"""Tests for the methods promoted onto SportsUpcoming / SportsRecent /
SportsLive from the nine plugin copies (phase B1 of the sports unification;
see docs/SPORTS_UNIFICATION.md).

Covered promotions:
- SportsRecent: `_get_zero_clock_duration` / `_clear_zero_clock_tracking`
  (+ the `_zero_clock_timestamps` initializer).
- SportsLive: `_is_game_really_over` / `_detect_stale_games`
  (+ `game_update_timestamps` / `stale_game_timeout`, and the
  `FINAL_PERIOD` / `CLOCK_COUNTS_DOWN` class attributes).
- SportsUpcoming: `_select_games_for_display`.
- SportsRecent: `_select_recent_games_for_display`.

The live pair is the risk centre: `_detect_stale_games` is the only caller
that *removes* games, so `_is_game_really_over` returning a false positive
silently drops a live game from the display. The canonical form deliberately
declines to treat a missing clock as 0:00 — the plugin variant that did so
dropped clockless sports (baseball) from the FINAL_PERIOD-th period onward.
That regression is pinned by
`test_missing_clock_at_late_period_is_not_over`.
