 | `lib/webhooks.js`         | Universal webhook delivery engine driven by the provider registry. `buildRequest()` resolves the URL, formats the provider-native payload, and assembles headers (provider auth headers + generic-family custom headers + optional HMAC-SHA256 signature via `X-Webhook-Signature` / `X-Webhook-Timestamp`). `dispatchAlert()` fans a fired alert out to every enabled, in-scope target (optional per-rule scoping via `rule_ids`); each `deliver()` POSTs with an `AbortController` timeout and bounded retry/backoff (retries transport errors / 429 / 5xx, never other 4xx) and records the attempt-chain outcome in `webhook_deliveries` (pruned to the newest 2000 rows). Delivery is detached and fully fail-safe — it never throws into the alert path. Enabled targets are cached like alert rules; tunables (`WEBHOOK_TIMEOUT_MS`, `WEBHOOK_MAX_ATTEMPTS`, `WEBHOOK_RETRY_BASE_MS`) are env-overridable. `sendTest()` awaits a synthetic delivery for the test endpoint |
 | `routes/workflows.js`     | Aggregate workflow visualization data (agent orchestration graphs, tool transition flows, collaboration networks, workflow pattern detection, model delegation, error propagation, concurrency timelines, session complexity metrics, compaction impact). Accepts `?status=active\|completed` query parameter to filter all data by session status and `?sections=a,b` to compute only those parts. The `GET /` bundle itself lives in `lib/workflow-stats.js` and runs in the read worker (`lib/read-pool.js`). `GET /api/workflows/skill-usage` reports per-skill and per-plugin call counts, counting `PreToolUse` rows only so a call is not double-counted against its `PostToolUse` twin. Per-session drill-in endpoint with agent tree, tool timeline, and event details |
 | `lib/workflow-stats.js`  | The eleven `GET /api/workflows` aggregations as pure reads over a passed-in connection (`computeWorkflowData(conn, status, sections)`), so they run in the read worker. `stats.topFlow` is the head of `toolFlow.transitions`: tool pairs come from one `LEAD() OVER (PARTITION BY session_id ORDER BY id)` pass — never a correlated `MIN(id) … id > ?` per event, which is quadratic in a session's size |
-| `lib/read-pool.js`        | Heavy read-only jobs off the event loop: one worker thread with its own `query_only` connection (same driver order as `db.js`), identical in-flight calls shared, a job past `AGENTHUB_READ_TIMEOUT_MS` (60 s) refused `EREADTIMEOUT` and its worker replaced, inline when `AGENTHUB_READ_WORKER=0` or a worker cannot start.

+| `lib/read-pool.js`        | Heavy read-only jobs off the event loop: one worker thread with its own `query_only` connection (same driver order as `db.js`), identical in-flight calls shared, a caller's `maxAgeMs` reusing a result that young (`/api/workflows` 30 s, `/api/analytics`'s events scans 10 s — args are the key, so a member's scoped result is never shared), a job past `AGENTHUB_READ_TIMEOUT_MS` (60 s) refused `EREADTIMEOUT` and its worker replaced, inline when `AGENTHUB_READ_WORKER=0` or a worker cannot start. Add a job to `JOBS` to move another aggregate there. The server's WAL checkpoint (`walCheckpoint`, every `DASHBOARD_WAL_CHECKPOINT_MS`, default 5 s) also runs here, on a second writable connection of the worker: the main connection sets `wal_autocheckpoint = 0`, so no hook's `COMMIT` pays for a checkpoint; a failed checkpoint turns the automatic one back on |
 | `lib/transcript-cache.js` | Stat-based JSONL transcript cache with incremental byte-offset reads. Shared between `hooks.js` (token extraction on every event) and the periodic compaction scanner (`index.js`). Extracts tokens, compaction entries, API errors (`isApiErrorMessage` + raw error responses), turn durations (`system` subtype `turn_duration`), thinking block counts, usage extras (service_tier, speed, inference_geo), user-interrupt markers (the transcript `[Request interrupted by user]` entry / `interruptedMessageId` field — surfaced as `pendingInterrupt`, computed from transcript ordering: latest interrupt vs latest real turn activity, both on Claude Code's clock), and the latest session title — `custom-title` (`/rename`, `claude -n`, picker Ctrl+R) and `ai-title` (auto / plan-accept), append-only so the last value wins, carried through both full and incremental reads — plus the session's **first user prompt** (`firstUserMessage`: tool-result, meta/caveat, slash-command plumbing, compact-summary, and interrupt entries skipped; whitespace-collapsed, capped at 500 chars; first value wins across incremental reads), used as a fallback descriptor for placeholder-named sessions/agents. Uses `(path, mtime, size)` cache key — unchanged files return cached results instantly, grown files only parse new bytes, shrunk files (compaction) trigger full re-read. Each cache entry stores **only** `{mtimeMs, size, bytesRead, result}` — the previous shape that duplicated every growable array at both the top level and inside `result` is gone, halving steady-state memory per entry. Per-entry growable arrays (`turnDurations`, `errors`, `compaction.entries`, `usageExtras.*`) are bounded to `TRANSCRIPT_CACHE_MAX_ARRAY_LEN` (default `1000`, tail-kept) — older items remain in the `events` table thanks to hook dedup, so the cap only affects the in-memory view. Trimming runs both during parse (when an array reaches `2 * MAX_ARRAY_LEN`, amortized O(N)) and at finalize, so even a fresh full-file parse on a multi-day session cannot accumulate an unbounded transient before returning. **Chunked sync byte-stream reader** (`_streamRange`, 4 MiB chunks split on `0x0A` bytes — safe across UTF-8 multibyte sequences — with a growable per-line byte buffer capped at 64 MiB) replaces the previous `readFileSync("utf8")` so transcripts larger than V8's max JS string length (~512 MiB on 64-bit Node 20) parse without aborting Node with `FATAL ERROR: v8::ToLocalChecked Empty MaybeLocal`. Both full and incremental reads share the same line-level state machine (`_initParseState` / `_consumeLine` / `_finalizeState`). LRU eviction caps at 200 entries. Entries evicted on SessionEnd and abandoned session cleanup |
 | `lib/session-liveness.js` | Process-liveness probe for the watchdog's dead-session reap. `probeLiveCwds()` enumerates running `claude` CLI processes (`ps -Ao pid=,args=`, then `lsof -a -p <pids> -d cwd -Fn` on macOS or `/proc/<pid>/cwd` on Linux) and returns the set of their working directories; `isClaudeCommand()` matches the bare binary and `node`/`bun`-launched shims while rejecting lookalikes (`claude-mem`, `Claude.app`). Fail-safe by contract: returns `available: false` (callers must change nothing) on Windows, inside containers (reuses `isInsideContainer` from `scripts/install-hooks.js` — host processes are invisible there, so an empty list would lie), on `ps`/`lsof` failure, or when `DASHBOARD_LIVENESS_PROBE=0` |
 | `bin/agenthub.js` | Dependency-free umbrella CLI (`agenthub <command>`) exposing the full dashboard surface in the terminal: monitoring (health / stats / kanban / tail via short-interval event polling), data browsing (sessions, per-session detail with an indented agent tree + cost + recent events, agents, events), insights (analytics, workflow intelligence, dynamic Workflow-tool runs, per-model cost), alerts + rules + webhook test probes, pricing CRUD, imports (rescan / scan-path), and administration (doctor, info, export, cleanup, reinstall-hooks, clear-data). Linked globally by `npm run setup` via a fail-soft `npm link` (`link-cli` script). Discovers the live server through `server/lib/server-info.js` (`~/.claude/.agenthub.json`, PID-liveness-checked) with `CLAUDE_DASHBOARD_PORT` / `DASHBOARD_PORT` env overrides and a 4820 fallback; renders a full terminal UI — box-drawn width-fitted tables with right-aligned numeric columns, status icons, inline bar charts (stats / analytics / cost), `├─`/`└─` agent trees, and a TTY spinner for `start` — whose ANSI styling degrades to plain text when piped (`--no-color` / `NO_COLOR` / `FORCE_COLOR` / `AGENTHUB_COLOR` respected); the one destructive command (`clear-data`) refuses to run without `--yes`. Server lifecycle: `agenthub status` shows a ●/○ up/down indicator and `agenthub start` boots a detached production server (waits for /api/health, logs to `data/agenthub-server.log`). `agenthub repl` (aliases `shell` / `i`) opens an interactive shell — a readline prompt with tab-completion (commands / subcommands / flags), persisted arrow-key history (`data/.agenthub_repl_history`), and a live server-status prompt; each entered line runs as a short-lived child `agenthub` process (via `runCommand` dispatch), so an offline refusal or a blocking `tail` cannot take the shell down, and piped input runs each line in order then exits at EOF. When the server is down, read-only commands (sessions / session / agents / events / kanban / stats / pricing list / alerts list / rules / export / doctor) fall back to direct SQLite reads of `data/dashboard.db` under a ⚠ Offline-mode banner — the connection is opened without SQLite readonly mode so a live WAL stays visible, and is SELECT-only by construction — while server-only commands (tail, analytics, workflows, runs, cost, mutations) refuse with the specific reason |

