Trying to picture this. If your bolt was fully up, the bolt was unlocked and out of battery, the case held by the extractor. I would think if it went off in that condition you'd have more than just a hole in the roof?? Not that I've ever had a rifle fire in that condition, but I would think the results would be more than just firing.
(To add, if the bolt is fully open, I'm pretty sure it is physically holding back the FP, that shouldn't be released until the bolt is closed, regardless of what the safety is doing. What you described seems pretty much physically impossible...(??) )
