1.15.0

- Update rename notice in all 6 doc files to state that the rename from
  ERPAuto to BIPMaterialManager is currently a plan only, with no actual
  code changes implemented
- Documentation names updated for forward compatibility; all code-level
  configs, paths, and artifact names remain unchanged

+## 📝 文档命名规范
+
+### 文件名格式
+
+```
+<主题>-<子主题>-<类型>.md
+```
+
+**规则：**
+
+- 使用**小写字母**和**连字符** (`-`)
+- 不使用空格、下划线或大写字母
+- 保持简短但有描述性
+
+**示例：**
+
+```
+✅ user-override-match-feature.md
+✅ settings-partial-save.md
+✅ cleaner-validation-flow.md
+✅ test-improvement-plan.md
+
+❌ UserOverrideMatchFeature.md    # 驼峰命名
+❌ user_override_match.md         # 下划线
+❌ user override match.md         # 空格
+```
+
+### 类型后缀约定
+
+| 后缀           | 用途       | 示例                                      |
+| -------------- | ---------- | ----------------------------------------- |
+| `-guide.md`    | 指南类文档 | `erp-login-debug-guide.md`                |

+| `-report.md`   | 报告总结   | `TEST_REVIEW_REPORT.md`                   |
+| `-template.md` | 模板文件   | `cleaner-execution-report-template.md`    |
+| `-overview.md` | 概览说明   | `validation-handler-refactor-overview.md` |
+
+### Plans 路径专用命名规范
+
+`plans/` 目录使用**日期前缀**命名法，便于按时间排序和管理：
+
+```
+<YYYY-MM-DD>-<描述>-<类型>.md
+```
+
+**类型标识：**
+
+| 类型后缀     | 用途     | 内容重点                               |
+| ------------ | -------- | -------------------------------------- |
+| `-plan.md`   | 实施计划 | 任务分解、时间线、资源分配、风险评估   |
+| `-design.md` | 设计方案 | 技术架构、接口设计、数据模型、决策理由 |
+
+**示例：**
+
+```
+✅ 2026-04-13-cleaner-db-persistence-plan.md
+✅ 2026-04-13-cleaner-db-persistence-design.md
+✅ 2026-04-05-postgresql-integration-plan.md
+✅ 2026-04-05-postgresql-integration-design.md
+
+❌ cleaner-db-plan.md              # 缺少日期
+❌ 2026-4-13-cleaner-db-plan.md    # 日期格式不正确（应为 2026-04-13）
+❌ 2026-04-13-plan-cleaner-db.md   # 类型应在最后
+```
+
+**相关文件对：**
+同一个项目通常会有配对的计划和设计文档：
+
+- `2026-04-13-cleaner-db-persistence-plan.md` - 实施计划
+- `2026-04-13-cleaner-db-persistence-design.md` - 设计方案
+
+使用相同的日期和描述，便于关联查找。

+# 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

+        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
+```
+

+## 数据安全边界
+
+角色隔离在**三个层面**同时生效，形成纵深防御：

+```mermaid

+    subgraph layer1["第一层：前端过滤"]
+        L1["filterValidationResults()<br/>User 仅看到自己的物料"]
+    end
+
+    subgraph layer2["第二层：同步范围"]
+        L2["handleConfirmDeletion()<br/>User 仅同步 filteredResults"]
+    end
+
+    subgraph layer3["第三层：后端查询"]
+        L3["loadMaterialCodesForCleaner()<br/>Admin: WHERE ManagerName IN (selectedManagers)<br/>User: SQL WHERE ManagerName = user"]
+    end
+
+    L1 -->|"防止误操作"| L2
+    L2 -->|"缩小同步范围"| L3
+    L3 -->|"最终保证"| Safe([User 无法删除他人物料])
+```
+
+> **注意**：`runCleaner()` 本身不做角色过滤，它信任上游传入的 `materialCodes` 已经过角色过滤。安全性由 `getCleanerData()` 的 SQL 查询保证。

+# PostgreSQL 集成设计文档
+
+**日期:** 2026-04-05
+**状态:** 已批准
+**分支:** dev-logging
+
+## 目标
+
+将 PostgreSQL 作为第三种可选数据库类型集成到 ERPAuto 中，与现有 MySQL、SQL Server 并列。通过引入 SqlDialect 抽象层，统一管理三种数据库的 SQL 方言差异，同时重构现有 DAO 层消除散落的 `isSqlServer` 判断。
+
+## 背景
+
+- PostgreSQL 数据库已通过 SSMA 从 SQL Server 迁移完成，表结构、schema 组织、列名完全一致
+- 连接信息：`postgresql://admin:***@192.168.31.83:5432/postgres`，数据库 `CompanyDB`
+- 共 15 个 schema、151 张表，`dbo` schema 包含 ERPAuto 直接使用的表
+
+## 方案：抽象数据库方言层
+
+### 1. SqlDialect 接口
+
+新建 `src/main/types/sql-dialect.types.ts`：
+
+```typescript
+export interface SqlDialect {
+  readonly dbType: DatabaseType
+
+  // 表名引用
+  quoteTableName(schema: string, table: string): string
+
+  // 参数占位符
+  param(index: number): string
+  params(count: number): string
+
+  // SQL 函数
+  currentTimestamp(): string
+
+  // UPSERT
+  upsert(p: {
+    table: string
+    keyColumns: string[]
+    valueColumns: string[]
+    placeholderCount: number
+    startParamIndex: number
+  }): string
+
+  // 分页
+  paginate(p: { sql: string; limit: number; offset?: number; paramIndex: number }): {
+    sql: string
+    paramIndex: number
+  }
+
+  // 批量限制
+  maxBatchRows(columnsPerRow: number): number
+}
+```
+
+### 2. 三种方言实现
+
+新建 `src/main/services/database/dialects/` 目录：
+
+| 文件                    | 数据库     | param(n) | quoteTableName  | currentTimestamp    | upsert             | paginate           |
+| ----------------------- | ---------- | -------- | --------------- | ------------------- | ------------------ | ------------------ |
+| `mysql-dialect.ts`      | MySQL      | `?`      | `dbo_Table`     | `NOW()`             | `ON DUPLICATE KEY` | `LIMIT x OFFSET y` |
+| `sqlserver-dialect.ts`  | SQL Server | `@p{n}`  | `[dbo].[Table]` | `GETDATE()`         | `MERGE`            | `OFFSET/FETCH`     |
+| `postgresql-dialect.ts` | PostgreSQL | `${n+1}` | `"dbo"."Table"` | `CURRENT_TIMESTAMP` | `ON CONFLICT`      | `LIMIT x OFFSET y` |
+
+方言工厂 `dialects/index.ts`：
+
+```typescript
+export function createDialect(type: DatabaseType): SqlDialect
+```
+
+### 3. DAO 层重构
+
+每个 DAO 新增 `dialect` 成员，替代原有的 `getTableName()`、`buildPlaceholders()` 和所有 `isSqlServer` 分支：
+
+**删除：**
+
+- `getTableName()` 私有方法
+- `buildPlaceholders()` 私有方法
+- 所有 `isSqlServer` 局部变量和条件分支
+- `*_CONFIG` 中的 `TABLE_NAME_SQLSERVER` / `TABLE_NAME_MYSQL` → 合并为 `TABLE_SCHEMA` + `TABLE_NAME`
+
+**新增：**
+
+- `private dialect: SqlDialect | null = null`
+- `private getDialect(): SqlDialect`
+
+**涉及 DAO：**
+
+- `DiscreteMaterialPlanDAO` — 占位符、表名、批量大小
+- `MaterialsToBeDeletedDAO` — 占位符、表名、MERGE/ON DUPLICATE KEY → `upsert()`
+- `MaterialsTypeToBeDeletedDAO` — 同上
+- `ExtractorOperationHistoryDAO` — 占位符、表名、GETDATE()/NOW() → `currentTimestamp()`、分页 → `paginate()`
+
+### 4. PostgreSQL 服务层
+
+新建 `src/main/services/database/postgresql.ts`：
+
+- 使用 `pg` 驱动，`Pool` 连接池
+- 实现 `IDatabaseService` 接口
+- `query()` 直接传递参数数组给 `pg`
+- `transaction()` 使用 `client.query('BEGIN/COMMIT/ROLLBACK')`
+
+### 5. 工厂、配置、TypeORM
+
+**database/index.ts：** `create()` 新增 `'postgresql'` 分支，新增 `createPostgreSqlConfig()`
+
+**database.types.ts：** `DatabaseType` 扩展为 `'mysql' | 'sqlserver' | 'postgresql'`，新增 `PostgreSqlConfig`
+
+**data-source.ts：** TypeORM `type` 映射新增 `'postgres'`
+
+**config.template.yaml：** 新增 `postgresql` 配置段
+
+**package.json：** 新增 `pg` 依赖
+
+## 改动范围

