Case contract

Division standings. teams rows are [name, wins, losses]. Win percentage is wins / games (0 for no games) shown with three decimals and the leading zero dropped (".500", but "1.000"). Sort by win percentage, then more wins, then name. The leader is the first sorted row; games behind = ((leader_wins - wins) + (losses - leader_losses)) / 2, shown as "-" when zero and otherwise with one decimal (negative values allowed). Return [name, pct, gb] rows.

Why this case matters

Standings pages and playoff-race widgets print win percentage and games behind.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
regression: equal percentage order	`[["Cats", "1.000", "-"], ["Suns", "1.000", "-7.0"], ["Jets", ".750", "-4.5"], ["Wolves", ".000", "0.5"]]`	`[["Suns", "1.000", "-"], ["Cats", "1.000", "7.0"], ["Jets", ".750", "2.5"], ["Wolves", ".000", "7.5"]]`	Failed
