feat(tunnel,ui): purple tunnel button + opt-in unauthenticated tunnel with warning (v1.1.9)

- Daylight Blue: Cloudflare Tunnel welcome button is now purple (was orange),
  keeping Claude blue / Tunnel purple / OpenCode green distinct.
- Allow enabling the Cloudflare tunnel with no CODEMAN_PASSWORD via the UI: the
  toggle now pops a security confirm dialog and, on confirm, sends an explicit
  per-request acknowledgeUnauthTunnel:true (new action field, never persisted).
  Server logs a loud warning whenever a passwordless public tunnel starts.
  curl/API/CLI stay refused unless password/env/flag — no accidental exposure.

Tests: extend test/routes/system-routes-tunnel-guard.test.ts (ack allows + not
persisted; ack:false still refuses). Verified e2e on an isolated instance
(purple button, confirm dialog, retry carries the flag, no real tunnel opened).

+
+Quick pointers:
+
+- Type check: `tsc --noEmit` · Lint: `npm run lint` · Format: `npm run format:check`
+- Targeted tests only: `npm test -- test/<file>.test.ts` (bare `npm test` is unsafe in managed sessions)

+## 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.
+
+## 1.1.1
+
+### Patch Changes
+
+- Six reviewed contributor PRs (all adversarially reviewed and fixed before merge):
+  - **Markdown sanitizer hardened against mutation-XSS (#126).** The denylist `_sanitizeHtml` is replaced with vendored DOMPurify 3.4.8 (authentic, byte-matched to the official dist) wired via a new `sanitize-html.js` allowlist, with a fail-closed escape fallback. The curated allowlist is genuinely enforced (no `USE_PROFILES` override) so non-markdown tags and svg/math/style/script/event-handler/`javascript:` vectors are stripped while legitimate markdown survives.
+  - **Hook-event secret now required unconditionally (#127).** The `/api/hook-event` + `/api/status-telemetry` localhost bypass requires the per-instance hook secret whether or not a managed tunnel is running, closing the own-loopback-reverse-proxy gap. A self-heal refreshes pre-secret hook configs in existing cases on spawn so password-protected installs don't silently 401 their hooks. No-password loopback installs are unaffected.
+  - **`codeman doctor` dependency checker (#125).** New `doctor`/`check-deps` command probes Node, the agent CLIs, tmux, and document converters per environment (linux/darwin/win32/wsl), with grouped or `--json` output and a non-zero exit when a required tool is missing. Requires Node 22+, reports `pdftoppm` (used for PDF/Office thumbnails), and validates `--category`.
+  - **macOS Option / physical-key session shortcuts (#129).** Tab switching matches physical key codes (`e.code`) so Option+1–9 works on macOS layouts that remap Option, plus Option/Alt+`[`/`]` for previous/next session — without leaking escape sequences into the focused terminal.
+  - **Desktop session tabs auto-wrap to a second row on overflow (#128)** instead of horizontal scrolling (off when the manual two-row layout is pinned; mobile/tablet unchanged), re-evaluated on window resize.
+  - **CJK input textarea hidden on the welcome screen (#123)** so it no longer floats over the welcome overlay, and re-shown on session entry; vertical centering fixed.
+
+## 1.1.0
+
+### Minor Changes
+
+- **Plan Usage Limits chip (new).** A header chip now shows your live Claude plan usage — the 5-hour and weekly windows as a percentage — parsed from Claude Code's statusLine telemetry (CLI v2.1.80+). It's opt-in via **App Settings → Display → "Plan Usage Limits"** (default OFF). The toggle is **per-device**: turn it on at your desk without it appearing on your phone. Telemetry collection is decoupled from display, so one device's preference never affects another's, and the last-known value replays instantly on reconnect. Distinct from auto-resume (which reacts to the limit _message_) — this proactively shows the live %.
+
+  **Attachments.** New attachment history drawer to browse files referenced by a session (COD-39), plus document previews and thumbnails on attachment cards (COD-38). The header **Attachments button is now opt-in** (default OFF) via **App Settings → Display → "Attachments Button"**, per-device like the Response Viewer button.
+
+  **Settings & models.** Added Opus 4.6 options to the Claude Model picker. Removed the legacy Token Count / Show Cost header toggles and moved Plan Usage Limits to the top of the Display settings. Slimmed the Skin picker control to match its row.
+
+  **Mobile & header polish.** Restored the response-viewer (eye) button on phones; kept the phone header minimal (settings gear + lifecycle log stay in the toolbar). Added two regression guards so header controls can't silently leak onto the mobile header again — a CI-runnable static policy check plus a real-browser E2E test.
+
+## 1.0.0
+
+### Major Changes
+
+- # Codeman 1.0.0 🎉
+
+  The first stable release of Codeman — and it comes with a fresh new look.
+
+  **New: theme skins.** Codeman now ships a built-in skin switcher (App Settings → Display → Appearance):
+  - **OG Codeman** — the original look, preserved exactly.
+  - **Daylight Green** — a fresh emerald-on-slate theme.
+  - **Daylight Blue** — bright sky-blue on lifted slate (the new default).
+
+  Skins apply instantly, persist per device (with a pre-paint script so there's no flash on load), and re-theme any open terminals live. The system is built on `html[data-skin]` design tokens and self-hosted Manrope (UI) + JetBrains Mono (terminal) fonts — no external CDN, CSP-safe.
+
+  **1.0.0 milestone.** This marks the start of the stable 1.x line: the CLI, documented environment variables, and the `{ success, data }` HTTP/SSE API envelope follow semantic versioning (see `docs/versioning-policy.md`).
+
+  **Thank you to everyone who helped build Codeman.** This release is dedicated to all of our contributors for their work on the project: Ark0N, Aamer Akhter (@aakhter), Tenggan Zhang (@TeigenZhang), zhouyuan / @sunnyzhouy, jaypark, Marco Migozzi, Skúli Arnlaugsson, Aaron Fields, Loïc Sculier, and Noah Waldner (@noahwaldner). 💙
+
+## 0.9.14
+
+### Patch Changes
+
+- Security hardening for the tunnel exposure path, Codex terminal rendering fixes, and a mobile modal fix.
+
+  **Security (PR #115, COD-54/COD-55):**
+  - `/api/hook-event` localhost bypass is now gated while the managed Cloudflare tunnel is running: tunneled traffic arrives with a loopback source IP, so the bypass additionally requires a per-instance shared secret (`X-Codeman-Hook-Secret`, 256-bit, `~/.codeman/hook-secret`, mode 0600). Locally generated hook commands read the secret file at execution time via `$CODEMAN_HOOK_SECRET_FILE` (exported into every managed session's environment), so the value never lands on command lines or in case configs, and running sessions pick up a new secret without respawn. Failed presentations rate-limit in a dedicated per-IP bucket so misfiring legacy hooks can never lock out the Basic-Auth login path. With no tunnel running, behavior is unchanged.
+  - Enabling the Cloudflare tunnel now **refuses with 403** when no `CODEMAN_PASSWORD` is set (a public tunnel URL with no auth is effectively public RCE), unless `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` explicitly acknowledges the exposure. The settings UI surfaces the refusal as an error toast and reverts the toggle.
+
+  **Codex rendering (PRs #116, #117):**
+  - Alt-screen toggles (`?47/?1047/?1049`), scrollback-erase (`CSI 3 J`), and mouse-tracking enables (`?1000`–`?1007`) are stripped from the Codex byte stream (live + replay), so conversation history survives tab switches and the scroll wheel scrolls the viewport instead of being hijacked. Sequences split across PTY chunk boundaries are reassembled via a small carry before stripping, so a split `?1049h` can no longer trap xterm in the scrollback-less alt buffer.
+  - Smaller 32KB first-frame write budget for Codex sessions keeps dense synchronized redraws from stalling the renderer; a 1.5s grace window after a manual scroll-up suppresses sticky-scroll so high-frequency `• Working (Ns)` status ticks no longer snap the viewport back to the bottom while reading earlier output.
+
+  **Mobile:** session-options modal raised above the fixed mobile/tablet header (z-index 1300 vs 1200) so the close button is reachable on phones; Respawn tab controls regrouped.
+
+  **Docs:** security-architecture.md updated for the secret-gated hook bypass (including the external-proxy caveat) and the tunnel password guard; README documents auto-resume on usage limit.
+
+## 0.9.13
+
+### Patch Changes
+
+- Auto-resume on usage limit ("token pause" control) plus a set of mobile-view fixes for regressions introduced in 0.9.8.
+
+  **Auto-resume on usage limit** — new opt-in checkbox at the top of the session Respawn tab (off by default). When Claude stops because a usage limit was reached, Codeman parses the reset time from the limit message, waits until the limit lifts (plus a 2-minute safety buffer), then dismisses the rate-limit dialog (Esc) and sends "continue" so the session picks its work back up automatically. All Claude Code message formats from 1.0.x through 2.1.x are recognized ("5-hour limit reached ∙ resets 8pm", "Limit reached · resets 1pm (America/Chicago) · /upgrade…", "You've hit your weekly limit · resets Mon 12:00am", weekly date forms, and the raw API `usage limit reached|<epoch>` form). Still-limited responses re-arm the scheduler (5-minute retry loop); a pending schedule persists across Codeman restarts and re-arms on boot; respawn cycles are blocked while a limit pause is active so the cycle's `/clear` cannot wipe the paused conversation. New endpoint `POST /api/sessions/:id/auto-resume`; new SSE events `session:limitPauseScheduled`, `session:limitResume`, `session:limitResumeCancelled`; toast/notification on pause and resume, plus a live "resumes at HH:MM" status line in the modal. The Respawn tab layout was also tidied: compact single-row Update/Kickstart prompt fields and a merged options row.
+
+  **Mobile fixes (0.9.8 regressions)**:
+  - **Activity-based resize arbitration** — a desktop sizing claim now only blocks a phone's resize while that desktop has actually typed within the last 90 seconds. Previously any connected desktop tab (even one abandoned hours ago) silently discarded the phone's resize with no fallback, leaving the phone rendering a desktop-width stream in a narrow terminal: mid-word wraps, tmux dot-fill rows, overdrawn garbled text, and misplaced keyboard echo. Now an idle desktop yields the pane to the phone, and the next desktop keystroke automatically restores the desktop layout ("whoever is actively using the session wins"). Phones also re-send their dimensions every 30 seconds (visible tab only, skipped while the virtual keyboard is open) so attaching under a momentarily-active desktop self-corrects.
+  - **Keyboard accessory bar and toolbar restored on iOS** — the lift offset is measured against the layout viewport (`window.innerHeight`) again instead of the keyboard-shrunken app element; on iOS the offset computed to 0, leaving both bars hidden behind the OS keyboard with a dead black gap above it.
+  - **Removed the mobile header utility ("three dots") toggle** — the header-utilities tray stays collapsed on small viewports.
+
+## 0.9.12
+
+### Patch Changes
+
+- Documentation refresh — README catches up with the Codex run mode, plus a CLAUDE.md correction.
+
+  **README (en + zh-CN)**: Codex is now listed as a third supported AI coding CLI everywhere the docs previously said "Claude Code or OpenCode": the install requirement in Quick Start (now "any combination works", linking to the official Codex CLI docs), the Windows/WSL setup note, the renamed **Multi-CLI** feature bullet (env-prefix gating now reads `CLAUDE_CODE_*` vs `OPENCODE_*` vs `CODEX_*`), the Zod schema-validation security bullet, and the architecture mermaid diagram. The header tagline was also finalized to "Claude Code • OpenCode • Codex — One Dashboard • Any Device" in both languages.
+
+  **CLAUDE.md**: fixed a stale "Local packages" line that claimed the xterm-zerolag-input local-echo overlay had a copy embedded in `app.js` — it is single-source in `packages/xterm-zerolag-input/`, bundled to the gitignored vendor file, and only consumed by `app.js`, matching the existing single-source gotcha.
+
+## 0.9.11
+
+### Patch Changes
+
+- Fix a terminal freeze on hover (catastrophic regex backtracking) and a CSP violation that disabled the terminal's anti-throttling worker.
+
+  **Tab-freezing hover bug**: the terminal link provider's `cmdPattern` (which turns `tail -f /path`-style text into clickable links) used an empty-matchable, unbounded arg group — `(?:[^\s\/]*\s+)*` — that backtracks exponentially on real Claude output, e.g. wrapped `git commit -m "$(cat <<'EOF'` heredoc lines or aligned table rows. Hovering the mouse over such a line hung the page's main thread for minutes ("page unresponsive"). The pattern now uses non-empty tokens with bounded repetition (linear time); all intended command+path link forms still match. New `test/link-provider-regex.test.ts` extracts the shipped patterns from source and pins linear-time behavior on the killer line shapes.
+
+  **Blob worker CSP fix**: `worker-src 'self' blob:` is now always present in the CSP (previously only with `CODEMAN_GESTURE=1`). The terminal's `_safeYield` anti-throttling tick worker is created from a Blob URL and was silently blocked on every install, logging a CSP violation on each page load and disabling the worker leg of the render-yield fallback chain.
+
+## 0.9.10
+
+### Patch Changes
+
+- Self-update now restarts automatically on headless Macs supervised by a system LaunchDaemon.
+
+  New `launchd-daemon` supervisor kind: when Codeman runs under a bootstrapped, KeepAlive system-level LaunchDaemon (`/Library/LaunchDaemons/com.codeman.web.plist` — the right setup for headless Macs, where LaunchAgents never start because there is no GUI login), the updater no longer ends with "Update staged — restart Codeman to apply". It restarts rootlessly: the update script kills the server PID (passed via `--server-pid`) and launchd respawns it on the freshly built `dist/`. Detection is conservative — the daemon must be bootstrapped in the system domain AND have `KeepAlive` enabled.
+
+  Also fixed: a lingering "restart Codeman to apply" status. After a manual restart of a staged update, boot reconciliation now flips `completed-needs-manual-restart` to `completed` once the running version matches the staged target, so the Updates tab stops showing the stale instruction.
+
+## 0.9.9
+
+### Patch Changes
+
+- Codex (OpenAI CLI) run mode, Claude Model picker, and response-viewer button now opt-in.
+
+  **Codex (OpenAI CLI) run mode** (#114): new `codex` session mode alongside Claude Code and OpenCode. Sessions launch the Codex CLI via tmux with secrets injected through `tmux setenv` (`OPENAI_API_KEY`/`CODEX_API_KEY`/`CODEX_HOME` — never on the command line). Supports `--model`, `resume <id>`, and `--dangerously-bypass-approvals-and-sandbox` via the `codexConfig` payload or the new App Settings → Codex CLI tab (`codexDangerouslyBypassApprovals`). Availability surfaced at `GET /api/codex/status` with an install hint when the binary is missing. Frontend gets a "Run CX" run-mode option; Respawn/Ralph options stay Claude-only (session options open on the Summary tab for external-CLI sessions). `CODEX_*` env prefix added to the env-override allowlist.
+
+  **Claude Model picker**: App Settings → Claude CLI gains a "Claude Model" select (`claudeModel` setting) that pins the model for new Claude sessions via the case's `.claude/settings.local.json` — e.g. Fable 5 (1M context), Fable 5, Opus (1M), Opus, Sonnet, Haiku. It takes precedence over the legacy 1M Opus Context toggle. Fable 5 also added to the orchestrator default/phase model dropdowns.
+
+  **Response-viewer (eye) header button is now hidden by default** — existing users who relied on it can re-enable it under App Settings → Display → Response Viewer (`showResponseViewer`, per-device setting). A new Display toggle controls its visibility.
+
+  Also: tests made immune to a set `CODEMAN_GESTURE` env var; CLAUDE.md documents the Codex run mode and the eye-button toggle.
+
+## 0.9.8
+
+### Patch Changes
+
+- Stable HTTP contract, terminal pane-buffer rework, mobile/touch fixes, and fresh-install default cleanups.
+

