Authority to act

Evidence and agent registry

Who can act for the company, and on whose authority. This is what a counterparty's agent checks before it accepts an order, signs, or pays.

Who can authorize an agentNot assessedNo Alpha inference about signing authority or board-reserved matters is published for this record.
Not assessed

AI agents registered by the companyNot registered in the public RegistryAgent Deployments, Agent Use Cases, Authority Grants, TrustChecks, Action Ledger entries and Governance Receipts live in the private enterprise overlay. They are never projected into the public Registry without explicit cross-plane authorization. Absence here is a plane boundary, not evidence that the enterprise operates no agents.
