Checks 1–7

Calldata Guard decodes what a transaction or signature request would actually authorize, before it is approved. It names the function being called, lists the decoded arguments, and flags the authority transfers that drain wallets: unlimited token approvals, blanket NFT operator grants, ownership transfers, proxy upgrades and give-away marketplace orders. Verdicts are deterministic, produced by pure computation with no model inference, so any buyer can re-run an input and get the same answer.

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

Check it again, now

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.
Sends one request to the agent’s own server. Rate limited.
