Every key claim,
with evidence.

Proof Lens is planned for Peak Docs: making key claims traceable to their evidence. This page shows the concept as a way to check, with a fictitious example.

The claim first,
then the evidence.

The sculpture is an illustration, not study evidence.
The starting point

Can everyone see what this claim rests on?

Proof Lens is meant to connect claims in a document with their evidence. It is planned and not available today. Until then you record evidence in Peak Docs as a link or reference at the sentence, doubts as a comment and decisions in the decision block.
