+# Playwright 浏览器部署指南
+
+## 概述
+
+本文档为开发人员提供 ERPAuto 应用程序中 Playwright Chromium 浏览器的部署指南。文档说明如何将浏览器文件从开发机复制到目标用户机器，确保应用程序能够正常运行浏览器自动化任务。
+
+**重要提示**：部署前请先阅读 [BROWSER_VERSIONS.md](./BROWSER_VERSIONS.md) 了解版本信息。
+
+## 目标路径
+
+浏览器文件必须部署在以下路径：
+
+```
+%APPDATA%\erpauto\ms-playwright\chromium-1208\
+```
+
+完整展开路径示例（Windows）：
+
+```
+C:\Users\<用户名>\AppData\Roaming\erpauto\ms-playwright\chromium-1208\
+```
+
+## 目录结构
+
+部署完成后，目标目录结构应如下所示：
+
+```
+%APPDATA%\erpauto\ms-playwright\
+└── chromium-1208/
+    └── chrome-win/
+        ├── chrome.exe              # 浏览器可执行文件
+        ├── chrome_dll.dll
+        ├── resources/
+        ├── locales/
+        └── ...                     # 其他浏览器文件
+```
+
+**关键文件**：`chrome-win/chrome.exe` 必须存在，否则浏览器无法启动。
+
+## 部署步骤
+
+### 步骤 1：在开发机上准备
+
+1. 确保开发机已安装正确版本的 Playwright：
+
+   ```bash
+   npm install playwright@1.58.2
+   ```
+
+2. 下载 Chromium 浏览器：
+
+   ```bash
+   npx playwright install chromium
+   ```
+
+3. 定位开发机上的浏览器缓存目录：
+
+   ```
+   C:\Users\<开发机用户名>\AppData\Local\ms-playwright\chromium-1208
+   ```
+
+### 步骤 2：复制文件
+
+1. **复制整个浏览器目录**
+   - 将开发机上的 `chromium-1208` 目录完整复制
+   - 不要只复制部分文件，确保所有子目录和文件都包含在内
+
+2. **粘贴到目标路径**
+   - 在目标机器上创建目录：`%APPDATA%\erpauto\ms-playwright\`
+   - 将 `chromium-1208` 目录粘贴到该路径下
+
+3. **验证文件完整性**
+   - 确认目标路径存在：`%APPDATA%\erpauto\ms-playwright\chromium-1208\chrome-win\chrome.exe`
+   - 检查文件大小约为 280MB
+
+### 步骤 3：配置环境变量（可选）
+
+如需确保应用程序使用正确的浏览器路径，可设置以下环境变量：
+
+```batch
+set PLAYWRIGHT_BROWSERS_PATH=%APPDATA%\erpauto\ms-playwright
+```
+
+或在应用程序代码中设置：
+
+```javascript
+process.env.PLAYWRIGHT_BROWSERS_PATH = path.join(app.getPath('userData'), 'ms-playwright')
+```
+
+## 验证步骤
+
+部署完成后，执行以下验证步骤：
+
+### 验证 1：检查目录结构
+
+在目标机器上运行：
+
+```batch
+dir %APPDATA%\erpauto\ms-playwright\chromium-1208\chrome-win\chrome.exe
+```
+
+应显示文件存在。
+
+### 验证 2：启动浏览器测试
+
+运行 ERPAuto 应用程序，执行以下操作：
+
+1. 登录应用程序
+2. 进入「数据提取」页面
+3. 输入一个有效订单号
+4. 点击「开始提取」
+5. 观察浏览器是否正常启动并执行任务
+
+### 验证 3：检查日志
+
+查看应用程序日志，确认没有浏览器相关的错误信息：
+
+- 无 "browser not found" 错误
+- 无 "chromium revision not found" 错误
+- 无 "PLAYWRIGHT_BROWSERS_PATH" 相关警告
+
+## 故障排查
+
+### 问题 1：浏览器无法启动
+
+**症状**：应用程序报错，提示找不到浏览器或启动失败。
+
+**解决方案**：
+
+1. 确认修订号匹配（必须是 1208）
+2. 检查 `chrome-win/chrome.exe` 文件是否存在
+3. 验证 `PLAYWRIGHT_BROWSERS_PATH` 环境变量设置正确
+4. 确认目标机器具有相同的 Playwright 版本（1.58.2）
+
+### 问题 2：版本不匹配错误
+
+**症状**：应用程序启动时报出版本冲突错误。
+
+**解决方案**：
+
+1. 检查 `package.json` 中的 Playwright 版本是否为 1.58.2
+2. 确认复制的 Chromium 修订号为 1208
+3. 参考 [BROWSER_VERSIONS.md](./BROWSER_VERSIONS.md) 核对所有版本信息
+
+### 问题 3：权限不足
+
+**症状**：无法写入或读取浏览器目录。
+
+**解决方案**：
+
+1. 确保目标目录具有适当的读写权限
+2. 以管理员身份运行应用程序进行测试
+3. 检查防病毒软件是否阻止了浏览器执行
+
+### 问题 4：路径错误
+
+**症状**：应用程序在错误的位置查找浏览器文件。
+
+**解决方案**：
+
+1. 确认 `%APPDATA%` 环境变量指向正确的用户目录
+2. 检查应用程序是否正确解析了 `userData` 路径
+3. 在代码中硬编码浏览器路径进行调试
+
+## 注意事项
+
+- **仅部署 Chromium**：ERPAuto 只需要 Chromium 浏览器，不需要 Firefox 或 WebKit
+- **版本一致性**：开发机和目标机器的 Playwright 版本必须一致
+- **修订号匹配**：Chromium 修订号（1208）必须完全匹配，否则可能出现兼容性问题
+- **文件完整性**：复制时确保所有文件完整，损坏的浏览器文件会导致启动失败
+- **网络隔离环境**：目标机器如果无法访问互联网，必须提前部署浏览器文件，因为无法自动下载

+
+## Architecture Overview
+
+ERPAuto is an **Electron desktop application** for automating ERP system data processing. The application follows the classic Electron architecture with three distinct processes:
+
+### Process Structure
+
+1. **Main Process** (`src/main/`)
+   - Node.js environment managing application lifecycle
+   - Entry point: `src/main/index.ts`
+   - Registers all IPC handlers via `registerIpcHandlers()`
+   - Loads configuration from `config.yaml` via ConfigManager at startup
+
+2. **Preload Script** (`src/preload/`)
+   - Security bridge between main and renderer processes
+   - Exposes type-safe APIs via `contextBridge` as `window.electron` and `window.api`
+   - Central API surface organized by domain (auth, extractor, cleaner, database, etc.)
+
+3. **Renderer Process** (`src/renderer/`)
+   - React 19 + TypeScript UI
+   - Uses exposed preload APIs for all main process communication
+   - Authentication-based routing with role-based access control
+
+### Service Architecture
+
+The main process is organized around domain-specific services in `src/main/services/`:
+
+- **ERP Services** (`services/erp/`): Browser automation using Playwright
+  - `ExtractorService` - Downloads material plan data
+  - `CleanerService` - Deletes specified materials with dry-run support
+  - `ErpAuthService` - Handles ERP authentication
+  - `OrderResolverService` - Validates and resolves order numbers
+  - `locators.ts` - ERP element selectors
+
+- **Database Services** (`services/database/`): Dual database support
+  - `MySqlService` / `mysql.ts` - MySQL operations
+  - `SqlServerService` / `sql-server.ts` - SQL Server operations
+  - DAO pattern: `discrete-material-plan-dao.ts`, `materials-to-be-deleted-dao.ts`
+
+- **User Services** (`services/user/`): Authentication and session management
+  - `BipUsersDao` - User data access
+  - `SessionManager` - Active session tracking
+
+- **Other Services**:
+  - `config/` - Configuration management
+  - `excel/` - Excel file parsing
+
+### IPC Handler Pattern
+
+All IPC communication follows a consistent pattern:
+
+- Handlers are in `src/main/ipc/`, organized by domain (8 modules)
+- Each handler module exports a `register*Handlers()` function
+- All handlers are registered in `src/main/ipc/index.ts`
+- Channel naming follows `domain:action` convention (e.g., `extractor:run`, `auth:login`)
+
+### Authentication Flow
+
+The application implements a multi-stage authentication system:
+
+1. **Silent Login**: On startup, attempts automatic login using computer name
+2. **Fallback**: Shows login dialog if silent login fails
+3. **Admin User Selection**: Admin users can switch to other user accounts
+4. **Session Management**: Persistent sessions with role-based permissions (Admin/User/Guest)
+
+Admin users see logout buttons and can access user switching. Non-admin users have restricted access based on the user who initiated their session.
+
+### Type System
+
+- Separate TypeScript configs: `tsconfig.node.json` (main/preload) and `tsconfig.web.json` (renderer)
+- Types are co-located with features: `src/main/types/` contains domain-specific type definitions
+- The preload script exposes a typed API surface that's available in renderer
+
+### Path Aliases
+
+- `@renderer` → `src/renderer/src` (renderer process)
+- `@main` → `src/main` (main process, tests only)
+- `@services` → `src/main/services` (main process, tests only)
+- `@types` → `src/main/types` (main process, tests only)
+
+## Configuration Management
+
+The application uses a YAML-based configuration system (`config.yaml`) managed by `ConfigManager`:
+
+- **Development**: `config.yaml` in project root (easy to edit and version control)
+- **Production**: `config.yaml` in user data directory (AppData on Windows)
+
+Key configurations in `config.yaml`:
+
+- **ERP Settings**: URL (fixed infrastructure)
+- **Database**: MySQL and SQL Server connection configs (dual support)
+- **Paths**: Data directory and output file settings
+- **Extraction**: Batch size, verbosity, persistence options
+- **Validation**: Data source, batch size, match mode
+- **Order Resolution**: Database table and field names for order number lookup
+
+Note: ERP credentials (username/password) are stored in the database (`dbo_BIPUsers` table) per user, managed via the Settings UI.
+
+## Key Technologies
+
+- **Electron 39** - Desktop framework
+- **React 19** - UI framework
+- **TypeScript 5.9** - Type safety
+- **Playwright 1.58** - Browser automation for ERP interaction
+- **electron-vite + Vite 7** - Build tooling
+- **Zod** - Runtime validation
+- **Vitest** - Unit tests
+- **Playwright Test** - E2E tests

