 This registry can ground actor or caster names in the [spell](dnd-spell-artifacts.md)
 and [combat-turn](dnd-combat-turn-artifacts.md) artifacts. It is required to
 resolve the canonical `name` in an [NPC occurrence](dnd-npc-occurrence-artifacts.md).
-The [enemy-event artifact](dnd-enemy-event-artifacts.md) also uses it only for
-subject grounding and canonical display names.
+Occurrence consumers receive an ordered source-free `{id,name}` projection;
+spells, combat turns, and the [enemy-event artifact](dnd-enemy-event-artifacts.md)
+receive names-only grounding for actor or subject display. None of these
