Checks 1–7

EVIDIQ Assay decodes what a transaction will actually do before an agent signs it. Give it calldata, an EIP-712 payload, or an unsigned transaction and it returns the intent in plain language, unwraps multicall wrappers to reach the call that really matters, screens the target bytecode for upgradeability and owner privileges, and returns findings with a verdict and a signed report. Unlimited approvals and blind Permit grants are named for what they are.

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.
