- Implement burn execution: download with checksum, write via dd/etcher-equivalent, mount boot/root to inject hostname/IP/k3s tokens/labels/taints, journald/GC drop-ins, and Longhorn fstab entries. Add Windows writer (diskpart + wmic) and Linux writer (dd + sgdisk) paths.
- Add Keycloak/SSH bootstrap: ensure ssh user, authorized keys, and k3s token/URL injection for agents; control-plane restore path with etcd snapshot selection.
- Add per-host inventory entries for tethys, titan-db, titan-jh, oceanus/titan-23, future 20/21 once audited.
