Evidence and how to verify it yourself

Graded against a source that cannot be a reseller: Coinbase/Kraken median. Returned 64285.0 versus a truth of 64269.8475.

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.
