Command's nature as an object-oriented replacement for callbacks, combined with its intelligence spectrum from thin (merely binding receiver to action) to fat (implementing everything internally), and its dual role bridging decoupling and state-capture, illustrates how the pattern elevates a procedural mechanism into a compositional participant capable of supporting undo, logging, and macro-composition.
Callback replacement evolving through intelligence spectrum to dual compositional role shows OO elevation pattern
