Verification hub

Certificate registry

Approved-for-publication certificates and their current status.

What is listed here

This registry lists only certificates approved for publication. A certificate that has not been approved for publication does not appear, and its absence is not a statement about its contents.

Status labels

• Active - current and unamended.
• Corrected - amended under the correction process, with the correction attached.
• Void - the protocol moved after measurement or a seal condition failed.
• Retired - superseded and no longer current, retained for the record.
• Internal-only - not published, and not listed here.

What a listing never contains

No raw answer text and no screenshots of a subject's material appear in this registry. The registry carries the seal, the status, and the verification path.

Seals predating 2026-08-24

Seals issued before 2026-08-24 are internal-only. They are never listed here and are not published in any form.
