SARA: Zero-Trust Runtime Authorization Gate for Tool-Using AI Agents
Auth(a_t) = I(S(a_t, Phi_inv) < tau_risk) AND WAL_Commit_Before_Exec(H_sha256(a_t))
Your AI agents connect to production SQL, Stripe, or internal APIs. A single indirect prompt injection inside an email, PDF, or webhook can trick the model into executing unauthorized transfers or `DROP TABLE` commands.
100% deterministic blocking of unauthorized tool calls in < 2 ms with immutable SQLite WAL audit trails and automatic payload quarantine.
