#### C. Pinia Store & API Integration

**Verify All 10 Store Modules**:
- [x] Orders (completed in Step 2)
- [ ] Inventory (template ready, needs implementation)

- [ ] Customers (TODO)
- [ ] Suppliers (TODO)
- [ ] Stock Transfers (TODO)
- [ ] GL Accounts (TODO)
- [ ] Vouchers (TODO)
- [ ] Users (TODO)
- [ ] Warehouses (TODO)

**Store Implementation Check**:
```bash
# Generate each store
npm run store:create Inventory
npm run store:create Products
npm run store:create Customers
# ... etc

# Verify all stores compile
npm run type-check
```

**API Client Verification**:
- [x] Base ApiClient class with axios setup
- [x] Request/response interceptors
- [x] OrdersApiClient (CRUD methods)
- [x] InventoryApiClient (list, get, update)

# Unit tests for each field
npm run test:unit -- --grep "TextField|DateField|CurrencyField|SelectField|StatusField"
```

**Navigation & Layout**:
- [x] App.vue (root component)
- [x] Router setup (4 routes: home, orders, inventory, products)
- [x] Navigation bar with links
- [ ] Responsive sidebar (if applicable)

#### E. Form & Validation Testing

**Test Validation Composables**:
```typescript
// Verify useValidation composable
import { createValidationRules } from '@/composables/useValidation'

const rules = createValidationRules()
// Test: required, email, minLength, maxLength, min, max, pattern, etc.
```

**Test Formatting Composables**:
```typescript
// Verify useFormatting composable
import { useFormatting } from '@/composables/useFormatting'

const fmt = useFormatting()
// Test: formatCurrency, formatDate, formatPhone, truncate, etc.
```

#### F. API Client Integration

**Test Store-to-API Flow**:
```bash
# 1. Orders flow
npm run test:integration -- orders.spec.ts

# 2. Verify MSW intercepts calls
npm run test:integration -- --reporter=verbose

# 3. Check error handling
npm run test:integration -- --grep "error|Error"
```

**E2E API Flow** (with dev server):
```bash
# Terminal 1: Start dev server
npm run dev

# Terminal 2: Run E2E tests
npm run test:e2e
```

## Rollback Plan (If Step 4 Fails)

**If tests fail**:
1. Identify failing test
2. Check commit log: `git log --oneline -n 10`
3. Review test output for root cause
4. Fix in code, re-run test
5. If unable to fix: rollback to previous step
   ```bash
   git reset --hard HEAD~1
   ```

**If build fails**:
1. Check for TypeScript errors: `npm run type-check`
2. Fix errors
3. Retry build: `npm run build`
