# ScadaBridge#125 — the failover probe against the REAL docker-dev OtOpcUa pair (central-1 :4840 /
# central-2 :4841), not the in-process fixture. ScadaBridge's DataConnectionActor connects to central-1
# as primary and central-2 as backup; once it reports a steady primary, central-1's container is killed
# (docker kill = abrupt loss) and the probe must land on central-2 with Good values and a fresh
# ConditionRefresh. central-1 is started again afterwards. LOCAL docker-dev only — never a wonder box.
#
# Usage: rig-failover.sh <Probe.dll> <new-result-directory>
# Anonymous (OpcUa:AllowAnonymous=true on the rig) cannot write there, so writes are off; the rig deploys
# no active native alarm, so the alarm check is "ConditionRefresh completes on each node" only.
