Reconciliation Frames and Duration Conservation in Dual-Asymptotic Proper-Time Geometry

Recent analysis of relativistic asymptotic structure suggests that proper-time geometry possesses dual asymptotic behavior: compression near lightlike motion andrelational expansion away from it. While special relativity remains locally consistentunder this interpretation, large divergences in accumulated proper time introduce aglobal comparison problem between observers. This paper demonstrates that a reconciliation structure naturally emerges as a bookkeeping requirement for comparingworldlines across dual asymptotic regimes. The resulting framework introduces a normalization reference, termed a reconciliation frame, which preserves relational consistency without modifying the underlying equations of relativity.
