Author of Diamond types (and the data sets you’re using) here! Congratulations on getting this insane performance. I’d love to know how you’re doing it - that’s truly excellent work. I didn’t know it was even possible to get javascript to go that fast on this problem. And I say that as someone who has thought about crdt / text performance way more than is reasonable.

RIP my morning. I’m going to have to pour through your code to see how you’ve pulled this off. Do you have anything you recommend I read to understand how your algorithm works?
