A.7:5.7 - Match composition to its subject

• System aggregation and delimitation — use B.1.2:4 to coordinate the independently established parts, crossings and whole-characteristic claims needed by the engineering decision. Each characteristic keeps its own aggregation or inference rule.
• Method composition — use B.1.5 to determine whether constituent Methods and their relations construct one reusable way of doing, including its order and branching.
• Temporal aggregation — first establish Work occurrences and temporal parts under A.15.1, or the identities and temporal relations of other subjects under their own rules. B.1.4 combines those recovered relations for a stated window and use.
• Work-resource aggregation — use B.1.6 for resource spend and yields tied to admitted Work, with the required measurements, accounting boundary and aggregation policy.

Normative guard: Select the rule for the actual composition claim. For domain “process” or “behaviour”, recover the object and predicate under its direct rule; it may concern a Method, Work, A.3.4 transformation, A.6.F functional behaviour, mechanism, or another domain object. Add an explicit distinction only when the intended value is not cheaply recoverable.
