A.15.1:7 - Scope Declaration and Rationale

• Applicability: Use the same occurrence test for pragmatic costing, architecture use, teaching examples, and source or evidence questions; when the current claim is only about a description, publication, source, or evidence relation, apply the direct pattern for that claim.
• Scope declaration: The occurrence head is universal. Temporal semantics use the declared temporal reference. A simple uninterrupted occurrence needs no continuity-policy episteme; identity, episode, retry, resumption, or aggregation claims cite workContinuityPolicyRef and its effective U.ReferenceScheme only when the named use must resolve an ambiguous boundary. Add claim scope, a qualification window, model-use structure, evidence use, or source-currentness assessment only when changing that neighboring fact would change the receiving assertion or reliance; otherwise omit it.
• Rationale: Gives FPF a clean, actionable notion of occurrence with an A.13 agency basis for every actual performer U.System, an independently grounded performance history, an obtaining enactsMethod relation, temporal extent, and containment. When precise assignment-bound attribution is current, a separately checked F.6 relation uses the covering occurrence of the exact directly declared U.SystemRoleAssignment species. Costing, quality, and audit then rest on independently identified Work occurrences rather than plans, recipes, assignments made to act, or a generic role-enactment fact.
