Topological Osmosis and Indirect Spacetime Curvature in QGEFT: The Bulk as an Antimatter-Purification Channel and Geometric Origin of Galaxy Rotation Support

Key Points

The aim is to explore the roles of bulk structures in topological osmosis and dark matter dynamics.
Utilized QGEFT multi-graph surrogate model for analysis.
Examined purification dynamics of antimatter-like defects across static and adaptive branches.
Analyzed gravitational response through chi-squared metrics comparing different models.
The adaptive bulk reduces purification time for antimatter-like defects from 50 sweeps to 1 sweep.
The bulk is favoured as an indirect gravitational-response modifier with a reduced chi-squared of approximately 0.994.
Performance metrics indicate a significant improvement over QGEFT-core and NFW models in gravitational responses.

Abstract

The current Paper 63 benchmark does not claim that the observed cosmic baryon asymmetry or the full dark-matter program has already been derived from first principles. It does show that, in the verified QGEFT multi-graph surrogate, the bulk plays two distinct but compatible roles. First, adaptive bulk bridges act as a true topological-osmosis channel, reducing the purification time for `16` injected antimatter-like defects from `50` sweeps in the static branch to `1` sweep in the `adaptive-dual` branch. Second, the same bulk structure is strongly disfavored as a standalone shadow halo on DDO154 (`reduced chi2 ≈ 75.826`) but favored as an indirect gravitational-response modifier (`reduced chi2 ≈ 0.994`), outperforming both `QGEFT-core` (`≈ 1.183`) and `NFW` (`≈ 10.435`). The defensible conclusion is therefore that the bulk behaves here as a thermodynamic purification valve plus a large-scale geometric stress-relief channel, not as a particulate dark sector.
