## Files Changed

New:
- `SatelliteProvider.Services.TileDownloader/SatelliteProvider.Services.TileDownloader.csproj`
- `SatelliteProvider.Services.TileDownloader/TileDownloaderServiceCollectionExtensions.cs`
- `SatelliteProvider.Services.RegionProcessing/SatelliteProvider.Services.RegionProcessing.csproj`
- `SatelliteProvider.Services.RegionProcessing/RegionProcessingServiceCollectionExtensions.cs`
- `SatelliteProvider.Services.RouteManagement/SatelliteProvider.Services.RouteManagement.csproj`
- `SatelliteProvider.Services.RouteManagement/RouteManagementServiceCollectionExtensions.cs`
- `SatelliteProvider.Common/Exceptions/RateLimitException.cs`

Moved (with namespace updates):
- `TileService.cs`, `GoogleMapsDownloaderV2.cs` → `SatelliteProvider.Services.TileDownloader/`
- `RegionService.cs`, `RegionProcessingService.cs`, `RegionRequestQueue.cs` → `SatelliteProvider.Services.RegionProcessing/`
- `RouteService.cs`, `RouteProcessingService.cs` → `SatelliteProvider.Services.RouteManagement/`

Modified:
- `SatelliteProvider.Api/Program.cs` (DI cleanup + namespace usings)
- `SatelliteProvider.Api/SatelliteProvider.Api.csproj` (3 new ProjectReferences)
- `SatelliteProvider.Api/Dockerfile` (COPY new csproj paths)
- `SatelliteProvider.IntegrationTests/Dockerfile` (drop stale COPY of old Services csproj)
- `SatelliteProvider.Tests/SatelliteProvider.Tests.csproj` (3 new ProjectReferences)
- `SatelliteProvider.Tests/InfrastructureTests.cs`, `TileServiceTests.cs`, `RegionServiceTests.cs`, `RouteServiceTests.cs`, `RegionRequestQueueTests.cs` (using updates)
- `SatelliteProvider.sln`

Deleted:
- `SatelliteProvider.Services/` directory (csproj + 7 source files moved out)

## AC Test Coverage

11 of 11 ACs across the 3 tasks covered. Build/test acceptance verified by `dotnet build` (0 warn, 0 err), 40/40 unit tests, and smoke integration suite passing end-to-end.

## Code Review Verdict

**PASS** — no findings. See `_docs/03_implementation/reviews/batch_05_review.md`.

## Auto-Fix Attempts

1 (in-batch): `RateLimitException` was originally defined in `GoogleMapsDownloaderV2.cs` (TileDownloader) and caught in `RegionService.cs` (RegionProcessing). After the split, this would have required a `RegionProcessing → TileDownloader` ProjectReference (cross-Layer-3 dependency). Resolved by relocating the exception to `SatelliteProvider.Common/Exceptions/`.

## Build / Tests

- `dotnet build SatelliteProvider.sln --configuration Release` → 0 warnings, 0 errors (47.98s)
- `dotnet test SatelliteProvider.Tests` → 40/40 passed (1.93s)
- `./scripts/run-tests.sh --smoke` → all integration tests pass end-to-end (~2 min)

## Architecture-Baseline Impact

- F4 (Medium — single Services csproj packs three components): **resolved** by project split. Compiler now enforces the layer-3 sibling boundary.
- F3 (Medium — already resolved in Batch 4): no regression.
- Documentation sync (`module-layout.md`, `architecture.md`) deferred to AZ-315 (Batch 6).

## Next Batch

AZ-315 (Phase C — documentation sync: update `architecture.md` and `module-layout.md` to reflect the split, then close epic AZ-309).
