* chore: bump version to 7.3.6 in package.json
* Enhance worker readiness checks and MCP connection handling
- Updated health check endpoint to /api/readiness for better initialization tracking.
- Increased timeout for health checks and worker startup retries, especially for Windows.
- Added initialization flags to track MCP readiness and overall worker initialization status.
- Implemented a timeout guard for MCP connection to prevent hanging.
- Adjusted logging to reflect readiness state and errors more accurately.
* fix(windows): use Bun PATH detection in worker wrapper
Phase 2/8: Fix Bun PATH Detection in Worker Wrapper
- Import getBunPath() in worker-wrapper.ts for Bun detection
- Add Bun path resolution before spawning inner worker process
- Update spawn call to use detected Bun path instead of process.execPath
- Add logging to bun-path.ts when PATH detection succeeds
- Add logging when fallback paths are used
- Add Windows-specific validation for .exe extension
- Log warning with searched paths when Bun not found
- Fail fast with clear error message if Bun cannot be detected
This ensures worker-wrapper uses the correct Bun executable on Windows
even when Bun is not in PATH, fixing issue #371 where users reported
"Bun not in PATH" errors despite Bun being installed.

* security: add PID validation and improve ChromaSync timeout handling
Address critical security and reliability issues identified in PR review:
**Security Fixes:**
- Add PID validation before all PowerShell/taskkill command execution
- Validate PIDs are positive integers to prevent command injection
- Apply validation in worker-wrapper.ts, worker-service.ts, and ChromaSync.ts
**Reliability Improvements:**
- Add timeout handling to ChromaSync client.close() (10s timeout)
- Add timeout handling to ChromaSync transport.close() (5s timeout)
- Implement force-kill fallback when ChromaSync close operations timeout
- Prevents hanging on shutdown and ensures subprocess cleanup
**Implementation Details:**
- PID validation checks: Number.isInteger(pid) && pid > 0
- Applied before all execSync taskkill calls on Windows
- Applied in process enumeration (Get-CimInstance) PowerShell commands
- ChromaSync.close() uses Promise.race for timeout enforcement
- Graceful degradation with force-kill fallback on timeout

- Updated response logging to process both empty and non-empty responses.
- Added functionality to mark messages as processed even when the response is empty.
- Refactored message processing logic to ensure all pending messages are marked as processed after successful observation/summary storage.
- Introduced a new private method `markMessagesProcessed` to encapsulate the logic for marking messages as processed, preventing message loss and duplicate processing.
On Windows, Bun doesn't properly release socket handles when the worker
process exits, causing "zombie ports" that remain bound even after all
processes are dead. This required a system reboot to clear.
Solution: Introduce a wrapper process (worker-wrapper.cjs) that:
- Spawns the actual worker as a child with IPC channel
- On restart/shutdown, uses `taskkill /T /F` to kill the entire process tree
- Exits itself, allowing hooks to start fresh
The wrapper has no sockets, so Bun's socket cleanup bug doesn't affect it.
When the wrapper kills the inner worker tree and exits, the port is properly
released and can be immediately reused.
Key changes:
- New worker-wrapper.ts for Windows process lifecycle management
- ProcessManager starts wrapper on Windows, worker directly on Unix
- Worker sends IPC messages to wrapper for restart/shutdown
- Health endpoint now includes debug info (build ID, managed status, hasIpc)
Tested: Restart API now properly releases port and new worker binds to same port.

- All paths (bunPath, script, MARKETPLACE_ROOT) are application-controlled
- Not user input - derived from system paths and installation directories
- If attacker could modify these, they already have filesystem access
- This includes direct access to ~/.claude-mem/claude-mem.db
- Nevertheless, proper escaping follows security best practices

Fixes blank console windows appearing on Windows 11 when spawning the worker process.
## Problem
On Windows, `windowsHide: true` doesn't work when combined with `detached: true` in child_process.spawn().
This is a Node.js limitation (nodejs/node#21825) that **Bun also inherits** because Bun uses Node.js process spawning semantics.
Result: Blank console windows with "claude" title appear during claude-mem operations.
## Solution
Use PowerShell's `Start-Process -WindowStyle Hidden` on Windows to properly hide console windows.
Unix platforms continue using standard `spawn()` with `detached: true`.
## Testing
Validated by ToxMox on Windows 11 in PR #315:
- windowsHide approach: ❌ Still shows blank consoles
- PowerShell approach: ✅ Properly hides windows
## Implementation
```typescript
// Windows: PowerShell workaround
Start-Process -FilePath 'bun' -ArgumentList '${script}' -WindowStyle Hidden
// Unix: Standard spawn (works fine)
spawn(bunPath, [script], { detached: true })
```
## Notes
- Affects BOTH Bun and Node.js runtimes on Windows
- This is a **high-priority fix** for Windows users
- Keeps Bun runtime (doesn't address zombie socket issue)
- Zombie socket issue is separate and requires different solution

