+## SESSION 31 SUMMARY — Original Image Storage for Debug Panel
+
+### Problem Identified
+The debug panel was showing the processed (cropped + rotated) image, not the original. This made it impossible to verify that crop bounds and rotation values were correct, since the visualization was of the final result, not the raw input.
+
+### Solution Implemented
+Store the original EXIF-stripped image (before crop/rotation) separately for debugging purposes, accessible from the debug panel.
+
+### Changes Made
+
+**v1.14.5 (Debug Image Storage)**
+
+1. **backend/routers/items.py - `_auto_save_photo_from_extraction()`**:
+   - Before calling `processor.process_photo()`, save the EXIF-stripped `image_bytes` with variant `_debug_original`
+   - Store `original_debug_path` in `db_item.labels_data.image_processing.original_photo_path`
+   - Also store `crop_bounds` and `rotation_degrees` in labels_data for reference
+
+2. **frontend/components/DebugRotationPanel.tsx**:
+   - Add `originalPhotoPath` prop to component interface
+   - Use `displayImageUrl = originalPhotoPath || imageUrl` to prefer original if available
+   - Update useEffect dependency to use `displayImageUrl`
+
+3. **frontend/components/ItemDetailModal.tsx**:
+   - Extract `original_photo_path` from `labels_data.image_processing`
+   - Build full URL using `buildPhotoUrl()` helper
+   - Pass `originalPhotoPath` prop to DebugRotationPanel
+
+### Testing Performed
+- Frontend TypeScript build: ✅ No errors
+- Database structure: ✅ Using existing `labels_data` JSON field (no migrations needed)
+- Component integration: ✅ Props correctly passed through modal → debug panel
+
+**Status:** ✅ **READY FOR TESTING** — Original images now stored and accessible in debug panel
