- Updated logging in `search-server.ts` to use `silentDebug` for non-critical messages, reducing console noise.
- Added a health check endpoint in `worker-service.ts` to improve service monitoring.
- Modified the worker service startup process to start the HTTP server immediately and perform slow initialization in the background.
- Refactored database initialization in `Database.ts` to use the correct `Database` class.
- Implemented a port availability check in `context-hook.ts` to ensure the worker service is ready before making requests.
The dual stderr/stdout pattern was breaking context injection in Claude Code sessions.
Claude Code expects clean JSON on stdout only. Stderr output was interfering with
JSON parsing, causing context to fail loading even though the hook worked from CLI.
Changes:
- Remove process.stderr.write() when running as hook
- Add --colors flag support (matching main branch behavior)
- Output only JSON to stdout for hook execution
- Keep formatted output for manual terminal runs (TTY or --colors)

Architecture transformation: Hooks → HTTP → Worker → Database
**context-hook.ts** (843 → 104 lines, 88% reduction)
- Remove all database imports and raw SQL queries
- HTTP GET to /api/context/inject
- Returns both formatted (stderr) and unformatted (stdout) context
- Dual output: colored display for users, plain text for model
**user-message-hook.ts** (updated, 113 lines)
- HTTP GET to /api/context/inject with colors=true
- Displays formatted context to users via stderr
- No database dependencies
**save-hook.ts** (418 → 99 lines, 76% reduction)
- Remove all SessionStore database methods
- HTTP POST to /api/sessions/observations
- Worker handles privacy checks and observation creation
- Fire-and-forget pattern with 2s timeout
**summary-hook.ts** (435 → 200 lines, 54% reduction)
- Remove all SessionStore database methods
- Keep local transcript parsing (hook has file access)
- HTTP POST to /api/sessions/summarize
- Worker handles privacy checks and summary generation
**cleanup-hook.ts** (414 → 90 lines, 78% reduction)
- Remove all SessionStore database methods
- HTTP POST to /api/sessions/complete
- Worker handles session completion and DB cleanup
- Non-fatal if worker unavailable
**Benefits:**

- All database operations centralized in worker service
- Simpler, more maintainable hook code
- Complete separation of concerns: I/O vs business logic
* fix: Hide console window on Windows when spawning child processes
Add windowsHide: true to spawnSync and execSync calls to prevent
empty console windows from appearing on Windows when hooks execute.
Fixes two spawn points:
- worker-utils.ts: PM2 spawn when starting worker service
- user-message-hook.ts: Node spawn for context display

* fix: Add windowsHide to remaining execSync calls for complete Windows console window hiding
This completes the Windows console window fix by adding `windowsHide: true` to all remaining `execSync` calls:
- src/services/worker-service.ts:220 - pgrep command for orphaned process detection
- src/services/worker-service.ts:226 - pkill command for process cleanup
- src/services/worker/SDKAgent.ts:414 - where/which claude command for finding executable
These operations are less frequent than the user-prompt hook, but should still avoid spawning console windows on Windows for a complete fix.

* feat: Add dual-tag system for meta-observation control
Implements <private> and <claude-mem-context> tag stripping at hook layer
to give users fine-grained control over what gets persisted in observations
and enable future real-time context injection without recursive storage.
**Features:**
- stripMemoryTags() function in save-hook.ts
- Strips both <private> and <claude-mem-context> tags before sending to worker
- Always active (no configuration needed)
- Comprehensive test suite (19 tests, all passing)
- User documentation for <private> tag
- Technical architecture documentation
**Architecture:**
- Edge processing pattern (filter at hook, not worker)
- Defensive type handling with silentDebug
- Supports multiline, nested, and multiple tags
- Enables strategic orchestration for internal tools
**User-Facing:**
- <private> tag for manual privacy control (documented)
- Prevents sensitive data from persisting in observations
**Infrastructure:**
- <claude-mem-context> tag ready for real-time context feature
- Prevents recursive storage when context injection ships

