This preprint proposes a minimal gravitational-wave calibration test of whether gravitational-wave luminosity distances and electromagnetic luminosity distances remain consistently synchronized over cosmic time. Within an effective-field-theory description of dark energy, the paper isolates a single Planck-mass run-rate parameter, αM0, while fixing the background expansion to ΛCDM. The resulting framework links gravitational-wave distance propagation, growth/lensing consistency, and late-time onset into a falsifiable phenomenological test. Forecasts using simulated standard-siren catalogs indicate that next-generation gravitational-wave observatories could probe percent-level calibration drift.
