Here are a series of false-color L257 Pancams of the current Oppy traverse stop. I'm still in the "arch the eyebrows and muttering 'fascinating' " mode so I don't have any words of wisdom right away. We can discuss over the next few day/sols before she moves on to the next miracle...

Back to the thin white line we've seen around the rim. Here's a crop of one of the northeast bays. It seems reasonable to infer this unit was level when deposited (if we are right that it is sedimentary). This image seems to show some uplift toward the centre of the crater. This would fit with a standard crater formation model I think. There are a few implications of this if it's right. The main one is that this bay would be beyond the original crater rim since the uplift occurs outside the rim during the formation event.
