QFM needs extending, and that will likely involve a significant refactor. The only way to test that it's still working robustly is to have a list of dataIds and human-confirmed results and run a cross check with the new code.
This ticket is to make a list of dataIds and the current results, and confirm that the table of results are correct by eye, and write a [notebook? script? something...] that can be run manually, with the data file produced, that reruns all the dataIds and checks that the results haven't changed.
