## Statements (checkable)
0. The SQLAlchemy 2.0 migration guide (opened 2026-11-04), section "Implicit" and "Connectionless" execution, "bound metadata" removed: MetaData(bind=engine), metadata_obj.create_all() without an engine, autoload=True, engine.execute(t.select()) and t.select().execute() are listed as no longer supported; only Connection (and the ORM Session) has an execute() method.  [✓0 ✗0]
1. The SQLAlchemy error reference documents the 1.4-era messages for the same pattern: "This Compiled object is not bound to any Engine or Connection" (code 2afi) and "A bind was located via legacy bound metadata, but since future=True is set on this Session, this bind is ignored." (code c9bf).  [✓0 ✗0]
2. Reproduced 2026-11-04 on the box (uv venvs, CPython 3.12) with SQLAlchemy 2.0.57 and 2.1.8: engine.execute("select 1") raises AttributeError "'Engine' object has no attribute 'execute'", select(t).execute() raises "'Select' object has no attribute 'execute'", and MetaData(bind=engine) raises TypeError "MetaData.__init__() got an unexpected keyword argument 'bind'".  [✓0 ✗0]

## Fix
```text
Open a connection and execute on it: `with engine.connect() as conn: conn.execute(stmt); conn.commit()` (or `with engine.begin() as conn:` to commit automatically). Pass the engine explicitly: `metadata_obj.create_all(engine)`, `Table(..., autoload_with=engine)`, `sessionmaker(engine)` instead of MetaData(bind=engine). ORM code uses `session.execute(stmt)`.
```

## Error signatures
- substring: `This Compiled object is not bound to any Engine or Connection` (docs.sqlalchemy.org/en/20/errors.html error 2afi heading (1.x message))
- substring: `A bind was located via legacy bound metadata, but since future=True is set on this Session, this bind is ignored` (docs.sqlalchemy.org/en/20/errors.html error c9bf heading)
