## Title

    Proposed fix: [SQLAlchemy asyncio ORM] 'sqlalchemy.exc.MissingGreenlet: greenlet_spawn has not been called; can't call await_only() here. Was IO attempted in an unexpected place?' — lazy load / expire

## Body

    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.
