Add per-source tile rows to support multi-provider imagery (Google
Maps + future UAV). Migration 013 (transactional) introduces
source/captured_at columns, backfills existing rows to
(source='google_maps', captured_at=created_at), and replaces the
4-column unique index with a 5-column index that includes source.
TileRepository:
- ColumnList includes source + captured_at
- GetByTileCoordinatesAsync returns most-recent row across sources
(ORDER BY captured_at DESC, updated_at DESC, id DESC)
- GetTilesByRegionAsync uses DISTINCT ON to pick the most-recent
tile per cell, restoring caller-facing row order
- Insert/Update upsert on the new 5-column conflict key
TileSource enum lives in Common.Enums. Snake_case wire format
(google_maps, uav) is enforced by a focused TileSourceTypeHandler
because the generic ToLowerInvariant pattern would emit
"googlemaps", violating contract v1.0.0.
TileService stamps Source=GoogleMaps + CapturedAt=UtcNow on every
new tile. Tile-storage contract is now frozen at v1.0.0.
AC coverage 7/7. New unit + integration tests cover all ACs;
existing 200 unit + 5 smoke tests preserved.

- Register IHttpClientFactory named client "GoogleMapsTiles" inside
AddTileDownloader() with User-Agent and 100s timeout (preserves
HttpClient's implicit default).
- Resolve the same named client from all three CreateClient() call
sites in GoogleMapsDownloaderV2 (session token, single-tile,
batch-tile retry lambda) and drop the duplicated per-call
UserAgent.ParseAdd setup.
- Expose USER_AGENT, the client name, and the timeout as internal
consts on GoogleMapsDownloaderV2 so the extension and the
downloader share one source of truth.
- Add AC test that builds the DI container, resolves the named
client, and asserts both the User-Agent header and the timeout.
- Archive AZ-374 task file: todo/ -> done/.
175 unit + 5 smoke pass.

- Stop writing "downloaded_YYYY-MM-DD" into tiles.maps_version: new rows
bind @MapsVersion to NULL via TileService.BuildTileEntity.
- Retain the tiles.maps_version column (coderule.mdc forbids unprompted
column drops); pre-existing rows keep their values for forensics.
- Remove MapsVersion property from DownloadTileResponse (API wire shape)
and TileMetadata (internal DTO); OpenAPI schema regenerates from the
DTO via Swashbuckle.
- Add 3 AC tests in TileServiceTests covering the captured-entity write
(AC-1) and the DTO/wire-shape removal (AC-2).
- Update integration-test local DTO + console output; refresh docs in
common_dtos.md, services_tile_service.md, data_model.md.
- Archive AZ-373 task file: todo/ -> done/.
174 unit + 5 smoke pass.

Promotes 8 operational levers into config keys with defaults that match
the prior source literals byte-for-byte:
ProcessingConfig: RegionProcessingTimeoutSeconds (300),
RouteProcessingPollIntervalSeconds (5),
MaxRoutePointSpacingMeters (200), LatLonTolerance (0.0001).
MapConfig: TileSizePixels (256), AllowedZoomLevels ([15..19]),
RetryBaseDelaySeconds (1), RetryMaxDelaySeconds (30).
Sites updated: RegionService, RouteProcessingService,
RoutePointGraphBuilder, RouteValidator, RouteService 4-arg ctor,
RouteImageRenderer, GoogleMapsDownloaderV2, TileService. Closes LF-2 by
forwarding HttpContext.RequestAborted from GetTileByLatLon into the
downloader. appsettings.json gains the 8 new keys at default values.
Tests: 141 / 141 unit + 5 / 5 smoke green. New ConfigDefaultsTests pins
defaults to original literals; new TileService unit test asserts CT
identity from caller to downloader (AZ-371 AC-3).

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.

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).
