RSIT Geometric Dark Energy: Joint Planck 2018 + DESI DR2 BAO + PantheonPlus (Locked geometric pair vs matched flat ΛCDM)
Year: 2026
Type: preprint
Abstract: Working verification note. Not a detection. Not a replacement of prior packages. Records the joint Planck 2018 + DESI DR2 BAO + PantheonPlus comparison of the locked RSIT geometric point (w₀ = −φ/2 ≈ −0.809, wₐ = −1/φ ≈ −0.618) against matched flat ΛCDM. Δχ² ≈ +1.5 (inside normal chain scatter). CMB and supernova contributions essentially identical. Zero extra free parameters. Lock unmoved. Raw chains remain local. Companion to earlier packages (including BAO + PantheonPlus note and locked claim collection).
