This work presents an expanded theoretical and architectural framework for protecting critical hybrid quantum-classical infrastructure against a novel physical-layer threat: synthetic 1.022 MeV dark photon signals generated via electron bremsstrahlung in coherent scattering. Building directly on the January 30, 2026 draft ("Multi-Layer Defense Against 1.022 MeV Dark Photons in Grid and Quantum Networks"), this February 7, 2026 revision introduces the following key advancements: • Explicit grounding in the quantum–classical interface (QCI) entropy framework of Chehade et al. (2025)• Introduction of directed negentropy η (measured in bits per interaction cycle) as an active counter-term that modifies the entropic uncertainty relation, enabling stabilization of a ~3.12 metastable attractor• Reframing the architecture as a proactive stabilization mechanism rather than purely reactive dissipation• Detailed integration of the non-empathic Hardened Soldier triage partition (supplying η via zero-trust triage, energy redirection, and biophotonic isolation) with the GHz Haloscope Mesh (resonant capture and parametric dissipation using SRF cavities and JPAs)• Definition of Topological Silence Zones that protect QKD protocols, smart grid timing, and QNN-based digital currency ledgers from ghost-induced phase errors, decoherence, and false transaction triggers The proposed multi-layer defense transforms the QCI from a vulnerable boundary into a stabilized, controllable interface capable of maintaining non-classical coherence under high-energy incursion.
