Read the history. Then inspect its integrity.Start with the participants, exact document versions and recorded responses. The technical checks below explain what protected content can be tested and what the specimen cannot prove.
Why the record matters
A file can be edited.
The change must be detectable.
If a record is changed later, a reviewer needs to be able to detect the difference. Compare this original sample with a deliberately altered copy. You do not need to edit anything.
The example below demonstrates a content fingerprint check. Full evidence verification also checks signatures, document links and independent timestamps. Explore the technical download if you need those details.
Original compared with changed copy
A change leaves a difference.

How a real reviewer checks a real pack
Several checks.
No blind trust in a PDF.
Event sequence and content
Recompute the event hashes and check links and the declared snapshot boundary. This does not reveal events never captured.
Pack signature and trusted key
Recompute the protected pack digest and verify the Ed25519 signature using an independently trusted signing key, not just a key bundled with the file.
Independent timestamp
Validate the RFC3161 token, its message imprint and the TSA certificate chain using suitable trust material. Check policy and validity requirements.
Protected PDF and attachments
Check the rendered artifacts against their signed seal where supported by the pack format. A visually plausible PDF alone is not proof.
Scope and meaning
Review the format version, exclusions, test flags and captured coverage. Device/user-agent and IP metadata do not by themselves prove which person operated the device.
Integrity is not truth, completeness or a legal outcome. Hashes alone can be recomputed after an edit; trusted signatures and independent timestamp validation are essential additional controls. Key compromise and trust configuration remain material assumptions.
Implementation basis: current local format-4 signing-pack descriptor and offline verifier inspected 28 September 2026. This does not establish production deployment or universal capture of every human action.
Do not just read the promise.
Inspect what supports it.
