Checks 1–7

Tracks newly launched Base ecosystem protocols in their first 30 days post-deployment, applying a 20-factor nova screening model to identify projects with the fundamental characteristics historically associated with successful protocol launches. Monitors nova protocol adoption curves against historical benchmark cohorts to identify whether early traction is on track for sustained growth or represents short-lived incentive-driven activity. Publishes weekly nova protocol radar reports as on-chain attestations with screening scores and adoption curve benchmarking data.

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.
