 | Flow | Source | Destination | Notes |
 |---|---|---|---|
+| Marketplace catalog and Account Library | Signed-in Renderer intent | bounded Host API → Main Marketplace client/cache → Works Square catalog, Library, resolve, Admission, and download APIs | Main binds requests to the current Account and response generation. Free acquisition changes only Account Library; it does not install, enable a project, assign an Agent Skill, or authorize runtime execution. |
+| Marketplace device installation | Account Library entry and explicit channel | Main resolve/Admission/download → descriptor/signature/archive/client compatibility verification → immutable Package Store index switch | Stable and explicit Beta remain distinct even when they resolve to the same immutable Release. Failed install/update retains the previous current release; explicit uninstall waits only for protecting worker/account references and completes after the final worker exits. |
+| Effective Plugin worker snapshot | Installed trusted package + project selection + Agent assignments + current server policy | effective resolver → Registry/resource loader/Extension Host/tool catalog → parent Pi worker | One frozen snapshot supplies Skills, tools, package roots, and runtime authorization. Disable, account/project switch, logout, Renderer crash, Main shutdown, or worker generation change invalidates future actions without mutating persisted unknown assignments; child workers receive no Plugin projection. |
 | 桌面认证生命周期 | Renderer 登录、刷新与注销请求 | Host API → Main Works Session → Works Square `/api/auth/{login,mobile-login,refresh,logout}` → one-feel auth | Main 加密持有并先持久化轮换 token；客户端不携带 OAuth client secret；连续 7 天未使用才清除会话，终止性 `400`/`401` fail closed |
 | 用户模块入口策略 | 会话恢复 / 登录 / 刷新 | Electron Main → Works `/api/auth/me` → 四布尔安全投影 → Renderer auth store → 卡片/路由/provider gate | 缺失对象或字段默认 `true`；`design` 映射 `painting`；终止性 `401` 清理 Main/Renderer 会话；全局 `/settings` 不受 Code gate |
 | 项目创建 | 新建项目对话框 | Host API → Main 项目初始化 | 创建时固定 `ProjectType`；小游戏/小程序原子生成受控模板，自定义只生成项目空间 |
