type: thinking

thinking:
Now I have a clear picture. Let me implement the storefront cart/checkout UI. This is a significant amount of work. Let me use parallel agents to implement the different components:

1. **Agent 1**: Product Show - add to cart, quantity selector, inventory states
2. **Agent 2**: Cart Show - full cart page with items, discounts, totals
3. **Agent 3**: Checkout component and routes

But first, I need to plan the architecture:

**Product Show component:**
- Add `addToCart()` method that uses `CartService`
- Add `quantity` property
- Show inventory status (in stock, low stock, sold out, backorder)

- Update view with proper Add to Cart button

**Cart Show component:**
- Load cart from session via `CartService::getOrCreateForSession()`
- Show line items with thumbnails, quantities, remove buttons
- Quantity stepper for each line
- Discount code input
- Subtotal, discount, total
- Checkout button
- Empty state

**Checkout component:**
- Multi-step: contact -> address -> shipping -> payment -> complete
- Use `CheckoutService` for state transitions
- Order summary sidebar
- Final submission creates order

**Order Confirmation:**
- Show order details after successful checkout
- Bank transfer instructions if applicable

Let me check what's already in place...

Now I'm looking at the PaymentProvider contract to see how the mock payment service is structured.

text: Good, I now have a full understanding of the services. Let me implement the storefront cart/checkout UI using parallel agents.


Task

description: Build Product Show add-to-cart UI

prompt:
Update the Product Show Livewire component and its Blade view to add full cart functionality.

## Current state:
- Component: `/Users/fabianwesner/Herd/shop/app/Livewire/Storefront/Products/Show.php` - has selectVariant() but no addToCart
- View: `/Users/fabianwesner/Herd/shop/resources/views/livewire/storefront/products/show.blade.php` - has disabled "Add to Cart" button with placeholder

## Requirements:

### Component (`Show.php`):
1. Add `public int $quantity = 1;` property
2. Add `addToCart()` method that:
   - Gets the current store via `app('current_store')`
   - Gets or creates a cart via `CartService::getOrCreateForSession($store)`
   - Calls `CartService::addLine($cart, $this->selectedVariantId, $this->quantity)`
   - Dispatches a browser event `cart-updated` so other components can react
   - Shows a flash/success message
   - Handles InsufficientInventoryException gracefully
3. Add a computed `stockStatus` property that checks the selected variant's inventory:
   - If no inventoryItem: "In stock" (no tracking)
   - If policy = 'continue' and available <= 0: "Available on backorder"
   - If policy = 'deny' and available <= 0: "Sold out"
   - If policy = 'deny' and available < 5: "Low stock - only X left"
   - Otherwise: "In stock"
4. Add a computed `canAddToCart` property:
   - Returns false if no variant selected
   - Returns false if sold out (deny policy, available = 0)
   - Returns true otherwise
5. Mount should load `variants.inventoryItem` relation

### View (`show.blade.php`):
1. Replace disabled button with working Add to Cart:
   ```blade
   <div class="mt-8 space-y-4">
       {{-- Stock status --}}
       <p class="text-sm {{ stock color class }}">{{ $this->stockStatus }}</p>

       {{-- Quantity selector --}}
       <div class="flex items-center gap-2">
           <button wire:click="$set('quantity', Math.max(1, quantity - 1))" ...>-</button>
           <input type="number" wire:model.live="quantity" min="1" ... />
           <button wire:click="$set('quantity', quantity + 1)" ...>+</button>
       </div>

       {{-- Add to Cart button --}}
       <flux:button wire:click="addToCart" wire:loading.attr="disabled" variant="primary" class="w-full" :disabled="!$this->canAddToCart">
           {{ $this->canAddToCart ? 'Add to Cart' : 'Sold Out' }}
       </flux:button>
   </div>
   ```
2. Show success/error messages after add to cart
3. Format prices as `XX.XX EUR` (amount / 100, with EUR suffix) per the spec

