Found by putting a real model at the end of the chain: a page of notes from a
theological book composed a prompt asking who wrote Matthew 4:17, and the
model rightly answered nothing for all twenty-three entries.
Those are scripture references, which is most of what the notes of such a book
are, and they are now not references at all — no record, and no question put
to anybody about them. A journal and its volume look similar on the page and
are still read as what they are.
Also: the stop that belonged to a marker no longer opens the entry after it.
