Replace 9 nearly-identical catch blocks in
RegionService.ProcessRegionAsync with a single catch (Exception ex)
that delegates to RegionFailureClassifier.Classify, returning a
typed (category, errorMessage) pair. Preserves all original error
messages stored in region summary files; failure-path call into
HandleProcessingFailureAsync is unchanged.
Net source delta: -38 lines in RegionService, +71 lines in new
RegionFailureClassifier (pure static), +10 unit tests covering
each category, precedence, status-code propagation, null guard.
Tests: 68 unit (was 58) + 5 smoke + 3 stub-contract integration
tests pass.

AZ-353: Centralize 500 handling via GlobalExceptionHandler /
AddProblemDetails / UseExceptionHandler. Sanitized ProblemDetails
body carries a generic title, RFC9110 type link, and the request's
TraceIdentifier as correlationId; the leaky exception message stays
server-side in the ERR log entry. Strip per-endpoint
try/catch (Exception) wrappers and the unused ILogger<Program>
parameters they served. Preserve the typed ArgumentException catch
in CreateRoute (AC-3). The handler maps BadHttpRequestException
back to its framework-supplied StatusCode so model-binding /
malformed-body failures stay 4xx instead of being promoted to 500.
AZ-354: Extract CorsConfigurationValidator (pure static helpers)
and wire it into Program.cs. Production with empty
CorsConfig:AllowedOrigins and no CorsConfig:AllowAnyOrigin opt-in
now throws InvalidOperationException at host startup. Development
keeps the permissive default but logs a warning post-build. Adds
the explicit CorsConfig:AllowAnyOrigin escape hatch.
AZ-356: GetSatelliteTilesByMgrs and UploadImage now return
Results.Problem(StatusCode 501) with ProblemDetails. Added
.ProducesProblem(501) so swagger.json documents the
not-implemented status.
Tests: SatelliteProvider.Tests now references SatelliteProvider.Api
(downward, idiomatic) so unit tests can reach the new helpers.
+9 CorsConfigurationValidator unit tests, +3
GlobalExceptionHandler unit tests, +3 StubAndErrorContractTests
integration tests (added to smoke + full suites).
58/58 unit + 5/5 smoke + 3/3 stub-contract pass.
Code review verdict: PASS.

AZ-351: Resolve ILogger<DatabaseMigrator> directly from DI in
Program.cs instead of casting ILogger<Program> (which always
returned null). Migrator now logs through Serilog at startup.
AZ-352: Drop empty catch in
RouteProcessingService.ExtractTileCoordinatesFromFilename. Convert
the method from private static to internal instance so it can use
the existing _logger (per coderule: side-effecting code must not be
static). Add typed null-guard via ArgumentNullException.ThrowIfNull
so unexpected exceptions propagate. Adds InternalsVisibleTo on the
RouteManagement csproj for SatelliteProvider.Tests, plus 4 unit
tests in RouteProcessingServiceTests.cs covering AC-1 (valid /
malformed / non-numeric) and AC-2 (null path propagation).
AZ-363: Delete _totalEnqueued / _totalDequeued fields and the two
non-atomic ++ writes in RegionRequestQueue. Fields were write-only
dead code and a thread-safety hazard.
Tests: 44/44 unit + 5/5 smoke (scripts/run-tests.sh --smoke).
Code review verdict: PASS, 0 findings, 0 auto-fix attempts.
Batch report: _docs/03_implementation/batch_07_report.md.

Phase B of architecture coupling refactor (epic AZ-309). Replaces
the monolithic SatelliteProvider.Services with three per-component
csprojs to add a compiler-enforced module boundary (resolves F4):
- SatelliteProvider.Services.TileDownloader
- SatelliteProvider.Services.RegionProcessing
- SatelliteProvider.Services.RouteManagement
DI registrations relocated into per-component AddTileDownloader /
AddRegionProcessing / AddRouteManagement extension methods called
from Program.cs. RateLimitException moved to Common/Exceptions/ to
keep the three new csprojs as siblings (no Region->TileDownloader
ProjectReference). Dockerfiles and consumer csprojs (Api, Tests)
rewired to the new project paths. No DI lifetime or hosted-service
order changes.
Build: 0 warn, 0 err. Unit tests: 40/40. Smoke integration: green.

Move cache+DB+download logic for /tiles/{z}/{x}/{y} and
/api/satellite/tiles/latlon out of Program.cs into TileService.
Endpoints now inject only ITileService + ILogger. Service owns
IMemoryCache (1h absolute / 30min sliding preserved). Added
TileBytes DTO; ITileService gains GetOrDownloadTileAsync and
DownloadAndStoreSingleTileAsync. 5 new unit tests cover cache
hit, repo hit, downloader fallback, and AZ-311 happy + error.
Build clean (0/0), unit suite 40/40. Resolves architecture
baseline F3 in code (docs handled by AZ-315).

- Add SatelliteProvider.DataAccess project reference to test csproj
(enables mocking ITileRepository / IRegionRepository / IRouteRepository)
- Replace DummyTest placeholder with InfrastructureTests covering:
* All mockable interfaces (ISatelliteDownloader, repos, queue, services)
can be mocked via Moq
* TileService can be constructed with mocked dependencies
* Test coordinate fixtures load with expected values
- Add Fixtures/TestCoordinates.cs with REG-01..REG-03 + ROUTE-01/04/06
shared test data
- Archive AZ-285 to _docs/02_tasks/done/
- Batch 1 review report: PASS_WITH_WARNINGS (Low/Spec-Gap deferred AC-2,
Low/Maintainability pre-existing FluentAssertions 8.x license note)
Verification: docker dotnet test run — 4/4 tests pass in 2.35s.
