An uncoded 4xx (gateway 404, 408, 410, unknown code) is Unknown: Refused wipes sealed proofs. Unrecognized leaves the refusal enum.
The catch lists no types: only the caller's cancellation propagates. moveId and reversesMoveId patterns use \z in client and fake,
so a trailing line feed is refused as Heimdall's ajv refuses it; 64, 65 and newline are pinned.
