+Using the stamp sources from yesterday's image, I've been tracing the changes in source magnitude.  Something is clearly going wrong, as the sources magnitudes have unexplained offsets from the source mean values.  The mean values correspond well with the measured image flux, and the source magnitudes agree with the fake magnitudes, so this unknown offset is the cause of the poor difference images/stamp matching.
