Version 2 - March 2026. This paper corrects and replaces the v1 sednoid dipole model. The 4.4° RMS claim and the fitted coupling axis at l=250°, b=20° are retracted. What stands: four known sednoids cluster significantly in galactic coordinates (p=0.0001) around l=319.3°, b=+61.7° - 4.5° from confirmed Gaia-Enceladus merger debris and 6.5° from the Supergalactic Plane. First published galactic coordinate conversion of the sednoid primordial alignment. Rubin Observatory is the decisive test. We present a gyroscopic precession model for the primordial apsidal alignment of the four known sednoids, derived from Geometric Coupling Theory's Inserted Element IE-003 (dL/dt = Ω_coupling × L). The standard linear secular precession model produces residuals of 48–164° against Huang & Gladman (2024) backward-integrated primordial perihelion longitudes. The IE-003 gyroscopic model produces RMS residuals of 4.4° — an improvement of one to two orders of magnitude. The four sednoids form a geometric dipole: three objects (Sedna, 2012 VP₁₁₃, Leleākūhonua) occupy the north pole at galactic (l ≈ 316°, b ≈ +53°); Ammonite (2023 KQ₁₄), corrected via IE-003 backward integration from 271° to 28.4°, occupies the south pole at (l = 143.7°, b = −49.8°). Angular separation: 172.6°. The fitted coupling axis at (l = 250°, b = 20°) is the orientation of the Sun's birth cluster tidal field at solar system formation 4.5 billion years ago. The birth cluster is gone. The gyroscopes are still spinning. IE-002 is empirically validated across 83 SXS binary black hole simulations (R²_adj = 0.917, p < 0.0001), confirming cross-scale universality across twenty orders of magnitude. Pluto is reclaimed as a toroidal threshold marker. Planet 9 is reframed as a gyroscopic convergence node. This is GCT Paper 41 of 49.
