+## 2026-06-18 原生壳 WebView 刷新能力只保留受控当前页刷新
+
+- 背景：Expo 移动壳和 Tauri 桌面壳都需要一个真实的宿主级刷新入口，供 H5 在检测到资源、登录态或运行态需要重新载入时请求宿主刷新当前容器；该能力不能演变成任意 URL 导航或原生 WebView ref 透传。
+- 决策：新增 HostBridge method `app.reloadWebView` 和 H5 facade `reloadHostWebView()`。移动端只调用当前 `react-native-webview` 的 `reload()`，桌面端只调用 Tauri 主 `WebviewWindow.reload()`；该 method 不接受 payload，成功只表示宿主已发起刷新，刷新后当前 H5 上下文会卸载。继续把同源跳转留给 `navigation.openNativePage`，外链离开容器留给 `app.openExternalUrl`。
+- 影响范围：`packages/shared/src/contracts/hostBridge.ts`、`src/services/host-bridge/hostBridge.ts`、`apps/mobile-shell/`、`apps/desktop-shell/`、原生壳能力检查脚本和 HostBridge 架构文档。
+- 验证方式：`npm run check:native-shells`、`npm run typecheck`、`npm run check:encoding`、`git diff --check`。

 - `showHostLocalNotification()`：原生 App 宿主的受控即时本地通知入口。H5 只能传必填 `title` 和可选 `body`，两者都会去除首尾空白、折叠普通空白、限制长度并拒绝控制字符；Expo 移动壳通过 `expo-notifications` 请求通知权限、创建 Android 本地通知 channel 并立刻调度本地通知，Tauri 桌面壳通过 Rust 侧 `tauri-plugin-notification` 发送系统通知。该能力不包含远程推送、token 注册、定时提醒、后台远程通知或任意通知插件透传，宿主未声明、权限拒绝或系统失败时由 H5 视作失败并继续主流程。
 - `setHostAppTitle()`：原生 App 宿主的受控窗口标题入口。H5 主站会按当前平台阶段先同步 `document.title`，再通过 `app.setTitle` 请求宿主窗口标题同步；Tauri 桌面壳支持该能力，Expo 移动壳不声明时静默忽略。
 - `setHostAppBadgeCount()`：原生 App 宿主的受控应用角标入口。H5 只传 `0-99999` 的整数，`0` 表示清除角标；Expo 移动壳只在 iOS 声明 `app.setBadgeCount` 并通过 React Native `PushNotificationIOS` 设置应用图标角标，Android 不声明该能力；Tauri 桌面壳通过主窗口 `set_badge_count` 设置任务栏角标，底层平台不支持时返回明确错误，由 H5 视作失败并继续主流程。
+- `reloadHostWebView()`：原生 App 宿主的受控 WebView 刷新入口。H5 只能请求刷新当前承载主站的宿主 WebView；Expo 移动壳调用当前 `react-native-webview` 的 `reload()`，Tauri 桌面壳调用主 `WebviewWindow.reload()`。该能力不接受 payload，不开放任意 URL 导航、脚本执行、Tauri guest API 或 RN WebView ref；成功只表示宿主已发起刷新，刷新后当前 H5 上下文会卸载。
 - `openHostExternalUrl()`：原生 App 宿主的受控外链入口。H5 中需要离开主站的外链在 `native_app` 下先通过 `app.openExternalUrl` 请求宿主系统浏览器打开；只允许 `http:`、`https:`、`mailto:`、`tel:`，相对路径会先归一化到当前站点绝对 URL。宿主不可用或拒绝时回退浏览器外链行为，普通浏览器和小程序保持原有 `<a>` 语义。
 - `navigateHostNativePage()`：受控跳转宿主页，供订阅授权、支付、登录等 adapter 复用。Expo 移动壳首版只接受同源 H5 route 并切换 WebView URL；Tauri 桌面壳同样只接受 `https://app.genarrative.world` 同源 H5 route 并在主窗口内跳转。真正原生页面、登录和支付能力必须等对应 SDK / 页面接入后再声明支持。
 - `exportHostTextFile()`：原生 App 宿主的受控文本导出入口。Expo 移动壳通过 `file.exportText` 写入缓存文本文件并交给系统分享 / 保存面板；Tauri 桌面壳通过 `file.exportText` 打开系统保存对话框并写入用户选择的文件。文件名必须清洗，单次文本不超过 5 MiB，成功只返回文件名和字节数，不把本机绝对路径暴露给 H5；系统分享不可用或用户取消时返回明确错误，由 H5 fallback 承接。
