Make Terraform the source of truth for node IPs, remove guest-agent/SSH discovery from the normal workflow path, simplify the bootstrap controller to a fresh-run flow, and swap the initial CNI to Flannel so cluster readiness is easier to prove before reintroducing more complex reconcile behavior.
Provision 3 thin control planes and 3 workers with role-specific sizing and VMID ranges (701/711), generate per-node cloud-init snippets with SSH key injection, and add NixOS kubeadm host/module scaffolding for cp-1..3 and wk-1..3.
