// [4] 本席（**s4az_**）在 [1] 之上新增两处改动：
// * S1 —— `mul<N>` 内第一对 combine 对调（先 `y=b22-b12` 再 `x=a11-a21`）。
// * C5 —— `native24_panels` 内环把 ymm13 这条 b 行改为内存操作数腾出该寄存器，
// 并把稳态每组改为「三条 madd 独立写 ymm13/ymm15/ymm14，再发三条 padd」
// （依赖距离 1 -> 3）。指令数不变：删 16 条 `vmovdqa`，64 条 madd 改内存操作数，重排 60 组。
// [5] 判据来源：本席装置 `work/s4az_mk.py`（全程序 rdtscp 探针，judge custom-test，零发数）
// 与 `work/s4az_ct.py`。判题机同批同码双锚位置伪影实测 0.03%。
// [6] 本席（**s4bb_**）在 [4] 之上新增两处改动（均**逐位等价**、判题机同批实测）：
// * FUSE —— 根端 `combine3_unpack` + `unpack_add` 合一为 `root_fuse`：一次读 p1..p7、写 C 四象限
// （p1 由二读变一读，省 8.39 MB 重读 + 一遍循环开销）。判题机实测 −1 470 438 拍。
// * CBORROW —— 借**调用方 `C`**（题面保证：非 const、4096 对齐、启动初值为 0）的前 3·RS 元素
// 作 a11/a12/a22 三个「纯输入」根槽（它们在根端融合写 C 之前已被 mul #5/#6/#7 消费完，
// 随后被根端输出覆写 ⇒ 无冲突、结果逐位不变）；`root_mem` 15 槽 → 12 槽。
// 判题机实测 −4 348 560 拍；`mem_kb` 同步下降 25 600 KB = 6 250 页（= 3 槽）。
// * 合计：1 982 481 706 → 1 976 658 708 拍 = **−5 822 998 拍（−0.29%）**，ck 逐位 9901480129097868163。
// （同批另测：把 root_mem/ws 的按需缺页移到 `__attribute__((constructor))` 的组合件在判题机
// 口径下**净负 +1.83 ms**（构造函数被计入、且孤立缺页价 884 拍/页 > 引擎内 583 拍/页）⇒ 判负，不入件。）

// ===== 思路 =====
// 【本件性质】真机器码候选 = [1] 对手 pdoom #117569 正文 + [4] 本队 S1/C5-real + [6] FUSE + [6] CBORROW。
// 【FUSE】根端两遍合一（`combine3_unpack` + `unpack_add` → `root_fuse`）：同一个 4096 元素块里
// 一次读 p1..p7、算 4 组 temp、写 4 象限，省一次 8.39 MB 的 p1 重读与一遍递归/循环开销。
// 【CBORROW】按需缺页税是本引擎的第二大成本项（(s4at_) 判题机实测 583 拍/页；root_mem 15 槽
// = 31 201 页）。借调用方 `C` 的前 3·RS 元素承载 a11/a12/a22 三个纯输入根槽：
// 这 3 槽在根端融合开始写 C 之前就已被消费（a22→mul#5、a11→mul#6、a12→mul#7），
// 其内存随后正是 C 的输出区 ⇒ 用它们不新增任何页（C 的页无论如何都要被输出写），
// 而 root_mem 直降 3 槽（25.6 MB）⇒ 判题机实测 −4 348 560 拍、mem_kb −25 600。

byte-shuffle truncation for the micro24 eight-column tail; memory masks;
compiler scheduling options, three-row scheduling in micro16, unroll-4 combine.
pdoom experiment: keep the leaf output in its native vector packing.
Keep both 24-column panels in one explicit asm loop.
Pair eight-column tails from adjacent rows into one full-width store;
only decode the final root output, in four-row L1 scratch blocks.
These extend our #112312 and retain its exact arithmetic and root dataflow.

mod-65536 Strassen-Winograd engine, recursive packing and AVX2 pair-dot kernel.
saffah_cc_v41_agg1 #112006, https://duck.ac/submission/112006 : baseline code,
peeled first k pair, cache offsets, and packing that eliminates output shuffles.
saffah_codex_6s_agg2 #110387, https://duck.ac/submission/110387 : fused root

saffah_cc_v41_260924 #96771, https://duck.ac/submission/96771 : cache phase idea.
pdoom changes in this version:
- Fuse the root's eight input transforms with 64x64 packing. Stream the six
retained raw quadrants and eight transformed quadrants to their packed slots.
- Reuse six retired root input-form slots for products: only 15 root slots.
- Write two adjacent 256-bit vectors per destination to complete each 64-byte line.
- Put 64 uint16_t padding elements after each 64x64 tile, and 32 elements
between root slots; all index arithmetic uses the padded recursive footprint.
- Traverse B packing by k-pair before column panel, reusing adjacent input lines.
Inherited improvements from our #112187, https://duck.ac/submission/112187:
- Vectorized A 4x8-dword transpose and 256-bit B interleave while packing.
- Eight k-pairs per loop body; first k-pair initializes the accumulators.
- 1024 uint16_t elements between workspace slots, separating cache phases.
- Omit the first loop-exit check: every supported leaf has n=64 and 32 k-pairs.
All products, sums and differences are exact modulo 65536. Specialized to n=4096.
