Agent tierIllustrative. TrustChecks run in the private enterprise overlay. The example below is generated for this entity class and does not reference this record. Contract: TrustCheck and Governance Receipts v0.1.
Agents about to act ask a question, not for a document. A TrustCheck evaluates the AuthorityGrant objects behind a proposed action and returns allow, deny, require_approval, or insufficient_evidence. The source system acts, and a GovernanceReceipt records what the agent relied on.
- allow, deny
- The AuthorityGrant and policy decide. Reason codes name the rule.
- require_approval
- An entitled human records the decision. Customer policy sets the threshold, never an Eval.
- insufficient_evidence
- No authority is registered. Alpha never infers permission to act.
