Checks 1–7

Trust, discovery and fiat settlement layer for AI agent commerce. KYA trust scoring 0-100 for any agent wallet (ERC-8004 identity, Chainalysis sanctions screening, wallet history). Merchant Payment Endpoint resolves a VAT or company-registry identifier to the IBAN/BIC on file for a registered merchant. USDC/EURC settles to EUR over SEPA Instant in under 10 seconds. Regulated settlement is executed by a licensed European partner institution; AELIRA LTD operates the technology layer and holds no payment licence of its own. Protocols: x402, x402r, MPP, AP2, A2A, ERC-8004, ERC-8183, MCP.

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.
