* docs: add monolith refactor report with system breakdown
Comprehensive analysis of codebase identifying:
- 14 files over 500 lines requiring refactoring
- 3 critical monoliths (SessionStore, SearchManager, worker-service)
- 80% code duplication across agent files
- 5-phase refactoring roadmap with domain-based architecture
* fix: prevent memory_session_id from equaling content_session_id
The bug: memory_session_id was initialized to contentSessionId as a
"placeholder for FK purposes". This caused the SDK resume logic to
inject memory agent messages into the USER's Claude Code transcript,
corrupting their conversation history.
Root cause:
- SessionStore.createSDKSession initialized memory_session_id = contentSessionId
- SDKAgent checked memorySessionId !== contentSessionId but this check
only worked if the session was fetched fresh from DB
The fix:
- SessionStore: Initialize memory_session_id as NULL, not contentSessionId
- SDKAgent: Simple truthy check !!session.memorySessionId (NULL = fresh start)
- Database migration: Ran UPDATE to set memory_session_id = NULL for 1807
existing sessions that had the bug
Also adds [ALIGNMENT] logging across the session lifecycle to help debug
session continuity issues:
- Hook entry: contentSessionId + promptNumber
- DB lookup: contentSessionId → memorySessionId mapping proof
- Resume decision: shows which memorySessionId will be used for resume
- Capture: logs when memorySessionId is captured from first SDK response
UI: Added "Alignment" quick filter button in LogsModal to show only
alignment logs for debugging session continuity.

* fix: address PR #528 review comments - atomic cleanup and detector improvements
This commit addresses critical review feedback from PR #528:
## 1. Atomic Message Cleanup (Fix Race Condition)
**Problem**: SessionRoutes.ts generator error handler had race condition
- Queried messages then marked failed in loop
- If crash during loop → partial marking → inconsistent state
**Solution**:
- Added `markSessionMessagesFailed()` to PendingMessageStore.ts
- Single atomic UPDATE statement replaces loop
- Follows existing pattern from `resetProcessingToPending()`
**Files**:
- src/services/sqlite/PendingMessageStore.ts (new method)
- src/services/worker/http/routes/SessionRoutes.ts (use new method)
## 2. Anti-Pattern Detector Improvements
**Problem**: Detector didn't recognize logger.failure() method
- Lines 212 & 335 already included "failure"
- Lines 112-113 (PARTIAL_ERROR_LOGGING detection) did not
**Solution**: Updated regex patterns to include "failure" for consistency
**Files**:
- scripts/anti-pattern-test/detect-error-handling-antipatterns.ts
## 3. Documentation
**PR Comment**: Added clarification on memory_session_id fix location
- Points to SessionStore.ts:1155
- Explains why NULL initialization prevents message injection bug

* refactor(sqlite): decompose SessionStore into modular architecture
Extract the 2011-line SessionStore.ts monolith into focused, single-responsibility
modules following grep-optimized progressive disclosure pattern:
New module structure:
- sessions/ - Session creation and retrieval (create.ts, get.ts, types.ts)
- observations/ - Observation storage and queries (store.ts, get.ts, recent.ts, files.ts, types.ts)
- summaries/ - Summary storage and queries (store.ts, get.ts, recent.ts, types.ts)
- prompts/ - User prompt management (store.ts, get.ts, types.ts)
- timeline/ - Cross-entity timeline queries (queries.ts)
- import/ - Bulk import operations (bulk.ts)
- migrations/ - Database migrations (runner.ts)
New coordinator files:
- Database.ts - ClaudeMemDatabase class with re-exports
- transactions.ts - Atomic cross-entity transactions
- Named re-export facades (Sessions.ts, Observations.ts, etc.)
Key design decisions:
- All functions take `db: Database` as first parameter (functional style)
- Named re-exports instead of index.ts for grep-friendliness
- SessionStore retained as backward-compatible wrapper
- Target file size: 50-150 lines (60% compliance)

* fix: distinguish connection errors from collection-not-found in ChromaSync
Previously, ensureCollection() caught ALL errors from chroma_get_collection_info

like "Not connected" to trigger unnecessary collection creation attempts.
Now connection-related errors are re-thrown immediately instead of being
misinterpreted as missing collections.

