ATTESTED in Bitcoin block 970090 (2026-10-05T22:57:24+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 3375598 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.
