SLE trace reversibility conjecture

Let $D$ be a simply connected domain, let $a,b\in\partial D$ be distinct boundary points, and consider the chordal $\textrm{SLE}_\kappa$ trace from $a$ to $b$, modulo reparameterization. SLE reversibility conjecture. For $\kappa\in[0,8]$, the chordal $\textrm{SLE}_\kappa$ trace is reversible: its law from $a$ to $b$ agrees with its law from $b$ to $a$, up to reparameterization. The source gives no resolution status.
