Variant used by the outcome route, e.g., choose a variant-specific success message.
This interaction identifier (FInteractionRuntimeVariantId) belongs to FInteractionRuntimeOutcomeEvent under InteractionRuntime.
Blueprint or editor workflows can write this value when constructing, overriding, or customizing the owning object.
Keep identifier values stable once content ships because saved state, prompt routing, and authored references may depend on them.
