A professional lab with PhDs and real scientists working at it will report they received a package containing alleged superconducting material from any of the LK-99 researchers or Quantum Energy Research Center.

The report can be a press release, twitter post, blog post, etc. but should be verifiable as being from a real lab.

Edit: there is a shorter term version which is currently waiting for data since there are some Korean language claims of this with very weak validation. This market will likely also be hard to resolve.
