+## 1.4.0
+
+### Minor Changes
+
+- Add **Docker session mode**: a case can now run inside an isolated Docker container instead of on the host, with configurable network / resource / credential settings, multiple sessions sharing one per-case container, and one-click export to move a container (toolchain + workspace) to another machine.
+  - Docker is a location overlay on cases (not a new session mode), mirroring the remote-SSH feature: a local tmux pane runs `docker exec -it` into a durable in-container tmux server. The container is scoped to the case (`codeman-case-<name>`), so multiple sessions share it; killing one session never stops the shared container.
+  - New `/api/docker-hosts` CRUD, `/api/cases/docker-link`, and a `/api/quick-start` docker branch. Create Case gains a **Docker** tab. Base image is built locally via `scripts/build-agent-image.mjs` (node + claude/codex/gemini/opencode + tmux, secret-free, arbitrary-uid-writable HOME).
+  - Hardened by default: `--cap-drop ALL`, `--security-opt no-new-privileges`, non-root, `--pids-limit`, `--memory`==`--memory-swap`, `--init`; never `--privileged` or the docker socket. Convenient credential default bind-mounts host `~/.claude` etc. read-write (never captured by `docker commit`); a sealed profile is opt-in.
+  - Two-layer durability: reconnect after a Codeman restart reattaches the same live agent; a container stop/reboot resumes the conversation from the bind-mounted transcript via `--resume`.
+  - Export / import: full-image (`docker commit` + `save` + workspace tar + manifest) or workspace-only, to one portable `.codeman-container.tgz`; import validates checksums, guards path traversal, and re-tags the loaded image into a quarantined namespace. Instance-scoped boot reaper cleans orphaned containers. New `docker:*` SSE events. Docs in `docs/docker-cases.md`.
+  - Robustness: sets `CLAUDE_CODE_TMPDIR` in the container so claude launches regardless of workspace path. In-container hooks require the server to be reachable from the container (documented); on a loopback-only bind, idle detection falls back to output-based.
+
+  Also wire session, away-digest, and cron header-button visibility toggles in App Settings.
+
+## 1.3.5
+
+### Patch Changes
+
+- a842f2d: fix(auth): slide the session cookie so active users aren't logged out
+
+  Re-issue the `codeman_session` cookie on every authenticated request so the
+  browser cookie lifetime tracks the server-side sliding TTL (the session store
+  already uses `refreshOnGet`). Previously the cookie was only set on the Basic
+  Auth path with a fixed 24h lifetime from login, so the browser dropped it
+  mid-use; the next request arrived cookie-less, fell through to Basic Auth and
+  popped the native username/password dialog, perceived as a random logout while
+  actively working.
+
+## 1.3.4
+
+### Patch Changes
+
+- Fix "Run Shell" not switching the terminal to the newly created shell session. Clicking Run Shell created the shell tab but left the previous session's terminal on screen, so you had to manually click the new tab to actually enter it. Root cause: `runShell()` pre-set `activeSessionId` to the new session's id right before calling `selectSession()`, and `selectSession()` early-returns when the requested id already matches the active one, so it skipped the terminal buffer load, tab activation, and focus. Removed the premature assignment in both the local and remote-SSH shell branches so `selectSession()` runs to completion (matching `runClaude`/`runCodex`/`runGemini`/`runOpenCode`, which already avoid this). Verified end-to-end in a real browser with a negative/positive control.
+
+## 1.3.3
+
+### Patch Changes
+
+- Fix terminal scroll-back in Claude sessions, especially on macOS trackpads (#154).
+  - **Deterministic CLI version detection.** `cliVersion` was often `undefined` because it was scraped from the `Claude Code vX.Y.Z` startup banner, which newer Claude Code builds (2.1.187+) don't reliably print and resumed sessions never show. With the version unknown, wheel-forwarding to Claude's transcript was silently disabled — and since repaint-mode Claude keeps no local terminal scrollback, scrolling up reached nothing. A new `getClaudeCliVersion()` probe (`claude --version`, cached, local-only) seeds the version at session start so forwarding engages. Restored sessions pick it up on restart.
+  - **Trackpad Shift+scroll.** The wheel handler now reads the dominant axis, so a macOS trackpad's Shift+two-finger scroll — which the browser reports as horizontal `deltaX` — reaches xterm's local scrollback instead of collapsing to a fixed one line per tick.
+  - **Opt-out setting.** New per-device App Settings → Input → "Wheel Scrolls Local History" (default off) pins the plain wheel to local scrollback (the pre-#144 behavior) for shell and other non-repaint sessions.
+  - **No more "queued bytes" flicker on scroll.** Wheel-scroll reports now use a fire-and-forget send path (seq-less input frame) instead of the durable exactly-once input queue, so they no longer appear in the pending-bytes connection indicator or churn localStorage. Keystrokes, taps, and clicks still use the durable queue.
+
+## 1.3.2
+
+### Patch Changes
+
+- Make the Cron Jobs modal fully skin-aware and consistent with App Settings' design language.
+  - **Fix white dropdowns:** `.form-select` had no `appearance` reset and the app set no `color-scheme`, so native `<select>` fields rendered as white OS widgets that ignored the active skin. Selects now use `appearance: none` with an opaque `var(--bg-input)` fill, a `var(--border)` outline, and a custom chevron, so they follow the skin (daylight `#202833`, OG `#1a1a1f`). This is on the shared `.form-select` class, so App Settings, Cron, and every other select match and are fixed together.
+  - Set `color-scheme: dark` on `:root` so native select option popups, date/time pickers, and scrollbars render dark across all three (dark) skins instead of flashing white.
+  - Themed the Cron date/time inputs with `var(--bg-input)` / `var(--border)` instead of hardcoded values.
+  - Fixed the Cron toolbar: "+ New Job" / "Refresh" and the footer Save / Cancel now use the full `btn-toolbar` size (matching the App Settings footer), with a wider gap and a divider under the toolbar for better spacing.
+
+## 1.3.1
+
+### Patch Changes
+
+- Redesign the Cron Jobs modal to match the App Settings styling, and fix a bug that left its create form fully expanded.
+  - **Fix:** the cron modal's "New Cron Job" form and all of its conditional rows (Launch Command, Prompt File Path, and the once/interval/daily/weekly schedule fields) never actually collapsed — there is no global `.hidden` utility in the stylesheet and the cron modal never scoped its own, so the form opened fully expanded with every field visible at once. Added a scoped `#cronModal .hidden` rule; the form now stays collapsed until "+ New Job" and only shows the fields relevant to the selected agent type, prompt source, and schedule type.
+  - Sectioned the create/edit form into Basics / Prompt / Schedule / Options with the same section-header dividers used in App Settings, and increased row spacing.
+  - Styled the agent-type / prompt-source / input-mode / schedule-type dropdowns and the datetime-local / time inputs to share the bordered, rounded, focus-ringed field look.
+  - Converted the "Auto-close previous run's session" and "Enabled" toggles into App-Settings-style cards (label + description on the left, compact switch on the right).
+  - Replaced the raw weekday checkboxes with pill toggles that fill with the accent color when selected.
+  - Restyled the job list rows as hover-highlighted cards with pill badges (agent type, schedule, disabled) and right-aligned actions, and gave the modal a divider-topped Cancel / Save footer.
+
+## 1.3.0
+
+### Minor Changes
+
+- Community release: 16 contributor PRs reviewed (multi-agent adversarial review), fixed, and merged. Thanks to @aakhter, @TeigenZhang, @chatgptkrylor, @kvncrw, and @pirronewantlux529-coder!
+
+  **New features**
+  - **Cron jobs** (#141, @chatgptkrylor): recurring scheduled jobs (once/interval/daily/weekly) that spawn a session and send a prompt when due — CRUD + run history (`/api/cron/*`), ⏰ modal UI, per-job concurrency policy and `autoClosePreviousSession` lifecycle, pure unit-tested next-run math. Distinct from the legacy `ScheduledRun`.
+  - **Remote host SSH cases** (#145, @aakhter): link cases on remote hosts (`remote-hosts.json`/`remote-cases.json`), launch sessions over ssh into a durable remote tmux (dedicated `-L codeman-remote` socket; adoption-safe naming), per-host command overrides, injection-guarded schemas, remote tmux probe + ConnectTimeout, remote kill on delete, recovery-safe persistence.
+  - **Command-K session palette + searchable case picker + shortcut registry** (#146, @aakhter): Ctrl/Cmd/Alt+K fuzzy session palette with "Browse all sessions" Session Manager; searchable quick-start case picker (remote-aware labels); rebindable shortcut registry with App Settings → Shortcuts tab and Ctrl+? overlay.
+  - **Unified session list** (#139, @aakhter): `GET /api/sessions/unified` merges live/persisted/lifecycle/transcript sessions into one deduped list (resumed sessions fold via claudeSessionId alias map).
+  - **Unified Session Manager UX** (#153, @aakhter): unified welcome list with mode/LIVE badges + per-row kebab menu, `projectKey` plumbing for "View all in this folder", SSE-driven live list refresh, desktop Session Manager header button.
+  - **Full-scrollback replay** (#148, @aakhter): page reload replays the entire tmux scrollback (`?full=1`, bounded capture with proper maxBuffer) with CRLF normalization for shell panes.
+  - **WebSocket resilience** (#149, @aakhter): reconnect with preserved exponential backoff, per-tab connection identity (multi-tab safe), ACK re-drive, and a truthful connection chip (WS/HTTP/reconnecting states).
+  - **PTY-exit circuit breaker + TMUX scrub** (#147, @aakhter): rapid PTY crash-loops trip a breaker (SSE + critical push notification; explicit-restart-only reset); inherited TMUX vars are scrubbed so Codeman-in-tmux doesn't nest.
+  - **Codex generated-artifact attachments** (#150, @aakhter): codex sessions surface `Saved to: file://…` outputs as attachment cards (realpath-anchored trust, codex-mode-gated, jpg/gif/webp thumbnails).
+  - **Codex response viewer** (#152, @pirronewantlux529-coder): the eye button now works for Codex sessions via 4-layer rollout resolution (history pin → originator → resume-UUID → cwd) with dedup + injected-context filtering.
+  - **HEIC paste conversion** (#151, @aakhter): iPhone HEIC pastes convert to JPEG server-side in a worker thread (concurrency-capped, 64MP decompression-bomb guard, magic-byte detection for mislabeled Android HEIFs). Deps: heic-decode + jpeg-js.
+  - **WebGL renderer toggle** (#140, @kvncrw): per-device setting to switch xterm between WebGL and DOM renderers, cooperating with the GPU-stall auto-fallback marker.
+  - **Raised terminal history defaults** (#138, @aakhter): tmux history-limit 50k→100k lines, PTY buffer 2MB/1.5MB→32MB/24MB (env-clamped so trim always stays below max).
+
+  **Mobile & input fixes**
+  - CJK input loss fixes: IME state machine, focus routing, Android InputConnection recovery — with content-free diagnostics (#143, @TeigenZhang).
+  - Tap/click/wheel restored when the server strips mouse DECSETs — version-gated wheel passthrough (claude ≥ 2.1.187), link-click double-fire fix, Shift+wheel documented (#144, @TeigenZhang).
+  - Response-viewer readability on phones + iOS dvh viewport fix (#142, @TeigenZhang).
+
+  **Docs**: CLAUDE.md accuracy audit (18 verified fixes: security hook-bypass description, env-prefix allowlist, state-file inventory, watcher/function names, counts) + documentation for all new subsystems. README gains a user walkthrough (#141).
+
+  All PRs went through adversarial multi-agent review; ~60 verified findings (including 12 blockers) were fixed on the contributors' branches before merge. Full test suite green: 3,400+ tests.
+
+### Patch Changes
+
+- bf36eb0: Add a **WebGL Renderer** toggle to Settings → Appearance (desktop). WebGL stays on by default; turning it off forces the DOM renderer for users who hit GPU glitches, without needing the `?nowebgl` URL param. Turning it back on (or `?webgl=force`) clears any stale auto-fallback marker. The existing mobile skip and long-task auto-fallback safety net are unchanged. The skip decision is factored into a pure, unit-tested `shouldSkipWebGL()` helper.
+
+## 1.2.2
+
+### Patch Changes
+
+- Centralize terminal history/scrollback/buffer retention limits into config (PR #137, COD-80).
+
+  New `src/config/terminal-history.ts` is now the single source of truth for the terminal scrollback lines, tmux `history-limit`, and server PTY buffer byte caps that were previously scattered as hardcoded literals across `buffer-limits.ts`, `tmux-manager.ts`, and `session.ts`. Each value is overridable (env var or the settings object) and bounds-clamped via a pure `resolveTerminalHistoryConfig()`.
+
+  This change is behavior-neutral: the defaults intentionally match the prior hardcoded values (tmux history-limit 50,000; terminal scrollback 50,000; PTY buffer max 2 MB; trim 1.5 MB) and the existing `CODEMAN_MAX_TERMINAL_BUFFER` / `CODEMAN_TRIM_TERMINAL_TO` env overrides are preserved, so runtime behavior is unchanged on its own. It is the mechanism half of a stacked change; a follow-up raises the defaults.
+  - `buffer-limits.ts` sources `MAX_TERMINAL_BUFFER_SIZE` / `TRIM_TERMINAL_TO` from the resolver.
+  - `tmux-manager.ts` uses `DEFAULT_TMUX_HISTORY_LIMIT` in place of the hardcoded `history-limit 50000`, gains `setHistoryLimit()` (mux-interface + impl) so a settings change applies to live sessions, and re-applies the limit on `respawnPane` so it survives a respawn.
+  - `session.ts` threads a per-session `tmuxHistoryLimit` into the tmux spawn calls; `server.ts` exposes `getTerminalHistoryConfig()` on the route ctx and `system-routes.ts` applies a changed `tmuxHistoryLimit` to live sessions immediately.
+  - `schemas.ts` adds four optional, bounds-clamped settings keys (`terminalScrollbackLines`, `tmuxHistoryLimit`, `terminalBufferMaxBytes`, `terminalBufferTrimBytes`) with a `trim <= max` cross-field check.
+  - New tests: `test/terminal-history.test.ts` (resolver defaults / clamping / trim<=max / non-number fallback) and `test/terminal-history-schema.test.ts` (settings-schema validation).
+
+## 1.2.1
+
+### Patch Changes
+
+- Fix local echo on iOS Safari when switching into a tab whose session already has output. The on-screen-keyboard "heal" (refit + scroll-to-bottom + overlay re-render + one-shot resize) only ran on a keyboard visibility transition, so switching into a tab while the keyboard was already up never triggered it — leaving the local-echo overlay rendering against stale, off-bottom terminal state. Typed characters were invisible (or mispositioned at the cursor row, far below the actual `❯` prompt) until the user manually hid and re-showed the keyboard. `selectSession` now replicates that heal when the keyboard is already visible, so local echo paints correctly on the first keystroke after a keyboard-up tab switch.
+
+## 1.2.0
+
+### Minor Changes
+
+- Merge four feature PRs and harden them for release.
+
+  **Gemini run mode (PR #134, COD-36)** — a third external-CLI backend alongside Codex and OpenCode (`SessionMode` adds `'gemini'`). New `gemini-cli-resolver.ts`, `buildGeminiCommand()` (`--skip-trust`, `--approval-mode {default|auto_edit|yolo|plan}` defaulting to `yolo`, `--model`, `--resume`), `setGeminiEnvVars()` (socket-scoped `tmux setenv` of `GEMINI_*`/`GOOGLE_*` auth incl. Vertex AI), `GET /api/gemini/status` with an install hint (`npm install -g @google/gemini-cli`), run-mode dropdown + welcome "Run Gemini" button + "Run GM" label, `GeminiConfigSchema`, and `GEMINI_*`/`GOOGLE_*` added to the env-override allowlist. Requires tmux (no PTY fallback), like Codex.
+
+  **Cross-session search (PR #133, COD-113)** — `GET /api/search?q=&types=&limit=` federates an in-memory search across session metadata, run-summary events, and attachment-history file entries (substring match, hard caps, no FS reads); history-panel search box in the frontend.
+
+  **Away digest (PR #136, COD-41)** — `GET /api/away-digest` aggregates "what happened while you were away" (lifecycle log, run summaries, live sessions, daily token stats, recent subagents) into categorized sections behind a header-button modal (hidden on phones).
+
+  **Ralph todo-config (PR #135, COD-79)** — per-session `maxTodos` and `todoExpirationMinutes` via `POST /api/sessions/:id/ralph-config`; now persisted in `RalphTrackerState` and read back into the Session Options modal (mirrors `maxIterations` round-trip).
+
+  **Review fixes applied on merge:**
+  - Gemini: fixed two `{success,data}` envelope bugs in `runGemini()` (status check and new-session selection) that made the Run-Gemini button non-functional; fixed `setGeminiEnvVars()` to use the socket-scoped tmux command so Google-auth env injection actually reaches the session.
+  - Gemini parity: tab-mode badge, kill-dialog label, `codeman doctor` registry entry, `isGeminiAvailable` barrel export, `COLORTERM=truecolor`, and alt-screen/scrollback stripping (Ink TUI, like Codex/Claude).
+  - Restored four envelope-shape test assertions weakened during the Gemini PR; added a `runGemini()` regression test covering the envelope path.
+  - Ralph todo-config values now persist across restart and read back correctly instead of always reverting to defaults.
+
+## 1.1.17
+
+### Patch Changes
+
+- Fix the connection indicator flashing "Sending 1B…" on every keystroke. The reliable input-delivery layer (1.1.16) marks each keystroke as briefly pending until its ACK arrives a few milliseconds later, which made the indicator flash on every character while typing on a healthy connection. The indicator is now hidden whenever the connection is healthy and only appears for an actual problem (reconnecting/offline), where it still shows the queued byte count so you know buffered input will be sent.
+
+## 1.1.16
+
+### Patch Changes
+
+- Mobile image uploads, reliable input delivery, and gesture window dragging.
+
+  **Mobile image uploads (camera-roll picker / drag-drop / paste).** The "🖼 Image" button now handles real photo batches: up to 20 images per batch uploaded with bounded concurrency and a live "Uploading N/M…" progress toast (with a summary of successes, failures, and whether the 20-cap trimmed the selection). The per-file limit is raised from 10MB to 50MB (`MAX_PASTE_IMAGE_BYTES`, env-overridable via `CODEMAN_MAX_PASTE_IMAGE_BYTES`) so full-resolution phone photos and large screenshots are accepted. Very large images are downscaled to ≤4096px on the longest edge before upload, fixing iOS Safari's ~16.7M-px `<canvas>` limit that previously made huge photos fail to re-encode. Also fixes a latent concurrency bug the batch path exposed where the first parallel uploads to a session raced on creating `.claude-images/` and failed with EEXIST.
+
+  **Reliable, exactly-once input delivery.** A "sent" prompt could be silently lost on a flaky connection (e.g. a train): a half-open WebSocket accepts `ws.send()` without error while discarding the frame, and nothing was queued or resent. Input is now recorded durably (localStorage) with a stable clientId + monotonic per-session sequence before delivery, and only dropped once the server ACKs it — delivered over the WebSocket (acked via `{t:'ia',seq}`) or, when the socket is down, over POST in order. A 2s sweep force-reconnects a half-open socket; pending input survives reconnects and page reloads. The server applies each `(clientId, seq)` at most once (`Session.shouldApplyInput`), so an at-least-once resend can never type the prompt twice. Untagged input (curl/legacy) is unchanged. See `docs/reliable-input-delivery.md`.
+
+  **Gesture beta: drag agent windows.** With the camera hand-tracking overlay, you can now pinch and move the floating subagent and ultracode run/transcript windows. They keep their glowing connector line to the session tab while moving and can travel across a multi-monitor seam.
+
+## 1.1.15
+
+### Patch Changes
+
+- Security: harden all frontend inline `onclick`/`ondblclick` handlers against a stored-XSS double-context bug.
+
+  Many inline handlers interpolated values as `'${escapeHtml(value)}'` — a JavaScript string literal sitting inside an HTML attribute. The browser HTML-decodes the attribute value _before_ parsing the handler source, so `escapeHtml`'s `&#39;` reverts to a literal `'` and a quote-bearing id/name/path/URL breaks out of the JS string into executable code. `escapeHtml` alone is insufficient for this JS-string-within-HTML-attribute context.
+
+  All affected handlers now use `escapeHtml(JSON.stringify(value))`: `JSON.stringify` JS-encodes and quote-wraps the value, then `escapeHtml` handles the HTML-attribute layer, so the value round-trips as a single inert string argument.
+  - ultracode run/agent cards and minimized-tab badges (`ultracode-panel.js`, `ultracode-windows.js`) — PR #132.
+  - Session tabs (click/rename/gear/detach/close), notifications, subagent windows + dropdowns, the agents/tools/log-viewer/image-popup panels, mux-session monitor rows, and case-management buttons (`app.js`, `notification-manager.js`, `subagent-windows.js`, `panels-ui.js`, `session-ui.js`).
+  - Two non-`escapeHtml` variants of the same class: a pre-escaped mux-session id in `panels-ui.js` (`selectSession`/`killMuxSession`) and a fully raw, unescaped `phase.id` in `orchestrator-panel.js` (`orchestratorSkipPhase`/`orchestratorRetryPhase`).
+
+  The most realistic exploitation vector was file paths in the project-insights log-viewer link, since filenames can legally contain a single quote. Purely numeric interpolations and developer-literal handler strings were left unchanged.
+
+## 1.1.14
+
+### Patch Changes
+
+- Ultracode (Workflow-tool) floating windows — agent transcripts in-page, and minimize-to-tab.
+  - **Agent transcripts open in-page, connected, instead of a detached browser popup.** Clicking an agent card (in a run window or the dock panel) now opens the agent's live transcript as its own draggable floating window, tied by a connector line to its parent run window (falling back to the run's session tab if that window has since closed) — the same line idiom the run windows use. Re-clicking a card focuses the existing window; closing it removes the window and its line. (Previously this spawned a separate `window.open` browser popup.)
+  - **The window "−" button now minimizes into the originating session tab**, mirroring the subagent-window idiom. The window genie-animates into its tab and is tracked there; the tab shows an `ULTRA` badge whose hover/click dropdown lists each minimized item (🧬 run windows, 📄 agent transcripts). Click an item to restore its floating window, or dismiss it with ×. A run minimized while still active keeps tracking in the background and its badge auto-clears shortly after the run finishes. Both run windows and agent-transcript windows minimize into the same merged badge.
+  - Removed the old collapse-to-header behavior that the "−" button previously triggered (now superseded by minimize-to-tab).
+
+## 1.1.13
+
+### Patch Changes
+
+- Keep the `/compact` button in the extended (full) mobile keyboard accessory bar; only the simple bar drops it. (1.1.12 had removed it from both.)
+
+## 1.1.12
+
+### Patch Changes
+
+- Remove the `/compact` button from the mobile keyboard accessory bar. It had been reintroduced in 1.1.10; this removes the button from both the simple and full accessory-bar layouts (the underlying command handler is left in place as inert plumbing).
+
+## 1.1.11
+
+### Patch Changes
+
+- Ultracode (Workflow-tool) run visualization — much better live tracking.
+
+  While a run is in flight, the watcher previously showed empty agent slots ("agent N", 0 tokens, raw `wf_…` id as the title) because the detailed completion JSON only lands when the run finishes. The live path now enriches in-flight runs directly from the on-disk transcript tree:
+  - **Real per-agent stats mid-run** — tokens and tool-call counts are parsed from each `agent-<id>.jsonl` transcript (tool counts match the final accounting exactly; token totals land within ~1% of the completion value), with model and a prompt preview. All mtime-cached (transcripts, journal, and script meta) so idle polls do no extra reads.
+  - **Readable window/run title** — workflow name, summary, and phases are derived from the persisted `workflows/scripts/<name>-<runId>.js` instead of showing the raw run id.
+  - **Agent status colors** — done agents show green, working agents show yellow (this also fixes the run/agent status badges, which referenced undefined `--success`/`--warning` CSS variables and were rendering with no color).
+  - **Connector line** — the floating-window → session-tab line now uses the session-tab accent blue (was purple).
+  - **Click a run to open its floating window** — clicking a workflow in the dock panel opens (or focuses) its floating window with the connector line, in addition to the auto-popped windows.
+  - Agents are ordered by journal launch order; concurrent run-detail fetches are de-duplicated.
+
+## 1.1.10
+
+### Patch Changes
+
+- Mobile CJK input, iPad keyboard accessory bar, and terminal touch interaction fixes (PRs #130, #131).
+
+  Mobile / CJK (#130):
+  - Restore reliable real-time CJK (e.g. Pinyin) composition in the always-visible textarea, and refocus input when the terminal is tapped.
+  - Stop clearing the textarea during `compositionstart` — some IMEs include existing text in the composition region, and clearing it mid-composition corrupted input.
+  - iPad-specific fixes: `#cjkInput` positioning, paste-dialog placement, and duplicated voice-dictation output.
+  - Split CJK keyboard positioning by device size (phones vs iPad use different keyboard offsets).
+  - iPad accessory-bar styling/positioning: moved the accessory-bar and paste-overlay base styles out of the `max-width:1023px`-gated mobile stylesheet so iPad landscape (≥1024px) renders them correctly.
+  - Raise the toolbar stacking context while the case-settings popover is open so the popover is no longer hidden behind the toolbar.
+  - Restore the `/compact` button to the keyboard accessory bar (with double-tap confirmation, like `/clear`); the paste dialog now submits pasted text on "Send".
+
+  Terminal touch + forced redraw (#131):
+  - Enable terminal touch interaction on all touch devices and show the stop button on touch devices.
+  - Add an 8px tap threshold so micro-drift is treated as a tap, not a scroll, fixing cases where a tap failed to register.
+  - Tap-to-position the cursor via a synthesized mouse report, gated on the live mouse-tracking mode so it never triggers local text selection when tracking is off; let SGR mouse reports through to the PTY even while the CJK input field owns focus.
+  - Suppress the cursor/momentum side effects of a sub-threshold tap so a jittery tap no longer both positions the cursor and starts a momentum fling.
+  - New opt-in, per-device "Redraw Terminal" header button (`showRedrawButton`, default off) that forces an xterm redraw via a resize jitter to clear occasional rendering glitches; the resize path now accepts a `force` flag (threaded through the session, HTTP, and WebSocket resize routes) that guarantees a SIGWINCH/redraw at the current device's size without bypassing multi-client resize arbitration.
+
+## 1.1.9
+
+### Patch Changes
+
+- Two welcome-screen tunnel changes:
+  - **UI (Daylight Blue skin):** the **Cloudflare Tunnel** button is now purple (was orange/yellow), keeping the three welcome buttons visually distinct — Claude blue, Tunnel purple, OpenCode green.
+  - **Enable a tunnel without `CODEMAN_PASSWORD`, with a warning.** Previously enabling the Cloudflare tunnel with no password set was hard-refused unless you set `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1`. Now you can opt in straight from the browser: clicking the tunnel toggle without a password pops a **security confirm dialog** ("publishes this machine to a public URL with no login — effectively remote code execution; set CODEMAN_PASSWORD instead"), and only on confirm does it enable, sending an explicit per-request `acknowledgeUnauthTunnel:true`. The server logs a loud warning whenever a passwordless public tunnel starts. curl/API/CLI callers are unchanged — still refused unless they set a password, set the env var, or pass `acknowledgeUnauthTunnel:true` — so nothing gets exposed accidentally. The acknowledgment is an action field and is never persisted to settings.json.
+
+## 1.1.8
+
+### Patch Changes
+
+- UI (Daylight Blue skin): give the welcome-screen action buttons distinct colors instead of all reading blue. **Run Claude Code** keeps the blue accent, **Cloudflare Tunnel** now uses Cloudflare's brand orange, and **Run OpenCode** uses an emerald green — so the three are visually distinguishable at a glance. Scoped to the default `daylight-blue` skin only (daylight-green and OG are unchanged), with matching hover/active states and dark ink for contrast. Verified in a real browser: the three buttons compute to blue / orange / green gradients on the welcome overlay.
+
+## 1.1.7
+
+### Patch Changes
+
+- Fix: terminal scroll-up (scrollback) intermittently breaking for **Claude** sessions — most visible on iPhone, where you suddenly "can't scroll up the Claude console."
+
+  Root cause: Claude Code periodically emits alternate-screen switches (`\x1b[?1049h`/`\x1b[?47h`/`\x1b[?1047h`), scrollback-erase (`\x1b[3J`), and mouse-tracking enables — typically when it draws a full-screen UI (pickers/dialogs, the boot welcome). xterm.js obeys these by moving to the scrollback-less alternate buffer (or wiping saved lines / hijacking the wheel), so the conversation history becomes unreachable until Claude returns to its normal view. Codeman already stripped these sequences so history stays scrollable, but the strip was gated to **Codex mode only** — Claude (and the equivalent buffer-replay path) let them through.
+
+  The strip is now shared via a single `isAltScreenStripMode(mode)` predicate (`codex || claude`) applied at BOTH sites that were Codex-only: the live PTY stream (`Session._handleTerminalOutput`, including the split-across-chunks carry reassembly) and the `/terminal` buffer replay used on tab-switch/reconnect. `shell` is deliberately excluded so full-screen TUIs run from a shell (vim/less/htop) keep their alternate screen; `opencode` is also unchanged.
+
+  Verified end-to-end on an isolated instance against a real Claude session: the replayed buffer and live stream now carry zero alt-screen/scrollback-erase/mouse sequences, the terminal stays in the normal buffer with scrollback intact, and touch swipe-up scrolls correctly. Covered by new unit tests (`test/claude-scrollback-strip.test.ts`); the existing Codex strip tests are unchanged.
+
+## 1.1.6
+
+### Patch Changes
+
+- Fix: ultracode floating run windows now pop on a fresh device/browser that loads while a run is already active.
+
+  `ultracodeFloatingWindows` syncs from the server (it's a non-display setting), but on a first-time device the SSE `getLightState` run snapshot can seed the run list BEFORE the async settings load resolves — so the floating-window gate read `false` at that instant and skipped any already-active run, leaving the window un-popped until the next ~10s watcher tick. The app now re-runs `syncAllUltracodeFloatingWindows()` once server settings finish loading (in the `loadAppSettingsFromServer().then()` callback), so an in-flight run pops its window immediately. Idempotent: open windows are left as-is, and if the setting is off any premature windows are torn down. Verified end-to-end against a real in-flight run on an isolated instance — a pristine browser (empty localStorage) seeds the setting from the server and pops the active run's window ~0.4s after first paint.
+
+  Also corrected a stale `@fileoverview` comment in `ultracode-windows.js` that claimed the floating windows are gated on `showUltracodeAgents`; they are gated on the dedicated `ultracodeFloatingWindows` toggle (only the docked "Ultracode Agents" panel uses `showUltracodeAgents`).
+
+## 1.1.5
+
+### Patch Changes
+
+- Fix: the Ultracode Agents panel's (×) Close button now fully hides the panel.
+
+  `closeUltracodeAgentsPanel()` only removed the `open` class, which drops the bottom-docked drawer to its collapsed _peek_ state (the 36px header strip stays visible) rather than closing it — so clicking (×) looked like it did nothing. It now also adds the `hidden` class (`display:none`), mirroring `closeSubagentsPanel()`. It deliberately does NOT flip the `showUltracodeAgents` setting (that also gates the run watcher and floating windows); the header launcher button reopens the panel. Verified in a real browser: after (×) the panel computes `display:none`.
+
+## 1.1.4
+
+### Patch Changes
+
+- Fix: ultracode floating run windows (and the live dock panel) now appear DURING an in-flight Workflow/ultracode run, not only after it finishes.
+
+  The Workflow runtime writes the run-state file `…/workflows/wf_<id>.json` only at completion (always a terminal status); while a run is live, its only on-disk state is the sibling `…/subagents/workflows/wf_<id>/` transcript tree. `workflow-run-watcher` previously scanned only the completion file, so it never observed a run until it was already terminal — and the floating-window auto-pop is gated on an ACTIVE run, so it never fired for a live run (the feature was effectively dead for in-flight runs).
+
+  The watcher now ALSO scans the `subagents/workflows/wf_<id>/` transcript tree and synthesizes a minimal ACTIVE run (status `running`, agent slots keyed by their `agentId` so the agent-card → live-transcript click still works, `lastActivityAt` from the newest agent/journal mtime, per-agent done/running derived from the run journal's `result` events) when no completion file exists yet. When the run finishes, the real `wf_<id>.json` supersedes the synthesized record (same runId), restoring full phase/token detail and the normal finish → 8s-grace auto-close flow. The watcher stays standalone (it never imports subagent-watcher). Verified end-to-end against a real in-flight run; adds unit coverage for live synthesis, agentId preservation, journal-derived state, empty-dir skipping, and completion-file precedence.
+
+## 1.1.3
+
+### Patch Changes
+
+- Ultracode floating run windows + a dedicated toggle to control them.
+  - **New: floating ultracode run windows.** When enabled, each active ultracode / Workflow run pops a small draggable window (like the file browser) connected by a glowing line to its originating session tab — the same connector-line idiom as subagent windows. The tab is resolved by matching the run's `sessionUuid` to a session's `claudeSessionId`. The window mirrors the live agent grid (phases, per-agent model / tokens burned / tool calls / state), auto-closes a few seconds after its run finishes, and remembers windows you explicitly dismiss so they don't re-pop. These windows are **additional to** the existing docked "Ultracode Agents" master-detail panel, which is unchanged.
+  - **New setting "Ultracode Floating Windows"** (App Settings → Display), **default OFF**, independent of the "Ultracode Agents" panel toggle. Either toggle now starts the server-side workflow-run watcher (at boot and on live settings change), so the floating windows work even with the docked panel off.
+  - Internals: new frontend module `ultracode-windows.js` (load order 15.5); ultracode connector lines are appended into the shared `#connectionLines` SVG within the existing batched read/write reflow pass in `subagent-windows.js`; new `ultracodeFloatingWindows` app-settings key in `schemas.ts`; watcher gating in `server.ts` + `system-routes.ts` now ORs both ultracode toggles.
+  - Docs: `CLAUDE.md` brought up to date for the 1.1.2 ultracode/workflow-run subsystem (Agents / Frontend / Types / Config inventories, JS load order, a Key Patterns entry) and the new floating-windows feature.
+
+## 1.1.2
+
+### Patch Changes
+
+- Ultracode/Workflow run visualization + subagent discovery fixes.
+  - **Ultracode / Workflow run visualization** (new, opt-in): App Settings → Display → "Ultracode Agents" (`showUltracodeAgents`, default OFF) adds a master-detail tab that shows ultracode / Workflow-tool runs like Claude Code's "working agents" view — the LEFT pane lists runs and their phases (selectable tasks), the RIGHT pane shows each run's agents with model, live state, tokens burned, and tool calls. Clicking an agent opens its live transcript. Backed by a new standalone workflow-run watcher that reads the per-run state JSON (stripping the heavy embedded script/result/logs so payloads stay small), exposes `GET /api/workflows` and `GET /api/workflows/:runId`, and broadcasts `workflow:run_discovered/updated/removed` SSE events. The header launcher and panel stay hidden until the setting is enabled (the setting is synced across devices, not per-device).
+  - **Subagent tracking discovery fix**: restored subagent tracking after Claude Code changed the on-disk format from `agent-*.jsonl` to `agent-*.meta.json` (background agents were showing 0). Also discovers workflow-nested subagents under `subagents/workflows/<wf>/` and hardens the meta→transcript upgrade path so an agent re-points to its `.jsonl` transcript once it appears.
+  - **File viewer**: opens audio, SVG, and other binary files the same way the attachments viewer does.
+  - **Tooling**: hardened the real-overview screenshot capture script and documented the `deviceScaleFactor` / static-cache gotchas.

