warnings:
  - STEP_044N is read-only and confirms second-run delta goes to zero after STEP_044M baseline update.
  - The active lease for 10.253.1.10 remains active by state, but has no new activity delta in this second run.
  - Next step can package the sampler as a reusable one-shot script/service, with DB writes guarded by this contract.
