Late arrivals belong on the tape.

We used to drop usage that showed up after close into a “adjustments” bucket nobody could audit. Finance asked for a dump. Engineering sent a CSV. The invoice still lied.

14.2 prints the late-arrival window on the event tape. The line is held, not repaired. If you open a prior period, that write is an operator event with a name on it.

If a number cannot be traced, it does not ship.

That is the whole product. The rest is typesetting.
