● healthy security-audits

Pre-signature payment-risk oracle for x402 agents: one call returns GO / HOLD / STOP for paying a counterparty — from OFAC sanctions screening, counterparty reputation, and price-anomaly — plus an independently-verifiable Ed25519 signed receipt. Verdict only, never custody; free under $10 at risk, x402-payable above. Remote MCP tool (`forecast_payment`) + npm (`blackwall-mcp`).
