SYSE.33:2 - Problem

A setup instruction can omit the package installed months ago, a manually altered service, a local credential or a shared fixture. Copying the machine then reproduces some of its history without explaining which conditions the task requires.

Infrastructure descriptions solve only part of the problem. A declared database is not its retained contents, a secret reference is not granted access, and a running machine is not evidence that the intended test can execute. Partial creation and configuration drift make these distinctions consequential.
