Status: OUT
The GoF constitutes a unified design methodology: its system-level coherence and completeness ensure internally consistent and comprehensive guidance, while variation's transcendence of classification boundaries ensures this guidance applies fluidly across pattern categories and lifecycle phases — the methodology is not merely a catalog of patterns but a coherent whole that transcends its own organizational structure.
The depth-9 system-coherence claim establishes internal consistency; combining with classification transcendence yields the capstone insight that the GoF is a unified methodology, not just a classified collection
