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.
