Replaces bare strings with two enums in Common/Enums/:
RegionStatus { Queued, Processing, Completed, Failed }
RoutePointType { Start, End, Action, Intermediate }
Adds a Dapper EnumStringTypeHandler<T> (DataAccess/TypeHandlers/)
that round-trips enums to/from lowercase strings, registered once
at startup via DapperEnumTypeHandlers.RegisterAll(). DataAccess now
references Common (project ref) so entities can carry the enum types.
Sites converted: RegionService (5), RouteProcessingService (3),
RoutePointGraphBuilder (4), entity Status/PointType columns. Log
message and summary file format preserved via .ToLowerInvariant().
API JSON contract preserved by adding JsonStringEnumConverter with
JsonNamingPolicy.CamelCase to the http JSON options — single-word
enum members serialize to the same lowercase strings as before.
DTO renamed: Common.DTO.RegionStatus -> RegionStatusResponse to
free the RegionStatus name for the new enum (forced by the task's
explicit enum name); the renamed DTO has no public-API impact at
the JSON wire level. Stale doc references updated.
AC RT2 in _docs/00_problem/acceptance_criteria.md now lists all 4
point types (start/end/action/intermediate).
Tests: 171 / 171 unit + 5 / 5 smoke green (was 141 + 5; +30 new tests
covering type handler round-trip, set/parse, unknown-value rejection,
idempotent registration, and the AC RT2 doc check).

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)
- 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.
