text: Now launch Phase 5.


Task

description: Phase 5: Payments/Orders/Fulfillment

prompt:
You are implementing Phase 5 of an e-commerce platform: Payments, Orders, Fulfillment.

The project uses PHP 8.4 / Laravel 12 / Livewire v4 / SQLite / Pest v4. Working directory: /Users/fabianwesner/Herd/shop

Phases 1-4 are already complete with 206 tests passing. Phase 4 created Cart, Checkout, Discount, Shipping, Tax services. The CheckoutService.completeCheckout() method is a stub that needs to be updated to create orders.

IMPORTANT RULES:
- Use explicit PHP return types on all methods
- Use constructor property promotion
- Use PHP enums with string-backed values
- All monetary amounts are INTEGER in minor units (cents)
- Use BelongsToStore trait for store-scoped models (see app/Models/Concerns/BelongsToStore.php)
- All tests must use Pest syntax
- Run `vendor/bin/pint --dirty` before finishing
- Never use em-dash character

## 1. ENUMS TO CREATE (app/Enums/)

**OrderStatus.php**: Pending('pending'), Paid('paid'), Fulfilled('fulfilled'), Cancelled('cancelled'), Refunded('refunded')
**FinancialStatus.php**: Pending('pending'), Authorized('authorized'), Paid('paid'), PartiallyRefunded('partially_refunded'), Refunded('refunded'), Voided('voided')
**FulfillmentStatus.php**: Unfulfilled('unfulfilled'), Partial('partial'), Fulfilled('fulfilled')
**PaymentMethod.php**: CreditCard('credit_card'), Paypal('paypal'), BankTransfer('bank_transfer')
**PaymentStatus.php**: Pending('pending'), Captured('captured'), Failed('failed'), Refunded('refunded')
**RefundStatus.php**: Pending('pending'), Processed('processed'), Failed('failed')
**FulfillmentShipmentStatus.php**: Pending('pending'), Shipped('shipped'), Delivered('delivered')

## 3. MODELS

**Customer.php**: Uses BelongsToStore, HasFactory. Fillable: store_id, email, password_hash, name, marketing_opt_in. Casts: marketing_opt_in => boolean. Relationships: addresses() hasMany(CustomerAddress), orders() hasMany(Order), carts() hasMany(Cart). Implements Authenticatable (use Illuminate\Foundation\Auth\User as base class or the AuthenticatableContract with relevant traits). The getAuthPassword() method should return $this->password_hash.

**CustomerAddress.php**: HasFactory. Fillable: customer_id, label, address_json, is_default. Casts: address_json => array, is_default => boolean. Relationships: customer() belongsTo(Customer). public $timestamps = false;

**Order.php**: Uses BelongsToStore, HasFactory. Fillable: store_id, customer_id, order_number, payment_method, status, financial_status, fulfillment_status, currency, subtotal_amount, discount_amount, shipping_amount, tax_amount, total_amount, email, billing_address_json, shipping_address_json, placed_at. Casts: status => OrderStatus, financial_status => FinancialStatus, fulfillment_status => FulfillmentStatus, payment_method => PaymentMethod, billing_address_json => array, shipping_address_json => array, placed_at => datetime, all _amount fields as integer. Relationships: customer() belongsTo(Customer), lines() hasMany(OrderLine), payments() hasMany(Payment), refunds() hasMany(Refund), fulfillments() hasMany(Fulfillment).

**OrderLine.php**: HasFactory. Fillable: order_id, product_id, variant_id, title_snapshot, sku_snapshot, quantity, unit_price_amount, total_amount, tax_lines_json, discount_allocations_json. Casts: tax_lines_json => array, discount_allocations_json => array, unit_price_amount => integer, total_amount => integer, quantity => integer. Relationships: order() belongsTo(Order), product() belongsTo(Product), variant() belongsTo(ProductVariant). public $timestamps = false;

**Payment.php**: HasFactory. Fillable: order_id, provider, method, provider_payment_id, status, amount, currency, raw_json_encrypted. Casts: status => PaymentStatus, method => PaymentMethod, amount => integer. Relationships: order() belongsTo(Order), refunds() hasMany(Refund). UPDATED_AT = null (only created_at).

**Refund.php**: HasFactory. Fillable: order_id, payment_id, amount, reason, status, provider_refund_id. Casts: status => RefundStatus, amount => integer. Relationships: order() belongsTo(Order), payment() belongsTo(Payment). UPDATED_AT = null.

