Predicted iXAnation Comet Cluster (2026) and Echo (2027): Hyperbolic Interstellar Objects with OCS-Dominant Southward Leakage, Tests of the Trumpet Cosmology

The Trumpet Cosmology proposes a 4D horn-shaped continuum directed south (M-Axis), anchored at the Kaaba (M=0) and tilted ~30° south from the ti-plane defined by four ground points (Kaaba, Giza, Umayyad, Al-Aqsa). Following the dissipation of 3I/ATLAS (perihelion Oct 30, 2025), a 21× resonance predicts a cluster of at least three new hyperbolic objects — termed the iXAnation comets — leaking through the ti-wall in the southern sky. A second, distinct prediction follows from the same framework: the iXAnation Echo, a bright transient flare in the Orion Nebula expected in 2027.