+# Cleaner 数据库持久化设计
+
+## 背景
+
+Cleaner 当前使用 Markdown 文件做执行记录持久化，通过 RustFS 上传存储。存在以下问题：
+
+- 报告是非结构化文本，无法程序化查询和统计
+- 历史记录无法按用户、时间、状态筛选
+- 重试时依赖文件名去重，覆盖了首次执行的崩溃信息
+- 前端需要通过 RustFS 下载报告再解析展示，链路长且脆弱
+
+Extractor 已有成熟的数据库持久化模式（`ExtractorOperationHistory` 表 + DAO + 前端弹窗），Cleaner 应复用相同模式。
+
+## 设计决策
+
+| 决策项   | 选择                                                         | 理由                                                                                |
+| -------- | ------------------------------------------------------------ | ----------------------------------------------------------------------------------- |
+| 表结构   | 独立建表，不与 Extractor 共用                                | Cleaner 数据结构差异大（双层、物料级详情），独立更清晰                              |
+| 记录粒度 | 执行 + 订单 + 物料三层                                       | 执行表存全局信息，订单表存订单汇总，物料表存操作明细                                |
+| 批次标识 | `BatchId`（UUID），与 Extractor 一致                         | 标准、简洁，不需要嵌入时间戳                                                        |
+| 重试记录 | 不覆盖，每次尝试独立写入，用 `AttemptNumber` 区分            | 保留完整审计链，为后续智能跳过提供数据基础                                          |
+| 报告文件 | 移除 Markdown 报告和 RustFS 上传                             | 数据库完全替代，报告相关代码（CleanerReportGenerator、generateAndUploadReport）删除 |
+| 前端历史 | 独立 CleanerOperationHistoryModal，复用 Extractor 的 UI 模式 | 放在 CleanerPage 上，与 Extractor 的"操作历史"按钮对齐                              |

+### 数据示例
+
+首次执行到第 80 个订单时崩溃，外层重试成功完成全部 211 个订单：
+
+**CleanerExecution**
+
+```
+BatchId=uuid-1, Attempt=1, Status=crashed,  TotalOrders=211, Processed=80,  ...
+BatchId=uuid-1, Attempt=2, Status=success,  TotalOrders=211, Processed=211, ...
+```
+
+**CleanerOrderHistory**（Attempt=1 中部分记录）
+
+```
+BatchId=uuid-1, Attempt=1, Order=SC001, Status=success, Deleted=5, Skipped=1
+BatchId=uuid-1, Attempt=1, Order=SC080, Status=crashed, Error=查询超时
+```
+
+**CleanerOrderHistory**（Attempt=2 中部分记录）
+
+```
+BatchId=uuid-1, Attempt=2, Order=SC001, Status=success, Deleted=5, Skipped=1
+BatchId=uuid-1, Attempt=2, Order=SC080, Status=success, Deleted=3, Skipped=0
+BatchId=uuid-1, Attempt=2, Order=SC211, Status=success, Deleted=2, Skipped=0
+```
+
+**CleanerMaterialDetail**（SC080 在 Attempt=2 中的物料）
+
+```
+BatchId=uuid-1, Attempt=2, Order=SC080, Material=MAT-001, Result=deleted
+BatchId=uuid-1, Attempt=2, Order=SC080, Material=MAT-002, Result=skipped, Reason=不可删除
+```
+
+## 写入时机
+
+```
+用户点击"执行清理"
+  → IPC: cleaner:run
+    → cleaner-handler.ts
+      → ① BatchId = randomUUID()
+      → ② 插入 CleanerExecution（Status=pending）
+      → ③ 插入 CleanerOrderHistory（所有订单，Status=pending）
+      → ④ 执行清理（CleanerApplicationService.runCleaner）
+      → ⑤ 更新 CleanerExecution（Status=success/failed/partial/crashed）
+      → ⑥ 更新 CleanerOrderHistory（每个订单的结果）
+      → ⑦ 插入 CleanerMaterialDetail（每个物料的操作明细）
+      → ⑧ 如果 crashed → 外层重试
+         → 插入新的 CleanerExecution（AttemptNumber=2, Status=pending）
+         → 插入新的 CleanerOrderHistory（AttemptNumber=2, Status=pending）
+         → 重新执行
+         → 更新执行表和订单表状态
+         → 插入物料明细
+```
+
+- 步骤 ②③：在 `cleaner-handler.ts` 中，执行前写入，记录操作人、全局配置、待处理订单
+- 步骤 ⑤⑥⑦：在 `CleanerApplicationService` 中，执行完成后回调 DAO 写入结果
+- 步骤 ⑧：外层重试时，三张表都新增 AttemptNumber=2 的记录，首次尝试的数据完整保留
+
+## 变更清单
+
+### 新增文件

+1. **`src/main/services/database/cleaner-operation-history-dao.ts`**
+   - `CleanerOperationHistoryDAO` 类
+   - 执行表操作：insertExecution、updateExecutionStatus
+   - 订单表操作：insertOrderRecords、updateOrderStatus
+   - 物料表操作：insertMaterialDetails
+   - 查询操作：getBatches、getBatchDetails（含订单+物料）、deleteBatch
+   - 参考 `ExtractorOperationHistoryDAO` 的模式，表名使用 `ERPAuto.CleanerExecution`、`ERPAuto.CleanerOrderHistory`、`ERPAuto.CleanerMaterialDetail`
+
+2. **`src/main/types/cleaner-history.types.ts`**
+   - `CleanerExecutionRecord`、`CleanerOrderRecord`、`CleanerMaterialRecord`

+
+3. **`src/renderer/src/components/CleanerOperationHistoryModal.tsx`**
+   - 操作历史弹窗，复用 ExtractorOperationHistoryModal 的 UI 模式
+   - 批次列表（按 BatchId 聚合，显示操作时间、用户、状态、成功/失败数，区分多次尝试）
+   - 展开明细（订单列表，每订单的删除/跳过/失败数）
+   - 物料级详情（第二层展开，显示每个物料的操作结果）
+   - 管理员可按用户筛选、可删除批次
+
+### 修改文件
+
+4. **`src/main/ipc/cleaner-handler.ts`**
+   - `CLEANER_RUN` handler 中：执行前插入 execution + order 的 pending 记录，执行后更新结果
+   - 新增 IPC handlers：`CLEANER_HISTORY_BATCHES`、`CLEANER_HISTORY_DETAILS`、`CLEANER_HISTORY_DELETE`
+
+5. **`src/main/services/cleaner/cleaner-application-service.ts`**
+   - `runCleaner` 接收 `batchId` 参数
+   - 移除 `generateExecutionId()` 函数
+   - 移除 `generateAndUploadReport()` 方法
+   - 移除 `executionId` 相关逻辑
+   - 外层重试时，通过 DAO 写入 AttemptNumber=2 的执行记录和订单记录，不覆盖首次尝试
+   - 执行完成后回调 DAO 写入订单结果和物料明细
+
+6. **`src/main/ipc/index.ts`**
+   - 注册新的 cleaner history IPC handlers
+
+7. **`src/preload/api/cleaner.ts`**
+   - 新增 IPC 调用方法：getBatches、getBatchDetails、deleteBatch
+
+8. **`src/preload/index.d.ts`**
+   - `CleanerAPI` 接口新增 getBatches、getBatchDetails、deleteBatch 类型声明
+
+9. **`src/renderer/src/pages/CleanerPage.tsx`**

+   - 引入 CleanerOperationHistoryModal
+
+### 删除文件
+
+10. **`src/main/services/report/cleaner-report-generator.ts`**
+    - 整个文件删除，报告生成逻辑不再需要
+
+### 可选清理
+
+11. **`src/renderer/src/components/ReportViewerDialog.tsx`**
+    - 基于 RustFS 文件的报告查看器，Cleaner 不再使用
+    - 如果 Extractor 不共用此组件，可删除
+
+12. **`src/renderer/src/components/ReportAnalysisDialog.tsx`**
+    - 基于报告文件的分析，Cleaner 不再使用
+    - 后续可基于数据库重新实现统计分析
+

+# Cleaner 数据库持久化实施计划
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** 将 Cleaner 的执行记录从 Markdown 文件持久化迁移到数据库（三张表：执行级、订单级、物料级），并在前端新增操作历史弹窗。
+
+**Architecture:** 新建 `CleanerOperationHistoryDAO` 操作三张表（`ERPAuto.CleanerExecution`、`ERPAuto.CleanerOrderHistory`、`ERPAuto.CleanerMaterialDetail`），通过新增 IPC handlers 暴露给前端。执行前写入 pending 记录，执行后更新结果和物料明细。外层重试时新增 AttemptNumber=2 的记录，不覆盖首次尝试。移除 Markdown 报告生成和 RustFS 上传链路。
+
+**Tech Stack:** TypeScript, Electron IPC, SQL (MySQL/SQL Server/PostgreSQL via existing DAO+dialect pattern), React

+## Task 1: 新增类型定义
+
+**Files:**
+
+- Create: `src/main/types/cleaner-history.types.ts`
+
+**Step 1: 创建类型文件**
+
+```typescript
+// src/main/types/cleaner-history.types.ts