 Codeman requires tmux, so Windows users need [WSL](https://learn.microsoft.com/en-us/windows/wsl/install). If you don't have WSL yet: run `wsl --install` in an admin PowerShell, reboot, open Ubuntu, then install your preferred AI coding CLI inside WSL ([Claude Code](https://docs.anthropic.com/en/docs/claude-code), [OpenCode](https://opencode.ai), or [Codex](https://developers.openai.com/codex/cli)). After installing, `http://localhost:3000` is accessible from your Windows browser.

+## Using Codeman — A Human's Guide
+
+A start-to-finish walkthrough for driving Codeman from the browser. If you just installed, this is where to begin.
+
+### 1. Launch the server
+
+```bash
+codeman web                       # localhost:3000 (loopback only — safe default)
+codeman web --port 8080           # custom port (or set CODEMAN_PORT)
+codeman web --https               # self-signed TLS (only needed for remote access)
+codeman web -H 0.0.0.0            # bind LAN — REQUIRES CODEMAN_PASSWORD (see Security)
+```
+
+Open the printed URL. The page is a single dashboard; everything below happens there.
+
+### 2. Create your first session
+
+Click **+ New Session** (or **Quick Start**). A session is one AI CLI running in its own tmux-backed terminal. You choose:
+
+| Field                        | What it does                                                                                                        |
+| ---------------------------- | ------------------------------------------------------------------------------------------------------------------- |
+| **Working directory / case** | The folder the agent operates in. A "case" is just a named working dir Codeman remembers.                           |
+| **CLI / run mode**           | `Claude` (default), `OpenCode`, `Codex`, `Gemini`, or `Terminal` (plain shell).                                     |
+| **Model**                    | Per-session model (App Settings → Claude Model). A soft default — `/model` still works in-session.                  |
+| **Effort / Ultracode**       | Reasoning effort (`low`–`max`) or `ultracode` for dynamic multi-agent workflows. Switchable anytime with `/effort`. |
+
+Hit start — Codeman spawns the CLI via a real PTY and streams it to your browser over SSE.
+
+### 3. Read the dashboard
+
+- **Tabs (top)** — one per session. `Alt+1`-`9` to jump, `Ctrl+Tab` for next, drag to reorder.
+- **Terminal (center)** — a real `xterm.js` terminal; full TUIs render correctly. Type directly and press **Enter** to send. `Shift+Enter` inserts a newline.
+- **Side panels** — Respawn, Ralph, Orchestrator, Cron, Subagents, Settings (toggled from the toolbar).
+
+### 4. Talk to the agent
+
+- **Type prompts** straight into the terminal — input is delivered exactly-once even across reconnects (a dropped link never loses or double-sends a prompt).
+- **Paste or drag-and-drop images** directly into the session.
+- **Voice input** — `Ctrl+Shift+V` (Deepgram Nova-3, with auto-silence stop).
+- **Attachments** — register external files/docs and preview Office/PDF inline.

+| **Ralph / Todo** | A self-driving loop that tracks a todo list and keeps working until done.                                                         | Ralph tab          |
+| **Orchestrator** | Turn one goal into a phased plan and drive it to completion across agents.                                                        | Orchestrator panel |
+| **Cron**         | Saved, named jobs on a schedule (`once`/`interval`/`daily`/`weekly`) that spawn a session and send a prompt when due.             | ⏰ Cron button     |
+| **Auto-resume**  | Automatically continue after a subscription rate-limit resets.                                                                    | Respawn tab (top)  |
+
+### 6. Reach it from anywhere
+
+- **Phone/tablet** — the UI is fully touch-optimized; scan the desktop **QR code** to log in without typing a password.
+- **Outside your network** — `./scripts/tunnel.sh start` opens a Cloudflare tunnel (set `CODEMAN_PASSWORD` first).
+- **SSH** — the `sc` chooser attaches to any session from a terminal (`sc` interactive, `sc 2` quick-attach, `sc -l` list).
+
+### 7. Operate & maintain
+
+- **App Settings** — model, effort, theme/skin, notifications, display toggles, per-CLI options.
+- **Self-update** — git-clone installs update in place from **Settings → Updates**.
+- **Deploy your own changes** — see [Development](#development).
+
+> ⚠️ **Safety:** if you're working _inside_ a Codeman-managed session (`echo $CODEMAN_MUX` → `1`), never run `tmux kill-session` / `pkill claude` directly — use the web UI or `./scripts/tmux-manager.sh`.

 ### Network & access
 
-- **Loopback by default** — binds `127.0.0.1`, reachable only from the same machine, so the no-password default is safe out of the box. 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

 ### Always-on browser hardening (v0.9.5)
 
 These run for **every** request — before auth, even on the default no-password loopback install:
 
 - **Host-header allowlist → blocks DNS rebinding.** A custom domain rebound to `127.0.0.1` is rejected with `403 host not allowed` before any handler runs. Allowed: `localhost`, any IP literal, the bind host, `.ts.net` / `.trycloudflare.com` / `.cfargotunnel.com`, the active managed tunnel, and `CODEMAN_ALLOWED_HOSTS` (add custom reverse-proxy domains here — comma-separated; exact host or leading-dot `.suffix` for subdomains)
-- **Cross-site Origin / CSRF guard.** On state-changing methods (`POST`/`PUT`/`PATCH`/`DELETE`) the `Origin` must pass the same allowlist, else `403 cross-site request blocked`. A *missing* Origin is allowed (so `curl`, the CLI, and Claude Code hooks keep working); only a present-but-foreign or opaque `null` origin is rejected

A _missing_ Origin is allowed (so `curl`, the CLI, and Claude Code hooks keep working); only a present-but-foreign or opaque `null` origin is rejected
 - **Raw `text/plain` bodies.** The global parser no longer JSON-parses `text/plain`, closing the CORS "simple request" CSRF vector where a cross-site `fetch` could smuggle JSON into a write route with no preflight
 - **WebSocket origin validation.** The terminal WS upgrade runs the same Host + Origin check and closes with code `4003` on failure (anti-CSWSH)
 - **XSS-escaped agent output.** AI-derived strings (tool names, command arguments, subagent descriptions) are HTML-escaped at every injection site before rendering in the subagent / activity panels

+## Driving Codeman from an Agent — Programmatic Guide
+
+For AI agents and automation that control Codeman without a browser: an agent that spins up worker sessions, a CI bot, or **Claude Code running _inside_ a Codeman session orchestrating other sessions**. Everything the UI does is HTTP + a CLI, so an agent can do it too.
+
+### Detect that you're inside Codeman
+
+When a CLI runs in a Codeman-managed session, these environment variables are set — read them instead of hardcoding anything:
+
+| Variable                   | Meaning                                                                                                                              |
+| -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
+| `CODEMAN_MUX=1`            | You're in a managed tmux session. **Never** `tmux kill-session` / `pkill claude` / `pkill tmux` — you'll kill yourself or a sibling. |
+| `CODEMAN_API_URL`          | Base URL of the API (e.g. `https://127.0.0.1:3000`). Use it for every call below.                                                    |
+| `CODEMAN_SESSION_ID`       | _Your own_ session id. Use it to avoid acting on yourself.                                                                           |
+| `CODEMAN_HOOK_SECRET_FILE` | Path to the hook secret (required on `/api/hook-event` while a managed tunnel is up).                                                |
+
+### Rules of the road (read before you POST)
+
+1. **Single-line input only.** Programmatic input is sent as literal text **+ Enter** in one shot. Multi-line strings break the agent TUI (Ink) — send one line, or split into multiple calls.
+2. **Make input idempotent.** Include a stable `clientId` and a monotonic per-session `seq` on `POST …/input`. The server de-duplicates, so a retry after a dropped connection can't double-deliver a prompt.
+3. **Auth.** If `CODEMAN_PASSWORD` is set, send HTTP Basic auth (user `admin` or `CODEMAN_USERNAME`) or a `codeman_session` cookie. The default loopback install is passwordless. A missing `Origin` header is allowed, so plain `curl` works; cross-site browser origins are rejected (CSRF guard).
+4. **Response envelope.** Most endpoints return `{ "success": true, "data": … }` (errors: `{ "success": false, "error", "errorCode" }`). A few legacy GETs return bare bodies — **handle both** (`body.data ?? body`).
+5. **`/api/v1/*`** is a stable alias of `/api/*`.
+
+### Recipes
+
+```bash
+API="${CODEMAN_API_URL:-http://127.0.0.1:3000}"
+# (add  -u admin:"$CODEMAN_PASSWORD"  to each call if a password is set)
+
+# 1. See what's running
+curl -s "$API/api/sessions" | jq '.data // .'
+
+# 2. Spin up a worker session (a "case" = named working dir)
+curl -s -X POST "$API/api/quick-start" \
+  -H 'Content-Type: application/json' \
+  -d '{"caseName":"refactor-auth","mode":"claude","effort":"high"}' | jq
+
+# 3. Send a prompt into a session (exactly-once: clientId + seq)
+curl -s -X POST "$API/api/sessions/$SID/input" \
+  -H 'Content-Type: application/json' \
+  -d '{"input":"Run the test suite and summarize failures","useMux":true,"clientId":"agent-1","seq":1}'
+
+# 4. Read the terminal back
+curl -s "$API/api/sessions/$SID/output" | jq -r '.data // .'
+
+# 5. Stream live events (session output, agent activity, status)
+curl -sN "$API/api/events"          # Server-Sent Events
+
+# 6. Schedule recurring work (cron-style job)
+curl -s -X POST "$API/api/cron/jobs" \
+  -H 'Content-Type: application/json' \
+  -d '{"name":"nightly-deps","agentType":"claude","workingDir":"/home/me/proj",
+       "promptMode":"inline_text","promptText":"Update dependencies and open a PR",
+       "inputMode":"typed","scheduleType":"daily","dailyTime":"03:00",
+       "enabled":true,"concurrencyPolicy":"warn_only"}' | jq
+
+# 7. Inspect background sub-agents and their transcripts
+curl -s "$API/api/subagents" | jq '.data // .'
+curl -s "$API/api/subagents/$AID/transcript" | jq -r '.data // .'
+
+# 8. Whole-system snapshot (sessions, settings, respawn, stats)
+curl -s "$API/api/status" | jq
+```
+
+### Or use the bundled CLI
+
+The same operations are available as commands (`codeman <cmd>`, aliases in parentheses) — handy from a shell tool inside a session:
+
+```bash
+codeman session start -d /path/to/repo   # (s)  start a session
+codeman session list                     #      list sessions
+codeman session logs <id>                #      tail output
+codeman task add "fix the failing test"  # (t)  queue a task
+codeman ralph start --min-hours 8        # (r)  launch the autonomous loop
+codeman attach <path>                     #      attach a Claude hook context
+```
+
+### Hooks (events flowing _back_ to Codeman)
+
+Codeman registers Claude Code hooks that `POST /api/hook-event` (`permission_prompt`, `idle_prompt`, `stop`, `task_completed`, …) so the dashboard reacts in real time. This endpoint is auth-exempt on loopback but, under a managed tunnel, requires the `X-Codeman-Hook-Secret` header (read it from `$CODEMAN_HOOK_SECRET_FILE`). You normally don't call this by hand — Codeman wires it up — but it's how the autonomy layers "see" what the agent is doing.

+# SPEEDRUN.md — Fast-execution protocol for Claude
+
+Read this when the goal is **throughput**: get correct, verified work done with
+minimum ceremony. This does **not** relax correctness or the safety rules in
+`CLAUDE.md` — those still win. It removes _waste_, not _rigor_.
+
+> Precedence: `CLAUDE.md` > explicit user instructions > this file. If anything
+> here conflicts with `CLAUDE.md`, `CLAUDE.md` wins.
+
+---
+
+## The mindset
+
+- **Act, don't announce.** No "I'm going to now…" preamble. Do the thing, report
+  the result.
+- **Cheapest proof that the change works.** Pick the smallest check that actually
+  demonstrates correctness — not the biggest.
+- **Batch aggressively.** Independent reads, greps, and edits go in **one**
+  message with parallel tool calls. Never serialize work that has no dependency.
+- **Momentum over perfection.** Land a correct increment, verify it, move on.
+  Don't gold-plate untouched code.
+
+---
+
+## Loop (repeat until done)
+
+1. **Orient once** — one parallel burst of reads/greps to load the context you
+   need. Don't re-read files the harness says are already current.
+2. **Change** — make the edit(s). Batch independent edits.
+3. **Verify cheaply** — the smallest check that proves _this_ change (see below).
+4. **Advance** — next item. Only re-verify what you touched.
+5. **Stop** at: list empty, a hard blocker, or a decision that's genuinely the
+   user's to make.
+
+---
+
+## Verification ladder — climb only as high as the change needs
+
+| Change kind | Cheapest sufficient check |
+|-------------|---------------------------|
+| Types / signatures / imports | `tsc --noEmit` (or `--watch` already running) |
+| One module's logic | `npm test -- test/<file>.test.ts` (the **one** relevant file) |
+| A named behavior | `npm test -- -t "pattern"` |
+| Route/handler | `app.inject()` route test, or one `curl` against the running dev server |
+| Frontend render | Playwright load + assert (`waitUntil: 'domcontentloaded'`, wait 3–4s) |
+| Broad / pre-merge | `npm run test:ci` (the CI-equivalent sweep) |
+
+**Hard rules (never skip, even in a rush):**
+- ⚠️ **Never run bare `npm test`** — it pulls in browser/visual suites that hang
+  or fail locally. Always pass a file or `-t`, or use `test:ci`.
+- ⚠️ **Never COM without verifying the change actually works** first (curl the
+  endpoint / Playwright the UI). "Compiles" ≠ "works".
+- ⚠️ **Session safety** — check `$CODEMAN_MUX`; never `tmux kill-session` /
+  `pkill claude` in a managed session.
+- ⚠️ **Single-line prompts** for any programmatic session input.
+
+---
+
+## Speed tactics that pay off here
+
+- **Parallel exploration**: dispatch `Explore` subagents (or one parallel grep
+  burst) instead of serial file-by-file reading when scope is uncertain.
+- **`tsc --noEmit --watch`** in the background — instant type feedback, no repeat
+  cold starts.
+- **Target one test file** — `fileParallelism: false` means the suite is serial;
+  running one file is dramatically faster than the sweep.
+- **`curl localhost:3000/api/...`** beats spinning up a browser for backend
+  checks. Reserve Playwright for actual UI rendering.
+- **Trust the harness** — if it says a file you just edited is current, don't
+  re-Read it to "confirm". The Edit already succeeded or it would have errored.
+
+---
+
+## Anti-patterns (these masquerade as speed, but cost time)
+
+- Running the full test suite to check a one-file change.
+- Re-reading files you already have in context.
+- Narrating a plan you're about to execute anyway.
+- Serial tool calls that have no dependency between them.
+- Claiming "done / fixed / passing" **before** running the check that proves it.
+- Deploying (COM) on green typecheck alone, without exercising the real flow.
+
+---
+
+## Stop-conditions (don't rush past these)
+
+Stop and surface, don't guess, when you hit:
+- A **destructive / hard-to-reverse** action (delete, overwrite, force-push).
+- An **outward-facing** action (publishing, sending, deploying) not already
+  authorized.
+- A **genuine product decision** the code can't answer.
+- A **failing verification you can't explain** — debug it (see
+  `superpowers:systematic-debugging`), don't paper over it.
+
+---
+
+## Definition of done
+
+A task is done when **all** hold:
+- The change is made.
+- The cheapest sufficient check **ran** and **passed** — evidence, not assertion.
+- No new type errors / lint errors introduced (`tsc --noEmit`, `npm run lint`).
+- You state plainly what was done and what proved it. If a step was skipped or a
+  test failed, say so — don't hedge, don't overclaim.

