Thinking outside of the box at saving it. It's only a suggestion
Or have a machinist drill a hole at the crack end, shim the bottom of the headtube and wrap with a SS pipe clamp. (The shim shaped to make for a clean cylinder of the bottom of the DT weld and flair of the headtube above the headsetl.
That said, I had a fork fail a cm perhaps from that crack and paid for it with years of my life. We are talking the most critical area of the bike safety-wise by a lot.
Since this is a Lynskey, send them the photo and ask to have Lynskey himself look at it and comment. He's been around this stuff 30 years. If it a TiCycles and mine, I'd contact them. (Maybe 3 years fewer experience.)
