| Error responses follow standard format | ✓ | Unit tests |

### Quality Infrastructure

| Gate | Status | Validation |
|------|--------|------------|
| At least one unit test per layer | ✓ | pytest |
| Tests use fixtures (no hardcoded data) | ✓ | conftest.py |
| Structured logging configured | ✓ | JSON output |
| CI pipeline defined | ✓ | .github/workflows/ci.yml |

### Packaging & Deployment
