+## Unreleased
+
+### Breaking Changes
+
+- **Context pruning now opt-in.** Previously tool-result trimming ran by default
+  for all providers; now requires explicit `contextPruning.mode: "cache-ttl"` in
+  `config.agents.defaults` to enable. Matches upstream TS design and prevents
+  silent prompt-cache invalidation on Anthropic.
+
+  Migration — add to `config.json5`:
+  ```json5
+  agents: {
+    defaults: {
+      contextPruning: { mode: "cache-ttl" }
+    }
+  }
+  ```
+
+### Improvements
+
+- **Context pruning cleanup.** Removed redundant Pass 0 (per-result 30% guard),
+  deduplicated double prune call per iteration, added SanitizeHistory to
+  PruneStage for broken tool_use/tool_result pair cleanup.
+- **Context pruning config backfill (migration).** Agents with existing custom
+  `context_pruning` config (e.g., `softTrimRatio`, `keepLastAssistants`) but
+  missing a `mode` field get auto-backfilled with `mode: "cache-ttl"` to
+  preserve their intent after the opt-in flip. Rows with NULL config stay
+  NULL (new opt-in default applies). PG migration 51; SQLite schema v19.

+## Plan Verification Rules
+
+Apply before finalizing any multi-phase plan. Trust-but-verify between scout → planner → final plan.
+
+### Verification discipline (what to verify)
+
+1. **Verify factual claims against code** — re-grep/re-count every number, path, endpoint. Don't copy from scout summaries.
+2. **Trace semantics, not just cite lines** — when plan references existing/upstream code, identify WHEN each field mutates and under WHAT conditions. Line-range citation without control-flow trace = how ports silently invert behavior. Check: every call, or specific branches only?
+3. **No fabricated identifiers / API families** — every symbol in plan must cite `file:line`. RED FLAGS: plausible-sounding wrappers (`Keyring`, `Validator`, `Manager`), centralized packages (`internal/security`, `internal/auth`) that may be scattered, OTel-style (`StartSpan/EndSpan`) when codebase is emit-based. When unsure, `go doc <pkg>` lists actual exported surface. Apply especially when plan says "reuse existing X".
+4. **Struct scope audit before adding state** — verify lifetime (per-request/session/agent/process) before adding a field to an existing struct. "Plausibly per-X" is a red flag — grep construction + ownership. Shared-instance state leaks across isolation boundaries.
+5. **Gate-premise test math** — before asserting "feature X triggers independently of Y", list all early-returns from function entry to X. Math-verify any fixture claiming "X without Y".
+6. **Port = config-shape match** — "faithful port" divergences in config field name/type are silent breaking changes for users copying upstream config. Match upstream shape, or explicitly flag each divergence with rationale in the phase file.
+7. **Verify external API endpoints via `docs-seeker`** — before writing endpoint into plan. Sibling APIs often use different roots.
+
+### Scope & coverage (where to look)
+
+8. **Grep delete scope deep** — `grep -rn '<symbol>' .` whole repo. Stubs often have refs in catalogs/routing/switch cases. Enumerate ALL sites in todo.
+9. **Signature-change callers enumeration** — grep + list all callers explicitly. "Update all callers" insufficient.
+10. **Alias/shim coverage** — enumerate ALL exported symbols via `go doc <pkg>`. Add compile-time signature guards.
+11. **Scout desktop and web separately** — `ui/desktop/frontend/` ≠ `ui/web/`. Different structure, i18n namespaces, test framework presence.
+
+### Phasing & ordering (when)
+
+12. **Re-scout on scope change** — if phase promotes from deferred → active, re-scout. Don't reuse brainstorm summary.
+13. **Cross-phase gates explicit** — "Phase N-1 merged + tests green" in phase Context. Execution order alone ≠ enforcement.
+14. **Zero-coverage characterization test = blocker step** — write byte/request-body fixture test BEFORE migration. Not "recommended".
+15. **i18n keys ordering** — add key + 3 catalogs as explicit todo step BEFORE handler code. Missing key = runtime crash.
+
+### Conventions & finalization
+
+16. **Context key style convention** — check existing `context.go` pattern before introducing new key types. Mixed = code smell.
+17. **Verify pass MANDATORY after rewrite** — spawn fresh Explore/grep to audit planner output. Don't trust self-validation.
+
+**Pattern to avoid:** user asks → planner writes → report "done".
+**Safer pattern:** user asks → scout → planner writes → audit-verify → report.
+
+**Red-team practice:** After planner completes, run `code-reviewer`/`brainstormer` in audit mode: "spot-check 15+ claims vs live codebase". Past catches: fabricated `crypto.Keyring`/`tracing.StartSpan` (agent-hooks plan); inverted TS-port semantics + wrong struct scope + misread early-return gate (context-pruning plan). See `plans/*/reports/audit-*.md` for concrete examples.
+
 ## Post-Implementation Checklist
 
 After implementing or modifying Go code, run these checks:
@@ -207,6 +245,7 @@ Go conventions to follow:
 - **DB query reuse:** Before adding a new DB query for key entities (teams, agents, sessions, users), check if the same data is already fetched earlier in the current flow/pipeline. Prefer passing resolved data through context, event payloads, or function params rather than re-querying. Duplicate queries waste DB resources and add latency
 - **Solution design:** When designing a fix or feature, identify the root cause first — don't just patch symptoms. Think through production scenarios (high concurrency, multi-tenant isolation, failure cascades, long-running sessions) to ensure the solution holds up. Prefer explicit configuration over runtime heuristics. Prefer the simplest solution that addresses the root cause directly
 - **Tenant-scope guards on admin writes:** `RoleAdmin` is not a tenant check. Writes to **global** tables (no `tenant_id` column — e.g. `builtin_tools`, disk config, package mgmt) must gate with `http.requireMasterScope` / WS `requireMasterScope(requireOwner(...))`. Writes to **tenant-scoped** tables must gate with `http.requireTenantAdmin` + SQL `WHERE tenant_id = $N`. Shared predicate: `store.IsMasterScope(ctx)`. See `CONTRIBUTING.md` → "Tenant-scope guards" for the full decision table and anti-patterns.
+- **Skip load / stress / benchmark tests.** Do NOT write throughput benchmarks, p95/p99 latency assertions, or `runtime.ReadMemStats`-based memory-leak tests for regular feature work. They flake on shared CI runners, waste runner time, and rarely catch real bugs. Only add load tests when explicitly requested for a specific investigation. For normal "prove it works" coverage, use unit + integration + chaos tests.

+
+## 3.5 Agent Hooks System
+
+**Lifecycle hooks** allow agents to perform custom logic at key execution points. The system is event-driven (sync/async), integrated into the 8-stage pipeline, and includes audit logging, edition gating, and security safeguards.
+
+### Event Types
+
+| Event | Stage | Sync/Async | Purpose |
+|-------|-------|-----------|---------|
+| **SessionStart** | ContextStage | Async | Fires once per session (first turn); before history loading |
+| **UserPromptSubmit** | ContextStage | Sync | Fires on user message arrival; blocks with hook reason or mutates input |
+| **PreToolUse** | ToolStage | Sync | Fires before each tool execution; blocks tool or mutates arguments |
+| **PostToolUse** | ToolStage | Async | Fires after tool result is processed; non-blocking |
+| **Stop** | FinalizeStage | Async | Fires when session terminates (stop/complete/error) |
+| **SubagentStart** | (Delegate tool) | Sync | Fires before delegated task spawns; blocks delegation |
+| **SubagentStop** | (Domain events) | Async | Fires on delegation completion/failure; non-blocking |
+
+### Handler Types
+
+| Handler | Edition | Config | Semantics |
+|---------|---------|--------|-----------|
+| **Command** | Lite only | `cmd`, `allowedEnvVars` | Exec shell command; stdin=event JSON; stdout=decision JSON; exit 0→allow, exit 2→block; timeout→block (fail-closed) |
+| **HTTP** | All | `url`, `headers` | POST event JSON to webhook URL; parse response for decision, additionalContext, updatedInput; 5xx retry once; 4xx error no-retry; SSRF-hardened with pinned IP |
+| **Prompt** | Phase 3+ | TBD | Integrates custom prompting logic (deferred) |
+
+### Sync vs Async
+
+**Sync hooks** (UserPromptSubmit, PreToolUse, SubagentStart):
+- Block pipeline until decision received
+- Support Copy-on-Write (COW) staged mutations: `updatedInput` buffered, committed only if ALL sync hooks succeed
+- Timeout ≤5s per hook; chain total ≤10s wall-time
+- Rejection blocks the step (e.g., tool not executed, user message not processed)
+
+**Async hooks** (SessionStart, PostToolUse, Stop, SubagentStop):
+- Fire-and-forget via worker pool (default 16 workers, bounded queue 512)
+- Non-blocking (pipeline continues immediately)
+- Timeout per hook; chain budget enforced but no blocking
+
+### Security Model
+
+- **Edition gating**: `CommandHandler` only on Lite edition; attempts on Standard/other editions rejected (defense-in-depth)
+- **SSRF hardening (HTTPHandler)**: Caller supplies net.Dialer pinning resolved IP, blocking loopback/link-local/private ranges; no HTTP redirects (CheckRedirect returns ErrUseLastResponse)
+- **Auth header encryption**: `Authorization` + other sensitive fields in cfg.Config["headers"] encrypted at rest via AES-256-GCM; decrypted only at HTTP send-time
+- **Audit logging**: All hook invocations logged to `hook_executions` table (encrypted, PII-redacted) with dedup_key for idempotency
+- **Loop-depth guard (M5)**: SubagentStart checks recursion depth; max 3 levels prevents infinite delegation chains
+- **Circuit breaker**: Auto-disables hook after 3 consecutive failures in recent window (C4 mitigation)
+
+### Pipeline Integration
+
+Dispatcher wired into `PipelineDeps.HookDispatcher` (nil-safe noop fallback). All 8 stages support hook firing with zero overhead when dispatcher not configured. Example sync hook flow:
+
+```
+1. ContextStage: UserPromptSubmit → Hooks.Fire(sync)
+2. Sync hooks buffer mutations (updatedInput)
+3. All hooks succeed? → Commit mutations, proceed
+4. Any hook rejects? → Discard buffer, abort pipeline, user sees reason
+```

