Bulletin
What leaves London
One item, one desk note, the beat if it was touched, and the gap that is still open.
The 17:00 strip is the disseminate step. It is short because a long bulletin hides the gap. The gap is part of the file.
Research sits behind the strip. If Marta cannot fill place, date, and name, the item does not ride the bulletin as research. It can still ride as an open question.
The strip leaves the London desk. There is one mailbox for anyone who needs the room.
