THIS DOCUMENT IS SUPERSEDED.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

The seal of record is now JFD-20260928-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 This page stays published and this seal stays valid over its own bytes; it is simply no longer current.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): c43432c3156a0fdadbb4bd2539812cd9ff4f9302c9981892e3f46cb66126376e
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.
File: JFD-20260927-CERT-00007.pdf · 8635008 bytes.

Artifact class: resolved (READER/SUBJECT ruling v2, ledger kind-3 3094252; the class is fixed at birth and immutable after seal).

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 3199076 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-FP-00002, sealing event 3173079, digest 855359021b1d998536306042fd7f8b88c5687539d572baf12161c89a7540073f. Its verify page.

The certified document is ATTESTED in Bitcoin block 968728 (block hash 000000000000000000018f3b21e9d9a1a973e16c5f65482448355f4874c9a40f, block time 2026-09-26T18:34:59Z). This certificate was sealed after that anchor confirmed and states it.

Supersession

This version supersedes JFD-20260926-CERT-00005, digest 810553131fdc2ce1d002b9a0be06fc05d4f4b996d492176fe8dbb9a831518c8f (ledger event 3173086).
Reason: JFD-20260926-CERT-00005 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 968728). The certified document, its fingerprint, its sealing event and its witness signatures are unchanged.

2026-09-28T06:52:26Z — SUPERSEDED superseded by JFD-20260928-CERT-00003 (kind-15 3206933; witnesses A9 0123ADA0 + A10 0123DC79). Reason: superseded by version 2 (JFD-20260928-FP-00002): Version 2 sets out the same records in ten parts, prints its full text as readable pages and adds no measurement. 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-20260927-GATE, 2026-09-28).
