Amdeberhan–Chen–Moll–Sagan valuation conjecture for generalized Fibonacci sequences

Let $f_n(s,t)$ denote the generalized Fibonacci sequence, and let $u_d$ be the $d$-adic valuation. For an integer $d'$, write $delta_{d'\mathbb{Z}}(n)=1$ if $d'$ divides $n$ and $0$ otherwise. Amdeberhan–Chen–Moll–Sagan conjecture. Suppose $s\ge 2$ is an integer and $d\ge 3$ is an odd integer. There exist integers $s'(s,d)$ and $d'(s,d)$ such that $d'\le d$ and

$$\nu_d(f_n(s,-1))=\delta_{d'\mathbb{Z}}(n)\nu_d\left(\frac{s'n}{d'}\right).$$

The paper states that the preceding valuation results prove this conjecture; the parser supplies no independent resolution evidence beyond that assertion.