### Important implementation details:
- Use `App\Services\CartService` (inject or resolve from container)
- The current store is available via `app('current_store')` in the middleware context
- CartService::addLine throws `InsufficientInventoryException` if quantity exceeds available
- Prices are stored in cents (integer) - format as `number_format($amount / 100, 2) . ' EUR'`
- Variant's inventory is accessed via `$variant->inventoryItem` (HasOne relationship)
- InventoryItem has `policy` (enum: deny/continue), `quantity_on_hand`, `quantity_reserved`, and `available()` method

### DO NOT:
- Create new files (only edit the 2 existing files)
- Change any existing test files
- Run tests (I'll handle that)

Read both files first, then make the changes.

description: Build Cart Show full page UI

prompt:
Update the Cart Show Livewire component and its Blade view to implement full cart functionality.

## Current state:
- Component: `/Users/fabianwesner/Herd/shop/app/Livewire/Storefront/Cart/Show.php` - empty skeleton, just renders view
- View: `/Users/fabianwesner/Herd/shop/resources/views/livewire/storefront/cart/show.blade.php` - shows "Your cart is empty" only

## Requirements:

### Component (`Show.php`):
1. Properties:
   - `public ?Cart $cart = null;`
   - `public string $discountCode = '';`
   - `public string $discountError = '';`
   - `public string $discountSuccess = '';`
2. `mount()`: Load cart from session via `CartService::getOrCreateForSession(app('current_store'))`
   - Load with `lines.variant.product.media, lines.variant.inventoryItem`
3. `updateQuantity(int $lineId, int $quantity)`: Call `CartService::updateLineQuantity()`, refresh cart
4. `removeLine(int $lineId)`: Call `CartService::removeLine()`, refresh cart
5. `applyDiscount()`:
   - Store discount code in session for checkout use
   - Validate via `DiscountService::validate()` with the store and cart
   - Show success/error message
6. `removeDiscount()`: Clear discount code and session
7. Computed `subtotal`: Sum of `line_subtotal_amount` across all lines
8. Computed `cartItemCount`: Sum of quantities
9. Listen for `cart-updated` browser event to refresh (use `#[On('cart-updated')]`)

### View (`show.blade.php`):
```
+--------------------------------------------------------------+
| Your Cart (X items)                                           |
+--------------------------------------------------------------+

|         Variant: SKU         [Remove]                         |
+--------------------------------------------------------------+
| [Image] Another Product     Qty [-] [1] [+]    34.99 EUR     |
|         Variant: SKU         [Remove]                         |
+--------------------------------------------------------------+
| Discount Code: [________] [Apply]                             |
| (or) Applied: WELCOME10 [Remove]                              |
+--------------------------------------------------------------+
| Subtotal:                                    84.97 EUR        |
| Discount:                                   - 8.50 EUR        |
+--------------------------------------------------------------+
|                                    [Continue Shopping] [Checkout] |
+--------------------------------------------------------------+
```

Specific view requirements:
1. If cart is empty or has no lines: show empty state with "Continue Shopping" button linking to collections
2. Line items table/list:
   - Product thumbnail (64x64, or gray placeholder if no media)
   - Product title (linked to product page)
   - Variant SKU
   - Quantity stepper (-, input, +) - wire:click to updateQuantity
   - Line total: `unit_price_amount * quantity / 100` formatted with EUR

6. Use Tailwind CSS v4 for styling, mobile-responsive
7. Use Flux UI components where available (button, input)
8. Prices formatted as `XX.XX EUR` (cents / 100)

### Important implementation details:
- Use `App\Services\CartService` and `App\Services\DiscountService` (resolve from container)
- Current store: `app('current_store')`
- CartService uses `withoutGlobalScopes()` internally
- `CartLine` has: variant_id, quantity, unit_price_amount, line_subtotal_amount, line_total_amount
- `Cart` uses `BelongsToStore` trait
- Format prices: `number_format($amount / 100, 2) . ' EUR'`
- Store discount code in session as `session()->put('discount_code', $code)` for checkout to pick up

### DO NOT:
- Create new files (only edit the 2 existing files)
- Change any existing test files
- Run tests

Read both files first, then make the changes.

description: Build Checkout + Confirmation components

prompt:
Create the Checkout and Order Confirmation Livewire components with views and routes for the storefront.

