Checks 1–7

DenScope Verifier is an ERC-8004 agent trust service on Celo that interprets agent identity, feedback, and activity signals to produce a live trust score, risk label, and portable Trust Certificate. It helps users, apps, and autonomous workflows verify whether an onchain agent is trustworthy in seconds, while also exposing the same trust data programmatically through the DenScope trust infrastructure and SDK.

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.