+
+## Task 2: 新增 DAO 层
+
+**Files:**
+
+- Create: `src/main/services/database/cleaner-operation-history-dao.ts`
+
+**Step 1: 创建 DAO 文件**
+
+参考 `extractor-operation-history-dao.ts` 的模式（`create()` 获取数据库连接、`createDialect()` 处理 SQL 方言、`trackDuration()` 记录耗时）。表名使用 `ERPAuto` schema。
+
+关键方法：
+
+```typescript
+export class CleanerOperationHistoryDAO {
+  private dbService: IDatabaseService | null = null
+  private dialect: SqlDialect | null = null
+
+  // ===== 执行表 =====
+  private getExecutionTableName(): string {
+    return this.getDialect().quoteTableName('ERPAuto', 'CleanerExecution')
+  }
+
+  async insertExecution(input: InsertCleanerExecutionInput): Promise<boolean>
+  async updateExecutionStatus(
+    batchId: string,
+    attemptNumber: number,
+    status: string,
+    ordersProcessed: number,
+    materialsDeleted: number,
+    materialsSkipped: number,
+    materialsFailed: number,
+    uncertainDeletions: number,
+    endTime: Date,
+    errorMessage?: string
+  ): Promise<boolean>
+
+  // ===== 订单表 =====
+  private getOrderTableName(): string {
+    return this.getDialect().quoteTableName('ERPAuto', 'CleanerOrderHistory')
+  }
+
+  async insertOrderRecords(
+    batchId: string,
+    attemptNumber: number,
+    orders: InsertOrderInput[]
+  ): Promise<boolean>
+  async updateOrderStatus(
+    batchId: string,
+    attemptNumber: number,
+    orderNumber: string,
+    status: string,
+    materialsDeleted: number,
+    materialsSkipped: number,
+    materialsFailed: number,
+    uncertainDeletions: number,
+    retryCount: number,
+    retrySuccess: boolean,
+    errorMessage?: string
+  ): Promise<boolean>
+
+  // ===== 物料表 =====
+  private getMaterialTableName(): string {
+    return this.getDialect().quoteTableName('ERPAuto', 'CleanerMaterialDetail')
+  }
+
+  async insertMaterialDetails(
+    batchId: string,
+    attemptNumber: number,
+    details: InsertMaterialDetailInput[]
+  ): Promise<boolean>
+
+  // ===== 查询 =====
+  async getBatches(
+    userId?: number,
+    options?: GetCleanerBatchesOptions
+  ): Promise<CleanerBatchStats[]>
+  async getBatchDetails(
+    batchId: string
+  ): Promise<{ executions: CleanerExecutionRecord[]; orders: CleanerOrderRecord[] }>
+  async getMaterialDetails(
+    batchId: string,
+    attemptNumber: number,
+    orderNumber: string
+  ): Promise<CleanerMaterialRecord[]>
+
+  // ===== 删除 =====
+  async deleteBatch(
+    batchId: string,
+    requestingUserId: number,
+    isAdmin: boolean
+  ): Promise<{ success: boolean; error?: string }>
+
+  // ===== 列询执行级记录 =====
+  async getMaterialDetails(
+    batchId: string,
+    attemptNumber: number,
+    orderNumber: string
+  ): Promise<CleanerMaterialRecord[]>
+
+  // ===== 删除 =====
+  async deleteBatch(
+    batchId: string,
+    requestingUserId: number,
+    isAdmin: boolean
+  ): Promise<{ success: boolean; error?: string }>
+  async disconnect(): Promise<void>
+}
+```
+
+`getBatches` 查询逻辑：
+
+- `GROUP BY BatchId`，取 `MAX(AttemptNumber)` 对应的执行记录状态作为最终状态
+- 汇总订单级的 success/failed 计数
+- 支持 userId 过滤（普通用户）和 usernames 过滤（管理员）
+- 支持分页
+
+`getBatchDetails` 查询逻辑：
+
+- 返回某 BatchId 下所有 execution 记录 + order 记录
+- 前端用 attemptNumber 区分不同尝试
+
+每个 INSERT/UPDATE 使用 `trackDuration()` 包裹，error handling 与 Extractor DAO 一致。
+
+**Step 2: 验证类型检查通过**
+
+Run: `npm run typecheck`
+Expected: PASS
+
+**Step 3: Commit**

+## Task 3: 新增 IPC channels
+
+**Files:**
+
+- Modify: `src/shared/ipc-channels.ts`
+
+**Step 1: 添加 cleaner history channels**
+
+在现有的 `CLEANER_PROGRESS` 之后添加：
+
+```typescript
+// Cleaner history

+CLEANER_HISTORY_GET_BATCH_DETAILS: 'cleanerHistory:getBatchDetails',
+CLEANER_HISTORY_GET_MATERIAL_DETAILS: 'cleanerHistory:getMaterialDetails',
+CLEANER_HISTORY_DELETE_BATCH: 'cleanerHistory:deleteBatch',
+```

+
+## Task 4: 新增 IPC handler
+
+**Files:**
+
+- Create: `src/main/ipc/cleaner-history-handler.ts`
+- Modify: `src/main/ipc/index.ts` — 注册新 handler
+
+**Step 1: 创建 cleaner-history-handler.ts**
+
+参考 `operation-history-handler.ts` 的模式。四个 handler：
+
+- `CLEANER_HISTORY_GET_BATCHES`：获取批次列表，Admin 看全部，User 看自己的
+- `CLEANER_HISTORY_GET_BATCH_DETAILS`：获取某个批次的执行记录和订单记录
+- `CLEANER_HISTORY_GET_MATERIAL_DETAILS`：获取某个订单的物料明细
+- `CLEANER_HISTORY_DELETE_BATCH`：删除批次，权限校验与 Extractor 一致
+
+```typescript
+export function registerCleanerHistoryHandlers(): void {
+  const dao = new CleanerOperationHistoryDAO()
+
+  ipcMain.handle(
+    IPC_CHANNELS.CLEANER_HISTORY_GET_BATCHES,
+    async (event, options?: GetCleanerBatchesOptions): Promise<IpcResult<CleanerBatchStats[]>> => {

+      // ... 权限校验后删除三张表的记录
+    }
+  )
+}

+
+## Task 5: 新增 Preload API
+
+**Files:**
+
+- Modify: `src/preload/api/cleaner.ts` — 新增 history 方法
+- Modify: `src/preload/index.d.ts` — 新增类型声明
+
+**Step 1: 在 cleaner.ts 中新增 history 方法**
+
+```typescript
+import type {
+  CleanerBatchStats,
+  CleanerExecutionRecord,
+  CleanerOrderRecord,
+  CleanerMaterialRecord,
+  GetCleanerBatchesOptions
+} from '../../main/types/cleaner-history.types'

+## Task 6: 改造 CleanerApplicationService — 写入数据库记录
+
+**Files:**
+
+- Modify: `src/main/services/cleaner/cleaner-application-service.ts`
+
+这是核心变更。`runCleaner` 方法需要：
+
+**Step 1: 修改 runCleaner 签名，接收 batchId 和 DAO**
+
+```typescript
+async runCleaner(
+  eventSender: WebContents,
+  input: CleanerInput,
+  batchId: string,
+  historyDao: CleanerOperationHistoryDAO
+): Promise<CleanerResult>
+```
+
+**Step 2: 移除报告相关代码**
+
+- 删除 `import { app } from 'electron'`（仅用于 `app.getVersion()`）
+- 删除 `generateExecutionId()` 函数
+- 删除 `generateAndUploadReport()` 方法
+- 删除所有 `executionId` 相关变量和日志
+
+**Step 3: 插入 pending 订单记录**
+
+在登录成功后、执行清理前，调用 `historyDao.insertOrderRecords(batchId, 1, orders)` 写入 pending 状态的订单记录。
+
+**Step 4: 执行后更新订单记录和写入物料明细**
+
+清理完成后遍历 `result.details`（`OrderCleanDetail[]`），对每个订单：
+
+- 调用 `historyDao.updateOrderStatus(...)` 更新订单结果
+- 调用 `historyDao.insertMaterialDetails(...)` 写入物料明细（skipped + failed 材料全部写入）
+
+**Step 5: 更新执行记录状态**
+
+调用 `historyDao.updateExecutionStatus(batchId, 1, ...)` 更新为最终状态。
+
+**Step 6: 外层重试改造**
+
+当 `result.crashed` 时：
+
+1. 调用 `historyDao.updateExecutionStatus(batchId, 1, 'crashed', ...)` 标记首次尝试为 crashed
+2. 调用 `historyDao.insertExecution({ batchId, attemptNumber: 2, ... })` 创建第二次尝试
+3. 调用 `historyDao.insertOrderRecords(batchId, 2, orders)` 写入第二次尝试的 pending 订单
+4. 重新登录并执行
+5. 执行后更新 AttemptNumber=2 的订单和物料记录
+
+**Step 7: 验证类型检查通过**
+
+Run: `npm run typecheck`
+Expected: PASS
+
+**Step 8: Commit**
+
+```

