A.3.2:5.5 - Workflow diagram
An episteme whose claims state one reusable method may qualify as U.MethodDescription; a BPMN or object-centric process model may represent those claims. A diagram can also represent a work plan, event-log model, or independently selected structure, so its notation does not settle the exact EntityOfConcern.
If readers treat the diagram as a route that tokens or workers must follow, compare that reading with the source claim. Keep an ordered sequence only when the method claim actually states one. When order comes only from layout, use C.2.P.DR and stop at the represented graph, constraints, objects, or events.
