A macroscopic spectral gap forces extreme multi-path mixing with a mixing time $\tau_{\mathrm{mix}} = \mathcal{O}(1)$; a random walk on an unstructured K-R poset will visit the maximal antichain in a single step, scattering its probability distribution uniformly over the $\exp(\mathcal{O}(N^2))$ available microstates. Consequently, for unstructured posets, the effective layer volume $|L_t|$ grows exponentially, mapping to an emergent topological dimension $d \to \infty$.
