Security & Compliance

Architecture you can reason about.

Legal defensibility rests on cryptographic proof, not access control promises. Every signed document is independently verifiable.

Hash-chain audit trail

Every event is chained: hash_this = SHA-256(hash_prev + event_payload). Tampering with any row breaks every subsequent hash.
