C.20:4.4 - Identity, continuity, and change
The discipline’s identity is not the extensional part list. It is the exact candidate with its field boundary, practice-and-knowledge assembly principle, obtaining constructive relations, whole-forming architecture, and declared whole characteristic under one direct reidentification rule.
The same discipline may continue through a permitted canon revision, method replacement, institutional change, publication change, or temporary part-relation change when the rule admits that variation and the field boundary, required contribution meanings, essential couplings, and whole characteristic remain within their declared continuity conditions. The rule must say which substitutions are permitted and how the replacement contribution reconnects to the assembly.
A change outside those conditions identifies another candidate or leaves the stronger claim unresolved. When a receiving use asks whether the old whole can still explain the case, run B.2’s existing-whole explanation check after the direct C.20 facts are recovered. Loss of evidence, another description edition, a renamed field, or a stale registry entry does not itself end or create a discipline.
“Discipline edition” is therefore not one automatic object. Recover the changed subject:
- revised canon, standard, method description, classification assertion, or discipline description is another C.2.1 episteme when its identity discriminator changes, with historical continuation tested separately;
- a newly available edition has its own E.24.PUB publication occurrence, form, carrier, audience, use, and availability interval;
- an unchanged discipline during a proper interval may be described through the direct temporal and A.14 phase route;
- a changed field assembly outside the reidentification rule requires another discipline candidate, not a renamed description.
Keep the change rationale as claim content of one exact C.2.1-identified revision or decision episteme. When historical continuation is asserted, the assertion about the exact EpistemeEditionRelation cites the exact source use, applicable continuity policy or rule, and the preserved and deliberately changed claim, EntityOfConcern, and scheme features that the rule consumes. Revision Work, Method, provenance, change facts, and evidence are case facts; no label establishes continuity. When availability changes, trace the publication transition through the ending and beginning E.24.PUB occurrences with their selected edition, audience, bounded use, form, carrier, and availability intervals. The rationale, edition-relation assertion, publication occurrences, and discipline reidentification result remain distinct; none decides another merely by being recorded.
