about

nx_zimage_ffn_down_verify.nx -- SOVEREIGN Z-Image FFN sub-piece c (final): down-proj + norm + gate + residual. ff = ffh @ w2.T ; ff = rmsnorm(ff, fn2) * tanh(gl) ; out = ff + x_after_attn. Verifies vs oracle `out`. tanh built from exp (sign-stable). ff[] is a per-token local scratch. license_tier: ORIGINAL
