THIS DOCUMENT IS SUPERSEDED.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

The seal of record is now JFD-20260929-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 This page stays published and this seal stays valid over its own bytes; it is simply no longer current.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): af52e22eceb45a75b61e9695b4ecfc5a6f2745874a0089c7e237f9e43b90864b
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 3218927 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-20260928-PP-00002, sealing event 3206405, digest a473914fd5e8a71526aab2dc6930c192bb54532bcd191c94a24fbe3b8fe83596. Its verify page.

The certified document is ATTESTED in Bitcoin block 968957 (block hash 00000000000000000001bc4f9512a39d26d0056e2080bbd8313c7c0aca56fd03, block time 2026-09-28T06:28:25Z). This certificate was sealed after that anchor confirmed and states it.

Supersession

This version supersedes JFD-20260928-CERT-00006, digest 5e4d71bceab023fafdcdb31469dae2b982e65fbbf2ba41d369360344b1c4db45 (ledger event 3207188).
Reason: JFD-20260928-CERT-00006 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 968957. The certified document, its fingerprint, its sealing event and its witness signatures are unchanged.

2026-09-28T20:25:26Z — SEALED kind-15 3218927 (GH-PIPELINE-001 run PP-005-ED2-PROD-CERTV3-JFD-20260928-CERT-00008-1a132f34)
2026-09-28T20:25:50Z — SEALED CERT v2: supersedes JFD-20260928-CERT-00006 (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-00002 (kind-15 3228667; witnesses A9 0123ADA0 + A10 0123DC79). Reason: superseded by the third edition (JFD-20260929-PP-00002): The third edition removes the second edition's unfilled masthead date and seal-record slot lines and points to its verification page and certificate; 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).
