+服务启动将遗留 `running` 请求标记为 `interrupted`，保留已落库的部分回答和用量，不自动重放请求。最近成功保存的上下文可直接用于下一次提问。任务主会话若没有主 Agent 快照，会在任务已有描述、Planner/Worker 结果或发现记录时使用只读任务级上下文；每次 GET/POST 都按当前任务材料和当前模型重新构建 `RunID=0, Version=0` 的合成快照。数据库中历史遗留的 `(0,0)` 行只用于旁路会话初始化，不作为最终上下文返回，也不会进入 `side.latest/seen`；后续真实检查点（`RunID>0`）始终优先。会话、Worker 和审批旁路仍要求各自的 Agent 快照或审批材料；确实没有可用材料时才提示对应的准备方式。
 
 清空操作递增清理版本并删除请求；条件更新阻止迟到的回调重新写回。物理父资源删除依靠外键级联，Worker 逻辑删除在同一事务中删除旁路数据，并拒绝后续迟到快照。任务归档先阻止新请求、等待主流程停止、取消并等待旁路落库；归档格式为 v3，同时兼容不含旁路表的 v1/v2。
