Cart with store_id, customer_id (nullable), session_id, status, currency, version (for optimistic concurrency), totals\n- `cart_items` - Items in cart with product_variant_id, quantity, unit_price, line_total\n- `discounts` - Discount codes with store_id, code, type (percentage/fixed), value, usage limits, date ranges\n- `discount_rules` - JSON-based rules for auto-applying discounts (min_amount, min_quantity, collection_ids, product_ids)\n- `shipping_zones` - Shipping zones per store with name\n- `shipping_rates` - Rates per zone (flat, weight, price-based) with min/max thresholds\n- `tax_zones` - Tax zones per store\n- `tax_rates` - Tax rates with percentage, inclusive/exclusive flag\n- `checkouts` - Checkout sessions linking to cart, with state machine (information, shipping, payment, processing, completed, abandoned)\n\n### Step 4.2: Models\nCreate Eloquent models with proper relationships, casts, and BelongsToStore trait where applicable:\n- Cart, CartItem, Discount, DiscountRule, ShippingZone, ShippingRate, TaxZone, TaxRate, Checkout\n- Create factories for each model\n- Create enums: CartStatus, DiscountType, DiscountStatus, ShippingRateType, CheckoutState\n\n### Step 4.3: Cart Service (app/Services/CartService.php)\nImplement the cart service with these methods:\n- `getOrCreateCart(Store $store, ?Customer $customer, ?string $sessionId): Cart`\n- `addItem(Cart $cart, ProductVariant $variant, int $quantity): CartItem` - with inventory availability check\n- `updateItemQuantity(CartItem $item, int $quantity): CartItem` - with optimistic locking via cart version\n- `removeItem(CartItem $item): void`\n- `applyDiscountCode(Cart $cart, string $code): Cart` - validates code, checks rules\n- `removeDiscount(Cart $cart): Cart`\n- `mergeGuestCart(Cart $guestCart, Customer $customer): Cart` - merge on login\n- `recalculateTotals(Cart $cart): Cart` - subtotal, discount, tax, shipping, total\n- Use optimistic concurrency: increment cart.version on every mutation, throw if stale\n\n### Step 4.4: Discount Service (app/Services/DiscountService.php)\n- `validateCode(Store $store, string $code): Discount` - check active, date range, usage limits\n- `calculateDiscount(Discount $discount, Cart $cart): int` - apply percentage or fixed\n- `checkRules(Discount $discount, Cart $cart): bool` - evaluate discount_rules JSON\n- `incrementUsage(Discount $discount): void`\n\n### Step 4.5: Shipping Calculator (app/Services/ShippingCalculator.php)\n- `getAvailableRates(Cart $cart, array $shippingAddress): Collection` - match zones by country/region\n- `calculateRate(ShippingRate $rate, Cart $cart): int` - flat, weight-based, or price-based\n\n### Step 4.6: Tax Calculator (app/Services/TaxCalculator.php)\n- `calculateTax(Cart $cart, array $address): int` - match zones, apply rates\n- `getTaxBreakdown(Cart $cart, array $address): array` - return per-rate breakdown\n- Support tax-inclusive and tax-exclusive pricing\n\n### Step 4.7: Pricing Engine (app/Services/PricingEngine.php)\nOrchestrates the full price calculation:\n- Takes a Cart, applies discount, calculates shipping, calculates tax\n- Returns a PriceBreakdown value object with subtotal, discount_amount, shipping_amount, tax_amount, total\n- All amounts in INTEGER minor units (cents)\n\n### Step 4.8: Checkout State Machine (app/Services/CheckoutService.php)\nImplement checkout flow with state transitions:\n- States: information -> shipping -> payment -> processing -> completed (also abandoned)\n- `createCheckout(Cart $cart): Checkout`\n- `updateInformation(Checkout $checkout, array $data): Checkout` - email, shipping/billing address\n- `selectShippingRate(Checkout $checkout, ShippingRate $rate): Checkout`\n- `transitionTo(Checkout $checkout, CheckoutState $state): Checkout` - validate allowed transitions\n- `abandonCheckout(Checkout $checkout): void`\n- Validate state transitions are valid (e.g. can't go from information directly to payment)\n\n### Step 4.9: Storefront Cart/Checkout UI (Livewire components)\nUpdate the existing storefront Livewire components:\n- Update `app/Livewire/Storefront/CartDrawer.php` - slide-out cart drawer with items, quantity adjustment, discount code, totals\n- Update `app/Livewire/Storefront/Cart/Show.php` - full cart page\n- Create `app/Livewire/Storefront/Checkout/Information.php` - email, shipping address form\n- Create `app/Livewire/Storefront/Checkout/Shipping.php` - shipping rate selection\n- Create `app/Livewire/Storefront/Checkout/Payment.php` - payment method selection (mock)\n- Create `app/Livewire/Storefront/Checkout/Complete.php` - order confirmation\n- Add checkout routes to routes/storefront.php\n\n## Testing Requirements\nWrite comprehensive Pest tests for:\n- CartService: add/update/remove items, apply discount, merge carts, optimistic concurrency\n- DiscountService: validation, calculation, rule checking\n- ShippingCalculator: zone matching, rate calculation\n- TaxCalculator: tax calculation, inclusive/exclusive\n- PricingEngine: full price breakdown\n- CheckoutService: state transitions, validation\n- Target: at least 60 new tests\n\n## Important Rules\n- Use `php artisan make:model` commands where possible (with `--no-interaction`)\n- All monetary amounts as INTEGER in minor units (cents)\n- Use BelongsToStore trait on store-scoped models\n- Use existing patterns from Phase 1-3 code for consistency\n- Run `vendor/bin/pint --dirty --format agent` before finishing\n- Run `php artisan test --compact` to verify all tests pass (both old and new)\n- DO NOT modify existing test files\n- DO NOT create any git commits\n- Read existing models, services, and tests to understand patterns before writing code\n"},"uuid":"8ad3261f-0539-4eac-bcd7-cf108158f519","timestamp":"2026-02-13T15:05:50.162Z"}

