Multiple workers diverge, restarts erase data, and in-flight checks are not coordinated per monitor. Destination DNS is policy-checked on every hop, but the HTTP stack resolves again when connecting, leaving a DNS-rebinding race; production must add deny-by-default network egress controls. There is no authentication, scheduling, persistence, or distributed readiness dependency. +Storage is process-local and volatile. One worker is mandatory; restart loses data and replicas do not coordinate. Docker is configured accordingly.
