"""
Tests for scorebug bug fixes (#39 and #40).

#40: ScorecardTracker reads stale in-memory data — fix ensures get_scorecard()
     and get_all_scorecards() reload from disk before returning data.

#39: Win percentage stuck at 50% — fix makes parsing robust for decimal (0.75),
     percentage string ("75%"), plain number ("75"), empty, and None values.
     When parsing fails, win_percentage is None instead of a misleading 50.0.
