Each problem carries a horizon badge indicating what would count as progress:

Sharp — A proof or single counterexample closes it.Incremental — Progress = a better bound or larger tractable class.Programme — A research field; not closable by one submission.Conceptual — No community-agreed success criterion (yet).
