HUMAN JUDGMENT SYSTEMS FOUNDATION This document defines HJS (Human Judgment System), a standalone accountability layer for AI agents. HJS provides four primitives (Judgment/Delegation/Termination/Verification) for recording complete responsibility chains, and uses OTS (Open Timestamp) proofs anchored to the Bitcoin blockchain to create immutable, court- admissible evidence. While HJS can complement other protocols (e.g., AIIP) by providing the evidence they require, it is designed to be independent and usable with any AI agent communication framework.
