A.1.1:4.1 - Select structure, not another holon

Use the four A.22 identity discriminators. The following sketch is a description of the selected organization, not the structure itself and not a relation signature:

BoundedModelUseStructure : U.Structure
  exact constituents:
    one selected model episteme
    exact admitted model-use holons
  exact selected obtaining relations:
    ModelApplicabilityRelation occurrences
    ModelUseRelation occurrences
    ModelExpressionCoherenceRelation occurrences
  exact applied constraint claims used by the selection judgment:
    one exact C.2.1 constraint proposition may refer to a U.ClaimScope or its A.2.6 membership predicate
    other exact applicability, coherence, release, or use-rule constraint propositions applied here
    no bare scope, slice, membership outcome, boundary display, or carrier episteme
  one named selection-use frame:
    exact question
    admissible action
    stop or return condition
  optional nearest non-admissible overread: explanatory only, subject to F.19:4's plausible-reader test

A selection-use frame is the exact plain value formed by the question, admissible action, and stop or return condition; it is not a new kind, card, or record. A phrase such as current use, appropriate structure, or bounded-model-use frame does not fill it. Changing one of those three values changes that identity discriminator. An optional nearest non-admissible overread may explain the use when it passes F.19:4’s plausible-reader test; that explanation is outside the frame’s identity.

The structure depends on its constituents and selected relation organization. It is not a holon whose parts are the substrate systems, Work, methods, or epistemes. Their identities, direct part relations, and any construction or whole-reidentification questions remain separately governed.
