The record states: Give an explicit \\(F\\in\\mathbb Q[X,Y]\\) and prove the equality \\(F(\\mathbb Z^2)=\\mathbb Z_{\\ge0}\\), including integrality and nonnegativity on every integer pair.",

Give an explicit \\(F\\in\\mathbb Q[X,Y]\\) and prove the equality \\(F(\\mathbb Z^2)=\\mathbb Z_{\\ge0}\\), including integrality and nonnegativity on every integer pair. Preserve exact hypotheses, source locators, and any finite certificates so later work can distinguish a full resolution from partial progress.",
