🔗 Solana Attestation

Why blockchain for NEPA? How SHA-256 of scan results get written to devnet via SPL Memo — and how anyone can verify without trusting our backend.

🚨 Compliance Signals

All 8 risk flags — deferred mitigation, EJ analysis gaps, no-action alternative quality, tribal interests. Regex-based, testable, auditable, with process-type gating.
