What the reviewer found
GitHub Actions CI/CD best-practices guide: the flagged HTML comment is just a closing section marker, not a hidden directive, and the rm -rf is generic Dockerfile-layer cleanup advice, not a command run anywhere. Pure documentation.

How this review was made
Sonnet 5 read the files above on 7 September 2026 and answered three questions: is it dangerous to whoever installs it, is each scanner finding real, and what should the installer know. The verdict is bound to the file's hash; when the file changes, it is scanned afresh and reviewed again. A script that changes while the definition does not is not re-reviewed — that is a known gap. How the scan and the review work.
