Two bugs fixed:
1. SessionCompletionHandler called dbManager.getSessionStore() during
WorkerService construction, before DB initialization. Changed to
accept DatabaseManager and defer the call to runtime.
2. migration009 (generated_by_model, relevance_count columns) only ran
via the deprecated MigrationRunner path, never through SessionStore's
migration chain. Added addObservationModelColumns() to SessionStore
constructor. Checks column existence directly since schema_versions
may have been marked applied without the ALTER TABLE succeeding.
Also removed duplicate transcriptWatcher declaration and shutdown block
(merge artifact).

Number(x) || 10 converts 0 to 10 since 0 is falsy, making it impossible
to request zero context depth (anchor only). Replace with explicit null

- tests/servers/mcp-tool-schemas.test.ts: remove `import '../../src/servers/mcp-server.js'`
which triggered server startup side effects; test only needs to read the TS source as text
- src/services/worker/SearchManager.ts: add Number() coercion for depth_before/depth_after
in timeline(), getContextTimeline(), getTimelineByQuery() — HTTP query strings deliver
these as strings, coercion ensures they are always numbers before being passed to
filterByDepth() and getTimelineAround*()

- Sort within-day observations chronologically (was specificity-ordered)
- Canonicalize relative paths to POSIX format before DB lookup
- Skip projects param when allProjects is empty (prevents cross-project leaks)
- Remove dead stderrMessage field and hook-command block (unused after permissionDecision switch)
- Type permissionDecision as 'allow' | 'deny' union instead of string
- Remove redundant non-null assertions in getObservationsByFilePath
- Add edit guidance to deny message (use sed via Bash with smart tools)

The per-session FileReadGate was never requested and broke the cost
savings loop — subsequent reads in the same session silently bypassed
the timeline, hiding newly created observations.
Now the timeline fires on every read that has observations, using the
hook contract's permissionDecision: "deny" with the timeline as the
reason (exit 0 + JSON) instead of exit code 2 + stderr.
- Delete FileReadGate.ts entirely
- Remove /api/file-context/gate endpoint from DataRoutes
- Switch handler from exit code 2 to permissionDecision: "deny"
- Restore permissionDecision fields to HookResult
- Eliminate one HTTP round-trip per read (no gate check needed)

- Use exact path equality in deduplicateObservations instead of substring includes
- Scope FileReadGate by session+cwd to prevent worktree collisions
- Refresh lastAccess TTL on active sessions; throttle prune to every 50 calls

- Fetch 40 candidates, dedup/score down to 15 for display
- Reduce default by-file query limit from 30 to 15

The compiled binary (v10.6.3) creates these columns at runtime via
MigrationRunner, but no corresponding migration exists in the TypeScript
source. Anyone building from source gets observations without these
columns, breaking the feedback pipeline and model tracking.
This migration conditionally adds both columns using PRAGMA table_info
checks, making it safe for databases that already have them.

PHP was listed as a supported language in CHANGELOG and .php files were
scanned by search.ts, but parser.ts was missing:
- .php extension in LANG_MAP (causing detectLanguage to return 'unknown')
- 'php' entry in GRAMMAR_PACKAGES (no grammar path to resolve)
- PHP query patterns for symbol extraction
- PHP case in getQueryKey()
This meant smart_search/smart_outline/smart_unfold scanned PHP files
but extracted 0 symbols because the grammar could not be resolved.
Changes:
- Add '.php' -> 'php' to LANG_MAP
- Add 'php' -> 'tree-sitter-php/php' to GRAMMAR_PACKAGES
- Add PHP tree-sitter query patterns (functions, methods, classes, interfaces, traits, use statements)
- Add 'php' case to getQueryKey()
- Add tree-sitter-php ^0.24.2 to devDependencies
On Bun/Windows, `require.main !== module` in CJS mode causes the worker
to exit silently with code 0. The wrapper already sets CLAUDE_MEM_MANAGED=true
when spawning the inner worker, so checking this env var is a safe fallback
that doesn't affect standalone execution.
Ref #1450 (incomplete fix in PR #1518 — ESM path fixed but CJS branch not).