+# Claude Code Build Brief: Add Scheduling to Codeman
+
+## 0. Purpose of This Brief
+
+You are Claude Code working inside the Codeman repository.
+
+Your task is to add a **small, reliable scheduling layer** to Codeman while preserving Codeman's existing architecture and session-management behavior.
+
+This is not a greenfield rewrite. This is not a full product rebuild. This is a focused extension.
+
+The target user wants Codeman-like tmux/web/session management, but with first-class scheduled jobs for Claude, Codex, OpenCode, Terminal, or any other configurable coding-agent harness.
+
+---
+
+## 1. Non-Negotiable Goal
+
+Add scheduling to Codeman so a user can define a scheduled coding-agent job that:
+
+1. Has a name.
+2. Uses an existing Codeman-supported agent/session type where possible.
+3. Has a working directory.
+4. Has a prompt or prompt file.
+5. Has a schedule.
+6. Can be enabled or disabled.
+7. Can be manually run now.
+8. When due, creates a Codeman/tmux session.
+9. Sends the configured prompt into that session.
+10. Records last run, next run, status, and run history.
+
+The first working version should prioritize **scheduling correctness and reuse of Codeman's existing tmux/session system** over UI polish.
+
+---
+
+## 2. Core Architectural Rule
+
+Do **not** rebuild Codeman's session layer.
+
+Reuse existing Codeman functionality for:
+
+- Creating sessions.
+- Naming sessions.
+- Launching Claude/Codex/OpenCode/Terminal sessions.
+- Sending input into sessions.
+- Displaying sessions in the web UI.
+- Killing sessions.
+- Tracking session status if already supported.
+
+If an internal API/service/function already exists, reuse it.
+
+If no reusable function exists, create a thin wrapper around the existing implementation rather than duplicating logic.
+
+---
+
+## 3. Product Boundary
+
+This build is **Codeman + Scheduler**.
+
+It is not yet:
+
+- A full quota engine.
+- A full lock manager.
+- A replacement for Codeman's terminal UI.
+- A new FastAPI application.
+- A multi-tenant SaaS platform.
+- A complex cron-management product.
+- A full agent autonomy framework.
+
+Keep the build small and shippable.
+
+---
+
+## 4. Required Working Scope for v0.1
+
+Implement the following minimum features.
+
+### 4.1 Scheduled Jobs List
+
+Create a UI page showing all scheduled jobs.
+
+Each row/card should show:
+
+- Job name.
+- Agent/session type.
+- Working directory.
+- Schedule type.
+- Enabled/disabled state.
+- Last run time.
+- Next run time.
+- Last run status.
+- Actions:
+  - Run Now.
+  - Enable/Disable.
+  - Edit.
+  - Delete.
+
+### 4.2 Create/Edit Scheduled Job
+
+Create a form for scheduled jobs with these fields:
+
+- `name`
+- `agent_type`
+  - Reuse Codeman's existing session/agent types where possible.
+  - Include at least Terminal/custom command if supported.
+- `working_directory`
+- `launch_command` if needed by Codeman's model.
+- `prompt_mode`
+  - `inline_text`
+  - `prompt_file_path`
+- `prompt_text`
+- `prompt_file_path`
+- `input_mode`
+  - `paste`
+  - `typed`
+- `schedule_type`
+  - `once`
+  - `interval_minutes`
+  - `daily_time`
+  - `weekly_time`
+- `run_at` for one-time jobs.
+- `interval_minutes` for interval jobs.
+- `daily_time` for daily jobs.
+- `weekly_days` and `weekly_time` for weekly jobs.
+- `enabled`
+- `notes` optional.
+
+Do not build a complex visual cron editor in v0.1.
+
+### 4.3 Run Now
+
+Every scheduled job must support a `Run Now` action.
+
+Run Now should:
+
+1. Create a new session through Codeman's existing session creation logic.
+2. Send the configured prompt into the session using Codeman's existing input mechanism.
+3. Create a run-history record.
+4. Update last-run fields.
+5. Redirect or link the user to the created Codeman session.
+
+### 4.4 Background Scheduler Loop
+
+Add a small background scheduler loop that runs inside the Codeman backend process.
+
+The loop should:
+
+1. Wake every 15-60 seconds.
+2. Load enabled schedules.
+3. Find schedules where `next_run_at <= now`.
+4. Create a scheduled run.
+5. Launch the session using existing Codeman session logic.
+6. Send the prompt.
+7. Record run history.
+8. Compute the next run time.
+9. Avoid duplicate launches if the loop overlaps or restarts.
+
+Keep this simple and robust.
+
+### 4.5 Run History
+
+Every scheduled execution should create a run-history record.
+
+Track:
+
+- `id`
+- `scheduled_job_id`
+- `session_id` or Codeman session reference.
+- `session_name` if applicable.
+- `started_at`
+- `finished_at` optional.
+- `status`
+  - `created`
+  - `session_started`
+  - `prompt_sent`
+  - `failed`
+- `error_message` optional.
+- `trigger_type`
+  - `scheduled`
+  - `manual_run_now`
+- `created_session_url` or route reference if easy.
+
+---
+
+## 5. Scheduling Rules
+
+### 5.1 Once
+
+Run at a specific date/time.
+
+After successful launch:
+
+- Set `enabled = false`, or mark as completed.
+
+### 5.2 Interval
+
+Run every N minutes.
+
+Example:
+
+- Every 60 minutes.
+- Every 240 minutes.
+
+After launch:
+
+- `next_run_at = now + interval_minutes`.
+
+### 5.3 Daily
+
+Run every day at HH:MM.
+
+After launch:
+
+- Compute the next occurrence of HH:MM after now.
+
+### 5.4 Weekly
+
+Run on selected weekdays at HH:MM.
+
+After launch:
+
+- Compute the next selected weekday/time after now.
+
+### 5.5 Timezone
+
+Use the server's local timezone for v0.1 unless Codeman already has timezone handling.
+
+Add a visible note in the UI:
+
+> Times use the server's local timezone.
+
+Do not overbuild timezone support in v0.1.
+
+---
+
+## 6. Data Storage Decision
+
+First inspect Codeman's existing persistence model.
+
+If Codeman already has a database or persistence layer:
+
+- Reuse it.
+- Add scheduled job and scheduled run models/tables/records using the existing pattern.
+
+If Codeman uses files or JSON state:
+
+- Use the same style for v0.1.
+- Prefer simple persistence over introducing a heavy new dependency.
+
+If there is no appropriate persistence layer:
+
+- Add SQLite only if it fits the codebase cleanly.
+- Otherwise use a JSON file store for the first version.
+
+Do not introduce Postgres, Redis, Celery, or a separate scheduler service.
+
+---
+
+## 7. Concurrency and Duplicate-Run Guard
+
+Implement a basic duplicate-run guard.
+
+A schedule should not launch twice for the same due time.
+
+Minimum acceptable approach:
+
+- Before launching, create/update a run record with a `created` or `launching` state.
+- Use a schedule-level `last_triggered_at` or `last_due_key` to avoid double launching.
+- If launch fails, record failure clearly.
+
+Do not build distributed locks. Codeman is expected to be local/single-instance for v0.1.
+
+---
+
+## 8. Multi-Session Warning
+
+When the user clicks `Run Now`, show a warning if there are already active sessions for the same agent type.
+
+Minimum behavior:
+
+- If active sessions exist, show a confirmation warning.
+- User can continue anyway.
+
+For scheduled automatic runs:
+
+- Add a setting on the scheduled job:
+  - `warn_only`
+  - `skip_if_same_agent_running`
+
+Default:
+
+- `warn_only` for manual runs.
+- `skip_if_same_agent_running = false` for automatic runs unless easy to implement.
+
+Do not build a complete quota engine in v0.1.
+
+---
+
+## 9. Prompt Sending Rules
+
+The scheduler must support sending the configured prompt into the created session.
+
+Prompt source:
+
+1. Inline prompt text.
+2. Prompt file path.
+
+Input mode:
+
+1. Paste mode.
+2. Typed mode.
+
+If only one input mode is easy with Codeman's current internals, implement that first and structure the code so the other can be added later.
+
+Important:
+
+- Do not send prompts to a session if session creation failed.
+- Record prompt-send success/failure in run history.
+- Save enough metadata to understand what prompt was used.
+
+---
+
+## 10. UI Bifurcation
+
+Keep UI changes cleanly separated.
+
+Add scheduler UI under a clear navigation item:
+
+- `Scheduled Jobs`
+
+Do not clutter the existing session dashboard.
+
+The existing session dashboard may show sessions created by scheduled jobs, but the scheduling controls should live in their own section.
+
+Recommended pages/routes:
+
+- `/schedules`
+- `/schedules/new`
+- `/schedules/:id`
+- `/schedules/:id/edit`
+- `/schedules/:id/run-now`
+- `/schedules/:id/enable`
+- `/schedules/:id/disable`
+- `/schedules/:id/delete`
+
+Use Codeman's existing frontend conventions and routing style.
+
+---
+
+## 11. Backend Bifurcation
+
+Keep scheduler code separate from existing session code.
+
+Recommended logical modules, adapted to Codeman's actual structure:
+
+- `scheduler/model` or equivalent.
+- `scheduler/store` or equivalent.
+- `scheduler/service` for schedule calculations and launch logic.
+- `scheduler/loop` for the background due-job checker.
+- `scheduler/routes` for API/UI endpoints.
+- `scheduler/time` for next-run calculations.
+
+Do not mix scheduling logic directly into terminal rendering, xterm handling, or low-level tmux code.
+
+The scheduler service should call session services; it should not own tmux directly unless Codeman has no session abstraction.
+
+---
+
+## 12. Required Discovery Phase Before Coding
+
+Before implementing, inspect the Codeman repo and produce a short architecture note in the terminal or in a file called:
+
+`docs/cron-discovery.md`
+
+This note must identify:
+
+1. Where session creation happens.
+2. Where agent/session types are defined.
+3. Where input is sent into a session.
+4. Where active sessions are listed.
+5. Where session kill/delete is handled.
+6. How session state is stored.
+7. Whether there is existing persistence.
+8. Where backend routes live.
+9. Where frontend pages/components live.
+10. The smallest integration points for scheduling.
+
+Do not start coding until this discovery is complete.
+
+---
+
+## 13. Implementation Phases
+
+### Phase 1: Discovery
+
+Deliverable:
+
+- `docs/cron-discovery.md`
+
+Must answer the 10 discovery questions above.
+
+### Phase 2: Data Model / Persistence
+
+Deliverable:
+
+- Scheduled job persistence.
+- Scheduled run history persistence.
+- Basic create/read/update/delete operations.
+
+### Phase 3: Scheduler Calculation Logic
+
+Deliverable:
+
+- Functions to compute `next_run_at` for:
+  - once
+  - interval
+  - daily
+  - weekly
+
+Add tests if the repo has an existing test setup.
+
+### Phase 4: Manual Run Now
+
+Deliverable:
+
+- Create scheduled job.
+- Click Run Now.
+- Codeman session is created.
+- Prompt is sent.
+- Run history is recorded.
+- UI links to the session.
+
+This is the most important milestone.
+
+### Phase 5: Background Scheduler Loop
+
+Deliverable:
+
+- Enabled schedules launch automatically when due.
+- Run history is recorded.
+- `last_run_at` and `next_run_at` update.
+- Duplicate launch guard exists.
+
+### Phase 6: UI Polish Only After Functionality
+
+Deliverable:
+
+- Scheduled jobs list is readable.
+- Create/edit form is usable.
+- Status labels are clear.
+- Errors are visible.
+
+Do not polish before Phase 4 works.
+
+---
+
+## 14. Acceptance Criteria
+
+The build is acceptable when all these pass.
+
+### Manual Run
+
+1. Create a schedule/job with inline prompt.
+2. Click Run Now.
+3. A new Codeman/tmux session starts.
+4. Prompt is sent into that session.
+5. The created session is visible in Codeman's normal session UI.
+6. Run history shows success or failure.
+
+### One-Time Schedule
+
+1. Create a one-time schedule 2 minutes in the future.
+2. Wait for it to become due.
+3. Scheduler launches a session.
+4. Prompt is sent.
+5. Schedule does not repeatedly launch forever.
+
+### Interval Schedule
+
+1. Create interval schedule every 2 minutes.
+2. It launches once when due.
+3. It computes the next due time.
+4. It does not launch duplicates for the same due time.
+
+### Daily Schedule
+
+1. Create daily schedule at a time a few minutes ahead.
+2. It launches when due.
+3. Next run becomes tomorrow at the same time.
+
+### Disable Schedule
+
+1. Disable a schedule.
+2. It does not launch even when due.
+
+### Error Handling
+
+1. Invalid working directory produces visible error.
+2. Invalid prompt file produces visible error.
+3. Failed session launch creates failed run-history entry.
+
+---
+
+## 15. Explicitly Out of Scope for v0.1
+
+Do not implement these unless all required scope is already working:
+
+- Full quota engine.
+- Advanced lock manager.
+- Post-run git inspection reports.
+- Complex recurring calendar UI.
+- User accounts / RBAC.
+- External distributed workers.
+- Redis.
+- Postgres.
+- Celery.
+- Kubernetes.
+- A separate Python service.
+- Full visual cron editor.
+- AI-generated follow-up prompts.
+- Automatic continuation after idle.
+- Any attempt to bypass agent quotas or platform limits.
+
+---
+
+## 16. Quality Rules
+
+Follow these rules while coding:
+
+1. Reuse existing Codeman services and conventions.
+2. Keep scheduler code isolated.
+3. Prefer boring, readable code over clever abstractions.
+4. Add error messages that a human can understand.
+5. Do not break existing Codeman sessions.
+6. Do not rename existing core concepts unnecessarily.
+7. Do not introduce large dependencies without strong reason.
+8. Keep v0.1 local-first and single-instance.
+9. Commit in logical chunks if git is available.
+10. After coding, provide a final implementation summary.

+
+## 17. Final Response Required from Claude Code
+
+At the end, report:
+
+1. Files changed.
+2. New routes/pages added.
+3. New data structures added.
+4. How the scheduler loop works.
+5. How to run the app.
+6. How to test manual Run Now.
+7. How to test scheduled execution.
+8. Known limitations.
+9. Suggested v0.2 improvements.
+
+---
+
+## 18. v0.2 Ideas, Not for Current Build
+
+Keep these in mind but do not build unless v0.1 is complete:
+
+- Quota-aware scheduling.
+- Manual takeover locks.
+- Post-idle inspection.
+- Git diff reports.
+- Schedule groups.
+- Prompt templates.
+- Agent-specific concurrency rules.
+- Better timezone support.
+- Audit events.
+- More advanced cron expressions.
+
+---
+
+## 19. Final Reminder
+
+The goal is to add **scheduling** to Codeman quickly and cleanly.
+
+Do not drift into building a new platform.
+
+The highest-priority path is:
+
+1. Discover existing Codeman integration points.
+2. Add scheduled job persistence.
+3. Add Run Now.
+4. Add background due-job loop.
+5. Add minimal UI.
+6. Verify that scheduled jobs create real Codeman/tmux sessions and send prompts.

+# CRON_DISCOVERY.md
+
+Phase 1 deliverable for the "Add Scheduling to Codeman" build brief.
+This documents the existing Codeman architecture and the smallest integration
+points for a cron. **No session/tmux logic will be rebuilt** —
+the new code is purely a trigger + persistence + history layer on top of the
+existing primitives.
+
+Stack: `aicodeman` v1.2.1 — Fastify 5 backend, `node-pty` + tmux sessions,
+vanilla-JS SPA frontend served as static assets, JSON file state store, zod
+validation, ports-based dependency injection.
+
+---
+
+## 0. Critical finding: an existing `ScheduledRun` is NOT a cron
+
+Codeman already has a `ScheduledRun` concept (`/api/scheduled`,
+`src/web/ports/infra-port.ts:14-26`, `src/web/server.ts:1480-1605`). It is a
+**run-now, duration-bounded autonomous loop**: given `{prompt, workingDir,
+durationMinutes}` it immediately spawns/kills throwaway sessions in a loop until
+the duration elapses. It has **no** time-based triggering, recurrence
+(once/interval/daily/weekly), enable/disable, next-run calculation, run history,
+or persistence across restarts.
+
+Therefore the brief's core (the calendar/cron trigger layer) does **not** exist
+and must be built. The execution primitives it sits on top of **do** exist and
+will be reused. To honor brief §16 ("do not rename existing core concepts"), the
+new feature is named **`CronJob`** (with **`CronJobRun`** history
+records), kept distinct from the existing `ScheduledRun`.
+
+---
+
+## 1. Where session creation happens
+
+- Canonical create flow: `POST /api/sessions`,
+  `src/web/routes/session-routes.ts:262-438`.
+  - `new Session({ workingDir, mode, ... })` (`src/session.ts:421-570`)
+  - `ctx.addSession(session)` → `ctx.setupSessionListeners(session)` →
+    `ctx.persistSessionState(session)` (all via `SessionPort`).
+- `SessionPort` interface: `src/web/ports/session-port.ts:8-16`.
+- **Integration point:** the cron service will mirror this exact sequence
+  (create → addSession → setupSessionListeners → start) via `SessionPort`,
+  not reimplement it.
+
+## 2. Where agent/session types are defined
+
+- `type SessionMode = 'claude' | 'shell' | 'opencode' | 'codex' | 'gemini'`
+  (`src/types/session.ts:43-44`). `shell` covers the brief's "Terminal/custom".
+- CLI availability resolvers in `src/utils/{claude,codex,gemini,opencode}-cli-resolver.ts`.
+- **Integration point:** the job's `agentType` reuses `SessionMode` verbatim.
+
+## 3. Where input is sent into a session
+
+- Raw / paste: `session.write(data)` (`src/session.ts:2243-2247`) — direct PTY write.
+- Typed (recommended): `session.writeViaMux(data)` (`src/session.ts:2301-2311`)
+  — tmux `send-keys`, falls back to PTY. Submit requires trailing `\r`.
+- **Integration point:** prompt delivery uses `writeViaMux` (typed) by default,
+  `write` (paste) as the alternate `input_mode`.
+
+## 4. Where active sessions are listed
+
+- `ctx.sessions: ReadonlyMap<string, Session>` (`SessionPort`).
+- Filters: `Array.from(ctx.sessions.values()).filter(s => s.mode === X)` and
+  `.isBusy()` / `.isIdle()` (`src/session-manager.ts:220-247`).
+- **Integration point:** the §8 multi-session warning queries this map.
+
+## 5. Where session kill/delete is handled
+
+- `ctx.cleanupSession(sessionId, killMux?, reason?)`
+  (`SessionPort`; impl `src/web/server.ts:997-1152`). Underlying
+  `session.stop(killMux)` at `src/session.ts:2498-2585`.
+- The cron does **not** kill sessions it launches (the brief wants them
+  visible in the normal session UI); cleanup stays user-driven.
+  _Superseded post-review:_ recurring jobs now default to
+  `autoClosePreviousSession: true` — the previous run's still-open session is
+  closed via `cleanupSession` when the next run fires (see
+  `docs/cron-guide.md` §8); opt out per job for fully user-driven cleanup.
+
+## 6. How session state is stored / 7. Existing persistence
+
+- JSON file store: `~/.codeman/state.json` (+ `state-inner.json` for Ralph).
+  `StateStore` class `src/state-store.ts:71`; `AppState` interface
+  `src/types/app-state.ts:99-114`.
+- Pattern: declare a field on `AppState`, add typed get/set methods on
+  `StateStore` that mutate in-memory state and call the debounced `save()`
+  (500ms debounce, atomic temp-file+rename, `.bak` backup, circuit breaker).
+- **Integration point:** add `cronJobs?: Record<string, CronJob>` and
+  `cronJobRuns?: Record<string, CronJobRun>` to `AppState`, with
+  matching `StateStore` accessors. No new DB (brief §6 forbids Postgres/Redis).
+
+## 8. Where backend routes live
+
+- Route modules: `src/web/routes/*.ts`; barrel `src/web/routes/index.ts`;
+  registered in `WebServer.setupRoutes()` `src/web/server.ts:858-876` with a
+  single `ctx` object from `createRouteContext()` (`src/web/server.ts:553-613`)
+  that satisfies all port interfaces.
+- Validation: zod schemas in `src/web/schemas.ts`, applied via
+  `parseBody(Schema, req.body)` (`src/web/route-helpers.ts:101-111`).
+- Errors: `createErrorResponse(ApiErrorCode.X, msg)` / `ApiResponse`
+  (`src/types/api.ts`), auto-mapped to HTTP status by a `preSerialization` hook
+  (`src/web/server.ts:644-659`).
+- SSE: `ctx.broadcast(SseEvent.X, data)` (`EventPort`,
+  `src/web/sse-events.ts`); frontend mirror in `src/web/public/constants.js`.
+- **Integration point:** new `cron-routes.ts` registered alongside the
+  others; new zod schema; new `SseEvent` constants for job list/run changes.
+
+## 9. Where frontend pages/components live
+
+- Vanilla-JS SPA: single `src/web/public/index.html` + feature mixin files
+  (`Object.assign(CodemanApp.prototype, {...})`). API via `api-client.js`
+  (`_apiJson/_apiPost/_apiDelete`). Build = esbuild minify + content-hash, no
+  bundler (`scripts/build.mjs`).
+- UI is panels/modals toggled by JS classes; forms use `.form-row` / `.modal`
+  conventions (`styles.css`). SSE handler map in `app.js`.
+- **Integration point:** add a new `cron-ui.js` mixin + a panel/modal in
+  `index.html` + nav entry, following the orchestrator/respawn panel pattern.
+
+## 10. Background-loop pattern (for the due-checker)
+
+- Established pattern: `this.cleanup.setInterval(fn, intervalMs, {description})`
+  in `WebServer.start()` (`src/web/server.ts:~1942-1966`), auto-disposed in
+  `WebServer.stop()` via `this.cleanup.dispose()` (`src/web/server.ts:2336`).
+  RalphLoop (`src/ralph-loop.ts:268-286`) shows the self-rescheduling guard idiom.
+- **Integration point:** register a 30s cron tick via `cleanup.setInterval`;
+  no manual shutdown wiring needed.
+
+---
+
+## Smallest integration points (summary)
+
+| New piece | Reuses | Location |
+| --- | --- | --- |
+| `CronJob` / `CronJobRun` types | — (new) | `src/types/cron.ts` |
+| Persistence | `StateStore` / `AppState` | `src/types/app-state.ts`, `src/state-store.ts` |
+| Next-run time math | — (new, pure, unit-tested) | `src/cron/cron-time.ts` |
+| Launch + send prompt | `SessionPort` (`addSession`/listeners/`writeViaMux`) | `src/cron/cron-service.ts` |
+| Background due loop | `cleanup.setInterval` pattern | `src/cron/cron-loop.ts` |
+| Routes + schema | route/ports/zod/SSE patterns | `src/web/routes/cron-routes.ts`, `src/web/schemas.ts`, `src/web/sse-events.ts` |
+| UI | panel/modal/mixin conventions | `src/web/public/cron-ui.js`, `index.html` |
+
+Nothing in the session, tmux, persistence, routing, or SSE subsystems is
+rewritten — the cron is additive and calls existing services.

