Contributor guide
Research direction
Start by reproducing the C++ API query from the issue against the two boolean rows, then trace how result columns are decoded when the first selected column is boolean. Compare the duplicated-column result with the expected true,true and false,false values; done means the first boolean column is no longer returned as null.
