 - 兼容边界不变：`app.workflow.WorkFlowManager` 的类路径、Singleton identity、公开方法、事件监听和

+### 长期整改阶段 10：运行时 Facade 获取方式统一（2026-08-24）
+
+- API、CLI、Scheduler 和工作流动作原先同时存在显式 `get_*` 调用、Application 兼容类构造，以及
+  `get_plugin_manager as PluginManager` 的类形别名。canonical 宿主消费者现统一显式调用
+  `get_module_manager()`、`get_plugin_manager()` 和 `get_scheduler()`，不再把 Service Locator 伪装成
+  concrete 类构造。
+- 架构门禁扫描全部宿主 Python 源码，禁止重新导入 `app.application.module.ModuleManager`、
+  `app.application.scheduling.Scheduler`，或为插件 getter 建立别名。startup 仍负责创建 concrete
+  管理器并注册 provider，运行时实例身份、初始化顺序和依赖图边均不改变。
+- 兼容边界不变：Application 的 `ModuleManager`、`Scheduler` 类形 Facade 和 concrete 插件管理器类路径
+  继续保留，旧插件、V1/V2/V3 索引加载及 SDK/Compat 映射无需迁移；本阶段仅统一宿主生产路径。
+
 ### 总体判断
 
 当前架构总体合理，已经从跨层混合的遗留单体收敛为**边界清晰的模块化单体**：
