pub static ROUTER_W8_DEFAULT: AtomicBoolExpand description
Per-model router-GEMV form (2026-07-31): the 8-warp twin is +8.8% on the H100 q35 decode step (router was 14.8% of it) with argmax + spec self-consistency green on qwen-class MoE both rigs. The gemma-4 26B knife-edge block (2026-07-31, single synthetic prompt) was RE-ARBITRATED 2026-08-01 on 6 real prompts — gate outcomes identical to the lone-warp arm, +13% g26 decode — so gemma4 rides the default too (research/g26-decode-20260801/). MEMRA_ROUTER_V2 env overrides either way.