 | `lib/tmux.js`             | Wrapper around tmux CLI for session management. `createSession(sessionName, cwd)` creates a new tmux session in the specified working directory. `sendCommand(sessionName, command)` sends a command into the session. `killSession(sessionName)` terminates the session. `listSessions()` returns all active sessions. Session management is the foundation for the PTY transport layer |
 | `lib/pty-run.js`          | PTY lifecycle for tmux-backed runs. Manages one tmux session per lane, named `agenthub-lane-<lane.id>`. Exports `startRun()` to create/attach a session and return a `runId` opaque handle; internally uses tmux to manage the pseudoterminal. Spawned `claude` processes run inside the session and fire the dashboard's hooks like any other CLI session, so they show up in `/api/sessions`, the analytics, the Kanban board, and the Workflows page automatically. The PTY frames (terminal input/output deltas) are streamed to the client over `/ws-pty/:runId` (see `server/websocket.js`) at binary frame granularity rather than as JSON envelopes; the client's xterm.js terminal widget renders these raw PTY updates live. Every spawn also mirrors itself into `dashboard_runs` (cwd, model, prompt preview, `resume_session_id`, lane id, start time) — that row is the ONLY source `publicRun` has for those fields, since the handle itself is recomputed from tmux on every read, so a dropped insert renders as a live run with no cwd, model or start date. `mode` is NOT NULL in that table and `recordRun` swallows insert errors by design, which is why this module passes a literal `"interactive"` rather than null. **Create-or-adopt has one refusal:** a pane already running an agent is adopted silently only when the request asked for nothing but a pane — a `resumeSessionId` or an initial prompt cannot be typed over a live agent, so it throws `ERUNLIVE` (409) rather than reporting a resume that never spawned |
 | `lib/pty-attach.js`       | Client-side PTY attachment via WebSocket. Establishes a `/ws-pty/:runId` connection, receives binary PTY frames, and feeds them to an xterm.js terminal instance. Handles reconnection, resize events (sending `TIOCSWINSZ` ioctl to the tmux pane), and cleanup on disconnect. A single tmux session can have many simultaneous PTY clients (browser Workspace, `agenthub lanes shell` CLI, etc.), all synced live The server side (`server/lib/pty-attach.js`) runs `tmux attach` with the LIVE tmux server's own binary (`/proc/<tmux.serverPid()>/exe`, else `tmux` on PATH): a tmux upgraded while its server runs leaves a newer client on PATH that the old server refuses with `open terminal failed: not a terminal`. |

Reset and managed removal call the worktree's independent managed-kind, realpath-within-`LANES_ROOT`, and listed-worktree guard; adopted reset is refused, while adopted remove only forgets its row and never modifies its directory, and a managed lane whose directory was deleted by hand takes a prune path that still enforces the managed-kind and inside-`LANES_ROOT` checks. `start` returns `409 ERUNLIVE` rather than overwriting a live `run_id` and orphaning its child. `kind`, `source_repo`, `slug`, `base_branch`, `slot` and `ports` are not patchable — provisioning writes them through `lanesLib.setProvisioningFacts`.

 | `lib/lane-slots.js`       | Slot and port allocation — the numbering Shipyard gets free from fixed `lane1..lane9` directories and AgentHub, keyed by `cwd`, must allocate. `allocateSlot` takes the lowest free of `LANE_MAX_SLOTS` (default 9) under the per-lane lock, with a partial unique index on `lanes.slot` as the backstop; allocation is **lazy**, so a lane that is only watched never consumes one. `releaseSlot` runs on remove but never on reset (moving a lane's ports mid-feature is a silent failure, not a fresh start). `resolvePorts` prefers `PORT_BASE_<name> + slot`, then steps `+100` at a time so the last digit still reads as the slot, skipping anything listening, recorded by another lane, or already taken in the same boot. `slotDirs` puts run/log state under `LANES_ROOT/.state/lane<slot>/` — outside the worktree, because `reset`'s `git clean -fd` would otherwise sweep live pid files. `dbName`/`dataFacts` (A2) derive the same kind of slot-based fact one layer up: database name, `DATABASE_URL`/`TEST_DATABASE_URL`, a Redis logical index, and the upload directory — each `null` when its owning profile declaration (`DB_PREFIX`, `REDIS`, `UPLOAD_SUBDIR`) is absent |
 | `lib/lane-profile.js`     | The stack seam. Resolves `<repo>/.agenthub/profile/` from the lane's own working copy first (a branch that edits its boot command must boot with it), the source repo second. `profile.env` is **parsed, not sourced** — `$(…)` stays literal, because sourcing repo shell into the dashboard process would be a code-execution path. `runHook` spawns `bash <hook>` with an argv array through a wrapper that `export -f`s `harness_spawn`/`die`, exports Shipyard's env contract verbatim (`LANE` is the **slot**, plus `<NAME>_PORT` per declared port, plus A2's `DB_NAME`/`DATABASE_URL`/`TEST_DATABASE_URL`/`PG_HOST`/`PG_PORT`/`PG_USER`/`REDIS_URL`/`REDIS_HOST`/`REDIS_PORT`/`UPLOAD_DIR` when their profile declaration is present) so its profiles port unchanged, scrubs `GIT_*` exactly as `worktree.js:git()` does, redacts any `secrets.js` password from its output before it reaches the log file or the `lane_hook_output` broadcast, and streams the rest to both `$LOG_DIR/<hook>.log` and that broadcast.

