UHT–PTPC Methods and Data: Numerical Foundations of the Universal Heartbeat Theory

This technical companion paper documents the complete numerical methods and datasets used in all PTPC simulations, including the bounce integrator, entropy projection solver, and α-pipeline computation.All code is provided in Python and verified against analytic limits.The dataset confirms the reproducibility of the Universal Heartbeat Theory’s predictions for a(t), entropy evolution S(t), and α−1(me)=137.036\alpha^{-1}Figures and tables align with the main monograph “普世心跳理论与帕里张力相位塌缩:一个完整的宇宙学框架.”
