Remote changes:
- Proxmox snapshot metadata/disk checkpoint
- VM101 runtime backup under /root/router-ops-backups
- no network/firewall/policy changes beyond already completed vpn3/vpn4/vpn5 isolated runtime pool

Next:
- if PASS_GOOD_ISOLATED_POOL_CHECKPOINT, next phase can design firewall/policy integration, still with staged rollback
