Abstract
We show by a uniform argument that every index one prime Fano threefold of genus can be reconstructed as a Brill-Noether locus inside a Bridgeland moduli space of stable objects in the Kuznetsov component . As an application, we verify Mukai's conjecture on the existence of dual embeddings of . Moreover, we establish a refined categorical Torelli theorem for and classify autoequivalences of . We also give an alternative disproof of Kuznetsov's Fano threefold conjecture.
