>
> Adaptive execution can continue planning work after a materialized query
> stage proves that a branch is empty, including plans wrapped by
> sort/project/columnar conversion operators. This can leave obsolete exchange
> stages running and may surface cancellation failures from stages that are no
> longer relevant to the final plan.
> This issue tracks preserving emptiness propagation through those wrappers,
> handling aggregate row-count semantics correctly, and ignoring cancellation
> failures from obsolete stages that AQE intentionally replaces.
