It also computed q8[j+16..j+32] as _hsum_hi and dropped it, so block is's min term missed 16 values. fused_q4k_q8k_dot_with_bsums_avx2 carries the same pairing. The bsums dispatcher has NO AVX-512 branch and fused_q4k_q8k_ffn_up_gate_into (the Q8K FFN up/gate projection, gguf/inference/forward/results.rs) calls it per row, so the pairing reached CPU inference on every x86 box; the plain dispatcher reached it only on AVX2-only CPUs (yoga, Core Ultra 9 185H, 2026-09-10: rel_err 2.6% on the existing parity test). Falsifier: FALSIFY-QDOT-006 calls each kernel DIRECTLY on super-blocks whose 8 scales and 8 mins all differ, on every box that can run it (tol 1e-3 rel). Reverting either fix turns it red: -3650.1 (plain) / -3329.5 (bsums) against scalar -25161.5. With both: 145 Q4K x Q8K tests pass on lambda (Threadripper 7960X), including the VNNI path's direct test.

Measured on Qwen3.5-0.8B-Q4_K_M, whose attn_qkv and ssm_out are Q5_K: realizar disagreed with gguf-py on 5,959,751 of 6,291,456 values of blk.0.attn_qkv, and the layer-0 QKV sum was +26.64 against llama.cpp's -17.06. With this change it is -17.0967, and layers 0-2 of the #3091 trace match llama.cpp. Nothing caught it because every Q5_K test compared one aprender reader with another. realizar's dequantizer and fused dot now share a single block walker, so they cannot drift apart again. FALSIFY-QDOT-009 pins both readers to the 256 values that gguf-py (llama.cpp's own reader) produced from a block llama.cpp quantized. A round-trip on data whose sub-blocks all differ pins the packer to that reader; the old ramp round-trip gives every sub-block the same codes, and a packer that swapped sub-blocks survived it. Reverting either reader or the packer turns the tests red. The CUDA Q5_K gemv and gemm kernels carry two more wrong layouts. They get a separate PR.

Comparing each op against llama-eval-callback's dump (the sum of every graph node, layer 0 and then layer 3) located eight defects in this file: 1. q/k L2 norm ran over all heads at once, and twice. llama.cpp normalises each head (build_gdn_l2_norm), now l2_norm_per_head. 2. The DeltaNet path applied RoPE. llama.cpp's applies none; position comes from the causal conv. 3. Attention RoPE rotated the full head width, GPT-J style. llama.cpp uses partial NEOX, n_rot = 2*sum(rope sections) = 64 of 256 (now apply_partial_neox_rope). 4. The DeltaNet output got a stray global L2 norm. 5. beta went through sigmoid twice. 6. The conv output went through SiLU twice. 7. The attention output gate (attn * sigmoid(gate) before o_proj) was never applied. It is now apply_sigmoid_gate. 8. The attention head width was hidden/heads (128). Qwen3.5 uses key_length (256), so the KV cache and the score loop read the wrong slices. The ninth defect sits outside this file: Q5_K weights decoded to other numbers. It is fixed in #3110, which is merged under this branch. After these fixes every layer-0 and layer-3 op is within 1-2% of llama.cpp's sums (llama.cpp's CPU matmuls quantise activations to Q8_K). Teacher-forced decoding agrees with llama.cpp on 66 of 68 steps. Both misses are near-ties: llama.cpp's token is realizar's rank 2, with gaps of 0.145 and 0.185 logits. The F32 tensor loader reinterpreted mmap bytes with an unsafe align_to and panicked on a type mismatch. It now decodes the bytes and returns an error. The public surface is Qwen35Model {create_base_model, from_model_and_layers, new_state, forward_single_qwen35} plus run_qwen35_generate. The layer types and all fields are pub(crate), and the dead GDN RoPE helper is gone. The base model now initialises the CUDA-only fields, so the file builds under `--features cuda` (the lane's literal did not compile there). The module is a #[path] module with documented items, not an include! behind allow(missing_docs). Unit tests pin per-head L2, the sigmoid gate and partial NEOX RoPE; reverting either per-head L2 or the NEOX half turns them red.

For each prompt it records the free-running greedy divergence and a teacher-forced comparison. The gate: at every teacher-forced step, llama.cpp's token must be realizar's argmax, or realizar's rank 2 within QWEN35_PARITY_TAU (default 0.25) logits. Between two backends with different accumulation precision, exact greedy equality is a coin flip at a near-tie (#2359). Every gap is written to parity.json.
