OptionalactorUUID of that token's actor, when it has one (for predicate scoping).
The region's id (for predicate scoping to one region).
The region's display name.
UUID of the region the event fired on.
UUID of the scene the region belongs to.
UUID of the token that entered/exited/acted.
The context payload common to every scene-region trigger (issue #593). The bridge (a SoHL
RegionBehaviorType) resolves the entering token to its actor at the Foundry boundary, so the logic layer sees only UUIDs and names — a predicate can scope a subscription to a specific region (regionId) or a specific character (actorUuid).
