unless the archivist does not reduce the humidity today
unless the archivist will reduce the humidity today
unless the archivist would have reduced the humidity today

Unless is right because the risk continues if the archivist does not reduce the humidity. Adding does not after unless would reverse the intended condition because unless already contains the negative meaning.
