 DOCUMENTATION — every file must have a one-line module docstring. Classes get a one-line docstring. Keep it zensical: say what it IS, not what it does. No filler.
 
+NEVER USE DEPRECATED PATTERNS:
+- ✗ declarative_base() → ✓ class Base(DeclarativeBase): pass
+- ✗ Column(Type) → ✓ Mapped[type] = mapped_column(Type)
+- ✗ class Config: orm_mode = True → ✓ model_config = ConfigDict(from_attributes=True)
+- ✗ .dict() → ✓ .model_dump()
+- ✗ Optional[str] → ✓ str | None
+- ✗ session.query(Model).all() → ✓ session.execute(select(Model)).scalars().all()
+
 RULES:
 - Follow the REFERENCE IMPLEMENTATION patterns exactly
 - SQLAlchemy 2.0: DeclarativeBase + Mapped + mapped_column (not Column())

+FastAPI:

+  ✗ List[str] → ✓ list[str] (PEP 585, Python 3.9+)
+  ✗ Dict[str, int] → ✓ dict[str, int]
