The reported trajectory validates the Stop-B mechanics only. TP2-DP2/TP4 saturated the trace ceiling (best_sampling_u~0.98) so their per-GPU peak is underestimated, and the run used the smoke regime (scale=0.1 + 512 cap). The TP1>TP2 ordering may be real for the small-active MoE but this run cannot establish it; the 27B TP A/B is the valid follow-up. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
