| rank | ablation | bpt_gap | top1_agree | student_bpt | teacher_bpt | ARC-E | HSwag | corpus | knob delta |

Ranking: lower `bpt_gap` = less compression damage. On the `nemotron` corpus the gap is RELATIVE (Stage-2.5 adaptation is common-mode across rows) — rank rows against each other, not against zero. Tiebreak: higher `top1_agree`, then ARC-E+HSwag.
