Evidence and how to verify it yourself

The real response shape, types only, values discarded:

 "clearances": "array",
 "count": "integer",

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.
