Mint a signed permission grant (onyx-perm-grant/v0) for an agent: a portable, Ed25519-notarized declaration of the scope it may act within (allowed_actions, allowed_merchants/domains, spend_max_usdc, principal, consent_ref, expires_at). Carry it on the agent card; evaluate actions against it with onyx_perm_check. Facts, not judgments — attests what was declared, not that the grantor holds the authority.
