A derived value carries its original data beside it; the derivation rule is published, with a version, on the methodology page.
Caveats, distribution and query
What this category does not say
- Environment variables (raw) is the complete, sorted enumeration of what a manifest declares. So "nothing declared" means exactly that and nothing else: an entry that also declares something different is not in this category.
- The empty value means "the source explicitly declares nothing here". It does not mean "not recorded": what was never recorded is in no category of this property.
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.
Every sentence here follows from the condition above, not from an assessment.
