## Jira Link [CALCITE-7453](https://issues.apache.org/jira/browse/CALCITE-7453) ## Changes Proposed - Preserve duplicate visible output names during SELECT * expansion instead of uniquifying them. - Carry exact source-field metadata for star-expanded duplicate columns so later validation and conversion do not rebind by name to the wrong field. - Use that exact metadata in qualification, type derivation, rolled-up column checks, ORDER BY resolution, and SqlToRel field access. - Report ambiguity when preserved duplicate output names make outer references genuinely ambiguous. - Update affected validator, converter, runtime, and baseline tests to reflect preserved duplicate names and corrected EXPR$N ordinals. -- This is an automated message from the Apache Git Service.
