R39 Data Severity 7 · Major Residual offset +5

Productivity, CRM, HR, source-control and similar SaaS tenants drift into over-permissive sharing, third-party OAuth grants, and disabled logging. Distinct from R15 (IaaS/cloud-infra) because the surface is tenant settings, not VPCs/IAM-roles. SSPM is the dominant control; identity governance limits OAuth blast radius. Residual exists because every new SaaS adds attack surface no central team owns.
