Case contract

Input {start, end (exclusive) day numbers, pauses: [[from, to)]}. Pause intervals are clipped to the period, empty ones dropped, then overlapping ones merged. The period end moves out by the number of distinct paused days. Return [new_end, paused_days].

Why this case matters

Pausing a subscription should extend paid service exactly by the paused time, no more and no less.
