Idea: Build each B row's two256-column prefix streams independently. Concatenate their zeroth sums and add32 times the upper-half sum to the combined first prefix, then recover exactly the original column weights. Reduce the vectors directly in registers. This halves the longest prefix dependency chain while keeping every B byte and both checksums identical.
Purpose: Improve exact repair screening throughput without changing error detection or repair arithmetic.

Idea: Adapt split16-bit exact moment products to signed A bytes and512-square repair leaves. PMADDWD processes16 coordinates per operation, replacing eight-coordinate32-bit multiplies. If all zeroth moments fit int16, skip their identically zero high-part stream. Compute each pair of expectations directly before checking its output row, removing the intermediate expected arrays; full-width row repair remains unchanged.
Purpose: Reduce checksum verification arithmetic while preserving every exact modulo32-bit comparison and repaired output.

Idea: Use the smallest nonnegative bias that makes every A byte unsigned,
allowing the minimum to map to zero. Compensating B column sums still cancel
the bias exactly. Apply the exact eight-product int16 bound4095 instead of
the inherited rounded-down4000 bound when choosing the four-pair kernel.

Idea: Recompute flagged rows with four SIMD accumulators holding32 columns.
Sign-extend adjacent B rows, interleave corresponding columns, then use
paired signed-word multiply-add. Restore column order only at final store.
This preserves exact modulo32 arithmetic while eliminating C traffic within K.
Experiment purpose: Combine bounded P4 selection with less expensive exact repair.

* 【三处改动，逐位等价】
* ① `materialize1024` 物化 1024x1024 平面时**顺带**统计 4 个 512x512 象限的 int8 极值（复用同一批 ymm，
* 零额外访存）。叶面板 = ma/mb 的象限及其 ± 组合 ⇒ 由此得到叶级 maxA/maxB 与自适应偏置的**保守上界**：
* 组合的 min 不是 min 之和（实测保守值比精确扫描宽 ~19），故 amn ≤ 真 mn、amx ≥ 真 mx
* ⇒ P=4 判据方向正确（只是偏保守）；偏置仍被 bsum 逐位相消，C 不变。
* ② P=4 判据（8·maxA·maxB ≤ 32767，等价于 int16 四路树无回绕）现对**全部 343 叶**求值 ——
* bc ≤ 4 叶直接用 ① 的保守极值（**不再扫描 A/B**），bc = 8 叶仍走**精确 32 B 宽 A 扫描**
* （`use_pair = mn+68 ≥ 0` 需要精确 mn；改用保守值会误翻 ~53 叶去 repair，实测不划算）。
* 覆盖叶数 32 → **64**（本机逐叶枚举证：保守极值与精确扫描给出同一 64 叶）。
* 收益：bc ≤ 2 叶原有的 A/B 双扫描（68 叶）与 bc = 8 叶的 16 B 扫描全部消失，扫描相位 3694 → ~1100 µs。
* ③ P=4 叶按判据已保证无 int16 回绕 ⇒ 该叶 C 精确，pair2 的前缀矩量与 repair_leaf 对它纯属冤枉账
* （实测：不关会多报 191 行整行重算，白花 3.8 ms）⇒ `need_rep = (!use_pair) && (!use_p4)`。