* fix: improve error handling for Chroma connection and collection creation
* fix: remove dead last_user_message from summarize flow
The last_user_message field was extracted from transcripts but never used.
In Claude Code transcripts, "user" type messages are mostly tool_results,
not actual user input. The user's original request is already stored in
user_prompts table.
This removes the false warning "Missing last_user_message when queueing
summary" which was complaining about missing data that didn't exist and
wasn't needed.
Changes:
- summary-hook: Only extract last_assistant_message
- SessionRoutes: Remove last_user_message from request body handling

* Add enforceable anti-pattern detection for try-catch abuse
PROBLEM:
- Overly-broad try-catch blocks waste 10+ hours of debugging time
- Empty catch blocks silently swallow errors
- AI assistants use try-catch to paper over uncertainty instead of doing research
SOLUTION:
1. Created detect-error-handling-antipatterns.ts test
- Detects empty catch blocks (45 CRITICAL found)
- Detects catch without logging (45 CRITICAL total)
- Detects large try blocks (>10 lines)
- Detects generic catch without type checking
- Detects catch-and-continue on critical paths
- Exit code 1 if critical issues found
2. Updated CLAUDE.md with MANDATORY ERROR HANDLING RULES
- 5-question pre-flight checklist before any try-catch
- FORBIDDEN patterns with examples
- ALLOWED patterns with examples
- Meta-rule: UNCERTAINTY TRIGGERS RESEARCH, NOT TRY-CATCH
- Critical path protection list
3. Created comprehensive try-catch audit report
- Documents all 96 try-catch blocks in worker service
- Identifies critical issue at worker-service.ts:748-750
- Categorizes patterns and provides recommendations
This is enforceable via test, not just instructions that can be ignored.
Current state: 163 anti-patterns detected (45 critical, 47 high, 71 medium)

* fix: add logging to promise catches on critical paths (Wave 2)
Wave 2 of error handling cleanup - fixing empty promise catch handlers
that silently swallow errors on critical code paths. These are the
patterns that caused the 10-hour debugging session.
Fixed empty promise catches:
- worker-service.ts:642 - Background initialization failures
- SDKAgent.ts:372,446 - Session processor errors
- GeminiAgent.ts:408,475 - Finalization failures
- OpenRouterAgent.ts:451,518 - Finalization failures
- SessionManager.ts:289 - Generator promise failures
Added justification comments to catch-and-continue blocks:
- worker-service.ts:68 - PID file removal (cleanup, non-critical)
- worker-service.ts:130 - Cursor context update (non-critical)
All promise rejection handlers now log errors with context, preventing
silent failures that were nearly impossible to debug.
Note: The anti-pattern detector only tracks try-catch blocks, not
standalone promise chains. These fixes address the root cause of the
original 10-hour debugging session even though the detector count
remains unchanged.

* fix: add logging and documentation to error handling patterns (Wave 3)
Wave 3 of error handling cleanup - comprehensive review and fixes for
remaining critical issues identified by the anti-pattern detector.
Changes organized by severity:
**Wave 3.1: Fixed 2 EMPTY_CATCH blocks**
- worker-service.ts:162 - Health check polling now logs failures
- worker-service.ts:610 - Process cleanup logs failures
**Wave 3.2: Reviewed 12 CATCH_AND_CONTINUE patterns**
- Verified all are correct (log errors AND exit/return HTTP errors)
- Added justification comment to session recovery (line 829)
- All patterns properly notify callers of failures
**Wave 3.3: Fixed 29 NO_LOGGING_IN_CATCH issues**
Added logging to 16 catch blocks:
- UI layer: useSettings.ts, useContextPreview.ts (console logging)
- Servers: mcp-server.ts health checks and tool execution
- Worker: version fetch, cleanup, config corruption
- Routes: error handler, session recovery, settings validation
- Services: branch checkout, timeline queries
Documented 13 intentional exceptions with comments explaining why:
- Hot paths (port checks, process checks in tight loops)
- Error accumulation (transcript parser collects for batch retrieval)
- Special cases (logger can't log its own failures)
- Fallback parsing (JSON parse in optional data structures)
All changes follow error handling guidelines from CLAUDE.md:
- Appropriate log levels (error/warn/debug)
- Context objects with relevant details
- Descriptive messages explaining failures
- Error extraction pattern for Error instances
Progress: 41 → 29 detector warnings
Remaining warnings are conservative flags on verified-correct patterns
(catch-and-continue blocks that properly log + notify callers).
Build verified successful. All error handling now provides visibility
for debugging while avoiding excessive logging on hot paths.

