 * - current-revision trusted evidence still referenced by a requirement; and

 *
 * If the pinned set itself exceeds the target, retain every pin rather than
 * silently weakening completion auditing. In the common case, fill the
 * remaining slots with the newest unpinned records while preserving order.
