+ const createOrder = async (payload: Partial) => {
+ loading.value = true;
+ try {
+ const newOrder = await orderApi.createOrder(payload);
+ orders.value.push(newOrder);
+ selectedOrder.value = newOrder;
+ return newOrder;
+ } finally {
+ loading.value = false;
+ }
+ };
+
+ return {
+ orders,
+ selectedOrder,
+ loading,
+ error,
+ orderCount,
+ totalAmount,

+
+#### Step 1: OrderForm CRUD
+```powershell
+# File: src/components/composites/Order/OrderForm.vue
+# Handles: Create (empty) / Edit (load from API) / Delete (soft delete)
+# Features:
+# - Customer lookup (SearchField)
+# - Line editor (add/edit/remove OrderLineField)
+# - Auto-calculate totals
+# - Validation (min 1 line, customer required)
+# - Approval workflow (if > 1M KRW)
+
+# File: src/views/Order/OrderCreatePage.vue
+# Routes to: /admin/orders/new (pre-filled form)

+npm install -D @playwright/test
+
+# File: tests/e2e/order-crud.spec.ts
+cat > tests/e2e/order-crud.spec.ts << 'EOF'

+
+test.describe('Order CRUD', () => {
+ test('Create → Read → Edit → Delete', async ({ page }) => {
+ // 1. Login
+ await page.goto('/');
+ await page.fill('[name="email"]', 'user@example.com');
+ await page.fill('[name="password"]', 'password123!');
+ await page.click('button[type="submit"]');
+ await expect(page).toHaveURL('/admin/dashboard');
+
+ // 2. Create order
+ await page.click('a[href="/admin/orders"]');
+ await page.click('button:text("Create Order")');
+ await page.selectOption('[name="customerId"]', 'CUST-001');
+ await page.fill('[name="quantity"]', '100');
+ await page.click('button:text("Submit")');
+
+ // 3. Verify created
+ const orderNo = await page.locator('h1').textContent();
+ expect(orderNo).toMatch(/ORD-\d+/);
+
+ // 4. Edit
+ await page.click('button:text("Edit")');
+ await page.fill('[name="quantity"]', '150');
+ await page.click('button:text("Save")');
+

+ await page.click('button:text("Confirm")');
+ await expect(page).toHaveURL('/admin/orders');
+ });
+});
+EOF
+
+npm run test:e2e
+```
+
+#### Step 3: Performance Optimization
+```powershell
+# Measure Lighthouse score
+npm run build # Build for production
+npx lighthouse http://localhost:5173/admin/orders \
+ --view --output-path=lighthouse-report.html
+
+# Target: 90+ score

+# - Code split at route level
+# - Lazy-load Tabler components
+# - Tree-shake unused code
+# - Gzip + Brotli compression
+```

+
+### Component Development Guide
+
+#### Rules (Principle 1-30 Applied)
+
+1. **Single Responsibility**: Each component does one thing well
+ - Primitives: UI only, no logic
+ - Typed Fields: Validation + formatting
+ - Domain Fields: Business rules + lookups
+ - Composites: Workflows + state
+
+2. **Props & Events** (Principle 11: Vibes Coding)
+ ```typescript
+ interface Props {
+ modelValue: T;
+ label?: string;
+ disabled?: boolean;
+ errorMessage?: string;
+ }
+
+ defineEmits<{
+ 'update:modelValue': [value: T];
+ blur: [];
+ }>();
+ ```
+
+3. **Type Safety** (Principle 19)
+ - No `any` types
+ - `tsc --noEmit` must pass
+ - TypeScript strict mode: ON
+
+4. **Accessibility** (Principle 20)
+ - All inputs: `
