# The tail of the pair below comes to a formation that is no copy of an object
# of the world and whose φ chain ends in nothing, so a 'remint' step has no
# symbol to answer for it. It writes an 'unreminted' line naming the term
# instead of minting a symbol nobody can build, and the firing gets stuck the
# way one whose 'join' line could not pair its branches does (#1923).
