The $(d-2)$-leaky forcing number conjecture for hypercubes

Let $Q_d$ be the $d$-dimensional hypercube, and let $Z_{(d-2)}(Q_d)$ denote its $(d-2)$-leaky forcing number.

Hypercube leaky forcing conjecture.

$$Z_{(d-2)}(Q_d)=2^{d-1}.$$

The paper establishes an upper bound for this quantity, but the matching lower bound is not known; partial results for hypercubes motivate the conjectured equality.