+# Playwright 部署说明
+
+## 浏览器路径问题修复
+
+### 问题描述
+
+应用启动时提示"浏览器文件未找到"，但浏览器文件已经放置在正确路径下。
+
+**原因**：Playwright 1.48+ 改变了浏览器目录命名规则：
+
+- **旧格式**：`chromium-win32/chrome.exe`
+- **新格式**：`chromium-1208/chrome-win64/chrome.exe`（revision 号可能不同）
+
+### 解决方案
+
+代码已更新为自动检测新旧两种格式，并显示当前目录内容以便调试。
+
+## 快速部署
+
+### 方法 1：使用 Playwright CLI（推荐）
+
+```bash
+# 在应用目录运行
+npx playwright install chromium
+```
+
+浏览器会自动下载并安装到正确位置：
+
+- **用户数据目录**：`%APPDATA%\erpauto\ms-playwright\`
+- **完整路径**：`C:\Users\pengq\AppData\Roaming\erpauto\ms-playwright\chromium-<revision>\chrome-win64\chrome.exe`
+
+### 方法 2：手动复制
+
+如果你已经有 Playwright 浏览器文件，可以复制到应用的用户数据目录：
+
+1. 找到现有浏览器文件（通常在 `%USERPROFILE%\AppData\Local\ms-playwright`）
+2. 复制到 `%APPDATA%\erpauto\ms-playwright\`
+3. 确保目录结构正确：
+   ```
+   ms-playwright/
+   ├── chromium-1208/
+   │   ├── chrome-win64/
+   │   │   └── chrome.exe
+   │   └── INSTALLATION_COMPLETE
+   └── chromium_headless_shell-1208/
+       └── ...
+   ```
+
+### 方法 3：使用 PLAYWRIGHT_BROWSERS_PATH 环境变量
+
+将浏览器文件放在共享位置，然后设置环境变量：
+
+```bash
+# 系统环境变量
+setx PLAYWRIGHT_BROWSERS_PATH "D:\shared\playwright-browsers"
+```
+
+或在应用启动脚本中设置。
+
+## 验证安装
+
+运行应用后，检查是否还有错误提示。如果没有浏览器错误，说明安装成功。
+
+你也可以在应用日志中查找：
+
+- `Found Chromium revision: chromium-1208` - 表示成功找到浏览器
+- `Playwright browser not found` - 表示未找到，会显示可用目录列表
+
+## 常见问题
+
+### Q: 显示"浏览器文件未找到"但文件确实在那里
+
+检查目录结构是否正确：
+
+```powershell
+# 查看当前目录内容
+Get-ChildItem $env:APPDATA\erpauto\ms-playwright
+
+# 检查 chrome.exe 是否存在
+Test-Path "$env:APPDATA\erpauto\ms-playwright\chromium-*/chrome-win64/chrome.exe"
+```
+
+### Q: 不同用户使用同一个浏览器文件
+
+使用环境变量 `PLAYWRIGHT_BROWSERS_PATH` 指向共享目录。
+
+### Q: 离线部署
+
+1. 在有网络的机器上运行 `npx playwright install chromium`
+2. 复制整个 `ms-playwright` 目录
+3. 在目标机器上设置 `PLAYWRIGHT_BROWSERS_PATH` 指向该目录
+
+## 下次构建
+
+只需运行：
+
+```bash
+npm run build:win
+```
+
+所有配置已保存，Playwright 模块和浏览器路径检查会自动处理。

+# ERPAuto 配置文件位置说明
+
+## 概述
+
+ERPAuto 根据运行环境自动选择配置文件的存储位置：
+
+- **开发环境**：项目根目录（方便编辑和版本控制）
+- **生产环境**：用户数据目录（AppData，安全且升级时保留）
+
+---
+
+## 配置文件位置
+
+### 1. 开发环境
+
+**适用场景**:
+
+- 开发和调试
+- 配置需要版本控制
+- 团队协作
+
+**配置文件位置**:
+
+```
+<项目根目录>\config.yaml
+```
+
+**示例**:
+
+```
+D:\Projects\ERPAuto\
+├── src\
+├── package.json
+├── config.yaml           # 开发配置
+├── config.yaml.backup    # 自动备份
+└── config.template.yaml  # 配置模板
+```
+
+**检测方式**:
+
+```typescript
+process.env.NODE_ENV === 'development' || !app.isPackaged
+```
+
+---
+
+### 2. 生产环境（安装版和便携版）
+
+**适用场景**:
+
+- 正式发布的应用
+- 配置需要在应用升级时保留
+- 多用户环境，每个用户独立配置
+
+**配置文件位置**:
+
+```
+Windows: C:\Users\<用户名>\AppData\Roaming\erpauto\config.yaml
+macOS:   ~/Library/Application Support/erpauto/config.yaml
+Linux:   ~/.config/erpauto/config.yaml
+```
+
+**示例**:
+
+```
+C:\Users\zhangsan\AppData\Roaming\erpauto\
+├── config.yaml           # 用户配置
+└── config.yaml.backup    # 自动备份
+```
+
+**检测方式**:
+
+```typescript
+app.isPackaged === true
+```
+
+---
+
+## 为什么生产环境使用用户数据目录？
+
+| 方案               | 配置位置        | 优点                                                                        | 缺点                                                                                 |
+| ------------------ | --------------- | --------------------------------------------------------------------------- | ------------------------------------------------------------------------------------ |
+| **用户数据目录** ✓ | AppData\Roaming | • 应用升级时配置保留<br>• 符合 Windows 规范<br>• 多用户隔离<br>• 配置不暴露 | • 路径较深，不易访问                                                                 |
+| **应用同目录** ✗   | .exe 同目录     | • 易于访问和编辑                                                            | • 应用升级时配置可能丢失<br>• 需要写权限<br>• 配置暴露在应用目录<br>• 多用户共享配置 |
+
+**我们的选择**：生产环境统一使用用户数据目录，确保：
+
+1. ✅ 应用升级时用户配置不会丢失
+2. ✅ 符合 Windows 应用规范
+3. ✅ 配置不暴露在应用目录，更安全
+4. ✅ 多用户环境下，每个用户有独立配置

+### 查看当前配置路径
+
+运行调试工具：
+
+```bash
+npx tsx src\main\tools\config-path-debug.ts
+```
+
+### 快速访问配置（Windows）
+
+```bash
+# 打开配置所在目录
+%APPDATA%\erpauto
+```
+
+### 备份配置
+
+```bash
+# 备份整个配置目录
+xcopy %APPDATA%\erpauto D:\Backup\erpauto-config /E /I
+```
+
+### 迁移配置
+
+从旧版本迁移：
+
+```bash
+# 使用迁移脚本
+npx tsx scripts\migrate-env-to-yaml.ts
+```
+
+---
+
+## 常见问题
+
+### Q: 便携版应用的配置为什么不放在 exe 同目录？
+
+**A**:
+
+- 放在 exe 同目录会导致应用升级时配置丢失
+- 便携版每次运行会解压到临时目录，无法持久保存配置
+- 使用用户数据目录（AppData）确保配置持久化
+
+### Q: 如何快速访问配置文件？
+
+**A**:
+
+- Windows: 按 `Win + R`，输入 `%APPDATA%\erpauto`，回车
+- 或在文件管理器地址栏输入 `%APPDATA%\erpauto`
+
+### Q: 多台电脑如何同步配置？
+
+**A**:
+
+1. 导出配置：`xcopy %APPDATA%\erpauto\config.yaml \\server\share\`
+2. 导入配置：`xcopy \\server\share\config.yaml %APPDATA%\erpauto\`
+
+或使用同步工具（OneDrive、坚果云等）同步配置目录。
+
+### Q: 配置文件损坏了怎么办？
+
+**A**:
+
+1. 删除 `config.yaml`
+2. 应用会自动创建新的默认配置
+3. 从 `config.yaml.backup` 恢复（如果存在）
+
+### Q: 开发环境下如何切换配置？
+
+**A**:
+
+- 直接编辑项目根目录的 `config.yaml`
+- 建议保留 `config.template.yaml` 作为模板
+- 将 `config.yaml` 加入 `.gitignore`，避免提交敏感信息
+
+---
+
+## 技术实现
+
+### ConfigManager 路径选择逻辑
+
+```typescript
+// 检测是否为开发环境
+const isDev = process.env.NODE_ENV === 'development' || !app.isPackaged
+
+if (isDev) {
+  // 开发环境：项目根目录
+  this.configPath = path.resolve(__dirname, '../../config.yaml')
+} else {
+  // 生产环境（安装版和便携版）：用户数据目录
+  this.configPath = path.join(app.getPath('userData'), 'config.yaml')
+}
+```

+    B --> K[遍历完成]
+    K --> L[返回合并后的对象]
+```
+
+## 5. 配置读取与使用模式
+
+### 5.1 环境变量直接读取模式
+
+各业务服务通过 `process.env` 直接读取配置：
+
+```mermaid
+graph LR
+    subgraph "环境变量读取点"
+        MAIN[main/index.ts<br/>dotenv.config]
+    end
+
+    subgraph "服务模块"

+    ENV --> BIP_DAO
+    ENV --> ORDER_RES
+    ENV --> EXTRACTOR
+    ENV --> CLEANER
+    ENV --> VALIDATION
+```
+
+### 5.2 ConfigManager 获取模式
+
+通过 IPC 层统一获取：
+
+```mermaid
+sequenceDiagram
+    participant UI as 设置界面
+    participant Preload as Preload 脚本
+    participant IPC as IPC Handler
+    participant CM as ConfigManager
+
+    UI->>Preload: window.api.settings.getSettings()
+    Preload->>IPC: ipcRenderer.invoke('settings:getSettings')
+    IPC->>IPC: SessionManager.getUserType()
+    IPC->>CM: getAllSettings()
+    CM->>IPC: SettingsData
+    IPC->>IPC: filterSettingsByUserType()
+    IPC-->>Preload: 过滤后的 SettingsData
+    Preload-->>UI: SettingsData
+```
+
+### 5.3 数据库配置工厂模式
+
+```mermaid
+graph TB
+    subgraph "配置创建"
+        GET_TYPE[getDatabaseType] -->|DB_TYPE env| TYPE_CHECK{数据库类型}
+        TYPE_CHECK -->|mysql| CREATE_MYSQL[createMySqlConfig]
+        TYPE_CHECK -->|sqlserver| CREATE_SQL[createSqlServerConfig]
+    end
+
+    subgraph "服务创建"

+        MYSQL_SVC --> CACHE[instances Map]
+        SQL_SVC --> CACHE
+        CACHE -->|返回已连接实例 | CLIENT[调用方]
+    end
+
+    CREATE_MYSQL --> CONNECT_MYSQL[service.connect]
+    CREATE_SQL --> CONNECT_SQL[service.connect]
+
+    CONNECT_MYSQL --> CACHE
+    CONNECT_SQL --> CACHE
+```
+
+## 6. 用户权限与配置访问控制
+
+### 6.1 用户类型与权限
+
+```mermaid
+graph TB
+    subgraph "用户类型 UserType"
+        ADMIN[Admin<br/>管理员]

+    end
+
+    SM_LOGIN --> USER
+    SM_SILENT --> USER
+    SM_SWITCH --> USER
+```
+
+### 6.2 配置过滤机制
+
+```mermaid
+flowchart TD
+    A[getSettings 请求] --> B[获取当前用户类型]
+    B --> C{用户类型判断}
+
+    C -->|Admin| D[返回全部配置]

+    C -->|Guest| G[返回空配置或只读配置]
+
+    D --> H[返回给 UI]
+    E --> H
+    G --> H
+```
+
+## 7. 配置修改白名单机制
+
+### 7.1 可编辑字段白名单
+
+```javascript
+const UI_EDITABLE_FIELDS: string[] = [
+  'erp.url',
+  'erp.username',
+  'erp.password'
+  // 可根据需要扩展
+]
+```
+
+### 7.2 白名单验证流程
+
+```mermaid
+flowchart TD
+    A[savePartialSettings 调用] --> B[遍历 settings 中的字段]
+    B --> C[构建字段路径 section.field]
+    C --> D{字段在白名单中？}
+    D -->|否 | E[添加到 invalidFields]
+    D -->|是 | F[继续检查下一字段]
+    E --> B
+    F --> B
+    B --> G{所有字段检查完成}
+    G --> H{invalidFields 为空？}
+    H -->|否 | I[返回错误<br/>包含不允许修改的字段]
+    H -->|是 | J[继续保存流程]
+```
+
+## 8. 数据库配置详解

