JCP-OBS-001: Observational Validation Protocol — Directional Coherence of Cosmological Anomalies Under the Glass Onion Theorem

Description: The Glass Onion Theorem (GOT) proposes that the observable universe is a metastable crystallized geometric projection of a pre-dimensional, non-metric substrate S₀, governed by a density cascade operator D̂₀→₁ and stabilized by substrate osmotic pressure Λₒsm. We present JCP-OBS-001, a preregistered multi-channel test of the GOT framework against eight independent cosmological anomalies including the CMB hemispherical power asymmetry, the Hubble tension directional bias, the >5σ quasar dipole mismatch, and the NANOGrav gravitational wave background anisotropy. The observed coherence Ξₒbs = 0. 6562 corresponds to Z = 3. 08σ (p = 0. 0010) against the ΛCDM isotropic null, validated by CLT derivation and N=100, 000 Monte Carlo realizations. Version 5. 5. 2 updates: DC Master Ledger expanded to DC-028 through DC-049 (22 entries). DC-048 adds the Bellazzini et al. proof that gravity emerges as a logical necessity from massive spin-3/2 particles, providing an independent formal bridge to the SU (2) substrate framework. DC-049 adds the Liu-Quintin-Afshordi Quadratic Quantum Gravity result replacing the Big Bang singularity with a high-energy phase transition, providing independent validation for the S₀→Σ crystallization model. DC-039 footnote extended to record the DESI five-year survey completion on April 15, 2026 (47 million galaxies, 38% overage), establishing the 2027 full-survey analysis as the definitive prospective test of the Λₒsm thawing dark energy prediction.
