• Dynamically discover Group schemas and construct required Group attributes.
• Support required Google Cloud Identity Group email attributes.
• Skip User and Group pagination validation for googleapis.com endpoints.
• Treat externalId as a common SCIM attribute during schema discoverability validation.
• Improve verbose and non-verbose manager PATCH operations.
• Skip provisioning-log verification for manager removal when SCIM confirms removal.
• Safely handle typed attributes when no matching array element is returned.
