* LICENSE: public duck.ac site submissions (submitted code is published); no external repository code and no
* separate software license stated; all inherited notices retained verbatim below.
* APPROACH/PURPOSE (experimental submission; class: delete work the fixed judge shape makes redundant):
* (A) the 8 KiB parity hand-off copy is deleted: corr_six256 writes straight into its Psave[slot] via Pcur.
* With Defer=true the mikro_u4 leaf compiles its PB parity blocks out, so the same 8192 bytes reach the
* same consumer unchanged. (B) matrix_multiply's n!=2048 path is deleted: the problem fixes n=2048, so
* that code is unreachable and strassen1 is called with the identical arguments.
* Value gate: C bytes identical to #141734 on 7 shapes (4 seeds, all-zero, all-(-128), all-127).

Idea: dispatch the existing256 specializations before the general sign-only early returns. Previously every supported sign tuple returned through a dynamic-size packer before reaching the h==256 branch.

Initialize the eight accumulators directly with the first byte-pair product,
then enter the existing unrolled ring at its second pair; later rings retain
exactly the original order. This removes eight zeroes and eight adds per

// ======================
// ===== 思路 =====
// 【r2m_/mmmc2k 移植席 · 本件 = 对手 #125936 底盘 + 一把刀 `gray12`（c1k → c2k 搬运）】
// A. 搬运前的**三前提核查**（协调者硬门槛 · 结论：成立 ⇒ 可搬）
// ① 任务：同为 int8 矩阵乘、逐元素 mod 2^8；c1k n=1024 / c2k n=2048（同一家族）。
// ② 引擎形态：两边的校正相都是「按叶子尺寸查表 + Gray 分区建表」的同一结构 ——
// c1k `corr4_256`：4 个 64 位字块 × 12 组，建表 = 32~64 条 XOR 级联存
// （Gray 分区），查询 = 每字取 12 个字段；c2k `corr_six256`：4 块 × 11 组，
// 建表同形（r0..r5 级联），查询 = 每字取 10 个 6 位字段 + 1 个 4 位尾巴 = 12 处。
// **掩码几何逐位同形**：63 槽 × 32 B = 0x7e0（gcc 把 `((w>>6g)&63)` 折成
// `(w>>(6g-5)) & 0x7e0`）⇒ c1k 那把刀的距离/掩码公式**逐项可映射**。
// ③ 内存体制：两边该函数都只碰 256×256 叶面板与 ~16-21 KB 查表（L1 常驻），
// 与 n 无关 ⇒ 无面板/工作集差异。
// **判读模板（可复用）**：token 缺席 ≠ 刀缺席。c1k 独有而 c2k 没有的 token
// （`bmi2/lzcnt/popcnt/prefetchw/_mm_prefetch/rename-registers/no-strict-aliasing/
// _mm256_broadcastd_epi32/_mm256_shuffle_epi8/_mm_cvtsi32_si128/1600/2304`）
// 里，多数是「**等价但不同写法**」（c2k 用自己的 `bcast16` 内联汇编、
// 自己的表布局常数），只有 **`bmi2` 这一处是真丢刀**：判题机 gcc 9.3 -O2 的
// 实际码流（godbolt 直取）里 c2k `corr_six256` = **267 条指令 · shr 20 · rorx 0 ·
// and 20 · mov 25**，即 20 处「移动+移位+掩码」三 uop 抽取；这正是 c1k 刀
// 要去掉的那一族。⇒ 只搬这一处、单变量。
// B. **本刀的精确内容（单变量）**：`corr_six256` 内
// · 属性 `AVX2BMI` → `R2M_BMI2 = target("avx2,bmi2")`（rorx 需 BMI2；判题机
// i3-8100 为 Coffee Lake，BMI2 在位；对手自己的 c1k 件已带 rorx）；
// · 查询环 4 处 + 尾巴 2 处的索引：`(w>>6g)&63` 折叠形式改为
// `R2M_ROR(w, 6g-5 mod 64) & 0x7e0`（尾巴 `R2M_ROR(w,55) & 0x1e0`），
// 表基址从 `__m256i*` 换 `char*` + 预算字节偏移（g*2048 / +2048 / TBc+20480）。
// 旋转带入的位全部落在掩码之外 ⇒ **逐位等价**（掩码窗口 [5,10] 恰为字段
// [6g,6g+5] 的像）。建表相、XOR 级联、面板、次序一字未动。
// C. **判题机码流实证（godbolt gcc 9.3 -O2，唯一可信编译器；本地是 gcc 15）**：
// `corr_six256` 改前 **len=267 shr=20 rorx=0 and=20 mov=25** ⇒ 改后
// **len=248 shr=0 rorx=22 and=22 mov=5**（−19 条指令、−20 处三 uop 抽取 →
// 两 uop rorx；immediate 59/1/7/13/19/25/31/37/43/49 与推导一致）。
// ⇒ 纯 ALU 指令数刀（"改指令序列"族，舰队在册传导 ≈1.05×，非 hint 族）。
// D. 值闸门：`r2m_vgate.py mmmc2k cand_gray12.cpp --nsample 500 --blocks 2`
// ⇒ **checked 8692, worst 0, bad=0** ✓（本机 chk 与底盘逐位相同）。
// E. 本机判题机 r0 定价（`r2m_tr.py 2 base gray12`，单次冷调用 `__rdtsc` 包夹

/* New idea: transfer deferred parity to the 2048 engine only in its seven 256-leaf groups. Save each 8192-byte plane, remove four leaf correction expansions, vector-XOR the seven planes per reconstruction row, and expand only four final combined masks. Other leaf call paths keep immediate correction. Purpose: full2048 exact comparison then official evaluation of moving correction out of49 leaf products. */
