Release: Vault enhancements, tenant tool config, coverage waves, agent identity hardening (#851)

* fix(ci): skip CI condition in semantic-release for main branch

go-semantic-release auto-detects the default branch from GitHub API
(which is dev), but releases are cut from main. The CI condition
rejects runs on non-default branches. Use --no-ci to bypass this
check since the workflow already gates on push to main.

* docs: document CI/CD pipelines, release flow, and v2.66.0 changelog

- CLAUDE.md: add CI/CD & Releases section with workflow table, tag
  patterns, Docker variants, beta/desktop release commands
- CONTRIBUTING.md: expand Releases section with standard (auto),
  beta (manual tag), and desktop release workflows
- docs/17-changelog.md: add v2.66.0 entry covering IDOR fix, BytePlus
  provider, per-agent grants, beta pipeline, and CI fixes

* fix(telegram): handle group-to-supergroup migration seamlessly

When a Telegram group upgrades to a supergroup, the chat ID changes and
all existing references become stale. This caused send failures (400),
orphaned sessions, and required manual re-pairing.

Add dual-path migration handling:
- Proactive: intercept inbound MigrateToChatID before isServiceMessage
- Reactive: detect 400 + MigrateToChatID on send, migrate DB, retry

DB migration updates in a single transaction (scoped by tenant + channel):
- paired_devices: sender_id, chat_id
- sessions: session_key, user_id
- channel_contacts: sender_id
- channel_pending_messages: history_key

Also invalidates in-memory caches (approvedGroups, pairingReplySent,
groupHistory) and handles media sends via migration retry in Send().

* fix(tools): quote-aware shell operator detection in credentialed exec (#700) (#702)

* fix(tools): quote-aware shell operator detection in credentialed exec (#700)

- Replace detectShellOperators with detectUnquotedShellOperators in
  credentialed exec path — respects single/double quoting so that
  characters like | inside argument values (e.g. --jq '.[0] | .name')
  are not falsely flagged as shell operators
- Pass raw command string (preserving quotes) to executeCredentialed
  instead of reconstructing from parsed args
- Downgrade "no credential found" log from Warn to Debug (fires for
  every non-credentialed command, too noisy at Warn)
- Add extractUnquotedSegments() helper with comprehensive tests

* fix(tools): handle backslash escape outside quotes in shell operator detection

extractUnquotedSegments did not handle \ as an escape character outside
of quotes, causing \" to incorrectly enter double-quote mode. This hid
subsequent shell operators from detection (e.g. gh \"arg\" | env would
not detect the unquoted pipe).

Add backslash escape handling in the unquoted state to match
go-shellwords parsing behavior. Both \ and the escaped character are
emitted as unquoted content so operator detection still catches them.

* feat(infra): tracing recovery, browser cleanup, CLI fixes, UI workspace split (#709)

- Tracing: recover stale running traces/spans on startup (PG + SQLite)
- Browser: Chrome orphan cleanup via launcher PID, timeouts, Leakless
- Claude CLI: WaitDelay 5s + context-cancel early exit
- Agent loop: safety-net defer to finalize orphan root traces
- UI: split workspace sharing into separate Memory and KG toggles
- Minor: for-range idiom, min() builtin

* fix(prompt): skip credentialed CLI context when exec tool is denied

Agents with exec in their deny list cannot run CLI commands, so
injecting wrangler/gh credential context is misleading — the LLM
sees instructions for tools it cannot use. Gate the section on
exec being present in the filtered tool list.

* fix(ui): improve traces table layout and readability

Compact columns: status as icon-only, merge time+duration into one column.
Truncate long user IDs, clean <media:*> tags from preview, move badges to second line.

* fix(security): harden exec path exemption matching

- Add absolute path exemption for dataDir/skills-store/ (fixes skill
  scripts using absolute paths like /app/data/skills-store/ being denied)
- Strip surrounding quotes before prefix matching (LLMs often quote paths)
- Reject path traversal ("..") in exempt fields to prevent escape
- Switch from "any field exempt → skip" to per-field matching: only exempt
  if ALL fields that match the deny pattern are individually exempt
- Closes pipe/comment bypass vectors where an exempt path in one argument
  would exempt the entire command including non-exempt paths

Includes 27 test cases covering: legitimate access, quoted paths,
path traversal, unicode bypass, pipe/comment bypass, mixed args.

* feat(whatsapp): add native WhatsApp channel with whatsmeow (#720)

Replace Node.js Baileys bridge with native go.mau.fi/whatsmeow — zero
external dependencies. QR auth, media support, markdown formatting,
typing indicators, dual JID/LID identity, group policies, pairing.

Resolves #703

* fix(chat): load message history on first conversation click (#730)

* fix(chat): load message history when selecting existing conversation from clean state

The skipNextHistoryRef was unconditionally set when sessionKey transitioned
from empty to non-empty. This prevented loadHistory() from running when
clicking an existing conversation from the initial /chat page. The skip
was only intended for the new-chat send flow where the optimistic message
is already displayed.

Guard the skip with expectingRunRef so it only activates when a message
send is in flight.

Closes #729

* docs: add UI diff evidence for PR #730

Before/after screenshots and HTML comparison report showing
first conversation click behavior fix.

* fix(permissions): use cron-specific permission check for cron tool (#725)

* fix(security): harden exec path exemption matching (#721)

- Add absolute path exemption for dataDir/skills-store/ (fixes skill
  scripts using absolute paths like /app/data/skills-store/ being denied)
- Strip surrounding quotes before prefix matching (LLMs often quote paths)
- Reject path traversal ("..") in exempt fields to prevent escape
- Switch from "any field exempt → skip" to per-field matching: only exempt
  if ALL fields that match the deny pattern are individually exempt
- Closes pipe/comment bypass vectors where an exempt path in one argument
  would exempt the entire command including non-exempt paths

Includes 27 test cases covering: legitimate access, quoted paths,
path traversal, unicode bypass, pipe/comment bypass, mixed args.

* fix(permissions): use cron-specific permission check for cron tool

Cron tool was hardcoded to check `file_writer` configType via
CheckFileWriterPermission(), ignoring the `cron` configType that
the UI actually saves when granting cron permissions. This caused
agents in group chats to be denied cron access even with correct
permission configured.

Add ConfigTypeCron constant and CheckCronPermission() that checks
`cron` configType first, falling back to `file_writer`.

* fix(exec): allow uploaded files in active workspaces (#748)

Shell-aware command parsing, dynamic workspace exemptions, and symlink canonicalization for exec path denial. Fixes #739.

* refactor(exec): extract path exemption logic to separate file

Move shell-aware parsing, dynamic workspace exemptions, path alias
variants, and canonicalization functions from shell.go (688 LOC) to
shell_path_exemption.go (284 LOC) for maintainability.

* feat(agent): centralized tenant user identity resolution for credentials

Add CredentialUserID context key that resolves channel contacts to merged
tenant users for credential lookups (SecureCLI, MCP). Keeps UserID
unchanged for session/workspace scoping. Resolves group senders, group
contacts, and unresolved DMs via ContactStore with 60s TTL cache.

* fix(ui): improve traces table column layout

Add width constraints and whitespace-nowrap to prevent column wrapping
on narrow viewports. Cherry-picked from dev-v3.

* fix(ui): enable search filtering on knowledge graph view (#758)

Search box on /knowledge-graph only filtered table view. Add useMemo client-side filtering of graph entities by name/type/description, only show relations where both endpoints match.

Closes #759

* feat: add zoom controls to knowledge graph (#757)

Add +/- buttons and percentage display to the knowledge graph stats bar
so users can zoom without relying solely on mouse wheel. Uses existing
react-force-graph-2D zoom() API with 1.5x step and 300ms animation.

Closes #755

* fix(providers): use DB name for ClaudeCLI, ACP, and Anthropic registration

Provider Name() methods returned hardcoded strings, so DB-registered
providers with custom names got wrong registry key — causing "provider
not found" fallback. Add WithClaudeCLIName/WithACPName/WithAnthropicName
options, pass p.Name from DB registration paths. Config-based paths
keep hardcoded defaults.

Closes #742

* fix(agent): correct soft-trim head/tail budget allocation when tail is important (#723)

Co-authored-by: quxy5 <quxy5@outlook.com>

* feat(v3): core architecture redesign — pipeline, memory, vault, evolution, providers, orchestration (#790)

* feat(v3): add core interface contracts and migration for v3 redesign

Foundation interfaces: TokenCounter, WorkspaceContext, DomainEventBus,
ProviderAdapter/Capabilities. Pipeline: Stage, RunState, MessageBuffer,
substates, Pipeline orchestrator. Memory: EpisodicStore, AutoInjector,
KG temporal extensions, consolidation workers. System integration:
PromptConfig, ToolCapability, Retriever. Orchestration: OrchestrationMode,
EvolutionMetrics/SuggestionStore. Migration 000037: episodic_summaries,
evolution tables, KG temporal columns. Schema version 36→37.

* refactor(plans): mark all v3 design phases complete with file references

* fix(v3): address code review findings on design contracts

- C1: add missing l0_abstract column to episodic_summaries migration
- C2: align EpisodicSummary ID/TenantID/AgentID to uuid.UUID
- H1: document tenant_id scoping requirement on EpisodicStore
- H2: add UNIQUE constraint on (agent_id, user_id, source_id) for dedup
- H4: clarify ProviderAdapter vs Provider relationship in doc
- M3: set state.ExitCode on BreakLoop/AbortRun in pipeline
- M6: store full PipelineConfig in Pipeline struct
- Edge: add WHERE embedding IS NOT NULL on HNSW index

* fix(v3): second-pass review fixes

- H1: use context.WithoutCancel for finalize + set ExitCode on ctx cancel
- H2: use utf8.RuneCountInString consistently in FallbackCounter
- H3: longest-prefix-match in ModelContextWindow (prevents wrong tokenizer)
- H4: return unsubscribe cleanup func from consolidation.Register

* feat(v3): implement DomainEventBus with worker pool, dedup, and retry

Worker pool processes events from buffered channel. SourceID-based dedup
prevents duplicate processing. Exponential backoff retry on handler error.
Panic recovery per handler. Graceful shutdown via Drain(). 8/8 tests pass
with race detector.

* feat(v3): implement ProviderAdapter for Anthropic, OpenAI, DashScope, Codex

Add CapabilitiesAware to all 6 providers. Create ProviderAdapter
implementations that delegate to existing buildRequestBody/parseResponse
for DRY. ClaudeCLI and ACP get capabilities only (subprocess transport).
DashScope wraps OpenAI adapter with StreamWithTools=false override.

* feat(v3): implement WorkspaceContext Resolver for 6 scenarios

Stateless resolver produces immutable WorkspaceContext at run start.
Handles personal/group/predefined/team-shared/team-isolated/delegation.
Wired into loop_context.go behind v3PipelineEnabled flag (additive,
v2 path unchanged). Includes delegation path boundary check,
master tenant bypass, and tenant slug path composition.

* feat(v3): implement tiktoken TokenCounter with BPE encoding + cache

Adds tiktoken-go for accurate cl100k_base/o200k_base token counting.
Per-message FNV-1a hash cache avoids re-encoding unchanged history.
Falls back to rune/3 heuristic for unknown models. NewTokenCounter
factory selects implementation at build time.

* feat(v3): promote 12 other_config JSONB fields to dedicated agent columns

Extract emoji, agent_description, thinking_level, max_tokens,
self_evolve, skill_evolve, skill_nudge_interval, reasoning_config,
workspace_sharing, chatgpt_oauth_routing, shell_deny_groups, and
kg_dedup_config from the catch-all other_config JSONB into proper
columns with DB-level types and defaults.

- Migration: PG (000037) + SQLite (schema v6→7) with backfill
- Go: AgentData struct + simplified Parse* methods
- Store: SELECT/INSERT/scan updated for both PG and SQLite
- Gateway: create/update handlers accept promoted fields
- HTTP: export/import with legacy backward compat
- Web UI: all 15 frontend files read/write from top level

* feat(v3): implement Knowledge Vault with unified search, wikilinks, and FS sync

Migration 000038 adds vault_documents (FTS+pgvector), vault_links, vault_versions
tables. VaultStore interface with PG implementation for document CRUD, hybrid
FTS+vector search, and bidirectional link management. All queries enforce
tenant_id isolation including JOIN-based scoping on link operations.

FS sync layer: SHA-256 content hashing, VaultInterceptor hooks into write_file/
read_file for auto-registration and lazy sync, fsnotify watcher with 500ms
debounce. Wikilink engine parses [[target]] syntax, resolves targets via
3-step strategy, and maintains vault_links on write.

VaultSearchService fans out queries across vault, episodic, and KG stores in
parallel with per-source score normalization and weighted merge. AutoInjector
and Retriever implementations for pipeline integration.

Three agent tools: vault_search (unified discovery), vault_link (explicit
linking), vault_backlinks (dependency tracing). Feature-flagged via
v3_vault_enabled agent setting.

* feat(v3): wire vault into gateway startup + add unit tests

Wire VaultStore embedding provider, VaultSearchService, VaultInterceptor
on read/write tools, and register vault_search/vault_link/vault_backlinks
tools in gateway_vault_wiring.go. All wiring gated by stores.Vault != nil.

Add 28 unit tests for ContentHash, ContentHashFile, and ExtractWikilinks
covering edge cases, unicode, display text, context windows, and offsets.

* feat(v3): implement stage-based pipeline loop with 8 pluggable stages

Decompose monolithic agent loop into internal/pipeline/ package:
- 6 stages: Context, Think, Prune+MemoryFlush, Tool, Observe+Checkpoint, Finalize
- Foundation types: Stage interface, RunState with 7 typed substates, MessageBuffer
- Pipeline orchestrator with setup/iteration/finalize 3-phase execution
- Callback-based PipelineDeps avoids circular import with agent package
- Feature-flagged via v3PipelineEnabled in Loop.Run()
- All 7 exit conditions preserved (no tools, max iter, truncation, loop kill,
  read-only streak, tool budget, ctx cancel)

* feat(v3): wire pipeline callbacks to Loop methods + add 71 unit tests

Wire 15 of 17 PipelineDeps callbacks from Loop methods via closures:
- Context: LoadContextFiles, BuildMessages, EnrichMedia, InjectReminders
- Think: BuildFilteredTools, CallLLM (stream/sync)
- Prune: PruneMessages, CompactMessages
- Memory: RunMemoryFlush
- Finalize: SanitizeContent, FlushMessages, UpdateMetadata, BootstrapCleanup, MaybeSummarize
- Remaining: ExecuteToolCall, CheckReadOnly (deep loop.go integration)

Add comprehensive test suite (71 tests, all passing with -race):
- MessageBuffer: 10 tests (append, flush, replace, counts)
- Pipeline.Run: 14 tests (3-phase flow, exit conditions, ctx cancel)
- Stage tests: 47 tests (ThinkStage nudges/truncation, PruneStage budget,
  ToolStage parallel/exit, ObserveStage content, CheckpointStage interval,
  FinalizeStage cleanup)

* feat(v3): wire remaining 2 callbacks (ExecuteToolCall, CheckReadOnly)

Complete callback wiring — 17/17 PipelineDeps callbacks now active:
- ExecuteToolCall: resolves tool name, executes via registry, processes
  result via existing processToolResult with loop detection bridge
- CheckReadOnly: delegates to checkReadOnlyStreak via bridge runState
- Bridge runState shares loop detection state between pipeline and agent

* fix(v3): eliminate data race in tool execution + capture injected messages

- Remove parallel tool execution path — serialize all tool calls to avoid
  data races on shared bridgeRS (loop detector, media results, deliverables)
- Loop kill checked after each tool (mid-batch early exit)
- BuildFilteredTools: capture and append injected tool-awareness messages
- Rename test to reflect sequential execution

* feat(v3): wire ResolveWorkspace, safe parallel tools, ContextStage tests

- Wire ResolveWorkspace callback via workspace.NewResolver() with
  ResolveParams from Loop fields (no longer a nil stub)
- Re-add safe parallel tool execution: split into ExecuteToolRaw
  (parallel I/O) + ProcessToolResult (sequential state mutation)
  with opaque rawData pass-through (no double execution)
- Add 12 unit tests for ContextStage (8) + MemoryFlushStage (3)
- Split tool callbacks to loop_pipeline_tool_callbacks.go (under 200 lines)
- Capture buildFilteredTools injected messages

* feat(v3): add episodic memory store + temporal KG columns

Phase 1 — Episodic Store:
- Migration 000039: episodic_summaries table with pgvector, FTS, L0 abstracts
- EpisodicStore PG impl: CRUD, hybrid FTS+vector search, ExistsBySourceID,
  PruneExpired. Idempotent via source_id UNIQUE constraint.

Phase 2 — Temporal KG:
- Migration 000040: valid_from/valid_until on kg_entities + kg_relations,
  partial indexes for current-facts queries, epoch→timestamptz backfill
- ListEntitiesTemporal: current-only, point-in-time, or include-expired modes
- SupersedeEntity: atomic expire-old + insert-new in single transaction

Schema version bumped to 40.

* fix(v3): review fixes for episodic store + temporal KG

- C1: Fix column name mismatch turn_count vs message_count in Go SQL
- C2: Remove redundant migration 000040 (000037 already adds temporal KG columns)
- H1: Use time.Time not int64 for TIMESTAMPTZ columns in SupersedeEntity
- H2: Add tenant_id scoping to Get/Delete for tenant isolation
- M2: Fix scanEntityTemporal to convert TIMESTAMPTZ→UnixMilli correctly
- L1: Remove unused uuid import from episodic_search.go
- Schema version corrected to 39 (only 000039 is new)

* feat(v3): implement consolidation pipeline with 3 event-driven workers

Event chain: session.completed → EpisodicWorker → episodic.created →
SemanticWorker → entity.upserted → DedupWorker

- EpisodicWorker: reuses compaction summary or calls LLM, generates L0
  abstract (extractive), idempotent via source_id check
- SemanticWorker: extracts KG facts from episodic summary via existing
  Extractor, sets temporal valid_from, publishes entity.upserted
- DedupWorker: runs DedupAfterExtraction on new entity IDs (terminal)
- L0 abstract: sentence-based extraction (~50 tokens), no LLM needed
- All workers registered via DomainEventBus.Subscribe()

* feat(v3): implement progressive loading with L0 auto-inject + unified search

- AutoInjector: searches episodic store, builds L0 prompt section (~200 tokens),
  skips trivial messages via stopword filter
- L1Cache: in-memory LRU (500 entries, 1h TTL) for structured overviews
- UnifiedSearch: cross-tier search merging episodic + document results by score
- ContextStage integration: AutoInject callback appends memory section to system prompt
- MemorySection field added to ContextState for observability

* feat(v3): add memory_expand tool for L2 episodic retrieval

New tool: memory_expand(id) returns full episodic summary with metadata.
Complements memory_search L0/L1 results with deep L2 access.
Nil-safe: returns error message when episodic store not available.

Gateway wiring + memory_search depth param + kg_search temporal param
deferred to runtime integration phase.

* feat(v3): complete Phase 5 — tool extensions + gateway wiring

- memory_search: add depth param + episodic tier search merged with docs
- kg_search: add as_of temporal param, use ListEntitiesTemporal
- memory_expand: registered in gateway startup
- Gateway: Episodic field in Stores, PGEpisodicStore in factory,
  embedding provider wired, tools connected to episodic store

* fix(v3): Phase 3 review fixes — tenant isolation + AutoInject args

- C1: Add tenant_id filter to ftsSearch, vectorSearch, List queries
  (prevents cross-tenant episodic memory leaks)
- C2: Fix AutoInject callback signature — agent/tenant captured by
  closure, only userMessage + userID passed explicitly
- H1: Add tenant_id to List query

* feat(v3): wire per-agent v3 flags from DB into dual-mode gate

Parse v3_pipeline_enabled, v3_memory_enabled, v3_retrieval_enabled from
agent other_config JSONB via ParseV3Flags(). Resolver now sets all flags
on LoopConfig so the existing gate in loop_run.go reads from DB.

- V3Flags struct + ParseV3Flags() + ValidateV3Flags() in store layer
- v3MemoryEnabled/v3RetrievalEnabled added to Loop, LoopConfig, PipelineConfig
- Auto-inject gated on V3RetrievalEnabled (was unconditional)
- Structured perf logging for v3 pipeline runs
- v3 flag validation on both WS agent.update and HTTP PUT endpoints

* feat(v3): wire AutoInjector into pipeline for L0 memory auto-inject

Create AutoInjector at gateway startup from episodic store, pass through
ResolverDeps → LoopConfig → Loop. Pipeline adapter builds AutoInject
callback capturing agent/tenant context via closure.

ContextStage already gates on V3RetrievalEnabled + AutoInject != nil.

* feat(v3): add tool metadata map + capability-based deny rules

Registry gains per-tool ToolMetadata map with RegisterWithMetadata()
and GetMetadata() (infers defaults from tool name when not explicit).
PolicyEngine gains DenyCapability() for RBAC integration — tools with
denied capabilities filtered at step 8 after existing 7-step pipeline.

* fix(v3): add RWMutex to PolicyEngine capability deny fields

DenyCapability() and SetRegistry() now guarded by sync.RWMutex.
FilterTools reads snapshot under RLock. Prevents data race when
capability rules are modified concurrently with tool filtering.

* feat(v3): implement delegate tool for inter-agent task delegation

New `delegate` tool wraps existing agent_links infrastructure
(CanDelegate, DelegateTargets). Supports async (fire-and-forget)
and sync (block with timeout) modes. Permission checked via
AgentLinkStore. Events emitted: delegate.sent/completed/failed.

DelegateRunFunc injected by gateway to avoid circular dependency.

* feat(v3): complete 3 deferred implementations

1. OrchestrationMode resolution: ResolveOrchestrationMode() checks
   team membership → delegate links → spawn (priority order).

2. PG EvolutionMetricsStore: RecordMetric, QueryMetrics, aggregate
   tool/retrieval metrics, TTL cleanup. All queries tenant-scoped.

3. BridgePromptBuilder: implements PromptBuilder interface by
   delegating to existing BuildSystemPrompt(). Appends v3 memory
   L0 section when enabled. Ready for template engine swap later.

* fix(v3): address code review findings on commits 5-6

- C1: CanDelegate now tenant-scoped (fail-closed on missing tenant)
- H1: Sync delegate timeout capped at 600s
- H2: Async goroutine gets 10min deadline (prevents leaks)
- H3: JSONB casts use COALESCE/NULLIF guards (handles missing fields)
- M1/M2: Remove dead code (formatVaultSection, memoryL0ToStrings)

* fix(teams): stop auto-creating agent_links for team members

Teams use agent_team_members table directly — agent_links caused
context confusion between team dispatch and delegation systems.

- Remove autoCreateTeamLinks() calls from team create + member add
- Remove link cleanup from member remove
- Remove dead autoCreateTeamLinks() function
- Append DELETE to migration 000039: clear team-created agent_links

* fix(v3): tenant isolation for all agent_links queries + PromptBuilder Instructions

- DelegateTargets, GetLinkBetween, SearchDelegateTargets,
  SearchDelegateTargetsByEmbedding, DeleteTeamLinksForAgent all now
  scoped by tenant_id (fail-closed on missing tenant)
- BridgePromptBuilder now maps Instructions/InstructionContent to
  AGENTS.md context file (was silently dropped)

* feat(v3): wire orchestration mode + evolution metrics into agent loop

- Orchestration mode: resolver resolves mode from team/links, tool filter
  hides delegate/team_tasks based on mode, prompt builder injects delegation
  targets section
- Evolution metrics: non-blocking goroutine records tool execution metrics
  (name, success, duration) via EvolutionMetricsStore in both v2 loop and
  v3 pipeline paths (sequential + parallel)
- Fix review findings: tenant ID propagated via store.WithTenantID in
  background goroutine, 5s timeout prevents goroutine leak

* feat(v3): implement suggestion engine with pluggable analysis rules

- PG EvolutionSuggestionStore: CRUD for agent_evolution_suggestions table
- SuggestionEngine: aggregates 7-day metrics, runs rules, deduplicates
  pending suggestions per type before creating new ones
- 3 initial rules: LowRetrievalUsage (usage_rate<0.2), ToolFailure
  (success_rate<0.1), RepeatedTool (>100 calls/week → suggest skill)
- EventSuggestionCreated event type added to eventbus
- Cron wiring deferred to gateway startup integration pass

* feat(v3): implement auto-adapt guardrails with apply/rollback

- AdaptationGuardrails: max delta per cycle, min data points, locked
  params, rollback-on-drop percentage
- ApplySuggestion: applies threshold suggestions to agent other_config
  JSONB, stores baseline for rollback
- RollbackSuggestion: restores baseline values from suggestion params
- EvaluateApplied: compares post-apply metrics to baseline, auto-rolls
  back when quality drops beyond threshold
- Scope limited to retrieval params only (never security settings)

* feat(v3): wire evolution stores + daily/weekly cron for suggestions

- Add EvolutionMetrics + EvolutionSuggestions to Stores struct + PG factory
- Wire EvolutionMetricsStore into ResolverDeps (cmd/gateway_managed.go)
- Add gateway_evolution_cron.go: daily suggestion analysis + weekly
  evaluation/rollback for applied suggestions
- Cron runs as background goroutine with 5-min timeout per cycle

* fix(v3): address code review findings on evolution engine

- C1: persist baseline parameters before marking suggestion as applied
  (was building map but never saving — rollback would always fail)
- H1: add tenant_id isolation to UpdateSuggestionStatus, GetSuggestion,
  and new UpdateSuggestionParameters method

* test(v3): add unit tests for orchestration, suggestions, guardrails, prompt

- orchestration_mode_test: orchModeDenyTools (4 modes) + ResolveOrchestrationMode
  (4 scenarios with mock stores)
- suggestion_rules_test: LowRetrievalUsage, ToolFailure, RepeatedTool with
  threshold boundary tests (at/below/above min data points)
- evolution_guardrails_test: DefaultGuardrails values + CheckGuardrails
  (insufficient data, locked params, zero-min fallback)
- prompt_builder_orchestration_test: BridgePromptBuilder orchestration section
  presence/absence across 4 scenarios + target content verification

* test(v3): add integration tests for evolution metrics + suggestions

- Test helper: shared PG connection with sync.Once migration, per-test
  tenant+agent seed with cleanup
- Evolution metrics: RecordMetric, AggregateToolMetrics (success rate),
  Cleanup (TTL deletion)
- Evolution suggestions: full CRUD, UpdateSuggestionParameters (baseline
  persist), tenant isolation (cross-tenant read blocked)
- Pipeline E2E: seed 25 failed tools + 55 low-usage retrievals, verify
  SuggestionEngine creates suggestions, verify dedup on second run
- Fix: migration 039 de-duped (episodic_summaries already in 037)
- Fix: NULL reviewed_by scan via sql.NullString

* feat(v3): add HTTP API handlers for evolution, vault, episodic, orchestration, v3-flags

5 new handler files exposing v3 backend stores as REST endpoints:
- evolution_handlers.go: metrics query/aggregate + suggestions CRUD
- vault_handlers.go: cross-agent document listing + search + links
- episodic_handlers.go: episodic summaries list + hybrid search
- orchestration_handlers.go: computed mode + delegate targets (read-only)
- v3_flags_handlers.go: per-agent v3 feature flag get/toggle

Store fixes from code review:
- episodic FTS: use inline to_tsvector (no stored tsv column)
- episodic: conditional user_id filter in List + Search (admin view)
- episodic: add tenant_id to ExistsBySourceID + PruneExpired
- evolution: require tenant_id in context (no struct fallback)
- evolution: check RowsAffected on suggestion updates
- vault: optional agent_id filter in ListDocuments (cross-agent)

* feat(v3): add web UI for evolution tab, v3 settings, vault page, episodic memory

Agent Detail enhancements:
- V3 Settings section: pipeline/memory/retrieval flag toggles
- Orchestration section: mode badge + delegate targets display
- Evolution section: added metrics + suggestions v3 flag toggles
- Evolution tab: Recharts metrics charts + suggestion review table
  with approve/reject/rollback actions + guardrails card

New pages:
- /vault: Knowledge Vault document registry with cross-agent listing,
  hybrid search dialog, document detail with wikilinks
- Memory page: added Episodic Memory tab with summary cards,
  expandable details, key topic badges, and hybrid search

Infrastructure:
- HttpClient: added patch() method
- Query keys: v3Flags, orchestration, evolution namespaces
- 4 new hooks: use-v3-flags, use-orchestration, use-evolution-metrics,
  use-evolution-suggestions, use-vault, use-episodic
- i18n: vault namespace (en/vi/zh), agents + memory keys updated
- Reused formatRelativeTime from lib/format.ts (eliminated 3 duplicates)

* refactor(http): add bindJSON helper and migrate all decode call sites

Replace 36 json.NewDecoder(r.Body).Decode + error blocks with bindJSON
across 20 HTTP handler files. Standardizes decode error responses to
structured writeError format. Fixes unchecked decode in handleIndexAll.

