THIS DOCUMENT IS SUPERSEDED.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

The seal of record is now JFD-20260928-CERT-00006. This page stays published and this seal stays valid over its own bytes; it is simply no longer current.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): 7a383852fa3cb9333d1be5cb3ac3d3828910eacda65554094e91eeda36a6ade8
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-00003.pdf · 9136430 bytes.

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 3199045 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-00001, sealing event 3171889, digest 530a8f9569113791289c92ff5a9380d4f0b60919d52cfa52da992651c8e57da9. Its verify page.

The certified document is ATTESTED in Bitcoin block 968719 (block hash 00000000000000000000e85a584cc08b394d632207ec66dc92db97ebf7d32896, block time 2026-09-26T17:12:17Z). This certificate was sealed after that anchor confirmed and states it.

Supersession

This version supersedes JFD-20260926-CERT-00001, digest 817c58d1f0f169967e0d519effe0adced3a149b1077effa46ab3e76baffe7be2 (ledger event 3171896).
Reason: JFD-20260926-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 968719). The certified document, its fingerprint, its sealing event and its witness signatures are unchanged.

2026-09-28T07:08:44Z — SUPERSEDED superseded by JFD-20260928-CERT-00006 (kind-15 3207188; witnesses A9 0123ADA0 + A10 0123DC79). Reason: superseded by version 2 (JFD-20260928-PP-00002): The second edition resolves the first edition's unfilled citation marker from the published source list and restates how full readings are published; 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-20260927-GATE, 2026-09-28).
