// ===== 思路 =====
// [d6b3_] APPROACH -- experimental submission (purpose stated below)
// 【目的】判决律 565 的因果归属：#125002 与 #125003 的 **9.173861 ms** 板面差，
// 究竟住在【二进制内部布局】还是【功能（预取地址本身）】？
// 【本席的静态审计（先做，不动板面）】把两件用判题同款 g++-9.3 `-O2 -static
// -std=c++17 -frandom-seed=<fixed>` 编译后逐字节对比：`.text` 两点**同为
// 643 208 B**，objdump 反汇编**逐指令同址**，全二进制差异**只有 10 个 disp32 立即数
// 0x200 -> 0x600**（3 条源级 `prefetcht0` 被内联成 10 个机器实例）。⇒【布局】（指令
// 位置/边界/分支目标/DSB 落位）在两点间**逐位相同**，不可能解释 9.17 ms。
// 【判题机同二进制多臂判决（本席器械，`d6b3_inst`：单二进制 + 运行期选路）】把预取目标
// 地址做成**运行期寄存器值**（指令字节、指令地址、地址形成方式全部逐位相同，臂只是
// 一个数据值，成本对称是结构性的而非实测的）：
// n=2048 判题机实测（每臂最少 3 次读数，同进程交替，冷税 4 900 kt 已按位次扣除）
// F0(pks+0) 933 865 kt N512(pks-2048) 941 950 kt
// F512(pks+512) 945 673 kt F1536(pks+1536) 978 921 kt
// ⇒ Δ(F1536-F512) = **33 248 kt = 9.23 ms（墙钟）≈ 9.39 ms（板面 /3540）**
// = 板面两点的 9.173861 ms（差 2.4%）。★ 同二进制 ⇒ **【功能】判决成立**，
// 且律 565 的「自由通道反号」是**跨探针/跨件比较**的赝像：在同一进程内，自由
// 通道对 S_512/S_1536 的读数与板面**同号同量级**（见 dol §3）。
// 【本件是什么】本件 = 在役件逐字节副本 + 上述器械的**最优臂 F0**（预取目标 = 当前
// 迭代即将读取的同一行，即"距离 0"）硬编码：`prefetcht0 0(%[pks])` / `0(%[pky])` ×3
// （pks 侧 1 条、pky 侧 `.if sg==1`/`.elseif sg==-1` 各 1 条），位移常量为编译期常量、
// 由汇编器直接折进 disp 字段，指令数与在役件**逐条相同**（无额外 add、无额外寄存器）。
// 【为什么选 F0】本席曲线（n=1024 七臂、n=2048 七臂）显示该族**最便宜**的臂就是 F0：
// 该族只能"加流量"，任何真实 DRAM 目标都变慢（512→+3.34 ms、1024→+8.82、
// 1536→+12.73、2048→+7.86、4096→+1.57 ms，对 F0），最优臂 ≈ 中性。
// 【值中性】纯预取、无架构可见副作用、不改任何数据/地址/顺序；四档锚
// 7235d94f / f52f809d / 7e1f2b18 / 26d81789 与 C 全字节 FNV 逐位复现（判题机 + 本机）。
// 【发放件 = 所量件】本文件本地判题同款编译、跑四档闸门、objdump 逐条留证后再发。
// 【纪律】不设更严门槛；本件是**试验性提交**（目的：板面复核该族 + 同码锚量带）。
