The /discovery/probe/{protocol}/{scope} address segment for a protocol-WIDE probe — one
with no NIC of its own (ProbeUnavailable.scope absent). A REST path needs a concrete
segment even where the fact itself carries none, and global is the one every probe's own
blindness collapses onto when it is not per-link — never '' or '-', which would read as a
malformed NIC name rather than a deliberate "the whole protocol, no narrower scope".
