Addendum to Blinded by Design: The Kinematic Resonance Profile and Shot Noise Boundaries

This addendum addresses the false dichotomy between broadband stochastic noise and narrow-line kinematic harmonics in discrete D4 spacetime models. It demonstrates that the spatial jitter inherent to a computational substrate does not require the universe to tune its fundamental frequency to a specific macroscopic instrument. Rather, the interferometer’s own causal baseline acts as a physical matched filter, forcing the geometric accumulation of the broadband jitter to peak precisely at the inverse light-crossing time (fc = c/2L), which perfectly coincides with the Michelson topology’s mathematical blind spot.