The generated_by_model column was added to the observations table in the
Phase 0 governance schema migration but never wired into the INSERT
statements. All 3,878+ observations in production have this field NULL.
This fix threads the model ID from each agent (SDKAgent, GeminiAgent,
OpenRouterAgent) through processAgentResponse() into storeObservation(),
storeObservations(), and storeObservationsAndMarkComplete().
Unblocks Thompson Sampling RFC (#1571) which needs {obs_type}:{model}
as the bandit arm key.

Critical:
- migrations: change version 8 → 25 to avoid collision with
MigrationRunner.addObservationHierarchicalFields (uses version 8)
- SessionRoutes: remove duplicate imports that prevent compilation
Major:
- SessionRoutes: call applyTierRouting() before every generator spawn
(stale-recovery and crash-recovery paths were missing it)
- applyTierRouting: clear session.modelOverride at top before re-evaluating
to prevent stale tier from persisting across spawns
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Tier Routing:
- Inspect pending queue before starting generator
- Summarize messages → CLAUDE_MEM_TIER_SUMMARY_MODEL (e.g., Opus)
- All simple tools (Read, Glob, Grep, LS) → CLAUDE_MEM_TIER_SIMPLE_MODEL (Haiku)
- Mixed/complex → default model (no override)
- session.modelOverride in ActiveSession, used by SDKAgent.getModelId()
- peekPendingTypes() in PendingMessageStore for non-claiming inspection
- Configurable via CLAUDE_MEM_TIER_ROUTING_ENABLED (default: true)
Feedback Collection (schema only):
- New observation_feedback table via MigrationRunner (schema version 24)
- Tracks signal_type (semantic_inject_hit, search_accessed, etc.)
- Indexes on observation_id and signal_type
- Foundation for future Thompson Sampling optimization
Production data (24h tier routing test):
- 36 Haiku observations in 4 min, quality indistinguishable from Sonnet
- Estimated ~52% cost reduction on SDK Agent usage
- 835 → 6,695 feedback signals collected over 13 days

* feat: semantic context injection via Chroma on every UserPromptSubmit
On each prompt, queries ChromaDB for the top-N most relevant past
observations and injects them as additionalContext. Replaces the
recency-based "last N observations" approach with relevance-based
semantic search.
Changes:
- session-init.ts: After session init, query /api/context/semantic
with user's prompt text. If results found, return as
hookSpecificOutput with hookEventName 'UserPromptSubmit'.
- SearchRoutes.ts: New GET /api/context/semantic endpoint that queries
SearchManager with format='json' and formats results as markdown.
- SettingsDefaultsManager.ts: New settings CLAUDE_MEM_SEMANTIC_INJECT
(default: true) and CLAUDE_MEM_SEMANTIC_INJECT_LIMIT (default: 5).
Key behaviors:
- Fires on every UserPromptSubmit (not just SessionStart)
- Minimum prompt length: 20 chars (skips "ok", "yes", etc.)
- Skips media-only prompts
- Graceful degradation: if worker/Chroma unavailable, no injection
- Survives /clear: re-injects on next prompt (not session-bound)
- Uses workerHttpRequest (v10.6.3 API, not raw fetch)
Production data (23 days, 3,400+ observations):
- Before: 8 most recent observations (often irrelevant to current topic)
- After: 5 most relevant observations (semantic match)
- Token cost: ~1800 → ~800-1200 per injection
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: address CodeRabbit review on PR #1568
- session-init: don't skip semantic injection when contextInjected=true
(only skip agent re-init, semantic lookup must run every prompt)
- session-init: normalize SEMANTIC_INJECT toggle via String().toLowerCase()
- semantic endpoint: change from GET to POST to avoid URL-length limits
and prompt exposure in access logs. Handler accepts both body and query
for backwards compatibility.

