E.17.EFP:4.5.d. Composition and reopen rule

Repeated SourcePinnedExplanation over forms of the same exact source edition can be idempotent for the same bounded use. A changed selection of content reopens sufficiency for that use; changed assertions, concern or effective scheme reopen C.2.1 identity and any source-to-target relation. Didactic target forms reopen when their target edition, relation or use changes; speculative forms reopen when their B.5.2 hypothesis edition, prompt relation or exploratory use changes.
