E.15:4.8 - Edition continuity and stop rule

Keep accepted historical editions immutable and recoverable. A successor does not rewrite what an earlier edition meant. A source-edition change reopens only claims and actions that relied on the changed source value; unchanged exact inputs and unaffected premises remain reusable.

E.15 finishes when the candidate answers the change question, every actual dependent locus in scope is repaired or explicitly unresolved, material predecessor functions have dispositions, and the selected checks support the claimed Delta-Class and continuity. Publication, acceptance, registration, and landing remain separate later decisions.

Schedule a living refresh only for a high-value claim likely to change and only when someone will use the signal. Name the trigger and affected claim. Otherwise use ordinary periodic review; a generic “watch SoTA” obligation is not useful work.
