Whether purely-prime ideals must be purely-maximal

Must every purely-prime ideal of a commutative ring be purely-maximal? These are primality and maximality conditions taken within the lattice of pure ideals.

Why it matters and what counts as progress

Why it matters: The conjecture asks whether two notions coincide beyond the special ring classes where the implication is known.

What counts as progress: A general implication or a commutative ring with an explicitly classified pure-ideal lattice containing a purely-prime ideal that is not purely-maximal.
