Elements of the readme are a dead giveaway.

I can also tell you that this was written with Claude.

No issues with that in principle but I definitely would not trust Claude to get this stuff correct. Generally, it is quite bad at this kind of thing and usually in ways that are not obvious to people without experience.

No AI was used. I see no problems with using AI to write code whatsoever, but this isn't that. The formatting is my screw-up. I ran clang-format with a bad config, then tried to hand-fix the result and made it worse. The parenthesization is from defensive macro expansion that I inlined for the build and never cleaned up . The inline (smoke) test in the Makefile was a lazy hack from my local workflow that I forgot to replace before pushing and a proper test suite exists but the names/sections are in Telugu, my native language . I'll fix both and add.

You have to spend a ton of time on writing comprehensive test suite. It can do so many subtle bugs you would otherwise only find from vague customer report and reproducing by chance.
