Hexagonal Architecture (Ports and Adapters), Onion Architecture, and their relationship to Clean Architecture -- enabling technology-independent domain logic with high testability. USE FOR: hexagonal architecture, ports and adapters, onion architecture, driving/driven adapters, technology-independent domain design, adapter-based testability DO NOT USE FOR: clean architecture layers specifically (use dev/craftsmanship/clean-architecture), microservice boundaries (use microservices), domain model design (use domain-driven-design)
