## Summary - In `DeleteOrphanFilesSparkAction.filteredCompareToFileList()`, when `compareToFileList` is used, files are filtered with `startsWith(location)`. If `location` doesn't end with `/`, this can also match sibling table paths (e.g. `/ns/my_table` matches `/ns/my_table_2`), incorrectly marking their files as orphans of the wrong table. - Normalize `location` to always end with `/` before filtering, mirroring the behavior of the default directory-listing path. - Scoped to Spark 4.1 (latest supported version per repo policy); older Spark versions can be addressed in a follow-up if this is approved. ## Motivation Prevents `deleteOrphanFiles` with a custom `compareToFileList` from deleting files belonging to a different table that merely shares a path prefix with the target table's location. -- This is an automated message from the Apache Git Service.
