C.2.1:1 - Problem Frame
FPF treats an episteme as a holon, not as a document class or a filled record. It is a claim-bearing whole about an exact EntityOfConcern under an effective reference scheme. Carriers, notations, and admissible operations can differ; the identity question is what makes this one episteme and what changes it.
The core constructive question is whether an exact U.ClaimGraph, exact U.Entity, and effective U.ReferenceScheme stand in the relation that makes the claim content interpretable and evaluable as claims about that entity. When they do, their selected organization yields a whole-level epistemic characteristic: the resulting holon can be used as one defeasible or deductive body of knowledge. That characteristic is not supplied by any one participant alone.
Any exact U.Entity can participate as the EntityOfConcern. An episteme can therefore concern another episteme or itself without changing the constitution relation.
Different representation regimes can support different operations. Make the representation and its admitted operations explicit when the current use needs them. Identify the episteme by its claim content, EntityOfConcern, and effective ReferenceScheme.
