+## 真机回修（2026-11-14 晚）
+
+1. **未命名保存后文件树不刷新**：saveTab 只在新建/新建文件夹流程里刷
+   树，保存落点变化（未命名首次保存、另存为）时没刷。已补：writeTextFile
+   成功且路径变化时 setTreeRefresh +1。
+2. **侧栏拖拽显示禁止符号、drop 不触发**：实现本身（HTML5 DnD）在
+   DOM 层测试是通过的，真机失效的根因是 Tauri 窗口默认开启
+   `dragDropEnabled` 原生拖放拦截——它会吞掉 WebView 内的 HTML5 拖拽
+   事件（本应用没有任何功能在用原生拖放事件）。主窗口配置
+   （tauri.conf.json）与运行时新窗口（WebviewWindow 参数）均已设
+   `dragDropEnabled: false`。附带好处：编辑器内 ProseMirror 的文本拖放
+   同样被拦截所禁，一并恢复。若真机仍不行，下一步改指针式拖拽
+   （pointer events 自绘），不再依赖 HTML5 DnD。
