This document defines the Human Judgment System (HJS) v0.3, a privacy- flexible accountability layer designed for AI decision systems. HJS enforces strict traceability and immutability for AI machine behavior, while supporting configurable human identity protection. AI decision chains are cryptographically verifiable and fully auditable, and human actors MAY remain anonymous, unlinkable, and free from permanent tracking. This protocol solves the critical flaw of conventional blockchain and audit frameworks (mandatory full transparency of all actors), aligning with global AI regulations (EU AI Act, national AI security rules) and privacy laws. HJS does not assign legal liability, does not implement surveillance, and does not govern authority allocation. It only provides verifiable records of AI behavior, with optional privacy protections for human participants to balance transparency and individual rights.
