+The model answers one boolean question: do the changed lines need correction to
+satisfy the rule? A yes means a changed passage violates a requirement.
 TypeSafe's [Noul primitive](https://docs.typesafe.ai/primitives/noul) returns the
 probability of yes, without a separate confidence score. Judgement flags a violation
 at or above the rule's threshold. Every lower score, including 0.5, produces no
