Weakly PIC2 conjecture for complete ancient Ricci flows

Let $(M^n,g(t))_{t \in (-\infty,0]}$ be a complete ancient solution to the Ricci flow with weakly PIC, meaning the stated curvature condition from the source. Weakly PIC2 conjecture. The solution has weakly PIC$_2$. This conjecture is stated as a generalization that directly implies the classification conjecture for Ricci shrinkers with weakly PIC. Its status remains open.
