Every one of these breaks into something that looks like ordinary drift rather
than a defect: a state read moved after the backend include leaves the node
sealed, a token helper fed the first login's stdout gets an empty string on
every rotated deploy and fails later at the first write, an ungated SecretID
swap answers 500 on every deploy that did not rotate, and a swap that never
destroys the old SecretID revokes nothing at all.
