-- [ ] 使用 `python-dotenv` 管理环境变量
-- [ ] 生产环境与测试环境配置分离
-- [ ] 敏感信息（密码、密钥）使用环境变量而非硬编码
-
-### 2. 部署脚本化
-- [ ] 编写自动化部署脚本 (deploy.sh)
-- [ ] 包含数据库迁移步骤
-- [ ] 部署前自动备份
-
-### 3. 健康检查
-- [ ] 添加后端 `/health` 端点
-- [ ] 配置监控告警
-
-### 4. 日志管理
-- [ ] 统一日志格式
-- [ ] 日志轮转配置
-- [ ] 错误日志实时告警
-
-### 5. 数据库迁移
-- [ ] 使用 Alembic 管理数据库版本
-- [ ] 编写数据迁移脚本
-- [ ] 部署前检查数据库schema是否匹配
-
-### 6. 代码质量
+- [x] 使用 `python-dotenv` 管理环境变量 → `backend/.env.example`
+- [x] Alembic 数据库迁移管理 → `backend/alembic/`
+- [x] 单元测试框架 → `backend/tests/`
+- [ ] 自动化部署脚本 (deploy.sh)
 - [ ] CI/CD 自动化测试
-- [ ] 代码审查流程
-- [ ] 部署前在测试环境验证
+- [ ] 健康检查端点
