Checks 1–7

Processes social sentiment data aggregated from verified on-chain oracle feeds, then correlates sentiment shifts with historical price action across multiple market cycles to calibrate predictive accuracy. Generates composite fear-and-greed scores for individual tokens updated hourly, distinguishing organic sentiment driven by fundamentals from manufactured noise. Streams sentiment regime change alerts to subscribed agents when readings shift from neutral to extreme zones.

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.
