Photons as Unbound Energy Modes in a Suppression-Governed Substrate

We interpret the photon within the KA framework as an unbound mode of energy propagating in a suppression-governed substrate. Energy exists in bound and unbound forms: bound energy constitutes matter and responds to suppression through inertial and measurement effects, while unbound energy propagates at a fixed substrate-defined speed. The invariance of light speed arises from the response of bound measurement systems, not from informational assumptions. Suppressionacts on both bound and unbound energy, modifying trajectories and energy states without altering propagation speed, accounting for gravitational lensing and redshift. Interference, diffraction, and entanglement are described as natural consequences of unbound energy propagation and its irreversible binding during interaction. The KA framework thus provides a unified and physically transparent description of photon phenomena without additional postulates.
