-**Status:** ✅ **COMPLETE & INTERACTIVE** — Debug panel fully functional for validation and adjustment of crop/rotation
+### Debugging Findings from Real Testing
+Test Image 1 (IMG_6188):
+- AI Detected: Rotation 180°, Crop (353, 213) Size 315×454
+- Correct Values: Rotation -165°, Crop (1411.4, 631.32) Size 1292.76×1784.56
+- **Issue**: AI crop was too tight, missing large portions of the item
+- **Action**: Improved crop prompt to emphasize capturing ENTIRE item with 20-30px padding
+
+**Next Steps**: 
+1. Test with 3-5 more diverse images to identify if tight-crop issue is pattern
+2. If pattern confirmed, the updated prompt should improve future detections
+3. Track which item types (cables, drives, modules) have detection issues
+
+**Status:** ✅ **COMPLETE & DEBUGGED** — Debug panel working, AI prompt improved based on findings