 - **L0 Auto-Injection**: Top-K vault entries injected into system prompt as "relevant context from vault"
 - **Filesystem Sync**: Vault entries exported as `.md` files for manual editing, re-imported with change tracking
 
+### Audio & Voice System (ElevenLabs + Streaming TTS)
+
+**Provider architecture** (`internal/audio/`):
+- **`Manager`**: Central orchestrator dispatching TTS/STT/Music/SFX requests to pluggable providers
+- **`TTSProvider` interface**: Core text-to-speech contract (blocking, buffered response)
+- **`StreamingTTSProvider` interface**: Optional interface for ElevenLabs `/stream` endpoint (chunked audio via `io.ReadCloser`)
+- **Implementations**: ElevenLabs, OpenAI, Edge, MiniMax (phase-gated; STT/Music/SFX partial)
+
+**Voice discovery & caching**:
+- **Voice cache** (`internal/audio/voice_cache.go`): In-memory LRU (cap 1000 tenants, TTL 1h) shared by HTTP `/v1/voices` + WS `voices.list` handlers. Thread-safe with `sync.Mutex` (LRU updates require write lock)
+- **Cache miss recovery**: HTTP handler auto-fetches from ElevenLabs; WS handler requires prior cache warm (provider resolution deferred to Phase 3)
+- **Agent audio context** (`store.WithAgentAudio` / `AgentAudioFromCtx`): Immutable snapshot bundle (AgentID + OtherConfig JSONB) injected by dispatcher before tool dispatch; consumed by `TtsTool.Execute` for voice/model resolution
+
+**Agent-level configuration** (`agents.other_config` JSONB):
+- `tts_voice_id`: ElevenLabs voice ID (e.g., "pMsXgVXv3BLzUgSXRplE")
+- `tts_model_id`: Model choice (eleven_v3, eleven_flash_v2_5, eleven_multilingual_v2, eleven_turbo_v2_5)
+- Resolution precedence: CLI args → agent config → tenant override → provider default
+
+**Web UI voice picker** (`ui/web/src/components/voice-picker.tsx`):
+- Combobox with BM25 search, preview playback button (HTML `<audio>`)
+- Handles preview CDN 403 (expiry) via `onError` → auto-refresh cache
+- Embedded in PromptSettingsSection, bound to `other_config.tts_voice_id`

-**Configuration**: STT proxy URL, timeout (default 30s), optional tenant ID and API key. If transcription fails, the media placeholder remains — no error is surfaced.
+#### Configuration & Decision Rules
 
-**Voice routing**: When `VoiceAgentID` is configured, audio/voice messages are routed to a different agent (e.g., a speech-specialized agent) instead of the channel's default agent.
+**Decision 2 (Conflict rule):** When `builtin_tools[stt].settings.providers[]` is present in the database, it OVERRIDES all legacy channel-specific STT configs. The legacy STT bridge (`STTProxyURL` → `proxy_stt` provider) only activates when the providers list is empty or missing.
+
+| Setting | Behavior |
+|---------|----------|
+| `providers: ["elevenlabs_scribe", "proxy_stt"]` | Try ElevenLabs Scribe first; fall back to legacy proxy |
+| `providers: []` (empty) | Skip all STT; voice → `[Voice message]` fallback |
+| `providers` missing (nil) | Check for legacy bridge at startup; activate if `STTProxyURL` exists |
+
+**Decision 6 (WhatsApp opt-in):** WhatsApp voice message STT is **OFF by default** (`whatsapp_enabled: false`). Rationale: WhatsApp voice messages are end-to-end encrypted; sending audio to an external STT provider breaks E2E encryption. Admins must explicitly toggle STT in the UI at **Config → Audio → STT** and acknowledge the E2E breaking change.
+
+When disabled (default):
+- Voice messages surface in agent context as `[Voice message]` (localized via i18n key `channel.voice_message_fallback`)
+- No audio leaves the device
+
+When enabled:
+- Voice audio is transcribed via the configured STT chain
+- Fallback to `[Voice message]` on failure/timeout (10s wall clock)
+
+#### Per-Channel Behavior
+
+| Channel | STT Support | Notes |
+|---------|:-:|---------|
+| **Telegram** | Yes | Uses unified chain; voice routing via `VoiceAgentID` config |
+| **Discord** | Yes | Standard flow; no special routing |
+| **Feishu** | Yes | Standard flow; no special routing |
+| **WhatsApp** | Yes (opt-in) | Requires explicit admin approval; default OFF |
+
+#### Factory Integration

+- Telegram: `FactoryWithStoresAndAudio(..., audioMgr)`
+- Discord: `FactoryWithAudio(..., audioMgr)`
+- Feishu: `FactoryWithStoresAndAudio(..., audioMgr)`
+- WhatsApp: `FactoryWithDBAudio(..., audioMgr, builtinToolStore)`

+**Filename preservation**: When a user uploads or shares a file with a recognizable name, the channel adapter populates `bus.MediaFile.Filename` with the original filename (e.g., Feishu file display name, Telegram `file_name`). This filename is then sanitized and persisted to disk in the format `{stem}-{8hex}{ext}` (e.g., `báo-cáo-2024-a1b2c3d4.pdf` → `bao-cao-2024-a1b2c3d4.pdf`). The sanitizer supports Vietnamese diacritics, CJK scripts, and filesystem safety. Media without a user-provided filename (voice notes, clipboard pastes) fall back to UUID-only names.

 ### Cancel Handling
 
-When a run is cancelled via `/stop` or `/stopall`, the run context is cancelled but trace finalization still needs to persist. `FinishTrace()` detects `ctx.Err() != nil` and switches to `context.Background()` for the final database write. The trace status is set to `"cancelled"` instead of `"error"`.
+When a run is cancelled via `chat.abort` (WS) or manual stop, the router atomically transitions to "aborting" state, cancels the request context, and waits 3 seconds for the agent goroutine to exit. If it doesn't, the trace is force-marked `cancelled` to prevent orphaned traces.
 
-Context values (traceID, collector) survive cancellation -- only `ctx.Done()` and `ctx.Err()` change. This allows trace finalization to find everything it needs with a fresh context for the DB call.
+During cancellation:
+- HTTP provider streams close immediately (context-aware transport with `ResponseHeaderTimeout`; SSE body closes via goroutine wrapper to unblock socket read)
+- Tool execution terminates (shell: process-group kill; browser: page close)
+- Agent loop receives `ctx.Done()` and propagates cancellation up
+
+Trace finalization persists independently with a detached context (`context.WithoutCancel`), 5-second timeout, and exponential backoff retry (3 tries, max 10 total via retry queue). This ensures trace status writes don't fail silently due to cancellation.
+
+Stale recovery is **currently disabled**. The implementation exists but the background loop is not started in `Collector.Start()`. Reason: the sweep condition is `start_time < NOW() - threshold`, which measures trace age rather than inactivity. Any threshold low enough to be useful (2–10 min) would kill healthy long-running agent runs (research chains, large code generation, extended shell commands). Re-enable only after adding a `last_span_at` column so recovery can gate on "no activity for N minutes" instead of "started > N min ago". Until then, zombie traces from gateway crashes may remain `running` in the DB — an accepted safety-net gap traded against false kills. The primary abort path (router 2-phase abort + `trace.status` WS event) handles the common case. Context values (traceID, collector) survive cancellation — only `ctx.Done()` and `ctx.Err()` change.

