The site labels the problem SOLVED on its problem page as accessed 2026-09-09, the page last edited 5 September 2026 (OPEN in the site's export of 2026-09-04). Its commentary credits GPT, prompted independently by Price and by pipeline-math, with proving that such an $A$ exists for $f(n)=n^d$ and every even $d\ge6$; that is the range in which Price's construction tiles the full image, while the pipeline-math manuscript treats $f(X)=X^{13}$ only. The claim pages pipeline-math and Price record the results and their acceptance; Sekanina's records the refereed negative answer for $f(X)=X^2$, and a fourth claim is pending. The derived claim value is proved where the site's SOLVED reads as answered, because the question asks whether such an $f$ and $A$ exist and the accepted claims prove that they do.