 ### Splash & loading UX
 
 - **`SplashScreen.tsx`** — rendered by `App.tsx` as a fixed full-screen overlay alongside the router. Shows once per browser session (`sessionStorage` gate, read synchronously so a repeat mount never flashes). Time-aware greeting + localized tagline/subtexts (`splash` i18n namespace, en/zh/vi/ko) + an animated node-graph brand mark on a dark backdrop (radial glow, drifting constellation, grain). The backdrop is **opaque from the first paint** (no entrance fade on the root) so the app rendered behind it never flashes through; only the inner content cascades in. Holds ~2.5 s, then fades out and unmounts; click-to-skip; honors `prefers-reduced-motion`. CSS-only keyframes, no added dependencies.
-- **Colour tokens (`client/src/index.css`, `tailwind.config.js`)** — one CSS-variable set per mode, plus named-theme override blocks keyed by `data-theme` on `<html>` (Darcula, Apple Dark, Apple Light, IntelliJ Light, Canvas — picked in Settings → Appearance, `components/settings/AppearanceSettings.tsx`, state in `hooks/useTheme.ts`), consumed as `bg-surface-N` / `text-fg-*` / `border-border*` / `text-status-*` / `text-syntax-*`. The surface ramp encodes ELEVATION and rises in lightness with its index in BOTH themes: light mode's page is `surface-0` `#e8e5da` and a `.card` is the brighter `surface-3` `#f5f3ec` (Claude's warm ivory family rather than Radix slate — a cool near-white page reads as glare at any lightness, while dark mode stays slate + blue), so hovers lift instead of dimming. (Light mode previously used Radix slate in its native direction — index up meant darker — which put a near-white page under grey, recessed-looking cards: the "glaring and muddy at once" report.) Light `--accent` is `#924224` — Claude's terracotta three steps down, since the brand `#cc785c` is 3.1:1 on ivory — not dark's blue; `--accent` is a TEXT colour (dark Default `#70b8ff`), so white text sits on `--accent-solid` (`bg-accent-solid`, `.btn-primary`, Switch, Checkbox — dark Default `#0076d1`, light = `--accent`), never on `--accent`; `--fg-muted` is held at ≥4.5:1 because it carries timestamps and counts; `--shadow-card`, not the deliberately quiet `--border`, carries "raised" in light mode. Syntax colouring is tokenised too (`--syn-*`), dark keeping its 300-level pastels and light taking the same hues four steps darker. A hardcoded near-black panel, a `hover:text-white`, or `filter: invert(1)` on a form glyph is by definition a light-mode bug — token it, or scope it under `.dark`. Status and accent **fills** are pre-mixed rather than translucent: `tint()` in `tailwind.config.js` compiles `bg-status-success/10` and `border-status-danger/40` to `color-mix(…, rgb(var(--tint-base)))`, because an alpha tint composites with what is behind it and made one chip render as five different colours over the five surface steps. It is deliberately scoped to `backgroundColor`/`borderColor` — `text-*/NN` and `ring-*/NN` must stay translucent, and a translucent `surface` is what every scrim is made of.

 - **`Tooltip.tsx` (`GlobalTooltip`)** — mounted once by `App.tsx` beside the router. Every control in the app keeps writing the native `title="…"`; this listener upgrades it in place — on a 350 ms hover rest or immediately on keyboard focus it parks the attribute in `data-tip`, renders an anchored bubble (portal, arrow, flip above/below, viewport clamp, theme tokens so light mode is legible), and restores the attribute when it closes on pointer-out / pointer-down / scroll / resize / `Escape`. No wrapper at the call site, nothing to remember for the next `title=`, and the native tooltip plus the control's accessible name survive with JS off. `data-tip-off` opts an element out; `Tip.tsx` (cursor-following, for expanding a truncated number mid-sentence) draws the same `TOOLTIP_SURFACE`.
 - **Loading skeletons** — the shared `Skeleton` primitive (`components/Skeleton.tsx`) uses Tailwind `animate-pulse`. `Analytics.tsx` now renders a pulsing `AnalyticsChartsSkeleton` for the whole chart region while `data` is null (previously it fell back to empty/zero charts).
 - **`Workflows.tsx` `Section`** — the right-aligned section subtitle is clamped to a single line (`truncate` + `max-w` + hover `title`) so a long translation never wraps and unbalances the header; the full text stays in the section's `i` popover.

Runs every git call via `execFile` (no shell, 10s–120s timeouts) and reads the newest release over `fetch` with an `AbortSignal.timeout` — `fetchLatestRelease` NEVER throws, resolving to `{ok:false, reason}` (`no_remote`, `remote_not_http`, `no_releases`, `unreachable`, `bad_payload`, `http_<status>`) so a status poll degrades instead of erroring. `releaseApiUrl` derives the endpoint from a repository URL (https, scp-style and `ssh://` forms) and returns null for anything not owner/repo shaped, which is what keeps local-path remotes off the network entirely. `fetchLatestRelease` finds that URL via the `origin` remote; `fetchReleaseFromUrl` takes one directly, which is how the **git-free plugin path** works: `pluginMarketplaceUrl(mkt, plugin)` reads `known_marketplaces.json` → the marketplace's `.claude-plugin/marketplace.json` → the entry's `source.url`, returning null (never a guessed host) for a `github` `owner/repo` shorthand and never throwing. **Order matters:** `detectPluginInstall` runs FIRST in `getUpdatesStatus`, ahead of the `.git` probe — a plugin cache unpacked from an archive has no `.git`, and probing first is the 1.5.1 bug that made `update_available` permanently false. `compareVersions` orders numeric triples and strips a leading `v`, since this repo carries both `v1.5.0` and `1.4.6`. `isShallowClone` gates every commit-distance calculation; `detectPluginInstall` reads the marketplace and plugin name out of the cache path. **Branch- and fork-aware** as before: resolves `<remote>/master`/`/main`/`/HEAD`, reads the current branch and its tracked upstream, and shapes `manual_command` per situation — the `claude plugin ...` commands for `plugin_managed`; `git fetch <remote> --tags && git merge --ff-only <tag>` for `release_available`; `git pull --ff-only` when the branch tracks the canonical ref; `git fetch <remote> && git merge --ff-only <ref>` for forks; `git fetch <remote>` only on a feature branch or detached HEAD. Non-git installs, missing remotes, fetch failures, and unresolvable upstream refs are returned as soft payloads — never throws. |
 | **`server/update-scheduler.js`** | Ticks the lib every `DASHBOARD_UPDATE_CHECK_INTERVAL_MS` (default 300 000, floor 60 000). First tick is scheduled 8s after server start with `.unref()` so it doesn't block shutdown. Broadcasts only when the fingerprint `{update_available, remote_sha, commits_behind, fetch_error, manual_command}` changes — `manual_command` is included so situation transitions (e.g. user switches branches, or adds an `upstream` remote) trigger a re-broadcast even when the SHA and commit count are unchanged. Emits a framed message to stdout on "up-to-date → behind" transitions, and only suggests "restart the dashboard" when the printed command actually rewrites the working tree. `DASHBOARD_UPDATE_CHECK=0\|false\|off` disables the scheduler entirely. |

