Correct. No autograd: the expressions for the gradients are written out explicitly in C. There's a gradient check in tests/ that verifies them against centred finite differences on the published header, worst relative error 1.07e-08.

Specifically: I wrote it in Spanish first, which is my language, and then translated and condensed it into English with Claude. That's probably the blend you're picking up. The jokes, the structure and the decisions are mine; the English phrasing has fingerprints that aren't.
The code is more clear cut and it says so in the header: generated by AI under my direction. I wrote the architecture, the decisions and the validation, not most of the C.
I'd rather say that upfront than have someone find it later.
