The recording saves to the permit file with everything else. Six months later, when someone asks what was agreed and on what basis, the answer is a video of the actual ground with the approver's voice on it.
What was actually seen
Not a description of the site. The site, on camera, at the moment of the decision.
Who agreed to what
The approver's voice, their conditions and their signature, all in one artefact.
Why the category was cleared
The evidence on screen when the decision was made, preserved with the decision.
Available for audit
Attached to the permit and reachable from the Subsurface record, years later.