+## 10. 订单号解析表配置
+
+### 10.1 配置结构
+
+```mermaid

+    DB_QUERY --> PRODUCTION_ID[productionID]
+    DB_QUERY --> ORDER_NUMBER[生产订单号]
+```
+
+### 10.2 默认配置示例
+
+```env
+DB_TABLE_NAME=productionContractData_26 年压力表合同数据
+DB_FIELD_PRODUCTION_ID=总排号
+DB_FIELD_ORDER_NUMBER=生产订单号
+```
+
+## 11. 配置持久化与备份机制
+
+### 11.1 保存流程
+
+```mermaid
+flowchart TD
+    A[saveAllSettings] --> B[设置写入 configCache]
+    B --> C[构建.env 文件内容]
+    C --> D[按分类组织配置<br/>ERP/数据库/路径/提取/校验/UI/执行]

+    F -->|是 | G[返回 true]
+    F -->|否 | H[返回 false]
+```
+
+### 11.2 备份与恢复流程
+
+```mermaid

+
+## 12. 配置系统初始化时序
+
+```mermaid

+    end
+
+    Main->>CM: initialize 按需加载
+```
+
+## 13. 关键代码模式
+
+### 13.1 环境变量读取模式
+
+```typescript
+// 直接读取 process.env
+const dbType = process.env.DB_TYPE?.toLowerCase()
+const mysqlHost = process.env.DB_MYSQL_HOST || 'localhost'
+const mysqlPort = parseInt(process.env.DB_MYSQL_PORT || '3306', 10)
+```
+
+### 13.2 ConfigManager 读取模式
+
+```typescript
+// 通过 ConfigManager 获取结构化配置
+const configManager = ConfigManager.getInstance()
+const settings = configManager.getAllSettings()
+const erpUrl = settings.erp.url
+const batchSize = settings.extraction.batchSize
+```
+
+### 13.3 部分保存模式
+
+```typescript
+// 只更新允许修改的字段
+const result = await configManager.savePartialSettings({
+  erp: {
+    url: 'http://new-url.com',
+    username: 'newuser',
+    password: 'newpass'
+  }
+})
+```
+

+## 15. 配置系统特点总结
+
+### 15.1 优点
+
+1. **集中化管理**: ConfigManager 单例模式统一管理所有配置
+2. **类型安全**: TypeScript 类型定义确保配置结构正确
+3. **权限控制**: 基于用户类型的配置访问和修改权限控制
+4. **备份恢复**: 自动备份机制防止配置丢失
+5. **双数据库支持**: MySQL 和 SQL Server 灵活切换
+6. **部分更新**: deepMerge 支持配置部分字段更新
+
+### 15.2 可扩展性
+
+1. **新增配置项**: 在 `.env.example` 添加 → `DEFAULT_SETTINGS` 定义 → `SettingsData` 类型 → `save` 方法输出
+2. **新增用户权限**: 扩展 `UserType` → 更新 `filterSettingsByUserType` 逻辑
+3. **新增白名单字段**: 在 `UI_EDITABLE_FIELDS` 数组添加路径
+
+### 15.3 注意事项
+
+1. 修改配置后需要重新加载 `.env` 文件使 `process.env` 生效
+2. 非白名单字段只能通过 `saveAllSettings` 或 `resetToDefaults` 修改
+3. 数据库服务使用单例缓存，配置变更需重启应用或手动重连
+4. ERP 配置变更需重启浏览器才能生效

+# BIPUsers 表 ERP 参数迁移指南
+
+## 概述
+
+本次迁移将 ERP 配置参数（`ERP_URL`, `ERP_USERNAME`, `ERP_PASSWORD`）从 `.env` 文件迁移到 `dbo_BIPUsers` 数据库表中，实现每个用户独立的 ERP 配置。
+
+## 迁移步骤
+
+### 步骤 1：连接到 MySQL 数据库
+
+使用你喜欢的 MySQL 客户端工具连接：
+
+**方式 A: MySQL 命令行**
+
+```bash
+mysql -h 192.168.31.83 -P 3306 -u remote_user -p'3.1415926Beeke' BLD_DB
+```
+
+**方式 B: MySQL Workbench / Navicat / DBeaver**
+
+- Host: `192.168.31.83`
+- Port: `3306`
+- Username: `remote_user`
+- Password: `3.1415926Beeke`
+- Database: `BLD_DB`
+
+### 步骤 2：执行迁移 SQL
+
+运行以下 SQL 脚本添加新字段：
+
+```sql
+-- ============================================
+-- BIPUsers 表迁移：添加 ERP 参数字段
+-- ============================================
+
+USE BLD_DB;
+
+-- 1. 添加 ERP_URL 字段
+ALTER TABLE dbo_BIPUsers ADD COLUMN IF NOT EXISTS ERP_URL VARCHAR(500) NULL COMMENT 'ERP 系统 URL';
+
+-- 2. 添加 ERP_Username 字段
+ALTER TABLE dbo_BIPUsers ADD COLUMN IF NOT EXISTS ERP_Username VARCHAR(255) NULL COMMENT 'ERP 用户名';
+
+-- 3. 添加 ERP_Password 字段
+ALTER TABLE dbo_BIPUsers ADD COLUMN IF NOT EXISTS ERP_Password VARCHAR(255) NULL COMMENT 'ERP 密码';
+
+-- 4. 验证字段已添加
+DESCRIBE dbo_BIPUsers;
+```
+
+**注意：** 如果你的 MySQL 版本不支持 `ADD COLUMN IF NOT EXISTS`，请使用：
+
+```sql
+USE BLD_DB;
+
+ALTER TABLE dbo_BIPUsers ADD COLUMN ERP_URL VARCHAR(500) NULL COMMENT 'ERP 系统 URL';
+ALTER TABLE dbo_BIPUsers ADD COLUMN ERP_Username VARCHAR(255) NULL COMMENT 'ERP 用户名';
+ALTER TABLE dbo_BIPUsers ADD COLUMN ERP_Password VARCHAR(255) NULL COMMENT 'ERP 密码';
+```
+
+### 步骤 3：初始化 ERP 配置
+
+将所有现有用户的 ERP 配置设置为当前 `.env` 中的值：
+
+```sql
+-- 更新所有用户的 ERP 配置
+UPDATE dbo_BIPUsers
+SET
+  ERP_URL = 'https://68.11.34.30:8082/',
+  ERP_Username = '在这里填写你的 ERP 用户名',
+  ERP_Password = '在这里填写你的 ERP 密码'
+WHERE ERP_URL IS NULL OR ERP_URL = '';
+```
+
+**请将上面的占位符替换为实际的 ERP 凭证！**
+
+### 步骤 4：验证迁移结果
+
+```sql
+-- 检查所有用户的 ERP 配置
+SELECT
+  UserName,
+  UserType,
+  ERP_URL,
+  ERP_Username,
+  CreateTime
+FROM dbo_BIPUsers
+ORDER BY UserName;
+```
+
+## 迁移后配置
+
+### 更新 .env 文件（可选）
+
+迁移完成后，`.env` 文件中的 ERP 配置将不再使用，但为了向后兼容可以保留：
+
+```bash
+# ERP 配置（已废弃，仅用于向后兼容）
+# ERP_URL=https://68.11.34.30:8082/
+# ERP_USERNAME=your_username
+# ERP_PASSWORD=your_password
+```
+
+### 在应用中配置用户 ERP 参数
+
+迁移完成后，每个用户可以通过应用界面配置自己的 ERP 参数：
+
+1. 登录应用
+2. 进入设置页面
+3. 配置个人 ERP 连接信息
+4. 测试连接
+5. 保存
+
+## 故障排除
+
+### 问题 1：字段已存在错误
+
+```
+Error: Duplicate column name 'ERP_URL'
+```
+
+**解决方案：** 字段已经存在，跳过添加步骤，直接执行步骤 3 初始化数据。
+
+### 问题 2：连接被拒绝
+
+```
+Error: Access denied for user 'remote_user'@'%'
+```
+
+**解决方案：** 检查数据库用户权限，确保 `remote_user` 有 `ALTER` 和 `UPDATE` 权限。
+
+### 问题 3：连接超时
+
+```
+Error: connect ETIMEDOUT
+```
+
+**解决方案：**
+
+- 检查网络连接
+- 确认 MySQL 服务器正在运行
+- 检查防火墙设置
+
+## 回滚方案
+
+如果需要回滚，可以删除新增的字段：
+
+```sql
+-- ⚠️ 警告：这将永久删除 ERP 配置数据
+ALTER TABLE dbo_BIPUsers DROP COLUMN ERP_URL;
+ALTER TABLE dbo_BIPUsers DROP COLUMN ERP_Username;
+ALTER TABLE dbo_BIPUsers DROP COLUMN ERP_Password;
+```
+
+## 完成确认
+
+迁移完成后，请确认以下事项：
+
+- [ ] 三个新字段已成功添加到 `dbo_BIPUsers` 表
+- [ ] 所有现有用户的 ERP 配置已初始化
+- [ ] 应用程序可以正常启动
+- [ ] 数据提取和物料清理功能正常工作
+
+---
+
+**迁移脚本文件：**
+
+- `src/main/services/user/migration/add-erp-params-to-bipusers-mysql.sql` - 完整 SQL 脚本
+- `src/main/services/user/migration/run-migration.ts` - TypeScript 自动迁移脚本（需要网络访问）

+## 使用指南
+
+### 数据提取功能
+
+**使用场景：** 从 ERP 系统批量下载多个订单的物料计划数据。
+
+**操作步骤：**
+
+1. 进入「数据提取」页面
+2. 在左侧输入框中输入订单号，每行一个：
+   ```
+   SC70202602120085
+   SC70202602120120
+   SC70202602120137
+   ```
+3. 设置批量大小（建议 100-500）
+4. 点击「开始提取」
+5. 等待提取完成，查看结果统计
+
+**提取结果说明：**
+
+- **下载文件数**：成功下载的 Excel 文件数量
+- **记录数**：提取的总记录数
+- **错误数**：失败的订单数量
+
+### 物料清理功能
+
+**使用场景：** 删除指定订单中的特定物料代码。
+
+**操作步骤：**
+
+1. 进入「物料清理」页面
+2. 输入订单号（每行一个）
+3. 输入要删除的物料代码（每行一个）
+4. **重要**：首次使用建议勾选「干运行模式」
+5. 点击「开始清理」
+6. 查看清理结果
+
+**干运行模式：**
+
+- 勾选后，系统仅预览将要删除的数据，不实际执行删除
+- 建议先用干运行模式确认数据正确
+- 确认无误后，取消勾选执行实际删除
+
+**清理结果说明：**
+
+- **处理订单数**：成功处理的订单数量
+- **删除物料数**：实际删除的物料数量
+- **跳过物料数**：未找到或跳过的物料数量
+- **订单详情**：每个订单的详细处理结果

