Cosmological Update Dynamics: Progressive Concentration of Future Probability through Structural History

This paper extends the Selection-Driven Probability framework within Cosmological Update Dynamics (CUD) by introducing the structural-time evolution of future probability. Previous studies established structural distance, selection bias, and realization probability. The present work investigates how accumulated structural history progressively reshapes the future probability distribution through structural time. Rather than treating future probability as a static quantity, this paper formulates its continuous evolution as a consequence of accumulated structural history acting through the selection bias. This work forms part of the ongoing Cosmological Update Dynamics (CUD) series within the broader Onversology research program.
