Status: OUT
The GoF's complete practitioner system — empirically validated through Lexi's demonstration of both behavioral subsystems — requires practitioners to exercise judgment in bridging between patterns, since the GoF patterns do not constitute a complete pattern language with step-by-step composition rules; the system is proven effective as a collection of related patterns but is not prescriptive about how to compose them into application architectures.
Empirical validation confirms the system works but the absence of a complete pattern language means composition requires practitioner judgment
