However, in the face of late-time tensions, the nature of dark energy remains a central open problem. Modern precision cosmology offers a potential new window in the $w(a){\\rm CDM}$ framework, which provides a model-independent prescription for its unknown equation of state $w(a)$. A confrontation of $w(a){\\rm CDM}$ with data generally constitutes a nonlinear inference problem.
