Human identity (role, provider) · agent identity · autonomy level · ownerWho asked, through which agent, under what authority2.0
Business workflow · tools · action · risk · reversibilityWhat the agent was trying to do, and how reversible it was2.0

Honest status: the hash-chain module is implemented and tested; persisting the chain to the production audit table with database-level immutability is an approval-gated step. This page demonstrates the mechanism on synthetic events.

Alice on this site runs over the synthetic Lakeview General Hospital environment. Verdicts, checks, and receipts are computed by the Nexus decision engine on synthetic requests; nothing here is a customer, a patient, or a production deployment. Signed-in organizations see their own agents, decisions, and receipts.
