Query: On sign coherence of $c$-vectors   Given a finite dimensional algebra $A$ over an algebraically closed field, we
consider the $c$-vectors such as defined by Fu in \cite{Fu2017} and we give a
new proof of its sign-coherence. Moreover, we characterise the modules whose
dimension vectors are $c$-vectors as bricks respecting a functorially
finiteness condition.
