@candleindark do you see how to bring this PR to the final version?

[candleindark]

Yes, I see how. I am currently working on improving the generation of https://github.com/candleindark/validation-diff-reports?tab=readme-ov-file so that it will actually have a meaningful summary (handling the "what are those 'null null null' and "$insert"" as well).

As far as the translation goes, we don't need to have Pydantic 2.10. It is just that Pydantic modifies its core schema with every one or two patch versions. But if you want to have this completed first, let me know and I will work on it first.

As far as the translation goes, we don't need to have Pydantic 2.10.

we don't until some of our down stream projects decides that 2.10 must be their minimally supported version for some reason (e.g. fixing some issue). That is why we should always strive to avoid such specification of demanding older version, and if introduced as a temporary workaround -- address it promptly.

re diff reports: Remember also that for validation the main goal is a result of figuring out if there is anything to do based on our dandisets, not really establishing overall framework which we might not use much again. So let's summarize what we learned on current state of those diffs and what to be done to dandi-schema or translation.