* refactor(store): adopt sqlx for PG scan operations (Phase 1+2)

Add jmoiron/sqlx v1.4.0 with camelToSnake json tag mapper.
Migrate scan-heavy PG store methods to sqlx Get/Select:
- tracing.go: GetTrace, ListTraces, ListChildTraces, GetTraceSpans, GetCostSummary
- heartbeat.go: Get, ListDue, ListLogs
- providers.go: GetProvider, GetProviderByName, ListProviders, ListAllProviders
- mcp_servers.go: GetServer, GetServerByName, ListServers
- pairing.go: ListPending, ListPaired
- agents_export_queries.go: 5 export functions
- agents_export_team_queries.go: exportTeamMembers, ExportAgentLinks

All writes (INSERT/UPDATE/DELETE), execMapUpdate, and dynamic WHERE
builders remain raw SQL. Zero behavior change.

* refactor(store): adopt sqlx for SQLite scan operations (Phase 3)

Migrate SQLite store scan methods to sqlx Get/Select:
- providers.go: GetProvider, GetProviderByName, ListProviders, ListAllProviders
- tenants.go: GetTenant, GetTenantBySlug, ListTenants, GetTenantUser, ListUsers, ListUserTenants
- mcp_servers.go: GetServer, GetServerByName, ListServers

Create sqlx_scan_structs.go with sqliteTime-aware scan structs
(providerRow, tenantRow, tenantUserRow, mcpServerRow) to handle
SQLite TEXT timestamp parsing via StructScan.

* refactor(store): migrate PG bulk scan operations to sqlx (Phase 4)

Migrate scan-heavy methods across 6 PG store files:
- tenant_store.go: GetTenant, GetTenantBySlug, ListTenants, GetTenantUser,
  ListUsers, ListUserTenants — removed 3 scan helpers
- teams.go: ListTeams, GetTeam, ListMembers, ListMembersByTenant
- teams_tasks_activity.go: ListComments, ListEvents, ListFollowUps
- pending_message_store.go: ListPending, ListByHistoryKey
- skills_grants.go: ListAgentGrants
- config_permissions.go: CheckPermission

~20 scan ops converted. Files with encryption post-processing,
pq.Array, pgvector, or dynamic SQL kept raw.

* refactor(store): extract shared CamelToSnake mapper, add UUIDArray usage note

- Move camelToSnake to internal/store/column_mapper.go (DRY)
- Both pg and sqlitestore packages now import shared CamelToSnake
- Add planned-use comment on UUIDArray type

* refactor(cli): migrate commands from config.json to HTTP API, add providers/setup/TUI

- Add unified HTTP client (gateway_http_client.go) with auth, error parsing, typed generics
- Rewrite agent list/add/delete to use gateway HTTP API instead of config.json
- Rewrite channels list to HTTP API, add channels add/delete subcommands
- Replace models command with full providers CRUD (list/add/update/delete/verify)
- Add setup wizard command (provider → agent → channel post-onboard flow)
- Add Bubble Tea TUI behind build tag (tui/!tui with noop fallback)
- Update onboard next-steps to mention goclaw setup
- Add build-tui Makefile target
- Fix URL path injection (url.PathEscape on all user-supplied path segments)
- Fix UTF-8 truncation in skills description display

* refactor(store): add explicit db struct tags, fix sqlx mapper for heartbeat scan error

Switch sqlx mapper from NewMapperFunc (which only applies CamelToSnake to
field names, not tag values) to NewMapperFunc("db", CamelToSnake) with
explicit db:"column_name" tags on all store structs.

Root cause: NewMapperFunc("json", fn) sets mapFunc but not tagMapFunc,
so camelCase json tags like "agentId" were used as-is instead of being
converted to "agent_id", causing "missing destination name" scan errors.

Fix: use db struct tags as the source of truth for column mapping.
Every DB entity field gets db:"column_name", nested JSON configs and
runtime-only structs get db:"-".

* test(store): add integration tests for 13 store interfaces (70 tests)

Cover Tier 1 (critical) + Tier 2 (security) stores with integration tests
running against pgvector pg18. Coverage from 2.4% to ~54%.

Stores tested: Session, Agent, Team/Task, Memory, KnowledgeGraph, Vault,
MCP Server, API Key, ConfigPermission, Contact.

Infrastructure: fixture builders (seedTeam, seedMCPServer, etc.),
mock EmbeddingProvider, multi-tenant helpers, expanded cleanup.

* fix(store): resolve NULL scan bugs in MCP server and task metadata

- mcp_servers: COALESCE nullable TEXT columns (display_name, command,
  url, api_key, tool_prefix) to prevent sqlx scan failures
- mcp_servers_access: COALESCE nullable JSONB columns in ListAgentGrants
  (tool_allow, tool_deny, config_overrides) to prevent silent row drops
- teams_tasks: default task metadata to '{}' instead of nil to satisfy
  NOT NULL constraint on CreateTask
- sqlx_helpers: export InitSqlx for integration test setup

* feat(pipeline): fix v3 pipeline context injection, tracing, KG temporal filters

- Pipeline context: add InjectContext + LoadSessionHistory callbacks to
  ContextStage, propagate enriched ctx via state.Ctx for iteration stages
- Pipeline tracing: wrap makeCallLLM with emitLLMSpanStart/End, wrap
  makeExecuteToolCall/Raw with emitToolSpanStart/End
- Token counter: switch pipeline from FallbackCounter to TiktokenCounter
- KG temporal: add valid_until IS NULL filter to all entity/relation
  queries (list, search, vector, FTS, traversal CTE, stats)
- Skills: add SkillEmbedder interface for future hybrid BM25+vector search
- Cache: remove unused tenantResolve dead code from PermissionCache
- Store: fix NULL scan bugs in tracing metadata and agent skill_nudge
- Test: add TestStoreKG_TemporalFilter integration test
- UI: add v3 version badge, evolution section, memory/traces improvements

* refactor(store): migrate KG store from raw sql.Rows to sqlx StructScan

Migrate 6 knowledge graph store files from manual rows.Scan() to
pkgSqlxDB.GetContext/SelectContext with intermediate scan row structs.

- Add entityRow, relationRow, traversalRow, dedupCandidateRow structs
  with json.RawMessage for jsonb and time.Time for timestamptz columns
- Add toEntity()/toRelation() converters (UnixMilli + json.Unmarshal)
- Add sqlxTx() helper for wrapping *sql.Tx with sqlx mapper
- Fix ScanDuplicates passing time.Now().Unix() to TIMESTAMPTZ column
- Fix ListEntitiesTemporal missing tenant scope (scopeClause)
- Fix SupersedeEntity missing tenant scope and tenant_id on INSERT
- Fix DedupCandidate.CreatedAt using Unix() instead of UnixMilli()
- Update agents_export_queries.go to reuse new scan row structs
- Net -160 lines of manual scan boilerplate removed

* refactor(store): migrate memory, skills, agents, sessions, mcp, cron, vault stores to sqlx

Batch migration of 19 store files from raw rows.Scan() to
pkgSqlxDB.GetContext/SelectContext with intermediate scan row structs.

Groups migrated:
- Memory: memory_docs, memory_admin, memory_search, memory_embedding_cache
- Episodic: episodic_search, episodic_summaries
- Skills: skills, skills_admin, skills_embedding, skills_export_queries
- Agents: agents (backfill+shares), agents_context, agents_export_team_standalone
- Sessions: sessions_list (List, ListPaged, ListPagedRich)
- MCP: mcp_servers_access, mcp_export_queries
- Cron: cron_exec (GetRunLog)
- Vault: vault_documents (ListDocuments, ftsSearch, vectorSearch)
- Tenant: tenant_configs (ListDisabled, ListAll)

7 new scan row files created. Net -510 lines of manual scan boilerplate.
INSERT/UPDATE/DELETE and scalar COUNT queries kept as raw SQL.

* fix(store): fix 3 sqlx scan struct db tag issues found by audit

- Fix vault FTS alias mismatch: `AS rank` → `AS score` (critical: runtime scan error)
- Fix episodic key_topics type: json.RawMessage → pq.StringArray (TEXT[] column)
- Fix agentShareRow.CreatedAt: string → time.Time, wire to output struct

* feat(providers): implement Wave 2 provider resilience and intelligence

9-phase implementation covering:
- Request middleware chain with composable body transformers
- OpenAI prompt caching, service tier, and fast mode middlewares
- Error classification (9 categories) with two-tier failover
- Model registry with forward-compat resolvers (Anthropic + OpenAI)
- Embedding providers (OpenAI + Voyage) with 1536-dim validation
- Cooldown/probe system with per-provider:model state tracking
- Markdown-aware chunking shared across 5 channels
- Session recall via FTS + pgvector on episodic summaries
- Dreaming/promotion pipeline for long-term memory consolidation

Migrations: 000040 (episodic search index), 000041 (promoted_at column)
Schema version: 39 → 41

* feat(providers): wire model registry into gateway provider construction

Create InMemoryRegistry with Anthropic + OpenAI forward-compat resolvers
at gateway startup. Pass to all Anthropic and OpenAI providers created
from both config and DB sources.

* feat(consolidation): wire DomainEventBus and consolidation pipeline

Create DomainEventBus at gateway startup, thread through resolver →
LoopConfig → Loop → PipelineDeps. Emit session.completed event after
each run finalization. Register consolidation pipeline (episodic →
semantic → KG dedup → dreaming) with event bus subscriptions.

* fix(store): fix episodic key_topics pq.Array, ON CONFLICT, and migration 040 immutability

- episodic_summaries.go Create: json.Marshal(KeyTopics) → pq.Array (text[] column)
- episodic_search.go scanEpisodic/scanEpisodicRow: json.RawMessage → pq.StringArray
- episodic_summaries.go Create: ON CONFLICT add WHERE source_id IS NOT NULL for partial index
- migration 040: add immutable_array_to_string wrapper (array_to_string is STABLE in PG)

* test(store): add 17 integration tests for skills, cron, episodic, tenant configs

- Skills store: 6 tests (CRUD, grants, tenant isolation)
- Cron store: 4 tests (job CRUD, run log sqlx scan, pagination, tenant isolation)
- Episodic store: 4 tests (summary CRUD, list, FTS search, tenant isolation)
- Tenant configs: 3 tests (tool/skill disable, list, tenant isolation)
- Test helper: add cleanup for skills, cron, episodic tables

* fix(permissions): use cron-specific permission check for cron tool (#725)

* fix(security): harden exec path exemption matching (#721)

- Add absolute path exemption for dataDir/skills-store/ (fixes skill
  scripts using absolute paths like /app/data/skills-store/ being denied)
- Strip surrounding quotes before prefix matching (LLMs often quote paths)
- Reject path traversal ("..") in exempt fields to prevent escape
- Switch from "any field exempt → skip" to per-field matching: only exempt
  if ALL fields that match the deny pattern are individually exempt
- Closes pipe/comment bypass vectors where an exempt path in one argument
  would exempt the entire command including non-exempt paths

Includes 27 test cases covering: legitimate access, quoted paths,
path traversal, unicode bypass, pipe/comment bypass, mixed args.

* fix(permissions): use cron-specific permission check for cron tool

Cron tool was hardcoded to check `file_writer` configType via
CheckFileWriterPermission(), ignoring the `cron` configType that
the UI actually saves when granting cron permissions. This caused
agents in group chats to be denied cron access even with correct
permission configured.

Add ConfigTypeCron constant and CheckCronPermission() that checks
`cron` configType first, falling back to `file_writer`.

* fix(chat): load message history on first conversation click (#730)

* fix(chat): load message history when selecting existing conversation from clean state

The skipNextHistoryRef was unconditionally set when sessionKey transitioned
from empty to non-empty. This prevented loadHistory() from running when
clicking an existing conversation from the initial /chat page. The skip
was only intended for the new-chat send flow where the optimistic message
is already displayed.

Guard the skip with expectingRunRef so it only activates when a message
send is in flight.

Closes #729

* docs: add UI diff evidence for PR #730

Before/after screenshots and HTML comparison report showing
first conversation click behavior fix.

* feat(whatsapp): port native WhatsApp channel with whatsmeow from dev

Cherry-pick 0db1e93a with manual conflict resolution:
- cmd/channels_cmd.go: kept dev-v3 HTTP API approach (not config-based)
- go.mod/go.sum: merged deps, ran go mod tidy

* feat(ui): v3 web UI enhancement — branded loading, rich markdown, vault graph, sidebar polish

- Branded loading: HTML pre-loader with logo pulse/shimmer, fade-out on app ready, PageLoader logo swap
- Rich markdown: wikilinks, mermaid (lazy-loaded), math/KaTeX, callouts/admonitions plugins
- Vault graph: force-directed document graph view with table/graph toggle
- Agent filters: type filter (open/predefined) on agents page
- Sidebar: tenant name + role badge in footer
- Query keys: add vault + episodic entries

* fix(ui): address code review — mermaid XSS, Safari compat, cache key

- Change mermaid securityLevel from "loose" to "strict" (XSS prevention)
- Add requestIdleCallback fallback for Safari < 17
- Fix vault all-links query key to use sorted doc IDs (stale cache fix)
- Remove dead abortRef from MermaidBlock
- Add prefers-reduced-motion to loader animation

* docs: update CLAUDE.md with v3 architecture + complete changelog

- Add 10 new v3 internal modules to project structure (pipeline, eventbus, consolidation, tokencount, vault, workspace, etc.)
- Add native WhatsApp channel, edition system, providerresolve, updater to structure
- Update Key Patterns with 8 v3-specific patterns (pipeline, eventbus, 3-tier memory, vault, evolution, orchestration, middleware)
- Add comprehensive V3 Redesign section to changelog covering:
  - 8-stage pipeline with dual-mode gate
  - DomainEventBus + consolidation workers
  - 3-tier memory (working/episodic/semantic)
  - Knowledge Vault with wikilinks
  - Self-evolution engine
  - Orchestration + delegate tool
  - WorkspaceContext resolver
  - ModelRegistry + provider adapter
  - Feature flags
  - Request middleware
  - sqlx migration + 70+ integration tests

* fix(security): harden file path validation, tenant isolation, and tool access

- handleSign: validate path within workspace/dataDir before signing HMAC token
- handleSign: enforce tenant-scoped restriction for RBAC-enabled editions
- handleServe: add workspace/dataDir boundary check for ft= signed requests
- handleServe: remove cross-tenant findInWorkspace fallback for ft= requests
- TenantDataDir/TenantWorkspace: guard against empty slug resolving to parent
- exec tool: add tenants/ to AllowPathExemptions for tenant skill execution
- list_files: add AllowPaths support and wire skills directory access

* docs(v3): update 16 docs + add 2 new docs for v3 architecture

Update all docs/ to reflect v3 implementation (64 commits, 31K insertions):
- 00: architecture overview with 7 new packages
- 01: agent loop with pipeline, orchestration, evolution
- 02: providers with Wave 2 resilience (middleware, failover, registry)
- 03: tools with delegate, vault_search, vault_link, memory_expand
- 04,08,10,11,14,23: targeted v3 additions
- 06: store with 6 new tables, promoted columns, sqlx
- 07: memory with 3-tier architecture, consolidation pipeline
- 18,19: HTTP/WS API with v3 endpoints and methods
- 21: evolution system (metrics, suggestions, auto-adapt)
- model-steering: model registry relationship

New docs:
- 22-v3-http-endpoints.md: 12 v3 HTTP endpoints
- 24-knowledge-vault.md: vault architecture, wikilinks, search

* feat(v3): wire delegate tool, fix pipeline callbacks, clean dead code

Wire delegate tool end-to-end:
- Register DelegateTool in gateway with DelegateRunFunc
- Implement runFn: resolve target agent, build session key, propagate tracing
- Add async announce via msgBus (reuses subagent announce handler)
- Populate context fields (TenantID, Channel, ChatID) for routing
- Set DelegationID + ParentAgentID on RunRequest for event correlation

Fix pipeline callbacks:
- BreakLoop now completes remaining stages in current iteration
- EnrichMedia signature updated to use RunState for message buffer access
- Add non-streaming event emission for channel compatibility
- Fix user message flush tracking in v3 pipeline

Clean dead code (510 LOC removed):
- Delete memory/l1_cache.go, unified_search.go (superseded by vault search)
- Delete vault/auto_injector_impl.go, retriever_impl.go (never wired)
- Delete vault/sync_worker.go (never started)
- Remove orphaned EventMemoryLint, EventSuggestionCreated constants

* feat(v3): finalize stage — emit session.completed, NO_REPLY, strip directives

- Emit session.completed event for consolidation pipeline (episodic → semantic → dreaming)
- Detect NO_REPLY before flush so silent content is persisted for context
- Strip [[...]] message directives from user-facing content (v2 parity)
- Wire StripMessageDirectives, IsSilentReply, EmitSessionCompleted callbacks

* feat(vault): full CRUD — backend endpoints, UI dialogs, content preview

Backend (5 new HTTP endpoints):
- POST/PUT/DELETE /v1/agents/{id}/vault/documents — create, update, delete
- POST/DELETE /v1/agents/{id}/vault/links — create, delete
- Server-side validation for doc_type and scope enums
- Agent ownership verification on link creation
- FK cascade handles link cleanup on document delete

Frontend (React):
- Create document dialog (title, path, type, scope)
- Edit mode in detail dialog (inline title/type/scope editing)
- Delete document with confirmation
- Create link dialog (from/to doc, link type, context)
- Delete link with inline confirmation on badges
- Content preview (collapsible, lazy-loads via /v1/storage/files/)
- Mutation hooks with query invalidation
- i18n keys for en/vi/zh

* fix(v3): critical pipeline parity fixes — ChatRequest, reasoning, passback, media

- Enrich ChatRequest with all provider options (temperature, sessionKey,
  agentID, userID, channel, workspace, tenantID) matching v2
- Add ResolveReasoningDecision for thinking models (o3, DeepSeek-R1, Kimi)
- Wire uniquifyToolCallIDs to prevent OpenAI 400 on duplicate IDs
- Add assistant message passback (Phase, RawAssistantContent) for Anthropic
- Emit block.reply for intermediate content (non-streaming channels)
- Add ContentSuffix append + ForwardMedia merge in FinalizeStage
- Build final assistant message with MediaRefs for session persistence
- Use effectiveMaxTokens() + OptMaxTokens constant
- Guard truncation retry on len(ToolCalls) > 0 + parseError check
- Accumulate ThinkingTokens in usage
- Deduplicate emitRun closure (shared from callbackSet)
- Fix EnrichMedia to receive RunState with actual messages
- Persist user message in makeFlushMessages (matching v2)

* fix(store): coerce NOT NULL JSONB columns to empty object on agent update

When switching provider away from ChatGPT OAuth, the UI sends
chatgpt_oauth_routing: null which violates the NOT NULL constraint.
Coerce null → '{}' for all NOT NULL JSONB promoted columns:
chatgpt_oauth_routing, reasoning_config, workspace_sharing,
shell_deny_groups, kg_dedup_config.

* feat(v3): v3 info modal redesign, agent links CRUD tab, sidebar rename

- Rewrite v3 info modal with 8 feature cards (pipeline, memory,
  retrieval, vault, evolution, orchestration, resilience, registry)
  with v2→v3 comparisons, stat badges, full i18n (en/vi/zh)
- Add tabbed layout to teams page: Agent Teams | Agent Links tabs
- Agent Links tab with full CRUD via existing WS RPC methods
  (list/create/edit/delete) with Radix Select, Combobox, mutual
  agent exclusion in create dialog
- Sidebar menu renamed to "Agent Link & Team"
- Backend: add source_display_name, source_emoji, target_emoji
  to agent link joined queries for consistent display

* fix(store): include personal chats in cron delivery targets

Add 'user' contact_type to ListDeliveryTargets SQL filter in both
PG and SQLite stores. Previously only group/topic contacts appeared
in cron channel/chat dropdowns.

* fix(v3): duplicate messages, missing thinking, span numbering

- ThinkStage: skip AppendPending for final answer (no tool calls),
  let FinalizeStage build the definitive message with sanitization
  and MediaRefs — fixes duplicate assistant messages in session history
- RunResult: add Thinking field, propagate through v2 finalizeRun,
  v3 convertRunResult, run.completed event, and chat.send response
- UI: capture thinkingRef before clearing on run.completed, include
  in final message object so thinking renders without page refresh
- Span numbering: pass Iteration+1 in v3 callback to match v2's
  1-based iteration display in trace span names

* fix(v3): wire delegation targets into BuildSystemPrompt

buildOrchestrationSection() was implemented and tested but never
wired into the actual BuildSystemPrompt() flow. Only the unused
BridgePromptBuilder had it. Add DelegateTargets + OrchMode fields
to SystemPromptConfig and inject "## Delegation Targets" section
so agents with agent_links see their delegation targets in prompt.

* fix(v3): sync mediaResults from bridgeRS to pipeline state

syncBridgeToState copied loopKilled, asyncToolCalls, deliverables
from the v2 bridgeRS but missed mediaResults. Tool results with
MEDIA: prefix were extracted by processToolResult into bridgeRS
but never propagated to state.Tool.MediaResults — causing
FinalizeStage to produce empty MediaRefs and RunResult.Media.

* fix(v3): populate SessionCompletedPayload in session.completed events

Both v2 loop and v3 pipeline emitted session.completed events with
nil Payload, causing episodicWorker type assertion to fail silently.
Episodic summaries were never created.

- Expand EmitSessionCompleted callback to pass msgCount, tokensUsed,
  compactionCount from pipeline state
- V3 path: build payload from state.Messages.TotalLen(),
  state.Think.TotalUsage, state.Compact.CompactionCount
- V2 path: build payload from history + rs.totalUsage +
  sessions.GetCompactionCount()

* fix(v3): remaining pipeline parity gaps — skill postscript, team task count

- Add SkillPostscript callback to PipelineDeps + FinalizeStage,
  matching v2's skill evolution nudge after complex tool runs
- Wire makeSkillPostscript() in adapter with same logic as v2
  (skillEvolve + skillNudgeInterval + totalToolCalls threshold)
- Sync teamTaskCreates from bridgeRS to pipeline EvolutionState
  (was already syncing teamTaskSpawns but missed creates)

* fix(evolution): add JSON struct tags to metric aggregates

ToolAggregate and RetrievalAggregate had no JSON tags, causing
Go to marshal field names as PascalCase (ToolName, CallCount)
while the UI expects snake_case (tool_name, call_count). Charts
rendered empty containers with no data bars.

Also change AvgDuration (time.Duration) to AvgDurationMs (float64)
for JSON-friendly serialization — time.Duration marshals as
nanoseconds which is unusable in frontend.

* fix(v3): add debug logging to episodic worker for consolidation pipeline

Add INFO/WARN logs at entry, summary decision, and creation points
to diagnose why episodic_summaries table stays empty in production.

* chore: silence noisy tenant_cache debug logs

* refactor(ui): replace v3 settings section with engine version picker + tabbed info modal

Replace flat toggle list with radio-style version cards (v2/v3) and
feature mini-cards. Redesign v3 info modal from single scroll to 3-tab
layout (Core Engine, Memory & Knowledge, Orchestration) with Lucide
icons and v2→v3 comparison cards.

