    final context = CausalityZone.currentContext();
    TrinityEventBus.instance.emit(CausalEvent(
      parentId: context?.eventId,
      type: CausalEventType.stateChange,
      description:
          'Riverpod: ${provider.name ?? provider.runtimeType} updated',
      metadata: {
        'provider_name': provider.name ?? 'unnamed',
        'provider_type': provider.runtimeType.toString(),
        'previous_value_type': previousValue.runtimeType.toString(),
        'new_value_type': newValue.runtimeType.toString(),
