+## 4. 测试类别实施指南
+
+### 4.1 单元测试
+
+**适用范围：**
+
+- 服务类（Service）的业务逻辑
+- 工具函数（Utility Functions）
+- 数据处理函数
+- 类型转换函数
+
+**Mock 策略：**
+
+```typescript
+// 使用现有 Mock 库
+import {
+  createMockLogger,
+  createMockConfigManager,
+  createMockErpAuthService,
+  createMockDatabaseService,
+  createMockDataSource,
+  createMockRepository
+} from '@/tests/mocks'
+
+// 示例：ERP Auth 测试
+describe('ErpAuthService', () => {
+  const mockConfig = { url: 'https://test.com', username: 'test', password: 'test' }
+  const mockPage = createMockPage() // 来自 mocks/index.ts
+
+  it('should login successfully', async () => {
+    mockPage.goto.mockResolvedValue(undefined)
+    mockPage.waitForSelector.mockResolvedValue(undefined)
+
+    const authService = new ErpAuthService(mockConfig)
+    // 注入 mock (需要构造函数支持或使用 vi.mock)
+    const session = await authService.login()
+
+    expect(session.isLoggedIn).toBe(true)
+  })
+})
+```
+
+**测试覆盖重点：**
+
+1. **正常路径：** 主要业务流程成功执行
+2. **异常路径：** 错误处理、回滚、重试
+3. **边界条件：** 空输入、极大值、极小值
+4. **分支覆盖：** if/else、switch/case 所有分支
+
+---
+
+### 4.2 集成测试
+
+**适用范围：**
+
+- 多服务协作场景
+- 数据库事务边界
+- 文件系统交互
+- 外部服务调用（需 Stub）
+
+**测试模式：**
+
+```typescript
+import { describe, it, expect, beforeEach, afterEach } from 'vitest'
+import { DatabaseService } from '@/main/services/database'
+import { ConfigManager } from '@/main/services/config'
+
+describe('Database + Config Integration', () => {
+  let db: DatabaseService
+  let configManager: ConfigManager
+
+  beforeEach(async () => {
+    // 使用内存数据库或测试配置
+    configManager = ConfigManager.getInstance()
+    db = new DatabaseService(configManager)
+    await db.connect()
+  })
+
+  afterEach(async () => {
+    await db.disconnect()
+  })
+
+  it('should persist and retrieve data', async () => {
+    // 实际数据库操作
+    await db.query('INSERT INTO ...')
+    const result = await db.query('SELECT ...')
+
+    expect(result.rows).toHaveLength(1)
+  })
+})
+```

+
+---
+
+## 2. 详细质量评估
+
+### 2.1 `erp-auth.test.ts` - **A+ (95/100)**
+
+**测试对象**: `ErpAuthService` - ERP 认证服务
+
+#### 优点 ✅
+
+1. **完整的生命周期测试**
+   - 构造函数初始化验证
+   - 登录流程（成功/失败）
+   - 会话复用机制
+   - 登出/关闭处理
+
+2. **优秀的 Mock 策略**
+
+   ```typescript
+   vi.mock('playwright', () => ({
+     chromium: { launch: vi.fn() }
+   }))
+   ```
+
+   - 外部依赖完全隔离
+   - 模拟对象结构清晰
+
+3. **边界条件覆盖**
+   - `contentFrame` 返回 `null` 的异常处理
+   - 重复登录的会话复用
+   - 未登录时调用 `getSession()` 的错误处理
+
+4. **测试命名规范**
+   - 使用 `should/could` 语义
+   - 清晰表达测试意图
+
+#### 改进建议 🔧
+
+1. **缺少真实场景集成测试**
+
+   ```typescript
+   // TODO: 添加集成测试
+   it('should login with real browser (integration)', async () => {
+     // 使用真实 Playwright 浏览器测试
+   })
+   ```
+
+2. **错误消息验证不够精确**
+
+   ```typescript
+   // 当前
+   expect(() => service.getSession()).toThrow('Not logged in')
+
+   // 建议
+   expect(() => service.getSession()).toThrow('Not logged in. Call login() first.')
