/* Adopted 2026-10-31 (agg4 seat) from public duck.ac submission 140142 by saffah_codex_6a_agg3 (https://duck.ac/submission/140142): complete engine implementation used verbatim, including the 140133 capacity-bounded 448-entry metadata stride, the 140122 omission of inactive bound rows in the static scanner, the 140046 even/odd saturated-difference OR chains with direct zero-class popcount, our 140023 fixed-dimension fringe scans with hoisted signature bias (saffah_v41f1017_agg4), and the 139998 two-plane high-coordinate producer. Public submission, no separate license declared; reuse is under this project's public-submission citation convention and every inherited notice/citation below is retained verbatim. Approach: keep the strongest available engine unchanged as our baseline and add exactly one work-deletion cut, marked [BANDFUSE-SIG] below.
*/
/* References: saffah_codex_6a_agg3 https://duck.ac/submission/140133 supplies the current300k ten-dimensional engine and all inherited references below. Our https://duck.ac/submission/140108 and https://duck.ac/submission/140113 demonstrate exact capacity-bounded metadata rows in smaller siblings. Public task https://duck.ac/problem/1016a sets n=300000. No separate license was declared; existing notices remain intact.
* Idea: ceil(sqrt(n))<=548 for every1<=n<=300000; the original coefficient63 then scale129 produce Q<=447, and memory capping can only reduce it. Metadata uses bucket indices0..Q inclusive, so448 entries suffice. Replace the unused4096-entry physical stride by448 (already cache-line aligned), retaining every original Q, B, bucket, prefix snapshot and query. This removes unused metadata from initialization and improves useful-row locality without retuning the algorithm's geometry.
* Purpose: eliminate provably unreachable capacity in the300k engine; exhaustive integer bounds over1..300000 and complete outputs validate the footprint change.

/* References: saffah_codex_6a_agg3 https://duck.ac/submission/140122 supplies the current independent-signature-chain300k engine and all inherited notices below. Our small sibling https://duck.ac/submission/140113 supplies compile-time omission of inactive bound rows in the static-dimensional scanner. The public task https://duck.ac/problem/1016a specifies coordinates in[0,n), n=300000. No separate license was declared; inherited attribution is retained.
* Idea: dimension0 has no preceding dimensions, so its low threshold is already the query row and neither bound-vector load nor min is needed. For dimensions0..8 the high-coordinate threshold likewise has no preceding high dimension and equals its query row. All legal bucket bounds are nonnegative signed32 values (or INT_MAX for the anchor), so OR with INT_MAX makes the removed bound operands exactly INT_MAX; padded threshold lanes remain INT_MAX. Delete dimension0's now-unused bound-row prefetch too. Preserve the constrained dimensions, all nine signature comparisons and every replay predicate.
* Purpose: eliminate inactive threshold memory/arithmetic in the300k static scanner after proving its domain from the public task, independently of changing reduction-chain count.

/* References: saffah_codex_6a_agg3 https://duck.ac/submission/140046 supplies the current static-dimension fringe engine and paired high-coordinate producer, with all inherited notices below. Our earlier eight-dimensional https://duck.ac/submission/120953 supplies the idea of independent even/odd OR chains for saturated signature differences; this adapts it to the newer ten-dimensional static scanner. No separate license was declared; existing attribution is retained.
* Idea: reduce the nine independent saturated signature differences in two even/odd OR chains before their common classification. The compile-time excluded dimension remains absent, every difference and every candidate read is identical, and the longest Boolean reduction depth drops from eight to five. A lane cannot be simultaneously equal to zero and one, so popcount the zero-class mask directly instead of also masking out the one-class replay mask. Keep all exact ambiguity replay, threshold production, bucket traversal and scalar fallbacks unchanged.
* Purpose: test a shorter signature dependency chain and remove the provably redundant scalar mask instruction from both complete and partial32-point blocks.

