The line at the top holds a start

The road gets named at the top of the work record, and the line goes in before any of the work starts. The finished output carries no trace of it.

A run set off on the full road. The outside check came back with nothing attached, the last stretch was dropped, and the work went out through a door with no name — not the door where dropping is agreed up front, not the door where things get signed off afterwards. The opening line was still right about where the run began, and had quietly stopped being right about where it ended.

The door has a name now. And the line at the top holds a start; it was not built to hold an exit.
