 ## 已完成关键能力
 
+- **05-18 / dev SPA 全套 UI 中文化**:用户反馈"web 页面菜单按钮啥的改为中文"。`web/static/dev.html` 静态部分(login overlay / header / 三栏 pane-head label / chat 操作按钮 / new task modal)+ JS 动态部分(状态文案 / role 标签 / confirm/alert 文案 / 状态 badge / SSE 流式提示)全面本地化。**静态文案**:`zcbot dev login → zcbot 登录` / `+ new task → + 新建任务` / `logout → 退出登录` / `tasks/chat/files → 任务/对话/文件` / 状态 select `(all)/active/completed/abandoned → (全部)/进行中/已完成/已废弃` / `export .docx/done/abandon/delete → 导出 docx/完成/废弃/删除` / `stop/send → 停止/发送` / `ready/sending/streaming/cancelling → 就绪/发送中/接收中/停止中` / `(no task selected) → (未选中任务)` / `select a task on the left → 请在左侧选一个任务` / `loading… → 加载中…` / `load failed → 加载失败` / `(no tasks) → (暂无任务)` / `(no messages yet) → (暂无消息 · 在下方输入开始对话)` / `(unnamed) → (未命名)` / `(user root) → (根目录)`。**动态文案**:`renderTaskList` / `renderChatMeta` 加 `statusLabels` map(`active→进行中`等),task list 计数 `msg → 条`;消息卡 role 标签 `user/assistant/error → 我/助手/错误`,`tool · name → 工具调用 · name`,`result (N chars) → 结果(N 字符)`,SSE 流式 `tool_call:/tool_result → 工具调用:/工具结果`;`cancelled` badge `已停止(stopped by user) → 已停止`(更简洁)。**弹窗 / 错文案**:`确认置为 status? → 确认置为「中文 label」?` / `delete failed → 删除失败:` / `download failed → 下载失败:` / `upload failed → 上传失败:` / `export failed → 导出失败:` / 删 task confirm 文案改"任务「项目名」(N 条消息)" / `任务名 必填 → 任务名为必填项`。**modal**:`新建 task → 新建任务` / 各 label "必填"/"可选" 加括号统一 / `留空 fallback 用任务名 → 留空则用任务名` / `N 个 task → N 个任务`。**Smoke**(in-process TestClient 拉 `/static/dev.html`):assert 13 个中文标签全在 + 8 个原英文按钮文案全无残留。**没动**:技术字段(`user_id` / `platform_key` / `UUID` / `tok` token 简称)、CSS class(`badge active` 等仍是英文 class,但显示文本走 statusLabels)、SSE event 名(`text/tool_call/tool_result/done/error/cancelled`)、API 字段名 — 都是 schema 层,不影响 UI 中文。
