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.
