Here are an initial set of suggestions

[lewisjared]

Ahh I see that you ran ruff over the code which resolved a bunch of the formatting suggestions

[lewisjared]

@nocollier As mentioned on slack the CMEC output bundle has a log field which takes a log file

Nice stuff @minxu74. I think all that remains is adding a dependency on pydantic to the ref_core package.

uv add --package cmip_ref_core pydantic

Would you like to get this merged as is, and then do any follow up later. It is pretty self contained at the moment, but you would have to merge main back into this branch if you wanted to work on any other parts of the codebase as they have likely changed since you made this branch

@lewisjared I plan to submit another two commits tonight to address your suggestions and add more comments on the arguments of class methods. After that, if you and @acordonez agree, I can merge it to the main first as it does not interact with other ref components yet. We could create another PR to integrate the CMEC validators on other ref components. I wonder if it works?

I think that is a good idea. We are still actively building so I don't mind if this isn't 100% yet as it's more important to see how it works with the metrics providers
