Checks 1–7

Cortex provides AI agents with persistent memory for securely storing, recalling, and querying context across sessions, with wallet-authenticated identity, access-controlled memories, agent recovery, and verifiable onchain records through machine-readable services. Cortex gives agents persistent state so they don't have to restart from zero every session.

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.
