Antimatter as a Topological Catalyst for Emergent Gravity: Phase Transitions and Scaffolding Dynamics in QGEFT

The QGEFT surrogate supports an optimal scaffolding regime ($T \approx 0.30 - 0.45$) where injected intermediate antimatter defects accelerate the rate of entropic gravitational contraction by more than a factor of two compared to a sterile vacuum control. At higher temperatures ($T \ge 0.60$), the scaffolding undergoes thermal melting (topological dissociation), and at low temperatures ($T \le 0.15$), the graph experiences glassy freezing. Following gravity-bridge stabilization, the antimatter is dynamically purified, leaving a stable gravitational remnant.
