A.15.PROD:5.3 - Nested and concurrent attribution

Work structure. Factory work may contain project work, subassembly work, identityClosingWork, and completion-closing work. Every selected work-part relation remains explicit. Jointly necessary concurrent work parts use exact composite work under A.15.1.

Plural minimal composites. Two incomparable minimal work composites yield two local inception claims, each indexed by its exact identity-specification episteme and applicability basis. Nested or concurrent attribution creates no additional inception occurrence, and none of those work compositions establishes transformation composition.

Epistemic basis remains separate. The identity-specification and completion-criterion epistemes remain cited by the local claims. Each applicability basis remains its named predicate or filled local claim, and any C.2.1 edition relation between such epistemes is separate. None is a work participant.