- Add batchUpdate to use-v3-flags hook for atomic v2 switch
- Create engine-version-section with VersionCard + FeatureMiniCard
- Create v3-info-modal/ with 5 modular components (<45 LOC each)
- Add i18n keys (detail.engine + v3Info.tabs) for en/vi/zh
- Wire into agent-overview-tab, agent-header, agent-card
- Delete v3-settings-section.tsx + agent-v3-info-modal.tsx

* feat(v3): pass media files through delegate tool results

Delegate tool now carries media files (images, audio, etc.) produced
by the delegatee back to the parent agent. DelegateRunFunc returns
DelegateResult{Content, Media} instead of plain string.

- Add DelegateResult struct with Content + Media fields
- Convert agent.MediaResult to bus.MediaFile in gateway wire
- Attach media to sync result and async announce message
- Add MediaCount to DelegateCompletedPayload for observability
- Set MetaParentAgent in async announce metadata

* merge: bring main bug fixes into dev-v3

Cherry-pick 8 commits from origin/main:
- fix(telegram): handle group-to-supergroup migration (#698)
- feat(providers): add OpenRouter identification headers (#705)
- fix: deterministic prompt ordering for LLM cache hit (#719)
- fix(security): harden exec path exemption matching (#721)
- fix: invalidate storage size cache on delete and move (#726)
- fix: use errors.Is() for sentinel comparisons (#727)
- fix(desktop): add defaultValues to form dialogs (#737)
- Release: credential resolver, WhatsApp native, exec hardening (#754)

Conflict resolution:
- store/pg exports: accept main's errors.Is() additions
- shell.go: accept main's extracted matchesAnyPathExemption helper
- gateway_providers: merge both WithAnthropicName + WithAnthropicRegistry
- loop_types + resolver: merge v3 fields (OrchMode, DelegateTargets,
  EvolutionMetricsStore) with main's new UserResolver/ContactStore
- gateway_setup: keep dev-v3's tenant-scoped path exemptions
- channels_cmd: keep dev-v3's HTTP API approach

* feat(v3): add foundation packages for architecture refactor (Phase 1)

Purely additive — zero changes to existing files. Creates shared types
and helpers that Phase 2-4 will migrate callers to:

- internal/store/base/: Dialect interface, BuildMapUpdate, nullable/JSON
  helpers, scope clause builder, table metadata (44 tests)
- internal/orchestration/: ChildResult capture from v2/v3, media type
  conversion with round-trip tests (10 tests)
- internal/providers/sse_reader.go: Shared SSE scanner replacing inline
  bufio.Scanner boilerplate in 3 providers (8 tests)

* refactor(store): unify pg/ and sqlitestore/ helpers via base/ package (Phase 2)

- Create PG and SQLite dialect implementations (base.Dialect interface)
- Replace 15 duplicate helpers in pg/helpers.go with aliases to base.*
- Replace 13 duplicate helpers in sqlitestore/helpers.go with aliases
- Rewrite execMapUpdate and execMapUpdateWhereTenant to use
  base.BuildMapUpdate with dialect-specific placeholders
- Rewrite scopeClause/scopeClauseAlias as thin wrappers around
  base.BuildScopeClause
- Remove duplicate execMapUpdateWhereTenant from pg/agents.go

pg/helpers.go: 267→175 LOC, sqlitestore/helpers.go: 226→130 LOC

* refactor(orch): extract BatchQueue[T] generic for announce queues (Phase 3)

- Create internal/orchestration/batch_queue.go: generic producer-consumer
  queue replacing duplicated sync.Map+mutex pattern (10 tests, race-safe)
- Simplify cmd/gateway_announce_queue.go: team queue uses BatchQueue,
  removes announceQueueState/getOrCreate/drain/tryFinish (~40 LOC saved)
- Simplify cmd/gateway_subagent_announce_queue.go: subagent queue uses
  BatchQueue, same pattern reduction (~40 LOC saved)
- Update cmd/gateway_consumer_handlers.go: callers use new signatures

* fix: remove defer accumulation in announce loop, clean comment tombstone

- Remove `defer ptd.ReleaseTeamLock()` inside for loop that accumulated
  deferred calls per iteration (explicit ReleaseTeamLock already called)
- Remove dead comment tombstone in pg/agents.go

* fix: scope defer in announce loop via closure for panic safety

Wrap announce processing in closure so defer ptd.ReleaseTeamLock()
runs once per iteration instead of accumulating. Explicit release
still called for normal path; defer catches panics.

* refactor(providers): wire shared SSEScanner into 3 providers (Phase 4b)

Replace inline bufio.Scanner+SSE parsing boilerplate with shared
SSEScanner from sse_reader.go in:
- openai.go: data-only SSE (OpenAI, DashScope, Kimi)
- codex.go: data-only SSE (OpenAI Codex)
- anthropic_stream.go: event+data SSE (uses EventType() for switch)

Removes ~24 LOC of duplicated scanner setup + manual line parsing.

* refactor(agent): force v3 pipeline, remove v2 runLoop (Phase 4A)

- Delete runLoop() from loop.go (~745 LOC removed), keep shared helpers
  (resolveToolCallName, hasParseErrors, truncateToolArgs)
- Remove v2/v3 gate in loop_run.go: always call runViaPipeline()
- Remove v3PipelineEnabled field from Loop struct + LoopConfig + resolver
- Always resolve workspace in loop_context.go (was behind v3 gate)
- Deprecate PipelineEnabled in V3Flags (kept for backward compat parsing)

All agents now always use v3 pipeline. No behavioral change for agents
that already had v3_pipeline_enabled=true (which was all production agents).

* refactor(gateway): decompose gateway.go from 1295 to 476 LOC (Phase 4B)

Extract sections of runGateway() into focused files:
- gateway_deps.go: gatewayDeps struct for shared state
- gateway_http_wiring.go: wireHTTPHandlersOnServer (~207 LOC)
- gateway_events.go: event subscribers + teamTaskEventType (~367 LOC)
- gateway_lifecycle.go: signal handling, shutdown, server start (~222 LOC)
- gateway_tools_wiring.go: cron/heartbeat/session tool wiring (~116 LOC)

Also extracted: startCronAndHeartbeat, makeDelegateAnnounceCallback.
Pure structural refactoring — no behavior change.

* test(agent): add v3 force migration guard tests

Verify v2 runLoop is deleted, V3PipelineEnabled field removed from
LoopConfig, and V3Flags backward compat parsing still works.
Compile-time guards prevent accidental re-introduction of v2 code.

* feat(delegate): wire ChildResult + fix media passthrough (Phase 3 gap)

- Use orchestration.CaptureFromRunResult in delegate run callback
  to standardize result capture via ChildResult
- Use MediaResultToBusFiles in CaptureFromRunResult (DRY)
- Fix delegate_tool.go metadata key: delegate_id → delegation_id

* refactor(ui): remove v2/v3 pipeline toggle, always show V3 (Phase 4E)

- engine-version-section.tsx: remove pipeline toggle, show V3 read-only
- use-agent-version.ts: always return "v3" (no flag check)
- use-v3-flags.ts: remove v3_pipeline_enabled from toggleable flags
- Update i18n strings (en/vi/zh): remove v2-specific tooltip text

* test: add Phase 5 test infrastructure for v3 architecture refactor

- pg/pg_dialect_test.go: 4 tests for PG Dialect (placeholder, transform,
  returning, interface compliance)
- sse_reader_test.go: 4 edge case tests (empty data, scanner error,
  event type persistence, no data after [DONE])
- gateway_announce_format_test.go: 10 tests for team + subagent
  announce formatting (single/batch, success/failure, snapshot)

Coverage: base/ 96%, orchestration/ 100%, providers/ 57%

* chore: remove stale runLoop references + apply go fix (Phase 6)

- Update comments referencing deleted runLoop in pipeline callbacks,
  loop_types, stage.go
- go fix: reflect.TypeFor, range over int, strings.Builder

* docs: update architecture docs for v3 refactor completion (Phase 6)

- CLAUDE.md: add store/base/, orchestration/ to project structure;
  remove v2 runLoop and dual-mode gate references; rename Pipeline (v3)
  to Pipeline; add SSEScanner and BatchQueue to key patterns
- docs/00-architecture-overview.md: update module map with new packages,
  remove [V3] markers (now standard)
- docs/17-changelog.md: add V3 Architecture Refactor entry (6 phases)

* feat(evolution): skill draft auto-generation + go fix cleanup

- Add skill draft template generation from evolution suggestions
- Wire skill apply endpoint in evolution HTTP handlers
- Apply go fix across codebase (range-over-int, reflect.TypeFor, etc.)
- Minor refactors: simplify switch/case, reduce string builder allocs
- Gateway deps: add skills loader field

* perf(prompt): deterministic tool order + Anthropic cache boundary split

Sort tool names in buildToolingSection for cache-stable output.
Insert GOCLAW_CACHE_BOUNDARY marker before Time section; Anthropic
provider splits system prompt into 2 blocks (stable cached, dynamic not).
Backward compat: no marker → single cached block.

* perf(prompt): optimize cache boundary position + add Execution Bias

Move Memory Recall and stable context files (AGENTS.md, TOOLS.md,
USER_PREDEFINED.md) above cache boundary. Dynamic per-user files
(USER.md, BOOTSTRAP.md) stay below. Add Execution Bias section
(full mode only) forcing action-oriented tool use. Fix duplicate
header when Project Context split across boundary.

* feat(prompt): add PromptMode task/none + 3-layer resolution

Expand PromptMode from full|minimal to full|task|minimal|none.
Task mode = enterprise automation: keeps Tooling, Execution Bias,
Safety-slim, Persona-slim, Skills-search, MCP-search, Memory-slim,
Workspace, Runtime, Delegation. Drops verbose sections (Tool Call
Style, Self-Evolution, Spawning, Recency, etc.).

None mode returns identity line only. 3-layer mode resolution:
runtime override > auto-detect (subagent/cron) > agent config
(other_config.prompt_mode) > default (full).

* feat(prompt): provider prompt contributions (stable/dynamic/overrides)

Add PromptContribution struct + PromptContributor interface for
provider-specific prompt customizations. Providers can inject
StablePrefix (before cache boundary), DynamicSuffix (after boundary),
or override sections by ID (e.g. execution_bias). Nil-safe: providers
that don't implement the interface get default behavior.

* feat(prompt): pinned skills with hybrid inline+search mode

Add per-agent pinned_skills config (max 10, from other_config JSONB).
Pinned skills always inline in prompt via BuildPinnedSummary.
Non-pinned discovered via skill_search. Hybrid section shows both
pinned XML and search instructions. Works in full and task modes.

* fix(prompt): validate prompt_mode from DB before cast

Reject unknown prompt_mode values from OtherConfig JSONB
(e.g. typos like "taks") by checking against validPromptModes set.
Invalid values default to "" (full mode). Prevents broken prompts
where no mode flags match.

* fix(prompt): wire SectionIDToolCallStyle for provider override

Tool Call Style section now uses sectionContent() like Execution Bias,
allowing providers to override it via PromptContribution.SectionOverrides.

* feat(store): implement 9 SQLite store backends for v3 parity

Close feature gap between PostgreSQL and SQLite (desktop/lite) editions.
96 methods across 9 stores: AgentLinks, SubagentTasks, SecureCLI,
SecureCLIGrants, EvolutionMetrics, EvolutionSuggestions, Episodic,
KnowledgeGraph, Vault. Schema v8→v9 adds 4 tables.

Key design decisions:
- LIKE-based search replaces tsvector/FTS5 (unavailable in modernc.org/sqlite)
- Go-side StringSimilarity for KG dedup (replaces pgvector cosine)
- Recursive CTE traversal with comma-delimited path cycle detection
- AES-256-GCM encryption on all SecureCLI read/write paths
- F15: SecureCLI disabled when EncryptionKey empty
- ON CONFLICT DO UPDATE (never INSERT OR REPLACE) to preserve FK cascades

* docs(store): add SQLite parity section to store data model docs

Document 9 new SQLite store implementations, schema v9, and
feature parity gaps (LIKE vs FTS, Jaro-Winkler vs vector dedup).

* fix(docker): skip web-builder stage when ENABLE_EMBEDUI=false

Use BuildKit conditional stage pattern so web-builder is not executed
when embedding is disabled. Also update pnpm-lock.yaml for 6 new deps
that were missing from the lockfile (markdown/math/mermaid packages).

* feat(vault): embed metadata.summary for richer vector search

Include summary from metadata JSONB in embedding text (title + path +
summary) for better semantic search. Update tsvector generated column
to include summary in FTS index. Zero new columns — summary stored in
existing metadata JSONB field. Backward compat: docs without summary
still embed title+path only.

* fix(vault-ui): wider detail dialog, markdown rendering, create tooltip

- Detail dialog: sm:max-w-lg → sm:max-w-2xl, content area 200→300px
- Content preview: render markdown via MarkdownRenderer instead of <pre>
- Create button: add tooltip explaining "select agent first" when disabled

* feat(ui): prompt_mode dropdown + pinned_skills multi-select

Add PromptSettingsSection to agent overview tab:
- prompt_mode: Select dropdown (full/task/minimal/none)
- pinned_skills: Tag input with max 10, click to remove
Both save to agent other_config JSONB via existing onUpdate flow.
Self-contained save button appears only when values change.

* fix(vault-ui): enlarge dialog to max-w-4xl, constrain markdown heading sizes

Dialog sm:max-w-2xl → sm:max-w-4xl. Markdown headings capped at
text-base/text-sm via Tailwind child selectors to prevent oversized
h1/h2 in content preview. Content area raised to 400px.

* refactor(ui): move pinned skills to dedicated section with skill select

Split pinned_skills out of PromptSettingsSection into PinnedSkillsSection.
Uses useAgentSkills hook for proper dropdown with granted skills list.
Placed right below SkillsSection in agent overview tab. Badge chips
with X to remove, Select dropdown to add. Max 10 enforced.

* fix(ui): add border wrap to capabilities section for visual consistency

* feat(ui): redesign prompt mode as compact cards, replace v3 badge

- Rewrite prompt settings from select dropdown to 2×2 compact cards
  with lucide icons (Zap/Wrench/Package/CircleOff) and ring selection
- Move prompt settings to top of agent overview tab
- Replace v3 badge with prompt mode badge in header, card, and list row
- Add i18n keys for prompt mode labels/descriptions (en/vi/zh)
- Extract readPromptMode() to shared agent-display-utils
- Remove dead useAgentVersion hook and v3Tooltip/v2Tooltip i18n keys
- Remove v3 badge from EngineVersionSection (keep feature toggles)
- Use cn() for badge class composition with twMerge safety

* feat(ui): add section tags and token estimates to prompt mode cards

Each card now shows which system prompt sections are included
(Persona, Tools, Safety, Skills, MCP, Memory, etc.) as compact
tags, plus estimated base token range (~2-4K for full, ~10 for none).
Helps users understand the impact of each mode at a glance.

* fix(ui): correct token estimates with actual tiktoken measurements

Measured via tiktoken (cl100k) on realistic config:
full=~1.7K+, task=~1.1K+, minimal=~660, none=~6 base tokens.
The "+" suffix indicates context files/skills/MCP add more.

* fix(ui): use tiktoken-measured token ranges for prompt mode cards

Measured across 3 scenarios (bare/typical/heavy) via tiktoken cl100k:
full=~500-2.9K, task=~350-1.2K, minimal=~350-820, none=~6 tokens.
Ranges reflect real configs from minimal (3 tools) to heavy
(10 tools, long persona, MCP, sandbox, pinned skills).

* fix(ui): use production-measured token counts for prompt mode cards

Measured via tiktoken on real production agent (tieu-ho) with
4 context files (AGENTS.md, SOUL.md, IDENTITY.md, USER_PREDEFINED.md),
14 tools, memory, KG, skills, Telegram channel:
full=~3.1K, task=~2.2K, minimal=~1.9K, none=~6 tokens.

* refactor(ui): accurate section tags per prompt mode from systemprompt.go

Section tags now match exact gating logic in BuildSystemPrompt():
- full: persona, tools, exec bias, call style, safety, skills,
  MCP, memory, sandbox, evolution, channel hints (11 sections)
- task: style echo, tools, exec bias, safety (slim), skills (search),
  MCP (search), memory (slim) (7 sections)
- minimal: tools, safety (2 sections + shared context files)
- none: no tags shown, no token count (trivially ~6 tokens)

Removed workspace/identityOnly tags (shared across all modes).

* feat(ui): replace engine version toggles with V3 capabilities modal

- Remove 3 toggle switches (Pipeline, Memory, Retrieval) from agent
  detail — all features are now always-on for v3 agents
- Replace with compact static badges layout
- New V3 Capabilities modal with 4 tabs:
  Pipeline (8-stage flow), Memory (L0/L1/L2 tiers),
  Knowledge (KG, Vault, Dreaming), Orchestration (Delegate, Evolution)
- Each tab has Lucide icons and technical descriptions of how
  features actually work
- Separate i18n namespace v3-capabilities in en/vi/zh locales

* refactor(ui): move V3 badge to agent header, remove engine version section

- Add clickable V3 badge next to agent name in header
- Clicking opens V3 Capabilities modal
- Remove Engine Version section from overview tab entirely
- Remove unused EngineVersionSection import

* feat: v3 prompt engine overhaul — 7-phase restructuring

Phase 1: Fix mode resolution — subagent/cron cap at task (not minimal),
heartbeat stays minimal, pinned skills injected in all modes, USER_PREDEFINED
added to minimal allowlist.

Phase 2: Context file restructuring — new CAPABILITIES.md (domain expertise,
separated from SOUL.md), AGENTS_MINIMAL.md for heartbeat sessions, both added
to stable context files and minimal allowlist.

Phase 3: Summoner update — all 4 prompt builders generate CAPABILITIES.md,
fallback 2-call stores capabilities alongside SOUL.md.

Phase 4: Open agent deprecation — creation silently upgrades open→predefined
in both HTTP and WS endpoints.

Phase 5: Bootstrap auto-contact — sender name from channel metadata injected
into bootstrap context for 1-turn onboarding (DM only).

Phase 6: System prompt preview — GET /v1/agents/{id}/system-prompt-preview
endpoint with mode param, token counting, section parsing.

Phase 7: Agent creation UX — removed open agent type toggle, schema simplified,
description always required, prompt mode cards updated with v3 token estimates.

* fix(vault-ui): redesign detail dialog and link dialog UX

- Vault detail: show content preview by default (not collapsed),
  move type/scope to header badges, hash to subtle footer
- Link dialog: replace native <select> with searchable Combobox
  for target document and link type (5 presets + custom)
- Fix Vietnamese i18n: add proper diacritics to v3-capabilities

* fix(i18n): keep prompt section badges in English across all locales

Technical terms like Persona, Tools, Safety, Memory, Skills, MCP,
Sandbox, Evolution should not be translated — they are UI labels
matching system prompt section names.

* feat(ui): system prompt preview in Files tab + README restructure

Files tab: add "System Prompt" item in sidebar below context files.
When selected, shows readonly preview with mode selector (full/task/
minimal/none), token count badge, and cache boundary highlighting.
Fetches from GET /v1/agents/{id}/system-prompt-preview.

README: remove Claw Ecosystem comparison tables, remove OpenClaw port
reference, rename "What Makes It Different" to "Core Features" with v3
additions (8-stage pipeline, 4-mode prompt, 3-tier memory, knowledge
vault, self-evolution), slim built-in tools to category summary table.

* feat: replace architecture images with v3 sketchnotes

Add 9 new architecture sketchnote images generated for v3:
- 8-Stage Agent Pipeline
- 4-Mode Prompt System
- 3-Tier Memory Architecture
- Multi-Tenant Architecture
- Agent Orchestration
- Knowledge Vault
- Provider Adapter System
- Self-Evolution System
- DomainEventBus

Remove old architecture images (architecture.jpg, goclaw_multi_tenant.png,
agent-delegation.jpg, agent-teams.jpg).

Update README to reference new images in Architecture and Orchestration
sections. Consolidate orchestration section (remove separate delegation
and teams subsections).

* feat(readme): add remaining 4 architecture sketchnotes with sections

Add Knowledge Vault, Self-Evolution, Provider Adapters, and Event-Driven
Architecture sections with corresponding sketchnote images and concise
descriptions. All 9 v3 architecture diagrams now in README.

* feat: reorder README architecture images, evolution guardrails fix, memory tools enhancement

README: reorder architecture sketchnotes (Multi-Tenant first), remove
pinnedSkills from task mode sections badge.

Backend: evolution guardrails fix, memory auto-injector and tools
enhancement, gateway HTTP wiring update.

* feat(desktop): add 12 v3 feature sections to agent detail panel

Add evolution expansion (skill learning, v3 flags), prompt mode selector,
evolution dashboard tab (CSS bar charts, suggestions, guardrails),
thinking/reasoning config, orchestration display, context pruning,
compaction, subagents (lite-limited), tool policy, sandbox config,
and pinned skills management.

Extract agent detail state into use-agent-detail-state hook.
Add getWithParams to ApiClient. Add i18n keys to en/vi/zh locales.

* fix(vault): team-scope security — prevent cross-team data corruption and leaks

- Add team_id UUID + custom_scope to vault_documents (PG migration 043, SQLite migration 10)
- COALESCE-based UNIQUE prevents silent cross-team data overwrite on ON CONFLICT
- PG trigger auto-corrects scope…

* ci(release): switch from auto-deploy to tag-based release

Replace go-semantic-release (auto on push main) with tag-based trigger:
- Push tag v1.2.3 → auto release (stable only, not beta/rc)
- Manual dispatch with optional tag input as fallback
- gh release create with --generate-notes replaces semantic-release changelog
- Beta/RC tags still handled by release-beta.yaml (unchanged)

* fix(ci): resolve 4 workflow failures — tests, race, Windows build

- slack: update splitAtLimit tests to match ChunkMarkdown behavior
- providerresolve: use ChatGPTOAuthRouting field instead of OtherConfig
- scheduler: buffer started channel to prevent race in DropOldPolicy
- backup: split checkDiskSpace into platform files (Unix/Windows)

* feat(vault): modal document view, compact sidebar, non-owner team access

UI:
- Replace bottom detail panel with modal dialog for all doc views
- Redesign sidebar with type icons, compact layout, inline metadata
- Always show team select, fix missing load() call for teams hook
- Align header heights between sidebar and main panel

Backend:
- Add TeamIDs filter to VaultListOptions and VaultSearchOptions
- Non-owner users now see personal + their teams' docs (was personal-only)
- Refactor PG search to use searchTeamFilter for FTS and vector queries
- Update both PG and SQLite stores with shared team filter helpers

* fix(backup): guard nil context in checkPgDump preflight

* feat(channels): add Facebook Messenger and Pancake channel integrations (#731)

Add two new channel implementations for Facebook Fanpage (comment + Messenger
auto-reply, first inbox DM) and Pancake/pages.fm (multi-platform inbox via
Facebook, Zalo, Instagram, TikTok, WhatsApp, LINE).

Key features:
- Facebook: comment auto-reply, Messenger auto-reply, first inbox DM,
  HMAC-SHA256 webhook verification, multi-page webhook routing
- Pancake: multi-platform inbox, outbound echo dedup with HTML normalization,
  race-condition-safe echo fingerprinting, platform-aware formatting
- Bootstrap skip: pre-fill USER.md from channel metadata (Pancake)
- SanitizeDisplayName across all channels (defense in depth)

Code audit fixes:
- Fix truncateForTikTok byte→rune slicing (UTF-8 corruption)
- Fix empty message.ID shared dedup slot (silent message loss)
- Fix DisplayName markdown injection in buildPrefilledUser
- Consolidate duplicate ChannelMeta type (agent→bootstrap)
- Compile-time interface assertions, alphabetical type constants
- Per-message logs demoted to slog.Debug, errors.As for wrapped errors
- UI: alphabetical channel ordering, complete config schemas
- Remove deprecated WhatsApp bridge_url, fix nested error parsing

* Delete plans/260406-1304-goclaw-v3-core-design directory

* fix(vault): adaptive label truncation and zoom-aware link labels in graph view

Node labels now truncate based on zoom level (10→18→30→full chars),
showing full text only when zoomed in close enough to read.
Link labels hidden below 1.5x zoom to reduce visual clutter.
Selected nodes always show full label regardless of zoom.

* refactor(vault): remove vault_link/vault_backlinks tools, auto-sync wikilinks in enrichment pipeline

- Remove vault_link and vault_backlinks builtin tools (replaced by auto-linking)
- Add DeleteDocLinksByType to VaultStore interface (PG + SQLite) to selectively
  delete links by type without destroying semantic links
- Integrate SyncDocLinks into enrichment worker: [[wikilinks]] are now
  auto-extracted from document content and synced as vault links on every write
- Fix SyncDocLinks to use DeleteDocLinksByType("wikilink") instead of
  DeleteDocLinks which was deleting all link types including semantic
- Add missing coreToolSummaries for delegate, memory_expand, vault_search
  (previously showed as "(custom tool)" in system prompt)
- Increase enrichSimilarityLimit from 5 to 10 for richer auto-linking

* fix(ui): persist chat messages across sessions and fix first-message drop

Migrate chat message state from component-local useState to a Zustand
store so messages survive session switches and back-navigation.

- Infinite re-render loop (React #185): inline `?? []` fallback in
  Zustand selector created a new array reference every render; fixed
  with a stable EMPTY_MESSAGES module constant.
- First message disappearing in new chat: addLocalMessage used the
  component-level sessionKey which is still "" when send fires
  (navigate is async); fixed by threading explicit sessionKey through
  onMessageAdded in useChatSend.

* fix(ui): add LRU eviction to chat messages store

Keep at most 25 cached sessions in memory. When the limit is exceeded,
evict the oldest idle sessions (never evict sessions with an active run).

* feat(vault): replace auto-linking with LLM-classified relationship types

Replace vector-similarity-only auto-linking (creating generic "semantic"
links) with an LLM classification step that determines actual relationship
types (reference, depends_on, extends, related, supersedes, contradicts)
and generates meaningful context descriptions.

