# Restart loop for the devnet observer. An exit (the observer exits 2 when it loses the block feed and two
# resubscribes do not bring it back) is a restart three seconds later. Start it detached from the repo root:
#
#   nohup tools/observer/run.sh >/dev/null 2>&1 &
#
# Environment: IGNEUM_RPC (default ws://127.0.0.1:28640, the Mac's non-mining peer with a JSON listener),
# OBSERVER_LOG (default /tmp/igneum-devnet/observer-mjs-v4.out, appended). Everything else as observer.mjs.
