 - 背景：Tauri 桌面壳 `app.lifecycle` 事件会驱动 H5 游戏循环、背景音乐和固定玩法音频暂停 / 恢复；如果 `is_visible()`、`is_minimized()` 或 `is_focused()` 读取失败后静默使用默认值，生命周期状态可能错误且难以排查。
 - 决策：`emit_current_desktop_lifecycle_event(...)` 必须通过 `resolve_desktop_lifecycle_window_flag(...)` 读取窗口可见、最小化和焦点状态；读取失败时记录 `desktop host event failed for app.lifecycle.<field>`，再使用保守默认值。桌面壳配置检查拒绝重新出现 `window.is_visible().unwrap_or(...)`、`window.is_minimized().unwrap_or(...)` 或 `window.is_focused().unwrap_or(...)`。
+- 2026-06-21 调整：生命周期窗口状态读取失败和 `app.lifecycle` / `navigation.canGoBack` 等桌面宿主事件注入失败只记录固定阶段标签，不把 Tauri 错误详情写入可分发桌面壳 stderr；配置检查拒绝生命周期日志重新输出 `: {error}` 详情。
 - 影响范围：`apps/desktop-shell/src-tauri/src/shell/lifecycle.rs`、`apps/desktop-shell/scripts/check-config.mjs`。
 - 验证方式：`cargo test --manifest-path apps/desktop-shell/src-tauri/Cargo.toml shell::lifecycle`、`npm run desktop-shell:typecheck`、`npm run check:native-shells`、`npm run check:encoding`、`git diff --check`。

 2026-06-18 追加：桌面壳启用 Tauri 真实系统托盘，并复用品牌图标。托盘菜单只提供宿主壳级动作：显示主窗口、刷新主窗口和退出应用；左键点击托盘图标恢复并聚焦主窗口。该能力不进入 HostBridge capability 清单，不向 H5 暴露托盘 API、菜单 API、shell API 或任意窗口控制；如果当前桌面环境无法注册托盘，壳会继续启动主窗口。托盘注册成功时，用户点击主窗口关闭按钮会先通过 `app.lifecycle` 注入 `background` / `hidden`，再隐藏到托盘，必须通过托盘“退出”动作结束应用；托盘恢复、应用菜单显示、单实例唤醒和 deep link 唤醒都会重新显示、取消最小化、聚焦主窗口并回放当前生命周期状态。托盘注册失败时不拦截关闭，避免窗口消失后没有恢复入口；托盘显示和刷新主窗口动作失败必须记录桌面宿主事件日志，不能静默吞错。
