[jmgilman]

Final validation that the MVP bootstrap is complete and all systems are operational.

Validation Checklist:

Platform Cluster:

• 3 nodes all Ready: kubectl get nodes
• etcd healthy: talosctl etcd status
• Argo CD accessible and healthy
• All Argo CD applications synced

Harvester Cluster:

• 3 nodes all Ready
• Longhorn storage healthy (3 replicas)
• Harvester UI accessible at https://harvester.lab.local
• VM networks configured (VLANs 10, 30, 40, 60)

Networking:

• VyOS gateway operational
• Inter-VLAN routing working
• DHCP relay functional
• Connectivity from home network to lab services

GitOps:

• Platform cluster managed by Argo CD
• Harvester cluster managed by Argo CD
• Changes to Git are reflected in clusters
