The extension spectrum (Decorator skin, Strategy guts, Template Method inheritance steps) and the wrapping taxonomy (Proxy access, Decorator responsibility, Strategy algorithm) together suggest that behavioral modification can be characterized along at least two axes: depth (how far into the object the modification reaches) and mechanism (wrapping vs. delegation vs. inheritance). Several GoF patterns occupy identifiable positions within this space, though the antecedents establish a richer four-dimensional model — adding decoupling topology and state capture — rather than confirming that a two-dimensional surface alone is complete.
Extension spectrum and wrapping taxonomy independently define axes that jointly specify positions for behavioral modification patterns
