+# 中介库导入改造后端实施计划
+
+> **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.
+> **执行约束：** 仓库约定不开 subagent，执行时使用 `superpowers:executing-plans`。
+
+**Goal:** 完成中介库后端导入改造，统一 `related_num_id` 为“关联中介本人证件号码”，新增“导入中介信息”和“导入中介实体关联关系”两条异步导入链路，并保证手工维护、统一查询和级联删除与新语义一致。
+
+**Architecture:** 后端保持 `CcdiIntermediaryController + CcdiIntermediaryServiceImpl + ccdi_biz_intermediary/ccdi_intermediary_enterprise_relation` 的现有主线，不新增平行模块。外部 API 继续保持 `bizId` 契约，服务层内部把亲属链路统一转换为“本人证件号码”处理；导入链路对齐员工数据导入，拆分为“中介信息导入”和“中介实体关联关系导入”两套独立任务与失败记录。

+## 实施任务
+
+### Task 1: 编写迁移脚本并锁定实施窗口
+
+**Files:**
+
+- Create: `sql/migration/2026-04-20-migrate-intermediary-related-num-id-to-person-id.sql`
+- Create: `sql/migration/2026-04-20-fix-ccdi-person-sub-type-dict.sql`
+- Reference: `sql/migration/2026-04-17-fix-intermediary-person-sub-type-dict.sql`
+- Reference: `sql/dpc_intermediary_dict_data_20260129.sql`
+
+- [ ] **Step 1: 写迁移前校验 SQL**
+
+在迁移脚本头部先写校验查询，明确输出：
+
+```sql
+-- 1. 找不到对应本人 biz_id 的亲属
+-- 2. 本人 person_id 为空的记录
+-- 3. 迁移后同一中介本人下 related_num_id + person_id 冲突的记录
+```
+
+- [ ] **Step 2: 写正式迁移 SQL**
+
+将旧语义统一改为新语义：
+
+```sql
+UPDATE ccdi_biz_intermediary child
+JOIN ccdi_biz_intermediary parent
+  ON child.related_num_id = parent.biz_id
+SET child.related_num_id = parent.person_id
+WHERE child.person_sub_type <> '本人';
+```
+
+- [ ] **Step 3: 写 `ccdi_person_sub_type` 字典修正脚本**
+
+至少补齐：
+
+```sql
+本人 / 配偶 / 子女 / 父母 / 兄弟姐妹 / 其他
+```
+
+Expected: 模板下拉和后端校验使用同一字典源。
+
+- [ ] **Step 4: 用 UTF-8 脚本执行 SQL 验证**
+
+Run:
+
+```bash
+bin/mysql_utf8_exec.sh sql/migration/2026-04-20-fix-ccdi-person-sub-type-dict.sql
+bin/mysql_utf8_exec.sh sql/migration/2026-04-20-migrate-intermediary-related-num-id-to-person-id.sql
+```
+
+Expected: SQL 正常执行，无乱码，无唯一性冲突。
+
+- [ ] **Step 5: 提交迁移脚本**
+
+```bash
+git add sql/migration/2026-04-20-migrate-intermediary-related-num-id-to-person-id.sql sql/migration/2026-04-20-fix-ccdi-person-sub-type-dict.sql
+git commit -m "新增中介导入迁移脚本"
+```
+
+### Task 2: 切换中介模块内部主从语义
+
+**Files:**
+
+- Modify: `ccdi-info-collection/src/main/java/com/ruoyi/info/collection/domain/CcdiBizIntermediary.java`
+- Modify: `ccdi-info-collection/src/main/java/com/ruoyi/info/collection/service/ICcdiIntermediaryService.java`

+- Test: `ccdi-info-collection/src/test/java/com/ruoyi/info/collection/mapper/CcdiIntermediaryMapperTest.java`
+
+- [ ] **Step 1: 先写失败测试，覆盖亲属新语义**
+
+补测试场景：
+
+```java
+// 1. 手工新增亲属时 related_num_id 写本人 person_id
+// 2. 查询亲属列表按 parent.person_id 关联
