DateTime Timezone Handling (Critical Bug Fix): - Updated all models to use DateTime(timezone=True) for PostgreSQL - Changed datetime defaults to lambda: datetime.now(timezone.utc) - Fixed mixing of timezone-aware and timezone-naive datetime objects - Resolved Internal Server Errors in session completion endpoint - Affected models: User, Team, Tree, Session, Attachment Production Logging System: - Created logging_config.py with structured logging setup - Added log rotation (10MB files, 10 backups) for production - Implemented RequestLoggingMiddleware with correlation IDs - Added ErrorLoggingMiddleware for comprehensive error tracking - Integrated logging into main.py application startup - Supports dev/prod modes with appropriate log levels Integration Tests - Session Workflow: - Created test_sessions.py with 12 comprehensive tests - Session lifecycle: create, update, complete - Session export in multiple formats (markdown, text, HTML) - Error handling and authorization checks - Added pytest.ini with coverage configuration - Added requirements-dev.txt with pytest dependencies Following 2026 FastAPI best practices for timezone handling and structured logging.
