The toroidal link conjecture for cyclic branched covers

Let LL be a prime toroidal link, and let cSigmaψ(L)cSigma_{\psi}(L) denote a cyclic branched cover of LL. Write NLSNLS for the property of not being an LL-space, LOLO for having left-orderable fundamental group, and CTFCTF for supporting a co-orientable taut foliation.

Toroidal link conjecture. All cyclic branched covers cSigmaψ(L)cSigma_{\psi}(L) of LL are NLSNLS, LOLO, and CTFCTF.

This is proposed as a broader toroidal case related to an earlier conjecture for prime satellite knots, where the conclusion was expected only for sufficiently large covering degree. Its resolution is not given in the source.
