Definition
Criteria define the answer space. For a Choice they are a map of option to description; for a Score an ordered array of 2 to 10 level descriptions; for a Noul an optional description of what yes and no mean. Because the model returns a distribution over exactly these values, criteria are also the schema your code can trust.
Criteria are an extension of the instruction. Aligning the two matters: when instructions and criteria ask for different things, accuracy drops, and a Noul whose true maps to no performs worse than one phrased naturally.
