Case contract

sits [student, period] with spd periods per day (day = p // spd). Report ["day", student, day] when a student has more than maxday distinct periods on a day, and ["eve_morn", student, day] when a student sits the last period of a day and the first period of the next day. Rows by student: day findings by day, then evening-morning findings.

Why this case matters

Daily exam limits and evening-then-morning sequences are common student-welfare rules.
