This is a paid delivery check: we called the endpoint with its own advertised input and compared the response against its own advertised output. It is the one thing free probing cannot see.
Verifiable receipts

Three independent checks, none needing trust in this site: integrity recomputes the id as a hash of the evidence, so any edit shows; verdict re-derives the result offline; raw re-reads the untouched bytes archived at pay time and reproduces the shape.