+# Cron Jobs — User & Operator Guide
+
+Codeman's **Cron** feature lets you save named, recurring jobs that automatically
+spin up a Claude (or shell / OpenCode / Codex / Gemini) session on a schedule and
+feed it a prompt. Think "cron for agent sessions": _"every weekday at 3am, open a
+Claude session in `~/proj` and tell it to update dependencies and open a PR."_
+
+- **UI**: the **⏰ Cron** button in the header → the Cron Jobs modal (`#cronModal`).
+- **API**: `/api/cron/jobs*` and `/api/cron/runs`.
+- **Code**: `src/cron/cron-service.ts`, `src/cron/cron-time.ts`, `src/cron/cron-input.ts`,
+  types in `src/types/cron.ts`, routes in `src/web/routes/cron-routes.ts`,
+  frontend in `src/web/public/cron-ui.js`.
+
+> **Not to be confused with `ScheduledRun` (`/api/scheduled`).** That older,
+> deliberately-separate concept is a _run-now, duration-bounded autonomous loop_
+> (`{prompt, workingDir, durationMinutes}` → spawn/kill throwaway sessions until
+> the duration elapses). It has no recurrence, no saved jobs, and no next-run
+> calculation. The two systems never interact. This guide is only about **Cron
+> jobs** (`Cron*`). See `docs/cron-discovery.md` §0.
+
+---
+
+## 1. Quick start
+
+### In the browser
+
+1. Click **⏰ Cron** in the header.
+2. Click **+ New Job**.
+3. Fill in a **name**, pick an **agent type** and **working directory**, choose a
+   **prompt** (inline text or a file path), pick a **schedule**, and leave
+   **Enabled** on.
+4. **Save**. The job appears in the list with its computed **next run**.
+5. Use **Run Now** to fire it immediately without waiting for the schedule.
+
+### With curl
+
+```bash
+API=http://localhost:3000
+
+# Create a daily job (03:00 server-local time)
+curl -s -X POST "$API/api/cron/jobs" \
+  -H 'Content-Type: application/json' \

+
+## 2. Concepts
+
+| Term                       | Meaning                                                                                          |
+| -------------------------- | ------------------------------------------------------------------------------------------------ |
+| **Cron job** (`CronJob`)   | A saved, named definition: what agent to launch, where, with what prompt, on what schedule.      |
+| **Run** (`CronJobRun`)     | One execution of a job — a history record with a status and a link to the session it created.    |
+| **Schedule type**          | How fire times are computed: `once`, `interval`, `daily`, or `weekly`.                           |
+| **Next run** (`nextRunAt`) | Server-computed epoch-ms of the next fire. `null` when the job is disabled or has no future run. |
+| **Due tick**               | A background loop (every 30s) that launches any enabled job whose `nextRunAt` has passed.        |
+
+A job is essentially a **trigger + persistence + history layer on top of the
+existing session primitives**. When a job fires, the cron service does exactly
+what the "quick start" route does — `new Session(...)` → `addSession` →
+`setupSessionListeners` → `startInteractive()`/`startShell()` → deliver the
+prompt. It does **not** reimplement any tmux/PTY logic.
+
+---
+
+## 3. The job form — every field
+
+These map 1:1 to `CronJobSchema` (`src/web/schemas.ts`) and the `CronJob` type
+(`src/types/cron.ts`).
+
+| Field                      | Required    | Values / limits                                          | Notes                                                                                                                                                                                      |

+
+**Cross-field validation** (`refineCronJob` in `schemas.ts`): the conditional
+fields above are enforced by a Zod `superRefine` on create. A missing dependent
+field (e.g. `scheduleType: "once"` with no `runAt`) is rejected with
+`INVALID_INPUT` and a field-specific message.
+
+> ⚠️ **Update caveat.** `PUT /api/cron/jobs/:id` uses a `.partial()` schema that
+> does **not** re-run the cross-field `superRefine`. To keep partial edits safe,
+> `updateJob()` re-validates the **merged** job against the full `CronJobSchema`
+> and throws `400` if the result is inconsistent (e.g. switching to `once`
+> without a `runAt`). So the store is never left with a half-valid job.
+
+---
+
+## 4. Schedule types
+
+Next-run math lives in `src/cron/cron-time.ts` (pure, unit-tested in
+`test/cron-time.test.ts`). **All wall-clock times use the server's local
+timezone** (v0.1 decision).
+
+### `once`
+
+- Fires a single time at the absolute `runAt` epoch-ms.
+- A **missed** one-time job (server was down at `runAt`) **still fires once** on
+  the next tick — `computeNextRunAt` returns `runAt` even if it's in the past,
+  until the job has fired.
+- After firing, the job **self-disables**: `completedOnce = true`, `enabled =
+false`, `nextRunAt = null`.
+
+### `interval`
+
+- Fires every `intervalMinutes`, computed as `fireTime + intervalMinutes`.
+- ⚠️ **Drift**: the next run re-anchors to the actual fire time, not to an ideal
+  cadence — a slow tick or restart shifts subsequent runs slightly later. This is
+  an accepted limitation.
+
+### `daily`
+
+- Fires at `dailyTime` (`HH:MM`) every day, server-local.
+- If today's time has already passed, the next run is tomorrow at that time.
+
+### `weekly`
+
+- Fires at `weeklyTime` on each weekday in `weeklyDays` (0 = Sunday … 6 =
+  Saturday), server-local.
+- The next run is the soonest upcoming matching weekday/time within the next 7
+  days.
+
+---
+
+## 5. Prompt source (`promptMode`)
+
+### `inline_text`
+
+The prompt is the literal `promptText`. Simplest option.
+
+### `prompt_file_path`
+
+The prompt is read from a file at fire time. **This path is security-hardened**
+because a job config is attacker-controllable and the file's contents are
+injected into an agent session (an exfiltration sink over SSE/terminal).
+`resolveSafePromptPath()` enforces, in order:
+
+1. **`realpath` resolution** — symlinks are resolved to their true target, for
+   the prompt file **and for `workingDir` itself**.
+2. **`workingDir` is not a trust boundary** — because it is user-supplied, the
+   resolved `workingDir` is itself rejected if it is `/` or resolves into a
+   blocked tree (`/etc`, `/root`, operator extras) or a pseudo-filesystem
+   (`/proc`, `/sys`, `/dev`). This closes the `workingDir: '/proc'` +
+   `promptFilePath: '/proc/self/environ'` env-exfil trick. The same rule is
+   enforced earlier, at job create/update.
+3. **Blocklist** (defense-in-depth) — sensitive trees (`/etc`, `/root`,
+   `/proc`, `/sys`, `/dev`, known secret locations) are rejected for the
+   resolved prompt file.
+4. **Allowlist (primary gate)** — the resolved path **must live inside the job's
+   (resolved) `workingDir`** (`validateSessionFilePath`). A symlink escaping the
+   workspace fails here.
+5. **Regular-file check** — directories, FIFOs, and `/dev/*` character devices
+   are rejected (they would hang or OOM an unbounded read).
+6. **Size cap** — files larger than **1 MiB** (`MAX_PROMPT_FILE_BYTES`) are
+   rejected.
+7. **Single-line check** — after trailing newlines are stripped, the file
+   content must be a single line (see §6).
+
+If any check fails, the run is recorded as **`failed`** with the reason; no
+session is created.
+
+---
+
+## 6. Prompt delivery (`inputMode`)
+
+Once the CLI is ready (see §8), the prompt is written to the session with a
+trailing carriage return:
+
+| Mode    | Mechanism                                                       | Use when                                         |
+| ------- | --------------------------------------------------------------- | ------------------------------------------------ |
+| `typed` | `session.writeViaMux()` — tmux `send-keys -l` (literal) + Enter | Default; behaves like a human typing the prompt. |
+| `paste` | `session.write()` — writes directly to the PTY/mux              | Bulk paste-style delivery.                       |
+
+> ⚠️ **Single-line only — enforced.** Like all programmatic input in Codeman,
+> multi-line delivery would be silently corrupted (Ink-based TUIs treat a
+> newline as submit; typed mode fuses lines). So newlines are **rejected**: the
+> schema and the form refuse a multi-line `promptText`, and at fire time a
+> prompt file whose content is multi-line (after stripping trailing newlines)
+> fails the run with a clear `errorMessage`. Put multi-line instructions in a
+> file the agent is told to read itself (e.g. "read TASKS.md and do it").
+
+---
+
+## 7. Concurrency policy (automatic runs)
+
+`concurrencyPolicy` governs what happens when a **scheduled** run is due and
+sessions of the same `agentType` already exist:
+
+| Policy                       | Behavior                                                                                                                                                                 |
+| ---------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| `warn_only`                  | Always launch. (The count is surfaced but not blocking.)                                                                                                                 |
+| `skip_if_same_agent_running` | If ≥ 1 **other, live** session of that mode is active, **skip** this fire — record a `skipped` run and (for recurring schedules) advance the schedule without launching. |
+
+Notes on `skip_if_same_agent_running`:
+
+- Only **live** sessions block: a tab whose CLI already exited (status
+  `stopped`/`error`) does not count.
+- Sessions created by **this job's own previous runs never block it** —
+  otherwise a recurring job would deadlock on the session it created last time
+  and fire exactly once.
+- A skipped **`once`** job is **not consumed**: it stays armed and retries on
+  the next tick until the blocking session goes away, then fires its single run.
+- A skip is **not** a run: it sets `lastStatus = 'skipped'` but does **not**
+  advance `lastRunAt`.
+- Consecutive skips are **coalesced** — a perpetually-skipped interval job writes
+  **one** skip record per streak, not one every tick, so it can't bloat
+  `state.json`.
+
+**Run Now ignores this policy on the server.** The browser shows a `confirm()`
+warning if same-type sessions are active, but if you proceed (or call the API
+directly), the job launches unconditionally.
+
+---
+
+## 8. What happens when a job fires
+
+Sequence in `CronService.launch()`:
+
+1. A `CronJobRun` is created with status **`created`** and broadcast
+   (`cron:runCreated`).
+2. The prompt is resolved (inline or file, single-line enforced). Failure →
+   **`failed`**.
+3. `workingDir` is checked (`statSync().isDirectory()`). Missing/not-a-dir →
+   **`failed`**.
+4. **Auto-close previous session** (recurring schedules, unless
+   `autoClosePreviousSession: false`): any still-open session created by this
+   job's previous runs is closed via the normal session-cleanup path.
+5. The global session cap is checked (`MAX_CONCURRENT_SESSIONS = 50`). At cap →
+   **`failed`**.
+6. A `Session` is created **with `useMux: true`** (so it runs inside tmux),
+   registered, listeners attached, and started via `startInteractive()`
+   (`startShell()` for `shell` mode). Model/claudeMode come from global config.
+   Run status → **`session_started`**.
+7. **Readiness wait** (async, non-blocking): for non-shell agents the service
+   polls the terminal buffer up to **60 × 500ms** for a `❯` prompt or the string
+   `tokens`, then settles **2000ms** (`CRON_READY_SETTLE_MS`). Shell mode waits
+   1000ms, then sends the optional `launchCommand` as the first input line
+   (+1000ms settle).
+8. The prompt is delivered (`typed`/`paste`, trailing `\r`). Run status →
+   **`prompt_sent`**; `finishedAt` stamped. Delivery failure (e.g. the mux
+   session is gone) → **`failed`**.
+
+The created session is a **normal, persistent interactive session** — it appears
+as its own tab and keeps running after the prompt is sent. The run's
+`createdSessionUrl` is a deep link (`/?session=<id>`); the UI focuses it
+automatically after **Run Now**.
+
+> ⚠️ **Session-cap math if you disable auto-close.** With
+> `autoClosePreviousSession: false`, nothing ever closes the sessions a
+> recurring job creates — an interval job every 30 min creates 48 tabs/day and
+> hits the global 50-session cap in ~25 hours (sooner with existing tabs), after
+> which **every** fire of **every** job fails with "Maximum concurrent sessions
+> reached" until you delete tabs by hand. Leave auto-close on for unattended
+> recurring jobs, or clean up sessions yourself.
+
+### The background tick
+
+`tickDueJobs()` runs every **30s** (`CRON_TICK_INTERVAL`, registered in
+`server.ts`). For each enabled job whose `nextRunAt ≤ now`:
+
+- **Duplicate-launch guard**: `lastDueKey = jobId:fireTime`. If this due time was
+  already consumed (overlap/restart), the job is just advanced, not relaunched.
+- The schedule is **advanced _before_ launching** so a slow launch can't be
+  re-triggered by the next tick.
+- On boot, `init()` recomputes `nextRunAt` for loaded jobs (dead `once` jobs stay
+  dead).
+
+---
+
+## 9. Run history & statuses
+
+Each job keeps a history of `CronJobRun` records. Statuses (`CronJobRunStatus`):
+
+| Status            | Meaning                                                       |
+| ----------------- | ------------------------------------------------------------- |
+| `created`         | Run record created; prompt/session not yet started.           |
+| `session_started` | Session launched successfully.                                |
+| `prompt_sent`     | Prompt delivered — the happy-path terminal state.             |
+| `failed`          | Something went wrong (see `errorMessage`).                    |
+| `skipped`         | A scheduled fire was skipped by `skip_if_same_agent_running`. |
+
+Each run also records `triggerType` (`scheduled` or `manual_run_now`),
+`sessionId`/`sessionName`, timestamps, and `createdSessionUrl`.
+
+**History is capped globally** at **500 records** (`MAX_CRON_RUN_HISTORY`); the
+oldest are pruned first. Deleting a job also deletes its run records.
+
+---
+
+## 10. API reference
+
+All responses use the standard `ApiResponse<T>` envelope (`{success, data}` /
+`{success, error, errorCode}`). `/api/v1/*` is a stable alias.
+
+| Method   | Endpoint                     | Body                   | Returns                           |

+
+Emitted on `/api/events`, mirrored in `SSE_EVENTS` (`constants.js`):
+

+| ------------------ | ------------ | -------------------------------------------------------------------- |
+| `cron:jobsChanged` | `{ jobs }`   | Any job created / updated / enabled / status change.                 |
+| `cron:jobDeleted`  | `{ id }`     | A job was deleted.                                                   |
+| `cron:runCreated`  | `CronJobRun` | A run (incl. skips) started.                                         |
+| `cron:runUpdated`  | `CronJobRun` | A run advanced state (`session_started` / `prompt_sent` / `failed`). |
+
+---
+
+## 12. State & persistence
+
+Persisted in `~/.codeman/state.json` via `StateStore`:
+
+- `AppState.cronJobs` — map of `id → CronJob`.
+- `AppState.cronJobRuns` — map of `id → CronJobRun`.
+
+Jobs and their schedules survive restarts; `init()` recomputes `nextRunAt` on
+boot. Sessions the jobs create persist through the normal session-recovery path.

+
+## 14. Known limitations
+
+- **Server-local timezone only** — `daily`/`weekly` times are interpreted in the
+  host's local time; there is no per-job timezone.
+- **Interval drift** — `interval` re-anchors to the actual fire time; long-running
+  intervals slowly shift.
+- **Single-line prompts** — multi-line prompts are rejected (schema, form, and
+  at fire time for prompt files); tell the agent to read a file itself for
+  multi-line instructions.
+- **`runNow` / tick race** — a manual Run Now firing at the same instant as a
+  scheduled tick is theoretically possible; benign (you may get two sessions).
+- **`{enabled:true}` on a dead `once` job** — re-enabling a fired one-time job
+  without changing its schedule leaves it enabled-but-dead (won't fire); change
+  the schedule to re-arm.

