CSD Framework: A Structural Interpretation of Light and Wave–Particle Behavior

This work presents an updated version (9.1) of the CSD framework, introducing a refined interpretation of wave–particle behavior. Light is interpreted not as an object moving through space, but as the observable propagation of spacetime structure. The framework distinguishes between continuous structural propagation and discrete observational outcomes, aligning conceptually with quantum theory where the underlying state evolves continuously while measurement results appear discrete. This version clarifies the role of interaction and decoherence in the emergence of particle-like behavior.
