+Description: 'Creates an IAM Role for Elastic Identity Federation. Grants read-only permissions for all Elastic AWS integrations that support Identity Federation: the AWS package integrations (GuardDuty, Inspector, Config, CloudWatch, and metrics services)'
+
+Parameters:
+  ElasticRoleARN:
+    Description: Elastic's super-role ARN. Change only for test environments.
+    Type: String

+Resources:

+  # Grants live in two places, both mirroring the provider_permissions
+  # declared in each integration's package manifest (elastic/integrations):
+  # managed policies (`roles`) go on the role's ManagedPolicyArns; inline
+  # permissions get one AWS::IAM::Policy resource per federated integration.
+  # Add grants only when an integration gains Federated Identity support —
+  # never ahead of a declaration.
