 - 背景：桌面壳应用菜单、托盘菜单和单实例唤醒是生产用户恢复、刷新和导航主窗口的宿主入口；如果这些动作失败仍被 `let _ = ...` 静默忽略，用户会看到菜单、托盘或二次启动无反应且无法排查。
 - 决策：应用菜单显示、后退、前进、刷新主窗口，托盘显示、刷新主窗口，以及单实例唤醒主窗口动作失败必须走统一桌面宿主事件日志；配置检查拒绝这些入口继续对主窗口动作使用 `let _ = ...` 静默吞错。
+- 2026-06-21 调整：托盘注册失败日志只记录 `desktop tray registration failed` 固定标签，不输出 Tauri tray 插件错误详情；配置检查拒绝重新拼接 `: {error}`。

 - 验证方式：`cargo test --manifest-path apps/desktop-shell/src-tauri/Cargo.toml`、`npm run desktop-shell:typecheck`、`npm run check:native-shells`、`npm run check:encoding`、`git diff --check`。

 - 桌面深链只作为宿主启动 / 唤醒入口处理，不进入 HostBridge capability，也不把 deep-link 插件 command 授权给 H5。Tauri 只注册 `genarrative` scheme，并接受同源 `https://app.genarrative.world` URL；壳层会把目标路径归一为带 `native_app`、`tauri_desktop` 和真实 capability 清单的同源 H5 URL，外域、明文协议和危险协议直接丢弃。`navigation.openNativePage` 的同源主动跳转也必须复用同一宿主上下文补写逻辑，避免新页面按普通浏览器运行态启动。
 - 桌面窗口状态持久化属于宿主壳自有体验，不进入 HostBridge capability，也不开放窗口状态插件 command 给 H5。Tauri 壳只保存主窗口大小、位置和最大化状态，不保存可见性、全屏或装饰状态，避免托盘隐藏窗口后下次启动被恢复成隐藏状态；`shell/window_state.rs` 必须保留 Rust 单测证明这组 flags 边界。
