Research-site protocol revision.
A history you can follow.
The amendment, site response and authorised review stay linked to the project.
Fictional process, people and events. This is an explanatory example, not a production evidence pack or a prescribed legal checklist.
Follow the sequence below, then inspect the document reference and review limits. This is a fictional explanatory record.
A site cannot reconstruct which revision was received and acknowledged before work continued.

The event is only
part of the evidence.
A production export needs its covered documents, participant and credential references, event hashes, pack signature and timestamp material where required. Device and network context are supporting data, not proof of identity on their own.
Check the protected record
Recompute the covered hashes. Verify the signature against an independently trusted key. Validate the timestamp token and its trust chain. Confirm the export's scope and any missing material.
