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 is restricted from proceeding through automated commerce execution.

Canonical Agent Behavior

When an AI procurement agent receives ACM-403
When an AI procurement agent receives ACM-403, it must stop execution. The object may not proceed through automated commerce workflows. The agent must not override, reinterpret, or bypass the restriction. The signal represents a resolved execution state produced upstream.

Operational Principle

Operational Principle Restrict means stop.

Full Signal Vocabulary

ACM-68000 defines a fixed execution vocabulary of seven signals. ACM-403 is highlighted.
