Implements, verifies, and archives the three remaining Wave 2 changes from openspec/MIGRATION-PLAN.md. - add-wallet-settlement (P3): demo recharge, guarded withdrawal freeze and one-time admin review, paginated own fund entries, idempotent per-shop weekly/monthly settlement statements with commission rate and one-time payout confirmation. - add-merchant-onboarding (P5): personal/enterprise applications with one live application per user, guarded review with mandatory rejection reason, and transactional shop + owner provisioning returning one-time credentials; mall onboarding/status pages and an admin review console. - add-membership-messaging (P7): platform member levels, append-only growth accrual on order completion with guarded one-way leveling, order/shipment/ refund system messages with unread/read state and soft deletion, plus the mall header unread badge. Backend: migrations 0019-0023, new wallet, settlement, merchant_onboarding, membership and messaging modules, event hooks in order/fulfillment/aftersale, and integration suites for each. Shared contract extended and all three frontends updated; code indexes, domain docs, backend guidelines and the migration tracker synced. Verification: cargo test -p vmall-api green twice consecutively; mall, admin and shop-admin builds pass; browser smoke on every new surface; openspec validate --all --strict green (33 passed). The three changes share the @vmall/shared contract, the mall mock adapter and per-app locale/nav files, so they are committed together to keep every commit buildable.

VMall — B2B2C 商城 MVP
前后端分离的多商户(B2B2C)商城。一个 Rust 后端,三个 Nuxt 前端,Postgres + Redis(本地 Docker 提供),OpenSpec 驱动开发。

技术要点:
- 金额:整数最小单位(minor units)+ ISO 币种码存储,禁止浮点。
rate_to_base表示"1 基准币 = N 本币",换算四舍五入(half-up)。 - 多语言:商品/店铺/分类/币种内容以 JSONB
{"en","zh"}存储;UI 文案在@vmall/sharedlocales + 各应用locales-extra.ts。 - RBAC:
platform_admin、shop_owner、shop_staff(带 shop_id 作用域)、customer;JWT(24h)。 - 下单:Redis 购物车 → 单事务结算,按店铺拆单,价格快照 + 扣库存;缺货整单 409 回滚;取消恢复库存。
- 发货单:支持部分发货(校验剩余量),状态联动 fulfilling → shipped → completed。
- 发票:每单最多一张有效发票;企业发票必填税号;商户开具生成发票号。
快速开始
前置:Docker 中的 Postgres(容器 pg18,postgres/postgres)与 Redis(容器 rdb8)已运行;Rust 1.98+、Node 22+、pnpm 10+。
# 1. 数据库(只需一次)
docker exec pg18 psql -U postgres -c "CREATE DATABASE vmall;" -c "CREATE DATABASE vmall_test;"
# 2. 安装依赖
pnpm install
# 3. 启动后端(自动执行 sqlx 迁移并播种平台管理员)
cargo run -p vmall-api
# 4. 播种演示数据(店铺、店主、4 个双语商品)
node scripts/seed-demo.mjs
# 5. 启动前端(另开终端)
pnpm dev:mall # :3000
pnpm dev:shop-admin # :3001
pnpm dev:admin # :3002

测试与校验
cargo test -p vmall-api # 29 个集成测试(vmall_test + Redis)
pnpm --filter @vmall/mall build # 打包;注意:并不做类型校验
pnpm --filter @vmall/shop-admin build
pnpm --filter @vmall/admin build
openspec validate --all --strict # 规范校验
nuxt build 不做类型校验:nuxt.config.ts 未开启 typescript.typeCheck,也未安装 vue-tsc。构建通过只说明能打包。要补上这道关:加 vue-tsc + typescript 依赖、设 typescript: { typeCheck: true },首次运行会暴露一批既有错误。在那之前,能证明页面可用的是浏览器实测,而不是构建。
商城的 mock 边界
apps/mall 通过 apps/mall/plugins/api.ts 的 liveDomains 按域选择适配器。当前真实后端域包括
catalog、currency、content、brands、shops、auth、account、cart、orders、shipments、invoices、
addresses、coupons、points、flashSales、groupBuying、favorites、aftersales、reviews、wallet、
merchantOnboarding、membership、messaging。
merchantOnboarding 是商家入驻域:只有 submitMerchantApplication 与
getMyMerchantApplications 两个方法走真实后端(admin 侧审核方法由 apps/admin 直接调用,
mall 不使用);把该域从 liveDomains 移除即回落到 apps/mall/mock/api.ts 的确定性 fixture。
membership(getMembership/listGrowthLogs)与 messaging(消息列表、已读、全部已读、删除、
未读数)同理各自独立可回滚;messaging 的未读数由页头徽标消费。
仍由页面直接读取 ~/mock/data 的能力记录在 docs/TBD-marketing.md。营销 fixture 仍由
fixed-data 适配器使用,作为每个已迁移域的回滚实现。
- fixed-data 适配器本身:
Mock API adapter规范要求它仍能服务每个域,因此它是回滚路径,删除它会破坏回滚。
