Retrieved full publisher HTML of Yang et al., Exact counting of subtrees with
diameter no more than d in trees: A generating function approach, Information
and Computation307(2025)105353, doi10.1016/j.ic.2025.105353.

The publisher supplies an open-access CC-BY article, not a preview. Previous
audit's statement that this primary full text remained unavailable is superseded.

Inspected introduction, definitions, theorem/algorithm structure, concluding
remarks and target citation context; full-body searches for correlation,
conjecture, complete graph, Jensen and three-quarter variants.
Main subject is exact diameter-constrained subtree enumeration in a tree host.
Target Luo-Xu-Tian article appears in the general-background citation group
[23]-[29] and reference27, not as a finite adjacent-edge correlation theorem.
The only correlation occurrence concerns subtree counts versus Wiener index.
No matching finite3/4 inequality or theorem implying it was identified. This
closes one specific primary-source inspection gap; it does not prove priority.

Publisher's reference27 exposed an ordinary ViewPDF link for the target;
that link is being tested separately without assuming it grants full access.
