No findings.

## Spec Compliance

| Task | AC Coverage | Evidence |
|------|-------------|----------|
| AZ-223 | 3/3 covered | `tests/unit/test_camera_ingest_calibration.py` verifies packet metadata, blackout unusability, and raw-frame retention rejection. |
| AZ-224 | 3/3 covered | `tests/unit/test_mavlink_gcs_integration.py` verifies telemetry normalization, invalid GPS_INPUT rejection, and QGC status rate limiting. |
| AZ-225 | 3/3 covered | `tests/unit/test_tile_manager.py` verifies trusted cache activation, tamper/staleness rejection, and explicit metadata lookup rejection. |
| AZ-227 | 3/3 covered | `tests/unit/test_fdr_observability.py` verifies append/index behavior, rollover reporting, and export evidence artifacts. |

## Architecture Compliance

- Component writes stayed within the owning package directories declared in `_docs/02_document/module-layout.md`.
- Cross-component imports use shared public contracts and shared error envelopes only.
- No direct imports of another runtime component's internal modules were introduced.

## Verification

- `.venv/bin/python -m ruff check src/camera_ingest_calibration src/mavlink_gcs_integration src/tile_manager src/fdr_observability tests/unit/test_camera_ingest_calibration.py tests/unit/test_mavlink_gcs_integration.py tests/unit/test_tile_manager.py tests/unit/test_fdr_observability.py` passed.
- `.venv/bin/python -m pytest tests/unit/test_camera_ingest_calibration.py tests/unit/test_mavlink_gcs_integration.py tests/unit/test_tile_manager.py tests/unit/test_fdr_observability.py` passed: 12 tests.
