 各入口复用自己的 Pinia：Admin 使用 `@/stores/admin`，Chat 使用 `@/stores/chat` 的 `useStore()`；
 Store 内部协调状态时可直接引用同入口的具体 Store，避免聚合入口循环依赖。
 `src/stores/index.ts` 当前是 Admin 兼容入口，不能用它获取 Chat Store。

+# 国际化规则
+
+`src/locales` 负责界面语言、语言包和入口初始化。当前支持 `zh-CN`、`en-US` 与 `zh-Hant`，
+默认及缺失文案回退为简体中文。语言包暂随入口加载，新增语言时再评估按需加载。
+
+## 分类
+
+按“业务域 → 对象或场景 → 文案用途”组织；文件按业务域划分，不对应组件目录。
+当前只建立实际使用的 common.json，不预建空业务包。
+
+| 业务域      | 内容                                             |
+| ----------- | ------------------------------------------------ |
+| common      | 无业务含义的操作、基础校验、界面偏好和通用错误页 |
+| auth        | 登录、退出、找回密码、身份认证                   |
+| navigation  | 导航菜单、面包屑、浏览器页面标题                 |
+| application | 智能体创建、配置、发布、版本                     |
+| knowledge   | 知识库、文档、分段、问题、标签、检索             |
+| model       | 模型、供应商、模型参数与连接测试                 |
+| tool        | 工具、MCP、Skill 管理                            |
+| workflow    | 画布、节点、变量、调试与执行展示                 |
+| chat        | 对话输入、消息操作、历史会话与对话状态           |
+| workspace   | 工作空间、成员、空间级设置                       |
+| system      | 用户、角色、系统配置、许可证                     |
+
+业务域内按实际对象拆分，如 knowledge.document；末级按用途使用：
+`title`、`description`、`actions`、`fields`、`validation`、`messages`、`dialogs`、
+`states`、`options`、`empty`。fields 内使用字段名下的 label、placeholder、description。
+common.errors 用于通用错误场景，例如 common.errors.notFound.description。
+
+归属以业务含义判断：知识库检索模式归 knowledge，知识库检索节点归 workflow。
+系统资源管理复用原业务域，不复制到 system。多处使用不等于通用；相同中文但业务语义
+不同可以使用不同 key。用户内容、提示词、协议枚举和已保存节点名称不进入语言包。
+
+## 使用约定
+
+- key 使用表达业务含义的英文 camelCase，不使用中文、数字序号或 misc 等模糊分类。
+- JSON 文件不重复包裹业务域，由 index.ts 挂载命名空间；各语言保持相同 key 与插值参数。
+- 完整句子整体翻译，动态内容使用命名参数；不用片段拼接句子。
+- 组件显式导入 useI18n，并使用全局作用域的 t；不使用自动注入的 $t。
+- 依赖语言的选项和校验规则在 computed 或执行时翻译，不在模块初始化时固化翻译结果。
+- 新增业务包时更新 index.ts 的所有语言及 MessageSchema，以中文结构约束翻译 key。
+- 非组件代码通过调用方传入翻译能力，不依赖某个入口的全局国际化单例。
+
+## 语言状态
+
+Admin 和 Chat 分别调用 createAppI18n，连接自己的 User Store；该模块不导入任何 Store。
+Store 是语言状态来源，通过 setLanguage 更新，不能直接修改 Vue I18n 的 locale。
+App.vue 通过当前 locale 配置 Element Plus，初始化同时维护 html.lang。
+
+两个入口继续共用 MaxKB-locale。初始化按本地缓存、浏览器语言、默认中文选择；
+英语变体归一为 en-US；zh-Hant、zh-TW、zh-HK、zh-MO 归一为 zh-Hant，
+显式 zh-Hans 优先使用简体，其余语言回退 zh-CN。Element Plus 的繁体映射为 zh-tw。Admin 加载账号后继续采用账号语言。
+跨标签页缓存变化同步到当前 Store。请求头复用原请求层的 user.language。
+当前语言选择只保存本地，不写回账号；账号偏好优先级在账号设置模块中处理。
+
+## 分批迁移
+
+404 页面为当前样例，提供简体、英文及繁体切换。其余界面、路由标题、编辑器及日期格式专项
+按模块接入，允许过渡期保留原中文。每批完成后等待用户检查，未经确认不扩展下一批。

+节点容器统一通过 `handleNodeWheel()` 隔离滚轮冒泡，保留下拉浮层等内部区域的原生滚动，避免画布处理滚轮并取消默认滚动。

 `component/NodeCascader.vue` 提供上游变量选择，已在内部统一管理下拉层的锚点保护，使用方无需重复接入。

 `true`，设为 `false` 可关闭自动校验。
