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).

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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.

Tighten platform source persistence so legacy callers cannot silently relabel existing sessions, repair migration 24 when schema_versions drifts from the real schema, and polish the follow-up UI/error-handler review nits.
- only backfill platform_source when it is blank and raise on explicit source conflicts for an existing session
- make migration 24 verify both the sdk_sessions column and its index before treating it as applied
- expose platform_source from the functional session getters and add regression tests for source preservation and schema drift recovery
- add the required APPROVED OVERRIDE annotation for centralized HTTP error translation
- keep mobile source pills on a single horizontal row
Persist platform_source across session creation, transcript ingestion, API query paths, and viewer state so Claude and Codex data can coexist without bleeding into each other.
- add platform-source normalization helpers and persist platform_source in sdk_sessions via migration 24 with backfill and indexing
- thread platformSource through CLI hooks, transcript processing, context generation, pagination, search routes, SSE payloads, and session management
- expose source-aware project catalogs, viewer tabs, context preview selectors, and source badges for observations, prompts, and summaries
- start the transcript watcher from the worker for transcript-based clients and preserve platform source during Codex ingestion
- auto-start the worker from the MCP server for MCP-only clients and tighten stdio-driven cleanup during shutdown
- keep createSDKSession backward compatible with existing custom-title callers while allowing explicit platform source forwarding
GeminiAgent sends the full conversation history with every API call,
causing quadratic token growth per session. A 100-observation session
sends ~30M cumulative input tokens. This ports the proven truncateHistory()
sliding window from OpenRouterAgent to GeminiAgent.
- Add CLAUDE_MEM_GEMINI_MAX_CONTEXT_MESSAGES (default: 20) and
CLAUDE_MEM_GEMINI_MAX_TOKENS (default: 100000) settings
- Add truncateHistory() to GeminiAgent using shared estimateTokens()
- Always preserve at least the newest message to avoid empty API requests
- Add settings validation in SettingsRoutes (1-100 messages, 1K-1M tokens)
- Add regression tests for truncation and oversized single-prompt edge case

* fix: stop spinner from spinning forever due to orphaned DB messages
The activity spinner never stopped because isAnySessionProcessing() queried
ALL pending/processing messages in the database, including orphaned messages
from dead sessions that no generator would ever process.
Root cause: isAnySessionProcessing() used hasAnyPendingWork() which is a
global DB scan. Changed it to use getTotalQueueDepth() which only checks
sessions in the active in-memory Map.
Additional fixes:
- Add terminateSession() to enforce restart-or-terminate invariant
- Fix 3 zombie paths in .finally() handler that left sessions alive
- Clean up idle sessions from memory on successful completion
- Remove redundant bare isProcessing:true broadcast
- Replace inline require() with proper accessor
- Add 8 regression tests for session termination invariant

- Compute queueDepth once in broadcastProcessingStatus() and derive
isProcessing from it, eliminating redundant double iteration

Add a PreToolUse gate that blocks file reads on first attempt when rich
observation history exists, presenting the timeline as feedback. Claude

- POST /api/file-context/gate endpoint in worker
- stderrMessage plumbing in hook-command for exit code 2

- Use getProjectContext(cwd).allProjects for project scoping (same as SessionStart)

* fix: revert Unix domain socket transport, restore TCP on port 37777

The chroma-mcp CLI defaults to SSL when using --client-type http.
When CLAUDE_MEM_CHROMA_SSL is false (the common case for local

The pending-work-restart logic had no retry limit, causing infinite loops
when sessions encountered FOREIGN KEY constraint failures. This led to
2000+ error log entries per minute and eventual worker crash via SIGTERM.
Two fixes:
1. Add 'FOREIGN KEY constraint failed' to unrecoverable error patterns
so it short-circuits immediately instead of falling through to restart
2. Add MAX_PENDING_RESTARTS (3) limit to pending-work-restart path as a
safety net for any future unhandled persistent errors

storeObservations() and storeObservationsAndMarkComplete() were missing
the content-hash deduplication that storeObservation() (singular) already
had via computeObservationContentHash() and findDuplicateObservation().
This caused the Gemini provider (and potentially others that return
multiple observations per response) to insert 2-10x duplicate rows per
tool use, since the batch methods inserted unconditionally without
checking content_hash.
The fix adds the same dedup pattern from storeObservation() to both
batch methods:
1. Compute content hash via computeObservationContentHash()
2. Check for existing observation within 30s window via findDuplicateObservation()
3. Skip insert and reuse existing ID if duplicate found
4. Include content_hash column in INSERT statement
Fixes#1158 (duplicate observations with Gemini provider)

When a claude-mem DB is synced between machines running different versions,
orphaned indexes can reference non-existent columns (e.g. idx_observations_content_hash
referencing content_hash). This causes SQLite to throw "malformed database schema"
on ALL queries, including PRAGMAs, creating a silent 503 failure loop.
The fix detects this on startup, uses Python's sqlite3 module to drop the
orphaned schema objects (bun:sqlite doesn't support writable_schema modifications),
resets migration versions, and lets the idempotent migration system recreate
everything properly.

