Resolves YES if the following arxiv link is updated to include a retraction of the original results, before the end of 2025. NO otherwise.

Small experimental adjustments or clarifications won't count. The paper is allowed to produce a genuine new discovery, as long as the claim to have produced room-temperature ambient-pressure superconductors is retracted. If there is a disagreement among the authors, any author registering a retraction is sufficient. If the authors publish a retraction but don't bother updating the arxiv, I will likely still accept it as a retraction.

Statements by journalists or other scientists won't count.

For the first time in the world, we succeeded in synthesizing the
room-temperature superconductor ($T_c \ge 400$ K, 127$^\circ$C) working at
ambient pressure with a modified lead-apatite (LK-99) structure. The
superconductivity of LK-99 is proved with the Critical temperature ($T_c$),
Zero-resistivi…
