Testable Predictions (Companion Paper V2.1): Crucially, this framework translates its conceptual architecture into actionable, testable physics. Mapped into the Standard-Model Extension (SME), the theory predicts specific signatures of Lorentz Invariance Violation (LIV) that can be found in existing data: A 23h 56m Sidereal Variation and spontaneous vacuum torque in precision Casimir Effect measurements. Isotropic photon bursts and local CP-Violation during anomalous Light-by-Light Scattering in ultra-relativistic Lead-Lead (Pb-Pb) Collisions (Fold-Ruptures). Chiral asymmetries in Gravitational Lensing data caused by vacuum torsion. All predictions follow from the Pi-metric microstructure of the Boundary as described in the companion framework paper: Actualisation Theory V5, DOI: https://doi.org/10.5281/zenodo.19885921
