Topological Causality Violation and the Butterfly Effect: An Algorithmic Resolution to the Time-Travel Paradox in QGEFT

The QGEFT spacetime has been shown to resolve causal paradoxes through the Butterfly Effect (Structural Divergence). Under the "Tri-State Causality Violation Protocol" on an $N=512$ vacuum graph, a forced time-traveler injection at Sweep 50 (the Past) does not tear the spacetime (Connected Components remains 1, rejecting Many-Worlds) and is not deleted by the vacuum (the traveler's edges survive at 100%, rejecting Novikov). Instead, the local energy cascade ($\Delta H = +0.08$) completely shifts the subsequent Metropolis trajectory, driving the spacetime to a different but self-consistent present with only 55.48% topological overlap to the original present.
