  assert(() {
    final parentId =
        response.requestOptions.extra['_trinity_event_id'] as String?;
    TrinityEventBus.instance.emit(CausalEvent(
      parentId: parentId,
      type: CausalEventType.networkEvent,
      description:
          'HTTP ${response.statusCode} ${response.requestOptions.method} '
          '${response.requestOptions.uri.path}',
      metadata: {
        'method': response.requestOptions.method,
        'url': response.requestOptions.uri.toString(),
        'path': response.requestOptions.uri.path,
        'phase': 'response',
        'status_code': response.statusCode ?? 0,
        'content_length':
            response.headers.value('content-length') ?? 'unknown',
      },
    ));
    return true;
