A packet's via field names the repeaters that forwarded it and neither the
node that sent it nor the one that heard it, yet its ribbon opened and closed
square, the mark that says the route began and ended there. PathLine takes
from_origin / to_destination: a cleared end opens on the notch or closes on
the point, and arrow mode spells it with a bare leading or trailing arrow.
The packet viewer's via chain and the TX sweep's composed relays draw both
ends open. Under the chain, the "reception describes..." note gives way to
the hop count atom the node page and trace scenarios already carry.
