"""
Expanded integration tests for atom_agent_endpoints.py (Phase 19, Plan 02).
This test file expands on the existing test_atom_agent_endpoints.py to achieve 50% coverage.
Focus areas:
- Streaming endpoint comprehensive testing
- Error handling edge cases
- Governance integration with all maturity levels
- Feedback system integration
Coverage target: 50% of atom_agent_endpoints.py (368 lines from 757 total)
Current coverage: 8.75% (89/757 lines)
Target coverage: 50% (379/757 lines)
