Beyond the Homogeneous Approximation: Exact Linear Stability, a Structural Second-Order Source, and a Quantum-Arrival-Time Obstruction at the Robin-Boundary Signature-Change Surface

In two companion papers [1, 2] we computed the ensemble statistics of the shift in theEuclidean–Lorentzian signature-change surface of Robin-boundary quantum cosmology induced by a light stochastic spectator field, first at the homogeneous (zero-mode) level andthen, using the sep...