+// 3. 删除本人时按本人 person_id 级联删除亲属
+// 4. 相同亲属 person_id 挂到不同本人时允许成功
+```
+
+- [ ] **Step 2: 调整服务层内部转换逻辑**
+
+关键改造点：
+
+```java
+CcdiBizIntermediary owner = requireIntermediaryPerson(bizId);
+relative.setRelatedNumId(owner.getPersonId());
+```
+
+以及：
+
+```java
+wrapper.eq(CcdiBizIntermediary::getRelatedNumId, owner.getPersonId())
+```
+
+- [ ] **Step 3: 收敛唯一性校验**
+
+新增两个明确规则：
+
+```java
+// 本人：personId 全表唯一
+// 亲属：同一 relatedNumId + personId 唯一
+```
+
+Expected: 不再把亲属 `personId` 误当成全表唯一。
+
+- [ ] **Step 4: 修改联合查询 SQL**
+
+把亲属联表条件改成：
+
+```xml
+ON child.related_num_id = parent.person_id
+```
+
+Expected: 统一列表在迁移后仍能查出亲属记录。
+
+- [ ] **Step 5: 运行服务层与 Mapper 测试**
+
+Run:
+
+```bash
+mvn -pl ccdi-info-collection -am -Dtest=CcdiIntermediaryServiceImplTest,CcdiIntermediaryMapperTest test
+```
+
+Expected: 目标测试通过，新的主从语义断言成立。
+
+- [ ] **Step 6: 提交语义切换代码**
+
+```bash
+git add ccdi-info-collection/src/main/java/com/ruoyi/info/collection/domain/CcdiBizIntermediary.java ccdi-info-collection/src/main/java/com/ruoyi/info/collection/service/ICcdiIntermediaryService.java ccdi-info-collection/src/main/java/com/ruoyi/info/collection/service/impl/CcdiIntermediaryServiceImpl.java ccdi-info-collection/src/main/resources/mapper/info/collection/CcdiIntermediaryMapper.xml ccdi-info-collection/src/main/java/com/ruoyi/info/collection/domain/dto/CcdiIntermediaryRelativeAddDTO.java ccdi-info-collection/src/main/java/com/ruoyi/info/collection/domain/dto/CcdiIntermediaryRelativeEditDTO.java ccdi-info-collection/src/test/java/com/ruoyi/info/collection/service/CcdiIntermediaryServiceImplTest.java ccdi-info-collection/src/test/java/com/ruoyi/info/collection/mapper/CcdiIntermediaryMapperTest.java
+git commit -m "调整中介亲属关联语义"
+```
+
+### Task 3: 重构中介信息导入为“本人 + 亲属”混合导入

+- Test: `ccdi-info-collection/src/test/java/com/ruoyi/info/collection/controller/CcdiIntermediaryControllerTest.java`
+
+- [ ] **Step 1: 先写导入失败测试**
+
+覆盖：
+
+```java
+// 1. personSubType 使用字典下拉字段
+// 2. personSubType=本人 且 relatedNumId 非空 -> 失败
+// 3. personSubType!=本人 且 relatedNumId 为空 -> 失败
+// 4. 亲属引用本次导入前面成功的本人 -> 成功
+// 5. 同一亲属挂不同本人 -> 成功
+// 6. 同一本人名下重复亲属 -> 失败
+```
+
+- [ ] **Step 2: 调整 Excel 模板实体**
+
+最小改动：
+
+```java
+@DictDropdown(dictType = "ccdi_person_sub_type")
+private String personSubType;
+
+@ExcelProperty("关联中介本人证件号码")
+private String relatedNumId;
+```
+
+同时删除：
+
+```java
+private String relationType;
+```
+
+- [ ] **Step 3: 按“两阶段”重写导入实现**
+
+核心流程：
+
+```java
+List<CcdiIntermediaryPersonExcel> owners = ...
