ZTR — Temporal Registry

ZTR creates contemporaneous records of human verification for AI-assisted documents. When a professional reviews a document before filing, submitting, or approving it, ZTR hashes the document (SHA-256), timestamps the professional's declaration via an eIDAS-qualified TSA (Aruba PEC S.p.A.), and returns a retrievable receipt with HMAC integrity seal. The document is immediately discarded — never stored or transmitted beyond the hash. Receipts can be downloaded as professional PDF reports with QR codes for independent third-party verification.
