 "description": "FROZEN after publication; changes only at an announced version boundary with a new schema_version. One signed verdict about one Solana transaction: did tx credit amount atomic units of mint to payee (and optionally was payer a signer). Single top-level verdict, no composition. Two refusal shapes (400 invalid subject, 503 signing unavailable) are part of the contract from the first version.",
