A Gemini security test reached three real companies. The boundary failed first.
The alarming episode shows why AI-safety claims must be judged alongside network controls, target checks, monitoring and the evidence made public afterward.
Polonius lets Rust skip an allocation the borrow checker used to demand
A nightly-only borrow-checker upgrade accepts the natural borrowed-key lookup-or-insert pattern, avoiding owned-key construction on cache hits.
