 - 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。

 - 2026-06-18 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。
