The overflow decision was rank-local, and the dense rerun has collectives of
its own: one rank rerunning left the others waiting in its all-gather (NRT
'Collective operation pending'). The flag is now max-all-reduced over the EP
group. The bench gave every rank the same prompt, which routes 64 copies of
each token to the same experts (overflow on every layer); real requests
differ, so the prompts now take the rank in their seed.
