      abstract     = {Collective neutrino flavor conversions in core-collapse
                      supernovae begin with instabilities, initially triggered
                      when the dominant νe outflow concurs with a small
                      antineutrino flux of opposite lepton number, with ν¯e
                      dominating over ν¯μ. When these “flipped” neutrinos
                      emerge in the energy-integrated angular distribution
                      (angular crossing), they initiate a fast instability.
                      However, before such conditions arise, spectral crossings
                      typically appear within 20 ms of collapse, i.e., local
                      spectral excesses of ν¯e over ν¯μ along some direction.
                      Therefore, postprocessing supernova simulations cannot
                      consistently capture later fast instabilities because the
                      early slow ones have already altered the conditions.},
