The MR !9 changes confirmed by GPT-5: (1) Operation order B→A→C (corrects sequencing), (2) Felt-normality threshold ≥7 (safety floor), (3) Clarity threshold ≥8 (comprehension guard), (4) General abort rule: dominance ≥4/5 on two consecutive checks (prevents single-observation false positives). These four deltas span three operative LSP files with +88 lines total. The abort rule is the most significant: it transforms a single-check gate into a persistence-required gate, reducing false-abort probability substantially.
