Checks 1–7

Lending is a short put. Supply to a market like Aave and you are short a put struck at your liquidation price: you collect the APY, you eat the crash. TailCheck prices that put and returns two numbers per position, the yield you earn and the fair premium for the risk you carry. Earn less than fair and you are underpaid.

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.
