AWS connect-decisions documentation change
Summary
File renamed and moved from AWS Supply Chain to Amazon Connect Decisions legacy documentation. Updated PDF links, breadcrumb navigation, and changed 'AWS Supply Chain' to 'Supply Chain' in user email context.
Security assessment
This is a documentation restructuring/migration change. The content remains about user onboarding but is being moved to a different service's documentation set. No new security content is added, and there's no evidence of addressing a specific security vulnerability.
