_BYTES`     | 8MB     | Largest HTML document rewritten            |
+| `CODEMAN_MAX_WEBVIEW_SOCKETS`        | 8       | Concurrent proxied WebSockets per dashboard |
+
+Saved dashboards live in `~/.codeman/webviews.json`. Which tabs you have open is
+per-device (`localStorage`), since that is workspace layout rather than config.
+
+## How a dashboard's own API calls keep working
+
+Worth knowing, because it is where this feature does its least obvious work. Three
+layers cooperate so a dashboard talking to its own backend just works:
+
+1. `<base href>` handles relative URLs in the markup.
+2. Attribute rewriting handles root-absolute `src`/`href`/`action` in the page the
+   proxy serves.
+3. A small injected script rebases URLs built at **runtime**, which the first two
+   cannot see: `fetch('/api/data')` and `new WebSocket('/live')`, but equally
+   `card.innerHTML = '<img src="/api/hero">'`, `img.src = '/api/slide'`, and
+   `url(/img.png)` inside a `<style>` the page injects. That second group is why
+   images are covered too. A dashboard that renders its thumbnails from script
+   would otherwise show all its data and none of its pictures, because `<base>`
+   does not apply to root-absolute URLs and the attribute rewriting only ever saw
+   the initial document.
+4. As a last resort, a request that still lands on Codeman's own root is relayed
+   using its `Referer` to identify the dashboard. This only fires for a request
+   that already missed every Codeman route, and never for one that resolves to a
+   real route, which is what keeps it from being an authentication bypass.
+
+On top of that, the proxy answers those requests with CORS headers. That sounds
+wrong for same-host requests, but a sandboxed iframe has an *opaque* origin, so the
+browser treats every one of its `fetch`/XHR calls as cross-origin even though the
+URL is on Codeman itself. Without those headers, a dashboard renders perfectly and
+then every API call fails, which looks like the dashboard being broken.
+
+## Known limits
+
+- **Exotic loaders.** The layers above cover normal `fetch`/XHR/WebSocket/
+  EventSource, normal markup, the DOM sinks a page uses to build markup at runtime,
+  and `url()` inside stylesheets. Something that constructs requests by an unusual
+  route can still slip through. Symptom: the page renders but a panel stays empty.
+- **Root-absolute `location` navigation.** A dashboard that navigates itself with
+  `location.href = '/login'` escapes the prefix, because `Location.href` is
+  unforgeable and cannot be patched the way the other sinks are. A relative
+  `location.href = 'login'` is fine (`<base>` covers it).
+- **Cross-origin redirects are not followed.** If a dashboard bounces to a different
+  host (an external SSO provider, say), the proxy hands the redirect back unchanged
+  rather than relaying it, because relaying would make this an open proxy. Use
+  **Open in new tab** for those.
+- **Login-protected dashboards need trusted mode**, since a sandboxed frame has no
+  cookie jar. A server-side per-dashboard cookie jar would lift this and is the
+  natural next step if it becomes annoying.
+- **Not a security boundary.** The proxy reaches whatever the Codeman server can
+  reach. That is not an escalation for someone who already commands
+  `--dangerously-skip-permissions` agents, but in multi-user mode it does mean a
+  non-admin user's dashboard is fetched from the server's network position.
+

