A.3.4:1 - Problem Frame

FPF often needs to talk about change in physical systems, engineered artifacts, organizations, presentation carriers, constituent organizations, architectures, programs, regulatory situations, and research objects. A revised specification needs an early split: changed claim content identifies two C.2.1 epistemes, not one continuing changed episteme. Test the EpistemeEditionRelation between them. Open A.3.4 only for a continuing carrier, constituent organization, or other subject with its own identity rule; if revision U.Work first creates the later episteme, use A.15.PROD for that first existence. When the source says process, editing, or construction, recover the changed object from the case.

For transformer constitution use A.3; for signatures and slot discipline use A.6.0 and A.6.5; for problem-to-work carry-through use E.18.1. Section 0 and sections 4.4–4.5 provide the other neighboring routes.

What is missing is a positive first route: identify the actual change, then open only the separate method, work, flow, representation, evidence, publication, or later-use claim the practitioner is making.