+   ```
+
+3. **缺少性能测试**
+   ```typescript
+   it('should complete login within 5 seconds', async () => {
+     const start = Date.now()
+     await service.login()
+     expect(Date.now() - start).toBeLessThan(5000)
+   })
+   ```
+
+#### 覆盖率评估
+
+| 方法            | 测试覆盖          | 评价 |
+| --------------- | ----------------- | ---- |
+| `constructor()` | ✓ 完全覆盖        | 优秀 |
+| `login()`       | ✓ 主要路径 + 异常 | 优秀 |
+| `getSession()`  | ✓ 覆盖            | 良好 |
+| `isActive()`    | ✓ 覆盖            | 良好 |
+| `close()`       | ✓ 覆盖            | 良好 |
+
+---
+
+### 2.2 `cleaner.test.ts` - **A (90/100)**
+
+**测试对象**: `CleanerService` - 物料清理服务
+
+#### 优点 ✅
+
+1. **纯函数测试设计优秀**
+
+   ```typescript
+   describe('shouldDeleteMaterial()', () => {
+     it('should return true when material matches all deletion criteria', () => {
+       const result = cleaner.shouldDeleteMaterial({...})
+       expect(result).toBe(true)
+     })
+   })
+   ```
+
+   - 无副作用，易于测试
+   - 输入输出明确
+
+2. **边界值测试完备**
+
+   ```typescript
+   it('should respect boundary row numbers', () => {
+     // Row 1999: can delete
+     expect(...).toBe(true)
+     // Row 2000: protected
+     expect(...).toBe(false)
+     // Row 7999: protected
+     expect(...).toBe(false)
+     // Row 8000: can delete
+     expect(...).toBe(true)
+   })
+   ```
+
+3. **辅助函数测试充分**
+   - `createBatches()`: 数组分批逻辑
+   - `runWithConcurrency()`: 并发控制验证
+   - `getMissingOrders()`: 集合差集计算
+
+4. **并发测试验证**
+   ```typescript
+   it('should limit parallelism to specified concurrency', async () => {
+     let running = 0
+     let peak = 0
+     await runWithConcurrency(items, 2, async () => {
+       running += 1
+       peak = Math.max(peak, running)
+       await new Promise((resolve) => setTimeout(resolve, 10))
+       running -= 1
+     })
+     expect(peak).toBeLessThanOrEqual(2)
+     expect(peak).toBe(2)
+   })
+   ```
+
+#### 改进建议 🔧
+
+1. **缺少 `clean()` 主方法测试**
+   - 文件顶部有 TODO 注释说明需要集成测试
+   - 建议补充：
+
+   ```typescript
+   describe('clean() - Integration', () => {
+     it('should complete full cleanup workflow', async () => {
+       // 完整流程集成测试
+     })
+   })
+   ```
+
+2. **错误场景测试不足**
+
+   ```typescript
+   // 建议添加
+   it('should handle page navigation failure', async () => {
+     // Mock 导航失败场景
+   })
+   ```
+
+3. **干运行模式测试可以更详细**
+   ```typescript
+   it('should not delete materials in dry-run mode', async () => {
+     // 验证 dryRun=true 时不执行实际删除
+   })
+   ```
+
+---
+
+### 2.3 `ErpBrowserManager.test.ts` - **A+ (95/100)**
+
+**测试对象**: `ErpBrowserManager` - 浏览器管理器
+
+#### 优点 ✅
+
+1. **状态管理测试完备**
+
+   ```typescript
+   it('should return existing browser if running', async () => {
+     const firstBrowser = await manager.launch()
+     const secondBrowser = await manager.launch()
+     expect(firstBrowser).toBe(secondBrowser)
+     expect(chromium.launch).toHaveBeenCalledTimes(1)
+   })
+   ```
+
+2. **参数化测试**
+
+   ```typescript
+   it.each([true, false])('should launch with headless=%s', async (headless) => {
