• When no adoc is modified, do not skip commenting. Instead, a no-error comment shall be published.
• Switching to disco-ball-style commenting from the GitHub workflow file using refresh-message-position: true would improve timeline clarity.

• In the table, where a link to a specific line in a file exists, if the file hasn't been modified in this PR, link it to the file in the specified branch instead of the "files changed" version.
