Summary

Ty flags missing required fields for pydantic.BaseModel but not for sqlmodel.SQLModel subclasses, both using Pydantic v2.

Minimal repro

from __future__ import annotations

from pydantic import BaseModel
from sqlmodel import SQLModel


class ExamplePydantic(BaseModel):
    number: float


class ExampleSQLModel(SQLModel):
    number: float


ExampleSQLModel()  # ty: no error (bug)
ExamplePydantic()  # ty: error (good)

Expected

Expected: Both ExampleSQLModel() and ExamplePydantic() are flagged as missing required field number.
Actual: Only ExamplePydantic() is flagged, ExampleSQLModel() passes.