 - **Effort is NOT an env var** — never carry effort as `CLAUDE_CODE_EFFORT_LEVEL`: the env var hard-locks effort and blocks in-session `/effort` switching (incl. ultracode). It flows as the dedicated `effort` payload field → `Session._effort` → `claude --effort <level>` for regular levels incl. `max` (the settings `effortLevel` key is `enum(["low","medium","high","xhigh"]).catch(undefined)` — `max` gets SILENTLY dropped there), or `claude --settings '{"ultracode":true}'` for ultracode (rejected by `--effort`). Both are soft defaults the user can override anytime. Legacy env-var entries are auto-migrated by the Session constructor and unset from tmux sessions in `applyEnvOverrides()`. See `buildEffortCliArgs()` in `session-cli-builder.ts`, tests in `test/effort-injection.test.ts`
-- **Dual-CLI prefix discipline** — Codeman supports both Claude Code and OpenCode (`claude-cli-resolver.ts` / `opencode-cli-resolver.ts`); env-var prefix is CLI-specific (`CLAUDE_CODE_*` vs `OPENCODE_*`) and the allowlist in `schemas.ts` enforces this.

 - **Zod `.optional()` rejects `null`** — accepts `undefined` only. When the frontend builds a request body with `JSON.stringify`, an explicit `null` field is preserved on the wire and fails validation with `INVALID_INPUT`. Convert `null` → `undefined` before stringifying (e.g. `field: value ?? undefined`), or declare the schema `.nullish()`. Real bugs caused: 0.6.4 (`durationMinutes` for ∞ respawn), and the same shape pattern hit `opusContext1mEnabled` in 0.6.3
-- **`xterm-zerolag-input` is duplicated** — the local-echo overlay lives in BOTH `packages/xterm-zerolag-input/src/` (published to npm as a standalone library for external consumers — see README "Published Packages") AND inline inside `src/web/public/app.js` (runtime copy the web UI actually loads, since the page ships as plain JS without a bundler). Any change to overlay behavior MUST be applied to both, or dev and prod diverge — and a public API break in the package warrants a separate version bump for `xterm-zerolag-input` in the changeset. Always test on mobile after touching it. See `docs/local-echo-overlay-plan.md`.
+- **`xterm-zerolag-input` is single-source — edit the package, then rebuild the bundle** — the local-echo overlay source lives ONLY in `packages/xterm-zerolag-input/src/` (`zerolag-input-addon.ts`; also published to npm as a standalone library — see README "Published Packages"). It is bundled (esbuild → IIFE, with appended `window.LocalEchoOverlay` aliases) into the **gitignored** `src/web/public/vendor/xterm-zerolag-input.js` by `scripts/postinstall.js` (for dev/`tsx`) and into `dist/.../vendor/` by `scripts/build.mjs:50` (for prod). `app.js` only **consumes** it via `new LocalEchoOverlay(terminal)` — there is NO inline copy to keep in sync. So: change behavior in the package source, then re-run the bundle step (`npm install` reruns postinstall; `npm run build` for prod); **never hand-edit `app.js` for overlay behavior or commit the gitignored vendor bundle**. A public-API break in the package still warrants a separate `xterm-zerolag-input` version bump in the changeset. Always test on mobile after touching it. See `docs/local-echo-overlay-plan.md`.
 - **Default bind is loopback-only; non-loopback without a password starts but warns** — since COD-29 (PR #107) the web server defaults to `--host 127.0.0.1` (was `0.0.0.0`). As of **0.9.0** binding a non-loopback host (`--host`/`-H`/`CODEMAN_HOST`) without `CODEMAN_PASSWORD` **no longer refuses to start — it starts and prints a loud warning** listing the fixes (set `CODEMAN_PASSWORD`, bind loopback + tunnel/`tailscale serve`, or `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` to acknowledge → terser note). Host classification is `isLoopbackBindHost()` in `network-auth-policy.ts`; the warn-vs-start logic is in `server.ts` `start()`; flags wired in `cli.ts`. ⚠️ Operational note: the production systemd unit runs `node dist/index.js web --https` with no `--host`, so it binds **localhost only** — reach it remotely via `tailscale serve`/tunnel to `127.0.0.1`, or add `Environment=CODEMAN_HOST=0.0.0.0` + `Environment=CODEMAN_PASSWORD=…` to `~/.config/systemd/user/codeman-web.service`. A loopback bind is reachable through a same-host tunnel (cloudflared/tailscale → `127.0.0.1`) but NOT by a browser hitting the box's LAN IP. Auth user defaults to `admin`. **Full model: `docs/security-architecture.md`.**
 - **Instance isolation / multi-instance attach danger** — data dir (`~/.codeman`) and tmux socket (`tmux -L codeman`) are PROCESS-WIDE and shared by every Codeman on the machine, derived from `CODEMAN_INSTANCE` via `src/config/instance.ts` (`getDataDir()`/`dataPath()`/`DEFAULT_TMUX_SOCKET`). ⚠️ A 2nd instance on the SAME socket **discovers and attaches PTYs to the first instance's live sessions** (`tmux -L codeman attach-session …`), resizing/mutating them — `$HOME` isolation is NOT enough (tmux is system-global). To run two instances, give each a distinct `CODEMAN_INSTANCE` (scopes BOTH dir+socket: `~/.codeman-<name>` + `-L codeman-<name>`), or set `CODEMAN_TMUX_SOCKET` + `CODEMAN_DATA_DIR` individually. **`CODEMAN_INSTANCE` defaults to empty = the production layout (`~/.codeman`, `-L codeman`, port 3000)**, so this branch is safe to ship to master without disturbing existing installs. To run THIS beta alongside prod, launch with `scripts/run-beta.sh` (`CODEMAN_INSTANCE=beta` + `CODEMAN_PORT=5000`) — it never collides with prod's data dir/socket/port. Any new `~/.codeman/...` path MUST go through `dataPath()`, never `join(homedir(), '.codeman', …)`.
+- **Headless screenshots: `deviceScaleFactor` MUST be 1, and write unique filenames** — `scripts/capture-real-overview.mjs` (drives a live session in headless Chromium → overview PNG). Two traps, both observed 2026-06-14: **(1) DSF=2 doubles the console font.** xterm's WebGL renderer draws terminal glyphs at ~2× their nominal size under `deviceScaleFactor: 2`, while STILL reporting nominal cell dims (`terminal.cols`/`_renderService.dimensions.css.cell` say 8px/187cols — they lie), so it's invisible to any internal measurement and only the pixels reveal it. The HTML chrome (header/toolbar) is unaffected → ONLY the console font looks comically large. Default to **DSF=1** (script does); the image is 1× res but the font is true-to-browser. **(2) Stable filenames → stale renders.** Overwriting a fixed path (`claude-overview.png`) in place leaves OS image viewers (eog/feh) — and any HTTP client behind a long/`immutable` cache — showing the OLD render; the user reads it as "the fix didn't work". The script now mints a timestamped `claude-overview-<ts>.png` per run. ⚠️ This was a LOCAL image-viewer cache, NOT a Codeman serving bug: `file-routes` previews send `Cache-Control: no-cache` and `/api/screenshots/:name` sends none. The one real Codeman-side footgun: `server.ts` serves non-content-hashed static assets `public, max-age=31536000, immutable`, and `cacheBustAssets()` only rewrites `.js`/`.css` refs — a stable-named **image** referenced from public/ would go stale on overwrite. Reflect the per-device UI to match a real device when capturing: seed `localStorage` `codeman:skin`, `codeman-font-size`, and the desktop `codeman-app-settings` blob (the plan-usage chip is a per-device display key deleted from the server payload — a fresh browser hides it unless seeded; close side panels for a full-width terminal).
 
