C.2:1 - Problem Frame

FPF fixes two archetypal sub-holons: U.System (physical/operational) and U.Episteme (knowledge holon). KD-CAL is the primary composition pattern for U.Episteme, giving engineers a compact, testable way to say (a) how strictly an episteme is written (F), (b) where its exact claim is asserted to apply (G), (c) how well that claim is warranted by evidence or severe tests (R), and (d) how closely two epistemes coincide (CL). C.2.1 supplies the constitution test: exact claim content, one exact EntityOfConcern, and one effective U.ReferenceScheme. Grounding, edition, viewpoint, view, representation, publication, form, and carrier remain neighboring objects or relations under their direct patterns.
