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).

Purpose
Service contracts defining the application's core operations. Implementations live in the per-component service projects (SatelliteProvider.Services.TileDownloader, SatelliteProvider.Services.RegionProcessing, SatelliteProvider.Services.RouteManagement). Cross-component runtime calls between Layer-3 components flow exclusively through these interfaces — there are no compile-time ProjectReference entries between the three sibling service projects.
Public Interface
ITileService
DownloadAndStoreTilesAsync(double lat, double lon, double sizeMeters, int zoomLevel, CancellationToken) → Task<List<TileMetadata>>: downloads missing tiles for a region and returns all tile metadata (existing + new)GetTileAsync(Guid id) → Task<TileMetadata?>: retrieve a single tile by IDGetTilesByRegionAsync(double lat, double lon, double sizeMeters, int zoomLevel) → Task<IEnumerable<TileMetadata>>: query tiles within a geographic regionGetOrDownloadTileAsync(int z, int x, int y, CancellationToken) → Task<TileBytes>: serve a tile by Z/X/Y, hitting cache, then repository, then downloader (added in AZ-310)DownloadAndStoreSingleTileAsync(double latitude, double longitude, int zoomLevel, CancellationToken) → Task<TileMetadata>: download one tile by lat/lon and persist (added in AZ-311)
IRegionService
RequestRegionAsync(Guid id, double lat, double lon, double sizeMeters, int zoomLevel, bool stitchTiles) → Task<RegionStatus>: creates a region record and enqueues for async processingGetRegionStatusAsync(Guid id) → Task<RegionStatus?>: retrieves current status of a region requestProcessRegionAsync(Guid id, CancellationToken) → Task: executes tile downloading, CSV/summary generation, optional stitching
IRouteService
CreateRouteAsync(CreateRouteRequest request) → Task<RouteResponse>: validates input, calculates intermediate points, persists route + points, optionally creates geofence regionsGetRouteAsync(Guid id) → Task<RouteResponse?>: retrieves route with all points
ISatelliteDownloader
GetTiles(GeoPoint geoPoint, double radiusM, int zoomLevel, CancellationToken) → Task: legacy interface for tile downloading (not directly implemented byGoogleMapsDownloaderV2)
IRegionRequestQueue
EnqueueAsync(RegionRequest request, CancellationToken) → ValueTask: add region request to the bounded queueDequeueAsync(CancellationToken) → ValueTask<RegionRequest?>: consume next request (blocks until available)Count(int): current queue depth
