That is enough wobbly in the narrative to split off the two versions that definitely lived in other time zones and were actually shown to die.

(As you'll recall, in most narratives, having clearly died in another story would be plenty of evidence that someone is meant to be considered a different person. Doctor Who should have to show us why before they get a pass. I mean - if they'd spread out Auton Rory for longer, or if they hadn't made clear Ganger Amy was actually Amy, we'd be arguing that still.)

So, combine the modern Claras as if they'd never been split, and leave the Oswalds from Asylum and Snowmen as their own pages unless different narrative evidence comes to light showing us how it isn't impossible that she's the same woman.

And The Doctor's statement that it's impossible is backed up by the fact that CO, COO, and Oswin tell him that they don't know him, that they don't recognize and have never met him before. To take The Doctor's theory/suspicion as fact is the wrong way to go. It's far too speculative to definitively call all three of them the same person with the information that we have right now.