+## 七、关键配置参数
+
+| 参数                 | 默认值 | 范围  | 说明                     |
+| -------------------- | ------ | ----- | ------------------------ |
+| `queryBatchSize`     | 100    | 1-100 | 每批查询的订单数量       |
+| `processConcurrency` | 1      | 1-20  | 并行处理的订单详情页数量 |
+| `dryRun`             | false  | -     | 预览模式，不实际删除     |
+| `headless`           | true   | -     | 后台模式，不显示浏览器   |
+| `MAX_RETRIES`        | 2      | -     | 失败订单最大重试次数     |
+
+## 八、错误处理最佳实践
+
+### 8.1 已实现的模式
+
+1. **分层错误收集**: IPC 层、服务层、重试层分别收集
+2. **错误聚合**: 所有错误最终汇总到 `CleanerResult.errors`
+3. **重试恢复**: 自动重试失败订单，成功后从错误列表移除
+4. **详细记录**: 每个订单的 `OrderCleanDetail` 包含独立错误列表
+5. **审计追踪**: `RetryAttempt[]` 记录每次重试的详细信息
+
+### 8.2 错误格式规范
+
+```typescript
+// 订单级别错误格式
+;`Order ${orderNumber}: ${errorMessage}`
+
+// 解析警告直接添加
+warnings.push(warningMessage)
+
+// 重试失败记录
+retryAttempts.push({
+  attempt: 1,
+  error: '具体错误消息',
+  timestamp: Date.now()
+})
+```

+
+- ✅ = 已收集到 errors 数组
+- ⚠️ = 仅记录日志，不加入错误列表
+- ❌ = 不收集（终止性错误或业务跳过）
+- N/A = 不适用
+
+### 覆盖率分析
+
+**总计错误点**: 52 个
+
+**覆盖情况**:
+
+- 完全收集 (✅): 43 个 (82.7%)
+- 静默处理 (⚠️): 3 个 (5.8%) - 资源清理类错误，不影响业务
+- 不收集 (❌): 9 个 (17.3%) - 终止性错误或业务规则跳过
+
+**结论**: 错误收集覆盖全面，所有影响业务结果的错误均被正确收集。资源清理类错误采用静默处理是合理的设计决策，不影响用户对执行结果的认知。
+
+## 十、总结
+
+物料清理模块的错误收集机制具有以下特点：
+
+1. **多层防护**: 从解析、执行到重试，每个阶段都有错误捕获
+2. **自动恢复**: 失败订单自动重试，成功后从错误列表移除
+3. **详细追踪**: 每个订单、每次重试都有详细记录
+4. **用户友好**: 前端清晰展示错误类型和统计信息
+5. **审计完整**: 所有操作记录到数据库和报告文件
+
+错误处理流程遵循"收集 → 尝试恢复 → 记录 → 报告"的模式，确保用户能够清楚了解每个订单的处理状态和失败原因。

+# CleanerPage User Scope Fix
+
+**Issue**: User users were affecting other users' data when using "取消" and "确认删除" buttons
+
+**Date**: 2026-03-03
+**Branch**: `fix/cleaner-user-scope`
+
+---
+
+## Problem Analysis
+
+### Bug Description
+
+For **User type (non-Admin)** users:
+
+1. The table shows only materials assigned to the current user (filtered by `filteredResults`)
+2. Clicking "取消" (Uncheck All) was unchecking **ALL** materials in `validationResults`, including invisible ones
+3. Clicking "确认删除" (Confirm Deletion) processed **ALL** materials in `validationResults`, not just visible ones
+4. This caused User A to delete User B's materials that User A never saw!
+
+### Root Causes
+
+#### 1. "取消" Button (Line 420)
+
+```typescript
+// ❌ WRONG: Clears ALL selected items
+onClick={() => setSelectedItems(new Set())}
+```
+
+#### 2. `handleConfirmDeletion` Function (Line 165)
+
+```typescript
+// ❌ WRONG: Iterates ALL validation results
+for (const result of validationResults) {
+  // Processes items user can't even see!
+}
+```
+
+### Data Flow
+
+```mermaid
+graph TB
+    subgraph "Backend"
+        A[validationResults<br/>1000 items] --> B[User Filter<br/>currentUsername]
+    end
+
+    subgraph "Frontend Display"
+        B --> C[filteredResults<br/>100 items visible]
+        C --> D[Table Display]
+    end
+
+    subgraph "Bug Behavior (BEFORE FIX)"
+        E[取消 Button] --> F[Clears selectedItems<br/>for ALL 1000 items ❌]
+        G[确认删除 Button] --> H[Processes ALL 1000 items ❌]
+        H --> I[Deletes User B's data ❌]
+    end
+
+    subgraph "Fixed Behavior (AFTER FIX)"
+        E2[取消 Button] --> F2[Clears only visible<br/>100 items ✅]
+        G2[确认删除 Button] --> H2[Processes only<br/>100 items ✅]
+        H2 --> I2[Only affects User A ✅]
+    end
+```
+
+---
+
+## Solution
+
+### Fix 1: "取消" Button - Only Uncheck Visible Items
+
+**File**: `src/renderer/src/pages/CleanerPage.tsx:419-432`
+
+```typescript
+<button
+  onClick={() => {
+    // Only uncheck items that are visible in filteredResults
+    const visibleCodes = new Set(filteredResults.map((r) => r.materialCode))
+    setSelectedItems((prev) => {
+      const newSet = new Set(prev)
+      for (const code of visibleCodes) {
+        newSet.delete(code)
+      }
+      return newSet
+    })
+  }}
+  className="text-xs bg-white border border-slate-300 text-slate-700 px-2.5 py-1.5 rounded shadow-sm hover:bg-slate-50 flex items-center gap-1"
+>
+  <Square size={14} className="text-slate-400" /> 取消
+</button>
+```
+
+**What Changed**:
+
+- Before: `setSelectedItems(new Set())` - clears everything
+- After: Iterates through `filteredResults` and removes only visible items from `selectedItems`
+- Preserves selections for items not currently visible (e.g., other users' data)
+
+### Fix 2: `handleConfirmDeletion` - Only Process Visible Items (Non-Admin)
+
+**File**: `src/renderer/src/pages/CleanerPage.tsx:158-222`
+
+```typescript
+const handleConfirmDeletion = async () => {
+  // For non-admin users, only process visible filtered results
+  // For admin users, process all validation results
+  const resultsToProcess = isAdmin ? validationResults : filteredResults
+
+  if (resultsToProcess.length === 0) return alert('没有可处理的数据')
+
+  const materialsToUpsert: { materialCode: string; managerName: string }[] = []
+  const materialsToDelete: string[] = []
+  const missingManager: string[] = []
+
+  for (const result of resultsToProcess) {
+    // ... rest of processing logic
+  }
+  // ...
+}
+```
+
+**What Changed**:
+
+- Before: `for (const result of validationResults)` - processes all 1000 items
+- After: `for (const result of resultsToProcess)` where:
+  - `Admin` → processes `validationResults` (all items)
+  - `User` → processes only `filteredResults` (visible items)
+
+---
+
+## Testing Scenarios
+
+### Scenario 1: User Unchecks Own Data Only
+
+**Setup**:
+
+- User A logs in (non-Admin)
+- 100 materials visible (assigned to User A)
+- 900 materials invisible (assigned to other users)
+- All 1000 materials are initially checked
+
+**Actions**:
+
+1. User A clicks "取消"
+2. Table shows all checkboxes unchecked
+
+**Expected**:
+
+- ✅ User A's 100 materials are unchecked
+- ✅ Other users' 900 materials **remain checked** (not affected)
+
+**Verification**:
+
+```typescript
+// Before fix: selectedItems.size === 0
+// After fix: selectedItems.size === 900 (other users' items still checked)
+```
+
+### Scenario 2: User Confirms Deletion
+
+**Setup**:
+
+- User A logs in (non-Admin)
+- User A unchecks 50 of their 100 materials
+- 50 items checked (User A's)
+- 900 items checked (other users')
+
+**Actions**:
+
+1. User A clicks "确认删除"
+2. Confirm dialog shows: "写入/更新 50 条记录"
+
+**Expected**:
+
+- ✅ Only User A's 50 materials are upserted to database
+- ✅ Other users' 900 materials are **NOT touched**
+- ✅ No materials are deleted (since other users' items aren't processed)
+
+### Scenario 3: Admin Behavior Unchanged
+
+**Setup**:
+
+- Admin logs in
+- All 1000 materials visible
+- All filtered by selected managers
+
+**Actions**:
+
+1. Admin clicks "取消" → all visible items unchecked
+2. Admin clicks "确认删除" → processes all filtered items
+
+**Expected**:
+
+- ✅ Admin behavior unchanged (can manage all data)
+- ✅ Admin can still filter by managers and process filtered results
+

