The restraint principle's implementation through incremental pattern adoption mechanisms (Strategy optional participation, Mediator optional abstraction) is structurally supported by the pervasive incremental-adoption infrastructure layer (noop-default and null-object meta-patterns spanning Creational, Behavioral-inheritance, and Behavioral-composition categories) — restraint is not merely a judgment heuristic but has dedicated compositional infrastructure making graceful degradation mechanically available across the entire catalog.
Restraint principle (judgment level) and incremental-adoption infrastructure (mechanism level) are two perspectives on the same design-for-partiality principle
