F.12:7.4 - Incident duration
Promise: restoration occurs within 60 minutes for each in-scope incident. Delivery Work: each handling occurrence. Evidence: observations of the defined start and restoration events. Evaluation Work applies the elapsed-time rule to those bindings and returns its declared result. A BPMN design may be a MethodDescription under A.3.2, but it is not either Work occurrence or evidence of the result.
