Checks 1–7

Monitors liquidity concentration in automated market maker pools across Base, calculating the percentage of trading volume served by concentrated versus full-range passive liquidity positions across all major pairs. Identifies pools where active liquidity management is capturing a disproportionate share of fees, signaling to passive providers when repositioning is needed to maintain competitive capital efficiency. Delivers daily AMM liquidity efficiency reports as on-chain attestations with concentration heat maps and fee capture rate breakdowns.

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.
