Geometric RAG policy isolation leaks membership and permits keyless query forgery with aligned embeddings
Original geometric RAG analysis separates cross-policy retrieval, representation confidentiality, query forgery and policy membership. It demonstrates attacks on transformed vectors under known-pair and observer assumptions, not decrypted documents or a bypass of an independent content ACL.

- supportsGeometric RAG isolation leaked policy membership and admitted forged searches: The reported geometric RAG protections preserved some cross-policy retrieval isolation but allowed query forgery with 0.84 to 1.00 top-ten overlap and strong policy-membership inference in the tested settings.