**Fulfillment.php**: HasFactory. Fillable: order_id, status, tracking_company, tracking_number, tracking_url, shipped_at. Casts: status => FulfillmentShipmentStatus, shipped_at => datetime. Relationships: order() belongsTo(Order), lines() hasMany(FulfillmentLine). UPDATED_AT = null.

**FulfillmentLine.php**: HasFactory. Fillable: fulfillment_id, order_line_id, quantity. Casts: quantity => integer. Relationships: fulfillment() belongsTo(Fulfillment), orderLine() belongsTo(OrderLine). public $timestamps = false;

## 4. FACTORIES

Create factories for ALL models above with sensible defaults.

## 5. CONTRACTS AND PAYMENT PROVIDER

**app/Contracts/PaymentProvider.php**: Interface with methods:
- charge(Checkout $checkout, PaymentMethod $method, array $details): PaymentResult
- refund(Payment $payment, int $amount): RefundResult

**app/ValueObjects/PaymentResult.php**: Readonly class: bool $success, string $status ('captured'|'pending'|'failed'), ?string $errorCode, string $providerPaymentId, ?array $rawResponse.

**app/ValueObjects/RefundResult.php**: Readonly class: bool $success, string $status, string $providerRefundId, ?array $rawResponse.

**app/Services/Payments/MockPaymentProvider.php**: Implements PaymentProvider.
- charge(): For credit_card: check card number in $details['card_number']. Magic numbers: '4242424242424242' => success/captured. '4000000000000002' => fail/card_declined. '4000000000009995' => fail/insufficient_funds. Any other 16-digit => success. For paypal: always success/captured. For bank_transfer: always success/pending. Generate provider_payment_id = 'mock_' . Str::random(16).
- refund(): Always success. Generate provider_refund_id = 'mock_ref_' . Str::random(16).

Register in AppServiceProvider: bind PaymentProvider interface to MockPaymentProvider.

## 6. SERVICES

### app/Services/OrderService.php

Methods:
- createFromCheckout(Checkout $checkout, PaymentResult $paymentResult): Order - Atomic transaction: create order with sequential number, create order lines with title_snapshot/sku_snapshot from product/variant, create payment record, handle inventory (commit for credit_card/paypal, keep reserved for bank_transfer), increment discount usage_count if applicable, mark cart as converted, mark checkout as completed. Dispatch OrderCreated event.
- generateOrderNumber(Store $store): string - Sequential: #1001, #1002, etc. Query max order_number for store, parse number, increment.
- cancel(Order $order, string $reason): void - Only if fulfillment_status is 'unfulfilled'. Release inventory. Set status=cancelled. Dispatch OrderCancelled event.

### app/Services/RefundService.php

Methods:
- create(Order $order, Payment $payment, int $amount, ?string $reason, bool $restock): Refund - Validate amount <= (payment.amount - sum of existing refunds for this payment). Call PaymentProvider.refund(). Create refund record. Update order financial_status (partially_refunded if partial, refunded if full). If restock=true, call InventoryService.restock for each order line. Dispatch OrderRefunded event.

### app/Services/FulfillmentService.php

Methods:
- create(Order $order, array $lines, ?array $tracking): Fulfillment - Fulfillment guard: throw FulfillmentGuardException if financial_status not in (paid, partially_refunded). Validate quantities don't exceed remaining unfulfilled. Create fulfillment + fulfillment_lines. Update order.fulfillment_status (partial if some lines remain, fulfilled if all done). Dispatch OrderFulfilled event if fully fulfilled.
- markAsShipped(Fulfillment $fulfillment, ?array $tracking): void - Set tracking info, status=shipped, shipped_at=now.
- markAsDelivered(Fulfillment $fulfillment): void - Set status=delivered.

### UPDATE app/Services/CheckoutService.php

Update the completeCheckout() method to:
1. Check idempotency: if order already exists for this checkout, return it
2. Call PaymentProvider.charge()
3. If payment fails, release inventory, throw PaymentFailedException
4. Call OrderService.createFromCheckout()
5. Return the order

Add dependency injection for PaymentProvider and OrderService.