+     const manager = new ErpBrowserManager({ headless })
+     await manager.launch()
+     expect(chromium.launch).toHaveBeenCalledWith(expect.objectContaining({ headless }))
+   })
+   ```
+
+3. **错误恢复测试**
+
+   ```typescript
+   it('should close browser even if context.close fails', async () => {
+     mockContext.close.mockRejectedValue(new Error('Context close error'))
+     await manager.close()
+     expect(mockBrowser.close).toHaveBeenCalled()
+   })
+   ```
+
+4. **生命周期覆盖全面**
+   - 启动 → 初始化 → 导航 → 创建上下文 → 关闭
+   - 所有公开方法都有测试
+
+#### 改进建议 🔧
+
+1. **缺少超时测试**
+
+   ```typescript
+   it('should timeout on slow page navigation', async () => {
+     mockPage.goto.mockImplementation(() => new Promise((resolve) => setTimeout(resolve, 60000)))
+     await expect(manager.navigate('http://slow.com')).rejects.toThrow('timeout')
+   })
+   ```
+
+2. **可以添加内存泄漏检测**
+   ```typescript
+   it('should release all resources after close', async () => {
+     await manager.launch()
+     await manager.close()
+     // 验证没有悬空引用
+   })
+   ```
+
+---
+
+### 2.4 `extractor-core.test.ts` - **B+ (85/100)**
+
+**测试对象**: `ExtractorCore` - 提取核心逻辑
+
+#### 优点 ✅
+
+1. **私有方法测试策略合理**
+
+   ```typescript
+   // @ts-ignore - accessing private method for testing
+   await extractorCore.waitForLoading(mockWorkFrame)
+   ```
+
+   - 使用 `@ts-ignore` 测试私有方法是可接受的
+   - 避免了为了测试而暴露内部实现
+
+2. **进度回调测试精确**
+
+   ```typescript
+   it('should calculate progress correctly', async () => {
+     await extractorCore.downloadAllBatches(input)
+     expect(progressCallback).toHaveBeenNthCalledWith(1, '处理批次 1/2', 40, {...})
+     expect(progressCallback).toHaveBeenNthCalledWith(2, '处理批次 2/2', 60, {...})
+   })
+   ```
+
+3. **错误处理验证**
+
+   ```typescript
+   it('should handle errors in batch download gracefully', async () => {
+     vi.spyOn(extractorCore as any, 'downloadBatch')
+       .mockResolvedValueOnce('/path/file1.xlsx')
+       .mockRejectedValueOnce(new Error('Network error'))
+
+     const result = await extractorCore.downloadAllBatches(input)
+     expect(result.errors).toHaveLength(1)
+   })
+   ```
+
+#### 不足 ⚠️
+
+1. **3 个测试标记为 TODO**
+
+   ```typescript
+   it.todo('TODO: needs integration test setup - should handle complete navigation flow')
+   it.todo('TODO: needs integration test setup - should handle download events correctly')
+   it.todo('TODO: needs integration test setup - should verify locator interactions')
+   ```
+
+   - **影响**: 核心功能缺少完整流程测试
+   - **建议**: 优先级 P0，尽快补充集成测试
+
+2. **Mock 过于复杂**
+   - `navigateToExtractorPage` 和 `downloadBatch` 都被 Mock
+   - 实际只测试了流程编排，未测试真实逻辑
+
+#### 改进建议 🔧
+
+**高优先级**:
+
+```typescript
+// 集成测试示例
+describe('ExtractorCore - Integration', () => {
+  it('should handle real iframe navigation', async () => {
+    // 使用真实 Playwright 浏览器
+    // 测试完整的 iframe 查找和内容帧获取
+  })
+})
+```
+
+---
+
+### 2.5 `extractor.test.ts` - **A (90/100)**
+
+**测试对象**: `ExtractorService` - 提取服务
+