When a search query includes dateStart/dateEnd parameters, the Chroma
semantic search path (PATH 2) ignored them entirely and only applied a
hardcoded 90-day recency window. This meant date-filtered searches
returned results from outside the requested range.
Now the Chroma path checks for a user-provided dateRange first. If
present, it filters results by the requested start/end bounds. The
90-day window is only used as the default when no date filter is
specified, preserving backward compatibility.

longer read by ContextConfigLoader since all modes now use their mode
definition. Removes the constants, defaults, UI controls, and the
now-empty observation-metadata.ts file.

* feat: add smart-file-read module for token-optimized semantic code search
- Created package.json for the smart-file-read module with dependencies and scripts.
- Implemented parser.ts for code structure parsing using tree-sitter, supporting multiple languages.
- Developed search.ts for searching code files and symbols with grep-style and structural matching.
- Added test-run.mjs for testing search and outline functionalities.
- Configured TypeScript with tsconfig.json for strict type checking and module resolution.
* fix: update .gitignore to include _tree-sitter and remove unused subproject
* feat: add preliminary results and skill recommendation for smart-explore module
* chore: remove outdated plan.md file detailing session start hook issues
* feat: update Smart File Read integration plan and skill documentation for smart-explore
* feat: migrate Smart File Read to web-tree-sitter WASM for cross-platform compatibility
* refactor: switch to tree-sitter CLI for parsing and enhance search functionality
- Updated `parser.ts` to utilize the tree-sitter CLI for AST extraction instead of native bindings, improving compatibility and performance.
- Removed grammar loading logic and replaced it with a path resolution for grammar packages.
- Implemented batch parsing in `parseFilesBatch` to handle multiple files in a single CLI call, enhancing search speed.
- Refactored `searchCodebase` to collect files and parse them in batches, streamlining the search process.
- Adjusted symbol extraction logic to accommodate the new parsing method and ensure accurate symbol matching.
* feat: update Smart File Read integration plan to utilize tree-sitter CLI for improved performance and cross-platform compatibility
* feat: add smart-file-read parser and search to src/services
Copy validated tree-sitter CLI-based parser and search modules from
smart-file-read prototype into the claude-mem source tree for MCP
tool integration.

* feat: register smart_search, smart_unfold, smart_outline MCP tools
Add 3 tree-sitter AST-based code exploration tools to the MCP server.
Direct execution (no HTTP delegation) — they call parser/search
functions directly for sub-second response times.

* feat: add tree-sitter CLI deps to build system and plugin runtime
Externalize tree-sitter packages in esbuild MCP server build. Add
10 grammar packages + CLI to plugin package.json for runtime install.
Remove unused @chroma-core/default-embed from plugin deps.

* Add comprehensive documentation for the smart-explore feature
- Introduced a detailed technical reference covering the architecture, parser, search engine, and tool registration for the smart-explore feature in claude-mem.
- Documented the three-layer workflow: search, outline, and unfold, along with their respective MCP tools.
- Explained the parsing process using tree-sitter, including language support, query patterns, and symbol extraction.
- Outlined the search module's functionality, including file discovery, batch parsing, and relevance scoring.
- Provided insights into build system integration and token economics for efficient code exploration.
* chore: remove experiment artifacts, prototypes, and plan files
Remove A/B test docs, prototype smart-file-read directory, and
implementation plans. Keep only production code.

* refactor: simplify hooks configuration and remove setup script
* fix: use execFileSync to prevent command injection in tree-sitter parser
Replaces execSync shell string with execFileSync + argument array,
eliminating shell interpretation of file paths. Also corrects
file_pattern description from "Glob pattern" to "Substring filter".

* fix: resolve PostToolUse hook crashes and 5s latency (#1220)
Three compounding bugs caused hook failures:
1. Missing break statements in worker-service.ts switch — if async
code threw before process.exit(), execution fell through to
subsequent cases. Added break to all 7 cases missing them.
2. Unhandled promise rejection on main() — added .catch() that logs
the error and exits 0 (per project exit code strategy: don't block
Claude Code or leave Windows Terminal tabs open).
3. Redundant start commands in hooks.json — PostToolUse,
UserPromptSubmit, and Stop groups each had a standalone start
command that was redundant (the hook case already calls
ensureWorkerStarted internally). The redundant start also caused
5s latency via bun-runner.js collectStdin() timeout since Claude
Code never closes stdin.

* fix: add CLAUDE_PLUGIN_ROOT fallback for Stop hooks (#1215)
Upstream Claude Code bug (anthropics/claude-code#24529) leaves
CLAUDE_PLUGIN_ROOT unset for Stop hooks on macOS and ALL hooks
on Linux. Two-layer defense:
1. Shell-level: hooks.json commands now use inline fallback
_R="${CLAUDE_PLUGIN_ROOT}"; [ -z "$_R" ] && _R="$HOME/...";
falling back to the known marketplace install path.
2. Script-level: bun-runner.js self-resolves plugin root from
its own filesystem location via import.meta.url, and fixes
broken /scripts/... paths that result from empty expansion.
Added test to verify all hook commands include the fallback path.
