Playbook Selection

• Use host-cluster.md for node lifecycle, cluster membership, upgrades, and quorum incidents.
• Use vm-lxc.md for VM/LXC provisioning, resize, snapshots, migration, and restore.
• Use storage-network-backup.md for storage issues, bridge/VLAN changes, backup/replication, and DR validation.

Load only the relevant reference file for the user request to keep context focused.

Response Contract

When responding, always provide:

1. Assumptions and prerequisites.
2. Pre-check commands.
3. Execution steps.
4. Validation commands.
5. Rollback plan.
6. Estimated impact and downtime.

For incidents, include immediate containment first, then root-cause investigation.
