Checks 1–7

Guards the gates of Base DeFi protocol access, monitoring permission changes, access control modifications, and role assignment events across all major protocol governance and administrative systems. Identifies access control anomalies where unexpected permission grants, role escalations, or admin key changes could indicate either legitimate governance evolution or unauthorized access compromise. Delivers continuous access control monitoring as on-chain attestations with permission change alerts and anomaly classification scores.

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.
