Breaking Changes

Code Generation Changes

• Self-referencing fields are now quoted with --disable-future-imports - When --disable-future-imports is set (no from __future__ import annotations and no native PEP 649 deferred evaluation on Python < 3.14), self-referencing and forward-referencing field annotations in regular BaseModel classes are now emitted as quoted forward references instead of bare names. Previously such annotations were left unquoted, producing invalid code that raised NameError (Ruff F821) at class-evaluation time. Output for the common case (with from __future__ import annotations or Python 3.14 native deferred annotations) is unchanged. Users who snapshot/golden-file generated output for the --disable-future-imports configuration with self-referencing models will see the annotation change from unquoted to quoted, e.g. children: Optional[List[Node]] → children: Optional[List["Node"]].
