// ======================
// ===== 思路 =====
// 【本发唯一变量 = `micro24` 的两处 **B 预取距离**（入口 2304 B / 环首 2688 B）；其余一切逐字节同现役件】
// 装置事实（判题同款编译 + `objdump -d` 逐地址 diff，`work/s1zh_tmp/`，本席实读、非引用）：
// * 全引擎**只有 `micro24` 有预取**（剥皮块 1 条 + 环首每迭代 1 条）；`micro16`/`micro8` **各 0 条**。
// * 指令文本 = `prefetchnta 0x800(%rdi)`（**disp32**）⇒ 只改立即数 ⇒ **编码长度不变** ⇒
// `.text` 尺寸 20059 B 不变、**每一条指令的地址逐字不变**（逐字节 diff 只差这 2 个 dword）⇒
// **零落址、零条数、零语义** ⇒ 读数不可能被律 S1（"环外/条数改动收费"）或布局税污染。
// ★ 本席的几何事实（读 `base()` 的调用形态得出，不是假设）：`base()` 以 n = BASE = 64、U = uint16
// 调 `micro24(a+i*n, b+j*n, ..., n)` ⇒ **j 步进 = 24 × 64 × 2 = 3072 B = 一次 micro24 调用走完的
// 8 chunk × 384 B 窗口**。于是：环首预取在第 j 次迭代（j=1..7）打的是 `b0 + 384j + D`，
// 即 d = D/384 时覆盖 **chunk j+d**；`j+d ≤ 7` 时它在**本 panel 内**，`j+d ≥ 8` 时它越过窗口、
// 落在**下一个 j-block 的 panel 首部**。⇒ d≥8 不是"无效档"，而是把两个站点**变成前向预取器**
// （为下一次调用序列里那些 cold chunk 提前搬运）—— 这正是本席要测的**模式切换**。
// 覆盖公式（本席用）：in-panel 覆盖 = {6} ∪ ([1+7, 7+7] ∩ [0,7])，被覆盖的 chunk
// 一律拿到 **259 拍**（= d 个迭代 × ~37 拍）的提前量；d 越大覆盖越少、提前量越大。
// ★ 站点解耦（派单第 3 项）：**入口保留 d=6**（在档唯一被证明有效的入口档），环首推到 d=7 ⇒ 本 panel 只保 chunk 6，同时把环首那条**切换成前向预取器**（打下一个 j-block 的 chunk 0..6）。
// 读数口径：同批 ≥3 把**同码锚**（正文 = 现役件逐字节、只改一个常量拼写 ⇒ `.text` md5 与在册
// `mine` #117301 的证书**逐字节相同**）标定窗口；每把臂都与它的**同批锚**比，并与**锚时间序列内插
// 残差**双口径判读（(1218)：`mine` 在带下沿，真臂须先跨过 `mine` 才谈刷新）。
// ⚠ 诚实记录：d=5/6 两把在档臂同号但**未过 2× 带**；本席的臂同样按此纪律判读，不够格就写不够格。
// 闸门：判题同款 `ref/gcc9/g9.sh -O2 -std=c++17 -U_FORTIFY_SOURCE` rc=0；`.text` 20059 B；
// 与现役件逐字节 diff = **恰好 2 个 dword（两个 disp32）+ 0 其它差异**；ck 五点（n=64/128/256/512/1024）
// 与现役件**逐字同**；未动热环体/尾段/寄存器分配/clobber/约束；TMPDIR 题内（`work/s1zh_tmp`）、零 /tmp。
// ★ 预取不改变任何可见状态 ⇒ 语义无改动。
