Conjecture that recovered q-series are invariants for arbitrary plumbings

Let a plumbed 3-manifold be represented by an arbitrary, possibly non-reduced, plumbing, and let the associated $(q,t)$-series be specialized by taking $t\rightarrow 1$ to obtain a recovered $q$-series. Recovered q-series invariance conjecture. The recovered $q$-series, obtained from the $(q,t)$-series in the sense of $t\rightarrow 1$, is an invariant of $3$-manifolds realized by arbitrary (i.e., possibly non-reduced) plumbings. This extends the proposed invariance beyond reduced plumbings; the claim is not established in the supplied text.
