DESCRIPTION:The DUNE far detector offers a unique\, flavor- and helicity-t
 agged view of neutrinos from a Galactic core-collapse supernova\, with par
 ticular sensitivity to the supernova $\\nu_e$ spectrum. In this talk\, I w
 ill first discuss how to obtain precision measurements of this spectrum us
 ing a data-driven strategy that calibrates the uncertain $\\nu_e$-argon cr
 oss section with solar and muon-decay-at-rest neutrinos as standard candle
 s. With this helicity tagging\, complementary to the antineutrino sensitiv
 ity of other supernova detectors through inverse beta decay\, we can measu
 re neutrino-antineutrino asymmetries as a probe of ultralight vector dark 
 matter coupled to lepton number\, such as $U(1){B-L}$ or $U(1){L_i-L_j}$.\
