Captures the post-mortem of the April 13 power-cut: incident timeline, retrospective, and architecture/role diagrams. Adds an ADR explaining why Longhorn cannot re-associate orphaned replica directories after a nuclear reinstall (engine-id naming), plus block-device recovery runbooks and the `playbooks/recover/longhorn_data.yml` automation that wires `merge-longhorn-layers.py` to rebuild PVCs from raw `volume-head-*.img` chains. Also extends the k3s_pvc backup to capture Longhorn `volumes`/`settings` CRDs (needed for the fast-path restore) and rewrites the restore script with a fallback dir + English messages.
