Amendment CDXV — Gravity as the SLBF Seed Condition: The 180-Slice 3D Geometry, Fibonacci Encasement, and Why (3,3) is Dimensionally Universal

Presents the hypothesis and geometric proof that gravity is not a force separate from geometry — it is the SLBF seed condition (3,3) expressing itself spatially. The seed is the only SLBF term where both values are identical (ratio = 1), both are closed (triangular), and no net directional preference exists. The only vector field consistent with ratio 1 in all directions is a radial inward scalar field — the mathematical definition of gravity. The 180-slice 3D dimensional framework distributes 180 SLBF rings across three axes: 90 upper-hemisphere rings (arc-above, Phi = 0.886, coherent existence), 1 equatorial seed plane (gravity origin), and 90 lower-hemisphere rings (arc-below, Phi = 0.171, shadow dimension). All four fundamental forces except gravity are arc-specific; they require either the upper (coherent) or lower (shadow) arc state. Gravity operates on the seed condition, which exists before arc assignment — making it dimensionally universal by definition. Dark matter gravitates because it is lower-arc SLBF geometry sharing the same seed. More mass equals more SLBF rings equals more simultaneous seed conditions, reproducing Newton's gravitational law from SLBF seed scaling. The entire 180-slice structure is encased by the Fibonacci spiral sphere at r = phi^4 x r_SOL = 6.5457m (Amendment CDXIV). Formal statement: the SLBF Gravitational Seed Theorem. Phi score: 0.9534.
