QWED Protocol: Deterministic Verification for Large Language Models

QWED (Query with Evidence & Determinism) is a deterministic verification protocol that treats LLMs as untrusted translators. It validates AI outputs using 8 specialized engines: math (SymPy), logic (Z3), code security (AST), SQL (SQLGlot), statistics, fact checking, image validation, and consensus. In benchmarks against Claude Opus 4.5, QWED achieved 100% error detection where the model had 73-85% accuracy. Open source under Apache 2.0.
