I/O 完善台账

本页由原 CSV 派生，不是新的状态权威、执行记录或软件资格。 原编号、顺序和全部原字段来自 原台账。 源文件：docs/design/platform-refinement-execution.csv；SHA-256：e4496e72ba53be176407804fffa805ef5b12f9da1e0949d2f3e8a20292d27e8b。

不同台账范围重叠，不相加数量或计算全项目完成率。实现状态与软件、 物理状态分别解释；development_passed 不表示当前文档 HEAD 已执行。 qualification_record_authority 要回到精确结果索引判断源码和范围。 绝对 /workspace、/dev/shm 定位保留原字节，仅说明原执行主机位置； 可取得归档及 member 定位见 软件证据入口。

原退出字段只有原 CSV 中实际存在的字段；任务、资格前提和合同链接 也按原文保留，不能据此补造某次执行。
