SummaryAn experimental prototype evaluates authorization propagation in multi-hop Agent2Agent workflows, separating caller context, transitive authority evidence, per-hop Ed25519 authentication, and replay state. It rejects 14 of 15 adversarial cases but reveals missing authority attenuation and a shared-HMAC-key weakness.
Why it mattersThe controlled benchmark gives builders concrete security checks and measured tradeoffs for delegated workflows, while clearly delimiting the prototype’s synthetic healthcare setting.
