warnings:
  - STEP_044U creates Proxmox snapshots for VM130 router-ops and VM121 wg-access-dev after activity sampler timer stability.
  - VM100/VM101 are not snapshotted in this step because their persistent configs were unchanged by sampler timer work.
  - Timer remains enabled/active after snapshots.
