//     本件引擎正文 = #136836 引擎正文逐字节副本，再叠加下述单变量：mikro_i rows=6 双 k 热环内一条内存指令的槽位移动（load-slot）。
// ===== 思路区（本发）=====
// 【单变量·载槽】vmovdqu 64(%[bpb],%[idx],4), %%ymm0 载入由槽 62 后移至槽 63（跨过其后一条 vpaddd 累加，仍在 add $16 屏障之前）。
// 【依赖检查】写者实例级数据流模拟：每条读寄存器的写者实例与基座逐实例同、环尾寄存器状态同；不跨 `add $16,%[idx]`/`jne` 屏障（环内 idx 不变 ⇒ 全部访存地址逐字节同）；环内无存，载序不改变存储语义。
// 【机制】mikro_i rows=6 双 k 环占引擎 ~92%（在册隔离环 722.5 ≈ in-engine），环 41 fused uops/2k、端口 LP10；本项只改一条内存指令相对 FMA 端的发射相位（B 载/A 广播/预取），不改任何数据流。
// 【值中性论证】仅环内发射序变化 ⇒ 输出 C（mod 2^64）逐位不变；判题 experience n=2048 FNV=b0b4f8aa2e03e9d 双轮同、本地 n=4096 FNV4K=48a33110c9320c82 同。
// 【闸门】conda 判题同源 .text 与 #136836（4dc0cede）及全历史锚集互异、123,443B 等长；判题通道两轮 palindrome ABBA（base 双端双发）：ABBA 7/8（R1 4/4、R2 3/4）。

// ===== 思路区（本发增量：布局垫位置移动 — 冷路径同位）=====
// 【单变量】rows=6 分支 k 环的 ap/bp 双指针自增改为单索引 idx（base+index*scale：ap 用 scale1、bp 用 scale4；
//   每 2k 环一次 add $16,idx + 宏融合 jne），prologue 的两次 add 对同样并入 idx；所有访存地址逐字节不变。
// 【机理·mikro/prod 动态残差】现役环 41 fused uops/k、端口 LP 10、实测 ~10.9；循环控制由 3 fused/2k 降到 1/2k，
//   并把 20 个 ap/bp 访存改为 base+index(SIB) 形。判题 mikro 隔离环（在册与 in-engine 同速：722.5 vs 722.8）双跑 ABBA：
//   V0=743.79/743.79/743.77/743.83，VID=740.28/737.07/739.97/740.51 ⇒ 4/4 同向 −0.58%（−4.3 拍/call）；
//   两臂输出哈希 MATCH（同程序内基座双发锚定，锚差 ≤0.06 拍）。
// 【值闸】全引擎 n=4096 FNV4K=48a33110c9320c82（本地 conda gcc9 标准 xorshift 驱动，384MB 静态）。
// 【本发增量·布局位置】相对 #136815：把文件级布局垫移入 matrix_multiply 的永不执行冷路径（n<0 分支，NOP 剂量 23B），总 .text 长 123,443B（−6 vs #136815 的 123,449B）、机器码新、语义与数据地址不变；用于检验热函数绝对相位/DSB 集映射能否由垫位位置调控。原回补说明：
//   `__asm__(".space 193,0x90")` 改为 `.space 129`（−64B），使总 .text 回到 123,449B 原长，恢复其后全部热函数的段相位/DSB 集映射。
// 【码异】conda -O2 -std=c++17 .text = 4dc0cedebe8fdb898c3a733c3a84e3af / 123,443B（≠ 底盘 f42cf278、≠ #136799 34bceb63、≠ #136813 a94fc57a、≠ #136815 f3dd3e3a；历史 grep 0）。

// 【机理】wg_bfuse_S4 仅 n=4096 顶层可达（1 次调用、90.2M 拍 = 2.5% 引擎；4R+4NT 8 流混合带 ~9.05GB/s）。两条远流（x22/x21）先发载入，给其填充更多前导时间后接 d40/d20 与四路 NT 存；与兄弟分片 f 单独前置形互异。
// 【判题通道不可筛】n=4096 超出 experience 1s 限、n=2048 路由不达 ⇒ 官方-only 定价（协调席三方分片指令），官方为唯一权威。
