+- 背景：桌面壳 `network.status` 通过后台任务解析系统网络状态，H5 只需要稳定在线 / 离线语义；但后台任务 join 失败时，如果只返回稳定 `host_error`，开发侧无法区分正常离线、解析任务失败和系统异常。

 ## 2026-06-20 移动壳门禁脚本必须自登记自扫描
 
 - 背景：Expo 移动壳单端检查已把 `apps/mobile-shell/scripts/` 纳入生产源码扫描入口，但 `check-config.mjs` 自身仍被排除在脚本清单和替身词扫描之外；这会让移动壳与桌面壳门禁结构不一致，也可能让后续门禁反查内容绕过生产替身词规则。

 2026-06-18 追加：H5 账号状态刷新开始消费 `app.reloadWebView`。用户登录成功、退出登录、其它身份边界变化或登录状态异常页点击重新尝试时，`AuthGate` 会优先请求 Expo 壳刷新当前 WebView；宿主未声明或刷新失败时再回退浏览器刷新，避免在移动壳内绕过受控容器刷新入口。
 
 2026-06-18 追加：移动壳 WebView 内容 / 渲染进程终止时复用同一受控刷新路径。iOS `onContentProcessDidTerminate` 和 Android `onRenderProcessGone` 只调用当前 `react-native-webview` 的 `reload()`，不改写 H5 URL、不注入额外脚本、不新增宿主恢复页面，避免系统回收 WebView 进程后留下空白容器。
