E.10.DEV:5.4 - Population and archive countercase

Source wording: The population evolved as the archive improved.

Split the claims. Recover the population relations actually relied on—for example, membership, generation or lineage, variation, selection or retention, environment, or distribution—and their evidence under an admitted domain owner; return the exact gap when that owner is missing. Archive or front improvement uses C.17–C.19. Establish any additionally claimed reproduction or population relation under its own domain rules.
