Coverage expansion tests for calendar tool.
Tests cover critical code paths in:
- tools/calendar_tool.py: Calendar operations via Google Calendar
- Event creation, updates, deletion, conflict checking
- Governance enforcement for calendar operations
- Authentication and error handling
Target: Cover critical paths (happy path + error paths) to increase coverage.
Uses extensive mocking to avoid Google Calendar API dependencies.
