The DCO CI check is still failing because:

Commit sha: 2face26, Author: Pepper Gray, Committer: Pepper Gray; Expected "Pepper Gray 111446242+peppergrayxyz@users.noreply.github.com", but got "Pepper Gray hello@peppergray.xyz".

You need to make the author of the commit match the Signed-off-by - I think this is a setting in GitHub, where it uses their generated noreply email address.

This doesn't really work, by default CC will be cc (at least on GNU Make) which means this assignment will never happen.
