Case contract

Weekly fantasy scores are integer hundredths. Each head-to-head pair records a win/loss or a tie on equal scores (an odd team out has no head-to-head game). Every team also plays the league median: the middle score for an odd team count or the mean of the two middle scores for an even count; above the median is a win, below a loss, equal a tie. Return team -> [wins, losses, ties].

Why this case matters

Median-scoring leagues award a second result each week; the median definition and half-point comparisons decide playoff races.

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
regression: half-point median comparison	`{"T0": [1, 0, 1], "T1": [0, 2, 0], "T2": [2, 0, 0], "T3": [1, 1, 0], "T4": [2, 0, 0], "T5": [0, 2, 0]}`	`{"T0": [1, 1, 0], "T1": [0, 2, 0], "T2": [2, 0, 0], "T3": [1, 1, 0], "T4": [2, 0, 0], "T5": [0, 2, 0]}`	Failed