 # xterm-zerolag-input
 
+## 0.1.8
+
+### Patch Changes
+
+- **Fixed: sessions failed to start on macOS with `Error: posix_spawnp failed.`** (issues #6 and #204)
+
+  `node-pty@1.1.0` publishes its macOS prebuilt helper as `prebuilds/darwin-<arch>/spawn-helper` with mode 0644, i.e. no execute bit. macOS launches every PTY through that helper, so a stock install failed on every session start. The bug is macOS-only: `spawn-helper` is a mac-only gyp target and node-pty ships no Linux prebuild, so Linux always compiles a correctly-permissioned helper from source.
+
+  The previous fix chmodded only `build/Release/spawn-helper`, which on macOS does not exist (the prebuild is used, so node-gyp never runs), and it derived that path from `require.resolve('node-pty')`, landing on `<pkg>/lib/build/Release/...`. It was a no-op on every platform.
+  - New `scripts/fix-node-pty.mjs` (also `npm run fix:node-pty`) chmods every `spawn-helper` it finds, in `build/Release`, `build/Debug` and each `prebuilds/*/`, then verifies the result by actually opening a PTY. A `require()` alone passes on a broken install, because the helper is only touched at spawn time.
+  - `postinstall` no longer force-rebuilds node-pty from source on Node 22+. That step needed Xcode command line tools, cost 30-120s on every install, and deleted the `prebuilds/` tree before compiling, so a Mac without a compiler was left with no working binary at all. A rebuild now happens only when the chmod plus spawn probe still fails, and the prebuilds tree is backed up and restored around it.
+  - New `spawnPtyWithHelperRepair()` (`src/utils/node-pty-repair.ts`) wraps every `pty.spawn()` in `session.ts`, so an install that is already broken repairs itself on the first failed spawn and retries in-process instead of showing a dead session. Unrelated spawn errors are rethrown untouched; a second failure carries the `npm run fix:node-pty` hint.
+  - `scripts/fix-node-pty.mjs` is now in the published `files` list, so global npm installs get the repair too.
+  - Direct-PTY Claude spawns use the resolved absolute binary path (new `getClaudeBinaryPath()`) instead of the bare name `claude`, so a CLI installed outside the server's PATH still launches.
+
+  Verified end to end on macOS 26.4 arm64: a stock `npm i` reproduces `posix_spawnp failed.`, and after the fix the same install spawns a PTY successfully with the prebuilds preserved.
+
+  **Added: phone home screen (session overview)**
+
+  Under 430px the "C" logo now opens a session overview (current sessions, past sessions, spaces) instead of the welcome overlay: on a small screen "which session needs me" beats "how do I start one". Rows resume a session in place, and "New session here" goes through the normal quick-start path so remote and Docker cases keep their routing. Per-device setting `mobileOverviewEnabled` (phones only, default ON) in App Settings. Tablet and desktop are unchanged.
+
+  **Added: guided Tailscale setup in `install.sh`**
+
+  The network-access prompt is now 3-way: Tailscale, LAN, or local-only. The Tailscale path binds loopback and walks through installing Tailscale, logging in, the operator grant, the tailnet HTTPS-certificates toggle, and `tailscale serve --bg <port>`, then verifies the result end to end with curl. That gives HTTPS on a real certificate with no app password and no `0.0.0.0` bind, which is also what PWA install and web push need. `install.sh tailscale` retrofits it onto an existing install, and `CODEMAN_TAILSCALE=1` presets the choice. Serve state is detected from `tailscale serve status --json`; the installer never runs `tailscale serve reset` and never touches serve mappings other than 443 to Codeman's port. README and `docs/security-architecture.md` updated to match.
+
+  **Docs**: replaced a real tailnet hostname with placeholders in `docs/web-tabs-fixes-plan.md`.

