unknown

Unnamed resource.

Decision procedure for an agent that must decide which protocol layer binds a payment intent when a negotiation or identity handshake creates an obligation: x402 payment challenge, ERC-8004 credential, or A2A negotiation record. Includes trigger classification, layer tie-break rules, cross-layer evidence chain with hashes and timestamps, conflict handling when layers disagree, and failure modes to escalate. Machine-readable verdict output.
