/**
 * A suppression that names no known check must be reported, not silently
 * ignored (M-BUG-28, prediction 8).
 *
 * This is what makes the ID-semantics change safe to ship: pins written against
 * the old positional numbering either still name a real check, or they now name
 * nothing — and "nothing" has to be visible. A silently-dead suppression is the
 * same failure the old scheme had, just in the other direction.
