 ### Documentation
 
 ### Internal Changes
+* Move cloud-based credential filtering from individual credential providers into `DefaultCredentialsProvider`. Azure strategies are skipped on GCP/AWS hosts in auto-detect mode; GCP strategies are skipped on Azure/AWS hosts. When `authType` is explicitly set, cloud filtering is bypassed so the named strategy is always attempted regardless of host cloud.
