Hm, "N" up there seems easily confused with "Normal".  Perhaps a less
mistake-prone coding would be
1    fires always0    fires neverN    fires in "Normal" modeR    fires in "Replica" modeother letters available for
otherfuture mode values?
 

If you consistently think of "origin" and "replica" modes then the
original proposal is better (using both 0 and O would be Real Bad),
but your use of "normal" and "replica" in the followup makes me wonder
which terminology is more common.
