Positive grading is unnecessary for the bimodule 3-Calabi–Yau conclusion

Let $(Q,W)$ be a quiver with potential, and consider the conclusions of the bimodule $3$-Calabi–Yau result [?]. In particular, these include the corresponding conclusions for the quiver-with-potential interior construction and for the Frobenius cluster category construction. The no-positive-grading conjecture. The conclusion of the bimodule $3$-Calabi–Yau result, and hence those of the quiver-with-potential interior construction and the Frobenius cluster category construction, remains valid without the assumption that $(Q,W)$ admits a positive grading. The conjecture would remove the main technical hypothesis used to obtain these categorical constructions; the source gives no resolution.
