The artifact

SHA-256 (final bytes, verbatim): 5fce853d41e00271741d7fd201c0fcac1056daf4f46344583f3166584493a33e
SHA-256 over the delivered PDF bytes VERBATIM (raw bytes, no normalisation). The seal page (Blocks 1-4) is inside these bytes; Blocks 4 live cells, 5 and 6 live on the ledger and the verify page. Reproduce by hashing the file as-is.

Block 1 — Author

K. L. Phillips, a man — the scanned hand is inside the sealed bytes (last page).

Block 2 — Issuer

ISSUER	Jet Fyul Dynamics LLC · Wyoming
RAIL	Matchstick Tribunal
CUSTODY	both witness keys held by the issuer, in silicon, on separate hosts; never exported

Block 3 — Rail seal (as printed)

The circular seal on the last page reads LEDGER EVENT 2962781 (the seal of record, pass 1) and STAMPED. The final bytes are sealed by event 2962786 (pass 2). Two-pass seal: pass 1 sealed the page with the event field pending; pass 2 sealed the page carrying that id.

Verify it yourself

SHA-256 the delivered PDF exactly as received; it must equal the digest above.
Read ledger event 2962786 by id; its payload's doc_sha256 must be the same digest, its hardware_signatures the two entries above.
Verify each witness signature offline: ECDSA P-256 over the seal-request bytes named in the payload, against the public key above — no contact with us needed.
Run ots verify with the .ots proof; when ATTESTED, the Bitcoin block is the timestamp.

2026-09-17T11:28:01Z — SEALED Block 6: OTS proof attested in Bitcoin block 967393 (2026-09-17T10:03:01+00:00), merkle root confirmed against the chain; rail page re-rendered
2026-09-18T16:40:07Z — SUPERSEDED superseded by JFD-20260917-CERT-00002 (pass-1 2962820, final 2962825; witnesses A9 0123ADA0 + A10 0123DC79). Reason: the sealing path dropped the embedded PP-003-Proof-Posit.md and .ots attachments, and the declaration was dated 16 September though signed 17 September. 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 Files moved to cc-drop\sealed\superseded (GH-CLOSE-STATIONS A3, 2026-09-18).
