Is there a reference for the fact that the functor of KahlerKähler differentials is a left Quillen functor on the category of $\textrm{CDGA}_k/B$$\mathrm{CDGA}_k/B$? Here $k$ is a field of characteristic $0$, and $B$ is some CDGA.
This seems easy to prove, but I would appreciate a reference in the existing literature.
This is a cross-post from MSE.
