Paper 4 in the Kottayil Triad series. Builds on 20 quantum hardware experiments in DOI 10.5281/zenodo.19151110. Proposes SU(3)xSU(2)xU(1) Standard Model gauge group from four observer angles of one rotating Kottayil Tetrahedron. Face 1 = SU(3) confirmed experimentally. Face 2 = SU(2) doublet. Face 3 = U(1) phase. Face 4 = gravity candidate supported by JT gravity thermal confirmation. Includes IDRIS Avida four-face digital organism evolution platform as computational validation. Chain confirmed: Kottayil Triad -> K3 -> SYK -> JT Gravity.
