Summary: Using DESI DR2 hints of evolving dark energy, the work shows alignment with the Swampland Transplanckian Censorship Conjecture and uses swampland TCC criteria to constrain EoS parameterizations (CPL/BA/JBP/EXP/LOG) and test modified gravity, implying viable scenarios must asymptotically transition to deceleration.
