Status: OUT
The GoF design system is reliably applicable in practice: its self-coherence ensures internally consistent guidance, and its practical-theoretical completeness ensures every design scenario is covered — provided practitioners avoid the DIP overgeneralization pitfall, which would undermine the composition grounding that makes the entire system work.
Theoretical coherence and completeness yield practical reliability only when composition grounding remains sound
