Abstract

This letter provides the exact physical motor and numerical evidence for the Z-Zero Protocol, an Effective Field Theory (EFT) where dark energy emerges as a thermodynamic backreaction driven by baryonic information erasure (Landauer's Principle). Utilizing the fine-structure constant (alpha ≈ 0. 007) as the fundamental holographic coupling efficiency, we demonstrate an exact background suppression of 3. 30% in structure growth (f*sigma8) at z=0 This 3. 30% suppression represents the purely linear cosmological baseline (the universal "idle engine"), while the residual observational discrepancy is attributed to non-linear environmental complexity (Gammaₑnv). The provided framework is ready for full Einstein-Boltzmann (CLASS/CAMB) integration to resolve the persistent Hubble (H0) and S8 tensions. Updated with numerical background integration results from CLASS/Python. Included, , and full evolution charts demonstrating the resolution of both and tensions.
