C.24:4.0 - Local objects and boundaries

• ATC.CallRouteDescription is a U.MethodDescription whose EntityOfConcern is the selected admitted Method and whose claims explain how that Method is carried out through the route, under A.3.2. When it carries vendor-local route data, it states the vendor or source scheme, exact scheme or API edition, intended use, and selected Method ref before any access details, inputs, outputs, or route limits.
• ATC.CallPlan is a U.WorkPlan for intended calls. Its steps select Methods and may cite route descriptions.
• ATC.CheckpointReturn is a C.2.1 result episteme stating what was tested, what budget was burned, and what route action is recommended next. It is not the tested Work.
• ATC.CallGraphRef cites the applicable G.6 trace representation over actual call Work. The representation records or points to facts; it creates none of them.

actionBasis contains exactly one of three branches. domainPrescribedAction identifies the applicable domain Method, the exact prescription and its required action, applicability and stop conditions. An optional intended WorkPlan may carry that intention; it establishes neither authority nor permission. No decision wrapper or ongoing Work is required for this branch. situationResponsiveDecisionEpistemeRef refers to an episteme identified under C.2.1 because this plan relies on an A.15.7 decision; the episteme states the selected action, deciding System, intended performer, action-changing fact, relevant Method limit, and stop or feedback condition. fixedOptionChoiceResultRef refers to a C.11 ChoiceResult whose result is choose now. Consuming either decision result here preserves its existing result kind.

There is no catch-all ATC.PolicyRef. When a constraint branch is current, cite its actual object: C.19 PoolPolicyResult or EmitterPolicy, a C.19.1 probe, comparison, local-policy, or waiver result, or a domain constraint whose kind and defining pattern are named. Time, compute, cost, risk, stop, and replan ceilings remain fields of this plan.
