- use-app-actions.test.tsx 缺失 @vitest-environment jsdom
- 所有 TS/TSX 文件 Prettier 格式化统一

配置更新:
- vitest.config.ts — v8 覆盖率 + 阈值门禁 (60%/70%)
- package.json — format/format:check/test:coverage/prepare 脚本 + lint-staged
- .gitignore — 新增 coverage/sync-conflict/playwright-report
- README.md — 新增 coverage + platform 徽章 + 截图区域

 ## 关键约束
 
 - **TypeScript**：`strict: true`，零编译错误
-- **Rust 工具链**：`stable-x86_64-pc-windows-gnu`（`rust-toolchain.toml` 强制）
+- **Rust 工具链**：`stable-x86_64-pc-windows-gnu`（项目已设 override）
 - **MinGW 兼容**：`.cargo/config.toml` 添加 `-lmcfgthread`（GCC 15.2.0 运行时）
 - **运行权限**：需要管理员权限才能编辑系统 PATH，非管理员自动进入只读模式
 - **构建产物**：NSIS 安装包，约 8MB

 PathEditor v5.0 是一个功能完善的 Windows 系统环境变量 (PATH) 编辑器，支持 GUI 与 CLI 双模式。

 ## 2. 架构设计审查
 
 ### 2.1 Cargo Workspace 三层架构
+
 项目采用了经典的 Cargo Workspace 模式，分为三层：
+
 - `core`: 纯 Rust 库 crate，包含所有的核心业务逻辑（注册表读写、备份、配置文件管理、路径验证与清理等）。该层**完全不依赖** Tauri 或 CLI 库，极大地提高了代码的复用性和可测试性。
 - `gui`: Tauri 桌面应用。仅作为薄包装层（Thin Wrapper），通过 `#[tauri::command]` 将 `core` 的功能暴露为 IPC 接口供前端调用。
 - `cli`: 命令行工具层。依赖 `core` 和 `clap` 库，直接提供命令行交互能力。
@@ -21,13 +24,16 @@ PathEditor v5.0 是一个功能完善的 Windows 系统环境变量 (PATH) 编
 **审查结论**：架构设计非常优秀。核心逻辑解耦彻底，无论是 GUI 还是 CLI 都能复用同一套安全、经过测试的核心代码。
 
 ### 2.2 IPC 通信与状态同步
+
 前端与 Rust 后端通过 Tauri IPC 进行通信。
+
 - 所有的错误处理均通过 `Result<T, String>` 返回，前端通过 `Promise` 捕获并处理，用户体验良好。
 - 针对非事务性的双写操作（如同时保存系统和用户 PATH），前端 `app-store.ts` 中使用了 `Promise.allSettled`。当发生部分成功（Partial Success）时，能正确捕获并重新加载注册表状态，避免了前端内存状态与后端注册表状态的漂移（State Drift）。
 
 ## 3. 后端代码审查 (Rust)
 
 ### 3.1 核心逻辑 (`core`)
+
 - **安全性与健壮性**：
   - 在 `registry.rs` 中，严格检查了路径字符串的 Null 字节，以及 32767 个字符的 Windows 注册表长度上限，防止缓冲区溢出或写入失败。
   - 使用了安全的 `winreg` 库进行注册表操作。

   - 能够妥善处理 UTF-16 编码和解码，保留非法码点避免丢失路径信息，细节处理非常到位。
 
 ### 3.2 命令行工具 (`cli`)
+
 - **原子性与并发安全**：
   - 在 CLI 的 `verify_and_save` 逻辑中，写入前会重新读取注册表并与原始状态对比。如果不一致，则拒绝写入并报错退出。这有效地防止了并发情况下的配置覆盖问题。
 - **用户体验**：

 ## 4. 前端代码审查 (React + TypeScript)
 
 ### 4.1 状态管理 (`app-store.ts`)
+
 - 使用 `Zustand` 进行全局状态管理，状态树设计合理，避免了 React Context 可能带来的不必要重渲染。
 - 实现了完善的 `UndoRedoManager`，将每一步操作抽象为 `OperationType`，支持撤销/重做功能，这对于编辑器类应用来说是核心体验的加分项。
 - `isSaving` 状态守卫有效防止了用户双击保存按钮引发的并发竞争。
 
 ### 4.2 UI 与逻辑分离
+
 - 业务逻辑抽象到 `src/core` 目录下（如 `path-manager.ts`, `validation.ts`），UI 组件仅负责渲染和事件绑定。
 - `useAppActions.ts` 钩子巧妙地将组件层与 Store 状态操作解耦，使得组件代码极其整洁。

    如果 PATH 环境变量条目非常多（虽然实际场景中一般在 100 条以内），React 渲染完整列表可能会有微小延迟。当前规模下无影响，但若未来考虑显示大量工具链路径扫描结果，可引入虚拟列表（Virtual List）。
 
 ## 总结
+
 PathEditor v5.0 的代码库是一个优秀的 Rust + Tauri + React 实践范例。它具有清晰的三层架构、严格的类型和边界检查、以及良好的错误处理机制，整体架构稳健且易于长期维护。
