    not checked

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

    not checked — this check was never asked

    This run never reached this check for this agent.

  7. Has feedback?rung 7 · attested

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.
