Is there a model of ZFC in which every Jonsson cardinal is also a Magidor cardinal, or can these two large cardinal properties be consistently separated at every relevant cardinal simultaneously?

Resolving this question would clarify the structural relationship between algebraic and combinatorial characterizations of large cardinals, giving set theorists a sharper map of the large cardinal hierarchy in the region around strongly compact and supercompact cardinals. It would also determine the extent to which forcing with small conditions can serve as a universal tool for separating or collapsing cardinal properties, with implications for the broader program of understanding which combinatorial principles are equivalent under forcing extensions versus outright independent.
