THIS DOCUMENT IS SUPERSEDED.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

The seal of record is now JFD-20260927-CERT-00004. This page stays published and this seal stays valid over its own bytes; it is simply no longer current.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): 68fd98be10a70f3713296fafc907ceb3b587d2c21218208a6d4918b1d2fa5f95
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 968723 (2026-09-26T17:42:26+00:00).
Confirmation event 3184270.

Verify it yourself

SHA-256 the file's bytes exactly as stored; it must equal the digest above.
Read ledger event 3171925 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-00002, sealing event 3171918, digest 4005f0a42b1de3374e4564784c688200fb1265475ea4e2220a40a68a89b9152d. Its verify page.

History

2026-09-26T17:08:40Z — SEALED kind-15 3171925 (GH-PIPELINE-001 run PP-006-v2-PROD-20260926T170840Z-ac1fe6e9)
2026-09-27T06:28:45Z — SEALED Block 6: OTS proof attested in Bitcoin block 968723 (2026-09-26T17:42:26+00:00), merkle root confirmed against the chain; rail page re-rendered
2026-09-27T06:28:45Z — SEALED anchor confirmation banked: kind-3 3184270 (two-source merkle check)
2026-09-27T22:15:36Z — SUPERSEDED superseded by JFD-20260927-CERT-00004 (kind-15 3199054; witnesses A9 0123ADA0 + A10 0123DC79). Reason: certificate rendered and sealed before the certified document's anchor confirmed, so it printed the anchor PENDING; re-issued as CERT v2 stating the Bitcoin block (operator order 2026-09-27). 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 Files moved to cc-drop\sealed\superseded (CERT-V2-REISSUE-20260927, 2026-09-27).
