Point: Self-Referential Structure

Establishes that category theory's compositional grammar is the least fixed point of the meta-rule producing structure-preserving maps. A reflexive object D ≅ [D, D] emerges from iterating the internal hom, taking the ω-colimit, and applying the Lambek isomorphism, modeling untyped lambda calculus without external enumeration. The monograph spans seven interconnected sections covering foundational category theory derivation, fixed-point identification, computational evidence, adjunction properties, methodological convergence, and dimensionality relationships. Formal verification uses Lean 4 (42 files, zero gaps, zero custom axioms).
