+
+`nativeSubscribe` 和 Toast 都由主应用宿主提供。插件不应复制主程序订阅弹窗，也不应自行创建另一套 Toast 容器。插件在旧版主程序或能力不存在的环境中运行时，应保留空值判断和必要的页面内 fallback。
+
+### 5.6 调用主应用原生订阅
+
+`Page`、`Config`、`Dashboard` 与 `AppPage` 都会收到 `nativeSubscribe(mediaInfo)` prop。插件传入媒体信息后，电视剧会打开主应用的选季抽屉，电影会进入现有电影订阅流程。宿主也会用 `moviepilot:nativeSubscribe` 键提供同一个方法，深层子组件可以使用 `inject`，无需逐层传递 prop。
+
+媒体信息必须包含：
+
+- `type`：`电影` / `电视剧`，也兼容 `movie` / `tv`；
+- `title`；
+- 至少一个有效媒体标识：`tmdb_id` / `tmdbid`、`douban_id` / `doubanid`、`bangumi_id` / `bangumiid`、`anilist_id` / `anilistid`，或者 `media_id` 与 `mediaid_prefix` / `source` / `media_source` 的组合。
+
+```vue
+<script setup lang="ts">
+import { inject } from 'vue'
+
+type NativeSubscribeResult =
+  { success: true } | { success: false; code: 'INVALID_MEDIA' | 'PERMISSION_DENIED'; message: string }
+
+const props = defineProps<{
+  nativeSubscribe?: (mediaInfo: Record<string, unknown>) => Promise<NativeSubscribeResult>
+}>()
+
+const nativeSubscribe = inject('moviepilot:nativeSubscribe', props.nativeSubscribe)
+
+/** 使用主应用订阅交互，宿主不接受时保留插件自己的 fallback。 */
+async function subscribeMedia(mediaInfo: Record<string, unknown>) {
+  const result = await nativeSubscribe?.(mediaInfo)
+  if (!result?.success) {
+    // 插件可在这里执行自己的 fallback；宿主已同时显示明确错误提示。
+  }
+}
+</script>
+```
+
+`success: true` 表示主应用已接受调用并启动原生交互，不表示用户已经完成订阅。字段无效或当前用户没有订阅权限时返回 `success: false`，插件可以依据 `code` 执行 fallback。
+
+### 5.7 调用主应用 Toast
 
 `Page`、`Config`、`Dashboard` 与 `AppPage` 的宿主容器会通过固定键提供主应用 Toast。远程组件应复用该实例，不要自行渲染 `VSnackbar` 或创建另一套 Toast 容器：