+List<CcdiIntermediaryPersonExcel> relatives = ...
+
+// owners: personId 全表唯一
+// relatives: relatedNumId + personId 唯一
+```
+
+Expected: 中介本人和亲属在一个文件中可混合导入。
+
+- [ ] **Step 4: 统一失败记录字段**
+
+`IntermediaryPersonImportFailureVO` 只保留当前模板字段，不再暴露废弃的 `relationType`。
+
+- [ ] **Step 5: 调整 Controller 返回文案与模板下载**
+
+Expected: 下载模板时 `personSubType` 下拉来源于 `ccdi_person_sub_type`，返回的失败记录字段与模板一致。
+
+- [ ] **Step 6: 运行导入链路测试**
+
+Run:
+
+```bash
+mvn -pl ccdi-info-collection -am -Dtest=CcdiIntermediaryPersonImportServiceImplTest,CcdiIntermediaryControllerTest test
+```
+
+Expected: 混合导入与失败口径通过。
+
+- [ ] **Step 7: 提交中介信息导入改造**
+
+```bash
+git add ccdi-info-collection/src/main/java/com/ruoyi/info/collection/domain/excel/CcdiIntermediaryPersonExcel.java ccdi-info-collection/src/main/java/com/ruoyi/info/collection/domain/vo/IntermediaryPersonImportFailureVO.java ccdi-info-collection/src/main/java/com/ruoyi/info/collection/service/ICcdiIntermediaryPersonImportService.java ccdi-info-collection/src/main/java/com/ruoyi/info/collection/service/impl/CcdiIntermediaryPersonImportServiceImpl.java ccdi-info-collection/src/main/java/com/ruoyi/info/collection/controller/CcdiIntermediaryController.java ccdi-info-collection/src/test/java/com/ruoyi/info/collection/service/CcdiIntermediaryPersonImportServiceImplTest.java ccdi-info-collection/src/test/java/com/ruoyi/info/collection/controller/CcdiIntermediaryControllerTest.java

+// 2. socialCreditCode 不存在于机构表 -> 失败
+// 3. 同一文件内相同 personId + socialCreditCode -> 失败
+// 4. 数据库内已存在相同 intermediary_biz_id + socialCredit_code -> 失败
+// 5. 正常导入成功并写入关系表

+
+- [ ] **Step 2: 新建 Excel 与失败记录对象**
+
+字段固定为：
+
+```java
+ownerPersonId

+# 中介库导入改造前端实施计划
+
+> **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.
+> **执行约束：** 仓库约定不开 subagent，执行时使用 `superpowers:executing-plans`；前端 Node 版本必须通过 `nvm` 切换到仓库已验证版本。
+
+**Goal:** 将中介库前端导入入口改造为“导入中介信息 + 导入中介实体关联关系”两按钮模式，去掉旧的“个人/机构”切换导入，打通异步轮询、失败记录查看、历史任务恢复，并保持现有手工维护链路继续使用 `bizId` 契约。
+
+**Architecture:** 保留 `ruoyi-ui/src/views/ccdiIntermediary/` 作为唯一页面入口，不新增平行页面。导入弹窗继续复用现有 `ImportDialog.vue` 外壳，但改为由父页面通过 `scene`/`importType` 驱动，而不是弹窗内部单选切换；`index.vue` 负责管理两类导入任务状态、失败记录和按钮展示，交互整体对齐员工数据导入页面。

+
+**依赖参考**
+
+- `ruoyi-ui/src/views/ccdiBaseStaff/index.vue`
+  参考顶部导入按钮、轮询、失败记录、历史任务恢复。
+- `ruoyi-ui/src/views/ccdiIntermediary/components/ImportDialog.vue`
+  继续作为导入弹窗壳子，不重复造一个全新组件。