+### ACTOR vs SCOPE — #915 group permission fix + propagation (2026-04-16)
+
+Resolves Issue #915 (Telegram group `write_file` permission denied after `/addwriter`) and closes an adjacent silent-privilege-bypass discovered during the audit.
+
+#### Security (breaking behavior in group/guild context)
+
+- **`store.CheckFileWriterPermission` / `CheckCronPermission`** no longer fail-open on empty or synthetic `SenderID` when the context scope is a group/guild. Previous fail-open allowed subagent/delegate/team/dashboard/cron system turns to write files in group chats without a writer grant — silent privilege bypass. Post-fix: empty or synthetic-prefix senders (`subagent:`, `notification:`, `teammate:`, `system:`, `ticker:`, `session_send_tool`) are DENIED in group context. DM / HTTP paths unchanged.
+- **`bus.IsInternalSender`** now also recognises `subagent:` prefix (previously missed, causing subagent senders to be treated as real users in permission checks).
+
+#### Added — propagation of the acting sender through re-ingress
+
+- `tools.MetaOriginSenderID` metadata key (`origin_sender_id`) — carries the real acting sender through synthetic-sender announce/dispatch paths.
+- `tools.AnnounceMetadata.OriginSenderID` field — subagent/delegate announce queue.
+- `tools.SubagentTask.OriginSenderID` field — populated at spawn from `store.SenderIDFromContext(ctx)`.
+- `cmd.subagentAnnounceRouting.SenderID` — carries sender from handler into the re-ingress `RunRequest`.
+- `tools.DelegateRequest.SenderID` field — same propagation for delegate announcements.
+- `store.ActorIDFromContext(ctx)` helper — returns `SenderID` if set, else `UserID`. Clarifies ACTOR vs SCOPE at call sites.
+
+#### Changed — ACTOR migration (call sites now use `ActorIDFromContext`)
+
+- `internal/tools/publish_skill.go`: skill owner = actor (individual, not group principal).
+- `internal/tools/skill_manage.go` (create, patch, delete): owner = actor on create; patch/delete ownership check accepts actor or legacy `UserIDFromContext` for backward compatibility with skills created before this change.
+- `internal/tools/delegate_tool.go`: `DelegateRequest.UserID` and `DomainEvent.UserID` = actor for audit trails.
+- `internal/tools/team_tasks_blocker.go`: blocker attribution and escalation `UserID` = actor.
+- `internal/tools/team_tool_cache.go`: team access-policy check uses actor (fixes group-chat member access where per-user allow/deny lists previously never matched the group principal).
+- `internal/tools/team_tool_dispatch.go`: teammate-dispatch metadata now carries `MetaOriginSenderID` so the teammate's turn has the original user's sender.
+- `internal/tools/sessions_send.go`: session_send metadata now carries `MetaOriginSenderID` to preserve user identity across agent-to-agent flows.
+
+#### Scope-intentional (unchanged, commented)
+
+- `internal/tools/cron.go`: cron jobs remain per-group-scope (memory-model parity; migrating would break collaborative `/cron list/add/remove`).
+- `internal/tools/team_tasks_create.go`: team task `UserID` remains per-group (team visibility is per-chat, not per-user).
+
+#### Tests
+
+- New `tests/integration/telegram_group_write_file_permission_test.go` — 9 sub-tests covering granted-sender, ungranted-sender, no-agent fail-open branch, DM no-op, `|`-delimited sender, empty-sender deny, synthetic-prefix deny (7 sub-cases), propagated-sender allow, DM empty-sender passes.
+- Regression coverage for both the user-reported denial (#915 BUG-B) and the silent-bypass (#915 BUG-A).
+
+#### Notes
+
+- No DB migration shipped: historical `skills.owner_id` rows that were created with a `group:*` / `guild:*` value remain accessible via the patch/delete legacy fallback. Re-publishing a skill transfers ownership to the individual actor.
+- Audit report: `plans/reports/audit-260416-1240-actor-scope-comprehensive.md`.

