Coordinate independence of the q-de Rham complex

From papers

Let RR be a smooth Z\mathbb Z-algebra, and let :Z[T1,,Td]R\square:\mathbb Z[T_1,\ldots,T_d]\to R be an étale framing. The framed complex q ⁣- ⁣ΩR[[q1]]/Z[[q1]],q\!\operatorname-\!\Omega^\bullet_{R[[q-1]]/\mathbb Z[[q-1]],\square} is a complex of Z[[q1]]\mathbb Z[[q-1]]-modules. The coordinate-independence conjecture. The framed complex is independent of the choice of coordinates up to canonical quasi-isomorphism; more precisely, there is a functor Rq ⁣- ⁣ΩRR\mapsto q\!\operatorname-\!\Omega_R to the \infty-category of EE_\infty-Z[[q1]]\mathbb Z[[q-1]]-algebras, computed by the framed complex for every framing. This would make the construction intrinsic and allow it to glue over smooth schemes.
