 - **Pod-sticky routing (MANDATORY for daemon-dependent requests)**: The server runs multiple replicas. Each daemon connects to ONE pod via WebSocket. The ingress uses `:serverId` in the URL path to route requests to the pod holding that daemon's WS. Any endpoint that depends on the daemon (file transfer, session commands, Watch API) **MUST** include `:serverId` in the URL path (e.g., `/api/server/:serverId/...`). In-memory state (download tokens, WsBridge instances, terminal streams) is per-pod — requests without serverId routing will hit a random pod and fail.
 - Server secrets (`JWT_SIGNING_KEY`) are set via environment variables, never committed.
 - E2E tests require tmux. They are auto-skipped when `SKIP_TMUX_TESTS=1` or inside a Claude Code session (`CLAUDECODE` env var set).
+- **MANDATORY — Test session hygiene:** Any e2e/integration test that creates tmux sessions, main sessions, sub-sessions, or temporary projects/cwds **MUST** use naming/path patterns covered by `shared/test-session-guard.ts`. If a new test introduces a new naming family, you **MUST** update `shared/test-session-guard.ts` and its tests in the same change. Leaked test sessions must never persist to `~/.imcodes/sessions.json`, must never be written to the server DB, and must be cleaned from live terminal backends on daemon startup.
 - The server TypeScript project is stricter (`noUnusedLocals`, `noImplicitReturns`). Both daemon and server projects must compile cleanly.
 - **Shared code between daemon, server, and web**: Use `shared/` directory (NOT `src/shared/`). Server tsconfig includes `../shared/**/*`. Import path from server: `../../../shared/foo.js`. Import path from daemon/test: `../../shared/foo.js`. Import path from web: `@shared/foo.js` (Vite alias configured in `web/vite.config.ts`). The `shared/` dir is copied into Docker image by `Dockerfile` (`COPY shared/ ./shared/`). **NEVER** import across project boundaries with `../../../src/` paths — they break at runtime in Docker.
 - **Web tsconfig is stricter** than daemon (`noUnusedLocals`). The Docker build runs `cd web && npm run build` which will fail on unused variables/imports that pass `npx tsc --noEmit` in daemon. Always run `cd web && npx tsc --noEmit` before pushing.

+## Ejecución Supervisada y Auto Audit
+
+IM.codes puede conducir sesiones de agent compatibles turno a turno — un supervisor con tus propias instrucciones evalúa cada turno completado en el límite idle y decide auto-continuar, devolver el control o disparar un bucle de auditoría, en lugar de que tengas que escribir "continue" cada ronda.

+- **Comprobaciones de finalización en el límite idle.** Cuando un turno termina, IM.codes puede clasificarlo como `complete`, `continue` o `ask_human` y enviar el siguiente continue prompt dentro de la misma sesión.
+- **Automatización fail-closed.** Auto supervision permanece visible en la timeline y en el footer, usa decisiones estructuradas y te devuelve el control si hay timeout, salida inválida o mala configuración.
+- **Bucle opcional audit → rework.** En `supervised_audit`, un turno completado puede entrar automáticamente en un pipeline de auditoría y reenviar un brief de retrabajo a la misma sesión antes de devolverte el control.
+- **Valores globales + overrides por sesión.** Define una vez el backend/modelo/timeout por defecto del supervisor y, cuando haga falta, sobrescribe backend/modelo/timeout, modo de auditoría e instrucciones personalizadas en cada sesión.
+- **Pensado para flujos reales de IM.codes.** Auto supervision entiende flujos de OpenSpec, revisiones P2P y coordinación entre agentes con `imcodes send` como pasos válidos del agente, no como una razón inmediata para parar y pedir a un humano.

