ACM-451
ESCALATE

Signal definition node for the ACM-68000 protocol. This node defines the ACM-451 signal. It does not issue signals, resolve transactions, or execute actions.

Signal Definition
Human review required. Automated resolution not possible.
Semantics: The resolver cannot make a deterministic decision. The transaction must be escalated to human review.

Action: escalate_to_human()
Deterministic: true
Reversible: false
Constraints

What this
node does not do.

This is a signal definition surface. It documents the meaning of ACM-451. All actual signal issuance flows through the resolver.

Resolver
Dependency

ACM-451 signals are issued exclusively by the canonical resolver. This node documents the signal — it does not produce it.
