清库半删除等异常会留下 owner 已死但状态仍为 publishing 的 generation 标记, 后续读取直接抛 EnrichedGenerationUnavailableError, 步进优化连锁失败。 - 读取侧仅在「owner 是其他进程且该进程已死」时判孤儿并在独占锁内 自愈 (换新 uuid 重建 ready 标记); 同 pid 无活跃对象时保守不判, 避免暴露清库半删除的数据 (fail-closed) - 回测引擎改为 data_generation_await 轮询等待 (300s 上限), 遇短暂 publishing 自动重试而非直接失败; worker 错误文案同步为可重试提示
