'signed-off-by' is a linux kernel convention; by adding your Signed-off-by line to a patch, you are certifying that you have read and understood the Developer Certificate of Origin (DCO), originated in 2004 by the Linux foundation as an affirmation that the source code being submitted originated from the developer, or that the developer has permission to submit the code. Many projects follow the same conventions used by the linux kernel.

I would have expected that the "who wrote" is obvious from the Author:
line in the commit, "who reviewed" by something like "Reviewed-by:" and
the committer from the Committer line.

For the projects I usually interact with Signed-off-by has a juristic
meaning, see my mail from Monday.

If the Signed-off-by here really only has the purpose to show through
which hands the patch went in, I can resend of course.

Best regards
Uwe