 **Import conventions**: Utils from `./utils`, types from `./types` (barrel), config from specific `./config/*` files.

 **Idle detection**: Multi-layer (completion message → AI check → output silence → token stability). See `docs/respawn-state-machine.md`.
 
+**Auto-resume on usage limit** ("token pause" control, opt-in per session, top of the Respawn tab): when Claude halts on a subscription limit ("5-hour limit reached ∙ resets 8pm" and all 1.0.x–2.1.x variants), `usage-limit-patterns.ts` (pure, unit-tested) parses the reset time from cleaned output; `SessionAutoOps` arms a timer for reset+2min, then sends Esc (dismisses the rate-limit dialog) + `continue`. Still-limited responses re-arm the loop (5-min retry on stale times); a `working` transition cancels it. Claude-mode only (detection rides `_processExpensiveParsers`). Persists/recovers via `SessionState.autoResumeEnabled`/`autoResumeAt`; respawn cycles are blocked while paused (`isLimitPaused` guard in `onIdleDetected` — prevents `/clear` from wiping the paused conversation). Endpoint: `POST /api/sessions/:id/auto-resume`; SSE: `session:limitPauseScheduled`/`limitResume`/`limitResumeCancelled`. Tests: `test/usage-limit-patterns.test.ts`, `test/session-auto-resume.test.ts`.
+
+**Plan-usage chip** (statusLine telemetry, opt-in `showPlanUsageLimits`, default OFF): Claude Code (v2.1.80+) pipes a JSON blob to a configured `statusLine.command` on each render; on Pro/Max it carries a `rate_limits` object (`five_hour`/`seven_day` windows only — no Opus weekly field — each `{used_percentage 0-100, resets_at epoch-SECONDS}`). Codeman injects its OWN statusLine exporter (`generateStatusLineCommand()` in `hooks-config.ts`, identified by the `/api/status-telemetry` marker — it only ever adds/updates/removes a statusLine that is *ours*, never a user's hand-authored one) that POSTs the blob to `POST /api/status-telemetry`. That route (auth-exempt like `/api/hook-event` — localhost-only, hook-secret-gated under a tunnel) parses via `usage-telemetry.ts` (pure, unit-tested), broadcasts SSE `session:statusTelemetry` (de-duped per session by `telemetrySignature` since the statusline fires on every assistant message), and returns a compact plain-text footer for the exporter to **print-through** (so injecting our statusLine doesn't blank the in-terminal footer). `plan-usage-latest.ts` holds the process-wide last value, replayed in the SSE init snapshot (`getLightState`) so the header chip (`#planUsageChip`, toggled by `showPlanUsageLimits` in settings-ui.js) renders immediately on page load / reconnect without per-browser localStorage. Claude-mode only. **Distinct from auto-resume** (which reacts to the limit *message*; this proactively shows the live %). Design: `docs/usage-limits-display-plan.md`. Tests: `test/usage-telemetry.test.ts`.
+
 **Orchestrator**: State machine that turns a user goal into a phased plan and drives it to completion: `idle → planning → approval → executing → verifying → (replanning) → completed/failed`. `OrchestratorLoop` (engine) delegates plan generation to `orchestrator-planner` and per-phase verification gates to `orchestrator-verifier`, executing phases via team agents/`task-queue`. State persists under the `orchestrator` key in `state.json`. Distinct from Ralph (single-session autonomous loop) — orchestrator coordinates multi-phase, multi-agent execution.

+**External CLI modes (OpenCode, Codex)**: `isExternalCliMode()` in `session.ts` gates Claude-specific behavior — Ralph tracker, BashToolParser, token/CLI-info parsing, and ❯-prompt readiness detection are all skipped (these CLIs render their own TUIs; readiness = output stabilization instead). Both modes **require tmux — no direct PTY fallback** — because secrets are injected via `tmux setenv`, never on the spawn command line: OpenCode gets `OPENCODE_CONFIG_CONTENT` etc., Codex gets `OPENAI_API_KEY`/`CODEX_API_KEY`/`CODEX_HOME` (`setCodexEnvVars` in `tmux-manager.ts`). Codex specifics: command built by `buildCodexCommand()` (`--model`, `resume <id>`, `--dangerously-bypass-approvals-and-sandbox` from the `codexConfig` payload / `codexDangerouslyBypassApprovals` app setting; `renderMode` is schema-coerced to `'hybrid'`, the only supported mode); tmux exports `COLORTERM=truecolor` + unsets `NO_COLOR` (other modes unset `COLORTERM`); availability via `GET /api/codex/status` — session/quick-start routes fail with `OPERATION_FAILED` and an install hint (`npm install -g @openai/codex`) when the binary is missing. Frontend: run-mode dropdown → `runCodex()` in `session-ui.js` ("Run CX" label), App Settings → Codex CLI tab; Respawn/Ralph options are Claude-only, so session options open on the Summary tab for external CLI sessions. Tests: `test/run-mode-ui.test.ts` (vm-sandbox harness, no real DOM).

+**Self-update** (App Settings → Updates): in-app updater for **git-clone installs** supervised by systemd/launchd. Supervisors: `systemd` (user unit), `launchd` (GUI LaunchAgent, gui-domain kickstart), `launchd-daemon` (KeepAlive system LaunchDaemon on headless Macs — restarts rootlessly by killing the server PID and letting launchd respawn it; detected only when the daemon is bootstrapped AND KeepAlive), else `none` → "restart manually" message; on next boot a manual-restart status auto-completes when the running version matches the target. The update restarts the very process running it, so the real work runs in a DETACHED `scripts/self-update.sh` (`git checkout <release tag> && npm install && npm run build && restart`) that outlives the restart; it writes progress to `dataPath('update-status.json')`, which the browser polls across the connection drop.

+
+**Attachments** (live external document references; COD-37/#119 core, COD-38/#120 previews, COD-39/#121 history): all wiring in `file-routes.ts`. **Registry** (`attachment-registry.ts`): an **in-memory** map of a stable `attachmentId` → an absolute, `realpath`-resolved, extension-allowlisted file path, so browser requests (`GET /api/sessions/:id/attachments/:attachmentId/raw`) never carry arbitrary absolute paths; `POST /api/sessions/:id/attachments` registers one. **Magic links** (`attachment-magic.ts`): parses `codeman://attach?...` out of terminal output — ⚠️ this scanner is prompt-injectable, so the scan path is **force-confined to the session workspace** (a hostile prompt could otherwise make it read arbitrary host files over SSE); emits the `attachment:detected` SSE event. Security gate is an extension **allowlist** (`isSupportedAttachmentExtension`, in the registry/magic modules), not a blocklist; a separate path layer (`config/attachment-guard.ts`) confines reads to the workspace (`attachmentConfineToWorkspace`) and blocks sensitive trees (`/root`, `/etc`). **Previews + thumbnails** (COD-38): `:attachmentId/preview` + `:attachmentId/thumbnail` (and the workspace-file equivalents `file-preview`/`file-thumbnail`) render Office docs/PDFs via external converters (`pdftoppm` / LibreOffice `soffice` / Word-COM `powershell`); `document-preview-cache.ts` is a shared disk cache (de-dups *identical* in-flight inputs), `document-thumbnailer.ts` does best-effort first-page images, and `document-conversion-limiter.ts` is a **global converter-spawn concurrency cap** (`runWithConversionLimit`) — without it, N distinct large docs detected at once fork N multi-minute converter processes = a localhost fork-bomb-shaped resource-exhaustion vector. **History drawer** (COD-39): `session-attachment-history.ts` tracks the last `ATTACHMENT_HISTORY_LIMIT` (100) attachments per session (`Session._attachmentHistory`, persisted via `SessionState.attachmentHistory`, replayed so externals re-register on reconnect); `GET /api/sessions/:id/attachments` is the list endpoint. ⚠️ The history drawer's launcher button is desktop-only — hidden on phones (regression-guarded; see `mobile-header-buttons-policy` test). Session-local files keep using the existing workspace-scoped `file-routes` paths; the registry is only for explicit live externals.
+
+**Ultracode / Workflow-run visualization** (opt-in `showUltracodeAgents`, default OFF; released 1.1.2): the Workflow tool ("ultracode") writes a run-state JSON per run at `~/.claude/projects/<projHash>/<sessionUuid>/workflows/wf_*.json`. `workflow-run-watcher.ts` (STANDALONE — deliberately never imports/touches `subagent-watcher.ts`; disjoint directory tree, separate singleton) globs that tree via periodic poll + per-run chokidar watcher with per-file mtime skip, and broadcasts SSE `workflow:run_discovered`/`run_updated`/`run_removed`. The watcher is only started when the setting is on (`server.ts` gates on `showUltracodeAgents`). Served via `GET /api/workflows` (optional `?minutes=` filter) and `GET /api/workflows/:runId`. Frontend `ultracode-panel.js` renders a docked master-detail view (LEFT: runs + phases; RIGHT: per-agent tokens + tool-calls; click an agent card → its live transcript via client-side `agentId` join). **Additionally**, `ultracode-windows.js` auto-pops a draggable **floating window per active run** (gated on the same `showUltracodeAgents` setting), connected by a glowing line to the originating session tab (resolved by `session.claudeSessionId === run.sessionUuid`) — same line idiom as subagent windows, drawn into the shared `#connectionLines` SVG from the tail of `_updateConnectionLinesImmediate`. The window auto-closes ~8s after its run finishes; explicit dismissals are remembered. Types: `src/types/workflow-run.ts`. Config: `src/config/workflow-config.ts`.
 
