You're right, Han didn't define DeepResearch as "a cosmetic enhancement". I quoted his sentence long definition:

> DeepResearch builds upon DeepSearch by adding a structured framework for generating long research reports.

But then called it "a cosmetic enhancement" really to be slightly dismissive of it - I'm a skeptic of the report format because I think the way it's presented makes the information look more solid than it actually is. My complaint is at the aesthetic level, not relating to the (impressive) way the report synthesis is engineered.

So yeah, I'm being inaccurate and a bit catty about it.

Your explanation is much closer to what Han described, and much more useful than mine.
