+## 2026-06-20 桌面壳 HostBridge 事件注册失败不可静默
+
+- 背景：Tauri 桌面壳已经声明 `host.events`、`app.lifecycle`、`network.statusChanged` 和 `navigation.canGoBack`，H5 会据此订阅生命周期、网络和返回栈事件；如果 WebView 事件脚本注册失败仍被静默忽略，H5 会误以为宿主能力可用。
+- 决策：桌面壳启动阶段安装 `network.statusChanged` 和 `navigation.canGoBack` 脚本失败时直接阻断启动；生命周期首发和页面加载重放阶段的 `app.lifecycle`、`network.statusChanged`、`navigation.canGoBack` 失败必须通过统一 helper 记录日志，不允许 `let _ = register_desktop_*` 或 `let _ = emit_current_*` 静默吞错。配置检查反查该错误处理路径。
+- 影响范围：`apps/desktop-shell/src-tauri/src/app.rs`、`apps/desktop-shell/src-tauri/src/shell/lifecycle.rs`、`apps/desktop-shell/scripts/check-config.mjs`、宿主壳能力统一协议文档。
+- 验证方式：`cargo test --manifest-path apps/desktop-shell/src-tauri/Cargo.toml`、`npm run check:native-shells`、`npm run check:encoding`、`git diff --check`。

 - `subscribeHostAppLifecycle()`：原生 App 宿主的受控生命周期事件入口。Expo 移动壳和 Tauri 桌面壳都声明 `host.events`，表示宿主会通过 HostBridge message 派发事件；其中 Expo 移动壳通过 React Native `AppState` 派发 `app.lifecycle`，Tauri 桌面壳通过主窗口 focus / blur、托盘隐藏 / 恢复和页面加载重放派发同名事件。桌面壳不会把 hidden、minimized 或 tray 扩成新的 `state`，而是读取 `is_visible()`、`is_minimized()`、`is_focused()` 后统一归一为 `active` / `inactive` / `background`，并只把 `hidden`、`minimized`、`focused`、`blurred` 放进 `nativeState` 用于排障。`host.events` 不作为 request method，也不开放 Tauri event 插件或 React Native 私有事件 API。H5 只依赖统一的 `active` / `inactive` / `background` 状态和 `focused` 布尔值，原生细分状态只放在 `nativeState` 用于排障，不作为业务分支依据。H5 统一通过 `useHostLifecycleActive()` 把宿主状态折算为运行态可播放状态；WebAudio 背景音乐和固定玩法 `<audio>` 背景音乐都必须按该状态暂停 / 恢复，宿主进入后台、inactive 或窗口失焦时暂停，回到 active 且 focused 后只在原运行态、音源和用户音量仍允许时恢复。
 - `getHostNetworkStatus()` / `subscribeHostNetworkStatusChange()`：原生 App 宿主的受控网络状态入口。Expo 移动壳通过 `expo-network` 查询并订阅真实系统网络状态；Tauri 桌面壳从 `WEB_APP_ORIGIN` 解析主站 host / port 后按共享契约 `HOST_BRIDGE_DESKTOP_NETWORK_CHECK_TIMEOUT_MS` 做短超时 TCP 可达性查询，并在主 WebView 内监听 `online` / `offline` 注入变化事件。H5 只依赖统一的 `isConnected`、`isInternetReachable` 和连接类型，不直接读取平台私有网络 API。平台外部生成队列概览通过 `useHostNetworkOnline()` 消费该状态，宿主未声明网络能力时保持原轮询行为，宿主明确离线或不可达时暂停轮询，恢复在线后重新刷新；该状态不替代后端队列事实或生成结果回读。
 - `subscribeHostNavigationCanGoBack()` / `useHostNavigationCanGoBack()`：原生 App 宿主的受控返回栈状态入口。H5 只有在宿主同时声明 `host.events` 和 `navigation.canGoBack` 时才订阅该事件；Expo 移动壳和 Tauri 桌面壳注入的状态只表示当前 H5 文档路由栈或宿主已归一后的返回状态，不让 H5 读取任意原生 back-forward list。主 App 在原生壳内直达非平台首页、非 runtime 的二级 H5 route 且当前 history state 没有应用导航标记时，会先把当前条目替换为 `/` 返回锚点，再把当前路径连同已保留的宿主 query 推回 history；普通浏览器、小程序、runtime 路由、已有应用 history 或不支持返回栈事件的裁剪壳不触发该补齐。
+  声明 `host.events`、`app.lifecycle`、`network.statusChanged` 或 `navigation.canGoBack` 后，宿主壳必须把对应 WebView 事件脚本注册失败显式失败或记录日志；启动阶段无法安装网络 / 返回栈事件时不得继续以半可用状态运行，页面重放阶段不得静默吞掉失败。