 **Port interfaces**: Routes declare dependencies via port interfaces (`src/web/ports/`). Routes use intersection types (e.g., `SessionPort & EventPort`).

-**Z-index layers**: subagent windows (1000), plan agents (1100), log viewers (2000), image popups (3000), local echo overlay (7).
+**Z-index layers**: subagent windows (1000), plan agents (1100), mobile/tablet fixed header (1200, `mobile.css`), modals on ≤768px (1300 — must beat the fixed header or the modal close button is buried; bug fixed in `b8cb467`), log viewers (2000), image popups (3000), local echo overlay (7).
 
 **Multi-monitor button** (header, top-right; the notification bell it sits beside stays hidden — notifications live in Settings → Notifications). `app.launchMultiMonitor()` (in `panels-ui.js`) POSTs `/api/system/span-displays`, which spawns `scripts/span-codeman.sh` — a fresh, maximized browser `--app` window sized to the union of all displays (macOS; needs "Displays have separate Spaces" OFF). Supports the gesture layer's in-page floating session panels dragging across the physical monitor seam. **Opt-in:** hidden by default; enable under App Settings → Display → **Header Displays** ("Multi-monitor Button", `showMultiMonitorButton`). The button carries a `btn-multimonitor--hidden` class in the template; `renderIndexHtml` strips that class at render when the setting is on (a unique class token, not a brittle match on the aria-label/style copy), and `applyHeaderVisibilitySettings()` toggles the same class live on save. Solo (detached) windows hide it via `body.solo-mode`.
 
+**Response-viewer (eye) button** (header) is likewise **hidden by default** — enable under App Settings → Display → **Response Viewer** (`showResponseViewer`). Purely client-side (no `renderIndexHtml` step): the template ships with `btn-response-viewer-header--hidden` and `applyHeaderVisibilitySettings()` (settings-ui.js) toggles it after settings load. Hiding must go through that marker class — the base rule is `display:inline-flex !important`, so an inline style can't override it. `showResponseViewer` is in the `displayKeys` per-device set (settings-ui.js), so it does NOT sync across devices.
+
 **Gesture control** (the camera hand-tracking overlay) is **opt-in, default OFF**, under App Settings → Display → **Input** (`gestureControlEnabled`). `CODEMAN_GESTURE=1` makes the feature *available* on the instance (CSP widening + `/gesture/` assets) and sets `window.__codemanGestureAvailable` (the Input section only shows when set); the overlay bundle is injected by `renderIndexHtml` **only when the setting is enabled**, so that method is `async` and reads `settings.json` via `readSettings(true)` — the `true` forces a **fresh** read (bypassing the 2s `_settingsCache`), because a post-save reload happens within that TTL and the cached value would otherwise render the pre-toggle state. Toggling the setting reloads the page (the bundle is render-injected).
 
 **Gesture-control source lives in-repo** at `packages/gesture-control/` (workspace package `codeman-gesture-control`, was the standalone `Ark0N/codeman-gesture-control` repo). The transport-agnostic core is `src/gesture/*` (MediaPipe GestureRecognizer → One-Euro-filtered cursor → pinch state machine); `src/codeman/entry.ts` is the Codeman *consumer* that maps grab/drag/drop onto real `.session-tab`/toolbar buttons and is the bundle entry. **Edit there, then run `npm run build:gesture`** (`scripts/build-gesture-bundle.mjs` → esbuild bundles `entry.ts`, MediaPipe JS included, into `src/web/public/gesture/gesture-codeman.js`) and **commit the regenerated bundle** — the committed bundle is what dev/`tsx` serves (no bundler at runtime), and `scripts/build.mjs` reruns the same step so prod always reflects current source. The MediaPipe **wasm + model** are NOT bundled — loaded at runtime from same-origin `/gesture/wasm` + `/gesture/gesture_recognizer.task`, fetched by `scripts/fetch-gesture-assets.mjs` (gitignored, see Gotchas). `entry.ts` mounts `window.__codemanGesture = new GestureBridge()` idempotently at module-eval. A standalone vite playground (`npm run dev` in the package — fake tabs, no Codeman) lets you iterate on gesture *feel* in isolation. ⚠️ Keep `MP_VERSION` in `fetch-gesture-assets.mjs` in sync with `@mediapipe/tasks-vision` in `packages/gesture-control/package.json`.
 
+**Theme skins** (App Settings → Display): the `skin` setting selects a palette via a `data-skin` attribute on `<html>`. Values: `daylight-blue` (default), `daylight-green`, `og` (OG Codeman). CSS lives under `[data-skin="…"]` blocks in `styles.css`. To avoid a flash-of-wrong-theme, an **inline pre-paint script** in `index.html` (`<head>`) reads `localStorage['codeman:skin']` and sets `data-skin` before first paint; `settings-ui.js` `applyTheme()`/`applyTerminalSkin()` apply it live on save and keep the standalone `codeman:skin` key + the settings object in sync. `skin` is a **per-device/client-only** setting — it's destructured OUT of the server payload (settings-ui.js, alongside `localEchoEnabled`/`cjkInputEnabled`/`extendedKeyboardBar`), so it does NOT sync across devices.
+
 **Respawn presets**: `solo-work` (3s/60min), `subagent-workflow` (45s/240min), `team-lead` (90s/480min), `ralph-todo` (8s/480min), `overnight-autonomous` (10s/480min).
 
 **Keyboard shortcuts**: Escape (close), Ctrl+? (help), Ctrl+W (kill), Ctrl+Tab (next), Alt+1-9 (switch tab), Ctrl+Shift+{/} (move tab left/right), Shift+Enter (newline), Ctrl+L (clear), Ctrl+Shift+R (restore size), Ctrl+Shift+V (voice input), Ctrl/Cmd +/- (font).

+**Never run the bare full suite** (`npm test` with no file argument): the default config includes the browser-driven suites (`test/mobile/**` and 3 other Playwright tests), which need a live server + chromium + environment-specific PNG baselines and will fail/hang locally.

+**Config**: Vitest with `globals: true`, `fileParallelism: false`. Timeout 30s, teardown 60s. `config/vitest.ci.config.ts` = same minus the browser/perf excludes — keep the two configs in sync when changing shared options.
 
-**Safety**: `test/setup.ts` snapshots pre-existing tmux sessions and never kills them. Only `registerTestTmuxSession()` sessions get cleaned up.
+**Tmux safety**: under vitest (`VITEST` env var, set automatically), `TmuxManager` no-ops ALL shell commands and becomes a pure in-memory mock — tests physically cannot create/kill/attach real tmux sessions (`IS_TEST_MODE` in `src/tmux-manager.ts`). `test/setup.ts` additionally strips `CODEMAN_PASSWORD`/`CODEMAN_USERNAME` so auth state from the running instance can't leak into tests.

+

+
+Report privately via **GitHub's private vulnerability reporting**:
+the repository's **Security** tab → **Report a vulnerability**
+(<https://github.com/Ark0N/Codeman/security/advisories/new>). This opens a private

+
+> Maintainer note: enable *Settings → Code security and analysis → Private
+> vulnerability reporting* so this channel is live.
+
+When reporting, please include: affected version/commit, the deployment shape
+(loopback-only, `CODEMAN_PASSWORD` set, tunnel/`tailscale serve`, custom
+reverse proxy), reproduction steps, and impact. We aim to acknowledge within a
+few days. Coordinated disclosure is appreciated — we'll agree a disclosure
+timeline with you once impact is confirmed.
+
+### In scope
+- Authentication / session-cookie bypass when `CODEMAN_PASSWORD` is set
+- DNS-rebinding, CSRF/CSWSH, or Origin/Host-guard bypass reaching state-changing routes
+- Remote code execution reachable **without** local OS access (e.g. via a browser, a tunnel, or a foreign origin)
+- Path traversal / arbitrary file read or write through the HTTP API
+- Supply-chain integrity of the in-app self-updater
+
+### Out of scope (by design — see Known limitations)
+- Anything requiring an already-trusted **same-machine, same-uid** process. Codeman trusts the local OS user it runs as; a peer process of that user is already inside the boundary.
+- Running an authless instance bound to a non-loopback host after dismissing the startup warning (you explicitly acknowledged it).
+- The default loopback + no-password posture itself (it is reachable only from the same machine).
+
+## Trust model (summary)
+
+- **Loopback by default.** Binds `127.0.0.1`; 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 concrete fixes.
+- **Always-on Host + Origin guards.** Block DNS-rebinding and cross-site state-changing requests even on the no-auth loopback install (a missing Origin is allowed so CLI/hooks work).
+- **Optional auth.** HTTP Basic via `CODEMAN_USERNAME`/`CODEMAN_PASSWORD`; success issues an opaque server-side 256-bit cookie. Per-IP rate limiting on failures.
+- **Hardened file serving, tmux launch, transport headers, and multi-instance isolation** — see the full architecture doc.
+
+## Known limitations and accepted risk
+
+A 1.0 release is an implicit statement that the documented model *is* the model, so
+these residuals are stated explicitly. Most sit **inside the same-uid OS trust
+boundary** or behind the always-on Origin guard; they matter mainly for
+shared-host, multi-user, or tunneled deployments.
+
+- **Self-update trusts an unsigned release tag.** The in-app updater does `git checkout <tag> && npm install` (lifecycle scripts run) of a tag matched only by name shape, from whatever `origin` points to — no signature/commit verification. Treat the updater as trusting your `origin` remote and your release pipeline. (Hardening tracked for 1.0.)
+- **CSP ships `'unsafe-inline'`.** Inline handlers mean the Content-Security-Policy is defense-in-depth only; all AI-/file-derived sinks are escaped, but a future missed escape would be executable.
+- **`workingDir` is unconstrained.** A session may be created with any absolute working directory (e.g. `/`), which becomes the file-route boundary for that session. Scope it to trusted paths on shared hosts.
+- **Hook-event auth exemption is loopback-IP-based.** `POST /api/hook-event` is exempt from auth for loopback callers; because tunnels (cloudflared / `tailscale serve`) terminate at `127.0.0.1`, a loopback-terminating tunnel inherits the exemption. Set `CODEMAN_PASSWORD` and prefer a tunnel that preserves the client identity if this matters.
+- **Session cookie is not bound to client IP/UA on reuse, and refreshes without an absolute cap.** A stolen cookie replays until its idle TTL elapses.
+- **Multi-instance tmux socket is process-wide.** Two Codeman instances on the same `CODEMAN_INSTANCE` share a tmux socket and can attach each other's live sessions — isolate with distinct `CODEMAN_INSTANCE` values.
+- **The live log-tail route reads `/var/log` and `~/logs`** in addition to the session working directory (read-only) — a deliberate choice for tailing system/app logs. On a password-protected remote deployment an authenticated user can therefore read those roots outside their session. See `docs/security-architecture.md` §5.
+
+Recent hardening (this release): web-push subscription endpoints are restricted
+to https public hosts (SSRF guard — rejects internal/metadata IPs, validated at
+subscribe and send time), and tmux session names discovered on the shared socket
+are validated against the safe-name pattern before reaching any shell call site.
+
+For the detailed rationale, defenses, and recommended secure setups, see
+[`docs/security-architecture.md`](docs/security-architecture.md).

