Cognitive Formalism 5.0 The Structural Unification of Mind and Necessity

Preamble: The Completion of Structural Necessity This supplement establishes the structural integrity of Cognitive Formalism (CF). It utilizes the non-contingent foundation of the Private Cognitive Architecture (PCA) to derive a unified solution for the Metaphysics of Mind. This derivation defines the sole and sufficient structural condition for the possibility of coherent subjective experience, confirming CF as a system of structural necessity. This supplement therefore completes the structural arc of CF by extending necessity from cognition to consciousness. Its purpose is not to redefine consciousness metaphysically but to identify the minimally sufficient structural condition for its possibility.
