Abstract We present a self-consistent dynamical theory of thin-shell wormholes extended by an information-momentum flux. The vacuum is promoted to a viscoelastic medium capable of storing, transporting, and dissipating quantum information. The theory is derived from a variational principle, yielding modified junction conditions that couple geometry to the divergence of the information current. Linear stability analysis reveals information-dependent frequency shifts and damping rates, while periodic modulation generates Floquet stability islands responsible for echo-comb formation. Thermodynamic consistency is ensured by converting local information condensation into highentropy vacuum noise, preserving the second law. The information flux couples exclusively to the conformal scalar sector of metric perturbations, leaving gravitational wave speed and polarization unchanged and satisfying all current LIGO/Virgo constraints. We provide explicit estimates for all physical scales and show that the information flux can reduce exotic matter requirements. Observable signatures include echo spacing drift, frequency shifts, and anti-decoherence regimes, providing concrete experimental targets. This framework establishes the dynamical foundation for observer-decoupled measurement regimes explored in Theory-3.