+#### 优点 ✅
+
+1. **依赖注入测试**
+
+   ```typescript
+   beforeEach(() => {
+     mockExcelParserInstance = { parse: vi.fn().mockResolvedValue(undefined) }
+     mockDataImportInstance = { importFromExcel: vi.fn().mockResolvedValue({...}) }
+     mockExtractorCoreInstance = { downloadAllBatches: vi.fn().mockResolvedValue({...}) }
+   })
+   ```
+
+2. **私有方法测试合理**
+
+   ```typescript
+   // @ts-ignore - accessing private method for testing
+   const result = await service.mergeFiles(['./file1.xlsx'], ['ORD001'])
+   ```
+
+3. **错误传播测试**
+
+   ```typescript
+   it('should handle extraction errors gracefully', async () => {
+     mockExtractorCoreInstance.downloadAllBatches.mockRejectedValue(new Error('Network error'))
+     const result = await service.extract({ orderNumbers: ['ORD001'] })
+     expect(Array.isArray(result.errors)).toBe(true)
+   })
+   ```
+
+4. **性能监控集成测试**
+   ```typescript
+   it('should wrap import in trackDuration', async () => {
+     await service.importToDatabaseWithLogging('./merged.xlsx', onLog)
+     expect(trackDuration).toHaveBeenCalledWith(
+       expect.any(Function),
+       expect.objectContaining({ operationName: 'Database Import' })
+     )
+   })
+   ```
+
+#### 改进建议 🔧
+
+1. **缺少 `extract()` 主方法完整流程测试**
+   - 只有基础行为测试
+   - 建议添加完整 E2E 流程
+
+2. **Mock 重置策略可以更清晰**
+   ```typescript
+   // 建议在每个测试前明确重置所有 Mock
+   beforeEach(() => {
+     vi.clearAllMocks()
+     mockExcelParserInstance.lastOrders = [] // 显式清空
+   })
+   ```
+
+---
+
+### 2.6 `order-resolver.test.ts` - **A+ (95/100)**
+
+**测试对象**: `OrderNumberResolver` - 订单号解析器
+
+#### 优点 ✅
+
+1. **测试覆盖率最高**
+   - 26 个测试用例，覆盖所有公开方法
+   - 包含性能测试
+
+2. **类型识别测试完备**
+
+   ```typescript
+   describe('isProductionId()', () => {
+     it('should recognize valid production IDs', () => {
+       expect(resolver.isProductionId('22A1')).toBe(true)
+       expect(resolver.isProductionId('26B10617')).toBe(true)
+     })
+     it('should reject invalid formats', () => {
+       expect(resolver.isProductionId('SC70202602120085')).toBe(false)
+       expect(resolver.isProductionId('abc')).toBe(false)
+     })
+   })
+   ```
+
+3. **去重逻辑测试**
+
+   ```typescript
+   it('deduplicates identical inputs', async () => {
+     const results = await resolver.resolve(['22A1', '22A1', '22A1'])
+     expect(results).toHaveLength(1) // deduplicated
+   })
+   ```
+
+4. **性能测试**
+
+   ```typescript
+   it('performance with large order sets', async () => {
+     const largeInput = Array.from({ length: 100 }, (_, i) => `22A${i}`)
+     const startTime = Date.now()
+     const results = await resolver.resolve(largeInput)
+     const elapsed = Date.now() - startTime
+     expect(elapsed).toBeLessThan(5000)
+   })
+   ```
+
+5. **统计和报告测试**
+   - `getStats()`: 统计数据准确性
+   - `getWarnings()`: 警告消息格式化
+   - `getDeduplicationReport()`: 去重报告生成
+
+#### 改进建议 🔧
+
+1. **可以添加数据库连接失败的重试测试**
+
+   ```typescript
+   it('should retry on transient database errors', async () => {
+     // Mock 第一次失败，第二次成功
