G23 Evidence Copilot is a deterministic evidence-verification system designed to help developers distinguish verified results from unknown, mismatched, or corrupted evidence. It uses SHA-256 hashing, hash-chain integrity checks, trusted expected values, and explicit verification states. AI can help explain evidence and verification outcomes, but it cannot override the deterministic verifier. The project focuses on making software claims auditable, reproducible, and limited to what the available evidence actually proves. The current prototype includes automated tests for verification behavior and failure cases.
