✅ Testing Checklist

Local Testing

• Clean Environment: Tested on fresh Ubuntu 22.04+ system
• Script Execution: ./prepare-nodes.sh N completes without errors
• Container Launch: ./setup-nodex.sh succeeds
• Multi-node: Verified with 2+ nodes for resource conflicts
• Logs: No error messages in docker compose logs

Edge Cases

• Large Scale: Tested with 5+ nodes (if applicable)
• Resource Limits: Verified CPU/memory boundaries
• Port Conflicts: No overlap in P2P port assignments
• Permission Issues: Correct file permissions maintained

Platform Compatibility

• Docker Version: Works with Docker 20.0+ and Compose v2
• System Resources: Respects CPU/memory constraints
• File Paths: No hardcoded paths breaking on different systems
