+# OpenSpec Change: enterprise-api-plugin-store
+
+- **Change ID**: enterprise-api-plugin-store
+- **Package**: `@suaveplan/api-plugin-store`
+- **Category**: api/commerce
+- **Target path**: `api/commerce/api-plugin-store`
+- **Status**: PROPOSED
+- **Date**: 2026-04-24
+- **Reference spec**: `/mnt/s/web/suaveplan/enterprise/api-plugin-store.md`
+
+---
+
+## Summary
+
+Deliver `@suaveplan/api-plugin-store` on the genesis branch from scratch at enterprise quality. E-commerce plugin: product catalog (CRUD + variants + images), categories, inventory bridge to `@suaveplan/api-plugin-inventory`, cart (add/update/remove/clear), checkout (create order + payment intent bridge to `@suaveplan/api-plugin-payment`), order lifecycle (pending → confirmed → shipped → delivered → returned), and a basic discount/coupon engine. Routes under `/store`. Per-table SurrealQL. Typed events: `store:order:created`, `store:order:shipped`, `store:cart:abandoned`. Auth-gated write paths; public read paths for product catalog.

+# Tasks: enterprise-api-plugin-store
+
+**Change ID**: enterprise-api-plugin-store
+**Package**: `@suaveplan/api-plugin-store`
+**Target path**: `api/commerce/api-plugin-store`
+**Prerequisite packages on Verdaccio**: `@suaveplan/api`, `@suaveplan/api-shared`, `@suaveplan/api-plugin-auth`, `@suaveplan/api-plugin-database`, `@suaveplan/api-plugin-payment`, `@suaveplan/api-plugin-inventory`, `@suaveplan/events`, `@suaveplan/idempotency`, `@suaveplan/audit-logging`, `@suaveplan/rate-limiter`, `@suaveplan/error`
+
+---
+
+## 0. Pre-flight (non-negotiable)
+
+- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
+- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
+- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.
+
+## 1. Scaffold
+
+- [ ] Create `api/commerce/api-plugin-store/`; `package.json` v0.0.0; standard tooling.
+
+---
+
+## 2. Types, errors, events, schemas
+
+- [ ] Types: `Product`, `ProductVariant`, `Category`, `Cart`, `CartItem`, `Order`, `OrderItem`, `Coupon`, `StorePluginConfig` (Zod).
+- [ ] Errors: 7-code union + metadata + registration. Test + doc.
+- [ ] Events: `StoreEventMap` (store:order:created, store:order:shipped, store:order:delivered, store:cart:abandoned).
+- [ ] Zod schemas for all request/response shapes.
+
+---
+
+## 3. SurrealQL
+
+- [ ] Per-table files: `product.surql`, `variant.surql`, `category.surql`, `cart.surql`, `cart_item.surql`, `order.surql`, `order_item.surql`, `coupon.surql`. All with tenantId indexes.
+
+---
+
+## 4. Services (each `.test.ts` + `.md`)
+
+- [ ] **ProductService**: `createProduct`, `updateProduct`, `deleteProduct`, `getProduct`, `listProducts` (paginated, filterable by category/price/stock).
+- [ ] **CategoryService**: CRUD + tree operations (parent/child).
+- [ ] **CartService**: `addItem`, `updateItem`, `removeItem`, `clearCart`, `getCart`. Reserve inventory via `api-plugin-inventory` on add.
+- [ ] **OrderService**: `createOrder` (from cart + payment intent + inventory commit), `getOrder`, `listOrders`, `updateStatus`. Emit `store:order:*` events; audit-log state changes.
+- [ ] **CouponService**: `createCoupon`, `validateCoupon`, `applyCoupon`, `expireCoupon`.
+
+---
+
+## 5. Routes
+
+- [ ] Products: public `GET /store/products`, `GET /store/products/:id`; auth-gated `POST/PATCH/DELETE`.
+- [ ] Categories: public read; auth-gated write.
+- [ ] Cart: `GET/POST/PATCH/DELETE /store/cart` — `requireAuth`.
+- [ ] Checkout: `POST /store/checkout` — `requireAuth` + idempotency + rate-limit + audit.
+- [ ] Orders: `GET /store/orders`, `GET /store/orders/:id`, `PATCH /store/orders/:id/status` — `requireAuth` + audit.
+- [ ] Route `.test.ts` + `.md`.
+
+---
+
+## 6. Plugin factory + integration tests + publish
+
+- [ ] `createStorePlugin`: `definePlugin`, `dependencies: ["database", "auth"]`, `migrationsPath: "./surql"`.
+- [ ] Integration: add-to-cart → checkout → order created → status updated (real SurrealDB).
+- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/api-plugin-store` — green; 100% coverage.
+- [ ] `bun scripts/publish.ts --package @suaveplan/api-plugin-store`.
+- [ ] Archive → `openspec/archive/2026-04-24-enterprise-api-plugin-store/`.
