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.

* fix: shorten MCP server name to prevent tool name length errors (#358)
Root cause: Claude Code prefixes MCP tool names with
`mcp__plugin_{plugin-name}_{server-name}__` which was 43 chars
for `mcp__plugin_claude-mem_claude-mem-search__`. Combined with
`progressive_description` (22 chars) this exceeded the 64 char limit.
Changes:
- Shortened MCP server name from 'claude-mem-search' to 'mem-search'
(saves 8 chars, new prefix is 35 chars)
- Renamed `progressive_description` tool to `help` (saves 18 chars)
- Updated SKILL.md to reference new `help` tool name
- Updated internal Server constructor name for consistency
All tool names now safely under 64 char limit:
- Longest is now `get_batch_observations` at 56 chars total
- `help` is only 39 chars total

Adds proper PowerShell escaping to prevent theoretical command injection
in Start-Process arguments on Windows.
Security Context:
- 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
Changes:
- Added escapePowerShellString() helper for PowerShell single-quote escaping
- Escapes all path arguments before PowerShell command construction
- Added security context comment explaining threat model

* feat: unify timeline formatting across search and context services
Extract shared timeline formatting utilities into reusable module to align
MCP search output format with context-generator's date/file-grouped format.
Changes:
- Create src/shared/timeline-formatting.ts with reusable utilities
(parseJsonArray, formatDateTime, formatTime, formatDate, toRelativePath,
extractFirstFile, groupByDate)
- Refactor context-generator.ts to use shared utilities
- Update SearchManager.search() to use date/file grouping
- Add search-specific row formatters to FormattingService
- Fix timeline methods to extract actual file paths from metadata
instead of hardcoding 'General'
- Remove Work column from search output (kept in context output)
Result: Consistent date/file-grouped markdown formatting across both
systems while maintaining their different column requirements.

both try and catch scopes.

- Removed all instances of happy_path_error__with_fallback from various hooks, services, and utilities.
- Introduced logger.happyPathError for consistent logging of unexpected nulls and fallback values.
- Updated the logger utility to include a new happyPathError method with enhanced context and stack trace.
- Deprecated silent-debug utility as all logging functionality has been migrated to the logger.
- Added a new line after the command to run for restarting the worker in the error message.
- Included an additional instruction to restart Claude Code after running the worker restart command.
Removes bun-wrapper indirection. Hooks are compiled JavaScript that work perfectly with Node. Worker still uses Bun where performance matters. Fixes#264
- Updated multiple hooks (context-hook, new-hook, save-hook, summary-hook, user-message-hook) to throw errors using `getWorkerRestartInstructions` for improved user guidance on worker connection issues.
- Enhanced `handleWorkerError` function to utilize the new error message generator for consistent error reporting.
- Modified `ensureWorkerRunning` function to provide detailed instructions based on the worker's state, including port information.
- Introduced `getWorkerRestartInstructions` utility in `error-messages.ts` to generate platform-aware error messages for worker failures.
On Windows systems, `localhost` resolves to IPv6 (::1) while the worker
binds to IPv4 (127.0.0.1), causing MCP tool connections to fail.
This change uses the existing getWorkerHost() function which correctly
returns the configured host address (defaulting to 127.0.0.1).
Fixes connection failures on Windows where localhost prefers IPv6.

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

**Problem:**
Worker service crashed on startup with:
TypeError: Cannot read properties of undefined (reading 'get')
at new Wd (.../worker-service.cjs:52:131469)
**Root Cause:**
Circular dependency between SettingsDefaultsManager and logger:
1. SettingsDefaultsManager imports logger
2. logger imports SettingsDefaultsManager
3. logger constructor calls SettingsDefaultsManager.get() at init time
4. When CommonJS resolves the cycle, SettingsDefaultsManager is undefined
**Solution:**
Break the circular dependency by making logger lazy-load its configuration:
- Change logger.level from initialized in constructor to lazy-loaded
- Add getLevel() method that loads on first access
- Update all level checks to use getLevel()
This allows SettingsDefaultsManager to import logger without triggering
the circular dependency, since logger no longer accesses SettingsDefaultsManager
during module initialization.
