- 决策：`apps/desktop-shell/src-tauri/src/host_bridge/badge.rs` 和 `apps/desktop-shell/src-tauri/src/host_bridge/notifications.rs` 统一返回 `HostBridgeResponse`，各自承接 payload 校验、系统调用、成功响应和失败响应映射；`dispatch.rs` 只保留 method 委托。桌面壳配置检查会拒绝 `dispatch.rs` 重新对这两个 method 做 `match` 或包装 `ok(true)`。
- 影响范围：`apps/desktop-shell/src-tauri/src/host_bridge/badge.rs`、`apps/desktop-shell/src-tauri/src/host_bridge/notifications.rs`、`apps/desktop-shell/src-tauri/src/host_bridge/dispatch.rs`、`apps/desktop-shell/scripts/check-config.mjs`、`docs/project-memory/shared-memory/decision-log.md`。
- 验证方式：`npm run desktop-shell:typecheck`、`npm run desktop-shell:test`、`npm run check:native-shells`、`npm run check:encoding`、`git diff --check`。
## 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`。
