Campana points and sums of four squareful numbers

I will present an asymptotic formula for the number of nonzero squareful integers z1, z2, z3, z4 which sum to zero, are coprime, and are bounded by B. Our result agrees in the power of B and log B with the Manin-type conjecture for Campana points recently formulated by Pieropan, Smeets, Tanimoto and Várilly-Alvarado. In this and some related examples, I will also discuss the compatibility of the leading constant with their conjecture.
