Emergent Infrared Coherence as Dynamic Dark Energy - EICDDE

Implementation Modules and Benchmarking Tools for Emergent Infrared Coherence as Dynamic Dark Energy (EICDDE) Cosmological model, as formally presented in the manuscript "Emergent Infrared Coherence as Dynamic Dark Energy - EICDDE.pdf". The EICDDE framework establishes a robust physical scenario wherein effective dark energy is not an unyielding cosmological constant, but rather an emergent, dynamical phenomenon. This behavior is driven by an ultralight scalar field whose active gravitational projection is regulated by open-system interactions with the surrounding cosmological bath. At high redshifts, environmental decoherence suppresses the field's coherent projection, ensuring that the model strictly preserves the precision anchors of early-universe LambdaCDM, including the primary acoustic peaks of the cosmic microwave background and Big Bang nucleosynthesis. Conversely, in the late-time Universe, a phase of gravitational recoherence gradually activates a smooth dark energy component that subtly modifies the recent expansion history. The computational resources contained herein enable the seamless integration of this coherence mechanism into standard Einstein-Boltzmann linear perturbation solvers. By tracking this dynamic closure from first principles, this framework allows researchers to break the degeneracies inherent in purely kinematic dark energy parameterizations. Consequently, it yields unambiguous, falsifiable signatures across key observational channels, including the late integrated Sachs-Wolfe effect, weak lensing, and cosmic structure growth.
