// ⇒ 前瞻只在"带 = 整数条 cache line 且被前瞻全覆盖"时兑现。

// 【机理（判题机侧实测，本席第一手）】pass A = 219 ms 读 8.45 GB 逻辑字
// （3e5 query × 6 dim × 586.8 words × 8 B）= **38.6 GB/s ≈ 双通道 DDR4-2666 峰值** ⇒
// **DRAM 带宽墙**（池 28 MB ≫ L3；每条数组被 ~224 个查询读、复用距离 ~5.4 MB ⇒ 近乎零
// 缓存复用）。n13a_ 的"6 车道全指 164 KB 热缓冲"消融（219→75 ms）证明算力只需 75 ms，
// 其余 ~144 ms 全在等内存 —— 本条刀就是把这 144 ms 拿掉。
// 【做法】1) 组内查询按 R = s_gt[ds][i] 计数排序（R 升序）；2) 每 query 预计算
// [R, 6 个池字偏移, i] 写进 32 B 记录（1.4 MB/组，L2/L3 命中）；3) 外层按 band 扫、
// 内层沿 R 升序扫活跃查询（活跃集 = 排序后的后缀）：
// · 整带（R ≥ 512(bk+1)）：8 words × 6 dim 的 AND 树 + 半字节 LUT popcount；
// · 部分带（每 query 恰好一个）：用原 and_popcount_range 处理 [8bk, Wr) + rem 掩码。

// [2] duck.ac 用户 saffah_cc_v41_agg1（本账号），提交 #109583 <https://duck.ac/submission/109583>
// 用途：**本发唯一对照件**（= #109459 剥注释复刻 + `MF_QCOEF 32` + `s_bd` 行距 8；判题机
// **501.504070 ms** = 2D 网格 {31..36}×{7,8} 冠军格 = 本账号现役最佳）。
// 本发 = 该文件正文 **+ 唯一一处改动**（`pool_alloc` 加尺寸门控 `MADV_HUGEPAGE`，见思路）✓
// ======================
// ===== 思路 =====
// 【本发性质】**单变量**：相对 #109583（本账号现役最佳）只改 1 处 —— `pool_alloc()` 内给大块分配
// 加**尺寸门控**的 `madvise(MADV_HUGEPAGE)`（门控：申请 ≥16 MiB 才调用；纯分配提示，不碰任何值域）✓
// 【为什么（真官形状相位表定位）】`MF_Q` 未定义 ⇒ `solve_mf` 走自动 Q：
// `⌈√N⌉=548` ⇒ `q=(548·MF_QCOEF+99)/100=176` ⇒ `·kscale[3]=108/100` ⇒ **Q=191**，`B=⌈3e5/191⌉=1571 ≥ 400`
// ⇒ 粗网格过滤器**开**（旧本地 sim 用 harness 的 `n/250+1=1201` 是**错的形状**，结论已作废）。
// 相位表（本地 TSC 1.7957 GHz，`TIME≈975 ms`）：核 **80.5%** / 建台 **10.6%** / 池 **8.5%** / 预处理 0.85%；
// 消融定价（官形状 min-of-3，ms）：去 pass A −425、去 fringe −308、去池构建 −374（净，含带宽耦合）。
// `cat /sys/kernel/mm/transparent_hugepage/enabled` = `always [madvise] never` ⇒ 本机 THP **只**在显式
// `madvise` 时启用；而 `pool_alloc` 只 `malloc`+2 MiB 对齐、**从不** `madvise` ⇒ ~160 MiB 大块
// （sig 14.7 MB / fbm 61 MB / sdmp 67 MB / pool ~20 MB）全走 4 KiB 页：缺页 + TLB 双重代价 ✓
// 【改动】`if (bytes >= (16u<<20)) madvise(p, 向上取整 2 MiB, MADV_HUGEPAGE);`（对齐后指针，2 MiB 对齐）✓
// 【门控理由（全形状非负）】不门控版在 n=30000 形状 10 次交错 A/B **一致变慢**（min 28.40→30.00，
// med 29.25→30.95）⇒ 该形状 sig 块 14.7 MB < 16 MiB 被门控排除后，6 次交错 A/B = **平**
// （min 25.80→25.20，med 27.05→26.80）✓
// 【等价性证据（数值正控）】① 官形状 k=7 n=3e5 Q=191 checksum **704598241 与对照件逐位相同** ✓
// ② 暴力对拍 n=2000 mode 0..4：双方各 **0 失配** ✓ ③ n=30000/Q=60 与 n=100000/Q=401 checksum 逐位相同 ✓
// 【不执行对照臂】对照件 = `#109583` 原文件（无 `madvise`）；同机 `taskset -c 6 setarch -R` 交错跑 ✓
// 【定价（本地交错 A/B，min/med，ms）】官形状 8 次：对照 897.6/958.8 vs 本发 **875.5/912.3**
// ⇒ **−22.1 / −46.5 ms**（判题机换算 ≈ −11…−24 ms ≫ 判据 4.911434 ms）✓
// 【本发目的】红题、真更快 ⇒ **发件即定价**（严支判据 0.99·T+1µs = 496.592636 ms）✓
// 【口径】对照 mine = 501.504070（#109583）· T = 501.607713（#109459）⇒ 缺 4.911434 ms ✓
