## ⚠️ Important Notes
### Known Issues
1. **7 Test Entities Remain** (NULL ID issue)
- Run `npm run fix-null-ids` to resolve
- Then optionally re-run cleanup
2. **1 Duplicate Group Remains**
- Same NULL ID entities
- Will resolve with NULL ID fix
3. **Low Description Coverage** (0.5%)
- Not a data integrity issue
- Consider enrichment workflow
### Backup Retention
- **Table**: `entities_cleanup_backup_20251014173740`
