# SERVICE_MAP（服务编排总图）

## 设计原则

### 核心原则（逻辑集中化）
> **所有业务逻辑必须集中在 Service 层，禁止分散在 Controller、前端或数据库操作中。**

### 强制约束
- ✅ **所有业务必须通过 Service 层**：禁止 Controller 直接操作数据库
- ✅ **Controller 职责明确**：只负责请求/响应和权限校验
- ✅ **一个业务 = 一条 Service Flow**：每个业务操作对应一个完整的服务流程
- ✅ **服务调用必须遵循 STATE_MACHINE**：状态流转必须符合状态机定义
- ✅ **涉及收费的业务必须接入 BILLING 系统**：支付、权限、账单必须闭环
- ✅ **所有接口必须经过权限校验**：使用 `authorize()` 中间件

### 禁止行为
- ❌ **Controller 中写业务逻辑**：业务决策、状态变化、数据校验必须在 Service 层
- ❌ **前端直接写业务规则**：复杂计算、权限判断、状态流转禁止在 React 组件中实现
- ❌ **数据库操作分散**：不同模块禁止直接调用数据库，必须通过 Service 层
- ❌ **脚本或工具处理逻辑**：AI 任务或异步脚本必须通过 Service 层统一调用

### 服务层职责边界
#### Controller 层职责
- 接收 HTTP 请求和参数验证
- 调用 Service 层处理业务逻辑
- 返回响应给前端
- 权限校验（通过 `authorize()` 中间件）

#### Service 层职责（核心）
- 业务逻辑编排和状态流转
- 多模块协同和数据一致性保证
- 事务管理和异常处理
- 调用 Repository 层或外部 API

#### Repository 层职责
- 数据库 CRUD 操作
- 数据模型映射
- 查询优化
