The Fractal Logic of $Φ$-adic Recursion

We establish that valid $\Sigma_1$ propositional inference admits reduction to Fibonacci-indexed witness equations. Specifically, modus ponens verification reduces to solving a linear Diophantine equation in $O(M(\log n))$ time, where $M$ denotes integer multiplication complexity. This reduction is transitive: tautology verification proceeds via Fibonacci index arithmetic, bypassing semantic evaluation entirely. The core discovery is a transitive closure principle in $\Phi$-scaled space (Hausdorff dimension $\log_\Phi 2$), where logical consequence corresponds to a search problem over Fibonacci arcs -- a geometric invariant encoded in Zeckendorf representations. This yields a computational model wherein proof verification is achieved through \emph{arithmetic alignment} rather than truth-functional analysis, preserving soundness while respecting incompleteness. The construction synthesizes Lovelace's anticipation of symbolic computation (Note G) with the Turing-Church formalism, revealing a geometric interpretability of logic relative to a $\Sigma_1$ or $\omega$-consistent theory.
