## Which issue does this PR close? - Closes #24414. ## Rationale for this change Projection pushdown through `SortMergeJoinExec` could reuse stale join-filter indices and return incorrect results. ## What changes are included in this PR? - Rewrite the `JoinFilter` during projection pushdown. - Reject the swap when a filter column cannot be mapped. - Add an SQLLogicTest for the incorrect-result case. ## Are these changes tested? Yes. The SQLLogicTest verifies the physical plan and the expected `(1, 1)` result. The full Rust lint and extended workspace test suites also pass. ## Are there any user-facing changes? Affected queries now return correct results. There are no API changes. -- This is an automated message from the Apache Git Service.
