 - Run 控制参考：借鉴 Harbour 的控制平面思想，只吸收 `run lifecycle`、activity/output stream、context bundle、kill/retry/resume 等本地运行治理能力；不引入 Harbour 的多租户后台、调度 UI、通用 shell workflow 或远程 runner 作为 v1 依赖。
 - 本地工程参考：借鉴 Godcoder 的本地产物 checkpoint / diff / restore、上下文安全过滤、轻量项目索引、项目级写锁和项目级权限策略；不引入通用 IDE 插件、云工作区或任意代码代理。
 - 代码组织：桌面客户端入口保持为薄组合层。前端把认证、Tauri 桥接、Runtime 配置、Agent Runtime 展示和项目摘要分别放入 `src/app`、`src/services` 与 `src/features`；Rust 项目能力和测试按功能域使用目录模块；界面测试与真实 Runtime E2E 使用薄 suite registry / entry 保留原执行顺序。后续拆分必须保持公开导出、命令契约、测试名称和行为不变，不能用 `include!`、整文件文本拼接或只移动到另一个超大文件代替真实模块边界。
+- 源码门禁：`check:native-shells` 等源码扫描必须跟随真实模块归属；入口组合层只验证受控组件的挂载关系，具体实现由所属模块单独验证。模块拆分后不得为了满足旧字符串扫描把实现搬回 `App.tsx`，也不得用跨文件文本拼接代替组件归属检查。
