-## 5. 待补充验证
+## 5. 最终验证汇总
 
-- 最终定向测试汇总
-- 最终改动文件清单
-- 如有联调启动进程，记录已关闭结论
+### 5.1 Java 定向测试
+
+- 执行命令：
+
+```bash
+mvn -pl ccdi-project -am -Dsurefire.failIfNoSpecifiedTests=false \
+  -Dtest=CcdiAbnormalAccountRuleSqlMetadataTest,CcdiBankTagRuleSqlMetadataTest,CcdiBankTagServiceImplTest,CcdiProjectOverviewEmployeeResultBuilderTest \
+  test
+```
+
+- 执行结果：
+  - `Tests run: 25, Failures: 0, Errors: 0, Skipped: 0`
+  - `BUILD SUCCESS`
+
+### 5.2 端到端链路验证
+
+- 已重新执行后端打包：
+
+```bash
+mvn -pl ruoyi-admin -am package -DskipTests
+```
+
+- 已启动 `ruoyi-admin/target/ruoyi-admin.jar`，并使用测试登录接口获取 token
+- 已调用手工重建接口：
+
+```http
+POST /ccdi/project/tags/rebuild
+{
+  "projectId": 90331,
+  "modelCode": "ABNORMAL_ACCOUNT"
+}
+```
+
+- 后端执行日志确认：
+  - 异常账户模型规则数为 `2`
+  - 实际命中数为 `2`
+  - 员工风险聚合已刷新
+- 结果表校验确认：
+  - `SUDDEN_ACCOUNT_CLOSURE` 写入员工 `330101199001010001`
+  - `DORMANT_ACCOUNT_LARGE_ACTIVATION` 写入员工 `330101199001010002`
+- 员工总览聚合表校验确认：
+  - 员工 A 聚合命中 `ABNORMAL_ACCOUNT / SUDDEN_ACCOUNT_CLOSURE`
+  - 员工 B 聚合命中 `ABNORMAL_ACCOUNT / DORMANT_ACCOUNT_LARGE_ACTIVATION`
+
+### 5.3 进程关闭
+
+- 端到端验证完成后，已主动关闭本轮启动的后端 `java -jar ruoyi-admin.jar` 进程
+- 关闭日志可见 Quartz 调度器与 Druid 数据源正常释放，无残留后端进程
