Method

How Verify works

Read

Verify reads the repository at a pinned commit: settings, rulesets, workflows, and files.

Judge

Each control is checked against a written expectation. Same inspector, same criteria, every repository.

Prove

Every result shows the evidence Verify read. Assessments re-run daily, and changes are logged.