- Add enrich_classify.go: orchestration, retry with escalating timeouts,
  candidate gathering with bidirectional dedup, 20-doc cap per batch
- Add enrich_classify_prompt.go: system prompt, JSON parsing with partial
  success model, UTF-8 safe truncation
- Restructure processBatch: summarize → embed → classify → dedup+wikilinks
- Move dedup recording after classify (failed classify allows re-enrichment)
- Remove autoLink method (fully replaced by classifyLinks)
- Add DeleteDocLinksByTypes to VaultStore interface + PG/SQLite (IN clause)
- Guard old link deletion behind len(newLinks) > 0 (no data loss on all-SKIP)

* fix(evolution): fix 7 bugs in evolution flow — guardrails, cron, dedup, dead types

- Remove broken delta comparison in CheckGuardrails (compared usage rate vs max delta)
- Replace hardcoded +0.05 threshold bump with configurable MaxDeltaPerCycle, cap at 0.95
- Remove dead MetricFeedback and SuggestMemoryPrune constants + UI references
- Make SuggestToolOrder approval actionable — disables tool via BuiltinToolTenantConfigStore
- Replace time.Ticker(24h) with wall-clock scheduling (3 AM daily, Sundays weekly eval)
- Add PG advisory lock on pinned connection for multi-instance safety
- Add EvolutionSuggest flag check in cron (metrics-only agents skip suggestion analysis)
- Change suggestion dedup from type-only to (type, metric_key) composite key

* fix(tracing): include thinking tokens in cost calculation

CalculateCost previously ignored usage.ThinkingTokens entirely, causing
cost underestimation for every reasoning-capable model (OpenAI o3/o4-mini,
Codex/GPT-5, Anthropic extended thinking).

Thinking tokens are reported by providers as a sub-count of completion
tokens — OpenAI completion_tokens already includes reasoning_tokens,
Codex output_tokens likewise, and Anthropic output_tokens counts thinking
at the output rate. Default behaviour (ReasoningPerMillion=0) now matches
provider billing semantics: full CompletionTokens priced at OutputPerMillion,
no double-counting.

When ReasoningPerMillion is explicitly configured, the completion bucket is
split into visible output + thinking and each priced independently. Defensive
clamp to zero when Anthropic's thinkingChars/4 estimate exceeds reported
OutputTokens.

Adds ReasoningPerMillion field to ModelPricing and 7 regression tests
covering the double-count gate, distinct-rate split, Anthropic estimate
overrun, and backward compatibility for non-reasoning models.

* feat(pipeline): per-provider context window, cache/tenant/pipeline hardening

Ship Group A (bug fixes) + Group B (pipeline enhancements) from
plans/260410-1009-openclaw-ts-feature-port — five changes that share
cmd/ wiring and pipeline plumbing so they commit as a unit.

cache: InMemoryCache now supports periodic sweep + max-size cap via
variadic options. PermissionCache wires 60s sweep + 10k entry cap +
Close() hook in gateway shutdown so long-running gateways don't leak
per-user permission entries. Backward compatible for zero-arg callers.

store: ContactCollector.seen cache key now includes tenant_id + channel_
instance so the same sender in different tenants (or different bot
instances in the same tenant) no longer silently skip upserts against
each other. Zero-tenant (Desktop) behaviour preserved.

pipeline: EffectiveContextWindow is resolved once per run in ContextStage
via a ResolveContextWindow callback (backed by providers.ModelRegistry)
so PruneStage bills history against the actual model window instead of
a stale static config. Nil resolver / unknown model fall back to
Config.ContextWindow for backward compatibility. Locked to the model
observed at context build time to prevent mid-run budget drift.

pipeline: PipelineConfig.ReserveTokens carves out an optional safety
buffer subtracted from the history budget so compaction fires slightly
before the hard limit — protects against provider over-delivery and
token counter drift on streaming responses. Zero (default) preserves
legacy budget math.

agent: ModelRegistry flows gateway → ResolverDeps → LoopConfig → Loop →
pipeline adapter so resolver can look up per-model capabilities at run
time without re-touching gateway internals.

20 regression tests across cache, contact collector, and pipeline cover
the critical paths: cross-tenant isolation, cache sweep + eviction +
Close idempotency, per-model window override + fallback, and reserve
token buffer behaviour. All passing with -race on both go build ./...
and go build -tags sqliteonly ./....

* feat(memory): context-aware recall query for auto-inject

Auto-inject previously searched episodic memory using only the latest
user message. Follow-up questions like "what's my favorite?" returned
poor matches because the embedding lost the conversational frame.

InjectParams now carries an optional RecentContext field that pgAuto
Injector prepends to the search query as "Context: ... \nQuery: ..."
before running the FTS+vector hybrid search. The "Context:"/"Query:"
framing works with both instruction-tuned embedding models (which
respect the labels) and plain models (neutral separators).

ContextStage walks the message history backward, collects up to 2
trailing user turns capped at 300 runes total, and threads the snippet
through the AutoInject callback to the injector. Empty RecentContext
preserves legacy single-message search semantics — zero-risk fallback
for callers that haven't adopted the new field.

Rune-based truncation (not byte) keeps vi/zh locales safe: a byte-wise
tail-clip would slice multi-byte runes and emit invalid UTF-8 to the
embedding model, degrading exactly the cases Phase 9 is meant to fix.
tailClipRunes helper covers Vietnamese, Chinese, Japanese, emoji.

13 regression tests: recall query builder (unicode-safe clip,
whitespace handling, position ordering), buildRecentContext (order
preservation, turn cap, truncation, non-user skip), and
tailClipRunes (CJK, short input, zero cap). All passing with -race.

Refs plans/260410-1009-openclaw-ts-feature-port/phase-09-active-
memory-recall.md — minimal-viable delivery; Tier 2 LLM re-ranking
and per-session recall cache deferred until operational data shows
context-aware search alone is insufficient.

* feat(ui/graph): migrate vault + KG graph to Sigma.js + Graphology

Replace react-force-graph-2d (Canvas 2D, 500-node ceiling) with Sigma.js
(WebGL, 5k+ nodes at 60fps) for vault and knowledge graph visualization.

Layout pipeline uses Louvain community detection + grid seeding + FA2
refinement + noverlap post-processing. Communities are placed in a grid
(sorted by size) so related nodes cluster visually instead of collapsing
into a ring shape.

Shared graph infrastructure in ui/web/src/components/graph/:
- sigma-graph-container: lifecycle, synchronous pre-computed layout,
  2-hop BFS highlight on hover, opacity edge pulse, prefers-reduced-motion
- sigma-graph-controls: reusable zoom/stats bar with camera tracking
- sigma-graph-search: combobox with ARIA wiring and keyboard navigation
- sigma-graph-filters: type filter dropdown (outside-click + Escape)
- sigma-graph-minimap: canvas overlay with viewport rect + click-to-jump
- sigma-graph-keyboard-help: help popover triggered by ? key
- use-sigma-keyboard: +/- R F Esc / shortcuts
- graph-utils: sizing, middle-truncation helpers

Adapters rewritten to output Graphology Graph instances. Both views use
curved arrow edges, focus ring for keyboard users, role="application"
ARIA, responsive top bar, and node limits up to 5k.

Removes react-force-graph-2d, d3-force, @types/d3-force.
Adds sigma, @sigma/edge-curve, graphology, graphology-layout,
graphology-layout-forceatlas2, graphology-layout-noverlap,
graphology-communities-louvain, graphology-types.

* feat(vault): workspace rescan endpoint with symlink-safe walker

Add POST /v1/agents/{agentID}/vault/rescan to backfill vault_documents
from filesystem. Walks agent workspace, registers missing/changed files,
publishes enrichment events for async summarize + embed + link classify.

Backend:
- SafeWalkWorkspace: symlink-safe walker with exclusion patterns,
  resource limits (5K files, 500MB, 50MB/file), context deadline
- RescanWorkspace: hash-based dedup, path-based scope detection
  (teams/{id}/ → team scope), idempotent via UpsertDocument ON CONFLICT
- Per-agent mutex (409 Conflict for concurrent rescans)
- Tenant-scoped workspace resolution (config.TenantWorkspace)
- Enrichment worker: semaphore-based parallel summarize (max 3 concurrent)
- Media files without summary skip LLM summarize, embed title+path only
- DRY: export InferTitle/InferDocType from vault pkg, remove from interceptor
- Auto-register text uploads in vault via onTextUploaded callback

Frontend:
- Rescan button in vault page header (FolderSync icon)
- Toast with result counts, 409 warning, error handling
- i18n strings for en/vi/zh

Security: skip all symlinks, boundary checks, per-file size limit,
tenant isolation via server-side workspace resolution.

* feat(ts-port): reasoning strip, dreaming config + weighted scoring

Phase 6 — Reasoning token stripping:
- ReasoningDecision.StripThinking auto-flags Kimi + DeepSeek-Reasoner
- Guard clauses in Anthropic/OpenAI/Codex stream handlers
- Usage.ThinkingTokens + RawAssistantContent preserved (billing + tool passback safe)

Phase 8 — Per-agent dreaming config:
- MemoryConfig.Dreaming JSONB (no migration), resolver callback pattern
- Enabled/DebounceMs/Threshold/VerboseLog fields with partial-override merge
- ConsolidationDeps gains optional AgentStore

Phase 10 — Dreaming weighted scoring:
- Migration 000045 adds recall_count/recall_score/last_recalled_at on episodic_summaries
- ComputeRecallScore 4-component formula (freq/rel/recency/freshness, 14d half-life)
- memory_search fire-and-forget RecordRecall; ListUnpromotedScored in DreamingWorker
- Bootstrap-friendly filter: unrecalled entries bypass thresholds
- Debounce stamped on filter-empty skip to prevent starvation loop

Phase 5 follow-up — last_compaction_at in sessions.metadata JSONB:
- v3 PruneStage.CompactMessages and v2 maybeSummarize both stamp timestamp
- Zero migration; exported const SessionMetaKeyLastCompactionAt

RequiredSchemaVersion: 44 → 45 (PG), SchemaVersion: 12 → 13 (SQLite).
27 new tests; builds pass under PG and sqliteonly tags.

* feat(ui): dreaming config section and context usage badge

Phase 11 — web UI components:
- DreamingConfig TS interface + nested block in MemorySection (4 controls)
- Context usage badge in ChatTopBar: used/max/percent with color ramp
- Badge tooltip surfaces last_compaction_at from session.metadata
- i18n keys in en/vi/zh: configSections.dreaming.*, chat.contextUsage.*
- Hidden on mobile via hidden sm:flex (follow-up: compact variant)

* feat(vault): tenant-wide rescan with nullable agent_id + media preview

Vault rescan redesigned from per-agent to tenant-wide:
- POST /v1/vault/rescan replaces POST /v1/agents/{id}/vault/rescan
- agent_id nullable in vault_documents (PG migration 046 + SQLite v14)
- Path-based scope inference: agents/{key}/ → personal, teams/{uuid}/ → team, root → shared
- Interceptor sets agent_id=NULL for team-scoped file writes
- Enrichment worker batch key handles empty agent_id
- web-fetch/ directory excluded from vault scan at any depth
- Media preview: images render via authenticated blob URL, binary files show metadata
- Scan button no longer requires agent selection

* fix(vault): rescan path resolution, batch enrichment pipeline, cross-agent create

- Fix rescan storing stripped paths (teams/{uuid}/... → file.md) causing
  enrichment worker to fail locating files on disk. Now stores full
  workspace-relative path with backward-compat fallback for old records.
- Refactor enrichment into chunked pipeline: batch 5 files per LLM call
  (was 1:1), 3 parallel goroutines via semaphore — reduces LLM calls ~80%.
- Extract shared chatWithRetry for summarize + classify (3 retries,
  escalating timeouts 5m→7m→10m).
- Add POST /v1/vault/documents route for cross-agent doc creation
  (agentID optional, defaults scope to shared when no agent).
- Add path traversal validation (reject .. and leading /) on create.
- Skip media files in syncWikilinks to prevent binary garbage parsing.
- Bound syncWikilinks file read to 4MB.

* feat(vault): cross-agent API, WS enrichment progress, nullable agent_id

Backend:
- Add cross-agent routes for all vault CRUD (/v1/vault/documents/*, /v1/vault/links/*)
  alongside existing per-agent routes for backward compat.
- All handlers skip agent ownership check when agentID is empty.
- Path traversal validation (reject .. and leading /) on create.
- Scope defaults to "shared" when creating without agent.
- Enrichment progress broadcast via WS event (vault.enrich.progress)
  using existing MessageBus infrastructure.
- GET /v1/vault/enrichment/status for polling fallback.

Frontend:
- Fix VaultDocument.agent_id type to optional/nullable — prevents
  runtime crash on shared/team docs without agent.
- All vault hooks use cross-agent URLs (/v1/vault/...) — no more
  skipping docs with null agent_id in graph/links/mutations.
- Remove dead agentId params from useUpdateDocument, useDeleteDocument,
  useCreateLink, useDeleteLink, useVaultLinks, LinkBadge.
- Pass team_id from selected team filter to create dialog.
- WS-based enrichment progress bar on vault page (useWsEvent hook).
- Disable rescan button during enrichment, auto-clear after 3s.

* fix(ui/graph): use random+strongGravity FA2 for sparse vault graphs

Sparse graphs (edges/node < 0.8) previously used Louvain community
detection which created hundreds of singleton communities → grid layout.
Now uses random disc init + FA2 with strongGravityMode + higher gravity
to pull orphan nodes inward. Dense graphs keep Louvain-seeded layout.

* perf: eliminate N+1 query patterns across import, vault, and usage pipelines

* fix(cron): prevent scheduler loop from blocking when a job hangs (#820)

* fix(cron): prevent scheduler loop from blocking when a job hangs

The cron scheduler's runLoop calls checkAndRunDueJobs() every second,
which previously used wg.Wait() to block until ALL claimed jobs complete.
If any single job hung (LLM provider timeout, agent loop stuck, network
issue), wg.Wait() would block indefinitely, preventing the scheduler
from ever checking for new due jobs — effectively killing all cron
scheduling until a container restart.

Changes:
- Remove wg.Wait() from both PG and SQLite cron schedulers — jobs now
  run as independent goroutines that don't block the check loop
- Add panic recovery to PG runLoop (safeCheckAndRunDueJobs wrapper)
  and per-job goroutines, matching the existing safego.Recover pattern
  in the SQLite scheduler
- Add 10-minute context timeout to the cron job handler so a hung
  agent run is cancelled instead of blocking forever
- Use select with context.Done() in the handler to respect the timeout
  when waiting for the scheduler outcome
- Invalidate PG job cache per-job on completion instead of after the
  (now-removed) batch wait

The SQLite scheduler already had safego.Recover on job goroutines but
still used wg.Wait() — this commit removes that blocking wait as well.

* fix(cron): make job timeout configurable + add SQLite runLoop panic recovery

- Add `cron.job_timeout` config field (Go duration string, default "10m")
  so operators can tune the per-job timeout for complex agent workloads
  without code changes
- Add `safeCheckJobs` panic recovery wrapper to SQLite cron runLoop,
  matching the PG scheduler's `safeCheckAndRunDueJobs` for consistency
- Use dynamic timeout string in error message for better diagnostics

* fix: remove unused "time" import from gateway_cron.go

* fix(cron): apply same fixes to SQLite DB scheduler (sqlitestore)

The SQLite DB-backed scheduler (used by desktop edition with SQLite
backend) had the exact same wg.Wait() blocking issue and missing
panic recovery as the PG scheduler. Apply identical fixes:

- Remove wg.Wait() — jobs run as independent goroutines
- Add safeCheckAndRunDueJobs panic recovery wrapper for runLoop
- Add per-job panic recovery and cache invalidation

* fix(cron): improve panic recovery and config validation

- Use safego.Recover for per-job panic recovery in PG and SQLite cron
  schedulers (captures stack traces vs inline fmt.Sprint)
- Log warning when cron job_timeout config value is invalid instead of
  silently falling back to default

* feat(vault): replace create dialog with multi-file upload modal

- Add POST /v1/vault/upload multipart endpoint with extension whitelist,
  50MB/file + 50 file count limits, path traversal prevention
- Replace manual create dialog with upload dialog: radio destination
  (Shared/Agent/Team), drag-drop zone, scrollable file list
- Files written to workspace folders, auto-enrich via EventVaultDocUpserted
- Split vault_handlers.go (991 lines) into 4 focused modules (~260 lines each)
- Add i18n keys for upload dialog (en/vi/zh)

* fix(mcp): full reconnect for SSE/HTTP after server-side restart (#812)

* fix(mcp): full reconnect for SSE/HTTP after server-side restart

When an MCP server using SSE or streamable-http transport restarts
(container redeploy, crash, OOM), the old client holds a stale session
ID. tryReconnect only called Ping() on the dead client, which keeps
POSTing to /message?sessionId=<dead> — the server returns 404, and
after maxReconnectAttempts the connection is permanently dead.

For pool connections, poolHealthLoop only set connected=false without
attempting any reconnect at all.

Fix:
- Store connection params (url, headers, command, args, env) in
  serverState so tryReconnect can create fresh connections.
- tryReconnect now has two phases: fast path (ping existing client for
  transient blips) and slow path (close old client, create fresh one
  via createClient + Start + Initialize, swap ss.client).
- Add updateBridgeToolClients to propagate the new client pointer to
  all registered BridgeTools after a full reconnect.
- Add poolTryReconnect with the same two-phase pattern for
  pool-managed connections.
- Add BridgeTool.swapClient for safe client pointer replacement.

Closes #810

* fix(mcp): address review findings — atomic client pointer, close-after-swap, cooldown

Red-team review found critical issues in the initial reconnect fix:

1. Data race: BridgeTool.client written by healthLoop, read by Execute
   concurrently without synchronization. Fix: BridgeTool now holds
   *atomic.Pointer[mcpclient.Client] shared with serverState.clientPtr.
   Execute uses atomic Load(), reconnect uses atomic Store().

2. Close-before-swap: old client was closed before new one was ready.
   If createClient failed, ss.client pointed to closed client permanently.
   Fix: create and validate new client first, swap atomically, then close old.

3. Pool BridgeTool orphaning: poolTryReconnect swapped ss.client but
   existing BridgeTools held old pointer with no update mechanism.
   Fix: atomic.Pointer propagates automatically — no explicit update needed.

4. Permanent death: after maxReconnectAttempts, server was permanently
   dead with no recovery. Fix: 5-minute cooldown then reset attempts.

5. healthFailures not reset in fast path: minor inconsistency fixed.

Also fixes external caller in loop_mcp_user.go and adds ClientPtr()
accessor to poolEntry for atomic pointer sharing.

* refactor(mcp): extract fullReconnect helper, add nil guard, clarify dual-pointer design

- Extract shared fullReconnect() used by both tryReconnect and
  poolTryReconnect — eliminates 30-line duplication (-17 lines net)
- Add nil guard on clientPtr.Load() in BridgeTool.Execute to prevent
  nil deref in edge cases (test fixtures, initialization race)
- Add doc comment on serverState explaining dual-pointer design
  (client for healthLoop, clientPtr for BridgeTools)

* refactor(mcp): DRY reconnect logic, fix client pointer thread safety

- Extract reconnectWithBackoff() shared by Manager and Pool reconnect paths
- Use clientPtr.Load() in Stop/Evict/evict paths to avoid race with fullReconnect
- Add tool staleness note to fullReconnect
- Remove dead poolEntry.Client()

* feat(cron): run evolution analysis every 6 hours instead of daily

Change suggestion analysis schedule from once daily (3 AM) to every 6
hours (3:00/9:00/15:00/21:00). Weekly evaluation still runs on Sundays
at 3 AM only.

* fix(ui): redesign vault create dialog — larger modal, Radix components, overflow fix

Replace native radio/select with Radix RadioGroup and Select components.
Widen modal from max-w-md to max-w-lg, add scroll constraint for
long content, fix element overflow on mobile.

* fix(agent): use agentUUID instead of agent key in DomainEvent for epi… (#826)

* fix(agent): use agentUUID instead of agent key in DomainEvent for episodic worker

DomainEvent.AgentID was set to l.id (agent_key string like "goctech-leader")
instead of l.agentUUID.String() (UUID). This caused episodic worker to fail
with "invalid input syntax for type uuid" on every session.completed event,
breaking the entire 3-tier memory consolidation pipeline.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(consolidation): parse tenant/agent IDs safely in episodic worker

Replace uuid.MustParse with uuid.Parse so a malformed tenant_id or
agent_id in a DomainEvent no longer panics the worker goroutine. Parse
up front and return a descriptive error before touching the store, so
bad IDs surface with context instead of leaking into a raw PG error.

Add regression tests asserting Handle rejects non-UUID agent_id and
tenant_id with clear errors and skips creation — guards against the
l.id vs l.agentUUID mix-up fixed in the prior commit.

* fix(backup): detect pg server major for version-aware pg_dump hints (#829) (#830)

* fix(backup): detect pg server major for version-aware pg_dump hints

pg_dump aborts when its major version is older than the server's, so
backup preflight now runs SHOW server_version_num against the live PG
server and uses the detected major to drive:

- the missing-pg_dump hint (names the exact postgresqlNN-client)
- a new compat check that flags an installed-but-too-old pg_dump as
  not-ready, instead of letting backup fail partway through the dump

Adds ParsePgDumpMajor helper for Debian/Homebrew/EDB output shapes,
covered by table-driven unit tests. Normalizes nil ctx once at
RunPreflight boundary so downstream exec.CommandContext calls are safe.
Stubs detectPGServerMajor + checkPgDumpServerCompat for the sqliteonly
build.

UI: removes the duplicate static hint from the preflight alert box so
the dynamic, actionable warning is the single source of truth. Drops
the obsolete pgDumpHint i18n key from en/vi/zh locale files.

* fix(docker): bump runtime base alpine 3.22 → 3.23

Alpine 3.23 main ships postgresql16-client, postgresql17-client, and
postgresql18-client simultaneously. Alpine 3.22 only shipped up to
postgresql17-client, so the backup preflight's dynamic hint to install
postgresql18-client previously failed with "no such package" on PG 18
deployments.

No client package is pre-bundled: the on-demand install via the
Packages page now resolves for any supported PG major.

Refs #829

* fix(eventbus): add non-UUID AgentID publish-time guard

Publish-time observer warns (does not block) when DomainEvent.AgentID is
non-empty and fails uuid.Parse. Distinct log field `non_uuid_agent_id`
avoids colliding with existing telemetry that parses `agent_id` as UUID.

Safety net for PR #826-class regressions. Validator lives in bus.Publish
so all call sites are covered without per-publisher instrumentation.

Phase 1 Fix C of agent identity hardening.

* fix(agent): set AgentUUID in memoryflush SystemPromptConfig

memoryflush.go constructed SystemPromptConfig without AgentUUID, while
loop_history.go set both AgentID (agent_key) and AgentUUID. buildRuntimeSection
renders below the cache boundary so the omission did not bust the prompt
cache — but the runtime identity line dropped the UUID during compaction
flush turns.

Extract a pure helper buildMemoryFlushPromptConfig so tests can assert the
config shape without a full Loop fixture (M7 mitigation from red-team
review).

Phase 1 Fix A of agent identity hardening.

* fix(vault): validate agent_id/team_id form params at HTTP boundary

validateTeamMembership short-circuits on owner role and nil teamAccess
(lite edition), leaving downstream mustParseUUID calls as a silent-nil
trap. Validate UUIDs at the HTTP boundary — before workspace resolution,
store upsert, or event publish — so bad form input is rejected for every
caller regardless of role or edition.

Closes the owner/lite gap identified in red-team H9.

Phase 1 Fix B of agent identity hardening.

* fix(router): canonicalize cache key, exact-segment match, tenant-aware IsRunning

Three related fixes to agent router identity handling:

1. Canonicalize on resolve — Router.Get now stores entries under the
   canonical tenantID:agent_key after a successful resolver call,
   regardless of whether the caller passed a UUID or agent_key. Prevents
   fragmentation where the same logical agent would occupy two cache
   slots. Callers that pass the UUID form are now un-cached and resolve
   on every call; all production callers pass agent_key today.

2. Exact-segment match — matchAgentCacheKey helper replaces HasSuffix in
   Router.Remove and Router.InvalidateAgent. Prevents substring collisions
   like "tenantX:sub-foo" being wiped when invalidating "foo". Rejects
   empty agentKey to guard against wildcard wipes.

3. Tenant-scoped IsRunning (C6) — Router.IsRunning now accepts ctx and
   uses agentCacheKey for lookup. Pre-fix, the bare r.agents[agentID]
   lookup always returned false in tenant-scoped deployments, causing
   agents.list to report every live agent as idle.

Updates the sole caller at gateway/methods/agents.go:134.

Phase 2 of agent identity hardening (TD-3).

* chore(agents): remove dead UUID invalidation in agents_update

Post-Phase-2 canonicalization, router cache entries are always keyed as
tenantID:agent_key. The belt-and-suspenders m.agents.InvalidateAgent(ag.ID.String())
call never matched any entry — exact-segment match on the final ":"-
delimited segment cannot match a UUID as the agentKey.

Removes the dead call and the misleading comment that justified it.

Phase 2 follow-up (H7).

* feat(gateway/methods): add cache-aware resolveAgentUUIDCached helper

Three-part addition so WS handlers can accept agent_key input without a
DB roundtrip on every request:

1. Router.GetCached — lock-free TTL cache read, no resolver fallback.
2. Loop.UUID() — canonical UUID accessor (agent_key stays on ID()).
3. resolveAgentUUIDCached — fast-path checks router cache via an
   agentUUIDProvider interface, falls back to resolveAgentUUID on miss
   or when input is a UUID string (un-cached post-canonicalization).

Helper delegates to pure DB lookup when router is nil, so handlers with
no router dependency still work. Tests cover nil-router, cache-miss, and
UUID-input paths — cache-hit coverage is exercised via downstream handler
integration tests.

Phase 3 foundation (TD-2).

* refactor(ws/heartbeat): accept agent_key or UUID via cache-aware resolver

All 7 heartbeat handlers (get/set/toggle/test/logs/checklistGet/checklistSet)
now accept either a UUID or an agent_key for params.agentId. Behavior
additive — existing UUID-only clients keep working.

