Constraint-Preservation Anisotropy of the CMB Cold Spot in the Relativity of Matter: A Reproduced Signal, a Parameter-Free Structure, and a Source-Conditional Amplitude

What if the CMB Cold Spot is not an anomaly, but a signature? For more than two decades, the Cold Spot has remained one of the most persistent large-scale anomalies in the cosmic microwave background. It has survived the transition from WMAP to Planck, resisted simple foreground explanations, and has never received a universally accepted physical interpretation. This preprint asks a different question. Instead of treating the Cold Spot as an improbable fluctuation to be explained away, it asks whether its structure could be the observable imprint of a deeper gravitational constraint. Within the Relativity of Matter (RM), the characteristic Cold Spot signal is recovered on the Planck PR3 HFI maps, while the theoretical construction produces a remarkably rigid signature: a constraint-preservation trace amplification, a directional shear proportional to cos²(psi), and an active-source geometry scaling as M^(2/3). These features are not introduced to fit the observed Cold Spot. They emerge from the constraint structure of the theory. The amplitude is deliberately kept behind a firewall: it depends on an independently measurable population of active compact cores and is never calibrated from the observed CMB decrement. The result is therefore unusual in a field often dominated by parameter adjustment: the geometry predicts the structure first, and observation is left to decide whether nature actually uses it. The paper provides three direct routes to falsification: the angular shear signature, the M^(2/3) source scaling, and the requirement of a closed energy ledger without an ad hoc dissipative sink. The Cold Spot may still prove to be a statistical accident. But if its geometry carries the predicted signature, then one of the strangest features of the microwave sky may be pointing toward something considerably larger: a gravitational description in which matter, spatial curvature, compact objects and cosmic evolution belong to the same constitutive framework.
