A.6.0:4.9 - Recover formal-substrate and PrincipleFrame uses by direct governing relation

Current claimDirect governed use
Author, select, or cite a formal declarationUse U.Signature(profile=FormalSubstrate) with its subject, vocabulary, inference kinds, laws, applicability, and real dependencies.
Use a mathematical object to preserve selected structure while hiding other structureUse C.29 and state the mathematical-lens relation.
Declare, apply, or realize an operationUse A.6.1 for the OperationAlgebra, typed argument and result positions, admission conditions, application, and realization; cite a FormalSubstrate signature only when that named dependency is current.
Carry an encountered distinction toward later workUse E.18.1 for the carry-through relation.

The same independently identified formal object or episteme can participate in these different uses while retaining its own identity and kind. State the applicable declaration, dependency, operation, lens, or carry-through relation for the receiving use.

For a PrincipleFrame, write one postulate or invariant together with the observable difference that would count for or against it. Cite a characteristic, measurement, unit, scale, reference plane, comparator, or normalization declaration only when that declaration is needed to state or check that difference; an informative citation is not a dependency. Do not put an operation-admission, run-acceptance, or gate-passage verdict into the frame. For ordinary reuse, apply the frame’s Applicability and the direct subject rules for any reference-plane or model-use-structure question. If the receiving claim needs an exact semantic relation between two local senses whose interpretation bases differ, recover the two exact F.17 local senses and test the direct F.9 predicate; cite a Bridge only when it obtains, state preservation and loss in a separate bounded-use claim, and establish any required reliance before use. A cited declaration may be superseded, or an independently obtaining dependency relation may cease or be replaced, without retroactively changing the PrincipleFrame’s identity. Changing the PrincipleFrame’s own citation or dependency claim changes its claim content and therefore identifies another episteme; the same follows when its exact EntityOfConcern or effective reference scheme changes. Any edition, refinement, or supersession relation between the two epistemes must independently obtain and must pass the Vocabulary-Laws-Applicability comparison above.
