Coherence conjecture for multiplier ideal sheaves of Griffiths semi-positive metrics

Let (E,h)(E,h) be a holomorphic vector bundle over an nn-dimensional complex manifold XX with a singular Hermitian metric hh. Let Griffiths**\operatorname{Griffiths}-semi-positive** mean that hh has Griffiths semi-positive curvature. The higher rank analogue of the multiplier ideal sheaf, denoted by E(h)\mathcal{E}(h), is coherent.

Coherence conjecture. If hh is Griffiths semi-positive, then E(h)\mathcal{E}(h) is coherent.

Coherence is known in several cases, including metrics with stronger positivity such as Nakano positivity, but the Griffiths semi-positive case is posed as the natural question because Griffiths positivity is strictly weaker than Nakano positivity.