+# HTTP API Reference
+
+Codeman's HTTP API is a **stable contract** as of 1.0 — see
+[`versioning-policy.md`](versioning-policy.md) for the SemVer guarantee. This page
+defines the response envelope, status codes, error codes, versioning, and the SSE
+event channel.
+
+## Versioning
+
+- The stable, public surface is served under **`/api/v1/...`**. Pin external
+  clients to this prefix.
+- The unversioned **`/api/...`** paths are a permanent alias of the current
+  version (what the bundled web UI uses). They are kept working, but new external
+  integrations should use `/api/v1`.
+- Breaking changes to the contract ship under a new prefix (`/api/v2`); `/api/v1`
+  keeps its semantics. Additive changes (new endpoints, new optional fields, new
+  error codes) are non-breaking and may appear in a minor release.
+- The implementation rewrites `/api/v1/*` → `/api/*` at the server level
+  (`rewriteApiV1Url` in `src/web/server.ts`).
+
+## Response envelope
+
+Every JSON response uses one uniform envelope, applied centrally by a
+`preSerialization` hook (`src/web/server.ts`) — handlers return bare data and the
+hook wraps it:
+
+**Success** — HTTP `2xx`:
+
+```json
+{ "success": true, "data": <payload> }
+```
+
+`data` is the endpoint's payload (object, array, or value). Endpoints with no
+payload return `{ "success": true, "data": {} }`.
+
+**Error** — HTTP `4xx`/`5xx`:
+
+```json
+{ "success": false, "error": "human-readable message", "errorCode": "NOT_FOUND" }
+```
+
+`ApiResponse<T>` in `src/types/api.ts` is the canonical type.
+
+> Non-JSON endpoints are exempt from the envelope: `GET /api/sessions/:id/file-raw`,
+> `GET /api/sessions/:id/tail-file` (SSE), `GET /api/download`,
+> `GET /api/screenshots/:name`, `GET /q/:code` (QR redirect), and the
+> `GET /ws/sessions/:id/terminal` WebSocket upgrade.
+
+## Error codes → HTTP status
+
+The single source of truth is `ErrorStatus` / `httpStatusForErrorCode()` in
+`src/types/api.ts`. Clients should branch on `errorCode` (stable) and may rely on
+the HTTP status.
+
+| `errorCode` | HTTP | Meaning |
+|-------------|------|---------|
+| `INVALID_INPUT` | 400 | Malformed request / failed validation |
+| `UNAUTHORIZED` | 401 | Authentication required or failed |
+| `NOT_FOUND` | 404 | Resource does not exist |
+| `SESSION_BUSY` | 409 | Session is busy |
+| `CONFLICT` | 409 | Conflicts with current state (e.g. already running) |
+| `ALREADY_EXISTS` | 409 | Resource already exists |
+| `OPERATION_FAILED` | 422 | Well-formed but could not be completed |
+| `RATE_LIMITED` | 429 | Too many requests |
+| `INTERNAL_ERROR` | 500 | Unexpected server error |
+
+Adding a new error code is non-breaking; removing or renaming one is a major change.
+
+## Authentication
+
+Optional HTTP Basic (`CODEMAN_USERNAME`/`CODEMAN_PASSWORD`) → opaque
+`codeman_session` cookie. When enabled, unauthenticated requests get
+`401 UNAUTHORIZED`; rate-limited requests get `429 RATE_LIMITED`. See
+[`security-architecture.md`](security-architecture.md).
+
+## SSE event channel
+
+`GET /api/events` is a Server-Sent Events stream (`text/event-stream`); each
+message is `event: <name>` + `data: <json>`. The event-name registry
+(`src/web/sse-events.ts`, mirrored in `src/web/public/constants.js`) is part of
+the stable contract — event names are not renamed without a major bump. An
+optional `?sessions=<id,...>` filter suppresses only the high-volume terminal
+stream; lifecycle/metadata events are delivered to all clients regardless.
+
+## Consuming from JavaScript
+
+The bundled frontend reads responses through `_apiJson()`
+(`src/web/public/api-client.js`), which unwraps `{success:true,data}` → `data` and
+returns `null` on a non-2xx / `{success:false}` response. External clients should
+do the same: check the HTTP status (or `body.success`), then read `body.data`.

+the `/root` and `/etc` trees, extendable via `attachmentBlockedPaths` /
+`CODEMAN_ATTACHMENT_BLOCKED_PATHS`) on every request. Unlike the workspace file
+routes, attachments are intentionally **cross‑workspace** — so the effective gate
+is the blocklist + a 6‑extension allowlist (`png/pdf/docx/pptx/md/txt`), not
+realpath containment.
+
+Two registration paths, with **different trust**:
+
+- **Explicit `POST /api/sessions/:id/attachments`** (and `codeman attach`, which
+  POSTs directly inside a managed session) — a deliberate, Origin‑guarded HTTP
+  request. Allowed cross‑workspace (subject to the guard). This is the supported
+  path for codeman‑publish and the `~/.codeman` review‑card loop.
+- **Terminal `codeman://attach?path=…` magic links** — scanned passively from
+  session output. Terminal output is **attacker‑influenceable** (a prompt‑injected
+  session can print an arbitrary path), and registration here is server‑side with
+  no Origin gate and broadcasts the `rawUrl` over SSE to all clients. This path is
+  therefore **force‑confined to the session workspace** (`forceWorkspaceConfinement`
+  in `registerExternalAttachment`, wired in `WebServer.registerAttachment`),
+  regardless of the global confine setting — a passive magic link cannot expose a
+  file outside the session's own workspace. Cross‑workspace attach must go through
+  the explicit POST path above.
+
+### SSE log‑tail route — intentional extra read roots
+
+The live file‑tail SSE route (`FileStreamManager`, used to stream a growing log
+into the UI) does **not** use `validateSessionFilePath`; it has its own validator
+with a deliberately **wider** allowlist: the session `workingDir` **plus two
+read‑only log roots — `/var/log` and `~/logs`** — so operators can tail
+system/app logs. `/tmp` is intentionally excluded (world‑writable). Like the
+other routes it `realpath`s the target and re‑checks right before spawning `tail`
+(TOCTOU guard), and it is read‑only. This is the one place the per‑session
+boundary is intentionally relaxed; on a password‑protected remote deployment an
+authenticated user can therefore read `/var/log` and `~/logs` outside their
+session dir. (Security review M5: this divergence is by design and is now
+documented here rather than silently diverging from the per‑session claim above.)

+# Ultracode / Workflow Agent Visualization — Design & Implementation Plan
+
+> **Status: IMPLEMENTED (2026-06-15, rev. 3) — Phases 1–3 shipped & verified; Phase 4 (live-transcript link) deferred.** A dedicated, opt-in **master-detail tab** (`showUltracodeAgents`, default OFF) shows ultracode/Workflow runs as Claude Code's "working agents" TUI: LEFT = runs + phases (selectable tasks), RIGHT = each run's agents with model, live state, **tokens burned**, and **tool calls**.
+>
+> ### What rev. 3 changed vs. rev. 2 (decided during implementation against on-disk truth)
+> 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.

