- Dockerfile: add HEALTHCHECK (30s interval, 10s timeout, 3 retries) - rate-limit.ts: auto-cleanup stale entries every 5 min (prevents memory leak) - scripts/auto-heal.sh: watchdog for Synology cron — auto-restarts container, reloads nginx gateway, escalates on excessive failures - CI workflow: auto-rollback on deploy failure (tags :rollback image, reverts if health check fails after deploy)
