Abstract Grand Unified Theories promised to complete the Standard Model. Unify the strong, weak, and electromagnetic forces into a single elegant structure, predict proton decay as the smoking gun, and solve the mystery of matter's dominance over antimatter in one move. The physics community built two generations of detectors to find that decaying proton. They are still looking. The GR-Razor does not wait indefinitely for a prediction to come true. The same instrument that dismantled ΛCDM, put Bostrom's simulation argument on trial, exposed the string landscape's thermodynamic detachment, and showed SUSY's hierarchy problem to be entropy bookkeeping that never closes is turned here on GUTs. Eight adversarial tests. No credit for a prediction that keeps retreating to higher energies every time a detector rules it out. The results follow the pattern. Five outright fails. One partial survival. One clean pass. The proton decay problem is shown here to be exactly what fifty years of null results suggest: a framework that identified the right destination and drew the wrong map to get there. Cosmological Pangaea does not need proton decay. It does not need a unification scale that no planned experiment can reach. It solves the matter-antimatter asymmetry problem geometrically (Pillar 16) without invoking baryon-number violation at inaccessible energies. It derives the three-generation structure of matter from first principles without a GUT gauge group. GUTs identified the right destination and drew the wrong map to get there. The map required a proton to decay. After fifty years and two generations of detectors, none has. The destination remains. The route is geometric. 1. 10.5281/zenodo.18736909 – Independent Cosmological Falsification Series. 2. 10.5281/zenodo.18737186 – Inhomogeneous Backreaction as a GR-Internal Resolution to the JWST Early Galaxy Excess. 3. 10.5281/zenodo.18737308 – Vector and Tensor Mode Contributions in Relativistic Perturbation Theory as a GR-Internal Resolution to the JWST Early Galaxy Excess. 4. 10.5281/zenodo.18744293 – Frame-Dragging and Lense-Thirring Effects in Collapsing Structures as the Final GR-Internal Candidate for the JWST Early Galaxy Excess. 5. 10.5281/zenodo.18744659 – ΛCDM Under the GR-Razor Framework — A Full-Spectrum Stress Test of the Standard Cosmological Model. 6. 10.5281/zenodo.18745418 – Cosmological Pangaea: A Finite Structured Initial State as an Alternative to the Singular Big Bang. 7. 10.5281/zenodo.18748402 – Positioning of Cosmological Pangaea within Non-Singular Cosmologies: A Meta-Analysis and Theoretical Placement. 8. 10.5281/zenodo.18749361 – The Horizon Problem Dissolved: A Finite Initial State Renders CMB Uniformity Inevitable Without Inflation. 9. 10.5281/zenodo.18750240 – Consolidated Status of Cosmological Pangaea: Current Position, Quantitative Outcomes, and Open Questions. 10. 10.5281/zenodo.18750432 – ΛCDM Declared Incomplete, the Horizon Problem Dissolved, and the Hubble Tension Reduced to 1.39σ by a First-Principles Quantum Bounce. 11. 10.5281/zenodo.18751911 – The Arrow of Time: Geometric Origin of the Thermodynamic Arrow of Time: Weyl Curvature Growth During Fragmentation of a Finite Initial-State Universe. 12. 10.5281/zenodo.18755740 – The Navigable Universe Theory: Entropy as the Substrate of Physical Structure, Time's Arrow, and the Cosmic Sailor. 13. 10.5281/zenodo.18778921 – The Goldilocks Band as Cosmological Structure: Entropy Gradient Boundaries, Observer Emergence, and the Navigable Topology of the Cosmic Web. 14. 10.5281/zenodo.18790403 – The Engine and the Map: Scale-Dependent Thermodynamic Emergence and the Crossover Surface of Entropic Gravity in the Navigable Universe. 15. 10.5281/zenodo.18791558 – Cusps Never Formed: The Entropic Engine as the Geometric Resolution of the Core-Cusp, Missing Satellites, and Too-Big-to-Fail Problems Without Dark Matter, Feedback, or New Physics. 16. 10.5281/zenodo.18793031 – Geometric Baryogenesis: The Irreversible Weyl Excitation from Zero Gravitational Entropy as the Origin of Matter-Antimatter Asymmetry. 17. 10.5281/zenodo.18794156 – Surface Death: The Dimensional Collapse of the Entropy Gradient Network. 18. 10.5281/zenodo.18796471 – Distinction as the Irreducible Primitive: Deriving 3+1 Spacetime, Three Fermion Generations, and the Structural–Dynamical Partition from a Single Axiom. 19. 10.5281/zenodo.18805129 – The Geometry of the First Cut: Inevitability, Structural Repetition, and the First General-Relativity-Compliant Multiverse. 20. https://zenodo.org/records/18827471 – The Story of How Cosmological Pangaea Unfolded. 21. https://zenodo.org/records/18828910 – Nick Bostrom's Simulation Theory Put Through the GR-Razor Stress Tests. 22. https://zenodo.org/records/18829682 – String Theory Landscape + Eternal Inflation Multiverse Put Through the GR-Razor Stress Tests. 23. https://zenodo.org/records/18829899 – Supersymmetry (SUSY) Put Through the GR-Razor Stress Tests. 24. https://zenodo.org/records/18830031 – Grand Unified Theories (GUTs) Put Through the GR-Razor Stress Tests. 25. https://zenodo.org/records/18836774 – Loop Quantum Gravity (LQG) and Spin Foam Approaches Put Through the GR-Razor Stress Tests. 26. https://zenodo.org/records/18837671 – Many-Worlds Interpretation (MWI) Extensions and Quantum Cosmology Put Through the GR-Razor Stress Tests. 27. https://zenodo.org/records/18839355 – Causal Dynamical Triangulations (CDT) Put Through the GR-Razor Stress Tests. 28. https://zenodo.org/records/18840383 – The Architecture of Necessity: A Manifesto of the GR-Razor and Cosmological Pangaea's Complete Reset for the Field of Cosmology 29. https://zenodo.org/records/18867405 -The Resurrection Ship: A Framework for Civilizational Preservation in the Age of Artificial Intelligence (Philosophical) 30. https://zenodo.org/records/18869920 -
