Furniture Service Use-Case Boundaries

Orchestration Responsibilities

• Application use cases orchestrate domain workflows.
• Use cases depend on DAL-facing ports, not persistence implementations.
• Use cases consume BuildingBlock capability contracts through adapter and port boundaries.
• Transport handlers map to use-case contracts and do not own orchestration logic.

Current Skeleton

• IGetFurnitureAvailabilityUseCase: orchestration boundary contract.
• GetFurnitureAvailabilityUseCase: orchestration implementation.
• IFurnitureAvailabilityContractAdapter: maps service contracts to inventory and catalog contracts.
• ICatalogProductReadPort: catalog capability read boundary.
• IFurnitureAvailabilityReadPort: inventory capability read boundary.
• IFurnitureAvailabilityGrpcContractAdapter: gRPC translation boundary for service contracts.
