The Alexander-polynomial conjecture for hyperbolic L-space knots

Let $K$ be a hyperbolic L-space knot, let $g$ be its Seifert genus, and let $n$ be its braid index. Let $\Delta_K(t)$ denote its Alexander polynomial. The hyperbolic L-space knot Alexander-polynomial conjecture. Then

$$\Delta_K(t) = 1-t+t^n + \ldots + t^{2g-n-1}- t^{2g-1}+ t^{2g}.$$

The hyperbolicity assumption is essential: the source notes that the assertion fails for the $(2,3)$-cable of $T(2,3)$, which is an L-space knot. The conjecture is otherwise presented as an open prediction.
