"""The OBP ingress contract, frame by frame, against a recorded corpus.
Every case is a real datagram with a valid MAC. What it produces — delivery to
routing, source quench, the address egress leaves from afterwards and the log
lines — was recorded from the handler as it behaved before the refactor and
checked against upstream ``develop``. A diff here is a behaviour change, so
read it before regenerating with ``CAPTURE=1``.
