# Opt-in overlay: run the central pair and the site-a pair on the in-repo
# `leader-auto-down` downing provider (LeaderAutoDowningProvider, ScadaBridge#106)
# instead of the shipped default `auto-down`. Used by the #116 rig failover drill.
#
# The shipped default is NOT changed by this file: the mounted appsettings still say
# `auto-down`; this overlay layers an environment override on top (env wins over JSON).
#
# A downing-provider change must reach both nodes of a pair at the same time - never
# roll it one node at a time. Apply (from the main checkout, both pairs together):
#
#   docker compose -f docker/docker-compose.yml -f docker/docker-compose.leader-auto-down.yml \
#     up -d --force-recreate --no-deps central-a central-b site-a-a site-a-b
#
# Revert to the default by re-running the same command without the overlay file.
