Tangent–cotangent equivalence conjecture for derived Γ\Gamma-schemes

Let XX be a Γ\Gamma-scheme, let TXΓ\mathbb T_X^\Gamma denote its Γ\Gamma-tangent \infty-category, and let LXΓ\mathbb L_X^\Gamma denote its cotangent complex. Tangent–cotangent equivalence conjecture. There exists a natural equivalence

TXΓR ⁣HomΓ(LXΓ,OX).\mathbb T_X^\Gamma\simeq\mathbf{R}\!\operatorname{Hom}_\Gamma(\mathbb L_X^\Gamma,\mathcal O_X).

This would identify the Γ\Gamma-tangent object with the derived Hom from the cotangent complex, but the source gives no evidence of resolution.
