Nekrasov's wheel-condition generation conjecture for tripled quivers

From papers

Let QQ be a quiver, let Q~\tilde{Q} be its triple quiver with canonical cubic potential W~\tilde{W}, and let TT be the torus of Example corresponding to the strong assumption, with coefficient ring RR and fraction field Frac(R)\operatorname{Frac}(R). Let S\mathcal{S} be the wheel-condition subalgebra of the shuffle algebra, let S˚\mathring{\mathcal{S}} be its spherical subalgebra, and write

Sloc=SRFrac(R),S˚loc=S˚RFrac(R).\mathcal{S}_{\mathrm{loc}}=\mathcal{S}\otimes_R\operatorname{Frac}(R),\qquad \mathring{\mathcal{S}}_{\mathrm{loc}}=\mathring{\mathcal{S}}\otimes_R\operatorname{Frac}(R).

Nekrasov's wheel-condition generation conjecture. The localized wheel-condition algebra equals the localized spherical subalgebra:

Sloc=S˚loc.\mathcal{S}_{\mathrm{loc}}=\mathring{\mathcal{S}}_{\mathrm{loc}}.

This is the cohomological analogue of the corresponding KK-theoretic wheel-condition generation statement. It is used to identify the localized CoHA with the full wheel-condition algebra, but the source does not provide a resolution.
