File	Issue
PR	Description explains the work — The PR description contains only the empty pull request template with no human-written explanation of the change. Fix: Add a brief human-written summary of what the PR does, e.g., "Adds a changelog entry for the new account-scoped firewall events dataset in Logs."
PR	Description scope accuracy — The title indicates the PR adds a changelog for account-scoped firewall events, but the description does not mention this core change at all. Fix: Update the description to confirm the changelog addition and the Logs area it affects.
