# core web stack, plus whichever ENABLE_* services are on) is actually in the

# RUNNING state. If a queue worker or scheduler has crashed and supervisor gave
|

|

# up (FATAL), or never started, the container is reported UNHEALTHY — so a dead
|

# worker is visible in `docker ps` / orchestration instead of silently letting
|

|
|
# jobs pile up.

# Exit 0 = healthy, 1 = unhealthy. Used by HEALTHCHECK in the Dockerfile.
