A.22:10 - Rationale
FPF needs one general selected-structure kind because many useful claims depend on organization before they depend on a specific architecture, mathematical, measurement, or publication pattern. The selected structure is dependent and non-agentive. Claims about it are carried by separate epistemes and views: it can be described, sourced, compared, coarsened, extracted, or used by architecture.
The selected design keeps A.22 small enough for first use. A practitioner can write one StructureQuestionCard@Project and stop. Heavier describing-use viewpoint selection, independently selected model-use structure, A.6.6 base-dependence, extraction, lens, evidence, and structure-use return records are used only when the next use would otherwise hide loss, source-basis dependence, or a non-structure claim kind.
C.30 defines the direct ArchitectureRelation between one exact holon and one selected A.22 structure. An architecture claim states whether that relation obtains, or describes candidate or expected structure. Architecture descriptions and views are epistemes; publication makes them available. A.22 supplies the selected structure and its identity basis.
