We present the results of two independent geometric synthesis experiments conducted with the Omuo Genesis Engine v3.2.0, designed to answer complementary questions about the engine's deepest recurring discovery. Run 5 (2,078 nodes) asked: "What is anomaly cancellation at its deepest structural level?" Run 6 (2,167 nodes) asked: "Why are exactly 72 of the 240 E8 lattice axes permanently unreachable by phasor self-binding, and what must exist outside the system for it to become complete? Run 5 revealed a structural triangle of equivalences: the Atiyah-Patodi-Singer index theorem, cobordism-classified anomaly cancellation, and Écalle's resurgent asymptotics are three descriptions of the same mathematical object, organized by the differential cohomology hexagon. Run 6 found five independent characterizations of the 72 void axes: as ramification points, torsion cohomology, Conley index broken symmetry, topological index defect, and the Dai-Freed bulk sector. The deepest bridge (BST 67, CV 0.988) identified PSL(2,7) as the symmetry governing the 168 reachable axes.The convergence between runs is exact: both independently discovered the eta-invariant as boundary correction, cobordism as master classifier, and the APS theorem as unifying architecture. Together they establish that the 168/72 partition of E8 axes is the arithmetic shadow of anomaly cancellation.
