All supplied attribution and license notices are retained below; named public-source attribution follows those notices.
Idea: branch each live single-quadrant B panel into its two later consumers in one pass. From packed B22 form M7's B21+B22 and M3's B12-B22; from packed B11 form M1's B11+B22 and M4's B21-B11. Each pair shares the old panel read and undo-shuffle, cutting one complete source-quadrant read with unchanged exact64-bit adds/subtracts. Retain the second panel temporarily in unused existing B workspace, with64 elements of separation for native lookahead. Consume each pair consecutively and keep all seven products in their original distinct destinations before unchanged reconstruction. No extra global allocation or arithmetic kernel change.
Purpose: test a two-panel operand lifetime that reduces source traffic without retaining all seven panels. Validate complete scalar256 matrices for three strides and six shapes, then all4096 outputs and guards before official timing. */

* saffah_v41f1017_agg4 https://duck.ac/submission/137362: copied the complete public L4 engine, including its indexed fixed64 kernels, wider transform loops, product traversal, instruction schedule and all inherited source/license notices retained below. Its license notice identifies this as the author's public submission with named attribution; this header names the author and original URL and preserves the supplied notices. Historical diagnostic and scheduling statements below describe that source's history, not this experiment's procedure.
* saffah_codex_6a_agg3 https://duck.ac/submission/140831: copied the exact carry-preserving packed-B update helper and its two reuse sites. Its inherited concept credit is saffah_codex_6a_agg3 https://duck.ac/submission/139858, packed-B reuse in the double engine. No additional license was declared for those public submissions.
Idea: combine the faster published indexed arithmetic engine with our new positively measured packed-B reuse. M5's packed B22 becomes B21+B22 for M7, and M2's packed B11 becomes B11+B22 for M1. Undo the32-bit limb swap before each64-bit addition, then restore it to retain carries exactly. Preserve the adopted product order, remaining operands, reconstruction and native kernels. This combination has not previously been submitted.
Purpose: measure whether reduced source traffic also improves the published indexed kernel's different instruction and traversal schedule. Require complete modulo2^64 scalar reconstruction tests and full4096 output comparisons before the official submission; timing decisions use only Duck results. */

// 【依赖检查】写者实例级数据流模拟：每条读寄存器的写者实例与基座逐实例同、环尾寄存器状态同；不跨 `add $16,%[idx]`/`jne` 屏障（环内 idx 不变 ⇒ 全部访存地址逐字节同）；环内无存，载序不改变存储语义。
// 【机制】mikro_i rows=6 双 k 环占引擎 ~92%（在册隔离环 722.5 ≈ in-engine），环 41 fused uops/2k、端口 LP10；本项只改一条内存指令相对 FMA 端的发射相位（B 载/A 广播/预取），不改任何数据流。

// 【本发增量·布局位置】相对 #136815：把文件级布局垫移入 matrix_multiply 的永不执行冷路径（n<0 分支，NOP 剂量 23B），总 .text 长 123,443B（−6 vs #136815 的 123,449B）、机器码新、语义与数据地址不变；用于检验热函数绝对相位/DSB 集映射能否由垫位位置调控。原回补说明：
