What it changes
Problem #516 belongs to analysis. The wiki sees a literature search here: if the solution held, it would apply to the actual problem and not to the statement as it was posed.
What remains unclear
The sources read do not say how the statement was misstated or where the solution was found, and mention no examination by third parties. They also do not separate what is due to each of the tools named.
