THIS DOCUMENT IS SUPERSEDED.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

The seal of record is now JFD-20260929-CERT-00001. This page stays published and this seal stays valid over its own bytes; it is simply no longer current.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): d3abda1db13133b7f028ed44d23f95b835a9540298c6796f6e0140699d4ae115
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 3218920 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-20260920-PP-00001, sealing event 3024863, digest b15b75eedd5fb3a3acd64178b994494911cf524fc9e4c145e30970da006841ed. Its verify page.

The certified document is ATTESTED in Bitcoin block 967782 (block hash 0000000000000000000217f5069b04da88efa203711ed83122f7203c89dcc1d1, block time 2026-09-20T02:36:02Z). This certificate was sealed after that anchor confirmed and states it.

Supersession

This version supersedes JFD-20260927-CERT-00002, digest 18a4ade49a257d10f4cf2881fe739182d202ae2fdeeda195a0e7ad9151917c87 (ledger event 3199035).
Reason: JFD-20260927-CERT-00002 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 967782. The certified document, its fingerprint, its sealing event and its witness signatures are unchanged.

2026-09-29T06:43:49Z — SUPERSEDED superseded by JFD-20260929-CERT-00001 (kind-15 3228648; witnesses A9 0123ADA0 + A10 0123DC79). Reason: superseded by the third issue (JFD-20260929-PP-00001): The third issue carries the full text of the second as readable pages with every figure unchanged: the deferred block hash and method hashes stated from the Glass Hull ledger, the re-run hash struck (no ledger record carries it), and the second issue's anchored seal record restated. 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).