+  **xterm-zerolag-input**: npm description and keywords only, no code change.
+
+## 0.1.7
+
+### Patch Changes
+
+- Fix a latent bug where a partial settings PUT silently reset live service state, and trim the `xterm-zerolag-input` README callout.
+  - **`PUT /api/settings` no longer resets watchers on a partial body.** The three `toggleService` calls (subagent watcher, workflow-run watcher, image watcher) read the raw request body with `??` defaults, so every key a caller omitted was treated as "apply the default". A body of just `{statusLineTelemetry:true}` would START the subagent watcher and STOP the workflow and image watchers, undoing the persisted config. They now resolve from `merged` (persisted settings + incoming), the same convention the `tmuxHistoryLimit` branch in that handler already used, so any PUT reconciles services to the effective stored state. Nothing triggered this in practice because every shipped client sends a full settings payload rebuilt from the DOM, but it was a trap for the next partial-update caller.
+  - **Regression test**: `test/routes/system-routes-settings-partial-put.test.ts` (4 cases) pins both directions, omitted keys preserve state and explicit keys still take effect. Verified to fail against the pre-fix handler.
+  - **CLAUDE.md** records the rule under "Adding Features → App setting": anything acting on a setting in that handler must resolve from `merged`, never the request body.
+  - **`xterm-zerolag-input` README**: removed the links line (getcodeman.com / install one-liner / star link) from the Codeman callout above the demo GIF. The callout keeps its links in the heading and body.
+
+## 0.1.6
+
+### Patch Changes
+
+- Plan-usage chip now defaults ON on desktop, plus the reworked `xterm-zerolag-input` README.
+  - **Plan-usage chip defaults ON (desktop).** The `showPlanUsageLimits` chip (live 5-hour and weekly plan usage from the Claude statusline) used to be opt-in and default OFF, so most users never saw it. Desktop now defaults ON; handhelds still default OFF so the phone header stays minimal and the `mobile-header-buttons-policy` guard keeps passing. Devices with an explicitly stored preference keep whatever they chose, so nobody's OFF gets overridden.
+  - **One resolver behind the chip.** Added `planUsageChipEnabled()` in settings-ui.js and routed all three call sites through it: the App Settings checkbox, the chip's visibility, and the create-time `statusLineTelemetry` flag in session-ui.js. Those three had independent `?? false` / `=== true` defaults, and a chip revealed without the telemetry flag renders `—` forever, so a default flip on one site alone would have shipped a permanently empty chip.
+  - **Cron button comment corrected.** The App Settings comment claimed "Cron button defaults ON" while the code, the template (`btn-cron--hidden`) and the CSS all default it OFF. Verified against a fresh browser profile: the button is hidden and its checkbox unchecked out of the box. Comment now matches, and states why the two halves stay consistent.
+  - **Docs.** CLAUDE.md, `docs/architecture-invariants.md` and `docs/usage-limits-display-plan.md` updated for the new default and the single-resolver rule; the stale `styles.css` comment claiming the server strips the chip's hidden class at render was corrected (display is per-device, so the client reveals it).
+  - **`xterm-zerolag-input` README rework** (0.1.5 shipped the content; this republishes with the graphic and promo changes): replaced the misaligned 8-line keystroke-flow diagram with a two-line stock-vs-zerolag contrast, added a Codeman callout above the demo GIF with links to getcodeman.com and the repo, and rewrote the Origin section so it argues the extraction story instead of repeating the promo.
+
+## 0.1.5
+
+### Patch Changes
+
+- Rewrite the `xterm-zerolag-input` package README as a value-first document and correct the drift that had accumulated against the source.
+  - Added the side-by-side phone demo GIF (`docs/images/zerolag-demo-20260728.gif`) as the hero image, referenced by absolute raw URL so it renders on npmjs.com as well as GitHub. The two-phone comparison shows 0ms local echo next to a 600ms-2.7s server echo on the same session.
+  - New "Why this one" comparison table, an explicit list of target use cases (SSH web clients, cloud IDEs, mobile terminals, container consoles), and a bundle-size badge (6.1 kB gzipped, measured from the ESM build).
+  - Corrected the test-count badge from 78 to the actual 175 tests across 5 files, in both the package README and the Published Packages section of the root README.
+  - Removed the stale "Unicode/emoji rendered at single-cell width" limitation. CJK, fullwidth forms and emoji have had double-width rendering and visual-column positioning since the wide-character fix; the honest remaining caveat (per-code-point width summing over-counts ZWJ grapheme clusters) replaces it.
+  - Documented the previously undocumented public `setPrompt()` method for switching prompt strategies at runtime, and the new "Wide characters (CJK, emoji)" integration section covering the optional `Unicode11Addon` path and the built-in range-table fallback.
+  - Documented `backgroundColor: 'transparent'`, corrected the `foregroundColor` default, and updated the grid-alignment math to reflect visual-column positioning rather than character index.
+
+  No source changes, docs only.

-## The Problem
+## The 30-second version
 
-When using xterm.js over a remote connection (SSH web clients, cloud IDEs, mobile terminals), every keystroke takes a full round-trip to the server before appearing on screen. At 100-500ms RTT, typing feels sluggish and unresponsive. Users type blind, make mistakes they can't see, and the experience feels broken.
-
-## The Solution
-
-`xterm-zerolag-input` renders typed characters **immediately** as a pixel-perfect DOM overlay positioned on the terminal's character grid. The overlay covers the terminal canvas at the prompt location, showing characters instantly while the server echo travels back. Once the server responds, the overlay seamlessly disappears and the real terminal text takes over.
+Over a remote connection, xterm.js shows you a character only after it has flown to the server and back. At 100-500ms RTT that reads as broken: you type ahead of the screen, you cannot see your typos, and you start pecking one key at a time to stay in sync.
 
 ```
-Keystroke Flow:
-                                    ┌─── DOM overlay (instant, 0ms)
-User types 'h' ─── onData('h') ───┤
-                                    └─── Your app sends to PTY ──→ Server
-                                                                      │
-Server echoes 'h' ←──────────────────────────────────────────────────┘
-         │                                                  (200-500ms RTT)
-         └──→ terminal.write('h') ──→ overlay.clear()
-              (server output replaces overlay — seamless transition)
+  stock xterm.js   keypress ─────── 300 ms ───────→ character appears
+  with zerolag     keypress → character appears  ·  echo lands later, unseen
 ```
 
-**No changes to your backend needed.** The addon is purely client-side.
+Same keystroke, same link. The only difference is who you wait for: the server, or nobody.
 
