DAG attestation walkthrough
See how a signed chain gates a payment capability.
This page renders two fixed states from the SDK example. It does not sign or verify in the browser and it sends no payment. The runnable example creates a 3-agent receipt DAG and gates the payment agent's ADMIN capability on an unbroken chain (composite trust ≥ 0.82, depth ≥ 2).

The fixed browser fixture contains step, capability, trust, and truncated hash metadata, but no signatures or public key. Reproduce the real cryptographic path locally with

npm run demo:attestation in @agentguard-run/spend. That example generates a customer-runtime key, signs complete DAG nodes, verifies them, and calls the capability gate. It does not call a payment provider. The signer rejects named data-plane fields and email-shaped values; integrators must keep any other personal data out of metadata.
