? What a verified receipt does and does not prove
It does prove
- These exact bytes were signed by the key the receipt names, and have not changed since.
- The action, actor, capability, environment and timestamp inside the signed payload are the ones that were bound at signing time — not a label added afterwards.
- The record occupies its own link in an append-only proof chain.
It does not prove
- Completeness. A receipt proves what it records. It cannot prove that everything else which happened was also recorded — that is a property of the execution boundary, not of a signature.
- That the decision was correct. Verification establishes provenance and integrity, never that the policy behind the outcome was the right policy.
- Anything about fields marked absent below. Where a fact is not in the signed bytes, this page says so instead of supplying one.