+     // 验证重试逻辑
+   })
+   ```
+
+2. **缓存策略测试可以更详细**
+   ```typescript
+   it('should cache resolved mappings', async () => {
+     // 验证相同输入不会重复查询数据库
+   })
+   ```
+
+---
+
+## 3. 共性问题与建议
+
+### 3.1 Mock 策略优化
+
+**当前做法**:
+
+```typescript
+vi.mock('playwright', () => ({
+  chromium: { launch: vi.fn() }
+}))
+```
+
+**建议改进**:
+
+```typescript
+// 使用工厂函数创建可重置的 Mock
+const createMockPlaywright = () => ({
+  chromium: {
+    launch: vi.fn().mockResolvedValue(createMockBrowser()),
+    connect: vi.fn()
+  }
+})
+
+beforeEach(() => {
+  vi.mocked(chromium.launch).mockResolvedValue(createMockBrowser())
+})
+```
+
+**好处**:
+
+- 每个测试独立的 Mock 状态
+- 避免测试间的相互影响
+- 更易维护
+
+### 3.2 测试数据工厂
+
+**当前**: 手动创建测试数据
+
+```typescript
+const config = {
+  url: 'https://test-erp.com',
+  username: 'testuser',
+  password: 'testpass',
+  headless: true
+}
+```
+
+**建议**: 使用工厂函数
+
+```typescript
+// tests/fixtures/factory.ts
+const ErpConfigFactory = {
+  create: (overrides?: Partial<ErpConfig>) => ({
+    url: 'https://test-erp.com',
+    username: 'testuser',
+    password: 'testpass',
+    headless: true,
+    ...overrides
+  })
+}
+
+// 测试中
+const config = ErpConfigFactory.create({ headless: false })
+```
+
+### 3.3 错误消息断言
+
+**当前**:
+
+```typescript
+await expect(service.login()).rejects.toThrow('Failed to access')
+```
+
+**建议**: 使用更精确的匹配
+
+```typescript
+await expect(service.login()).rejects.toThrow(
+  expect.objectContaining({
+    message: expect.stringContaining('Failed to access forwardFrame')
+  })
+)
+```
+
+### 3.4 集成测试缺失
+
+**问题**: 多个文件有 TODO 注释说明需要集成测试
+
+**建议优先级**:
+
+1. **P0**: `extractor-core.test.ts` - 3 个 TODO
+2. **P1**: `extractor.test.ts` - `extract()` 完整流程
+3. **P1**: `cleaner.test.ts` - `clean()` 完整流程
+
+**集成测试框架建议**:
+
+```typescript
+// tests/integration/erp/extractor.integration.test.ts
+import { test, expect } from '@playwright/test'
+
+test('complete extraction workflow', async () => {
+  // 使用真实浏览器
+  // 测试完整提取流程
+})
+```
+
+---
+
+## 4. 测试设计模式评估
+
+### 4.1 AAA 模式 (Arrange-Act-Assert)
+
+**评分**: **优秀** ✅
+
+所有测试都遵循 AAA 模式：
+
+```typescript
+it('should create session on successful login', async () => {
+  // Arrange
+  service = new ErpAuthService(config)
+
+  // Act
+  const session = await service.login()
+
+  // Assert
+  expect(chromium.launch).toHaveBeenCalledWith(...)
+  expect(session.isLoggedIn).toBe(true)
+})
+```
+
+### 4.2 测试独立性
+
+**评分**: **良好** ⚠️
+
+**优点**:
+
+- 每个测试使用 `beforeEach` 重置状态
+- `vi.clearAllMocks()` 调用普遍
+
+**改进点**:
+
+- 部分测试依赖前一个测试的 Mock 状态
+- 建议在每个测试中完全独立设置 Mock
+
+### 4.3 测试可读性
+
+**评分**: **优秀** ✅
+
+- 测试命名清晰：`should/could` 语义
+- 分组合理：`describe` 层次分明
+- 注释充分：关键步骤有说明
+
+### 4.4 测试可维护性
+
+**评分**: **良好** ⚠️
+
+**优点**:
+
+- 代码结构清晰
+- 重复代码较少
+
+**改进点**:
+
+- 缺少测试数据工厂
+- Mock 设置代码重复
+- 魔法数字（如 `40`, `60` 进度值）缺少常量定义

+## 5. 覆盖率分析
+
+### 5.1 方法覆盖率
+
+| 服务                  | 公开方法 | 已测试 | 覆盖率 |
+| --------------------- | -------- | ------ | ------ |
+| `ErpAuthService`      | 5        | 5      | 100%   |
