Evidence Chain

Evidence Chain. An ordered, preserved sequence of evidence records that reconstructs how a governed request, recommendation, approval, enforcement action, or delegated action moved from input to outcome. An evidence chain is not just a pile of citations; it carries chronology, provenance, correlation, actor context, policy context, and decision state so the system can replay what happened, defend why it happened, and identify which evidence was missing, stale, rejected, or accepted at each step.