+- `ruoyi-ui/tests/unit/employee-asset-import-ui.test.js`
+  参考导入类单测结构和断言风格。
+
+## 实施任务
+
+### Task 1: 改造 API 文件为两类导入链路
+
+**Files:**
+
+- Modify: `ruoyi-ui/src/api/ccdiIntermediary.js`
+- Test: `ruoyi-ui/tests/unit/intermediary-import-api.test.js`
+
+- [ ] **Step 1: 先写失败测试，固定 API 方法名与路径**
+
+覆盖：
+
+```js
+importPersonTemplate
+importPersonData
+getPersonImportStatus
+getPersonImportFailures
+importEnterpriseRelationTemplate
+importEnterpriseRelationData
+getEnterpriseRelationImportStatus
+getEnterpriseRelationImportFailures
+```
+
+- [ ] **Step 2: 保留中介信息导入 API**
+
+中介信息导入继续使用：
+
+```js
+/ccdi/intermediary/importPersonTemplate
+/ccdi/intermediary/importPersonData
+/ccdi/intermediary/importPersonStatus/{taskId}
+/ccdi/intermediary/importPersonFailures/{taskId}
+```
+
+- [ ] **Step 3: 新增实体关联关系导入 API**
+
+新增：
+
+```js
+/ccdi/intermediary/importEnterpriseRelationTemplate
+/ccdi/intermediary/importEnterpriseRelationData
+/ccdi/intermediary/importEnterpriseRelationStatus/{taskId}
+/ccdi/intermediary/importEnterpriseRelationFailures/{taskId}
+```
+
+- [ ] **Step 4: 删除前端对旧 `importEntity*` 导入接口的依赖**
+
+Expected: 页面不再调用旧“机构中介导入”接口。
+
+- [ ] **Step 5: 运行 API 测试**
+
+Run:
+
+```bash
+cd /Users/wkc/Desktop/ccdi/ccdi/ruoyi-ui
+node tests/unit/intermediary-import-api.test.js
+```
+
+Expected: PASS，方法名和 URL 与设计文档一致。
+
+- [ ] **Step 6: 提交 API 调整**
+
+```bash
+git add ruoyi-ui/src/api/ccdiIntermediary.js ruoyi-ui/tests/unit/intermediary-import-api.test.js
+git commit -m "调整中介导入前端接口"
+```
+
+### Task 2: 将导入弹窗改为场景驱动
+
+**Files:**
+
+- Modify: `ruoyi-ui/src/views/ccdiIntermediary/components/ImportDialog.vue`
+- Test: `ruoyi-ui/tests/unit/intermediary-import-dialog.test.js`
+
+- [ ] **Step 1: 先写弹窗行为测试**
+
+覆盖：
+
+```js
+// 1. 不再渲染“个人中介/机构中介”单选
+// 2. scene=person 时调用中介信息导入地址
+// 3. scene=enterpriseRelation 时调用实体关联关系导入地址
+// 4. 模板文案随场景切换
+```
+
+- [ ] **Step 2: 把内部单选切换改成父组件传参**
+
+新增 props：
+
+```js
+scene: {
+  type: String,
+  default: 'person'
+}
+```
+
+Expected: 弹窗自身不再维护 `formData.importType`。
+
+- [ ] **Step 3: 根据 `scene` 计算上传地址和模板地址**
+
+```js
+scene === 'person'
+scene === 'enterpriseRelation'
+```
+
+- [ ] **Step 4: 按场景返回不同提示文案**
+
+中介信息导入提示需要包含：
+
+```text
+personSubType 为字典下拉；
+本人行 relatedNumId 为空；
+亲属行 relatedNumId 填关联中介本人证件号码。
+```
+
+实体关联关系导入提示需要包含：
+
+```text
+只导入中介与机构关系；
+统一社会信用代码必须已存在于系统机构表。
+```
+
+- [ ] **Step 5: 运行弹窗测试**
