The Azumaya-positive knot conjecture for L-space knots

Let KK be a fibered hyperbolic knot whose canonical component is Azumaya positive, meaning that the canonical component satisfies the paper's Azumaya-positivity condition. An LL-space knot is a knot in S3S^3 admitting a positive Dehn surgery yielding an LL-space, where an LL-space is a rational homology 33-sphere whose Heegaard--Floer homology has rank H1(M;Z)|H_1(M;\mathbb{Z})|.

Azumaya-positive knot conjecture. KK is not an LL-space knot.

The conjecture is motivated by examples of Azumaya-positive fibered hyperbolic knots whose Alexander polynomials have coefficients other than 00 and ±1\pm1, whereas LL-space knots have symmetrized Alexander polynomials with all nonzero coefficients equal to ±1\pm1. The claim remains open in the supplied source.
