+# 杜康好客 · v3.5.4 商品规格（SPU + SKU）
+
+> **2026-08-21** · mini-user / admin-web / h5-partner / API / Prisma  
+> 目标：商品详情页内可选销售规格；价格、权益、69 码、履约、上下架按 SKU；箱装按瓶当量起购与物流。
+
+## 范围
+
+| # | 项 | 交付 |
+|---|----|------|
+| 1 | 数据模型 | `common_product_item` 升级为 SPU；新增 `spec_attr` / `spec_value` / `sku` / `sku_spec`；订单快照 `sku_id` / `sale_unit` / `bottles_per_unit` |
+| 2 | 存量迁移 | 每商品 1 个默认瓶装 SKU；SQL：`prisma/migrate-product-sku-v354.sql`；脚本：`prisma/backfill-product-skus.ts` |
+| 3 | Catalog | 列表附加 `specEnabled`/`saleUnit`；详情附加 `specAttrs`/`skus`/`defaultSkuId`；旧字段拍平保留 |
+| 4 | Trade | preview/create 可选 `skuId`；无 SKU 回落 SPU；有可售 SKU 用默认/唯一 |
+| 5 | Admin | `PUT /admin/products/:id/specs`、`PUT .../skus`；商品抽屉加宽；规格弹窗填写；每规格主图 |
+| 6 | mini-user | 详情规格 chips；选规格切主图；确认页带 `skuId`；箱装数量文案 |
+| 7 | 代下单 | HQ / 合伙人可选规格 SKU |
+| 8 | 权益文案 | 「好客权益券」→「好客权益」；首页角标「享{amount}好客权益」（去掉门店 icon） |
+| 9 | SKU 码 | 系统生成 `DK` + 6 位数字，后台不可填；每规格独立 69 码 |
+| 10 | 规格主图 | `common_product_sku.image_url` 可选；空则 C 端回落商品封面 |
+
+**不做**：库存、把现有酒祖 10/15/20 合并为一个 SPU。
+
+## 兼容规则（线上）
+
+- 不改 `/api/v1` 前缀；**只增字段，不删旧字段语义**。
+- 旧客户端不传 `skuId`：
+  - 有 ≥1 个可售 SKU → 用默认（或第一个）可售 SKU
+  - **没有任何可售 SKU（未回填）→ 回落 SPU 字段，照常下单**（禁止再报「商品暂无可售规格」）
+- 传入 `skuId`（新客户端选规格）→ 按该 SKU 校验。
+- 旧 admin `PUT /admin/products/:id` 不传规格时：仅同步**唯一**默认 SKU（多规格时不同步，防误改）；不同步覆盖已生成的 DK 码。
+- SPU 上 `sku_code` / `barcode_69` 去掉唯一约束，唯一下沉到 `common_product_sku`；SPU 列保留为默认 SKU 冗余。
+- 订单 `sku_id` 可空；无规格快照走商品 69 码 / 价格。
+
+## 发版一并执行
+
+按顺序在**目标环境库**执行（先测试后生产）。本机 `npx ts-node …` 只改本地 `.env` 库，不会自动打线上。
+
+1. **规格表** `server/dukang-api/prisma/migrate-product-sku-v354.sql`  
+   建 spec/sku 表，订单加 `sku_id` / `sale_unit` / `bottles_per_unit`。
+2. **回填默认 SKU**  
+   `cd server/dukang-api && npx ts-node prisma/backfill-product-skus.ts`  
+   尚无 SKU 的商品各建 1 条默认瓶装 SKU（码用 DK）。
+3. **SKU 主图列** `server/dukang-api/prisma/migrate-sku-image.sql`  
+   ```sql
+   ALTER TABLE `common_product_sku`
+     ADD COLUMN `image_url` VARCHAR(512) NULL AFTER `sort_order`;
+   ```
+4. **SKU 码改 DK**（生产须在服务器用 `.env.production` 的 `DATABASE_URL`）  
+   `npx dotenv -e .env.production -- npx ts-node prisma/rewrite-sku-codes-dk.ts`  
+   已是 `DK`+数字的不动；`JZ-10` / `QX-001` 等会改。**不改 69 码、订单、价格。**
+5. **发票品类列**（同批次）`server/dukang-api/prisma/migrate-invoice-category.sql`  
+   ```sql
+   ALTER TABLE `user_invoice`
+     ADD COLUMN `invoice_category` VARCHAR(16) NOT NULL DEFAULT 'LIQUOR' AFTER `invoice_kind`;
+   ```
+6. 发布 API + mini-user + admin-web。  
+   **此时不要给商品加第二规格**，等新小程序上线后再配「单瓶 / 整箱」。
+
+## 起购与物流
+
+- `bottleQty = quantity × bottlesPerUnit`
+- 城市起购阈值仍是瓶；箱装 SKU（`bottlesPerUnit=6`）数量 1 即可过同城 2 / 跨城 6。
+- 大单拦截、承运商 `goodsNum` 使用瓶当量。
+
+## 关键表摘要
+
+- `common_product_spec_attr` / `common_product_spec_value`
+- `common_product_sku`（`sale_unit`=`BOTTLE|BOX`，`bottles_per_unit`，`image_url` 可选）
+- `common_product_sku_spec`
+- `user_order.sku_id` / `sale_unit` / `bottles_per_unit`
+- `user_invoice.invoice_category`：`LIQUOR` 酒水类 / `CATERING` 餐饮类；票种 C 端固定增值税普通发票
+
+## SKU 码与 69 码
+
+- SKU 码：服务端生成 `DK000001` 起，后台只展示。
+- 每个规格必须填写**互不相同**的 69 码（全局不可与其它商品 SKU 冲突）。
+- 总部「规格与 SKU」点「填写」弹窗编辑 69 码 / 价 / 履约 / 主图。
+
+## 权益与小程序 UI（同批次）
+
+| 位置 | 变更 |
+|------|------|
+| 门店详情等 | 「好客权益券」→「好客权益」 |
+| 首页商品角标 `CouponBadge` | 纯文案 **「享{amount}好客权益」**，无门店 icon |
+| 商品详情 | 规格区与「好客权益」说明之间加大间距 |
+| 待支付 / 收银台 | 顶部 logo 使用 `public/images/logo2.png`（杜康印章） |
+| 门店详情 | 「使用规则」四字红色，放在「门店详情」**上面**；门店详情正文限高，超出上下滚动 |
+| 发票申请 | 票种写死增值税普通发票；类型选酒水类/餐饮类；申请备注；抬头邮箱必填打 `*` |
+
+其它页 `BenefitFigure`（我的/权益/核销等）仍保留门店核销图标，仅首页角标去 icon。
+
+## 验收
+
+- [ ] 未配规格：旧小程序/H5/代下单路径与现网一致（无 SKU 也能下单）
+- [ ] 多规格：详情选规格后价格/权益/履约/主图变化
+- [ ] 整箱 SKU：数量 1 过起购；订单快照 `bottles_per_unit=6`
+- [ ] `GET /catalog/products/:id` 仍含 `id/name/price/spec/skuCode/...`
+- [ ] 小程序无「好客权益券」字样；首页角标为「享{金额}好客权益」且无门店 icon
+- [ ] 后台 SKU 码为 DK 开头且不可手填；每规格独立 69 码与主图
+- [ ] 门店详情「使用规则」红色且在门店详情上方；门店详情超长可滚动
+- [ ] 待支付页顶部为 logo2 印章
