So in this paper
arxiv.org/pdf/0801.2664.pdf a definition of "operadic module" is given. For the commutative operad, does this give bimodules or left modules? It seems like (3) of Definition 1.1, the "equivariance axiom," indicates that it gives left modules (or, rather, bimodules where the left and right action agree), but I'm not sure I'm understanding correctly. Is it clear to anyone else?
