I once tore down a rebuilt gas engine that had 4 pistons with no rings, but the rebuilder put it together that way. I don't think there is any way for the rings to come off even when broken.

I've seen pieces eat their way out, but never an entire ring without severe damage

Even if broken into rather small pieces, both the piston and cylinder walls would be trashed before the rings could all work their way out completely.

This kinda makes me want to think maybe you possibly have a stuck, or sticking exhaust valve.
