// [1] duck.ac 用户 pdoom，提交 #86352 <https://duck.ac/submission/86352>
// 用途：本题源码整体直接复制自该提交（problems/mmms4k/ref/01_pdoom_86352.cpp），
// 包括：Strassen-Winograd（7 乘 15 加、Z/2^16 精确）递归结构、递归四象限 packing、
// BASE=64、4 行 x 24 列 AVX2 微内核（vpbroadcastd 广播 32 位 (A[i][k],A[i][k+1])、
// B panel k/k+1 两行 16 位交错、vpmaddwd+vpaddd），以及 combine/base/unpack 的实现。
// [2] duck.ac 用户 saffah_cc_v41_260924，提交 #96771 <https://duck.ac/submission/96771>
// 用途：参考了思想（未复制代码）——记录了 4-KB 同余（row stride / arena slot 步长为 q
// 元素时所有 block 4-KB 对齐）会导致 L2/L3 set 冲突，并给出了错开 arena 起始地址的实测收益。
// [4] duck.ac 用户 saffah_codex_6s_agg2，提交 #102935 <https://duck.ac/submission/102935>
// 用途：直接复制了 micro24 / micro16 两个微内核内层循环里 vpmaddwd 的指令次序
// （把每条 (row,k-pair) 的第三个 vpmaddwd 上提早一格、并让它的目的寄存器复用广播寄存器
// ymm14，而不是 temp ymm15）。该次序经判题机实测比原次序快，故本提交沿用。
// 我方基座为其上一条 #97603 <https://duck.ac/submission/97603>（本账号自己的提交）。
// ======================
// ===== 思路 =====
// 本提交 = 我方 #97603（pdoom #86352 + 数组错位 + unpack 非临时存储）之上，做两件事：
// 1) 采用 [4] 的 micro24/micro16 内层指令次序（单变量 probe 实测 -2.83 ms，
// -0.43%，与该账号在榜单上的 -0.61% 同号同量级）。
// 2) 【本次新刀】把每个 base-case 微内核调用的第一组 k-pair「剥皮」(peel)：
// 原来每次调用都要先用 12 条 vpxor 把 12 个累加器清零，再在循环首轮用
// vpmaddwd->ymm15; vpaddd ymm15,acc,acc 两步累加。现在把首组 k-pair 展开到循环外，
// 让它的 12 条 vpmaddwd 直接写进累加器（首轮不再需要清零、也不再需要 vpaddd），
// 循环体本身不变（仍按 a+=64B / b+=384B 推进）。每次调用省 12 条 vpxor + 12 条 vpaddd；
// n=4096 时共有 5.6e6 次这样的调用（117649 个 64x64 叶子 x 48 次调用）。
// 注意只剥「第一组 k-pair」——若把整轮 4 组 k-pair 都改成直写累加器，后 3 组会覆盖
// 而不是累加，答案就错了（本地逐字节对拍会立刻发现，本次已避开）。
// 单独定价：去掉 12 条 vpxor = -3.0 ms（probe）；剥皮（含首轮 vpaddd）= -8.5 ms。
// 实测（立即体验，同 harness，2 次取 min）：
// 基线 #97603 源 = 660.84 ms；+[4] 次序 = 658.11 ms；+[4]+剥皮 = 649.45 ms（-1.72%）。
// 本次提交目的：把已实测的 -1.72% 落到榜单成绩；并验证 probe 结论在正式评测上同号。
// 本地正确性：与 #97603 逐元素输出一致（C 对角线 FNV 校验和 18446744073708248500 相同）。
