Yeah, she dead bud. Sorry. Anything is repairable for a price, but you probably don’t want to spend that on this

Exceptionally.

Your seat post clamp is going to break off. Result will be that your seat will spin. Its still going to be clamped, so it wont drop.
Id consider that a non-critical failure and would ride it tile it breaks.
Since that is not really structural, you could totally weld that back on and salvage the frame. If you have a buddy with a tig welder, it would take them 15 minutes. 10 minutes if you have him do it before it fully breaks off.
Id also consider drilling a small hole at each end of the crack as a stop-gap. That will stop the crack from spreading more. If you did this when the crack was a lot smaller, you wouldnt even have to repair it.

People here seem to be forgetting that aluminum frames are heat treated after welding. You don’t have access to that kind of facility unless you’re a manufacturer.
That said, it looks like the crack is outside the main triangle (or quadrilateral in GT-speak). Either it cracked from seatpost flex or the post was run too shallow in the seattube. I wouldn’t trust the clamp anymore. But I would consider grinding the top down flat to the height of the top tube or so, and gluing in a nice long seatpost at the perfect height.

Looks like she got upgraded to a display piece.
