Bootstrap Predictions for Quantum Measurement: What Extended Electron Structure Implies for Interference, Entanglement, and the Born Rule

The Bootstrap Universe framework derives the electron's anomalous magnetic moment from icosahedral geometry, achieving 0.094σ agreement with experiment. The derivation reveals the electron as an extended structure with a physical field reach of 83,733 lattice units ≈ 4.4 pm. This paper identifies six testable predictions that follow from extended electron structure, without requiring any interpretation of quantum mechanics. (1) Electron diffraction visibility should show anomalous energy dependence in the 200–500 keV transition region, where the de Broglie wavelength crosses the Compton wavelength (212 keV) and kinetic energy approaches the rest mass (511 keV). (2) TEM diffraction through amorphous thin films should produce structured patterns beyond random scatter. (3) Double-slit interference should persist even when the barrier is thick enough to be classically opaque. (4) Bell inequality violation magnitude for electrons should show energy dependence absent from photon tests. (5) The lower bound on entanglement correlation speed should continue rising without limit. (6) The Born rule |ψ|² emerges from phase-averaged resonance geometry, predicting specific deviations for non-uniform phase distributions. All are falsifiable.
