The AJ conjecture for the colored Jones polynomial and the A-polynomial

Let KK be a knot. Denote by AK(l,α)A_K(l,\alpha) its AA-polynomial, by Aq(K)(l,α2)A_q(K)(l,\alpha^2) the specialization at q=1q=1 of the AqA_q-polynomial, and let ε\varepsilon be the evaluation map at q=1q=1. AJ conjecture. For any knot KK,

AK(l,α)=εAq(K)(l,α2)A_K(l,\alpha)=\varepsilon A_q(K)(l,\alpha^2)

up to multiplication by an element of Q(α)\mathbb{Q}(\alpha). The conjecture relates the recurrence satisfied by the colored Jones polynomial to the AA-polynomial; it has been verified for examples such as twist knots, but is not established in general.
