The Great Attractor: Genesis as a Parity-Preserving Gateway in Six-Throat Directed Geometry

Paper XI of the Six-Throat Directed Geometry program establishes Genesis as a finite parity-preserving material gateway on the extended E0 Zero-Region arena. The astronomical Great Attractor is identified with the M1 merger epicenter at the model-defined E0 topological symmetry center, F_M1 = Center(E0), while E0 remains the extended surrounding arena. A directed-sector polarization Q and coherence C convert branch identity into a dynamical observable. An exactly parity-invariant exponential matter coupling produces equal-and-opposite reverse-tension acceleration toward each packet's native sector. The resulting effective potential yields an exact same-sector return condition and a calculable coherence threshold. Coherence-deficient matter is handed to the inherited W1-W2-W3 tidal-processing hierarchy, while null radiation remains governed by the regular non-absorbing optical geometry. The accompanying reproducibility materials regenerate the three quantitative figures, audit the E0-to-W1 geometry and curvature, replay the frozen Cosmicflows-4 phase coefficients, and verify the gateway and filtration diagnostics.
