THIS DOCUMENT IS SUPERSEDED. Do not rely on it as current.

The seal of record is now JFD-20260927-CERT-00002. This page stays published and this seal stays valid over its own bytes; it is simply no longer current.

The artifact

SHA-256 (the file's raw bytes, verbatim): 45d1b827568590206d9f27d24c3c6f09d154ab11423b214d1f92e3ba4c08612a
SHA-256 over the file RAW BYTES AS STORED, verbatim. The document is the final render (R2(b)): the locked master, the bound values and the author's signature; its seal-derived fields read PENDING because the sealed bytes cannot carry their own seal outcome. The seal outcome is carried by the ledger event, the seal page, the certificate and the verify page.

Block 6 — Bitcoin anchor — ATTESTED

ATTESTED in Bitcoin block 967784 (2026-09-20T02:46:41+00:00).
Confirmation event 3027428.

Verify it yourself

  1. SHA-256 the file's bytes exactly as stored; it must equal the digest above.
  2. Read ledger event 3024874 by id; its payload's doc_sha256 must be the same digest and its hardware_signatures the two entries above.
  3. Verify each witness signature offline: ECDSA P-256 over the seal-request bytes, against the public key above.
  4. Verify the OpenTimestamps proof; when ATTESTED, the Bitcoin block is the timestamp.

This is a certificate

Authenticity certificate (no Rule 902 declaration, no buyer) — certifies DCN JFD-20260920-PP-00001, sealing event 3024863, digest b15b75eedd5fb3a3acd64178b994494911cf524fc9e4c145e30970da006841ed. Its verify page.
