Entry surface represented by this state.
This interaction identifier (FInteractionRuntimePointId) belongs to FInteractionRuntimeMultiParticipantEntrySurfaceState under InteractionRuntime|MultiParticipant.
Designers configure this value in the owning asset or object details panel, while Blueprint logic can read the resolved value at runtime.
Keep identifier values stable once content ships because saved state, prompt routing, and authored references may depend on them.
