+# 租赁业务全链路实施计划
+
+> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 让租赁全链路（合同→备车→交车→替换车→还车）按原型跑通，含共享验车模板、BPM审批、事件驱动联动。
+
+**Architecture:** 共享验车模板系统（4张表）放在 asset 模块，备车/交车/还车通过 `inspection_record_id` 关联。替换车模块从零构建。跨模块联动通过 Spring Event 解耦。BPM 审批继承现有 `BpmProcessInstanceStatusEventListener` 模式。
+
+**Tech Stack:** Spring Boot, MyBatis-Plus (`BaseMapperX`, `LambdaQueryWrapperX`), MapStruct, Flowable BPM, Vue 3 + TypeScript + Ant Design Vue + VXE Table
+
+**Spec:** `docs/superpowers/specs/2026-03-13-rental-full-chain-design.md`
+
+**Key paths:**

+### Task 5: 验车记录 Service
+
+**Files:**
+- Create: `$BE/service/inspection/InspectionTemplateService.java`
+- Create: `$BE/service/inspection/InspectionTemplateServiceImpl.java`
+- Create: `$BE/service/inspection/InspectionRecordService.java`
+- Create: `$BE/service/inspection/InspectionRecordServiceImpl.java`
+
+- [ ] **Step 1: 创建 InspectionTemplateService 接口**
+
+Methods: `createTemplate`, `updateTemplate`, `deleteTemplate`, `getTemplate`, `getTemplatePage`, `matchTemplate(Integer bizType, String vehicleType)`.
+
+- [ ] **Step 2: 实现 InspectionTemplateServiceImpl**
+
+`matchTemplate` 逻辑: 先按 bizType+vehicleType 精确匹配 → 无结果则 bizType+vehicleType IS NULL 匹配通用模板。CRUD 标准实现。保存时同步保存/更新 items（先删后插）。
+
+- [ ] **Step 3: 创建 InspectionRecordService 接口**
+
+```java
+public interface InspectionRecordService {
+    Long createRecord(Long templateId, Integer sourceType, Long sourceId, Long vehicleId);
+    Long cloneRecord(Long sourceRecordId, Integer newSourceType, Long newSourceId);
+    void updateRecordItem(InspectionRecordItemUpdateReqVO updateReqVO);
+    void completeRecord(Long recordId, String inspectorName);
+    InspectionRecordDetailVO getRecordDetail(Long recordId);
+    InspectionRecordDO getLatestRecord(Long vehicleId, Integer sourceType);
+}
+```
+
+- [ ] **Step 4: 实现 InspectionRecordServiceImpl**
+
+**createRecord**: 根据 templateId 查询所有 item → 创建 record（生成 recordCode） → 批量创建 record_item（从 template_item 复制 code/category/name/inputType，result/value 为 null）。
+
+**recordCode 生成**: `{prefix}-{yyyyMMdd}-{seq}`，prefix 根据 sourceType 决定（BC/JC/HC）。
+
+**cloneRecord**: 查源 record + items → 创建新 record（clonedFromId=源id，新 sourceType/sourceId）→ 复制所有 items（保留 result/value/remark/imageUrls）。
+
+**completeRecord**: 校验 record 存在 → 更新 status=2, inspectorName, inspectionTime=now()。检查必填项是否都有 result，没有则抛异常。
+
+**getRecordDetail**: 查 record + items → 组装 VO。

+**submitApproval**: 校验 status=DRAFT/REJECTED → 调用 `bpmProcessInstanceApi.createProcessInstance()` → 设 status=APPROVING。
+
+**updateApprovalStatus**: BPM 回调。APPROVE → status=APPROVED → 发布 `ReplacementApprovedEvent` → status=EXECUTING。REJECT → status=REJECTED。CANCEL → status=WITHDRAWN。

+- 生成 orderCode
+- 为每个 vehicleId 创建 ReturnOrderVehicleDO 子记录
+- 返回还车单ID
+

+- 创建还车单主记录（sourceType=2, sourceId=replacementId）
+- 创建一条车辆子记录
+- 返回还车单ID

+**startVehicleInspection(returnOrderVehicleId)**:
+- 查找该车最近的交车 inspection_record → 克隆为还车 record
+- 更新 ReturnOrderVehicleDO.inspectionRecordId
+
+**completeVehicleInspection(returnOrderVehicleId)**:
+- 调用 inspectionRecordService.completeRecord()
+- 检查该还车单所有车辆是否都验车完成 → 是则更新还车单 status=1(验车完成)

+**Files:**
+- Modify: `$FE/views/asset/return-order/index.vue` — 操作列增加"提交审批"、"撤回"
+- Modify: `$FE/views/asset/return-order/modules/form.vue` — 每辆车增加"开始验车"按钮 + InspectionForm
+
+- [ ] **Step 1: 更新 index.vue 操作列**
+
+按 status 和 approvalStatus 条件显示: 查看(始终)、编辑(待验车)、删除(待验车)、提交审批(验车完成+未提交)、撤回(审批中)。
+
+- [ ] **Step 2: 改造 form.vue 验车区域**
+
+车辆子表格中每行增加:
+- "开始验车"按钮（当 inspectionRecordId 为空时显示）→ 调用 `startVehicleInspection`
+- InspectionForm 组件（当 inspectionRecordId 存在时显示）
+- "完成验车"按钮 → 调用 `completeVehicleInspection`

+### Task 26: 前端构建验证
+
+- [ ] **Step 1: Build**
+
+```bash
+cd ../oneos-frontend && pnpm run build:antd
+```
+
+修复所有 TypeScript/构建错误直到通过。

+
+### Task 27: 全链路端到端验证
+
+- [ ] **Step 1: 后端编译**
+
+```bash
+cd ../oneos-backend && mvn compile -DskipTests
+```
+
+- [ ] **Step 2: 前端构建**
+
+```bash
+cd ../oneos-frontend && pnpm run build:antd
+```
+
+- [ ] **Step 3: 功能检查清单**
+
+验证以下流程可正常操作:
+1. 验车模板 CRUD — 创建模板+检查项
+2. 备车 — 创建备车单 → 自动生成验车记录 → 完成验车
+3. 交车 — 创建交车单 → 克隆备车验车记录 → 完成验车 → 操作列显示还车/替换车
+4. 替换车 — 从交车页面触发 → 自动填充 → 提交审批
+5. 还车 — 从交车页面触发 → 创建壳子 → 开始验车(克隆交车记录) → 完成验车 → 提交审批
+6. 永久替换审批通过 → 自动创建还车单
+
+- [ ] **Step 4: Final commit**
+
+```bash
+git add .
+git commit -m "feat: complete rental full-chain implementation"
+```
