R20K-R02 rollback guidance

#!/usr/bin/env bash
# R20K R02 reuses snapshot r20k-pre-0722-071406 and the remote diagnostic owns vpn_test only and restores /etc/config/network from its verified local backup.
# It must not alter active generation, recovery state, quarantine, events or the repair counter.
# If manual recovery is required, use BACKUP_DIR from facts and restore only after inspecting the published diagnostic artifacts.