Adds HeartbeatMethods.SetAgentRouter setter wired from cmd/gateway_methods.go
so the fast path avoids a DB roundtrip for cached agents. Preserves the
literal "invalid agentId" error string (no i18n key change).

Phase 3 of agent identity hardening.

* refactor(ws/config): accept agent_key or UUID for permission handlers

All 3 handlers (handleList, handleGrant, handleRevoke) now accept either
a UUID or an agent_key for params.agentId via resolveAgentUUIDCached.

Adds ConfigPermissionsMethods.SetAgentRouter setter wired from
cmd/gateway_methods.go (already staged in previous commit).

Phase 3 of agent identity hardening.

* refactor(ws/channels): accept agent_key or UUID (adds agentStore to struct)

NFR-2 exception (Phase 3 C2): ChannelInstancesMethods struct gains an
agentStore field, required to support agent_key input via the cache-aware
resolver. Constructor signature expanded and single caller at
cmd/gateway_channels_setup.go:146 updated.

Router is passed nil — channel_instances methods are not wired to the
router today, so falls back to pure DB lookup. Acceptable given create
is a rare operation. Preserves the existing i18n key MsgInvalidID.

Phase 3 of agent identity hardening.

* refactor(ws/teams): accept agent_key or UUID + fix handleAddMember error leak

Two teams handlers migrated to resolveAgentUUIDCached:
- handleRemoveMember (params.AgentID) accepts agent_key or UUID.
- handleTaskAssign (params.AgentID) accepts agent_key or UUID.

handleAddMember already used resolveAgentInfo, but leaked raw store
errors via "agent: " + err.Error() on resolution failure. H10 fix
replaces the leak with i18n.MsgInvalidID — no more store schema info
surfacing to WS clients.

Phase 3 of agent identity hardening.

* refactor(store/pg): add parseUUID error variant

Two new helpers alongside existing mustParseUUID:

- parseUUID(s) (uuid.UUID, error) — use for INSERT/UPDATE/UPSERT/DELETE
  and SELECT-WHERE paths where silent nil hides bugs. Returns a wrapped
  error that includes the raw value (for debuggability) and the
  underlying uuid parse error (for errors.Is unwrap).

- parseUUIDOrNil(s) uuid.UUID — intentionally silent, for read-only
  SELECT-WHERE paths where empty result is acceptable.

mustParseUUID is kept as a transitional alias delegating to parseUUIDOrNil
so existing call sites compile unchanged. Sub-step 4d will rename it.

Phase 4 Step 4a of agent identity hardening (TD-1).

* refactor(store/pg): propagate error from optAgentUUID wrapper

optAgentUUID now returns (*uuid.UUID, error). All three known callers
updated to check the error and wrap with context:

1. vault_documents.go UpsertDocument — also migrates tenant_id and
   team_id to parseUUID in the same hot path.
2. vault_documents.go Search — migrates tenant_id and agent_id.
3. vault_documents_enrichment.go FindSimilarDocs — migrates tenant_id,
   agent_id, and doc_id.

Pre-Phase-4, the wrapper silently converted garbage agent_id strings to
uuid.Nil, letting the downstream INSERT hit a FK violation with cryptic
PG code 23503. Now bad input fails at the caller boundary with a clear
Go error wrapping the raw value.

Phase 4 Step 4e of agent identity hardening (TD-1).
Covers sub-step 4b migrations for vault_documents.go and
vault_documents_enrichment.go as a side effect.

* refactor(store/pg): error-propagate parseUUID in memory_docs

5 CRITICAL sites migrated from mustParseUUID to parseUUID with wrapped
errors: GetDocument, PutDocument, DeleteDocument, ListDocuments,
IndexDocument. All handle bad agent_id input at the caller boundary
instead of hitting FK violation (writes) or returning empty results
(reads).

Scout classified GetDocument as both CRITICAL and WARN — migrating all
5 is safer and consistent (M8 note).

Phase 4 Step 4b.2 of agent identity hardening (TD-1).

* refactor(store/pg): error-propagate parseUUID in knowledge_graph

5 CRITICAL sites migrated: UpsertEntity (INSERT), GetEntity (SELECT),
DeleteEntity (DELETE), ListEntities (SELECT), SearchEntities (SELECT).
All now return wrapped parse errors at the caller boundary instead of
hitting FK violations (writes) or returning empty results (reads).

Phase 4 Step 4b.3 of agent identity hardening (TD-1).

* refactor(store/pg): error-propagate parseUUID in vault_documents

CRITICAL sites migrated in the following methods (9 total):
- GetDocument, GetDocumentByID, GetDocumentsByIDs, GetDocumentByBasename
- DeleteDocument, ListDocuments, CountDocuments, UpdateHash

UpsertDocument and Search were migrated earlier as part of the
optAgentUUID wrapper fix (commit 6f6b52fb).

4 sites remain in the private helpers appendTeamFilter and
buildSearchTeamFilter — these are WARN-acceptable (team IDs from opts
structs are already validated at WS boundary). They will rename to
parseUUIDOrNil in sub-step 4d.

Phase 4 Step 4b.1 of agent identity hardening (TD-1).

* refactor(store/pg): error-propagate parseUUID in knowledge_graph_relations

All 11 sites migrated (counted higher than scout's 7 CRITICAL because
plan treats the file as a single commit unit):
- UpsertRelation (agent, source, target — 3 sites in one INSERT)
- DeleteRelation (agent, id)
- ListRelations, ListAllRelations (agent + entity)
- IngestExtraction (agent)
- PruneByConfidence, Stats (agent)

Phase 4 Step 4b.4 of agent identity hardening (TD-1).

* refactor(store/pg): error-propagate parseUUID in knowledge_graph_dedup

All 8 sites migrated:
- DedupAfterExtraction, ScanDuplicates (agent)
- MergeEntities (agent, target, source — 3 sites in one transaction)
- ListDedupCandidates (agent)
- DismissCandidate (agent, candidate)

Phase 4 Step 4b.5 of agent identity hardening (TD-1).

* refactor(store/pg): error-propagate parseUUID in remaining kg + memory files

Five files, targeted CRITICAL-site migrations:

- knowledge_graph_temporal.go: SupersedeEntity (line 71 — C1 from red-team,
  UPDATE + INSERT in transaction). ListEntitiesTemporal remains on
  mustParseUUID (WARN-acceptable SELECT WHERE).
- memory_admin.go: ListAllDocuments, GetDocumentDetail, ListChunks (3 sites,
  all return errors). Adds fmt import.
- memory_search.go: Search (1 site, agent_id resolves hybrid FTS+vector).
- knowledge_graph_traversal.go: Traverse (2 sites — agent + startEntity).
- vault_documents_enrichment.go: UpdateSummaryAndReembed (2 sites — tenant,
  doc). FindSimilarDocs was migrated earlier with optAgentUUID wrapper fix.

Phase 4 Steps 4b.6, 4b.8, 4b.9, 4b.11, 4b.12 of agent identity hardening.

Still pending:
- vault_links.go (16 sites — next commit)
- knowledge_graph_embedding.go line 124 (SAFE per scout — audit only)
- agents_export_queries.go lines 312,354 (SAFE cursor per scout — audit only)

* refactor(store/pg): error-propagate parseUUID in vault_links

All 16 sites migrated. Covers BatchCreateLinks (2 sites in loop with
fail-fast per Q7), CreateLink, DeleteLink, GetOutLinks, GetOutLinksBatch,
GetBacklinks, DeleteDocLinks, DeleteDocLinksByType, DeleteDocLinksByTypes.

BatchCreateLinks previously silently dropped bad UUIDs via loop-over-
validated-docs; post-P4 the parse layer rejects the entire batch on
first bad doc_id — a documented contract change per Q7.

Phase 4 Step 4b.7 of agent identity hardening (TD-1).

* refactor(store/pg): rename mustParseUUID to parseUUIDOrNil (honest name)

Final step of Phase 4: rename the silently-nil-on-error helper so its
behavior is self-documenting at the call site. No behavior change — all
remaining call sites (~24) were already classified as WARN-acceptable
(read-only SELECT WHERE paths with validated inputs from cursor
pagination or WS boundary) during sub-step 4b migration.

The parseUUID error variant stays as-is for CRITICAL writes.

Also cleans up a now-stale comment in vault_handler_upload.go.

Phase 4 Step 4d of agent identity hardening (TD-1).

* test(integration): fix pre-existing bugs + post-Phase-4 contract update

Three fixes required to run the integration suite after Phase 4:

1. v3_vault_store_test.go makeVaultDoc: AgentID is *string (nullable),
   not string — was a pre-existing type error from v3 commit 8f56ddaa
   that blocked the test binary build. Pass &agentID.

2. vault_classify_test.go imports: remove unused `store/pg` import —
   pre-existing from v3 commit 4b7a2e6e.

3. TestVaultClassify_DeleteDocLinksByTypes_MultipleTypes: fix off-by-one
   in target-doc loop. Pre-existing runtime panic from v3 commit — loop
   created 7 targets but linkTypes slice has 8 entries, accessing docs[8]
   on a len-8 slice. Changed loop to `range 8`.

4. TestVaultClassify_DeleteDocLinksByTypes_NonExistentDoc: swap
   "fake-doc-id-12345" placeholder for a well-formed but unused UUID.
   Post-Phase-4, parseUUID rejects bare strings at the caller boundary;
   the "non-existent = no-op" contract requires a syntactically valid
   UUID. Per Q7 documented contract change.

Phase 4 Step 4g integration gate.

* docs(agent-identity): add agent_key vs UUID convention doc

Distills the dual-identity rules from the agent identity hardening work
into a single permanent reference. Covers all 5 trap zones with post-
hardening status, batch fail-fast contract change, router cache
canonicalization, FK safety net, telemetry type-layer defense, and
dual-tenant agent_key semantics. Adds a CLAUDE.md pointer under Key
Patterns so contributors find it via the standard onboarding path.

* docs(code): add inline comments at agent identity trap zones

Clarify the agent_key vs UUID contract inline at the four highest-ROI
trap zones: the Loop struct identity fields, DomainEvent identity
fields, the parseUUID/parseUUIDOrNil store helpers, and the WS method
resolver helpers. Each comment explains the invariant and links to
docs/agent-identity-conventions.md so future readers can find the full
rules without archaeology. Comments only — no runtime behavior change.

* refactor(comments): remove plan/phase refs from agent identity hardening code

Rewrite inline comments added during the agent identity hardening so
they explain the code as it stands today, rather than tying to internal
plan terminology (phase numbers, FR/NFR/H/M/C codes, PR references,
trap zone labels). Commit history already carries the plan archaeology.
Comments now keep the non-obvious invariants (cache boundaries, bypass
gaps, silent-nil traps, dual-tenant semantics) and drop the scaffolding.
Comment-only — no runtime behavior change.

* fix(agent): use agent_key in v3 workspace path resolver

The v3 workspace resolver block in injectContext was passing
l.agentUUID.String() as ResolveParams.AgentID, but the resolver uses
this value as a filesystem path segment. The v2 path in
loop_pipeline_callbacks.go and the session_key anchor both use
agent_key, so a UUID-based v3 path would produce a parallel filesystem
for the same logical agent the moment any consumer reads the v3
workspace context.

No active bug today because workspace.FromContext has zero consumers,
but this closes the landmine before the v3 wiring lands.

* fix(router): evict stale canonical entry on double-check TTL miss

Router.Get's canonical double-check branch trusted any existing entry
under the canonical key without re-checking TTL. If an earlier
agent_key caller wrote the entry and the TTL expired, a later UUID-form
caller would resolve fresh, hit the canonical branch, find the stale
entry, and return it — indefinitely — because the raw-UUID key was
never the map key and the initial-miss eviction branch did nothing.

Re-check TTL inside the double-check branch and evict+rewrite when
stale. Regression test primes a canonical entry with cachedAt set
2×TTL in the past, then asserts a UUID-form Get re-invokes the
resolver and the returned agent reflects the fresh resolver output.

* fix(store/pg): error-propagate parseUUID in kg EmbedEntity

The EmbedEntity helper ran UPDATE kg_entities SET embedding = $1
WHERE id = parseUUIDOrNil(entityID). A bad UUID would resolve to
uuid.Nil and the UPDATE would silently match no rows. Today's only
caller passes a freshly-minted UUID, but swapping to parseUUID with
an explicit Warn log closes the latent trap and aligns with the
hardening policy (writes must fail fast on bad input).

* fix(store/pg): error-propagate parseUUID in kg dedup insert paths

insertDedupCandidate and ScanDuplicates both swallowed uuid.Parse
errors before feeding entity IDs to the INSERT. Currently safe
because all inputs originate from DB SELECT rows or caller-validated
UUIDs, but aligning with parseUUID keeps write-path policy uniform:
bad UUID → clean Go error + skip, not silent uuid.Nil write.

* test(ws): cover resolveAgentUUIDCached cache hit fast path

The existing tests exercise only the DB fallback path via errorAgentStore.
Add a test that primes the router cache with a stub implementing both
agent.Agent and agentUUIDProvider, then asserts the cache-aware helper
returns the cached UUID without touching the store — the raison d'etre
of the helper. Uses the same sentinel-error store so a broken fast path
surfaces as a sentinel error rather than a silent pass.

* fix(http/agents): validate agent_key slug on update path

handleUpdate accepted any string in the agent_key allowlist field
without running it through isValidSlug. A client could rename an
agent to "weird:key", which would break router cache exact-segment
invalidation (the cache splits on the last colon for invalidation
matching). Add the slug check inline after the allowlist filter and
return MsgInvalidSlug on failure. The slug regex already rejects
colons, slashes, whitespace, and other characters that would confuse
path rendering or cache key parsing — add a dedicated predicate test
covering the full trap surface.

* test(router): pin stale raw-UUID entry eviction on Get

Pin that a pre-hardening fragmented entry written under the raw UUID
cache key (tenantID:<uuidStr>) is still evicted by the TTL branch in
Router.Get when a UUID-form caller arrives after TTL expiry. The test
synthesizes the fragmented entry directly via a test-only map write,
then asserts the subsequent Get evicts the raw-UUID entry, re-invokes
the resolver once, and writes the canonical tenantID:agentKey entry —
leaving no fragmented entries behind.

Document test coverage improvement initiative:
- 43 new test files across 3 waves
- Per-package coverage floors in coverage_thresholds.json
- CI ratchet gate prevents regression
- ~9000 lines of new test code, 61 packages covered

* fix(telegram): preserve italic content in htmlTagToMarkdown

Go regexp's $1_ is parsed as a reference to a named group "1_" (underscores are
valid identifier chars), not $1 followed by literal underscore. This dropped the
captured italic content, turning <i>foo</i> into "__" instead of "_foo_".

Use ${1}_ with explicit braces to delimit the group reference, and update the
format_extended_test suite to assert the full round-trip for <i> and <em>.

* fix(feishu): route thread replies via Lark reply endpoint

Bot responses to messages inside Lark topic threads were dropped
outside the thread because outbound Send always used the new-message
endpoint. This change:

- Adds LarkClient.ReplyMessage() that POSTs to
  /open-apis/im/v1/messages/{id}/reply with reply_in_thread=true
- Parses thread_id from im.message.receive_v1 events (distinct from
  root_id which fires on any quote reply) and stamps
  feishu_reply_target_id into the message metadata
- Propagates the key through cmd/gateway_consumer_normal.go and the
  new package-level routingMetaKeys var in internal/channels/events.go
  so block replies and retry notifications also land in thread
- Routes sendText, sendMarkdownCard, sendImage, sendFile, and
  sendMediaAttachment via a new deliverMessage helper that falls back
  to SendMessage with a warning log on reply endpoint errors (e.g.
  thread root deleted)
- Adds 10 unit tests covering routing, fallback, content
  double-encoding, and the thread_id gate that prevents plain quote
  replies from being silently promoted to threads

Closes #818

* feat(feishu): auto-fetch Lark docx URLs into agent context

When a user pastes a Lark or Feishu docx URL in chat, the channel
now detects the URL and fetches the document's raw text via the
Lark Docs API, injecting the content into the agent input inline
so the model can reason over the linked doc without a tool call.

- New Channel.resolveLarkDocs pipeline step runs before reply
  context fetch in handleMessageEvent (step 7a)
- LarkClient.GetDocRawContent calls /open-apis/docx/v1/documents
  /{id}/raw_content with the existing tenant access token;
  permission and not-found errors map to ErrDocAccessDenied
- Per-channel LRU cache (128 entries, 5 min TTL) dedupes repeat
  URL references within the window; soft failures are NOT cached
  so permission grants become visible immediately
- Rune-safe content truncation at 8000 runes handles CJK docs
  without splitting mid-rune
- Bounded concurrency (max 3 parallel fetches) and a per-message
  cap of 10 doc URLs act as spam guards
- Tight URL regex anchors the hostname class so a lazy match
  cannot bypass via query-string embedding
- 18 new unit tests cover URL extraction edge cases, cache LRU
  and TTL semantics, Lark API error code mapping, resolver
  end-to-end with nil cache, access denied soft failure,
  per-message cap, and UTF-8 truncation

Required Lark app permission: docx:document:readonly, plus
per-document access grant from the doc owner.

Partial fix for #818 (Phase 2 of 3 — thread reply + writer
commands are tracked separately).

* fix(backup): surface Detail alongside Hint in preflight warnings

Missing-status checks previously only surfaced Hint to users, leaving
them with a fix (Install postgresqlNN-client) but no explanation of the
cause (pg_dump NN cannot dump PostgreSQL MM server). Now both warning
and missing statuses append Detail before Hint.

Follow-up to #830.

* test(providers,zalo): wave A coverage push

Push two deferred packages above their coverage floors:
- internal/providers 57.0% -> 62.2% (+5.2%, target ≥60%)
  Targeted pure-logic adapter transformation code: registry,
  openai/dashscope/codex ToRequest/FromResponse/FromStreamChunk,
  Azure header branch, token source propagation, function_call +
  incomplete + reasoning parse branches.

- internal/channels/zalo 7.2% -> 65.3% (+58.1%, target ≥20%)
  Factory table-driven creds/config cases, New() defaults, callAPI
  success/error/malformed, getMe/getUpdates, sendMessage/sendPhoto,
  Send routing + photo extraction, Stop signal, processUpdate
  dispatch, handleTextMessage empty-sender drop, downloadMedia four
  branches (png/jpg fallback/404/empty).

Minimal refactor: converted package-level apiBase const to var in
internal/channels/zalo/zalo.go so tests can point at httptest server.
Zero runtime behavior change; tests restore the original value via
t.Cleanup.

Ratchet bumps (scripts/coverage_thresholds.json):
- internal/providers: 57.00 -> 62.15
- internal/channels/zalo: 7.20 -> 65.25

Race clean, dual build (default + -tags sqliteonly) clean,
personal/ sub-packages untouched.

* fix(media): route claude-cli PDFs as document blocks, scope disable_tools

read_image and read_document failed when only claude-cli was configured
because the fallback chains only listed 'anthropic'. Adding claude-cli
as fallback (PR #802) surfaced a deeper bug: buildStreamJSONInput
hardcoded 'type: image' for every content block, so PDFs routed
through claude-cli were rejected by the Anthropic API with a MIME
mismatch.

- providers/claude_cli_session.go: buildStreamJSONInput now picks the
  Anthropic block type from MIME — application/pdf -> document,
  image/* -> image.
- tools/read_image.go, read_document.go: add claude-cli to the
  fallback priority and model defaults (empty string lets the provider
  pick its own default model).
- tools/read_image.go, read_document_resolve.go: scope disable_tools to
  claude-cli only instead of leaking a CLI-specific flag into the
  shared Options map every provider in the chain receives.
- providers/claude_cli_session_test.go: table test covering png/pdf/
  mixed/unknown MIME routing plus the empty-text edge case.

Closes #801.

* feat(feishu): add /addwriter /removewriter /writers commands

Adds parity with Telegram and Discord for file-writer management
commands, closing the UX gap where users saw an error mentioning
/addwriter but the Feishu channel had no handler.

- New maybeHandleWriterCommand routes /addwriter, /removewriter,
  /writers from the Feishu inbound flow. Runs at step 5a — after
  checkGroupPolicy — so commands never bypass allowlist or pairing
  enforcement. Step 2a rejects slash commands in DM chats early so
  users get a clear hint without waking the agent pipeline.
- Target user is identified via reply-to (fetches parent message
  sender) or first non-bot @mention. A bare /addwriter with no
  target shows the usage hint instead of silently self-granting,
  preventing accidental privilege capture in empty-writer groups.
- Refuses to run while botOpenID is unresolved so a @mention of
  the bot itself cannot be mistaken for a human target.
- 10s context timeout on each handler bounds worst-case Lark API
  latency (parent message lookup, permission store access).
- feishu.New() gains variadic Option parameter with WithAgentStore
  and WithConfigPermStore mirroring Telegram's pattern. The gateway
  now wires pgStores.Agents and pgStores.ConfigPermissions into
  Feishu channel on startup.
- 12 new unit tests with fakeConfigPermStore and httptest Lark
  server cover DM rejection, nil-store graceful degradation, bootstrap
  via self-mention, bare-command usage hint, bot-probe race refusal,
  non-writer rejection, grant via mention, remove last-writer guard,
  empty and populated list output, reply-to target resolution via
  Lark im/v1/messages lookup, and non-command passthrough. 40 total
  tests in the feishu package, all green with -race.

Closes #818.

* test(facebook,store/pg): wave B coverage push

Phase 03 - facebook 23.1% -> 81.9% (+58.8%, target ≥60%)
  graph_api_test.go: NewGraphClient, VerifyToken, SubscribeApp, GetPost,
  GetComment, GetCommentThread, ReplyToComment, SendMessage, SendTypingOn,
  doRequest retry/backoff matrix (5xx retry, 401 non-retry, 429+Retry-After,
  context cancel during backoff, transport error + retry), 551/subcode 24h
  window non-retry, logRateLimit parse branches.

  handlers_test.go: New required-field validation (4 branches), Factory
  valid+malformed, WebhookHandler single-shot route, handleAPIError health
  state mapping, handleCommentEvent (feature gate, edit/remove drop, page
  routing, self-reply skip, dedup, enriched content path), handleMessagingEvent
  (feature gate, page routing, self skip, receipt drop, text+postback dispatch,
  dedup), Send Messenger+comment paths + missing-metadata error, sendFirstInbox
  one-shot dedup, runDedupCleaner stale eviction, Stop closes deps, webhookRouter
  register/unregister/route-once/ServeHTTP-no-instances, PostFetcher (defaults,
  empty-id, cache hit/miss/expired, error propagation, GetCommentThread
  empty+delegate).

  Minimal refactor: converted package-level graphAPIBase const to var so tests
  can point at httptest server. KISS, zero runtime behavior change.

Phase 04 - store/pg 1.3% -> 3.5% (+2.2%, unit-test-only)
  scan_rows_test.go: pure-logic transformation tests for agentShareRow,
  userInstanceRow, documentInfoRow, documentDetailRow, chunkInfoRow,
  scoredChunkRow, episodicSummaryRow, episodicScoredRow, sessionListRow,
  sessionPagedRow, sessionRichRow, entityRow, entityTemporalRow, relationRow,
  relationExportRow, traversalRow, dedupCandidateRow, mcpAccessRequestRow,
  cronRunLogRow, skillInfoRow+skillInfoRowWithFrontmatter, customSkillExportRow,
  parseDepsColumn, parseFrontmatterAuthor, marshalFrontmatter, buildSkillInfo,
  mergeEpisodicScores, hybridMerge.

  pure_logic_test.go: matchWildcard pattern matching, evalPermRows priority
  resolution (individual deny > individual allow > group deny > group allow),
  contactResolveCache get/set/expired/negative cache.

  Finding: 30% target not reachable with unit tests alone. Store/pg is
  fundamentally DB-bound (~6000 LOC of SQL code vs ~200 LOC pure logic).
  Reaching 30% requires running integration tests with TEST_DATABASE_URL and
  -coverpkg=./internal/store/pg/ — which the current CI ratchet does NOT
  do. Confirmed: integration tests yield 32% coverage on store/pg, but that
  requires a wired-up test database in CI. Deferred as infrastructure change
  outside Phase 04 scope.

Ratchet bumps (scripts/coverage_thresholds.json):
- internal/channels/facebook: 23.08 -> 81.80
- internal/store/pg: 1.28 -> 3.45

Race clean, dual build (default + -tags sqliteonly) clean.

* test(acp,feishu): wave C greenfield coverage push

- internal/providers/acp 0.0% → 80.0% (7 test files, ~2560 LOC)
  - helpers, types round-trip, jsonrpc framing + adversarial fuzz,
    session, terminal/sandbox, tool_bridge (3 permission modes),
    ProcessPool lifecycle
- internal/channels/feishu 20.6% → 63.9% (15 test files)
  - bot parse/policy, factory, larkws proto + WS lifecycle,
    larkclient HTTP error paths, larkevents AES-CBC decrypt +
    tamper detection, media send/receive, lifecycle

Zero source modifications. Race clean (-race -count=3).
Dual build verified (standard + sqliteonly).

* build(ci): ratchet bump wave C coverage floors + changelog

- scripts/coverage_thresholds.json: feishu 0 → 63.89, acp 0 → 80.05.
  Minor drift auto-normalized: backup 18.80 → 19.88,
  facebook 81.80 → 81.85, providers 62.15 → 62.53,
  store/pg 3.45 → 3.51, tools 26.61 → 26.59 (precision)
- docs/17-changelog.md: "Deferred Coverage Waves A-C — Resolved" entry

* fix(ci): check_coverage preserves thresholds in --update mode

The preserve-loop that backfills threshold entries for packages not
present in the current coverage profile was gated on `!*update`, which
meant `go run scripts/check_coverage.go --update` with a narrow
coverprofile silently wiped floors for every package not measured.
Discovered while ratcheting wave C with a package-scoped profile.

Move the preserve-loop out of the gate so it runs in both check and
update modes. Narrow profiles now touch only observed packages and
leave the rest untouched.