+# Docker Session Mode, Implementation Plan
+
+## Decisions (locked 2026-07-19, by repo owner)
+
+1. **Isolation posture**: CONVENIENT default (bind-mount host `~/.claude` etc. read-write so the existing login just works; network on; still hardened non-root + cap-drop + resource caps). SEALED profile (`mountCredentials:false` + `network:none`) is a per-case opt-in.
+2. **Export**: offer BOTH full-image (`commit`+`save`+workspace tar) AND workspace-only, side by side, no default (ask each time).
+3. **Base image**: BUILD LOCALLY on first use via `scripts/build-agent-image.mjs` from a repo `docker/agent.Dockerfile`. No registry required. (GHCR pull can be added later.)
+4. **Hooks**: WIRE HOOKS NOW. Codeman scaffolds `.claude/settings.local.json` + CLAUDE.md into the linked host workspace dir (same as local cases), enabling in-container permission prompts, hook-idle detection, and the Claude Model picker.
+
+Adopted defaults for the remaining open items (Section 10): resume-on-restart ON; container is per-CASE and shared by multiple sessions (killing one session only kills its in-container tmux session, never `docker stop` while siblings remain; stop/remove only on explicit teardown or case-delete); rootless caps = ship-with-warning (`capsEnforced` surfaced); remote docker daemon = local-first; podman = docker-first best-effort.
+
+## Implementation status (branch `feat/docker-session-mode`)
+
+DONE and END-TO-END VERIFIED against a real docker daemon (create host, link case, quick-start shell in a real container, workspace bind-mount round-trip, hook scaffolding, session-delete keeps the shared container up, case-delete `docker rm`s it):
+
+- Phase 0-1: types (`DockerHost`/`DockerCase`/`SessionDocker`), `src/docker-hosts.ts` (storage, pure `buildDockerBaseArgs`/`buildDockerCreateArgs`, `containerApiUrl`, `hostGatewayAlias`, config-hash, credential-mount resolution, daemon probes), `DockerHostSchema`/`DockerCaseLinkSchema`. 26 unit tests.
+- Phase 2: `tmux-manager` `buildDockerLaunchCommand` (image-check -> ensure -> start -> exec, resume-aware), `buildDockerKillCommand` (in-container tmux only, multi-session safe), stop/remove; wired into `createSession`/`respawnPane`/`killSession`. 14 unit tests.
+- Phase 3: `Session` threading (`_docker`, toState, option builders, in-container cliVersion probe, `resolveMuxAttachCwd`), `server.ts` recovery round-trip.
+- Phase 4: `case-routes` `/api/docker-hosts` CRUD + `/api/cases/docker-link` + listing + docker-unlink; `session-routes` `/api/quick-start` docker branch (rejects per-session config, probes availability + tmux, scaffolds hooks, seeds resume id).
+- Phase 5 (partial): `docker/agent.Dockerfile` + `scripts/build-agent-image.mjs` (built + verified: node 22, tmux, claude/codex/gemini/opencode, arbitrary-uid HOME). Host-guard allowlists `host.docker.internal`/`host.containers.internal` for in-container hooks.
+- Full CI green (3445 tests).
+
+REMAINING:
+
+- Phase 6: export / import (`docker commit` + `save | gzip` + workspace tar + manifest; `load` + quarantined re-tag), GC / boot reaper, disk-safety prechecks, drift-recreate route, SSE `docker:*` events. THE "move to a new machine" feature.
+- Phase 7: frontend Create Case "Docker" tab + `linkDockerCase` + run wiring + case-picker labels + export/import UI.
+- Phase 8: CLAUDE.md "Docker cases" Key Pattern + `docs/docker-cases.md` + COM.
+- Deferred refinements: in-container model-picker via `settings.local.json`; live mid-run resume-id capture into `DockerCase.lastClaudeSessionId`; rootless/Desktop uid probe (currently a platform heuristic).
+
+## 1. Goal & user stories
+
+Add "Docker cases" to Codeman: a case can point at a container instead of a local or remote-SSH path, and any of the five CLI backends (`claude` / `shell` / `opencode` / `codex` / `gemini`) runs inside that container. It is modeled as a LOCATION OVERLAY on cases, exactly like the remote-SSH feature (COD-94/#145), never as a sixth `SessionMode`.
+
+User stories:
+
+- As the repo owner, I link a case to a per-project container so an autonomous Claude/Ralph run executes in a hardened sandbox (cap-drop, non-root, resource caps) instead of directly on my host, while keeping my existing OAuth login and transcript history working with zero extra setup.
+- I set default, per-case-changeable container settings (image, network mode, memory/cpu/pids caps) at link time and edit them later, and edits actually take effect through a recreate-on-drift path (see Section 4).
+- I reconnect after a Codeman restart and land back in the SAME running agent with the conversation intact. When the CONTAINER itself was stopped/rebooted/OOM-killed (which destroys the in-container tmux), the next launch RESUMES the last conversation from the bind-mounted transcript rather than starting fresh (durability model in Section 2, Key decision 1).
+- I export a finished run's whole environment (toolchain plus workspace) to a portable, secret-free `.tar.gz`, move it to another machine, and import it back into a fresh case in one click.
+- The container never accumulates: killing the session stops it, deleting the case removes it, and an instance-scoped boot reaper reaps containers whose case is gone.
+
+Non-goals for the MVP: multi-tenant untrusted-code isolation guarantees (Codeman is loopback-default and single-operator, and the agent already runs `--dangerously-skip-permissions` on the host today), Kubernetes/compose orchestration, and per-command ephemeral containers.
+
+## 2. Chosen architecture and why
+
+The design grafts the strongest idea from each of the three proposals:
+
+- Overlay-not-a-mode + faithful remote-SSH mirror (from "Docker Cases as a Location Overlay"): lowest churn, rides the existing quick-start / mux-sessions / state / recovery plumbing.
+- Convenient-but-hardened default with an opt-in sealed profile, plus exec-time name-only secret env (from "Sealed Sandbox"): a strict security improvement over today's on-host execution without the UX tax of forcing an in-container re-login.
+- One-artifact export + in-app import route (from "Container-as-Cargo"): the genuinely new, high-value capability Codeman lacks.
+
+### Key decision 1: persistent per-CASE container, durable in-container tmux, AND resume-on-restart (the two-layer durability model)
+
+Exactly one long-lived container per Docker case, named as a pure slug function `codeman-case-<slug>` (Docker charset `^[a-zA-Z0-9][a-zA-Z0-9_.-]+$`; Codeman already slugs case names for tmux), so create-if-missing and boot recovery are idempotent. PID1 is `sleep infinity` under `--init` (tini reaps zombies and forwards `docker stop`'s SIGTERM); the CLI is NOT the container command. The CLI runs inside a DURABLE in-container tmux on a dedicated socket `-L codeman-docker`, session `codeman-dkr-<id8>`, the direct analog of remote's `-L codeman-remote` / `codeman-ssh-<id8>`.
+
+Two DIFFERENT failure surfaces need two DIFFERENT recovery layers, and conflating them is the central flaw the critic caught:
+
+1. Codeman-PROCESS restart while the container stays up: the in-container tmux is still alive, so `tmux new-session -A` (attach-or-create) reattaches the SAME live agent and the paneCommand is ignored. This is the remote-SSH durability idiom and it works unchanged.
+2. CONTAINER stop / daemon restart / host reboot / OOM-kill: the in-container tmux is GONE (fresh PID1). `new-session -A` will now CREATE a fresh session and run the paneCommand, which would start a brand-new conversation. This is the case the raw plan silently lost. Because the transcript directory is bind-mounted from the host (Key decision 3), the fix is to launch with RESUME: the paneCommand becomes `exec claude --dangerously-skip-permissions --resume <claudeSessionId>` (codex uses `resume <id>`, gemini `--resume <id>`) whenever a captured `claudeSessionId` exists. The `-A` semantics make this self-selecting: the resume flag only ever executes when tmux is actually re-created, which is exactly when the live session was lost. When tmux is still alive (case 1), attach wins and the flag is inert.
+
+Capturing / persisting / reusing the resume id (the missing mechanism the critic flagged): Codeman already learns `Session.claudeSessionId` from transcript correlation (which works here because projHash matches, Key decision 3) and persists it in `SessionState`. We thread that value into `createSessionOptions` / `respawnPaneOptions` for docker so `buildDockerLaunchCommand` can inject the resume flag on any relaunch. To make a NEW Codeman session (new `id8`) re-launched against the same case resume its predecessor's conversation, we ALSO persist `lastClaudeSessionId` on the `DockerCase` record; the quick-start docker branch seeds the new `Session` with it when the `dockerResumeOnStart` setting is on. First-ever launch has no id, so it starts fresh. This is user-decision 7 (default resume behavior).
+
+Reconciling with stop-on-kill and with the `--restart` policy (the internal inconsistency the critic found): the container is created with `--restart no` uniformly (Codeman's idempotent create-if-missing plus boot recovery is the single recovery mechanism; a restart policy would not preserve the conversation anyway because a restarted container gets a fresh PID1/tmux). Boot recovery re-runs `buildDockerLaunchCommand` from the restored `MuxSession.docker` (`docker inspect || docker create; docker start`, then exec with resume), so a host reboot or daemon restart recreates+starts the container and resumes the conversation instead of the session vanishing. `reconcileSessions` (tmux-manager.ts ~1800-1815) must NOT hard-delete a docker session merely because no LOCAL pane exists after the local `-L codeman` server died; docker (like remote) sessions are restored from `mux-sessions.json` and relaunched. This relaunch path is explicitly part of Phase 4/Phase 3 recovery work, not assumed.
+
+Why this over the alternatives: `docker exec` gets SIGHUP and dies when its client TTY closes, so a bare `docker exec claude` restarts the CLI on every reconnect/respawn. The inner tmux plus resume is what makes reconnect idempotent across BOTH failure surfaces. Because this durability is the single most important design point, tmux-in-image is a HARD gated prerequisite (`checkDockerTmuxAvailable`), never a silent fallback to bare exec. Rejected alternatives: ephemeral-per-run or bare-exec containers (no reattach durability); a literal `'docker'` `SessionMode` (touches dozens of switch/enum sites and diverges from the remote overlay precedent, since Docker is a LOCATION orthogonal to the 5 CLI backends).
+
+### Key decision 2: CLI + auth delivery
+
+One prebuilt base image (built once, contains NO secrets): `node:22-bookworm-slim` + `git tmux ripgrep ca-certificates`, `npm i -g @anthropic-ai/claude-code @openai/codex @google/gemini-cli opencode-ai`, an `agent` user, HOME dirs made writable by an arbitrary host uid via the OpenShift "gid 0, group-writable" convention (Key decision 6). Because the toolchain is baked, export is reproducible and needs no network at import time. The image name/namespace/registry and its refresh cadence are user-decision 2 (the `codeman/agent:base` placeholder implies a Docker Hub org the project may not own).
+
+Credentials are delivered ONLY at runtime, two commit-safe channels, default convenient:
+
+- OAuth/config-file CLIs (Claude Max/Pro, gcloud, opencode): bind-mount the host credential dirs read-write (`~/.claude`, `~/.codex`, `~/.gemini` + `~/.config/gcloud`, `~/.config/opencode`) so the common user "just works" with no in-container login. Because these are bind mounts, `docker commit` (which captures only the container's own writable layer, never bind mounts) physically cannot capture them, so exports stay secret-free.
+- API-key CLIs (codex/gemini): exec-time NAME-ONLY `docker exec --env OPENAI_API_KEY --env GEMINI_API_KEY ...` (no `=value`), sourced from Codeman's own process env. Only the key NAME appears in argv (no `ps` leak), and per-exec env is never captured by `docker commit`. This is the technique Codeman already uses via `tmux setenv` for the local Codex/Gemini panes, so it composes with existing machinery.
+
+Per-host `DockerHost.mountCredentials` defaults `true` (convenient); setting it `false` yields a SEALED profile (no host cred mounts, in-container login only) for genuinely untrusted work. CRITICAL sealed-mode export rule (the leak the critic caught): in sealed mode the in-container login writes tokens into the container's OWN writable layer, which `docker commit` DOES capture, so a full-image export of a sealed container would ship credentials. Therefore full-image export is REFUSED for `mountCredentials:false` containers by default; the user may either take a workspace-only export (always safe) or opt into a pre-commit scrub that `docker exec`s `rm -rf ~/.claude ~/.codex ~/.gemini ~/.config/gcloud ~/.config/opencode` inside the container before commit (destructive to the in-container login, which is the point). This is enforced in the export route, not left to a manifest assertion.
+
+Per-session `envOverrides` / `effort` / `codexConfig` / `geminiConfig` / `openCodeConfig` are REJECTED at quick-start exactly like the remote branch (session-routes.ts ~1698-1710). `modelOverride` is the one deliberate difference from remote: because the docker workspace is a REAL bind-mounted host dir that Codeman scaffolds (Key decision 5 and Section 6), `updateCaseModel()` can write the `model` key into `<workspace>/.claude/settings.local.json` and the in-container `claude` reads it, so the App Settings Claude Model picker works for docker cases. `effort` is a `--effort` CLI arg applied only by the local-spawn path we bypass, so it stays rejected (surfaced honestly in the UI, not silently inert). Per-mode command customization goes through `DockerHost.commands.<mode>` (`defaultDockerCommandForMode`, mirror of `defaultRemoteCommandForMode` at remote-hosts.ts:60). NEVER bake secrets into an image layer and NEVER pass a secret via create-time `-e` (both are committed).
+
+Rejected alternative: sealed-by-default. For a single-operator loopback tool where the agent already runs skip-permissions on the host, forcing an in-container OAuth re-login is a UX regression with little real gain. We keep sealed as an opt-in. Rejected alternative: baking a login into the image, which leaks the instant you `docker save`.
+
+### Key decision 3: workspace mount, container CWD, and transcript correlation
+
+Bind-mount the host workspace dir into the container at the SAME absolute path (`dst == src`, mirror the host path), and set both `Session.workingDir` and the container workdir to that host path.
+
+Two problems this solves that the raw proposals got wrong:
+
+- File features: `DockerCase.hostWorkspacePath` is a REAL host directory, so `Session.workingDir = hostWorkspacePath` keeps file-routes, attachments, image-watcher, and previews working on real host bytes (unlike remote, where the path is remote-only and those features no-op). All three proposals wired `casePath = <container path>`; we deliberately diverge and use the host path.
+- Transcript correlation: Claude writes transcripts under `~/.claude/projects/<hash-of-CWD>/`. By mirroring the host path as the container CWD, the projHash computed inside the container equals the host-side hash Codeman's transcript/subagent/workflow watchers expect, so correlation keeps working (and, in turn, feeds the resume-id capture in Key decision 1). A `/workspace`-style fixed dst would break it. Mirror-vs-fixed is user-decision 3.
+
+`resolveMuxAttachCwd` still returns `/tmp` for docker sessions (the LOCAL bash pane only runs `docker exec`; it never needs the workspace as its cwd), mirroring remote.
+
+### Key decision 4: network default and the engine-specific host gateway
+
+Default `bridge` (own netns, NAT egress, no inbound), per-case changeable to `none` (offline shell sandbox; warned because it breaks the API CLIs) or `custom` (a user-defined bridge `codeman-net-<slug>`, the chokepoint for a future egress allowlist). `host` networking and any `-p` inbound publish are structurally unrepresentable in the flag builder and schema. Rationale: every API-backed CLI (Claude, Codex, Gemini) plus npm/git needs egress, so `bridge` is the only sane functional default; `none` is reserved for `shell`.
+
+The host-callback gateway alias is ENGINE-SPECIFIC (the critic's podman finding): Docker uses `host.docker.internal`, Podman uses `host.containers.internal` (Docker's alias only exists on recent podman). A helper `hostGatewayAlias(engine)` returns the right name; Section 2.5, the create args, the `CODEMAN_API_URL` rewrite, and the host-guard allowlist all consume it, and BOTH aliases are added to the allowlist so a mixed fleet keeps working.
+
+### Key decision 5: hooks actually reach the host AND are actually installed
+
+Two independent things must both be true for a hook to fire, and the raw plan wired only the first:
+
+1. Network reachability. Claude Code hooks POST to `$CODEMAN_API_URL` (`curl -sk`). Inside a bridge container `localhost` is the container and prod binds `127.0.0.1`, so we set `--add-host <gatewayAlias>:host-gateway` on create (skipped on Docker Desktop, where the alias is native), add the gateway alias to the host guard, and provide `CODEMAN_API_URL` and the hook secret (below).
+2. Hook INSTALLATION. Hooks live in `<workspace>/.claude/settings.local.json`, written by the quick-start scaffolding block (around session-routes.ts ~1776) that calls `writeHooksConfig()` / `updateCaseModel()`. The raw plan extended the `!remote` guard to `!remote && !docker`, which would SKIP that block and silently disable ALL hooks regardless of networking. For docker the workspace is a REAL bind-mounted host dir, so the scaffolding block MUST run. Precise fix: extend to `!remote && !docker` ONLY the LOCAL-CLI-availability and local-spawn guards (the ones that stat the local binary or build the local spawn command); leave the workspace-scaffolding guard at `!remote` so it runs for docker. This same decision is what makes `modelOverride` work (Key decision 2). Consequence, surfaced as user-decision 4: linking a docker case now WRITES `.claude/settings.local.json` (and the CLAUDE.md scaffold, matching local-case behavior) into the user's real host directory, a behavioral shift from "link a dir" to "link and scaffold a dir."
+
+`CODEMAN_API_URL` derivation (the wrong-scheme bug the critic caught): prod is HTTPS-only on 3000, and `server.ts` (~2000) auto-sets `process.env.CODEMAN_API_URL = ${protocol}://${apiHost}:${port}`. Hardcoding `http://host.docker.internal:3000` fails every hook. Instead a pure helper `containerApiUrl(process.env.CODEMAN_API_URL, engine)` parses the running URL and substitutes ONLY the hostname with `hostGatewayAlias(engine)`, preserving scheme and port (`https://host.docker.internal:3000`). Unit-tested against http, https, non-default ports, and both engines. Passed as create-time `--env CODEMAN_API_URL=<derived>` (case-stable, non-secret).
+
+Hook secret and session attribution:
+- `~/.codeman/hook-secret` is bind-mounted read-only to a container path; `--env CODEMAN_HOOK_SECRET_FILE=<that path>` is create-time (a path is non-secret; the bytes ride the bind mount and are never committed).
+- `CODEMAN_SESSION_ID` (which the generated hooks reference at hooks-config.ts:78-80 to attribute events) plus `CODEMAN_MUX=1` are SESSION-scoped, so they are passed at EXEC time via `docker exec --env CODEMAN_SESSION_ID=<id> --env CODEMAN_MUX=1` (non-secret, value inline is fine, and exec env is not committed). Because a `tmux` session started fresh only inherits the invoking env when it starts the SERVER, the launch chain ALSO runs `tmux -L codeman-docker setenv -g CODEMAN_SESSION_ID <id>` (and `CODEMAN_MUX`) so reattaches and newly created panes see the same values. This mirrors how Codeman already injects per-session env into tmux for the external CLIs.
+
+Hooks-in-MVP-vs-deferred stays user-decision 4; if deferred, docker ships as explicitly hook-degraded and we lean on output-based idle detection through the docker-exec PTY.
+
+### Key decision 6: uid / HOME / rootless enforcement / macOS Docker Desktop
+
+The raw plan showed `--user 1000:1000` in one place and `--user "$(id -u):$(id -g)"` in another and never resolved HOME writability; this section fixes all of it.
+
+- Linux native (docker rootful or rootless): run `--user <hostUid>:0` (host uid, GID 0). The image follows the OpenShift arbitrary-uid convention: `HOME=/home/agent`, and `/home/agent` plus the tool cache dirs (`~/.npm`, `~/.cache`, `~/.config`) are owned `root:0` and group-writable (`chmod -R g+w`, `g+s` on dirs) so a process with GID 0 can write HOME even though its UID is not 1000. This keeps workspace files host-owned (the agent's UID is the host UID) AND keeps HOME writable, so the CLIs actually start.
+- Podman rootless: use `--userns=keep-id` (maps the host uid to the image's `agent` uid inside the container) instead of `--user`, so `/home/agent` is owned by the running user and workspace files are host-owned. This is a real per-engine branch in `buildDockerCreateArgs`.
+- macOS Docker Desktop: `--user <macUid>` (e.g. 501) does not own the image's `/home/agent`, so non-bind HOME writes fail EACCES and the CLIs may not start; Desktop also does its own bind-mount uid translation, provides `host.docker.internal` natively (no `--add-host`), and its VM memory ceiling can cap `--memory`. Detect Desktop via `docker info` (Server OS `linuxkit` / `OperatingString` contains "Docker Desktop") and take a dedicated path: do NOT pass `--user` (run as the image's baked `agent` uid and rely on Desktop's translation for workspace access), skip `--add-host`, and note in the UI that memory caps are subject to the VM ceiling.
+
+Rootless resource-cap enforcement (the silently-inert risk): rootless Docker without cgroup-v2 systemd delegation (`Delegate=yes`) silently IGNORES `--memory`/`--cpus`/`--pids-limit`. The probe checks `docker info` for `CgroupVersion=2` plus rootless plus delegation; if caps cannot be enforced, `checkDockerAvailable` returns `capsEnforced:false` and the link/probe surfaces "resource caps are advisory on this engine." Whether to REQUIRE delegation or ship-with-warning is user-decision 6.

+- `SessionState` gains `docker?: SessionDocker` immediately after `remote?` (line 219). It persists automatically because `SessionState` is structural and `state-store.ts` stores `toState()` verbatim.
+- `src/mux-interface.ts`: add `docker?: SessionDocker` to `MuxSession` (after line 38), `CreateSessionOptions` (after 81), `RespawnPaneOptions` (after 105). `MuxSession.docker` round-trips through `mux-sessions.json` automatically.
+- `src/types/api.ts` `CaseInfo`: add `'docker'` to the `location` union and a `docker?: { hostId; container; image?; path; network }` display block.
+- `src/services/unified-session-service.ts`: add a boolean `docker?` flag on `UnifiedSessionItem` and source rows, set from `MuxSession.docker` presence (mirror the `remote` flag at ~line 200 and the harvest at session-routes.ts:2313).
+
+New state files (all via `dataPath()`, mirroring `remote-hosts.json` / `remote-cases.json`):
+
+- `~/.codeman/docker-hosts.json` (reusable engine/image/network/resource profiles).
+- `~/.codeman/docker-cases.json` (`name -> DockerCase`, including `lastClaudeSessionId`).
+- `~/.codeman/docker-exports/` (dedicated dir for `.image.tar.gz` + `.workspace.tar.gz` + `manifest.json`; never inline in state.json; retention/pruning per Section 5).
+
+No new `state.json` / `mux-sessions.json` files: `SessionState.docker` and `MuxSession.docker` ride the existing serialization.
+
+## 4. Container lifecycle (exact command shapes)
+
+All builders are PURE string functions (directly unit-testable). Host values interpolated into the outer `bash -c "..."` layer (container name, image, workdir, host paths) are `shellescape()`'d and, for user-supplied fields, schema-rejected for `$`/backtick via `NO_SHELL_META`. The escaping chain here is DEEPER than remote's single `ssh '<tmux ...>'`: the whole `docker inspect || docker create <dozens of --mount/--env/shellescaped host paths>` is interpolated into `bash -c "..."` then `JSON.stringify`'d into respawn-pane. This is a known place to get stuck, so it is covered by concrete escaping tests (Section 9), including host workspace paths containing spaces, not just a "we call shellescape" claim.
+
+New in `src/tmux-manager.ts`:
+
+```ts
+const DOCKER_TMUX_SOCKET = 'codeman-docker';
+// 'dkr' letters deliberately FAIL SAFE_MUX_NAME_PATTERN (^codeman-[a-f0-9-]+$),
+// so a Codeman running INSIDE the container never adopts/resizes/respawns our session.
+export function dockerTmuxSessionName(id: string): string { return `codeman-dkr-${id.slice(0, 8)}`; }
+```
+
+`buildDockerBaseArgs(docker)` (pure, in `docker-hosts.ts`, mirror of `buildSshConnectionArgs`) emits the engine prefix tokens: `docker` (or `podman`) + optional `--context <ctx>` or `-H <daemonHost>`. `buildDockerCreateArgs(docker, sessionId)` emits the `docker create` flag array (with the per-engine uid/userns branch from Key decision 6).
+
+IMAGE PRESENCE (before any create, the auto-pull footgun the critic caught): the launch chain runs `docker image inspect <image> >/dev/null 2>&1` first; on miss it exits with a distinct message ("base image <ref> not present: build with scripts/build-agent-image.mjs or pull it") rather than triggering a blocking multi-GB auto-pull inside the tmux pane. `docker create` carries `--pull=never`. The tmux-availability probe likewise uses `docker run --rm --pull=never <image> sh -lc 'command -v tmux'` and reports the same build/pull hint if the image is absent, so the 15s-bounded probe never hangs on a pull.
+
+CREATE (the ensure step, embedded in the launch string):
+
+```
+docker create \
+  --name codeman-case-myproj --hostname myproj \
+  --label codeman.managed=1 --label codeman.instance=<CODEMAN_INSTANCE> \
+  --label codeman.case=myproj --label codeman.session=<id8> \
+  --label codeman.confighash=<hash> \
+  --pull=never --init --restart no \
+  --user 1000:0 \
+  --workdir '/home/arkon/cases/myproj' \
+  --mount type=bind,src='/home/arkon/cases/myproj',dst='/home/arkon/cases/myproj' \
+  --mount type=bind,src='/home/arkon/.claude',dst='/home/agent/.claude' \
+  --mount type=bind,src='/home/arkon/.codeman/hook-secret',dst='/home/agent/.codeman/hook-secret',readonly \

