Status: OUT
The GoF's compositional monism — dual behavioral infrastructure proven to use composition as necessary substrate — achieves full operational status only while Decorator's identity breakage (decorated component not identical to original) does not propagate to invalidate the wrapping taxonomy that connects both behavioral subsystems.
Compositional monism requires that identity fragility in wrapping does not cascade across subsystems
