+### 创作表单开始跟随来源任务动态刷新推荐值
+
+- `生成文案 / 创建 AI 视频 / 创建实拍剪辑 / 写复盘` 这四类创作表单，现在不只会在打开时算一次默认值；如果你在表单里切换来源任务，平台、标题、受众、画幅、时长、目标这些推荐值会继续跟着刷新。
+- 这套联动只会在字段还处于“自动推荐”状态时继续接管；一旦用户手动改过，就会尊重手改内容，不会再被来源任务覆盖。
+- `来源任务` 摘要区也会跟着联动更新，切换任务后第一眼就能看到当前承接的是哪条任务。
+- 为了支持这层联动，输入型表单里的 HTML 字段现在也带了稳定的 `data-action-field` 标记，后续继续做表单智能化和回归锁定会更稳。
