# 资产 AI 问数 Demo
入口：本地运行 `npm run dev` 后打开 `http://localhost:3000/asset#assets`，点击「AI 问数」。
## 已实现
- 采用 Beautiful UI Thinking / Prompt Bar / Chat 的视觉语言；Thinking 步骤改为后端 SSE 实际查询进度，保留 MIT 许可于 `docs/licenses/beautiful-ui.txt`。
- DeepSeek Flash 将自然语言和上一轮查询计划转成受校验的结构化查询；后端复用资产仓储、权限过滤和业务分类；第二次模型调用只解释汇总数据。
- 查询当前资产数量、库存、可运营/待运营、运营率、异动和待交车；按区域、城市、车型、型号、部门和运营状态分组。
- 查询最多 93 天的交车、还车、替换趋势。交车包含替换；流转按业务车次计数，不以车辆去重。
- 图表/统计表/明细切换、分组下钻、明细搜索及分页、CSV 导出、连续追问、取消、错误重试、新对话、深浅主题及移动端。
- 浏览器 SpeechRecognition 语音输入：用户点击麦克风启动，转写后可编辑再发送。不支持或拒绝授权时提示文字输入。
## 本机配置
`DEEPSEEK_API_KEY` 仅位于 Git 忽略的 `.env`，后端读取。客户端构建不包含密钥。无需配置 `VITE_` 密钥。更换临时密钥后重启后端。
现有开发环境本身已开启本地免登录；本次未改变该开关。问答路由挂在应用的认证中间件之后，未认证直接调用被拒绝。部署环境必须沿用正常认证配置。
模型接收问题、维度目录（区域/城市/车型/型号）、已校验的上一轮计划和汇总统计；不会主动发送车牌、VIN、客户或车辆明细。用户在提问中自行输入的文字会发送给模型。业务数据没有伪造或演示替换。
Portainer / Docker 部署见 [DeepSeek 环境变量注入](./portainer-deepseek.md)。
## 口径和边界
- 当前公司从资产页面继承，变更公司请关闭面板后选择公司；服务端执行账号权限与公司范围过滤。
- 资产来源为当前台账与现有服务端缓存，结果标记查询时间，不声称是历史库存快照。
- 分组与明细使用同一次查询返回的数据；区域按现有省市映射。
- 运营率 = 当前筛选车辆中的运营车辆 / 当前筛选车辆数。
- 历史库存、金额、成本、预测等暂不支持，助手应说明能力范围或追问，不执行模型生成的 SQL。
- 会话只保存在打开的面板内，刷新/关闭不会保存。语音依赖浏览器和其在线识别服务，尚未接专用 ASR。
## 验证
- TypeScript 检查、Vite 生产构建；构建仍有现有 ECharts/AG Grid 大块提示。
- 自动验证个人权限与所属公司范围、库存子集计数、无认证拒绝、非法查询/日期拒绝，以及模型请求不包含车辆明细。
- 桌面及手机浏览器实际查询：库存 291 台 → 追问可运营库存 181 台；华东库存 198 条明细与分页对应。
- 2026-09-01 至 2026-09-23 流转：交车 63 车次、还车 69 车次，其中替换 19 车次；2026-09-22 下钻及 CSV 均为 17 条记录。
- 深浅模式、无横向页面溢出、空明细搜索和结果展示切换已验证。真实麦克风识别未自动录制测试。
开发大脑回执：DB-C-003，知识索引版本 1 校验通过，未发现冲突；本次是产品 Demo 实现，未形成新的跨任务复盘模式，无知识写入或 GitHub 同步。

assets 仅支持当前资产数量、运营数量、运营率（运营车辆/当前筛选车辆），库存包含可运营与待运营，异动与待交车是库存子集。filters 只允许 region/city/type/model/department 字符串包含匹配。type=车型如4.5T，model=具体型号。没有日期的资产查询必须省略 start/end。groupBy 默认为 region。flow 用于交车、退车、还车、替换趋势，固定 category=all、groupBy=none，默认本月1日至今天，日期范围最多93天，可以附加车辆属性 filters。图表/表格/明细选择 view，默认 chart，只有用户明确要求表格才用 table。
不支持金额、成本、收入、预测、历史库存快照、库存天数、跨期运营率和任意数据库操作；遇到不支持的指标、歧义、未知公司切换或用户要求超出能力，kind=clarify 并简洁解释。不要擅自用其他指标替代。当前公司范围由页面控制，不能通过计划改变。不要编造维度值。
