Raised by a generated dependent-presence (x-present-when) guard when the
server returns a response shape that predates the feature — e.g. a lease
token was requested but the payload cannot support the derived presence
contract. It is terminal, not transient: retrying the same request
against the same server can never satisfy the contract, so it is marked
nonRetryable and a job worker stops rather than looping on backoff.