+  --env CODEMAN_HOOK_SECRET_FILE=/home/agent/.codeman/hook-secret \
+  codeman/agent:base \
+  sleep infinity
+```
+
+- `--user 1000:0` shown is the Linux-native form with GID 0 (Key decision 6); it is actually `--user <hostUid>:0`, or `--userns=keep-id` for podman rootless, or omitted on Docker Desktop. The literal is illustrative only.
+- Create-time `--env` carries only NON-SESSION, non-secret, case-stable values (safe to be committed): the DERIVED `CODEMAN_API_URL` (https-preserving, Key decision 5) and the hook-secret FILE PATH. `CODEMAN_SESSION_ID`/`CODEMAN_MUX` and the codex/gemini key NAMES are exec-time only.
+- `codeman.instance=<CODEMAN_INSTANCE>` is REQUIRED on the label set so the boot reaper is instance-scoped (a beta/second instance must never reap prod's containers).
+- `codeman.confighash` is a stable hash of the drift-relevant create args (image, resources, network, mounts, non-session env). Drift detection (user story 2, the config-never-takes-effect gap): on launch the ensure block compares the desired hash to the existing container's label; on mismatch the launch does NOT silently reuse the stale container. Instead the docker route returns a "container config changed, recreate?" action (SSE + UI confirm), and on confirm Codeman `docker rm`'s and recreates. rm destroys in-image (non-bind) state, but the workspace and transcripts survive on their bind mounts and the conversation is restored via `--resume`, so the recreate is safe. Auto-recreate-vs-prompt is a UI choice; the MVP prompts.
+- `--restart no` (resolved consistently with Key decision 1; recovery is Codeman's idempotent create-if-missing, not an engine restart policy, which also matters for Podman which has no daemon).
+
+EXEC (`buildDockerLaunchCommand`, the docker analog of `buildRemoteLaunchCommand`, TTY-correct, resume-aware). The whole thing is ONE `bash -c` string that image-checks, ensures, starts, primes tmux env, then execs:
+
+```
+docker image inspect codeman/agent:base >/dev/null 2>&1 || { echo 'Codeman: base image codeman/agent:base not present (build or pull it)'; exit 1; } ; \
+docker inspect codeman-case-myproj >/dev/null 2>&1 || docker create <all create args above> ; \
+docker start codeman-case-myproj >/dev/null 2>&1 || { echo 'Codeman: container codeman-case-myproj failed to start (daemon down?)'; exit 1; } ; \
+exec docker exec -it \
+  --workdir '/home/arkon/cases/myproj' \
+  --env TERM=xterm-256color --env COLORTERM=truecolor \
+  --env CODEMAN_SESSION_ID=1a2b3c4d --env CODEMAN_MUX=1 \
+  --env OPENAI_API_KEY --env GEMINI_API_KEY \
+  codeman-case-myproj \
+  sh -lc 'tmux -L codeman-docker setenv -g CODEMAN_SESSION_ID 1a2b3c4d \; setenv -g CODEMAN_MUX 1 \; new-session -A -s codeman-dkr-1a2b3c4d -c '\''/home/arkon/cases/myproj'\'' '\''cd /home/arkon/cases/myproj && exec claude --dangerously-skip-permissions --resume <claudeSessionId>'\'' \; set -t codeman-dkr-1a2b3c4d status off \; set -t codeman-dkr-1a2b3c4d mouse off \; set -t codeman-dkr-1a2b3c4d prefix C-q \; set -s escape-time 0'
+```
+
+- `docker exec -it`: `-t` allocates a PTY and forwards SIGWINCH into the container so the Ink TUI re-lays-out on pane resize; `TERM`/`COLORTERM` prevent degraded rendering. `--env OPENAI_API_KEY` (name only) is present only for codex/gemini and is exec-time (never committed). `CODEMAN_SESSION_ID`/`CODEMAN_MUX` are exec-time values plus a `tmux setenv -g` prime so reattaches and new panes inherit them (Key decision 5).
+- `--resume <claudeSessionId>` (codex `resume <id>`, gemini `--resume <id>`) is appended to `modeCommand` ONLY when a captured id exists; on first launch it is omitted. `new-session -A` makes the flag inert on a live-tmux reattach and effective only when tmux is re-created (Key decision 1).
+- `modeCommand = docker.commands?.[mode] || defaultDockerCommandForMode(mode)` (`exec claude --dangerously-skip-permissions`, `exec bash -l`, etc.), with the resume suffix injected by the builder.
+- Escaping survives every layer identically to remote in shape but deeper in nesting: `paneCommand` (`cd ... && exec ...`) is one shellescaped tmux arg, the whole `tmuxInvocation` is one shellescaped `sh -lc` arg, and the outer string is `JSON.stringify()`'d into `bash -c` by respawn-pane (tmux-manager.ts:1329).
+
+Wire-up (extend the two existing seams to 3-way):
+
+- createSession (tmux-manager.ts:1276): `const fullCmd = docker ? buildDockerLaunchCommand({ mode, docker, sessionId, resumeSessionId }) : remote ? buildRemoteLaunchCommand({ mode, remote, sessionId }) : localFullCmd;`
+- launchCmd cd-skip (tmux-manager.ts:1327): `const launchCmd = (remote || docker) ? fullCmd : \`cd ${JSON.stringify(workingDir)} && ${fullCmd}\`;`
+- respawnPane: same two edits at lines 1524 and 1542.
+
+START / reattach-after-reboot: the ensure block (image-check, `docker inspect || docker create`, `docker start`) is fully idempotent, so boot recovery just re-runs `buildDockerLaunchCommand` from the restored `MuxSession.docker` with the persisted resume id. A rebooted host recreates the container and resumes the conversation.
+
+DOCKER-DOWN surfacing (the PTY-exit-breaker false-trip risk): if `docker start` or `docker exec` cannot attach (daemon down, container missing), the launch prints a docker-specific message and exits, which alone would still count toward `session-pty-exit-breaker` and show a generic "respawn breaker tripped" push. To avoid masking the cause, the docker reattach path runs a fast `checkDockerAvailable` pre-flight: if the daemon/container is unreachable, Codeman broadcasts a docker-specific error (SSE + push, "container <name> is not running / daemon down") and SKIPS the auto-reattach that would trip the breaker, rather than fast-looping `docker exec`.
+
+STOP / KILL (`killSession` Strategy 3c, right after remote's Strategy 3b at tmux-manager.ts:1719, guarded by `IS_TEST_MODE`):
+
+```ts
+if (session.docker) {
+  // best-effort, fire-and-forget, timeout-bounded so it never blocks the local kill
+  execAsync(buildDockerKillCommand({ docker: session.docker, sessionId }), { timeout: EXEC_TIMEOUT_MS }).catch(() => {});
+}
+```
+
+`buildDockerKillCommand` emits: `docker exec codeman-case-<slug> tmux -L codeman-docker kill-session -t codeman-dkr-<id8> ; docker stop -t 10 codeman-case-<slug>`. Stopping frees CPU/RAM and, per Key decision 1, is safe for conversation continuity because the NEXT launch resumes from the bind-mounted transcript via `--resume`. Whether to stop at all (RAM vs instant live-agent reattach) is user-decision 6/1 (reframed honestly). The bind-mounted workspace and transcripts always survive on the host.
+
+REMOVE: only on explicit case delete (`docker rm -f codeman-case-<slug>`), gated behind an "export first?" UI prompt because rm destroys any in-image (non-bind) state. Instance-scoped boot reaper (fixing the racy/cross-instance reaper): after `docker-cases.json` is loaded AND after `restoreMuxSessions` has run, enumerate `docker ps -a --filter label=codeman.managed=1 --filter label=codeman.instance=<CODEMAN_INSTANCE> --format '{{.Names}}\t{{index .Labels "codeman.case"}}'` and `docker rm -f` only containers whose case is gone from THIS instance's `docker-cases.json`. The instance filter is what stops a beta reaping prod's containers (the exact cross-instance hazard the project memory warns about).
+
+AVAILABILITY PROBE (`docker-hosts.ts`, timeout-bounded like `checkRemoteTmuxAvailable`'s 15s, `IS_TEST_MODE` no-op):
+
+```
+docker info --format '{{json .}}'                                  # server up, CgroupVersion, rootless, OS (Desktop detect), cap-delegation
+docker image inspect <image> --format '{{.Id}}'                    # image PRESENT (no auto-pull)
+docker run --rm --pull=never <image> sh -lc 'command -v tmux'      # tmux-in-image gate (hard prerequisite), only if image present
+```
+
+`checkDockerAvailable()` returns `{ ok, engine, rootless, isDesktop, cgroupV2, capsEnforced }` (parse `SecurityOptions` for `name=rootless`, `CgroupVersion`, delegation, and Server OS for Desktop). `checkDockerTmuxAvailable(host)` returns a structured result with a user-facing error and correct install hint (NOT `npm install -g`; the hint is "build/pull the base image" for a missing image and "install docker or podman" for a missing engine).
+
+IN-CONTAINER CLI VERSION (fixing the #154 wheel-forwarding regression): the raw plan skipped the LOCAL `cliVersion` probe for docker (correct, since it reports the HOST claude) but left `cliVersion` undefined, which disables trackpad wheel-forwarding. Instead, for docker sessions Codeman runs an IN-CONTAINER probe `docker exec <container> claude --version` (bounded, `IS_TEST_MODE` no-op) and feeds THAT into `cliVersion`. This also means a stale baked CLI is visible; combined with the rebuild-cadence in user-decision 2, agents are not silently pinned to an old claude.
+
+## 5. Export / Import
+
+EXPORT is a concurrency-bounded job (reuse `runWithConversionLimit` from `document-conversion-limiter.ts` so N simultaneous exports cannot fork-bomb the host). Route `POST /api/docker-cases/:name/export`.
+
+Preconditions (the consistency and leak risks the critic caught):
+- Sealed guard: if `mountCredentials:false`, full-image export is REFUSED unless the caller explicitly opts into the pre-commit scrub (Key decision 2). Workspace-only export is always allowed.
+- Quiesce + free-space: require the session idle, then `docker pause` the container spanning BOTH the workspace tar AND the commit so the two artifacts are mutually consistent (the raw plan paused only the commit, leaving the bind-mount tar to run against a mid-write agent). Before any heavy step, precheck free space in the exports dir and in `/var/lib/docker`; if below `DOCKER_EXPORT_MIN_FREE_BYTES`, refuse with a clear error (a full `/var/lib/docker` wedges the daemon and breaks EVERY session on the host).
+
+Steps (all cleanup in try/finally so a mid-way failure never orphans an intermediate image or leaves the container paused):
+
+1. `docker commit -c 'LABEL codeman.exported=1' codeman-case-<slug> codeman/export-<slug>:<ts>` (unique tag per export defeats the stale-image trap). Optional pre-commit scrub in sealed mode as above; also blank instance-specific committed env (`-c 'ENV CODEMAN_API_URL='` etc.) so the image carries no stale host references.
+2. `docker save codeman/export-<slug>:<ts> | gzip` streamed in fixed 8192-byte chunks to `~/.codeman/docker-exports/<slug>-<ts>.image.tar.gz`. Uses `docker save` (layers + repo:tag + CMD), never `docker export` (flat rootfs), so restore is a trivial `docker load`.
+3. `tar --numeric-owner -C <hostWorkspacePath> -czf <slug>-<ts>.workspace.tar.gz .` while paused (the bind-mounted workspace is NOT in the image, so it travels separately and consistently).
+4. Write `manifest.json`: schema version, caseName, image tag, engine, containerWorkdir, resource/network config, codeman version, base-image digest, createdAt, per-member sha256, `mountCredentials`, and `secretFree` (true only for convenient-mode or scrubbed-sealed exports).
+5. `docker rmi codeman/export-<slug>:<ts>` in the `finally` (delete the intermediate committed image regardless of success), then `docker unpause`.
+
+The three files are wrapped in one bundle `<slug>-<ts>.codeman-container.tgz` and offered as a downloadable artifact through the existing file-routes streaming + attachment-registry handoff.
+
+Retention / disk budget (user-decision 3): `docker-exports/` is capped at `DOCKER_EXPORT_KEEP` most-recent bundles with an auto-prune on each new export, plus the free-space precheck above. Workspace scrub: the WORKSPACE tar gets a scan/warn pass for agent-created `.env` / `.git/credentials` (a distinct leak channel from container creds). A lighter "workspace-only" export (just the workspace tar, no commit/save) is the fast default for 24h+ runs; full-image is the explicit heavier option (user-decision 7 in the original list, now decision on the default button below).
+
+What travels: the baked toolchain image plus any in-image writes, and the workspace tar. What does NOT travel: bind-mounted credentials (physically excluded from commit) and anything that lived only in a bind mount. Secret-free by construction in convenient mode, and enforced (refuse-or-scrub) in sealed mode.
+
+IMPORT `POST /api/docker-cases/import` (untrusted-bundle containment, the traversal/overwrite risk): stream the uploaded bundle, validate every manifest checksum BEFORE any extraction or load. Extract the workspace tar with `tar --no-absolute-names -C <fresh dir>` PLUS per-entry validation rejecting any member whose normalized path escapes the destination (leading `/` or `..` components). `gunzip | docker load` the image, then RE-TAG the loaded image id into a quarantined namespace `codeman/imported-<slug>:<ts>` and NEVER allow the load to overwrite `codeman/agent:base` or any pre-existing tag (capture the loaded id, ignore the bundle's repo:tag). Create a NEW `DockerCase` pointing at the quarantined image with THIS host's mounts/creds and the manifest's resource/network config, and recreate the container hardened (cap-drop ALL, no-new-privileges, non-root, `--pull=never`, CMD overridden to `sleep infinity`). The destination supplies its own login, so credentials never cross machines. Plus `GET /api/docker-exports` (list) and `DELETE /api/docker-exports/:filename`, all behind Codeman's existing auth / loopback-default / host-guard / Origin-CSRF stack.
+
+## 6. Codeman integration (file-by-file, mirroring the remote-SSH feature)
+
+- `src/types/session.ts`: add `DockerCommandMode`, `DockerEngine`, `DockerNetworkMode`, `DockerResourceLimits`, `DockerHost`, `DockerCase`, `SessionDocker` (Section 3). Add `docker?: SessionDocker` to `SessionState` after line 219. SessionMode (line 44) UNCHANGED.
+- `src/mux-interface.ts`: add `docker?: SessionDocker` to `MuxSession` (38), `CreateSessionOptions` (81), `RespawnPaneOptions` (105).
+- `src/docker-hosts.ts` (NEW, direct mirror of `src/remote-hosts.ts`): `readDockerHosts`/`writeDockerHosts`/`readDockerCases`/`writeDockerCases` (via `dataPath`, including `lastClaudeSessionId` read/write), `defaultDockerCommandForMode` (mirror line 60), `dockerDisplayPath` (`container:/path`, mirror `remoteDisplayPath` at 205), `toSessionDocker(host, case)` (mirror `toSessionRemote` at 212), `buildDockerBaseArgs`/`buildDockerCreateArgs` (per-engine uid/userns branch), `hostGatewayAlias(engine)`, `containerApiUrl(processApiUrl, engine)` (scheme+port-preserving, unit-tested), `checkDockerAvailable`/`checkDockerTmuxAvailable`/`probeDockerCliVersion` (15s-bounded, `IS_TEST_MODE` no-op), a config-hash helper for drift, its own POSIX `shellescape` copy (mirror line 83). `const IS_TEST_MODE = !!process.env.VITEST;` gates every real `docker` invocation.
+- `src/tmux-manager.ts`: add `DOCKER_TMUX_SOCKET`, `dockerTmuxSessionName`, `buildDockerLaunchCommand` (resume-aware, image-check, env-prime), `buildDockerKillCommand` (Section 4). Extend the two `fullCmd` ternaries (1276, 1524) and the two `launchCmd` cd-skips (1327, 1542). Add `killSession` Strategy 3c after 1719. Ensure `reconcileSessions` (~1800-1815) does NOT hard-delete docker sessions on local-tmux death (recovery relaunch path).
+- `src/session.ts`: add `_docker?: SessionDocker` field (mirror `_remote` at 403), constructor arg (477), assignment (550). Thread `docker: this._docker` and `resumeSessionId: this._claudeSessionId` into BOTH `createSessionOptions` and `respawnPaneOptions` in `startInteractive` (1352/1370) and the second path (1740/1750). Emit `docker: this._docker` in `toState()` (1010). Replace the LOCAL cliVersion probe at 1320 for docker with the IN-CONTAINER `probeDockerCliVersion` (do not merely skip it). Extend `resolveMuxAttachCwd(workingDir, remote, docker)` (215) to return `/tmp` when `docker` is set. On claudeSessionId capture, persist it to the owning `DockerCase.lastClaudeSessionId`.
+- `src/web/server.ts`: in `restoreMuxSessions` (2160), add `docker: muxSession.docker ?? savedState?.docker` to the `new Session({...})` call (2195-2216), and skip docker in the same `isExternalCliMode`/Ralph recovery guards as remote. Register the instance-scoped boot reaper to run AFTER docker-cases load and AFTER `restoreMuxSessions`. Ensure `CODEMAN_API_URL` derivation reads the SAME `process.env.CODEMAN_API_URL` the server sets at ~2000.
+- `src/web/schemas.ts`: add `DockerHostSchema` and `DockerCaseLinkSchema` (below). The three mode enums (177/373/705) and `QuickStartSchema` (368) UNCHANGED (docker resolves by `caseName` lookup like remote).
+- `src/web/routes/session-routes.ts`: import the docker helpers from `../../docker-hosts.js`. Add a docker branch in `/api/quick-start` parallel to the remote branch (1686-1720): `readDockerCases` -> find by `caseName` -> `readDockerHosts` -> find by `hostId`; reject `envOverrides`/`effort`/`codexConfig`/`geminiConfig`/`openCodeConfig` (but ACCEPT `modelOverride`, which flows via scaffolded `settings.local.json`); run `checkDockerAvailable` + `checkDockerTmuxAvailable` (image-present, engine, caps-enforced); surface `capsEnforced:false` and Desktop notes; set `casePath = dockerCase.hostWorkspacePath` (REAL host dir), `docker = toSessionDocker(host, dockerCase)`, and seed `resumeSessionId` from `dockerCase.lastClaudeSessionId` when `resumeOnStart`. Extend the LOCAL-availability and local-spawn guards (around 1796/1810) to `!remote && !docker`, but DO NOT extend the workspace-scaffolding guard (~1776, `writeHooksConfig`/`updateCaseModel`), which MUST run for docker. Pass `docker` into `new Session` (1847); `autoConfigureRalph` (1853) gated on `!docker`. Add `docker: m.docker !== undefined ? true : undefined` to the unified harvest (2313).
+- `src/web/routes/case-routes.ts`: import the docker read/write/check helpers + schemas. Add a docker listing loop in `GET /api/cases` (mirror 94-119, `location: 'docker'`, `docker: {...}` via `dockerDisplayPath`). Add `/api/docker-hosts` GET/POST/PUT/DELETE (mirror 168-204) and `POST /api/cases/docker-link` (mirror 206-232; run `checkDockerAvailable`/`checkDockerTmuxAvailable` at link time; broadcast `CaseLinked` with `type: 'docker'`). Add a docker-unlink branch to `DELETE /api/cases/:name` (mirror 288-296; `docker rm -f`; broadcast `CaseDeleted` `type: 'docker-unlinked'`). Add the docker branch to single-case `GET` (mirror 358-368). Add `POST /api/docker-cases/:name/export`, `/import`, `GET/DELETE /api/docker-exports`, and a `POST /api/docker-cases/:name/recreate` (drift confirm) per Sections 4 and 5.
+- `src/web/sse-events.ts` + `src/web/public/constants.js`: reuse `CaseLinked`/`CaseDeleted` for CRUD. Add `docker:exportProgress`, `docker:exportComplete`, `docker:importComplete`, `docker:configDrift`, and `docker:containerError` to BOTH registries (kept in sync per CLAUDE.md).
+- Frontend `src/web/public/index.html` (~1831): add a Docker `modal-tab-btn` next to Remote; add a `#case-docker` panel mirroring `#case-remote` with `dockerCaseName`, `dockerHostWorkspacePath`, `dockerContainer`, `dockerImage`, `dockerHostId`, and an Advanced `<details>` for network mode, resource caps, `mountCredentials`, `resumeOnStart`, and remote daemon. Surface a "scaffolds .claude into this host dir" note (user-decision 4) and a "resource caps advisory on this engine" warning when `capsEnforced:false`.
+- Frontend `src/web/public/session-ui.js`: `formatCasePickerLabel` (48) + `buildCasePickerOptions` (71-73) handle `location === 'docker'` (`name @ container`, add container/image to the search haystack); `resetCaseModalFields` (~1514) add a `dockerFields` array; `switchCaseModalTab` (1573/1580/1597) handle `'case-docker'`; `submitCaseModal` add the docker branch; new `linkDockerCase()` (mirror `linkRemoteCase` at 1689) POSTing `/api/docker-hosts` then `/api/cases/docker-link`, sending omitted optionals as `undefined` (spread `...(x ? {x} : {})`, never `null`, per the Zod `.optional()`-rejects-null gotcha); `runClaude` (520) / `runShell` (702) extend the `location === 'remote'` routing to also match `'docker'`; `runOpenCode`/`runCodex`/`runGemini` (792/846/900) make the `isRemote` checks `isRemoteOrDocker` so local status probes are skipped. In the session-options Summary tab, note that `effort` is inert for docker (rejected) while `model` IS honored via `settings.local.json`.
+- Frontend `src/web/public/panels-ui.js` (425-426): add `caseItem?.docker?.path`/`container` to the case-search fields.

+
+`NO_SHELL_META` (rejects `$`/backtick, schemas.ts:297) is REQUIRED on `image`, `hostWorkspacePath`, `containerWorkdir`, and `container`, because all four reach the outer `bash -c "..."` double-quote layer where `$(...)`/backtick re-expose, exactly the reason `remotePath`/`identityFile` use it. `--privileged` and any `-v /var/run/docker.sock` are structurally unrepresentable (never emitted by the builder, never accepted by the schema).
+
+## 7. Security model
+
+- Hardening flags on every create: `--cap-drop ALL`, `--security-opt no-new-privileges` (NOT auto-set by rootless Docker or Podman, so always explicit), the uid/userns branch of Key decision 6 (never container-root; workspace files stay host-owned and HOME stays writable via GID 0), `--pids-limit` (fork-bomb guard), `--memory` with `--memory-swap == --memory` (real OOM cap), `--ulimit nofile`, `--init`, `--pull=never`. NEVER `--privileged`, NEVER mount the docker socket into the agent container. `--storage-opt size=` is emitted ONLY after the probe confirms overlay2-on-xfs-pquota or btrfs (the AICE-class silently-ignored trap); otherwise it is omitted and the UI does not advertise a size cap. Resource caps are advertised as ENFORCED only when the probe reports `capsEnforced:true`; under non-delegated rootless they are labeled advisory (user-decision 6).
+- Engine: prefer whichever the probe finds, Podman-rootless first for security (a container-root breakout lands as an unprivileged host user). Rootless bind-mount ownership uses `--userns=keep-id` (Podman) vs `--user <hostUid>:0` (Docker), so real per-engine branching lives in `buildDockerCreateArgs`. Docker Desktop takes its own uid path (Key decision 6).
+- Blast radius (the combined-posture the critic asked to surface, user-decision 5): the default convenient profile mounts an arbitrary host workspace dir RW (host-owned, mirrored path) AND host `~/.claude`/`~/.codex`/`~/.gemini`/`~/.config/gcloud`/`~/.config/opencode` RW into a NETWORK-ENABLED container. Container-run agent code can therefore read/modify those host trees and reach the network simultaneously. This is still a strict improvement over today's on-host skip-permissions execution, but the user must accept the combined posture explicitly; the sealed profile plus `network:none` is the mitigation for genuinely untrusted work.
+- Secret handling: creds arrive ONLY as bind-mounted files (default) or exec-time NAME-ONLY `--env` (codex/gemini keys), NEVER as create-time `-e` and NEVER as an image layer. Sealed-mode export is refuse-or-scrub (Section 5), closing the sealed-leak inversion.
+- CLAUDE.md "Multi-CLI prefix discipline": the exec-time name-only env is restricted to the CLI-specific keys per mode (Claude: none with OAuth mount; Codex: `OPENAI_API_KEY`/`CODEX_API_KEY`; Gemini: `GEMINI_API_KEY`/`GOOGLE_*`), never a blanket forward. `envOverrides` is rejected for docker, so the `ALLOWED_ENV_PREFIXES` allowlist is not widened.
+- hook-secret: bind-mounted read-only, referenced via `CODEMAN_HOOK_SECRET_FILE` (a path, non-secret); the secret bytes never enter env or the image. Both `host.docker.internal` and `host.containers.internal` are added to the host-guard allowlist so the in-container hook curl's Host header passes on either engine.
+- Host guard / instance isolation: the in-container tmux socket (`codeman-docker`) and name (`codeman-dkr-<id8>`) deliberately FAIL a container-internal Codeman's `SAFE_MUX_NAME_PATTERN`, so a nested Codeman never adopts our session (unit-asserted). The boot reaper is instance-scoped by the `codeman.instance` label so a beta never reaps prod. Any remote-daemon (`-H`/`--context`) mode is host-root-equivalent and stays strictly behind the existing auth/loopback/host-guard/Origin-CSRF stack.
+- Import containment: untrusted bundles are checksum-validated, extracted with traversal guards, and loaded into a quarantined image namespace (never overwriting the base image), then run with the same hardening.
+
+## 8. Phased implementation (branch: `feat/docker-session-mode`)
+
+Each phase is independently testable; per CLAUDE.md, end-to-end test in the real env before COM. All new docker IO paths carry `const IS_TEST_MODE = !!process.env.VITEST;` and no-op under it; the pure command builders are tested directly.
+
+- Phase 0: base image + engine probe. Author `docker/agent.Dockerfile` (OpenShift arbitrary-uid HOME) and `scripts/build-agent-image.mjs` (build or pull the base image; digest recorded). Add `checkDockerAvailable`/`checkDockerTmuxAvailable`/`containerApiUrl`/`hostGatewayAlias` (IS_TEST_MODE no-op) and `GET /api/docker/status`. Test: probe stub returns available/caps/Desktop flags under VITEST; `containerApiUrl` preserves scheme+port and swaps host per engine; status route returns the envelope.
+- Phase 1: types + storage + schemas. Add all types (Section 3), `src/docker-hosts.ts`, `DockerHostSchema`/`DockerCaseLinkSchema`. Test: `docker-hosts.test.ts` (round-trip incl. `lastClaudeSessionId`, display path, config-hash stability); `docker-exec-options.test.ts` (schema rejects `$`/backtick in image/workdir/container).
+- Phase 2: tmux-manager builders. Add `DOCKER_TMUX_SOCKET`, `dockerTmuxSessionName`, `buildDockerLaunchCommand` (resume-aware, image-check, env-prime), `buildDockerKillCommand`; wire the two ternaries + two cd-skips + Strategy 3c; harden `reconcileSessions` against docker hard-delete. Test (pure strings): adopt-proof name fails `SAFE_MUX_NAME_PATTERN`; image-check precedes create; `new-session -A` idempotent; resume flag present only when a resume id is passed; `--pull=never` present; instance label present; escaping survives `bash -c` -> `docker exec` -> `sh -lc` -> tmux WITH a host workspace path containing spaces.
+- Phase 3: session.ts + mux + recovery. Add `_docker` + `resumeSessionId` threading, in-container cliVersion probe, `resolveMuxAttachCwd`, mux-interface fields, `restoreMuxSessions` passthrough, instance-scoped reaper wiring, claudeSessionId -> `DockerCase.lastClaudeSessionId` persistence, unified flag. Test: `toState()` emits docker; a persisted docker session round-trips through mux/state; a relaunch injects the persisted resume id (mock mux); reaper only targets this instance's orphaned containers.
+- Phase 4: routes + first real e2e. case-routes CRUD + listing + drift-recreate; session-routes quick-start branch (scaffolding RUNS, local-availability guards skip, model accepted, effort/config rejected). Manual e2e on a real docker host: docker-host create -> docker-link -> quick-start; confirm the pane runs `claude` in the container, files land host-owned, a Codeman restart reattaches the SAME live agent, and a `docker stop` followed by relaunch RESUMES the conversation.
+- Phase 5: hooks connectivity + installation. host-gateway (per engine), derived `CODEMAN_API_URL`, hook-secret mount, `CODEMAN_SESSION_ID`/`CODEMAN_MUX` exec-env + tmux setenv, host-guard allowlist, and the scaffolding write into the real workspace. Manual e2e: trigger a permission prompt from inside the container and confirm it surfaces; verify hook payloads carry the right session id. If deferred, ship docker as explicitly hook-degraded and verify output-based idle detection through the docker-exec PTY.
+- Phase 6: export/import + GC + disk safety. quiesce+pause span, free-space precheck, commit+save+gzip + workspace tar + manifest + streaming download; sealed-mode refuse-or-scrub; retention/auto-prune; import with checksum validation + traversal guard + quarantined re-tag; drift-recreate; boot reaper; `runWithConversionLimit` cap; `docker rmi` in finally. Manual e2e: export, `docker load` on a second machine (or fresh case), import, confirm toolchain + workspace restored and NO creds present; attempt a sealed full-image export and confirm it is refused-or-scrubbed; attempt a `../` bundle and confirm it is rejected.
+- Phase 7: frontend. Docker tab, `linkDockerCase`, run wiring, case-picker labels, panels search, caps-advisory + scaffold-warning + effort-inert notes. Verify with Playwright (`waitUntil: 'domcontentloaded'`, 3-4s settle) that the Docker tab renders and a linked docker case appears in the picker.
+- Phase 8: docs + COM. Update CLAUDE.md (a "Docker cases" Key Pattern paragraph mirroring remote-SSH, plus the new state files, routes counts, and the resume/durability model), `docs/docker-cases.md`, then COM per the standard flow.
+
+## 9. Test plan
+
+- Unit (pure, CI-safe, mirror `test/remote-hosts.test.ts` / `test/remote-ssh-options.test.ts`):
+  - `test/docker-hosts.test.ts`: storage round-trip (incl. `lastClaudeSessionId`), `dockerDisplayPath`, `defaultDockerCommandForMode`, `toSessionDocker`, `containerApiUrl` (http/https, custom port, docker vs podman gateway), config-hash stability/drift, `buildDockerCreateArgs` flag ordering (cap-drop/no-new-privileges/memory==memory-swap/instance-label/`--pull=never` present; host/privileged/socket absent; per-engine uid vs `--userns=keep-id`).
+  - `test/docker-exec-options.test.ts`: `buildDockerLaunchCommand`/`buildDockerKillCommand` string shape and escaping through `bash -c` -> `docker exec` -> `sh -lc` -> tmux, including a workspace path with spaces; resume flag present only with a resume id; image-presence check precedes create; `dockerTmuxSessionName` fails `SAFE_MUX_NAME_PATTERN`; schema rejects `$`/backtick in image/workdir/container/name; `linkDockerCase`-shaped bodies with omitted optionals validate (no `null` on the wire).
+  - Probe no-op: `checkDockerAvailable`/`checkDockerTmuxAvailable`/`probeDockerCliVersion` return canned values under VITEST and never spawn.
+- Integration (route tests via `app.inject()`, docker no-op'd): `/api/docker-hosts` CRUD; `/api/cases/docker-link` dup-check + broadcast; `GET /api/cases` includes the docker case with `location: 'docker'`; `/api/quick-start` docker branch rejects `envOverrides`/`effort`/config but ACCEPTS `modelOverride`, runs the workspace-scaffolding path, and constructs a session with `docker` set + seeded resume id; `DELETE /api/cases/:name` docker-unlink; export refuse-or-scrub for sealed; import traversal rejection; reaper instance-scoping (label filter). Pick a unique port only if a live-server test is added (search `const PORT =`; 3150+).
+- Manual end-to-end (real docker daemon, the mandatory "always end-to-end test" gate): build the base image; link a docker case; quick-start `claude`; verify OAuth via the mounted `~/.claude`, transcript correlation (subagent/workflow watchers show the session), host-owned files, and a working permission-prompt hook; reattach after a Codeman PROCESS restart (SAME live agent); `docker stop` then relaunch and confirm conversation RESUME; reboot-equivalent (daemon restart) and confirm boot recovery recreates+resumes; change the host's memory/image and confirm the drift-recreate prompt fires; export (convenient) and confirm the tar `docker load`s with no creds; attempt a sealed full-image export and confirm refuse-or-scrub; import into a fresh case; delete the case and confirm `docker rm -f` plus instance-scoped reaper GC; confirm a docker-down state surfaces a docker-specific error and does NOT trip the generic PTY-exit breaker.
+
+## 10. Open decisions for the user
+
+1. Credential + blast-radius posture (combined). Convenient default bind-mounts host `~/.claude` etc. RW AND an arbitrary host workspace RW into a network-enabled container, so container-run agent code can read/modify those host trees and reach the network at the same time. Recommended: convenient default plus a per-host SEALED opt-in (`mountCredentials:false` + `network:none`) for untrusted work. Please confirm you accept the combined arbitrary-workspace-plus-egress-plus-host-creds posture for the default profile (it is still a net improvement over today's on-host skip-permissions execution).
+2. Base image ownership, registry, and freshness. The `codeman/agent:base` placeholder implies a Docker Hub org the project may not own. Pick the real registry/namespace (GHCR under the repo is the natural fit), decide digest pinning, and set a REBUILD CADENCE so agents are not stuck on a stale baked `claude` (the in-container version probe surfaces staleness, but something must trigger rebuilds). Choose: pull a pinned published image, build locally on first use via `scripts/build-agent-image.mjs`, or both.
+3. Container CWD strategy. Mirror the host workspace path inside the container (recommended: makes transcript projHash correlate, file features and resume capture work) vs a fixed `/workspace` (simpler mount, breaks watcher correlation). Please confirm the mirror approach.
+4. Hooks in the MVP AND workspace scaffolding. Making docker hooks fire requires WRITING `.claude/settings.local.json` (and the CLAUDE.md scaffold) into the user's REAL linked host directory, a behavioral shift from "link a dir" to "link and scaffold a dir." Choose: wire hooks + scaffolding now (Phase 5, recommended, and it also enables the model picker), or ship docker as explicitly hook-degraded (no permission prompts / hook-idle) for v1 and add later. Confirm you are OK with Codeman mutating the linked host workspace.
+5. Session-kill teardown and RESUME (reframed honestly). `docker stop` on session kill is not merely "free RAM vs instant reattach": it destroys the in-container live agent, and the conversation survives ONLY because the next launch runs `--resume` from the bind-mounted transcript. Choose: keep the container running (costs RAM, preserves the exact live in-flight agent) vs stop and rely on `--resume` (frees RAM, may lose uncommitted in-flight tool state). Case-delete always `docker rm -f`.
+6. Rootless enforcement posture. Under rootless without cgroup-v2 systemd delegation, `--memory`/`--cpus`/`--pids-limit` are SILENTLY ignored. Choose: REQUIRE delegation (refuse to link a host that cannot enforce caps) or ship-with-warning ("resource caps are advisory on your engine"). The probe reports `capsEnforced` either way.
+7. Default resume behavior. Should a re-linked or re-run docker case default to resuming its last conversation (`resumeOnStart:true`, using `DockerCase.lastClaudeSessionId`) rather than starting clean? This is the crux of making the durability story real and is the recommended default, but it changes user-visible behavior (a new session in an existing case continues the prior conversation).
+8. Export defaults and disk budget. Default export button: workspace-only (fast, small, files-only, recommended for 24h+ runs) vs full-image (reproducible env, multi-GB). Also set the retention cap (max retained exports), the auto-prune policy, and the free-space threshold below which export is refused (a full `/var/lib/docker` breaks EVERY session on the host, not just docker ones).
+9. Remote docker daemon (`-H ssh://...` / `--context`). Support in the MVP (composes with remote hosts, adds host-root trust surface) or local-daemon-only first.
+10. Podman parity depth. Full `--userns=keep-id` plus Quadlet boot-persistence, or Docker-first with Podman as best-effort and boot-persistence via Codeman's idempotent create-if-missing only. Note the podman host alias is `host.containers.internal`, already handled per engine.

