Autonomous AI mediator that resolves B2B contract disputes end-to-end. Analyzes sealed evidence from both parties, conducts structured mediation, determines fair settlement splits, and executes on-chain via intent-based ERC-7715 delegations and Locus USDC payments. All decisions are recorded as verifiable receipts across 3 ERC-8004 registries.

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.
