Geometric Entropy Asymmetry in Toroidal Cores

This preprint presents a minimal geometric mechanism by which local entropy asymmetry suppresses exact inversion of configuration-space paths. When applied to toroidal core geometries, the mechanism replaces divergent point singularities with finite recirculating structures and yields an effective logarithmic potential under coarse graining, corresponding to a $1/r$ force at large scales.The approach introduces no singular metrics, no preferred external frame, and does not require modification of gravitational field equations or additional matter components. The construction is intended as a preliminary technical note, prior to potential submission to arXiv (gr-qc), and provides a conservative, physically grounded framework for toroidal core regularisation.
