Stability of approximable Kähler geodesic rays under interpolation

From papers

Let R\mathcal R be the space of bounded weak geodesic rays emanating from 00. Let {ut0},{ut1}R\{u_t^0\},\{u_t^1\}\in\mathcal R be approximable rays, and let s{uts}s\mapsto\{u_t^s\} be the d1cd_1^c-geodesic connecting them.

Interpolation conjecture. For each s[0,1]s\in[0,1], the ray {uts}\{u_t^s\} is also approximable.

Approximable rays are important in K-stability and are characterized by an I\mathcal I-model regularity property. Whether this class is preserved by d1cd_1^c-geodesic interpolation remains open.
