model_validate() returns None instead of model instance

[simontaurus]

Problem

LinkedBaseModel.model_validate(data) returns None instead of the validated model instance. The override calls super().model_validate() but doesn't return its result.

Workaround

# Instead of:
instance = MyModel.model_validate(data)  # returns None

# Use:
instance = MyModel(**data)  # works

Expected behavior

model_validate should return the constructed instance, matching pydantic v2's standard behavior.

Location

oold/model/__init__.py, line ~430 — the model_validate classmethod needs return super().model_validate(...).
