contents We construct a model of ZFC with a singular cardinal $κ$ such that every subset of $κ$ in $L(V_{κ+1})$ has both the $κ$-Perfect Set Property and the $\mathcal{\vec{U}}$-Baire Property. This is a higher analogue of Solovay's result for $L(\mathbb{R})$. We obtain this configuration starting with large-cardinal assumptions in the realm of supercompactness, thus improving former theorems by Cramer, Shi and Woodin.
