Fully reproducible cosmology pipeline testing a Siamese Interference Dark Sector via three independent falsification probes (Hubble expansion, effective equation-of-state, interference entropy). Current model over-accelerates the Universe; future Study II will test inverted interference toward cosmic deceleration.

Code & data reproducing the Siamese Interference Cosmology analysis against Son & Lee (2025). We show that cosmic deceleration (q0​>0) emerges naturally from phase interference, predicting a falsifiable hemispheric anisotropy for Euclid/LSST.