+## [Unreleased] — 2026-04-15
+
+#### Agent Hooks System — Phase 3: Prompt Handler + Web UI (2026-04-15)
+
+Third handler type (`prompt`) with full cost safeguards, WS RPC surface, complete Web UI, 3-language i18n, and production wiring. Closes Issue #875 feature parity with Claude-Code-style hooks.
+
+### Added
+- **`internal/hooks/handlers/prompt.go`**: LLM hook handler with structured tool-call output (`decide` tool), anti-injection system preamble, fenced user-input delimiter, in-memory decision cache (60s TTL keyed by `sha256(hook_id||version||tool_name||tool_input)`), per-turn invocation cap (default 5), provider resolver abstraction
+- **`internal/hooks/handlers/prompt_resolver.go`**: `RegistryResolver` maps model aliases (haiku/sonnet/opus, gpt-*, gemini-*, qwen-*) to tenant providers; falls back to system configs (`hooks.prompt.provider`, `background.provider`) then first registered
+- **`internal/hooks/budget/` package**: `Store` + `Dialect` interface for atomic per-tenant monthly token budget deduction; `ShouldWarn` helper at 20% threshold
+- **Budget store implementations**: `pg.PGHookBudget` (single UPDATE + RETURNING with UPSERT seed on month rollover) and `sqlitestore.SqliteHookBudget` (tx-wrapped equivalent)
+- **WS RPC methods** (`internal/gateway/methods/hooks.go`): `hooks.list` (viewer+), `hooks.create`/`update`/`delete`/`toggle` (admin+, master-scope for global), `hooks.test` (operator+, dryRun no audit write), `hooks.history` (viewer+, stub pending phase 4 pagination)
+- **Protocol constants**: `MethodHooksList/Create/Update/Delete/Toggle/Test/History` in `pkg/protocol/methods.go`
+- **Web UI `/hooks` page**: single route with `useParams().id` — list view when no id, detail view when present (CLAUDE.md "route params as source of truth"). Tabs: Overview | Config | Test | History
+- **Web UI components**: `hook-list-row`, `hook-form-dialog` (3 sub-forms per handler type; command radio disabled on Standard with tooltip), `hook-test-panel` (fires `dryRun=true`, decision badge + duration + stdout/stderr/status), `hook-diff-viewer` (side-by-side JSON diff via highlight.js), `hook-history-table`, `hook-overview-tab`
+- **Zod + TanStack Query**: `schemas/hooks.schema.ts` (prompt requires matcher|if_expr + prompt_template), `hooks/use-hooks.ts` (useHooksList/Hook/CreateHook/UpdateHook/DeleteHook/ToggleHook/TestHook/HookHistory)
+- **i18n backend**: 6 new keys (`hook.invalid_matcher`, `hook.command_disabled_standard`, `hook.prompt_requires_matcher`, `hook.circuit_breaker_tripped`, `hook.budget_exceeded`, `hook.per_turn_cap_reached`) in en/vi/zh catalogs
+- **i18n UI**: `ui/web/src/i18n/locales/{en,vi,zh}/hooks.json` with identical key ordering (per CLAUDE.md memory rule)
+- **Production wiring**: `cmd/gateway_managed.go` registers `HandlerPrompt` in dispatcher handlers map; `cmd/gateway.go` registers `HookMethods` in router
+- **Sidebar nav**: "Hooks" entry with `Webhook` icon in Capabilities group
+
+### Security / cost safeguards
+- **Structured output enforcement**: evaluator MUST call the `decide` tool; free-text responses fail-closed to block
+- **Sanitized input**: only `tool_input` reaches the evaluator inside a fenced `USER INPUT` block; raw user message never included
+- **Injection detection flag**: evaluator can signal `injection_detected=true` via structured output
+- **Version-busted cache**: hook config edits bump `version` → cache key changes → forces re-evaluation
+- **Atomic budget deduct**: no select-then-update race (L2 mitigation)
+
+### Testing
+- **Unit**: `prompt_test.go` (14 tests — cache hit/miss, version bust, per-turn cap, fail-closed paths, schema assertions), `prompt_injection_test.go` (4 tests — hostile inputs, unicode homoglyphs, nested JSON, fenced delimiter integrity), `budget_test.go` (9 tests — atomic deduct, exceed-returns-err, month rollover, zero-cost, nil tenant, warn threshold)
+- **WS RPC unit**: `gateway/methods/hooks_test.go` (param parsing + HookTestResult struct round-trip)
+- **UI**: 56/56 vitest passing including 20 new hook-specific tests (schema validation, list rendering, test panel, diff viewer, i18n contracts)
+
+#### Agent Hooks System — Phase 4: Hardening + Docs (2026-04-15)
+
+Integration / chaos / RBAC / tracing coverage + user documentation + copy-paste example hooks library. Merge gate.
+
+### Added
+- **Integration tests** (`tests/integration/hooks_e2e_test.go`): 7 events × HTTP/command handler coverage, tenant isolation (cross-tenant events don't hit other tenants' hooks), context-update injection path, edition gate at dispatch time
+- **Chaos tests** (`hooks_chaos_test.go`): provider down (fail-closed block on blocking event), per-hook timeout respected, circuit breaker auto-disables after 3 consecutive blocks and persists `enabled=false`, `ErrLoopDepthExceeded` when depth > `MaxLoopDepth` (M5), `dedup_key` unique index suppresses double audit rows on retry (H6), 5xx retry-once-then-error
+- **RBAC tests** (`hooks_rbac_test.go`): store tenant isolation (List/Get/Update/Delete all respect tenant_id), global-scope visible to all tenants, ResolveForEvent unions tenant + global hooks, `HasMinRole` matrix over the hooks.* method surface
+- **Tracing tests** (`hooks_tracing_test.go`): `EmitHookSpan` writes row with canonical name `hook.<handler_type>.<event>`; dispatcher + traced-handler wrapper emits spans end-to-end
+- **User docs** `docs/agent-hooks.md`: concepts, security model, handler reference, matcher guide, safeguard table, Web UI walkthrough, observability (audit table + tracing spans + slog keys), troubleshooting, migration notes, known limitations
+- **Example library** `examples/hooks/`: `block-rm-rf.json` (command, Lite), `auto-lint-after-write.json` (http async), `audit-tool-usage.json` (tenant-wide audit), `session-context-injector.json` (context bootstrap), `notify-discord-on-stop.json` (webhook notification), `README.md` with safety guidance
+
+### Fixed
+- **`PGHookStore.GetByID` + `SqliteHookStore.GetByID`** now enforce tenant scope: non-master callers only see own + global rows. Previously returned any row by UUID which leaked cross-tenant.
+- **Existing pipeline integration tests** now call `security.SetAllowLoopbackForTest(true)` via shared helper; no longer flake on SSRF block for httptest endpoints.
+- **Vault**: Shared docs (`scope='shared'`, `agent_id=NULL`) are now visible to agents via `vault_search`, `ListDocuments`, `CountDocuments`. Previously excluded by strict `agent_id = $N` predicate after migration 000046 made `agent_id` nullable. Also fixes single-team filter to include shared docs. Adds CHECK invariant (migration 000055) to prevent future scope/ownership drift. Affects PostgreSQL and SQLite (desktop edition). (#917)
+
+### Testing
+- All hook integration tests pass under `TEST_DATABASE_URL` PG container (7 new test files, 18 new top-level tests)
+- `go build` + `go build -tags sqliteonly` + `go vet` clean
+- `pnpm test` 56/56 pass
+- Race detector clean for `internal/hooks/...` + `internal/gateway/methods/`
+
+### Deferred (post-MVP)
+- Cluster-wide prompt decision cache via Redis
+- Skill-frontmatter hooks
+- `agent` handler type (inter-agent delegation via prompt instead)
+- Desktop Wails UI parity for hooks page
+- Load/throughput benchmarks (explicitly dropped from Phase 4 scope)
+
+---
+
+#### Agent Hooks System — Phase 1: Foundation (2026-04-15)
+
+Lifecycle hook infrastructure: event dispatcher (sync/async paths), audit logging, database schema (PostgreSQL + SQLite), store interface, config validation, edition gating. Handlers + pipeline integration deferred to Phase 2.
+
+### Added
+- **`internal/hooks/` package**: Foundational types (HookConfig, HookExecution, Event), StdDispatcher (fire-and-decide with sequential execution), CEL+regex matcher, audit writer (PII-redacted, encrypted), circuit breaker with auto-disable
+- **PostgreSQL migration 000052**: `agent_hooks` table (id, tenant_id, agent_id, event, handler_type, config, matcher, if_expr, priority, enabled, created_at, updated_at) + `hook_executions` table (hook_id, session_id, event, input_hash, decision, duration_ms, error, created_at) with unique dedup_key index
+- **SQLite schema entries**: Full schema in `schema.sql` + migration map bump for Lite/desktop edition
+- **HookStore interface + implementations**: `PGHookStore` (database/sql + pgx/v5) and `SQLiteHookStore` (modernc.org/sqlite) with List, Create, Update, Delete, LogExecution methods
+- **Security primitives**: Loop-depth guard (M5 mitigation, MaxLoopDepth=3), per-hook timeout, chain budget (10s wall-time), circuit breaker with auto-disable (C4 mitigation), fail-closed policy for blocking events
+- **Edition gating**: `HookEditionPolicy` allows command handler on Lite only; master-scope blocks command on Standard tenant
+- **Config validation**: CEL cost limits, required matcher for prompt handlers, bounded queue per-turn limits
+
+### Changed
+- **Store layer**: Added `store.Hooks` field (typed as `any` to avoid import cycles)
+- **Base store**: `TablesWithUpdatedAt["agent_hooks"] = true` for touch-all update helpers
+
+### Testing
+- **Integration test suite**: `tests/integration/v3_hooks_store_test.go` covers multi-tenant isolation, dedup key uniqueness, schema migration up/down for both PG + SQLite
+
+### Deferred to Phase 3+
+- Prompt handler (modifies input/context dynamically)
+- Web UI (CRUD, test panel, history)
+- Tracing integration
+- i18n keys (en/vi/zh)
+
+---
+
+#### Agent Hooks System — Phase 2: Handlers + Pipeline Integration (2026-04-15)
+
+Concrete handler implementations + pipeline wiring. Command handler (shell, Lite-only), HTTP handler (SSRF-hardened), synced at ContextStage/ToolStage/FinalizeStage, async at SessionStart/PostToolUse/Stop, delegate bridging (SubagentStart/SubagentStop).
+
+### Added
+- **`internal/hooks/handlers/` package**: `CommandHandler` (exec wrapper, JSON I/O, env allowlist, edition policy recheck), `HTTPHandler` (SSRF-hardened HTTP client, retry-once on 5xx, 4xx error no-retry, response parsing for decision/context/updatedInput)
