THIS DOCUMENT IS SUPERSEDED.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

The seal of record is now JFD-20260929-PP-00002. This page stays published and this seal stays valid over its own bytes; it is simply no longer current.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): a473914fd5e8a71526aab2dc6930c192bb54532bcd191c94a24fbe3b8fe83596
SHA-256 over the file RAW BYTES AS STORED, verbatim. The document is the final render (R2(b)): the full text of its exact source set as readable pages, the SHA-256 of that source printed in every page footer, and the author's signature on the cover. The sealed bytes carry no seal outcome: the ledger event, the seal page, the certificate and the verify page carry it.

Block 6 — Bitcoin anchor — ATTESTED

ATTESTED in Bitcoin block 968957 (2026-09-28T06:28:25Z).
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 3206405 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.

Certificate

Bound with its certificate in one sealed PDF, DCN JFD-20260928-CERT-00008, sealing event 3218927. Its verify page.

Supersession

This version supersedes JFD-20260926-PP-00001, digest 530a8f9569113791289c92ff5a9380d4f0b60919d52cfa52da992651c8e57da9 (ledger event 3171889).
Reason: JFD-20260928-PP-00002 is a new edition of JFD-20260926-PP-00001. 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. The earlier edition's seal stays valid over its own bytes; it is no longer the seal of record.

History

2026-09-28T06:16:10Z — SEALED kind-15 3206405 (GH-PIPELINE-001 run PP-005-ED2-PROD-20260928T061610Z-01ca235e)
2026-09-28T06:16:10Z — SEALED anchor confirmed (G5-ANCHORED) in Bitcoin block 968957 before certificate JFD-20260928-CERT-00006
20260928T204408Z — SEALED certificate of record is now JFD-20260928-CERT-00008 (re-issued on the design of record, CERT-V3-DESIGN-20260928; supersedes JFD-20260928-CERT-00006); nothing about this document changed
2026-09-29T06:43:49Z — SUPERSEDED superseded by JFD-20260929-PP-00002 (kind-15 3225503; witnesses A9 0123ADA0 + A10 0123DC79). Reason: superseded by the third edition (JFD-20260929-PP-00002): The third edition removes the second edition's unfilled masthead date and seal-record slot lines and points to its verification page and certificate; 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-20260929-PRESS-CLEAR, 2026-09-29).