+# ERP 登录调试工具使用说明
+
+## 目的
+
+用于人工调试 ERP 登录流程，定位主界面特征元素，以便优化登录成功的判定逻辑。
+
+## 前置准备
+
+### 1. 配置 ERP 登录信息
+
+编辑 `src/main/tools/erp-login-debug.ts` 文件，修改以下配置：
+
+```typescript
+const ERP_CONFIG = {
+  url: 'https://your-erp-server.com', // ← 修改为你的 ERP 地址
+  username: 'your_username', // ← 修改为你的用户名
+  password: 'your_password' // ← 修改为你的密码
+}
+```
+
+### 2. 确保 tsx 已安装
+
+如果运行时报错提示找不到 `tsx`，请安装：
+
+```bash
+npm install -g tsx
+# 或作为项目依赖
+npm install --save-dev tsx
+```
+
+## 使用方法
+
+### 方式一：使用 npm 脚本（推荐）
+
+```bash
+npm run debug:erp-login
+```
+
+### 方式二：直接运行
+
+```bash
+npx tsx src/main/tools/erp-login-debug.ts
+```
+
+## 调试流程
+
+### 步骤 1：启动脚本
+
+运行命令后，脚本会显示配置信息并等待你确认：
+
+```
+============================================================
+ERP 登录调试工具
+============================================================
+目标 URL: https://your-erp-server.com
+用户名：your_username
+密码： ***
+============================================================
+
+操作步骤：
+1. 浏览器将自动打开并尝试登录
+2. 如果登录失败，请检查配置或手动重试
+3. 登录成功后，会自动暂停并打开开发者工具
+4. 使用元素选择器定位主界面特征元素
+5. 记录元素选择器，按 Ctrl+C 退出脚本
+
+按 Enter 键开始...
+```
+
+### 步骤 2：自动登录
+
+脚本会自动执行：
+
+- 打开浏览器
+- 导航到登录页面
+- 输入用户名和密码
+- 点击登录按钮
+- 处理强制登录确认对话框（如果有）
+
+### 步骤 3：人工元素定位
+
+登录成功后，脚本会暂停并显示：
+
+```
+============================================================
+✓ 登录成功！
+============================================================
+
+现在进入调试模式，请进行以下操作：
+
+1. 按 F12 打开浏览器开发者工具
+2. 使用元素选择器 (Ctrl+Shift+C) 点击主界面特征元素
+3. 在 Elements 面板中右键元素 → Copy → Copy selector
+4. 或者使用 Playwright Inspector:
+   - 在控制台输入：await page.pause()
+   - 使用 Inspector 的元素选择工具
+
+建议定位的特征元素：
+- 主界面顶部导航栏
+- 侧边菜单栏
+- 主内容区域的唯一标识
+- 用户信息显示区域
+- 任何登录后独有的界面元素
+
+============================================================
+```
+
+### 步骤 4：记录元素选择器
+
+在开发者工具中：
+
+1. **使用元素选择器** (Ctrl+Shift+C) 点击界面元素
+2. **在 Elements 面板** 查看元素 HTML
+3. **右键元素** → Copy → 选择以下之一：
+   - `Copy selector` - CSS 选择器
+   - `Copy XPath` - XPath 路径
+   - `Copy JS path` - JavaScript 路径
+
+### 步骤 5：更新 locators.ts
+
+将找到的元素选择器添加到 `src/main/services/erp/locators.ts`：
+
+```typescript
+export const ERP_LOCATORS = {
+  // ... 现有配置 ...
+
+  // 新增：主界面特征元素（用于登录成功判定）
+  mainPage: {
+    topNavigationBar: '#top-nav', // 顶部导航栏
+    sideMenu: '.side-menu', // 侧边菜单
+    userProfile: '.user-profile', // 用户信息
+    welcomeMessage: 'internal:has-text="欢迎"' // 欢迎消息
+  }
+}
+```
+
+### 步骤 6：退出脚本
+
+按 `Ctrl+C` 终止脚本，浏览器会在 5 秒后自动关闭。
+
+## Playwright Inspector 使用技巧
+
+### 开启 Inspector
+
+在脚本暂停时，在浏览器控制台输入：
+
+```javascript
+await page.pause()
+```
+
+会打开 Playwright Inspector，提供：
+
+- 元素选择器
+- 实时 locator 测试
+- 代码生成
+
+### 测试 Locator
+
+在 Inspector 控制台测试 locator 是否有效：
+
+```javascript
+// 测试 CSS 选择器
+await page.locator('#top-nav').count()
+
+// 测试 role-based 选择器
+await page.getByRole('navigation').count()
+
+// 测试文本选择器
+await page.getByText('欢迎').count()
+```
+
+如果返回数量 > 0，说明选择器有效。
+
+## 推荐的特征元素
+
+选择登录成功判定元素时，优先选择：
+
+1. **唯一性** - 只在登录后出现
+2. **稳定性** - 不易随版本变更
+3. **易定位** - 有明确的 id、class 或文本
+
+### 推荐元素示例
+
+| 元素类型     | 选择器示例              | 说明                   |
+| ------------ | ----------------------- | ---------------------- |
+| 顶部导航栏   | `#top-nav`              | 登录后才会显示的主导航 |
+| 用户菜单     | `.user-menu`            | 显示当前用户名的菜单   |
+| 欢迎消息     | `text=欢迎`             | 包含用户名的欢迎语     |
+| 工作台标题   | `h1:has-text("工作台")` | 主界面标题             |
+| 功能模块网格 | `.module-grid`          | 功能模块入口区域       |
+
+## 常见问题
+
+### Q: 登录失败，提示找不到元素
+
+**A**: 检查以下几点：
+
+1. ERP URL 是否正确
+2. 用户名密码是否正确
+3. 网络连接是否正常
+4. ERP 系统是否可访问
+5. 是否需要验证码（如果 ERP 有验证码，需要手动输入）
+
+### Q: 登录后没有暂停
+
+**A**: 检查控制台输出，可能登录流程中抛出了异常。查看错误信息并修复。
+
+### Q: 如何调试特定页面？
+
+**A**: 修改脚本中的登录后逻辑，导航到特定页面：
+
+```typescript
+// 登录后导航到特定页面
+await page.goto(`${ERP_CONFIG.url}/yonbip/sc`)
+await page.waitForTimeout(3000)
+```
+
+### Q: 如何保存调试会话？
+
+**A**: Playwright 支持录制 trace：
+
+```typescript
+await context.tracing.start({ screenshots: true, snapshots: true })
+// ... 操作 ...
+await context.tracing.stop({ path: 'trace.zip' })
+```
+
+然后使用 `npx playwright show-trace trace.zip` 查看。
+
+## 下一步
+
+找到稳定的主界面元素后，修改以下文件优化登录判定：
+
+1. **更新 locators.ts** - 添加主界面元素定位器
+2. **修改 erp-auth.ts** - 在登录成功后等待主界面元素
+3. **更新测试** - 验证新的登录判定逻辑

+将找到的元素添加到 `src/main/services/erp/locators.ts`：
+
+```typescript
+export const ERP_LOCATORS = {
+  // ... 现有配置 ...
+
+  // 新增：主界面特征元素
+  mainPage: {
+    // 在此添加找到的元素
+    topNav: '#top-nav',
+    userMenu: '.user-menu'
+  }
+}
+```
+
+## 脚本功能
+
+### 自动执行
+
+- ✅ 启动浏览器（可见窗口，非无头模式）
+- ✅ 导航到登录页面
+- ✅ 输入用户名和密码
+- ✅ 点击登录按钮
+- ✅ 处理强制登录确认对话框
+
+### 调试支持
+
+- ✅ 登录成功后自动暂停
+- ✅ 保持浏览器打开
+- ✅ 支持 F12 开发者工具
+- ✅ 支持 Playwright Inspector
+
+### 安全特性
+
+- ✅ 密码显示为星号
+- ✅ 需要按 Enter 确认后才开始
+- ✅ 退出前 5 秒缓冲时间
+
+## 常用命令
+
+```bash
+# 运行调试脚本
+npm run debug:erp-login
+
+# 或使用 npx 直接运行
+npx tsx src/main/tools/erp-login-debug.ts
+
+# 查看帮助
+npx tsx --help
+```
+
+## 调试技巧
+
+### 测试 Locator 有效性
+
+在浏览器控制台（登录后暂停时）：
+
+```javascript
+// 测试 CSS 选择器
+await page.locator('#top-nav').count()
+
+// 测试文本选择器
+await page.getByText('欢迎').isVisible()
+
+// 测试 role 选择器
+await page.getByRole('navigation').count()
+```
+
+返回值 > 0 或 true 表示选择器有效。
+
+### 查看元素详细信息
+
+```javascript
+// 获取元素 HTML
+const element = await page.$('#top-nav')
+console.log(await element.innerHTML())
+
+// 获取元素属性
+console.log(await element.getAttributes())
+```
+
+### 截图保存
+
+```javascript
+// 全屏截图
+await page.screenshot({ path: 'login-success.png' })
+
+// 元素截图
+const element = await page.$('#top-nav')
+await element.screenshot({ path: 'top-nav.png' })
+```
+
+## 推荐的特征元素
+
+选择登录成功判定元素的标准：
+
+| 标准       | 说明           | 示例                |
+| ---------- | -------------- | ------------------- |
+| **唯一性** | 只在登录后出现 | 用户菜单、工作台    |
+| **稳定性** | 不易随版本变更 | ID 选择器优于 class |
+| **易定位** | 有明确的标识   | 有 id、独特文本     |
+
+### 推荐元素类型
+
+1. **顶部导航栏** - `#top-nav`, `.navbar`
+2. **用户信息区域** - `.user-info`, `.user-menu`
+3. **欢迎消息** - 包含用户名的文本
+4. **功能模块入口** - 主界面的模块网格
+5. **侧边菜单栏** - `.sidebar`, `.menu`
+
+## 故障排查
+
+### 问题：脚本启动后立即退出
+
+**原因**: tsx 未安装
+
+**解决**:
+
+```bash
+npm install
+```
+
+### 问题：找不到用户名/密码输入框
+
+**原因**:
+
+1. ERP URL 不正确
+2. 页面结构已变更
+3. 登录页面加载超时
+
+**解决**:
+
+1. 检查 ERP_CONFIG.url 是否正确
+2. 手动打开 URL 确认页面结构
+3. 增加 timeout 值（第 25 行）
+
+### 问题：登录后没有暂停
+
+**原因**: 登录流程抛出异常
+
+**解决**: 查看控制台错误信息，检查：
+
+- 网络连接
+- ERP 系统可用性
+- 用户名密码正确性
+
+### 问题：无法定位元素
+
+**原因**:
+
+1. 元素在 iframe 中
+2. 元素动态加载
+3. 选择器不正确
+
+**解决**:
+
+1. 检查元素是否在嵌套 iframe 中
+2. 增加等待时间 `await page.waitForTimeout(2000)`
+3. 使用更具体的选择器
+
+## 下一步
+
+找到稳定的主界面元素后：
+
+1. **更新 locators.ts**
+   - 添加 `mainPage` 配置节
+   - 定义登录成功判定元素
+
+2. **修改 erp-auth.ts**
+   - 在 `login()` 方法末尾
+   - 等待主界面元素出现
+   - 作为登录成功的最终判定
+
+3. **验证修改**
+   - 重新运行调试脚本
+   - 确认新的判定逻辑有效
+   - 更新相关文档

+# ERPAuto 优化执行计划文档
+
+基于《ERPAuto 优化建议与规范指南》，本文档规划了具体的分阶段重构与优化执行步骤。每个阶段遵循“渐进式重构”原则，保证在优化期间项目依然可运行、可测试。
+
+## 阶段一：基础设施建设 (Error & Logging)
+
+在进行大规模业务逻辑重构前，首先建立坚实的基础设施，以便后续问题排查与数据追踪。
+
+1. **引入并配置统一日志库**
+   - **目标**: 替换分散的 `console.log`。
+   - **执行**:
+     - 安装 `winston` (针对 Node.js 主进程)。
+     - 在 `src/main/services/logger` 创建单例日志记录器。
+     - 配置双通道输出：Console (Dev 环境) 与 File (生产环境按天切割，如 `%AppData%/ERPAuto/logs/app-%DATE%.log`)。
+2. **定义全局错误类型与 IPC 拦截器**
+   - **目标**: 规范前后端错误抛出与展示体系。
+   - **执行**:
+     - 在 `src/main/types/errors.ts` 定义 `BaseError`, `ErpConnectionError`, `DatabaseQueryError`。
+     - 在 `src/main/ipc/index.ts` 中封装高阶函数 `withErrorHandling`。所有 IPC Handler 统一用此高阶函数包裹，将捕获的错误统一转为 `{ success: false, error: string, code: string }` 结构。
+
+## 阶段二：数据层抽象与 ORM 改造
+
+彻底解决 SQL 语句散落和不同数据库适配成本高的问题。
+
+1. **选型并引入 ORM**
+   - **目标**: 弃用原生 SQL 拼接。
+   - **执行**:
+     - 引入 `Prisma` 或 `TypeORM`。结合当前多数据源 (MySQL + SQL Server) 需求，推荐 `TypeORM` 因为其在运行时切换数据源更为灵活。
+2. **创建 Repository 抽象**
+   - **目标**: 隔离数据库实现细节。
+   - **执行**:
+     - 建立 `src/main/services/database/repositories` 目录。
+     - 为业务实体 (如 Users, ExtractedPlans 等) 编写 Repository 类接口。
+     - 将原有 `mysql2` 和 `mssql` 的调用逐步迁移至 Repository 中。
+3. **Zod 运行时校验**
+   - **目标**: 保护 IPC 边界免受恶意/格式错误的 payload 影响。
+   - **执行**:
+     - 安装 `zod`。
+     - 对所有的 IPC Handler 的入参（如 `ExtractorInput`, `LoginRequest`）添加 `zod` Schema 校验。
+
+## 阶段三：React 渲染层规范化
+
+提高前端代码复用率，解耦视图与逻辑。
+
+1. **提取 IPC Hooks**
+   - **目标**: 清理组件中的大段异步调用。
+   - **执行**:
+     - 在 `src/renderer/src/hooks` 创建 `useExtractor.ts`, `useCleaner.ts`。
+     - 使用 React 的 `useState` 包装 `window.api` 调用，返回 `{ loading, data, error, execute }`。
+2. **状态管理引入 (Zustand)**
+   - **目标**: 解决跨组件状态共享 (如全局报错信息、用户认证状态)。
+   - **执行**:
+     - 安装 `zustand`。
+     - 创建 `useUserStore` 和 `useAppStore`。
+3. **UI 组件库/公共样式提取**
+   - **目标**: 统一 Tailwind 设计语言。
+   - **执行**:
+     - 将高频使用的 Button, Input, Modal 抽取到 `src/renderer/src/components/ui/`。
+
+## 阶段四：自动化服务解耦 (Domain Logic)
+
+将基于 Playwright 的具体执行细节与业务调度逻辑分离。
+
+1. **重构 ERP 自动化服务 (`cleaner.ts` / `extractor.ts`)**
+   - **目标**: 遵循单一职责原则。
+   - **执行**:
+     - 抽象出 `ErpBrowserManager` (负责浏览器启动与资源回收)。
+     - 抽象出 `ErpAuthService` (专职处理登录和 Session)。
+     - `extractor.ts` 将只负责调度：调用 Browser -> Auth -> Navigate -> Download -> Excel Parse。
+2. **加强 TypeScript 严格模式**
+   - **目标**: 提升代码健壮性。
+   - **执行**:
+     - 开启 `tsconfig.json` 中的 `"strict": true` 和 `"noImplicitAny": true`。
+     - 全局清理并替换现存的 `any` 为具体的 Type 或 `unknown` 并添加类型保护。
+
+## 阶段五：测试覆盖率补充
+
+确保核心流程不被破坏。
+
+1. **补充关键服务的单元测试**
+   - **目标**: 防止复杂转换逻辑衰退。
+   - **执行**:
+     - 使用 `Vitest` 测试所有的 Repository (使用内存数据库/Mock) 和工具函数 (如 ExcelParser)。
+2. **核心业务 E2E 测试**
+   - **目标**: 确保 IPC 及 Electron 整体运行顺畅。
+   - **执行**:
+     - 使用 Playwright 针对 Electron 的测试框架 (`@playwright/test` 的 electron 插件) 编写主流程测试：登录 -> 点击提取 -> 验证本地结果文件生成。
+
+## 执行建议与回顾
+
+- 每个阶段应作为一个单独的 Git 分支 (Feature Branch) 开发。
+- 完成一个阶段后，必须全量运行既有的测试套件并通过 `npm run typecheck`。
+- 本文档可作为每次 PR Review 的检查清单使用。