+- **Pipeline dispatcher integration**: `PipelineDeps.HookDispatcher` field (nil-safe noop fallback); stages call `deps.Hooks.Fire(ctx, evt)` at: ContextStage (SessionStart async + UserPromptSubmit sync), ToolStage (PreToolUse sync before exec + PostToolUse async), FinalizeStage (Stop async)
+- **Copy-on-write staging**: UserPromptSubmit + PreToolUse updatedInput buffered per-call; commit only when ALL sync hooks succeed; rejection/timeout discards buffer (H2)
+- **Delegate event bridge**: `delegate_bridge.go` subscribes DelegateCompleted/DelegateFailed events from domain bus, fires SubagentStop async; SubagentStart sync fired directly in delegate_tool pre-call
+- **Command handler edition gating**: Re-checks `HookEditionPolicy` at dispatch (defense-in-depth); Lite-only with master-scope block on Standard tenant
+- **HTTP handler SSRF hardening**: Uses caller-supplied net.Dialer that pins resolved IP, blocks loopback/link-local/private ranges; auth headers (e.g. Authorization) encrypted at rest in cfg.Config["headers"], decrypted only at send-time; no redirects allowed (CheckRedirect returns ErrUseLastResponse)
+- **Server wiring**: `cmd/gateway_managed.go` constructs `hooks.NewStdDispatcher` with both handlers registered; passes dispatcher through `agent.ResolverDeps.HookDispatcher` and `delegateTool.SetHookDispatcher(...)`; falls back to `hooks.NewNoopDispatcher()` when `stores.Hooks` is nil
+- **Encryption key handling**: Reads `GOCLAW_ENCRYPTION_KEY` env for HTTP handler header decryption; optional (empty → no decryption)
+
+### Testing
+- **Unit tests**: `internal/hooks/handlers/command_test.go` (8 tests — exit codes, timeout, env allowlist, edition gate, ctx cancel), `http_test.go` (9 tests — response parsing, retry logic, SSRF blocking pre+post DNS, no redirects, auth header security)
+- **Integration tests**: `tests/integration/hooks_pipeline_test.go` (4 tests — SessionStart async, UserPromptSubmit block + context + updatedInput COW, PreToolUse block + args mutation, PostToolUse async, zero-overhead no-hooks path); `tests/integration/hooks_delegate_test.go` — SubagentStart/Stop with loop-depth guard M5
+
+### Changed
+- **Pipeline architecture**: 8-stage loop now fires hooks via `PipelineDeps.Dispatcher`; stage callbacks support nil-safe dispatcher (noop when not configured)
+- **Delegate tool**: `delegateTool.SetHookDispatcher(...)` enables async SubagentStop via existing domain events
+
+---
+
+#### Desktop Voice Management + STT Admin (2026-04-15)
+
+### Added
+- **Desktop voice picker**: Agent detail panel now includes a voice selector with live preview. Users can browse ElevenLabs voices, hear a sample, and persist the choice per agent on the desktop app.
+- **Desktop STT admin form**: Speech-to-text provider configuration (API keys, providers, WhatsApp opt-in toggle + privacy banner) available in desktop tool settings.
+- **Singleton voice preview**: Only one voice sample plays at a time; preview button hides automatically when a voice has no sample URL.
+- **Desktop i18n `tts` namespace**: Voice-management strings translated to English, Vietnamese, and Chinese; STT form labels added to the tools namespace.
+- **Desktop test harness**: Vitest + Testing Library infrastructure; voice picker and STT form covered by unit tests.
+
+### Changed
+- **Agent voice persistence (desktop)**: Voice selection merges into `other_config` without overwriting sibling fields.
+- **Tool settings routing (desktop)**: Speech-to-text tool opens the dedicated admin form instead of the generic JSON editor.
+
+---
+
+#### ElevenLabs Audio Manager Refactor — Phase 5 (2026-04-15)
+
+Channel STT migration (Telegram/Feishu/Discord) + WhatsApp voice transcription with tenant opt-in (default disabled due to E2E encryption trade-off, resolves privacy red-team finding).
+
+### Added
+- **WhatsApp voice transcription**: `internal/channels/whatsapp/stt.go` — opt-in per-tenant via `builtin_tools[stt].settings.whatsapp_enabled` (default `false` per Decision 6)
+- **Synchronous 10s timeout**: All 4 channels (Telegram/Feishu/Discord/WhatsApp) enforce ctx timeout for voice message processing; timeout/error → fallback label
+- **i18n fallback key**: `MsgVoiceMessageFallback` ("voice message" placeholder in en/vi/zh) rendered when STT unavailable or disabled
+- **Privacy banner**: Admin UI displays E2E encryption trade-off warning when enabling WhatsApp STT
+
+### Changed
+- **Channel STT handlers**: All 4 channels now call `audio.Manager.Transcribe()` with 10s timeout instead of per-channel `transcribeAudio()` helpers
+- **Channel factory signatures**: All 4 factories (`NewChannel`) accept `audioMgr *audio.Manager` parameter
+- **WhatsApp messaging**: Voice messages now transcribed (opt-in) and appended to message text for agent understanding
+
+### Removed
+- **Per-channel STT helpers**: Deleted `internal/channels/{telegram,feishu,discord}/stt.go` (consolidated into Manager)
+- **Telegram STT tests**: Deleted `internal/channels/telegram/stt_test.go` — coverage preserved in `internal/audio/proxy_stt/provider_test.go` (12 ported scenarios, deliberate deletion documented)
+
+### Resolved
+- **Audit finding P5-B1**: Gate G4 verified; Manager.Transcribe chain wired
+- **Audit finding P5-H1**: All transcribeAudio call sites migrated; grep confirms zero direct channel STT calls
+- **Audit finding P5-H2** + **Decision 6** (privacy): WhatsApp STT opt-in with default=false; privacy banner + docs note E2E trade-off
+- **Cross-phase XP-3**: Telegram test ported/deleted with 12-scenario coverage guarantee
+- **Cross-phase XP-4**: `MsgVoiceMessageFallback` pre-wired in Phase 5 step 1 (blocking)
+
+### Security / Privacy
+- **WhatsApp E2E encryption**: Voice transcription breaks end-to-end guarantee. **Tenant opt-in required** with explicit admin acknowledgment (privacy banner in UI)
+- **Temp file cleanup**: Existing `scheduleMediaCleanup` preserves file handles during 10s STT window; no race condition risk
+- **Audit logging**: WhatsApp STT invocation logged at info level for audit trail
+
+---
+
+#### ElevenLabs Audio Manager Refactor — Phase 4 (2026-04-15)
+
+STT via ElevenLabs Scribe + proxy fallback with tenant config migration + admin UI form. Legacy per-channel STT config bridged with 2-week deprecation grace.
+
+### Added
+- **ElevenLabs Scribe STT provider**: `internal/audio/elevenlabs/stt.go` — POST `/v1/speech-to-text`, multipart upload, 20MB cap, configurable language + diarization
+- **Proxy STT wrapper**: `internal/audio/proxy_stt/provider.go` — backward-compat bridge for legacy `media.TranscribeAudio` with automatic temp-file handling
+- **STT admin form**: `ui/web/src/pages/builtin-tools/stt-provider-form.tsx` — mirrors TTS form pattern, includes tenant config (API keys, providers list, WhatsApp opt-in toggle)
+- **`audio.Manager.Transcribe()`**: Chain-based STT dispatch with channel-override precedence (per-channel STTProxyURL wins over tenant builtin_tools[stt])
+- **i18n keys**: `MsgSTTAllProvidersFailed`, `MsgSTTLegacyConfigDeprecated`, `MsgSTTWhatsappPrivacyWarning` across en/vi/zh
+
+### Changed
+- **STT config location**: Migrated from per-channel fields (Telegram/Feishu/Discord `STTProxyURL`) to tenant `builtin_tools[stt].settings` (Decision 1 per audit)
+- **`builtin_tools[stt]` table entry**: New seed row via migration 000050 (PG) + schema.go incremental (SQLite)
+- **Legacy bridge**: Startup-time scan of per-channel STT configs → auto-registers `proxy_stt.Provider` with deprecation warn when tenant lacks `builtin_tools[stt]` (2-week grace period)
+
+### Resolved
+- **Audit finding P4-H1** (channel-override precedence): Decision 2 — per-channel config takes priority; tenant fallback when channel config absent
+- **Audit finding P4-H2** (Scribe endpoint verification): ElevenLabs Scribe v2 `/v1/speech-to-text` confirmed with xi-api-key auth
+- **Audit finding P4-B3** (explicit bridge loop): 3-channel explicit loop (Telegram, Feishu, Discord) replaces ambiguous iteration
+- **Cross-phase XP-3** (12 test ported): All 12 Telegram STT scenarios (NoProxy, EmptyFile, Success, Error, etc.) ported into `proxy_stt/provider_test.go` before Phase 5 channel migration
+
+### Deprecated
+- Per-channel `STTProxyURL`, `STTAPIKey`, `STTTenantID` fields (Telegram, Feishu, Discord configs) — soft deprecation with 2-week grace; migration to `builtin_tools[stt]` required for Phase 5+ channels
+
+### Fixed
+- **JSON schema divergence**: `duration_secs` → `audio_duration_secs` in Scribe response parsing (matches ElevenLabs API)
+- **Provider registration**: Scribe + SetSTTChain wired into setupAudioExtras for Phase 5 channel integration
+
+---
+
+#### ElevenLabs Audio Manager Refactor — Phase 3 (2026-04-14)
+
+Music generation via ElevenLabs + MiniMax with fallback chain. Suno provider fully removed from codebase (no official API, ToS violation risk).
+
+### Added
+- **ElevenLabs Music provider**: `internal/audio/elevenlabs/music.go` — POST `/v1/music`, model `music_v1`, binary MP3 response, 300s timeout, prompt + optional lyrics
+- **MiniMax Music provider**: `internal/audio/minimax/music.go` — POST `{base}/music_generation`, 2-step URL-download pattern, 200 MB cap, optional instrumentation toggle
+
+### Changed
+- **`create_audio` tool simplified**: Now thin Manager dispatcher (`NewCreateAudioTool(audioMgr *audio.Manager)`), removed inline provider logic + per-provider switch cases
+- **`audio.Manager.GenerateMusic/GenerateSFX`**: Chain-based resolution (elevenlabs → minimax for music, elevenlabs-only for SFX)
+- **`createAudio` builtin tool**: Unified dispatch via Manager instead of `providers.Registry` dependency injection
+
+### Removed
+- **Suno provider**: Fully excised (10 atomic locations) — research confirms no official API + ToS violations. Files deleted: `create_audio_suno.go`, `create_audio_minimax.go`, `create_audio_elevenlabs.go` shim. HTTP route removed. TS schema entry removed. Config provider removed.
+
+### Types
+- **`audio.MusicOptions`**: Added `Instrumental bool`, `Model string`, `TimeoutSec int` fields
+- **`audio.AudioResult`**: Added `Provider string` field for observability (tool span metadata)