+
+Run:
+
+```bash
+cd /Users/wkc/Desktop/ccdi/ccdi/ruoyi-ui
+node tests/unit/intermediary-import-dialog.test.js
+```
+
+Expected: PASS，弹窗只根据外部场景工作。
+
+- [ ] **Step 6: 提交弹窗改造**
+
+```bash
+git add ruoyi-ui/src/views/ccdiIntermediary/components/ImportDialog.vue ruoyi-ui/tests/unit/intermediary-import-dialog.test.js
+git commit -m "改造中介导入弹窗场景切换"
+```
+
+### Task 3: 改造页面顶部按钮与任务状态
+
+**Files:**
+
+- Modify: `ruoyi-ui/src/views/ccdiIntermediary/index.vue`
+- Test: `ruoyi-ui/tests/unit/intermediary-import-toolbar.test.js`
+- Test: `ruoyi-ui/tests/unit/intermediary-import-state.test.js`
+
+- [ ] **Step 1: 先写按钮与状态测试**
+
+覆盖：
+
+```js
+// 1. 顶部有两个导入按钮
+// 2. 按钮文案正确
+// 3. 两类失败记录按钮独立显示
+// 4. localStorage 使用两套独立 key
+```
+
+- [ ] **Step 2: 在工具栏增加两个导入按钮**
+
+按钮文案固定为：
+
+```vue
+导入中介信息
+导入中介实体关联关系
+```
+
+- [ ] **Step 3: 在页面中维护两套独立任务状态**
+
+建议状态结构：
+
+```js
+personImportTask
+enterpriseRelationImportTask
+```
+
+以及两套本地缓存 key：
+
+```js
+ccdi_intermediary_person_import_task
+ccdi_intermediary_enterprise_relation_import_task
+```
+
+- [ ] **Step 4: 保持页面原有手工维护链路不变**
+
+Expected: 打开详情、新增亲属、查询关系列表等既有逻辑继续走 `bizId`，不因导入改造改变页面其它交互。
+
+- [ ] **Step 5: 运行按钮与状态测试**
+
+Run:
+
+```bash
+cd /Users/wkc/Desktop/ccdi/ccdi/ruoyi-ui
+node tests/unit/intermediary-import-toolbar.test.js
+node tests/unit/intermediary-import-state.test.js
+```
+
+Expected: PASS，按钮与任务缓存隔离正确。
+
+- [ ] **Step 6: 提交页面状态改造**
+
+```bash
+git add ruoyi-ui/src/views/ccdiIntermediary/index.vue ruoyi-ui/tests/unit/intermediary-import-toolbar.test.js ruoyi-ui/tests/unit/intermediary-import-state.test.js
+git commit -m "调整中介导入页面入口状态"
+```
+
+### Task 4: 接入失败记录弹窗与完成态刷新
+
+**Files:**
+
+- Modify: `ruoyi-ui/src/views/ccdiIntermediary/index.vue`
+- Modify: `ruoyi-ui/src/views/ccdiIntermediary/components/ImportDialog.vue`
+- Modify: `ruoyi-ui/tests/unit/intermediary-person-edit-ui.test.js`
+
+- [ ] **Step 1: 先写失败记录行为断言**
+
+在现有中介页面测试里补充：
+
+```js
+// 1. 导入完成且 failureCount > 0 时显示对应失败记录按钮
+// 2. 查看失败记录时调用对应接口
+// 3. 清除历史记录后按钮消失
+```
+
+- [ ] **Step 2: 在 `index.vue` 中落两套失败记录弹窗状态**
+
+建议状态：
+
+```js
+personFailureDialogVisible
+enterpriseRelationFailureDialogVisible
+personFailureList
+enterpriseRelationFailureList
+```
+
+- [ ] **Step 3: 对齐员工导入的完成态逻辑**
+
+Expected:
+
+```js
+导入完成 -> 刷新列表 -> 刷新当前详情(如有) -> 更新失败按钮状态
+```
+
+- [ ] **Step 4: 对齐员工导入的历史记录恢复逻辑**
+
+页面刷新后如果任务仍在缓存中：
+
+```js
