Constraint Analysis of Electromagnetic Stress Asymmetry in Resonant Cavities: Upper Bounds from Emergent Vacuum Response Theory

This work presents a constraint analysis of electromagnetic stress asymmetry in asymmetric resonant cavity systems within the framework of Emergent Vacuum Response Theory (EVRT). By applying standard physical methodology based on noise-floor sensitivity, scaling relations, and representative system parameters, the study derives quantitative upper bounds on an effective stress-asymmetry response parameter. For typical tabletop resonator configurations, the effective parameter is constrained to χₑff ≲ 10⁻¹⁷, indicating that any such effect must be extremely small under current experimental conditions. The analysis does not assume the existence of anomalous forces, but instead defines the experimentally accessible parameter space and establishes a clear pathway for falsification or validation. This paper represents the constraint stage of the EVRT research program, bridging prior theoretical modeling and simulation work with experimentally testable limits.