## Architecture:

### 1. Create Checkout Component: `/Users/fabianwesner/Herd/shop/app/Livewire/Storefront/Checkout/Index.php`

Multi-step checkout using a single Livewire component with step tracking.

Properties:
- `public int $step = 1;` (1=contact, 2=address, 3=shipping, 4=payment)
- `public ?Checkout $checkout = null;`
- Contact: `public string $email = '';`
- Address: `public string $firstName = '', $lastName = '', $address1 = '', $address2 = '', $city = '', $postalCode = '', $countryCode = 'DE', $phone = '';`
- Shipping: `public ?int $selectedShippingRateId = null;`
- Payment: `public string $paymentMethod = 'credit_card';`
- Credit card: `public string $cardNumber = '', $cardholderName = '', $cardExpiry = '', $cardCvc = '';`
- `public string $error = '';`
- `public array $availableShippingRates = [];`
- `public array $totals = [];`

Methods:
1. `mount()`:
   - Get cart from session via CartService::getOrCreateForSession
   - If cart empty, redirect to /cart
   - Create checkout via CheckoutService::createCheckout($cart)
   - If discount code in session, set it on checkout: `$checkout->update(['discount_code' => session('discount_code')])`
2. `submitContact()`:
   - Validate email
   - Set email on checkout, advance to step 2
3. `submitAddress()`:
   - Validate all required fields
   - Call CheckoutService::setAddress($checkout, data)
   - Load available shipping rates from ShippingCalculator::getAvailableRates($store, $address)
   - Advance to step 3
4. `submitShipping()`:
   - Validate rate selected
   - Call CheckoutService::setShippingMethod($checkout, $selectedShippingRateId)
   - Load totals from checkout->totals_json
   - Advance to step 4
5. `submitPayment()`:
   - Validate payment method and details
   - Call CheckoutService::selectPaymentMethod($checkout, $paymentMethod)
   - Call CheckoutService::completeCheckout($checkout, $paymentDetails)
   - On success: clear cart session, redirect to /checkout/confirmation/{orderNumber}
   - On PaymentFailedException: show error, stay on step 4, release inventory happens in service
6. `goToStep(int $step)`: Allow going back (only backwards)

Use Layout attribute: `#[Layout('storefront.layouts.app')]`

### 2. Create Checkout View: `/Users/fabianwesner/Herd/shop/resources/views/livewire/storefront/checkout/index.blade.php`

Layout: Two columns on desktop (60/40), single column on mobile.

Left column: Steps
- Step indicator at top: 1. Contact > 2. Shipping > 3. Delivery > 4. Payment
- Each step shown/hidden based on current step
- Step 1 (Contact): Email input, Continue button
- Step 2 (Address): First name, last name, address1, address2, city, postal code, country code, phone - all with validation errors. Continue button.
- Step 3 (Shipping): Radio buttons for each available rate showing name + price. Continue button.
- Step 4 (Payment): Radio selection for payment method (Credit Card, PayPal, Bank Transfer). Credit card fields shown when selected. "Pay Now - XX.XX EUR" button.

Right column: Order Summary (sticky)
- List of cart items with name, qty, line total
- Subtotal, Discount (if any), Shipping, Tax, Total
- All from checkout->totals_json

Error display: Show $error at top of payment step if payment fails.

Use Tailwind CSS v4, Flux UI components (button, input, radio).

