HAProxy Manager Build and Push / Build-and-Push (push) Successful in 1m11s
haproxy runs as a background child of PID 1 (gunicorn) with nothing watching it after init. If the haproxy master dies mid-life (observed 2026-07-01 on whp01: SIGABRT -> exit 134, reaped by gunicorn and logged as "Worker (pid:22) exited"), the container stays "up", Docker's --restart never fires, and haproxy is down until the external host watchdog full-restarts the whole container minutes later (dropping every connection). Add an in-container supervisor loop in start-up.sh (Phase 1.5) that runs scripts/ensure_haproxy.py every HAPROXY_SUPERVISOR_INTERVAL (default 15s). ensure_haproxy.py calls the existing, idempotent start_haproxy() only when haproxy isn't running (psutil guard), reviving it in place within one interval with no container restart. Same entrypoint-supervision pattern shipped for cac-litespeed. Validated locally: killing haproxy -> revived with new PIDs in ~one interval, container stayed healthy, no spurious restarts while healthy.
