What does a ClearRun receipt prove, and what doesn't it?
A receipt proves ClearRun issued a specific verdict for specific input and output, at a specific time, and lets anyone check whether it has changed since. It does not prove the answer is true or that the score is right for your use.

It proves
- Who: ClearRun signed it with a key published at
/.well-known/jwks.json. - What: fingerprints (hashes) of the input, the output and the public verdict.
- When: the server time when it was issued.
- Order: it links to the receipt before it in the same workspace.
It does not prove
- That the answer is true. ClearRun does not check facts.
- What the prompt or answer said. The receipt holds hashes, not the text.
- Anything about the model beyond what you sent.
