are created as follows in the database located at Defaults/ads_service/bundle_state under the table name ad_info_category contains:

sports
technology & sports
technology & sports-unix

Test Case:

• launch brave and enable rewards via brave://rewards
• visit https://www.popularmechanics.com/adventure/sports/a20066488/how-to-start-sailing/

Site visited https://www.popularmechanics.com/adventure/sports/a20066488/how-to-start-sailing/,
immediateWinner is sports-sailing and winnerOverTime is sports-sailing

• Once the website has been classified as sports-sailing, check Default/ads_service/catalog.json and you should see the following:

"segments": [
  {
    "code": "OfetQo4wKhT1",
    "name": "Sports-sailing",
    "parentCode": "b6O0KdkEyr"
  }
],

• open bundle_state and ensure that sports-sailing is appearing under both the category and ad_info_category tables, examples:

• ensure that you get the following ad while you're on https://www.popularmechanics.com/adventure/sports/a20066488/how-to-start-sailing/

[19679:775:0417/202911.463257:INFO:confirmations_impl.cc(853)]   type: dismiss

• ensure that the uuid of the ad that you received matches the sports-sailing ad_info_uuid that's under the ad_info_category table via bundle_state
• visit several boxing sports websites so you eventually get something similar to the following:

[19700:775:0417/205141.529707:INFO:ads_impl.cc(418)] Site visited https://www.boxingnews24.com/, immediateWinner is sports-boxing and winnerOverTime is sports-boxing

• trigger an ad and ensure that the ad uuid that you receive matches sports as we don't have any specific ads for sports-boxing
