Formal Swiss Cheese conjecture for enriched 2-operads

Let VV be a symmetric monoidal category and let P\mathcal{P} be a VV-enriched 22-operad. Let P1\mathcal{P}_1 be the 11-operad obtained by restricting P\mathcal{P} to the 11-terminal 22-level trees, and let ActP(A)\mathrm{Act}^{\mathcal{P}}(A) denote the category of actions of P\mathcal{P} on a P1\mathcal{P}_1-algebra AA. Assume that the multitensor associated to P\mathcal{P} is closed from one side, with a right-adjoint internal Hom. Let Sym2(P)\mathrm{Sym}_2(\mathcal{P}) be the symmetrisation of P\mathcal{P}, and let Hoch\circle*1.5(A)=[A,A](id,id)\mathrm{Hoch}^{\:\raisebox{3pt}{\text{\circle*{1.5}}}}(A)=[A,A](\mathrm{id},\mathrm{id}). Formal Swiss Cheese conjecture. For a 11-terminal P1\mathcal{P}_1-algebra AA, the set-theoretical fiber ActP(A)\mathrm{Act}^{\mathcal{P}}(A) is equivalent to the comma category

Alg(Sym2(P))/Hoch\circle*1.5(A).\mathrm{Alg}(\mathrm{Sym}_2(\mathcal{P}))/\mathrm{Hoch}^{\:\raisebox{3pt}{\text{\circle*{1.5}}}}(A).

This gives a strong formal mechanism for describing Swiss Cheese actions through the internal Hochschild object; the supplied text presents it as a conceptual scheme under the stated closedness assumption, without specifying a resolution status.
