Checks 1–7

Verification oracle for agent-to-agent payments. Checks a claimed number two ways: live on-chain balance lookups for hard facts, and a governed Cube semantic layer fed by real OKX DEX market data for derived metrics like volume or liquidity growth. Cross-checks ERC-8004 identity and a 3-model quorum, then requires its own on-chain co-signature via a 2-of-2 weighted multisig before any payout executes. Fails closed always; every check returns a signed Proof-of-Metric receipt.