## 7. EVENTS (app/Events/)

Create simple event classes (no extra logic needed):
- OrderCreated.php: public Order $order
- OrderPaid.php: public Order $order
- OrderFulfilled.php: public Order $order
- OrderCancelled.php: public Order $order
- OrderRefunded.php: public Order $order, public Refund $refund

## 8. JOBS

**app/Jobs/CancelUnpaidBankTransferOrders.php**: Finds orders where payment_method='bank_transfer' AND financial_status='pending' AND placed_at < now - 7 days. Cancels each via OrderService.cancel(). Register in routes/console.php: Schedule::job(...)->daily();

## 9. ALSO UPDATE

- **Cart model**: Add customer() belongsTo(Customer) relationship (was deferred from Phase 4)
- **Checkout model**: Add customer() belongsTo(Customer) relationship
- **tests/Pest.php**: Add actingAsCustomer() helper function

## 10. TESTS

Create ALL these test files. Use the createStoreContext() helper.

### tests/Feature/Payments/MockPaymentProviderTest.php (6 tests)
- charges credit card with success card number (4242424242424242 => success, captured)
- declines credit card with decline card number (4000000000000002 => fail, card_declined)
- returns insufficient funds for that card number (4000000000009995 => fail, insufficient_funds)
- charges PayPal successfully (always success, captured)
- creates pending payment for bank transfer (success, pending)
- generates mock reference ID (starts with 'mock_')

### tests/Feature/Payments/PaymentServiceTest.php (5 tests)
- processes credit card payment and creates order as paid
- processes PayPal payment and creates order as paid
- processes bank transfer and creates order as pending
- resolves MockPaymentProvider from container
- creates a payment record with correct method

### tests/Feature/Payments/BankTransferConfirmationTest.php (6 tests)
- admin can confirm bank transfer payment (financial_status pending -> paid, inventory committed)
- cannot confirm payment for non-bank-transfer orders
- cannot confirm already confirmed payment
- auto-cancel job cancels unpaid bank transfer orders after 7 days
- auto-cancel job does not cancel orders within 7 days
- auto-fulfills digital products on payment confirmation

### tests/Feature/Orders/OrderCreationTest.php (8 tests)
- creates an order from a completed checkout
- generates sequential order numbers per store (#1001, #1002, #1003)
- creates order lines with snapshots
- commits inventory on order creation (for credit_card/paypal)
- marks cart as converted
- dispatches OrderCreated event (use Event::fake)
- preserves order data when product is deleted (order_lines still accessible with snapshots)
- links order to customer when authenticated

### tests/Feature/Orders/RefundTest.php (7 tests)
- creates a full refund (financial_status = refunded)
- creates a partial refund (financial_status = partially_refunded)
- rejects refund exceeding payment amount
- restocks inventory when restock flag is true
- does not restock when restock flag is false
- records refund reason
- dispatches OrderRefunded event

### tests/Feature/Orders/FulfillmentTest.php (12 tests)
- creates a fulfillment for specific order lines
- updates order fulfillment status to partial
- updates order fulfillment status to fulfilled when all lines done
- adds tracking information
- transitions fulfillment from pending to shipped
- transitions fulfillment from shipped to delivered
- prevents fulfilling more than ordered quantity
- fulfillment guard blocks fulfillment when financial_status is pending
- fulfillment guard allows fulfillment when financial_status is paid
- fulfillment guard allows fulfillment when financial_status is partially_refunded
- auto-fulfills digital products on payment confirmation (create helper method in OrderService)
- dispatches OrderFulfilled event when all lines fulfilled

## EXECUTION ORDER

1. Create all enums
2. Create all migrations
3. Create all models and factories
4. Create contracts, value objects, payment provider
5. Create all services (OrderService, RefundService, FulfillmentService)
6. Update CheckoutService.completeCheckout()
7. Update Cart and Checkout models (add customer relationship)
8. Create events
9. Create jobs and register in console.php
10. Register PaymentProvider binding in AppServiceProvider
11. Update tests/Pest.php with actingAsCustomer helper
12. Create all tests
13. Run `php artisan migrate:fresh` to verify migrations
14. Run `php artisan test` to run all tests
15. Fix any failures
16. Run `vendor/bin/pint --dirty` to format

After creating everything, run the tests and fix ALL failures. Keep iterating until all tests pass.

IMPORTANT HELPER FOR TESTS: To create a complete order for testing refunds/fulfillments, you'll need a helper that:
1. Creates store context
2. Creates a product with variant and inventory
3. Creates a cart with a line
4. Creates a checkout
5. Processes through to completion (creates the order)

Consider adding a helper function createOrderContext() in the test files or tests/Pest.php that does this.

