 - `generate-copy` 这条执行链现在会直接推荐回到“最近生成”结果区，而不是再打开旧文案表单；LAN smoke 也同步把 `track-account / import-video-link / import-text / generate-copy / create-assistant` 纳入 action-registry 护栏。
 - 全局 `AI 视频 / 实拍剪辑` 主按钮也已经切到 direct-execute，会直接承接最近可派生任务，不再优先打开旧表单。
 - 全局 `写复盘` 旧入口现在也会优先围绕最近已完成任务 direct-execute；只有当前项目还没有可承接任务时，才回退到手工复盘表单。
+- 全局 `生成文案` 旧入口也已经做成相同分流：优先围绕最近完成任务直接生成，只有没有可承接任务时才回退到旧文案表单。
