Physical protection systems are frequently justified through prescriptive controls and compliance checklists, yet such evidence does not necessarily demonstrate operational sufficiency under adaptive, scenario-dependent threats. This paper presents a scenario-oriented, mathematically explicit framework that provides a traceable path from threat classes to verifiable design requirements by formalizing sufficiency as acceptance constraints on the integrated detection–delay–response chain. A bounded scenario library is defined, each scenario is mapped to adversary and defender timelines, and sufficiency is expressed through a time-margin condition with optional chance constraints to capture uncertainty and concurrency effects. The method yields an auditable scenario matrix, a unified requirement template stated as measurable bounds on detection, validation, decision, delay, and response components, and an evidence mapping that specifies verification pathways via tests, timed drills, simulation, or hybrid approaches. The framework strengthens review defensibility by enforcing traceability from requirements to scenario constraints and enabling lifecycle revalidation as facility states and threat behaviors evolve.
