Optimized MLX decode: one-big-function @mx.compile (48 layers), zmlx moe_mlp patch with sigmoid gating fix (zmlx defaults to softmax, Laguna uses sigmoid), precomputed attention masks, bfloat16 gating. Pure MLX, no torch/CUDA. Quality: 0.9555 Pearson logit correlation vs BF16 reference. Code: github.com/jacklarmer/laguna-apple
