Pattern composition as a design methodology is validated through a three-tier empirical progression of increasing scope: MVC demonstrates that three patterns (Observer, Strategy, Composite) compose into a coherent architecture, Lexi demonstrates that eight patterns compose to solve seven distinct design problems at application scale, and ET++ demonstrates that nearly all 23 GoF patterns cohere within a single framework — establishing progressive empirical evidence that pattern composition scales from simple architecture through complete application design to comprehensive framework engineering.
MVC→Lexi→ET++ provides a three-tier empirical progression validating pattern composition at increasing scales of scope and complexity
