We consider another two-stage quantum decoder that combines BP with a post-processing technique known as ordered statistics decoding (OSD). We expand on the results of Panteleev and Kalachev to provide further evidence that the BP+OSD decoder is a general decoder for all QLDPC codes that can be constructed from the hypergraph product. We define a spectrum of semi-topological codes and show the BP+OSD decoder applies generally across it, with a threshold in the region 9.9+/-0.2% on the Toric code, close to the value achieved by MWPM.
