One check for every agent the organization runs
Nexus is where you build them. Gateway is where you govern the ones already running. ADAP is the open protocol.
Hardalion is the house. Nexus is where you build agents you can let act. Gateway is where you govern the agents the organization already runs.
The check is the same. Allow. A person. Or stop.
ADAP, the Agent Delegated Authority Protocol, is published as an open draft. Apache 2.0. You do not need a Hardalion product to read it.
If the check says no, the action does not happen.
