12-13 years ago, I ran the system that inlined Scholar and other results on the main search result pages. Anurag was still involved, but AFAIR Alex, the other author of the post who also had been there from the start, worked on most code changes. I would guess that things are more or less the same today. (Because it had such limited headcount, Scholar was known to lag behind other services when it came to code/infrastructure migrations.)
