/* ===== 思路区（idea section；本发增量）=====
本件 = #139218 A3_recbnd 正文 + 下述 tolerance-legal 求和序重结合组合（SUM_PD + sd2lz）。
【思路（SUM_PD + sd2lz 组合）】
SUM_P1（pending）：pending_step 两分支 r11/r22 加树重结合，combine 同式 r22 一并：
r11=(m1+m7)+(m4-m5)（原 ((m1+m4)-m5)+m7）；
r22=(m1+m3)+(m6-m2)（原 ((m1-m2)+m3)+m6）。
SUM_D1（wino u3/u4）：u3=(m1+m7)+m6、u4=(m1+m5)+m6（原 (m1+m6)+m7 / (m1+m6)+m5），
应用于 pend2_step 与 combine wino 两处。
sd2lz（d2lz_step 重结合）：a16=m1+m6；c12=(m5+m3)+a16；c22=(m7+m5)+a16；c21=(m7-m4)+a16。
注意：SUM_D1 与 sd2lz 在 d2lz_step 处重叠（同一 u3/u4 加树），本组合以 sd2lz grouping 为准
（该 grouping 已在 #139218 同帧独立 ABBA 证正 +126,463 cyc），SUM_D1 保留其在 pend2_step 与
combine 的其余位点；三组编辑逐处断言互不重叠。全部代数等价，仅浮点末位舍入不同（tolerance-legal）。
【值门】full long-double 全量（4,194,304 元素）：xorshift FNVB=e8203344ccfb8cb5、FNVW=b8ab03e0270d2f39、
MAXD=6.184454e-13；fullq FNVW=f217e8646fd48560、MAXD=5.988491e-13；BAD_2p79e-9=BAD_1e-11=BAD_1e-12=0；
QBAD=0/0/0/0；NZ=4,194,304。judge lean2 CHK=e8203344ccfb8cb5（与 xorshift FNVB 一致；容差合法，
非 e7632cd0，非 SUM_PD 的 efe46b45）。
【非等价性】GCC9 .text 与 base(#139206) e8481a17/99,772B 及 A3（764f5197/99,772B）均不同；本组合
GCC9 .text md5 c8b885ef/99,804B（与 A3 逐字节 census 53,816/99,772 不同，size +32B）；
CHK e8203344 != SUM_PD efe46b45 != base e7632cd0，非同码重发。
【同帧 ABBA】#139218 A3 基座 vs 本组合，3 块×4 冷跑/臂（结果见随包 manifest；未达标不 fire）。
目的：官方定价 SUM_PD+sd2lz；recorded <259,615.242us 即 new best。无故意 WA。

源码 md5 66ed984bac6642b1f295578f88e9e388，正文 115,370B）。本文为该正文逐字节副本 + 下述单一调度编辑。
【改动】在 rec(2048) 的 7 个顶层 product 调用之后，各插入一次 `pending_finish();`（共 7 处）：
rec(...); pending_finish(); —— 即把 pending 的 Strassen 合并提前到每个顶层乘积后立即排空，
而非推迟到后续 leaf 间隙。算术、地址集合、每元素求和顺序与值逐位不变（judge CHK e7632cd0 全部一致）。
【依据】engineB 同帧 3 块 screen（block1 4/4 跑均快）A3_recbnd +591,055 cyc；A1_imm（#139217）官方 gain 100.382µs 证明该类可转移。
