Status: OUT
Pattern composition is the fundamental mechanism for scaling from individual design problems to application-level architecture — demonstrated progressively by MVC (3 patterns composing a UI architecture), Lexi (8 patterns composing a full editor), and frameworks (multiple patterns composing reusable domain designs).
Three independent depth-1 conclusions all demonstrate the same scaling principle at increasing levels of complexity
