At first thought to be filling in the corridor from 7585, but quickly turned out to be a row of mudbricks that would run all the way along the plaster Locus:7584:051
This locus could be another supporting wall towards the conglomerate/mudbrick wall that runs in 7584. We probably have to open 7584 further to the S to see the full extend and function of this "unexpected" mudbrick wall/row
