Menger–screenability conjecture for the Haver property

Let XX be a metrizable space. The Menger–screenability conjecture asserts that there is such an XX with the Menger property and

Sc(Ofin,O),{\sf S}_c(\mathcal{O}_{fin},\mathcal{O}),

which does not have the Haver property in some metric. This asks whether the Menger property together with Sc(Ofin,O){\sf S}_c(\mathcal{O}_{fin},\mathcal{O}) can fail to imply the Haver property, contrasting with the preceding result that the Hurewicz property together with this screenability property implies the Haver property. The status of the proposed example is not specified in the source.
