Noul question

A noul question is Laya's binary primitive, inherited from the Jev protocol: ask whether a statement holds for the state and get back a probability. "Noul" is Jev's name for this type; think of it as a calibrated boolean.

Shape

criteria is optional. If present it is a dict with true and/or false descriptions:

"is_phishing": {
  "type": "noul",
  "instructions": "Is this email a phishing or scam attempt?",
  "criteria": {"true": "phishing, scam, or fraud", "false": "a legitimate email"}
}

Internally it is always rendered as two option markers, false: … then true: …, with defaults "no, the statement does not hold" and "yes, the statement holds".

The answer is noul (the probability of true, 0 to 1), confidence = max(p, 1 − p) (never below 0.5), and an action block. Threshold on noul directly: flag at 0.5 for balanced costs, lower for recall-critical checks such as threats, higher when false positives are expensive.

Known issue: label following

The model card documents that noul can follow its option labels rather than the state, most strongly on the English checkpoint: the "false:"/"true:" pair can dominate and return a confident "no" for clearly positive input (issue #156). Check noul answers on your own data. If they look stuck, ask the same thing as a two-option choice question with neutral keys:

{"type": "choice", "instructions": "Is this review positive?",
 "criteria": {"A": "yes, the review is positive", "B": "no, the review is negative"}}

On the fine-tuned typed-decisions benchmark, noul is the strongest primitive (0.857). See choice, score and noul.