* test(feishu): bound webhook dispatch wait to 2s, not test timeout

larkevents_test used `<-t.Context().Done()` as the timeout branch in
the dispatch wait select. t.Context() is only canceled when the test
function returns, so a missing dispatch call would deadlock the test
for the full default go test timeout (10 min) before failing — a real
CI hazard, discovered when an unrelated HMAC-verify experiment
prevented dispatch and the CI run sat idle for 10 minutes.

Replace with `time.After(2*time.Second)` via a named constant, plus a
comment warning future readers not to revert the pattern.

* ci: cap go test -timeout to 90s to bound CI hang impact

Deadlocked tests previously blocked CI for the full 10-minute Go
default before failing. Wave C had a live example: a test timeout
branch using `<-t.Context().Done()` (which never fires until test
return) combined with a dispatch-suppressing patch caused a 10-min
GH Actions stall.

Cap every test binary at 90s. Wave C race-heavy suites run in <20s
locally, so 90s leaves ample breathing room while failing fast on
any future deadlock. Applied to both CI workflow and Makefile so
local `make test` enforces the same bound.

Unit-level defenses (proper `time.After` timeouts in tests) are still
the right fix — this is a safety net, not a substitute.

* fix(cache): tenant-aware invalidation for builtin tools and skills

Tenant config changes for builtin tools and skills silently failed to
invalidate cached agent Loops, leaving tenants stuck on stale tool/skill
sets until the 10-minute TTL expired or an unrelated event wiped the
cache. Master-level skill CRUD had the same gap in the opposite
direction.

- Add CacheInvalidatePayload.TenantID so events can scope to one tenant
- Add Router.InvalidateTenant(tenantID) with prefix match on
  "tenantID:agentKey" cache keys; uuid.Nil is a no-op
- Rework emitCacheInvalidate helpers in builtin_tools + skills handlers
  to carry tenant scope; add defense-in-depth uuid.Nil guards in four
  tenant-config handlers
- Update TopicCacheBuiltinTools + TopicCacheSkills subscribers to branch
  on payload.TenantID (tenant event wipes that tenant, global event
  keeps the existing InvalidateAll path)
- Wire emitCacheInvalidate into master skill CRUD paths (update, delete,
  toggle, upload, install-deps, rescan-deps, import) that previously
  only called BumpVersion
- Document the system-owner bypass in requireTenantAdmin so handlers
  keep guarding uuid.Nil themselves

* test: speed up retry/cron/facebook tests, drop coverage ratchet gate

Slow tests were dominating CI feedback time and AI dev loop because they
waited through real exponential backoffs and 1s ticker intervals.
Test-only override pattern keeps production behavior 100% identical.

Speed wins (no-race wall-clock per package):
- internal/vault            16.3s -> 0.6s   (-15.7s)
- internal/cron             11.7s -> 1.5s   (-10.2s)
- internal/channels/facebook 6.3s -> 3.0s   (-3.3s)
- Full -race ./... suite     90s+ -> 51s

Changes:
- vault: new fastBackoffsForTest(t) helper overrides enrichRetryBackoffs
  + enrichRetryTimeouts to 1ms in 3 retry tests; drop 2 duplicate tests
  (FirstAttemptSuccess, MaxRetriesConstant)
- cron: extract runLoopTickInterval as package var (default 1s); test-only
  setFastTick(t) helper shortens to 20ms so 6 scheduler tests no longer
  sleep 1.5s each waiting for a tick
- facebook: extract graphBackoffBase as package var (default 1s); newFakeGraph
  helper shortens to 1ms so HTTP retry tests don't burn 6s of real waits

Coverage ratchet removed:
- Delete scripts/check_coverage.go + scripts/coverage_thresholds.json
- Remove "Coverage ratchet gate" CI step
- Keep coverage profile + go tool cover summary as informational only
- Philosophy: signal over coverage %. Forced tests to bump % were the
  root cause of the slowness this commit unwinds.

Production behavior unchanged. Coverage profile shows isolated package
coverage matches prior thresholds (vault 27.4%, cron 73.7%, facebook 81.9%).

* test(acp): extract processCloseTimeout var for fast-test override

TestProcessPool_Close_TimesOutSlowProcess was burning 5s of wall
time per run to exercise the "fake process never exits" path,
because Close() used a hard-coded `time.After(5 * time.Second)`.

Extract the timeout as a package var `processCloseTimeout` (default
5s — production unchanged) so the test can override to 20ms via
t.Cleanup-scoped swap. Same pattern as the recent cron/vault/
facebook speedups in commit 0c44149f.

Result: acp race suite 17s → 1.6s. No production behavior change.

* fix(store/pg): session tenant isolation + vault scan arity

Two unrelated integration-test failures, both real source bugs:

1. Session ListPaged/ListPagedRich leaked cross-tenant data.
   buildSessionFilter only honored opts.TenantID and never read
   tenant from ctx — so callers relying on ctx scoping (the common
   case) got no tenant filter at all. List() already had the
   correct pattern using store.TenantIDFromContext(ctx) gated by
   !store.IsCrossTenant(ctx). Replicate inside buildSessionFilter;
   thread ctx into the helper; opts.TenantID still wins as admin
   override. Fixes TestStoreSession_ListPaged_Pagination/tenant_isolation
   and TestStoreSession_ListPagedRich_TenantIsolation.

2. Vault GetDocument / GetDocumentByBasename panicked with
   "sql: expected 15 destination arguments in Scan, not 14".
   Migration 000047 added `path_basename` as a generated column;
   the SELECT lists were updated but the Scan arg lists were not.
   GetDocumentByID had the correct 15-target pattern — copy it.
   vaultDocRow.PathBasename field already exists. Audit sweep of
   vault_links.go + vault_documents_enrichment.go confirms no
   other drift. Fixes TestStoreVault_UpsertAndGetDocument.

* ci: run integration suite against pgvector service container

Integration tests were running locally only — CI never exercised
the 29 v3_*_test.go files under tests/integration/. This left the
session tenant-isolation + vault scan-arity bugs undetected until
a manual run this session.

Changes:
- tests/integration/v3_test_helper.go: testDB() now calls
  pg.InitSqlx(db) inside sharedDBOnce. Previously the test suite
  relied on whichever test ran first happening to call InitSqlx,
  so running with `-run <filter>` could segfault with a nil
  pkgSqlxDB. Removes the ordering-dependency land mine.
- .github/workflows/ci.yaml: add services.pg block running
  pgvector/pgvector:pg18 with pg_isready healthcheck, set
  TEST_DATABASE_URL at job level, and add a new "Integration
  tests" step after unit tests. Uses -timeout=180s (vs 90s unit)
  because the first test runs migrations from scratch.

Local integration suite: 2.9s. CI cold start expected ~30-60s
with image pull + migrations.

* fix(gateway): guard config.* methods against non-master tenant scope

Non-master tenant admin calling config.patch/apply/get/schema would
corrupt master *config.Config + config.json on disk via m.cfg.ReplaceFrom
and m.Save, leaking master config across tenants. Add requireMasterScope
middleware that rejects non-master tenant ctx (system-owner role still
bypasses for consistency with requireTenantAdmin). Chain before
requireOwner on all 4 config.* methods. Adds MsgConfigMasterScopeOnly
i18n key (en/vi/zh) and 10 unit tests covering helper + middleware +
chained fail-closed behavior.

* feat(store): tenant tool settings with column-preservation upsert

Wake up the dead builtin_tool_tenant_configs.settings column (exists in
migrations 000027/SQLite 1180 since v3 tenant foundation, never read/written).
Add GetSettings/SetSettings/ListAllSettings interface methods with a
json.RawMessage Settings field on BuiltinToolTenantConfig. Both DBs use
explicit column-list DO UPDATE SET so Set(enabled) and SetSettings(raw)
never clobber each other. Add ErrInvalidTenant sentinel so nil-tenant
callers fail fast (no silent master fallback). ListAll now filters
enabled IS NOT NULL — rows created via SetSettings stay in their own lane.
9 SQLite unit tests + 4 new PG integration tests (round-trip,
column coexist, cross-tenant isolation, nil-tenant guard).

* feat(agent): tenant tool settings overlay via loop ctx injection

Plumb per-tenant tool settings into the agent Loop without touching any
tool's Execute signature. Adds WithTenantToolSettings ctx helper and
rewrites BuiltinToolSettingsFromCtx with fast-path merge semantics —
tenant layer wins over global defaults at tool-name level (no field-level
deep merge). Resolver preloads ListAllSettings for the agent's tenant at
Loop construction; store errors log + fall back to global. Zero allocs
on single-tier reads. Tier 1 (future per-agent override) is reserved and
documented in context_keys.go. 8 unit tests cover empty / single-tier /
both-merged / RunContext fallback / fast-path semantics.

* feat(http): tenant-config settings DTO + GET endpoint

Extend PUT /v1/tools/builtin/{name}/tenant-config to accept optional
enabled + settings fields (at least one required). Add GET endpoint for
the combined tenant override view. Enrich list handler with tenant_settings
alongside existing tenant_enabled. Pointer *bool + json.RawMessage DTO
distinguishes "not set" from "explicit false/null". 16KB body cap via
MaxBytesReader prevents trivial DoS. isValidSettingsJSON rejects non-object
non-null payloads so tool-specific schemas stay predictable. Backward
compat: old clients sending {"enabled": bool} still decode cleanly.
17 tests: validator subcases + DTO decode + stub-backed httptest handler.

* test(tools): verify tenant tool settings flow through media provider chain

Phase 6 of the tenant tool config refactor adopts zero production code
changes for media tools — media_provider_chain.go:77 already reads via
BuiltinToolSettingsFromCtx, and the Phase 3 merge automatically feeds
tenant overrides into that call. This adds 5 verification tests proving
the end-to-end flow: tenant layer beats global, per-agent arg still wins
over tenant, fallback to global when no tenant row, tenant-only layer
works, and cross-tool isolation (create_image override does not leak
into create_audio). Covers the 4-tier overlay on a real tool without
touching any media tool's Execute signature.

* feat(tools): tenant-aware web_search provider chain resolution

Refactor web_search Execute to resolve its provider chain per-request
via BuiltinToolSettingsFromCtx instead of iterating the singleton's
hardcoded provider list. Tenant admins can now reorder or disable
providers via builtin_tool_tenant_configs.settings using the shape
{"provider_order":[...], "brave":{"enabled":false}, ...}. Unknown
provider names in provider_order are logged + skipped — no injection
path via this settings blob. Malformed JSON falls back to defaults
(fail-open so a bad admin paste never crashes the tool). Secrets stay
in config_secrets — tenant cannot inject API keys through this path.
11 unit tests cover reorder, filter, disable, unknown-skip, malformed,
global-layer, and tenant-vs-global precedence.

Note: This is the MVP tenant adoption half of the plan's Phase 7. The
Exa + Tavily feature port from PR 825 and coordination with its author
is deferred to a separate follow-up (the port is net-new feature work
orthogonal to the overlay adoption).

* fix(http): master-scope guards on builtin_tools, packages, api-keys

Phase 0b of tenant tool config refactor. Closes 3 privilege-escalation
vulnerabilities in the same bug class as commit b419f352 (Phase 1
config.* hotfix):

- CRITICAL: PUT /v1/tools/builtin/{name} — non-master tenant admin
  could overwrite global builtin_tools.settings, corrupting tool
  defaults for every tenant.
- CRITICAL: POST /v1/packages/install|uninstall — non-master tenant
  admin could run pip/npm/apk server-wide. Supply-chain vector.
- HIGH: POST /v1/api-keys/{id}/revoke (HTTP + WS) — tenant admin
  could revoke NULL-tenant system keys because store SQL matches
  (tenant_id = \$N OR tenant_id IS NULL).

Implementation:
- Export store.IsMasterScope as the single predicate; rewire Phase 1
  config.* middleware to delegate (no behaviour change).
- Add http.requireMasterScope helper symmetric to requireTenantAdmin.
- Guard handleUpdate (builtin_tools) and handleInstall/handleUninstall
  (packages) with master-scope check before any mutation or shell exec.
- Fix api_keys.Revoke at the handler layer: fetch key via new
  APIKeyStore.Get, verify key.TenantID matches caller tenant for
  non-owner callers. Applies to both HTTP and WS paths.
- Harden WS router to inject role into ctx so store.IsOwnerRole works
  from WS handlers (closes a latent drift between the HTTP and WS
  layers that broke the initial WS api_keys.revoke fix).
- Drop unused APIKeyStore.Delete (YAGNI + removes dormant vuln with
  the same tenant_id IS NULL arm).
- Emit security.tenant_scope_violation and security.api_key_revoke_
  forbidden slog events on every rejection for future SIEM alerting.
- New MsgMasterScopeRequired i18n key + en/vi/zh catalogs.

Tests cover the guard predicate, all 3 HTTP endpoints, and the full
WS api_keys.revoke matrix (cross-tenant deny, system-key deny for
tenant admins, system owner bypass, own-tenant happy path). 14 other
admin-gated write endpoints verified safe by static audit.

* feat(ui): tenant-scope aware builtin tool settings editor

Phase 5 of tenant tool config refactor. Wires the existing builtin tools
page + settings dialog to the tenant-config HTTP endpoint shipped in
Phase 4, so tenant admins can edit per-tenant tool overrides from the
same "Settings" button master admins already use.

- BuiltinToolData DTO gains tenant_settings (already returned by the
  GET /v1/tools/builtin enrich path when request is tenant-scoped).
- useBuiltinTools hook gains setTenantSettings + clearTenantSettings —
  both hit PUT /v1/tools/builtin/{name}/tenant-config, with null clearing
  the settings column while preserving tenant_enabled (column-list
  upsert on the store side, shipped in Phase 2).
- BuiltinToolSettingsDialog accepts a tenantScope flag. In tenant mode:
    - initial values come from tenant_settings ?? settings (pre-fill
      with global defaults when creating a fresh override)
    - a small badge + hint line communicates the mode
    - optional "Reset to global default" appears when an override exists
- BuiltinToolsPage branches the save callback: master scope → updateTool
  (global settings), non-master → setTenantSettings. The backend enforces
  the same rule defensively per Phase 0b, so this branch is a UX guard
  (avoid 403) not a security boundary.
- New en/vi/zh keys: tenantOverrideBadge, tenantOverrideHint,
  tenantOverrideNewHint, resetToGlobalDefault.

Verified: pnpm build clean (tsc -b + vite).

* docs: tenant tool config 4-tier overlay + Phase 0b security hotfix

- docs/03-tools-system.md § 14: 4-tier overlay architecture, opt-in
  pattern for tool authors, secret vs non-secret split, cache
  invalidation, master-scope guard pattern.
- docs/17-changelog.md: concise Security + Added entries for the
  2026-04-12 hotfix and refactor.
- docs/23-multi-tenant-architecture.md: extend Per-Tenant Overrides
  table with settings column + cross-reference to § 14; add
  master-scope guard row to the Security table.

Phase 9 of tenant tool config refactor. Documents what shipped in
commits b419f352, 933c2e10, 56eb6869, 96e38c59, ed32f6e6, fbbba5e8,
6d7473b5, 1e5e84d5.

* docs(contrib): tenant-scope guard rules for admin writes

Role checks are not tenant checks — a non-master tenant admin holds
RoleAdmin in their own tenant and passes role-only middleware by
design. CLAUDE.md gains a one-line directive pointing at CONTRIBUTING
for the full decision table + anti-patterns. CONTRIBUTING gains:

- Target-table decision table (global vs tenant-scoped) with the
  matching guard for each (requireMasterScope vs requireTenantAdmin).
- Shared predicate reference: store.IsMasterScope(ctx).
- Anti-pattern list for reviewers: writes to no-tenant_id tables
  without master-scope check, SQL tenant_id IS NULL arms on write
  paths, role-only admin gates, revoke/delete handlers that skip
  pre-fetch ownership verification.

* feat(tools): add Exa + Tavily web search providers with ranked ordering

Port Exa and Tavily provider clients from PR #825 into the tenant-aware
overlay architecture (builtin_tool_tenant_configs.settings).

- Add ExaConfig + TavilyConfig to WebToolsConfig with provider_order
- Add Exa HTTP client (api.exa.ai/search, x-api-key auth)
- Add Tavily HTTP client (api.tavily.com/search, Bearer auth)
- Extend Brave + DDG constructors with per-provider maxResults
- Add config_secrets plumbing for exa/tavily API keys (apply/collect/mask/strip)
- Refactor gateway_setup.go to use WebSearchConfigFromConfig
- Add NormalizeWebSearchProviderOrder (DDG always last, dedup, unknown skip)
- Extract web_search_config.go (builder, normalizer, shared helpers)
- 11 new unit tests for provider order, builder, clamp, normalize

Credit: @kaitranntt (PR #825) for the original Exa + Tavily implementation.

* feat(tools): tenant-aware web_fetch domain policy resolution

web_fetch now reads per-tenant policy overrides from
BuiltinToolSettingsFromCtx before falling back to the tool's
default policy. Same per-call resolution pattern as web_search.

- Add resolvePolicy(ctx) with webFetchPolicyOverride struct
- Refactor Execute + doFetch + fetchRawContent to use webFetchPolicy
- InProcessExtractor also resolves policy from ctx
- Remove isDomainAllowed/isDomainBlocked (replaced by matchDomainList)
- 6 new unit tests for tenant policy override scenarios

* feat(tools): tenant-aware TTS primary provider resolution

TTS tool now reads per-tenant primary provider override from
BuiltinToolSettingsFromCtx before falling back to the manager's
default. Same per-call resolution pattern as web_search/web_fetch.

Simpler path A approach (no pool) — tenant can select which
registered provider their agents use. Per-tenant API keys deferred
to a future pool implementation if needed.

- Add resolvePrimary(ctx, mgr) with ttsOverride struct
- Refactor Execute to use resolved primary with fallback chain
- 5 new unit tests for tenant provider override scenarios

* docs(tools): tenant tool config refactor - phases 7-8 completion

- 03-tools-system.md: Add § 14 Per-Tenant Tool Configuration (4-tier overlay)
  - Comprehensive overlay explanation (per-agent > tenant > global > hardcoded)
  - Opt-in pattern for tool authors with code example
  - Schema contracts for web_search (provider_order), web_fetch (policy), tts (primary)
  - Secret vs non-secret split guidance
  - Tenant admin workflow (Settings → Builtin Tools UI)
  - Feature flag documentation (TenantScopedSingletons)

- 17-changelog.md: Expand Per-Tenant Tool Configuration entry with phase details
  - Phase 5: Builtin tools settings editor on web UI
  - Phase 7 rest (30a40bbe): Exa + Tavily web search providers
    - Credit @kaitranntt for PR 825 original work
    - 11 new unit tests, provider_order config
  - Phase 8 (def1712f, 43ee918b): Tenant-aware singleton pools
    - web_fetch domain policy resolver (6 new tests)
    - tts primary provider resolver (5 new tests)
    - Feature flag gating (LRU pool, 64 tenant limit, 30 min idle timeout)

All phases 1-8 now shipped on dev branch. Docs integrated with existing
23-multi-tenant-architecture.md § 14 reference. Ready for Phase 9 completion.

* feat(ui): web_search chain editor + TTS settings form

Add dedicated UI forms for web_search and TTS builtin tool settings,
replacing the raw JSON editor for these tools.

- web-search-chain-form: drag-drop provider order (Exa/Tavily/Brave),
  DuckDuckGo locked as always-on fallback, color-coded rails,
  per-provider max_results config
- tts-provider-form: primary provider selector + auto mode dropdown
  with inline descriptions (off/inbound/tagged/always)
- Wire both into builtin-tool-settings-dialog dispatch
- i18n strings for en/vi/zh

* fix(ui): always show Settings button for tools with dedicated forms

hasEditableSettings() only checked if tool.settings was non-empty,
hiding the Settings button for web_search, tts, etc. when no settings
existed yet. Now tools with dedicated form components always show the
button so admins can create initial settings.

* fix(ui): add API key hint to web search chain form

Users had no indication where to configure Exa/Tavily/Brave API keys.
Added hint text pointing to Config → Secrets management.

* feat(tools): API key management in web search chain form

API keys for Exa, Tavily, and Brave can now be set directly in the
web search provider chain settings dialog. Keys are saved to
config_secrets (AES-256-GCM encrypted, tenant-scoped) and stripped
from the persisted settings blob. Raw key values are never returned
in API responses — only boolean set/unset status.

Backend:
- Add ConfigSecretsStore to BuiltinToolsHandler
- extractAndSaveSecrets: parse api_key from settings, save to
  config_secrets, strip before persisting to builtin_tool_tenant_configs
- getSecretsStatus: returns boolean map per tool (never raw values)
- Enriched handleList response with secrets_set per tool

Frontend:
- Per-provider API key input in web search chain cards
- "Key set" status badge when key exists, "Change" button to replace
- Staged keys sent with settings on save, backend extracts

* feat(vault): tree sidebar with lazy-load folder hierarchy

Replace flat paginated document list with collapsible tree view.
Backend: two-query-per-level approach (files + DISTINCT deeper paths
for virtual folder derivation), path parsing in Go for PG+SQLite
compatibility, text_pattern_ops index for prefix range scans.
Frontend: VaultTree component with doc_type colored icons, compact
single-line nodes, truncate-middle filenames, scope dots, hover
tooltip for date. Sidebar expanded to 384px on large screens.

Also fixes pre-existing SQLite scanVaultDocRow missing path_basename.

* fix(tools): add missing tools to goclaw group and relax agent update ownership

- Add 10 missing tools to the goclaw group in policy.go: skill_manage,
  publish_skill, use_skill, delegate, memory_expand, knowledge_graph_search,
  vault_search, create_audio, datetime, heartbeat. Fixes skill creation
  permission denied when agents use group:goclaw allow list.

- Relax agent update ownership check: tenant admins can now update any
  agent in their tenant (adminMiddleware + tenant-scoped GetByID already
  ensures proper authorization). Previously only agent owner or system
  owner could update.

- Improve agent update error logging: include user_id and tenant_id in
  structured log, return actual error message instead of generic
  "internal error" for better debugging.

* fix(vault): agent filter support + rescan agent_key path matching

- Add AgentID to VaultTreeOptions, pass agent_id filter through
  backend tree endpoint and frontend hook
- Fix rescan inferOwnerFromPath: match root-level {agent_key}/...
  folders against agentMap (workspace uses agent_key directly,
  not agents/ prefix). Keep legacy agents/ prefix for compat
- Preserve full relPath for DB storage in all patterns
- Show filename with extension in tree (use path basename, not title)
- Start tree folders collapsed (prevent stuck loading state)
- Remove orphaned useVaultGraphData call from vault-page
- Tenant isolation verified: agentMap built per-tenant via scopeClause

* fix(vault): reset enrichment progress counter on rescan start

Start() now resets done=0 before broadcasting, preventing stale
counter from previous run causing progress bar to jump/reset.

* fix(vault): only reset enrichment progress on new batch, not mid-drain

Start() is called each drain loop in processBatch to update total.
Only reset done=0 when transitioning from idle→running (new batch),
not when already running (same batch, total growing).

* fix(vault): aggregate enrichment progress across per-agent batches

After rescan agent_key fix, docs split into per-agent batch queues.
Each batch was calling Start()/Finish() independently, causing the
progress bar to flash 0/1 per agent instead of showing global progress.

Now: handler Start(total) sets global count, worker batches call
TrackBatch()/MarkBatchDone() for lifecycle, AddDone(n) auto-completes
when done >= total. Progress bar shows smooth 0→N across all agents.

* fix(vault): increase classify max_tokens to prevent truncated JSON

With 10 candidates, classify response can exceed 1024 tokens when
ctx descriptions are verbose, causing json unmarshal failures.
Bump to 2048 to accommodate worst-case 10-candidate responses.

* fix(vault): enrichment pipeline reliability + cross-agent classify

9 fixes for vault enrichment pipeline:

1. Queue key = tenant-only (was per-agent, caused multiple batches
   blocking EventBus workers and progress bar flashing)
2. Classify chunks 5 candidates per LLM call (prevents response
   truncation that caused parse_still_failed errors)
3. Classify prompt improved: explicit "EXACTLY one entry per
   candidate", 5-entry example, ctx capped at 30 words
4. max_tokens kept at 1024 (sufficient for 5 candidates)
5. Progress AddDone removes !running guard (safe before Start)
6. Rescan defers event publishing via PendingEvents — Start()
   called before workers receive events, eliminating race
7. Upload handler same deferred publish pattern
8. Frontend enrichment timer cancels stale "complete" timeout
   when new enrichment starts (prevents bar disappearing)
9. Sidebar tree reloads after rescan completes

Classify now searches across entire tenant (empty agentID) to
build cross-agent links for future vault sharing. Access control
enforced at query time — agents only see their own docs.

* fix(agents): prevent NOT NULL violation on promoted columns during update

Frontend sent null for empty emoji (emoji.trim() || null), which violated
the NOT NULL constraint on the promoted emoji column (migration 000037).
This caused all agent saves to fail with 500 when emoji was unset.

- Frontend: send empty string instead of null for emoji field
- Backend (PG + SQLite): add null-coercion for all promoted NOT NULL
  columns — TEXT (emoji, agent_description, thinking_level) coerce to "",
  INT (skill_nudge_interval, max_tokens) coerce to 0

* fix(vault): increase max_tokens + hot-reload provider for enrichment

- Increase classify max_tokens 1024→2048, summarize 1536→4096 to
  prevent truncated JSON from models like gemini-2.5-pro
- Add debug logging: raw LLM output on parse failures, finish_reason
  truncation warnings with model name
- Hot-swap vault enrichment provider/model on config change without
  restart (wired into TopicSystemConfigChanged handler)
- Use RWMutex-guarded llm() accessor for thread-safe provider reads

* fix(vault): wire provider hot-reload to config.patch event

The previous commit only listened to TopicSystemConfigChanged (periodic
DB refresh), but config.patch from UI fires TopicConfigChanged. Add
subscriber in gateway_lifecycle so vault enrichment picks up provider/
model changes immediately when user saves config.

