// * 判题机 custom-test 冷/暖分离（work/s4bq_gen.py 的 base[-rep3] 臂，rdtsc 插桩两个 pack_root 调用）：
// 冷 28.66/29.34 M 拍 ⟷ 暖 18.78/19.28 M 拍 ⇒ 冷溢价 19.94 M 拍 = 29 120 页 × **685 拍/页**；
// 预触页臂（37 441 页 = 33.10 M 拍 = 884 拍/页）后**全部** pack 调用落到暖水位
// ⇒ 冷溢价 100% 是缺页，且预触页（884）比引擎内（685）贵 ⇒ 「预落页」结构性净负（与 (1368) 独立互证）。
// * 双热消融（读/写各换到热缓冲）：暖 A 18.78 = 读 10.33 + 写 3.36 + 核 6.64 M；暖 B 19.25 = 读 9.03 + 写 3.91 + 核 7.50 M。
// * 合成上限（判题机）：顺序读 26 GB/s · 本件读序 13.9 GB/s · 行组扫描序 24 GB/s（1.9x）· 融合 4 相邻叶 22 GB/s；
// 7 流 NT 写 32 GB/s；**同字节理想混合 = 12.6~15.0 M 拍** ⟷ 真 pack 18.8~19.2 M ⇒ 本件坐在混合带宽墙上。
// * 软件预取（A 侧 PD=4/8/16、B 侧 8，逐位等价）：判题机 **0~+1.7 M（负）**。
// * 「n=128 融合叶对」（相邻两叶按行组交错读，合成里读序改善 1.6x）：判题机 **+0.55 M(A) / +1.74 M(B)**；
// 原序对照 refactor-only **+0.60 / +0.88 M** ⇒ 读序本身在位内为负。
// * 槽步长相位扫描（ROOT_PAD 32/48/64/96/128/160/256/1024/2048/4128）：除 +96 B 相位（行重叠，+2.5 M）外全在 ±0.15 M ⇒ 现役即最优。
// [3] 本件用途：**仪器校验件（不是改进件）** —— 把 [2] 里「pack 相位 +Δ 拍」的预测送到**板面**，
// 回答全队悬案：探针通道的 **pack 相位**读数能否预测板面（(1349) 只说整程序口径对载入/存储类不可信）。
// 预测：本件板面应比同批锚慢 **+0.42 ms**（pack 相位 +1.48 M 拍 / 3.556 GHz）；若板面实测落在 0±0.15 ms
// ⇒ 该通道对 pack 亦不可信（新仪器律）；若落在 +0.3~+0.6 ms ⇒ 通道可用，后续席位可用探针廉价定价 pack 改动。
// ======================
// ===== 思路 =====
// 逐位等价重构（ck = 9901480129097868163，本机 + 判题机双侧一致）：
// 把 `pack_root` 的 n=64 基例拆成三个可复用函数
// （pk_rows_l/pk_rows_r = 一个行组/一对行；leaf_emit = 4-tile scratch 落 7 路流），
// 并在 n==128 处分派到 `pack_leaf2`（一次处理 n=128 节点的 4 个叶）。
// **本件保持原叶序**（每个叶的 4 个 tile 依次跑完，A 叶跑完再跑 B 叶），
// 仅改代码组织与 scratch 尺寸（root_tile 4*4096 → 32768 元素）⇒ 输出逐位不变。
// 用途：作为「融合叶对」的**同码对照**，供板面把「重排读序」与「重构/代码尺寸」两个因素分开。

scheduling, fused four-quadrant root output, borrowing C for root raw inputs,
and shift/blend truncation with deferred inverse word permutation.
Oded Schwartz and Noa Vaknin, Pebbling Game and Alternative Basis for High
Performance Matrix Multiplication, SIAM J. Sci. Comput. (2023), (3.1): the
exact seven-product, twelve-add alternative-basis decomposition over a ring.
https://epubs.siam.org/doi/10.1137/22M1502719
Retained lineage:
pdoom #86352, https://duck.ac/submission/86352 : exact mod-65536 engine,
recursive packing and AVX2 pair-dot products; #112312 : fused root packing,
retired input slot reuse, complete cache-line streams and padded leaf offsets;
#117569 : SIMD-native leaf output, delayed root decode and one panel asm body.
saffah_cc_v41_agg1 #112006/#117247 : peeled first pair, operand/output packing,
cache offsets, three-row tail scheduling and compiler scheduling options.
saffah_codex_6s_agg2 #110387/#102935 : fused root reconstruction, constant
recursion and instruction order. saffah_cc_v41_260924 #96771 : cache phases.
New pdoom changes in this version:
- At N=128 use the ring-valid twelve-add bilinear graph in alternative bases.
A fixed basis commutes with every upper-level linear combination. Apply
the input maps in the first raw loads and the inverse output map in the
final root reconstruction; no whole packed-matrix transform scans.
- Keep 64x64 leaves. The 24-column panel kernel peels two k-pairs and loops
six pairs. The tail peels eight pairs and loops four, holding all four
rows' products before adding;
the cached B register becomes the last row's product after its last use.
- Use C's dead tail for the recursive work area, before final C writeback.
- Preserve padding/cache phases, but never add or load/store padding values.
Every input and output is exact in Z/(2^16); no distribution assumption.
Specialized to the stated n=4096, separately allocated aligned matrices.
