Note

Validation and limits

• Enable Order.Validation.Enable by default and validate orders in CustomerOrderService.SaveChangesAsync and payment post-process (throws on errors)
• Add Order.MaxOrderDocumentCount (default 20) and new OrderDocumentCountValidator to cap total child documents via IOperation tree
• Introduce CustomerOrderValidator (setting-aware) and PaymentInValidator; register all validators in DI

Settings, docs, and i18n

• Add MaxOrderDocumentCount and update ModuleConstants (defaults, AllSettings); remove settings dependency from payment service method-level validation
• Substantially expand README (architecture, features, configuration incl. validation settings)
• Add localization entries for the new setting across languages

Tests

• New unit tests for CustomerOrderValidator and OrderDocumentCountValidator; update service tests to inject validators and settings mocks
