Description
Witness is an open-source local prototype for inspectable evidence trails. It separates Observed, Inferred, and Generated records, preserves declared premises and methods, and provides a CLI, REST/GraphQL APIs, and a browser dashboard. Try a disposable synthetic demo. Hashes and signatures help check integrity; they do not establish truth. Built by NextEleven.