 | **`server/lib/plugin-update.js`** + **`scripts/plugin-update-helper.js`** | The plugin-cache update chain. The lib only spawns the helper detached (cwd = the runtime dir, **not** the plugin root, which is about to be superseded) and clears any previous verdict first so a stale success can't be read back as this run's result. All work is in the helper because its last step SIGTERMs the server that asked for the update — the same split as `self-restart.js`, one step further. The helper re-validates the marketplace and plugin names against `/^[A-Za-z0-9][\w.-]*$/` (they reach an argv across a process boundary), resolves `claude` on PATH or at `~/.local/bin/claude` (a hook-spawned server does not inherit the login shell's PATH), picks the newest cache directory that isn't the old root and does contain `scripts/plugin-bootstrap.js`, and records **every** outcome — including an unexpected throw — to `plugin-update.json` under `~/.claude/agenthub/runtime/`, outside the cache so it survives the swap. Steps: `validate`, `resolve_claude`, `marketplace_update`, `plugin_update`, `already_current` (`ok:true`; nothing was pulled and the old server was left running), `bootstrap`, `done`. `readLastPluginUpdate()` surfaces it as `last_plugin_update` on the status payload — without it a failed chain is indistinguishable from a slow one. |
 | **`UpdateNotifier.tsx`** | Modal. Hydrates from `api.updates.status()` on mount and mirrors the payload back into the local `eventBus` so the Sidebar can listen without a second git fetch. Subscribes to `update_status` WS frames for ongoing sync. Keeps the dismissal key in `localStorage` (`agent-monitor-update-dismissed-sha`) and in React state — the **release tag** when one was read, else the upstream SHA, so a newer release re-opens the prompt while a dismissed one stays dismissed; a window event `dashboard:reset-update-dismissal` from the Sidebar clears both. ESC / backdrop click dismisses. |
 | **`Sidebar.tsx`** | The update state and its **Check for updates** button live in the connection details modal the sidebar owns (opened from the status bar; the sidebar has no footer); the status bar shows a green dot beside the version while a release is out. Subscribes to `update_status` (no own fetch). On click: clears dismissed SHA in localStorage, dispatches `dashboard:reset-update-dismissal`, then calls `api.updates.check()`. Visual state: emerald badge when `update_available`, amber when `fetch_error`, neutral otherwise. Label has four resting states, not two — `"<tag> available"`, `"Dev build · N ahead"` (when `dev_build`), `"Up to date"`, or `"Check for updates"` before the first result. |

The modal notes that an already-open Claude Code session still needs `/reload-plugins` for new skills/commands. |
-| Plugin chain ran but nothing was published | `{last_plugin_update:{ok:true, step:"already_current"}}` | The old server keeps running, untouched; no restart, no error banner. |

The modal notes that an already-open Claude Code session still needs `/reload-plugins` for new skills/commands. It then polls `status` and reloads once the old server went down and answered again, or as soon as a different `local_version` answers; a verdict of this chain (`finished_at` after the click) that is `ok:false` or `already_current` ends the wait and shows it, since the old server then never goes down. Independently, every tab reloads itself onto the new UI build when its WebSocket reconnects to a server whose `/api/health` `version` is not the bundle's (`client/src/lib/newBuildReload.ts`, once per version). |
+| Plugin chain ran but nothing was published | `{last_plugin_update:{ok:true, step:"already_current"}}` | The old server keeps running, untouched; no restart, no error banner — a tab waiting on **Update now** stops waiting and says nothing new was pulled. |
 | Plugin chain mid-handover | `{last_plugin_update:{ok:true, step:"bootstrap", note:"the new plugin version is installed; the server is being handed over"}}` | Written BEFORE the handover on purpose: that step retires the process tree the helper hangs off, and a helper killed there would otherwise leave `last_plugin_update: null` for an update that succeeded. Overwritten by `done` when the helper survives. |

A `bootstrap` failure means the old server was already stopped, so the verdict says to run `/agenthub-update` to recover — and it is read back by whichever server comes up next, because it lives outside the cache. |
 | Plugin `/apply` with nothing newer published | 409 `{reason:"plugin_managed", release_check:"ok"}` | No chain is spawned. Message names the newest release and points at `/agenthub-update` to force a refresh. |
 | Plugin `/apply` after a failed release check | 409 `{reason:"plugin_managed", release_check:"unreachable"\|"no_local_version"\|...}` | No chain is spawned, and the message says the check did not succeed rather than claiming nothing newer exists — an unknown reported as a negative is how a broken check looks identical to an up-to-date install. |
 | Healthy, behind, on canonical branch | `{update_available:true, situation:"tracking_canonical", manual_command:"...git pull --ff-only..."}` | Modal opens with `git pull` flow + restart hint. |
 | Healthy, behind, fork (origin = fork, upstream = canonical) | `{update_available:true, situation:"fork_or_diverged_tracking", manual_command:"...git fetch upstream && git merge --ff-only upstream/master..."}` | Modal opens with merge flow + restart hint + `situation_note` explaining the divergence. |
+| Newer release, but HEAD holds commits the release lacks (e.g. local wip the release squashed) | `{update_available:true, situation:"diverged_from_release", manual_command:"...git fetch <remote> --tags"}` | Modal opens with no **Update now**; `situation_note` says how many commits diverge and offers `git reset --keep <tag>` (when they are already in the release) or merge/rebase. `/apply` answers `not_fast_forwardable` instead of a raw `merge --ff-only` failure. |
 | Healthy, behind, on a feature branch | `{update_available:true, situation:"feature_branch", manual_command:"...git fetch <remote>"}` | Modal opens; `situation_note` explains the user is off the canonical branch; restart hint suppressed because the working tree isn't being changed. |
 
 ### Why Self-Apply Stays Narrow
@@ -2316,7 +2325,7 @@ The same shape is used by `GET /status`, `POST /check`, and the `update_status`
 - **Branch coverage.** A feature branch or detached HEAD would need branch-aware integration (rebase vs merge vs switch) and merge-conflict handling. That belongs in the user's shell, not in a background daemon — which is why those situations get a printed `git fetch` and no button.
 - **Ownership.** A plugin-cache install is not ours to rewrite by hand — its directory names are content hashes Claude Code manages. So that case does not fast-forward anything; it calls `claude plugin update` and then re-runs `plugin-bootstrap.js` from the directory that tool produced. The residual limit is only `/reload-plugins`, which is REPL-scoped: an interactive session keeps its old skills/commands until the user reloads, even though the dashboard server has already moved.
 
-What `--ff-only` buys is the absence of the first three problems inside the supported cases: the move is either a clean fast-forward or it aborts, `npm run setup`/`build` failures reject the request before any restart is scheduled, and the restart itself goes through `self-restart.js` + the detached `scripts/restart-helper.js` rather than an in-process guess at the supervisor.

