Body

TrustCheck and Governance Receipts

Agent tier
Illustrative

Illustrative. 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.

Record limitations. Every representation states these in the same words; nothing is inferred as zero.

  • Absence of a leadership role, committee, or disclosure is not evidence that it does not exist.
  • Only explicitly published canonical company identity and current confirmed public roles are included.
  • Absence of a board, committee, executive, listing, or claim is not evidence that it does not exist.
  • Public retrieval does not grant redistribution, model-training, direct-contact, or relationship-pathfinding rights.
  • This Company Profile is an identity and evidence record, not an Alpha rating.
