Four topics need a scope re-check before verdicts are final. These test sets predate the 2026-10-14 wave-2 restructure and need a scope re-check against the new topic compositions before verdicts are final (U2 topics 3/4 swapped scopes; U1's MPM-033 moved from topic 2 to topic 3; nine U2 lesson ids were retired).