A detached replacement under a `Restart=always` unit held the port while the unit restarted every 3 s, each start exiting "already running" (v2.7.2).

An error alerts on the transition INTO `error` only, and **Clear alerts** (`clearErrors`) moves the errored sessions into `dismissed`: their later updates, agent errors and failure events stay silent until the session goes active again or ends. `attentionOf` lists errored then waiting sessions by name; `MOMENT_OF_PULSE` maps each pulse to a pet animation.

The reducer runs outside React's updater so StrictMode never doubles a pulse. Produces `{ mood, status, attention, bubble, moment }`. |
 | **`SagiAvatar.tsx`** | Pure presentational SVG mascot. The `data-mood` attribute drives CSS; pupils track the cursor. Rendered at 90×90 px (`size` default, kept in sync with `SAGI_SIZE` in `useSagiPosition.ts`, which is the draggable button's real footprint) through a `viewBox` cropped to the artwork's measured bounding box instead of the exporter's padded `0 0 1280 1280` canvas. Path data is never rescaled, so `MAX_PUPIL_SHIFT` stays in the original 1280-unit space. The `transform-origin` values in `sagi.css` do **not**: an origin on an inner SVG element resolves against `transform-box: view-box`, whose 0,0 sits at the `viewBox` min (`253.5 106`), so those are mascot coordinates **minus that offset**. The root `.sagi-avatar` origin is a percentage on purpose — on the outermost `<svg>` a length would be measured against the 68 px CSS box, and the resulting ~9× overshoot turns every mood animation into a whole-avatar lurch. |

+| **`PetChat.tsx`** | The pet's chat window (Ask handoff, or **Chat with …** in the panel), styled as a soft accent gradient with chat bubbles. The first message starts a session of the user's default AI tool (`agenthub.defaultTool`; Claude or Codex — any other tool still opens its pane in the workspace) in the "Sagi" workspace's first free tab; replies are read from the session's transcript every 1.5 s, and follow-ups and menu answers (`PaneMenuCard`) go through a `TerminalView` attached off-screen (`submitToRun`), so no new route exists. The chat is kept in `localStorage` (`agenthub.pet.chat`) while its pane lives; an ended pane is never resumed — the next message starts a new session. |
+| **`Sagi.tsx`** | Shell component. A pat (the panel's heart, the Ask box, or stroking the pet — four left/right turns of the pointer over it within 1.2 s) shows hearts and a line ON the pet, so it reads while the panel or chat is open. Mounted once in `client/src/components/Layout.tsx` as a sibling of `UpdateNotifier`. Owns open/closed state, the `⌘B` / `Esc` shortcuts, reduced-motion detection, and navigation. |

+
+## Requirements
+
+- **Node.js ≥ 22.5**
+- **git**
+- **tmux**
+
+To install them:
+
+- Ubuntu: `sudo apt install git tmux` (get Node.js ≥ 22.5 from <https://nodejs.org>)
+- macOS: `brew install node git tmux`
+
+<a id="install-claude-code"></a>
+
+## Option 1 — Install through Claude Code (recommended)
+
+Send **each line on its own** straight into the Claude Code chat:
+
+```
+/plugin marketplace add https://git.smartgift.io.vn/Smartgift-AI/AgentHub.git
+```
+
+```
+/plugin install agenthub@agenthub
+```
+
+```
+/agenthub:agenthub-open
+```
+
+The last one prints the dashboard's address (by default <http://localhost:4820>) —
+open it in the browser and you are done.
+
+Something wrong? Send `/agenthub:agenthub-doctor` to check and fix it.
+To update to a new version: `/agenthub:agenthub-update`.
+Not using it? Quit so nothing runs in the background: **Settings → System → Quit**,
+or `agenthub stop` — opening Claude Code no longer starts it; `agenthub start` does.
+AgentHub's icon beside the clock (top bar / menu bar / notification area) offers
+**Open**, **Quit** and **Start AgentHub** too; hide it from its menu or in **Settings → System**.
+
+<a id="install-terminal"></a>
+
+## Option 2 — Install from a terminal (without Claude Code)
+
+Run these in a terminal, one after another:
+
+```bash
+git clone https://git.smartgift.io.vn/Smartgift-AI/AgentHub.git
+cd AgentHub
+npm run setup      # install the dependencies + the agenthub command
+npm run build      # build the UI
+npm start          # run the dashboard
+```
+
+Open <http://localhost:4820> in the browser.
+
+`npm start` stops when the terminal closes. To have the dashboard start every time
+the machine boots:
+
+```bash
+agenthub service install
+```
+
+> ⚠️ Pick **only one** of the two options. With both installed, every event is
+> counted twice.

-sessions, workspace runtimes, and Claude Code's own configuration.

-## Main features
+## Yêu cầu
 
-**Observe**
+- **Node.js ≥ 22.5**
+- **git**
+- **tmux**
 
-- **Sessions, agents, events.** Everything Claude Code emits, recorded and
-  searchable: tool calls, token usage, cost, subagent trees, transcripts.
-- **Analytics and cost.** Per-model token totals and estimated cost, with
-  editable pricing rules; top tools, agent types, and workflow patterns.
-- **Activity feed and alerts.** A live event stream, alert rules, and webhook
-  targets that fire on them.
-- **History import.** Every session under `~/.claude/projects/` is imported on
-  startup; archives from another machine come in through Settings → Import
-  History (idempotent, never double-counts tokens).
-- **Remote sources.** Pull session history from other machines over SSH
-  (`agenthub remote-sources`).
+Cài:
 
-**Drive**
+- Ubuntu: `sudo apt install git tmux` (Node.js ≥ 22.5 tải ở <https://nodejs.org>)
+- macOS: `brew install node git tmux`
 
-- **Workspaces.** One workspace per working directory, surviving session restarts. Once you
-  install a pipeline template (none ships), a workspace moves through its stages and
-  the dashboard shows where it is.
-- **Stage detection.** With a template installed, the stage is inferred from the
-  tool stream, so a session that never calls `agenthub stage` still shows
-  progress — rendered dashed amber and never as done, because an inference is
-  not evidence.
-- **Run Claude Code or Codex from the browser.** A real terminal (tmux + a real
-  PTY, rendered with xterm.js) attached to a workspace's directory — the exact TUI
-  you'd see locally, fully interactive, resumable, and attachable from a real
-  terminal too via `agenthub workspace shell`. Which CLI it starts is the workspace's own
-  setting. **This is the part that needs `tmux` installed** — see
-  [Prerequisites](#prerequisites).
-- **Git, from the dashboard.** Each workspace card shows its branch, `↑ahead ↓behind`
-  and its uncommitted files, with buttons for the ordinary moves: fetch, pull
-  (always `--ff-only`), push, commit-all, and switching branch on a clean tree.
-  Beside the workspace sits a collapsible **Changes** panel — an overview of the
-  changed files, a full review of every diff, or one file at a time, comparing
-  either uncommitted work or the whole branch against its base. There is no
-  merge/rebase/reset button by design: recovery from those needs a terminal.
-- **Per-workspace app stacks.** A repo that declares `.agenthub/profile/` gets its own
-  slot, ports and services per workspace (`agenthub workspace up|down|logs`).

