Uncertainty band
A middle range of probabilities, such as 0.30 to 0.70, that maps to an explicit uncertain outcome instead of a hard yes or no.

Definition
The Noul self-consistency cookbook turns a 0.30 to 0.70 band into a three-way map (no, uncertain, yes), so values near the threshold go to human review without another API call. The Choice cookbook uses a similar 0.60 uncertainty gate to raise policy agreement.
Bands are illustrative rather than calibrated, and values near the edges can still flip between uncertain and a hard answer. Their value is making the abstain path explicit in the data instead of hidden in a threshold.
