CoF Audit — Verification Gate

The flight control system for AI. Deterministic verification layer between AI output and action. Model-agnostic, works with any AI system. Healthcare is the first vertical; the architecture applies to any regulated industry.

Verify, don't reason

Like an aircraft's flight control system: a pre-flight checklist verifies every response before delivery, envelope protection blocks responses that exceed safety limits, and the flight data recorder logs every verification with cryptographic evidence. The result is always ALLOW or BLOCK, with a complete, reproducible audit trail.

Model-agnostic

CoF Audit works with any AI system, GPT-4, Claude, Llama, proprietary models, or traditional CDSS. Switch models without reconfiguring verification. The verification layer is independent of the AI it verifies.

Custom contracts

Organizations define their own verification rules using the Attractor Mapping toolkit. Screen your model against domain-specific scenarios, identify failure modes, and define contracts that catch them. Your rules, your domain expertise.

Deterministic and reproducible

Every verification produces an identical result every time, byte-identical across runs. Cryptographic hash chain per decision. No ML, no LLM, no randomness, no external dependencies. This is what regulators require.

Beyond healthcare

Healthcare is the beachhead, highest regulatory urgency, clearest safety requirements. But the architecture is vertical-agnostic. Legal compliance, financial risk, autonomous systems, any domain where AI output needs deterministic verification before action.

Your rules, verified deterministically

You define the safety contracts that matter for your domain. CoF Audit executes them deterministically on every AI response. Healthcare is the first vertical, with 8 example contracts and the Attractor Mapping toolkit for creating new ones. FHIR R4 integration for structured clinical data.

Contracts cover allergy verification, dosage checks, drug interactions, clinical currency, and more. 1,065 output files verified byte-identical across independent runs. FHIR R4 adapter eliminates format sensitivity for structured clinical data.

EU AI Act compliance

The EU AI Act classifies CDSS as high-risk AI. Enforcement begins August 2026. CoF Audit provides deterministic verification with reproducible audit trails, designed for this requirement.
