Case contract

Shifts [start, end] in minutes. For window W, evaluate windows [t, t + W) anchored at each shift start and sum the minutes of all shifts clipped to the window; report the maximum. Return [max in any 24h window, max in any 168h window, violations] where more than 960 minutes in 24h or more than 3600 minutes in 168h is a violation.

Why this case matters

Rolling-window fatigue limits catch hours concentrated across calendar-day boundaries.

One recorded failure
