Checks 1–7

Reputation layer for autonomous on-chain agents. Blends four signal tiers — x402 receipts, behavioral evidence, declared identity, social attestation — into a portable Provider + Consumer karma score, plus an orthogonal Autonomy Confidence axis. Non-routing: AK scores wallets, it does not proxy paid calls.

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.
