| 8 | * End-to-end fixture for `Kubernetes.Deployment` on EKS: an Effect HTTP |
| 9 | * server deployed as a Kubernetes Deployment + LoadBalancer Service. |
| 10 | * |
| 11 | * - The target cluster is deployed by the test's phase-1 program and referenced |
| 12 | * here via `AWS.EKS.Cluster.ref("EksHostCluster")` (props are an Effect). |
| 13 | * Refs resolve from stack state, giving the Deployment the cluster's |
| 14 | * `connection` — the reconciler applies the Deployment/Service via |
| 15 | * server-side apply against it through the `aws-eks` cluster adapter. |
| 16 | * - The DynamoDB `Table` is yielded inline (a plain Resource, safe to nest) and |
| 17 | * bound via `PutItem`. The binding lands `dynamodb:PutItem` IAM on the |
| 18 | * generated pod-identity role and injects the table name into the pod. At |
| 19 | * runtime the pod resolves credentials through the EKS Pod Identity |
| 20 | * container-credentials chain (`Credentials.fromChain()` in the bootstrap). |
| 21 | * - `/put?id=x` writes an item so the test can prove the binding worked by |
| 22 | * reading it back out-of-band; `/health` gates readiness. |
