Breuil--Mézard weight conjecture without a tameness hypothesis

Let r\overline r be as in the paper, and let Wgen(r)W_{\mathrm{gen}}(\overline r) be the subset of generic modular Serre weights. Let WgenBM(rp)W^{\mathrm{BM}}_{\mathrm{gen}}(\overline r_p) be the set of generic weights detected by the supports of the Breuil--Mézard cycles. Breuil--Mézard weight conjecture.

Wgen(r)=WgenBM(rp).W_{\mathrm{gen}}(\overline r)=W^{\mathrm{BM}}_{\mathrm{gen}}(\overline r_p).

This is presented as a generalization of the tame Gee--Herzig--Savitt weight conjecture to representations that are not necessarily tame at places above pp; the source does not state a resolution here.
