The GoF's practitioner system (SOLID governance + cataloged patterns + judgment pipeline) receives concrete support from Lexi's demonstration that both behavioral subsystems — event-driven (Observer-based model-view synchronization) and recursive (Composite document structure with Visitor-based spelling/hyphenation) — can operate together in integrated application design, suggesting the system's dual behavioral infrastructure is practically viable within its deliberately bounded scope.
The practitioner system's theoretical completeness (governance + patterns + judgment) is independently confirmed by Lexi's empirical proof that both behavioral subsystem types function together in a real application
