F.15:11.1 - Schemes, versions, and known confusions

RSCR-F15-E1 (Exact before/after and no silent replacement). For each changed member, resolve exact @t0 and @t1 refs and versions. A changed effective ReferenceScheme changes interpretation-bearing content; an unchanged label or shared designator does not prove continuity. State the exact identity, continuity, split, retirement, or replacement claim and cite the rule that defines or tests it.

RSCR-F15-E2 (Known confusion check). Recheck or explicitly retire every prior confusion, blocked use, and nearest counterexample affected by the change. A new edition does not erase an old trap.
