Just one small artifact that slipped into your PR. Also, don't forget to run make check-format & resolve any issues to make sure your code passes CI!

@Rishik00 Another contributor, @TensorCruncher, accurately pointed out that architectures like Olmo do not at present require a roundtrip test. I am going to close and merge the PR as is, thank you for your work on this.