### 3. Create Confirmation Component: `/Users/fabianwesner/Herd/shop/app/Livewire/Storefront/Checkout/Confirmation.php`

Properties:
- `public Order $order;`

mount(string $orderNumber):
- Find order by order_number, load lines, payments
- Abort 404 if not found

View shows:
- Green checkmark icon
- "Thank you for your order!" heading
- Order number
- "A confirmation email has been sent to {email}"
- Order items list
- Shipping address, payment method
- Totals
- If bank_transfer: Show bank details callout (Mock Bank AG, IBAN: DE89 3704 0044 0532 0130 00, BIC: COBADEFFXXX, reference: order number, 7-day deadline)
- "Continue Shopping" button

### 4. Create Confirmation View: `/Users/fabianwesner/Herd/shop/resources/views/livewire/storefront/checkout/confirmation.blade.php`

### 5. Update Routes: `/Users/fabianwesner/Herd/shop/routes/web.php`

Add these routes inside the existing storefront middleware group:
```php
Route::get('/checkout', \App\Livewire\Storefront\Checkout\Index::class)->name('checkout');
Route::get('/checkout/confirmation/{orderNumber}', \App\Livewire\Storefront\Checkout\Confirmation::class)->name('checkout.confirmation');
```

Also add the use statements at the top.

### Important implementation details:
- Use `App\Services\CheckoutService`, `App\Services\CartService`, `App\Services\ShippingCalculator`
- Current store: `app('current_store')`
- Checkout model: store_id, cart_id, customer_id, email, shipping_address_json, billing_address_json, shipping_method_id, payment_method, discount_code, totals_json, status, expires_at
- CheckoutService expects: setAddress($checkout, ['email' => ..., 'shipping_address' => ['first_name' => ..., 'last_name' => ..., 'address1' => ..., 'city' => ..., 'country_code' => ..., 'postal_code' => ...]])
- Payment details for credit card: ['card_number' => ..., 'cardholder_name' => ..., 'card_expiry' => ..., 'card_cvc' => ...]
- PaymentMethod enum values: 'credit_card', 'paypal', 'bank_transfer'
- completeCheckout returns an Order object
- PaymentFailedException is thrown on payment failure
- Order model has: order_number, email, total_amount, shipping_address_json, payment_method, lines relation
- Prices in cents, format as `number_format($amount / 100, 2) . ' EUR'`
- Order confirmation should be accessible without authentication (guest checkout)
- ShippingRate has: name, type, config_json (with 'amount' key for flat rates)

### Style notes:
- Use storefront layout `#[Layout('storefront.layouts.app')]`
- Tailwind CSS v4 classes, mobile-first responsive
- Use Flux UI button and input components where available
- Clean, professional checkout flow

Read the existing routes/web.php, CheckoutService, and relevant models before creating the files.

   - If cart empty, redirect to /cart
   - Create checkout via CheckoutService::createCheckout($cart)
   - If discount code in session, set it on checkout: `$checkout->update(['discount_code' => session('discount_code')])`
2. `submitContact()`:
   - Validate email
   - Set email on checkout, advance to step 2
3. `submitAddress()`:
   - Validate all required fields

   - Load totals from checkout->totals_json
   - Advance to step 4
5. `submitPayment()`:
   - Validate payment method and details
   - Call CheckoutService::selectPaymentMethod($checkout, $paymentMethod)
   - Call CheckoutService::completeCheckout($checkout, $paymentDetails)
   - On success: clear cart session, redirect to /checkout/confirmation/{orderNumber}
   - On PaymentFailedException: show error, stay on step 4, release inventory happens in service
6. `goToStep(int $step)`: Allow going back (only backwards)

Use Layout attribute: `#[Layout('storefront.layouts.app')]`

### 2. Create Checkout View: `/Users/fabianwesner/Herd/shop/resources/views/livewire/storefront/checkout/index.blade.php`

Layout: Two columns on desktop (60/40), single column on mobile.

