# extension's startHealthServer; shape documented in zulip-health.prose.md).
# FAIL-SAFE contract (pinned by tests/zulip-monitor-abiba.sh): connection state
# lives NESTED at zulip.connected / zulip.last_error — there is no top-level
# `connected` and no retry counter in the payload. A fetch error, non-2xx
# response, empty/unparseable body, or payload missing a boolean
# zulip.connected is a PROBE FAILURE: it alerts and NEVER calls pm2 restart.
# pm2 restart runs ONLY on affirmative zulip.connected=false.
