A model response is valid JSON and matches its response schema. What must happen before it can trigger a refund?

1. Application code must authenticate, authorize, validate business rules, and make retries idempotent.
2. Nothing; schema validity grants permission for the action.
3. The model should repeat the same answer once.
4. The JSON should be frozen with Object.freeze().
