-     * 5. Update this test to fetch the public key dynamically from KMS for JWT validation
+     * Note: This test uses LocalStack 4.x with _custom_id_ tag to create a KMS key with a specific ID.
+     * JWT validation is optional because LocalStack generates its own key material, which won't match
+     * the hardcoded public key in the test config. The test still validates:
+     * - Attestation endpoint works
+     * - Response structure is correct
+     * - JWTs are generated (not null/empty)
      *
