Generally looks good to me, but the commits don't seem to be signed.

That is not an AI artefact. I have no idea why that sometimes happens. This started a few weeks ago. Something with my config must be borked and I alread ylooked but everything looks as always.

I can probably rewrite them and force push if you prefer?

Mhm weird indeed. My (global) config has this, which has been working fine:

[user]
  email = <YOUR_EMAIL>
  name = <YOUR NAME>
  signingkey = <KEY ID>

[commit]
  gpgsign = true

You actually have to do this, otherwise we would need to disable signed commits (which I argue we don't want, even if temporary). So yes re-signing and re-pushing them is the way to go. Basically do this:

git rebase --exec 'git commit --amend --no-edit --no-verify --gpg-sign' origin/main
git push --force-with-lease
