Case contract

A student's exams [id, start, duration] and an extra-time percentage. Extended duration = ceil(duration * (100 + pct) / 100), then rounded up to a multiple of 5 minutes. In start order (ties by id) a pair conflicts if the next start is earlier than the previous extended end plus the rest minutes. Return [[id, extended end] in order, conflicting pairs].

Why this case matters

Access arrangements extend sittings; the timetable must still leave rest between a student's exams.
