Definition
A Noul asks whether a statement is true and returns the probability that the answer is yes. Near 1 is a strong yes, near 0 a strong no, and near 0.5 means the model gives yes and no equal probability. It is not a degree scale, so it does not measure how much or how strongly.
Optional criteria.true and criteria.false descriptions pin down subtle boundaries. Ask one question per Noul, threshold in code (0.5 when either error is equally easy to act on, higher when a false yes is expensive), and treat middle values as a natural hand-off to a person.
