 3. 学生数据变更：测试学生数据的增删改
 4. 历史数据：验证历史数据保留
 
+### 3. 删除宿舍卫生检查（四表级联删除）
+
+**接口地址：** `DELETE /dormHygieneCheck/dormHygieneCheck/{ids}`
+
+**接口描述：** 删除宿舍卫生检查记录，自动级联删除四个相关表的数据
+
+**涉及表结构：**
+1. `xg_dorm_hygiene_check` - 宿舍卫生检查主表
+2. `xg_dorm_hygiene_student_score` - 学生卫生评分表
+3. `xg_hygiene_check_violation` - 卫生检查违纪关联表
+4. `xskh_discipline_record` - 学生违纪处分记录表（统一违纪表）
+
+**请求参数：**
+- `ids`: 待删除的检查记录ID，支持单个或多个，用逗号分隔
+
+**请求示例：**
+```http
+DELETE /dormHygieneCheck/dormHygieneCheck/1
+DELETE /dormHygieneCheck/dormHygieneCheck/1,2,3
+```
+
+**删除逻辑顺序：**
+1. **查询关联违纪记录** - 根据检查ID查询 `xg_hygiene_check_violation` 表
+2. **删除统一违纪记录** - 逻辑删除 `xskh_discipline_record` 表中的违纪处分记录
+3. **删除违纪关联记录** - 逻辑删除 `xg_hygiene_check_violation` 表中的关联记录
+4. **删除学生评分记录** - 逻辑删除 `xg_dorm_hygiene_student_score` 表中的评分记录
+5. **删除主检查记录** - 逻辑删除 `xg_dorm_hygiene_check` 主表记录
+
+**技术实现要点：**
+- ✅ **事务管理**: 使用 `@Transactional` 确保四表删除的原子性
+- ✅ **逻辑删除**: 所有表都使用逻辑删除（`deleted = 1`），不物理删除数据
+- ✅ **跨模块调用**: 通过反射动态调用学生考核管理模块的删除方法
+- ✅ **异常处理**: 优雅处理学生考核管理模块未启用的情况
+- ✅ **日志记录**: 详细记录每个步骤的删除过程和结果
+
+**响应格式：**
+```json
+{
+  "code": 200,
+  "msg": "删除成功",
+  "data": null
+}
+```
+
+**错误响应：**
+```json
+{
+  "code": 500,
+  "msg": "删除宿舍卫生检查记录失败: 具体错误信息",
+  "data": null
+}
+```
+
+**权限要求：**
+- 需要 `dormHygieneCheck:dormHygieneCheck:remove` 权限
+
+**注意事项：**
+1. **数据完整性**: 删除操作会级联删除所有相关数据，请谨慎操作
+2. **跨模块依赖**: 需要确保学生考核管理模块(xskh)正常运行
+3. **事务回滚**: 任何一个表删除失败都会导致整个操作回滚
+4. **日志追踪**: 所有删除操作都有详细日志记录，便于问题排查
+
+### 删除测试
+1. **正常删除**: 删除存在关联数据的检查记录
+2. **级联验证**: 验证四个表的数据都已正确删除
+3. **事务测试**: 测试删除过程中的异常回滚
+4. **权限测试**: 测试不同用户的删除权限
+5. **跨模块测试**: 测试学生考核管理模块未启用时的降级处理
