Team leaders of one B.LEAGUE game per statistic and period category (v1 feed only).
Endpoint: GET https://b-league.s3.amazonaws.com/web_json/v2_genius_contexts/{schedule_key}/{latest}.json
(the v1 feed, or the game page's embed, when v2 does not hold the game).
One row per (period category, category, team, player), ranked within the team (rank
1 = best; ties share a rank and tie_order orders them). category 1 points, 2
assists, 3 steals, 4 blocks, 5 rebounds, 8 shots blocked (other codes are unnamed).
Only the v1 feed (B3, B1/B2 2018-2020, the 2016-17 embed) publishes leaders: a v2
game gives a zero-row tibble.

A hoopR_data tibble with these columns:
| col_name | type | description |
| schedule_key | integer | B.LEAGUE ScheduleKey (key space: B.LEAGUE games, ONE global integer sequence across B1, B2, B3 and every season). The {schedule_key} every game wrapper takes and the schedule page's list-item id. |
| season | integer | Season END year (2026 = 2025-26), the feed's Year (the START year) plus one. |
| feed | character | Source feed of the row: v2 (v2_genius_contexts, B1/B2 from 2020-21) or v1 (v1_contexts: B3, B1/B2 2018-2020, and the 2016-17 / 2017-18 game-page embed). The feeds differ in id types, dates and some codes. |
| period_category | integer | Period category: 1-4 = quarters 1-4, 15 = first half, 16 = second half, 18 = whole game. Overtime codes are unverified. |
| category | integer | Leader category code, decoded by matching count to the box score: 1 points, 2 assists, 3 steals, 4 blocks, 5 rebounds, 8 shots blocked. |
| category_name | character | English name of category (points, assists, steals, blocks, rebounds, blocks_received); null for an unknown code. |
| rank | integer | Rank within the team for the category (1 = best; ties share a rank). |
| tie_order | integer | Order within a tied rank (1 = first listed). |

| player_name_j | character | Player name in Japanese (katakana for foreign players); null on team and game-level rows. |
| count | integer | The player's value in the category for the period category. |
