+## Recent Changes (May 2026 — v3)
 
+- **v3 admin separation** — Admin functionality extracted to separate project `~/projects/canteen-admin-server/` (port 8900). Main `server.py` reduced from 3005→1946 lines by removing admin routes. Main `index.html` reduced from 7645→4228 lines by removing admin UI panels. Admin app live at https://admin.canteen.ourpad.casa.
+- **EXIF GPS extraction** — `/api/ocr` and `/api/upload/photo` now extract GPS coordinates from image EXIF data server-side (PIL getexif()) and return `{exif_gps: {lat, lng}}` alongside results. Raw file bytes preserved — no re-compression, no EXIF stripping.
 - **OCR fix** — Now extracts only the last 5 digits from Connect ID (e.g., `05912-095330` → `95330`). Added `raw_match` field to response for debugging.
 - **Barcode scanner fix** — Switched from `decodeFromVideoElement` to `decodeFromVideoDevice` with 1D-only format hints (Code 128, Code 39, EAN/UPC, ITF, Codabar). Added `TRY_HARDER` hint and 50ms scan interval for fast, reliable detection.
 - **Auto check-in** — New assets automatically check in with GPS on creation (all three entry modes: barcode, OCR, manual). Best-effort: silently skips if GPS unavailable.
 - **Service stability** — Added NPMPlus reverse proxy. Service runs as background process on port 8901.
-- **Admin password** — Updated to `Brett85!@`.