+# Plan Usage Limits Display — Design & As-Built
+
+> **Status: SHIPPED — deployed to prod + pushed to master, not yet released (2026-06-14).** Opt-in via App Settings → Display → **Plan Usage Limits** (`showPlanUsageLimits`, default OFF). Commits `c82f6c8` (feature) → `4d9d93d` (end-to-end fixes) → `eae225b` (per-user reconcile) → `95fb5fc` (init-snapshot replay). Full suite green (2869), CI green. No changeset/version bump yet.
+>
+> Two surfaces from one `statusLine` callback:
+> - **Header chip** (top-right) — account-wide **plan limits**: `5h 35% · 7d 38%`, per-window green/yellow/red.
+> - **In-terminal statusline footer** — the **current session's** status: `Opus 4.8 (1M context)  in:562,411 out:1,188  ctx:56%`.
+>
+> The `rate_limits` JSON schema below was **empirically confirmed** against Claude Code 2.1.177 on a Claude Max account; see the Verification appendix to reproduce.
+
+## Problem
+
+Codeman had no proactive view of how much of the Claude subscription is left. It only learned about limits **reactively**: `usage-limit-patterns.ts` regex-scrapes ANSI-stripped terminal output for footer strings like `5-hour limit reached ∙ resets 8pm`, extracting only the **reset time**, and only *after* Claude has already stalled. There was no "73% of your 5-hour limit used" anywhere.
+
+We wanted a live, always-visible gauge so the operator can see a wall coming and pace overnight/autonomous runs — without hijacking the in-terminal statusline, which should keep showing the current session's status.
+
+## Data source: the statusline `rate_limits` JSON
+
+Claude Code (**v2.1.80+**; prod box runs **2.1.177**) pipes a JSON blob to a configured `statusLine.command` on stdin after each render. On Pro/Max subscriptions that blob includes `rate_limits`. **This is the only channel that exposes plan-limit data** (see rejected alternatives) — so the feature *must* set a statusLine command, which is why the footer is also reconstructed by it (below).
+
+### Confirmed schema (real captured payload)
+
+```jsonc
+"rate_limits": {
+  "five_hour": { "used_percentage": 15, "resets_at": 1781409000 },  // → 2026-06-14T03:50:00Z
+  "seven_day": { "used_percentage": 34, "resets_at": 1781827200 }   // → 2026-06-19T00:00:00Z
+}
+```
+
+| Field | Type | Notes |
+|-------|------|-------|
+| `rate_limits.five_hour.used_percentage` | `number` 0–100 | Integer-valued in practice; treat as `number`, don't assume decimals. |
+| `rate_limits.five_hour.resets_at` | `number` | **Epoch SECONDS** (10 digits). `×1000` for a JS `Date`. |
+| `rate_limits.seven_day.{used_percentage,resets_at}` | same | |
+
+**Confirmed facts & gotchas:**
+
+- **Only two windows exist: `five_hour` and `seven_day`.** There is **no separate Opus-weekly field**, even on a Max/Opus account.
+- `rate_limits` is **absent on the first render**, **present after the first API response**. UI degrades to "no chip yet."
+- statusLine fires **only in interactive TUI mode**, never `--print`. Fine — Codeman sessions are interactive TUIs (and so are Codeman-spawned ones in tmux).
+- **Subscriber-gated.** Absent for API-key / non-subscriber auth.
+
+### Bonus telemetry in the same payload — used for the footer
+
+The same stdin object also carries `model.display_name`, `context_window.{used_percentage, total_input_tokens, total_output_tokens, …}`, `cost.total_cost_usd`, `effort.level`, etc. The shipped feature uses **model + token totals + context %** to build the in-terminal footer (so the statusline stays useful even though we own it). The endpoint also broadcasts `contextUsedPercentage`/`costUsd`/`modelDisplayName` alongside the limits for future chip tooltips.
+
+### Alternatives considered & rejected
+
+| Source | Why not |
+|--------|---------|
+| OAuth endpoint `api.anthropic.com/api/oauth/usage` | Undocumented, aggressively rate-limited, needs the **encrypted** OAuth token. Only worth it for *dollar spend*. |
+| `/usage` slash command | Interactive-only, no programmatic output. |
+| On-disk `~/.claude/` files | No usage state persisted (only `daemon.status.json` = auto-updater supervisor). |
+| CLI flag (`claude usage` / `--check-usage`) | Does not exist. |
+| `StopFailure` hook | Carries only an `error_type` on *failure* — no live percentages. |
+
+## As-built architecture
+
+```
+Claude TUI (any Claude session, incl. linked-case/real-repo sessions)
+  │  renders statusline after each assistant msg (+ /compact, mode change)
+  ▼
+statusLine.command (settings.local.json)  ──reads stdin JSON──▶
+  curl -sk POST $CODEMAN_API_URL/api/status-telemetry  {sessionId, data}
+  (X-Codeman-Hook-Secret: $(cat $CODEMAN_HOOK_SECRET_FILE))
+  │  ◀── HTTP 200 text/plain = current-SESSION status string ──┘
+  ▼
+printf '%s' "$body"  →  in-terminal footer: "Opus 4.8 (1M context)  in:… out:…  ctx:…%"
+
+server (status-telemetry-routes.ts):
+  parse rate_limits  → (if changed) store last-known + broadcast SSE session:statusTelemetry  → header chip
+  parse model/tokens/ctx → return the session-status footer string
+  ▼
+app.js: _onSessionStatusTelemetry → chip (per-window colors) + localStorage save
+        handleInit → chip from init-snapshot planUsage (fresh-load replay)
+```
+
+### 1. The exporter — `generateStatusLineCommand()` in `hooks-config.ts`
+
+Mirrors the hook `curlCmd()`. Reads the stdin JSON, POSTs `{sessionId, data}` to a **fixed** loopback path, and prints the response body back to stdout (print-through, so the footer stays useful). The managed-session env carries `$CODEMAN_SESSION_ID` / `$CODEMAN_API_URL` / `$CODEMAN_HOOK_SECRET_FILE` (from `tmux-manager.buildEnvExports()`).
+
+```bash
+INPUT=$(cat 2>/dev/null || echo '{}'); \
+printf '{"sessionId":"%s","data":%s}' "$CODEMAN_SESSION_ID" "$INPUT" | \
+curl -sk -X POST "$CODEMAN_API_URL/api/status-telemetry" \
+  -H 'Content-Type: application/json' \
+  -H "X-Codeman-Hook-Secret: $(cat "$CODEMAN_HOOK_SECRET_FILE" 2>/dev/null)" \
+  --data @- 2>/dev/null || echo codeman
+```
+
+⚠️ **`curl -sk`, not `curl -s`.** Prod is loopback **HTTPS with a self-signed cert**; without `-k`, curl returns `000` and the statusline silently shows nothing. `-k` is safe (loopback only). *(The existing hook curls use `-s` without `-k` and have the same latent issue on HTTPS installs — a known, separate follow-up.)*
+
+### 2. Endpoint — `POST /api/status-telemetry` (`status-telemetry-routes.ts`)
+
+Fixed path (sessionId in the **body**, not the URL) so the auth exemption is an exact-match like `/api/hook-event` (`middleware/auth.ts`: loopback-only; `X-Codeman-Hook-Secret`-gated while a tunnel runs). Schema `StatusTelemetrySchema` in `schemas.ts` validates the subset; unknown keys are stripped. Pure parsing/formatting in `usage-telemetry.ts`:
+
+- `parseStatusTelemetry(data)` → `{ fiveHour, sevenDay, … }` or `null`. On change (signature dedup; statusline fires often), store last-known (`plan-usage-latest.ts`) and `broadcast('session:statusTelemetry', { sessionId, …telemetry })`.
+- `parseSessionStatus(data)` + `formatSessionStatusText()` → the **footer** string `Opus 4.8 (1M context)  in:562,411 out:1,188  ctx:56%` (returned as `text/plain`). Available from the first render, even before `rate_limits` appears.
+
+### 3. SSE + frontend chip
+
+`session:statusTelemetry` registered in `sse-events.ts` + `constants.js`. `app.js`:
+- `_onSessionStatusTelemetry` → `updatePlanUsageChip(data)` + save to `localStorage['codeman:planUsage']`.
+- `updatePlanUsageChip` renders two `5h`/`7d` windows; **per-window color by usage** — green `<60%`, yellow `60–84%`, red `≥85%` (`pu-green/pu-yellow/pu-red`); bold labels/values; reset times in the tooltip. `resets_at*1000 → Date`.
+- Chip element ships hidden (`header-plan-usage--hidden`); `applyHeaderVisibilitySettings()` reveals it client-side when the setting is on (response-viewer pattern — **no `renderIndexHtml` strip**, which kept the "title-only" render contract intact).
+
+### 4. Chip data robustness — three layers
+
+1. **Live:** `session:statusTelemetry` SSE on every distinct render.
+2. **Fresh load / reconnect:** server stores the latest in `plan-usage-latest.ts`; `getLightState()` includes it as `planUsage`; the per-connection **init snapshot** replays it; `handleInit` paints the chip immediately (authoritative over localStorage). Null until the first telemetry of the process.
+3. **Offline / cross-restart:** `restorePlanUsageChip()` reads `localStorage` on load (12h freshness guard).
+
+### 5. Injection lifecycle — works for *any* user, never self-destructs
+
+The setting `showPlanUsageLimits` is **synced** (in `settings.json`, not a per-device `displayKey`).
+
+- **On toggle** (`PUT /api/settings`, `system-routes.ts`): reconcile the exporter across **all active Claude sessions' working dirs** — inject on enable, remove on disable. Server-side and authoritative, so existing sessions get the footer + feed the chip *immediately*, no new session needed, no dependency on a client's synced localStorage.
+- **On session create** (`session-routes.ts`): **ADD-ONLY** — inject when `statusLineTelemetry` is true; **never remove**. Sessions in a repo share one `settings.local.json`, so a single create-with-false (e.g. a client whose synced setting hadn't loaded) must not yank the statusLine out from under other live sessions. Removal happens only via the explicit toggle.
+- `applyStatusLineConfig()` is **`isOurs`-guarded** (matches `/api/status-telemetry`), so a user's own hand-authored statusLine is never touched, and it **updates an out-of-date ours-command** so fixes (e.g. `-k`) propagate. **No `CASES_DIR` gate** — runs for linked cases / real repos (where sessions actually run), mirroring `updateCaseModel`.
+
+## Codeman-specific considerations
+
+1. **Account-global limits.** The 5h/7d pools are shared across all sessions on the account → one shared header chip (freshest sample wins), not a per-tab bar.
+2. **The footer is owned, by necessity.** A statusLine command always replaces Claude's default footer. Since `rate_limits` *only* arrives via statusLine, we reconstruct a useful **session-status** footer (model · tokens · ctx %) from the same payload rather than showing the limits there.
+3. **`isOurs`-guarded.** Never removes/overwrites a user's own statusLine on disable; only manages the Codeman exporter.
+4. **Security envelope unchanged.** The exporter runs arbitrary shell every render — same trust model as the hook curls (localhost + `$CODEMAN_HOOK_SECRET_FILE`); reuses the hook-secret gate.
+5. **Claude-only.** OpenCode/Codex emit no `rate_limits` JSON; injection is gated to `mode === 'claude'`.
+6. **Future — auto-resume synergy.** Live percentages would let `SessionAutoOps` pre-arm *before* the wall instead of reacting to the stall footer. Not built.
+
+## Files shipped

+- `src/web/server.ts` — `getLightState().planUsage` (init snapshot).
+- `src/web/sse-events.ts` + `constants.js` — `session:statusTelemetry`.
+- Frontend: `app.js` (`_onSessionStatusTelemetry`, `updatePlanUsageChip`, `restorePlanUsageChip`, `handleInit`), `settings-ui.js` (toggle + `applyHeaderVisibilitySettings`), `index.html` (chip + toggle row), `styles.css` (chip + colors), `session-ui.js` (create payload).
+
+## Bugs E2E testing caught (that unit tests didn't)
+
+The first "shipped" build passed every test and was broken in practice. End-to-end testing on the real install (the lesson: drive a REAL session, observe the REAL output) surfaced:
+
+1. **`CASES_DIR` injection gate** excluded the user's whole workflow — sessions run in linked cases / real repos, not under `~/codeman-cases`. → dropped the gate.
+2. **`curl -s` → `000`** on the loopback self-signed HTTPS cert; statusline silently empty. → `curl -sk`.
+3. **Remove-on-create-false + shared `settings.local.json`** let a single stale client yank the statusLine out from under all sessions in a repo. → add-only on create; removal only via the toggle reconcile.
+4. **Chip blank after reload** (localStorage-only, lost on restart/fresh browser). → server-side last-known in the init snapshot.
+
+## Open questions / future
+
+- **Schema stability.** `rate_limits` is officially shipped but undocumented in exact shape; the parser is tolerant (renders whatever windows exist, ignores unknown).
+- **Hook `curl -s` parity.** Hooks share the no-`-k` issue on HTTPS installs — worth fixing the hook curl too (separate change; covered by `cod54` tests).
+- **Disable cleanliness.** Disabling removes the statusLine from active sessions; a brand-new session created by a *stale* client could re-add it (chip still hidden, footer benign). Fully server-authoritative create-time injection (read the setting server-side instead of the payload flag) would close this — deferred.
+
+## Verification appendix — how the schema was captured (reproducible)
+
+Captured without touching global settings or any real session:
+
+1. Throwaway dir `/tmp/sl-capture` with an exporter `dump.sh` that appends stdin to `payloads.jsonl` and prints `cap`; a `settings.json` pointing `statusLine.command` at it.
+2. `--print` mode does **not** render a statusline → no capture (confirms TUI-only). Must use interactive.
+3. Launch interactive Claude in an **isolated tmux socket** (`tmux -L slcap`, never `-L codeman`) inside the temp dir, `--settings /tmp/sl-capture/settings.json` (no global mutation). Confirm the workspace-trust dialog (appears even with `--dangerously-skip-permissions`), then send a one-line prompt (literal text + Enter separately, Ink-style).
+4. After the first response, `rate_limits` appears in the **second** captured record (absent in the first). Inspect with `jq '.rate_limits'`.
+5. Tear down: `tmux -L slcap kill-server` + `rm -rf /tmp/sl-capture`; verify the `codeman` socket is untouched.
+
+Related: `docs/claude-code-hooks-reference.md` (hook callback pattern), `src/usage-limit-patterns.ts` (reactive fallback), `docs/respawn-state-machine.md` (auto-resume interplay).

