Not sure why but you seem to be the author of the "fast-import: add
'strip-if-invalid' mode to --signed-commits=<mode>" commit now:

fast-import: add 'strip-if-invalid' mode to --signed-commits=<mode>

Tools like `git filter-repo`[1] use `git fast-export` and
`git fast-import` to rewrite repository history. When rewriting
history using one such tool though, commit signatures might become
invalid because the commits they sign changed due to the changes
in the repository history made by the tool between the fast-export
and the fast-import steps.