+# Docker cases
+
+Run a case inside an **isolated Docker container** instead of directly on the host. Any number of Codeman sessions can share one container (it is scoped to the case, not the session), so a whole project lives in a sandbox with its own network, resource caps, and filesystem, and you can **export the container to move it to another machine**.
+
+Docker mode is a **location overlay on cases**, the direct analog of [remote SSH cases](./remote-hosts.md): where a remote case runs a local tmux pane doing `ssh host` into a durable remote tmux server, a docker case runs a local tmux pane doing `docker exec -it` into a durable **in-container** tmux server. It is not a separate `SessionMode`, so `claude` / `shell` / `opencode` / `codex` / `gemini` all work inside the container.
+
+## One-time setup: build the base image
+
+The container needs a base image with the agent toolchain (node, the CLIs, git, tmux). Build it locally once:
+
+```bash
+node scripts/build-agent-image.mjs          # builds codeman/agent:base
+# options: --engine docker|podman  --image <ref>  --no-cache
+```
+
+The image is **secret-free**: credentials are delivered at runtime (bind mounts or `docker exec --env`), never baked in, so exports never leak them.
+
+## Quickest path: one-click "Run in Docker"
+
+On the **New case → Create New** tab there's a **🐳 Run in an isolated Docker container** checkbox. Checking it alone is enough: Codeman creates the case folder in `~/codeman-cases/<name>`, spins up a hardened container with sensible defaults (auto-provisioning a shared `default` host), and starts the session inside it. No host/image/network fields to fill in.
+
+Click the checkbox's **Container settings** to optionally tweak the predefined defaults, including a **Template** picker:
+
+| Template | Memory | CPUs | GPUs |
+|----------|--------|------|------|
+| Small | 2 GB | 1 | none |
+| Medium (default) | 4 GB | 2 | none |
+| Large | 8 GB | 4 | none |
+| GPU | 8 GB | 4 | all (needs the NVIDIA container toolkit) |
+
+**Disk is elastic** — the container's storage grows automatically as data flows in; there is no fixed cap (bounded only by host disk). Any tweaked setting creates a dedicated per-case host so it never changes the shared `default`.
+
+## Create a docker case (full control)
+
+App → **New case → Docker** tab:
+
+- **Case Name** / **Workspace Path**: the workspace is a real HOST directory bind-mounted into the container at the same path. Codeman scaffolds `CLAUDE.md` + `.claude/settings.local.json` (hooks) into it, and file previews / attachments work on the real bytes.
+- **Host ID**: a reusable docker host profile (image, network, resources). Reuse the same ID across cases to share settings.
+- **Network**: `bridge` (internet on, default), `none` (fully isolated), or a `custom` bridge.
+- **Advanced**: memory / CPU caps, **Mount host credentials** (on = your existing `~/.claude` login just works; off = a sealed sandbox you log into inside the container), **Resume last conversation on relaunch**.
+
+Then run it like any case (Run Claude / Run Shell / …). The first launch creates the container (`codeman-case-<name>`); subsequent sessions attach to the same one.
+
+Equivalent API:
+
+```bash
+curl -X POST localhost:3000/api/docker-hosts -d '{"id":"local","label":"Local","image":"codeman/agent:base"}'
+curl -X POST localhost:3000/api/cases/docker-link -d '{"name":"sandbox","hostId":"local","hostWorkspacePath":"/home/you/projects/sandbox"}'
+curl -X POST localhost:3000/api/quick-start -d '{"caseName":"sandbox","mode":"claude"}'
+```
+
+## Lifecycle
+
+- **Reconnect after a Codeman restart** lands back in the same live agent (the in-container tmux survives).
+- **Container stop / host reboot** recreates the container and, when a resume id was captured, **resumes** the last conversation from the bind-mounted transcript.
+- **Killing one session** only kills that session's in-container tmux session; the shared container stays up for sibling sessions.
+- **Deleting the case** `docker rm -f`s the container (the bind-mounted workspace on the host survives). An instance-scoped boot reaper removes containers whose case is gone.
+
+## Isolation & security
+
+Every container runs hardened: `--cap-drop ALL`, `--security-opt no-new-privileges`, non-root (`--user <hostUid>:0` so workspace files stay host-owned), `--pids-limit`, `--memory` == `--memory-swap`, `--init`. Never `--privileged`, never the docker socket. The default **convenient** profile bind-mounts host credential dirs read-write so the common login just works (creds stay on the host, never captured by `docker commit`); the **sealed** profile (`mountCredentials:false` + `network:none`) is the opt-in for genuinely untrusted work.
+
+Rootless engines without cgroup-v2 systemd delegation cannot enforce resource caps; linking such a host warns that caps are advisory.
+
+## Export / Import (move to another machine)
+
+**Export** (from the Docker tab, or `POST /api/docker-cases/:name/export`): choose
+
+- **Full image + workspace**: `docker commit` the container to an image, `docker save` it, tar the workspace, and a manifest, all into one portable `<case>-<ts>.codeman-container.tgz` (the whole toolchain, installed packages, and files). Runs in the background; you are notified when the bundle is ready.
+- **Workspace only**: just the project files (fast, small).
+
+The container is paused across the capture so the image and workspace are consistent; a full `/var/lib/docker` is guarded against with a free-space precheck; the intermediate image is always cleaned up.
+
+**Import** (`POST /api/docker-cases/import`, or the Manage tab): copy the `.tgz` onto the new machine's `~/.codeman/docker-exports/`, then import it into a new case. The manifest and per-member SHA-256 checksums are validated, the workspace tar is extracted with a path-traversal guard, and the image is `docker load`ed and **re-tagged into a quarantined namespace** (`codeman/imported-<case>:<ts>`) so it never overwrites a local tag. The destination supplies its own credentials, so nothing secret crosses machines.
+
+`GET /api/docker-exports` lists bundles; `GET /api/docker-exports/:filename` downloads one; `DELETE` removes one.
+
+## Hooks require the server to be reachable from the container
+
+In-container hooks (permission events, hook-based idle/stop/task notifications) POST to `CODEMAN_API_URL`, which is derived as `https://host.docker.internal:<port>` (`host.docker.internal` → the docker bridge gateway, e.g. `172.17.0.1`, via `--add-host …:host-gateway`). For that callback to succeed, the Codeman server must be **listening on an interface the container can reach**.
+
+- If Codeman binds **loopback-only** (`127.0.0.1`, the default and the production systemd config), a container reaching `172.17.0.1:<port>` cannot connect, so by default **in-container hooks do not fire**. The session still works fully: idle/stop detection falls back to **output-based** detection through the `docker exec` PTY (which always works), and claude runs with `--dangerously-skip-permissions` so there are no permission prompts to forward anyway.
+- **To enable in-container hooks on a loopback-only server, set `CODEMAN_DOCKER_BRIDGE_HOOKS=1`** (env). Codeman then starts a SECOND listener bound to the docker bridge gateway (`172.17.0.1`, auto-detected; override with `CODEMAN_DOCKER_BRIDGE_HOST`) that serves **only the hook endpoints** (`/api/hook-event`, `/api/status-telemetry`) and delegates them into the same secret-gated pipeline. The bridge is host-internal (containers + host, not the LAN), and every other path returns `403`, so this does not widen your network exposure. Add `Environment=CODEMAN_DOCKER_BRIDGE_HOOKS=1` to the systemd unit and restart.
+- Alternatively, bind `0.0.0.0` **with `CODEMAN_PASSWORD` set** (exposes on the LAN too).
+
+The host-gateway mapping, `CODEMAN_API_URL` derivation, host-guard allowlist, and hook-secret mount are all wired correctly; `CODEMAN_DOCKER_BRIDGE_HOOKS` closes the last gap for loopback-only servers.
+
+## Notes & limits
+
+- Requires Docker (or Podman) with a reachable daemon; tmux must be present in the base image (a hard prerequisite, probed at link time).
+- Per-session `envOverrides` / `effort` / per-CLI config are rejected for docker cases (they do not cross into the container); configure the container via the docker host's per-mode command override instead.
+- macOS Docker Desktop takes a dedicated uid path (the baked image uid; memory caps are subject to the VM ceiling).

+# Reliable input delivery (exactly-once, durable)
+
+## The bug this fixes
+
+With local echo on, pressing Enter cleared the overlay and then sent the prompt
+over the WebSocket **fire-and-forget** (`ws.send({t:'i',d})`). On a flaky link
+(e.g. a moving train) the socket is frequently *half-open*: `readyState === OPEN`
+so `ws.send()` does **not** throw, but the underlying TCP is dead, so the frame is
+silently discarded. Nothing was enqueued (the send "succeeded"), the on-screen
+prompt was already wiped, and `navigator.onLine` stays `true` — so a long typed
+prompt vanished with no trace and no resend.
+
+## The guarantee
+
+Every byte of user input is **recorded durably before delivery** and **only
+dropped once the server ACKs it** — so a half-open socket, a reconnect, or a page
+reload can never lose input. Redelivery is **exactly-once**: the server applies
+each `(clientId, seq)` at most once, so a resend can't type the prompt twice.
+
+## How it works
+
+### Client (`app.js`)
+
+- A stable **`clientId`** (`localStorage['codeman:clientId']`) identifies this
+  browser to the server's dedup across reconnects and reloads.
+- Each input frame gets a **monotonic per-session `seq`**. Frame records
+  (`{seq,data,useMux,ts,tries,sentAt}`) live in `_pendingDeliveries`
+  (`Map<sessionId, record[]>`), persisted (debounced, + flushed on `pagehide`/
+  `visibilitychange`) to `localStorage['codeman:pendingInput']`. The seq counters
+  persist too, so seqs stay monotonic across reloads (never reset — a reset would
+  let the server treat fresh input as an already-applied duplicate).
+- **Delivery** (`_drainSession`):
+  - **WS path** — when the socket is `OPEN` for the session, send each not-yet-sent
+    record (`sentAt === 0`) in seq order over the single ordered stream. Records
+    stay pending until the server's `{t:'ia',seq}` ACK removes them.
+  - **POST path** — when no WS, POST records in order, awaiting each (the HTTP 2xx
+    *is* the ACK). A 404/410 (session gone) drops the record rather than retry
+    forever.
+- **Half-open recovery** (`_redeliverSweep`, every 2s): if the active WS session's
+  oldest record is unacked past `_reliableAckTimeoutMs` (4s), the socket is assumed
+  dead — `ws.close()` forces a fast reconnect; `onopen` (`_onWsReady`) resets
+  `sentAt = 0` and re-sends everything pending. Also re-drains background sessions
+  over POST, and fires on SSE-reconnect / `online`.
+- The connection indicator shows pending count/bytes (`_pendingBytes`).
+
+### Server
+
+- **`Session.shouldApplyInput(clientId, seq)`** — returns `true` exactly once per
+  `(clientId, seq)`: the first time a seq strictly greater than that client's
+  last-applied is seen. A replayed/lower seq returns `false`. Bounded MRU map
+  (`MAX_INPUT_DEDUP_CLIENTS = 256`).
+- **WS route** (`ws-routes.ts`) — parses optional `cid`/`seq` on `{t:'i'}`; applies
+  via `shouldApplyInput` (skips a duplicate, still ACKs with `{t:'ia',seq}` so the
+  client drops it). Untagged frames apply unconditionally (no behavior change).
+- **POST route** (`/api/sessions/:id/input`) — optional `seq`/`clientId` in
+  `SessionInputWithLimitSchema`; a deduped duplicate returns 200 without writing
+  (the 200 is the client's ACK). `curl`/legacy callers omit the fields and always
+  apply.
+
+## Known limitation
+
+Dedup state is in-memory on the server. A **server restart** between a write and
+the client's redelivery of that same seq could re-apply it (a rare duplicate).
+This is a deliberate trade-off: favor *never losing input* over a rare duplicate
+across the narrow restart window.
+
+## Tests
+
+- `test/reliable-input-dedup.test.ts` — `Session.shouldApplyInput` exactly-once
+  semantics (monotonic, per-client, gap-tolerant, eviction-safe).
+- `test/routes/session-routes.test.ts` — POST `/input` applies a tagged
+  `(clientId, seq)` once on redelivery; untagged input always applies.

+> 1. **UI is a master-detail TAB, not grouped floating subagent windows.** The user asked for the CC "working agents" view (left task picker, right agent stats). Built as a new docked panel `#ultracodeAgentsPanel` (clones `.subagents-panel` master-detail CSS) + `src/web/public/ultracode-panel.js` — NOT via `openSubagentWindow`/grouped windows.
+> 2. **STANDALONE — zero edits to `subagent-watcher.ts`.** w16-claudeman's commit `f6a30d7` already discovers the per-agent workflow *transcripts* (`watchWorkflowDirs`). The data the view needs (run/phase/per-agent tokens+toolCalls) lives in the *run-state* JSON, read by a brand-new `src/workflow-run-watcher.ts` (globs the disjoint `…/workflows/wf_*.json` tree). No shared files with w16.
+> 3. **No per-agent transcript streaming needed for v1.** The run-state JSON already carries `tokens`/`toolCalls`/`state`/`label`/`phase` per agent, so the whole view reads from `wf_<runId>.json` alone. (Phase 4 will optionally link a card to its already-tracked transcript via `agentId` — no watcher edits.)
+> 4. **Agent states are `start | progress | done`** (verified on disk) — NOT running/queued. `start`=queued (no agentId/tokens/toolCalls yet), `done` has `durationMs`/`resultPreview`.
+> 5. **The run JSON's `script` (15–660KB embedded JS), `scriptPath`, `result`, `logs` are STRIPPED in the watcher** before caching/broadcast (a 28-agent run drops 174KB → ~25KB; `promptPreview`/`resultPreview` truncated).
+> 6. **SSE/snapshot ship lightweight run SUMMARIES (no `agents[]`); the RIGHT pane fetches the full run** via `GET /api/workflows/:runId` on selection. (A 25-run snapshot is ~20KB vs ~900KB if it carried every agent.) The LEFT list shows ALL cached runs (LRU-bounded), not a recency window — a run browser must show past runs.
+>
+> _Original rev. 2 proposal (grouped floating windows, extending subagent-watcher) preserved below for context; superseded by the above._
+
+### What changed in rev. 2 (vs. the first draft)
+
+1. **No backend cross-watcher coupling.** The per-agent label/phase/agentType/state **join moves to the frontend at render time** — the run object already carries every agent's entry keyed by `agentId`. This deletes `subagent-watcher`'s backward dependency on `workflow-run-watcher` (`getAgentLabel()` + its TTL cache), removes the registration-vs-run-state **race** (labels always track the latest `workflow:run_updated`), and drops the per-agent `meta.json` read from the hot path.
+2. **`SubagentInfo` grows by 2 fields, not 4** (`isWorkflowAgent`, `workflowRunId`) — both derivable from the file path alone at registration, zero extra I/O. `agentType`/`label`/`phase`/`state` come from the run object on the frontend.
+3. **The `isInternalAgent` bypass covers BOTH drop sites** — `registerAgentFile` *and* the late re-resolution in `processEntry`. The first draft named only one.
+4. **De-duplicated.** Each trap (`journal.jsonl`, the `projects/*/*/workflows` depth, the gate-mismatch lesson, reuse-not-rebuild) is stated once in its owning section.
+
+### Code-reuse verified against the tree (2026-06-14)
+
+Confirmed present and shaped as assumed: `subagent-watcher.ts` — `watchSubagentDir`/`registerAgentFile`/`tailFile`/`processEntry`, `getRecentSubagents`, `isInternalAgent` (drops on `MIN_DESCRIPTION_LENGTH=5`), `STARTUP_MAX_FILE_AGE_MS=4h`, `MAX_TRACKED_AGENTS`, `knownSubagentDirs`/`dirWatchers`. `team-watcher.ts` — `configMtimes` mtime-skip + chokidar + `setInterval` poll. `server.ts` — `setupSubagentWatcherListeners`, `getLightState()` (`subagents: getRecentSubagents(15)`, `LIGHT_STATE_CACHE_TTL_MS=1000`), `isSubagentTrackingEnabled()` (`settings.subagentTrackingEnabled ?? true`). Frontend — `_SSE_HANDLER_MAP`, `this.subagents` Map, `handleInit`/`cleanupAllFloatingWindows`, `renderSubagentPanel`/`_renderSubagentPanelImmediate`, `getTeammateBadgeHtml`, `openSubagentWindow` + `.subagent-window-parent` sub-header.
+
+## 1. The enabling fact: on-disk artifacts
+
+The Workflow tool (what `ultracode` drives) persists each workflow agent as a transcript under the **same `subagents/` directory Codeman already watches**, one level deeper. Empirically verified against a real run (`wf_a8e09f2c-550`); **re-confirm the shape against a fresh run at implementation time** (§8 mandates a live e2e pass anyway):
+
+```
+~/.claude/projects/<projHash>/<sessionUuid>/
+  ├─ subagents/
+  │    ├─ agent-XX.jsonl                    ← regular Task subagent (tracked today)
+  │    └─ workflows/wf_<runId>/
+  │         ├─ agent-YY.jsonl               ← WORKFLOW agent — IDENTICAL line format
+  │         ├─ agent-YY.meta.json           ← {"agentType":"workflow-subagent"} (optional enrichment)
+  │         └─ journal.jsonl                ← run journal {type:"started",...} — MUST be skipped
+  └─ workflows/wf_<runId>.json              ← run state: runId, workflowName, summary, status,
+                                               phases[], workflowProgress[], totals (DIFFERENT tree)
+```
+
+The per-agent `.jsonl` line shape is identical to a regular subagent transcript:
+
+```jsonc
+{ "parentUuid": null, "isSidechain": true, "agentId": "ac6a1d27012a64e38",
+  "type": "user" | "assistant", "message": { "role": "...", "content": "..." }, ... }
+```
+
+Because the line shape is identical, the entire existing parse→event→render pipeline works unchanged once discovery reaches those files. The only new data is the **run-level metadata** in `workflows/wf_<runId>.json` (name, summary, phases, and `workflowProgress[]` — the per-agent labels/state/tools), which supplies the group header and per-agent labels.
+
+**Can show:** per-agent live transcript (tool calls, messages, results); per-agent status (active/idle/completed via the existing mtime/PID/pgrep liveness); per-agent model + running token totals (from each agent's JSONL `message.usage`, exactly as today); the run's `workflowName`/`summary`/`phases[]`; per-agent `label`/`phaseTitle`/`state`/`lastToolName` (from `workflowProgress[]`); grouping under `wf_<runId>`.
+
+**Cannot show:** anything absent from the artifacts — a live phase cursor beyond `workflowProgress[].state`; an authoritative **budget/cost ceiling** (only consumed totals exist — `usage` + run-state `totalTokens`, no remaining-budget field); runs older than `STARTUP_MAX_FILE_AGE_MS` (4h) after a server restart (live monitoring only).
+
+## 2. Architecture
+
+**Decision: EXTEND `subagent-watcher.ts` for per-agent discovery/streaming; ADD a thin `workflow-run-watcher.ts` (modeled on `team-watcher.ts`) for the group-header metadata ONLY. The agent→run-metadata join happens on the FRONTEND, so the two watchers stay decoupled.**
+
+- The per-agent JSONL is identical in shape, so re-running it through `registerAgentFile()` → `tailFile()` → `processEntry()` and the existing `subagent:*` events is free and reconnect-safe (those agents land in `agentInfo`, replayed by `getRecentSubagents(15)`). A parallel per-agent watcher would duplicate the liveness/token/tool-call/SSE machinery for zero benefit.
+- Run metadata lives in a *different* file under a *different* tree (`workflows/wf_<runId>.json`, sibling to `subagents/`). A small `WorkflowRunWatcher` watching `projects/*/*/workflows/wf_*.json` (mtime-skip, like `team-watcher`'s `configMtimes`) is the clean home; folding it into `subagent-watcher` would entangle two unrelated watch roots and put a JSON re-read in the hot per-line path.
+- **The two watchers never call each other.** The frontend receives both streams and joins agent→label by `agentId` at render time (the run object carries every agent's entry). This removes the timing coupling entirely.

