Implements T-1.5 findings F1/F2 (author-first, no cluster change). F1 (tofu): refactor libvirt node resources count -> for_each keyed by node name so single-node -replace/destroy cannot cascade to siblings. Add ordered-list/primary helper locals; update outputs.tf off the map; add moved.tf (12 moved blocks). tofu plan proves a pure state-address migration: 0 to add, 0 to change, 0 to destroy (all 12 'has moved to'). State-persist via a 0-change apply is operator-permission-gated. F2 (ansible): k3s_server secondary fetches the join token via delegate_to the primary (published fact as fast path), so a single-node rejoin with --limit k3s-dev-N is self-contained and no longer depends on a fact an earlier play had to set. Syntax-check + CI gate green. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
infra/ — Phase 1 node provisioning (local KVM)
OpenTofu (libvirt) + cloud-init + Ansible bring up the 3-node k3s/Cilium cluster. See PHASE1-SCOPE.md. Spec: ../home-network-k3s/docs/02-environments-and-provisioning.md.
