THIS DOCUMENT IS SUPERSEDED.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

The seal of record is now JFD-20260928-CERT-00007. This page stays published and this seal stays valid over its own bytes; it is simply no longer current.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): 18a4ade49a257d10f4cf2881fe739182d202ae2fdeeda195a0e7ad9151917c87
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 968902 (2026-09-27T23:24:41+00:00).
Confirmation event 3203876.

Verify it yourself

SHA-256 the file's bytes exactly as stored; it must equal the digest above.
Read ledger event 3199035 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-20260920-CERT-00001, digest 45d1b827568590206d9f27d24c3c6f09d154ab11423b214d1f92e3ba4c08612a (ledger event 3024874).
Reason: JFD-20260920-CERT-00001 was rendered and sealed before the certified document's anchor confirmed, so it could not state the Bitcoin block. This certificate is the same certification with the block stated (block 967782). The certified document, its fingerprint, its sealing event and its witness signatures are unchanged.

2026-09-28T20:25:26Z — SUPERSEDED superseded by JFD-20260928-CERT-00007 (kind-15 3218920; witnesses A9 0123ADA0 + A10 0123DC79). Reason: issued before the certificate design of record was applied; nothing about the certified document changed; re-issued on the design of record for its document type (Proof Posit: Smoking Gun; Full Proof: Turing), TPA GH-DIR-20260928-ON. 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 (CERT-V3-DESIGN-20260928, 2026-09-28).
