Verification chain
Four things are pinned, and each can be checked independently of the others.
The assessment PDF. SHA-256: 3136bd770cc44f32da3ceaec48431f84bd32efbf6c3fde04165d16d996d4cf7a
Download the file and run shasum -a 256 over it. If the value differs, the file is not the one struck here.
The timestamp. The receipt AOS-HCD-2026-001-v1.0.pdf.ots is an OpenTimestamps proof over exactly those bytes, submitted to four calendars on 28 August 2026 and pending confirmation in the Bitcoin blockchain at the time of publication. It establishes that the file existed no later than the moment it was stamped. It establishes nothing about whether the file is correct.
The assessed source. The assessment rests on 20 pinned artefacts: all 20 retrieved and pinned by this case. All 20 are pinned by hash and 4 of the 20 are themselves Internet Archive captures. Quotations were checked against page images, not against a text layer alone; vocabulary counts state the artefact they were taken from and the control word run on the same extraction.

Of the 20 pinned artefacts, 4 are themselves third-party archive captures - R-IA-20260106, R-IA-CDX, R-IA-CDX-DEED, R-IA-20220307043937 - retrieved from the Internet Archive rather than from a publisher, and a reader can re-fetch each of those from that archive at the address the register records. The other 16 were retrieved from the publisher, and no independent capture of them is pinned here; for those 16 a reader must rely on this site or on the publisher’s server.
The build. The PDF is produced deterministically from tracked source by build.sh, with SOURCE_DATE_EPOCH pinned to the assessment date. Repeat builds on one machine and one toolchain are byte-identical; independent third-party reproducibility is not established and is not claimed. Verify by SHA-256, not by rebuild.
Version history
One version. The assessment date and the publication date are both recorded, and here they are the same day.
| Version | Assessed | Published | SHA-256 | Status |
|---|---|---|---|---|
| v1.0 | 28 August 2026 | 28 August 2026 | 3136bd770cc44f32da3ceaec48431f84bd32efbf6c3fde04165d16d996d4cf7a | current · download |
The cover carries 28 August 2026, the date the assessment was made, and publication followed the same day. An assessment is a reading of a source at a moment, and the document’s retrieval times and viewed dates already fix that moment; the cover is not moved to the upload date, because that would put two dates on one act of reading.
Corrections
None. This is the first edition and it has not been corrected since publication. Any correction to this assessment will be recorded here and in the practice’s corrections register, and the published bytes of this version will not move.
Corrections made before publication are not listed here. They are recorded in the case’s own pre-insertion audit and pre-publication audit, which are tracked with the source.
