Generated: $(date)

## Summary

This report identifies:
- VMID inconsistencies
- IP address inconsistencies  
- Configuration gaps
- Missing dependencies
- Unreferenced or obsolete files

---

## 1. VMID Consistency

### Expected VMID Ranges
- **Validators**: 1000-1004 (5 nodes)
- **Sentries**: 1500-1503 (4 nodes)
- **RPC**: 2500-2502 (3 nodes)

### Issues Found
