C.20:1 - Problem Frame

Disciplines can persist while theories, standards, methods, organizations, publications, and vocabulary change. In practice that persistence is carried and refreshed through knowledge canons, codified practices and standards, and institutional carriers such as journals, professional bodies, curricula, committees, and laboratories, while none of those carrier families is identical to the discipline. FPF therefore still needs a typed, provenance-preserving field-level composition account. That persistence cannot be explained by a stable name or by one fixed five-position card. It needs exact constituents, direct constructive part relations, whole-forming facts, a field assembly, a reidentification rule, and a whole characteristic that the composition produces or sustains.

The practice side and knowledge side must both be real. A bibliography without reusable ways of investigating or intervening is a knowledge collection. A method catalogue without field-level claim organization is a repertoire. An institution may sustain both through work, but the institution is still a separately identified system. C.20 asks when exact parts and their couplings warrant one further whole.
