 **错误怎么传播？** 业务 crate 用 thiserror → AppError → Axum IntoResponse 自动转 HTTP。详见 [[erp-core]] 错误处理链。
 
-**为什么没有路由？** Phase 1 只搭建基础设施。ModuleRegistry 已定义但未集成到 [[erp-server]]，Phase 2 开始注册路由。
+**状态如何共享？** AppState 包含 DB、Config、EventBus、ModuleRegistry，通过 Axum State 提取器注入所有 handler。
+
+**ModuleRegistry 怎么工作？** 每个 Phase 2+ 的业务模块实现 ErpModule trait，在 main.rs 中链式注册。registry 自动构建路由和事件处理器。
 
 **版本差异怎么办？** package.json 使用 React 19 + Ant Design 6（比规格文档更新），以实际代码为准。
