- App healer (v7): checks DNS healer every 30s, restarts if down
- DNS healer (v2): checks app healer every 60s, restarts if down
- scripts/watchdog.sh: ultimate fallback cron job (every 5 min)
revives both healers if both are down simultaneously
- Installed to /usr/local/bin/falah-watchdog + /etc/cron.d/falah-watchdog
Three-layer defense:
Layer 1: Docker --restart unless-stopped (instant)
Layer 2: Cross-heal between the two healers (30-60s)
Layer 3: Cron watchdog (5 min, last resort)