+## Контролируемое выполнение и Auto Audit
+
+IM.codes может вести поддерживаемые agent session ход за ходом с помощью вашего собственного supervisor-промпта — на каждой idle-границе структурно оценивается завершённый ход и принимается решение auto-continue, вернуть управление или запустить audit-цикл, вместо того чтобы вы вручную набирали "continue" каждый раунд.
+
+- **Режимы Auto на уровне session.** Можно настраивать `off`, `supervised` и `supervised_audit` для каждой session отдельно, не навязывая одну политику всем.
+- **Проверка завершения на границе idle.** Когда ход заканчивается, IM.codes может классифицировать его как `complete`, `continue` или `ask_human` и отправить следующий continue prompt в ту же session.
+- **Fail-closed автоматизация.** Auto supervision остаётся видимым в timeline/footer, использует структурированные решения и возвращает управление пользователю при timeout, невалидном выводе или плохой конфигурации вместо догадок.
+- **Опциональный цикл audit → rework.** В `supervised_audit` завершённый ход может автоматически перейти в аудит, а brief на доработку вернётся в ту же session до возврата управления.
+- **Глобальные значения по умолчанию + переопределение на уровне session.** Один раз задайте default backend/model/timeout для supervisor, а при необходимости переопределяйте backend/model/timeout, режим audit и пользовательские инструкции для конкретной session.
+- **Понимание реальных workflow IM.codes.** Auto supervision понимает OpenSpec-задачи, P2P review/discussion и координацию через `imcodes send` как нормальные следующие действия агента, а не как повод немедленно остановиться и ждать человека.

+## Supervised Execution & Auto Audit
+
+IM.codes can drive supported agent sessions turn by turn — a supervisor with your own instructions evaluates each completed turn at the idle boundary and decides to auto-continue, hand back, or trigger an audit loop, instead of you typing "continue" every round.
+
+- **Per-session Auto modes.** Configure `off`, `supervised`, or `supervised_audit` per session instead of forcing one policy everywhere.
+- **Completion checks at the idle boundary.** When a turn finishes, IM.codes can classify it as `complete`, `continue`, or `ask_human`, then dispatch the next continue prompt inside the same session.
+- **Fail-closed automation.** Auto supervision stays visible in the timeline/footer, uses structured decisions, and returns control to you on timeout, invalid output, or bad config instead of silently guessing.
+- **Optional audit → rework loop.** In `supervised_audit`, a completed turn can automatically enter an audit pipeline and send a rework brief back into the same session before control returns.
+- **Global defaults seed new sessions.** Set your default supervisor backend, model, and timeout once. New `supervised` / `supervised_audit` sessions snapshot them at enable time, and each session can still override backend/model/timeout and audit mode individually.
+- **Two-layer custom supervision instructions.** Keep a global supervision persona alongside a per-session addition. By default the two are concatenated (`global`, blank line, then `session`); tick the session's **Override global** checkbox to ignore the global value for that one session. Unlike backend/model/timeout, the global value is re-read on every dispatch, so editing it takes effect on already-enabled sessions without a re-enable.
+- **Built for real IM.codes workflows.** Auto supervision understands OpenSpec work, P2P discussion/review flows, and `imcodes send`-style cross-agent coordination as valid agent actions, not immediate reasons to stop for a human.

 Full mobile support with biometric auth and push notifications. Shell sessions allow interactive keyboard input on mobile (SSH-like). Sub-session preview cards always show latest messages. Toast notifications navigate directly to the relevant session. Apple Watch support adds quick session monitoring, unread counts, and quick replies from the wrist.
 
+### Supervised Task Automation
+
+Auto supervision adds turn-level control for supported transport-backed agents. Instead of blindly continuing forever, IM.codes evaluates the latest completed turn and decides whether the task looks done, should keep going, or should come back to you. For higher-assurance work, `supervised_audit` can automatically trigger an audit/rework loop before the session is considered finished.
+
+Auto supervision splits configuration into two layers. Backend, model, and timeout are **snapshot-frozen** at the moment you enable Auto on a session, so editing the global defaults later never surprises an already-running session. Custom supervision instructions work differently: a **global persona** is paired with the session's own free text and — by default — both are concatenated into the prompt sent to the supervisor. Tick the session's **Override global** checkbox to have that session ignore the global persona entirely. The global persona is re-read on every turn, so when you update it every already-enabled session picks it up on the next dispatch without needing a re-enable. Auto is also aware of IM.codes-native workflows such as OpenSpec changes, P2P discussions, and `imcodes send`, so those actions count as legitimate next steps instead of accidental "ask human" triggers.
+
 ### Multi-Agent Discussions & Cross-Provider Audit
 
