system-level
Deep architecture scope
System-level describes something operating at or affecting the most fundamental layer of a computer system, organization, or structure.
In computing, system-level access means control over the operating system itself rather than individual applications: system-level permissions, system-level changes.
The term extends to any context where you're working at the foundational layer rather than on top of it: system-level reforms, system-level thinking.
