FP-006-CERT · rail DCN JFD-20260926-CERT-00005 · status SUPERSEDED · seal v2, exact-bytes lane (GH-PIPELINE-001)

THIS DOCUMENT IS SUPERSEDED.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

The seal of record is now JFD-20260927-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 This page stays published and this seal stays valid over its own bytes; it is simply no longer current.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): 810553131fdc2ce1d002b9a0be06fc05d4f4b996d492176fe8dbb9a831518c8f
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 968728 (2026-09-26T18:34:59+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 3173086 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.

History

2026-09-26T18:21:10Z — SEALED kind-15 3173086 (GH-PIPELINE-001 run FP-006-FREE-PROD-20260926T182110Z-51303176)
2026-09-27T06:28:45Z — SEALED Block 6: OTS proof attested in Bitcoin block 968728 (2026-09-26T18:34:59+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)
2026-09-27T22:16:43Z — SUPERSEDED superseded by JFD-20260927-CERT-00007 (kind-15 3199076; witnesses A9 0123ADA0 + A10 0123DC79).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 Files moved to cc-drop\sealed\superseded (CERT-V2-REISSUE-20260927, 2026-09-27).
