    unprobeable

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

    unprobeable — no declared endpoint that a probe can reach

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.
