AZ-357 — eliminate year-based tile cache expiry (LF-1):
- Migration 012: drop 5-col unique index, dedupe by (lat,lon,zoom,
size) keeping max(updated_at), add new 4-col unique index, make
version column nullable + drop default. Column itself preserved
per coderule (column drops require explicit confirmation; tracked
in AZ-373 / C20).
- TileEntity.Version, TileMetadata.Version, DownloadTileResponse.
Version: int -> int? (HTTP shape preserved; field still in JSON).
- TileService.DownloadAndStoreTilesAsync: drop currentVersion year
computation and the .Where(t => t.Version == currentVersion)
cache filter. BuildTileEntity: drop year arg; write Version=null.
- TileRepository: ON CONFLICT now 4-col; lookup queries
ORDER BY updated_at DESC instead of version DESC.
- Tests: replace inverted BT02b with positive AZ357_AC1
(prior-year cached tile is reused). Add BuildTileEntity_
DoesNotPopulateVersion_AZ357 to enforce the no-write contract.
- 69 unit + 5 smoke + 3 stub-contract integration tests pass.
Cumulative code review (batches 7-9, 7 tasks): VERDICT=PASS.
Report at _docs/03_implementation/reviews/batch_09_review.md.
Zero Critical/High/Medium/Low findings. Architecture baseline
remains clean.

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.

Phase C of architecture coupling refactor (epic AZ-309). Closes the
last baseline finding (F5 — DataAccess incorrectly documented as
importing Common) and synchronizes the rest of _docs/02_document/
with the post-split project layout from AZ-312/313/314:
- module-layout.md: per-component sections for the three new csprojs
with explicit ProjectReferences and the no-cross-sibling-reference
invariant the split enforces.
- architecture.md: components and internal-communication tables
updated to show calls flow through Common interfaces.
- architecture_compliance_baseline.md: F1..F5 marked Resolved with
task IDs and commit refs; baseline summary now 0 findings.
- diagrams/components.md, components/03_tile_downloader/description.md,
modules/{common_interfaces,services_tile_service,
services_google_maps_downloader,tests_unit}.md updated for the
split, RateLimitException relocation, and new ITileService methods.
Documentation-only batch — no code, no tests, no build changes.
Epic AZ-309 complete (6 tasks across 3 batches).
