This is the investing section of the formula verification report, which explains what each kind of case tests, how the counts are produced and what they do not prove. Rows run from the largest suite to the smallest; each row's address ends in the calculator's slug, so one calculator's evidence can be linked and cited on its own. The test file behind every row, and the per-kind numbers, are in the machine-readable report.
