What the reviewer found
Dockerfile best-practices guidance: .aws/credentials appears in a .dockerignore that keeps secrets OUT of images, 'RUN curl | sh' is labeled an anti-pattern, rm -rf /var/lib/apt/lists/* is standard apt cache cleanup, and the wget is a HEALTHCHECK against localhost. All defensive or benign.

How this review was made
Fable 5.1 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.
