Experimental research artifact. Base: Qwen/Qwen3-4B-Instruct-2507. SFT on rasbt/math_distill Qwen3-235B-A22B math traces (procedural ≤4000-tok filter). Named -SFT, not -Distill — we SFT'd on a public teacher-trace dataset; we did not run the distillation ourselves.

Eval (MATH-500, 500 anchors): accuracy 325/500 = 0.650; has_think_block 500/500.
