@jstvz

The current test failure is because CCI is on Pydantic 1 while Snowfakery is on Pydantic 2.

Do you want to:

a) upgrade CCI and Snowfakery to Pydantic 2 in a single coordinated release or

b) support Pydantic 1 and 2 simultaneously in Snowfakery so that they can upgrade in a staggered manner?

Obviously b) involves ugly cruft that will need to be removed eventually.

Option (a) is my preference.

@jstvz . Okay, ping me when the time comes if there are challenges on the Snowfakery side. It actually doesn’t thave a lot of Pydantic stuff in it and arguably what it does have should move to the CCI repo because it relates to CCI.
