A surface that takes a job takes a set, and verified it against a seal over its head as if over the whole result, so a good set read as invalid. The provider path checks its own receipt before giving it: a provider's word reaches the seal. A made receipt is pinned by digest, and generate.py --self-test shows each way the pins fail. The corpus gains two receipts by the first form's own writer, from the service as it was on 18 October. A second verifier's reading settled four sentences of section 8, and -0 as an index, where the two disagreed. Co-Authored-By: Claude Opus 5.5 <[email protected]>
