Case contract

Seven daily worked minutes (Mon..Sun) and an hourly rate in cents. Daily: first 480 minutes regular, next 240 at 1.5x, beyond 720 at 2x. If all seven days are worked, day 7 pays its first 480 minutes at 1.5x and the rest at 2x. Regular minutes above 2400 in the week move to 1.5x (daily overtime minutes never count toward the weekly threshold). Pay is computed exactly and rounded half up to a cent once. Return [regular, ot15, ot2, pay_cents].

Why this case matters

Overtime classification mistakes are a classic payroll-roster defect: pyramiding, seventh-day rules and rounding stage all change what workers are paid.