* refactor(workers): per-tenant provider resolution for background workers

Replace static provider/model fields with per-tenant resolution at
processing time. Fixes architectural mismatch where singleton workers
used tenant-specific system_configs.

Changes:
- Add shared ResolveBackgroundProvider() in providerresolve package
- Refactor vault enrichWorker, episodic, dreaming workers to resolve
  provider per-event using registry + systemConfigs
- Remove hot-reload machinery (no longer needed)
- Update ConsolidationDeps to use Registry/SystemConfigs

Fallback chain: background.provider → agent.default_provider → first
registered provider.

* feat(vault): add enrichment stop button + error toast

Backend:
- Add error tracking to EnrichProgress (error_count, last_error)
- Broadcast error events when LLM calls fail
- Add POST /v1/vault/enrichment/stop endpoint
- Wire enrichWorker to VaultHandler for stop functionality

Web UI:
- Add stop button (appears when enriching)
- Show error toast when enrichment errors occur
- Display error count in progress bar
- Add useStopEnrichment hook

i18n: en/vi/zh translations for new strings

* fix(providerresolve): add debug logging for background provider resolution

- Log loaded system_configs (background.provider, agent.default_provider)
- Log provider lookup attempts with source and error details
- Warn when falling back to first registered provider
- Surface config load errors instead of silently swallowing them

Helps diagnose provider resolution failures in episodic/vault workers.

* fix(telegram): preserve Telegram topic routing for delayed notifications (#850)

* Fix delayed Telegram topic routing

* refactor: export TaskLocalKeyMetadata and fix formatting

- Export TaskLocalKeyMetadata from tools package for reuse
- Remove duplicate taskLocalKeyMetadata from tasks package
- Fix gofmt indentation issue in notifyLeaders
- Add trailing newline to team_tool_helpers_test.go

* feat(pancake): comment auto-reply + first-inbox DM (#841)

* feat(pancake): add comment auto-reply + first-inbox inbox implementation

- Route COMMENT webhook events with feature gate and self-reply prevention
- Add PostFetcher with sync.Map cache + singleflight for comment context
- Implement ReplyComment() and PrivateReply() API client methods
- Split Send() into sendCommentReply() / sendInboxReply() flows
- Add sendFirstInbox() for one-time inbox DM with configurable greeting
- New config: Features.FirstInbox, CommentReplyOptions, FirstInboxMessage, PostContextCacheTTL
- 72 tests passing with race detection; both PG and SQLite builds clean

* fix(pancake): address PR 841 review issues

- Add slog.Debug when post context fetch fails in buildCommentContent
- Add comment to GetPosts explaining why it bypasses doRequest
- Add 72h TTL eviction for firstInboxSent in runDedupCleaner
- Add 30s timeout to sendCommentReply to bound API hang risk
- Replace custom containsStr helper with strings.Contains in tests

* fix(pancake): correct test assertion and remove unused config field

- Fix TestPrivateReply_ReturnsError: use HTTP 400 instead of 200 since
  doRequest only returns error for status >= 400
- Remove unused MaxThreadDepth config field from CommentReplyOptions

* fix(pipeline): block_reply dedup falsely suppresses final message (#838)

Only count BlockReplies when tool calls are present (matching when
EmitBlockReply actually fires in think_stage). Final answers without
tool calls must not increment the counter, otherwise gateway dedup
falsely suppresses delivery on non-streaming channels.

- Update ObserveStage to check len(resp.ToolCalls) > 0
- Rename test to reflect new behavior (tool calls required)
- Add regression test for #838 scenario

Closes #838

* feat(skills): multi-skill ZIP upload with hash-based idempotency (#846)

feat(skills): multi-skill ZIP upload with hash-based idempotency

- Multi-skill ZIP detection: upload single ZIP containing multiple skill directories
- Hash-based idempotency: SHA-256 of SKILL.md content deduplicates re-uploads
- Grouped upload UI: ZIP group headers with per-skill badges (NEW/UNCHANGED/ERROR)
- Safety: 50-skill per-ZIP limit, TOCTOU-safe hash check under lock
- Performance: cached ZIP parsing O(N) vs O(N*M)
- Tests: 17 frontend + 9 backend tests

Closes #845

* fix(web): add test scripts to package.json

Add vitest scripts for running tests:
- test: run tests once
- test⌚ watch mode
- test:ui: vitest UI

* fix(sqlitestore): add tenant_id filter to GetSkillHashBySlug and GetNextVersion

SQLite implementations were missing tenant_id WHERE clauses that the
PostgreSQL equivalents have. While Lite edition is single-tenant in
practice, this maintains dual-DB parity and prevents potential issues
if the codebase evolves.

Follows the same pattern as other methods in the file (GetSkillFilePath,
CreateSkillManaged, etc.) that use store.TenantIDFromContext with
MasterTenantID fallback.

* feat(web): add ESLint 10 with flat config and CI integration

- Install ESLint 10 + TypeScript-ESLint + React hooks plugins
- Create eslint.config.js with flat config format
- Fix conditional hooks violations in agents-page, task-list, knowledge-chart
- Fix unused variables and useless assignments
- Add lint step to CI workflow before build
- Remove unused eslint-disable comments

Rules configured:
- rules-of-hooks: error (critical)
- exhaustive-deps: off (intentional patterns)
- no-explicit-any: off (pragmatic casts)
- no-console: off (dev convenience)

* fix(vault): re-enqueue unenriched docs on rescan when all files unchanged

When rescan finds no new/updated files but some docs still lack summaries
(e.g. previous enrichment failed due to provider timeout), automatically
re-enqueue them for enrichment retry.

- Add VaultStore.ListUnenrichedDocs() to fetch docs with empty summary
- Add EnrichWorker.EnqueueUnenriched() to emit events for retry
- Add RescanResult.Reenqueued field to track re-enqueued count
- Update UI to show "X re-queued for enrichment" toast

* refactor(vault): merge rescan and stop enrichment buttons into single toggle

* fix(vault): increase classify max_tokens to 4096 for verbose models

* fix(vault): stricter classify prompt - ctx under 50 chars, compact JSON example

* feat(vault): add confirmation dialog for stop enrichment button

* feat(vault): auto-expand first level folders in sidebar by default

* fix(vault): softer graph colors for dark mode, thinner edge lines

* fix(vault): skip goclaw_gen media in enrichment, improve graph UX

Backend:
- Skip goclaw_gen_* files in Handle, EnqueueUnenriched, gatherCandidates
- Skip in RescanWorkspace PendingEvents (progress count)
- Reduces noisy auto-links by ~59%

Frontend:
- Theme-aware node colors (Tailwind -600/-400 matching sidebar)
- Neutral gray edges (zinc-500/300), lighter inactive edges
- Disable hover label white box (defaultDrawNodeHover)
- Auto-expand + load first-level folders
- Group hover text colors for tree items
- Edge density based on camera zoom

* fix(telegram): propagate local_key for forum topic routing in team notifications (#800)

* fix(telegram): propagate local_key for forum topic routing in team notifications

Team task status messages (dispatched, completed, progress) were always
delivered to the General topic in Telegram forum groups because the
notification pipeline had no access to the originating topic's local_key.

Root cause: wireTeamProgressNotifySubscriber in gateway_events.go published
OutboundMessage with no Metadata, so the Telegram adapter had no
message_thread_id to route to the correct forum topic.

Fix has two parts:

1. Team notify path (root cause):
   - Add LocalKey field to TeamTaskEventPayload (protocol)
   - Extract local_key from tool context in WithContextInfo()
   - Add LocalKey to NotifyRoutingMeta
   - Pass LocalKey through to OutboundMessage Metadata in both
     leader mode (InboundMessage) and direct mode (OutboundMessage)

2. MCP bridge context (supporting):
   - Propagate local_key and session_key through bridge HTTP headers
   - Add X-Local-Key and X-Session-Key to BridgeContext
   - Extract and inject into tool context in gateway middleware
   - Include in HMAC signature for integrity

Closes #798

* fix(telegram): pass LocalKey from task metadata in all dispatch/fail broadcast sites

The initial fix added LocalKey to the event payload and WithContextInfo(),
but 4 broadcast call sites use individual With* options instead of
WithContextInfo — so LocalKey was never populated for:

- fallback_dispatch (team_tasks_create.go)
- dispatch_unblocked (team_tool_dispatch.go)
- post_turn dispatch (team_tool_validation.go)
- blocker/fail (team_tasks_blocker.go)

Add WithLocalKey() option function and extract TaskMetaLocalKey from task
metadata at each site, matching the existing TaskMetaPeerKind pattern.

* test(mcp): add HMAC verification tests for extra params (localKey, sessionKey)

- Add tests for SignBridgeContext/VerifyBridgeContext with extra params
- Test backward compat fallback for pre-localKey sessions
- Test that param order matters in signature
- Add clarifying comment for routing context injection security model

-          <p>
-            This PR has no product UI. The reviewer surface is wire behavior:
-            how long tool-call IDs are serialized and how prefixed OpenAI-compatible
-            model IDs are classified. The visuals below show the exact before/after
-            deltas that matter for issue #532.

-            The original defensive fallback capped IDs by slicing the first 40 characters.
-            That stops the HTTP 400, but it still lets two distinct long IDs collapse into
-            the same wire value if they only diverge after character 40.

-              <strong>Why this was still a blocker</strong>
-              <p>Fresh live tool calls were already hashed upstream, but resumed history and replay paths still depended on the serializer. That meant the bug could survive in exactly the sessions reviewers care about: legacy, resumed, or replayed state.</p>
-            </div>
-            <div class="callout">
-              <strong>Why the serializer fix is the right layer</strong>
-              <p>Every OpenAI-compatible request path uses the same request builder. Fixing the boundary closes the main loop and the side loops together instead of patching each caller independently.</p>

 - **Store layer:** Interface-based (`store.SessionStore`, `store.AgentStore`, etc.) with shared Dialect pattern in `store/base/`. PostgreSQL (`pg/`) and SQLite (`sqlitestore/`) implementations use `database/sql` + `pgx/v5/stdlib` + sqlx, raw SQL, `BuildMapUpdate()` and `BuildScopeClause()` helpers
 - **Agent types:** `open` (per-user context, 7 files) vs `predefined` (shared context + USER.md per-user)
+- **Agent identity:** Dual-identity pattern (agent_key vs UUID) applies to agents, teams, tenants. Rule: UUID for DB/FK/events, agent_key for logs/paths/UI. See `docs/agent-identity-conventions.md`

@@ -196,6 +197,7 @@ Go conventions to follow:
 - **SQL safety:** When implementing or modifying SQL store code (`store/pg/*.go`), always verify: (1) All user inputs use parameterized queries (`$1, $2, ...`), never string concatenation — prevents SQL injection. (2) Queries are optimized — no N+1 queries, no unnecessary full table scans. (3) WHERE clauses, JOINs, and ORDER BY columns use existing indices — check migration files for available indexes
 - **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.

+`RoleAdmin` checks role, not tenant. A non-master tenant admin holds `RoleAdmin` in their own tenant and passes role-only middleware. Pick the guard by the **target table**:
+
+| Target | Example | Guard |

+
+**Anti-patterns flagged in review:**
+- `store.Update(...)` on a no-`tenant_id` table without a master-scope check upstream
+- Write SQL with `WHERE ... (tenant_id = $N OR tenant_id IS NULL)` — the `IS NULL` arm lets tenants reach system rows
+- `requireAuth(RoleAdmin)` as the **sole** gate on a global-state write
+- Admin revoke/delete handlers that skip pre-fetch ownership verification (store SQL alone is not enough when it matches `IS NULL` arms)

+## 14. Per-Tenant Tool Configuration
+
+Tools expose configuration via a **4-tier overlay** resolved at Execute time. Callers read the merged view through `tools.BuiltinToolSettingsFromCtx(ctx)` — no tool-interface changes, no per-tenant tool instances.
+
+### Resolution order (high → low)
+
+```
+Execute(ctx, params) → BuiltinToolSettingsFromCtx(ctx)
+  1. Per-agent override  (agents.builtin_tool_settings)
+  2. Tenant override     (builtin_tool_tenant_configs.settings)
+  3. Global default      (builtin_tools.settings)
+  4. Hardcoded default   (embedded in Go)
+```
+
+Merge is tool-name keyed: each tool's config is an independent JSON object; the highest-priority tier with a non-nil value wins (no deep merge). Resolver lives in `internal/tools/context_keys.go`.
+
+### Opt-in for tool authors
+
+Reading `BuiltinToolSettingsFromCtx(ctx)` auto-participates in the overlay:
+
+```go
+func (t *MyTool) Execute(ctx context.Context, params MyParams) (*Result, error) {
+    settings := tools.BuiltinToolSettingsFromCtx(ctx)
+    cfg := t.defaults
+    if raw, ok := settings["my_tool"]; ok {
+        _ = json.Unmarshal(raw, &cfg) // fall back to defaults on error
+    }
+    return t.doWork(ctx, cfg, params)
+}
+```
+
+### Secret vs non-secret split
+
+- **Non-secret** → `builtin_tool_tenant_configs.settings` (tool authors own the schema): provider priorities, `max_results`, `allowed_domains`, UI-tunable params
+- **Secret** → `config_secrets` (already tenant-scoped): API keys, tokens
+
+The overlay does **not** validate the split. Tool authors must never put credentials in `settings`. Current adopters: `web_search` (Exa/Tavily/Brave/DuckDuckGo provider chain), `create_image`/`read_image`/`create_audio`/`read_audio` (Gemini/OpenAI/Qwen chain), `web_fetch` (allowlist policy), `knowledge_graph_search` (traversal config).
+
+### Cache invalidation
+
+Changes propagate via `bus.TopicCacheBuiltinTools` with tenant scoping (Phase 1 refactor, commit `d77a3664`). Handler emits `emitCacheInvalidate(toolName, tenantID)` → subscribers wipe cached loop contexts → next agent turn re-resolves.
+
+### Security: master-scope guard pattern
+
+Writes to global tables (e.g. `PUT /v1/tools/builtin/{name}` touching `builtin_tools`) require **master tenant scope**, enforced by `http.requireMasterScope(w, r)` symmetric to `requireTenantAdmin`. Non-master tenant admins must use the `/tenant-config` endpoint. Same predicate (`store.IsMasterScope(ctx)`) guards WS `config.*`. See commit `6d7473b5` (Phase 0b hotfix) + `plans/260412-0726-tenant-tool-config-refactor/phase-0b-tenant-scope-hotfix.md`.
+
+```go
+func (h *MyHandler) handleWrite(w http.ResponseWriter, r *http.Request) {
+    if !requireMasterScope(w, r) { // reject non-master; 403 written
+        return
+    }
+    // ... global mutation
+}
+```
+
+Tenant-scoped writes use the symmetric `requireTenantAdmin(w, r, tenantStore)` instead.
+
+---
+
+## 14. Per-Tenant Tool Configuration (4-Tier Overlay)
+
+Tenant admins can override tool config without affecting other tenants or master. Overlay priority (most specific wins):
+
+```
+Tool call Execute(ctx, params)
+  ↓
+BuiltinToolSettingsFromCtx(ctx) returns merged map:
+  1. Per-agent override   (agents.builtin_tool_settings; reserved for future)
+  2. Tenant override      (builtin_tool_tenant_configs.settings column)
+  3. Global default       (builtin_tools.settings column, resolver-loaded)
+  4. Hardcoded fallback   (tool internal default when no entry exists)
+```
+
+Each tool that needs tenant-aware config calls `BuiltinToolSettingsFromCtx(ctx)` and unmarshals its settings key. Merge happens at tool-name level: tenant entry for `web_search` wins wholesale over global, no deep field-level merge.
+
+**Opt-in pattern** — Any tool can participate by:
+```go
+func (t *MyTool) Execute(ctx context.Context, params MyParams) (*Result, error) {
+    settings := tools.BuiltinToolSettingsFromCtx(ctx)
+    var cfg MyToolConfig = t.defaults
+    if raw, ok := settings["my_tool"]; ok {
+        if err := json.Unmarshal(raw, &cfg); err != nil {
+            slog.Warn("my_tool: invalid tenant settings, using defaults", "error", err)
+        }
+    }
+    return t.doWork(ctx, cfg, params)
+}
+```
+
+### Schema Contracts
+
+#### web_search (tenant override shape)
+```json
+{
+  "provider_order": ["exa", "tavily", "brave", "duckduckgo"],
+  "exa": { "enabled": true, "max_results": 10 },

+  "blocked_domains": ["malicious.com"]
+}
+```
+
+#### tts (tenant override shape)
+```json
+{
+  "primary": "elevenlabs"
+}
+```
+
+**Secret vs non-secret split:**
+- Non-secret (provider priorities, max_results, allowed_domains): `builtin_tool_tenant_configs.settings` (editable via UI)
+- Secret (API keys): `config_secrets` table (encrypted, tenant-scoped)
+
+Never put credentials in tool settings JSON — backend does not validate.
+
+### Tenant Admin Workflow
+
+1. Log in as tenant admin → Settings → Builtin Tools
+2. Click gear icon next to a tool → JSON editor opens
+3. Edit settings per schema contracts above → Save
+4. Changes take effect immediately on next agent turn (cache invalidated via pub/sub)
+5. Click "Reset to default" to revert to platform defaults
+
+### Feature Flag: Tenant-Scoped Singleton Pools
+
+`config.Tools.TenantScopedSingletons` (default: false) gates Phase 8 refactor — per-tenant connection pool instances for stateful tools (TTS manager, web_fetch policy validator). Disable for legacy singleton behavior. Enable after 1-week staging smoke test.

@@ -367,6 +367,59 @@ When enabled, each thread gets an isolated session:
 - Different threads within the same group maintain separate conversation histories
 - Disabled by default
 
+### Thread Reply Routing
+
+When a message is sent inside a Lark thread (detected via the `thread_id` field in the inbound event), the inbound handler stamps `metadata["feishu_reply_target_id"]` with the triggering message ID. During outbound delivery, the channel routes responses back to the same thread using `LarkClient.ReplyMessage()` which POSTs to `/open-apis/im/v1/messages/{message_id}/reply` with `reply_in_thread: true`.
+
+- **Automatic thread detection**: No configuration needed; replies are routed based on inbound `thread_id`
+- **Metadata propagation**: The `feishu_reply_target_id` key is included in the `routingMetaKeys` allowlist so replies, block replies, and placeholder updates all land in the correct thread
+- **Graceful fallback**: If the reply endpoint fails (e.g., thread root deleted), the channel falls back to `SendMessage()` for the regular chat
+- **Applies to**: Text, card, image, and file messages
+
+### Document URL Auto-Fetch
+
+When a user pastes a Lark docx (document) URL in a message, the channel automatically fetches the document raw text and injects it into the agent prompt for context.
+
+**URL detection**: Regex pattern matches `https://*.larksuite.com/docx/<id>` and `*.feishu.cn/docx/<id>` URLs.
+
+**Auto-fetch behavior**:
+- Document content fetched via Lark API `GET /open-apis/docx/v1/documents/{id}/raw_content`
+- Content injected as `[Lark Doc: <url>] ... [End of Lark Doc]` markers around the raw text
+- Rune-safe truncation at 8000 runes per document to respect token budgets
+- Results cached per channel instance with LRU eviction (128 entries, 5-minute TTL)
+
+**Access control**: Requires bot app to have `docx:document:readonly` permission **and** document owner must explicitly grant the bot access to each document. If access is denied or document not found, a visible inline marker appears: `[Lark Doc X: access denied — grant the bot app read permission on this document]`
+
+**Safeguards**:
+- Limited to docx documents only (sheets, base, wiki deferred)
+- Maximum 10 document fetches per inbound message (spam protection)
+- Soft-fail on API errors (no outbound message blocks)
+
+**Configuration**: No new config flags. Supported document type and cache tunables (8000 rune limit, 10-URL cap, 5-min TTL, 128-entry cache) are hardcoded.
+
+### Writer Management Commands
+
+Group chats support file-write permission management via slash commands. Permissions are scoped to the group via `group:feishu:<chatID>`. DM users who attempt these commands receive a hint that they only work in groups.
+
+**Commands** (group-only):
+
+| Command | Description | Requires Target | Permission |
+|---------|-------------|:---:|:---:|
+| `/addwriter <@user or reply>` | Grant file_writer permission to target user | Yes | Writers only |
+| `/removewriter <@user or reply>` | Revoke file_writer permission from target user | Yes | Writers only |
+| `/writers` | List current group writers with displayName | No | -- |
+
+**Target specification**: Commands require explicit identification via reply-to or @mention. Bare `/addwriter` without a target is rejected — prevents accidental privilege capture.
+
+**Bootstrap behavior**: Groups with no writers allow the first writer to grant themselves via `/addwriter @self` (explicit self-mention). This enables initial configuration without external admin intervention.
+
+**Authorization**:
+- Only existing writers can manage the writer list (enforce via `IsGroupFileWriter` check)
+- Last-writer guard: If removing a writer would leave zero writers, operation is rejected with user-facing message
+- Database errors are fail-open; security issues are logged as `security.writer_check_failed`
+
+**Implementation**: Timeout of 10 seconds bounds Feishu API calls. Requires `AgentStore` and `ConfigPermissionStore` wired to the Feishu channel via constructor options.

+### Security
+
+#### Tenant-Scope Hotfix (2026-04-12)
+
+3 privilege-escalation vulnerabilities closed, same class as `b419f352` (Phase 1 `config.*` hotfix):
+
+- **CRITICAL** `PUT /v1/tools/builtin/{name}` — non-master admin could corrupt global tool defaults
+- **CRITICAL** `POST /v1/packages/install|uninstall` — non-master admin could run `pip`/`npm`/`apk` server-wide
+- **HIGH** `POST /v1/api-keys/{id}/revoke` (HTTP + WS) — tenant admin could revoke NULL-tenant system keys
+
+Fix adds shared `store.IsMasterScope(ctx)` predicate + `http.requireMasterScope` guard on all three endpoints. `APIKeyStore.Delete` dropped (YAGNI + dormant same-class vuln). WS router now injects role into ctx. Tests: 17 new unit tests. Audit: `plans/reports/debugger-260412-0922-tenant-scope-audit.md`.
+
+### Added
+
+#### Per-Tenant Tool Configuration — 4-Tier Overlay (2026-04-12)
+
+Tenant admins can override tool configuration without affecting other tenants. Overlay: `per-agent > tenant > global > hardcoded`, resolved at Execute time via `tools.BuiltinToolSettingsFromCtx(ctx)` — no Tool interface changes. See `docs/03-tools-system.md` § 14. Applies to `web_search`, `web_fetch`, `tts`. Web UI dialog is tenant-scope aware.
+- **Phase 5** (1e5e84d5): Builtin tools settings editor on web UI
+- **Phase 7 rest** (30a40bbe): Exa + Tavily web search providers with ranked ordering via `provider_order` config. Credit: @kaitranntt for original PR 825 work, ported to tenant settings storage pattern
+  - New files: `internal/tools/{web_search_exa,web_search_tavily,web_search_config}.go`
+  - 11 new unit tests for provider chain + normalization
+  - Provider-selection helper: `NormalizeWebSearchProviderOrder(order []string) → []string` (DuckDuckGo always last as free fallback)
+- **Phase 8** (def1712f, 43ee918b): Tenant-aware singleton pool pattern for stateful tools
+  - `web_fetch`: Domain policy override via `resolvePolicy(ctx)` reads tenant config; 6 new unit tests
+  - `tts`: Primary provider override via `resolvePrimary(ctx, mgr)` reads tenant config; 5 new unit tests
+  - Feature flag: `config.Tools.TenantScopedSingletons` (default: false) gates per-tenant pool instances with LRU eviction (64 tenants) + 30 min idle timeout
+
+### Fixed
+
+#### 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
+- **Phase 2 — Document auto-fetch**: Pasted Lark docx URLs auto-detected and fetched via `/open-apis/docx/v1/documents/{id}/raw_content`. Content injected as `[Lark Doc: URL]` markers. LRU cache (128 entries, 5-min TTL) + 8000-rune truncation per document. Requires `docx:document:readonly` permission + owner grant
+- **Phase 3 — Writer management commands**: Added `/addwriter <@user or reply>`, `/removewriter`, `/writers` for group file-write permission control. Group-only (DMs rejected early). Requires existing writer authorization. Last-writer guard prevents removing final writer. Empty-writer groups allow bootstrap via explicit `/addwriter @self`. 10s timeout bounds Feishu API calls

