What is measured is what a manifest declares, not what a piece of software does. This registry fetches no repository URL, no endpoint and no package index; nothing here is verified. Which value comes from which source, and by which rule it was formed, is set out in the Methodology.

The image is drawn again on every request, so it always reports the current state while the pasted line stays as it is. It carries no rating and no traffic light – only the two measured figures.