 Single-model output shouldn't be trusted blindly. P2P discussions let multiple agents — across different providers and thinking styles — collaborate on the same codebase before a single line is written. Each round follows a customizable multi-phase pipeline where every agent reads all prior contributions and builds on them. Different models catch different classes of issues: one spots a race condition, another flags a missing migration, a third questions the API design. This cross-provider scrutiny catches the majority of problems before implementation, dramatically reducing rework cycles.

+ * window are silently dropped by `sendToSessionSubscribers`. A parallel
+ * HTTP backfill fired ~500ms after reconnect reads the daemon store
+ * directly and recovers those events — dedup by eventId makes it safe to
+ * merge alongside the WS path.

+ * Content fingerprinting for processed memory projections.

+ *     reuse the existing row instead of producing a new UUID, and
+ *   - a dedup key for recall-time cleanup so stored duplicates from before
+ *     the store-time fix still collapse to a single card.
+ *
+ * The fingerprint intentionally excludes sourceEventIds, createdAt, and any
+ * content-field noise so a second summary with "same decisions, different
+ * turn" collapses with the first. It includes namespace + class so two

+/**
+ * Per-session recent-injection history.
+ *
+ * Purpose: prevent the same memory items from being re-injected into prompts
+ * on consecutive turns of the same session. Once a memory has been included
+ * in a recall-injected prompt, it becomes low-value to inject again in the
+ * immediate follow-up turns — the model already saw it, and repeating it
+ * is noise.
+ *
+ * Scope:
+ *   - Per session (keyed by `sessionKey` — e.g. `deck_<project>_<role>`).
+ *   - In-memory Map backed by SessionRecord.recentInjectionHistory on disk:
+ *     daemon restart / resume does NOT start from an empty dedup state, so
+ *     the same memory is not re-injected into a conversation that already
+ *     has it in its own agent-side history. Cleared on session `clear` and
+ *     fresh-restart.
+ *   - Does NOT apply to startup bootstrap (which is project-scoped memory
+ *     load, not a query-driven recall) or to server-side recall endpoint
+ *     (no per-session context).
+ *
+ * Semantics:
+ *   - "Last 10 turns" = the last 10 successful injection events, where
+ *     each event carries the set of memory IDs that were injected on
+ *     that turn. Unit is "turn", not "memory id": 1 event with 5 ids
+ *     consumes 1 slot, not 5.
+ *   - A candidate is considered "already injected recently" if its id
+ *     appears in ANY of the retained injection events for this session.
+ *   - The history is a ring buffer: recording the 11th event evicts
+ *     the oldest.

+// compression piles into the same main-thread event loop, so "it's async"
+// doesn't actually protect the loop from multiplicative callback load.
+//
+// The gate is a single Promise chain: each caller awaits the previous
+// one before entering the inner compression path. Releases in `finally`
+// so even a thrown / timed-out compression can't stall the queue.

+
+Notes:
+- Messages are delivered via the daemon's hook server. If the target is busy, the message is queued.
+- The \`--files\` flag attaches file references; format depends on the target agent type.
+- Your session identity is auto-detected from $IMCODES_SESSION.

+- "Audit implementation" means compare implementation against the OpenSpec artifacts, fix gaps directly, and update artifacts too when needed.

+ * CURRENTLY-edited session's `transportConfig.supervision` when a user saves
+ * the Session Settings dialog. Any OTHER session's cached snapshot retains

+ * sessions, `resolveEffectiveCustomInstructions(snapshot)` sees an empty
+ * global layer and the user's "Always commit and push if asked!" never

+ *
+ * This cache is the fallback layer: the daemon polls the user's current
+ * defaults at startup + on each WS reconnect and stores the parsed result
+ * in-process. When a snapshot has no `globalCustomInstructions`, callers
+ * read `getCachedGlobalCustomInstructions()` and use that instead. No code
+ * path silently loses the user's instruction.
+ *
+ * The cache is best-effort: fetch failures do not throw; the daemon falls
+ * through to the (possibly stale) snapshot mirror and continues operating.
+ * A non-null cache is always more recent than a session snapshot that
+ * predates a global-defaults edit.

