Visitor's complete recursive computation mechanism (dual hierarchy plus double dispatch) validates compositional monism independently of the progressive empirical evidence chain (MVC → Lexi → ET++): even the most complex behavioral capability is achieved through composition, providing a structural proof that converges with the empirical proof — two independent routes to the same conclusion about composition's necessity.
Visitor's structural proof of compositional monism provides a third independent validation route alongside progressive empirical evidence
