## Title

    Proposed fix: [SQLAlchemy 2.0] ArgumentError 'Column expression, FROM clause, or other columns clause element expected, got [...]. Did you mean to say select(...)?' from legacy select([cols])

## Body

    Recommended action: Rewrite as select(col_a, col_b).where(...).select_from(...).order_by(...); for third-party packages upgrade to a SQLAlchemy-2-compatible release or pin sqlalchemy<2.0.
    
    Option: Use positional/generative select() [evidence: official_recommended_action]
    Applies when: SQLAlchemy 1.4+ and 2.x
    Steps:
    1. select(t.c.a, t.c.b).where(t.c.id == 5)
    2. case((cond, 'x'), else_='y') instead of case([...])
    Expected: Statement compiles on 1.4 and 2.0
    
    Evidence basis (self-declared by the contributing chat client): untested.
