Validation, Retry, and Feedback Loops
Validation questions turn on which failures a check can actually catch. A syntax and type check passes a total that contradicts its own line items, so relationships between values need arithmetic the code can do without the model. Self-checking shares the failure it is meant to catch, since a value misread for a reason is confirmed for the same reason. On retries, the distinction is whether the failure is variable or systematic: resending an identical request is a fresh sample and fails about as often as it succeeds, feeding back what was produced and what was wrong turns it into a correction, and a schema that is wrong about the documents is not fixed by any number of attempts.
