Cosmological Entanglement and the Holomorphic Reset: ER=EPR Structure of the Stratoverso Layer Transition

We resolve the non-locality of the cosmological reset in the Stratoverso framework by formalizing the quantum entanglement structure between the boundary layers of the cosmology (Paper L). In preceding works (Papers A–K), the transition from the terminal ground state (Layer 1) back to the high-energy initial state (Layer 140) was described as a semiclassical bounce instanton. Here, we demonstrate that this transition is the physical manifestation of geometric quantum entanglement between the two boundaries of the Riemann surface introduced in Paper J.

Applying the Maldacena–Susskind ER=EPR conjecture, we show that the Euclidean bounce instanton corresponds to a Planckian Einstein–Rosen wormhole connecting the entangled boundary sheets. We compute the holographic entanglement entropy of the boundary layers using the Ryu–Takayanagi formula in the AdS5 bulk, demonstrating that it matches the Euclidean action of the reset instanton (S_entanglement ≈ 476 k_B). We formalize the bulk as a Lindblad observer that monitors the radion field, driving wave-function decoherence and selecting the terminal state. Finally, we derive a falsifiable observational prediction: a primordial non-Gaussianity parameter f_NL ≈ 0.068 arising from the holographic entanglement channel between Layer 137 and its predecessor Layer 138, testable by CMB-S4 and future large-scale structure surveys.
