Monitors Vitess shard health and alerts when live topology drifts from a declared desired topology. Validates that shard key ranges tile the key space, tracks replication lag, throttler state, scatter-query ratio and reparent flapping. Ships a self-contained web dashboard, a Prometheus /metrics endpoint, and a CI-friendly CLI.
