+### Backend
+- ✅ File model (app/models/file.py) - UUID PK, vehicle_id FK, all fields
+- ✅ File schemas (app/schemas/file.py) - FileUploadResponse, FileResponse, FileListResponse, FileDeleteResponse
+- ✅ File service (app/services/file_service.py) - upload, get, list, delete, validate_mime_type, validate_file_size
+- ✅ Thumbnail utils (app/utils/thumbnails.py) - 200x200 thumbnails via Pillow for jpg/png/webp
+- ✅ Files router (app/routers/files.py) - GET/POST/GET/DELETE endpoints registered in main.py
+- ✅ Backend tests (tests/test_files.py) - 43 tests, all passing, 82% coverage
 
-## Blockers

-- OPENROUTER_API_KEY added to config.py (empty default, needs env var in production)
-- MAX_FILE_SIZE_MB=50 added to config.py
-- @vitest/coverage-v8 not installed (frontend coverage runs without it)
