Block 6 — Bitcoin anchor — ATTESTED

ATTESTED in Bitcoin block 968959 (2026-09-28T06:51:47+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 3206670 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.

2026-09-28T20:27:17Z — SUPERSEDED superseded by JFD-20260928-CERT-00011 (kind-15 3218951; witnesses A9 0123ADA0 + A10 0123DC79).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 Files moved to cc-drop\sealed\superseded (CERT-V3-DESIGN-20260928, 2026-09-28).
