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)

The /api/context/inject endpoint was using an incorrect relative import
path for context-generator.cjs. Since SearchRoutes is in
src/services/worker/http/routes/, the correct path to reach
src/services/context-generator.ts is ../../../context-generator.js
This fixes the session start context injection issue where the hook
would print correctly but no context would load in the session.

Major architectural improvements to the worker service:
- Extracted monolithic WorkerService (~1900 lines) into organized route classes
- New HTTP layer with dedicated route handlers:
- SessionRoutes: Session lifecycle operations
- DataRoutes: Data retrieval endpoints
- SearchRoutes: Search/MCP proxy operations
- SettingsRoutes: Settings and configuration
- ViewerRoutes: Health, UI, and SSE streaming
- Added comprehensive README documenting worker architecture
- Improved build script to handle worker service compilation
- Added context-generator for hook context operations
This is Phase 1 of worker refactoring - pure code reorganization with zero
functional changes. All existing behavior preserved while improving
maintainability and code organization.

- Created session summary tests to validate summary generation from conversation context upon session pause or stop.
- Developed integration tests to cover the full observation lifecycle, including context injection, observation queuing, and error recovery.
- Introduced reusable mock factories and scenarios for consistent testing across different test files.
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)

- Add /api/sessions/summarize endpoint (handles summaries by claudeSessionId)
- Add /api/sessions/complete endpoint (handles cleanup by claudeSessionId)
- Import stripMemoryTagsFromJson for privacy tag handling
- All endpoints accept claudeSessionId in request body (not path params)
- Enables hooks to become pure HTTP clients with zero database dependencies
- Port context-generator.ts service (719 lines)
- Extracts all context generation logic from context-hook
- Supports formatted (ANSI colors) and unformatted output
- Uses better-sqlite3 via SessionStore (no Bun-specific code)
- Enables context generation via worker HTTP API
* 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
Reference: https://nodejs.org/api/child_process.html (windowsHide option)

* 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.

Restores observation skip guidance that was removed in commit 68290a9
for token reduction. The removal caused the observer agent to forget
skip criteria after the first prompt, leading to more verbose
observations of routine operations.
Changes:
- Added WHEN TO SKIP section back to buildContinuationPrompt
- Added condensed CRITICAL reminder about what to record
- Maintains token efficiency by using condensed guidance vs full examples
This balances token usage with observation quality by keeping the
essential skip criteria without the full WHAT TO RECORD examples.

* 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.

Fixes a SyntaxError where an extra closing brace on line 392 was causing
"Missing catch or finally after try" error. The PM2 worker startup
try/catch block was properly formed but had an orphaned closing brace
that didn't match any opening brace.
This was breaking the SessionStart hook and preventing the plugin from
loading correctly.

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.
