**Pass criterion**: route.Id matches; points count matches creation response

## BT-08: Route with Map Processing

**Trigger**: POST /api/satellite/route with requestMaps=true, 2 points, regionSize=300
**Expected**: Route maps processed, stitched image and CSV created
**Pass criterion**: mapsReady=true; stitchedImagePath non-empty; csvFilePath non-empty; stitched image > 1024 bytes

## BT-09: Route with Tiles ZIP

**Trigger**: POST /api/satellite/route with requestMaps=true, createTilesZip=true, 2 points
**Expected**: ZIP file created with tiles
**Pass criterion**: tilesZipPath non-empty; ZIP > 1024 bytes; ZIP entry count = unique tiles in CSV; entries start with "tiles/"; path has ≥5 parts (directory structure preserved)
**Timeout**: 180s

**Trigger**: POST /api/satellite/route with 10 waypoints, requestMaps=true, regionSize=300
**Expected**: All points interpolated; map tiles processed
**Pass criterion**: mapsReady=true; uniqueTileCount ≥ 10; stitched image > 1024 bytes
**Timeout**: 240s

## BT-11: Route with Geofences (10 points + 2 rectangles)

**Trigger**: POST /api/satellite/route with 10 waypoints + 2 geofence polygons, requestMaps=true
**Expected**: Geofence regions created and processed
**Pass criterion**: mapsReady=true; uniqueTileCount ≥ 10; stitched image > 1024 bytes; geofence regions linked to route
**Timeout**: 240s

## BT-12: Extended Route (20 points, maps)

**Trigger**: POST /api/satellite/route with 20 waypoints in separate geographic area, requestMaps=true
**Expected**: Large route processed completely
**Pass criterion**: mapsReady=true; uniqueTileCount ≥ 20; stitched image > 1024 bytes
**Timeout**: 360s
