+# SERVICE_MAP（服务编排总图）
+
+## 设计原则
+- 所有业务必须通过 Service 层
+- Controller 不允许直接操作数据库
+- 一个业务 = 一条 Service Flow
+- 服务调用必须遵循 STATE_MACHINE 定义的状态流转
+- 涉及收费的业务必须接入 BILLING 系统
+- 所有接口必须经过权限校验
+
+---
+
+## 1. 功能开通闭环（收费核心）
+
+Flow:
+Frontend
+→ FeatureController.openFeature
+→ FeatureService.checkAccess
+→ PaymentService.createPayment
+→ PaymentCallbackService.confirm
+→ FeatureService.activateFeature
+→ PermissionService.grant
+→ BillingService.record
+→ Response
+
+---
+
+## 2. 多商户订单闭环
+
+Flow:
+Frontend
+→ OrderController.create
+→ OrderService.createOrder
+→ OrderService.splitByMerchant
+→ InventoryService.lockStock
+→ OrderRepository.save
+→ Response
+
+---
+
+## 3. 订单履约闭环
+
+Flow:
+OrderService.confirm
+→ ShipmentService.createShipment
+→ OrderService.updateStatus
+→ NotificationService.send
+
+---
+
+## 4. 结算闭环
+
+Flow:
+Scheduler / Manual Trigger
+→ SettlementService.calculate
+→ SettlementService.generateBill
+→ PaymentService.payout
+→ BillingService.record
+
+---
+
+## 5. 权限校验闭环（所有接口必须经过）
+
+Flow:
+Request
+→ AuthMiddleware
+→ PermissionService.check
+→ Controller
+
+---
+
+## 6. 商户管理闭环
+
+Flow:
+Frontend
+→ MerchantController.create
+→ MerchantService.register
+→ VerificationService.verify
+→ RBACService.assignRole
+→ Response
+
+---
+
+## 7. 店铺管理闭环
+
+Flow:
+Frontend
+→ StoreController.create
+→ StoreService.createStore
+→ ProductService.setupProducts
+→ InventoryService.initializeInventory
+→ Response
+
+---
+
+## 8. 商户数据与分析闭环
+
+Flow:
+Scheduler / Manual Trigger
+→ AnalyticsService.collectData
+→ ReportService.generateReport
+→ NotificationService.sendReport
+→ Response
+
+---
+
+## 9. 多商户库存同步闭环
+
+Flow:
+Merchant Portal
+→ InventoryController.sync
+→ InventorySyncService.syncMerchantInventory
+→ InventoryService.updateStock
+→ ProductService.updateProductStatus
+→ Response
+
+---
+
+## 10. 异常处理闭环
+
+Flow:
+Frontend / System
+→ ExceptionController.handle
+→ ExceptionService.process
+→ NotificationService.alert
+→ SettlementService.adjust
+→ Response
