## Code Review Verdict: PASS
## Auto-Fix Attempts: 0
## Stuck Agents: None
## Verification
- `python3 -m pytest tests/blackbox`: 18 passed.
- IDE lints: no errors on changed Python files.
- `python3 -m black ...` and `python3 -m ruff ...` could not run because those optional dev tool modules are not installed in the current interpreter.
## Next Batch: AZ-238, AZ-239

# Code Review Report
**Batch**: AZ-234_replay_geolocation_confidence_tests, AZ-235_vio_replay_performance_tests, AZ-236_satellite_anchor_cache_tests, AZ-237_mavlink_blackout_spoofing_tests
**Date**: 2026-05-05
**Verdict**: PASS
## Findings
| # | Severity | Category | File:Line | Title |
|---|----------|----------|-----------|-------|
No findings.
## Review Notes
- Spec compliance: all ACs for AZ-234 through AZ-237 are covered by focused blackbox tests.
- Scope: tests use public runtime packages (`vio_adapter`, `satellite_service`, `anchor_verification`, `safety_anchor_wrapper`, `mavlink_gcs_integration`) and test-side harness helpers only.
- Security quick-scan: no external network access, dynamic execution, shell invocation, or secrets were introduced.
- Architecture: no runtime internals or private component modules are imported by the blackbox tests.
