Abstract
An adversary copies your encrypted traffic today and waits for a quantum computer to decrypt it later. We show that the functional form of the HNDL compromise probability factorises into a temporal hazard, a multiplicative cryptographic-vulnerability and operational-exposure term, and a saturation denominator governed by the defense-attack intensity ratio. The resulting framework provides a structurally grounded basis for operational HNDL exposure prioritisation under partial observability.
