The four sender-receiver decoupling patterns (Command, Observer, Mediator, Chain of Responsibility) address different trade-offs in binding, flexibility, and type safety. SRP's actor-based framing offers a candidate criterion for selecting among centralized coordination patterns along the Facade-Mediator spectrum, where single-actor subsystem relationships suggest Facade's simplified interface and distinct coordinated actor dependencies suggest Mediator's bidirectional control. Together, these provide practitioners with a pattern vocabulary and a candidate principled basis for choosing among decoupling and centralization topologies in a given design context.
Four decoupling patterns provide the options; SRP's actor analysis provides the selection method for topology choice