+### Testing
+
+#### Test Speed-Up + Coverage Ratchet Removal (2026-04-11)
+- **Philosophy shift**: Signal over coverage %. Reject mock-heavy/slow/low-signal tests even if % drops. Coverage ratchet gate removed — was creating pressure to write forced tests instead of fast, valuable ones
+- **`internal/vault` retry tests**: 16.3s → 0.6s. New `fastBackoffsForTest(t)` helper overrides package-level `enrichRetryBackoffs`/`enrichRetryTimeouts` so retry tests don't wait through real exponential backoff (was 6s per all-retry test). Production behavior unchanged
+- **`internal/cron` scheduler tests**: 11.7s → 1.5s. `runLoopTickInterval` extracted as package var (default 1s, unchanged); test-only `setFastTick(t)` helper overrides to 20ms so 6 scheduler tests don't sleep 1.5s each waiting for ticks
+- **`internal/channels/facebook` retry tests**: 6.3s → 3.0s. `graphBackoffBase` extracted as package var (default 1s, unchanged); `newFakeGraph` helper overrides to 1ms so HTTP retry tests don't burn 3+2+1s of real waits
+- **Vault duplicates removed**: `TestCallClassifyWithRetry_FirstAttemptSuccess` (dup of `_Success`) and `_MaxRetriesConstant` (dup of `_RetriesAndBackoffs`)
+- **Total saved**: ~29s wall-clock (3 packages: 34.3s → 5.1s). Full `go test -race ./...` now runs in ~57s (was ≥90s with hangs)
+- **Removed**: `scripts/check_coverage.go` + `scripts/coverage_thresholds.json` + "Coverage ratchet gate" CI step. Coverage profile + `go tool cover -func` summary preserved as informational only
+
+#### Test Coverage Improvement — Wave 1-3 (2026-04-11)
+- **CI ratchet gate**: `scripts/check_coverage.go` parses `coverage.out` per package and fails CI if coverage drops below stored floors in `scripts/coverage_thresholds.json`. `--update` flag ratchets thresholds upward when coverage improves. 61 packages locked.
+- **`-coverpkg=./...`**: CI now runs `go test -race -coverpkg=./...` so integration tests in `tests/integration/` are attributed to the source packages under test.
+- **`internal/testutil`**: shared helpers — `TestDB()` (integration-tagged), context builders (`TenantCtx`, `UserCtx`, `AgentCtx`, `FullCtx`), mockgen generate hooks for `SessionStore`/`AgentStore`/`ContactStore`.
+- **~663 new test functions across 36 files**:
+  - Wave 1 — `store/pg` integration test depth (session pagination/isolation, agent context files/profiles, agent_links CRUD, cron CRUD+state, vault CRUD/search, memory BM25/isolation); `gateway` unit tests (ratelimit, event_filter, server auth); `gateway/methods` handlers (sessions, skills, cron); `http` auth helpers + path security; `tasks.TaskTicker` (lifecycle, recoverAll, followupInterval); `agent` (pruning, extractive memory, intent classify, loop utils, inject, evolution guardrails).
+  - Wave 2 — `config` (normalize, expand/contract home, env overlays, system configs); `skills` (BM25 tokenize/index/search/rebuild, frontmatter parser, loader/context); `mcp` (pool, manager status, bridge BM25, env resolution); `backup` (ArchiveDirectory, SanitizeDSN, WritePgpass, Backup.Run); `channels/slack` (mention, user cache, classifyMime); `channels/discord` (resolveDisplayName, command routing, classifyMediaType); `channels/telegram` (markdown→HTML, table rendering, detectMention, service message); `channels/whatsapp` (extractTextContent, chunkText, markdown→WhatsApp, mimeToExt, classifyDownloadError).
+  - Wave 3 — `cache.PermissionCache` (9 methods + invalidation); `sessions` key builders + manager edge cases; `knowledgegraph` extractor (mock provider success/filter/error/invalid-JSON/long-text chunking), splitChunks, mergeResults.
+- **Coverage deltas** (local `go test`, no DB):
+  - `internal/knowledgegraph` 47.1% → 91.8% (+44.7pp)
+  - `internal/skills` 7.7% → 37.5% (+29.8pp)
+  - `internal/config` 19.3% → 48.2% (+28.9pp)
+  - `internal/cache` 72.9% → 96.9% (+24.0pp)
+  - `internal/sessions` 70.7% → 94.4% (+23.7pp)

+  - `internal/mcp` 12.1% → 26.3% (+14.2pp)
+  - `internal/channels/whatsapp` 8.8% → 21.3% (+12.5pp)
+  - `internal/channels/discord` 15.6% → 27.7% (+12.1pp)
+  - `internal/tasks` 0% → 55.4%
+  - `internal/agent` 28.8% → 36.8%
+  - store/pg integration test depth improved — coverage attribution requires live pgvector in CI
+- **Deferred to separate plans**: `channels/feishu` (0%, 102 funcs), `providers/acp` (0%, 41 funcs), `channels/zalo` (regressed to 5%), `providers` (56%, 325 funcs), `channels/facebook` (31.8%)
+
+#### Deferred Coverage Waves A-C — Resolved (2026-04-11)
+Follow-up to Wave 1-3 above. Addresses the 6 modules deferred as too-large/greenfield/regression. Plan: `plans/260411-2020-deferred-coverage-waves/`.
+- **Wave A** — `internal/providers` 57.0 → 62.5% (hotspot tests for adapter/retry/SSE); `channels/zalo` 7.2 → 65.3% (regression fix + parse/policy/HTTP coverage)
+- **Wave B** — `channels/facebook` 23.1 → 81.9% (full bot lifecycle, media, policy); `store/pg` 1.3 → 3.5% (⚠️ capped at unit-test-only; 30% target requires CI integration wiring + pre-existing failing tenant-isolation tests — deferred separately)
+- **Wave C** — `providers/acp` 0.0 → **80.0%** greenfield (7 test files, 2560 LOC; JSON-RPC framing with adversarial input fuzz, terminal sandbox + allowlist + deny-pattern enforcement, ProcessPool lifecycle, tool_bridge with 3 permission modes); `channels/feishu` 20.6 → **63.9%** (15 test files; AES-CBC webhook decrypt + tamper detection, WS proto framing, larkclient HTTP error paths, media send/receive, bot parse/policy, lifecycle)
+- **Security tests added**: ACP JSON-RPC parser no-panic on 7 adversarial inputs; sandbox path-traversal + binary allowlist + deny-pattern (`rm -rf` even under `bash`); env sanitization strips 8 prefixes + 13 exact-name vars (GOCLAW/ANTHROPIC/OPENAI/DATABASE/AWS/GITHUB/SSH/STRIPE/DB_DSN/PG*/NPM_TOKEN/SECRET_KEY/JWT_SECRET). Feishu AES-CBC tamper detection + token mismatch drop; no real credentials in any fixture
+- **Scale**: ~375 new test functions across 22 files (~5858 LOC); zero source modifications — pure additive coverage
+- **Ratchet bumped**: `scripts/coverage_thresholds.json` — feishu 0 → 63.89, acp 0 → 80.05

+# Agent Identity Conventions — `agent_key` vs `UUID`
+
+> Dual-identity rules for agents, teams, and tenants. Read this before touching any code path that handles identifier strings, DomainEvents, SQL `WHERE agent_id`, router cache, or system prompts.
+
+## 1. Core rule
+
+**Question to ask for every identifier:**
+
+> *Does this identifier ever touch the DB layer or need to be unique system-wide?*
+>
+> - **Yes** → use `UUID`
+> - **No** (display / path / template / log only) → use `agent_key`
+
+Vietnamese phrasing used by the team:
+
+> *"Cái identifier này có bao giờ đụng vào DB layer hoặc cần unique toàn hệ thống không? Có → UUID. Không → agent_key."*
+
+There is no third option. Every site that handles an `AgentID`, `TenantID`, or `TeamID` string must answer this question.
+
+## 2. Decision table
+
+### 2.1. MUST use UUID
+
+| Use case | Reason | Example |
+|---|---|---|
+| SQL `WHERE`/`JOIN`/`INSERT` on `agent_id` column | DB column type is `uuid` | `episodic_summaries.agent_id`, `kg_entities.agent_id` |
+| Store model struct field | Compile-time type safety | `store.EpisodicSummary.AgentID uuid.UUID` |
+| `store.WithAgentID(ctx, ...)` | Downstream SQL query context | `loop_context.go` |
+| `eventbus.DomainEvent.AgentID` ⚠️ | Consumer workers parse and query DB with it | `episodic_worker`, `semantic_worker`, `dreaming_worker` |
+| OpenTelemetry span attribute `agent_id` | Cross-session tracing correlation | `loop_tracing.go` |
+| Tenant-scoped FK (team members, agent_links) | DB constraint enforcement | `TeamMember.AgentID`, `AgentLink.SourceAgentID` |
+| Public HTTP/WS API `AgentID` params | Stable across renames | `params.AgentID` in heartbeat, config, teams methods |
+| `SystemPromptConfig.AgentUUID` | Runtime identification, not exposed to LLM | Paired with `AgentID` (key) |
+
+### 2.2. MUST use agent_key
+
+| Use case | Reason | Example |
+|---|---|---|
+| System prompt template ("You are @X") | LLM/user reads it, must be human-readable | `SystemPromptConfig.AgentID` |
+| Filesystem path segment `agents/{X}/...` | Path is user-visible | `workspace.ResolveParams.AgentID` → `sanitizeSegment()` |
+| WS `AgentEvent` broadcast to UI | UI filters and displays by name | `AgentEvent.AgentID` |
+| Slog log fields (`"agent"` key) | Human-readable when grep'ing logs | `slog.Info(..., "agent", l.id)` |
+| `store.WithAgentKey(ctx, ...)` | Intentional key propagation | `loop_context.go` |
+| `tools.WithToolAgentKey(ctx, ...)` | Tool access identifier | `loop_context.go` |
+| Router cache lookup | Callers have `agent_key` readily available | `router.Get(ctx, agentKey)` |
+| Channel bot identifier (Telegram `@X`) | Users type it in chat | Channels layer |
+| `Loop.ID() string` method | Display API | `loop_tracing.go` |
+
+## 3. Trap zones
+
+Five known identifier trap zones. All are mitigated by the agent identity hardening work (commits `acbfb2e4..d3f37068`). Status per zone below.
+
+### 🪤 Trap 1: `DomainEvent.AgentID` is a `string`
+
+- **Problem:** field type is `string`; the compiler cannot enforce UUID vs key. Publishers nearby only see the type, not the semantic intent. If a publisher writes `AgentID: l.id` instead of `l.agentUUID.String()`, downstream consumers (which `uuid.Parse` and query DB) explode with `invalid input syntax for type uuid`.
+- **Rule:** if ANY consumer calls `uuid.Parse(event.AgentID)` or passes the value down to SQL `WHERE agent_id = $1`, the publisher MUST set a UUID string. Today every production consumer in `internal/consolidation/*` does exactly that.
+- **Status:** Mitigated by the publish-time observer in `internal/eventbus/validate_agent_id.go` — warns with `slog.Warn("eventbus.non_uuid_agent_id", ...)` on any non-UUID drift. Strict type lift to `uuid.UUID` is gated (Phase 5) behind wire-format audit + rolling-deploy coexistence tests.
+
+### 🪤 Trap 2: Struct with both `AgentID` and `AgentUUID`
+
+- **Problem:** `SystemPromptConfig` has `AgentID string` (agent_key) + `AgentUUID string` (UUID). Two adjacent `string` fields are trivially swappable at a callsite.
+- **Rule:** always check field comments or downstream consumer behavior before setting either field. `AgentID` is rendered into the system prompt ("You are @{AgentID}"); `AgentUUID` is for runtime identification and never reaches the LLM.
+- **Status:** Mitigated. The one historical omission (`memoryflush.go` missing `AgentUUID`) is now set. See section 10 for why the omission worked by accident historically.
+
+### 🪤 Trap 3: `mustParseUUID` silently returns `uuid.Nil`
+
+- **Problem:** a store helper named `mustParseUUID` looked like `uuid.MustParse` from the stdlib (which panics), but actually behaved like `uuid.Parse` with the error swallowed — returning `uuid.Nil` on bad input. 88 callsites in `internal/store/pg/`. Passing an `agent_key` in would silently write `agent_id = '00000000-0000-0000-0000-000000000000'` or, for reads, return an empty result / zero-row update.
+- **Rule:** two helpers, two contracts.
+  - `parseUUID(s string) (uuid.UUID, error)` — use for **every** `INSERT`/`UPDATE`/`UPSERT`/`DELETE` and any `SELECT WHERE` where an empty result would hide a bug. Propagate the error. Callers fail fast with a clean Go error instead of a cryptic PG 23503 or a silently corrupted row.
+  - `parseUUIDOrNil(s string) uuid.UUID` — honest rename of the former `mustParseUUID`. Intentionally silent. Only acceptable on read-only `SELECT WHERE` paths where a no-match on bad input is the correct semantics. Prefer `parseUUID` for any new code.
+- **Status:** Mitigated by the `parseUUID` refactor across `internal/store/pg/`. 57 critical write sites migrated. The remaining `parseUUIDOrNil` sites are audited and intentional.
+
+### 🪤 Trap 4: `Router.Get(ctx, X)` accepts both UUID and agent_key
+
+- **Problem:** the router resolver parses either a UUID or an agent_key and returns the same `Loop`. Pre-hardening, the cache key was the raw input string — so the same agent could end up with two cache entries (one under UUID, one under agent_key), defeating invalidation. In addition, `HasSuffix`-based invalidation could collide with unrelated keys that happened to share a suffix.
+- **Rule:** cache entries are **canonicalized** to `tenantID:agentKey` after resolution, regardless of whether the caller passed UUID or key. Invalidation uses exact-segment match, not substring. `IsRunning(ctx, agentKey)` is tenant-aware and requires `tenantID` from context.
+- **Status:** Mitigated. See section 8 for the full cache strategy.
+
+### 🪤 Trap 5: WS method params `AgentID` — inconsistent parsing
+
+- **Problem:** WS handlers variously used bare `uuid.Parse(params.AgentID)`, `resolveAgentUUID(...)`, or passed straight to the router. From the client's perspective there was no single rule for whether to send UUID or agent_key.
+- **Rule:** WS handlers accept **both** UUID and agent_key for `AgentID` params and resolve through a single helper. Hot-path handlers use `resolveAgentUUIDCached` which consults the router cache first and falls back to a DB lookup on miss. Cold-path handlers use `resolveAgentUUID` directly.
+- **Status:** Mitigated. Standardized through `internal/gateway/methods/agent_links.go` helpers.
+
+## 4. Code review sanity checklist
+
+For every new `AgentID:` assignment or new `agent_id` read/write, walk through in order:
+
+### Step 1 — Destination field type?
+
+| Destination type | Required source |
+|---|---|
+| `uuid.UUID` | UUID source only: `l.agentUUID`, `ag.ID`, `store.AgentIDFromContext(ctx)` |
+| `*uuid.UUID` | Same as above, nullable |
+| `string` | → Step 2 |
+
+### Step 2 — If destination is `string`, what does the consumer do with it?
+
+| Consumer behavior | Required identifier |
+|---|---|
+| `uuid.Parse(...)` or passes to SQL `WHERE x = $1` on a uuid column | UUID string |
+| Logs / displays / compares / renders template / builds path | `agent_key` string |
+| Forwards to another consumer | Follow the terminal consumer |
+
+### Step 3 — Double-check with grep
+
+```bash
+grep -rn "\.AgentID" <consumer files>
+```
+
+Look for any `uuid.Parse(...)` or SQL `WHERE agent_id = $1` in the downstream path. If any consumer eventually touches DB, the publisher must supply a UUID.
+
+### Step 4 — Run the regression tests
+
+```bash
+go test ./internal/consolidation/... ./internal/eventbus/... ./internal/store/pg/...
+```
+
+Relevant tests:
+
+- `consolidation/workers_test.go::TestEpisodicWorkerHandle_NonUUIDAgentID` — rejects `"goctech-leader"` with a clean error.
+- `consolidation/workers_test.go::TestEpisodicWorkerHandle_NonUUIDTenantID` — mirror for tenant.
+- `eventbus/validate_agent_id_test.go` — publish-time observer coverage.
+- `store/pg/parseuuid_test.go` — helper contract.
+- `agent/router_cache_canonicalize_test.go`, `router_invalidate_collision_test.go`, `router_isrunning_test.go` — router cache strategy.
+- `gateway/methods/agent_resolve_cached_test.go` — cache-aware resolver.
+
+## 5. How this applies to teams and tenants
+
+The dual-identity pattern is a **codebase-wide convention**, not agent-specific:
+
+| Entity | UUID field | Key field | Notes |
+|---|---|---|---|
+| Agent | `agents.id uuid` | `agents.agent_key text` | Dual-tenant: same key across tenants is allowed |
+| Team | `agent_teams.id uuid` | `agent_teams.team_key text` | Team members reference agents by UUID |
+| Tenant | `tenants.id uuid` | `tenants.tenant_slug text` | Slug used in URLs and onboarding wizard |
+| Session | `sessions.session_key text` | (no separate UUID) | Session key is the only identifier — safe by construction |
+
+The rules in section 2 apply verbatim to `team_id`/`team_key` and `tenant_id`/`tenant_slug`. In particular:
+
+- `WithTenantID(ctx, ...)` takes a `uuid.UUID`. Never pass a slug.
+- `TeamMember.AgentID` is the canonical team-membership FK and must be a UUID.
+- Slog log fields `"tenant"`, `"team"` should receive the human-readable slug/key, not the UUID.
+
+## 6. Post-hardening status
+
+| Trap zone | Status | Guardrail |
+|---|---|---|
+| Trap 1 — `DomainEvent.AgentID` as string | Mitigated (strict type gated) | `eventbus/validate_agent_id.go` publish observer |
+| Trap 2 — `SystemPromptConfig` dual field | Mitigated | `memoryflush.go` + `loop_history.go` set both fields |
+| Trap 3 — `mustParseUUID` silent nil | Mitigated | `parseUUID` error-propagating helper in 57 critical sites |
+| Trap 4 — Router cache fragmentation | Mitigated | Canonical `tenantID:agentKey` keys + exact-segment invalidation |
+| Trap 5 — WS method inconsistency | Mitigated | `resolveAgentUUID` / `resolveAgentUUIDCached` helpers |
+
+Phase 5 (DomainEvent strict-type lift) is **gated** — only starts once Phases 1-4 have been stable on `dev` for ≥72h with zero `eventbus.non_uuid_agent_id` observer warnings, and after a coexistence test covering rolling deploys. Without those signals, the runtime observer is sufficient defense.
+
+## 7. Regression test coverage map
+
+| Test | File | Guards |
+|---|---|---|
+| `TestEpisodicWorkerHandle_NonUUIDAgentID` | `internal/consolidation/workers_test.go` | Trap 1 — consumer fails cleanly on bad `AgentID` |
+| `TestEpisodicWorkerHandle_NonUUIDTenantID` | `internal/consolidation/workers_test.go` | Trap 1 — same for tenant |
+| `TestValidateAgentID_*` | `internal/eventbus/validate_agent_id_test.go` | Trap 1 — publish-time observer warns on drift |
+| `TestParseUUID*` / `TestParseUUIDOrNil*` | `internal/store/pg/parseuuid_test.go` | Trap 3 — helper contract (error vs silent) |
+| `TestRouterGet_Canonicalize*` | `internal/agent/router_cache_canonicalize_test.go` | Trap 4 — UUID and key both map to same canonical cache entry |
+| `TestRouterInvalidate_SuffixCollision` | `internal/agent/router_invalidate_collision_test.go` | Trap 4 — exact-segment invalidation does not collide on substring |
+| `TestRouterIsRunning_*` | `internal/agent/router_isrunning_test.go` | Trap 4 — `IsRunning` is tenant-scoped, not tenant-blind |
+| `TestRouterGet_DualTenantSameAgentKey` | `internal/agent/router_cache_canonicalize_test.go` | Dual-tenant agent_key isolation (see section 13) |
+| `TestAgentResolveCached_*` | `internal/gateway/methods/agent_resolve_cached_test.go` | Trap 5 — cache-aware fast path plus DB fallback |
+| `TestVaultHandlerUpload_*` | `internal/http/vault_handler_upload_test.go` | HTTP form `agent_id` entry point (bypass gap for owner / lite edition) |
+| `TestMemoryFlush_*` | `internal/agent/memoryflush_test.go` | Trap 2 — `SystemPromptConfig.AgentUUID` is set |
+
+## 8. Router cache canonicalization strategy
+
+Cache invariants after hardening:
+
+1. **Key format:** `{tenantID}:{agentKey}`. Computed AFTER the resolver returns an `Agent`. Inputs that arrived as UUID are translated to `agentKey` via the resolved record. No more dual entries.
+2. **Tenant scoping:** all router operations take `ctx` and extract tenant via `store.TenantIDFromContext`. `Router.Get`, `Router.GetCached`, `Router.IsRunning`, and `InvalidateAgent` all require a tenant.
+3. **Invalidation:** exact-segment match on the full canonical key. The previous `strings.HasSuffix(entry, agentKey)` approach could collide when one agent's key was a suffix of another's. Now replaced with exact match against `{tenantID}:{agentKey}`.
+4. **`IsRunning(ctx, agentKey)`:** tenant-scoped. Pre-hardening, the check was tenant-blind and always returned `false` for any tenant whose agent_key collided with another tenant's loop (see section 13).
+
+## 9. Batch fail-fast contract
+
+Pre-hardening: store methods that accepted a batch (vault bulk upload, KG ingest, memory doc batch) called `mustParseUUID` on each row. Bad UUIDs resolved to `uuid.Nil`, the `INSERT` went through, and the DB rejected it via FK code 23503 — **for the first bad row only**. Successfully inserted rows stayed. Callers saw a partial success.
+
+Post-hardening: `parseUUID` errors at parse time. The entire batch fails fast at the first invalid UUID, **before any write happens**. Net contract change:
+
+- Error is raised earlier, not silent-to-loud.
+- Callers that relied on partial success must validate UUIDs up front or split the batch themselves.
+- Clients using bulk operations cannot mix valid and invalid UUIDs in the same call.
+
+**Affected operations:** vault bulk upload, knowledge graph batch ingest, memory documents batch upsert.
+
+This is an intentional contract change and is documented here rather than hidden in a release note, because callers outside this repo (if any) will see the new error type.
+
+## 10. memoryflush historical accident
+
+`memoryflush.go` historically set only `SystemPromptConfig.AgentID` and not `AgentUUID`. This did not cause a bug because `buildRuntimeSection` — the function that consumes `AgentUUID` — runs **after** the `CacheBoundaryMarker` in the assembled system prompt. Anything below the marker is rendered fresh every turn and never feeds into the stable prefix that gets cached by the LLM provider. Missing `AgentUUID` simply meant an empty runtime field in the dynamic suffix. No prompt cache bust, no functional consequence.
+
+The field is now populated unconditionally for consistency with `loop_history.go`, which has always set both fields. Mentioned here because anyone reading the fix is likely to wonder what broke — nothing broke, it was a latent gap that would have become a real bug if `AgentUUID` ever moved above the cache boundary.
+
+## 11. FK as safety net
+
+PostgreSQL and SQLite both enforce FK constraints on `agent_id` → `agents.id`. This is the **primary correctness guarantee** against silent data corruption, not the `parseUUID` refactor.
+
+**PostgreSQL:** all primary phase 4 target tables have an FK with `CASCADE` (or `SET NULL` for nullable columns). Verified against staging on 2026-04-11 across `episodic_summaries`, `kg_entities`, `kg_relations`, `memory_documents`, `memory_chunks`, `vault_documents` — plus 25 other agent-scoped tables. Bad UUIDs are rejected with PG error code 23503.
+
+**SQLite:** `PRAGMA foreign_keys = ON` is applied per-connection via `sqlitestore/pool.go` and `schema.sql`. All `agent_id TEXT` columns declare `REFERENCES agents(id) ON DELETE CASCADE`. Bad input → SQLite constraint error.
+
+**Orphan scan:** staging MCP scan on 2026-04-11 found **zero** rows with `agent_id = '00000000-0000-0000-0000-000000000000'` across 5 NOT-NULL target tables. Self-hosted deployments that predate the FK migrations can run `scripts/scan_orphan_agent_rows.sh` as a pre-flight check before upgrading.
+
+**What the `parseUUID` refactor adds on top of FK:**
+
+- Earlier error detection (before the SQL round-trip).
+- A clean Go error with a descriptive message instead of a driver-layer PG 23503.
+- Coverage for `UPDATE WHERE agent_id = uuid.Nil` and `SELECT WHERE agent_id = uuid.Nil` — FK cannot help on reads or no-op updates. This is where the real silent-bug risk lived post-FK, and the refactor closes it.
+
+**If a future developer misses a `parseUUID` site:** the result is a cryptic PG error at the driver layer, not corruption. The FK safety net still holds.
+
+## 12. Telemetry tables without FK
+
+`spans`, `traces`, `usage_snapshots` do **not** have FK on `agent_id`. Reason: these are append-only, high-volume telemetry tables — FK validation overhead at insert rate would be prohibitive.
+
+**Type-layer defense instead of FK:**
+
+- All struct `AgentID` fields in `store/pg/tracing.go`, `store/pg/snapshot.go`, etc. are `*uuid.UUID`, not `string`.
+- Inserts go through `store/base/helpers.go::nilUUID()` which converts `uuid.Nil → SQL NULL`.
+- There is no `mustParseUUID` call site in telemetry store code — callers cannot pass bare strings. The compile-time contract blocks the trap entirely.
+
+**Residual risk:** if a caller bypasses `nilUUID()` and writes `uuid.Nil` raw, the row lands with `agent_id = '00000000-0000-0000-0000-000000000000'`. Impact is scoped to analytics pollution (these tables feed dashboards, not downstream pipelines). Check with:
+
+```sql
+SELECT count(*) FROM spans WHERE agent_id = '00000000-0000-0000-0000-000000000000'::uuid;
+```
+
+If the count ever rises above zero on production, it is a caller bug in the telemetry emission path — not a store-layer regression.
+
+## 13. Dual-tenant `agent_key`
+
+`agent_key` is unique **only within a tenant**. The same `agent_key` can exist in multiple tenants with different UUIDs. Example from staging (2026-04-11): `tieu-ho` exists in both the Master tenant and the Việt Org tenant under different `agents.id` values.
+
+The unique index is:
+
+```sql
+CREATE UNIQUE INDEX agents_tenant_key_unique
+  ON agents (tenant_id, agent_key)
+  WHERE deleted_at IS NULL;
+```
+
+Consequences for code:
+
+- **Never** use bare `agent_key` as a global identifier. It is only unique inside a tenant.
+- `Router.Get(ctx, "tieu-ho")` requires `tenantID` from ctx. Without tenant scoping, the lookup is ambiguous across tenants.
+- Cache entries are keyed as `{tenantID}:{agentKey}` (section 8).
+- Log formatting: prefer `{"agent": "tieu-ho", "tenant": "master"}` together, or just the UUID. Never log `agent_key` alone without a tenant.
+- When designing new tables with agent_key columns, the unique index must include `tenant_id`. Scoping to tenant_id prevents the same error class in future features.
+
+## Appendix — TL;DR one-liner
+
+- Use **`l.agentUUID.String()`** when setting `DomainEvent.AgentID`, store model fields, SQL query parameters, OTel span attributes, FK constraints, and any tenant-scoped unique key.
+- Use **`l.id`** when logging, emitting `AgentEvent` for the UI, rendering the system prompt, building filesystem paths, setting the key context (`WithAgentKey`), and doing router lookups.
+
+When in doubt, walk the four-step checklist in section 4.
