What's the difference between git author and committer?

TL;DR

author wrote the code (make the patch) commiter commit it to the repo (rewrite history, make pull/merge requests...)

Nice explanation: https://stackoverflow.com/questions/18750808/difference-between-author-and-committer-in-git

Very often developers make inaccurate commits with the one name/email (e.g. work account), then change to the right (e.g. personal account) and make git commit --amend, but forget to change the author of the commit. This way we can use it for OSINT as match of names/emails from git history.
