This manuscript presents an empirical validation of the Triple Confined Origin Theory (TTO) and its foundation, the Unified Causal Principle (UCP), using exclusively pure observational data independent of the inferences from the ΛCDM model. We mathematically demonstrate, from first principles and the Critical Causal Constant (κCRIT ≈ 10−78), that the predicted value for the Hubble Constant (H0) from TTO is H0,TTO ≈ 73.30 km/s/Mpc [1], resolving the Hubble Tension out of physical necessity. Furthermore, the Intrinsic Anisotropy of the tripartite origin emerges as the geometric cause of the Cosmic Microwave Background (CMB) low-multipole anomalies (the "Axis of Evil"). Crucially, the TTO framework, incorporating Causal Dark Matter (MOC) as a geometric stress field, provides a statistically superior fit to the Baryon Acoustic Oscillation (BAO) data (χ2 TTO/MOC < χ2 ΛCDM) [2], establishing a unified, conceptually coherent, and empirically verifiable framework for fundamental cosmology
