And if the SPDX stuff *isn't* redundant, it needs to be listed somewhere else for humans. > +Signed-off-by Restriction > +------------------------- > + > +Coding assistants **MUST NOT** add a ``Signed-off-by`` tag pointing to themselves.

The agent's contribution is acknowledged through the ``Co-developed-by`` tag as described below. This is unique to Agents.

This is fine too. But like I said before, you must update checkpatch.pl to not complain about Co-developed-by missing S-o-b when C-d-b lacks email address, and it should be part of this series. -Kees -- Kees Cook