## 3. MODELS

**Customer.php**: Uses BelongsToStore, HasFactory. Fillable: store_id, email, password_hash, name, marketing_opt_in. Casts: marketing_opt_in => boolean. Relationships: addresses() hasMany(CustomerAddress), orders() hasMany(Order), carts() hasMany(Cart). Implements Authenticatable (use Illuminate\Foundation\Auth\User as base class or the AuthenticatableContract with relevant traits). The getAuthPassword() method should return $this->password_hash.

## 4. FACTORIES

Create factories for ALL models above with sensible defaults.

## 5. CONTRACTS AND PAYMENT PROVIDER

**app/Contracts/PaymentProvider.php**: Interface with methods:
- charge(Checkout $checkout, PaymentMethod $method, array $details): PaymentResult
- refund(Payment $payment, int $amount): RefundResult

**app/ValueObjects/PaymentResult.php**: Readonly class: bool $success, string $status ('captured'|'pending'|'failed'), ?string $errorCode, string $providerPaymentId, ?array $rawResponse.

**app/ValueObjects/RefundResult.php**: Readonly class: bool $success, string $status, string $providerRefundId, ?array $rawResponse.

**app/Services/Payments/MockPaymentProvider.php**: Implements PaymentProvider.
- charge(): For credit_card: check card number in $details['card_number']. Magic numbers: '4242424242424242' => success/captured. '4000000000000002' => fail/card_declined. '4000000000009995' => fail/insufficient_funds. Any other 16-digit => success. For paypal: always success/captured. For bank_transfer: always success/pending. Generate provider_payment_id = 'mock_' . Str::random(16).
- refund(): Always success. Generate provider_refund_id = 'mock_ref_' . Str::random(16).

Register in AppServiceProvider: bind PaymentProvider interface to MockPaymentProvider.

## 6. SERVICES

### app/Services/OrderService.php

Methods:
- createFromCheckout(Checkout $checkout, PaymentResult $paymentResult): Order - Atomic transaction: create order with sequential number, create order lines with title_snapshot/sku_snapshot from product/variant, create payment record, handle inventory (commit for credit_card/paypal, keep reserved for bank_transfer), increment discount usage_count if applicable, mark cart as converted, mark checkout as completed. Dispatch OrderCreated event.
- generateOrderNumber(Store $store): string - Sequential: #1001, #1002, etc. Query max order_number for store, parse number, increment.
- cancel(Order $order, string $reason): void - Only if fulfillment_status is 'unfulfilled'. Release inventory. Set status=cancelled. Dispatch OrderCancelled event.

### app/Services/RefundService.php

Methods:
- create(Order $order, Payment $payment, int $amount, ?string $reason, bool $restock): Refund - Validate amount <= (payment.amount - sum of existing refunds for this payment). Call PaymentProvider.refund(). Create refund record. Update order financial_status (partially_refunded if partial, refunded if full). If restock=true, call InventoryService.restock for each order line. Dispatch OrderRefunded event.

### app/Services/FulfillmentService.php

Methods:
- create(Order $order, array $lines, ?array $tracking): Fulfillment - Fulfillment guard: throw FulfillmentGuardException if financial_status not in (paid, partially_refunded). Validate quantities don't exceed remaining unfulfilled. Create fulfillment + fulfillment_lines. Update order.fulfillment_status (partial if some lines remain, fulfilled if all done). Dispatch OrderFulfilled event if fully fulfilled.
- markAsShipped(Fulfillment $fulfillment, ?array $tracking): void - Set tracking info, status=shipped, shipped_at=now.
- markAsDelivered(Fulfillment $fulfillment): void - Set status=delivered.

### UPDATE app/Services/CheckoutService.php

Update the completeCheckout() method to:
1. Check idempotency: if order already exists for this checkout, return it
2. Call PaymentProvider.charge()
3. If payment fails, release inventory, throw PaymentFailedException
4. Call OrderService.createFromCheckout()
5. Return the order

Add dependency injection for PaymentProvider and OrderService.

