Kaplansky-type zero-divisor conjecture for non-inert semi-latin quandles

Let k\mathbb{k} be an integral domain with unity and let XX be a semi-latin quandle, meaning a quandle whose left and right translations satisfy the relevant latin-type conditions, and assume that XX is non-inert. The quandle ring k[X]\mathbb{k}[X] is the k\mathbb{k}-algebra with basis XX and multiplication induced by the quandle operation. Kaplansky-type conjecture. The quandle ring k[X]\mathbb{k}[X] has no zero-divisors. This is proposed as a quandle analogue of Kaplansky's zero-divisor conjecture; the paper proves the claim for several orderable classes, but not in the stated generality.
