Reduced Gromov-Witten invariants without ghost bubble censorship

We give a definition of all-genus reduced Gromov-Witten invariants of symplectic manifolds by using effectively supported multivalued perturbations on derived orbifold/Kuranishi charts, which bypasses the hard analytical result of sharp compactification/ghost bubble censorship of Zinger, Doan-Walpuski, and Ekholm-Shende.