+恢复失败记录按钮
+恢复上次导入摘要
+必要时继续轮询
+```
+
+- [ ] **Step 5: 运行页面行为测试**
+
+Run:
+
+```bash
+cd /Users/wkc/Desktop/ccdi/ccdi/ruoyi-ui
+node tests/unit/intermediary-person-edit-ui.test.js
+```
+
+Expected: PASS，没有把导入状态逻辑打坏现有详情维护链路。
+
+- [ ] **Step 6: 提交失败记录与刷新逻辑**
+
+```bash
+git add ruoyi-ui/src/views/ccdiIntermediary/index.vue ruoyi-ui/src/views/ccdiIntermediary/components/ImportDialog.vue ruoyi-ui/tests/unit/intermediary-person-edit-ui.test.js
+git commit -m "补齐中介导入失败记录交互"
+```
+
+### Task 5: 做前端验证并回写计划结果
+
+**Files:**
+
+- Modify: `docs/plans/frontend/2026-04-20-intermediary-import-frontend-implementation.md`
+
+- [ ] **Step 1: 使用 nvm 切换到仓库已验证版本**
+
+Run:
+
+```bash
+cd /Users/wkc/Desktop/ccdi/ccdi/ruoyi-ui
+source ~/.nvm/nvm.sh && nvm use 14.21.3
+```
+
+Expected: 输出 `Now using node v14.21.3`。
+
+- [ ] **Step 2: 运行前端相关单测脚本**
+
+Run:
+
+```bash
+cd /Users/wkc/Desktop/ccdi/ccdi/ruoyi-ui
+node tests/unit/intermediary-import-api.test.js
+node tests/unit/intermediary-import-dialog.test.js
+node tests/unit/intermediary-import-toolbar.test.js
+node tests/unit/intermediary-import-state.test.js
+node tests/unit/intermediary-person-edit-ui.test.js
+```
+
+Expected: 全部 PASS。
+
+- [ ] **Step 3: 执行生产构建验证**
+
+Run:
+
+```bash
+cd /Users/wkc/Desktop/ccdi/ccdi/ruoyi-ui
+source ~/.nvm/nvm.sh && nvm use 14.21.3 && npm run build:prod
+```
+
+Expected: `BUILD SUCCESS`，没有新增语法或模块解析错误。
+
+- [ ] **Step 4: 回写执行结果**
+
+在计划文档末尾补：
+
+```markdown
+- 实际执行的 node / build 命令
+- 各测试脚本 PASS / FAIL 结果
+- 构建结果
+```
+
+- [ ] **Step 5: 提交验证结果**
+
+```bash
+git add docs/plans/frontend/2026-04-20-intermediary-import-frontend-implementation.md
+git commit -m "补充中介导入前端实施记录"
+```
+
+## 验证命令
+
+```bash
+cd /Users/wkc/Desktop/ccdi/ccdi/ruoyi-ui
+source ~/.nvm/nvm.sh && nvm use 14.21.3
+node tests/unit/intermediary-import-api.test.js
+node tests/unit/intermediary-import-dialog.test.js
+node tests/unit/intermediary-import-toolbar.test.js
+node tests/unit/intermediary-import-state.test.js
+node tests/unit/intermediary-person-edit-ui.test.js
+source ~/.nvm/nvm.sh && nvm use 14.21.3 && npm run build:prod
+```
+
+## 完成标准
+
+- 顶部只有“导入中介信息”和“导入中介实体关联关系”两个按钮
+- 导入弹窗不再内部切换“个人/机构”，而是由页面场景驱动
+- 两类导入的模板下载、上传、轮询、失败记录全部独立
+- 现有手工维护链路继续保持 `bizId` 契约
+- 页面支持恢复两类最近一次导入任务状态
+- 导入提示文案已经明确 `personSubType` 字典下拉、`relationType` 废弃、`relatedNumId` 新语义
+- 已使用 `nvm use 14.21.3` 完成前端测试脚本和生产构建验证
