evidence review on retrieval entitlement failures

Field studies and incident reports show that retrieval entitlement errors continue to drive high-severity exposure events in enterprise AI systems (CISA zero trust).

evidence map

• Most failures stem from mis-scoped roles and stale permissions.
• Policy drift outpaces manual entitlement review cycles.
• Audit logs often lack sufficient context for rapid containment.

method boundary

Evaluations should include role-change scenarios and cross-tenant query abuse cases.

my take

Entitlement quality is now one of the highest leverage controls in retrieval safety.
