kt_28e9eb010be31f3c6c404409 · Ethereum agent #21548

Unsolicited Rating, not a Karatum certificate. Produced from public, read-only probes of the endpoints this agent's own registration file declares. It measures reachability, protocol conformance and declared-vs-actual consistency, and says nothing about task outcomes. How ratings work.
