…stgres Adds a new `k8s/` directory containing deployable manifests for every runtime component of the platform: - Namespace + ResourceQuota (`00-namespace.yaml`) - Postgres StatefulSet with PVC and a ConfigMap-loaded init script from `database/schema.sql` (`10-postgres.yaml`) - API Deployment, Service, ConfigMap and Secret template (`20-api.yaml`) - Next.js App Deployment, Service and ConfigMap (`30-app.yaml`) - Stream-processing worker Deployment, Service and ConfigMap (`40-processing.yaml`) - Ingress routing external traffic to app + api (`60-ingress.yaml`) - Kustomize entrypoint (`kustomization.yaml`) and a deployment README (`README.md`). To support kubelet liveness/readiness probes the API gains a /livez route that does not touch the database (liveness must never trigger a restart loop on a transient DB outage). The processing worker exposes /livez (always 200) and /healthz (503 once shutdown begins) on the existing metrics server, and that server is now wired into the worker startup and GracefulShutdown so the listening socket is closed promptly on SIGTERM. The Next.js app gains a lightweight /api/health route that bypasses the project middleware. Probes, resource requests/limits, and ConfigMap vs Secret separation all map to issue XStreamRollz#217's acceptance criteria. Closes XStreamRollz#217

There was a problem hiding this comment.
Big +1 from me. Decoupling liveness (/livez) from readiness (/healthz) is exactly right — prevents restart loops on transient DB blips. GracefulShutdown drain + 503 in healthz is nice. README walkthrough is helpful. README clearly documents the CHANGEME-* secrets — please remember to replace them before any non-dev apply 🚢
