We present a constraint-based framework, rooted in the Adaptive Constraint Cascade (ACC) philosophy, in which radiation and associated momentum transfer may emerge naturally as effective consequences of fundamental physical constraints rather than as independent postulates. Starting from the Cherenkov threshold as a constraint violation, we derive a cascade: continuous energy input → violation of optical and thermodynamic constraints → radiation → momentum transfer → thrust. The framework introduces a control parameter β = nv/c and an interpolation equation for radiated power. This unified perspective connects optics, thermodynamics, and radiation pressure without invoking new physical laws, and suggests potential experimental tests using photon-dynamics systems. The framework does not propose new electrodynamics or reactionless propulsion mechanisms, but instead reinterprets known radiative and momentum-transfer processes within a constraint-based structural viewpoint.
