nx_gen_prenorm_mod_verify.nx

nx_gen_prenorm_mod_verify.nx -- SOVEREIGN DiT pre-norm + adaLN modulate, verified vs the oracle. y[t][i] = ( x[t][i] / sqrt(mean_i(x[t]^2) + eps) * w[i] ) * (1 + scale[i]) This is the entry half of every modulated DiT block: RMSNorm, then scale-modulation broadcast from one chunk of the adaLN vector. Z-Image, Flux and SD3/MMDiT all use this shape; only the chunk COUNT and INDEX differ, so both are arguments. Usage: nx_gen_prenorm_mod_verify <model> <x> <norm_w> <adaln> <n_chunks> <scale_idx> <y> [rows] [eps_recip] It is a TWO-op composite on purpose. RMSNorm is already verified standalone by nx_gen_rmsnorm_verify, so if this organ is RED while that one is GREEN the fault is isolated to the modulate half or to the chunk index -- which is the only reason a composite is acceptable here rather than a fixture for the intermediate. Hardware __f32_* intrinsics in the hot loop, never the nx_f32_* software twins. license_tier: ORIGINAL
