Introduces reionization relics as a large-scale cosmological probe for warm dark matter, forecasting m_WDM constraints of >5.0 keV (Lyα alone) and >7.1 keV (combined with 21 cm) at 95% CL.

No CMB-consistent CPL dark energy model can simultaneously fit both the BAOtr and DESI datasets; the 3.7-sigma disagreement at z=0.51 sets an irreducible floor.
Non-conserved biased tracers debias more rapidly than conserved tracers, leading to time-dependent suppression of large-scale power.
