Classification conjecture for maximum $(d,t)$-EKR sets in dual polar graphs

Let $Y$ be a maximum-size $(d,t)$-EKR set of generators in a polar space of rank $d$ and type parameter $e$, meaning that any two members of $Y$ meet in dimension at least $d-t$. A maximum $(d,t)$-EKR set classification conjecture. One of the following cases occurs:

1. $Y$ is the set of all generators on a fixed $(d-t)$-space.
2. $t$ is even, and $Y$ is the set of all generators meeting a fixed generator in dimension at least $d-\frac{t}{2}$.
3. $t$ is odd, and $Y$ is the set of all generators meeting a fixed $(d-1)$-dimensional space in dimension at least $d-\frac{t}{2}-\frac{1}{2}$.
4. $e=0$, $t=d-1$, $d$ is odd, and $Y$ is the largest example for $Q^+(2d-1,q)$ described by the cited reference.

This conjecture seeks a complete classification of maximum $(d,t)$-EKR sets, extending known classifications in special cases. The proposed families arise from the natural geometric configurations of generators; the general classification remains open in the source.
