    There used to be a warning at infinity-Lie algebra cohomology about whether or not a certain functor needs to be regarded as a derived functor in order to get the correct homotopy-theoretic interpretation of oo-Lie algebroid extensions. I think I have now spelled out at synthetic differential infinity-groupoid the required details and so I replaced that warning with a pointer to a section in that latter entry.

    All this can do with a good bit more polishing. I’ll see what I can do eventually.

    Have added pointers to the recognition theorem for homotopy fibers of L L_\infty-homomorphisms – hence for L L_\infty-algebra extensions classified by L L_\infty-cocycles – which is theorem 3.1.13 in Fiorenza-Rogers-Schreiber 13 to
