A framework combining derivatives of angular diameter distance with line-of-sight expansion rate enables model-independent tests of FLRW consistency and yields a nonparametric estimator for the cosmic density field independent of Friedmann equations.
Bootstrap-based symbolic regression on supernova and BAO data finds mild 2-4 sigma deviations from FLRW consistency relations, which if real would rule out most FLRW-based solutions to cosmological tensions.
