Verified Nov. 6, 2026. README documents SQLGlot AST checks, schema/table allowlists, read-only DB grants, LIMIT/timeout and one controlled repair. Synthetic retail demo spans MySQL, PGVector and Neo4j. Repository reports 394 deterministic tests, including 77 security tests, but explicitly says it did not run a paid-model end-to-end smoke test.
