## 🚀 Current Work

**Phase:** Database Schema Refinement ✅ **COMPLETED** (2025-11-03)

**Recent Work: Roles Table Refactoring**

Completed a major database schema refinement to improve code readability and performance:

- ✅ **Refactored `roles` table**: Changed Primary Key from `id` (UUID) to `code` (enum: 'private' | 'educator' | 'company')
- ✅ **Updated junction tables**: `user_roles.roleCode` and `product_role_visibility.roleCode` now reference `roles.code` directly
- ✅ **Simplified code**: Removed all UUID lookup queries for roles - direct enum usage throughout
- ✅ **Maintained functionality**: Many-to-Many relationships fully preserved
- ✅ **Migration**: Successfully applied, database reseeded with 3 roles, 3 products, 7 role assignments
- ✅ **Auto-assignment**: Confirmed that new users automatically receive `'private'` role on first login
- ✅ **Product visibility**: Verified role-based product filtering works correctly
- ✅ **Documentation**: Updated CLAUDE.md and ARCHITECTURE.md to reflect new schema

**Benefits:**
- Better readability: `roleCode: 'private'` instead of `roleId: 'uuid...'`
- Simpler code: No role lookups needed
- Better performance: Fewer joins in queries
- Type safety: Direct enum type usage

---

**Phase:** Phase 3 - Authentication ✅ **VALIDATED & COMPLETED** (2025-11-01)

**Validation Summary:**

- ✅ Login flow tested with Playwright - **SUCCESS**
- ✅ User created in database with `experimenta_id` (Cidaas sub: `97dcde33-d12e-4275-a0d5-e01cfbea37c2`)
- ✅ Email, first name, last name correctly stored in users table
- ✅ Session management functional
- ✅ Timestamps (created_at, updated_at) working
- ✅ Test credentials documented in .env.example
- ✅ Documentation updated to reflect Password Grant Flow implementation

**Implementation Note:**
Actual implementation uses **Password Grant Flow** (not Authorization Code Flow with PKCE). This was a deliberate choice for MVP simplicity. Authorization Code Flow can be added later for SSO/Social login support.

**Tasks Completed (18/18):**

- ✅ Install nuxt-auth-utils + jose
- ✅ Configure Cidaas environment variables in .env
- ✅ Add Cidaas config to nuxt.config.ts runtimeConfig
- ✅ Create Cidaas API client utility (server/utils/cidaas.ts) with `loginWithPassword()`
- ✅ Create JWT validation utility (server/utils/jwt.ts)
- ✅ Create /api/auth/login.post.ts endpoint (Password Grant)
- ✅ Create /api/auth/register.post.ts endpoint
- ✅ Create /api/auth/logout.post.ts endpoint
- ✅ Create /api/auth/me.get.ts endpoint
- ✅ Create useAuth composable (composables/useAuth.ts)
- ✅ Create LoginForm component (components/Auth/LoginForm.vue)
- ✅ Create RegisterForm component (components/Auth/RegisterForm.vue)
- ✅ Create auth page with tabs (pages/auth.vue)
- ✅ Create auth middleware (middleware/auth.ts)
- ✅ Create rate-limit middleware (server/middleware/rate-limit.ts)
- ✅ Test authentication flow end-to-end (**VALIDATED 2025-11-01**)
- ✅ Validate database user creation (**VALIDATED 2025-11-01**)
- ✅ Update documentation to reflect actual implementation

**Next Steps:**

1. **⚡ PRIORITY: Begin Phase 4 - Cart (Shopping Cart):**
   - Read `tasks/04-cart.md`
   - Create cart API endpoints (/api/cart/index, /api/cart/items)
   - Build useCart composable for state management
   - Create CartItem and CartSummary components
   - Implement cart persistence (session/database)
   - Test cart operations (add, update, remove items)

2. **⚡ PRIORITY: Then Phase 5 - Checkout (Forms & Flow):**
   - Read `tasks/05-checkout.md`
   - Create checkout schema (Zod) and CheckoutForm component
   - Implement address pre-fill from user profile
   - Add form validation (VeeValidate)
   - Test checkout flow end-to-end

## 🎉 Next Steps

1. **⚡ PRIORITY: Start Phase 4 - Cart (Shopping Cart)**
   - Read `tasks/04-cart.md` for detailed tasks
   - Create /api/cart/index.get.ts endpoint (get user's cart)
   - Create /api/cart/items.post.ts endpoint (add item to cart)
   - Create /api/cart/items/[id].patch.ts endpoint (update quantity)
   - Create /api/cart/items/[id].delete.ts endpoint (remove item)
   - Build useCart composable with cart state management
   - Create CartItem component (display item with quantity controls)
   - Create CartSummary component (total, subtotal, VAT)
   - Build cart page with responsive design
   - Implement cart persistence (session for guests, DB for authenticated users)
   - Test all cart operations
   - Optimize cart queries and add proper error handling

2. **⚡ PRIORITY: Then Phase 5 - Checkout (Forms & Flow)**
   - Read `tasks/05-checkout.md` for detailed tasks
   - Create checkout schema (Zod) with billing address validation
   - Build CheckoutForm and AddressForm components
   - Implement address pre-fill from user profile
   - Add form validation with VeeValidate
   - Test complete checkout flow

**Rationale for Priority Change:**
The shopping cart and checkout are critical features for the e-commerce flow. Implementing them early and sequentially allows us to test the complete purchase workflow (add to cart → checkout → payment) more effectively. Products can be seeded manually for testing in the MVP phase.
