mem_map_retain 原生盒边持有：Map 持 20000 组字符串键 + 对象值
mem_set_retain 原生盒边持有：Set 持 20000 个对象（各带 payload 字符串）
mem_string_rope 拼接 rope 链留存：重复二元拼接形成深 Cons 链（账目按逻辑长度计，数值高于实际足迹）
口径：Peak B/Ret B 为 session 堆账目（对象头 + 堆数据 + 存活串/BigInt）；JSON 的
`epoch_objects`/`epoch_bytes` 为恒零锚字段（epoch 分配器退役后保留 schema 兼容），
不计入字节账目。Peak B 为顶层指令边界采样的 session arena 高水位；单指令内瞬态
不计。Ret B 为 workload 后强制完整 GC 的真存活集。
口径：Peak B/Ret B 为 session 堆账目（对象头 + 堆数据 + 存活串）；BigInt 不入
该账目，由单 run 分配公式按表长单列。epoch arena 的临时驻留不计入字节账目
（数量列恒零）。Peak B 为顶层指令边界采样的 session 堆账目高水位；单指令内瞬态
与 epoch 高水位不计。Ret B 为 workload 后晋升 + 完整 GC 的真存活集，至多含一份
引擎内部副本：逃逸屏障留 epoch 原件且顶层寄存器根不回写时，测量时晋升会把原件
再克隆一份（object_graph 见留存锚测试）。
A/B 判据口径：
主判（回归门）：确定性列——指令数、内存账目（session/peak/retained）、
垃圾回收计数、内联缓存计数——跨运行逐字节一致，零容差，双向任何变化即信号；
基线对比的退出码 1 只认这些列。
次判（墙时间）：wall/exec/compile/gc_collection 列在 ±5% 带内（固定核、
warmup 2、三轮中位）；基线对比容差 0.50，信息性，不影响退出码。
基线文件是陈旧锚（安静树单次快照），不是 A/B 仪器；A/B 是同机同宿主
严格交错对比。
