 - 2026-06-18 分享卡图片导出：新增 `file.exportImage` HostBridge capability，H5 分享卡下载在 native app 中优先把 canvas 生成的 base64 图片交给宿主导出；Expo 壳写缓存图片后交给系统分享 / 保存面板，Tauri 壳通过系统保存对话框写入图片字节。该能力只接受 `image/png` / `image/jpeg` / `image/webp`、单次 5 MiB 内图片数据，成功只返回文件名和字节数，不暴露本机绝对路径；宿主未声明时保留浏览器下载。
 - 2026-06-18 应用角标能力：新增 `app.setBadgeCount` HostBridge capability，H5 只传 `0` 到共享契约 `HOST_BRIDGE_BADGE_COUNT_MAX` 之间的整数并在宿主未声明时静默 fallback；Expo 壳只在 iOS 声明并通过 React Native `PushNotificationIOS` 设置应用图标角标，Android 不声明、不伪造成功；Tauri 壳通过主窗口 `set_badge_count` 设置任务栏角标，底层平台不支持时返回真实错误。
 - 2026-06-18 草稿生成未读角标：平台壳层把“可见作品架里未读的草稿生成完成更新”同步到 `app.setBadgeCount`；同一草稿的 work/profile/session 等多个恢复 ID 只计 1，已读、失败、生成中和不可见草稿不计入。该角标只消费已有 HostBridge 能力，宿主不支持或设置失败不影响 H5 红点、作品架或后端状态。
+- 2026-06-19 原生壳角标边界：Expo `app.setBadgeCount` 的 iOS 平台判定、共享上限校验和 `PushNotificationIOS.setApplicationIconBadgeNumber(...)` 调用统一收口在 `apps/mobile-shell/src/host-bridge/badge.ts`；Tauri `app.setBadgeCount` 的 payload 校验、清除语义和主窗口 `set_badge_count` 调用统一收口在 `apps/desktop-shell/src-tauri/src/host_bridge/badge.rs`。两端 `dispatch` 只负责委托对应 badge 模块和映射响应，配置检查会拒绝分发层直接导入角标底层 API 或重声明数量边界。
 - 2026-06-18 宿主外观只读查询：新增 `appearance.getColorScheme` HostBridge capability，Expo 壳通过 React Native `Appearance.getColorScheme()` 读取系统配色，Tauri 壳通过主窗口 `theme()` 读取窗口主题；该能力只返回 `light` / `dark` / `unknown`，不设置 H5 主题、不覆盖系统主题，也不作为强制 UI 样式入口。
 - 2026-06-18 原生壳生命周期事件：新增 `app.lifecycle` HostBridge capability，Expo 壳通过 React Native `AppState` 派发 `active` / `inactive` / `background`，Tauri 壳通过主窗口 focus / blur、托盘隐藏 / 恢复和页面加载重放派发统一状态；桌面隐藏到托盘或最小化都归一为 `background`，`hidden`、`minimized`、`focused`、`blurred` 只进入 `nativeState` 便于排障，不扩展共享 `state`。两端都声明 `host.events` 表示事件通过 HostBridge message 注入，但不把它作为 request method，也不开放 Tauri event 插件或 React Native 私有事件 API。H5 只通过 `subscribeHostAppLifecycle()` 订阅统一状态，后续游戏循环、音频和轮询暂停 / 恢复不得直接依赖 Expo / Tauri 平台细节。
 - 2026-06-18 原生壳网络状态：新增 `network.status` 与 `network.statusChanged` HostBridge capability，Expo 壳通过 `expo-network` 查询和订阅真实系统网络状态，Tauri 壳从 `WEB_APP_ORIGIN` 解析主站 host / port 后做短超时 TCP 可达性查询，并通过 WebView `online` / `offline` 注入变化事件；H5 统一使用 `getHostNetworkStatus()` / `subscribeHostNetworkStatusChange()`，不得直接读取 Expo / Tauri 私有网络 API。
