Why it matters in practice
Consent controls should correspond to what scripts and storage mechanisms actually do. If a preference is collected but optional technologies continue to run, the interface and system behavior diverge. Teams should test the complete page lifecycle and distinguish necessary storage from optional purposes under the rules relevant to their service.
Example
A visitor declines optional measurement, and a test confirms that the corresponding non-essential tag does not start on the next page.
