Summary: Execute Dry Run to Verify AWS OIDC Authentication Description: Run a test execution of the updated pipeline to verify that the OIDC handshake is successful and the correct IAM role is assumed. This validates the removal of long-lived access keys.

Tasks:

• Add a temporary debugging step (or use a dry-run script) to run aws sts get-caller-identity.

• Trigger the workflow manually or via a test branch push.

• Analyze the build logs to confirm the connection succeeded without Access Key ID/Secret Access Key inputs.

• Verify the output ARN matches the expected Role ARN.

Acceptance Criteria:

• [ ] The workflow completes the "Configure AWS Credentials" step successfully.

• [ ] aws sts get-caller-identity returns the expected assumed-role ARN.

• [ ] Build logs confirm no legacy environment variables (AWS_ACCESS_KEY_ID) are being used.