-**Configure**
+## Cách 1 — Cài qua Claude Code (khuyên dùng)
 
-- **Workspaces like Claude Desktop projects.** The sidebar lists every
-  workspace with its sessions under it (a live one opens its tmux pane, any
-  other its conversation with a prompt box — sending a message resumes it,
-  opening never does; **Analyst** in the right panel opens its analysis). A workspace opens on its home: a
-  prompt box that starts a new session, Recents, and the workspace's own
-  Instructions, Memory, Context files and extra Folders, which Claude and Codex
-  sessions start with.
-- **Settings as one page per section** (`/settings/<section>`): a left nav
-  grouped General (General / Data / About / Appearance / Pet / Notifications) /
-  Agents / Routing / Cost / Git, a search box (Ctrl+F) over every section whose
-  results deep-link a row's sub-tab and anchor, a page per installed AI tool, per-vendor model pricing, and which
-  untracked worktrees a workspace's Add folder suggests.
-- **Claude Code + Codex configuration explorer.** Settings hosts one page per
-  tool: every plugin, skill, subagent, slash command, MCP server, hook, settings
-  file, memory file, marketplace, keybinding and statusline Claude Code knows
-  about — read for all of them, edit/create/delete for the text-file surfaces
-  (skills, agents, commands, output styles, `CLAUDE.md`). Plugins, MCP, hooks and
-  `settings.json` stay read-only: they race with the live CLI.
-- **Updates.** Release-based update detection with an in-UI **Update all**
-  (marketplaces → every plugin → AgentHub last → one session reload).
-- **Appearance.** Settings → Appearance picks Dark / Light / System (follows the
-  OS live) and a theme per mode — dark: Default, Darcula, Apple Dark, Orca Dark;
-  light: Default, Apple Light, IntelliJ Light, Canvas, Orca Light. Each mode
-  remembers its own theme, so the sidebar's quick toggle swaps between the two.
-  Per-browser only.
-- **Notification sounds.** Settings → Notifications picks a sound (None, Chime,
-  Pop, Alert — off by default) played with every notification shown, and each
-  notification type can pick its own.
-- **A CLI for all of it** (`agenthub`, plus `agenthub repl`), a PWA install, and
-  a UI in English, Vietnamese, Chinese and Korean.
-- **Outside the dashboard, all opt-in:** a read-only MCP server
-  (`claude mcp add agenthub -- agenthub mcp`, [docs/MCP.md](docs/MCP.md)), a
-  Claude Code statusline with session and today's cost
-  (`agenthub statusline install`, [docs/STATUSLINE.md](docs/STATUSLINE.md)), and
-  Prometheus rules + Grafana boards for `/api/metrics`
-  (`docker-compose.monitoring.yml`, [docs/MONITORING.md](docs/MONITORING.md)).
-
-## Prerequisites
-
-| Need | Version | Required for |
-|---|---|---|
-| **Node.js** | >= 20 (>= 22.5 for a plugin install) | Everything. Both suites are verified green on **24** and **26** |
-| **npm** | 9+ | Ships with Node |
-| **git** | any | Cloning, and every workspace operation (worktrees, branch/status reads) |
-| **tmux** | 3.x | The browser run console, `agenthub workspace shell`, typing `/reload-plugins` into a live pane |
-| **Claude Code** | 2.x | Hook ingestion — the whole monitoring side |
-| **Codex CLI** | any | Optional — only for `codex` workspaces |
-| **GitHub CLI (`gh`)** | any | Optional — only for `agenthub workspace ci status` |
-| **systemd (user)** | — | Optional — only for `agenthub service install` (Linux auto-start on boot) |
-
-Node **25** is the one version to avoid: it breaks 6 server tests through a
-better-sqlite3 ABI mismatch and 20 client tests through a global `localStorage`
-change. Both were gone again by 26 (1712 server + 488 client tests green on
-v26.8.1).
-
-### Installing tmux
-
-The dashboard shells out to the `tmux` binary; there is no bundled fallback, so
-**Start Run** and `agenthub workspace shell` fail without it. Everything else
-(sessions, analytics, workspaces, stage detection, the CLI) works fine.
-
-```bash
-sudo apt install tmux        # Debian / Ubuntu
-sudo dnf install tmux        # Fedora / RHEL
-brew install tmux            # macOS
-sudo pacman -S tmux          # Arch

-Windows has no native tmux — run AgentHub under WSL2 and install it there.
-
-macOS (code-audited, untested on a Mac): `brew install node git tmux` (Node
->= 22.5 for the plugin), add `~/.local/bin` to `PATH` in `~/.zshrc`. There is
-no systemd, so the dashboard runs until logout/reboot and comes back at the
-next Claude Code session, or by hand with `agenthub start`. Details and a
-checklist to verify it: [INSTALL.md § macOS](INSTALL.md#macos).
-
-Verify, both from your shell and from the server's point of view:
-
-```bash
-tmux -V                                      # e.g. tmux 3.4
-curl -s localhost:4820/api/run/tmux          # {"available":true}
-```
-
-A workspace's run lives in a tmux session named `agenthub-lane-<id>`, so the browser
-terminal and a local `tmux attach -t agenthub-lane-<id>` (or `agenthub workspace
-shell`) are two clients on the same pane — they stay in sync, and killing the
-dashboard never kills the run.
-
-## Install as a Claude Code plugin
-
-Two commands on a machine that has nothing but Claude Code, no clone and no
-`npm run setup`:
+Anh chị hãy gửi **riêng từng dòng** sau thẳng vào khung chat Claude Code:
 
 ```
 /plugin marketplace add https://git.smartgift.io.vn/Smartgift-AI/AgentHub.git
+```
+
+```
 /plugin install agenthub@agenthub
 ```
 
-The first session start installs the hooks, boots the server, puts `agenthub` on
-PATH; it runs detached, so the session never waits on
-it. `/agenthub-doctor` reports the state, `/agenthub-open` builds the UI and prints the
-URL, `/agenthub-update` refreshes after a plugin update. This path needs Node
-**>= 22.5** (no native `better-sqlite3`, so the server uses `node:sqlite`).
-Details, including what to delete on uninstall:
-[`docs/PLUGINS.md`](docs/PLUGINS.md).
-
-## Install from a checkout
-
-```bash
-npm run setup          # root and client dependencies
-npm run build          # builds the client into client/dist
-npm start              # serves the built client and the API on :4820
+```
+/agenthub:agenthub-open
 ```
 
-Open <http://localhost:4820>.
+Dòng cuối in ra địa chỉ dashboard (mặc định <http://localhost:4820>) — mở nó
+trên trình duyệt là xong.
 
-Development, with hot reload:
+Gặp lỗi thì gửi `/agenthub:agenthub-doctor` để tự kiểm tra và sửa.
+Cập nhật bản mới: `/agenthub:agenthub-update`.
+Không dùng thì tắt hẳn cho khỏi chạy ngầm: **Settings → Hệ thống → Thoát**, hoặc
+`agenthub stop` — mở Claude Code sẽ không tự bật lại; bật lại bằng `agenthub start`.
+Gỡ hẳn khỏi máy: **Settings → Hệ thống → Gỡ cài đặt**, hoặc `agenthub uninstall`
+(chỉ liệt kê) rồi `agenthub uninstall --yes` — xoá cả database của AgentHub; các cuộc
+trò chuyện của Claude Code/Codex, worktree và repository của bạn được giữ lại.
+Icon AgentHub cạnh đồng hồ (thanh trên cùng / menu bar / khay hệ thống) cũng có
+**Open**, **Quit** và **Start AgentHub**; ẩn nó trong menu của icon hoặc ở **Settings → Hệ thống**.
+
+<a id="install-terminal"></a>
+
+## Cách 2 — Cài bằng terminal (không qua Claude Code)
+
+Chạy lần lượt trong terminal:
 
