# Dtos

Binary-serializable DTOs for efficient SignalR communication. All marked with `[AcBinarySerializable]`.

- **`OrderDto.cs`** — Order with items, measurement status, auditing, receipt date, GenericAttributes. Computed: IsMeasured, IsComplete, MeasuringStatus, RevisorId.
- **`OrderItemDto.cs`** — Order line item with OrderItemPallet collection. Computed: NetWeight, GrossWeight, AverageWeight, AverageWeightIsValid, IsMeasured, IsAudited.
- **`ProductDto.cs`** — Product with GenericAttribute-backed properties: IsMeasurable, Tare, AverageWeight, AverageWeightTreshold, IncomingQuantity, NetWeight.
- **`StockQuantityHistoryDto.cs`** — Stock history with net weight adjustments and inconsistency detection.
- **`GenericAttributeDto.cs`** — Key-value attribute wrapper. Polymorphic: KeyGroup = owner type, EntityId = owner ID.

## Why DTOs Exist

nopCommerce entities (Order, OrderItem, Product) are extended with measurement logic via these DTOs. The DTOs add computed properties and GenericAttribute access that the raw nopCommerce entities don't have.
