| SHOP_H5 | SHOP_H5 | STORE | store_account |

## 表前缀 → Module 写 OWNER

| 前缀 | 示例表 | OWNER Module |
|------|--------|--------------|
| user_ | user_user, user_order, user_benefit_coupon | iam / trade / benefit |
| store_ | store_store, store_account, store_payout | store / iam / settlement |
| partner_ | partner_partner, partner_bill | store(B) / settlement(C) |
| hq_ | hq_account | iam |
| common_ | common_product_item, common_event, common_city | catalog / common |
| log_ | log_third_party, log_user_analytics | 写入方 Module |

**无以下 V1 表**：payments、user_order_item、redeem_tokens（DB）。

## 关键跨模块调用链

**Mock/真实支付成功**

```
PayProvider → TradeService.handlePaySuccess()
  → BenefitService.grantOnOrderPaid(orderId)
  → OrderDelivery 预创建
  → common_event(ORDER_STATUS)
```

**核销确认**

```
RedeemService.confirm()
  → BenefitService.deduct(couponId)
  → SettlementService.createStorePayout(redeemRecordId)
```

## 禁止依赖（PR 拒绝）

| # | 禁止 |
|---|------|
| F1 | redeem 直写 order |
| F2 | store → trade/benefit |
| F3 | benefit → trade/redeem |
| F4 | trade → redeem |
| F5 | benefit → redeem |
| F6 | catalog → trade/settlement |
| F9 | apps import server 源码 |