 ```bash
-npm run dev            # server on :4820, Vite client on :5173
+git clone https://git.smartgift.io.vn/Smartgift-AI/AgentHub.git
+cd AgentHub
+npm run setup      # cài thư viện + lệnh agenthub
+npm run build      # build giao diện
+npm start          # chạy dashboard
 ```
 
-`DASHBOARD_PORT` overrides the port, `DASHBOARD_CLIENT_DIST` overrides where the
-built UI is served from (defaults to `client/dist`; the plugin install points it
-at its own runtime directory). `postinstall` writes the Claude Code hook entries
-that feed the dashboard — do not run it when the `agenthub` plugin is installed, or
-every event is counted twice.
+Mở <http://localhost:4820> trên trình duyệt.
 
-### Run as a service (auto-start on boot)
-
-`npm start` only runs while that terminal (or `agenthub start`'s background
-process) is alive — a reboot loses it. `agenthub service install` sets up a
-systemd `--user` service (Linux) or a LaunchAgent (macOS) instead, so `:4820` is up again on its own after
-every reboot, with no manual step and no Claude Code (or any AI tool) needed
-to trigger it:
+`npm start` tắt khi đóng terminal. Muốn dashboard tự chạy mỗi lần bật máy:
 
 ```bash
-npm run build              # the service serves the built client, same as npm start
-agenthub service install       # Linux: ~/.config/systemd/user/agenthub.service
-                               # macOS: ~/Library/LaunchAgents/io.smartgift.agenthub.plist
-agenthub service status        # systemctl --user status / launchctl print
-agenthub service uninstall     # disable and remove it
+agenthub service install
 ```
 
-On Linux, `agenthub service install` also tries `loginctl enable-linger` so the service
-starts on a cold boot, before anyone logs in; if that needs elevated rights on
-your machine it prints the `sudo loginctl enable-linger <user>` command to run
-once yourself. The same is a switch in the dashboard — Settings → About →
-**Start AgentHub automatically** (off by default; it enables or disables the
-unit and never stops the running server). Plugin installs get it only once
-that switch is on — see
-[Auto-start on boot](docs/PLUGINS.md#auto-start-on-boot) in `docs/PLUGINS.md`.

-`agenthub --help` lists the rest.

-## Workspaces
-
-A workspace is a working directory the dashboard watches. Two kinds:
-
-- **adopted** — a directory you already had. The dashboard only reads it; it is
-  never reset or deleted.
-- **managed** — a git worktree the dashboard created under `LANES_ROOT`. It may
-  reset that worktree, behind a three-check destroy guard and a counted preflight
-  the caller has to echo back. Removing a workspace — either kind — deletes only the
-  dashboard's record of it: the working tree, its branch and its database stay,
-  for you to delete yourself.
-
-```bash
-agenthub workspace add --cwd /path/to/repo --title "My feature"    # adopt
-agenthub workspace add --repo /path/to/repo --slug my-feature      # managed worktree
-```
-
-Every workspace also carries the CLI that drives it — `claude` (the default) or
-`codex` — picked in the Add-workspace modal and fixed for the life of the workspace. A
-Codex workspace's run panel offers Codex's own sandbox, approval and reasoning-effort
-choices, and resumes with `codex resume --last`. Codex sessions and token usage
-are read from Codex's own rollout journals: every Codex session (a workspace's or
-not) appears in Sessions with a **Codex** badge and is priced like any other,
-with OpenAI rates filled in automatically (Settings → Codex → Overview). For a
-live feed, install **Codex hooks** from the same tab: the next time Codex starts
-it asks you to trust them (**Trust all and continue**), and from then on each
-tool call lands in the session's timeline, a codex workspace turns running/idle as
-each turn starts and ends, and "Codex needs your permission" shows on the workspace
-card and as a notification while Codex waits for an approval. A Codex workspace also
-carries **no pipeline** — no stage, no pipeline map, nothing inferred or
-advanced; without hooks the dashboard mirrors its running/idle status from the
-rollout journals on disk (`$CODEX_HOME/sessions/**/rollout-*.jsonl`, polled
-every `DASHBOARD_CODEX_POLL_MS` ms, default 15000).
-
-An **Antigravity** workspace runs Antigravity's `agy` CLI. Its sessions and token
-usage are read from agy's own conversation files
-(`~/.gemini/antigravity-cli/conversations/<id>.db`, every
-`DASHBOARD_ANTIGRAVITY_POLL_MS` ms, default 15000): every agy CLI session
-appears in Sessions with an **Antigravity** badge, priced with Gemini rates that
-are filled in automatically (Settings → Antigravity). **Antigravity hooks**, in
-the same tab, add a live feed: each tool call in the session's timeline and a
-workspace that turns running/idle as a run starts and ends. agy asks for no trust,
-and it has no hook for a permission prompt, so an Antigravity workspace never shows
-"needs your permission". agy fires no hook when it exits, nor when a run ends
-on an API error or a permission refused in headless mode, so a session gone
-quiet is marked completed and its workspace set idle — after ten minutes of quiet
-for a session the hooks report on (a long tool call writes nothing, and after a
-Stop agy may still be waiting for you), after two minutes for one without
-hooks. Antigravity workspaces carry no pipeline either.
-
-**Cursor** sessions — the Cursor CLI's and the Cursor editor's agent chats — are
-read from Cursor's agent transcripts
-(`~/.cursor/projects/*/agent-transcripts/`, every `DASHBOARD_CURSOR_POLL_MS` ms,
-default 15000) and appear in Sessions with a **Cursor CLI** badge. Cursor writes
-no token counts or model ids there, so a Cursor session shows no tokens and no
-cost.
-
-**Pipelines are dormant.** AgentHub ships no pipeline template, so a workspace has no
-stages until you drop a template JSON into `DASHBOARD_PIPELINES_DIR` (see
-[`docs/LANES.md`](docs/LANES.md#custom-pipeline-templates)); until then
-`agenthub stage` answers `ENOPIPELINE` and the Workspace hides the pipeline map.
-Further development is planned.
-
-The declared stage comes from `agenthub stage`. The inferred stage comes from tool
-events and expires after `DETECTION_TTL_MS` (default 5 minutes), so a workspace can
-move backwards between work sessions. Detection never writes the declared stage,
-and an inferred node never renders as done.
-
-A workspace's pipeline template can be switched after creation — `agenthub workspace
-pipeline <template>` from the terminal, or the pipeline-template picker next to
-the workspace's title in the Workspace detail panel. Both re-resolve the workspace's
-current declared stage against the new template's nodes and warn if it no
-longer matches one.
-
-A workspace can also run **its own application stack**, isolated per workspace, when its
-repository declares a profile at `<repo>/.agenthub/profile/` — a `profile.env` of
