Status: OUT
The GoF's classification of patterns into class-scope (inheritance, fixed at compile time) and object-scope (composition, changeable at runtime) — with the majority of patterns being object-scoped — provides independent classificatory evidence for composition's causal superiority: the catalog itself is predominantly object-scoped because runtime flexibility is where design flexibility lives.
The catalog's own scope classification (mostly object-scoped) independently confirms why composition dominates
