name: Foreign stack interop

# Runs the interop fixtures of tests/Opc.Ua.Interop.Tests against peers built
# on other OPC UA stacks (tests/Opc.Ua.Interop.Peers/<stack>). The fixtures are
# the same ones the main CI runs against the 1.5.378 peer; the peer is swapped
# through OPCUA_INTEROP_PEER_HOST, OPCUA_INTEROP_PEER_HOST_ARGUMENTS and
# OPCUA_INTEROP_LEGACY_PEER (native peers run without a host). Known defects of
# a stack are listed in its expected-differences.json and reported as
# inconclusive.
#
# Opt-in: nightly, manual, and pull requests labelled 'interop'. It is not a
# required check, so a regression of a foreign stack never blocks a merge.
