Status: OUT
The GoF design system exhibits both self-coherence and a strong form of completeness: its internal coherence (SOLID unifying variation management with expert judgment, the catalog transcending its own classification through mutually reinforcing organizational principles) combines with its independent completeness (spatiotemporal infrastructure plus self-grounding theoretical framework) to support the characterization of object-oriented design as a substantially closed, mature theoretical system — coherent because its parts reinforce each other, and complete in that its dual dimensions of coverage address the practical and theoretical demands of design without apparent gaps.
The two independent depth-8 achievements (coherence and completeness) jointly establish closure of the OO design system
