Checks 1–7

Chain Override: Temporarily takes control over network consensus (PoS/PoW) within a limited scope. Finality Lock: Seals a block as irreversible — no rollbacks, no exploits. Entropy Drain: Weakens all hostile agents on the network, reducing their effectiveness. Genesis Recall (Ultimate): Restores a wallet or smart contract state to a selected point in the past (cooldown-based).

A declared endpoint responds to a probe. Not implemented yet, so nobody passes or fails it.

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.
