We study coherent aggregates of orientation-reversed contributions to the volume operator in discrete quantum geometry. As a concrete example, we use the Loop Quantum Gravity (LQG) volume operator, which exhibits a sign-sensitive structure: certain sectors of the kinematical Hilbert space carry orientation-dependent contributions that change sign. We interpret coherent domains dominated by such configurations as Latent Geometric Regions (LGRs), and investigate whether their dynamical redistribution can account for late-time cosmic acceleration.We develop an effective description in which cosmic expansion arises from a dynamical conversion of latent geometric capacity into positive-volume-dominated configurations, mediated by domain-wall-like structures in the orientation field. An Ising-like statistical model of vertex orientations is introduced to describe the coarse-grained dynamics of LGRs, yielding modified Friedmann equations with a time-dependent contribution that behaves similarly to dark energy at the background level. We derive the associated dynamical system and identify the governing dimensionless parameters.This work applies the LGR framework, introduced separately as a conceptual proposal for pre-geometric capacity, to cosmological dynamics within LQG kinematics; the use of LQG is a mathematical convenience, not a claim of uniqueness. We emphasize throughout a strict hierarchy of assumptions, distinguishing rigorous LQG kinematics, heuristic coarse-grained extrapolations, and speculative cosmological mapping. The framework is offered as a phenomenological model to be judged by its ability to describe data, not as a derived consequence of quantum gravity.Numerical validation includes high-statistics Monte Carlo simulations (10,000 spins, 500 realisations, 31 temperatures) confirming the stability bound x < 0.5; domain-wall nucleation simulations determining the temperature-dependent barrier linking microscopic flip rates to the cosmological conversion rate Γ; and a 3D extension of the Ising orientation dynamics on a 50³ lattice confirming the phase transition and stability bound, showing the framework is not an artifact of the 2D approximation.MCMC analysis using DESI DR2 BAO (8 points) and Pantheon+ (19 bins) yields Γ₀ = 0.52 ± 0.07, x₀ = 0.49 ± 0.10, and Ωm0 = 0.37 ± 0.02, with information criteria ΔAIC = -54.26 and ΔBIC = -51.67 favoring LGR over ΛCDM on late-time data. A comparison with Planck 2018 CMB TT data yields χ² = 125.91 on 83 binned multipoles, confirming compatibility with early-universe observations, while ΛCDM provides a better fit (χ² = 65.12) as expected for a model not yet implementing a full perturbation sector. The independently derived LGR prediction wa = 0.015 lies within 0.08σ of the Planck posterior wa = 0.0282 ± 0.1697. We stress that discrepancies between binned and full observational datasets, and between LGR and ΛCDM parameter spaces, should not be read as failures of the framework or as evidence of a superior model, but as indicators of the regime of validity of an effective description resting on incommensurable foundational premises relative to ΛCDM. Scaling analysis further shows that the macroscopic latent fraction x₀ ~ 0.1 emerges statistically from microscopic sign symmetry through collective compensation between vertices.
