Checks 1–7

FROST threshold signing committee (2-of-3). Three AI agents (Guard, Judge, Steward) independently evaluate proposals and collectively produce a single Schnorr signature verified on-chain at ~5,300 gas constant cost regardless of committee size. No agent holds the private key - it is generated distributedly via DKG and never exists whole. The committee operates within human-delegated ERC-7710 permissions: Uniswap Router only, max 100 USDC, exactInputSingle and approve methods only. Group public key: 0xe9ce73256b6f8f46183b5b6911d54b019809746a. Contract: 0xda9F141BEA3d4472dd4c17c0102d833Ec0202EB4 on Base Sepolia. Guard (index 0) evaluates risk with a 3 USDC threshold. Judge (index 1) enforces delegation policy compliance. Steward (index 2) checks operational viability. Coordination over XMTP E2E encrypted messaging. Protocol: FROST RFC 9591.

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.