+# Versioning & Stability Policy
+
+Codeman follows [Semantic Versioning](https://semver.org/) (`MAJOR.MINOR.PATCH`),
+managed via `@changesets/cli` (see the COM workflow in `CLAUDE.md`).
+
+This document defines **what the version number actually promises** — i.e. which
+surfaces are covered by SemVer and which are explicitly not. It exists because
+"1.0" is a commitment to stability, and an undocumented public surface invites
+incompatible client assumptions we would then be pressured to keep.
+
+> **Status:** finalized for the 1.0 cut. The HTTP/SSE API **is** part of the stable
+> surface — served under `/api/v1` with a uniform response envelope and
+> conventional HTTP status codes. See [`api-reference.md`](api-reference.md).
+
+## What SemVer covers (the public, stable surface)
+
+A **MAJOR** bump is required to break any of these after 1.0:
+
+1. **The CLI.** Command names, documented flags, and their behavior for
+   `codeman <command>` (published to npm as `aicodeman`; invoked as `codeman`).
+   This is the package's actual public entry point (`bin`).
+   - The package is published to npm as `aicodeman` and installs **both** the
+     `aicodeman` and `codeman` commands (`bin` aliases); `codeman` is the
+     canonical command used throughout the docs. Renaming either after 1.0 is a
+     breaking change.
+2. **The published `xterm-zerolag-input` library**, but on **its own version
+   line** — it is versioned and released independently of the Codeman app. Its
+   1.0 status is a separate decision; the Codeman app reaching 1.0 does *not*
+   imply `xterm-zerolag-input` is 1.0.
+3. **Documented environment variables** that configure deployment:
+   `CODEMAN_PASSWORD`, `CODEMAN_USERNAME`, `CODEMAN_HOST`, `CODEMAN_PORT`,
+   `CODEMAN_INSTANCE`, `CODEMAN_ALLOWED_HOSTS`, `CODEMAN_DATA_DIR`,
+   `CODEMAN_TMUX_SOCKET`, and the `--host` / `--port` / `--https` CLI flags.
+   Removing or changing the meaning of one of these is breaking.
+4. **The HTTP API and SSE event channel**, served under **`/api/v1`** with the
+   uniform `{success:true,data}` / `{success:false,error,errorCode}` envelope and
+   conventional HTTP status codes. Endpoint paths, the response envelope, error
+   `errorCode` values, and SSE event names are stable — see
+   [`api-reference.md`](api-reference.md). *Additive* changes (new endpoints, new
+   optional fields, new error codes, new SSE events) are non-breaking; breaking
+   changes ship under a new prefix (`/api/v2`). The unversioned `/api/...` alias
+   is kept working for the bundled UI.
+
+## What SemVer does NOT cover (internal surfaces — may change in any release)
+
+These may change in a **MINOR** (or even PATCH) release without a MAJOR bump:
+
+1. **The `~/.codeman/` state file formats** (`state.json`, `settings.json`,
+   `mux-sessions.json`, etc.). We make a **best-effort** to migrate existing data
+   forward (and have done so across renames), but the on-disk schema is not a
+   stable contract — do not write tooling that depends on its exact shape.
+2. **Internal TypeScript modules.** The npm package is CLI-only; `import`ing it
+   programmatically is not supported (there is no stable library entry point).
+3. **Experimental / opt-in features**, regardless of the app's version:
+   Gesture Control (beta), Agent Teams
+   (`CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`), and anything labeled experimental
+   in the UI or docs. These may change or be removed at any time.
+
+## Deprecation policy
+
+When we need to change a covered surface:
+
+- Prefer **additive** changes (new flag/env var/command) over breaking ones.
+- A covered surface slated for removal is **deprecated first** — it keeps working
+  for at least one MINOR release with a runtime warning and a `CHANGELOG.md` note
+  pointing to the replacement — then removed in the next MAJOR.
+- Back-compat migration shims (e.g. the historical Claudeman→Codeman data/socket
+  migration) are kept until a MAJOR boundary, then may be dropped.
+
+## Pre-1.0 (`0.x`) caveat
+
+Until 1.0 ships, **any release may contain breaking changes** per SemVer's `0.x`
+allowance. The commitments above take effect at `1.0.0`.
+
+## See also
+
+- `CLAUDE.md` — the COM release workflow (changesets, version bump, deploy)
+- `SECURITY.md` — security reporting and the supported-version policy
+- `docs/security-architecture.md` — the full trust model

-- **Tech Stack**: [TECHNOLOGIES_USED]
-- **Last Updated**: [DATE]
 
----
+## Commands
+
+<!-- List the exact commands Claude can't guess — fill in as the project
+     takes shape, then delete this comment:
+
+| Task | Command |
+|------|---------|
+| Dev server | `npm run dev` |
+| Test (single file) | `npm test -- test/<file>.test.ts` |
+| Lint | `npm run lint` |
+| Build | `npm run build` |
+-->
+
+## Code Style
+
+<!-- Only rules that differ from language/framework defaults, one line each:
+- Use 2-space indentation
+- ES modules only — never require()
+-->
+
+## Workflow
+
+- Full permissions are granted: read, write, edit, and execute without asking.
+- Commit after every meaningful change; never batch unrelated work.
+- Use conventional commits (`feat:` `fix:` `docs:` `refactor:` `test:` `chore:`); the message says what changed and why.
+- Run the tests and linter before declaring any task done.
+- Keep README and docs in sync with code changes.
 
 ## Codeman Environment
 
-This session is managed by **Codeman** and runs within a tmux session.
+This session is managed by Codeman and runs inside tmux (`CODEMAN_MUX=1` confirms it).
 