+
+## Task 7: 改造 cleaner-handler.ts — 执行前后写入
+
+**Files:**
+
+- Modify: `src/main/ipc/cleaner-handler.ts`
+
+**Step 1: 修改 CLEANER_RUN handler**
+
+在调用 `cleanerService.runCleaner()` 之前：
+
+1. 获取当前用户信息
+2. `batchId = randomUUID()`
+3. 创建 `CleanerOperationHistoryDAO` 实例
+4. 调用 `dao.insertExecution({ batchId, attemptNumber: 1, userId, username, isDryRun, totalOrders, appVersion })`
+
+将 `batchId` 和 `dao` 传入 `runCleaner()`。
+
+执行完成后（无论成功失败），更新执行记录的最终状态。
+
+**Step 2: 移除 app.getVersion() 调用**
+
+`appVersion` 改为在 handler 层获取（因为 handler 已有 electron 访问权限），传给 DAO。
+
+**Step 3: 验证类型检查通过**
+
+Run: `npm run typecheck`
+Expected: PASS
+
+**Step 4: Commit**
+
+```
+refactor(cleaner): write execution records to database in IPC handler
+```
+

+
+## Task 8: 删除 Markdown 报告生成器
+
+**Files:**
+
+- Delete: `src/main/services/report/cleaner-report-generator.ts`
+
+**Step 1: 删除文件**
+
+删除 `cleaner-report-generator.ts`。
+
+**Step 2: 检查是否有其他文件引用它**
+
+搜索 `cleaner-report-generator` 或 `CleanerReportGenerator`，如有引用则一并移除（主要是 `cleaner-application-service.ts` 中已删除的 import）。
+
+**Step 3: 验证编译通过**
+
+Run: `npm run typecheck`
+Expected: PASS
+
+**Step 4: Commit**

+
+## Task 9: 前端 — 新增操作历史弹窗
+
+**Files:**
+
+- Create: `src/renderer/src/components/CleanerOperationHistoryModal.tsx`
+- Modify: `src/renderer/src/pages/CleanerPage.tsx`
+
+**Step 1: 创建 CleanerOperationHistoryModal**
+
+参考 `ExtractorOperationHistoryModal.tsx` 的 UI 模式和代码结构。关键差异：
+
+- 数据源使用 `window.electron.cleaner.getHistoryBatches()` 等新 API
+- 批次列表增加"尝试次数"列和"模拟运行"标识
+- 展开明细时，顶部显示执行级信息（尝试次数、crashed 状态等）
+- 订单表格增加 deleted/skipped/failed/uncertain 列
+- 订单行可再次展开查看物料明细（调用 `getHistoryMaterialDetails`）
+- 管理员按用户筛选、删除功能与 Extractor 一致
+
+**Step 2: 在 CleanerPage 中添加"操作历史"按钮和弹窗**
+
+- 在 `CleanerToolbar` 中添加"操作历史"按钮（或直接在 CleanerPage 添加）
+- 引入 `CleanerOperationHistoryModal` 组件
+- 传入 `user` 和 `isOpen/onClose` 控制
+
+**Step 3: 验证类型检查通过**
+
+Run: `npm run typecheck`
+Expected: PASS
+
+**Step 4: Commit**
+
+```
+feat(cleaner): add operation history modal with database-backed records
+```
+
+---
+
+## Task 10: 更新 renderer 类型定义
+
+**Files:**
+
+- Modify: `src/renderer/src/hooks/cleaner/types.ts`
+
+**Step 1: 添加 history 相关类型**
+
+在 types.ts 中添加前端需要的类型（或直接从 `cleaner-history.types.ts` import，根据项目的前端类型引用模式决定）。
+
+**Step 2: 验证类型检查通过**
+
+Run: `npm run typecheck`
+Expected: PASS
+
+**Step 3: Commit**
+
+```
+feat(cleaner): add renderer types for cleaner operation history
+```
+
+---
+
+## Task 11: 清理旧代码
+
+**Files:**
+
+- Modify: `src/renderer/src/hooks/cleaner/types.ts` — 移除 `CleanerReportData.crashed`（如果不再需要）
+- 检查 `ReportViewerDialog.tsx`、`ReportAnalysisDialog.tsx` 是否仍被 Cleaner 使用
+
+**Step 1: 清理 renderer 中不再需要的类型**
+
+- `CleanerReportData` 中如果 `crashed` 字段已无用，移除
+- 确认 `CleanerPhase` 的 `'retry'` 值是否仍需要（前端进度通知仍在使用，保留）
+
+**Step 2: 评估 ReportViewerDialog 和 ReportAnalysisDialog**
+
+这两个组件目前用于查看 Markdown 报告文件。如果 Cleaner 不再使用它们：
+
+- 在 CleanerPage 中移除相关按钮和引用
+- 不删除组件本身（Extractor 可能仍在使用，后续统一清理）
+
+**Step 3: 验证编译和类型检查通过**
+
+Run: `npm run typecheck && npm run lint`
+Expected: PASS
+
+**Step 4: Commit**
+
+```
+chore(cleaner): clean up legacy report-related code
+```

+
+## Task 12: 集成测试
+
+**Step 1: 运行完整类型检查**
+
+Run: `npm run typecheck`
+Expected: PASS
+
+**Step 2: 运行 lint**
+
+Run: `npm run lint`
+Expected: PASS
+
+**Step 3: 运行单元测试**
+
+Run: `npm run test`
+Expected: PASS
+
+**Step 4: 手动验证**
+
+1. 启动 `npm run dev`
+2. 在 Cleaner 页面执行一次清理（模拟运行）
+3. 检查数据库三张表是否正确写入
+4. 点击"操作历史"按钮，验证批次列表和详情展示
+5. 模拟崩溃场景（如果可以），验证外层重试写入 AttemptNumber=2 的记录
+6. 用管理员账号验证用户筛选和删除功能
+

+
+## 执行顺序
+
+```
+Task 1 (types) → Task 2 (DAO) → Task 3 (IPC channels) → Task 4 (IPC handler)
+  → Task 5 (preload) → Task 6 (CleanerApplicationService) → Task 7 (cleaner-handler)
+  → Task 8 (删除报告生成器) → Task 10 (renderer types) → Task 9 (前端弹窗)
+  → Task 11 (清理) → Task 12 (集成测试)

+# Cleaner 外层重试机制设计
+
+## 背景
+
+当 CleanerService.performCleanup 的主循环抛出未捕获异常时（如查询超时、浏览器崩溃），代码进入 outer catch 块，直接返回 partial result。位于 try 块后半段的订单级重试逻辑（retryFailedOrders）永远没有机会执行。
+
+典型场景：211 个订单中处理到第 80 个时，查询列表页等待表格行超时 → Cleaner failed → 浏览器被关闭 → 剩余 131 个订单未处理 → 无重试。
+
+## 设计决策
+
+| 决策项       | 选择                      | 理由                             |
+| ------------ | ------------------------- | -------------------------------- |
+| 重试层级     | CleanerApplicationService | 崩溃后浏览器不可用，必须重新登录 |
+| 重试范围     | 全部订单重新跑            | 简单可靠，物料删除是幂等操作     |
+| 最大重试次数 | 1 次                      | 覆盖瞬态故障，不过度消耗时间     |
+| 触发条件     | result.crashed === true   | 仅 outer catch 触发时才重试      |
+| 报告去重     | 执行 ID                   | 用户点击执行时生成，重试不变     |
+
+## 变更清单
+
+### 1. CleanerResult 新增字段
+
+**文件**: `src/main/types/cleaner.types.ts`
+
+```typescript
+export interface CleanerResult {
+  // ... 现有字段
+  crashed?: boolean // true = outer catch triggered, 流程级崩溃
+}
+```
+
+同步更新 `src/shared/types/cleaner.types.ts`（如有独立定义）和 preload 暴露的类型声明。
+
+### 2. CleanerService 标记崩溃
+
+**文件**: `src/main/services/erp/cleaner.ts`，line 375 的 catch 块
+
+```typescript
+} catch (error) {
+  const message = error instanceof Error ? error.message : 'Unknown error'
+  log.error('Cleaner failed', { ... })
+  result.errors.push(`Clean failed: ${message}`)
+  result.crashed = true  // ← 新增
+}
+```
+
+### 3. CleanerApplicationService 重试逻辑
+
+**文件**: `src/main/services/cleaner/cleaner-application-service.ts`
+
+在 `runCleaner()` 中，`cleaner.clean()` 返回后增加重试判断：
+
+```
+runCleaner(eventSender, input) {
+  const executionId = generateExecutionId()  // 用户点击时生成
+  const startTime = Date.now()
+
+  // 1. 获取 ERP 配置、数据库连接、订单解析（不变）
+  // 2. 登录 ERP（不变）
+
+  let result = await cleaner.clean(modifiedInput)
+
+  // === 外层重试 ===
+  if (result.crashed) {
+    log.warn('检测到流程级崩溃，准备外层重试', { executionId })
+
+    await authService.close()  // 关闭不可用的浏览器
+    authService = new ErpAuthService({...})
+    await authService.login()  // 重新登录
+
+    cleaner = new CleanerService(authService)
+    result = await cleaner.clean(modifiedInput)  // 全部订单重新跑
+  }
+
+  // 3. 生成报告（使用 executionId 作为文件名一部分，避免重复）
+  await this.generateAndUploadReport(input, result, startTime, executionId)
+  return result
+}
+```
+
+### 4. 执行 ID 生成规则
+
+格式: `CLN-{yyyyMMddHHmmss}-{4位随机字母}`
+
+示例: `CLN-20260410112930-A7FK`
+
+生成时机: `runCleaner()` 入口处，在 ERP 登录之前。重试时同一个 executionId 不变。
+
+用途:
+
+- 报告文件名: `cleaner-report-CLN-20260410112930-A7FK.md`
+- RustFS 存储路径中包含该 ID，重试时覆盖同一文件
+- 报告内容中显示该 ID
+
+### 5. 报告增强
+
+**文件**: `src/main/services/report/cleaner-report-generator.ts`
+
+在执行摘要表格中新增字段:
+
+```markdown
+| 项目         | 值                        |
+| ------------ | ------------------------- | ------ |
+| **执行 ID**  | `CLN-20260410112930-A7FK` | ← 新增 |
+| **应用版本** | `1.11.1`                  | ← 新增 |
+| **执行时间** | `2026-04-10 11:29:30`     |
+| **执行模式** | `正式执行`                |
+| ...          | ...                       |
+```
+
+- **执行 ID**: 从 ReportOptions 传入
+- **应用版本**: `app.getVersion()`，沿用 logger 中已有的获取方式
+
+**ReportOptions 变更**:
+
+```typescript
+export interface ReportOptions {
+  dryRun: boolean
+  username: string
+  startTime: number
+  endTime: number
+  executionId: string // ← 新增
+  appVersion: string // ← 新增
+}
+```
+
+**报告文件名变更**:
+
+```
+旧: cleaner-report-2026-04-10-03-30-12.md
+新: cleaner-report-CLN-20260410112930-A7FK.md
+```
+
+重试时同一个 executionId 生成相同的文件名，本地文件和 RustFS 上传都会覆盖旧报告，无需额外去重逻辑。
+
+### 6. 进度通知增强
+
+重试时向前端发送进度通知，让用户知道正在重试:
+
+```typescript
+this.sendProgress(eventSender, '流程崩溃，正在重新登录并重试...', 0, {
+  phase: 'retry',
+  ...
+})
+```
+
+## 不涉及的部分
+
+- 前端 UI 变更（后续可单独做，展示重试状态）
+- IPC channel 变更
+- 内层重试逻辑（订单级/物料级）不变
+- 数据库 schema 变更