+| `CleanerService`      | 7        | 4      | 57% ⚠️ |
+| `ErpBrowserManager`   | 9        | 9      | 100%   |
+| `ExtractorCore`       | 3        | 2      | 67% ⚠️ |
+| `ExtractorService`    | 5        | 4      | 80%    |
+| `OrderNumberResolver` | 10       | 10     | 100%   |
+
+### 5.2 分支覆盖率估算
+
+| 服务                  | 条件分支 | 已覆盖 | 估算覆盖率 |
+| --------------------- | -------- | ------ | ---------- |
+| `ErpAuthService`      | 8        | 7      | 87%        |
+| `CleanerService`      | 15       | 12     | 80%        |
+| `ErpBrowserManager`   | 10       | 9      | 90%        |
+| `ExtractorCore`       | 12       | 8      | 67%        |
+| `ExtractorService`    | 14       | 11     | 78%        |
+| `OrderNumberResolver` | 20       | 18     | 90%        |
+
+### 5.3 未覆盖的关键路径
+
+1. **CleanerService**
+   - `clean()` 主方法的完整流程
+   - 重试机制 (`retryFailedOrders`)
+   - 进度发布 (`publishProgress`)
+
+2. **ExtractorCore**
+   - `navigateToExtractorPage()` 完整导航逻辑
+   - `downloadBatch()` 实际下载流程
+   - iframe 交互的真实场景
+
+3. **ExtractorService**
+   - `extract()` 方法的完整编排流程
+   - 并发控制在实际场景中的表现
+
+---
+
+## 6. 性能测试评估
+
+### 6.1 现有性能测试
+
+**优秀示例**:
+
+```typescript
+it('performance with large order sets', async () => {
+  const largeInput = Array.from({ length: 100 }, (_, i) => `22A${i}`)
+  const startTime = Date.now()
+  const results = await resolver.resolve(largeInput)
+  const elapsed = Date.now() - startTime
+  expect(elapsed).toBeLessThan(5000)
+})
+```
+
+### 6.2 缺失的性能测试
+
+1. **并发性能**
+
+   ```typescript
+   it('should handle 1000 concurrent orders', async () => {
+     const orders = Array.from({ length: 1000 }, (_, i) => `ORD${i}`)
+     const start = Date.now()
+     await resolver.resolve(orders)
+     expect(Date.now() - start).toBeLessThan(10000)
+   })
+   ```
+
+2. **内存使用**
+   ```typescript
+   it('should not leak memory on repeated calls', async () => {
+     const initialMemory = process.memoryUsage().heapUsed
+     for (let i = 0; i < 100; i++) {
+       await service.extract({ orderNumbers: ['ORD001'] })
+     }
+     const finalMemory = process.memoryUsage().heapUsed
+     expect(finalMemory - initialMemory).toBeLessThan(10 * 1024 * 1024) // < 10MB
+   })
+   ```
+
+---
+
+## 7. 错误处理测试评估
+
+### 7.1 优秀实践 ✅
+
+1. **网络错误处理**
+
+   ```typescript
+   mockExtractorCoreInstance.downloadAllBatches.mockRejectedValue(new Error('Network error'))
+   ```
+
+2. **数据库连接失败**
+
+   ```typescript
+   vi.mocked(mockDbService.query).mockRejectedValue(new Error('Database connection failed'))
+   ```
+
+3. **元素未找到**
+   ```typescript
+   mockPage.locator = vi.fn().mockReturnValue({
+     contentFrame: vi.fn().mockResolvedValue(null)
+   })
+   await expect(service.login()).rejects.toThrow('Failed to access')
+   ```
+
+### 7.2 改进建议 🔧
+
+1. **添加错误类型验证**
+
+   ```typescript
+   it('should throw specific error types', async () => {
+     await expect(service.login()).rejects.toThrow(ErpAuthenticationError)
+   })
+   ```
+
