E.11.PUR:4.2.1 - Reuse an earlier result when it still answers the concern
After identifying an applicable candidate use, ask whether an earlier result episteme already answers the present concern. Use the pattern that defines or tests that result to compare:
- the result episteme’s
EntityOfConcernand edition; - the question answered and declared use;
- the source and dependency conditions on which the answer relies; and
- its qualification and currentness boundary.
When those values still match, cite and use the earlier result. Use A.10 when a named claim or bounded action relies on that result and the source-to-use account is still implicit. Add a dated U.Work occurrence only when that Work is itself a current claim. Use G.11 when currentness or refresh changes the use. Stop without repeating the same pattern use or copying the result under another stage name.
When one value changed, reopen the smallest affected result question under the pattern that defines or tests that result. Repeat the complete pattern use only when the unaffected reach cannot be established. If the applicable pattern supplies no basis for comparing the earlier result with the present concern, stop at insufficient result-comparison basis.
The candidate pattern use, the earlier result episteme, a later reliance relation, a currentness assertion, and later Work remain separate. This branch introduces no generic result-reuse relation.
