What the reviewer found
Bash coding-guidance: 'curl | sh' is shown as FORBIDDEN with a verify-checksum-then-run correct form, 'no rm -rf on unset vars' is a defensive rule, and the sudo apt-get/curl shfmt lines install named CI tools. All defensive or benign examples.

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.
