nx_f32_dit_block_tiny.nx

nx_f32_dit_block_tiny.nx -- first sovereign f32 DiT (Diffusion Transformer) BLOCK, assembled from the gated bricks. The repeating unit of the Z-Image diffusion backbone (Peebles&Xie 2023 DiT; adaLN-Zero). sd-server -> Nishi migration milestone (the DiT half's analogue of nx_f32_vae_decode_tiny). Per token: x1 = x + gate1 * Wo @ Attention( Wq,Wk,Wv @ adaLN_mod( RMSNorm(x), scale1, shift1 ) ) out = x1 + gate2 * SwiGLU( adaLN_mod( RMSNorm(x1), scale2, shift2 ) ) Composes the gated organs: nx_f32_rmsnorm + nx_f32_adaln (modulate + gated residual) + nx_f32_attention + nx_f32_silu (in the inline SwiGLU) + inline linear projections. Single head v1 (head_dim = D). The adaLN scale/shift/gate come from the conditioning MLP (caller-supplied; adaLN-Zero starts gate=0 => identity). x,out: flat *i64 f32 bits [n_tokens, D]. W{q,k,v,o}: [D,D]. SwiGLU W1,W3: [d_ff,D], W2: [D,d_ff]. sc/sh/gt{1,2}: [D]. gamma: [D] (RMSNorm scale). Scratch is allocated internally (fork-per-use organ). license_tier: ORIGINAL
