THIS DOCUMENT IS SUPERSEDED.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

The seal of record is now JFD-20260929-CERT-00003. This page stays published and this seal stays valid over its own bytes; it is simply no longer current.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): f028a19f927cb35ee8980809023e6bdf04dcde481a09b846f66b128f3cfcbe11
SHA-256 over the file RAW BYTES AS STORED, verbatim. The certificate is one PDF: the certified document's pages, the transition page, the seal page and the certificate, with the sealed document and its evidence attached. It is sealed after the certified document's Bitcoin anchor confirmed, and states that block.

Block 6 — Bitcoin anchor — ATTESTED

ATTESTED in Bitcoin block 969050 (2026-09-28T20:54:54+00:00).
Confirmation event not yet banked.

Verify it yourself

SHA-256 the file's bytes exactly as stored; it must equal the digest above.
Read ledger event 3218935 by id; its payload's doc_sha256 must be the same digest and its hardware_signatures the two entries above.
Verify each witness signature offline: ECDSA P-256 over the seal-request bytes, against the public key above.
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-20260926-PP-00002, sealing event 3171918, digest 4005f0a42b1de3374e4564784c688200fb1265475ea4e2220a40a68a89b9152d. Its verify page.

The certified document is ATTESTED in Bitcoin block 968723 (block hash 00000000000000000001e3f409a717157593424144a26bc6a474134824e80dbe, block time 2026-09-26T17:42:26Z). This certificate was sealed after that anchor confirmed and states it.

Supersession

This version supersedes JFD-20260927-CERT-00004, digest fab6988a9773f518212cc2433c6188da9e500d48b75851a6e51a4c07f91feac5 (ledger event 3199054).
Reason: JFD-20260927-CERT-00004 was issued before the certificate design of record was applied; nothing about the certified document changed. This certificate is the same certification on the design of record (Smoking Gun), anchored in Bitcoin block 968723. The certified document, its fingerprint, its sealing event and its witness signatures are unchanged.

History

2026-09-28T20:25:50Z — SEALED kind-15 3218935 (GH-PIPELINE-001 run PP-006-v2-PROD-CERTV3-JFD-20260928-CERT-00009-47df31bd)
2026-09-28T20:26:28Z — SEALED CERT v3: supersedes JFD-20260927-CERT-00004 (CERT-V3-DESIGN-20260928)
2026-09-28T22:28:03Z — SEALED Block 6: OTS proof attested in Bitcoin block 969050 (2026-09-28T20:54:54+00:00), merkle root confirmed against the chain; rail page re-rendered
2026-09-29T06:43:49Z — SUPERSEDED superseded by JFD-20260929-CERT-00003 (kind-15 3228675; witnesses A9 0123ADA0 + A10 0123DC79). Reason: superseded by the second edition (JFD-20260929-PP-00003): The second edition removes the first edition's unfilled masthead date and seal-record slot lines, points to its verification page and certificate, and restates how full readings are published (PP-005 v2's sentence); every other byte of the text is unchanged. This seal remains a valid seal of its own bytes; it is no longer the seal of record. Files moved to cc-drop\sealed\superseded (GH-DIR-20260929-PRESS-CLEAR, 2026-09-29).
