What a signature proves

We are precise about the limits.

A signature proves a Signata pack has not been altered since it was signed, and that each claim came from the source excerpt included with it.

It does not prove that a source document is genuine. Authenticity is established by the counsel who signs off, and, where they exist, by digitally signed sources such as registry extracts.

Signed Signata packs are in development. This is the standard they are being built to.