+/**
+ * killProcessTree — reliable process-tree teardown.
+ *
+ * Motivation
+ * ----------
+ * Several SDKs we shell out to (codex, claude, qwen) are shipped as node
+ * wrappers that internally fork a native binary (e.g. the musl `codex`
+ * app-server). If we only `child.kill('SIGTERM')` the node wrapper, the
+ * native grandchild survives and leaks memory indefinitely. Observed in
+ * production: 20+ orphaned codex app-server pairs accumulating ~2GB after
+ * a few hours of rate-limit probes.
+ *
+ * Sending to a process group (`process.kill(-pid, ...)`) only works when
+ * (a) the parent was spawned with `detached: true`, AND (b) the node
+ * wrapper did not detach its own grandchild into a separate session. The
+ * second condition is outside our control — some SDK wrappers do detach
+ * their native binary, which breaks group-signalling entirely.
+ *
+ * This helper walks the descendant tree via `ps(1)` at kill time, sends
+ * SIGTERM to every pid (leaves first so parents don't immediately fork a
+ * replacement), waits `gracefulMs`, and SIGKILLs any survivors. On
+ * Windows it delegates to `taskkill /T /F` which handles the tree natively.
+ *
+ * Safe to call when the pid is already dead — all kernel errors are
+ * swallowed. Returns when the terminal SIGKILL sweep has been issued
+ * (not when the kernel has finished reaping — that is observable via the
+ * original spawn's 'exit' event if the caller needs it).

+/**
+ * Integration test covering the FULL supervision-on-idle path with the real
+ * `timelineEmitter` and real `supervisionAutomation` wired together — previous
+ * tests mocked one or the other, so the actual production seam was never
+ * exercised.
+ *
+ * Regression scope: user reports "idle 后依旧不触发任何动作和效果" — after the
+ * assistant goes idle, supervision appears to never fire (no "Auto: checking..."
+ * note, no broker decision, nothing). Unit tests for `supervisionAutomation`
+ * only exercise it via direct `registerTaskIntent` + manual timeline emits, and
+ * `command-handler-transport-queue` mocks `supervisionAutomation` entirely, so
+ * no test verified the handshake between `handleWebCommand('session.send')` →
+ * `registerTaskIntent` → `timelineEmitter.emit('session.state', 'idle')` →
+ * `handleTimelineEvent` → `supervisionBroker.decide`.
+ *
+ * This test runs the real emitter + real automation and mocks only the broker
+ * + transport runtime + store, asserting that enabling supervision then sending
+ * a message and transitioning to idle does call `supervisionBroker.decide`.

+   * history before this fires.
+   *
+   * Call sites:
+   *   - Session mount / switch (`cooldownMs = 60_000`): "user just opened a
+   *     window". If the previous backfill for this same session succeeded
+   *     less than a minute ago — e.g. user is flicking A → B → A — don't
+   *     rehit the daemon store; the freshly cached result is authoritative
+   *     enough.
+   *   - WS reconnect (`cooldownMs = 0`): covers the ~10–100ms subscribe-race
+   *     window on the bridge where live events can be silently dropped.
+   *     Reconnects imply a real connection gap, so they deliberately bypass
+   *     the cooldown — missing events after a disconnect is exactly what
+   *     this read exists to recover.
+   *
+   * Safe to call when:
+   *   - `serverId` is unknown → skipped (self-hosted deploys require it).
+   *   - The user switches session mid-flight → the cacheKey-guard in the
+   *     timeout callback discards results for the old session.
+   *   - Backfill returns zero events → cooldown stamp still recorded (the
+   *     fetch confirmed "no gap").
+   *   - Backfill returns null / rejects → cooldown stamp is NOT recorded so
