# REST check runs do not expose per-attempt creation time. The endpoint is
# intentionally queried with filter=latest; select the highest immutable run ID
# for the trusted producer and require that returned attempt to have completed
# successfully by merge. Any ordinary post-merge rerun therefore fails closed
# and needs operator inspection. DCO alone has a bounded five-minute exception.