## 7. EVENTS (app/Events/)

Create simple event classes (no extra logic needed):
- OrderCreated.php: public Order $order
- OrderPaid.php: public Order $order
- OrderFulfilled.php: public Order $order
- OrderCancelled.php: public Order $order
- OrderRefunded.php: public Order $order, public Refund $refund

## 8. JOBS

**app/Jobs/CancelUnpaidBankTransferOrders.php**: Finds orders where payment_method='bank_transfer' AND financial_status='pending' AND placed_at < now - 7 days. Cancels each via OrderService.cancel(). Register in routes/console.php: Schedule::job(...)->daily();

## 9. ALSO UPDATE

- **Cart model**: Add customer() belongsTo(Customer) relationship (was deferred from Phase 4)
- **Checkout model**: Add customer() belongsTo(Customer) relationship
- **tests/Pest.php**: Add actingAsCustomer() helper function

## 10. TESTS

Create ALL these test files. Use the createStoreContext() helper.

### tests/Feature/Payments/MockPaymentProviderTest.php (6 tests)
- charges credit card with success card number (4242424242424242 => success, captured)
- declines credit card with decline card number (4000000000000002 => fail, card_declined)
- returns insufficient funds for that card number (4000000000009995 => fail, insufficient_funds)
- charges PayPal successfully (always success, captured)
- creates pending payment for bank transfer (success, pending)
- generates mock reference ID (starts with 'mock_')

### tests/Feature/Payments/PaymentServiceTest.php (5 tests)
- processes credit card payment and creates order as paid
- processes PayPal payment and creates order as paid
- processes bank transfer and creates order as pending
- resolves MockPaymentProvider from container
- creates a payment record with correct method

### tests/Feature/Payments/BankTransferConfirmationTest.php (6 tests)
- admin can confirm bank transfer payment (financial_status pending -> paid, inventory committed)
- cannot confirm payment for non-bank-transfer orders
- cannot confirm already confirmed payment
- auto-cancel job cancels unpaid bank transfer orders after 7 days
- auto-cancel job does not cancel orders within 7 days
- auto-fulfills digital products on payment confirmation

### tests/Feature/Orders/OrderCreationTest.php (8 tests)
- creates an order from a completed checkout
- generates sequential order numbers per store (#1001, #1002, #1003)
- creates order lines with snapshots
- commits inventory on order creation (for credit_card/paypal)
- marks cart as converted
- dispatches OrderCreated event (use Event::fake)
- preserves order data when product is deleted (order_lines still accessible with snapshots)
- links order to customer when authenticated

### tests/Feature/Orders/RefundTest.php (7 tests)
- creates a full refund (financial_status = refunded)
- creates a partial refund (financial_status = partially_refunded)
- rejects refund exceeding payment amount
- restocks inventory when restock flag is true
- does not restock when restock flag is false
- records refund reason
- dispatches OrderRefunded event

### tests/Feature/Orders/FulfillmentTest.php (12 tests)
- creates a fulfillment for specific order lines
- updates order fulfillment status to partial
- updates order fulfillment status to fulfilled when all lines done
- adds tracking information
- transitions fulfillment from pending to shipped
- transitions fulfillment from shipped to delivered
- prevents fulfilling more than ordered quantity
- fulfillment guard blocks fulfillment when financial_status is pending
- fulfillment guard allows fulfillment when financial_status is paid
- fulfillment guard allows fulfillment when financial_status is partially_refunded
- auto-fulfills digital products on payment confirmation (create helper method in OrderService)
- dispatches OrderFulfilled event when all lines fulfilled

## EXECUTION ORDER

1. Create all enums
2. Create all migrations
3. Create all models and factories
4. Create contracts, value objects, payment provider
5. Create all services (OrderService, RefundService, FulfillmentService)
6. Update CheckoutService.completeCheckout()
7. Update Cart and Checkout models (add customer relationship)
8. Create events
9. Create jobs and register in console.php
10. Register PaymentProvider binding in AppServiceProvider
11. Update tests/Pest.php with actingAsCustomer helper
12. Create all tests
13. Run `php artisan migrate:fresh` to verify migrations
14. Run `php artisan test` to run all tests
15. Fix any failures
16. Run `vendor/bin/pint --dirty` to format

After creating everything, run the tests and fix ALL failures. Keep iterating until all tests pass.

IMPORTANT HELPER FOR TESTS: To create a complete order for testing refunds/fulfillments, you'll need a helper that:
1. Creates store context
2. Creates a product with variant and inventory
3. Creates a cart with a line
4. Creates a checkout
5. Processes through to completion (creates the order)

Consider adding a helper function createOrderContext() in the test files or tests/Pest.php that does this.
