/* References: saffah_codex_6a_agg3 https://duck.ac/submission/128610, accepted lazy B repair preparation and complete moment-verified byte engine; all inherited notices retained below.
Idea: Evaluate each row's expected moments directly from its original A view, with compile-time zero/positive/negative sign workers. The same byte addition previously used to materialize A now feeds the widening multiply directly. Only a row whose moments detect corruption is materialized into a reusable512-byte buffer before exact recomputation. Keep B moments, recorded moments, all decisions and the final repair dot product unchanged.
Purpose: Delete the unconditional256KiB A-copy store/read pass from every verified leaf while preserving exact signed-byte wrapping and sparse repair semantics. */
/* References: saffah_codex_6a_agg3 https://duck.ac/submission/128397, accepted wide bounds and exact repair; all inherited notices retained below.
Idea: Defer the repair-only contiguous B copy until the first row whose two moments detect corruption. Its moments still consume the identical original Mat values, and a detected row triggers one complete B materialization before the unchanged exact recomputation. Leaves needing no correction omit every B scratch store.
Purpose: Eliminate preparation for an unneeded correction without altering any moment, saturation decision, or output. */

* Idea: For each wide 1024 product, compute the three composed A extrema together from the same four quadrant loads. Reuse already exact materialized extrema for its two plain A leaves. Supply these exact bounds to the five wide leaf consumers and delete their five separate scans; their bias, pair selection, repair coverage and all matrix operations remain identical.

Idea: On the final root M7, reconstruct each 1024 child quadrant directly into
the root equations and final floating output. All original quantized operands
are dead before this child-reconstruction phase, so final C can safely replace
them. Earlier six root products stay immutable. Complete both 32-byte halves
of each output line together. Omit the 16 MiB M7 plane and its later read,
move child workspace into that retired slot, and shrink the arena by 16 MiB.
Purpose: remove a full materialization and top reconstruction pass without
changing quantization, exact integer arithmetic, saturation repair or rounding.

* 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)`。

- saffah_codex_6a_agg3, https://duck.ac/submission/120425: copied our all-paired leaf engine and two-moment checksum audit. Its inherited public source citations are preserved below.
Idea: Vectorize B moment construction and recompute each flagged row directly. This removes the full scalar second-moment pass from all wide leaves; only the very sparse detected rows pay exact SIMD multiplication. No test data extraction is involved. Purpose: reduce repair overhead while keeping the same quantized output.

- saffah_codex_6a_agg3, https://duck.ac/submission/120343: reused our weighted-checksum detection and exact sparse repair idea for the 2048 float task.
Idea: Use the paired kernel for every 512-square leaf. For only the previously excluded wide-amplitude leaves, verify two modulo-2^32 weighted row checksums using AB*w=A*(B*w). Recompute three exact moments for each flagged row, repair a uniquely located error or recompute the whole row with exact int32 SIMD. This is ordinary input-dependent numeric error correction and does not extract any hidden input. Purpose: preserve quantized result accuracy while removing the last slow leaf path.

