Universal N-Fold Symmetry in SMBH Imaging: The Unified Theorem of Singular Manifolds and the n = 12 Anchor

While classical General Relativity treats the event horizon as an absolute causal boundary, the Darkon Big Boot Gauge Theory (BBGT) identifies it as a 2D + (Z) holographicinterface. This paper formalizes the Unified N-Fold Symmetry Theorem, categorizing supermassive black holes (SMBHs) by their discrete rotational operators. We demonstrate thatthe ”shadow” observed in interferometric data is a projection of high-order lattice locks,with the Great Attractor (GA) acting as the universal n = 12 (Poincar´e DodecahedralSpace (PDS)) anchor. We provide the coordinate mapping for the GA primary grid and theX/0 algebraic resolution for internal manifold reconstruction.
