"description": "The governed execution layer for AI agent commerce. The source catalog describes DeFi adapters and multi-chain paths; current support must be established from route discovery, policy, settlement, and receipt evidence. YieldAgent policy and required operator approval authorize governed actions; x402 applies when the selected route advertises it. Terminal orchestrated outcomes produce sealed receipts, with signing, TEE, settlement, and external-proof labels only when matching evidence is present.",