+# 配置保存优化设计文档
+
+**日期：** 2026-03-03
+**分支：** fix/settings-partial-save
+**状态：** 设计阶段
+
+---
+
+## 问题描述
+
+当前设置界面只能配置 3 个字段（ERP URL、用户名、密码），但保存后会意外覆盖 `.env` 文件中的其他配置项（如 `DB_TYPE`、`VALIDATION_DATA_SOURCE` 等），导致这些字段被重置为默认值或丢失。
+
+### 根本原因
+
+在 `config-manager.ts:437-483` 中，`saveAllSettings()` 方法无条件覆盖所有配置类别。当 UI 只发送部分字段时，未包含的字段会被设置为 `undefined` 或默认值，导致原有配置丢失。
+
+**数据流问题：**
+
+```
+SettingsPage (只修改 ERP URL)
+    ↓ 发送完整的 settings 对象
+ConfigManager.saveAllSettings()
+    ↓ 覆盖所有字段到缓存
+.env 文件被完全重写（丢失未被 UI 包含的字段）
+```
+
+---
+
+## 解决方案
+
+采用 **方案 A（深度合并）+ 方案 C（字段白名单）** 的组合策略：
+
+### 核心策略
+
+1. **部分更新**：只更新传入的字段，保留其他字段不变
+2. **白名单验证**：只允许 UI 支持的字段被修改
+3. **备份机制**：保存前备份，失败可回滚
+4. **安全日志**：记录所有配置变更操作
+
+---
+
+## 架构设计
+

+
+```
+┌─────────────────┐

+
+---
+
+## 核心实现
+
+### 1. 深度合并工具函数
+
+```typescript
+/**
+ * 深度合并两个对象，只更新 target 中存在的字段
+ * 保留 source 中 target 没有的字段
+ */
+function deepMerge<T>(source: T, target: Partial<T>): T {
+  const result = { ...source }
+
+  for (const key in target) {
+    if (key in target) {
+      const targetValue = target[key]
+      const sourceValue = result[key]
+
+      if (isObject(targetValue) && isObject(sourceValue)) {
+        result[key] = deepMerge(sourceValue, targetValue)
+      } else if (targetValue !== undefined) {
+        result[key] = targetValue as T[Extract<keyof T, string>]
+      }
+    }
+  }
+
+  return result
+}
+
+function isObject(value: unknown): value is Record<string, unknown> {
+  return typeof value === 'object' && value !== null && !Array.isArray(value)
+}
+```
+
+### 2. 字段白名单验证
+
+```typescript
+/**
+ * 定义 UI 可编辑的字段路径
+ * 使用点号表示法：'section.field'
+ */
+const UI_EDITABLE_FIELDS: string[] = [
+  'erp.url',
+  'erp.username',
+  'erp.password'
+  // 未来扩展：
+  // 'database.dbType',
+  // 'paths.dataDir',
+  // ...
+]
+
+/**
+ * 验证配置更新是否只包含允许的字段
+ */
+function validateEditableFields(settings: Partial<SettingsData>): {
+  valid: boolean
+  invalidFields: string[]
+} {
+  const invalidFields: string[] = []
+
+  for (const [section, values] of Object.entries(settings)) {
+    if (values && typeof values === 'object') {
+      for (const field of Object.keys(values)) {
+        const fieldPath = `${section}.${field}`
+        if (!UI_EDITABLE_FIELDS.includes(fieldPath)) {
+          invalidFields.push(fieldPath)
+        }
+      }
+    }
+  }
+
+  return {
+    valid: invalidFields.length === 0,
+    invalidFields
+  }
+}
+```
+
+### 3. 部分保存方法
+
+```typescript
+/**
+ * 保存部分配置（只更新传入的字段）
+ */
+public async savePartialSettings(
+  settings: Partial<SettingsData>
+): Promise<{ success: boolean; error?: string }> {
+  try {
+    // 步骤 1: 验证字段白名单
+    const validation = validateEditableFields(settings)
+    if (!validation.valid) {
+      log.warn('Attempted to save non-editable fields', {
+        invalidFields: validation.invalidFields
+      })
+      return {
+        success: false,
+        error: `包含不允许修改的字段：${validation.invalidFields.join(', ')}`
+      }
+    }
+
+    // 步骤 2: 读取当前配置
+    const currentSettings = this.getAllSettings()
+
+    // 步骤 3: 深度合并
+    const mergedSettings = deepMerge(currentSettings, settings)
+
+    // 步骤 4: 备份并保存
+    const backupSuccess = await this.backupEnvFile()
+    if (!backupSuccess) {
+      log.warn('Failed to backup .env file, proceeding with caution')
+    }
+
+    const saveSuccess = await this.saveAllSettings(mergedSettings)
+
+    if (!saveSuccess) {
+      // 保存失败，尝试恢复备份
+      await this.restoreBackup()
+      return {
+        success: false,
+        error: '保存配置失败，已恢复原配置'
+      }
+    }
+
+    log.info('Settings saved successfully', {
+      updatedFields: Object.keys(settings)
+    })
+
+    return { success: true }
+  } catch (error) {
+    const message = error instanceof Error ? error.message : 'Unknown error'
+    log.error('Error in savePartialSettings', { error: message })
+    await this.restoreBackup()
+    return {
+      success: false,
+      error: `保存配置时发生错误：${message}`
+    }
+  }
+}
+```
+
+### 4. 备份与恢复机制
+
+```typescript
+private backupPath: string
+
+constructor() {
+  // ...
+  this.backupPath = path.resolve(__dirname, '../../.env.backup')
+}
+
+/**
+ * 备份当前 .env 文件
+ */
+private async backupEnvFile(): Promise<boolean> {
+  try {
+    if (fs.existsSync(this.envPath)) {
+      fs.copyFileSync(this.envPath, this.backupPath)
+      log.debug('Backup created', { path: this.backupPath })
+      return true
+    }
+    return false
+  } catch (error) {
+    log.error('Failed to backup .env file', { error })
+    return false
+  }
+}
+
+/**
+ * 从备份恢复 .env 文件
+ */
+private async restoreBackup(): Promise<boolean> {
+  try {
+    if (fs.existsSync(this.backupPath)) {
+      fs.copyFileSync(this.backupPath, this.envPath)
+      await this.loadEnvFile() // 重新加载到缓存
+      log.info('Restored from backup')
+      return true
+    }
+    return false
+  } catch (error) {
+    log.error('Failed to restore backup', { error })
+    return false
+  }
+}
+```
+
+---
+
+## IPC 调用链路调整
+
+### settings-handler.ts
+
+```typescript
+ipcMain.handle(
+  'settings:saveSettings',
+  async (_event, settings: Partial<SettingsData>): Promise<SaveSettingsResult> => {
+    try {
+      log.info('Saving settings', {
+        sections: Object.keys(settings)
+      })
+
+      // 使用新的部分保存方法
+      const result = await configManager.savePartialSettings(settings)
+
+      if (result.success) {
+        log.info('Settings saved successfully')
+        return { success: true }
+      } else {
+        log.warn('Failed to save settings', {
+          error: result.error
+        })
+        return {
+          success: false,
+          error: result.error || '保存设置失败'
+        }
+      }
+    } catch (error) {
+      const message = error instanceof Error ? error.message : 'Unknown error'
+      log.error('Error saving settings', { error: message })
+      return {
+        success: false,
+        error: `保存设置失败：${message}`
+      }
+    }
+  }
+)
+```
+
+**关键改动：**
+
+- 参数类型从 `SettingsData` 改为 `Partial<SettingsData>`
+- 调用 `savePartialSettings()` 替代 `saveAllSettings()`
+
+---
+
+## 前端优化（双重保险）
+
+### SettingsPage.tsx
+
+```typescript
+const handleSaveSettings = async () => {
+  try {
+    // 只发送 UI 支持的字段（双重保险）
+    const partialSettings = {
+      erp: {
+        url: settings.erp?.url,
+        username: settings.erp?.username,
+        password: settings.erp?.password
+      }
+    }
+
+    const result = await window.electron.settings.saveSettings(partialSettings)
+
+    if (result.success) {
+      setIsModified(false)
+      showMessage('success', '设置保存成功')
+    } else {
+      showMessage('error', result.error || '保存失败')
+    }
+  } catch (error) {
+    showMessage('error', '保存设置时发生错误')
+  }
+}
+```
+
+---
+
+## 测试策略
+
+### 单元测试场景
+
+```typescript
+describe('ConfigManager.savePartialSettings', () => {
+  it('应该只更新指定的字段，保留其他字段', async () => {
+    const initial = {
+      erp: { url: 'http://old.com', username: 'user1' },
+      database: { dbType: 'mysql' }
+    }
+
+    const update = {
+      erp: { url: 'http://new.com' }
+    }
+
+    await configManager.savePartialSettings(update)
+    const result = configManager.getAllSettings()
+
+    expect(result.erp.url).toBe('http://new.com')
+    expect(result.erp.username).toBe('user1') // 保留
+    expect(result.database.dbType).toBe('mysql') // 保留
+  })
+
+  it('应该拒绝未授权的字段更新', async () => {
+    const invalidUpdate = {
+      database: { dbType: 'postgres' }
+    }
+
+    const result = await configManager.savePartialSettings(invalidUpdate)
+
+    expect(result.success).toBe(false)
+    expect(result.error).toContain('不允许修改')
+  })
+
+  it('保存失败时应该恢复备份', async () => {
+    jest.spyOn(fs, 'writeFileSync').mockImplementation(() => {
+      throw new Error('Disk full')
+    })
+
+    const result = await configManager.savePartialSettings({ erp: { url: 'x' } })
+
+    expect(result.success).toBe(false)
+  })
+})
+```
+
+### 手动验证步骤
+
+1. 打开 `.env`，记录所有字段值
+2. 打开设置页面，只修改 ERP URL
+3. 点击保存
+4. 检查 `.env`：只有 `ERP_URL` 改变，其他字段保持原值
+
+---
+
+## 未来扩展性
+
+### 1. 白名单配置化
+
+当设置页面需要支持更多配置时：
+
+```typescript
+const UI_EDITABLE_FIELDS: string[] = [
+  'erp.url',
+  'erp.username',
+  'erp.password',
+  'database.dbType', // 新增
+  'paths.dataDir', // 新增
+  'extraction.batchSize' // 新增
+  // ...
+]
+```
+
+### 2. 按用户角色分级
+
+```typescript
+const EDITABLE_FIELDS_BY_ROLE: Record<UserType, string[]> = {
+  Admin: ['*'],
+  User: ['erp.url', 'erp.username', 'erp.password'],
+  Guest: []
+}
+
+function validateEditableFields(settings: Partial<SettingsData>, userType: UserType) {
+  const allowed = EDITABLE_FIELDS_BY_ROLE[userType]
+  // 验证逻辑...
+}
+```
+
+### 3. 配置变更审计
+
+```typescript
+interface ConfigChange {
+  timestamp: Date
+  user: string
+  field: string
+  oldValue: string
+  newValue: string
+}
+```
+
+---
+
+## 实施计划
+
+下一步将创建详细的实施计划，包括：
+
+1. 在 ConfigManager 中添加深度合并和验证函数
+2. 实现 `savePartialSettings()` 方法
+3. 添加备份与恢复机制
+4. 更新 IPC handler 调用
+5. 前端优化（只发送必要字段）
+6. 编写单元测试
+7. 集成测试和手动验证
+
+---
+