+# Cleaner v1.11.1 之后更新内容改进计划
+
+本文档基于 `v1.11.1..v1.12.3` 区间内已完成的前端审查结果整理而成，目标不是重复提交记录，而是为后续实现人员提供一份可以直接排期和落地的改进路线图。计划范围仅覆盖 Cleaner 相关前端改进，不扩展到主进程 DAO、IPC 或数据库结构重构。
+
+## 1. 背景与范围
+
+本计划覆盖 `v1.11.1` 之后到当前最新版本 `v1.12.3` 的 Cleaner 前端相关更新，重点关注以下变化：
+
+- 新增 Cleaner 操作历史弹窗
+- 用数据库持久化替代原有 Markdown 报告查看路径
+- 为执行结果补充失败与不确定删除统计
+- 引入 `React.lazy` 和 `BatchItem` 拆分来降低页面负担
+
+本次计划的核心目标是：
+
+- 先修复当前历史弹窗与执行结果展示中的稳定性问题
+- 再优化首屏加载和复杂列表交互性能
+- 最后补齐长期可维护性和可扩展性基础
+
+默认审查区间固定为 `v1.11.1..v1.12.3`，默认文档语言为中文，默认落点为 `docs/plans/`。
+
+## 2. 当前状态总结
+
+这轮更新已经做对了几件重要的事情：
+
+- Cleaner 历史记录已经完成数据库化，前端不再依赖旧的 Markdown 报告浏览流
+- `CleanerOperationHistoryModal` 被独立成单独组件，并通过 `BatchItem` 局部拆分降低兄弟节点联动重渲染
+- `CleanerPage` 已经开始使用 `React.lazy` 引入历史弹窗与执行报告相关组件
+- `ExecutionReportDialog` 已经补充 `materialsFailed` 和 `uncertainDeletions` 的展示能力
+
+这些改动说明整体方向是正确的，但从 React 最佳实践和后续维护成本看，当前实现仍然存在几个明确的改进空间：异步缓存策略不够稳、按需加载没有完全生效、复杂列表的扩展能力有限、前端回归保护不足。
+
+## 3. 主要改进项
+
+### P0 立刻修
+
+#### 3.1 修正历史详情与物料详情的缓存时机
+
+问题：
+
+- 当前历史批次详情和物料详情会在请求发起前就标记为“已加载”
+- 如果首次请求失败，后续再次展开不会重试，用户会长期看到空详情或误导性空状态
+
+目标：
+
+- 只在请求成功后写入缓存
+- 失败后允许再次展开重新请求
+- 在 UI 上保留现有交互风格，不做视觉重设计
+
+建议方向：
+
+- 将详情加载状态拆成 `idle / loading / success / error`
+- `detailsLoadedRef` 和 `loadedMaterialsRef` 只在成功后更新
+- 对失败场景提供自然重试路径，优先采用“再次展开即重试”的方式
+
+预期收益：
+
+- 避免瞬时请求失败被错误地永久缓存
+- 提高历史查看功能的稳定性和用户信任感
+
+#### 3.2 将 Cleaner 历史弹窗改成真正条件挂载
+
+问题：
+
+- 当前 `CleanerPage` 虽然使用了 `React.lazy`，但历史弹窗组件仍然会在页面渲染时被挂入树中
+- 这会导致对应 chunk 仍在首屏阶段就被加载，未达到真正按需加载的效果
+
+目标：
+
+- 历史弹窗只在用户打开时才参与渲染和加载
+- 避免进入 Cleaner 页面就提前下载历史功能代码
+
+建议方向：
+
+- 采用条件渲染而不是仅保留 `isOpen` 控制
+- 延续当前交互样式和打开方式，不调整页面布局
+
+预期收益：
+
+- 降低 Cleaner 页面的首屏负担
+- 更符合 `bundle-conditional` 类最佳实践
+
+#### 3.3 补最小前端回归测试
+
+问题：
+
+- 本轮新增了历史弹窗、异步详情展开和执行结果增强，但前端侧缺少对应测试保护
+
+目标：
+
+- 为关键行为建立最小可行回归测试
+- 优先补组件/行为测试，不新增端到端测试要求
+
+建议方向：
+
+- 覆盖历史弹窗未打开时不触发懒加载模块请求
+- 覆盖批次详情和物料详情首次失败后再次展开可重试
+- 覆盖管理员筛选切换后请求参数与结果一致
+
+预期收益：
+
+- 降低后续修复和优化时的回归风险
+- 为后续分页、交互优化提供安全网
+
+### P1 本周优化
+
+#### 3.4 为历史列表增加分页能力
+
+问题：
+
+- 当前历史列表和明细表格按全量数据渲染，随着批次数量、订单数量和物料数量增加，性能风险会上升
+
+目标：
+
+- 让历史列表在数据增长后仍保持可接受的打开和滚动体验
+
+建议方向：
+
+- 默认优先采用分页，不先引入虚拟列表库
+- 先做批次列表分页，再评估是否需要对订单或物料明细做进一步优化
+
+预期收益：
+
+- 控制渲染体量
+- 降低复杂列表在中等数据规模下的卡顿风险
+
+#### 3.5 管理员筛选切换使用 `startTransition`
+
+问题：
+
+- 管理员切换用户筛选时会立即触发批次列表刷新，后续数据量增长后可能影响点击反馈
+
+目标：
+
+- 保持筛选按钮点击响应流畅
+- 将非紧急更新降级处理
+
+建议方向：
+
+- 将筛选触发的列表刷新包装到 `startTransition`
+- 保持现有筛选交互模型不变
+
+预期收益：
+
+- 降低筛选切换时的阻塞感
+- 更符合 React 对非紧急更新的建议用法
+
+#### 3.6 收敛重复派生计算
+
+问题：
+
+- 当前实现中存在多处基于 `orders` 和 `currentAttempt` 的重复 `filter/map`
+- 数据规模扩大后，这些重复遍历会逐步放大渲染成本
+
+目标：
+
+- 让渲染中的数据派生更集中、更可读
+
+建议方向：
+
+- 将当前 attempt 对应订单集合收敛成单一派生结果
+- 复制列内容等行为复用同一份派生数据
+
+预期收益：
+
+- 降低不必要的重复计算
+- 让 `BatchItem` 的渲染路径更容易维护
+
+#### 3.7 优化执行报告的结果语义
+
+问题：
+
+- 当前执行报告的标题和成功态仍主要依赖 `errors`
+- 当存在 `materialsFailed` 或 `uncertainDeletions` 时，结果表达仍可能显得过于乐观
+
+目标：
+
+- 让执行结果清楚区分成功、部分成功、失败、需人工确认
+
+建议方向：
+
+- 重新定义结果态判定优先级
+- 在不重做 UI 视觉设计的前提下，优化标题、说明文案和结果提示条
+
+预期收益：
+
+- 降低误判执行结果的风险
+- 让失败和不确定删除场景更容易被用户注意到
+
+### P2 后续演进
+
+#### 3.8 统一状态映射定义
+
+问题：
+
+- 当前状态的 label、icon、style 已有集中趋势，但仍是组件内局部定义
+- 后续新增状态时容易出现展示不一致
+
+目标：
+
+- 用统一的受类型约束的映射管理状态展示
+
+建议方向：
+
+- 抽离共享状态映射
+- 覆盖 batch、execution、order、material 这几类状态展示
+
+预期收益：
+
+- 降低重复定义
+- 提高新增状态时的一致性和可维护性
+
+#### 3.9 补无障碍语义
+
+问题：
+
+- 当前批次展开和订单展开更多依赖点击容器，语义和键盘可达性还有提升空间
+
+目标：
+
+- 让复杂历史弹窗具备更清晰的交互语义
+
+建议方向：
+
+- 使用真实按钮作为展开触发器
+- 增加 `aria-expanded`、`aria-controls` 等属性
+
+预期收益：
+
+- 提升键盘交互和屏幕阅读器兼容性
+- 为后续复杂交互维护提供更稳定语义基础
+
+#### 3.10 规划历史查询的扩展能力
+
+问题：
+
+- 当前查询能力主要围绕固定数量批次列表和基础筛选
+- 如果历史功能继续增强，前端会越来越依赖更丰富的查询条件
+
+目标：
+
+- 为后续历史功能演进预留明确方向
+
+建议方向：
+
+- 预留时间范围筛选
+- 预留状态筛选
+- 延续服务端分页方向，而不是继续扩大前端一次性加载量
+
+预期收益：
+
+- 让后续功能迭代有稳定扩展路径
+- 避免复杂度持续堆积在当前单一弹窗实现中
+
+## 4. 推荐执行顺序
+
+建议按以下顺序推进：
+
+1. 先修 `P0`，优先处理缓存时机错误和按需加载未完全生效的问题
+2. 在 `P0` 修复完成后补最小前端回归测试，锁住关键行为
+3. 再做 `P1`，先分页，再处理 `startTransition` 和重复派生计算
+4. 最后进入 `P2`，统一状态映射、补无障碍语义，并规划历史查询扩展能力
+
+这个顺序的原则是：先修稳定性，再做性能，再做长期演进。
+
+## 5. 完成标准
+
+本计划相关改进完成后，至少应满足以下验收标准：
+
+- 历史弹窗未打开时，不触发对应懒加载模块请求
+- 批次详情或物料详情首次请求失败后，用户再次展开可重新请求
+- 用户筛选切换后，列表数据与筛选条件一致
+- 执行报告在存在 `materialsFailed` 或 `uncertainDeletions` 时，不再展示为完全成功
+- `npm run typecheck` 通过
+- 相关前端测试通过
+- Cleaner 页面关键路径手工验证通过，包括：
+  - 打开历史弹窗
+  - 展开批次详情
+  - 展开订单物料详情
+  - 切换管理员筛选
+  - 查看执行结果提示
+
+## 6. 默认方案与实施约束
+
+为避免后续实现阶段再次做不必要决策，本计划固定以下默认方案：
+
+- 历史列表优先采用分页，不先引入虚拟列表库
+- 历史弹窗继续保留现有交互样式，不做视觉重设计
+- 测试优先补组件/行为测试，不新增端到端测试要求
+- 本计划只覆盖 Cleaner 相关前端改进，不扩展到主进程 DAO、IPC、数据库结构重构
+
+如果后续版本继续围绕 Cleaner 历史功能扩展，可以在本计划基础上继续追加更细的实施文档，但不应改变本计划中 `P0 / P1 / P2` 的优先级顺序。

