+**5.784**, paired bootstrap delta 3.2455 [3.033, 3.491], p=0. The

+Muon, 190M) **5.784** -> full (6ep Muon, 300M) 4.5701 -> teacher 2.29.
+Depth cost at 6 epochs: 1.21pp (CIs non-overlapping vs G2a [1.91,
+2.35] - statistically real). Subset said 0.64pp: the FIFTH
+subset-overstatement instance. The lite tier is shippable: 28% smaller
+artifact for 1.21pp; int4 (~95MB) export is the browser-budget item.