+# Implementation Plan: Auto-import Extracted Data to Database
+
+## Overview
+
+Implement automatic database import after ERP data extraction completes. The merged Excel file will be read and written to the `dbo_DiscreteMaterialPlanData` table.
+
+## Requirements
+
+- **Trigger**: Automatic after extraction completes
+- **Delete Strategy**: Batch delete by `SourceNumber` before insert
+- **Batch Insert**: 1000 records per batch
+- **Field Mapping**: 28 Excel fields → database columns (skip 打印人, 打印日期, BOMVersion)
+
+## Architecture
+
+```

+## Files to Create/Modify
+
+### 1. NEW: `src/main/services/database/data-importer.ts`
+
+Main import service with:
+
+- `importFromExcel(filePath)` - Main entry point
+- `readExcelFile(filePath)` - Parse Excel using ExcelJS

+### 2. MODIFY: `src/main/services/database/discrete-material-plan-dao.ts`
+
+Add methods:
+
+- `deleteBySourceNumbers(sourceNumbers: string[])` - Batch delete
+- `batchInsert(records: MaterialPlanRecord[], batchSize: number)` - Batch insert
+
+### 3. MODIFY: `src/main/services/erp/extractor.ts`
+
+- After successful merge, call `importToDatabase(mergedFile)`
+- Add import results to `ExtractorResult`
+
+### 4. MODIFY: `src/main/types/extractor.types.ts`
+
+Add types:
+
+```typescript
+export interface ImportResult {
+  success: boolean
+  recordsImported: number
+  recordsDeleted: number
+  errors: string[]
+}
+
+export interface ExtractorResult {
+  // existing fields...
+  importResult?: ImportResult
+}
+```
+
+### 5. MODIFY: `src/renderer/src/pages/ExtractorPage.tsx`
+
+- Display import results
+- Show records deleted/imported counts
+
+## Implementation Order
+
+1. Extend `DiscreteMaterialPlanDAO` with insert/delete methods
+2. Create `DataImportService`
+3. Integrate into `ExtractorService`
+4. Update types
+5. Update UI
+
+## Testing Plan
+
+1. Unit test DAO methods
+2. Integration test with sample Excel file
+3. E2E test extraction → import flow

+# Settings Partial Save Feature
+
+## Overview
+
+The settings system now implements partial save functionality to prevent unintended overwrites of configuration values.
+
+## How It Works
+
+1. **Field Whitelist**: Only fields exposed in the UI can be modified
+2. **Deep Merge**: Updates are merged with existing config, preserving unmodified fields
+3. **Backup & Rollback**: Config is backed up before save; failures trigger automatic rollback
+
+## Editable Fields
+
+Currently editable via UI:
+
+- `erp.url` - ERP system URL
+- `erp.username` - ERP login username
+- `erp.password` - ERP login password
+
+## Adding New Editable Fields
+
+To add a new field to the UI:
+
+1. Add field to whitelist in `src/main/services/config/config-manager.ts`:
+
+```typescript
+const UI_EDITABLE_FIELDS: string[] = [
+  'erp.url',
+  'erp.username',
+  'erp.password',
+  'database.dbType' // Add new field here
+]
+```
+
+2. Add UI input in `src/renderer/src/pages/SettingsPage.tsx`
+3. Update `handleSaveSettings` to include the new field
+
+## API
+
+### savePartialSettings(settings: Partial<SettingsData>)
+
+Saves only the provided fields, preserving all existing configuration.
+
+**Returns:** `{ success: boolean, error?: string }`
+
+**Validation:**
+
+- Checks whitelist before applying changes
+- Returns error for unauthorized fields
+
+## Error Handling
+
+- **Unauthorized field**: Returns error message listing invalid fields
+- **Save failure**: Automatically restores from backup
+- **Backup failure**: Logs warning, continues with save
+
+## Backup File
+
+Location: `.env.backup` (in project root)
+
+Created before every save operation. Used for rollback on failure.

+## 架构概览 / Architecture Overview
+
+### 系统架构 / System Architecture
+
+系统设置保存功能采用典型的 Electron 三层架构模式：
+
+The system settings save functionality follows the classic Electron three-tier architecture pattern:
+
+```mermaid
+graph TB
+    subgraph "Renderer Process 渲染进程"
+        UI[SettingsPage.tsx<br/>UI Component]
+    end
+
+    subgraph "Preload Script 预加载脚本"

+    BRIDGE -->|Secure Channel| IPC
+    IPC -->|Business Logic| SERVICE
+    SERVICE -->|Write| FILE
+    FILE -->|Confirm| SERVICE
+    SERVICE -->|Result| IPC
+    IPC -->|Response| BRIDGE
+    BRIDGE -->|Promise Resolve| UI
+

+    style BRIDGE fill:#fff4e1
+    style IPC fill:#ffe1f5
+    style SERVICE fill:#e1ffe1
+    style FILE fill:#f5f5f5
+```
+
+### 核心设计模式 / Core Design Patterns
+
+1. **单向数据流**：数据从 UI → Main Process → File，响应沿相反路径返回
+2. **安全隔离**：Preload 脚本作为安全桥梁，通过 `contextBridge` 暴露受限 API
+3. **单例模式**：ConfigManager 使用单例确保配置一致性
+4. **缓存优先**：配置读取优先从内存缓存获取，写入时同步到磁盘

+### 错误场景分析 / Error Scenario Analysis
+
+| 错误场景 / Error Scenario | 触发位置 / Location | 处理方式 / Handling   | 用户反馈 / User Feedback |
+| ------------------------- | ------------------- | --------------------- | ------------------------ |
+| IPC 通信失败              | Renderer            | try-catch             | 显示"保存设置时发生错误" |
+| 权限不足                  | Main Process        | 检查 UserType         | 返回权限错误信息         |
+| 文件写入失败              | ConfigManager       | fs.writeFileSync 捕获 | 返回"保存设置失败"       |
+| 无效数据类型              | IPC Handler         | TypeScript 类型检查   | 返回验证错误             |
+| 磁盘空间不足              | File System         | OS 异常捕获           | 返回系统错误信息         |
+
+### 日志记录策略 / Logging Strategy
+
+```typescript
+// Main Process 结构化日志 / Structured Logging
+log.info('Saving settings')
+log.info('Settings saved successfully')
+log.warn('Failed to save settings')
+log.error('Error saving settings', { error: message })
+```
+
+**日志级别使用 / Log Level Usage:**
+
+- `info`: 正常操作流程
+- `warn`: 潜在问题（如保存失败但未崩溃）
+- `error`: 严重错误（如异常抛出）

+    L1[Layer 1: Context Isolation<br/>渲染进程隔离]
+    L2[Layer 2: contextBridge<br/>受限 API 暴露]

+    style L2 fill:#fff4e1
+    style L3 fill:#e1ffe1
+    style L4 fill:#ffe1f5
+```
+
+### 关键安全措施 / Key Security Measures
+
+1. **密码明文存储风险 / Password Storage Risk**
+   - ⚠️ 当前：密码以明文形式存储在 .env 文件中
+   - 🔒 建议：实现加密存储机制
+
+2. **用户权限隔离 / User Permission Isolation**
+   - ✅ 实现：基于用户类型过滤可见配置
+   - ✅ 实现：Guest 用户无法访问设置页面
+
+3. **IPC 通信安全 / IPC Communication Security**
+   - ✅ 实现：使用 `contextBridge` 而非直接暴露
+   - ✅ 实现：类型安全的 TypeScript 接口
+
+4. **文件系统访问 / File System Access**
+   - ✅ 实现：.env 文件仅主进程可访问
+   - ⚠️ 风险：文件权限取决于操作系统
+
+### 敏感数据流向 / Sensitive Data Flow
+
+```mermaid
+sequenceDiagram
+    participant User as 用户输入
+    participant UI as UI State (内存)
+    participant IPC as IPC Channel
+    participant Cache as Config Cache
+    participant File as .env File
+
+    User->>UI: password = "secret123"
+    UI->>IPC: JSON 传输 (未加密)
+    IPC->>Cache: Map.set('erp.password', 'secret123')
+    Cache->>File: 写入明文到磁盘
+
+    Note over File: ⚠️ 安全风险：<br/>密码以明文形式持久化
+```

+
+## 技术实现细节 / Technical Implementation Details
+
+### 文件位置索引 / File Location Index
+
+| 组件 / Component | 文件路径 / File Path                         | 关键行数 / Key Lines  |
+| ---------------- | -------------------------------------------- | --------------------- |
+| UI 组件          | `src/renderer/src/pages/SettingsPage.tsx`    | 61-73 (保存处理)      |
+| 预加载脚本       | `src/preload/index.ts`                       | 89-97 (API 定义)      |
+| IPC 处理器       | `src/main/ipc/settings-handler.ts`           | 83-102 (保存处理)     |
+| 配置管理器       | `src/main/services/config/config-manager.ts` | 437-483 (保存方法)    |
+| 类型定义         | `src/main/types/settings.types.ts`           | 136-171 (接口定义)    |
+| IPC 注册         | `src/main/ipc/index.ts`                      | 导入 settings-handler |
+
+### 性能特性 / Performance Characteristics
+
+1. **异步操作 / Async Operations**
+   - 所有 IPC 调用使用 `async/await` 模式
+   - 避免阻塞主进程事件循环
+
+2. **内存优化 / Memory Optimization**
+   - 使用 Map 缓存配置，减少文件读取
+   - 按需加载配置项
+
+3. **写入策略 / Write Strategy**
+   - 每次保存完整重写 .env 文件
+   - 原子写入（writeFileSync）
+
+### 依赖关系图 / Dependency Graph