Uses magic card numbers for test scenarios. | Auto-capture on checkout (instant) |\n   952→| `paypal` | Simulates PayPal approval and immediate capture. Always succeeds (no magic numbers). | Auto-capture on checkout (instant) |\n   953→| `bank_transfer` | No charge at checkout. Order created with `financial_status = pending`. Admin manually confirms payment receipt. | Deferred - admin confirms payment |\n   954→\n   955→### 10.3 Magic Card Numbers (Credit Card Testing)\n   956→\n   957→When payment_method is `credit_card`, the mock provider inspects the card number submitted in the checkout form to determine the outcome:\n   958→\n   959→| Card Number | Outcome | PaymentResult |\n   960→|---|---|---|\n   961→| `4242 4242 4242 4242` | Success | `success = true`, status = `captured` |\n   962→| `4000 0000 0000 0002` | Decline | `success = false`, error = `card_declined` |\n   963→| `4000 0000 0000 9995` | Insufficient funds | `success = false`, error = `insufficient_funds` |\n   964→| Any other valid-looking number | Success | `success = true`, status = `captured` |\n   965→\n   966→The mock provider does **not** validate card expiry, CVC, or cardholder name.

prompt:
You are implementing Phase 4 (Cart, Checkout, Discounts, Shipping, Taxes) of an e-commerce shop system in Laravel 12 with Livewire v4, Flux UI Free v2, SQLite, and Pest v4.

## Context
- Phases 1-3 are complete (Foundation, Catalog, Themes/Storefront).
- Working directory: /Users/fabianwesner/Herd/shop
- All 128 existing tests pass.
- Read the specs before implementing: `specs/01-DATABASE-SCHEMA.md`, `specs/05-BUSINESS-LOGIC.md`, `specs/09-IMPLEMENTATION-ROADMAP.md`

## What to implement (Phase 4)

### Step 4.1: Migrations
Create migrations numbered 000300-000380 for these tables (read specs/01-DATABASE-SCHEMA.md for exact schemas):
- `carts` - Cart with store_id, customer_id (nullable), session_id, status, currency, version (for optimistic concurrency), totals
- `cart_items` - Items in cart with product_variant_id, quantity, unit_price, line_total
- `discounts` - Discount codes with store_id, code, type (percentage/fixed), value, usage limits, date ranges
- `discount_rules` - JSON-based rules for auto-applying discounts (min_amount, min_quantity, collection_ids, product_ids)
- `shipping_zones` - Shipping zones per store with name
- `shipping_rates` - Rates per zone (flat, weight, price-based) with min/max thresholds
- `tax_zones` - Tax zones per store
- `tax_rates` - Tax rates with percentage, inclusive/exclusive flag
- `checkouts` - Checkout sessions linking to cart, with state machine (information, shipping, payment, processing, completed, abandoned)

### Step 4.2: Models
Create Eloquent models with proper relationships, casts, and BelongsToStore trait where applicable:
- Cart, CartItem, Discount, DiscountRule, ShippingZone, ShippingRate, TaxZone, TaxRate, Checkout
- Create factories for each model
- Create enums: CartStatus, DiscountType, DiscountStatus, ShippingRateType, CheckoutState

