What the reviewer found
Dockerfile-optimization guide: the root check is a verification step confirming the container does NOT run as root, the curl|sh mention is hadolint (DL4006) advice about pipefail in Dockerfiles, and rm -rf is scoped to the apt cache (`/var/lib/apt/lists/*`) inside a build layer. No credential access or exfiltration anywhere in the file.

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.