-declarations plus shell hooks the dashboard calls. Each workspace gets a slot, and its
-ports and per-workspace directories derive from it:
-
-```bash
-agenthub workspace up          # boot the stack of the lane owning this directory
-agenthub workspace runtime     # slot, ports, service health
-agenthub workspace logs api    # tail a service log
-agenthub workspace down
-```
-
-Services are fully detached, so restarting the dashboard never stops a running
-workspace. This is resource namespacing on the host, not a container: workspaces run as the
-same user and share the network.
-
-[`docs/LANES.md`](docs/LANES.md) has the pipeline model, the destroy guard, the
-preflight contract, the Workspace page, the git surface (`GET /api/lanes/:id/git`,
-`/git/changes`, `/git/log`, `/git/file`, `/git/ls`, `/git/tree`,
-`POST /:id/git/:action`), and the full
-runtime/profile contract.
-
-## Tests
-
-```bash
-npm run test:server    # node:test
-npm run test:client    # Vitest
-```
-
-Both must be green before a commit. The pre-commit hook (`.husky/pre-commit`)
-runs Prettier, then the tests the commit needs: both full suites for a big or
-risky commit (over 10 code files, a dependency, build/test config or the hook
-itself, a deleted file), only the related tests for a small one (`vitest
-related` for `client/`, the server test files that name each other staged
-module), nothing for docs alone. `AGENTHUB_FULL_TESTS=1 git commit …` forces
-both full suites.

Settings → Appearance → **Text size** (`#text-size`) sets `agenthub.ui.fontSize` = 14|16|17|18 (Small/Default/Large/Larger), the ROOT font size in px (`lib/fontSize.ts`; the index.html script applies it before first paint too); Tailwind's sizes are rem and `index.css` re-states every `text-[Npx]` class in rem, so all text scales with it. All of these keys are synced to the account like the theme (`PREF_KEYS` in `lib/userPrefs.ts` and `server/routes/me.js`)
 
-  **The surface ramp means elevation, and it runs the same direction in both themes: a higher index is LIGHTER in dark and LIGHTER in light.** So in light mode the page is the *darkest* step (`surface-0`, `#e8e5da`) and a `.card` is brighter than the page it sits on (`surface-3`, `#f5f3ec`), which is also what makes every `hover:bg-surface-N` lift rather than dim. Light mode originally used Radix slate in its native direction — index up meant darker — which inverted the whole language: a near-white page (the glare complaint) under grey cards that read as recessed. Never "fix" a light-mode colour by swapping which step a component uses; fix the value of the step.
+  **The surface ramp means elevation, and it runs the same direction in both themes: a higher index is LIGHTER in dark and LIGHTER in light.** So in light mode the page is the *darkest* step (`surface-0`, `#eceef2`) and a `.card` is brighter than the page it sits on (`surface-3`, `#fdfdfe`), which is also what makes every `hover:bg-surface-N` lift rather than dim. Light mode originally used Radix slate in its native direction — index up meant darker — which inverted the whole language: a near-white page (the glare complaint) under grey cards that read as recessed. Never "fix" a light-mode colour by swapping which step a component uses; fix the value of the step.
 
   Other rules that fall out of this:
-  - **Light mode's hue family is warm, dark mode's is cool.** The light ramp is Claude's own ivory/terracotta (`#e8e5da` → `#fcfbf7`, warm neutrals, warm `--shadow-card`), not Radix slate: a cool near-white page reads as glare at any lightness, because the brightest thing on screen is also the bluest. Dark mode stays slate + blue — a warm accent on a near-black page is a different problem with a different answer.
-  - Light `--accent` is **not** the dark one, in hue or in step. Dark's `#0090ff` is 3.3:1 on white; Claude's brand terracotta `#cc785c` is 3.1:1 on ivory and 3.3:1 under white text, so it works as a large fill and fails as a link or a button label. Light mode uses it three steps down, `#924224` (it was `#a34a28`, which missed 4.5:1 as text on its own selected chip).
+  - **The light Default is IntelliJ Light's palette** (`#eceef2` → `#ffffff` neutrals, blue accent, IntelliJ's editor syntax colours); the separate IntelliJ Light theme was folded into it.
+  - Light `--accent` is **not** the dark one: dark's `#0090ff` is 3.3:1 on white. Light mode uses IntelliJ's `#285ac0`, dark enough to clear 4.5:1 as text and under white.
   - **White text sits on `accent-solid`, never on `accent`.** `--accent` is a TEXT colour; in the dark themes it is the light step (Default `#70b8ff`, Orca Dark `#6aa0f8`) that reads on a near-black card and is far too light to carry white. Every theme also defines `--accent-solid`/`--accent-solid-hover` (Tailwind `bg-accent-solid`) for the fill behind white text — `.btn-primary`, a Switch's on state, a Checkbox tick — darkened until white clears 4.5:1 (Default `#0076d1`). In the light themes the text accent is already dark enough, so `--accent-solid` is simply `var(--accent)`.
   - `--fg-muted` carries real content (timestamps, counts), so it is held at ≥4.5:1 (`#686359`, 5.4:1 on a card), not at the decorative value the Radix step suggests.
   - Code colouring goes through the `syntax.*` tokens (`--syn-*`), never fixed Tailwind steps: the dark set is pastel (300-level), the light set is the same hues four steps darker, because a pastel keyword on a light code block is unreadable.

+ * mode — the default — it renders the app and nothing else changes, at once
+ * when this browser last saw local mode (`agenthub.authMode`); in server mode it renders the login page until
+ * someone logs in, and again whenever a request answers 401 `EAUTH`
+ * (`AUTH_REQUIRED_EVENT`). Logging out unmounts the app, so no page keeps the
+ * previous user's data. `useAuth()` gives the sidebar the user, `logout`, and
+ * `updateUser` (Settings → Account's saved display name shows at once);
+ * `usePermissions()` says what that user's role may do, so pages hide the rest.
+ * Once an account is known (local mode is one), its own UI preferences are
+ * loaded into this browser (`lib/userPrefs.ts`).
+ * The login page follows the OS's light/dark (`applySystemTheme`).

+/**
+ * @file InterruptedSessionsPrompt.tsx
+ * @description The app-wide "resume interrupted sessions?" dialog. A session
+ * whose pane died under it — the machine shut down, tmux was killed, the CLI
+ * crashed — is listed by `GET /api/run/interrupted`; the user ticks the ones
+ * to resume (each in the first free tab of its workspace, with its run's
+ * model and effort) or resumes none. Either answer dismisses the whole list,
+ * so it is asked once; a resume that failed stays listed. Refetched on the
+ * `runs_interrupted` broadcast, so a tmux that dies under an open dashboard
+ * asks too. Resuming is the explicit click here, never the dialog opening.