 ## [Unreleased]
 
+### Added
+
+#### ElevenLabs Audio Manager Refactor — Phase 1 (2026-04-14)
+
+Unified audio provider management via new `internal/audio/` package with pluggable interface-based architecture. Phase 1 wires TTS providers (ElevenLabs, OpenAI, Edge, MiniMax); STT/Music/SFX interfaces defined for Phase 3-4.
+
+**What changed:**
+- **`internal/audio/` package**: Central `Manager` orchestrates 4 provider kinds via interfaces (`TTSProvider`, `STTProvider`, `MusicProvider`, `SFXProvider`)
+- **Provider organization**: Implementations in `internal/audio/{elevenlabs,openai,edge,minimax}/`. ElevenLabs shared HTTP client (`xi-api-key` header) for both TTS and SFX subproviders
+- **`internal/tts/` → backward-compat alias**: 24-symbol package (15 types + 6 consts + 5 constructors + 5 signature guards). All pre-refactor callers compile unchanged, zero breaking changes
+- **Config extension**: `config.Audio` optional pointer (nil-safe) added for future STT/Music subsections. `cfg.Tts` retained unchanged
+- **ElevenLabs SFX tool**: `internal/tools/create_audio_elevenlabs.go` rewritten as thin shim calling `elevenlabs.NewSFXProvider(...).GenerateSFX(ctx, audio.SFXOptions{...})`
+- **WS `tts.*` namespace**: 6 methods unchanged externally
+
+**Impact**: Existing TTS flows fully compatible. New code can import `internal/audio` directly. STT/Music/SFX wiring deferred to Phase 3-4.
+
+#### ElevenLabs Audio Manager Enhancements — Phase 2 (2026-04-14)
+
+Voice discovery and agent-level audio config via new backend endpoints, in-memory cache, and web UI picker. Bundles producer/consumer context pattern (`store.WithAgentAudio`) for seamless voice/model resolution throughout the tool execution pipeline.
+
+**What changed:**
+- **Voice cache** (`internal/audio/voice_cache.go`): In-memory LRU (cap 1000 tenants) with TTL 1h, shared between HTTP + WS handlers, thread-safe under concurrent access
+- **Streaming TTS interface** (`internal/audio/types.go`): New `StreamingTTSProvider` optional interface for ElevenLabs `/v1/text-to-speech/{voice_id}/stream` chunked playback
+- **ElevenLabs enhancements**: Model allowlist (11_v3, eleven_flash_v2_5, eleven_multilingual_v2, eleven_turbo_v2_5), `SynthesizeStream()` method, `ListVoices()` via `/v1/voices`
+- **Agent audio context** (`internal/store/context.go`): New `WithAgentAudio` / `AgentAudioFromCtx` bundle; producer wires snapshot at dispatcher level (internal/agent/), consumer (`TtsTool.Execute`) reads voice/model overrides from agent config
+- **Agent config extension** (`agents.other_config` JSONB): New `tts_voice_id` and `tts_model_id` fields with resolution precedence: args → agent → tenant → provider default
+- **HTTP + WS endpoints**: GET /v1/voices (cached), POST /v1/voices/refresh (admin-only), WS method `voices.list` + `voices.refresh`
+- **Web voice picker** (`ui/web/src/components/voice-picker.tsx`): Combobox with search, preview button (HTML audio + onError → refresh), embedded in PromptSettingsSection
+- **i18n**: 10 new frontend keys (voice_label, voice_placeholder, voice_refresh, voice_preview, model_label, etc.) + 2 new backend keys (MsgTtsUnknownModel, MsgVoicesListFailed) across en/vi/zh
+
+**Impact**: Existing TTS callers fully compatible (backward-compat via Phase 1 alias layer). Web UI gains voice discovery + per-agent voice/model overrides. Zero breaking changes. Integration test validates producer+consumer context flow.
+
+#### Trace Stop/Abort Redesign — Cascading 4-Layer Fix (2026-04-14)
+
+The Stop button on the traces page now reliably aborts running traces. Previous implementation had independent race conditions across HTTP streaming, agent router, trace persistence, and UI polling; this redesign fixes all four layers atomically.
+
+**What changed:**
+- **HTTP streaming ctx-aware**: Provider clients use transport-level `ResponseHeaderTimeout` + `IdleConnTimeout` instead of socket-level `Client.Timeout`. SSE body closes immediately on ctx cancel via goroutine-based wrapper (prevents 5-minute socket block).
+- **Router 2-phase abort**: `AbortRun()` atomically transitions to aborting state, waits 3s for goroutine exit via `Done` channel, then force-marks trace `cancelled` if timeout. No orphaned goroutines, no "not found" race.
+- **Trace status persistence**: `SetTraceStatus()` detached from request context with 5s timeout, 3-try exponential backoff, and bounded in-memory retry queue (10 max tries). Stale recovery worker runs every 30s, catches zombie traces in 2 minutes instead of 30.
+- **Real-time UI updates**: New WS event `trace.status` broadcasts status changes immediately after persist succeeds. UI drops 60s polling interval, subscribes to events instead.
+- **Tool execution audit**: Shell commands use process-group kill (`SIGTERM`→3s→`SIGKILL`). Browser automation (Rod) closes pages on ctx cancel. MCP delegates timeout after 5s.
+- **i18n**: 6 abort toast variants (success/timeout/not-found/already-done/db-error/unknown) + translations for en/vi/zh.
+
+**Impact**: Existing traces and sessions unaffected. UI now reflects backend state accurately. Zero breaking changes.
+
+#### Preserve User-Provided Filenames for Media Uploads (2026-04-14)
+
+Filenames provided by users for chat media uploads now survive the channel adapter → agent → disk persistence round trip, enabling vault enrichment to process human-readable document names instead of falling back to generic UUID-only storage.
+
+**Why**: Vault enrichment was skipping UUID-only disk names (design safety to avoid noisy auto-generated files), causing documents with Vietnamese or CJK stems to remain unenriched and lose semantic context.
+
+**What changed**:
+- **`bus.MediaFile.Filename` field**: Channel adapters now populate this field when source provides original filename (e.g., user-selected file upload, Telegram file_name, WhatsApp display_name)
+- **Sanitizer** (`internal/agent/media_filename.go`): Derives safe stems via `sanitizeFilename()` with:
+  - **Vietnamese pre-NFD map**: `đ/Đ → d` (Unicode NFD does not decompose these precomposed letters)
+  - **CJK passthrough**: Dominant-script heuristic detects Vietnamese/CJK inputs and preserves original runes (no ASCII slugification)
+  - **Filesystem safety**: Removes control chars, path traversal markers (`..`, `/`, `\\`), and reserved names
+  - **Max length**: 60 runes (script-aware, not byte-based) to avoid platform path limits
+- **Disk naming scheme**: `{sanitized-stem}-{8hex}{ext}` (e.g., `bao-cao-q4-a1b2c3d4.pdf`) when sanitizer returns non-empty stem; UUID fallback `{uuid}{ext}` for empty stems (voice notes, clipboard pastes, tool-generated media)
+- **Vault enrichment gating** (`internal/vault/enrich_skip_filter.go`): Now skips UUID-only filenames (matching `^[0-9a-f]{8}-...$` pattern) while processing named stems
+- **6 channel adapters wired**: Telegram, Slack, Discord, Feishu/Lark, Zalo OA, WhatsApp all set `MediaFile.Filename` when available
+- **Tools + orchestration**: `web_search` tool (PDF downloads), delegate/subagent media propagation, all preserve filenames end-to-end
+
+**Impact**: Existing flows with empty `Filename` are unaffected (UUID-named as before). New flows with filenames produce human-readable, enrichable disk names. Zero breaking changes.

 ### Fixed
 
+#### Pancake Platform Field — Mandatory Select (2026-04-14)
+
+- **`platform` field changed from optional text to required dropdown**: `channel-schemas.ts` replaces the free-text `platform` field with a `select` type (11 options: facebook, instagram, threads, tiktok, youtube, shopee, line, google, chat_plugin, lazada, tokopedia). `required: true` is now enforced by the form dialog on create.
+- **Config required-field validation (create-only)**: `channel-instance-form-dialog.tsx` now enforces `required` on config fields at submit time. Validation is scoped to create flows only — edit flows are unchanged to avoid silent breakage on existing channels with no stored `platform`.
+- **i18n**: Platform field label options and config field metadata added to `channels.json` for en/vi/zh.
+- **Auto-detect log level**: `pancake.go` auto-detect block demoted from `slog.Info` to `slog.Debug` to stop log noise on every channel start; auto-detect remains as a fallback for existing channels with no stored `platform`.
+
 #### Feishu/Lark Writer Management Commands — Issue #818 Closed (2026-04-11)
 - **Issue #818 resolution**: Closes UX gap where users saw `/addwriter` error messages but Feishu had no handler
 - **Phase 1 — Thread reply routing**: Inbound messages with `thread_id` now properly route responses back to the same Feishu thread via `/open-apis/im/v1/messages/{id}/reply`. New `feishu_reply_target_id` metadata key included in `routingMetaKeys` allowlist. Graceful fallback to `SendMessage()` if thread root deleted

