Summary

• PR trigger: Workflow now runs on pull_request to main, so authors can preview PDFs before merging
• PR comment: Bot automatically comments on PRs with a link to download the generated PDF from artifacts
• Commit PDF to repo: On push to main, the generated paper.pdf is committed back to the repository so it's always available at paper/paper.pdf without needing to download artifacts (uses [skip ci] to prevent infinite loop)
• Better validation: Consolidates the 4 separate sed | grep steps into one validation step with clear error messages listing all missing fields at once, with a link to the submitter guide
• Artifact rename: Changed from "PDF and info.txt" to "paper" for clarity

Before

• Workflow only ran on push to main
• Authors had to merge first, then check Actions for the PDF
• PDF only available as an artifact that expires after 90 days
• Each missing metadata field failed separately with no helpful message

After

Trigger	Behaviour
Push to main	Build PDF → upload artifact → commit paper.pdf to repo
Pull request	Build PDF → upload artifact → bot comments with download link

• All missing fields reported at once with a link to documentation
• PDF always available in the repo at paper/paper.pdf

Test plan

• Open a test PR to verify the workflow triggers on PRs
• Verify the bot comment appears with the correct artifact link
• Verify push to main commits paper.pdf back to the repo
• Verify the [skip ci] prevents infinite workflow loop
• Test with missing metadata fields to verify validation error messages
