Object-oriented coupling management includes at least two complementary domains: boundary coupling (Adapter/Facade implementing DIP across system interfaces, enabling OCP at architectural seams) and behavioral coupling (Command/Observer/Mediator/Chain composing different communication topologies to decouple senders from receivers) — together these address coupling along both interface-boundary and sender-receiver axes in a composition-based architecture.
Structural boundary patterns and behavioral decoupling patterns partition the coupling problem space without overlap