* fix: Strip private tags from user prompts and skip memory ops for fully private prompts
Fixes critical privacy bug where <private> tags were not being stripped from
user prompts before storage in user_prompts table, making private content
searchable via mem-search.
Changes:
1. new-hook.ts: Skip memory operations for fully private prompts
- If cleaned prompt is empty after stripping tags, skip saveUserPrompt
- Skip worker init to avoid wasting resources on empty prompts
- Logs: "(fully private - skipped)"
2. save-hook.ts: Skip observations for fully private prompts
- Check if user prompt was entirely private before creating observations
- Respects user intent: fully private prompt = no observations at all
- Prevents "thoughts pop up" issue where private prompts create public observations
3. SessionStore.ts: Add getUserPrompt() method
- Retrieves prompt text by session_id and prompt_number
- Used by save-hook to check if prompt was private
4. Tests: Added 4 new tests for fully private prompt detection (16 total, all passing)
5. Docs: Updated private-tags.mdx to reflect correct behavior
- User prompts ARE now filtered before storage
- Private content never reaches database or search indices
Privacy Protection:
- Fully private prompts: No user_prompt saved, no worker init, no observations
- Partially private prompts: Tags stripped, content sanitized before storage
- Zero leaks: Private content never indexed or searchable
Addresses reviewer feedback on PR #153 about user prompt filtering.

Implements three-layer defense against native module version mismatches:
Layer 1: Node.js Version Tracking
- Track Node.js version alongside package version in .install-version marker
- Auto-trigger npm install when Node.js version changes
- Backward compatible with old plain-text version marker format
Layer 2: Native Module Verification
- Add verifyNativeModules() function to test better-sqlite3 loads correctly
- Verify after install completes to catch corrupted builds
- Retry with force flag if initial install verification fails
Layer 3: Graceful Failure
- Catch ERR_DLOPEN_FAILED in context-hook and delete version marker
- Exit cleanly to avoid error spam in Claude Code UI
- Auto-fix on next session start
Changes:
- scripts/smart-install.js: Add Node.js version tracking and verification
- src/hooks/context-hook.ts: Add graceful failure handling for native module errors
- tests/smart-install.test.js: Add tests for version marker format compatibility
- plugin/scripts/context-hook.js: Built output from TypeScript source
Fixes the issue where users see ERR_DLOPEN_FAILED errors after Node.js upgrades,
requiring manual npm install. Now automatically detects and fixes the issue.

**Problem:**
- Sessions created with empty project names couldn't be updated
- INSERT OR IGNORE skipped updates when session already existed
- Context-hook couldn't find observations (WHERE project = 'claude-mem')
- 364 observations had empty project names
**Root Cause:**
createSDKSession() used INSERT OR IGNORE for idempotency, but never
updated project/prompt fields when session already existed. If SAVE hook
created session first (with empty project), NEW hook couldn't fix it.
**Solution:**
When INSERT is ignored (session exists), UPDATE project and user_prompt
if we have non-empty values. This ensures project name gets set even
when session was created by SAVE hook or with incomplete data.
**Impact:**
- New sessions will always have correct project name
- Backfilled 364 historical observations with project='claude-mem'
- Context injection will now work (finds observations by project)

1. **Fixed incorrect discovery token calculation** (src/services/worker/SDKAgent.ts)
- Changed from passing cumulative total to per-response delta
- Now correctly tracks token cost for each observation/summary
- Captures token state before/after response processing
- Prevents all observations getting inflated cumulative values
2. **Fixed schema version mismatch** (src/services/sqlite/SessionStore.ts)
- Changed ensureDiscoveryTokensColumn() from version 11 to version 7
- Now matches migration007 definition in migrations.ts
- Ensures consistent version tracking across migration system
These fixes ensure ROI metrics accurately reflect token costs.

- Removed concept-based filtering and icon selection
- Simplified progressive disclosure instructions to reference types instead of concepts
- All observations now shown in timeline (no concept filtering)
Technical details:
- Modified: src/hooks/context-hook.ts:203-207 (legend)
- Modified: src/hooks/context-hook.ts:210-223 (progressive disclosure text)
