I’ve been advised by the breeder I know that dry storage is fine. Though like you said I initially used moist storage by default, like a pawpaw seed.
Stratification should speed the germination process.
I have had very fast (7 days) and high germination rates with the following:
Basic mechanical cleaning of the seeds - no soaks or bleaches etc.
Moist cool stratification in peat moss for 3 months or so
Sowing about 1/4 to 1/2 inch deep in seed starter mix and using a heat mat with humidity dome. Keeping the temp below 90. Do not let mix dry out.
