Spent some time refactoring my Zola helper functions in Emacs Lisp. Went back and forth with ChatGPT and Gemini on performance vs robustness: path resolution, symlinks, binary I/O, guard semantics — the usual sharp edges.

Ended up with a version that’s not just “fast,” but actually hard to break in real-world usage.

For the record, Gemini(Pro) put up a good fight, but in the end it was a clear win for ChatGPT 5.2(Thinking).
