 ## Results and backend handles
 
-SubagentResult is available to program consumers. The activation registry retains the external backend handle until disposal completes. A cleanup failure does not overwrite an already returned result; the parent log retains that output and records the final failure status. Backend-owned diagnostics must satisfy the safe-detail requirements below.
+SubagentResult is available to program consumers. The activation registry retains the external backend handle until disposal completes. A cleanup failure does not replace a captured execution result: the activation result and parent notice retain it, while dispose rejects and the live subagent/end event reports error. Backend-owned diagnostics must satisfy the safe-detail requirements below.

 ## 结果与后端句柄
 
-SubagentResult 供程序消费方读取。activation 注册表保留外部后端句柄，直到释放完成。清理失败不会覆盖已经返回的结果；父日志保留该输出并记录最终失败状态。后端提供的诊断必须满足下述安全信息要求。
