Abstract
This work introduces a novel model of quantum entities as unified, physically extended wavefields, forming the basis for a testable realist, holist framework for quantum measurement and collapse. Unlike interpretations that postulate hidden variables, observer-induced effects, spontaneous stochastic collapse, or multiverse branching, this model derives the Born rule from the squared-amplitude structure of an extended wavefield undergoing localized, interaction-induced collapse. Central to the model is a reinterpretation of the Heisenberg uncertainty principle - not merely as a statistical or epistemic limitation, but as a dynamical relation between localized energetic interaction and wavefield localization. This framework yields testable predictions about how weak, intermediate, and strong quantum interactions modulate spatial localization - predictions consistent with existing experimental findings. The upshot is a unified, falsifiable alternative to standard interpretations, and a foundation for a broader research program in wavefield interaction mechanics.
