 This document specifies Known Value predicates for Fair Witness attestations in Gordian Envelopes. These predicates support human observation and attestation, where a neutral third party observes and attests to facts without advocacy or interpretation.
 
-Fair Witness predicates are distinct from Anchor predicates (BCR-2026-004): anchors provide **cryptographic attestation** to event logs, while Fair Witness predicates support **human observation attestation** with disclosures about independence and perspective.
