/**
 * The state machine: what happens when a finding is seen again.
 *
 * Every rule here is about not losing an adjudication. A defect somebody ruled
 * by-design must not come back as new work the next time the judge files it; a
 * fixed finding that reappears must reopen rather than arrive as a second
 * issue; and a finding still open when it is seen again is refreshed, not
 * duplicated. Status transitions live here for the same reason: they are the
 * other half of the same machine.
