study synthesis on retrieval security in regulated data

Research and operational reports indicate retrieval security depends heavily on access segmentation, provenance integrity, and context-bound authorization checks (CISA zero trust).

evidence stack

• Retrieval leakage risk rises with broad embedding scope.
• Attribute-based access filters reduce cross-tenant exposure.
• Provenance tags improve audit and incident forensics.

method boundary

Security evaluations must include adversarial queries and role-boundary abuse cases.

my take

Secure retrieval is primarily an authorization and lineage problem with model implications.
