+
+## AC Test Coverage: All covered
+
+| AC Ref | Coverage |
+|--------|----------|
+| AZ-226 AC-1 | `test_eligible_frame_stages_generated_cog_and_sidecar` verifies generated COG and sidecar staging for eligible frames. |
+| AZ-226 AC-2 | `test_high_covariance_generated_tile_write_is_rejected` verifies unsafe high-covariance writes are rejected and not packaged. |
+| AZ-226 AC-3 | `test_sync_package_includes_manifest_delta_sidecar_covariance_and_trust_level` verifies sync package audit metadata. |
+
+## Code Review Verdict: PASS

+# Code Review Report
+
+**Batch**: AZ-226_generated_tile_orthorectification
+**Date**: 2026-05-03
+**Verdict**: PASS
+
+## Findings
+
+No findings.
+
+## Spec Compliance
+
+| Task | AC Coverage | Evidence |
+|------|-------------|----------|
+| AZ-226 | 3/3 covered | `tests/unit/test_tile_manager.py` verifies generated COG/sidecar staging, unsafe covariance rejection, and auditable sync package metadata. |
+
+## Architecture Compliance
+
+- Edits stayed inside `src/tile_manager/**` plus focused unit tests.
+- Generated tile behavior consumes existing Tile Manager and shared contract patterns; no new cross-component internal imports were introduced.
+- Generated outputs use `generated`/`candidate` trust levels and do not promote onboard tiles directly to trusted basemap records.
+
+## Verification
+
+- `.venv/bin/python -m black --check src tests e2e/replay` passed.
+- `.venv/bin/python -m ruff check src tests e2e/replay` passed.
+- `.venv/bin/python -m pytest` passed: 32 tests.
