warnings:
  - This step replaces env-driven service mode with explicit config-file mode.
  - It intentionally runs periodic --commit for a short canary window against a temporary selector imbalance.
  - After the canary window it restores selector/state and leaves the service enabled/running in --dry-run mode.
