There are definetely things we haven't fully decoded yet. MB has hinted at it on several occasions. Whether that is the UA, or something else, I can't say. I think it's the UP we haven't really solved, given the vague answer for the last line in sound at planet orbit (ie. points to a locked system that we can't check), and the Spectrogram hasn't been satisfactorily solved with both the symbology and the left/right panes.
I'm afraid my mind isn't blown. Your overlay seems arbitrary at best. I can see Maia on top of a Beacon, another system lining up with a corner in the wall, in addition to a vague resemblance of some stars following the outer wall. Other than that, I really don't see how this fits with any of the other features of the ruins. If it was a star map, the beacons, item placements, or obelisk formations should line up with something as well.
So, either there's nothing there, or you're not doing a good job of explaining what you have found imho.
