Start by reproducing the INSERT OVERWRITE case with a partition value containing a trailing space in ClickHouse. Trace how the partition directory is generated and compare the paths shown in the report. Done means the data is written to one consistent partition directory and remains readable; no source files or tests are named in the issue.
