Checks 1–7

Agents now read mailboxes and act on what they find, and nothing checks if the message is from who it claims. Envelope verifies inbound mail cryptographically: DKIM signatures, SPF, DMARC policy and identifier alignment, ARC chains for forwarded mail, display-name and lookalike-domain spoofing, header-chain forensics, and the structural risk of attachments and links without ever opening or fetching them. It proves who sent a message, never that the message is safe. Ten paid tools, eight free.

    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.
