## Corrections Applied

### 1. data_model.md — Removed `stitched_image_path` from regions table

**Issue**: Listed `stitched_image_path` as a column on the `regions` table.
**Reality**: `RegionEntity` has no such property. Stitched images for regions are generated to disk but the path is only written to the summary text file, not stored as a DB column. `StitchedImagePath` only exists on `RouteEntity`.
**Fix**: Removed from ERD and table definition in `data_model.md`.

## Entity Verification

All classes, interfaces, and types mentioned in documentation were cross-referenced against the codebase:

- **Entities** (4/4): TileEntity, RegionEntity, RouteEntity, RoutePointEntity ✓
- **Service interfaces** (5/5): ITileService, IRegionService, IRouteService, IRegionRequestQueue, ISatelliteDownloader ✓
- **Service implementations** (7/7): TileService, RegionService, RouteService, GoogleMapsDownloaderV2, RegionProcessingService, RouteProcessingService, RegionRequestQueue ✓
- **Repositories** (6/6): ITileRepository, IRegionRepository, IRouteRepository, TileRepository, RegionRepository, RouteRepository ✓
- **Config classes** (4/4): MapConfig, StorageConfig, ProcessingConfig, DatabaseConfig ✓
- **DTOs** (10/10): GeoPoint, Direction, TileMetadata, RegionRequest, RegionStatusResponse, RouteResponse, RoutePoint, RoutePointDto, CreateRouteRequest, GeofencePolygon ✓
- **Utilities** (1/1): GeoUtils ✓
- **Infrastructure** (1/1): DatabaseMigrator ✓

## Interface Accuracy

All method signatures in component/module docs verified against actual code. No discrepancies found.

## Flow Correctness

- F1 (Single Tile): TileService → TileRepo → GoogleMaps → FileSystem ✓
- F2 (Region Request): RegionService → RegionRepo → Queue ✓
- F3 (Region Processing): BackgroundService → TileService → FileSystem → RegionRepo ✓
- F4 (Route Creation): RouteService → GeoUtils → RouteRepo ✓
- F5 (Route Map Processing): RouteProcessingService → RegionService → Queue → ZIP ✓
- F6 (Status Query): Direct DB lookup ✓

## Remaining Gaps (Minor)

1. **Tile serving endpoint**: `GET /tiles/{z}/{x}/{y}` serves raw tile images from disk. Not documented in system-flows as it's a trivial static file serve. Noted in architecture as implicit.

## Consistency Check

- Component docs ↔ Architecture doc: consistent ✓
- Flow diagrams ↔ Component interfaces: consistent ✓
- Data model ↔ Migration SQL: consistent (after correction) ✓
- Module layout ↔ Actual file paths: consistent ✓

## Note on AGENTS.md Discrepancy

The project's `AGENTS.md` mentions `geofence_polygons` as a field on the `routes` table. This is inaccurate — geofence polygons are passed in `CreateRouteRequest` but are NOT persisted on the routes table. Their effects are stored indirectly via `route_regions.is_geofence` and `route_regions.geofence_polygon_index`. The generated documentation correctly omits this non-existent column.
