A branch URL serves whatever the branch holds now, and a platform that rehosts your images keeps its copy forever. The pin must be immutable.
Your sitemap ping has a daily budget

Your deploy output is a verification surface
A deploy that exits zero proves the commands ran, not that anything shipped. Print the counts that would differ between a real deploy and a no-op.
