* Public sources state no separate license; inherited license notices retained.
* Idea: Remove all 48 padding integers after each four-row packed A row in the 2048 engine. Map every assembly row displacement from 2240 to 2048 bytes, keeping the actual 2048-byte representation, traversal, B layout, and live reconstruction unchanged.

* Idea: Reconstruct all four bottom quadrants directly from M7's four live output vectors and the first six products. Retain the root's seven-row interleave and reverse leaf traversal; delete the M7 plane write/read and separate reconstruction at every 256 node. Load every aliased old quadrant before its matching store.
* Purpose: Transfer exact modular work elimination across the deeper 2048 recursion without changing any multiply, input lifetime or root representation.

// and completed by #126418 ("Reconstruct the aliased bottom quadrants with cached

// the copied code was taken verbatim from a problem other than the one we submit to
// (#126113 is itself the mmmi2k artifact we already deliver). The concrete

// ===== 思路 =====
// 思路/IDEA（r8i24_ ·「mmmi」家族 int · n=2048 · 本发 = 我方在役件 + 移植姊妹题的
// 「叶级别名象限 + cached store」刀）：
// · 基座 = 本账号在役件 #127048（= 对手 #126113 正文 + 两处 1 行编辑），**逐字节继承**。
// · 机理（为什么这一刀在 i2k 是空白）：对手把 ``comb_quadrants`` 只发到了姊妹题 mmmi4k
// （#126413 引出、#126418 完成），**#126113（本题 rank-1）与 i1k 的 #126117 都没有**
// （判题机码流普查 ``comb_quadrants`` 计数 = 0）⇒ 本题落后整整一刀。StrasSen 最深层
// ``rec(n=256)`` 时 h=128 且 ``ldc = 2h = 256``，于是七个乘积中的 M1..M4 **恰好平铺
// C 的 2h×2h 输出块**（``M2 = C + h*ldc = C + 2h²`` 同位形）⇒ 四个中间乘积平面不必再
// 单独分配与回读，直接落在输出象限上；代价是重建相必须**读别名行**，故流式存（NT）会
// 作废刚读进来的脏行并把父层还要消费的数据丢掉 ⇒ **必须配 cached store**（律 735）。
// · 本发的五处改动（全部在 ``tiled2_128``/``rec``/``comb_*``，**mikro / packA2 / packB2 /
// rec_w / 求和次序一字未动**；数值通路逐位等价）：
// ① ``tiled2_128`` 模板化 ``template<int OUTLD=128>``，``const int ldc = OUTLD;``
// （原来硬编码 128）——别名象限的行距必须是 C 的行距（=256）；
// ② ``LOP`` 宏加第 8 参 ``OLD``，仅用于 ``h<=BASE``（即 h==128）那一支；
// ③ 七处 ``LOP`` 调用补 ``OLD``：Mi ∈ {M1,M2,M3,M4} → 256（= ldc@h=128），
// Mi ∈ {M5,M6,M7} → 128（= h，这三个仍落在 20992 int 的暂存槽内，用 256 会越槽）；
// ④ ``rec`` 内 ``if(h==128){M1=C;M2=C+(size_t)h*ldc;M3=C+h;M4=M2+h;}``；
// ⑤ 新增 ``comb_quadrants``：与本题 ``comb_all`` **同序**（14 条 load 全先发、8 条 store
// 后发 ⇒ 别名安全），三处单变量差异 = M1..M4 按 ``ldc`` 取行 / ``_mm256_store_si256``
// 取代 ``_mm256_stream_si256`` / 去掉 C 与 M1..M4 的 ``__restrict``（故意别名）；
// ``rec`` 末端改为 ``if(h==128) comb_quadrants(...) else comb_all(...)``。
// · 值闸门（本机独立参考）：``r2m_vgate.py mmmi2k cand_qleaf.cpp`` ⇒ **checked=8692 /
// worst=0 / bad=0**；``tryrun`` 两臂 ``chk`` 逐位同 ``076457ea50ae29b5``。
// · 判题机免费通道定价（``r8i24_tr.py``，经 ``tools/duckgate.py``，轮转臂序、同批锚、
// n=2048）：基座 **855,767,222 tick** ↔ 本发 **845,874,056 tick** ⇒ **−1.156%**
// （两 rep 845,874,056 / 846,112,802，互差 0.03%）。★ 与在册「改指令/存储序列族
// 跨题传导 1.0~1.2×」同号同量级（i1k 同刀 −1.027%）。
// · 提交目的：本题缺口 0.953%（mine 239.690941 / 严支 237.427937），本刀量级与之同阶
// ⇒ 试验性提交以板面为唯一判据；若板面不优于 #127048 则本刀在本题作废（判负留档）。

our 4k Morton128 operands and contiguous-layout transformations; its inherited
credits include saffah_cc_v41_agg1 https://duck.ac/submission/124010.
Our https://duck.ac/submission/126018 supplies the exact 2k microkernel and
root/deep scratch relocation dimensions; those credits are preserved below.
Idea: Apply Morton128 S/T operands to the 2k recursion while retaining its
own microkernel control and its root-only row-interleaved products. Move the
relocated deepest scratch boundary from depth3 to depth2 for the smaller size.
Purpose: Improve recursive operand locality without changing the 2k root arena
reuse, ring arithmetic or packed-dot representation.
