Visualizing the Kerr-Sedenion Phase Transition: Computational Verification of the Stiffness Collapse Horizon

A computational study of the Kerr Black Hole metric within the framework of Axiomatic PhysicalHomeostasis (APH) is presented. Utilizing a custom Wave-Particle Transport (WTS) raymarchingengine, we visualize the Event Horizon not as a coordinate singularity, but as a Stiffness CollapseHorizon where the geometric stiffness of the vacuum (β) approaches zero. By simulating the relativisticgeodesics of a Shakura-Sunyaev accretion disk, we recover key observational signatures: the EinsteinRing, relativistic Doppler beaming, and the frame-dragging asymmetry. Crucially, our simulationconfirms the APH prediction that the horizon functions as a domain wall between the associativeOctonionic vacuum and the non-associative Sedenion bulk. This work provides a visual laboratory fortesting the thermodynamic continuity between the Neutron Star crust and the Sedenion Core.
