Case contract

ledger: worker -> [overtime minutes charged, seniority rank (1 most senior), minutes already worked today]; offers: [minutes, workers who will refuse]. For each offer, candidates are ordered by charged overtime then seniority rank. Workers who would exceed 720 minutes today are skipped without charge; refusers are charged the offered minutes; the first remaining worker takes it and is charged and credited today. Return [taker per offer (or None), charged minutes by worker].

Why this case matters

Overtime equalization clauses require fair rotation of offers, including charging refusals.
