Status: OUT
The GoF catalog achieves design completeness by transcending its own Creational-Structural-Behavioral classification: the variation taxonomy provides comprehensive flexibility within categories, while the behavioral modification space crosses category boundaries (wrapping spectrum spans Structural Proxy/Decorator to Behavioral Strategy) — the catalog's three-part organizational structure is pedagogical scaffolding, not an architectural constraint on the design space it covers.
Completeness is achieved precisely because patterns cross the catalog's own category boundaries
