Description

NeUQI's per-group asymmetric scale grid search (scale_grid = linspace(0.5, 1.0, 100) × base_scale) failed standalone (mean DC bias propagates as systematic activation offset), but as the inner per-tile step inside gptq_turbo it may compose with FWHT preconditioning the same way E8 does