+2. **错误上下文验证**
+   ```typescript
+   it('should include context in error messages', async () => {
+     try {
+       await service.login()
+     } catch (error) {
+       expect(error.context).toEqual({
+         url: 'https://test-erp.com',
+         step: 'login'
+       })
+     }
+   })
+   ```

+# 清理器角色差异流程 — Admin vs User
+
+**文档版本**: 1.1
+**创建日期**: 2026-04-06
+**面向对象**: 开发人员
+
+## 概述
+
+清理器（Cleaner）在决定"哪些物料需要被清除"时，Admin 和 User 两个角色存在系统性的差异。这些差异贯穿三个阶段：**初始化 → 校验确认 → 执行清理**。
+
+本文档使用 Mermaid 图表说明每个阶段的角色分支逻辑。
+
+---
+
+## 全局流程概览
+
+```mermaid
+flowchart TB
+    subgraph init["阶段一：页面初始化"]
+        I1([页面加载]) --> I2{角色判断}
+        I2 -->|Admin| I3["管理员列表 ← 全部负责人<br/>默认选中全部"]
+        I2 -->|User| I4["管理员列表 ← 空<br/>默认选中仅自己"]
+    end
+
+    subgraph validate["阶段二：校验 → 勾选 → 同步数据库"]
+        V1([点击校验]) --> V2["后端查询物料<br/>（不区分角色）"]
+        V2 --> V3["物料匹配算法<br/>（User 有覆盖匹配）"]
+        V3 --> V4{角色判断}
+        V4 -->|Admin| V5["显示全部物料<br/>侧边栏可按负责人筛选"]
+        V4 -->|User| V6["仅显示自己的物料<br/>+ 无负责人的物料"]
+        V5 --> V7["用户勾选/取消勾选"]
+        V6 --> V7
+        V7 --> V8{点击同步数据库}
+        V8 --> V9{角色判断}
+        V9 -->|Admin| V10["处理范围：全部校验结果"]
+        V9 -->|User| V11["处理范围：仅筛选后结果"]
+    end
+
+    subgraph execute["阶段三：执行清理（ERP 删除）"]
+        E1([点击执行清理]) --> E2["getCleanerData(selectedManagers)<br/>获取物料代码"]
+        E2 --> E3{角色判断}
+        E3 -->|Admin| E3a{selectedManagers<br/>非空?}
+        E3a -->|"是"| E4["SQL WHERE ManagerName IN (选中)<br/>从 MaterialsToBeDeleted 获取"]
+        E3a -->|"否"| E4b["从 DiscreteMaterialPlanData<br/>按 orderNumbers 获取"]
+        E3 -->|User| E5["SQL WHERE ManagerName = 用户<br/>仅获取自己的物料代码"]
+        E4 --> E6["传递给 runCleaner 执行"]
+        E4b --> E6
+        E5 --> E6
+        E6 --> E7([在 ERP 中删除物料])
+    end
+
+    init --> validate --> execute
+```
+
+---
+
+## 阶段一：页面初始化
+
+**源码位置**: `src/renderer/src/hooks/cleaner/api.ts:25-52` 与 `src/renderer/src/hooks/useCleaner.ts:98-112`
+
+```mermaid
+flowchart TB
+    Start([页面加载]) --> GetAdmin["调用 auth:isAdmin<br/>判断是否管理员"]
+    GetAdmin --> GetUser["调用 auth:getCurrentUser<br/>获取当前用户名"]
+    GetUser --> RoleCheck{isAdmin?}
+
+    RoleCheck -->|Admin| GetManagers["调用 materials:getManagers<br/>获取全部负责人列表"]
+    GetManagers --> SelectAll["selectedManagers ← 全部负责人<br/>（默认全选）"]
+    SelectAll --> RenderSidebar["渲染 CleanerSidebar<br/>显示负责人复选框"]
+
+    RoleCheck -->|User| SetSelf["selectedManagers ← {currentUsername}<br/>（仅选中自己）"]
+    SetSelf --> NoSidebar["不渲染 CleanerSidebar<br/>无侧边栏"]
+
+    RenderSidebar --> Ready([就绪])
+    NoSidebar --> Ready
+```
+
+**差异总结**:
+
+| 维度 | Admin | User |
+|------|-------|------|
+| 侧边栏 | 有 CleanerSidebar | 无 |
+| 管理员列表 | 查询全部负责人 | 不查询 |
+| 默认选中 | 所有负责人 | 仅自己 |
+
+---
+
+## 阶段二：校验 → 勾选 → 同步数据库
+
+### 2.1 物料校验（后端，不区分角色）
+
+**源码位置**: `src/main/services/validation/validation-application-service.ts`
+
+校验阶段后端查询不区分角色，Admin 和 User 拿到相同的物料数据。区别在于**匹配算法**：
+
+```mermaid
+flowchart TB
+    Start([遍历每条物料记录]) --> P1{"优先级1<br/>MaterialsToBeDeleted<br/>精确匹配 MaterialCode?"}
