Addendum: Preservation of the Weak Equivalence Principle in the GEP Framework

This addendum provides the necessary theoretical mechanism—combining Quantum Dilution and the Chameleon Mechanism—to reconcile the strong intrinsic GEP coupling constant ($\kappa \approx 6 \times 10^{-10}\ \text{m}^2\text{kg}^{-1}\text{K}^{-1}$) with the stringent limits of the Weak Equivalence Principle (WPE) tests ($\eta < 2.7 \times 10^{-15}$). It postulates that GEP couples exclusively to the Wormhole Entropy ($s_{\text{WD}}$) fraction, effectively screening the field from bulk thermodynamic measurements.
