Modifications made in order for the code to run and give a reasonable answer.

The calculation of the partial derivatives in fisher_terms.py is different. I believe (?!) the new implementation is correct. The old implementation gave unreasonable results.

Implemented Om0-gamma model in rcrk24.

i do not understand the outer product you are performing now in the fisher part. since we are doing only vv, the outer product should be the same thing.

This is not very general but we can consider it to be true if we do not add the sigma_8 dependency.

Is this resolved, at least notionally? I spent the day looking for bugs and actually reimplementing to get the same answer.

I have now added a constant fs8 model.

I compared with carreres23 constant fs8 and got an answer that was close... The problem with a direct comparison is that the carreres23 implementation does not consider the redshift-dependent s8 that occurs when fs8 is constant.