+
+### 关键代码片段分析 / Key Code Snippet Analysis
+
+**1. 状态更新逻辑 / State Update Logic**
+
+```typescript
+// SettingsPage.tsx 第 50-59 行
+const updateSettings = (category: string, key: string, value: any) => {
+  setSettings((prev) => ({
+    ...prev,
+    [category]: {
+      ...(prev as any)[category],
+      [key]: value
+    }
+  }))
+  setIsModified(true) // 标记为已修改
+}
+```
+
+**设计要点 / Design Points:**
+
+- 不可变更新模式（Immutable Update Pattern）
+- 使用展开运算符保持对象引用
+- 自动启用保存按钮
+
+**2. 配置保存逻辑 / Configuration Save Logic**
+
+```typescript
+// config-manager.ts 第 437-483 行
+public async saveAllSettings(settings: SettingsData): Promise<boolean> {
+  // 批量更新缓存 (40+ 字段)
+  this.set('erp.url', settings.erp.url)
+  this.set('erp.username', settings.erp.username)
+  // ... 更多字段
+
+  // 同步写入文件
+  return this.save()
+}
+```
+
+**设计要点 / Design Points:**
+
+- 先更新内存，后写入磁盘
+- 失败时缓存保持不变
+- 返回布尔值表示成功/失败
+
+**3. .env 文件生成逻辑 / .env File Generation**
+
+```typescript
+// config-manager.ts 第 179-345 行
+public async save(): Promise<boolean> {
+  const lines: string[] = []
+
+  // 构建格式化的 .env 内容
+  lines.push('# ===========================')
+  lines.push('# ERP 系统配置')
+  lines.push('# ===========================')
+  lines.push(`ERP_URL=${this.configCache.get('erp.url') || DEFAULT_SETTINGS.erp.url}`)
+
+  const content = lines.join('\n')
+  fs.writeFileSync(this.envPath, content, 'utf-8')
+  return true
+}
+```
+
+**设计要点 / Design Points:**
+
+- 添加注释分隔符提高可读性
+- 使用默认值作为后备
+- 同步写入确保一致性

+# 物料匹配算法增强 - 用户覆盖匹配功能
+
+**实施日期**: 2026-03-03
+**功能版本**: 1.0
+**修改文件**: `src/main/ipc/validation-handler.ts`
+
+---
+
+## 功能概述
+
+为 **User 用户类型** 在物料清理界面增加了 **优先级3：用户覆盖匹配** 功能，确保 User 用户能够优先看到并管理与自己关键词匹配的物料。
+
+---
+
+## 实现的更改
+
+### 1. 获取当前用户信息
+
+**位置**: `validation-handler.ts:218-239`
+
+```typescript
+// Get current user info
+const sessionManager = (
+  await import('../services/user/session-manager')
+).SessionManager.getInstance()
+
+const userInfo = sessionManager.getUserInfo()
+if (!userInfo) {
+  return {
+    success: false,
+    error: '用户未登录',
+    stats: {
+      totalRecords: 0,
+      matchedCount: 0,
+      markedCount: 0
+    }
+  }
+}
+
+const isAdmin = userInfo.userType === 'Admin'
+const username = userInfo.username
+
+log.info('Starting validation', { mode: request.mode, user: username, isAdmin })
+```
+
+**说明**:
+
+- 在 `validation:validate` handler 开始时获取当前登录用户信息
+- 提取 `isAdmin` 和 `username` 用于后续匹配逻辑
+- 如果用户未登录，返回错误响应
+
+### 2. 新增优先级3：用户覆盖匹配
+
+**位置**: `validation-handler.ts:359-370`
+
+```typescript
+// Priority 3: User Override Match (only for non-admin users)
+// Override with current user's typeKeyword if available
+if (!isAdmin && username) {
+  const userKeywords = typeKeywords.filter((tk) => tk.managerName === username)
+  for (const userKeyword of userKeywords) {
+    if (userKeyword.materialName && materialName.includes(userKeyword.materialName)) {
+      matchedTypeKeyword = userKeyword.materialName
+      managerName = userKeyword.managerName
+      break // Force override with first match
+    }
+  }
+}
+```
+
+**匹配逻辑**:
+
+1. **适用范围**: 仅对 `isAdmin === false` 的 User 用户生效
+2. **筛选关键词**: 从 `typeKeywords` 中筛选 `managerName === username` 的记录
+3. **匹配规则**: 使用 `materialName.includes(userKeyword.materialName)` 包含关系匹配
+4. **强制覆盖**: 只要匹配成功，立即覆盖原有的 `managerName` 和 `matchedTypeKeyword`
+5. **无匹配时**: 保持优先级2的匹配结果不变
+
+---
+
+## 匹配优先级（更新后）
+
+```mermaid
+flowchart TB

+    P3 -->|未匹配| Keep[保持原结果]
+
+    Skip --> End([返回结果])
+    Override --> End
+    Keep --> End

+## 数据库配置示例
+
+### MaterialsTypeToBeDeleted 表数据
+
+| MaterialName | ManagerName | 说明                           |
+| ------------ | ----------- | ------------------------------ |
+| 螺丝         | user1       | user1 负责所有包含"螺丝"的物料 |
+| 螺母         | user2       | user2 负责所有包含"螺母"的物料 |
+| 垫圈         | user1       | user1 也负责"垫圈"类物料       |
+| 电缆         | admin       | admin 负责电缆类物料           |
+
+### 匹配结果示例
+
+| 物料名称 | 当前用户 | 原匹配 (优先级2) | 覆盖后 (优先级3)  |
+| -------- | -------- | ---------------- | ----------------- |
+| 螺丝 M6  | user1    | user2            | **user1** ✅      |
+| 螺母 M8  | user1    | user2            | user2 (无匹配)    |
+| 垫圈 φ10 | user1    | user2            | **user1** ✅      |
+| 电缆 5m  | user1    | admin            | user1 (无匹配)    |
+| 螺丝 M6  | admin    | user2            | user2 (Admin跳过) |
+

+
+## 与前端协同
+
+前端过滤器逻辑 (`CleanerPage.tsx`) 保持不变：
+
+```typescript
+const filteredResults = React.useMemo(() => {
+  let results = validationResults
+  if (!isAdmin && currentUsername) {
+    // User 只看到自己的物料 + 未分配的物料
+    results = results.filter((r) => r.managerName === currentUsername || !r.managerName)
+  }
+  return results
+}, [validationResults, isAdmin, currentUsername, managers, selectedManagers, hiddenItems])
+```
+
+**协同效果**:
+
+1. 后端匹配算法确保 User 用户的物料优先分配给自己
+2. 前端过滤器只显示属于当前用户或未分配的物料
+3. Admin 用户可以看到所有物料并切换查看不同负责人
+
+---
+
+## 代码审查检查点
+
+- ✅ User 信息获取正确使用 `SessionManager`
+- ✅ 只对 `!isAdmin` 的用户执行覆盖逻辑
+- ✅ 使用相同的包含匹配规则 `materialName.includes(typeKeyword.materialName)`
+- ✅ 优先级1（精确匹配）不受覆盖影响
+- ✅ 无匹配时保持原有结果
+- ✅ 日志记录包含用户信息 `{ user: username, isAdmin }`
+- ✅ 未登录时返回明确的错误信息
+
+---
+
+## 潜在改进方向
+
+1. **性能优化**: 如果 `typeKeywords` 数量很大，可以预先构建 `Map<username, typeKeyword[]>` 索引
+2. **日志增强**: 添加覆盖匹配的统计信息（覆盖了多少条记录）
+3. **配置开关**: 允许 Admin 用户通过配置启用/禁用覆盖功能
+4. **UI 反馈**: 在前端显示哪些物料是通过覆盖匹配分配的
+
+---

+-- Script: Fix MaterialsTypeToBeDeleted Table - Add AUTO_INCREMENT to ID
+-- Description: Modify the ID column to be AUTO_INCREMENT while preserving data
+-- Database: MySQL
+-- ============================================================================
+
+-- Step 1: Check current table structure
+SELECT
+    COLUMN_NAME,
+    COLUMN_TYPE,
+    IS_NULLABLE,
+    COLUMN_KEY,
+    COLUMN_DEFAULT,
+    EXTRA
+FROM
+    INFORMATION_SCHEMA.COLUMNS
+WHERE
+    TABLE_NAME = 'dbo_MaterialsTypeToBeDeleted'
+    AND TABLE_SCHEMA = DATABASE()
+ORDER BY
+    ORDINAL_POSITION;
+
+-- Step 2: View current data before modification
+SELECT COUNT(*) AS total_records FROM dbo_MaterialsTypeToBeDeleted;
+SELECT * FROM dbo_MaterialsTypeToBeDeleted LIMIT 10;
+
+-- Step 3: Check if ID is already AUTO_INCREMENT
+SELECT
+    COLUMN_NAME,
+    EXTRA
+FROM
+    INFORMATION_SCHEMA.COLUMNS
+WHERE
+    TABLE_NAME = 'dbo_MaterialsTypeToBeDeleted'
+    AND TABLE_SCHEMA = DATABASE()
+    AND COLUMN_NAME = 'ID';
+
+-- ============================================================================
+-- Step 4: Modify the ID column to AUTO_INCREMENT
+-- Note: This assumes ID is already the PRIMARY KEY
+-- If not, you may need to add PRIMARY KEY constraint first
+-- ============================================================================
+
+-- Option A: If ID is already PRIMARY KEY (most likely case)
+ALTER TABLE dbo_MaterialsTypeToBeDeleted
+MODIFY COLUMN ID INT NOT NULL AUTO_INCREMENT;
+
+-- Option B: If ID is NOT PRIMARY KEY (uncomment if needed)
+-- First check if there's an existing primary key
+-- SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS
+-- WHERE TABLE_NAME = 'dbo_MaterialsTypeToBeDeleted'
+-- AND TABLE_SCHEMA = DATABASE() AND COLUMN_KEY = 'PRI';
+--
+-- If no primary key exists:
+-- ALTER TABLE dbo_MaterialsTypeToBeDeleted
+-- MODIFY COLUMN ID INT NOT NULL AUTO_INCREMENT PRIMARY KEY;
+
+-- Step 5: Verify the change
+SELECT
+    COLUMN_NAME,
+    COLUMN_TYPE,
+    IS_NULLABLE,
+    COLUMN_KEY,
+    EXTRA
+FROM
+    INFORMATION_SCHEMA.COLUMNS
+WHERE
+    TABLE_NAME = 'dbo_MaterialsTypeToBeDeleted'
+    AND TABLE_SCHEMA = DATABASE()
+    AND COLUMN_NAME = 'ID';
+
+-- Step 6: Verify data is still intact
+SELECT COUNT(*) AS total_records_after FROM dbo_MaterialsTypeToBeDeleted;
+
+-- ============================================================================
+-- Expected Results:
+-- After running this script, the ID column should show:
+-- EXTRA: 'auto_increment'
+--
+-- This will allow INSERT statements to omit the ID field, and MySQL will
+-- automatically generate the next sequential ID value.
