Equisingularity conjecture for adapted HYM metrics

Let XX be a compact Kähler manifold and let lphalpha be a nef and big class on XX. Let T=θ+ddcφT=\theta+dd^c\boldsymbol{\varphi} be an adapted closed positive (1,1)(1,1)-current with minimal singularities in lphalpha, where θ\theta is a smooth representative in lphalpha. Let EE be a holomorphic vector bundle with a smooth Hermitian metric h0h_0. Assume that EE admits a TT-adapted HYM metric h=h0e2Sh=h_0e^{2S} with an h0h_0-Hermitian endomorphism SS. Equisingularity conjecture. The endomorphism SS is equisingular with φ\varphi, that is,

Sh0h0+φL(X).|S|_{h_0\otimes h_0^*}+\varphi\in L^{\infty}(X).

This conjecture concerns the precise asymptotic behaviour of adapted HYM metrics near the non-Kähler locus of a nef and big class. The preceding discussion explains that the available estimates do not currently ensure equisingularity, so the assertion remains open.
