M1 drop-out is a no-row Unspecified+IsRestatement update (projector case); M2 ack judged over every declared limit; L1 ActiveAcknowledged for an already-acked new limit; L2 Bad Acked/severity carried/skipped; L3 host end-to-end test; L4 BOOL member-by-member tests + mixed ALMD/ALMA; L5 detection requires no plain Acked. ALMD active bit is InAlarm per Rockwell's ALMD reference; InFaulted is input health. Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
