How to use this checklist
This is the gate before a repository is allowed to carry anything that runs in production — pipelines, plans, manifests, secrets references. It is deliberately blunt: a repo without protection, ownership, and a clean history is not a production repo, regardless of how clean its working tree looks at HEAD.
Work through it during the initial onboarding of a repository and again on a quarterly cadence afterwards, because every one of these items decays: people leave, bypass lists grow, dependencies rot. A repo that passed this list last quarter and has had no reviews since should be treated as failing it now.
Sign-off
Every critical item must pass. A failing critical item blocks the repository from being used by a production pipeline; it is not a note for later. Record the date, the reviewer, and the disposition of every item that did not pass.
