+# 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

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

+
+## 测试场景
+
+### 场景1: User 用户匹配到自己的 typeKeyword
+
+**输入**:
+- 当前用户: `user1`
+- 物料名称: `螺丝 M6`
+- MaterialsTypeToBeDeleted: `{ materialName: "螺丝", managerName: "user1" }`
+
+**预期输出**:
+```json
+{
+  "materialName": "螺丝 M6",
+  "managerName": "user1",
+  "matchedTypeKeyword": "螺丝",
+  "isMarkedForDeletion": false
+}
+```
+
+### 场景2: User 用户覆盖其他用户的匹配
+
+**输入**:
+- 当前用户: `user1`
+- 物料名称: `螺丝 M6`
+- MaterialsTypeToBeDeleted:
+  - `{ materialName: "螺丝", managerName: "user2" }`
+  - `{ materialName: "螺丝", managerName: "user1" }`
+
+**优先级2结果**: `managerName = "user2"`
+**优先级3结果**: `managerName = "user1"` ✅ 强制覆盖
+
+### 场景3: User 用户无匹配关键词
+
+**输入**:
+- 当前用户: `user1`
+- 物料名称: `螺丝 M6`
+- MaterialsTypeToBeDeleted:
+  - `{ materialName: "螺丝", managerName: "user2" }`
+
+**预期输出**:
+```json
+{
+  "materialName": "螺丝 M6",
+  "managerName": "user2",
+  "matchedTypeKeyword": "螺丝",
+  "isMarkedForDeletion": false
+}
+```
+**说明**: 保持优先级2的匹配结果
+
+### 场景4: Admin 用户不执行覆盖
+
+**输入**:
+- 当前用户: `admin` (isAdmin=true)
+- 物料名称: `螺丝 M6`
+- MaterialsTypeToBeDeleted:
+  - `{ materialName: "螺丝", managerName: "user1" }`
+  - `{ materialName: "螺丝", managerName: "admin" }`
+
+**预期输出**:
+```json
+{
+  "materialName": "螺丝 M6",
+  "managerName": "user1",
+  "matchedTypeKeyword": "螺丝",
+  "isMarkedForDeletion": false
+}
+```
+**说明**: Admin 不执行优先级3，保持原有匹配行为
+
+### 场景5: 优先级1匹配不受影响
+
+**输入**:
+- 当前用户: `user1`
+- 物料代码: `MAT001`
+- MaterialsToBeDeleted: `{ materialCode: "MAT001", managerName: "user2" }`
+
+**预期输出**:
+```json
+{
+  "materialCode": "MAT001",
+  "managerName": "user2",
+  "isMarkedForDeletion": true,
+  "matchedTypeKeyword": undefined
+}
+```
+**说明**: 优先级1的精确匹配不受覆盖影响
+
+---
+
+## 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
