### All commits must be signed
#### How to fix:
1. **Configure commit signing** (if not already done):
\`\`\`bash
# For GPG signing
git config --global commit.gpgsign true
# Or for SSH signing (Git 2.34+)
git config --global gpg.format ssh
git config --global user.signingkey ~/.ssh/id_ed25519.pub
\`\`\`
2. **Re-sign your commits:**
\`\`\`bash
git rebase -i origin/main --exec "git commit --amend --no-edit -S"
git push --force-with-lease
\`\`\`