-## Origin
+`xterm-zerolag-input` paints your keystrokes **immediately**, as an absolutely-positioned DOM overlay locked to the terminal's character grid. The byte still goes to the PTY exactly as before, so nothing about your shell changes. When the server echo lands 300ms later, the overlay clears and the real terminal text takes over on the same pixels. The handoff is invisible.
 
-This library was extracted from [Codeman](https://github.com/Ark0N/Codeman), mission control for AI coding agents — multi-session management, real-time agent visualization, autonomous respawn loops, and a mobile-first web UI for Claude Code, OpenCode, and Codex. The local echo system was built to make mobile and remote access feel instant, then battle-tested across thousands of hours of real usage. After 3 deep code audits, it was extracted into this standalone library with 78 tests covering every state transition.
+**No backend changes. No protocol. No server support.** It is a client-side addon that never touches the wire.
+
+## Why this one
+
+| | |
+|---|---|
+| **Survives full-screen TUIs** | Ink, blessed, and friends repaint the whole screen constantly. The overlay is a separate DOM layer they cannot reach, so it does not get clobbered. |
+| **Pixel-matched to the canvas** | Each character is its own absolutely-positioned `<span>` at exact cell coordinates, so it does not drift out of the grid like normal DOM text flow. |
+| **Wide characters included** | CJK, fullwidth forms and emoji render double-width and position by visual column, using the terminal's Unicode addon when one is loaded. |
+| **Backspace that actually works** | A three-layer cascade (unsent, in-flight, already on screen) tells you exactly what to forward to the PTY, so editing works through any mix of typed, flushed and tab-completed text. |
+| **You keep control of input** | The addon never hooks `onData` for you. You decide what gets echoed and what gets forwarded, which is what makes char-at-a-time, buffered, and multi-session tab switching all possible. |
+| **Small and self-contained** | 6.1 kB gzipped, zero runtime dependencies, dual CJS/ESM with full type declarations. |
+| **Proven under load** | Extracted from [Codeman](https://getcodeman.com), hardened over thousands of hours of real remote and mobile usage, 175 tests over every state transition. |
+
+Built for anything that puts a terminal behind a network hop: SSH web clients, cloud IDEs, mobile terminals, Kubernetes and container consoles, remote agent dashboards, browser-based dev environments.

+### Wide characters (CJK, emoji)
+
+Wide characters work out of the box: the overlay measures each character's cell width, renders double-width spans for wide ones, and positions later characters by visual column instead of character index. Line wrapping is computed in columns too, so a wrapped Japanese or Chinese line lands on the same cells the server will use.
+
+For exact Unicode 11+ widths, load xterm's Unicode addon and the overlay will defer to it:
+
+```typescript
+import { Unicode11Addon } from '@xterm/addon-unicode11';
+
+terminal.loadAddon(new Unicode11Addon());
+terminal.unicode.activeVersion = '11';
+```
+
+Without it, a built-in range table covers Hangul, Kana, CJK Unified (including Ext A through G), fullwidth forms and the emoji planes.

-## Known Limitations
+## Known limitations
 
-- **Canvas/WebGL font mismatch**: Minor sub-pixel differences possible. Per-character absolute positioning minimizes this.
-- **Unicode/emoji**: Multi-byte characters occupy variable cell widths — rendered at single-cell width, causing misalignment.
-- **Password prompts**: Overlay shows characters that aren't echoed. Call `clear()` when you detect no-echo mode.
-- **Prompt in output**: If `$` appears in command output, prompt detection may find the wrong position. Use regex or custom finder.
+- **Canvas and WebGL font mismatch**: minor sub-pixel differences are still possible. Per-character absolute positioning keeps them small.
+- **Grapheme clusters**: widths are summed per code point, so ZWJ emoji sequences (for example 👨‍👩‍👧) and combining marks can be over-counted. Single-code-point emoji and CJK are correct.
+- **Password prompts**: the overlay will happily show characters the server is not echoing. Call `clear()` when you detect a no-echo prompt.
+- **Prompt characters in output**: if your prompt marker also appears in command output, detection can latch onto the wrong line. Use a regex or a custom finder.

