-## Enhanced Error Handling & Logging
-
-This patch release improves error message quality and logging across the claude-mem system.
-
-### Error Message Improvements
-
-**Standardized Hook Error Handling**
-- Created shared error handlers (`handleFetchError`, `handleWorkerError`) for consistent error messages
-- Platform-aware restart instructions (macOS, Linux, Windows) with correct commands
-- Migrated all hooks (context, new, save, summary) to use standardized handlers
-- Enhanced error logging with actionable context before throwing restart instructions
-
-**ChromaSync Error Standardization**
-- Consistent client initialization checks across all methods
-- Enhanced error messages with troubleshooting steps and restart instructions
-- Better context about which operation failed
-
-**Worker Service Improvements**
-- Enhanced version endpoint error logging with status codes and response text
-- Improved worker restart error messages with PM2 commands
-- Better context in all worker-related error scenarios
-
-### Bug Fixes
-
-- **Issue #260**: Fixed `happy_path_error__with_fallback` misuse in save-hook causing false "Missing cwd" errors
-- Removed unnecessary `happy_path_error` calls from SDKAgent that were masking real error messages
-- Cleaned up migration logging to use `console.log` instead of `console.error` for non-error events
-
-### Logging Improvements
-
-**Timezone-Aware Timestamps**
-- Worker logs now use local machine timezone instead of UTC
-- Maintains same format (`YYYY-MM-DD HH:MM:SS.mmm`) but reflects local time
-- Easier debugging and log correlation with system events
-- Enhanced worker-cli logging output format
-
-### Test Coverage
-
-Added comprehensive test suites:
-- `tests/error-handling/hook-error-logging.test.ts` - 12 tests for hook error handler behavior
-- `tests/services/chroma-sync-errors.test.ts` - ChromaSync error message consistency
-- `tests/integration/hook-execution-environments.test.ts` - Bun PATH resolution across shells
-- `docs/context/TEST_AUDIT_2025-12-13.md` - Comprehensive audit report
