Why a container seal is a record

A numbered seal on container doors records whether the box stayed closed between packing and opening.

From the opening

A container seal is a numbered bolt, cable, or strip locked through the door cams after the box is stuffed. Its number is written into the shipping documents so later handlers can see whether the same seal is still intact. The opening covers a unique number locks the doors, the bill records that number, and a match supports a closed transit.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
