 * The numeric `target_id` is rarely meaningful to a human reader of the

 * descriptive identifier for the entity at the moment the event was
 * recorded (reporter/consumer/policy name, category slug, IP/CIDR text,
 * job name, token prefix). Frozen at write time — renaming the entity
 * later does not rewrite history.
