Definition
Noul criteria clarify boundary cases. Each side can be a string or a structured object with fields such as what, not_for, and examples, mirroring the contrastive style used for Choice options.
They matter most when a question is easy to read two ways: pinning down what counts as a yes and what does not keeps the probability interpretable at the threshold you plan to use.