Added functionality to clear failed messages from the observation queue:
**Changes:**
- PendingMessageStore: Added clearFailed() method to delete failed messages
- DataRoutes: Added DELETE /api/pending-queue/failed endpoint
- CLI: Created scripts/clear-failed-queue.ts for interactive queue clearing
- package.json: Added npm run queue:clear script
**Usage:**
npm run queue:clear # Interactive - prompts for confirmation
npm run queue:clear -- --force # Non-interactive - clears without prompt
Failed messages are observations that exceeded max retry count. They
remain in the queue for debugging but won't be processed. This command
removes them to clean up the queue.
Works alongside existing queue:check and queue:process commands to
provide complete queue management capabilities.

Skip logging GET /api/logs requests in HTTP middleware to prevent
log spam from auto-refresh polling (every 2s). Keeps the auto-refresh
feature functional while eliminating the repetitive log entries.

* refactor: enhance error handling guidelines with approved overrides for justified exceptions

- Removed unnecessary logging for aborted sessions in WorkerService.
- Simplified the finally block in WorkerService by removing crash recovery logging.
- Cleaned up the try-catch structure in SDKAgent's startSession method, removing redundant error handling.
- Improved logging for session aborts and unexpected exits.
- Introduced a variable to track if the session was aborted for clarity.
- Added logic to create a new AbortController when restarting the generator after a crash.
- Implemented a mechanism to abort the session if there are no pending tasks after a natural completion.
- Ensured that errors during recovery checks lead to session abortion to prevent resource leaks.
* fix: make migration 17 idempotent and standardize column names
Migration 17 renamed columns from sdk_session_id to memory_session_id,
but the migration wasn't fully idempotent - it could fail on databases
in intermediate states. This caused errors like:
- "no such column: sdk_session_id" (when columns already renamed)
- "table observations has no column named memory_session_id" (when not renamed)
Changes:
- Rewrite renameSessionIdColumns() to check each table individually
- Use safeRenameColumn() helper that handles all edge cases gracefully
- Deprecate migration 19 (repair migration) since 17 is now idempotent
- Update maintenance scripts to use memory_session_id column name
- Update test files to use new column names
Fixes column mismatch bug in v8.2.6+
* Merge origin/main into column-mismatch

- Updated `context-inject.sh` to refresh context before prompt submission and ensure worker is running.
- Added functionality to register and unregister projects for automatic context updates in `worker-service.ts`.
- Implemented methods to read and write the cursor project registry, allowing for better management of installed hooks.
- Integrated context updates into the `GeminiAgent`, `OpenRouterAgent`, and `SDKAgent` to ensure the latest context is available during sessions.
This update improves the integration of Claude-Mem with Cursor, ensuring that context is consistently updated and accessible across sessions.
- Introduced functionality for installing, uninstalling, and checking the status of Cursor hooks.
- Added a new command structure for managing hooks with detailed usage instructions.
- Implemented a method to locate the cursor-hooks directory across different environments.
- Updated build-hooks script to inform users about the location of Cursor hooks.
This enhancement streamlines the integration of Claude-Mem with Cursor, improving user experience and accessibility of hooks.
When the plugin updates but the worker was already running on the old version,
hooks would fail with 400 errors because the new hook scripts tried to call
APIs that don't exist in the old worker.
Changes:
- /api/version now returns BUILT_IN_VERSION (compiled at build time) instead
of reading from disk at runtime
- worker-service start command now checks for version mismatch and
auto-restarts if the running worker version differs from plugin version
- Downgraded hook version mismatch warning to debug logging (now handled
by auto-restart)