+## Origin
+
+[Codeman](https://getcodeman.com) needed this before anyone else did. A coding agent you drive from your phone over a tunnel is unusable if every keystroke costs a round trip.
+
+So the overlay was built there, ran in production for thousands of hours, and survived three deep code audits before being pulled out into this standalone library with its tests intact. Nothing was reimplemented for the extraction: the engine here is the one Codeman ships.

+ * @fileoverview Repairs node-pty's macOS `spawn-helper` and verifies that a PTY
+ * can really be spawned. Called by `scripts/postinstall.js` on every install and
+ * exposed as `npm run fix:node-pty` for repairing an install after the fact.
+ *
+ * Why this exists (issues #6 and #204):
+ *
+ * node-pty@1.1.0 publishes its macOS prebuilt helper as
+ * `prebuilds/darwin-<arch>/spawn-helper` with mode 0644, i.e. no execute bit.
+ * On macOS node-pty launches every PTY through that helper with posix_spawnp,
+ * which then fails EACCES and surfaces as `Error: posix_spawnp failed.` on every
+ * session start.
+ *
+ * It is macOS-exclusive twice over: `spawn-helper` is an `OS=="mac"` gyp target,
+ * and pty.cc only spawns it under `#if defined(__APPLE__)`. node-pty ships
+ * prebuilds for darwin and win32 only, so Linux always compiles from source
+ * (which produces an executable helper) and never sees the bug.
+ *
+ * The repair is a chmod, NOT a rebuild: the prebuilt binary itself is fine, and
+ * requiring a from-source rebuild would make every macOS install depend on Xcode
+ * command line tools. A rebuild is attempted only when a chmod plus a real spawn
+ * probe still can't get a working PTY, and the prebuilds tree is backed up first
+ * so a failed rebuild can never leave the install worse than it started.

+/**
+ * @fileoverview Entrance animations for the four things that appear when work
+ * starts: session TABS, the main TERMINAL pane a session's CLI runs in, floating
+ * agent WINDOWS, and the CONNECTION LINES tying a window back to its parent tab.
+ * One picker per surface, plus themes that set all four to a matching look.
+ *
+ * Everything is OFF by default (the `legacy` theme), so an untouched install
+ * behaves exactly as it did before this module existed. Opt in via App Settings
+ * → Appearance → Entrance Animations.
+ *
+ * Four constraints shape the design:
+ *
+ * 1. `_fullRenderSessionTabs()` replaces the tab strip's entire innerHTML, and
+ *    `_updateConnectionLinesImmediate()` does `svg.innerHTML = ''` and rebuilds
+ *    every path. Both run constantly while sessions and agents are spawning, so
+ *    an animating tab or line element is DESTROYED mid-flight. Those two are
+ *    therefore tracked by id in `_tabEnterActive` / `_lineEnterActive` and
+ *    re-applied to the fresh element with a NEGATIVE animation-delay, resuming at
+ *    the same offset instead of restarting or snapping to the end. Windows are
+ *    stable DOM and need none of this.
+ * 2. Connection-line geometry comes from `getBoundingClientRect()` on the window.
+ *    A window entrance that starts with a transform would move that rect, so the
+ *    `beam` style (which must hold still while its line draws toward it) animates
+ *    opacity and filter only. Every other style refreshes the lines when it ends.
+ * 3. The terminal pane is ONE shared element, so its entrance is marked at
+ *    session creation but played at selection: a session created in the
+ *    background must not animate the pane the user is currently looking at. Its
+ *    styles are also restricted to transform/opacity/clip-path (see below).
+ * 4. Nothing may animate on page load or reconnect replay. Only ids that pass
+ *    through `markSessionTabEntering()` animate, and `_tabEnterSeen` makes that
+ *    once-per-id even though the POST response and the SSE event both call
+ *    `_onSessionCreated`.
+ *
+ * Styles are selected by `data-tab-anim` / `data-term-anim` / `data-win-anim` /
+ * `data-line-anim` on <html>; the keyframes live in styles.css. `?animlab=1`
+ * opens a floating picker that fakes tabs, a pane replay, a window and a line,
+ * so styles can be compared without spawning real sessions or agents.
+ *
+ * @mixin Extends CodemanApp.prototype via Object.assign
+ * @dependency app.js (tab render pipeline), subagent-windows.js (window + line hooks)
+ * @dependency constants.js (escapeHtml)
+ * @loadorder 12.6 of 16, after webview-tabs.js, before ralph-wizard.js
