Re-run post-fix with --grounded-b reverses the verdict: stage 3's full-3D unmask is a clear regression from stage 2, not an improvement. Not retried via the normal flag-retry mechanism \u2014 see stage_index 4 (aggression), which redirects around this branch by resuming from curric-s2-defend directly instead."
