 `VirtualizedTree.vue` 基于 `@he-tree/vue` 的 `Draggable` 实现虚拟渲染和拖拽交互，只负责树 UI，
 不调用 API；不要替换为 Element Plus `el-tree-v2`。
+“全部”入口 ID 使用当前工作空间 ID；未传入 `v-model` 时，在实例创建时读取该 ID 作为默认选择。

 不要创建收集无关常量的通用文件，也不要为了统一导出而新增只做二次转发的 `index.ts`。
 常量名称使用能够表达所属领域和用途的全大写命名，使用方从具体文件直接导入。
 
+`folder.ts` 的 `FOLDER_ENTRY_ID.ALL` 与 `FOLDER_ENTRIES` 的全部入口 ID 在读取时取当前路由的工作空间 ID，
+不在模块初始化时缓存；无工作空间上下文时保留 `default`，共享入口固定为 `shared`。
+
 后端枚举与类型归属统一见 [API_README.md](../api/API_README.md#枚举与类型组织)。`constants` 只维护标签、颜色、选项等前端映射；映射的键应引用
 API 枚举值。例如角色类型和登录方式以 `src/api/enums` 为唯一数据源，`constants/auth.ts`
 只维护它们的展示文案。
