THIS DOCUMENT IS SUPERSEDED.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

The seal of record is now JFD-20260928-CERT-00008. This page stays published and this seal stays valid over its own bytes; it is simply no longer current.

Block 6 — Bitcoin anchor — ATTESTED

ATTESTED in Bitcoin block 968966 (2026-09-28T07:32:31+00:00).
Confirmation event not yet banked.

Verify it yourself

SHA-256 the file's bytes exactly as stored; it must equal the digest above.
Read ledger event 3207188 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

2026-09-28T06:16:10Z — SEALED kind-15 3207188 (GH-PIPELINE-001 run PP-005-ED2-PROD-20260928T061610Z-01ca235e)
2026-09-28T09:28:13Z — SEALED Block 6: OTS proof attested in Bitcoin block 968966 (2026-09-28T07:32:31+00:00), merkle root confirmed against the chain; rail page re-rendered
2026-09-28T20:25:50Z — SUPERSEDED superseded by JFD-20260928-CERT-00008 (kind-15 3218927; witnesses A9 0123ADA0 + A10 0123DC79).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 Files moved to cc-drop\sealed\superseded (CERT-V3-DESIGN-20260928, 2026-09-28).
