// [B] 新增:A/B 两侧各 5 个和式融合为单次四象限遍历 + NT 流存储;组合缓冲零新增页
//     (A→MMS[0,1,4,5,6],B→MMS[2,3] 与 C 前 12MB;j 号组合在乘积 j 结束覆写前消费)。
//     判题机体验 1215.60M→1204.40M 拍(−0.92%);n=4096 seed=12345 FNV 逐位相同。
// ================
// [C] 二次下沉(本发):把同一 A 侧 5 和式融合下沉到 submm_s2 层(2048→1024):该层 7 个乘积原本
//   各做一次 blk 双源拷贝(A 侧共读 ~12MB/次);现改为先一次四象限遍历写 5 个 tiled 组合
//   (NT 流写;槽位 S2M[0,1,4,5,6],生命周期同根级:组合 j 在乘积 j 结束覆写前消费),
//   sum 类乘积把组合缓冲既作 Ap 又作 Cp 直传 submm_s4(免 S3A 拷贝);B 侧与纯块 case2/3 不变。
//   判题机体验 1193.8→1189.7M 拍(−0.34%);n=4096 seed=12345 FNV 逐位相同。
// [D] 2026-10-23 agg4 lane mmmc4k:完整 A 侧删除。根 build_combsA5 物化删除;5 个 sum 乘积的
//   s2 组合直接读原始根象限构建;case2/3 所需 Ap 顶左/底右 tiled 象限由同一遍构建写入输出槽
//   S2M[2]/S2M[3](就地消费后覆写),sum 的 A 侧 blk 拷贝删除。A 侧账 127MB→101MB(−6R−20W)。
//   FNV n=4096 = 2e9a2fdaf0565988(两遍逐位同 adopt_139830)。
// [E] 2026-10-23 agg4 lane mmmc4k follow-up:B 侧秩删除。七个 B case 操作数秩 4;
//   基 B0,B2,B3,B4,B1=B0-B4,B5=B0+B2,B6=B0+B3。基仍由 blk 写 S3A/S3B;
//   三个派生 case 删除 blk 拷贝,在 s4 的 B-pack 读取处双源求和(无新静态页)。
//   纯块 A 象限并入 build_combsA5t 输出,pure A blk 删除。FNV 2e9a2fdaf0565988。

* saffah_codex_6a_agg3 https://duck.ac/submission/128086: accepted independent-pitch immutable root quadrant views at size8192, transferred here to the 2048 child driver.
* Idea: Pass the root's four plain 2048 input quadrants as immutable strided views instead of copying them to SA/SB. Give submm_s2 independent source pitches for its first materialization; all deeper products remain contiguous. This removes four complete 4-MiB copy passes without aliasing output or changing any byte arithmetic.
* Purpose: Reduce root memory traffic while retaining the current leaf, correction tables and signed packers.

* Idea: The production recursion uses 256-square leaves. Express the second packed A row with its fixed 512-byte displacement from the first row, deleting a live address register and its setup/update. In the 4096 engine, also address the second output/parity rows by their fixed 256/32-byte displacements. Arithmetic, pack representation and traversal stay unchanged.
* Purpose: Measure reduced address work for the problem's fixed-size production path; verify the complete official-size matrix over all signed-byte edge patterns.

* These public submissions state no separate license; inherited notices are retained.
* Idea: Combine a sixteen-KiB mixed-width correction slab with the initialized 256 leaf. Two fixed-width builder loops remove group-width branches, preserve register-only Gray generation, and index the unpadded 64-row B masks directly. Pair queries on two independent chains per row.
* Purpose: Reduce table construction and cache occupation relative to the accepted uniform partition while preserving every modulo-256 product; only official judging determines speed.

byte matrix engine and full original citation/license chain below.
Idea: The production engine always calls the forward microkernel on 256-square
leaves. Remove its unreachable eight-element remainder and empty-loop guards.
Initialize the eight accumulators directly with the first byte-pair product,
then enter the existing unrolled ring at its second pair; later rings retain
exactly the original order. This removes eight zeroes and eight adds per
microcall without duplicating the full loop. Purpose: reduce real leaf work
and hot code size while preserving all mod-256 products and parity correction.
