+独立域名入口将 `/` 代理至本应用静态容器根目录，或将构建目录内容直接发布到站点根目录；不再挂载 PDA 子路径。缺失资源返回 404，不回退首页，HTML 使用 `Cache-Control: no-store`。域名入口还须配置同源 API 代理：两端均将 `/gateway-api/` 转统一 Gateway `/api/`。入口须保留 Authorization，支持文件上传下载及至少 11m 请求体。域名与上游只在部署侧配置，不编入 PDA 源码。
 
 部署配置检查：`node --test tests/h5-deployment.test.mjs`。没有 Docker 运行时的本地合同检查不能替代目标主机 `docker compose config`、Nginx 启动与真实 HTTP 验收。
 
 构建后执行 `node scripts/verify-h5.mjs`，核对 HTML/JS/CSS 资源路径、同源 API 和无本机/旧海外配置泄漏。该检查与本地构建仅证明产物；TEST 页面登录、仓权限、业务操作和 Android 真机另行验收。
+
+### 两端统一 API 配置
+
+两端的 `VITE_API_BASE_URL` 均为统一 Gateway 绝对地址（含 `/api`）；`VITE_H5_API_BASE_URL=/gateway-api`；`API_PROXY_TARGET` 为同一 Gateway 源地址（不含 `/api`）。实际地址只放在未提交的 `.env.local`；修改后重启开发服务，发布前重新打包。
+
+两端独立域名入口均配置以下规则；`gateway:9000` 仅适用于同一 Docker 网络，其他部署须替换成实际统一 Gateway 上游。静态容器只提供页面文件，Vite 代理不会随静态包发布。