* fix: add npm fallback when bun install fails with alias packages
Bun has issues resolving npm alias packages (e.g., string-width-cjs,
strip-ansi-cjs, wrap-ansi-cjs) that are defined in package-lock.json.
When bun fails with 404 errors for these packages, we now fall back
to npm which handles aliases correctly.
This fixes the installation failure that many users are experiencing
where bun install fails with:
error: GET https://registry.npmjs.org/string-width-cjs/-/string-width-cjs-4.2.3.tgz - 404
The fallback is transparent to users - they will see a warning message
and the installation will continue with npm.
Fixes#262

Critical improvement for seamless upgrades across all versions.
Changes:
1. Added /api/version endpoint to worker service
- Returns current worker version from package.json
2. Added version checking in worker-utils.ts
- getPluginVersion() - reads plugin's package.json version
- getWorkerVersion() - fetches version from worker API
- ensureWorkerVersionMatches() - compares and restarts if needed
3. Modified ensureWorkerRunning()
- Now calls ensureWorkerVersionMatches() after health check
- Automatically restarts worker when version mismatch detected
- Logs version mismatch for debugging
Impact:
- Users no longer need to manually restart worker after upgrades
- Eliminates connection errors from running old worker code
- Critical for v7.1.1 (Bun auto-install) and all future releases
- Fixes the issue where PR #236 changes weren't applied until manual restart
Testing:
- Version endpoint working: returns {"version":"7.1.0"}
- Worker health check: passing
- Auto-restart logic: triggers on version mismatch

CRITICAL FIX: v7.1.0 Bun auto-install broken on Windows 11
Problem:
- hooks.json calls `bun smart-install.js` but if Bun isn't installed,
command fails immediately with "bun is not recognized"
- smart-install.js never runs, so Bun never gets installed
- Chicken-and-egg problem
Root Cause:
- v7.1.0 removed Bun/uv auto-installation logic from smart-install.js
- Assumed Bun would already be available
- Breaks fresh installations on all platforms
Solution:
1. Changed SessionStart hook to use `node` for smart-install.js
(Node.js always available in Claude Code)
2. Restored Bun auto-installation logic:
- isBunInstalled() - check if Bun is in PATH
- installBun() - auto-install via PowerShell (Windows) or curl (Unix/macOS)
- Also restored uv auto-installation for Chroma
After Fix:
- smart-install.js runs with node (always available)
- Detects if Bun is missing and auto-installs it
- Subsequent hooks use bun successfully
- Works on fresh Windows installations
Fixes: User report from Discord - Windows 11 'bun' is not recognized

Previously skipped Windows PM2 cleanup based on assumption that PM2
wasn't used on Windows. However, this left potential orphaned processes.
Changes:
- Remove platform check (process.platform !== 'win32')
- Run PM2 cleanup on Mac/Linux/Windows consistently
- Create .pm2-migrated marker on all platforms
- Update documentation to reflect cross-platform behavior
Rationale:
- Quality migration should clean up ALL orphaned processes
- Error handling (try/catch) already makes this safe
- Even if PM2 had Windows issues, cleanup won't hurt
- Consistent behavior across platforms is better UX
Impact:
- Windows users will get PM2 cleanup on first hook trigger
- Marker file now created on Windows (prevents repeated attempts)
- No breaking changes (errors caught and ignored)

