 - 背景：Tauri 桌面壳的外链打开、同源 H5 route 导航和 WebView reload 都直接影响原生壳内 H5 的完整流程；这些系统调用失败时，H5 只应得到稳定错误语义，但开发侧需要能区分外链打开失败、窗口导航失败、reload 失败和主窗口缺失。
 - 决策：`apps/desktop-shell/src-tauri/src/host_bridge/navigation.rs` 必须在外链打开失败、同源 H5 route 导航失败、WebView reload 失败和主窗口缺失时记录 `desktop navigation failed for ...` 日志。HostBridge 对 H5 仍只返回稳定 `external URL cannot be opened`、`native page unavailable` 或 `webview reload unavailable`，不透传系统错误、窗口内部信息或平台细节。
+- 2026-06-21 调整：桌面导航失败日志只记录 `desktop navigation failed for <stage>` 固定标签，不输出 opener、window.navigate、WebView reload 错误或主窗口缺失说明；配置检查拒绝 `navigation.rs` 重新拼接 `: {error}`、`&error.to_string()` 或把主窗口缺失文本传给日志函数。
 - 验证方式：`cargo test --manifest-path apps/desktop-shell/src-tauri/Cargo.toml host_bridge::navigation`、`npm run desktop-shell:typecheck`、`npm run check:native-shells`、`npm run check:encoding`、`git diff --check`。