+# Cleaner Operation History - Full-Level Search Design
+
+Date: 2026-04-17
+
+## Summary
+
+Add a full-level search feature to `CleanerOperationHistoryModal` that allows users to search across batches, orders, and materials by entering a single keyword. A new backend search API returns pre-joined three-level nested data, and the frontend renders it with keyword highlighting.
+
+## Interaction Design
+
+- **Search bar**: placed in the toolbar area, above the user filter chips, with a search icon and clear button.
+- **Trigger**: press Enter or click the search button (no per-keystroke requests).
+- **Search mode behavior**:
+  - Hides pagination controls (results are cross-page).
+  - Matching batches auto-expand with orders and materials displayed directly.
+  - Non-matching levels are hidden.
+  - Clearing the search box returns to normal browse mode.
+- **Highlighting**: matched text wrapped in `<mark>` with yellow background.
+- **Empty result**: shows "未找到匹配的记录" message.
+- **Result cap**: backend limits to 20 batches; if truncated, shows a hint.
+
+## Search Fields
+
+| Level | Searchable fields |
+|-------|-------------------|
+| Batch | `batchId`, `username`, `status` |
+| Order | `orderNumber`, `productionId` |
+| Material | `materialCode`, `materialName` |
+
+## Data Flow
+
+```
+renderer: window.electron.cleaner.searchHistoryRecords(query, options)
+  → preload: expose searchHistoryRecords
+    → main IPC handler: cleaner:searchHistoryRecords
+      → service/DAO: searchCleanerHistory(searchQuery, options)
+        → DB query (JOIN batches + orders + materials, LIKE filter)
+```
+
+### Input Types
+
+```typescript
+interface SearchCleanerHistoryOptions {
+  query: string
+  usernames?: string[]    // admin-only user scope
+  limit?: number          // default 20
+}
+```
+
+### Response Type
+
+```typescript
+interface CleanerHistorySearchResult {
+  batches: Array<{
+    batch: CleanerHistoryBatchStats
+    executions: ExecutionRecord[]
+    orders: Array<{
+      order: CleanerHistoryOrderRecord
+      materials: CleanerHistoryMaterialRecord[]
+    }>
+  }>
+  totalMatches: number
+}
+```
+
+## Frontend Changes
+
+1. **Modal top-level**: add `searchMode` / `searchQuery` state; switch data source between search API and paginated API.
+2. **Toolbar**: add search input with Search icon and clear button.
+3. **BatchItem**: accept optional pre-loaded `orders` + `materials` props; skip lazy-loading in search mode.
+4. **Highlight utility**: `highlightText(text: string, query: string)` wraps matches in `<mark>` tags.
+5. **Footer**: hide pagination in search mode; show "找到 X 个批次" + "清除搜索" button.

