Definition
A Noul answer is the probability of yes. Near 1 is a strong yes, near 0 a strong no, and 0.5 means yes and no are equally likely; it is not a medium skill level or a magnitude.
Because there is no separate confidence, the value itself carries both the decision and the uncertainty, which is why thresholds matter: pick 0.5 when either error is equally easy to act on and go higher when a false yes is expensive.