-**Important**: Check for `CODEMAN_MUX=1` environment variable to confirm.
-- Do NOT attempt to kill your own tmux session
-- The session persists across disconnects - your work is safe
-- Token usage, costs, and background tasks are tracked externally
-
----
-
-## Work Principles
-
-### Autonomy
-Full permissions granted. Act decisively without asking - read, write, edit, execute freely.
-
-### Git Discipline
-- **Commit after every meaningful change** - never batch unrelated work
-- Use conventional commits: `feat:`, `fix:`, `docs:`, `refactor:`, `test:`, `chore:`
-- Commit message = what changed + why (not how)
-
-### Documentation
-- Update README.md when adding features or changing setup
-- Update this file's session log after work sessions
-- Keep docs in sync with code changes
-
-### Thinking
-Extended thinking is enabled. Use deep reasoning for complex architectural decisions, difficult bugs, and multi-file changes.
-
-### Task Tracking (TodoWrite)
-**ALWAYS use TodoWrite** to track tasks. This is non-negotiable for anything beyond trivial single-step work.
-
-**When to use TodoWrite:**
-- Multi-step tasks (3+ steps)
-- Bug fixes requiring investigation
-- Feature implementations
-- Any work where progress tracking helps
-- When the user provides multiple requests
-
-**How to use it:**
-1. **Before starting**: Break down the work into discrete todos
-2. **During work**: Mark each todo `in_progress` before starting, `completed` when done
-3. **One at a time**: Only ONE todo should be `in_progress` at any moment
-4. **Immediately**: Mark todos complete the moment they're done - don't batch
-
-**Why this matters:**
-- Gives the user visibility into your progress
-- Prevents forgetting tasks mid-work
-- Creates accountability checkpoints
-- Makes complex work manageable
-
-**Example workflow:**
-```
-User: "Add user authentication with JWT"
-
-→ TodoWrite:
-  - [ ] Research existing auth patterns in codebase
-  - [ ] Implement JWT token generation
-  - [ ] Add login endpoint
-  - [ ] Add token validation middleware
-  - [ ] Add protected route example
-  - [ ] Write tests
-
-→ Mark "Research existing auth patterns" as in_progress
-→ Do the research
-→ Mark as completed, mark next as in_progress
-→ Continue until all done
-```
-
-**Anti-patterns to avoid:**
-- Starting work without creating todos first
-- Having multiple todos `in_progress` simultaneously
-- Batching completions at the end
-- Skipping TodoWrite for "simple" multi-step tasks
-
----
-
-## When to Use Agents
-
-**Explore agent**: Codebase investigation, finding files, understanding architecture
-```
-"Use explore agent to find all authentication-related code"
-```
-
-**Parallel agents**: Independent tasks that don't conflict
-```
-"Research auth, database, and API modules in parallel using separate agents"
-```
-
-**Background execution**: Long-running operations (tests, builds)
-```
-"Run the test suite in the background while I continue"
-```
-
-**Sequential chaining**: When second task depends on first
-```
-"Use code-reviewer to find issues, then use fixer to resolve them"
-```
-
----
-
-## Planning Mode (Automatic)
-
-**Automatically enter planning mode** when ANY of these conditions apply:
-- Multi-file changes (3+ files affected)
-- Architectural decisions
-- Unclear or evolving requirements
-- Risk mitigation on core systems
-- New feature implementation
-- Refactoring existing functionality
-
-**Do NOT ask** whether to enter planning mode - just enter it when conditions are met.
-
-Planning mode flow: read-only exploration → create plan → get approval → execute.
-
-**Skip planning mode** only for:
-- Single-file bug fixes
-- Typo corrections
-- Simple config changes
-- Tasks with explicit step-by-step instructions from user
-
----
-
-## Ralph Wiggum Loop (Autonomous Work Mode)
-
-Ralph loops enable persistent, autonomous work on large tasks. When active, you continue iterating until completion criteria are met or the loop is cancelled.
-
-### Starting a Ralph Loop
-- Start: `/ralph-loop:ralph-loop`
-- Cancel: `/ralph-loop:cancel-ralph`
-- Help: `/ralph-loop:help`
-
-### Time-Aware Loops
-
-When the user specifies a **minimum duration** (e.g., "optimize for 8 hours", "work on this for 2 hours"), the loop becomes time-aware:
-
-**At loop start:**
-```bash
-# Record start time
-date +%s > /tmp/ralph_start_time
-echo "Loop started at $(date)"
-```
-
-**Check elapsed time periodically:**
-```bash
-START=$(cat /tmp/ralph_start_time)
-NOW=$(date +%s)
-ELAPSED_HOURS=$(echo "scale=2; ($NOW - $START) / 3600" | bc)
-echo "Elapsed: $ELAPSED_HOURS hours"
-```
-
-**Time-aware behavior:**
-1. Complete all primary tasks from the user's prompt
-2. After primary tasks done, check elapsed time
-3. If minimum duration NOT reached:
-   - **Do NOT output completion phrase**
-   - Self-generate additional related tasks
-   - Continue working until minimum time elapsed
-4. Only output completion phrase when:
-   - ALL primary tasks complete AND
-   - Minimum duration reached (or exceeded)
-
-**Self-generating additional tasks when time remains:**
-- Code optimization (performance, readability, DRY)
-- Test coverage improvements
-- Edge case handling
-- Error message improvements
-- Documentation gaps
-- Security hardening
-- Accessibility improvements
-- Code cleanup and dead code removal
-- Dependency updates
-- Type safety improvements
-
-**Example time-aware prompt:**
-```
-"Optimize the API endpoints for the next 4 hours. Focus on performance first,
-then code quality. Minimum runtime: 4 hours."
-Completion phrase: <promise>TIME_COMPLETE</promise>
-```
-
-**Time-aware loop behavior:**
-```
-[Start loop, record timestamp]
-[Complete primary optimization tasks - 2 hours elapsed]
-[Check time: 2/4 hours - NOT done yet]
-[Self-generate: "Add caching to database queries"]
-[Self-generate: "Optimize N+1 queries"]
-[Self-generate: "Add request batching"]
-[Continue working... 4.5 hours elapsed]
-[Check time: 4.5/4 hours - minimum reached]
-[All tasks complete, tests pass]
-<promise>TIME_COMPLETE</promise>
-```
-
-### How You Know You're in a Ralph Loop
-
-The user started the loop with a prompt containing:
-- Clear task requirements
-- A **completion phrase** (e.g., `<promise>COMPLETE</promise>`)
-- **Optional: minimum duration** (e.g., "for the next 4 hours")
-- Iteration limits (handled by the system)
-
-Your job: Keep working until ALL requirements are verifiably done AND minimum time reached (if specified), then output the exact completion phrase.
-
-### Core Behaviors During Ralph Loop
-
-**1. Work Incrementally**
-- Complete one sub-task at a time
-- Verify it works before moving to the next
-- Don't try to do everything in one pass
-
-**2. Commit Frequently**
-- Commit after each meaningful completion
-- Creates recovery points if something breaks
-- Shows progress in git history
-```
-git add . && git commit -m "feat(auth): add token refresh endpoint"
-```
-
-**3. Self-Correct Relentlessly**
-```
-Loop:
-  1. Implement/fix
-  2. Run tests
-  3. If tests fail → read error, fix, go to 1
-  4. Run linter
-  5. If lint errors → fix, go to 1
-  6. Commit
-  7. Continue to next task
-```
-
-**4. Track Progress**
-Update the session log in this file as you complete tasks:
-```markdown
-| Date | Tasks Completed | Files Changed | Notes |
-|------|-----------------|---------------|-------|
-| YYYY-MM-DD | Add auth endpoint | auth.ts, routes.ts | Tests passing |
-```
-
-**5. Use Git History When Stuck**
-If something isn't working:
-```bash
-git log --oneline -10
-git diff HEAD~1
-```
-See what you already tried. Don't repeat failed approaches.
-
-**6. Completion Phrase = Contract**
-Only output the completion phrase (e.g., `<promise>COMPLETE</promise>`) when:
-- ALL requirements from the original prompt are done
-- ALL tests pass
-- ALL linting passes
-- Changes are committed
-
-**Never output the completion phrase early.** The loop only ends when you say it's done.
-
-### What Makes Good Completion Criteria
-
-The user should provide criteria that are:
-- **Verifiable**: Tests pass, lint clean, build succeeds
-- **Measurable**: "5 endpoints", "all files in src/", "zero errors"
-- **Binary**: Done or not done, no ambiguity
-
-If the original prompt has vague criteria, ask clarifying questions before starting heavy work.
-
-### Self-Correction Pattern (Include in Your Work)
-
-```
-FOR EACH TASK:
-1. Implement the change
-2. Run tests (npm test, pytest, go test, cargo test, etc.)
-   - If fail → read error, fix, retry
-3. Run linter (npm run lint, ruff, golangci-lint, etc.)
-   - If fail → fix, go to step 2
-4. Verify manually if needed
-5. Commit with descriptive message
-6. Update session log
-7. Move to next task
-
-WHEN ALL TASKS DONE:
-1. Run full test suite
-2. Run full lint
-3. Verify build succeeds
-4. Review all changes: git diff main
-5. Only then output completion phrase
-```
-
-### Example: How to Think During Ralph Loop
-
-**Original prompt**: "Add CRUD endpoints for todos with validation"
-
-**Your approach**:
-```
-Task breakdown:
-- [ ] GET /todos (list)
-- [ ] POST /todos (create with validation)
-- [ ] GET /todos/:id (single)
-- [ ] PUT /todos/:id (update with validation)
-- [ ] DELETE /todos/:id
-- [ ] Tests for all endpoints
-
-Starting with GET /todos...
-[implement]
-[test - passes]
-[commit: "feat(todos): add GET /todos endpoint"]
-[update session log]
-
-Moving to POST /todos...
-[implement]
-[test - fails: validation not working]
-[fix validation]
-[test - passes]
-[commit: "feat(todos): add POST /todos with validation"]
-[update session log]
-
-...continue until all done...
-
-Final verification:
-[npm test - all pass]
-[npm run lint - clean]
-[npm run build - succeeds]
-
-<promise>COMPLETE</promise>
-```
-
-### When to NOT Output Completion Phrase
-
-- Tests are failing (even one)
-- Lint errors exist
-- Build is broken
-- You skipped a requirement
-- You're unsure if something works
-- **Minimum duration not reached** (for time-aware loops)
-
-Instead: Fix the issue, verify, then complete. For time-aware loops: generate more tasks and keep improving until minimum time elapsed.
-
-### RALPH_STATUS Block (Required During Ralph Loop)
-
-At the **END of every response** during a Ralph Loop, output this structured status block:
-
-```
----RALPH_STATUS---
-STATUS: IN_PROGRESS | COMPLETE | BLOCKED
-TASKS_COMPLETED_THIS_LOOP: <number>
-FILES_MODIFIED: <number>
-TESTS_STATUS: PASSING | FAILING | NOT_RUN
-WORK_TYPE: IMPLEMENTATION | TESTING | DOCUMENTATION | REFACTORING
-EXIT_SIGNAL: false | true
-RECOMMENDATION: <one line summary of what to do next>
----END_RALPH_STATUS---
-```
-
-**Rules:**
-- Output this block at the end of **every** response, no exceptions
-- Set `EXIT_SIGNAL` to `true` ONLY when ALL tasks are verifiably done
-- Set `STATUS` to `BLOCKED` when you need human intervention
-- Do NOT continue with busy work when `EXIT_SIGNAL` should be `true`
-- Do NOT forget the status block — it is required for loop tracking
-
-### Testing Limits
-
-- **LIMIT testing to ~20% of total effort** per loop
-- PRIORITIZE: Implementation > Documentation > Tests
-- Only write tests for NEW functionality
-- Do NOT refactor existing tests unless broken
-- Do NOT run tests repeatedly without implementing new features
-
-### Exit Scenarios (When to Set EXIT_SIGNAL)
-
-| Scenario | STATUS | EXIT_SIGNAL | Action |
-|----------|--------|-------------|--------|
-| All tasks completed, tests pass | COMPLETE | true | Output completion phrase |
-| No work remaining, specs done | COMPLETE | true | Output completion phrase |
-| Making normal progress | IN_PROGRESS | false | Continue to next task |
-| Test-only loop (no implementation) | IN_PROGRESS | false | Warn and shift to implementation |
-| Stuck on same error repeatedly | BLOCKED | false | Describe blocker, request help |
-| Needs human decision/intervention | BLOCKED | false | Describe what's needed |
-
-**Anti-patterns to avoid:**
-- Setting `EXIT_SIGNAL: true` when tests are failing
-- Continuing to work when all tasks are genuinely done (busy work)
-- Running the same failing test repeatedly without changing approach
-- Adding features not in the original specifications
-- Refactoring working code instead of completing assigned tasks
-
----
-
-## Code Standards
-
-### Before Writing
-- Read existing code in the area you're modifying
-- Follow existing patterns and conventions
-- Check for similar implementations to reference
-
-### During Implementation
-- Keep changes focused and minimal
-- Don't over-engineer
-- Write tests for new functionality
-
-### After Implementation
-- Run tests
-- Update docs if needed
-- Commit with descriptive message
-
----
-
-## Hooks Awareness
-
-This project may have hooks that auto-format code after writes or validate operations. If a tool call behaves unexpectedly, hooks are likely the cause. Continue working - they're intentional.

+- NEVER kill your own session: no `tmux kill-session`, `pkill tmux`, or `pkill claude`.
+- The session persists across disconnects — your work is safe.
+- Hooks may auto-format or validate after writes; unexpected tool behavior usually means a hook ran. Keep working.

+ * (ANSI-stripped) terminal output and parse the reset time, so the session
+ * auto-resume feature (SessionAutoOps) can schedule a "continue" nudge.

+ * - `5-hour limit reached ∙ resets 8pm`                                (v1.0.109+ footer)
+ * - `Session limit reached ∙ resets 8pm`
+ * - `Weekly limit reached ∙ resets 6pm`
+ * - `Opus weekly limit reached ∙ resets Oct 6, 1pm`
+ * - `Limit reached · resets 1pm (America/Chicago) · /upgrade to Max…`  (v2.0.55+)
+ * - `You've hit your limit · resets 1:40pm (America/New_York)`         (v2.1.x)

+ * - `Claude AI usage limit reached|1755309600`                         (raw API, epoch seconds)

+ * @fileoverview Allowlist-based HTML sanitizer for markdown-rendered, agent/transcript-derived
+ * content that is subsequently assigned via innerHTML (response viewer, attachment markdown
+ * preview, message bodies).
+ *
+ * Security (COD-56): the previous sanitizer was a hand-rolled DENYLIST — it removed a fixed
+ * set of tags (script/iframe/object/embed/form/base/meta/link/style), stripped on* attrs and a
+ * few dangerous URL schemes, then re-serialized. Denylists are mXSS-prone: they did not strip
+ * `svg`/`math` (which carry their own foreign-namespace parsing rules and can smuggle script via
+ * namespace confusion), did not strip `style` attributes (CSS `expression()`/`url(javascript:)`
+ * on legacy engines), and had no positive allowlist, so any tag/attribute not explicitly named
+ * survived. `marked` runs with raw-HTML passthrough, so crafted HTML echoed by an agent flows
+ * straight into this function.
+ *
+ * This module replaces that with DOMPurify (Cure53), an allowlist sanitizer that is the
+ * industry standard for mXSS defense. It is configured to allow exactly the tag/attribute set
+ * that markdown rendering legitimately produces (headings, lists, code, blockquotes, links,
+ * tables, images with safe src) and to FORBID `style`/`svg`/`math` plus all event handlers and
+ * dangerous URL schemes.
+ *
+ * Cross-environment: in the browser this file runs as a classic <script> after
+ * vendor/dompurify.min.js and wires `window.sanitizeMarkdownHtml`. The factory is also exported
+ * (window/globalThis + CommonJS) so a jsdom unit test can build a sanitizer bound to a
+ * jsdom-window DOMPurify instance and exercise the exact same config.

+/**
+ * @fileoverview Ultracode floating run windows — auto-popping draggable windows
+ * 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.
+ *
+ * @mixin Extends CodemanApp.prototype via Object.assign
+ * @dependency subagent-windows.js (makeWindowDraggable, updateConnectionLines, #connectionLines)
+ * @dependency ultracode-panel.js (workflowRuns/workflowRunDetails, _workflowAgentCardHtml, _fmtNum)
+ * @loadorder 15.5 (after subagent-windows.js — needs makeWindowDraggable at runtime)
