## Batch

| Batch | Tasks | Verdict | Report | Review |
|-------|-------|---------|--------|--------|
| 01 | AZ-1074, AZ-1075 | PASS | `batch_01_cycle9_report.md` | `reviews/batch_01_cycle9_review.md` |

## Tests

- Unit: 448 passed (Docker SDK run via `scripts/run-tests.sh --smoke --skip-format`)
- Integration smoke: passed including `RouteTileDeliveryGrpcTests` (manifest, invalid args, backpressure/SHA256, REST overlap)

## Key changes

- `SatelliteProvider.GrpcContracts/` — canonical `tile_provision.proto` (GrpcServices=Both)
- `RouteTileDeliveryOrchestrator` — lat/lon range validation
- `RouteTileDeliveryGrpcService` — RpcException InvalidArgument for bad input
- `RouteTileDeliveryGrpcTests` + `GrpcTestHelpers` — integration coverage
- Integration-tests Dockerfile — `linux/amd64` build, `aspnet:10.0` runtime
