warnings:
  - STEP_044Q is preview-only: it generates service/timer files in the report workdir but does not install or enable them.
  - Preview cadence is every 2 minutes with 15s randomized delay; no systemd timer is active yet.
  - Next step can install the unit/timer disabled first, or enable timer after a final safety check.
