admin 18f59599e7 Fix #31/#32: 切B类GM每字节恰一次=V_in(去K切分整段上取) / ASW场景升级(单侧全驻留+对侧滑窗->S_B, S_C最小替换2D分组+窗口L2计账) / 06文档§3+Step5与docs/05同步 
#31 IterBatch/MergeBatch: K切分各(batch,K段)互不重叠+驻留侧每batch一次+末段按实际剩余
    -> GM读取量=V_in(与L2容量无关), GM数据时延=V_in/W_GM; n_K仅决定DMA命令数(T_cmd)
    b64_m16_n256_k512 形态c: GM 25.07MB->17.83MB=V_in; 回归: 形态c/d非整除+L1绑定三类断言
#32 ASW: (1)S_B扩展单侧全驻留+对侧滑窗(a_b/b_b+2*对侧单块<=L2) -> GM=V_in, 6个场景C行回落S_B;
    (2)S_C在整L2容量约束下搜索最小GM=ceil(n_cnt/n_grp)a_b+ceil(m_cnt/m_grp)b_b(取代L2/2对半预算),
    并计组内窗口L2流量((n_cnt-ceil)a_b+(m_cnt-ceil)b_b), 与S_B'驻留命中走L2'口径一致;
    b8_m131072_n8192_k8192 GM倍率4.76x->3.88x(物理下界~3.9x, 双侧均超L2)
    大方形K行(如b128_m8192_n8192_k7168)由MMAD 253ms->MTE2(L2口)295ms: 共享块重复读1.38TB
    经L2读口5.2TB/s, 如实计账(原C窗口流量零计低估)
- docs/06 §3与Step5重写为S_A/S_B/S_C+两段链口径(旧r_in单段/除B/对半预算口径废弃)
- docs/05 R5/R6/§3.1/§4.1/§4.3/§5与docs/01、02(01_MergeBatch/02_IterBatch GM口径附注)同步
- tests 54/54; 压力seed7/6000+seed2024/4000: 0违规/0占位/0NaN/0GM<V_in; examples重生成0diff