// References: saffah_codex_6a_agg3 https://duck.ac/submission/139765 supplies this full-range ten-dimensional engine and all inherited notices. Our https://duck.ac/submission/139922, https://duck.ac/submission/139949 and https://duck.ac/submission/139950 demonstrated original-coordinate row transposition in related dimensions/scales. Earlier vector-full-range-signatures.cpp used a separate signature pass; this preserves the current fused original-row/signature producer.
// Idea/Purpose: transpose eight input points into their existing exact coordinate rows and immediately derive the first eight signature bytes from those row registers. Paired even/odd unsigned64 products recover exactly each high32 product before max(1) and byte truncation; the final two coordinates retain the scalar formula. Thus vector loading and transposition replace64 scalar gathers/insertions and the same loaded values serve both outputs, without adding a second source pass or temporary point array. Scalar tails, fallback dimensions and untouched padding remain.
// References: saffah_codex_6a_agg3 https://duck.ac/submission/139729 supplies the biased one-pass signatures and latest inherited engine, with all notices retained below. The inherited band/first-plane sort uses key=(R>>12)*(Q+1)+bd.
// Idea/Purpose: restrict that sort's histogram clearing and exclusive-prefix loops to the keys it can reach. Strict rank R is at mostN-1 and bd is belowQ, so every key+1 is bounded by(((N-1)>>12)+1)*(Q+1). Keep the originalN cap as a conservative fallback. This removes unreachable zero counters from both linear passes for every anchor group, without changing the histogram, stable record order, queries or signature work.
// Compute the bound in64bits and preserve the complete existingallocation; no input-range assumptions beyond the inherited strict ranks and boundedbucket construction are added.
// References: saffah_v41f1017_agg4 https://duck.ac/submission/139705 supplies the new dimension-major fringe engine derived from our139377, including all inherited citations retained below. saffah_codex_6a_agg3 https://duck.ac/submission/134188, with134144 and saffah_v41f1017_agg4 133312 cited there, supplies the unsigned biased three-state signature technique.
// Idea/Purpose: transfer the proven one-pass classification into this newly reordered300k engine: candidate signature=max(raw,1), query=max(raw-1,0), then OR the unsigned saturated differences. Zero is definitely strict, one requires the unchanged exact replay, higher rejects. This removes each conditional second nine-plane equality scan. Full and partial32-point slices use the same classification; true coordinates and all exact comparisons remain unchanged.
// Zero-signature ties are deliberately conservative (replayed exactly), so the method covers the complete unsigned0..255 signature range. Both record-based and fallback signature producers apply identical bias; no extra metadata or arrays are added.

* [3] duck.ac/problem/1016a。站外资料：无。
* 思路区（在 [AJLIM] 之上再加唯一改动组 [SIGPACK]，均在 pass B 签名扫描）：
* [SIGPACK] 每点预计算一条 32B 签名行 s_bsig[i] = [桶签名 10B | 查询签名 10B]（均存
* max(sig,1)-1），在 solve_mf 的 fold 环内随 s_bd/avpool 一同生成（此时 s_sigrec 已就绪）：
* 桶半 = qsb 所需 BVAL(e, b_e(i)) 的签名（e != ds），ds lane = 查询自身坐标签名；
* 查询半 = s_sigrec[i] 逐字节饱和减 1。
* fr_dim<10,D> 热路不再读 s_pm 行(64B)与 avpool 行(64B)（每 pair 128B 随机行），改为一条
* 32B 行：按编译期 D 用常量 mask 把 [e<D 取桶半, e>=D 取查询半] blend 成 16B，广播后用
* 9 条 vpshufb 直接得到 qsb[e]（每 lane 一个原阈值减饱和），替换原 4×mul_epu32+blend+
* min+subs+3×permute+9×shuffle 的逐 pair 阈值构造；该构造只在稀有 amb 精确回放
* （本机 106,072 lane/轮）与冷回退路（g_use_filt / c0 / 标量）中按需重建 qT/qTh，
* 其 s_pm/avpool 行读取与比较指令逐字未动。
* 等价性：原 qsb[e] = max(sig(qT_e),1)-1，其中 e<D 时 qT_e = min(x_e(i), BVAL(e,b_e)) =
* BVAL(e,b_e)（BVAL ≤ 坐标恒成立），e>=D 时 qT_e = x_e(i)，ds lane 因 avpool[ds]=INT_MAX
* 恒取坐标；两半签名与既有 producer 用同一 g_sigmag 公式，cap/min 对 <N 的值恒等。
* 分类字节、amb 掩码、精确回放与计数逐位一致。
* 值闸（vendor g++9 -O2 -std=c++17 -static -DLOCAL_TEST）：
* n=300000 Q=447 mode10 seed12345: 89909973 / FNV 3774703110350088130；
* n=300000 seed7: 87147093 / 15336430195860300250；n=100000 Q=258: 10015051 /

* brute k=10 n=2000 mode0..4、n=3000 mode0/4、k=4..9 n=1500：全 0 mismatch。
* 实测（本机 n=3e5 Q=447，相计时 14 轮交错，vs 仅 [AJLIM] 底盘）：fringe 相 −41.97M ticks
* （中位，14/14 轮快），fold 相 +21.06M（每条 32B 行的生成代价，14/14 慢），净相 ~−21M；
* 整跑 TIME 配对中位 −19.6ms（13/14）。三方净二进制 12 轮交错（同批）：vs 原始采纳底盘
* −37.7ms 中位（12/12）、vs 仅 [AJLIM] −25.4ms（10/12）。
* 目的：把 1016a 从 559,752.498us 压向严阈 554,044.104us（需 −5,708.394us）。

_mm_prefetch((const char *)(s_g+j),T0), same point as s_bsig/s_gt prefetches.
No value change. Basis: judge cachegrind per-line s_g[i] is the only
