# Mirror of Run 6's d24+ratio=8 strategy from the other side of compute-optimal — d22 is below GPT-2 capability,
# so we overtrain rather than undertrain. Combined with --warmdown-ratio=0.85 (longer low-LR tail) and
# --muon-qk-clip-tau=100 (Kimi K2 §A QK-Clip) the recipe crosses GPT-2 CORE in 3.3% less wall-clock than Run 6.