+# Agent Hooks
+
+Lifecycle hooks let you intercept, observe, or inject behavior at defined points in the agent loop. Use cases: block unsafe tool calls, auto-lint after writes, inject session context, notify on stop, audit tool usage.
+
+## Concepts
+
+### Events
+Seven lifecycle events fire during an agent session:
+
+| Event | Blocking | When it fires |
+|---|---|---|
+| `session_start` | no | A new session is established. |
+| `user_prompt_submit` | **yes** | Before the user's message enters the pipeline. |
+| `pre_tool_use` | **yes** | Before any tool call executes. |
+| `post_tool_use` | no | After a tool call completes. |
+| `stop` | no | The agent session terminates normally. |
+| `subagent_start` | **yes** | A sub-agent is spawned. |
+| `subagent_stop` | no | A sub-agent finishes. |
+
+Blocking events wait for the sync chain to return an allow/block decision. Non-blocking events fire hooks asynchronously for observation only.
+
+### Handler types
+
+| Handler | Editions | Notes |
+|---|---|---|
+| `command` | Lite only | Local shell command; exit 2 → block, exit 0 → allow. |
+| `http` | Lite + Standard | POST to endpoint; JSON body → decision. SSRF-protected. |
+| `prompt` | Lite + Standard | LLM-based evaluation with structured tool-call output. Prompt-injection-resistant, budget-bounded. Requires `matcher` or `if_expr`. |
+
+### Scopes
+- **global** — applies to all tenants. Master scope required to create.
+- **tenant** — applies to one tenant (any agent).
+- **agent** — applies to a specific agent within a tenant.
+
+Hooks resolve in priority order, highest first. A single `block` decision short-circuits the chain.
+
+## Security model
+
+- **Edition gating**: `command` handler blocked on Standard at both config-time AND dispatch-time (defense in depth).
+- **Tenant isolation**: all reads/writes scope by `tenant_id` unless caller is in master scope. Global hooks use a sentinel tenant id.
+- **SSRF protection**: HTTP handler validates URLs before request, pins resolved IP, blocks loopback/link-local/private ranges.
+- **PII redaction**: audit rows truncate error text to 256 chars; full error is encrypted (AES-256-GCM) in `error_detail`.
+- **Fail-closed**: any unhandled error in a blocking event yields `block`. Timeouts respect `OnTimeout` (default `block` for blocking events).
+- **Circuit breaker**: N consecutive blocks/timeouts in a rolling window auto-disables the hook and persists `enabled=false`.
+- **Loop detection**: sub-agent hook chains bounded at depth 3 (`MaxLoopDepth`).
+
+## Handler reference
+
+### command
+
+```json
+{
+  "handler_type": "command",
+  "config": {
+    "command": "bash /path/to/script.sh",
+    "allowed_env_vars": ["MY_VAR"],
+    "cwd": "/workspace"
+  }
+}
+```
+
+- Stdin: JSON-encoded event payload.
+- Stdout (exit 0): optional `{"continue": false}` → block; anything else → allow.
+- Exit 2: block.
+- Other non-zero exits: error (fail-closed for blocking events).
+- Env allowlist: only listed keys are passed through to prevent secret leakage.
+
+### http
+
+```json
+{
+  "handler_type": "http",
+  "config": {
+    "url": "https://example.com/webhook",
+    "headers": {"Authorization": "<AES-encrypted>"}
+  }
+}
+```
+
+- Method: POST, body = event JSON.
+- Authorization header values are stored AES-256-GCM encrypted; decrypted at dispatch.
+- 1 MiB response cap.
+- Retries once on 5xx with 1s backoff; 4xx fail-closed (no retry).
+- Response body:
+  ```json
+  { "decision": "allow" | "block", "additionalContext": "...", "updatedInput": {}, "continue": true }
+  ```
+- Non-JSON 2xx → allow.
+
+### prompt
+
+```json
+{
+  "handler_type": "prompt",
+  "matcher": "^(exec|shell|write_file)$",
+  "config": {
+    "prompt_template": "Evaluate safety of this tool call.",
+    "model": "haiku",
+    "max_invocations_per_turn": 5
+  }
+}
+```
+
+Required:
+- `prompt_template` — system-level instruction the evaluator receives.
+- `matcher` or `if_expr` — runaway-cost guard; prevents firing the LLM on every event.
+
+Safeguards:
+- **Structured output**: evaluator MUST call a `decide(decision, reason, injection_detected, updated_input)` tool. Free-text responses fail-closed.
+- **Sanitized input**: only `tool_input` reaches the evaluator (sandwiched in a fenced `USER INPUT` block with anti-injection preamble); the raw user message is never included.
+- **Decision cache**: 60s TTL keyed by `sha256(hook_id || version || tool_name || tool_input)`. Hook edits bump version → busts cache.
+- **Per-turn cap**: default 5 invocations per user turn; configurable.
+- **Per-tenant monthly budget**: atomic UPDATE deduct; warn at 20% remaining, block at 0.
+
+## Matchers
+
+- **matcher** — POSIX-ish regex applied to `tool_name`. Example: `^(exec|shell|write_file)$`.
+- **if_expr** — [cel-go](https://github.com/google/cel-go) expression evaluated against `{tool_name, tool_input, depth}`. Example: `tool_name == "exec" && size(tool_input.cmd) > 80`.
+
+Both are optional for `command` / `http`. At least one is required for `prompt`.
+
+## Safeguards summary
+
+| Safeguard | Default | Overridable per hook |
+|---|---|---|
+| Per-hook timeout | 5s | yes (`timeout_ms`, max 10s) |
+| Chain budget | 10s | no (dispatcher constant) |
+| Circuit threshold | 5 blocks in 1 minute | no (dispatcher constant) |
+| Prompt per-turn cap | 5 | yes (`max_invocations_per_turn`) |
+| Prompt decision cache TTL | 60s | no |
+| Tenant monthly token budget | 1,000,000 | seeded per tenant |
+
+## Web UI walkthrough
+
+Navigate to **Hooks** in the sidebar. The list view shows all hooks visible under the current role + tenant scope.
+
+1. **Create** → pick event, handler type (command disabled on Standard), scope, matcher, then fill the handler-specific sub-form.
+2. **Test** panel → fires the hook with a sample event (`dryRun=true`, no audit row written). Shows decision badge, duration, stdout/stderr (command), status code (http), reason (prompt). If the response includes `updatedInput`, a side-by-side JSON diff is rendered.
+3. **History** tab → paginated executions from `hook_executions` (full implementation lands with operational pagination; current release shows the note state).
+4. **Overview** tab → summary card with event, type, scope, matcher.
+
+## Observability
+
+### Audit table (`hook_executions`)
+
+| Column | Notes |
+|---|---|
+| `hook_id` | `ON DELETE SET NULL` → executions preserved after hook deletion. |
+| `dedup_key` | Unique index prevents double rows on retry (H6). |
+| `error` | Truncated to 256 chars; full detail in `error_detail` (encrypted). |
+| `metadata` | JSONB: `matcher_matched`, `cel_eval_result`, `stdout_len`, `http_status`, `prompt_model`, `prompt_tokens`, `trace_id`. |
+
+### Tracing spans
+
+Every hook execution emits a span named `hook.<handler_type>.<event>` (e.g. `hook.prompt.pre_tool_use`) with:
+
+- `status` — `completed` or `error`.
+- `duration_ms`.
+- `metadata.decision` — `allow`/`block`/`error`/`timeout`.
+- `parent_span_id` — nested under the current pipeline span when one exists.
+
+No-op when no tracing collector is attached to ctx (safe in tests and for tenants without tracing enabled).
+
+### Metrics (slog keys)
+
+- `security.hook.circuit_breaker` — tripped breaker.
+- `security.hook.audit_write_failed` — audit row write error.
+- `security.hook.resolve_error` — store resolve error (blocking event → fail-closed).
+- `security.hook.loop_depth_exceeded` — `MaxLoopDepth` violation.
+- `security.hook.prompt_parse_error` — evaluator returned malformed structured output.
+- `security.hook.budget_deduct_failed` / `budget_precheck_failed` — budget store error.
+
+## Troubleshooting
+
+| Symptom | Likely cause | Fix |
+|---|---|---|
+| HTTP hook always returns `error` | SSRF block on loopback (test). | Call `security.SetAllowLoopbackForTest(true)` in tests. |
+| Prompt hook blocks everything | Evaluator returning free-text (no tool call). | Review `prompt_template`; keep it short + imperative. |
+| Hook stopped firing | Circuit breaker tripped (5 blocks/min). | `UPDATE agent_hooks SET enabled=true WHERE id=...` after fixing upstream cause. |
+| UI `command` radio greyed out | Standard edition. | Use HTTP or prompt, or upgrade to Lite. |
+| Per-turn cap hit | `max_invocations_per_turn` too low. | Raise in hook config; review matcher tightness. |
+| Budget exceeded | Tenant spent monthly token budget. | Raise `tenant_hook_budget.budget_total` or wait for rollover. |
+
+## Migration notes
+
+No data migration required when upgrading from a pre-hooks release. Migration `000052_agent_hooks` creates `agent_hooks`, `hook_executions`, and `tenant_hook_budget`. SQLite users must also have schema version 20 or later.
+
+## Known limitations
+
+- Prompt decision cache is per-process (no cluster-wide Redis yet).
+- No skill-frontmatter hooks (planned post-MVP).
+- No `agent` handler type (inter-agent delegation via prompt instead).
+- Desktop Wails UI has list/detail parity but no dedicated mobile-optimized form.

+
+## ActorID vs UserID in Group Chats
+
+A second identity pattern complements agent identity: **who is acting** vs
+**which scope the action belongs to**. The pattern mirrors agent UUID/key
+but applies to end users in group contexts (Telegram, Discord, Feishu, Zalo).
+
+### The two identities
+
+| Identity | Context key | Helper | Meaning |
+|---|---|---|---|
+| **SCOPE** — namespace / memory | `UserIDKey` | `store.UserIDFromContext(ctx)` | `group:telegram:<chatID>` in Telegram groups; `guild:<guildID>:user:<senderID>` in Discord guilds; sender ID in DMs |
+| **ACTOR** — acting principal | `SenderIDKey` | `store.SenderIDFromContext(ctx)` | Always the individual sender's numeric ID (never group-scoped) |
+| (combined) | — | `store.ActorIDFromContext(ctx)` | `SenderID` if set, else falls back to `UserID` |
+
+### When to use each
+
+| Purpose | Helper | Why |
+|---|---|---|
+| Memory / KG / session key | `UserIDFromContext` / `MemoryUserID` / `KGUserID` | Memory is per-group by design — all members share conversational context |
+| File / path scope | `UserIDFromContext` | Per-group workspace; group members share files |
+| **Permission check** | `SenderIDFromContext` | Checks attribute to the real user, not the group |
+| **Audit trail** (`initiated_by`, event `UserID`) | `ActorIDFromContext` | Traces the real user action across wrappers |
+| **Ownership** (`OwnerID`, creator fields) | `ActorIDFromContext` | A skill published in a group belongs to the individual user |
+| Role / RBAC | `ActorIDFromContext` | Role applies to the human, not the group |
+
+### Group behavior table
+
+| Context | `UserID` | `SenderID` | `ActorID` |
+|---|---|---|---|
+| Telegram DM | sender numeric | sender numeric | sender numeric |
+| Telegram group | `group:telegram:<chatID>` | sender numeric | sender numeric |
+| Discord DM | sender snowflake | sender snowflake | sender snowflake |
+| Discord guild | `guild:<guildID>:user:<senderID>` | sender snowflake | sender snowflake |
+| HTTP API | HTTP user ID | (empty) | HTTP user ID |
+| Cron / subagent system ctx | (inherited / empty) | (empty or propagated) | same as SenderID, else UserID |
+
+### Propagation through wrappers (#915)
+
+When a tool wrapper synthesizes an inbound message (subagent announce,
+delegate announce, teammate dispatch, session_send), the synthetic
+`SenderID` carries routing identity (e.g. `subagent:<taskID>`) — NOT a
+real user. The real acting sender must travel through `InboundMessage.Metadata`
+under `tools.MetaOriginSenderID`, and the next-turn builder copies it to
+`RunRequest.SenderID`. Without this propagation:
+
+- Permission checks against `bus.IsInternalSender(...)` prefixes → **denied**
+  (synthetic senders never match a grant)
+- Empty sender → **denied** (`CheckFileWriterPermission` group-context fail-closed
+  policy)
+
+Code path:
+
+```
+SubagentTask.OriginSenderID
+  → AnnounceMetadata.OriginSenderID
+  → InboundMessage.Metadata[MetaOriginSenderID]
+  → subagentAnnounceRouting.SenderID
+  → RunRequest.SenderID
+  → loop_context.go:WithSenderID(ctx, …)
+  → SenderIDFromContext(ctx) in permission checks
+```
+
+Same chain for delegate (`delegate_tool.announceToParent`) and teammate
+dispatch (`team_tool_dispatch.go`).
+
+### Group permission check policy
+
+`store.CheckFileWriterPermission` / `store.CheckCronPermission` in group
+or guild context (`UserID` starts with `group:` or `guild:`):
+
+- empty `SenderID` → **DENY** (system context must not gain write access silently)
+- synthetic-prefix `SenderID` → **DENY** (`subagent:`, `notification:`, `teammate:`,
+  `system:`, `ticker:`, `session_send_tool`)
+- real numeric `SenderID` → DB lookup; DENY if no `file_writer` allow grant for this sender
+- DB error → fail-open (availability over strictness)
+
+In DM / HTTP / cron-direct context (no group/guild prefix): always allow.
+No per-user writer gate applies.
+
+### Legacy-data tolerance for skill ownership
+
+Skills / cron / delegate audit trails created before #915 migration store
+`UserIDFromContext` values (possibly `group:*` prefixed) in `owner_id` /
+`user_id` columns. Ownership checks at `skill_manage.go` (patch/delete)
+accept either `ActorIDFromContext` (new) or `UserIDFromContext` (legacy).
+This lets existing group-scoped rows remain accessible without a
+destructive backfill. When a user re-publishes a skill, the new row uses
+actor ownership (tighter by default).

