Applicability, Coverage, and Missing Evidence in Code Assurance Scoring

The Code Assurance Index (CAI) calculates a headline score from a producer-supplied evidence bundle. Measurements at dimension level are combined into categories; categories and direct meta-dimension inputs are combined into lenses; and the measured lens results enter an ordered weighted average (OWA) that produces the headline score and its reporting band. Evidence that is absent, partly covered or incomplete at different stages of this process has different arithmetic and interpretive consequences.
