Recommended action: Eager-load needed relationships (selectinload/joinedload) in the query, use async_sessionmaker(expire_on_commit=False), use AsyncAttrs + await obj.awaitable_attrs.rel for explicit loads, or set lazy='raise' to surface the problem early.
Option: Load eagerly / avoid expiry [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. select(A).options(selectinload(A.bs))
2. async_sessionmaker(engine, expire_on_commit=False)
3. class Base(AsyncAttrs, DeclarativeBase): ... then await a.awaitable_attrs.bs
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
