+| 层级 | 定义位置 | 作用域 | 提供者 | 特点 |
+|------|---------|--------|--------|------|
+| 全局 Provider | `main.dart` | 整个 App | `AuthBloc`（认证） | `.value()` 复用已有实例，App 存活期间一直存在 |
+| 主页 Provider | `default_view.dart` | 仅底部 Tab 页面 | `HomeIndexCubit`、`ServiceIndexCubit`、`ReportIndexCubit` | `create` 创建新实例，仅在主页存活期间存在 |
+
+**子 `MultiBlocProvider` 可以访问父 `MultiBlocProvider` 提供的内容**（tab 页面中 `context.read<AuthBloc>()` 依然有效），反过来不行（`AuthBloc` 里不能读取业务 Cubit）。
 
 项目未使用 DI 框架（如 get_it），而是采用 **手动注入** 方式。在 `main.dart` 的 `_MyAppState.initState()` 中集中创建核心单例，通过构造函数向下传递。