+# Cleaner History Full-Level Search Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add full-level search (batch + order + material) to the CleanerOperationHistoryModal, using a new backend search API that returns pre-joined three-level nested data, with keyword highlighting in the frontend.
+
+**Architecture:** New `searchHistoryRecords` IPC channel goes through the existing DAO pattern. The DAO method performs a UNION-based SQL query across all three tables to find matching BatchIds, then fetches the full nested data for those batches. The frontend switches between browse mode (paginated) and search mode (full results) based on whether a search query is active.
+
+**Tech Stack:** TypeScript, React, SQL (MySQL/PostgreSQL/SQL Server via dialect abstraction), Electron IPC
+
+---
+
+### Task 1: Add search types to main process
+
+**Files:**
+- Modify: `src/main/types/cleaner-history.types.ts` (append at end)
+- Modify: `src/shared/ipc-channels.ts` (add new channel)
+
+**Step 1: Add search types to cleaner-history.types.ts**
+
+Append after the existing `GetCleanerBatchesOptions` interface:
+
+```typescript
+/** Search options for full-level history search */
+export interface SearchCleanerHistoryOptions {
+  query: string
+  usernames?: string[]
+  limit?: number
+}
+
+/** A single batch's full nested data for search results */
+export interface CleanerSearchBatchResult {
+  batch: CleanerBatchStats
+  executions: CleanerExecutionRecord[]
+  orders: Array<{
+    order: CleanerOrderRecord
+    materials: CleanerMaterialRecord[]
+  }>
+}
+
+/** Search response */
+export interface CleanerHistorySearchResult {
+  batches: CleanerSearchBatchResult[]
+  totalMatches: number
+}
+```
+
+**Step 2: Add IPC channel to ipc-channels.ts**
+
+In the `// Cleaner operation history` section, after `CLEANER_HISTORY_DELETE_BATCH`, add:
+
+```typescript
+CLEANER_HISTORY_SEARCH: 'cleanerHistory:search',
+```
+
+**Step 3: Verify TypeScript compiles**
+
+Run: `npx tsc --noEmit --project src/main/tsconfig.json 2>&1 | head -20`
+Expected: No new errors related to these types
+
+**Step 4: Commit**
+
+```bash
+git add src/main/types/cleaner-history.types.ts src/shared/ipc-channels.ts
+git commit -m "feat(cleaner-history): add search types and IPC channel"
+```
+
+---
+
+### Task 2: Add search DAO method
+
+**Files:**
+- Modify: `src/main/services/database/cleaner-operation-history-dao.ts`
+
+**Step 1: Add imports for new types**
+
+At the top of the file, add to the existing import from `../../types/cleaner-history.types`:
+
+```typescript
+import type {
+  // ... existing imports ...
+  SearchCleanerHistoryOptions,
+  CleanerSearchBatchResult,
+  CleanerHistorySearchResult
+} from '../../types/cleaner-history.types'
+```
+
+**Step 2: Add the searchBatches method to the DAO class**
+
+Add this method after the `getBatches` method (around line 707). The strategy:
+
+1. First, find matching BatchIds via a UNION query across all three tables using LIKE.
+2. Then fetch full nested data (batch stats, executions, orders, materials) for those batch IDs.
+
+```typescript
+// ==================== QUERY: SEARCH ====================
+
+/**
+ * Full-level search across batches, orders, and materials
+ * Uses UNION to find matching BatchIds, then fetches full nested data
+ */
+async searchBatches(
+  userId: number | undefined,
+  options: SearchCleanerHistoryOptions
+): Promise<CleanerHistorySearchResult> {
+  try {
+    const dbService = await this.getDatabaseService()
+    const execTable = this.getExecutionTableName()
+    const orderTable = this.getOrderTableName()
+    const materialTable = this.getMaterialTableName()
+    const dialect = this.getDialect()
+
+    const likeValue = `%${options.query}%`
+    const limit = options.limit ?? 20
+
+    // Step 1: Find distinct BatchIds matching the query across all tables
+    const batchIdSql = `
+      SELECT DISTINCT BatchId FROM (
+        SELECT e.BatchId FROM ${execTable} e
+          WHERE e.BatchId LIKE ${dialect.param(0)}
+             OR e.Username LIKE ${dialect.param(0)}
+             OR e.Status LIKE ${dialect.param(0)}
+        UNION ALL
+        SELECT o.BatchId FROM ${orderTable} o
+          WHERE o.OrderNumber LIKE ${dialect.param(0)}
+             OR o.ProductionId LIKE ${dialect.param(0)}
+        UNION ALL
+        SELECT m.BatchId FROM ${materialTable} m
+          WHERE m.MaterialCode LIKE ${dialect.param(0)}
+             OR m.MaterialName LIKE ${dialect.param(0)}
+      ) AS matched
+      ${userId !== undefined ? `WHERE BatchId IN (SELECT BatchId FROM ${execTable} WHERE UserId = ${dialect.param(1)})` : ''}
+      ${options.usernames && options.usernames.length > 0 ? `WHERE BatchId IN (SELECT BatchId FROM ${execTable} WHERE Username IN (${dialect.params(options.usernames.length)}))` : ''}
+    `
+
+    const batchIdParams: (string | number)[] = [likeValue]
+    if (userId !== undefined) {
+      batchIdParams.push(userId)
+    }
+    if (options.usernames && options.usernames.length > 0) {
+      batchIdParams.push(...options.usernames)
+    }
+
+    const batchIdResult = await trackDuration(
+      async () => await dbService.query(batchIdSql, batchIdParams),
+      {
+        operationName: 'CleanerOperationHistoryDAO.searchBatches.batchIds',
+        context: { operationType: 'SELECT', query: options.query }
+      }
+    )
+
+    const matchedBatchIds = batchIdResult.result.rows.map((r) => r.BatchId as string)
+
+    if (matchedBatchIds.length === 0) {
+      return { batches: [], totalMatches: 0 }
+    }
+
+    // Apply limit
+    const limitedBatchIds = matchedBatchIds.slice(0, limit)
+
+    // Step 2: For each batch, fetch full nested data in parallel
+    const batches: CleanerSearchBatchResult[] = []
+
+    for (const batchId of limitedBatchIds) {
+      // Fetch batch stats
+      const batchStatsArr = await this.getBatches(userId, { limit: 1 })
+      const batchStats = batchStatsArr.find((b) => b.batchId === batchId)
+      if (!batchStats) continue
+
+      // Fetch executions + orders
+      const details = await this.getBatchDetails(batchId)
+
+      // Fetch materials for all orders
+      const ordersWithMaterials = await Promise.all(
+        details.orders.map(async (order) => {
+          const materials = await this.getMaterialDetails(
+            batchId,
+            order.attemptNumber,
+            order.orderNumber
+          )
+          return { order, materials }
+        })
+      )
+
+      batches.push({
+        batch: batchStats,
+        executions: details.executions,
+        orders: ordersWithMaterials
+      })
+    }
+
+    return {
+      batches,
+      totalMatches: matchedBatchIds.length
+    }
+  } catch (error) {
+    log.error('Search batches error', {

+      query: options.query,
+      error: error instanceof Error ? error.message : String(error)
+    })
+    return { batches: [], totalMatches: 0 }
+  }
+}
+```
+
+**Step 3: Verify TypeScript compiles**
+
+Run: `npx tsc --noEmit --project src/main/tsconfig.json 2>&1 | head -20`
+Expected: No errors related to the DAO
+

