What helps us reply well

Bring the action, the policy and the evidence need.

For agentic payments: tell us what the agent can buy, the maximum spend, who holds consent and where the payment provider sits.

For verification checks: tell us the source record, what yes or no means, and what downstream system consumes the result.

For audit: tell us whether you need ML-DSA-65 attestation, Merkle evidence, webhook delivery or export into your own logs.