* fix: resolve 3 upstream bugs in summarize, ChromaSync, and HealthMonitor
1. summarize.ts: Skip summary when transcript has no assistant message.
Prevents error loop where empty transcripts cause repeated failed
summarize attempts (~30 errors/day observed in production).
2. ChromaSync.ts: Fallback to chroma_update_documents when add fails
with "IDs already exist". Handles partial writes after MCP timeout
without waiting for next backfill cycle.
3. HealthMonitor.ts: Replace HTTP-based isPortInUse with atomic socket
bind on Unix. Eliminates TOCTOU race when two sessions start
simultaneously (HTTP check is non-atomic — both see "port free"
before either completes listen()). Updated tests accordingly.
All three bugs are pre-existing in v10.5.5. Confirmed via log analysis
of 543K lines over 17 days of production usage across two servers.

* feat: drain orphaned pending messages on session completion (SIGTERM)
When deleteSession() aborts the SDK agent via SIGTERM, pending messages
in the queue are never processed. Without drain, they remain in
'pending' status forever — no future generator picks them up because
the session is already completed.
Adds markAllSessionMessagesAbandoned() call after deleteSession() in
completeByDbId(). This reuses the existing PendingMessageStore method
already used by worker-service.ts terminateSession().
Production evidence: 15 orphaned summarize messages found across
completed sessions (ages 3h to 3 days) before this fix. After fix:
0 orphaned messages over 23 days of operation.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: document best-effort drain limitation per CodeRabbit review #1567
Add comment noting the rare race condition when generators outlive the
30s SIGTERM timeout. Practical risk is negligible (0 orphans over 23 days).

SessionEnd has a 1.5s hardcoded cap from Claude Code (CLAUDE_CODE_SESSIONEND_HOOKS_TIMEOUT_MS),
making it unsuitable for waiting on async work. Previously, the Stop hook would fire-and-forget
the summarize request, then SessionEnd would immediately call deleteSession — aborting the SDK
agent mid-summary.
Now the Stop hook (120s timeout, no cap) owns the full lifecycle:
1. Queue summarize request
2. Poll new GET /api/sessions/status endpoint until queue drains
3. Call /api/sessions/complete after summary finishes
SessionEnd is now a true fire-and-forget fallback (process.exit(0) immediately).

Three independent fixes for worker daemon instability:
1. Remove version mismatch auto-restart from ensureWorkerStarted() (#1435).
The marketplace bundle ships with __DEFAULT_PACKAGE_VERSION__ unbaked,
causing BUILT_IN_VERSION to fall back to "development". This creates a
100% reproducible mismatch on every hook call, killing a healthy worker
and often failing to restart. Same pattern across #566, #665, #667,
#669, #689, #1124, #1145 (8+ releases).
2. Add process.ppid and PID-file PID to aggressiveStartupCleanup()
exclusions (#1426). Without this, a newly spawned daemon SIGKILLs
the hook process that spawned it and any already-running worker
the PID file points to.
3. Increase POST_SPAWN_WAIT from 5s to 15s (#1423). The 5s timeout was
sized for Linux (<1s startup) but macOS ARM64 cold starts take 6-8s
with Chroma enabled.

1. Fix esbuild inlining build-machine __dirname as string literal — use
CJS-compatible runtime banner with require("node:url").fileURLToPath
across worker-service, mcp-server, and context-generator builds.
2. Fix isMainModule check missing .cjs extension and Windows backslash
path normalization.
3. Wrap extractLastMessage in try-catch to prevent infinite Stop hook
feedback loop on malformed transcripts (exit 0 instead of exit 2).
4. Replace heavy SessionEnd hook (Node→Bun→1.7MB CJS→HTTP) with
lightweight inline node -e one-liner (~200ms vs >1s).
5. Add 7 Gemini/OpenRouter error patterns to unrecoverablePatterns
circuit breaker to prevent 77K+ retry loops on expired API keys.
6. Preserve CLAUDE_CODE_OAUTH_TOKEN and CLAUDE_CODE_GIT_BASH_PATH in
sanitizeEnv instead of stripping them with the CLAUDE_CODE_ prefix.
7. Use PowerShell -EncodedCommand for spawnDaemon to fix path quoting
when Windows usernames contain spaces.
