Definition
The score, cut-off, or confidence floor that decides whether an action runs unattended, goes to a person, or is refused. In a deployment gated by a classifier or a typed decision model, the threshold is where authority is conferred: the model proposes, and the number decides what the institution lets it do.
It matters because thresholds are usually held as configuration, tuned once against one model version and never recorded as a decision. STD-08 §2.6 holds a decision threshold as a policy record whose assumptions name the labelled cases, model version, question schema, and option order it was set against, with a review trigger on any change to them. Where the threshold also chooses what reaches a reviewer, it is part of the intervention specification.