- Removed deprecated silentDebug function and replaced its usage with logger.debug.
- Updated tests to use dynamic worker port retrieval instead of hardcoded values.
- Introduced `/api/admin/restart` and `/api/admin/shutdown` endpoints in WorkerService for restarting and shutting down the service.
- Updated error message in hook-error-handler to provide clearer instructions for restarting the worker.
- Refactored worker-utils to remove PM2 dependency and implement ProcessManager for starting the worker service.
- Cleaned up legacy PM2 references and provided new manual start instructions.
- Updated build-hooks.js to remove better-sqlite3 dependency and use bun:sqlite.
- Modified smart-install.js to eliminate checks and installations related to better-sqlite3.
- Refactored Database.ts, SessionSearch.ts, SessionStore.ts, and migrations.ts to import and utilize bun:sqlite.
- Replaced exec and pragma calls with appropriate run methods for bun:sqlite compatibility.
- Removed unnecessary native module verification and installation logic for better-sqlite3.
Critical bug fix:
- Pass project filter to getSessionSummariesByIds() and getUserPromptsByIds() in SearchManager
- Previously only observations were filtered by project, sessions and prompts leaked from other projects
Documentation improvements:
- Update "FTS5 search" to "hybrid search" (accurate terminology)
- Add privacy warning about sensitive data in exports
- Document --project parameter for filtered exports
- Add "Export by Project" examples to advanced usage
Verified with test export using --project=claude-mem filter.

* Fix critical session persistence bug in new-hook
Restores the second POST call to /sessions/:sessionDbId/init that was
incorrectly removed as "duplicate" in the hooks refactor.
The two POST calls serve different purposes:
- POST /api/sessions/init: Creates DB session, saves prompt (no SDK agent)
- POST /sessions/:sessionDbId/init: Starts the SDK agent session
Without the second call, the SDK agent never started, causing:
- First prompts saved to DB but never processed
- Subsequent prompts queued but no agent running to consume them
- Each new prompt creating orphaned sessions instead of continuing
This fix restores proper session continuation across multiple prompts.
Fixes conversation fragmentation reported in production.
* updated agent-sdk
* Skip meta-observations for session-memory file operations
Added a check to skip meta-observations when file operations (Edit, Write, Read, NotebookEdit) are performed on session-memory files. If the file path includes 'session-memory', a debug log is generated and the response indicates that the observation was skipped.
* refactor: Clean up hook-response and new-hook files
- Removed 'PreCompact' hook type and associated logic from hook-response.ts for improved type safety.
- Deleted extensive architecture comments in new-hook.ts to streamline code readability.
- Simplified debug logging in new-hook.ts to reduce verbosity.
- Enhanced ensureWorkerRunning function in worker-utils.ts with a final health check before throwing errors.
- Added a new documentation file outlining the hooks cleanup process and future improvements.
* Refactor cleanup and user message hooks
- Updated cleanup-hook.js to improve error handling and remove unnecessary input checks.
- Simplified user-message-hook.js by removing time-sensitive announcements and streamlining output.
- Enhanced logging functionality in both hooks for better debugging and clarity.
* Refactor error handling in hooks to use centralized error handler
- Introduced `handleWorkerError` function in `src/shared/hook-error-handler.ts` to manage worker-related errors.
- Updated `context-hook.ts`, `new-hook.ts`, `save-hook.ts`, and `summary-hook.ts` to utilize the new error handler, simplifying error management and improving code readability.
- Removed repetitive error handling logic from individual hooks, ensuring consistent user-friendly messages for connection issues.
* Refactor user-message and summary hooks to utilize shared transcript parser; introduce hook exit codes
- Moved user message extraction logic to a new shared module `transcript-parser.ts` for better code reuse.
- Updated `summary-hook.ts` to use the new `extractLastMessage` function for retrieving user and assistant messages.
- Replaced direct exit code usage in `user-message-hook.ts` with constants from `hook-constants.ts` for improved readability and maintainability.
- Added `HOOK_EXIT_CODES` to `hook-constants.ts` to standardize exit codes across hooks.
* Refactor hook input interfaces to enforce required fields
- Updated `SessionStartInput`, `UserPromptSubmitInput`, `PostToolUseInput`, and `StopInput` interfaces to require `session_id`, `transcript_path`, and `cwd` fields, ensuring better type safety and clarity in hook inputs.
- Removed optional index signatures from these interfaces to prevent unintended properties and improve code maintainability.
- Adjusted related hook implementations to align with the new interface definitions.
* Refactor save-hook to remove tool skipping logic; enhance summary-hook to handle spinner stopping with error logging; update SessionRoutes to load skip tools from settings; add CLAUDE_MEM_SKIP_TOOLS to SettingsDefaultsManager for configurable tool exclusion.
* Document CLAUDE_MEM_SKIP_TOOLS setting in public docs
Added documentation for the new CLAUDE_MEM_SKIP_TOOLS configuration
setting in response to PR review feedback. Users can now discover and
customize which tools are excluded from observations.
