What this excerpt selects

What this excerpt selects
Required secrets declaredno
derived from: Required secret variables (raw)

A derived value carries its raw declaration beside it; the derivation rule is published, with a version, on the methodology page.

What this excerpt does not say

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.
