A.1.1:4.3 - Identify continuity through model use

At one observation time, the structure has the four A.22 discriminators:

1. exact independently identified constituents—the selected model episteme and admitted model-use holons;
2. exact selected obtaining applicability, use, and coherence occurrences;
3. exact applied constraint claims used by this selection, each with a recoverable proposition and C.2.1 identity; a claim may refer to one U.ClaimScope or its membership predicate, but the bare scope, membership outcome, boundary display, or carrier is not this discriminator; and
4. one exact named selection-use frame containing its question, admissible action, and stop or return condition. An optional explanatory guard follows F.19:4 and remains outside those four discriminators.

No crossing or proposed six-part crossing record enters those discriminators.

At a later observation time, reidentify the same structure only when every continuing constituent is reidentified under its direct rule; any replacement model is connected by exact C.2.1 EpistemeEditionRelation and admitted by the declared continuity rule; every continuing relation occurrence retains its direct identity; every replacement occurrence is explicitly admitted; and all four A.22 discriminators remain the same under that rule.

The continuity rule therefore compares the exact constituents, selected occurrence organization, exact applied constraint claims, and the complete question/action/stop-or-return selection-use frame. A changed constraint proposition reopens the third discriminator; changing only a membership assertion, boundary rendering, carrier, or evidence about an unchanged constraint claim does not. A changed question, action, or return condition reopens structure identity even when every substrate and relation occurrence remains unchanged. A changed explanatory guard alone reopens the affected use claim, not structure identity. If its changed content alters an applied constraint, question, action, or stop or return condition, compare that existing discriminator. A changed page, wording, rendering, carrier, description edition, or publication does not. File history, edition labels, publication order, a shared name, or membership in an edition collection establishes neither EpistemeEditionRelation nor bounded-model-use continuity; A.14 governs any separately selected collection of editions.

Missing evidence creates uncertainty about a continuity claim; it does not by itself end a world-side relation or structure. Any selected substrate holon may separately participate in a larger whole under A.14 and C.13; that is not parthood of BoundedModelUseStructure.
