 Full UX improvement sweep across all pages and flows. Managed via the `canteen-ux-sweep` kanban board (Hermes Agent).
 
+## Latest Fixes (June 2)
+
+| Commit | Description |
+|--------|-------------|
+| `1e7576e` | Bump SW cache to v9 — phone needs hard-refresh to activate |
+| `e3295af` | GPS coords shown in map popups + asset list; toast on auto-checkin |
+| `120f52a` | Bump SW cache to v8 |
+| `0e53da0` | Fix barcode scan rate 50ms→300ms (decoder thrashing) |
+| `111008a` | Fix ZXing per-frame "no detection" errors treated as camera failures |
+| `6322786` | Fix keyboard-loop on mobile camera failure; guard drawer behind login |
+
+## Route Page (tabRoute)
+
+The route planner loads work orders from the extraction DB, optimizes via TSP (nearest neighbor + 2-opt), and displays a Leaflet map with numbered stops. All API endpoints verified working (26 techs loaded, 6 WOs for today route test).
+
+**To test:** hard-refresh the app on phone to activate SW v9, tap Route tab, select tech, tap Load Route.
+
+## Map Pins & GPS Data
+
+Auto-checkin on scan updates both the `checkins` table AND the asset's `latitude`/`longitude` directly (see `create_checkin()` in server.py lines 1522-1534). Map loads assets via `/api/assets?has_gps=true&limit=2000`. Currently 21 assets with GPS in DB.
+
+GPS coords now show in:
+- Map pin popups (lat/lng below machine ID)
+- Asset list below map (monospace coords next to 📍 indicator)
+- Toast on auto-checkin confirms "GPS saved — check the Map tab"
+
