fastapi FTBFS and fails its autopkgtests with the current version of pydantic in unstable (2.12.0~a1-1 - I had no choice but to package an alpha release in this case because there was no other combination of pydantic/pydantic-core/etc. versions that was usable with the current rust-pyo3 transition).

Perhaps you could cherry-pick it into Debian? https://github.com/fastapi/fastapi/pull/14036 At build time there are four more failures in tests/test_forms_single_model.py; I'm not sure why they don't show up in autopkgtests. They all seem to be essentially this warning: pydantic.warnings.UnsupportedFieldAttributeWarning: The 'alias' attribute with value 'with' was provided to the `Field()` function, which has no effect in the context it was used. 'alias' is field-specific metadata, and can only be attached to a model field using `Annotated` metadata or by assignment. This may have happened because an `Annotated` type alias using the `type` statement was used, or if the `Field()` function was attached to a single member of a union type. This is due to https://github.com/pydantic/pydantic/pull/12028. I haven't had time to look into it properly yet, although I can if you need me to.
