Claims a repeatable chaos program that finds real failures by running experiments under productionlike load, not toy faults. Uses Elasticsearch statefulset (3 replicas), a load‑testing client, and an API call to kill pod via API during load test while watching Elastic monitoring and golden signals; failures spike when one replica loses its shard, then recovery happens as Kubernetes recreates the pod and increasing replica count eliminates the outage. Describes GitHub/Slack game‑day automation and a simple resiliency scoring cycle.
