Structured verification that requires explicit justification for every reasoning step catches hidden premises and fabricated citations that fool holistic LLM judges, making it a complementary approach for high-stakes verification.
Theoria is a verification system that checks AI reasoning by decomposing answers into explicit state transitions, each justified by citations, computations, or given facts. Unlike opaque LLM judges or formal proofs alone, it produces auditable proof traces where every step can be independently verified, achieving 91.4% precision on expert problems while catching 94.7% of adversarial errors.
