>>> No bulbs that I can see---yet.
I ask because you seem to be doing the opposite of what the seed requires. The normal practice is to keep seeds dry (at whatever temperature), then give them moist and warm(room temp) for germination and seed bulb production-3 months, then cold and moist(outside or in fridge)-3 months or more, then warm to get the first leaf to emerge.
It would be very unusual for a martagon seed to germinate in the fridge. They need warmth. Your seed in the cold may plump up, but they will just sit there and do nothing further. You are risking rot. Take them out and give them room temp and they will germinate. They can be in this first treatment for as long as 4 to 4.5 months, and the second possibly indefinitely.
