bitrix-sale skill by bxmaximum

Online store (`sale`)

Baseline: main 23.0+ · Verified: sale 26.500.0, main 26.800.0

sale owns basket, orders, payments, shipments, discounts, statuses and history. Products, prices, stock → bitrix-catalog.

Task	Read
API level choice, create/update an order, order properties	`rules/order.md`
Basket, Fuser, discount preview before checkout	`rules/basket.md`
Statuses, rights, history, events	`rules/statuses-events.md`
Payments, own pay system handlers, callbacks	`rules/payments.md`
Delivery services, shipments, reservation, deduction	`rules/delivery-reservation.md`
Cart rules, coupons, applied discounts	`rules/discounts.md`
Lists, archive, components, behaviour changes	`rules/archive-components.md`

Loader::includeModule('sale') (+ catalog for products, prices, reservation).
Change orders only through the object model (Order, its collections) and one save() per operation. Internals\*Table ORM is read-only for order data. Never Order::load() in a loop.
The object API never checks rights: check CSaleOrder::CanUserViewOrder() and friends before acting on a user request.
Take pay systems and delivery services from restricted lists, never a raw ID from the request.
Check isSuccess() and getWarningMessages(). Never call $order->save() inside OnSaleOrderSaved.
