Composition's scalability advantage over inheritance is supported by converging evidence across theory and practice: OCP's historical evolution from inheritance to abstraction provides theoretical validation (the OO community's own principle revision converged on composition), while Decorator's quantitative proof (n embellishments requiring 2^n subclasses vs. n+1 decorators) and Bridge's independent prevention of M×N class proliferation provide empirical validation across structural pattern categories.
Two independent double-evidence chains (theoretical+practical and structural+structural) merge into four-point convergence for composition superiority
