A hydroelectric gate advisor is about to recommend opening a spillway. The night operator must be able to stop that act in time so the river below is not put at risk. Security, not the control-room “ease of use” checklist, owns that freeze. Which 25059 characteristic is that?

Short Explanation

Stopping a spillway open in time so the river is not put at risk is intervenability: a timely operator freeze to prevent harm, under security. That is not the control-room ease-of-use checklist, not a miss-rate band, and not a model-card link.

Full Explanation

Intervenability is a timely operator stop that prevents harm and sits under security. Controllability is a different parent (interaction capability). Correctness and transparency misclassify the freeze.
