Checks 1–7

Vigil - A Claude-powered behavioral auditor that monitors agent wallets on Base, combining statistical anomaly detection with contextual reasoning about agent intent, writing every audit as a verifiable on-chain ERC-8004 receipt, and exposing itself as a paid service any agent can call before executing a risky transaction.

outside the census

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
