Wave 1 of replacing the fixed-data mock adapter. The mall now selects its API adapter per domain, with catalog and currency served live while auth, cart, orders, shipments and invoices stay on fixed data. Backend: - seed the 6 x 2 x 2 category tree as reference data (migration 0005). The API exposes no category write route, so this cannot come from the seed script - filter public product listing by the category subtree with a recursive CTE, matching the mock's existing behaviour instead of exact-match - add sort=price with order=asc|desc, validated by hand so an unsupported value returns the project's ApiError 400 shape rather than axum's own rejection Mall: - replace the all-or-nothing mockApi boolean with a liveDomains list composed through a typed per-domain pick map - source home floors, the category menu, search and product detail from the catalog API; banners, promos, quick links, store card and comment/coupon content stay local display-only content - drop the brand facet and the sales/comments sorts: no backend model backs them - fix salesOf/commentCountOf, which parsed digits out of the product id and so rendered "NaN sold" for live UUID ids; they now hash the id Seed: 24 products across 4 shops, idempotent on re-run. Note: the mall defaults to a live catalog, so pnpm dev:mall now expects the API to be running; set NUXT_PUBLIC_LIVE_DOMAINS to an empty array for all-mock work.

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 # 16 个集成测试（vmall_test + Redis）
pnpm --filter @vmall/mall build # 各前端构建即类型校验
pnpm --filter @vmall/shop-admin build
pnpm --filter @vmall/admin build
openspec validate --all --strict # 规范校验