Left column: Steps
- Step indicator at top: 1. Contact > 2. Shipping > 3. Delivery > 4. Payment
- Each step shown/hidden based on current step
- Step 1 (Contact): Email input, Continue button
- Step 2 (Address): First name, last name, address1, address2, city, postal code, country code, phone - all with validation errors. Continue button.
- Step 3 (Shipping): Radio buttons for each available rate showing name + price. Continue button.
- Step 4 (Payment): Radio selection for payment method (Credit Card, PayPal, Bank Transfer). Credit card fields shown when selected. "Pay Now - XX.XX EUR" button.

Right column: Order Summary (sticky)
- List of cart items with name, qty, line total
- Subtotal, Discount (if any), Shipping, Tax, Total
- All from checkout->totals_json

Error display: Show $error at top of payment step if payment fails.

Use Tailwind CSS v4, Flux UI components (button, input, radio).

### 3. Create Confirmation Component: `/Users/fabianwesner/Herd/shop/app/Livewire/Storefront/Checkout/Confirmation.php`

Properties:
- `public Order $order;`

mount(string $orderNumber):
- Find order by order_number, load lines, payments
- Abort 404 if not found

View shows:
- Green checkmark icon
- "Thank you for your order!" heading
- Order number
- "A confirmation email has been sent to {email}"
- Order items list
- Shipping address, payment method
- Totals
- If bank_transfer: Show bank details callout (Mock Bank AG, IBAN: DE89 3704 0044 0532 0130 00, BIC: COBADEFFXXX, reference: order number, 7-day deadline)
- "Continue Shopping" button

### 4. Create Confirmation View: `/Users/fabianwesner/Herd/shop/resources/views/livewire/storefront/checkout/confirmation.blade.php`

### 5. Update Routes: `/Users/fabianwesner/Herd/shop/routes/web.php`

Add these routes inside the existing storefront middleware group:
```php
Route::get('/checkout', \App\Livewire\Storefront\Checkout\Index::class)->name('checkout');
Route::get('/checkout/confirmation/{orderNumber}', \App\Livewire\Storefront\Checkout\Confirmation::class)->name('checkout.confirmation');
```

Also add the use statements at the top.

### Important implementation details:
- Use `App\Services\CheckoutService`, `App\Services\CartService`, `App\Services\ShippingCalculator`
- Current store: `app('current_store')`
- Checkout model: store_id, cart_id, customer_id, email, shipping_address_json, billing_address_json, shipping_method_id, payment_method, discount_code, totals_json, status, expires_at
- CheckoutService expects: setAddress($checkout, ['email' => ..., 'shipping_address' => ['first_name' => ..., 'last_name' => ..., 'address1' => ..., 'city' => ..., 'country_code' => ..., 'postal_code' => ...]])
- Payment details for credit card: ['card_number' => ..., 'cardholder_name' => ..., 'card_expiry' => ..., 'card_cvc' => ...]
- PaymentMethod enum values: 'credit_card', 'paypal', 'bank_transfer'
- completeCheckout returns an Order object
- PaymentFailedException is thrown on payment failure
- Order model has: order_number, email, total_amount, shipping_address_json, payment_method, lines relation
- Prices in cents, format as `number_format($amount / 100, 2) . ' EUR'`
- Order confirmation should be accessible without authentication (guest checkout)
- ShippingRate has: name, type, config_json (with 'amount' key for flat rates)

### Style notes:
- Use storefront layout `#[Layout('storefront.layouts.app')]`
- Tailwind CSS v4 classes, mobile-first responsive
- Use Flux UI button and input components where available
- Clean, professional checkout flow

Read the existing routes/web.php, CheckoutService, and relevant models before creating the files.


thinking: The agents are still working on the cart/checkout UI. Let me wait for them to complete. In the meantime, let me check on the checkout agent's progress since it's the most complex one.
