6/// Which ceremony this one succeeds, as the successor's own opening
7/// records it.
8///
9/// The predecessor's head and version are part of the reference: a
10/// successor says which cut of the predecessor it was planned against,
11/// so "what had happened when this was decided" is answerable from the
12/// successor's first record instead of by guessing at timestamps. Both
13/// pins travel because the whole reason a successor exists is that the
14/// definition changed, and a handoff that did not record both sides of
15/// that change would lose the fact it was made for.