+
+### Task 3: Add IPC handler for search
+
+**Files:**
+- Modify: `src/main/ipc/cleaner-history-handler.ts`
+
+**Step 1: Add new IPC handler**
+
+In `registerCleanerHistoryHandlers()`, after the `CLEANER_HISTORY_DELETE_BATCH` handler (before the closing log statement at the end), add:
+
+```typescript
+/**
+ * Search across all history levels (batches, orders, materials)
+ * Admin users search all records, regular users search only their own
+ */
+ipcMain.handle(
+  IPC_CHANNELS.CLEANER_HISTORY_SEARCH,
+  async (
+    _event,
+    options: SearchCleanerHistoryOptions
+  ): Promise<IpcResult<CleanerHistorySearchResult>> => {
+    return withErrorHandling(async () => {
+      const currentUser = SessionManager.getInstance().getUserInfo()
+
+      if (!currentUser) {
+        throw new Error('用户未登录')
+      }
+
+      if (!options.query || options.query.trim().length === 0) {
+        return { batches: [], totalMatches: 0 }
+      }
+
+      const userId = currentUser.userType === 'Admin' ? undefined : currentUser.id
+
+      log.info('Searching cleaner history', {
+        userId: currentUser.id,
+        userType: currentUser.userType,
+        query: options.query
+      })
+
+      return await dao.searchBatches(userId, {
+        ...options,
+        query: options.query.trim()
+      })
+    }, 'cleanerHistory:search')
+  }
+)
+```
+
+**Step 2: Update imports in cleaner-history-handler.ts**
+
+Add to the existing import from `../../types/cleaner-history.types`:
+
+```typescript
+import type {
+  // ... existing imports ...
+  SearchCleanerHistoryOptions,
+  CleanerHistorySearchResult
+} from '../types/cleaner-history.types'
+```
+
+**Step 3: Verify TypeScript compiles**
+
+Run: `npx tsc --noEmit --project src/main/tsconfig.json 2>&1 | head -20`
+
+**Step 4: Commit**
+
+```bash
+git add src/main/ipc/cleaner-history-handler.ts
+git commit -m "feat(cleaner-history): add search IPC handler"
+```
+
+---
+
+### Task 4: Expose search API in preload
+
+**Files:**
+- Modify: `src/preload/api/cleaner.ts`
+
+**Step 1: Add search method to cleanerApi**
+
+After the `deleteHistoryBatch` method, add:
+
+```typescript
+searchHistoryRecords: (
+  options: SearchCleanerHistoryOptions
+): Promise<IpcResult<CleanerHistorySearchResult>> =>
+  invokeIpc(IPC_CHANNELS.CLEANER_HISTORY_SEARCH, options),
+```
+
+**Step 2: Add imports**
+
+Add to the existing import from `../../main/types/cleaner-history.types`:
+
+```typescript
+import type {
+  // ... existing imports ...
+  SearchCleanerHistoryOptions,
+  CleanerHistorySearchResult
+} from '../../main/types/cleaner-history.types'
+```
+
+**Step 3: Verify TypeScript compiles**
+
+Run: `npx tsc --noEmit --project src/preload/tsconfig.json 2>&1 | head -20`
+
+**Step 4: Commit**
+
+```bash
+git add src/preload/api/cleaner.ts
+git commit -m "feat(cleaner-history): expose search API in preload"
+```
+
+---
+
+### Task 5: Add renderer-side types and highlight utility
+
+**Files:**
+- Modify: `src/renderer/src/hooks/cleaner/types.ts` (add search result types)
+- Create: `src/renderer/src/components/cleaner-history-highlight.tsx`
+
+**Step 1: Add search result types to renderer types**
+
+Append to `src/renderer/src/hooks/cleaner/types.ts`:
+
+```typescript
+// Search result types (mirrors main process types)
+
+export interface CleanerHistorySearchOrderResult {
+  order: CleanerHistoryOrderRecord
+  materials: CleanerHistoryMaterialRecord[]
+}
+
+export interface CleanerHistorySearchBatchResult {
+  batch: CleanerHistoryBatchStats
+  executions: CleanerHistoryExecutionRecord[]
+  orders: CleanerHistorySearchOrderResult[]
+}
+
+export interface CleanerHistorySearchResult {
+  batches: CleanerHistorySearchBatchResult[]
+  totalMatches: number
+}
+```
+
+**Step 2: Create highlight utility**
+
+Create `src/renderer/src/components/cleaner-history-highlight.tsx`:
+
+```tsx
+import React from 'react'
+
+/**
+ * Highlight matching text with a <mark> tag
+ * Case-insensitive matching of the query within text
+ */
+export function highlightText(text: string, query: string): React.ReactNode {
+  if (!query || !text) return text
+
+  const lowerText = text.toLowerCase()
+  const lowerQuery = query.toLowerCase()
+
+  const index = lowerText.indexOf(lowerQuery)
+  if (index === -1) return text
+
+  const before = text.substring(0, index)
+  const match = text.substring(index, index + query.length)
+  const after = text.substring(index + query.length)
+
+  return (
+    <>
+      {before}
+      <mark className="bg-yellow-200 text-inherit rounded px-0.5">{match}</mark>
+      {highlightText(after, query)}
+    </>
+  )
+}
+```
+
+**Step 3: Commit**
+
+```bash
+git add src/renderer/src/hooks/cleaner/types.ts src/renderer/src/components/cleaner-history-highlight.tsx
+git commit -m "feat(cleaner-history): add renderer search types and highlight utility"
+```
+
+---
+
+### Task 6: Integrate search into CleanerOperationHistoryModal
+
+**Files:**
+- Modify: `src/renderer/src/components/CleanerOperationHistoryModal.tsx`
+
+This is the largest task. The changes are:
+
+1. Add search state variables
+2. Add search bar UI to the toolbar
+3. Modify BatchItem to accept pre-loaded data in search mode
+4. Switch footer between pagination and search result summary
+
+**Step 1: Add new imports**
+
+Add to the lucide-react import:
+
+```typescript
+import { Search, X } from 'lucide-react'
+```
+
+Add the highlight utility and new types:
+
+```typescript
+import { highlightText } from './cleaner-history-highlight'
+import type { CleanerHistorySearchResult } from '../hooks/cleaner/types'
+```
+
+**Step 2: Add search state in the main modal component**
+
+After the existing state declarations (around line 651), add:
+
+```typescript
+const [searchQuery, setSearchQuery] = useState('')
+const [searchInput, setSearchInput] = useState('')
+const [searchResult, setSearchResult] = useState<CleanerHistorySearchResult | null>(null)
+const [isSearching, setIsSearching] = useState(false)
+```
+
+**Step 3: Add the search execution function**
+
+Add after `clearUserFilters`:
+
+```typescript
+const executeSearch = useCallback(async () => {
+  const trimmed = searchInput.trim()
+  if (!trimmed) {
+    setSearchQuery('')
+    setSearchResult(null)
+    return
+  }
+
+  setIsSearching(true)
+  setSearchQuery(trimmed)
+  try {
+    const options =
+      isAdmin && selectedUsers.length > 0
+        ? { query: trimmed, usernames: selectedUsers }
+        : { query: trimmed }
+
+    const result = await window.electron.cleaner.searchHistoryRecords(options)
+    if (result.success && result.data) {
+      setSearchResult(result.data)
+    } else {
+      setSearchResult({ batches: [], totalMatches: 0 })
+    }
+  } catch {
+    setSearchResult({ batches: [], totalMatches: 0 })
+  } finally {
+    setIsSearching(false)
+  }
+}, [searchInput, isAdmin, selectedUsers])
+
+const clearSearch = () => {
+  setSearchInput('')
+  setSearchQuery('')
+  setSearchResult(null)
+}
+```
+
+**Step 4: Add search bar UI**
+
+In the toolbar section, before the user filter `<div className="mb-3">` block, add the search input:
+
+```tsx
+{/* Search bar */}
+<div className="flex items-center gap-2 mb-3">
+  <div className="relative flex-1">
+    <Search size={16} className="absolute left-3 top-1/2 -translate-y-1/2 text-gray-400" />
+    <input
+      type="text"
+      value={searchInput}
+      onChange={(e) => setSearchInput(e.target.value)}
+      onKeyDown={(e) => {
+        if (e.key === 'Enter') void executeSearch()
+      }}
+      placeholder="搜索批次ID、订单号、物料编码/名称..."
+      className="w-full pl-9 pr-8 py-2 border border-gray-300 rounded-lg text-sm focus:outline-none focus:ring-2 focus:ring-blue-500 focus:border-transparent"
+      disabled={loading}
+    />
+    {searchInput && (
+      <button
+        className="absolute right-2 top-1/2 -translate-y-1/2 text-gray-400 hover:text-gray-600"
+        onClick={clearSearch}
+      >
+        <X size={16} />
+      </button>
+    )}
+  </div>
+  <button
+    className="px-4 py-2 bg-blue-600 text-white rounded-lg text-sm font-medium hover:bg-blue-700 disabled:opacity-50 transition-colors"
+    onClick={() => void executeSearch()}
+    disabled={isSearching || !searchInput.trim()}
+  >
+    {isSearching ? '搜索中...' : '搜索'}
+  </button>
+</div>
+```
+
+**Step 5: Modify the batch list section to support search mode**
+
+Replace the batch list section (the `<div className="flex-1 overflow-y-auto">` block) with conditional rendering:
+
+```tsx
+{/* Batch list */}
+<div className="flex-1 overflow-y-auto">
+  {searchQuery ? (
+    // Search mode
+    isSearching ? (
+      <div className="flex items-center justify-center h-32 text-gray-500">搜索中...</div>
+    ) : searchResult && searchResult.batches.length > 0 ? (
+      <div className="flex flex-col gap-3">
+        {searchResult.batches.map((result) => (
+          <BatchItem
+            key={result.batch.batchId}
+            batch={result.batch}
+            isAdmin={isAdmin}
+            onDelete={handleDeleteBatch}
+            onRequestDelete={requestDeleteConfirmation}
+            searchQuery={searchQuery}
+            preloadedExecutions={result.executions}
+            preloadedOrders={result.orders}
+          />
+        ))}
+      </div>
+    ) : (
+      <div className="flex items-center justify-center h-32 text-gray-500">
+        未找到匹配「{searchQuery}」的记录
+      </div>
+    )
+  ) : (
+    // Browse mode (existing logic)
+    <>
+      {loading && batches.length === 0 ? (
+        <div className="flex items-center justify-center h-32 text-gray-500">加载中...</div>
+      ) : batches.length === 0 ? (
+        <div className="flex items-center justify-center h-32 text-gray-500">暂无操作记录</div>
+      ) : (
+        <div className="flex flex-col gap-3">
+          {batches.map((batch) => (
+            <BatchItem
+              key={batch.batchId}
+              batch={batch}
+              isAdmin={isAdmin}
+              onDelete={handleDeleteBatch}
+              onRequestDelete={requestDeleteConfirmation}
+            />
+          ))}
+        </div>
+      )}
+    </>
+  )}
+</div>
+```
+
+**Step 6: Modify footer for search mode**
+
+Replace the footer section to conditionally show pagination or search summary:
+
+```tsx
+{/* Footer */}
+<div className="pt-4 border-t border-gray-200 flex justify-center">
+  {searchQuery && searchResult ? (
+    <div className="flex items-center gap-4">
+      <span className="text-sm text-gray-600">
+        找到 {searchResult.totalMatches} 个匹配批次
+        {searchResult.totalMatches > (searchResult.batches.length) &&
+          `（显示前 ${searchResult.batches.length} 个）`}
+      </span>
+      <button
+        className="px-4 py-2 text-sm text-gray-600 hover:text-gray-800 underline"
+        onClick={clearSearch}
+      >
+        清除搜索
+      </button>
+    </div>
+  ) : (
+    <div className="inline-flex items-center rounded-full border border-slate-200 bg-white p-1 shadow-sm">
+      {/* ... existing pagination buttons ... */}
+    </div>
+  )}
+</div>
+```
+
+**Step 7: Update BatchItem props and search mode rendering**
+
+Update `BatchItemProps` interface to support optional preloaded data:
+
+```typescript
+interface BatchItemProps {
+  batch: CleanerHistoryBatchStats
+  isAdmin: boolean
+  onDelete: (batchId: string) => void
+  onRequestDelete: (batchId: string) => Promise<boolean>
+  searchQuery?: string
+  preloadedExecutions?: ExecutionRecord[]
+  preloadedOrders?: Array<{
+    order: CleanerHistoryOrderRecord
+    materials: CleanerHistoryMaterialRecord[]
+  }>
+}
+```
+
+In the BatchItem component, when `searchQuery` is set and preloaded data is available:
+- Start expanded (`isExpanded` initial state: `!!searchQuery`)
+- Use preloaded executions/orders directly instead of fetching
+- Pass `searchQuery` to text rendering for highlighting
+
+**Step 8: Verify typecheck**
+
+Run: `npm run typecheck`
+
+**Step 9: Commit**
+

+## 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
+

+**适用范围：**
+
+- 完整用户旅程
+- UI 交互验证
+- 真实浏览器行为
+- 跨进程通信
+
+**Playwright 测试模式：**
+
+```typescript
+import { test, expect } from '@playwright/test'
+
+test('complete extraction workflow', async ({ page }) => {
+  // 1. 导航到登录页
+  await page.goto('http://localhost:5173/login')
+
+  // 2. 登录
+  await page.getByPlaceholder('用户名').fill('admin')
+  await page.getByPlaceholder('密码').fill('admin123')
+  await page.getByRole('button', { name: '登录' }).click()
+
+  // 3. 等待跳转
+  await expect(page).toHaveURL(/dashboard/)
+
+  // 4. 进入提取页面
+  await page.getByText('数据提取').click()
+
+  // 5. 输入订单号

+
+## 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%        |

+| `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'
+       })
+     }
+   })
+   ```
