order Specification
Purpose
TBD - created by archiving change cart-checkout-orders. Update Purpose after archive.
Requirements
Requirement: Checkout splits by shop
POST /api/orders/checkout SHALL create one order per distinct shop in the cart, in a single database transaction: stock decrement, order + item insert with price snapshots, cart clear. All amounts use the cart's SKU currencies converted into the buyer-chosen display currency at checkout time.
Scenario: two shops → two orders
- WHEN the cart contains SKUs from shops A and B
- THEN two orders are created, each with only its shop's items, and the cart is empty
Scenario: insufficient stock
- WHEN any line's qty exceeds SKU stock
- THEN the whole checkout returns 409 and no order is created and stock is unchanged
Requirement: Order lifecycle
Status transitions SHALL be: pending_payment → paid → fulfilling → shipped → completed; cancellable only from pending_payment, which MUST restore stock.
Scenario: cancel restores stock
- WHEN a customer cancels a pending_payment order
- THEN stock of each SKU increases by the ordered qty and status is cancelled
Scenario: illegal transition rejected
- WHEN cancelling a paid order via the customer endpoint
- THEN the API returns 409
Requirement: Order ownership
Customers SHALL see only their own orders; shop roles only their shop's orders; platform_admin sees all.
Scenario: cross-customer read denied
- WHEN customer X requests customer Y's order id
- THEN the API returns 404
