Checkout, orders, reviews and promotions

Everything that involves money or couriers is simulated: no payment processor, no courier API, no cost.

Simulated card payments

Card number	Result
4242 4242 4242 4242 (any future expiry, any CVC)	approved
4000 0000 0000 0002	declined (PAYMENT_DECLINED, reason declined)
4000 0000 0000 9995	declined (reason: insufficient_funds)
any other valid number (Luhn)	approved

Numbers are checked (Luhn, expiry, CVC) and never stored: the payment row keeps only the brand and a simulated reference. The same cards work for promotions. The checkout page lists them with one-click fill.

Order lifecycle

PAID → (seller) ship: a courier and AWB are generated → SHIPPED → courier event delivered → DELIVERED → (buyer) confirm or automatically after 48 h (listing_rules.autoConfirmHours) → COMPLETED, payout released. Before shipping, buyer or seller can cancel: card payments are refunded and the listing is for sale again. Cash on delivery: the payment is recorded when the courier delivers.

• The listing row is locked while an order is placed: two buyers at the same moment cannot both buy it (tested).
• An accepted offer can be used at checkout (/checkout/:id?offer=…), only by the buyer it was made with.
• There is no courier integration yet, so "delivered" is triggered by the button Simulează livrarea (or the simulateDelivery mutation); both need DIAGNOSTICS_ENABLED=true. runOrderAutoConfirm runs the 48 h job now.

SMS texts are written without diacritics so they fit in one 160-character segment.

Reviews and promotions

• One review per completed order (buyer → seller). The seller's average and count are updated in one SQL statement, so existing totals (imported/demo accounts) are kept.
• Promotion packages come from platform_settings.promotion_packages; "Urcare în listă" also moves the listing to the top of "Cele mai noi"; buying the same package again extends the running one.

Tests
