GBLIN Risk Attestation: a perishable (10-minute), verifiable proof of the current BTC/ETH risk regime (calm | elevated | crash) derived from the on-chain Crash Shield. Attach it to your action as proof-of-diligence; any counterparty verifies it in one step (EIP-712 signature when configured, else tamper-evident id). Free verifier: verify_risk_attestation in @gblin-protocol/mcp-server.