+# GitHub Binary Installer
+
+Install CLI tools directly from GitHub Releases at runtime. Covers Go, Rust,
+shell, and other binary-distributed tools not available via `apk` / `pip` / `npm`.
+
+Closes [#741](https://github.com/nextlevelbuilder/goclaw/issues/741).
+
+## Install Syntax
+
+```
+github:owner/repo[@tag]
+```
+
+Examples:
+- `github:cli/cli` → latest release
+- `github:jesseduffield/lazygit@v0.42.0` → specific version
+- `github:sharkdp/fd@v9.0.0` → specific version with dot separator
+
+## How It Works
+
+1. Fetches release metadata from the GitHub API
+2. Auto-selects asset matching `linux` + current arch (amd64 / arm64)
+3. Streams download to a temp file, enforcing a max size cap
+4. Verifies SHA256 if the publisher ships `checksums.txt` / `SHA256SUMS`
+5. Validates ELF magic bytes + 64-bit class + machine matches runtime arch
+6. Extracts archive safely (tar.gz / zip / raw binary) with path-traversal + zip-bomb guards
+7. Installs to `/app/data/.runtime/bin/` (prepended to `$PATH`)
+8. Persists a manifest for later listing + uninstall
+
+## Usage

+token in `config.json`.
+
+| Env var | Default | Notes |
+|---------|---------|-------|
+| `GOCLAW_PACKAGES_GITHUB_TOKEN` | `""` | Optional PAT: rate 60/hr → 5000/hr + private repo access |
+| `GOCLAW_PACKAGES_MAX_ASSET_SIZE_MB` | `200` | Applies to both download cap and 2× uncompressed cap |
+| `GOCLAW_PACKAGES_GITHUB_ALLOWED_ORGS` | `""` | Comma-separated allowlist (empty = all orgs allowed) |
+| `GOCLAW_PACKAGES_GITHUB_BIN_DIR` | `/app/data/.runtime/bin` | Where extracted binaries land |
+| `GOCLAW_PACKAGES_GITHUB_MANIFEST` | `{bin_dir}/../github-packages.json` | Manifest path |
+
+Token scopes:
+- public-only repos: no scopes required
+- private repos: `repo`
+- org-SSO-enforced repos: must be SSO-authorized PAT
+
+## Security
+
+- HTTPS-only downloads with SSRF host allowlist:
+  `github.com`, `api.github.com`, `objects.githubusercontent.com`,
+  `release-assets.githubusercontent.com`, `codeload.github.com`
+- Every redirect hop re-validated (blocks redirect-based host escape)
+- Literal IP hostnames (v4 / v6) always rejected (blocks cloud-metadata access)
+- SHA256 verification when publisher ships `checksums.txt` / `SHA256SUMS` (constant-time compare)
+- ELF magic + 64-bit class + machine-arch validation before `chmod +x`
+- Path-traversal prevention in archive extraction (rejects `..`, absolute, Windows drive, null byte)
+- Zip-bomb guard (cumulative uncompressed bytes capped at 2× max asset size)
+- Symlink / hardlink entries skipped, never written
+- Admin-only API + master-scope guard on install/uninstall
+- Picker endpoint `/v1/packages/github-releases` throttled per user (30 req/min, burst 10) to protect GitHub API quota; anonymous fallback keyed by remote IP. Response is `429 Too Many Requests` with `Retry-After: 60` when tripped.
+- Token never logged (startup log prints `token_set=bool`)
+
+## Troubleshooting
+
+### "glibc not found" / segfault on execution
+
+GoClaw runs on Alpine Linux (musl libc). Many Go/Rust binaries target glibc.
+
+**Fix:** pick a musl-compatible release asset. Look for names containing:
+- `*-musl.tar.gz` (explicit musl)
+- `*-linux-static*` (fully static)
+- Go binaries with `CGO_ENABLED=0` typically work out of the box
+
+Known-good musl releases:
+- `ripgrep`: `ripgrep-*-x86_64-unknown-linux-musl.tar.gz`
+- `starship`: `starship-x86_64-unknown-linux-musl.tar.gz`
+- `gh`: `gh_*_linux_amd64.tar.gz` (static)
+
+### "no matching asset found"
+
+Asset naming doesn't fit the heuristic. Open the release page and confirm assets
+exist for `linux` + your arch. Workaround: file an upstream issue asking for
+standard `linux_amd64` / `linux_arm64` naming.
+
+### "arch mismatch"
+
+Binary is `amd64` but runtime is `arm64` (or vice versa). Pick a release asset
+matching the host arch — the release picker UI filters automatically.
+
+### "rate limit exceeded"
+
+Anonymous GitHub API is capped at 60 req/hr. Set
+`GOCLAW_PACKAGES_GITHUB_TOKEN` to bump to 5000/hr.
+
+### "checksum mismatch"
+
+Hard-fail. Indicates tampered download or publisher re-signing without updating
+the release. Do not force-install; report upstream.
+
+## Limitations (Phase 1)
+
+- Linux-only (Lite/Desktop editions not yet supported)
+- Docker edition only (runtime dir `/app/data/.runtime/bin`)
+- Installs all top-level executables in an archive (no interactive picker if
+  archive contains multiple binaries)
+- No version history / rollback — re-installing replaces in place
+- Global manifest (not per-tenant)
+

+# Example Hooks Library
+
+Copy-paste-ready hook configurations for common use cases. Each JSON is a valid `hooks.create` WS payload — send it via the Web UI → **Hooks → Create** (paste into the relevant fields) or POST directly to the RPC endpoint.
+
+## Safety reminders
+
+- **Review regex matchers** before enabling. A too-broad matcher on a prompt hook drains token budget. Prefer anchored patterns like `^(exec|shell)$`.
+- **`command` hooks require Lite edition.** On Standard the UI greys them out and dispatch fails closed.
+- **SSRF-safe HTTP hooks**: URLs are resolved + pinned before the request. Loopback/private ranges are blocked in production.
+- **Authorization headers** get AES-256-GCM encrypted at rest. Never commit plaintext secrets to these JSON files.
+- **Test in staging first.** Use the `Test` tab in the UI — it runs with `dryRun=true` and does NOT write to `hook_executions`.
+
+## Catalog
+
+| File | Event | Handler | Scope | Purpose |
+|---|---|---|---|---|
+| `block-rm-rf.json` | `pre_tool_use` | command | agent | Block dangerous `rm -rf /` via local shell script. Lite only. |
+| `auto-lint-after-write.json` | `post_tool_use` | http | agent | Fire-and-forget lint request after file writes. |
+| `audit-tool-usage.json` | `post_tool_use` | http | tenant | Stream every tool invocation to an external audit sink. |
+| `session-context-injector.json` | `session_start` | http | agent | Injects project metadata into the agent context at start. |
+| `notify-discord-on-stop.json` | `stop` | http | tenant | Discord webhook notification when a session ends. |
+
+## Usage
+
+### Via Web UI
+
+1. Open `/hooks` → click **Create hook**.
+2. Copy fields from the example JSON into the form.
+3. For `http.config.headers`, paste your secret in the Authorization field — the server encrypts it before storing.
+4. Click **Save**, then **Test** with a sample event before enabling in production.
+
+### Via WS RPC
+
+```bash
+wscat -c ws://localhost:18790/ws
+# After connect:
+> {"id":"1","method":"hooks.create","params": <paste JSON here> }
+```
+
+## Conventions
+
+- `tenant_id` omitted → current tenant from WS session. Set `scope: "global"` to apply cross-tenant (master required).
+- `agent_id` required for `scope: "agent"`; otherwise leave null.
+- `priority: 10` is the recommended default. Higher priority hooks run first; first `block` wins the chain.
+- `on_timeout: "block"` for anything security-sensitive; `"allow"` for observation-only.
