That only works if the policy is globally accessible and authenticated.\n- Auditability/attestation: You can optionally anchor hashes of accepted prompts/executions on-chain for third\u2011party verification later.\n- Interop: Multiple agents, UIs, and services can coordinate around one canonical policy without bespoke integrations.",
