+## Recent Changes (May 2026)
+
+### OCR Fix
+Extracts only the last 5 digits from Connect ID stickers.
+- Before: `POST /api/ocr` → `05912-095330`
+- After: `POST /api/ocr` → `95330`
+- Added `raw_match` field to response for debugging
+
+### Barcode Scanner Fix
+- Switched from `decodeFromVideoElement` to `decodeFromVideoDevice`
+- 1D-only format hints (Code 128, Code 39, EAN/UPC, ITF, Codabar)
+- Added `TRY_HARDER` hint for better low-light/angle detection
+- 50ms scan interval (was ~500ms default)
+- **Fixed:** `listVideoInputDevices()` — called on reader instance (not static), with try/catch fallback to default camera
+
+### Auto Check-in on Creation
+New assets automatically check in with GPS coordinates on creation via all three entry modes (barcode, OCR, manual). Best-effort — silently skips if GPS is not available yet.
