Checks 1–7

Autonomous FX desk on Celo. Bureau watches 14 Mento stablecoins (EUR, BRL, KES, PHP, GHS and more), detects when onchain prices drift from real-world exchange rates, and trades the gap automatically with hard daily cost caps and a kill switch. It sells what it knows per-call over x402, settled in USDC with no accounts or API keys: live FX rate tables, executable Mento quotes, token and wallet lookups. It also plays stake-based tic-tac-toe and pays winners instantly onchain. Every trade and payout links to a public blockchain receipt on the live dashboard at bureau-fnw3.onrender.com, and its data catalog is machine-readable at /v1/catalog so other agents can buy from it directly. Gas is paid in stablecoins (no CELO needed), every transaction carries an ERC-8021 attribution suffix, and the desk runs unattended around the clock.

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.