+```
+
+## 3. Backend changes (ordered, file-by-file)
+
+### 3a. `src/subagent-watcher.ts` — nested discovery + 2 tag fields
+
+**(1) Extend `SubagentInfo` with exactly two optional fields** (optional → regular subagents and the wire shape are unaffected):
+
+```ts
+isWorkflowAgent?: boolean;   // true when discovered under subagents/workflows/<wf_runId>/
+workflowRunId?: string;      // e.g. "wf_23dbeab2-152" (parent dir name)
+```
+
+Both are derived from the **file path alone** at registration — no extra reads. They ride existing `subagent:discovered|updated|completed` payloads (no new per-agent event). Do **not** add `agentType`/`label`/`phase`/`workflowName` here — those come from the run object on the frontend (§4c).
+
+**(2) Constant.** `const WORKFLOWS_SUBDIR = 'workflows';` near the existing dir constants.
+
+**(3) `watchSubagentDir()` — descend into `workflows/<wf_runId>/`.** After the existing direct-child registration loop:
+
+```ts
+// Workflow agents live one level deeper: subagents/workflows/<wf_runId>/agent-*.jsonl
+const wfRoot = join(dir, WORKFLOWS_SUBDIR);
+try {
+  for (const runId of await readdir(wfRoot)) {
+    if (!runId.startsWith('wf_')) continue;
+    await this.watchWorkflowRunDir(join(wfRoot, runId), projectHash, sessionId, runId);
+  }
+} catch { /* no workflows subdir — normal for most sessions */ }
+```
+
+The existing `fs.watch(dir, …)` on `subagents/` is **non-recursive on Linux** and won't fire for writes inside `workflows/<runId>/`, so each run dir needs its own watcher.
+
+**(4) New private `watchWorkflowRunDir(runDir, projectHash, sessionId, runId)`** — clone `watchSubagentDir`'s structure, but:
+- Register only files matching `^agent-.*\.jsonl$`, **explicitly skipping `journal.jsonl`** (it ends in `.jsonl` but is `{type:'started',…}`, not a transcript — registering it would create a phantom agent).
+- Call `registerAgentFile(filePath, projectHash, sessionId, isInitialScan, runId)` so the agent is tagged.
+- Install one `watch(runDir, …)` per run dir; on `error` and `stop()`, reuse the existing teardown (close + delete from `dirWatchers`/`knownSubagentDirs`/`dirWatcherErrorHandlers`).
+- Guard re-registration **per run dir** in `knownSubagentDirs`, **not** `wfRoot` — the 5s full scan must still re-`readdir(wfRoot)` to pick up *new* `wf_<runId>` dirs created mid-session.
+
+**(5) `registerAgentFile()` — accept + apply `runId`.** Add a trailing optional `runId?: string`. When set, the whole change is:
+
+```ts
+if (runId) { info.isWorkflowAgent = true; info.workflowRunId = runId; }
+```
+
+No `meta.json` read, no run-state lookup, no description override. `agentId`s are globally unique `a<16hex>` (verified: 0 collisions across a 370-agent corpus), so keep the flat `agentInfo` map keyed by `agentId` — do **not** switch to a composite key. Add a one-line dev-assert log if `agentInfo.has(agentId)` with a *different* `workflowRunId`, so a future collision is observable.
+
+**(6) `isInternalAgent` bypass — BOTH drop sites.** Workflow agents have no Task-tool spawn record, so `_resolveDescription` yields only the first-user-message fallback (often a long phase prompt) or empty → `isInternalAgent` (`length < MIN_DESCRIPTION_LENGTH`) would wrongly drop them. They are real by construction (the `subagents/workflows/wf_*/` path is the discriminator). Gate the drop on `!info.isWorkflowAgent` at **both** places:
+- `registerAgentFile` initial check (`isInternalAgent(description)`),
+- `processEntry`'s late re-resolution (the second `isInternalAgent` call).
+
+**(7) `stop()` teardown.** Per-run watchers live in `dirWatchers`, so the existing close-all loop covers them — verify no separate map was introduced (24h runs spawn many `wf_<runId>` dirs → FSWatcher leak risk).
+
+### 3b. NEW `src/workflow-run-watcher.ts` (singleton, EventEmitter — model on `team-watcher.ts`)
+
+- **Watch root:** `~/.claude/projects/<projHash>/<sessionUuid>/workflows/wf_*.json` — **two** levels under `projects` (verified: `projects/*/workflows` is empty; must be `projects/*/*/workflows/`). chokidar `depth:3` + a poll fallback, mirroring `team-watcher`'s dual discovery + interval.
+- **mtime-skip:** `runMtimes: Map<absPath, number>` (mirror `team-watcher.configMtimes`).
+- **Parse:** read `wf_<runId>.json`, take the **top-level structured keys** (`runId`, `workflowName`, `summary`, `status`, `phases:[{title,detail}]`, `agentCount`, `defaultModel`, `durationMs`, `totalTokens`, `totalToolCalls`, `workflowProgress[]`). **Do NOT parse the embedded `script` string** — name/phases/summary are already top-level; the script's `export const meta` is redundant and costly. Derive `sessionUuid` from the dir name, `projectHash` from the dir above; expose `getProjectHash(workingDir)` for Codeman-session correlation.
+- **`workflowProgress[] → agents[]`:** filter `type === 'workflow_agent'`, map each to a `WorkflowAgentEntry` (§3c) keyed by `agentId`. **This array is the join source the frontend uses** — no backend `getAgentLabel()` API, no TTL cache, no import from `subagent-watcher`.
+- **Emit** `workflow:run_discovered|updated|removed` carrying `WorkflowRunInfo`; removal by set-diff (mirror `team-watcher`).
+- **Lifecycle:** `start()`/`stop()` with `CleanupManager` teardown of chokidar + interval + caches; `LRUMap`-bounded run cache (24h memory rule).
+
+### 3c. `src/types/` — workflow run types
+
+```ts
+export interface WorkflowAgentEntry {   // one workflowProgress[type==='workflow_agent']
+  agentId: string; label: string; phaseIndex?: number; phaseTitle?: string;
+  agentType?: string; model?: string; state?: string;       // 'done'|'running'|'queued'|...
+  lastToolName?: string; lastToolSummary?: string; tokens?: number; toolCalls?: number;
+}
+export interface WorkflowRunInfo {
+  runId: string; sessionUuid: string; projectHash: string;
+  workflowName?: string; summary?: string; status?: string;  // 'running'|'completed'|...
+  phases: Array<{ title: string; detail?: string }>;
+  agentCount?: number; defaultModel?: string;
+  agents: WorkflowAgentEntry[];          // workflowProgress filtered to workflow_agent, keyed by agentId
+  startedAt?: number; durationMs?: number; totalTokens?: number; totalToolCalls?: number;
+}
+```
+
+The two `SubagentInfo` workflow fields stay inline in `subagent-watcher.ts` (matching the existing convention).
+
+### 3d. `src/web/sse-events.ts` — register run events
+
+Add `workflow:run_discovered`, `workflow:run_updated`, `workflow:run_removed` after the `subagent:*` block and to the `SseEvent` union. **No new per-agent event** — workflow agents reuse `subagent:*`.
+
+### 3e. `src/web/server.ts` — bridge, snapshot, gating
+
+- **`setupWorkflowRunWatcherListeners()`** (beside `setupSubagentWatcherListeners`): map the three run events → `this.broadcast(...)`. Add `cleanupWorkflowRunWatcherListeners()` (store handler refs).
+- **Start/stop:** call `workflowRunWatcher.start()`/`.stop()` beside `subagentWatcher`, **gated on the same enable condition** (§3f).
+- **`getLightState()`:** add `workflowRuns: workflowRunWatcher.getRecentRuns(15)` beside `subagents: subagentWatcher.getRecentSubagents(15)` so headers replay on reconnect (agents already replay via `subagents`). Keep the `LIGHT_STATE_CACHE_TTL_MS` memoization.
+- **Gating read:** add `isWorkflowAgentTrackingEnabled()` mirroring `isSubagentTrackingEnabled()` (boot-time `dataPath('settings.json')` read). Gate `workflowRunWatcher.start()` **and** the subagent-watcher `workflows/` descent (§3a-3) on `showUltracodeAgents` so non-opted-in users never register historical workflow agents.
+
+### 3f. `src/web/schemas.ts` — settings key
+
+Add `showUltracodeAgents: z.boolean().optional()` to the `.strict()` settings update schema near `showPlanUsageLimits` (required — `.strict()` 400s the whole PUT on an unknown key).
+
+### 3g. `src/web/routes/system-routes.ts` — poll API
+
+- `GET /api/subagents` and `GET /api/sessions/:id/subagents` include workflow agents once registered — **no change** (they carry `isWorkflowAgent`/`workflowRunId`; a consumer joins to `/api/workflows/:runId` for labels).
+- Add `GET /api/workflows` → `workflowRunWatcher.getRecentRuns()` and `GET /api/workflows/:runId` (uniform `ApiResponse` contract; headers are also in `getLightState`).
+- `GET /api/subagents/:agentId/transcript` works for workflow agents (they're in `agentInfo`) — no new route.
+
+## 4. Frontend changes (file-by-file)
+
+### 4a. `src/web/public/constants.js`
+- Add the three SSE strings to `SSE_EVENTS`, matching §3d exactly (`WORKFLOW_RUN_DISCOVERED: 'workflow:run_discovered'`, etc.).
+- Reuse `ZINDEX_SUBAGENT_BASE=1000` for the agent windows (they ARE subagent windows). The group **header/cluster** is in-flow panel DOM, not a floating window — no new z-index (1100 is plan-subagent).
+
+### 4b. `src/web/public/app.js`
+- Constructor: `this.workflowRuns = new Map();  // runId -> WorkflowRunInfo` beside `this.subagents`.
+- `_SSE_HANDLER_MAP`: add three rows → `_onWorkflowRunDiscovered/Updated/Removed` (must exist before `connectSSE` builds the wrappers).
+- `handleInit`: after seeding `data.subagents`, seed `this.workflowRuns` from `data.workflowRuns` (clear-then-set). **Clear `this.workflowRuns` everywhere the subagent Maps are cleared** (incl. `cleanupAllFloatingWindows`) — 24h leak guard.
+
+### 4c. `src/web/public/panels-ui.js` — the join lives here
+- `_onWorkflowRunDiscovered/Updated(data)` → `this.workflowRuns.set(data.runId, data)` + debounced re-render; `_onWorkflowRunRemoved` → delete + re-render.
+- **No change to `_onSubagentDiscovered/Updated`** — they already store the whole payload, so the 2 new fields ride along.
+- `renderSubagentPanel`/`_renderSubagentPanelImmediate`: when `showUltracodeAgents` is on, **partition `this.subagents` into flat (no `workflowRunId`) vs grouped-by-`workflowRunId`**. Flat agents render exactly as today. For each group: build the header from `this.workflowRuns.get(runId)` (`workflowName` + phase/status chip from `phases[]`), then render that run's agents reusing the existing per-agent row markup. **Per-agent label/phase/agentType come from the JOIN** — build `Map(agentId → entry)` from `this.workflowRuns.get(runId).agents` and look each agent up by `agent.agentId`; render the small chip via the `getTeammateBadgeHtml` pattern. (If the run object hasn't arrived yet, fall back to the agent's own `description` — the run `:updated` event will fill it in on the next render.)
+- `findParentSessionForSubagent` is unchanged — workflow agent `sessionId === session.claudeSessionId`. **Do not conflate `workflowRunId` with `sessionId`.**
+
+### 4d. `src/web/public/subagent-windows.js`
+**Decision: REUSE `.subagent-window` per agent + a group sub-header — do NOT build a cluster class.** A cluster path duplicates Map/z-index/drag/cleanup/persistence for no functional gain; reuse keeps connection lines, minimize-to-tab, and `localStorage` persistence. In `openSubagentWindow`, where the optional `.subagent-window-parent` sub-header is built: when `agent.workflowRunId` is set, inject a `.subagent-workflow-header` showing `this.workflowRuns.get(runId)?.workflowName` + the joined agent's `label`/phase (look up by `agentId`), mirroring the `from <session>` sub-header. Respect the existing skip guards (teammate-terminal windows, minimized/`_lazyTerminal`).
+
+**Do NOT auto-open windows** for workflow agents — a multi-phase run can spawn many, against the 50-window/60fps budget + `MAX_TRACKED_AGENTS=500`. They render collapsed in the grouped panel; the user expands via the existing panel buttons.
+
+### 4e. `src/web/public/settings-ui.js` + `index.html`
+- `index.html` Panels block: add a `settings-item` checkbox `id="appSettingsShowUltracodeAgents"` ("Show ULTRACODE / Workflow Agents").
+- `openAppSettings`: load `settings.showUltracodeAgents` with `false` fallback (mirror `showPlanUsageLimits`).
+- `saveAppSettings`: collect `showUltracodeAgents` into the fresh settings literal (uncollected keys reset to default every save).
+- Live-apply on toggle: re-run `renderSubagentPanel()` (show/hide group sections) — a panel re-render, not a CSS-class strip.
+- **SYNCED, not per-device:** do NOT add `showUltracodeAgents` to `displayKeys` and do NOT strip it in the per-device block. A synced value gives the server-side gate (`isWorkflowAgentTrackingEnabled`, §3e) one canonical truth to decide whether to run the watcher; a per-device value can't gate a process-wide watcher. (Contrast `showResponseViewer`, pure client display.)
+- `styles.css` + `mobile.css`: add `.subagent-workflow-header` and `.subagent-group-badge` next to `.subagent-window-parent`; mirror device overrides in `mobile.css`.
+
+## 5. Settings / opt-in wiring
+
+- **Key:** `showUltracodeAgents` (boolean, **default OFF**). Fallback `false` in `openAppSettings`; "absent ⇒ off" in `isWorkflowAgentTrackingEnabled()`. Schema `z.boolean().optional()` in the `.strict()` update schema, kept OUT of `displayKeys` (synced).
+- **Runtime gating:** `workflowRunWatcher.start()` and the subagent-watcher `workflows/` descent run only when the boot-time `settings.json` read reports `showUltracodeAgents === true` (mirroring `isSubagentTrackingEnabled`). The frontend additionally gates display. Toggling at runtime gates **display** immediately (panel re-render); the **watcher branch** picks up on next boot — matches existing `subagentTrackingEnabled` semantics. (Optional polish: restart just the workflow watcher on toggle for instant on/off.)
+
+## 6. SSE events
+
+**Reused (no change):** `subagent:discovered|updated|tool_call|tool_result|progress|message|completed`. Workflow agents flow through these; payloads now carry the optional `isWorkflowAgent`/`workflowRunId` fields on `SubagentInfo`. SSE payloads aren't schema-gated (typed only at `broadcast()` call sites), so the new fields propagate with zero friction.
+
+**New (3 events, run-level metadata):**
+
+| Event (backend const / frontend key) | Payload |
+|---|---|
+| `workflow:run_discovered` / `WORKFLOW_RUN_DISCOVERED` | `WorkflowRunInfo` |
+| `workflow:run_updated` / `WORKFLOW_RUN_UPDATED` | `WorkflowRunInfo` |
+| `workflow:run_removed` / `WORKFLOW_RUN_REMOVED` | `{ runId: string }` |
+
+Sync requirement (CLAUDE.md): each must appear in **both** `sse-events.ts` (§3d) and `constants.js` `SSE_EVENTS` (§4a), be emitted via `broadcast()` in `setupWorkflowRunWatcherListeners()` (§3e), and have a dispatch-table row + `_on*` handler (§4b/§4c).
+
+## 7. Edge cases & cleanup
+
+- **`journal.jsonl` phantom-agent trap** — owned by §3a-4: run-dir registration requires the `agent-` prefix and excludes `journal.jsonl`.
+- **`isInternalAgent` over-filtering** — owned by §3a-6: bypass at BOTH drop sites; titled from the frontend join (or the description fallback).
+- **No workflow agents in the flat list** — `renderSubagentPanel` partitions on `agent.workflowRunId` (§4c). When the toggle is OFF, the descent never ran, so they aren't in `this.subagents` at all.
+- **Completion/idle** — keep the existing per-agent mtime/PID/pgrep liveness as the per-card source of truth. Optionally render a group-level "workflow done" badge from run-state `status==='completed'`.
+- **Limits** — `MAX_TRACKED_AGENTS=500` LRU-evicts workflow agents in the same flat map; no auto-open (50-window budget); the 4h `STARTUP_MAX_FILE_AGE_MS` skip means a run completed >4h ago won't reload after restart (acceptable — live monitoring).
+- **Reconnect/replay** — agents via `getRecentSubagents(15)`; headers via `workflowRuns: getRecentRuns(15)` in `getLightState`. `handleInit` clears `this.workflowRuns` alongside the subagent Maps.
+- **Watcher teardown** — every per-run `fs.watch` and the chokidar watcher closes in `stop()` and on `error`; `CleanupManager` for the new watcher (24h runs create many run dirs).
+- **CLAUDE.md discipline** — read-only `~/.claude/...` artifacts; no new `~/.codeman/...` paths, no env-var prefixes touched. Claude-mode-only by nature (external CLIs don't write workflow transcripts).
+
+## 8. Testing & verification
+
+- **Unit (pure):**
+  - `test/workflow-run-watcher.test.ts`: feed a scrubbed fixture `wf_<runId>.json` → assert `WorkflowRunInfo` extraction (name/summary/phases, `workflowProgress`→`agents[]` keyed by `agentId`), mtime-skip, removal-by-set-diff.
+  - Extend `subagent-watcher` coverage: temp `subagents/workflows/wf_X/agent-Y.jsonl` + a stray `journal.jsonl` → assert `agent-Y` registered with `isWorkflowAgent`/`workflowRunId` and `journal.jsonl` NOT registered; assert a short-description workflow agent is NOT dropped at **either** `isInternalAgent` site.
+- **Route/inject (`app.inject`):** `GET /api/workflows` + `:runId` return the `ApiResponse` envelope; `GET /api/subagents` includes a tagged agent.
+- **Frontend (vm-sandbox, like `test/run-mode-ui.test.ts`):** dispatch `subagent:discovered` with `workflowRunId` + `workflow:run_discovered` → assert `renderSubagentPanel` produces a group section under the workflow name with the agent inside it (label sourced from the **join**, not flat); assert order-independence (agent before run, and run before agent both resolve); assert OFF hides the section.
+- **REQUIRED real end-to-end** (the always-end-to-end-test rule — the plan-usage chip shipped *dead* from a gate mismatch): on dev/beta with `showUltracodeAgents` ON, **drive a real ultracode/workflow run**, then (1) `curl …/api/workflows | jq` shows the live run with `agents[]`; (2) `curl …/api/subagents | jq '.data[]|select(.isWorkflowAgent)'` shows tagged agents; (3) watch `/api/events` for `workflow:run_discovered` + `subagent:discovered` with the workflow fields; (4) Playwright (`waitUntil:'domcontentloaded'`, wait 3–4s) asserts the grouped DOM cluster renders with the workflow-name header and live status. Verify path gates against `GET /api/sessions` `workingDir`. **Test against a LIVE run** — all at-rest runs are `completed`/`done`; `running`/`queued` states only exist mid-run.
+
+## 9. Phased rollout
+
+| Phase | Scope | Done-check | Size |
+|---|---|---|---|
+| **P1 — Backend discovery + tagging (gated, no UI)** | §3a (nested descent, `journal.jsonl` skip, 2 `SubagentInfo` fields, `isInternalAgent` bypass ×2) + §3f schema key + §3e gate read. No run watcher yet. | With `showUltracodeAgents` forced on, `curl /api/subagents \| jq '.data[]\|select(.isWorkflowAgent)'` lists real workflow agents during a live run; flat subagents unchanged; `tsc --noEmit` + targeted watcher test green. | S–M |
+| **P2 — Run-state metadata + SSE** | §3b (`workflow-run-watcher.ts`) + §3c types + §3d/§3e (SSE, bridge, `getLightState` replay) + §3g routes. | `curl /api/workflows \| jq` returns runs with `agents[]`/`phases`; SSE emits `workflow:run_discovered`; reconnect snapshot carries `workflowRuns`. | M |
+| **P3 — Frontend grouped UI** | §4a–§4d (constants, app.js state/dispatch/init, panels-ui grouped render + **agent→label join**, subagent-windows group sub-header). Reuse `.subagent-window`; no auto-open. | Playwright: live run renders a group section under the workflow name with per-agent rows + live status + joined labels; flat subagents stay flat; expand opens a window with the workflow sub-header. | M |
+| **P4 — Settings toggle + polish + docs** | §4e (checkbox, settings-ui load/save/live-apply, SYNCED), styles/mobile, phase chips, CLAUDE.md "Key Patterns" entry + this doc's status → SHIPPED. | Toggling the checkbox shows/hides the cluster live (no reload for display); OFF by default on a fresh install; CI green. | S |
+
+Each phase is independently shippable: P1 is invisible (gated, no UI), P2 adds an API with no UI dependency, P3 lights up the UI for flag-enablers, P4 exposes the toggle and finalizes defaults/docs.
+
+## 10. Effort & risk
+
+**Size:** P1 = S–M, P2 = M, P3 = M, P4 = S. Total ≈ **M** (one focused engineer, ~2–4 days incl. the real end-to-end run — down from the first draft's M-L now that the backend join/coupling is gone).
+
+**Top 3 risks:**
+
+1. **Non-recursive watch on Linux misses live writes.** `fs.watch` is non-recursive and `{recursive:true}` is unreliable on Linux → per-`wf_<runId>` watchers (§3a-4) are correct, but the 5s full scan must re-`readdir(wfRoot)` to catch *new* run dirs mid-session, and each watcher must be torn down to avoid FSWatcher leaks in 24h runs. Mitigation: explicit per-run-dir registration + verified `dirWatchers` teardown; chokidar (with `CleanupManager`) only in the new run watcher, where `team-watcher` already proves the pattern.
+2. **Discovery cost / over-registration.** A user with hundreds of historical workflow agents could flood `agentInfo` on boot. Mitigation: the 4h `STARTUP_MAX_FILE_AGE_MS` skip drops old files on the initial scan, the descent only runs when the toggle is on, and `MAX_TRACKED_AGENTS=500` LRU-evicts. Verify boot scan time doesn't regress with the corpus present.
+3. **Shipping-dead-on-a-gate** (the repo's recurring failure mode — the plan-usage chip shipped dead because injection was gated on `CASES_DIR` while real sessions ran elsewhere). Same trap here if the path/mode gate is wrong (e.g. `projects/*/workflows` instead of `projects/*/*/workflows`, or correlation via the wrong session key). Mitigation: the **mandatory live ultracode end-to-end run** in §8 against a real session's `workingDir`, observing the real SSE event + real DOM cluster — not the at-rest corpus, not unit tests alone.

+ * pane running `ssh host` into a durable remote tmux server, a local tmux pane
+ * runs `docker exec -it` into a durable IN-CONTAINER tmux server. The container is
+ * scoped to the CASE (`codeman-case-<name>`), so multiple sessions can `docker
+ * exec` into the same long-lived container.
+ *
+ * This module mirrors `remote-hosts.ts`:
+ *  - JSON storage for hosts (`docker-hosts.json`) and cases (`docker-cases.json`)
+ *  - `toSessionDocker()` (mirror of `toSessionRemote`)
+ *  - `buildDockerBaseArgs()` / `buildDockerCreateArgs()` (mirror of `buildSshConnectionArgs`)
+ *  - `checkDockerAvailable()` / `checkDockerTmuxAvailable()` (mirror of `checkRemoteTmuxAvailable`)
+ *
+ * The launch/kill command orchestration (`buildDockerLaunchCommand`,
+ * `buildDockerKillCommand`, `dockerTmuxSessionName`) lives in `tmux-manager.ts`,
+ * mirroring where `buildRemoteLaunchCommand` lives.

+ * grouped, ranked, and capped results. It performs NO I/O — the route wrapper

+ * v1 scope (do not expand here): three sources — sessions/cases, run-summary
+ * events, file paths. Terminal-buffer scanning and any persisted index are

+ * Ranking: results are grouped by source type in the fixed order
+ * sessions → events → files. Within each group, exact (case-insensitive)
+ * name/path matches come first, then recency (newest timestamp first) as the
+ * tiebreak. There is no relevance-scoring pass in v1.
+ *
+ * Safety: file results only ever expose a workspace-relative path — server-
+ * private absolute paths are never placed in a result. Per-group and total caps
+ * bound the output so a broad query cannot return an unbounded payload.

  * This means compositionstart fires even for English text, and compositionend

- * We use InputEvent.inputType to distinguish:

- * - `insertText`: final committed text (confirmed word, punctuation, space)
+ * During composition, all input events are ignored — only compositionend

- * During composition, `insertText` events are flushed immediately (punctuation,

+ * ## iOS dictation challenge (WebKit Bug 261764)
+ *
+ * iOS/iPadOS voice dictation does NOT fire composition events. Text arrives
+ * as bare input events with isComposing === false. Dictation refinement is
+ * a delete→reinsert cycle (deleteContentBackward + insertReplacementText),
+ * all within a few ms. Flushing on every input event would send irrevocable

+ * Solution: outside composition, flush is DEBOUNCED (200ms). The entire

+ * with a connector line to the originating session tab.
+ *
+ * This is the "floating thing" companion to the docked master-detail panel in
+ * `ultracode-panel.js` (the dock panel stays — these windows are ADDITIONAL).
+ * When the `ultracodeFloatingWindows` setting is on (a DEDICATED toggle, separate
+ * from the dock panel's `showUltracodeAgents` — see `_ultracodeFloatingEnabled`),
+ * a small floating window pops up
+ * for each ACTIVE ultracode/Workflow run (status not completed/killed/failed),
+ * mirroring the live agent grid, and is connected by a glowing line to the
+ * Codeman tab whose `claudeSessionId` matches the run's `sessionUuid` — the same
+ * line idiom subagent windows use. The window auto-closes a few seconds after
+ * its run finishes; an explicitly-closed run is remembered and never re-pops.
+ *
+ * Reuses, rather than duplicates:
+ *  - `makeWindowDraggable` + the shared `#connectionLines` SVG (subagent-windows.js)
+ *  - `_workflowAgentCardHtml`, `_fmtNum`, `_workflowStatusClass`, `_fetchWorkflowRunDetail`,
+ *    and the `workflowRuns` / `workflowRunDetails` maps (ultracode-panel.js)
+ *
+ * The connector-line draw is appended to the shared SVG from inside
+ * `_updateConnectionLinesImmediate` (subagent-windows.js calls
+ * `_appendUltracodeConnectionLines` at the end of its render pass), so both the
+ * subagent and ultracode lines live in one batched read→write reflow pass.
