+### 配置 PDA 后端地址
+
+PDA 默认请求本机 `http://localhost:9099`，仅适用于后端运行在同一设备的本地开发。部署到独立 PDA 或局域网服务器时，在构建环境注入 `VITE_APP_BASE_API`：
+
+```bash
+VITE_APP_BASE_API=http://<服务器地址>:9099 pnpm run build:h5
+```
+
+不要把包含真实凭据的环境文件或地址配置提交到仓库。
+
+PDA 测试模式、批次授权和失效回退规则请阅读[测试数据批次操作说明](../docs/test-data-batch-operations.md)。PDA 只允许选择后端返回的 ACTIVE 授权批次，退出登录会清除本地批次上下文。
