Step 13 (Update Docs) for cycle 2. Most cross-cutting docs were already updated during Step 10 (architecture.md, glossary.md, components/03_tile_downloader, modules/api_program.md, data_model.md, contracts/api/uav-tile-upload.md). This commit completes the remaining module-level + module-layout updates and writes the cycle-2 ripple log. * modules/common_configs.md: + UavQualityConfig section and appsettings-section row (UavQuality). * modules/common_dtos.md: + UavTileMetadata, UavTileBatchMetadataPayload, UavTileBatchUploadResponse, UavTileUploadResultItem, UavTileUploadStatus, UavTileRejectReasons (closed enumeration v1.0.0). * module-layout.md: refresh Common (+ UavQualityConfig + UAV DTOs), TileDownloader (+ UavTileQualityGate, UavTileUploadHandler, + SixLabors.ImageSharp 3.1.11 PackageReference), and WebApi (+ Authentication/*, DTOs/UavTileBatchUploadRequest, + JwtBearer 8.0.21 PackageReference). Updates the "Last Updated" stamp to cycle 2. * modules/tests_unit.md: replace the obsolete "only a dummy test" description; add cycle-2 AZ-487 / AZ-488 test classes (AuthenticationServiceCollectionExtensionsTests, JwtTokenFactoryTests, UavTileQualityGateTests, UavTileUploadHandlerTests, UavTileFilePathTests, PermissionsRequirementTests) + new ProjectReference / package references. * modules/tests_integration.md: + JwtIntegrationTests, UavUploadTests (incl. wall-clock-seeded coordinate counter rationale from the Step 11 fix), and the StubAndErrorContractTests update for the removed 501 stub. * ripple_log_cycle2.md (new): cycle-2 reverse-dependency scan results showing every importer of the new symbols resolves inside the three already-updated components (WebApi, TileDownloader, Common). No unexpected ripple, no heuristic fallback needed. Co-authored-by: Cursor <cursoragent@cursor.com>

# Module: Common/Configs
|
|
|
|
## Purpose
|
|
Configuration POCOs that bind to `appsettings.json` sections via `IOptions<T>` pattern.
|
|
|
|
## Public Interface
|
|
|
|
### MapConfig
|
|
- `Service` (string): map provider name (e.g., "GoogleMaps")
|
|
- `ApiKey` (string): API key for the map provider
|
|
|
|
### StorageConfig
|
|
- `TilesDirectory` (string): base path for tile storage (default: `/tiles`)
|
|
- `ReadyDirectory` (string): base path for output files (default: `/ready`)
|
|
- `GetTileSubdirectoryPath(int zoomLevel, int tileX, int tileY) → string`: computes bucketed subdirectory path (`{tiles}/{zoom}/{xBucket}/{yBucket}`) using integer division by 1000
|
|
- `GetTileFilePath(int zoomLevel, int tileX, int tileY, string timestamp) → string`: computes full file path with timestamped filename (`tile_{z}_{x}_{y}_{ts}.jpg`)
|
|
|
|
### ProcessingConfig
|
|
- `MaxConcurrentDownloads` (int, default: 4): semaphore limit for parallel tile downloads
|
|
- `MaxConcurrentRegions` (int, default: 3): parallel region processing workers
|
|
- `DefaultZoomLevel` (int, default: 20): fallback zoom level
|
|
- `QueueCapacity` (int, default: 100): bounded channel capacity for region request queue
|
|
- `DelayBetweenRequestsMs` (int, default: 50): throttle delay between Google Maps requests
|
|
- `SessionTokenReuseCount` (int, default: 100): tiles per session token before rotation
|
|
|
|
### DatabaseConfig
|
|
- `ConnectionString` (string): DB connection string (unused — connection string is resolved directly from `IConfiguration` in `Program.cs`)
|
|
|
|
### UavQualityConfig
|
|
Knobs for the 5-rule UAV tile quality gate (`UavTileQualityGate`) and the multipart upload envelope. Bound from the `UavQuality` section in `appsettings.json`.
|
|
- `MinBytes` (int, default: `5 * 1024` = 5 KiB): lower bound for Rule 2 (`SIZE_OUT_OF_BAND`).
|
|
- `MaxBytes` (int, default: `5 * 1024 * 1024` = 5 MiB): upper bound for Rule 2; also drives `KestrelServerOptions.Limits.MaxRequestBodySize = MaxBatchSize * MaxBytes` and `FormOptions.MultipartBodyLengthLimit` in `Program.cs`.
|
|
- `MaxAgeDays` (int, default: 7): Rule 4 cutoff for `CAPTURED_AT_TOO_OLD`.
|
|
- `CapturedAtFutureSkewSeconds` (int, default: 30): Rule 4 forward clock-skew tolerance for `CAPTURED_AT_FUTURE`.
|
|
- `MinLuminanceVariance` (double, default: 10.0): Rule 5 threshold for `IMAGE_TOO_UNIFORM` measured on a downsampled `L8` image.
|
|
- `MaxBatchSize` (int, default: 100): hard cap on per-request batch length; violations return 400 envelope-level (see AC-8, RL-05).
|
|
- `LuminanceSampleSize` (int, default: 32): edge length of the square downsample fed into Rule 5; keeps the per-item gate cost bounded.
|
|
|
|
## Internal Logic
|
|
`StorageConfig.GetTileSubdirectoryPath` buckets tiles by dividing X/Y coordinates by 1000, preventing filesystem performance degradation from too many files in one directory.
|
|
|
|
## Dependencies
|
|
None (pure POCOs, no internal imports).
|
|
|
|
## Consumers
|
|
- `Program.cs` — binds from config sections via `builder.Services.Configure<T>()`
|
|
- `GoogleMapsDownloaderV2` — reads `MapConfig`, `StorageConfig`, `ProcessingConfig` via `IOptions<T>`
|
|
- `RegionService` — reads `StorageConfig`
|
|
- `RegionProcessingService` — reads `ProcessingConfig`
|
|
- `RouteProcessingService` — reads `StorageConfig`
|
|
- `RegionRequestQueue` — receives `QueueCapacity` as constructor param
|
|
|
|
## Data Models
|
|
No domain entities; these are configuration DTOs.
|
|
|
|
## Configuration
|
|
These classes **define** the configuration shape consumed by all services.
|
|
|
|
| Config Class | appsettings Section |
|
|
|-------------|-------------------|
|
|
| MapConfig | `MapConfig` |
|
|
| StorageConfig | `StorageConfig` |
|
|
| ProcessingConfig | `ProcessingConfig` |
|
|
| DatabaseConfig | (not wired — connection string read directly) |
|
|
| UavQualityConfig | `UavQuality` (added in AZ-488; consumed by `UavTileQualityGate`, `UavTileUploadHandler`, and `Program.cs` request-size limits) |
|
|
|
|
## External Integrations
|
|
None.
|
|
|
|
## Security
|
|
`MapConfig.ApiKey` holds the Google Maps API key. In production, injected via environment variable `MapConfig__ApiKey`.
|
|
|
|
## Tests
|
|
No dedicated tests.
