 ## Overview
 
+**Important**: The STS service uses a **stateless JWT design** where all session information is embedded directly in the JWT token. No external session storage is required.

 The S3 IAM integration tests validate the complete end-to-end functionality of:
 
 - **JWT Authentication**: OIDC token-based authentication with S3 API
 - **Policy Enforcement**: Fine-grained access control for S3 operations
-- **Session Management**: STS session token validation and expiration
+- **Stateless Session Management**: JWT-based session token validation and expiration (no external storage)
 - **Role-Based Access Control (RBAC)**: IAM roles with different permission levels
 - **Bucket Policies**: Resource-based access control integration
 - **Multipart Upload IAM**: Policy enforcement for multipart operations