### Step 4.3: Cart Service (app/Services/CartService.php)
Implement the cart service with these methods:
- `getOrCreateCart(Store $store, ?Customer $customer, ?string $sessionId): Cart`
- `addItem(Cart $cart, ProductVariant $variant, int $quantity): CartItem` - with inventory availability check
- `updateItemQuantity(CartItem $item, int $quantity): CartItem` - with optimistic locking via cart version
- `removeItem(CartItem $item): void`
- `applyDiscountCode(Cart $cart, string $code): Cart` - validates code, checks rules
- `removeDiscount(Cart $cart): Cart`
- `mergeGuestCart(Cart $guestCart, Customer $customer): Cart` - merge on login
- `recalculateTotals(Cart $cart): Cart` - subtotal, discount, tax, shipping, total
- Use optimistic concurrency: increment cart.version on every mutation, throw if stale

### Step 4.4: Discount Service (app/Services/DiscountService.php)
- `validateCode(Store $store, string $code): Discount` - check active, date range, usage limits
- `calculateDiscount(Discount $discount, Cart $cart): int` - apply percentage or fixed
- `checkRules(Discount $discount, Cart $cart): bool` - evaluate discount_rules JSON
- `incrementUsage(Discount $discount): void`

### Step 4.5: Shipping Calculator (app/Services/ShippingCalculator.php)
- `getAvailableRates(Cart $cart, array $shippingAddress): Collection` - match zones by country/region
- `calculateRate(ShippingRate $rate, Cart $cart): int` - flat, weight-based, or price-based

### Step 4.6: Tax Calculator (app/Services/TaxCalculator.php)
- `calculateTax(Cart $cart, array $address): int` - match zones, apply rates
- `getTaxBreakdown(Cart $cart, array $address): array` - return per-rate breakdown
- Support tax-inclusive and tax-exclusive pricing

### Step 4.7: Pricing Engine (app/Services/PricingEngine.php)
Orchestrates the full price calculation:
- Takes a Cart, applies discount, calculates shipping, calculates tax
- Returns a PriceBreakdown value object with subtotal, discount_amount, shipping_amount, tax_amount, total
- All amounts in INTEGER minor units (cents)

### Step 4.8: Checkout State Machine (app/Services/CheckoutService.php)
Implement checkout flow with state transitions:
- States: information -> shipping -> payment -> processing -> completed (also abandoned)
- `createCheckout(Cart $cart): Checkout`
- `updateInformation(Checkout $checkout, array $data): Checkout` - email, shipping/billing address
- `selectShippingRate(Checkout $checkout, ShippingRate $rate): Checkout`
- `transitionTo(Checkout $checkout, CheckoutState $state): Checkout` - validate allowed transitions
- `abandonCheckout(Checkout $checkout): void`
- Validate state transitions are valid (e.g. can't go from information directly to payment)

### Step 4.9: Storefront Cart/Checkout UI (Livewire components)
Update the existing storefront Livewire components:
- Update `app/Livewire/Storefront/CartDrawer.php` - slide-out cart drawer with items, quantity adjustment, discount code, totals
- Update `app/Livewire/Storefront/Cart/Show.php` - full cart page
- Create `app/Livewire/Storefront/Checkout/Information.php` - email, shipping address form
- Create `app/Livewire/Storefront/Checkout/Shipping.php` - shipping rate selection
- Create `app/Livewire/Storefront/Checkout/Payment.php` - payment method selection (mock)
- Create `app/Livewire/Storefront/Checkout/Complete.php` - order confirmation
- Add checkout routes to routes/storefront.php

## Testing Requirements
Write comprehensive Pest tests for:
- CartService: add/update/remove items, apply discount, merge carts, optimistic concurrency
- DiscountService: validation, calculation, rule checking
- ShippingCalculator: zone matching, rate calculation
- TaxCalculator: tax calculation, inclusive/exclusive
- PricingEngine: full price breakdown
- CheckoutService: state transitions, validation
- Target: at least 60 new tests

## Important Rules
- Use `php artisan make:model` commands where possible (with `--no-interaction`)
- All monetary amounts as INTEGER in minor units (cents)
- Use BelongsToStore trait on store-scoped models
- Use existing patterns from Phase 1-3 code for consistency
- Run `vendor/bin/pint --dirty --format agent` before finishing
- Run `php artisan test --compact` to verify all tests pass (both old and new)
- DO NOT modify existing test files
- DO NOT create any git commits
- Read existing models, services, and tests to understand patterns before writing code
