⚠️ Signed-off-by Validation Issues

The following commits have issues with their Signed-off-by lines:

• Commit 7b6002b: Commit author email (jfrob@users.noreply.github.com) not found in any Signed-off-by line

Please add a proper Signed-off-by: Your Name <your.email@example.com> line to each commit message.

Missing correct Signed-off-by line

This pull request has commits that are missing proper Signed-off-by lines or use invalid email addresses.

Requirements:

• Each commit must include at least one Signed-off-by: Your Name <your.email@example.com> line
• Commit author email must appear in at least one Signed-off-by line
• Commit committer email must appear in at least one Signed-off-by line (if not a GitHub bot)
• Multiple Signed-off-by lines are allowed for co-authored commits
• Anonymous GitHub emails (like @users.noreply.github.com) are not allowed
• The Signed-off-by line indicates that you agree to the Developer Certificate of Origin (DCO)

How to fix:

# Configure your git identity first (if needed):
git config user.name "Your Name"
git config user.email "your.email@example.com"

# For the last commit:
git commit --amend --signoff

# For multiple commits, use interactive rebase:
git rebase -i HEAD~N --signoff

# For co-authored commits, add multiple Signed-off-by lines manually:
git commit --amend
# Then add in the commit message:
# Signed-off-by: Author One <author1@example.com>
# Signed-off-by: Author Two <author2@example.com>

# Then force push:
git push --force-with-lease

Does this still need something from me or is the check just broken?
