This paper introduces and formalizes the ghost lattice, a dual combinatorial structure emerging naturally within the Honeyverse model of discrete relational geometry. Beginning from a Planck‑scale Honeycomb Unit (HU) and iterating scale doublings, the model generates a rapidly expanding network of “ghost octahedra” that arise from adjacency relations between HUs. The total number of ghosts after k doublings follows the growth rule N_ghost (k) ∝ (2^k)−1, a direct consequence of the recursive dual‑lattice structure. At k=204, corresponding to the present cosmic scale, the model predicts approximately 10^61 ghost octahedra. This magnitude aligns with several independent physical scales: the Planck‑to‑cosmic length ratio, the linear holographic degree‑of‑freedom scale, the Λ curvature radius, and the square root of the 10^120 vacuum‑energy discrepancy associated with the cosmological constant problem. The convergence of these scales suggests that the ghost‑dominance transition in the Honeyverse is not a numerical coincidence but the shadow of a deeper geometric crossover. The paper argues that cosmic acceleration may be the macroscopic signature of this dual‑lattice transition, offering a structural interpretation of the Λ scale without invoking fine‑tuning or numerology. This work is part of The Honeyverse Project, an ongoing effort to explore discrete geometric models, dual‑lattice structures, and emergent cosmological behavior from first principles. v1
