+
+## 运行
+
+```powershell
+npm.cmd install --registry=https://registry.npmjs.org
+npm.cmd run android
+```
+
+Android 模拟器访问本机后端时，默认 API 地址为：
+
+```text
+http://10.0.2.2:8000/api/v1
+```
+
+## 当前工程边界
+
+- `src/app`：Expo Router 页面入口，已初始化首页、报销、审批、AI 助手、我的。
+- `src/shared`：API、登录态、状态映射、公共组件和 mock 数据。
+- `src/platform`：相机、相册、语音输入等平台能力。
+- `src/features`：后续承载复杂业务逻辑，避免页面文件继续膨胀。
+
+## 已接入能力
+
+- Android 权限：相机、麦克风、相册图片读取。
+- 相机/相册：`platform/camera/receiptCapture.ts`。
+- 语音录制占位：`platform/voice/voiceInput.ts`。
+- 请求缓存：`@tanstack/react-query`。
+- 轻量状态：`zustand`。
+- 安全存储：`expo-secure-store`。
+
+## 开发原则
+
+普通问答、票据预览和 AI 识别建议不自动保存草稿；只有用户明确点击保存、生成、继续提交或关联已有草稿，才进入持久化链路。

+# Welcome to your Expo app 👋
+
+This is an [Expo](https://expo.dev) project created with [`create-expo-app`](https://www.npmjs.com/package/create-expo-app).
+
+## Get started
+
+1. Install dependencies
+
+   ```bash
+   npm install
+   ```
+
+2. Start the app
+
+   ```bash
+   npx expo start
+   ```
+
+In the output, you'll find options to open the app in a
+
+- [development build](https://docs.expo.dev/develop/development-builds/introduction/)
+- [Android emulator](https://docs.expo.dev/workflow/android-studio-emulator/)
+- [iOS simulator](https://docs.expo.dev/workflow/ios-simulator/)
+- [Expo Go](https://expo.dev/go), a limited sandbox for trying out app development with Expo
+
+You can start developing by editing the files inside the **app** directory. This project uses [file-based routing](https://docs.expo.dev/router/introduction).
+
+## Get a fresh project
+
+When you're ready, run:
+
+```bash
+npm run reset-project
+```
+
+This command will move the starter code to the **app-example** directory and create a blank **app** directory where you can start developing.
+
+### Other setup steps
+
+- To set up ESLint for linting, run `npx expo lint`, or follow our guide on ["Using ESLint and Prettier"](https://docs.expo.dev/guides/using-eslint/)
+- If you'd like to set up unit testing, follow our guide on ["Unit Testing with Jest"](https://docs.expo.dev/develop/unit-testing/)
+- Learn more about the TypeScript setup in this template in our guide on ["Using TypeScript"](https://docs.expo.dev/guides/typescript/)
+
+## Learn more
+
+To learn more about developing your project with Expo, look at the following resources:
+
+- [Expo documentation](https://docs.expo.dev/): Learn fundamentals, or go into advanced topics with our [guides](https://docs.expo.dev/guides).
+- [Learn Expo tutorial](https://docs.expo.dev/tutorial/introduction/): Follow a step-by-step tutorial where you'll create a project that runs on Android, iOS, and the web.
+
+## Join the community
+
+Join our community of developers creating universal apps.
