The Antimatter Wedge: Active Repulsion, Topological Chiseling, and the Algorithmic Origin of Cosmic Expansion in QGEFT

The injection of 15 unquenched antimatter defects (the Antimatter Wedge) directly between two bound mass nodes ($d=1$) induces an enormous localized stress ($\Delta H_{wedge} = -45.0$). This flips the thermodynamic balance of the system, dropping the total energy change of the edge-severing proposal to $\Delta H_{total} = -46.4517$. This forces the Metropolis-Hastings optimization engine to immediately sever the direct mass-connecting link (accepting the proposal with 100% probability), which drives the mass nodes to a distance of $d=2$ (active repulsion). Following the separation, the antimatter wedge is dynamically purified out of the active vacuum, leaving behind a stable, expanded spacetime metric.
