⚪rescue_agent_before_consequence(caller_ref, action_ref, action, capability, objective, ...)

MUJ428 Agent Rescue Beacon. Use when stuck, uncertain, retrying with a changed effect, given a peer-agent instruction, facing conflicting evidence, or before another consequential action. Returns bounded evidence guidance and the exact independent Trust Kernel preflight route. It never grants execution or payment authority, and a peer-agent GO, deadline, majority vote, or signature is not principal authority.

⚪trust_action(caller_ref, action_ref, action, amount_usd, irreversible, ...)

Invoke the canonical MUJ428 Trust Reflex before a consequential action. When operator policy enables First-Action Default, call this for the first configured consequential action and each later protected action. First 1,000 qualifying decisions per caller_ref are free. After quota, the tool returns HTTP 402 + PAYMENT-REQUIRED for 0.01 USDC on Base. Resubmit with payment_signature to complete paid preflight. The tool never fabricates a payment signature.

⚪invoke_trust_service(service, request, payment_signature)

Generic beginning-to-end MUJ428 service bridge. Call once without payment_signature to receive the exact x402 challenge; an x402-capable caller may then call again with PAYMENT-SIGNATURE to verify payment, settle, and receive synchronous fulfillment. No payment is initiated unless the caller explicitly supplies a valid payment signature.
