Assess genuineness and significance of the p=3 d-type instanton instability
Ascertain, for the p = 3 truncated single-cut saddle that remains the only self-consistent single-cut solution where the dominant saddle ceases to exist, whether the observed d-type instanton condensation constitutes a genuine instability contributing to the original path-integral contour, and, if so, characterize the physical significance of this instability in the dual gravitational description.

Whether it indicates a genuine instability along the saddle, i.e. whether it contributes to the original contour of integration in a way that would be revealed by a full Lefschetz thimble analysis, is left unresolved in this work, as is the question of any physical significance such an instability might carry.
