The issue names Fargate and CIS-hardened base OS support but mentions no repository files, tests, or entry points. Start by researching the Fargate platform constraints and existing AWS documentation; done would require a defined, supported way to run Fargate on a CIS-hardened image or documented compliance assurance.
