The "admitted artifact for this run" block named eb95c14 / sha256:4300104..., but experiment 6 is running 29705cb / sha256:0f45468c.... Verified before changing it: 29705cb's receipt is a clean 20/20 with every suite 'pass', its registry_digest matches the running container exactly, and it was cut 04:36 UTC against an 05:01 UTC start. So admission held -- the runbook just was not updated when the image moved. Now says how to check rather than asking the reader to trust the paragraph, since this is what an operator reads mid-incident. Also defines the three terms the file leans on from line 6 onward without ever explaining: "the gate" (semantic-parity.md, proven-equivalence record, not just passing tests), "a receipt" / "admitted artifact" (JSON binding a suite run to an image digest, where skipped blocks admission like a failure), and "cutover" (lifecycle leaves merge, serving stops 503ing).