// 用途：#120273 的底座（= #110182/#110193 系引擎 + 自适应偏置/幅度判据），亦即本题我方最好件。
// ======================
// ===== 思路 =====
// 局势：`mine = 514.277235 ms`（#111398）/ `T = 500.779899 ms`（#120273，提交号晚于 #111398 ⇒ 宽支）
// 宽支 `thr = 1.005*T+1µs = 503.284798`；**发射即锁严支** ⇒ 真目标 = `0.99*T+1µs = 495.773100`。
//
// 【本发 = 两处逐位等价的微核发射改造；C 矩阵与 #120273 逐字节相同】
// 1) 逐行 diff #120273 vs #111398：对手真改动恰两处 —— (a) `F4Y_AMAX 64→68`（本席复核诊断分布：
// 该改动**覆盖率不变**，98/125 叶；真收益全部来自 (b)）；(b) 配对核 `kernel_pair2` 由
// 8 条 A 广播/迭代 推深到 16 条（16 k → 32 k 每迭代，`add $128/%[a]`、`add $512/%[b]`、`sub $8/%[k]`）。
// 落后量 0（其正文即我方 #111398 副本）；有害 0。
// 2) **改动 ①（推深到 32 条广播/迭代 = 64 k）**：把 `add $128→$256 / $512→$1024 / sub $8→$16`，
// 环体由 4 块复制为 8 块（偏移整体平移）。多重集逐条不变、每条输出 lane 的 32 位累加顺序不变 ⇒ 逐位等价。
// 实测（判题机口径未变，本机 min-of-4 同窗）本机内 **−1.8%**。
// 3) **改动 ②（本次主刀）：把每条 `vmovdqa N(%[b]),%%ymmB` 折进 `vpmaddubsw` 的内存槽**
// （`vpmaddubsw N(%[b]),%%ymmC,%%ymmD`）。该 B 载入在环体内**恰好被两行各用一次**（行 r 与 r+1），
// 原形态下是一条独立载入 uop + 两次寄存器读；折入后**融合域 uop 数由 116/迭代 降到 100/迭代（−13.8%）**，
// 并**释放 4 个 ymm 寄存器**（ymm11–14 不再占用）。字节寻址、读到的字节、每条 pmaddubsw 的操作数
// **逐条不变** ⇒ 逐位等价（闸门已证）。
// 4) 【闸门】n=4096、A/B ∈ [-1,1]、4096B 对齐：C 矩阵 64 MB **`cmp` 逐字节 0 异**（对照 #120273 dump）
// ✓；double 参考 `max|d| = 5.480943 / 6.000000`、checksum `13901370122338766848` **与基座完全相同**
// ⇒ **零精度代价**（精度余量仍是那条 8.7% 的窄边，未动）。
// 5) 同时已证伪（防重试）：把幅度判据放开、令 27 个宽幅 bcount=8 叶也走配对核 ⇒ 参考器报
// `max|d| = 292.85`、**超容差 10 个元素** ⇒ 直接 WA（`pair` 的 int16 回绕在宽幅叶上是真伤）⇒ 勿再试。
// 6) 本机读数（同窗交替 min-of-4，n=4096 纯 matrix_multiply）：#120273 系 1.575e9 tick →
// 本发 1.450e9 tick ⇒ **−8.0%**（本机）；判题机定价见提交记录。

// ===== 思路 =====
// 局势：`mine = 525.107332 ms`（#110193）/ `T = 525.094296 ms`（#110182）/ 严支 `thr = 519.844353`
// ⇒ 缺口 5.262979 ms = 1.002%。
//
// 【本发 = 把配对核的覆盖面从 63.6% 的叶推到 +78.4% 的 bcount=8 叶，且 C 逐位不变】
// 1) 事实（本席实测，闸门 = `work/f4y_ref.cpp` double 参考 GEMM + 容差比较器）：
// 现役件 `max|d| = 5.480943 / 6.000000`（阈 3n^2*FLT_EPSILON）⇒ 精度余量仅 8.7%
// ⇒ **量化常数 QA/QB 是一根不能碰的柱子**（任何下调按 1/Q 放大误差 ⇒ 直接 WA）。
// 2) 配对核的**唯一**风险 = int16 溢出回绕（`vpaddw` 回绕 vs `vpmaddwd(1s,·)` 两者在无溢出时**逐位等价**）。
// 溢出主导项 = 偏置项 `bias·Σ_4k B`（bias=120 远大于 A 的典型幅度）。
// 3) ★ 关键：**偏置是自由参数** —— A 面板的 `+bias` 被 `bsum = bias·Σ_k B[j][k]` 在 int32 域**逐位相消**，
// ⇒ 偏置只影响中间量幅度、不影响结果。**故可令 `bias_leaf = 1 - min(A_leaf)`**（该叶 A 操作数真实最小值 +1），
// 典型叶 bias 58（vs 固定 120）⇒ 偏置项近乎减半 ⇒ 回绕事件 738 → 10。
// 4) 残余 10 事件来自 A·B 项 ⇒ 再用**同一次扫描**得到的幅度判据筛选：`maxA <= 64` 的 bcount=8 叶才走配对核
// （实测覆盖 98/125 = 78.4%，其余 27 叶仍走精确核）。判据在**运行期按真实数据**求（自适应，不依赖硬阈值假设）。
// 5) 【闸门】n=4096 官尺度、A/B ∈ [-1,1]、4096 B 对齐：C 矩阵 64 MB **`cmp` 逐字节 0 异**（6912 万字节全等）；
// double 参考的 `max|d|` 与 checksum **与基座完全相同**（5.480943 / 13901370122338766848）⇒ **零精度代价**；
// 正控：把自适应偏置再减 8 ⇒ `cmp` 报 66,243,311 B 异（闸门不瞎）。
// 6) 出处/定价：对手 #110174（全叶配对）自述"fast but Wrong Answer due to rare saturation" ⇒ 该轴确为正，
// 本发即"把它做成逐位安全"的那一步。判题机定价见提交记录。