+
+    P1 -->|"匹配"| SetManager["managerName ← 表中记录<br/>isMarkedForDeletion = true"]
+    P1 -->|"未匹配"| P2{"优先级2<br/>MaterialsTypeToBeDeleted<br/>MaterialName 包含匹配?"}
+
+    P2 -->|"匹配"| SetType["managerName ← 类型关键词负责人<br/>matchedTypeKeyword ← 匹配项"]
+    P2 -->|"未匹配"| SetNull["managerName = null"]
+
+    SetManager --> RoleCheck{角色?}
+    SetType --> RoleCheck
+    SetNull --> RoleCheck
+
+    RoleCheck -->|"Admin"| Skip["跳过覆盖<br/>使用当前结果"]
+    RoleCheck -->|"User"| P3{"优先级3（User 覆盖）<br/>自己的类型关键词匹配?"}
+
+    P3 -->|"匹配"| Override["强制覆盖<br/>managerName ← 当前用户"]
+    P3 -->|"未匹配"| Keep["保持当前结果"]
+    Skip --> Next(["下一条物料"])
+    Override --> Next
+    Keep --> Next
+```
+
+**匹配优先级说明**:
+
+| 优先级 | 数据源 | 匹配方式 | 适用角色 |
+|--------|--------|----------|----------|
+| 1（最高） | `MaterialsToBeDeleted` | MaterialCode 精确匹配 | 全部 |
+| 2 | `MaterialsTypeToBeDeleted` | MaterialName 包含匹配 | 全部 |
+| 3（User 覆盖） | 当前用户的类型关键词 | MaterialName 包含匹配 | 仅 User |
+
+> **优先级 3 的作用**：当某个物料按优先级 2 被分配给其他负责人，但当前 User 有匹配的类型关键词时，会强制覆盖为自己的。这确保 User 不会为他人操作物料。
+
+### 2.2 前端显示过滤
+
+**源码位置**: `src/renderer/src/hooks/cleaner/helpers.ts:34-57`
+
+校验结果返回前端后，会根据角色进行显示过滤：
+
+```mermaid
+flowchart TB
+    Input([校验结果 validationResults]) --> RoleCheck{角色判断}
+
+    RoleCheck -->|Admin| FilterManagers["按侧边栏选中的负责人过滤<br/>selectedManagers.has(managerName)<br/>|| !managerName"]
+    RoleCheck -->|User| FilterSelf["仅显示自己的 + 无负责人的<br/>managerName === currentUsername<br/>|| !managerName"]
+
+    FilterManagers --> FilterHidden["排除已隐藏的物料<br/>!hiddenItems.has(materialCode)"]
+    FilterSelf --> FilterHidden
+
+    FilterHidden --> Output([filteredResults<br/>用于表格显示])
+```
+
+### 2.3 确认删除（同步数据库）
+
+**源码位置**: `src/renderer/src/hooks/useCleaner.ts:289-344`
+
+```mermaid
+flowchart TB
+    Start([点击确认删除]) --> RoleScope{角色判断}
+
+    RoleScope -->|Admin| UseAll["resultsToProcess = validationResults<br/>处理全部校验结果"]
+    RoleScope -->|User| UseFiltered["resultsToProcess = filteredResults<br/>仅处理筛选后结果"]
+
+    UseAll --> BuildPlan["buildDeletionPlan(resultsToProcess, selectedItems)"]
+    UseFiltered --> BuildPlan
+
+    BuildPlan --> Loop["遍历 resultsToProcess"]
+    Loop --> Check{物料是否勾选?}
+
+    Check -->|"已勾选"| HasManager{有负责人?}
+    Check -->|"未勾选"| ToDelete["加入 materialsToDelete<br/>从数据库移除标记"]
+
+    HasManager -->|"有"| ToUpsert["加入 materialsToUpsert<br/>写入/更新到数据库"]
+    HasManager -->|"无"| Missing["加入 missingManager<br/>阻止操作"]
+
+    ToUpsert --> Save["调用 materials:upsertBatch"]
+    ToDelete --> Del["调用 materials:delete"]
+    Missing --> Warn(["弹窗警告：缺少负责人"])
+    Save --> Done([完成])
+    Del --> Done
+```
+
+**关键代码**:
+
+```typescript
+// Admin 处理全部结果，User 只处理筛选后的结果
+const resultsToProcess = isAdmin ? validationResults : filteredResults
+```
+
+**差异总结**:
+
+| 维度 | Admin | User |
+|------|-------|------|
+| 处理范围 | `validationResults`（全部） | `filteredResults`（自己的+无负责人的） |
+| 可操作物料 | 所有负责人的物料 | 仅自己的 + 无负责人的 |
+| 能否修改他人数据 | 是 | 否 |

+
+**SQL 差异**:
