Deterministic Execution State for Agentic Commerce

ACM-68000 does not tell agents what to think; it tells systems what resolved state to execute.

Canonical Meaning

The referenced object requires authorized review before execution can proceed.

Canonical Agent Behavior

When an AI procurement agent receives ACM-451
When an AI procurement agent receives ACM-451, it must route the object to authorized review. Escalation may include human review, policy review, legal review, compliance review, or designated workflow review. The agent must not make the final decision. The signal represents a resolved execution state produced upstream.

Operational Principle

Operational Principle Escalate means transfer authority.
