+trained_from: 'sequence-level KD from the r7 canonical teacher (rababa_arabic_byt5/run-007-news/best,

+  (E4, pre-registered gate <= 6.26). Checkpoint rababa-checkpoints:/rababa_arabic_distill_small/run-007-r7-muon-6ep/best.
+  The two measured wins compound: 8.259 -> 4.8218 full-set windowed DER-CE (teacher
+  reproduces 2.289 in-run vs documented 2.2864) — a 42% error reduction on the 1.0
+  release at the same architecture and artifact size. Still misses the strict teacher+0.5pp
+  gate (+2.53pp; miss disclosed); the E2/E3 factorial attributes the residual to domain
